2017 Willow Water Tower Rehab Project
Background
The water tower located on Willow Drive was constructed in 1987. Over the past 30 years the
exterior of the tower has been power washed and painted at least twice, last time being in 2009,
with the interior of the tank going untouched. In 2012 the City contracted with KCI to do a tank
and tower inspection to determine the condition of the structure. The report from KCI concluded
that the tower has held up remarkably well considering there was no maintenance done to the
interior. There is, however, some spot rusting and pealing of paint that needs to be addressed.
Direction and Choices
The direction that is being recommended is to have the interior tank and dry sections sand
blasted and repainted, while the outside will be spot repaired and painted. There is also the
question of paint color, as well as if our City logo should be added to the tower. The tower has
been two different colors in its lifetime. The first was a tan color with a simple Medina name
band painted on the bowl section. In 2009 the City Council decided to have the tower painted
sky blue and to save money the Council chose not to add a logo or identification. We have not
included any costs for these two items in the bid package. Ballpark estimates gathered suggest
that a simple band with Medina on it will be in the $10,000 range, and the Medina logo would be
in the $20,000 range. These options can be discussed at the work session.
Process and Concerns
The project process will be fairly complicated given the fact that the water tower will be out of
service for approximately six weeks. During this time, the tower will be drained and the City will
be running its water on its high service pumps. If everything goes perfect, no one will notice any
pressure change and quality will remain the same. The reality is that someone will illegally use a
fire hydrant, or we could have a fire in town and water pressure will fluctuate during this period.
Staff will do everything we can to notify our customers and we may impose a sprinkling ban or
at least limit irrigation during the project. There will be more planning prior to the start of this
project to insure the City supplies quality safe water throughout the project.
Project Cost and Staff Recommendation
The total project cost is estimated to be very close to the $400,000 budgeted for the project in
2012, with approximately $337,800 in construction costs and the estimated engineering fees.
Staff recommends approving the resolution on the Dec. 20th Consent Agenda and moving
forward with the bidding process for the water tower rehab project as shown in the bid
documents provided by WSB, with the existing sky blue color and no logo as it exists today, for
the estimated construction cost of $337,800.

SUBJ: Conservation Design-PUD Discussion
Background
In 2010, the City adopted an ordinance establishing regulations for a Conservation Design
Planned Unit Development (CD-PUD) process as an alternative to conventional development
practices. The CD-PUD is intended to encourage conservation and protection of natural resource
areas and open space by offering flexibility to developers in exchange for the applicant placing
portions of the property into permanent conservation. The primary flexibility offered for
residential development is an increase in the base density. For a rural CD-PUD, the ordinance
permits the City Council to grant up to a maximum of double the base density. The City
maintains full discretion to determine how much flexibility, including bonus density, is
justifiable based upon the extent to which the proposal meets conservation objectives.
Since the ordinance was adopted, the City has reviewed three requests for CD-PUD
developments. All three requests were for rural CD-PUD projects, and all three requested the
maximum bonus density. The requests were the Marx CD-PUD (east of Parkview Drive and
north of CR24), the Deerhill Preserve (aka Stonegate) CD-PUD (east of Homestead Trail and
west of Deerhill Road), and a portion of the Dellcroft CD-PUD (west of Arrowhead, south of
Hamel Road). Two of the requests were not carried through after it appeared that the Planning
Commission and City Council were not going to support the requested density bonus. Deerhill
Preserve was approved by the City with a density bonus which was just under the maximum
allowed. In the case of Deerhill Preserve, over 90 acres of property was placed into permanent
conservation (of which over 30 acres was buildable). The developer received approval for 41
lots, where conventional development would have been limited to 22 lots.
After the review of Stonegate/Deerhill Preserve and the Dellcroft requests over the last year, a
number of Council members expressed an interest in reviewing the CD-PUD ordinance. Staff s
impression is that Councilmembers may be interested in discussing whether the doubling of
density is too large of a bonus. Staff intended to schedule the discussion for a City Council
worksession after staff had completed much of the work on the Comprehensive Plan.
It should be noted that the City recently received a Concept Plan Review request for a CD-PUD
subdivision from Wally and Bridget Marx along Parkview Drive. The concept has been
amended since the review a number of years ago.
Ordinance Description
The CD-PUD ordinance is attached for reference. In addition to density bonuses, the ordinance
also allows flexibility for setbacks and park dedication fees. The CD-PUD ordinance requires a
minimum of 30% of the buildable area of property to be included in the conservation area.
Conservation Design-PUD
Page 1 of 2 December 20, 2016
Discussion City Council Worksession
The CD-PUD ordinance is intended to offer incentives to developers in order to encourage
conservation. The incentives need to be substantial enough to offer such encouragement if the
ordinance is to serve its purpose. However, it is important to remember that the City ultimately
has the discretion to determine whether the amount of flexibility requested is justified by the
extent to which the proposed CD-PUD meets the City's conservation objectives better than
would be achieved through conventional development.
If Councilmembers would like any additional information to assist with the worksession
discussion, please let me know.

areas and facilities.
Section 827.67. Conservation Area Design Standards.
The following Conservation Area design standards shall also be considered in designing the
CD-PUD:
Subd. 1. Conservation Areas should be interconnected wherever possible to provide a
continuous network of Open Space within the PUD and throughout the City. It should
coordinate and maximize boundaries with Conservation Areas and Open Space on adjacent
tracts.
Subd. 2. Incorporate public and private trails with connections to existing or planned
regional trails as identified in the most recent Park, Trail and Open Space Plan.
Subd. 3. Designated public access trails shall be protected by an access easement owned
by the City.
Subd. 4. Incorporate public and/or private Open Space as designated in the
Comprehensive Plan.
Subd. 5. Views of new dwellings from exterior roads and abutting properties should be
minimized by the use of existing topography, existing vegetation, or additional
landscaping. Ridge and hilltops should be contained within designated Conservation Areas
wherever possible. Trees should not be removed from ridges and hilltops.
Subd. 6. The boundaries of designated conservation areas shall be clearly delineated and
labeled on CD-PUD plans. These areas shall be delineated in the field with signage or
other measures approved by the city.
Subd. 7. Stormwater management facilities may be located in designated conservation
areas.
Subd. 8. Existing land in row -cropping use shall be converted to a use that supports the
achievement of the City's conservation objectives.
Section 827.69. Landscape Design Standards.
Subd. 1. Street trees may be planted, but are not required, along internal streets passing
through common Conservation Areas or Open Space.
Subd. 2. Irregular spacing is encouraged for street trees, to avoid the urban appearance
that regular spacing may invoke.
Subd. 3. The selection of vegetation should be guided by the natural community types
identified in the City's 2008 Natural Resources Inventory.
827. Zoning — Zoning Districts Page 33 of 36
Medina City Code 827. Zoning Zoning Districts
Subd. 4. Planted buffers between clusters of residential lots are encouraged to enhance
privacy and a rural appearance between lots.
Subd. 5. Buffers consisting of an informal arrangement of native plant species combined
with infrequent mowing are strongly encouraged, to create a low -maintenance, natural
landscape.
Subd. 6. Planted buffers are also encouraged along natural drainage areas to minimize
erosion.
Subd. 7. Grading for Conservation Areas and other common landscaped areas and
stormwater management areas shall be avoided to reduce compaction and impacting water
infiltration rates. Soil testing and decompaction may be required if site construction
activities negatively impact soil permeability.
Subd. 8. Better Site Design/Low Impact Development practices as identified in the
Minnesota Stormwater Manual published by the Minnesota Pollution Control Agency shall
be used to design sites and meet the performance standards.
Section 827.71. Subsurface Sewage Treatment Facilities.
Subd. 1. Where city services are not available, CD-PUD developments may be platted to
accommodate home site lots with either individual septic tanks and all required
drainfields/mound systems located on the lot, or individual septic tanks and primary
drainfield/mount system located on the lot and secondary drainfields/mound system
located in the designated Conservation Area or other Open Space.
Subd. 2. All septic systems shall conform to the current performance standards of
Minnesota Rules Chapter 7080 and its appendices, or the amended Rules in effect at the
time of installation. Except in instances where flexibility has been explicitly granted by
the City, septic systems shall also conform to relevant City regulations, including the
requirement to identify a primary and secondary drainfield site.
Subd. 3. The City may consider shared sewage treatment systems which are consistent
with Minnesota Pollution Control Agency (MPCA) regulations and relevant City
ordinances, provided adequate agreements are in place related to monitoring and
maintenance procedures and replacement of the system in case of a failure.
Subd. 4. Secondary drainfields/mound systems may be located in designated
Conservation Areas and other Open Space provided that:
(a) They are located within a limited distance of the lots they serve.
(b) Construction of drainfields/mound systems do not result in the destruction of
ecological resources.
(c) The Conservation Area or Open Space parcel containing the drainfield/mound system
is owned in fee by a common ownership association which owns non -Conservation
827. Zoning — Zoning Districts Page 34 of 36
Medina City Code 827. Zoning Zoning Districts
Area land within the subdivision and in which membership in the association by all
property owners in the subdivision is mandatory.
(d) The individual lot owner is responsible for maintenance and repair of the
drainfield/mound system.
(e) The ground cover over the drainfield/mound system is maintained according to the
Land Stewardship Plan.
(f) Recreational uses are prohibited within 50 feet of the drainfields/mound systems.
(g) The Conservation Easement for the dedicated Conservation Area parcel describes the
location of individual drainfields/mound systems.
Section 827.73. Site Design Process.
At the time of PUD Concept Plan development and review, applicants shall demonstrate that
the following design process was performed and influenced the design of the concept site plan.
Subd. 1. Step 1—Identify Conservation Areas. Identify preservation land in two steps.
First identify "unbuildable" areas which include: slopes greater than 18%, wetlands,
wetland buffers, lakes, and land within the 100 year floodplain. Next, identify
Conservation Areas which include those areas designated as Conservation Areas (Section
827.59 Subd. 3.) The remaining land shall be identified as the potentially Buildable Land
Area. The applicant shall identify the quantity of land designated as unbuildable,
Conservation Area, and potentially Buildable Land Area.
Subd. 2. Step 2—Locate Housing Sites. Locate the approximate sites of individual
houses in regard to protected views and the potentially buildable land areas.
Subd. 3. Step 3—Align Streets and Trails. Align streets in order to access the lots.
New trails and connections to regional trail systems, if any, should be laid out to create
internal and external connections to existing and/or potential future streets, sidewalks, and
trails.
Subd. 4. Step 4—Lot Lines. Draw in the lot lines.
Section 827.75. CD-PUD Application Processing.
The review and approval procedures of the PUD District shall be used to review and approve
CD-PUDs. Prior to the Concept Plan Stage PUD application, the City encourages applicants to
engage in an informal collaborative project goal setting process with the City. The purpose of
this process is to jointly develop site design and conservation objectives and assess areas of
regulatory flexibility for achieving developer and City objectives for the specific parcel of land.
The Collaborative Process may include council members, city commission members, land
owners, developers, city staff, other governmental jurisdiction staff, the potential future
Conservation Easement holder, and other participants as appropriate. The outcome of the process
is a Project Guidance Report prepared by city staff. The report will summarize the project
concept, project objectives, and preliminary understanding of regulatory flexibility needed to
827. Zoning — Zoning Districts Page 35 of 36
