A Proposal for Lake Amelia Subwatershed Management Plan for the City of Lino Lakes | 3 <br />Task 7. Permitting Requirements and Funding Options <br />(36 hours $4,200) <br />WSB will assess each concept evaluated in Task 6 and <br />will identify the permitting requirements at local, state, <br />and federal level. Additionally, WSB will identify potential <br />funding sources and partnerships that can assist towards <br />implementation. Permits will likely be required for wetland <br />and floodplain impacts and for the CIty and VLAWMO. <br />Task 8. Final Report (48 hours $5,900) <br />WSB will first prepare and distribute a Preliminary Report to <br />summarize the improvement concepts, including the key <br />maps, figures, tables, and appendices containing the full <br />evaluation. The report will also include permitting needs and <br />funding options. A fourth meeting will be held to discuss <br />the report and determine whether any additional data or <br />clarifications are needed. WSB will collect feedback and <br />proceed with the preparation of the Final Report. <br />MT. OLIVET AND PARKERS LAKE STREAMBANK IMPROVEMENTS <br />SEPT 2020 – PRESENT | CITY OF PLYMOUTH AND BASSETT CREEK WATERSHED CREEK WATERSHED MANAGEMENT <br />COMMISSION (BCWMC) <br /> <br />WSB worked with the City of Plymouth and BCWMC to address erosion along two intermittent streams in the City. The goal <br />of the project at both sites, Mt. Olivet and Parkers Lake, was to slow the velocity of water through the channels and provide <br />permanent stabilization of the streambanks to reduce the pollutant loads to the downstream impaired water bodies. Multiple <br />techniques were employed to meet these goals including rock and log ditch checks, the installation of plunge pools, <br />regrading and widening the channel, native seeding, and hard armoring. <br />WSB completed hydraulic modeling using HEC-RAS 2D to determine the areas along the streambanks with the highest <br />velocities and shear stresses. Water quality was modeled to quantify the reductions in downstream Total Phosphorus (TP) <br />and Total Suspended Solids (TSS) loads. The project included approximately 0.67 acres of wetland restoration at the Mt. <br />Olivet project site and required significant coordination with the City of Plymouth, BCWMC, and other permitting agencies <br />and stakeholders. <br />REFERENCE: BEN SCHARENBROICH, WATER RESOURCES SUPERVISOR, 763.494.6354 <br />PROJECT EXAMPLES <br />WATERTOWN STREAMBANK FEASIBILITY STUDY <br />MAY 2021 - OCT 2021 | CARVER COUNTY WATER MANAGEMENT ORGANIZATION (CCWMO) <br />AND CARVER COUNTY SOIL AND WATER CONSERVATION DISTRICT (CCSWCD) <br /> <br />WSB teamed with CCWMO and CCSWCD staff to survey all streambanks along the South Fork of the Crow River within the <br />City of Watertown. The survey documented 19 properties with erosion issues ranging from minimal to severe. Working with <br />CCWMO staff, WSB developed a feasibility level stabilization plan for each site which favored vegetation-based stabilization <br />methods over hard armoring techniques and included a feasibility-level cost estimate. WSB developed estimates of sediment <br />loading from each site to quantity proposed water quality improvements and related them to the existing Total Maximum Daily <br />Load (TMDL) which is in place for the South Fork of the Crow River. Finally, WSB made quantitative assessments of the relative <br />instability of each site and the risk of no action if stabilization activities were not completed. <br /> <br />REFERENCE: TIM SUNDBY, WATER RESOURCES TECHNICIAN, 952.361.1816
