CITY COUNCIL AGENDA REPORT
MEETING DATE: FEBRUARY 5, 2018
AGENDA #: 5G
PREPARED BY: PETE YOUNG, WATER RESOURCES ENGINEER
PRESENTED BY: PETE YOUNG
AGENDA ITEM: CONSIDER APPROVAL OF A RESOLUTION ACCEPTING BIDS AND
AUTHORIZING THE EXECUTION OF THE CITY’S STANDARD
CONSTRUCTION CONTRACT FOR THE SAND POINT BEACH PARK
PONDS MAINTENANCE AND RETROFIT PROJECT
DISCUSSION: Introduction
The purpose of this agenda item is to seek City Council authorization to
enter into the City’s standard construction contract for the Sand Point
Beach Park Ponds Maintenance and Retrofit Project.
History
Each year the City Council adopts the Capital Improvement Program (CIP)
which involves funding for various improvement projects. The CIP calls for
stormwater pond maintenance and retrofits to ensure proper function of the
City’s network of stormwater ponds. The Sand Point Beach Park Ponds
Maintenance and Retrofit Project was identified within the CIP allocation.
The existing ponds, adjacent to the Sand Point Beach Park parking lot,
were constructed in 1984 to slow down the rate of runoff entering Lower
Prior Lake. They were not originally intended to provide water quality
treatment. Over the past 34 years, the ponds have filled with excess
sediment from a 65-acre contributing drainage area, limiting their
effectiveness. Major maintenance is needed to return the ponds to their
original condition and restore their rate control capacity.
Staff worked with the Prior Lake-Spring Lake Watershed District (PLSLWD)
and identified the ponds as a water quality retrofit opportunity under the
PLSLWD’s Lower Prior Lake Diagnostic Study and Implementation Plan
(2013). The PLSLWD subsequently applied for and received state grant
funding for completing projects identified in the Study, including the Sand
Point Beach Park Ponds Maintenance and Retrofit Project. The PLSLWD,
through a combination of their budget and grant funds, allocated
approximately $130,000 to help complete enhanced water quality
treatment as part of the project.
Current Circumstances
Sand Point Beach Park is one of our five popular Community Parks and
one of our most visible amenities. Performing the needed maintenance,
2
while improving water quality using outside grant funding, represents a rare
opportunity to treat runoff from a large drainage area and make a major
impact on water quality for Lower Prior Lake.
The project design includes both regular pond maintenance items and
retrofit items targeting enhanced phosphorus removal. Regular pond
maintenance items include sediment removal, stormwater structure
replacement, pond expansion, and site restoration. Enhanced phosphorus
treatment, funded by the PLSLWD, includes installation of an iron-
enhanced sand filter (IESF). The City and PLSLWD previously worked
together to successfully install a similar IESF at Fish Point Park to address
excess phosphorus loading.
Water discharging from the ponds enters a bay of Lower Prior Lake near
the end of Shady Beach Trail NE. Based on past communications with
local residents, this bay is shallow and experiences periodic algae blooms
along with heavy aquatic vegetation growth. Phosphorus is a nutrient
needed for plant growth, and when it is available in excess quantities in
surface water, it can drive algae blooms. The proposed project directly
addresses phosphorus loading, increasing the pond system’s annual
phosphorus treatment capacity by 172% (15.4 lbs to 41.9 lbs). Treating this
additional 26.5 lbs of phosphorus could potentially reduce algae in Lower
Prior Lake by over 13,250 lbs each year. This number, based on the
common approximation of 1 lb of phosphorus resulting in the potential
growth of 500 lbs of algae in surface water, provides another way to help
quantify the potential impact of the project.
Plans and specifications (Attachment 1) were prepared by the City’s
consulting engineer for this project and advertised for bid. On February 2,
2018, 6 bids were received and publicly opened and tallied as follows:
Company Name Bid
BKJ Land Company $298,485.10
GF Jedlicki, Inc. $383,431.50
Landwehr Construction, Inc. $397,740.70
New Look Contracting, Inc. $296,450.50
Peterson Companies $388,398.00
Valley Paving, Inc. $347,325.40
Conclusion
Staff is recommending that the City Council accept the bids and award the
project to New Look Contracting, Inc. and approve the resolution to
authorize the execution of the City’s standard construction contract for this
project (Attachment 2). The PLSLWD funding will be secured through
agreement (Attachment 3). If approved, construction will commence in
February 2018 with substantial completion by May 25, 2018.
ISSUES: City staff worked with our engineering consultant to ensure the project
design considers the future maintenance burden on Public Works staff.
3
Long-term maintenance costs must be a primary consideration when
designing stormwater infrastructure systems. Maintenance during the
establishment phase must also be considered. The PLSLWD has agreed
to maintain the IESF during the establishment phase (first two years af ter
project completion). Regular maintenance will be simple, consisting of
periodic rough mowing of pond side slopes and maintenance of the IESF
surface.
On December 11, 2017, seven 5th graders from Sage Academy Prior Lake
Savage Area Schools and St. Michaels Catholic School who are part of the
Circuit Surge robotics team presented information in support of this project
to the City Council during the Public Forum. Staff will provide updates to
the team regarding this project, including potential learning and volunteer
opportunities at the site during and after construction.
The City has an obligation to protect and improve the water quality of our
water resources. We are under a State mandate to maintain our Municipal
Separate Storm Sewer System (MS4). Allocating resources to complete
this type of MS4 maintenance project shows a commitment to an important
part of our overall stormwater program.
FINANCIAL
IMPACT:
The City’s CIP reserves $300,000 in 2017-2018 for stormwater pond
maintenance and retrofit implementation. Within this allocation, the Sand
Point Beach Park Ponds Maintenance and Retrofit Project was identified.
Funding for this project will be taken from Account # 602-49420.00-
55530.00. The PLSLWD will provide up to $130,000 to fund enhanced
water quality elements of the project through a funding agreement,
resulting in a cost of $166,450.50 to the City based on bids received.
ALTERNATIVES: 1. Motion and a second as part of the consent agenda to approve the
resolution which authorizes the Mayor and City Manager to execute the
City’s standard construction contract with New Look Contracting, Inc. for
the Sand Point Beach Park Ponds Maintenance and Retrofit Project.
2. Motion and a second to remove this item from the consent agenda for
additional discussion.
