either be provided on -site as part of the Rivers Bend Regional Stormwater Improvements by utilizing filtration practices as allowed by LRRWMO stormwater standards, or off -site in a regional infiltration basin located outside the East DWSMA. City staff discussed various aspects of this project with LRRWMO and MPCA staff, including potential wetland impacts, options for meeting volume retention requirements, and how the timing of this project could be coordinated with the Lightbridge Academy development construction to ensure adequate stormwater runoff treatment can be provided during construction of both projects. Staff coordinated the construction schedule of the City's stormwater pond improvements project with the Lightbridge Academy development construction schedule to address concerns raised by the LRRWMO. Lightbridge Academy's engineer prepared and submitted a phased construction plan with their LRRWMO permit application, which was approved. Lightbridge Academy will construct their building first, along with two temporary stormwater retention ponds to manage stormwater runoff, thereby minimizing disturbance to the site while the Rivers Bend Regional Stormwater Improvements project is under construction. Lightbridge Academy will then complete their site improvements, including impervious surface improvements, during the final construction phases of the Rivers Bend Regional Stormwater Improvements late this Fall or next Spring. As of the time this report was prepared, Lightbridge Academy had not yet started construction. Bolton & Menk performed a wetland delineation to identify the existing wetland boundary and type for the wetland in River's Bend Park that currently receives stormwater runoff from the 38-acre catchment. The LRRWMO reviewed the wetland delineation report and issued permit #24-21 on August 15, 2024, approving the revised wetland boundary and type. On August 12, 2024, the plans and specifications prepared by Bolton & Menk, Inc. were approved and advertisements for bids were authorized. Bids were advertised in QuestCDN, the electronic bidding platform utilized by the City of Ramsey for all improvement projects, and in the Anoka Union Herald on Friday, August 16th, and again on Friday, August 23rd, 2024. Five (5) bids were received, opened and tabulated on September 6, 2024. Douglas -Kerr Underground, LLC of Mora, Minnesota, submitted the lowest responsible total bid in the amount of $899,653.31 for construction of said improvements in accordance with the approved plans and specifications and advertisement for bids, and was awarded the construction contract on September 24, 2024. On September 19, 2024, the LRRWMO reviewed and approved the erosion control / stormwater permit for this project (LRRWMO Permit #24-26). Construction is now substantially complete but before the Anoka Conservation District will release grant funds the City must enter into the attached Natural Resource Improvement Grant Agreement that commits the city to specific operational and maintenance activities to ensure the long-term success of the stormwater improvements. Upon execution of the agreement a copy of the final construction plans (attached) will be attached to the agreement under Exhibit C - Porject Design. Staff reviewed this agreement and have no concerns with the terms and conditions included therein. The City Attorney reviewed the agreement and approved it as to legal form. Time Frame/Observations/Alternatives: Alternative # 1 - Motion to adopt Resolution #24-357 approving a Natural Resource Improvement Grant Agreement with Anoka Conservation District for Improvement Project #25-01, Rivers Bend Regional Stormwater Improvements.
