Protect and enhance the quality of Prior Lake’s surface waters. Public Safety 4. Ensure a safe and quality built environment. DISCUSSION: Introduction The purpose of this agenda item is to consider authorizing the execution of a contract to complete a stormwater outlet improvements project. History Staff has identified three critical locations with increased flooding potential and maintenance needs based upon routine stormwater system inspections and maintenance records. These locations are characterized by relatively large drainage areas flowing to one discharge point, where the flow of water is routed through a structure that can easily become clogged with debris. While these structures may be sized correctly to manage the expected flows under ideal conditions, problems arise when debris starts to accumulate at the structures. Potential issues include flooding, infrastructure damage, increased erosion and sedimentation, and increased inspections and maintenance costs. Current Circumstances The proposed project includes three locations: the outlet to the Arctic Lake system at Fremont Avenue NW, the Prior Lake Outlet Channel (PLOC) crossing at Jeffers Pass NW, and the outlet to Crystal Lake near the intersection of Village Lake Drive and Panama Avenue. The Arctic Lake system discharges into Upper Prior Lake through an outlet control structure at Fremont Avenue NW. There is a natural channel and wetland upstream from this structure that constitutes the source of the debris that frequently blocks the flow of water. Maintenance crews must inspect this structure after every significant rainfall event and clear debris to prevent localized flooding. Clearing debris can be difficult at this site as high water levels prevent easy access to the infrastructure. Flooding in this area has the potential to impact private property and existing City stormwater infrastructure that provides drainage for Fremont Avenue NW. The proposed solution is to install a new outlet structure designed to improve water flow and provide for easier maintenance and debris removal. There is also a significant amount of sediment accumulated where the Fremont Avenue NW drainage system enters the wetland. This sediment will be removed as part of the project. Removing sediment at pipe outlets is a standard stormwater system maintenance practice that helps to improve drainage function and water quality. The Jeffers Pass NW location is the first infrastructure restriction downstream from where the PLOC leaves Lower Prior Lake. The PLOC flows through a natural channel and wetland upstream of Jeffers Pass NW near Jeffers Pond Elementary School. This natural area is a source of debris for the system. In addition, periodic beaver activity has been documented here which compounds the debris problem. Flooding in this area has the potential to impact private property and City infrastructure. Maintenance crews have typically had a difficult time maintaining the existing structure due to difficult access and poor visibility when water levels rise above the pipe. In addition, accessing this area could be dangerous for personnel due to high water velocity. Flows through the PLOC can be significant during times of high water on Prior Lake, and all downstream infrastructure (including this structure) must be in good condition and able to pass design flows in accordance with our Memorandum of Agreement (MOA) with the City of Shakopee, City of Savage, Shakopee Mdewakanton Sioux Community (SMSC), and the Prior Lake-Spring Lake Watershed District (PLSLWD) to operate the PLOC. The proposed solution is to install a new outlet structure designed to improve water flow and provide for easier maintenance and debris removal. This type of structure is also designed to function where beavers are present. The Crystal Lake system discharges through an outlet pipe that enters Cates Creek, which drains to Upper Prior Lake. There is a natural channel just upstream from the outlet pipe that constitutes the source of the debris that can block the flow of water. In addition, periodic beaver activity has been documented here which compounds the debris problem. Maintenance crews must inspect this structure after every significant rainfall event and clear debris to prevent flooding. Clearing debris can be difficult at this site as high water levels prevent easy access to the infrastructure. Flooding in this area has the potential to impact private property, County ROW (Panama Ave/CSAH 23), existing City infrastructure, and City parkland. The proposed solution is to install a new outlet structure designed to improve water flow and provide for easier maintenance and debris removal. This type of structure is also designed to function where beavers are present. The project will include sediment removal near the new outlet structure. Plans (Attachment 1) were prepared and sent to three contractors. The City received three quotes (Attachment 2): Company Name Quote G.F. Jedlicki, Inc. $76,255.80 Krueger Excavating, Inc. $84,599.00 Kevin Casey, LLC $103,848.50 Staff is recommending that the City Council accept the quotes and award the project to G.F. Jedlicki, Inc. and approve the resolution to authorize the execution of the City’s standard contract for labor and materials for this project (Attachment 3). If approved, construction will commence in 2018 with substantial completion by June 30, 2019. ISSUES: The project design addresses the City’s concerns with ongoing maintenance requirements and flooding potential at all three locations. Suitable erosion and sediment control practices are incorporated into the design. The Minnesota Department of Natural Resources (MN DNR) will require permits for the Jeffers Pass NW and Crystal Lake project locations. These permits are currently under review and must be approved before any site work can commence. No MN DNR permit is required for the Fremont Avenue NW location. Scott County will require a ROW permit for accessing the Crystal Lake project location from Panama Avenue/CSAH 23l; the permit application is currently under review and is required before site work can commence. Staff coordinated with the SMSC and the PLSLWD to incorporate a carp barrier into the Arctic Lake outlet. The barrier will help to protect the water quality of an important Prior Lake tributary where all three of our organizations have previously collaborated on water quality improvement projects. The City has an obligation to protect and improve the water quality of our water resources. Additionally, we are under a State mandate to maintain our Municipal Separate Storm Sewer System (MS4). Allocating resources to complete this type of project shows a commitment to important aspects of our overall stormwater program. FINANCIAL IMPACT: The City’s budget includes funding for stormwater infrastructure maintenance and improvements within the Stormwater Utility Fund. Within this allocation, the Stormwater Outlet Improvements Project was identified. ALTERNATIVES: 1. Approve a resolution as part of the consent agenda authorizing the Mayor and City Manager to execute the City’s standard contract for labor and materials for the Stormwater Outlet Improvements Project. 2. Remove this item from the consent agenda for additional discussion.
