(PLANS ONLY) City of San Mateo Department of Community Development February 17, 1984 PA84-10 CREEKSIDE STAFF FINDINGS ON THE NEGATIVE DECLARATION PROJECT DESCRIPTION: The proposed project involves the construction of 192 residential condominium units on an 8.75 acre vacant site. The unit will be located in 13 separate buildings: two eight -unit buildings and eleven 16 -unit buildings. The unit sizes range between 576-686 square feet for the 104 one -bedroom units, and 780-873 square feet for the 68 two -bedroom units. Three three-story buildings have a level of parking partially below grade; the ten remaining structures are two-story with no enclosed parking. Maximum building height to the plate line is 22 feet. Of the total 306 parking spaces provided, 76 spaces are located in the sub -grade garages, 116 spaces are covered by carports, and 104 spaces will be open. Alternating sections of six-foot high wrought iron and solid cedar fencing along the site perimeter and the north side of San Mateo Creek, and an internal gate system will provide security to the parking areas and residences. A recreation building and pool area will be located near the project entry at the west end of the site. A single driveway along East Third Avenue provides site access. A 20 -foot wide bike path/maintenance road parallel to San Mateo Creek will also provide emergency access at the project's east end. The applicant is requesting the following City permits: 1. Site Plan and Architectural Review - for the details of construction of 192 residential condominium units in the two-story and three three-story buildings. 2. Planned Development - for 192 residential units. 3. Site Development Permit - to allow grading and removal of major vegetation. 4. Tentative Map - to subdivide property into 192 condominium units and common area. PA84-10 CREEKSIDE STAFF FINDINGS ON THE NEGATIVE DECLARATION February 17, 1984 Page 2 LOCATION AND PROPONENT: The project is located on the south side of East Third Avenue near Norfolk Street, along the north side of San Mateo Creek in the South Shoreview Planning Area (Assessor's Parcels 033-243-020 and 033-271-310). The applicant is Lincoln Property Company, 101 Lincoln Center Creek, Foster City, CA 94044 by J. Woodson, as represented by Panko Sinclair Associates, 15 North Ellsworth Street, San Mateo, CA 94401 by Niles Tanakatsubo. IMPACT ANALYSIS: Environmental impacts are discussed in the negative declaration prepared for the previous 192 -unit residential project approved for this site (PA80-99 Baycreek Condominiums). The previous negative declaration was certified by the City Council on November 16, 1981. A revised Initial Study checklist was prepared for the new project based on the findings of the previous negative declaration. The following impacts as described in that document are affected by the new site plan and exterior appearance of the new project; only the relative changes between the original Baycreek Condominiums project and the new Creekside project are described below, with updated discussion of the special studies and design measures required as conditions of the original project approval. 1.3 Drainage and 1.4 Channel Form To improve the flood carrying capacity of San Mateo Creek, the creek channel will be dredged, and widened. A permit for creek improvements from the U.S. Army Corps of Engineers was secured as required for the previous project; the permit expires on October 26, 1984, but is renewable (Tanakatsubo 1984) The applicant must request modification of the Army Corps of Engineers permit to reflect the new project. 2.1 Air Pollution Widening of East Third Avenue into a divided highway with two lanes in each direction has been approved. Surcharge and fill operations for the roadway are currently in process, with roadbed construction anticipated to commence in the Spring of 1985 (Binkley, 1984). With the additional capacity, improved traffic flows are anticipated despite increased traffic volumes; by reducing emissions due to decreased delays and idling times, the widening may have a beneficial impact on air quality. PA84-10 CREEKSIDE STAFF FINDINGS ON THE NEGATIVE DECLARATION February 17, 1984 Page 3 3.2 Foundation Support and 3.3 Seismic Activity The previous soils report by Jo Crosby and Associates dated April 30, 1980, contains recommendations for foundation support and seismic safety. A new soils report will be required prior to issuance of any building permits to address the different load bearing characteristics and design recommendations for the revised building heights and footprints. 3.7 Landscape Suitability Due to the variable age and composition of fill„ a soil test will be required to determine whether soil amendments are suitable for the establishment of required landscaping. 6.1 Sewage Treatment Facilities Estimated sewage flows will be reduced from 51,000 gallons to 38,500 gallons per day based on reduced population anticipated to occupy the smaller units. A sewer line capacity study will be required to determine whether the existing sewer lines servicing the project are adequate to accommodate anticipated flows. The applicant will contribute toward upgrading service lines if necessary as determined by the City's Developer's Contribution Policy. 6.2 Solid Waste Disposal Since fewer residents are expected to occupy the units, the amount of solid refuse generated will decrease from an estimated 1,116 pounds to 840 pounds per day. Adequate capacity exists at the Ox Mountain disposal site near Half Moon Bay. 6.3 Water Supply Projected water demand will be altered by the reduced population and the increased landscaped area. Water supplies are adequate to supply the projected demand, although a new water main will need to be constructed, as previously recognized. The emphasis on native drought resistant plant materials as proposed in the preliminary landscape plan will further reduced water demands. PA84-10 CREEKSIDE STAFF FINDINGS ON THE NEGATIVE DECLARATION February 17, 1984 Page 4 6.4 Storm Water A Storm Drainage Study will be required by the Public Works Department prior to issuance of any building permits. Storm drainage will drain towards San Mateo Creek, with only a small amount of runoff from the on -site grade transition areas between East Third Avenue and the project site draining toward the East Third Avenue storm sewer (Tanakatsubo 1984). 7.1 Educational Facilities Due to a reduction in unit sizes to include fewer two -bedroom units the estimated population is reduced from 465 to 350 persons. Projected enrollment in educational facilities will reduce proportionately. 7.2 Police Services Standard conditions of project approval imposed by the Police Department require parkings stalls for residents' vehicles to be fully enclosed and separate from public visitor and commercial spaces. Only 78 of the 268 required resident spaces will be located in enclosed garages; the western- most garage should be secured with a gate since it is located outside the interior gate system. The remaining spaces will be located in carports and open stalls secured by card key operated gates near the project entries. A perimeter security fence is intended to provide security for the parking areas as well as additional security for the households. By discouraging non-resident vehicles from driving into the core of the development, the likelihood of vandalism and theft in the carport is reduced. 7.4 Park and Recreational Facilities Estimated new residents will number 350 people, rather than 465 persons anticipated for the previous project. On -site recreational facilities include a recreation building, swimming pool and spa which will decrease demand for off -site facilities; however the proposed recreation area is not centrally located for the majority of residents. A bicycle path/maintenance road will also be developed south of the residences parallel to San Mateo Creek. 8.1 Traffic Volumes and 8.2 Circulation With the decreased number of residents, daily vehicle trip ends (VTE) may also decrease slightly from the original estimate of 1,440 VTE. The project entry on East Third Avenue will be signalized. With completion of the East Third Avenue widening, traffic flow will be improved. PA84-10 CREEKSIDE STAFF FINDINGS ON THE NEGATIVE DECLARATION February 17, 1984 Page 5 With distribution of compact parking spaces concentrated at the eastern end, standard size vehicles can be expected to parking in compact stalls. Since most of these spaces will be utilized by guests who are unfamiliar with the site, the compact spaces should be redestributed more evenly throughout the project site. 10.1 Noise Levels The East Third Avenue frontage will be fenced with alternating sections of six-foot high solid cedar and open wrought iron fencing; no masonry sound wall is proposed as a noise barrier. An Acoustical Report will be required detailing measures to be taken to reduce interior noise levels to acceptable residential standards per Title 25 of the California Administrative Code. 11.1 Land Use Compatibility As part of the action approving the previous Baycreek Condominium project, the property was reclassified to R4 (Multiple Family Dwellings - Medium Density Apartments) for the development portion and S (Shoreline) for the San Mateo Creek portion. Building height has been reduced to two stories for ten of the 13 buildings, consistent with the height of neighboring residences. 12.1 Views Views of the project site will be altered by the change in exterior materials, reduced building height and proposed fencing along the property line. While alternating sections of solid cedar fencing afford a sense of privacy to the perimeter residences, the solid wall obscures views of the site landscaping from off -site locations. With curb, gutter and five-foot wide sidewalk to be installed as part of the East Third Avenue widening, the remaining right- of-way available for landscaping is minimal; landscape plans for the East Third Avenue right-of-way have not been designed (Binkley 1984). Solid sections of fencing as long as 230 feet will extend along East Third Avenue which is a proposed scenic highway. The observer's perception of long sections of solid fencing is more obvious to pedestrians, cyclists and neigh- boring residences than to motorists who will pass the site at high speeds. Several measures can be recommended to improve this view: 1. Reduce the length of the alternating sections of solid fencing by installing more sections of open fencing; 2. Offset the fencing from the property line to provide on -site planter areas outside the fence line; or 3. Contribute towards street beautification along East Third Avenue. PA84-10 CREEKSIDE STAFF FINDINGS ON THE NEGATIVE DECLARATION February 17, 1984 Page 6 13.2 Archaeological Resources A Citywide Archaeological Report has been prepared as an inventory of known sites and potential areas of archaeological significance (Chavez 1983). The sensitivity map which accompanies the report designates the site in a medium sensitivity zone; while no archaeological sites have been recorded in this zone, their similarity and proximity to discovered sites suggest a moderate potential for containing important deposits. An archaeological reconnaissance of the site will be required prior to issuance of a building permit. FINDINGS: The previously -certified negative declaration for Baycreek Condominiums (PA80-99) is adequate to address environmental impacts resulting from the project as modified because the proposed changes are not significant enough to alter the level of impact. The measures recommended in the environmental document to reduce potential impacts are applicable to the modified project.
