Environmental Board <br />February 23, 2022 <br />Page 2 <br />APPROVED MINUTES <br />biological significance by the DNR due to a high quality colonial waterbird nesting <br />area. <br /> <br />A private ditch on properties lying north of Amelia Lake provides drainage for <br />approximately 340 acres to Amelia Lake. The ditch corridor and adjacent wetlands <br />are proposed components of the City’s parks, greenways, and trail system in the 2040 <br />Comprenhsive Plan. <br /> <br />Recently, there has been flooding in the ditch corridor due to limited maintenance and <br />failure of private culverts. <br /> <br />In an effort to evaluate long-term stormwater management options for this <br />subwatershed area, staff is proposing to develop an Amelia Lake Subwatershed <br />Management Plan/Feasibility Study in partnership with the Vadnais Lake Area Water <br />Management Organization (VLAWMO). The study will develop alternative concepts <br />aimed at enhancing water quality, preserving flood storage, and providing for <br />potential recreational and wildlife corridor features. <br /> <br />The partnership with VLAWMO will include a cost match for professional services <br />required to complete the feasibility study, with the City and VLAWMO each <br />contributing 50% of the cost, with the total cost not to exceed $30,000. City staff will <br />also be managing the consultant developing the study. <br /> <br />A Request for Services was sent to four qualified engineering firms. City and <br />VLAWMO staff reviewed the four responses and reached consensus that WSB and <br />Associates is the recommended firm for development of the study, based on their <br />experience with City drainage in the area and the overall strength of their proposal. <br /> <br />Highlights from the Scope of Work for this study include: <br /> <br />1. Four meetings and one site visit <br />2. Existing conditions review and summary <br />3. Survey of topography of the ditch, slopes, erosion, stormwater structures, and <br /> grades <br /> 4. Monitoring pollutant data for the lake <br /> 5. Water quality and drainage modeling <br /> 6. Surface water improvement options based on different ownership scenarios <br /> 7. Permitting requirements and funding options <br /> 8. Final Report <br /> <br />Mr. Parsons asked about the history of conservation work on the lake and if Art <br />Hawkins’ work had influenced or impacted the current project. <br /> <br />Mr. Sullivan mentioned the results of the work may be accounted for in the 2040 <br />Comprehensive Plan. <br />
