The next resource priority scheduled for a Board workshop is the management of invasive species. After reviewing resource management policies originally adopted by the Board in 1994, staff recommends revising the existing Non-native Species Management chapter(Chapter 6). The proposed invasive species management policy text is attached. Revisions to Chapter 6 are presented in a strikeout/underline version. The order of the policies has been rearranged to fit within the current approach of addressing these issues under prevention, monitoring and control topics. As a result, some of the former policies have been relocated, in addition to being revised or completely replaced. Staff is recommending that any inconsistencies within the resource management policies that arise because of sequential revisions to different sections be addressed at the conclusion of all the specific policy workshops. CEQA COMPLIANCE The study session will not result in any action by the Board of Directors subject to CEQA compliance.

GENERAL MANAGER'S RECOMMENDATIO I. Accept consultant's report in implementation of a digital simulcast two-way radio system for the District. 2. Approve the five-year plan for improvement of the radio system in concept. 3. Direct district staff to obtain more detailed estimates from the consultant in order to present this information to the Administration and Budget Committee as a part of the 2007/2008 budget preparation process. BACKGROUND In October 2005, staff solicited Request for Proposals (RFP's) for a Needs Assessment and Plan for Improvement of the District's Two Way Radio System. The proposal from Macro Corporation was the best proposal in both content and price. Macro came highly recommended by both San Mateo County and the City of Sunnyvale. Macro has also completed similar projects for other public agencies. Macro's contract fee of$21,998 was within the budgeted amount and less than $25,000, and therefore within the General Manager's spending authority. On December 2, 2005, the District entered into an agreement with Macro Corporation to complete a comprehensive study to evaluate the District's current two-way radio communications system, assessing the needs of its users, and recommending strategies for possible system upgrades of the District's two-way radio system. Macro completed their report on May 10, 2006, which is the basis of the proposed plan. A committee made up of field staff, Support Services Supervisor and the Operations Manager assisted in the development and evaluation of the RFP's and worked with Macro providing valuable input on the needs and problems of the current radio system. This input was used by Macro in their evaluation and final report. The District requested that Santa Clara County Communication review Macro's final report and provide comments. Santa Clara County received a fee for this review. In their written report to the District, Santa Clara County Communications felt the overall report was excellent. They felt it was written with clear and concise language. They reconsidered that their recommendations are appropriate and fully support the recommendation for a digital simulcast radio system. R-07-10 Page 2 The District operates a single frequency pair (channel) analog radio system, consisting of five stand-alone repeater(tower) sites and over 100 vehicular,and portable radios. The District contracts with the City of Mountain View for dispatching services. The District's current radio system was developed in the early 1990s when the District's growth exceeded the capabilities of sharing the Santa Clara County Parks radio system. The current radio system is based on a community repeater system on the District's own frequency, licensed by the Federal Communication Commission (FCC). A community repeater allows one group of uses (patrol) to mute messages from the other group (maintenance) to reduce distractions. However, only one group of users can communicate at a time, since there is only a single channel available. A community repeater operation also provides a significant benefit to Mountain View Dispatch. It allows dispatch to hear only messages from patrol, thereby limiting any distractions from maintenance messages. This is important, because a single Mountain View dispatcher must monitor numerous public safety channels simultaneously (District patrol messages as well as those from the city police or fire). Ideally, if the District had two channels there would not be the need for a community repeater. It took many years and a tremendous amount of effort to obtain our current channel. The District has been trying for many years to obtain another channel from the FCC and the outlook is not good. This is due in large part to the scarcity of frequencies that can be used over the large areas covered by the District. Numerous mountaintops within the District would probably cause interference with other agencies within the hundreds of miles covered. The loss of community repeater operation, without replacing it with an equivalent function, would significantly impact Mountain View Dispatch and field operations. Dispatchers and field users would have to sort through every message on the radio channel to determine whether it involves them or not. District field operations also require "wide-area communications." Wide-area communications is the ability of a radio system to allow two or more field users in different geographic areas to communicate, when they are not in range of the same communications tower site. District supervisors are responsible for incidents occurring District-wide and must be able to talk and listen to all units. Field staff responds to emergencies and fires throughout the District, requiring them to communicate with staff within the entire boundary area of the District. The District's current radio system is analog. Some agencies that the District communicates with have changed or are in the process of changing to digital format, i.e. CDF and Santa Clara County Sheriff's Office. Once another agency switches to a digital signal the District can no longer communicate by means of radio without a digital radio. Digital radios have the ability to communicate with both analog and digital format radio systems provided they are on the same frequency band. Staff has been aware of newly enacted Federal Communication Commission (FCC) regulations that will require the District to either modify the legacy analog equipment to "narrowband" operation (and replace some models that are incapable of such modification), or eventually replace the analog equipment with digital models that are inherently narrowband. Narrowband refers to a radio signal which occupies only a small amount of space on the radio spectrum, thereby making it more efficient. R-07-10 Page 3 DISCUSSION The following discussion outlines Macro's findings, including alternatives to address deficiencies found in the current system. Alternatives include changes necessary to comply with FCC regulations. The conclusion of the Macro Corp. report contains a recommendation for a Digital Simulcast radio system with vehicular mobile repeaters. The report advises that this will best meet the needs of the District for current operation and will provide the ability to grow with the District long into the future. Purpose of Report The purpose of Macro's report was to evaluate the District's current two-way radio communications system, assessing the needs of its users, and recommending strategies for possible system upgrades and/or replacement. The report describes the findings and presents various upgrade and/or replacement strategies that will address the needs of the radio system users, as well as comply with mandatory Federal Communications Commission spectrum efficiency standards that become effective in the near future. The following discussion details Macro's recommendation that the District implement a digital simulcast two-way radio system, based on the two major deficiencies found in the current system: over-transmission and poor coverage. Report Findings Macro's report validated the two most significant system deficiencies noted by District staff. These were over-transmission problems and poor coverage. "Over-transmission" refers to the collision of two or more messages on a radio channel. It occurs when a dispatcher or field user, unable to hear an ongoing conversation on the channel, attempts to make a radio call. This results in one or both messages becoming garbled and possibly lost. It is caused by limitations associated with analog community repeater operation, as well as the current configuration of stand-alone tower site repeaters. The over-transmission problem is a safety concern to patrol. Simulcast technology would allow all field users to hear all messages if in range of any tower site. Having a"digital" simulcast system will enable the District to maintain a community repeater operation. Most of the "poor coverage" areas were associated with the use of portable radios, which is to be expected to a certain degree. However, in many areas, Macro found that the tower site signals were strong enough to support communications using a vehicular radio. In these specific cases, a device called a mobile repeater could be used to enhance portable radio coverage when the portable radio user is near his/her vehicle. Mobile repeaters are devices that are installed in a vehicle that can relay a portable radio's signal to the tower site using the higher-powered vehicular radio. There were a number of areas where Macro's findings conflicted with user reports of poor coverage. In these cases, the tower site equipment should be tested to verify operation. However, some cases may be the result of limitations associated with the District's current stand-alone tower site repeaters. If a user is not in range of a particular tower site, he/she will miss all messages routed through that tower site. A similar problem can also occur when a field user forgets to select the closest tower and unknowingly tries to activate a more distant tower site repeater. Such messages will be difficult to understand or missed entirely. R-07-10 Page 4 Although Macro feels the current system worked well in the past, it believes these problems will worsen as the District's jurisdictional area grows and tower sites are added. Thus, the District is approaching the point where a more comprehensive solution is required. Regulatory Impacts Recent Federal Communications Commission (FCC) regulatory changes will require the District to make changes to its radio system. Effective January 1, 2011, the District will not be permitted to expand the coverage area of its current system, unless it converts to more spectrally efficient technology. ("Narrowband" refers to a signal that occupies only a small amount of space on the radio spectrum -- 12.5 kHz bandwidth, in contrast to "Wideband"that occupies 25 kHz bandwidth, narrowband thereby being "spectrum efficient.") Concurrently, the FCC will prohibit manufacture and importation of equipment not meeting specific spectrum efficiency standards. Furthermore, the FCC has established January 1, 2013 as the mandatory deadline for final conversion to more efficient technology. Thus, the District will not be permitted to operate in its current "legacy" (wideband) mode of operation after this date. Compliance will require the District to either modify its legacy analog equipment to "narrowband" operation (and replace some models that are incapable of such modification), or eventually replace its analog equipment with digital models that are inherently narrowband. Continuing to operate analog equipment has certain limitations, but is the least costly approach. Digital operation eliminates some potential risks associated with converting analog equipment, but is more costly. Alternatives Macro provided four alternatives to meet upcoming regulatory requirements as well as provide operational options that target some of the system deficiencies noted in their report. Estimated total costs are included. Each alternative is based on the following assumptions and considerations unless otherwise noted: • 150 MHz frequency band • Meet anticipated FCC spectrum efficiency requirements • Utilize the same tower sites as in use today • Equipment quantities based on current inventory (includes spares) • Assumes new antennas at all sites • No backup battery systems are provided at tower sites (none exist today; only generators) Costs include sales tax, installation, vendor engineering and project management, and professional (consulting) efforts, such as vendor proposal review and vendor oversight/project Alternative A—Maintain the Status Quo. This alternative continues operation of the current technology and includes steps to meet all upcoming regulatory requirements. Estimated cost is $369,000. PRO: • Maximizes reuse of existing fixed and user equipment • Many brands and tiers of user equipment expected to be available through 2009 • Open standards-based analog operation promotes interoperability R-07-10 Page 5 • Simple to maintain, allows for competitive outside maintenance contracts • Less costly (then other replacement alternatives) • Mobile repeaters can be added to reduce current portable radio dead spots CON: • Does not provide wide-area communications • Does not eliminate the over-transmission problem • Narrowband analog will reduce in coverage in current fringe areas • Vendor support for analog products will diminish after 2009 • New equipment models and options will diminish after 2009 • Radios cannot operate on any outside agency systems which are/or convert to, digital • Cannot support individual-calling, messaging or other advanced features • Narrowband analog is more susceptible to co-channel interference Alternative B—Migration to Digital Operation. This alternative is similar to above, but replaces the legacy 150 MHz analog systems with digital technology. Most of the District's equipment is incapable of digital operation, so most equipment would eventually require replacement. Selecting this alternative would not preclude the District from later upgrading to simulcast (Alternative D). Estimated cost is $406,000. PRO: • Coverage generally equivalent to current legacy system • Vendor support for digital products increasing • Latest equipment models will likely be digital • Digital radios are backward compatible with legacy and narrow analog systems • Enhances community repeater functionality • Project 25 Compliant (standardized digital radio technology to allow interoperability) • Mobile repeaters can be added to reduce current portable radio dead spots CON: • Does not provide wide-area communications • Does not eliminate the over-transmission problem • Requires replacement of some existing legacy equipment before the end of its useful life • Outside agencies incapable of digital could not communicate on frequency. • Fewer equipment models available today (temporary situation) • Some outside maintenance shops are not yet trained on digital (reduces pool of shops) • More costly than analog Alternative C—Analog Simulcast Operation_This alternative integrates all tower sites together through the use of existing Santa Clara and San Mateo County infrastructure equipment. Allows all radio messages to be automatically transmitted by all tower sites simultaneously. Estimated cost is $1,025,000.

Option 1: Implement mobile repeaters to reduce current portable dead spots. This option minimally equips the vehicle fleet (approximately 22 vehicles) with mobile repeaters. The cost for mobile extenders is $53,000. This option is not included in the estimates above. Macro recommends a"pilot project" by implementing with a couple of units to evaluate their performance before expansion to more fleet vehicles. Mobile repeater will require licensing of an additional low power radio frequency. Option 2: Purchase and install tower site repeaters to cover dead spots in current and future growth areas. This option installs new tower site repeaters to fill existing coverage "dead spots" in the current jurisdictional areas, and in the future San Mateo County coastal R-07-10 Page 7 region. Fewer tower site repeaters may be needed if mobile repeaters are implemented under Option 1, or if digital options are chosen. Integrates all repeaters together using a receiver comparator to simplify operation. This option is not included in the estimates above. The estimated additional cost is $350,000. Option 3: License a frequency pair (second channel) or other alternative for maintenance traffic. This option licenses an additional radio channel to separate patrol and maintenance onto separate discreet channels to reduce over-transmission problems and eliminate community repeater operation. This option is not included in the estimates above. The estimated additional cost is $187,OOO.This option may be difficult, if not impossible, to implement at this time because of difficulty obtaining a second frequency. FCC laws requiring spectrally efficient technology may provide better opportunities for an additional frequency in the future. Macro's Recommendations Macro has recommended implementing Alternative B (Migration to Digital Operation), with a commitment and intent to pursue simulcast technology as described under Alternative C or Alternative D. Digital technology will have increasing support from vendors over time. Digital operation can be phased in over time by purchasing digital-capable portable, vehicular and repeater equipment going forward, but operating this equipment in analog mode in the near term (digital radios are capable of analog operation so they will remain compatible with the older radios that are still in operation during the transition to digital). Simulcast technology solves the over-transmission problem and provides wide-area communications. Simulcast allows all field users to hear all messages if in range of any tower site. Digital maintains a community repeater operation and meets FCC requirements for spectrum efficiency. Digital will suffer less performance degradation compared to analog technology when the District converts to FCC-mandated"narrowband". Mobile repeaters will addresses the current problem of portable radio dead spots. Implementing Alternative B also leaves the District's options open to implementing either type of simulcast technology (analog or digital) in the future, as described in Alternative C or D. Most importantly, simulcast solves the current over-transmission problems, provides wide-area communications and will simplify system operation as the radio system inevitably expands. Simulcast technology allows all field users to hear all messages if in range of any tower site. Simulcast can completely eliminate over-transmission problems and can provide seamless wide- area communications as required by patrol. Simulcast requires more equipment at each radio site, and reliable "backhaul" (site connectivity) links to connect the tower sites together and to a central point. Although simulcast simplifies system operation from a user's standpoint, it is more complicated than what is in place today. Thus, recurring costs are likely to increase under either simulcast alternative. Macro also recommends adding the mobile repeaters option. This could reduce the need to construct additional repeater sites to solve some portable radio coverage problems. Consider conducting a"pilot project" by implementing a couple of units to evaluate their performance for possible expansion to more fleet vehicles. R-07-10 Pagc 8 Macro recommends that the District continue its attempt to license an additional channel to provide flexibility (Option 3 above). A secondary frequency pair (channel) could eliminate community repeater operation, which would promote certain alternatives above. Due to a shortage of frequencies in the Bay Area, such efforts are considered long-term at best. Converting to digital can begin today. Since the vast majority of these models are backward compatible with both the legacy analog operation, as well as narrowband analog operation, these models will operate on the current legacy system as well. This fact also permits these radios to operate with other external radio systems, such as with CDF, for the long term. Cost Migration from Analog to Digital Simulcast Radio System Macro was originally requested by staff to provide a 12-year implementation plan for the four alternatives. After further consideration Macro was asked to develop an accelerated five-year Master Plan for Alternative D. Macro has provided cost estimates for a five-year implementation plan. Total estimated cost is $1,334,030. This includes the $1,037,000 from Alternative D above, plus mobile repeater option and annual tower leases and equipment maintenance for five years.

These models will operate on the current legacy system as well. This fact also permits these radios to operate on other external radio systems, both analog and digital, such as CDF and Santa Clara County Fire.

EXECUTIVE SUMMARY The Midpeninsula Regional Open Space District has contracted with Macro Corporation for assistance is evaluating its current two-way radio communications system, assessing the needs of its users, and recommending strategies for possible system upgrades and/or replacement. This report describes our findings and presents various upgrade and/or replacement strategies that will address the needs of the radio systems users, as well as comply with mandatory Federal Communications Commission spectrum efficiency standards that become effective in the near future. Background The District operates a single channel analog radio system, consisting of five stand-alone repeater (tower) sites and over 100 vehicular and portable radios. The District contracts with the City of Mountain View for patrol dispatching services. Maintenance and Rangers (referred to as "Patrol") share use of this radio channel. Users are able to mute messages from the other user group to reduce distractions. However, only one group of users can communicate at a time since there is only a single channel available. This configuration is referred to as Community Repeater operation. Community Repeater operation also provides a significant benefit to Mountain View Dispatch. It allows dispatch to only hear messages from Patrol, thereby limiting the number of distractions from Maintenance messages. This is important, as a single Mountain View dispatcher must monitor numerous public safety channels simultaneously(District Patrol messages as well as those from the city Police or Fire). Field radios are equipped with up to 43 channels (see Appendix Q. Ten channel positions are used by the District to access one of the five repeater sites (five for the Maintenance group, five for Patrol). However, users must be trained and understand which repeater best serves the areas they may be operating in. An eleventh channel exists for communications directly between users in close range of each other (referred to as the"Tactical"channel). User Requirements Patrol's requirements include the need to communicate with Mountain View dispatch and with other patrol units throughout the District's jurisdictional area. This includes field supervisors that must be able to monitor events over a vehicular or portable radio from anywhere in the jurisdiction. As patrol officers are often away from their vehicles, they require reliable portable radio coverage to the extent achievable. Patrol and Maintenance occasionally communicate with the California Department of Forestry (CDF), Santa Clara County Parks, and other law and fire agencies. This level of interoperability must be maintained. Maintenance personnel typically need to communicate with others within the same area, and occasionally outside of that area. Unlike Patrol, Maintenance is not typically dispatched to their work locations via radio, and do not heavily rely on a specific office base station. Maintenance crews are more likely to be assigned to a specific work location in advance, or have more regular routines when compared to Patrol. Thus,a higher percentage of their messages will be localized. Improvement of the Two-Way Radio Communications System Page 1 Needs Assessment&Conceptual Design Report May 10, 2006 MADPENWOMA R60*0m*.L Ofth$P^M 04TRI" MACRO Mtn. View Dispatch is not currently configured to monitor Maintenance communications. However, Maintenance personnel can reach dispatch by using the Patrol radio channel that is present on all Maintenance radios. The two most significant system deficiencies noted by users were over-transmission problems and poor coverage. "Over-transmission" refers to the collision of two or more messages on a radio channel; it occurs when a dispatcher or field user, unaware of an ongoing conversation on the channel, attempts to make a radio call. This results in one or both messages becoming garbled and possibly lost. The over- transmission problem is a safety concern to Patrol. It is caused by limitations associated with analog Community Repeater operation, as well as the current configuration of stand-alone tower site repeaters. While this system configuration has worked well for the District,we expect these problems to worsen as the District's jurisdictional area grows and tower sites are added. Thus, the District is approaching the point where a more comprehensive solution will be required. Each of the Alternatives presented later in this report address these challenges. Most of the reported poor coverage areas were associated with the use of portable radios, which is to be expected to a certain degree. However, in many areas, Macro found that the tower site signals were strong enough to support communications using a vehicular radio.' In these specific cases, a device called a Mobile Repeater could be used to enhance portable radio coverage when the portable radio user is near their vehicle. Mobile Repeaters are devices that are installed in a vehicle that can relay a portable radio's signal to the tower site using the higher-powered vehicular radio. Users also identified areas having poor vehicular coverage. Our analysis showed that in most cases, terrain conditions were responsible for attenuating or blocking signals between the field user and their closest tower site. These problems can only be solved by the addition and/or relocation of tower sites. There were a number of areas where our findings conflicted with user reports of poor coverage. In some cases, we have recommended that the tower site equipment be tested to verify proper operation. However, some cases may be the result of limitations associated with stand-alone tower site repeaters. If a user is not in range of a particular tower site, they will miss all messages routed through that tower site. A similar problem can also occur when a field user forgets to select the closest tower and unknowingly tries to activate a more distant tower site repeater. Such messages will be difficult to understand or missed entirely. Integrating or networking the stand-alone tower sites together as a cohesive system could noticeably improve system performance. Networking would not increase the coverage "footprint" of the radio system per se — only additional tower sites can accomplish this. However, integration simply makes more effective use of the District's tower sites. There are two ways to accomplish this. A partial improvement could be realized by implementing a receiver comparator;2 this device automatically selects the best incoming signal from the field and routes it to the single-most appropriate tower site transmitter. This eliminates the user from having to switch channels to select the closest site. A more complete improvement can be realized by implementing simulcast technology. Used in conjunction with a receiver comparator, simulcast allows all field users to hear all messages if in range of any tower site. Simulcast can completely eliminate over-transmission problems and can provide seamless wide-area communications as required by Patrol. Vehicular radios are equipped with better antennas and transmit with higher power than portable radios,and can sometimes communicate where a portable radio cannot. See Option 2 under Alternatives A and B. It is included Alternative C and D baseline costs. Improvement of the Two-Way Radio Communications System Page 2 Needs Assessment&Conceptual Design Report May 10,2006 Mcpsm"tGULA RKOWNAL Oft"IWAM"Tr4ar MACRO Community Repeater operation is incompatible with receiver comparators and simulcast technologies, in an analog system environment. However, Community Repeater operation can be maintained under these technologies if a digital-type radio system is eventually implemented. This is discussed in more detail later in this report. The loss of Community Repeater operation, without replacing it with an equivalent function, would significantly impact Mountain View Dispatch, as well as field operations as dispatchers and field users would have to sort through every message on the radio channel to determine whether it involves them or not. Regulatory Impacts Recent Federal Communications Commission (FCC) regulatory changes will require the District to make changes to its radio system. Effective January 1, 2011, the District will not be permitted to expand the coverage area of its current system, unless it converts to more spectrally efficient technology. Concurrently, the FCC will prohibit manufacture and importation of equipment not meeting specific spectrum efficiency standards. Furthermore, the FCC has established January 1, 2013 as the mandatory deadline for final conversion to more efficient technology. Thus, the District will not be permitted to operate in its current "legacy" (wideband)mode of operation after this date. Compliance will require the District to either modify its legacy analog equipment to "narrowband" operation (and replace some models that are incapable of such modification), or eventually replace its analog equipment with digital models that are inherently narrowband. Continuing to operate analog equipment has certain limitations, but is the least costly approach. Digital operation eliminates some potential risks associated with converting analog equipment,but is more costly. Conceptual Design Alternatives Macro has provided four Alternatives to meet upcoming regulatory requirements, as well as provide some operational options that target some of the system deficiencies noted in this report. Life-cycle costs quoted below are considered budgetary, 3 and include sales tax, installation, vendor engineering and project management, and a contingency. Costs for any specific options under each Alternative are not included but are presented later in this report. Alternative A —Maintain the Status Quo. This Alternative continues operation of the current technology and includes steps to meet all upcoming regulatory requirements by December 2009. Equipment life- cycle costs are estimated to be$975,000 through 2019. Characteristics of this Alternative include: Continues analog operation(foreseeable future) Community Repeater operation becomes impractical/incompatible as system grows ➢ Additional tower sites needed to offset narrowband coverage impacts r Does not reduce over-transmission problems or enhance wide-area communications Can be upgraded later to support simulcast(see Alternative Q Lowest cost Alternative The time-value of money has not been considered in these estimates. Improvement of the Two-Way Radio Communications System Page 3 Needs Assessment&Conceptual Design Report May 10, 2006 h"OPMAWASMA RMONAL 00 "SPAS DISTR= MACRO Alternative B—Migration to Digital Operation. This Alternative is similar to above, but replaces the legacy 150 MHz analog systems with digital technology by December 2009.4 Most of the District's equipment is incapable of digital operation, so most all equipment would eventually require replacement. Equipment life-cycle costs are estimated to be$989,000 through 2019. Characteristics of this Alternative include: Transitions to digital operation Enhances Community Repeater operation; compatible with all Options Does not suffer from narrowband coverage degradation(compared with narrowband analog) Does not reduce over-transmission problems or provide wide-area communications Can be upgraded later to support analog or digital simulcast(see Alternative C or D) Higher initial costs Alternative C—Analog Simulcast Operation. This Alternative integrates all tower sites together through the use of existing Santa Clara and San Mateo County infrastructure equipment. Allows all radio messages to be automatically transmitted by all tower sites simultaneously. Equipment life-cycle costs are estimated to be$1.743M through 2019. Characteristics of this Alternative include: Continues with analog operation(not upgradeable to digital without considerable cost) Incompatible with Community Repeater operation Suffers from narrowband coverage degradation Eliminates over-transmission problems and provides wide-area communications More complicated network(than Alternative A or B); requires highly skilled technicians/service providers Possibly increases recurring costs due to use of county infrastructure ;o, Higher initial costs(than previous Alternatives) Alternative D — Digital Simulcast Operation. Similar to Alternative C above, but uses digital technology. However, this Alternative provides for Community Repeater operation. Equipment life- cycle costs are estimated to be $1.872M through 2019. Characteristics of this Alternative include: Transitions to digital operation Enhances Community Repeater operation;compatible with all Options Does not suffer from narrowband coverage degradation(compared with narrowband analog) Eliminates over-transmission problems and provides wide-area communications More complicated network(than Alternative A or B); requires highly skilled technicians/service providers Vendors capable of implementing digital simulcast is limited(today) Possibly increases recurring costs due to use of county infrastructure Higher initial costs(than previous Alternatives) 4 Conversion could be delayed as late as January 1,2013. Improvement of the Two-Way Radio Communications System Page 4 Needs Assessment&Conceptual Design Report May 10,2006 N"OPEMINSULA REGIONAL OPEN SPACE 0411IT"My MACRO Enhancements 10ptionsfor Each Alternative The following enhancements and options can be added to each of the Alternatives above(with the noted exceptions). Costs are presented later in this report. Option 1: Implement mobile repeaters to reduce current portable dead spots. This option minimally equips the patrol vehicle fleet(approximately 22 vehicles)with mobile repeaters. Option 2: Purchase and install lower site repeaters to cover dead spots in current and future growth areas. This option installs new tower site repeaters to fill existing coverage "dead spots" in the current jurisdictional areas, and in the future San Mateo County coastal region. Fewer tower site repeaters may be needed if mobile repeaters are implemented under Option 1, or if digital options are chosen. Integrates all repeaters together using a receiver comparator to simplify operation. Option 3: License a frequency pair (second channel) or other alternative for maintenance traffic. This option licenses an additional radio channel to separate Patrol and Maintenance onto separate discreet channels to reduce over-transmission problems and eliminate Community Repeater operation. Recommendations Our recommended actions are listed below in no particular order. Costs are included in the Alternatives listed above,or listed as an Optional cost under a specific Alternative later in this report. Recommendation 1: Consider Implementing Alternative B (Migration to Digital Operation), with a commitment and intent to pursue simulcast technology as described under Alternative C or Alternative D. Digital technology will suffer less of a performance degradation (compared to analog technology) once the District converts to FCC-mandated "narrowband" operation, maintains and enhances Community Repeater operation under various configurations, and will have increasing support from vendors over time. Digital operation can be phased in over time by purchasing digital-capable portable, vehicular and repeater equipment going forward, but operating this equipment in analog mode in the near term (digital radios are capable of analog operation so they will remain compatible with the older radios that are still in operation during the transition to digital). Implementing Alternative B also leaves the District's options open to implementing either type of simulcast technology (analog or digital) in the future, as described in Alternative C or D. Most importantly, simulcast solves the current over-transmission problems, provides wide-area communications, and simplifies system operation. Theoretically, simulcast could be implemented at any time. However, Macro expects the need for simulcast will become even more critical if the District expands its jurisdictional area along the north coast. Such expansion will require additional tower sites, which will further complicate operation and exacerbate wide-area communications problems unless simulcast is implemented. Recommendation 2: Implement mobile repeaters (Option I above). This could reduce the need to construct additional repeater sites to solve some portable radio coverage problems. Consider conducting a"pilot project"by implementing a couple of units to evaluate their performance for possible expansion to more fleet vehicles. Recommendation 3: License an additional channel to provide flexibility (Option 3 above). A secondary frequency pair(channel) could eliminate Community Repeater operation, which would promote certain Alternatives above. Due to a shortage of frequencies in the Bay Area, such efforts are considered long- term (1-3 years). Recommendation 4: Convert radio system to narrowband operation before December 2009. Reprogram or replace equipment incapable of meeting the FCC-mandated narrowband requirement, and switch to Improvement of the Two-Way Radio Communications System Page 5 Needs Assessment&Conceptual Design Report May 10,2006 AVOPENMOULA R6010"AL OP"90^0a Dt$TMCT MACRO narrowband operation before December 2009. This will ensure that compatible replacement equipment remains available. Recommendation 5: Assess and improve antenna systems at some tower sites. Verify whether the Umunhurn tower site antenna system is mounted and operating properly, and consider raising the Sierra Morena antenna higher on tower. Recommendation 6: Perform facility improvements at some tower sites. Electrical grounding, seismic bracing and equipment chassis improvements are recommended at Umunhum, Coyote and Sierra Morena sites. Please see Section 2.4.3 for details. Recommendation 7: Maintain operations on the 150 MHz (VHF) radio band. This radio band provides the most favorable coverage and maintains interoperability with other key agencies, such as CDF, and various Santa Clara County agencies.

EXISTING WIRELESS VOICE SYSTEMS 2.1 Radio System Operation The District operates one radio channel that is shared by maintenance and park rangers (patrol). Users are able to mute messages from the other user group to reduce distractions. However,only one group of users can communicate at any one time since there is only a single channel available. This configuration is referred to as Community Repeater operation. The Mountain View Police and Fire dispatch center in Mountain View dispatch patrol units. Dispatch is able to select among the five different sites on the patrol group, from their console. Field users must advise dispatch of which tower site they are operating on, if different from Black Mtn. Field radios are equipped with up to 43 channels (see Appendix Q. Ten channel positions are used by the District to access one of the five repeater sites (five for the Maintenance group, five for Patrol). However, the user must be trained and have experience to know which repeater best serves the areas they may be in. An eleventh channel exists for communications directly between users in close range of each other (refereed to as the"Tactical"channel). Users indicated that lack of coverage was their greatest concern. Section 2.5 lists the top four areas where users desire improvement. From inspection of the coverage prediction maps provided in Appendix B, and discussion with users, the Black Mtn. site can be heard in a majority of the Preserves. The remaining sites tend to fill gaps in Black Mtn.'s coverage footprint. Thus, users tend operate on the Black Mtn. channel most often. Macro notes that users seem to understand the operation of the radio system well and are used to switching among radio sites as they travel. The fact that Black Mtn. covers large portions of the area lessens the operational impact of manual site selection. Dispatch cannot hear or communicate on the Maintenance channel. Macro is aware that dispatch can unknowingly interfere and block Maintenance messages on occasion. The blocking' problem is the second most critical deficiency noted by users. This is where one user is unaware of an ongoing conversation on the channel and inadvertently makes a call,blocking one or both messages. In some cases, neither the blocked user nor the initiator is unaware that their message has been blocked. Users reported that both Maintenance and Patrol could block or cover each other's messages, particularly if a user is unfamiliar with the radio system or has not been trained to unmute their radio before transmitting to make sure the channel is clear. They also noted that even users in the same group (Patrol or Maintenance) could block each other's message since they cannot always hear another user who may be operating on a remote repeater(usually other than Black Mtn.). This deficiency is a safety concern to Patrol. As the system grows in size, and use increases, this problem is expected to worsen. This is caused primarily by Community Repeater operation. The inability of users to hear messages routed through remote tower sites further contributes to this problem. Separating users on different radio channels partially solves this problem. Implementing a Simulcast type radio system in addition to separate radios channels will eliminate this problem entirely. 5 It is also known as"talk-over",or an over-transmission. Improvement of the Two-Way Radio Communications System Page 7 Needs Assessment&Conceptual Design Report May 10, 2006 h"OPRM0184"RIOMM"OftN SPACR WSTFACT MACRO There are less costly approaches, but most are less effective. However, simulcast adds significant complexity to the radio system, and can increase recurring costs to a significant degree. These are discussed later in this report. 2.2 Interoperability with Outside Agencies Patrol communicate regularly with the following outside agencies(in order of greatest occurrence): Santa Clara County Parks Santa Clara County Fire California Department of Forestry (CDF) Palo Alto Fire Department Such communication is usually accomplished by a patrol unit switching to the other agency's radio channel, or a common channel such as CALCORD, as opposed to these agencies switch to the District's channel. However the latter is technically possible if the other agency has the District's channel programmed into their radio equipment. Patrol desires to have the capability communicate with the Santa Clara County Sheriffs Department. However, the District's vehicular radios are incompatible with the Sheriffs digita16 radio system. It is unclear if the Sheriff would permit the District to access the system, however. 2.3 Equipment Inventory and FCC Licenses The following information was derived from inventory lists and site surveys.

However, it is well known that law enforcement radio equipment experiences the heaviest use of most systems, which can reduce its useful life to less than that shown. The table below shows all District licenses considered in the current project. 6 This system may conform to Project 25 digital radio standards.

Macro was unable to identify the antenna associated with this station. In order to communicate with a field a Ranger, Mountain View Dispatch must manually select the radio tower site it believes is closest to the field unit it wishes to communicate with. Of course, this is not always possible, so the dispatcher typically selects and calls first from Black Mtn., and if no response is heard, they must proceed through the remaining four sites. From Macro's experience, it is unusual that a busy dispatcher will try all the different tower sites; they will usually try the most likely one, and if no response is heard, drop the call altogether, or hope that the unit calls back in and identifies which site they are using. This is a significant drawback, and is the result of using stand-alone (non-networked) repeater tower sites. If the field unit is not in range of the site the dispatcher is calling on, they will never receive the message. While mobile repeaters can slightly improve this situation, deploying a simulcast-type system would likely eliminate this problem. 2.4.2 Future Dispatch Facilities Today, Mountain View Dispatch connects to the radio system over-the-air via a base/control station radio — similar to how a field user connects to the radio system. Fortunately, we understand that the dispatch center is located in an ideal spot to be able to receive signals from all five stand-alone repeater tower sites. However, if the District contracts with an agency at a different location in the future,which many not be ideally located with respect to reception of the tower sites, the base/control radio could be located elsewhere, and connected to the dispatch consoles via microwave radio (preferred), or through leased analog or digital lines. In fact, the base/control station radio could remain at the Mountain View Dispatch Center, and remotely connected to consoles elsewhere. However, we were unable to identify any microwave radio links that exist at the dispatch center today. Thus, telephone or digital lines may be required to establish a connection. These have annual recurring costs of$1,800 to$5,400. Improvement of the Two-Way Radio Communications System Page 9 Needs Assessment&Conceptual Design Report May 10,2006 hDOMMMASULA RG010KAL OVIN SPACE 0%TV"CT MACRO As systems grow, agencies normally establish a direct connection to the radio network via microwave radio. However, the five repeater tower sites are not connected together or to a central point today, precluding this option. However, Option 2 of either Alternative presented later in this report would create such a network, which would be an avenue for such a connection. In conclusion, Macro suggests that the selection of dispatch centers and radio networks do not have to depend on each other. 2.4.3 Prerequisite Site Improvements Macro surveyed the District's radio facilities to identify any deficiencies or problems that would preclude their reuse with any new system. The following general list of site improvements are recommended by Macro. Budgetary costs for these improvements are provided later in this report. Mt.Uniunhum(Tomita Hill) Coyote Peak(Santa Teresa) Improve equipment electrical grounding Improve equipment electrical grounding Install equipment moisture-proof cabinet Seismically brace equipment cabinet Install cabinet ventilation(passive fans) Troubleshoot antenna system Possible antenna replacement Sierra Morena(Skaggs Point) Raise antenna above foliage obstructions Repair grounding on lightning arrestor Verify if crystal filter is necessary 2.5 Wireless Coverage Assessment Reliable vehicular and portable radio coverage is required in all preserves, and roads and trails linking these areas. However, given the terrain in these areas and the physical limitations of wireless signals, it will not be possible to cover all areas to a high-reliability in a reasonably economic way, particularly to support portable radios. The current selection of tower sites and the propagation characteristics of the current 150 MHz radio frequency band remain the best approach to cover the greatest area for a reasonable cost. By inspection of the maps in Appendix B, it is clear that vehicular radio coverage is much more complete than portable coverage. In most cases, entirely new repeater sites will be needed to provide highly reliable portable coverage in some of the problem areas. Overall, the these additional repeater sites will simply fill small, hard-to- cover gaps, and will account for a very small percentage of the total jurisdictional area of the District. Small, low-cost radio repeaters are available,and can be mounted on existing buildings. However, from an operational perspective, unless this repeater is somehow integrated into the larger network, it will not serve much of a purpose. Integration requires an interconnection link back to one of the other sites, and overall integration of the five existing sites—all of which are stand-alone today. The user in the field must manually select which site to use; adding a new repeater will further complicate system operation from a users perspective. We have addressed this integration issue as an option to the various Alternative systems described later in this report. Improvement of the Two-Way Radio Communications System Page 10 Needs Assessment&Conceptual Design Report May 10,2006 600PIEN04SU"RONO"L OP"IWACE MWOM MACRO Table 3 below lists poor coverage areas as reported by users. These areas are also shown on the coverage prediction maps in Appendix B. The prioritization indicates the order in which mitigation should be approached, considering the degree of the problem, number of calls for service and overall importance of the area as suggested by users. Table 3—Re orted Coverage Problem Areas Mitigation Type of Priority Description of Area Equipment Macro Assessment 1 Western portions of: Portable Comment:Macro could not verify poor portable Purisima Creek Redwoods coverage in northwest areas near Purisima. E.C.de Madera Creek Purisima site should cover northern and some Redwoods southern portions of E.C.de Madera Creek Redwoods;users may be experiencing limitation of"multisite"system design. Macro verified poor portable coverage in southwest portions of E.C.de Madera Creek Redwoods due to terrain and foliage losses affecting Sierra Morena's signal strength. Efforts to predict effect of raising the Sierra Morena antenna showed improved coverage,but not to extent needed to provide highly reliable portable coverage. Suggestion: An additional tower site would be needed in E.C.de Madera Creek Redwoods to provide reliable portable coverage. Use of Mobile Repeaters could reduce issues significantly. Our Option 2 of either Alternative will improve problems,to a lesser degree. At a minimum,consider raising the Sierra Morena antenna to the highest western spot on the tower to help reduce terrain and foliage attenuation effects. Also,have technician verify if existing filter equipment we found here is needed, remove if unnecessary to curb any additional signal attenuation. 2 Bear Creek Redwoods Portable Comment: Verified poor portable coverage; (west of Lexington Reservoir) Vehicular vehicular coverage should be adequate. Umunhum should be primary serving site, following closely by the Black Mtn.site. Suggestion: An additional tower site would be needed here to provide reliable portable coverage. Use of Mobile Repeaters would also be significant.In any case,have a technician identify and inspect the Umunhum antenna (Macro was unable to)to verify it is physically located to best serve this area;replace antenna if aged,even if it tests fine. Perform a receiver desensitization test to verify proper receiver operation.

Our predictions hold even if the Umunhum antenna is working properly. Suggestion: Mobile Repeaters would help in some areas. More study needed to determine cause of the coverage problem. Consider simulating relocation of the Umunhum repeater to a different site in the same area to see if it would improve coverage here,without worsening it in other areas. 4 Picchetti Ranch Portable Comment: Verified poor portable coverage. Umunhum should be primary serving site, following closely by the Black Mtn.site. Suggestion: An additional tower site would be required for reliable portable radio coverage. Mobile Repeaters would also be a benefit here. In any case,perform Umunhum efforts noted above for Area 2. We note that use of Mobile Repeaters' devices that relay portable radio message through a users vehicular radio - appear to be an obvious choice to improve many of the portable radio coverage problems. This is because Macro found that many of the areas above seem to have reliable vehicular radio coverage, and if portable radios could be linked to the network through the vehicular radio, communications range would effectively be improved. Such packages can cost $1500 to $2200 per vehicle,not including the vehicular or portable radio they would interface with. However, Macro notes that there are numerous operational limitations that users must he tolerant of These include the inability to remotely change the channel of the vehicular radio from the portable (on some repeater models), the limits on distance between the user and vehicle, and occasional voice message truncation at the beginning of transmissions. Most packages are partially customized to the type of vehicular radio model in use, complicating purchases and change-outs of replacement radios. Ongoing user training is also necessary. However, the majority of agencies that deploy them have been satisfied with their operation. EBRPD and the CHP are currently using such devices. We would recommend a representative pilot or trial project be conducted with one or two of the units before purchasing them for a large number of vehicles. Some of these limitations could be addressed if the District implements Option 2 (Simplify System Operation)under either Alternative discussed later in this report. However, we note that if cost was not a limitation, further enhancement the fixed infrastructure, to enhance coverage and simplify operation, usually remains a preferred approach. This provides the most significant benefits, both in performance and dependability, as well as operational simplicity. However, See Glossary for a definition. Improvement of the Two-Way Radio Communications System Page 12 Needs Assessment&Conceptual Design Report May 10, 2006 MACRO from our experience, given the severity of the District's terrain, filling even a few of the coverage holes can be a costly undertaking. 2.5.1 Future Changes in Jurisdictional Area The District may be taking responsibility for the following additional areas over the next five years: Growth Area I -Coastal area from Montara to approximately Pigeon Point,west of highway 35 Growth Area 2- Smaller fill-in areas(Sierra Azul),due west of Mt. Umunhum With regard to Growth Area 1, the best serving site depends on a users location (see Appendix B, Map 3, which shows which tower site would be strongest in each area). However,this map does not indicate whether and area is adequately covered. Please refer to the other maps for this information. It is clear that some of these areas may have vehicular coverage. Portable coverage is expected to be extremely poor to non-existent. Almost all areas will require the use of Mobile Repeaters, or additional tower site repeaters. With regard to Growth Area 2, Mt. Umunhum, and secondarily Black Mtn. are the most likely sites to serve this area. Vehicular coverage is marginal here, and reliable portable radio coverage is virtually non-existent. 2.5.2 Radio Coverage Predictions for Existing and Future Systems Appendix B contains coverage maps that illustrate the difference between the naffowband and legacy operation, as well as coverage from specific sites. These maps are listed below. Table 4—Coverage Prediction Maps Channel Prediction Maps MROSD Ranger(all sites) Map IA- Existing System-Talk-In MROSD Maintenance(all sites) Map I B- Narrowband Analog System-Talk-In Map 2A- Existing-Umunhum Talk-in Map 213- Narrowband Analog-Umunhum Talk-in Map 3- Strongest(Most Likely)Serving Site Map IA should roughly illustrate the extent of coverage provided by the existing 150 MHz system, for a specific level of reliability. This would also be representative of coverage from a digital-type radio system. The Narrowband Analog maps illustrate the coverage provided by the same radio system, but operated in narrowband analog mode(such as if the District converts its existing system to narrow). We have provided maps of coverage from the Umunhum site, in both modes, to indicate the specific areas this site should be covering. Map 3 (Strongest [Most Likely] Server) is intended to show areas where the particular site's signals are stronger than all others. Each site is assigned a different color to show where each dominates. However, presence of a color is not indicative of adequate coverage. It only indicates that a particular site is better than others in reaching the area. A description of our methodology and assumptions used to develop these maps is fully described in the Appendix. While users may seem to experience reasonably clear signals in areas shown as poor on these maps, the signal they hear may not be strong and/or clear enough to meet the stringent reliability and voice quality goal Macro use in its predictions. We have chosen to calibrate all maps using a Improvement of the Two-Way Radio Communications System Page 13 Needs Assessment&Conceptual Design Report May 10,2006 YA"OPKHMSM-A MOWN"oftM SPACE Dt*TR= MACRO -4->>- reliability margin of 95%and a Delivered Audio Quality (DAQ)value of 3.4.8 Thus, all coverage maps show where there would be a 95%chance of hearing an extremely clear radio signal. 2.5.3 Overall Coverage Assessment In looking at the Map 3 (Strongest [Most Likely] Server), it is clear that Black Mtn. is the District's single most important site. We also note that Coyote's contribution is somewhat limited. One possible action that could be taken is to relocate the Coyote repeater and antenna to a site that can fill some gaps in Area 3 or Area 2. However, Dispatch may lose the ability to communicate with this repeater without changes at the dispatch center. The Umunhurn antenna system should also be assessed before any changes are made to Coyote. Our analysis showed that terrain obstructions just west of Sierra Morena blocks signals to reported coverage Area 1. There is a possibility that raising the antenna to the highest point possible on the tower could reduce the impact of this obstruction, and reduce the signal attenuation from foliage. We also note that some filtering equipment exists that might be contributing to some attenuation as well. Considering all of these factors may make a difference west of the site. 2.6 Interconnect Systems The District does not currently use microwave radio links or ]eased telephone lines to integrate its communications system together or to the dispatch center. 8 III Defined as"Speech understandable with repetition only rarely required.

REGULATORY CONSIDERATIONS The Section addresses any significant Federal Communications Commission (FCC) legislation affecting the project. 3.1 PR Docket 92-235"Refarming" In June 1995, the Federal Communications Commission (FCC) adopted PR Docket 92-235, known as the "Refarming" plan. The Commission later clarified and adopted additional rules in this Docket in February 1997. The intent of the plan was to increase the number of radio channels available within particular radio bands by promoting more spectrally efficient use. Major rule modifications were adopted which govern public and private agencies' use of radio channels in the 150 and 400 MHz bands. The ruling had no effect on radio bands above 512 MHz. Some of the more important changes included(1)narrowing the width of each existing channel, thereby creating new channels in between, and (2) reducing radiated transmitter power of high-elevation base and repeater stations such that channels could be reused in other surrounding areas, and (3) permitting trunked-type systems. These aspects affect radio system range and available throughput for both voice and data systems employed on these radio bands. These rule changes have an impact on the District's existing system, and will affect the design of any new system. These changes would take place in two steps. The first step would: 0 Require the use of narrowband-capable (12.5 kHz or less) equipment on all newly-created channel (existing channels are 25 and 12.5 kHz today) 0 Permit trunking on the 150 MHz and 400 MHz radio bands 9 Immediately require applicants for new systems or channels to comply with new radiated power requirements(applied to narrowband and wideband channels) • Grandfathered all existing licensees' radiated transmitter power • Consolidate the 20 existing radio services into two(Public Safety and Business/Industrial) • Require manufacturers of new products to meet a minimum spectral efficiency of one voice channel per 12.5 kHz of bandwidth, and 4,800 bits per second(bps)per 6.25 kHz channel • Elimination of Inter-service Sharing (use of business frequencies by public-safety, and vice versa) While the new rules permitted used of trunked-type systems on these frequency bands, the Commission also established very stringent requirements for trunked applicants to protect existing, non-trunked licensees from potential interference that could result. These requirements make it difficult, but not impossible to implement a trunked-type radio system in these radio bands. These changes will have the following effect on new systems: • Increase costs of new equipment in the near term • Reduce the range or coverage of the base station and mobile radios • Potentially double the number of channels in each band in the long term (10-20 years) Improvement of the Two-Way Radio Communications System Page 15 Needs Assessment&Conceptual Design Report May 10,2006 M"X"KNO"""Pleow"AL Op"$PAC*ots""= MACRO The second step of this ruling would have required new radio products manufactured after January 2005 to meet a minimum spectral efficiency standard of one voice channel per 6.25 kHz of bandwidth. However, the effective date of this order was stayed in 200410 due to concerns from licensees and manufacturers. 3.2 FCC Narrowbanding Rule(WT Docket 99-87) To accelerate the Refarming process, the FCC later adopted the Third Memorandum Opinion and Order, Third Further Notice of Proposed Rule Making and Order in WT Docket 99-87 (December 20, 2004), which set hard dates affecting the importation, manufacture and operation of equipment affected by the new spectrum efficiency standards. The following key transition dates were specified for Public Safety licensees: January 1, 2011: (a)Denies applications for new licenses,or modifications to existing licenses that request expansion of existing service coverage,which do not meet specific spectrum efficiency standards;and (b)Prohibits manufacture and importation of equipment not meeting specific spectrum efficiency standards. January 1,2013: Deadline for use of equipment meeting specific spectrum efficiency standards. The upcoming spectrum efficiency standard is a minimum of one channel per 12.5 kHz of bandwidth for systems conveying voice messages." Today, the District's voice radio system operates on 25 kHz of bandwidth but only provides for one voice message channel, half as much as the upcoming efficiency standard requires.12 Therefore, unless the District makes changes to its system efficiency, it will not be able to expand its current coverage area - by adding or changing tower sites - after January 1, 2011, and could not continue operating its system in its current configuration after January 1, 2013. Additionally,after January 1, 2011,the availability of such legacy equipment will quickly diminish until domestic inventories are depleted. Macro anticipates that many agencies may attempt to replace portions of their aging legacy networks after this date, only to find that their new, more efficient equipment is incompatible with the rest of their legacy network. The agency must therefore wait to deploy its new equipment, or, immediately reprogram, modify or replace (possibly prematurely) the remaining legacy portions of their networks. 9 Applies only to new products that require FCC certification. Existing 25 kHz equipment models could continue to be manufactured,however. '0 Third Memorandum Opinion and Order,Third Further Notice of Proposed Rule Making and Order,WT Docket 99-87,FCC 04-292,adopted December 20,2004 " Or two channels per 25 kHz of bandwidth for systems conveying voice messages. If the radio system is to support data messaging,it must convey 4,800 bits per second(bps)per 6.25 kHz of channel bandwidth,or equivalent,up to a maximum of 25 kHz. 12 This is often(and confusingly)referred to as"wideband"operation. This report uses the term"current configuration"to refer to the technology now in use by the District. Improvement of the Two-Way Radio Communications System Page 16 Needs Assessment&Conceptual Design Report May 10,2006 SPAM MACRO 3.3 Compliance with the New Efficiency Standards The new efficiency standards could be met by either(a) doubling the capacity of the radio system (e.g., enable two or more voice messages to be conveyed on the current 25 kHz-wide channel)', or by (b) halving the amount of channel bandwidth the current system is using. The vast majority of FCC licensees, which includes the District, can only take the latter action (halving its bandwidth, or"narrowbanding") due to unavailability of high-efficiency wideband equipment in the 150 MHz radio band. This is unfortunate,as once a licensee converts to a narrower bandwidth,they are effectively giving up valuable radio spectrum, which could have been used to obtain greater system capacity(i.e., more radio channels, in effect). This occurs because licensees who convert to narrowband operation must modify their FCC licenses to reflect the narrower bandwidth, which will signal others looking for spectrum to move onto the"green space"created adjacent to the narrowed channel.14 However, Macro is aware of technology that will provide two voice channels on a single narrow radio channel being manufactured for the 700 MHz and 800 MHz radios bands, which will be shipping in 2008. Additionally, equipment that can provide four voice channels in a single 25 kHz channel—which would be ideal—is already shipping in 700 and 800 MHz bands. However, we are aware of no plans to produce such equipment on radio bands below 700 MHz. We also note that all of these systems are digital-type trunked radio systems and are considered proprietary. Thus, only one manufacturer produces compatible hardware, which would lock a customer into a single, and possibly expensive, source. Therefore,conversion to narrowband is the only logical choice at this time. The District can accomplish this in two ways. It can choose to narrowband its existing (analog) equipment, or affect a complete replacement to a new narrowband digital radio system. These options are further discussed in Section 4. l 3.4 When to Comply with the New Efficiency Standards A key question is when the District should plan to convert to narrowband operation. The District could continue operating its legacy equipment until January 1', 2013, if all the following can be attained: Sufficient spare parts can be maintained or obtained for its legacy infrastructure and fleet; and Y Enough spare legacy vehicular and portable radios are in place on or before January 1,2011 to support any anticipated fleet growth through January 1,2013; and No coverage expansion is planned after January 1',2011,through addition of new repeaters and/or tower sites using its existing 150 MHz radio channel. However, to maintain flexibility and to reduce the chances of a service disruption, Macro recommends conversion to narrowband operation before January 1, 2011. How far in advance of this date should the conversion take place depend upon when manufacturers stop producing such legacy equipment, particularly in models that the District may want or require. 13 There is a widely held belief that all licensees must convert to narrowband(12.5 kHz)operation in 2013;this is false. The rules explicitly permit wideband(25 kHz)operation after 2013,as long as it meets the required efficiency standard. 14 There is no interference concern since the new neighbor must ensure no interference occurs,as is the case today with wideband channels. Improvement of the Two-Way Radio Communications System Page 17 Needs Assessment&Conceptual Design Report May 10, 2006 I LUDP*MaWA R4040kAL OMN SPA.M M"Wr MACRO Therefore, it might be prudent to consider conversion to narrowband operation as late as December 2009. We see no other advantage to an earlier conversion. Deferring this conversion may turn out to be an advantage, given that one or more manufacturers might introduce equipment that is both compliant with the 2013 efficiency standards, and is capable of operating on the District's current 25 kHz bandwidth channel. 3.5 Impacts of a Narrowband Conversion The District current operates analog-type radio equipment. Converting analog equipment to narrowband operation can worsen coverage, particularly in areas where weak signals exist today (fringe areas). Furthermore, if the District is experiencing certain types of interference today, such as interference from another agency that may be using the same radio channel, its effects will become significantly more disruptive and have a greater impact than they have today. We are not aware of any current interference problems, although there have been some in the past. Much of these coverage and interference impacts can be overcome by the addition of tower (repeater) sites. Basically, by ensuring that the District's signals are stronger in areas it operates, fringe area problems will be reduced, and many interference problems can be effectively "covered". Such an approach may be practical and effective, and could be lower cost than most other options, depending on how many new tower sites would be required. "Before and after" coverage prediction maps are provided in Appendix B. These show predicted differences in coverage between the District's existing legacy systems, and that of an analog narrowband system. The effects of interference cannot be predicted and are not shown, but will effectively worsen coverage in some areas unless tower sites are added where needed. Another approach is to convert to a digital radio system, such as a Project 25-compliant type, or other more proprietary types. In general, Project 25 type systems provide similar coverage to the District's legacy system, and are much less affected by the type of interference noted above. However, capital costs are higher,although the recurring costs can be similar to that of analog types,if not slightly higher. The District can expect greater manufacturer support for digital products as time goes by, and much less for analog products. Macro does believes that most all radio systems will eventually convert to digital operation over the next six to ten years. If the District is content with the predicted coverage area of the narrowband analog system (see Appendix B, Map I B), and no interference exists today,15 converting its analog equipment to narrowband is a valid option. If the number of marginal areas is minimal, and those that do exist can be solved by the addition of a single tower site,this choice remains valid. Otherwise,a digital-type system could be considered. 3.6 Converting to Narrowband Analog Operation All radios using a particular radio network should operate in the same mode —mixing narrowband and legacy equipment on the same radio channel would result in some voice quality degradation and miscommunication,under certain conditions. This degradation will only occur during reception of some legacy signals by fleet or repeater equipment already configured for narrowband operation. This degradation will not occur in the opposite case, such as when equipment configured for legacy operation is receiving signals from other narrowband fleet '5 There is no reason to believe that interference would increase over time. Improvement of the Two-Way Radio Communications System Page 18 Needs Assessment&Conceptual Design Report May 10, 2006 "` WACE 04SITOCT MACRO radios or tower site repeaters.16 Thus, any conversion plan should focus on minimizing the duration of the former condition when possible, as well as insuring that the dispatch center will not miss inbound emergency calls from field units. In anticipation of narrowband conversion, we understand that the District began purchasing narrowband capable fleet and repeater equipment a number of years ago, as equipment required replacement due to age or condition. Thus, some of the District's fixed infrastructure (repeaters) can be reprogrammed or modified to operate on a narrower channel bandwidth. Vehicular and portable radios must be narrowband-capable, on a per-channel position basis, or be replaced with models that are capable of this. Table 5 below indicates the narrowband capability of the District's equipment.

"Hardware Modification" indicates that some parts need replacement to enable narrowband. The remaining equipment can neither be programmed nor modified to support narrowbanding. i Narrowband conversion is straightforward. The following steps are required. In preparation for conversion: Step I: Order narrowband retrofit parts for older repeater stations that will be retained after conversion (perform as soon as possible)" Step 2: Install any new tower sites, if required per this report; new sites can be configured for narrowband mode initially Exception: If new tower site(s) will be implemented well before the narrowband conversion, i.e., to fill current coverage gaps in the legacy system, initially configure them for legacy operation, and reprogram all vehicular and portable radios (the "fleet") for the new tower site channel(s). Consider programming the fleet with a second set of channels, but set for narrowband mode, to reduce or eliminate a second reprogramming later; Step 3: Replace any fleet or repeater equipment incapable of narrowband operation or conversion re i However,such signal will be lower in volume than other legacy signals. This is only considered a nuisance, and should not cause significant operational problems. 1� Applies t repeaters that require retrofit parts and/or retuning,as opposed to simply being reprogrammed(see Table 5 in the previous Section). In this case,Macro recommends ordering retrofit parts now to assure their availability when needed. If the equipment is approach the end of its useful life,Macro recommends replacement.

Step I of the narrowband conversion may not be necessary; this can be established once more conversion experience is gained by the industry over the next few years. 3.7 Converting to Narrowband Digital Operation As noted earlier, conversion to digital operation, particularly Project 25, would meet the 2013 spectrum efficiency requirement since it is a narrowband technology. However, with the exception of the Mountain View Dispatch radio equipment, none of the Districts other equipment is capable, or can be modified for digital operation. Thus, all user equipment and remaining fixed repeater and base station equipment must be replaced with digital-capable models before conversion to digital operation is planned. The District is not in an unusual position as over 90 percent of government agencies operate analog-only equipment. Most all agencies will be facing a similar challenge over the next few years. If the District is planning to covert to digital, it can begin to purchase digital user and fixed equipment today. Since the vast majority of these models are backward compatible with both the legacy analog operation, as well as narrowband analog operation, these models will operate on the current legacy system as well. This fact also permits these radios to operate on the other external radio systems, such as with CDF, for the long term. There are several drawbacks to digital conversion. These are: ➢ Higher equipment(capital)costs(although we expect costs to drop over time) ➢ Outside agency incompatibility Outside agencies having analog-only radios will not be able to monitor or communicate on the District's radio system this will lessen over time). However, Macro understands that the District's field units more often switch to the outside agency's system, as opposed to those outside agencies switching to the District's system. Thus,digital migration would not significantly impact such communications. While conversion to digital conversion could be deferred until January 1, 2013, for the reasons cited in Section 3.4 above, it may be less disruptive to covert by December 2009, otherwise the District may "Other outside agencies have the District's legacy channel programmed into their fleet;these fleets will require that the District channel be reprogrammed to narrowband operation as well. 19 This step has radio technician reduce transmitter"deviation"to a level consistent with narrowband levels.

However, this remains an option. For the purpose of this report,we have assumed that a digital conversion could occur in December 2009. i Improvement of the Two-Way Radio Communications System Page 21 Needs Assessment&Conceptual Design Report May 10, 2006 A900MAL OP"*P^CK My"f= MACRO SECTION 4. CONCEPTUAL DESIGN ALTERNATIVES AND COSTS Macro has provided four Alternatives for consideration. Each alternative includes Options that are targeted at addressing some of the systems deficiencies noted earlier in this report. The initial cost tables under each Alternative represent complete system replacement. For a more complete picture,we have provided a second table in each section that provides life-cycle costs through the year 2019. Equipment replacement schedules are based on Table I in Section 2.3, which lists the useful life for various types of hardware. Each Alternative is based on the following assumptions and considerations unless otherwise noted: • 150 MHz frequency band • Meet anticipated FCC spectrum efficiency requirements • Use of similar-quality tier fixed and user equipment as is use today • Utilize the same tower sites as in use today • Equipment quantities based on current inventory(includes spares) • Assumes new antennas at all sites • New systems are furnished and installed by a single vendor • Dispatch workstations(computer)is supplied by others • No backup battery systems are provided at tower sites(none exist today; only generators) Costs include sales tax, installation, vendor engineering and project management, and a contingency. Costs for professional (consulting) efforts, such as vendor proposal review and vendor oversight/project management are shown as a line item and are optional. The most significant cost factor will be the tier and feature set of the vehicular and portable radios. Cost estimates are considered conservative, and could be reduced if lower-tier equipment is procured, or multiple RFP's are used to procure different subsystems. Basic coverage provided by each of the Alternatives, without Optional Systems/Enhancements, are shown in the Appendix.

Equipment incapable of narrowband operation would be replaced with new narrowband-capable analog equipment by this date, and the entire system is transitioned from legacy(wideband)operation to narrowband. Some user equipment is overdue for replacement now, so we have assumed that this equipment would be replaced in the near term with narrowband-capable analog models. Selecting this Alternative would not preclude the District from later upgrading to simulcast(Alternative C). However,care be taken to ensure simulcast-capable repeaters are selected. Macro also recommends that all repeaters - including those that may be needed in the future - be purchased at the same time to ensure consistent and matched performance. The following arguments relate to this Alternative(without the Options/Enhancements below). PRO ➢ Maximizes reuse of existing fixed and user equipment Many brands and tiers of user equipment expected to be available through 2009 No has significant impact on interoperability Open standards-based analog operation promotes interoperability Simple to maintain;allows for competitive outside maintenance contracts Least costly(then other replacement Alternatives) CON Reduction in coverage in current fringe areas Vendor support for analog products will diminish after 2009 New equipment models and options will diminish after 2009 Radios cannot operate on any outside agency systems which are/or convert to,digital ➢ Cannot support individual-calling,messaging or other advanced features Narrowband analog is more susceptible to co-channel interference'o Budgetary costs are shown below. Costs are for all new equipment, and do not anticipate reuse of any existing eguipment. Estimated costs to mitigate reductions in radio coverage following conversion to narrowband operation are included. We have assumed that two new tower sites may be necessary, and that one or more of the existing tower sites could require relocation to optimize radio coverage. Additional analysis would be required to establish a more accurate estimate. 20 We note that no interference exists today,and we cannot anticipate any in the future.

None of the District's user equipment, and most of its fixed equipment is capable of,or modifiable for,digital operation. Thus, all equipment must eventually be replaced.21 To minimize disruptions, we have assumed that conversion to digital would occur on or before December 2009, although such conversion could be delayed as late as January 1,2013 if desired. Replacement equipment is assumed to be Project 25 Phase 122 compliant, but could be any manufacturers digitally compliant equipment. Community Repeater operation is a standard feature of Project 25 digital systems, so this functionality could continue, and would be enhanced. Our research indicates that Project 25 radios can help prevent over-transmission in some cases, as well as provides all-call and possibly individual (radio-to-radio, selective)call functions.Caller-ID is a standard feature as well. This Alternative does not have a significant impact on the interface between the dispatch consoles (provided by others) and the associated base/control station radio, as the interface remains analog. Thus,this radio system could be interfaced with any typical dispatch console workstations system. Selecting this Alternative would not preclude the District from later upgrading to simulcast(Alternative D). Please see the equipment restrictions described for Alternative A. The following arguments relate to this Alternative(without the Options/Enhancements below). PRO Coverage generally equivalent to current legacy system Vendor support for digital products increasing Latest equipment models will likely be digital Digital radios are backward compatible with legacy and narrow analog systems :i-, Enhances Community Repeater functionality(can reduce some over-transmissions) Provides individual-calling, messaging and other advanced features Project 25 is an open standards-based technology CON Requires replacement of some existing legacy equipment before the end of its useful life Outside agencies incapable of digital could not communicate on District's system Fewer equipment models available today(temporary situation) Some outside maintenance shops are not yet trained on digital(reduces pool of shops) More costly than analog 2' The exception is the Districts Base/Control Station radio that supports the Dispatch Center.

Improvement of the Two-Way Radio Communications System Page 26 Needs Assessment&Conceptual Design Report May 10,2006 ANDPV99MMA MACRO We note that one main reason that the cost of digital radios are higher is that fact that manufacturers only provide digital on their high-tier (most expensive) models initially, and only later focus on more affordable products as competition grows. We expect prices on digital conventional products to fall over the next five years. However, we have assumed that current price levels remain constant in our budgetary estimates.

Under simulcast, every radio message would be broadcast from each tower site simultaneously; instead of just one site as is done today, providing wide-area communications. Simulcast inherently alerts all field staff when the radio channel is already in use,effectively eliminating the chance that two or more messages will conflict with each other This would require the District to lease a small amount of capacity on existing Santa Clara and San Mateo County microwave radio backhaul links, and find equipment rack space at a central location (I rack). Some new low-capacity backhaul links would be required. Simulcast on analog systems cannot support Community Repeater operation. Thus, either both user groups must utilize a common channel or code, or a second channel must be licensed. The latter is listed as Option 3 in this report.

This will require licensing of an additional low power radio frequency. Use with a digital radio system should be investigated but should be possible. Option 2:Add repeaters to cover dead spots in current and future growth areas(6 repeaters) This option installs repeater near locations having poor vehicular coverage today, and provides for repeaters to cover the San Mateo coastal areas where the District may have responsibility in the future. Costs include repeaters for one radio channel. It assumes that existing county or other commercial communications site is utilized that is already equipped with an equipment shelter and antenna tower. Identifying specific sites at this time is beyond the scope of this project. For analog Alternatives, three sites are assumed to support coverage problems in the existing jurisdictional area, with three being added over time in the northern coastal areas. For digital Alternatives, we assume three sites would be needed in the existing area, and two along the coastal area. The difference in number of sites is due to coverage degradation we expect with narrowband analog operation. Under simulcast Alternatives we assume that all sites are simulcast consistent with the specific Alternative. The use of Mobile Repeaters may reduce the number of sites needed in the existing jurisdictional area. One significant aspect of this Option, when used with Alternative A or B, is that it integrates or networks all existing and planned District repeater sites together using a receiver comparator, existing Santa Clara and San Mateo county microwave radio backhaul links, and some new microwave radio links. This could reduce the number of channel positions needed on field radios to one or two, significantly simplifying system operation. As such,this Option is seen as a significant upgrade to these Alternatives,not just a small incremental change. With Alternative C or D, integration or networking is performed as part of the baseline Alternative to begin with. This Option simply installs additional repeaters, and networks these into the previously established network. Thus,these costs are purely incremental. Option 3:Add a frequency pair(secondch.)to separate Maintenance and Patrol This Option would reduce over-transmission problems, and provide full channel priority to each user group (the District's channel is shared by Maintenance and Patrol today). Under this Option, the District licenses a second frequency pair (channel), and places Maintenance on the new channel. A second repeater and associated antenna system would be installed at each site to support the new channel, and all user equipment would be reprogrammed with the new channel. Community Repeater operation would no longer be needed or necessary. Licensing and basic regulatory engineering costs are included. This Option does not include site lease costs would likely increase since the District would effectively be doubling the amount of equipment at each site. Any new channel must operate under FCC Refarming guidelines. Thus, additional transmitter sites may be required to offset coverage impacts resulting from lower permissible radio transmitter power, as well as the anticipated coverage impacts of narrowband operation. Costs for these impacts cannot be anticipated at this time and are not included.

RECOMMENDATIONS Our recommended actions are listed below and are presented in no particular order. Costs for these recommendations, if any, are included as part of particular Alternatives or associated Options above. Recommendation 1: Consider Implementing Alternative B (Migration to Digital Operation), with a commitment and intent to pursue simulcast technology as described under Alternative C or Alternative D. Digital technology will suffer less of a performance degradation (compared to analog technology) once the District converts to FCC-mandated "narrowband" operation, maintains and enhances Community Repeater operation under various configurations, and will have increasing support from vendors over time. Digital operation can be phased in over time by purchasing digital-capable portable, vehicular and repeater equipment going forward, but operating this equipment in analog mode in the near term (digital radios are capable of analog operation so they will remain compatible with the older radios that are still in operation during the transition to digital). Digital radios are more costly than analog types,but costs are expected to drop over time. Implementing Alternative B also leaves the District's options open to implementing either type of simulcast technology (analog or digital) in the future, as described in Alternative C or D. Most importantly, simulcast solves the current over-transmission problems, provides wide-area communications, and will simplify system operation as the radio system inevitably expands. Simulcast requires more equipment at each radio site, and reliable "backhaul" links to connect the tower sites together and to a central point. Although simulcast simplifies system operation from a users standpoint, it is more complicated than what is in place today. Thus, recurring costs are likely to increase under either simulcast Alternative. Recommendation 2: Implement mobile repeaters (Option 1). This could reduce the need to construct additional repeater sites to solve some portable radio coverage problems. Consider conducting a "pilot project" by implementing with a couple of units to evaluate their performance for possible expansion to more fleet vehicles. This will require licensing of an additional low power radio frequency. Use with a digital radio system should be investigated but should be possible. Recommendation 3: License an additional channel to provide flexibility (Option 3). A secondary frequency pair (channel) could eliminate community repeater operation, which would promote certain Alternatives. Alternately, such a channel might reduce the need for simulcast, particularly when the District expands operation along the San Mateo County coast (this channel could be placed at the best northern site, and play a role similar to the Black Mtn. channel (e.g., act as the default northern channel). Due to a shortage of frequencies in the Bay Area, such efforts are considered long-term (1-3 years), and would require a significant investment in resources without a guarantee of success. Recommendation 4: Convert radio system to narrowband operation before December 2009. Reprogram or replace equipment incapable of meeting the FCC-mandated narrowband requirement, and switch to narrowband operation before December 2009. Replacement equipment compatible with the District's legacy equipment will become increasingly difficult to obtain after this date. Narrowband conversion will ensure that compatible replacement equipment remains available. Recommendation 5: Assess and improve antenna systems at some tower sites. Assess and improve the coverage effectiveness of two existing sites by focusing on their antenna systems. Macro recommends the following: (a)Verify whether the Umunhum tower site antenna system is mounted and operating properly; (b) Consider raising the Sierra Morena antenna higher on tower and investigate whether some antenna systems components are still needed.

Some electrical grounding, seismic bracing and equipment chassis improvements are recommended at Umunhum, Coyote and Sierra Morena sites. Please see Section 2.4.3 for details. These could be performed over the next year, as none are considered major. In general, the tower sites were considered in good condition. Recommendation 7: Maintain operations on the 150 MHz (VHF) radio band. This radio band provides the most favorable coverage given the District's terrain, and provides interoperability with other key agencies, such as CDF, and various Santa Clara County agencies.

The decision of which transmitter to activate is based on which tower site had best received a signal from that unit, on the previous inbound transmission. Can allow multiple repeater or base stations to share a common radio frequency, since only one station is activated at a time. Primarily improves communications between dispatch and field units. Makes a slight communications improvement between field units,under certain conditions. Lower cost than simulcast. Community Repeater Operation A radio system configuration that allows separation of two or more groups of users on a single radio channel, through the use of private signaling codes.29 Allows users to mute messages from all but their own user group. Does not enable simultaneous use of the same radio channel by more than one user group, however. Applied only to conventional type radio systems. Conventional Radio System A type of radio system where each group of users operates on a pre-assigned radio channel and repeater(s). Each group owns, operates and maintains a private,stand-alone repeater system. Coverage The ability of a radio system to provide adequate radio signal strength and quality to allow users to communicate. FDMA Frequency Division Multiple Access. A method that creates different communications channels or paths by dividing the radio spectrum into numerous"slices"—each slice is then used as a channel to carry one message. Used by the majority of government and private businesses. Conventional radio systems are FDMA-type systems. Mobile Repeaters A vehicle-mounted device that enables a nearby portable radio user (+/- 1/4 mile away) to access the fixed radio network or repeaters through the high-powered vehicular radio. Extends the range of a portable radio equal to that of the vehicular radio. Used in lieu of adding additional tower sites for the purposes of improving portable radio coverage. 29 These codes are typically referred to a Private Line("PL"),Channel Guard("CG"),Continuous Tone Coded Squelch System(CTCSS). All conventional radios are capable of such operation. Improvement of the Two-Way Radio Communications System Page 38 Needs Assessment&Conceptual Design Report May 10,2006 F hOOPINWOULA RtaMNAL OF"IVAC*MIA= MACRO Over-transmission Refers to the collision of two or more messages on a radio channel. It occurs when a radio user, unaware of an ongoing conversation on the channel, attempts to make a radio call. This results in one or both messages becoming garbled and possibly lost. Simulcast A radio system configuration in which repeaters or base stations at different tower sites are configured to simultaneously broadcast the same message on the same radio frequency. Requires no user intervention when roaming to different areas. Provides"seamless"wide-area communications. Talk-In Mobile-to-base communications direction;uplink Talk-Out Base-to-mobile communications direction;downlink TDMA Time Division Multiple Access.A radio technology that interleaves multiple messages onto a single communications channel,one after another,while maintaining separation between the messages. In private government systems,TDMA can double or quadruple the capacity of the original analog method (FDMA). It divides each channel into multiple sub-channels providing a communications paths for up to four messages instead of one. Wide-area communications The ability of a radio network to allow two or more field users in different geographic areas to communicate,when they are not in range of the same communications tower site. It can be provided to some degree by Automatic Transmitter Steering,and to a significant degree by Simulcast technology or through use of a Zoned-type Trunking system. Improvement of the Two-Way Radio Communications System Page 39 Needs Assessment&Conceptual Design Report May 10,2006 WOMMOISMA R4040HAL OPM SVMM OWMCT MACRO APPENDIX B—COVERAGE PREDICTION MAPS Maps labeled as"talk-in"coverage represent the ability of the Dispatcher to hear a field unit, where the latter is operating through the network. Maps labeled as "talk-out" coverage (if present) represent the ability of afield unit to hear a Dispatcher or another field unit, when the latter operate through the radio network. Two map colors indicate where portables, and/or vehicles will experience less reliable coverage. Colors are defined as follows: Reliable Outdoor Portable Coverage Unreliable Portable,Reliable Vehicle Coverage ❑ Unreliable Portable and Vehicle In some cases, the maps are composites of two or more radio sites. This gives a good overall picture of system coverage. Existing System maps represent an existing wideband conventional analog system, or a digital system. The colored areas indicate areas where there is a 95% or greater chance, on average, that the signal strength will be adequate for a particular type of radio. The radio site locations are depicted as a yellow box containing an abbreviated site designation label. Maps predict "worst-case" radio coverage, i.e., coverage one could expect using a belt-mounted portable radio (using a remote speaker/microphone), or a vehicle radio equipped with a quarter-wave antenna on the vehicle trunk. Strongest (Mostly Likely) Server maps show where each site is predicted to have a signal stronger than any other site. However,they should not be used to predict coverage in all cases. Factors Affecting Portable Radio Coverage The portable radio's limited transmitter power and antenna performance cause it to be the limiting factor in the coverage of radio systems. A portable radio's transmitter power and antenna size is usually much less than that of a vehicle radio or a repeater. This can result in the system "talk-in" coverage being much worse than "talk-out" coverage. The ideal (or "matched") system has equal talk-in and talk-out coverage. This explains why there are typically more receivers than transmitters in a given radio system. Propagation Prediction Model The propagation maps are based on the "extended" Okumura prediction method with modifications to allow multiple-obstacle diffraction loss predications (the effects of rough terrain). Okumura's method was developed using actual measured data at several frequency bands in the Tokyo urban and suburban area. This method was computerized by Hata 30 in 1980, and was expanded to allow greater antenna heights and prediction distances than those of Okumura's original method. Signals weaken when there is an obstruction in the line-of-sight path between the transmitting and receiving antennas. This is called"diffraction-loss." Macro employed 30-meter terrain elevation points that were derived directly from 1:24,000 USGS maps. 30 M.Hata,"Empirical Formula for Propagation Loss in Land Mobile Radio Services",IEEE Transactions,Veh. Tech.,vol.29,no.3.pp 317-325,August 1980. Improvement of the Two-Way Radio Communications System Page 40 Needs Assessment&Conceptual Design Report May 10, 2006 SUOPENOMMA R6010"AL Oft"SP^Cg OtST"WT MACRO The original Okumura model allowed for selection of three different land-use categories to predict land- use and land clutter losses. Such losses are caused by signal absorption by trees, shrubs or other ground cover, including bodies of water and buildings. However, current computer-based methods allow use of up to ten different USGS and BLM land-use category classifications, each with varying loss factors that are frequency-dependent. Land use/land cover is categorized in areas of 250 x 250 meters. This propagation method is similar to that recently adopted by APCO and accepted by the Federal Communications Commission (FCC), as described in "TIA Telecommunications Systems Bulletin (TIA/TSB-88-B), Wireless Communications Systems — Performance in Noise and Interference Limited Situations; Recommended Methods for Technology Independent Modeling, Simulation, and Verification, September 2004".

Our discussion here concerns digital voice transmission. Digitization, with respect to wireless communications,refers to the conversion of speech sounds(which are "analog") into unique numbers or"replacement values." Unique combinations of I and 0 represent. these values. This 'conversion occurs in the radio unit itself. Once converted, the Is and Os are transmitted over-the-air though a repeater or to another radio where the reverse process takes place. The original speech is then emitted from the receiving radio's speaker. This is what makes digital systems less susceptible to eavesdropping and interception. Once voice is "digitized,,,31it becomes relatively easy to vary the assignment of values and order in which they are transmitted (loosely referred to here as the "protocol"). As long as the transmitting and receiving radios operate under the same protocol or rules,transmission and reception is possible. But, who determines the rules or protocols that dictate the assignment of numeric values to specific speech sounds?In lieu of a democratic standards-setting process, the first manufacturer to get a product into the market usually makes the rules. Yet, some protocols are open while others remain closed or proprietary. However, some "open" protocols still require manufacturers to pay intellectual property or license fees for the rights to use them. As with most current digital technologies, the industry "standard" is usually defined less by standard-setting bodies than by market penetration and widespread acceptance by users. Some manufacturers claim that the quality of a digital signal is better than that of an analog signal. This may be due to the simple fact that radio noise, such as static and some forms of interference, are analog- type signals. Since analog radios are designed to reproduce analog signals, both voice and noise can be reproduced, resulting in poor voice quality. Digital radios, on the other hand, only reproduce signals that contain discreet and well-defined signal values(combinations of I or 0), so random or continuously variable static noise is ignored. However, it is well known that a strong analog voice signal will have more clarity than a strong digital signal.32 But, once an analog signal starts to degrade, digital performs better. Thus,digital systems have an advantage when signals become weaker. Based on recent measurements and experience, Macro has found that some digital technologies will have slightly better range than analog. This is especially true when digital is compared with narrowband analog systems. One major advantage to digital systems is their tolerance of interference. Initial studies indicate that digital systems can tolerate significantly more co-channel interference than their analog counterpart. This will be an increasingly important benefit to agencies in congested areas. Due to design differences between analog and digital equipment, it is generally not possible to purchase an analog radio that is digital-capable or upgradeable. Normally, a digital-type radio must be purchased 31 The electronic process of converting voice sounds into numeric values prior to transmission(and vice-versa for reception). A Voice Coder("vocoder")performs these functions. 32 This is true today. However,Macro expects significant improvements over the next five to ten years. Improvement of the Two-Way Radio Communications System Page 49 Needs Assessment&Conceptual Design Report May 10, 2006 .............. WDPSNOMMA A69NONAL CW"SPACE WSTRICT MACRO at the outset and at a cost premium, although the agency may only intend to operate it in an analog mode. Digital radios can be expected to be backward compatible with analog systems. Regardless of whether a radio system is trunked or conventional, an agency could employ a mix of digital and analog trunks or channels. However, unless all user equipment is capable of digital operation, only digital radios could use digital trunked channels. However, since all digital user equipment is dual-mode,digital radios could use the analog radio trunks. Differences in Digital Technologies Significant differences can exist in voice quality and capability between competing digital systems. The resulting voice quality of digitized message is dependent on the hardware device (and accompanying software) that converts and reconverts the speech sounds to/from digital (it is called a voice coder, or "vocoder"). There are numerous vocoder types available, and in some modem radios, the vocoder can be changed or modified by uploading new software. Common vocoder types used in wireless communications include IMBE,AMBE, VCELP and CVSD. Another differentiating factor among digital systems is their ability to "embed" other information transparently within the voice message. Some digital systems transmit the coded speech information only and rely on traditional analog methods to implement other more advanced(although limited)feature sets. However, digital technologies capable of embedding can transmit other information, such as a user's identification number or name. Features such as single-button "canned" message transmissions, individual or group calling and paging, and the ability to disable or "stun" stolen or misused radios becomes possible. This helps system administrators to better manage large radio fleets. Some digital technologies have the ability to allow limited shared-use of a channel among different user groups using "group codes.,,3' This is similar to traditional Community Repeater operation. Some models will also permit use of receiver comparator equipment while also maintaining the group code function. Standards have been developed that will permit "data-encapsulation," or the embedding of digital information, such as vehicle computer inquiries and responses, in voice transmissions. A limited form of Adaptive Power Control (APQ is also possible in some models. This feature can reduce the transmitted power of a portable radio to optimize battery life 34 and reduce interference to nearby agencies. These features will operate optimally with radio technologies that employ Time Division Multiple Access(TDMA)methods,as opposed to Frequency Division Multiple Access(FDMA). 33 Not to be confused with trunking. This feature simply"mutes"and effectively locks-out users on the same conventional channel who do not have the same group code. 14 However,this will be partially offset by the somewhat power-hungry microprocessors in the radio,which make such features possible. Improvement of the Two-Way Radio Communications System Page 50 Needs Assessment&Conceptual Design Report May 10,2006 K"OPrNMAGMA RaOSONAL OP"*F^C6 04ST"ICT MACRO APCO Project 25 In an attempt to promote compatible interoperable digital two-way wireless communications products and system, APCO and numerous State and Federal agencies have developed a suite of technical standards for conventional and trunked digital radio systems for public-safety applications. Initiated in 1989 by APCO and standardized by TIA (Telecommunications Industry Association), this work is known as Project 25 (P25). Project 25 sought to create a standard for second generation digital and trunked radio systems and overcome the primary weakness of APCO 16: the lack of open systems and resultant competition among manufacturers. This fairly recent APCO standard applies to the implementation of conventional and trunked digital radio systems for public safety applications. One advantage of this newer standard is that it defines protocols and interfaces so that it is possible to utilize radios from different manufacturers in the same system. Implementation of this standard is becoming more common today as public safety agencies begin switching to digital radio; however,competition among manufacturers is still somewhat limited. There are currently three phases to the Project 25 process. Project 25 Phase I Phase I resulted in a 12.5 kHz bandwidth ("narrowband") FDMA35 set of standards consisting of 32 completed and published documents. The P25 Phase I standards were approved by ANSI in 1997. One key document describes the Common Air Interface (CAI), which is crucial in defining how radios communicate over-the-air. The P25 Phase I CAI requires that the control and messaging structure be transmitted at a gross rate of 9.6 kbps, of which 4.4 kbps is used for the digitized voice message 36 2.4 kbps is used for signaling,and the remaining 2.8 kbps is used for error correction. This provides for one voice message to be conveyed using 12.5 kHz of spectral bandwidth. Unfortunately, consoles and base station (repeater) standards were not developed during Phase 1, their interfaces are currently proprietary. Open console and base station interfaces will be part of the Phase 11 standards. Therefore, the vendor providing a Phase I system would probably provide the console system, limiting competition to only vehicles and portables radios. Therefore, real vendor competition may not be a reality until after the standards for Phase 11 are finalized and published. P25 Phase I system preliminary tests were recently completed at Motorola's factory for the Cities of Mesa and Phoenix, Arizona's trunked radio system with reported positive results. The participating vendors were Motorola, E.F. Johnson and IFR(IFR focused on radio test equipment). Other equipment manufacturers such as M/A-Com, Wulfsberg Electronics, BK Radio, and Kenwood are currently shipping Project 25 Phase I radios. At least forty-six manufacturers have signed the Project 25 Intellectual Property Rights(IFR)Memorandum of Understanding(MOU). Project 25 systems offer some major advantages over legacy analog systems. One of the advantages is that the P25 standards were developed in an open process that should result in competition from different manufacturers. P25 Phase I uses C417M (Compatible 4-level Frequency Modulation). C417M is a constant amplitude frequency modulation that allows the use of non-linear power amplifiers, allowing digital power levels to be similar to current power levels of today's analog equipment. An analog transmitter can therefore be replaced with a P25 Phase I digital transmitter with similar output power level. This results in radio coverage similar to that of the analog systems they are replacing, and Frequency Division Multiple Access. A method that creates different communications channels or paths by dividing the radio spectrum into numerous"slices"—each slice is then used as a channel to carry one message. .16 A"Vocoder",or voice coder is used to digitize human speech. This is the vocoder's output. Improvement of the Two-Way Radio Communications System Page 51 Needs Assessment&Conceptual Design Report May 10,2006 ............. MOVENOMULA PtGQ#ONAL CWSN*r^C2 04STfdCT MACRO 37 allows reuse of the same radio tower sites in most cases. P25 systems configurations include both conventional and trunked systems, including zoned and simulcast architectures. It should be noted that very few fully compliant Project 25 Phase I trunked systems have been installed or manufactured, although the list of participating manufacturers is growing. While Motorola's Astrov 25 model radio systems currently employ the Project 25 CAI for voice transmissions, some trunked models are still equipped with Motorola's lower-speed and proprietary control-channel signaling method found on their earlier analog systems. This is normally found on Motorola's Version 4.X Astro trunked systems. However, Motorola has announced their Astro(& 25 system version 6.X that will utilize the APCO 25 9.6 kbps control channel signaling protocol. Theoretically, V6.X will permit their trunked customers to use subscriber radios from other manufacturers. Project 25 Phase I systems are currently available and are considered robust and reliable enough for demanding government systems. They can be equipped with standard voice encryption products as well. They can also be implemented using the same repeater sites, frequencies, and many of the components that current analog systems use. Many federal government agencies, including the FCC and the District of Defense have embraced Project 25. In fact, P25 Phase I has been defined as the required standard for use on the new 700 MHz interoperability channels. As noted above, Phase I of Project 25 addressed systems capable of transmitting one voice message per one 12.5 kHz radio channel (e.g., FDMA). While this is compliant with current FCC Refarming rules affecting 150 and 460 MHz radio bands, these rules also required manufacturerS38 of equipment to eventually be capable of providing one voice message on a 6.25 kHz channel. Project 25 Phase I systems will not be capable of such operation. However, P25 Phase 11 systems are being developed to comply with this requirement. It is unclear, however, whether a Phase I system purchased today would require a major or minor upgrade. It should be noted that manufacturers produce many different tiers of user and fixed-end equipment. It is not uncommon for manufacturers to initially roll out their highest-tier and most expensive P25 Phase I radio models first, and follow later with lower-cost models. Project 25 Phase 11&III Phase 11 is currently underway with the goal of defining both FDMA and TDMA 39 standards to achieve 6.25 kHz bandwidth efficiency. P25 Phase 11 FDMA standards (6.25 kHz) have been completed for some time, but manufacturers are unable to build equipment due to some of the technology constraints that currently exist: linear amplifiers, frequency stability, battery size, etc., particularly for portable subscriber sets. The APCO P25 Steering Committee recently accepted a joint proposal from the European Defense and Security Networks(EDSN, also called EARS) and Nortel Networks to create a new P25 Phase 11 2-slot TDMA standard. This proposal offers backward compatibility with P25 Phase I conventional and trunked systems; uses the Phase I Common Air Interface (CAI) technology, control channel, data format, IMBE vocoder, and system identifications plans; and defines power levels similar to Phase I equipment,thereby assuring comparable coverage. Compatible Quadrature Phase Shift Keying (CQPSK) was the modulation technique selected for P25 Phase 11. CQPSK modulates both the phase and the carrier amplitude of the radio signal. This 37 Exceptions may include P25 simulcast systems. 38 Not end-users,however. 39 Time Division Multiple Access.A radio technology that interleaves multiple messages onto a single high-speed channel,one after another. Improvement of the Two-Way Radio Communications System Page 52 Needs Assessment&Conceptual Design Report May 10, 2006 ---- ------ `QV"WA"IX$r""Cr MACRO technique minimizes the width of the emitted signal allowing the bandwidth to be cut in half. The CQPSK demodulator in the P25 Phase 11 receiver will be capable of receiving a signal from either the C4FM or the CQPSK modulator. Therefore,during migration from P25 Phase I to Phase 11,the Phase 11 receiver would ensure interoperability with Phase I systems since its CQPSK demodulator will be able to detect and demodulate Phase I C4FM signals. The third phase of Project 25 deals with two different sub-phases of data standards. One phase is to develop a set of standards for use in 25, 50, and 150 kHz channel bandwidths in the US 700 MHz band, and the other would develop an international standard to achieve data rates of more than 2 Mbps. The latter standards effort is called Project MESA, an international standardization partnership on vehicle broadband technologies between TIA (North America)and ETSI (Europe). Encryption Encryption involves changing the form of a message, prior to transmission, such that the instructions to "undo" or reverse the changes are known by the intended recipient. These instructions or"codes" must be definable and changeable by the operator of the system in order to ensure secure message transmission. Encryption can be implemented in an analog or digital form. Today, analog encryption can usually comes in the form of a small circuit board that is installed in each radio, repeater and remote receiver. They are not an OEM(Original Equipment Manufacturer)produceo and are rarely installed by the radio manufacturer. These are adequate to protect communications from immediate security threats and to discourage casual eavesdropping. Users will experience degradation in voice quality, and sometimes range,when using analog encryption techniques. Digital radio systems are not automatically encrypted, although most can be considered moderately secure.4 1 Adding encryption to digital-type systems normally requires a software upgrade as opposed to any hardware modifications. Each manufacturer normally offers both its own proprietary encryption product, as well as the DES (Digital Encryption Standard) product that is in use by the federal government. DES is normally more secure, in that it employs a more sophisticated encryption key. Digital encryption can be employed on a conventional or trunked analog system. However, its voice quality and performance are normally quite poor. Most of these products were designed over eight to ten years ago before advances in voice compression and transmission. However, deploying encryption on a digital radio has little effect in range or voice quality,and is the preferred method. If encryption were employed on a trunked system, it would be available to all users, not just to specific groups of users. However, user equipment must also be capable of encryption as well. 40 These modifications usually void the equipment warranty unless installed by the radio manufacturer. 4'However,this is generally a function of limited availability of compatible and affordable digital receivers. Improvement of the Two-Way Radio Communications System Page 53 Needs Assessment&Conceptual Design Report May 10,2006 MOPOMMULA L OftN SPACE OWTV"Cr MACRO Digital Radio and Vehicle Data Systems Cities quite often consider implementing a digital voice radio system for vehicle data transmission. Although the Project 25 process lead to plans to integrate voice and data, very few if any have been implemented. In any case, Project 25 data will be limited to data rates around 7.2 kbps (much slower than a standard telephone modem). The difficulty is that data requires large amounts of bandwidth (or wide channel widths) for short periods, whereas voice requires small amounts of bandwidth for longer time periods. Voice infrastructures are not normally optimized for data transmission, and vice versa. Thus, manufacturers have not produced such equipment. Although M/A-COM and Motorola have implemented vehicle data on their analog trunked radio systems,users have had mixed results. The most common data systems today rely on a dedicated data channel and base station, with specialized and dedicated radio transceivers in vehicles. Macro sees no significant changes over the next five years.

Amended ►2/06 Regional Open Space .......... MIDPENINSULA REGIONAL OPEN SPACE DISTRICT R-07-18 Meeting 07-02 January 24, 2007 AGENDA ITEM 6 AGENDAITEM Authorize Additional Legal Fees in the Matter of Citizens for Responsible Open S12ace v. LAFCO and Midpeninsula Regional Open Space District and Authorize General Manager to Execute Retainer Agreement with the Law Firm of Shute, Mihaly & Weinberger for this Litigation. GENERAL COUNSEL'S RECOMMENDATION 1. Authorize payment of additional legal fees in the matter of Citizens for Responsible Open Space v. LAFCO and Midpeninsula Regional Open Space District in an amount not to exceed $30,000. 2. Authorize the General Manager to execute a revised retainer agreement with the Law Firm of Shute, Mihaly & Weinberger to represent the District in this litigation. DISCUSSION On April 7, 2004, San Mateo County Local Agency Formation Commission ("LAFCo") approved the District's Coastside Protection Program, which included an annexation application to extend District boundaries to the San Mateo Coast. Leading up to the submission of its application, the District engaged in a six year public process, including an advisory election and preparation of a Program Environmental Impact("EIR"). Litigation challenging the adequacy of the EIR was filed in July 2003. In April 2004, the Santa Clara County Superior Court ruled in the District's favor. On June 11, 2004, LAFCo conducted a protest hearing as required by law to receive any written protests to the annexation. On July 12, 2004, LAFCo issued its determination that insufficient valid protests had been submitted and that the annexation application therefore could become final. On June 5, 2004, litigation challenging these proceedings was filed against LAFCo and the District. On September 2, 2004, the San Mateo Superior Court issued its ruling denying a request to enjoin the Coastside Protection Program from proceeding. The litigation challenging these proceedings was later dismissed by the plaintiffs. On September 7, 2004, LAFCo filed the Certificate of Completion of the District's annexation of the Coastside Protection Area. The annexation is now complete and the District Board and staff R-07-18 Page 2 have been working continuously since then to implement all of LAFCo's conditions of approval. The District has begun purchasing land and providing services on the coast. On November 5, 2004, a subsequent lawsuit was filed against LAFCo, the District and the County of San Mateo challenging the validity of the annexation proceedings. This lawsuit sought to set aside approval of the annexation. It was the General Counsel's recommendation that the law firm of Shute, Mihaly and Weinberger be retained to represent the District in this litigation. This firm is one of the most highly qualified land use law litigation firms in the state and has extensive experience in this type of litigation. The firm also provided legal advice to the District during the lengthy course of development of the Coastside Protection Program and successfully defended the District in the two prior lawsuits challenging the Program. The Board approved retaining the Shute Mihaly firm and the District defended the current litigation throughout 2005 and 2006. On October 30, 2006, the San Mateo Superior Court issued its Statement of Decision ruling in favor of the District and LAFCO on all issues. On January 4, 2007, plaintiffs filed an appeal from the Superior Court's decision. The District needs to move promptly,to defend its position in this appeal. Accordingly, the Board is being asked to authorize the sum of$30,000 to cover legal costs associated with this appeal for this fiscal year. The District's FiscalYear 2006-2007 Planning Department budget for legal services for the Coastside Protection Program includes sufficient funds to pay for the requested legal services. Depending on further steps necessary to defend this litigation, and on the nature and complexity of other legal issues that may arise in connection with the appeal, staff anticipates returning to the Board in the future for additional expenditure authorization. If this occurs, this expenditure would be included in the Fiscal Year 2007-2008 Planning Department budget for legal services for the Coastside Protection Program. Lastly, the Shute Mihaly firm has discounted its standard rates for its representation of the District throughout its representation of the District on Coastside Protection Program matters and will continue to do so. The firm did not raise its rates for District services since 2003. The firm has now requested a relatively modest fee increase. Partner's rates will increase from $225 per hour to $250 per hour and associate's rates will increase from $190 per hour to $215 per hour. The firm's requested fees are very reasonable compared to similar firms, especially given the caliber of experience and services the firm is equipped to provide. General Counsel recommends the General Manager be authorized to execute a revised retainer agreement with the firm reflecting this fee increase.
