PUBLIC HEARING:
DATE:
INTRODUCTION:
The City of Prior Lake has filed an application for a Conditional Use Permit (CUP) to
allow the construction of a Water Treatment Facility (WTF) on the property located at
16335 Itasca Avenue. This site is zoned R-l (Low Density Residential). No variances
are required for this project.
BACKGROUND:
The City of Prior Lake draws the majority of our drinking water from the Jordan Aquifer.
In Prior Lake this aquifer is high in both iron and manganese. While the water is safe to
drink, the levels of these minerals present in the water exceed secondary drinking water
standards established by the Environmental Protection Agency (EP A). As a result
numerous residents experience water staining, odor and even taste issues at their
residences. These high levels also affect the life of water filters and softeners. In
addition to the impacts on residences, these minerals cause build-up in the water system
piping that can substantially reduce the capacity of watermains and water services. The
proposed Water Treatment Facility will improve the quality of water provided to our
citizens.
In January of 2006 the City Council created the Water Treatment Plant Committee
(WTPC). Since that time, the following has taken place:
. On June 5, 2006 the City Council held an informational meeting to discuss the
status of the Water Treatment Plant. At that meeting the City Council directed the
Water Treatment Facility Committee (WTFC) to proceed with the consultant
selection process.

Phone 952.447.9800 / Fax 952.447.4245
. On August 7, 2006, the City Council approved the City's Standardized Contract
for Professional Services with Bolton & Menk, Inc. and initiated the design report
for the Water Treatment Facility (WTF).
. From September to April, several neighborhood meetings were held with
residents to discuss various issues with the site and facility, including exterior
design and landscaping. Attendance at the meetings was primarily limited to the
residents living adjacent to the site.
Additionally, five issues of a project newsletter have been sent out to over 400
area residents. The City has also maintained a website and email distribution list,
to keep interested residents apprised of the latest project information.
The neighborhood's preference is for a building that has a residential appearance
and utilizes landscaping for screening and filtering of the building. The WTFC
feels that the concepts contained in the final design achieve these goals while
balancing the greater community's concerns of function and budget.
. On December 4, 2006, the design report was presented to the City Council for
approval. Issues considered by the Council included the facility size/capacity,
exterior architecture, fencing/security, budgeting, and storage. The Council
accepted the design report and authorized preparation of the plans and
specifications at the December meeting.
. On June 18, 2007, the City Council authorized the City's Standardized Contract
for Professional Services with Bolton & Menk, Inc. for design and construction of
the WTF.
PHYSICAL SITE CHARACTERISTICS:
Total Site Area: The site is approximately 7.8 acres.
Topoeraphv: The current elevations range from 922' MSL at the highest point
(northwest comer) to 904'MSL at the lowest point (east central). The site area where the
grading is proposed to take place will have elevations ranging from nO'MSL at the
highest point to 905'MSL at the lowest point.
Ve2etation: The site contains 257 insignificant trees (largely Boxelder species) and 5
significant trees on the site. The trees are predominately located in the southeastern half
of the site.
Wetlands: The site has one wetland located in the northwestern portion ofthe site that is
approximately 14,500 square feet. Due to necessary force main construction, an 18
square foot area of the wetland will be impacted. The minimal nature of this impact
1:107 rilesl07 cllP'slcity water treatmentlpc statTreport.doc
2
allows from an exemption of replacement requirements. A 30 ft setback will be
maintained from the delineated edge of the wetland.
Access: The site will be accessed from Itasca Avenue S.E.
Structures: Wells #3, #4, and #7 are located on the site. Wells #3 and #4 have well
house structures on the site.
2030 Comprehensive Plan Desi2nation: This property is designated for Urban Low
Density Residential on the 2030 Comprehensive Plan Land Use Map.
Zonin2: The site area is zoned R-l (Low Density Residential).
REVIEW PROCESS:
The proposed Conditional Use Permit should be reviewed in accordance with the criteria
found in Section 1102.304 and Section 1108 of the City Code.. Section 1102.304 includes
the specific conditions for the proposed use. Section 1108 includes the general CUP
criteria.
ANAL YSIS:
Storm Water: Storm water infiltration needs are being addressed with a proposed rain
garden in northwest comer of the site and a water quality pond in the southeast comer of
the site.
Si2ns: A monument ground sign will be proposed at the entrance to the site. The
entrance sign will be similar in size to those found at City parks (approximately 18 square
feet). In addition to a City logo, the building wall will also contain understated metal
lettering (similar in material to the metal lettering on City Hall). A sign permit will be
necessary prior to any signage installation.
Tree Replacement and Landscapin2: The proposed plan shows the removal of two
significant trees. The replacement requirements will be exceeded with the establishment
of 173 caliper inches of trees. The landscape plan meets the Code requirements.
Li2htin2: The City Code specifies that reflected glare or spill light shall not exceed a .5
foot-candle at the property line when the source of light abuts any residential uses. All
fixtures will be downcast. A photometric plan has been completed which shows that that
this condition will be met.
Architecture: The WTF will use three different roof types: hip, gable, and flat. In the
areas where the flat roof is located, a mansard type roof with parapet will be utilized to
screen any rooftop equipment. The main entrance, utility meters, and transformers are
1:107 fi1es107 cllp'slcity watcr trcatmcntlpc staffreport.doc
3
proposed to be located on the SE side of the building, away from the closest residents
(elevations attached along with computer renderings).
The proposed WTF will be approximately 37,135 square feet in gross area (including the
upper level mezzanines). In addition, a 7.5 million gallon reservoir will be located below
ground (covered with a grass roof). The interior of the building will house the treatment
infrastructure, along with space for the storage of water related equipment (meters, Ii ft
station supporting equipment, back up generators, etc). The WTF will also house a lab
for testing water samples, a garage for the storage of the Vactor (vacuum) truck, and a
conference/office space (see attached main floor layout). No outdoor storage is proposed
for the WTF.
The traffic at the WTF will consist of Public Works vehicles traveling in and out of the
site multiple times during the workday. The Water Department staff will be based out of
the WTF and the facility will house the vacuum truck, p0l1able generators, and other
Water Department equipment. In addition, chemicals used for the treatment of water will
be delivered approximately once per month. On weekends, traffic to the site will consist
of the on-call water staff conducting rounds once per day. There may be traffic to/from
the facility during non-working hours as the Public Works staff responds to emergencies
at the treatment facility or out in the system.
Other Requirements: Section 1102.403 (2) of the Zoning Ordinance lists the specific
conditions for public service structures. These are:
a. All exterior faces of all buildings shall meet the provisions of subsection 1107.2200.
The CUP requires that the WTF have 60% Class 1 materials on all sides in
accordance with City ordinances. The proposed facility exceeds this requirement by
ranging from 61 % to 69% on the building (glass and brick).
b. All structures shall be located a minimum of 15 feet from any lot in an "R" Use
District.
This requirement will be exceeded.
c. A bufferyard, Type C as defined in subsection 1107.2005, shall be installed and
maintained along all property lines abutting an "R" Use District.
The bufferyard requirements will be met. The attached landscaping plan details the
extensive trees and landscaping that will be installed.
CONDITIONAL USE PERMIT (CUP) ANALYSIS:
Section 1108.200 of the City Code sets forth the criteria for approval ofa CUP.
