Overview Through the DCSWCD cost -share program, staff is looking to have two rock crib structures installed on the north side of the existing parking lot at the old Public Works Facility on Hamburg Avenue. Currently, the water from the site discharges directly to South Creek, a designated trout stream and tributary to the Vermillion River. The rock cribs will be designed to cool the temperature of the stormwater runoff from the site before it discharges. The temperature reduction is important for the health of the trout. The rock cribs will reduce thermal impacts from 14,300 square feet of existing parking lot and 4,600 square feet of existing roof top. This site will also serve as a demonstration site for the Vermillion River JPO's 319 Thermal study to measure the effectiveness of rock cribs as thermal best management practice. The rock cribs will have design variations from other rock cribs to compare their relative effectiveness. The total estimated cost of the project is $15,042. The grant is a 39/61 percent cost share grant where the City's contribution will consist of in -kind services for design assistance and construction administration. The and value is also included as part of the city's match. The remaining cost of the project ($9,138) will be provided by the DCSWCD. There will be no cash contribution required by the city for the construction of the rock cribs. Primary Issues to Consider • The agreement requires the City to maintain the rock cribs for a minimum of ten years. The maintenance cost is very nominal.

Lakeville, MN 55044 OVERVIEW This Project was designed to provide many long -term benefits for natural resources and wildlife habitat. The expected minimum performance life of conservation practices are at least ten (10) years. Providing good stewardship and carrying out an operation and maintenance program including periodic inspections can increase it's life span many times over. The following general recommendations will help you in performing adequate operation and maintenance for a variety of conservation practices. GENERAL RECOMMENDATIONS • The Cost -Share Contract prohibits the removal and/or modification of the practice for ten (10) years from the date of completion without prior written approval by the Dakota SWCD. • Report any observed active erosion, land disturbances or other unusual conditions that may affect the intended performance of the practice to the Dakota County SWCD right away. Call (651) 480 -7777 • For bioretention areas, periodic removal of sediment and debris is necessary to maintain the effectiveness. The cleanout intervals may vary depending upon the volume of sediment that has accumulated. Avoid compaction of the underlying soil. • Maintain vigorous growth of desirable vegetative coverings. This may include reseeding, fertilization, weeding and /or controlled application of herbicides when necessary. Periodic mowing may also be needed. • Repair areas of active erosion or channel or slope failure immediately. Additional measures to prevent reoccurrence may be necessary. Contact the Dakota County SWCD for technical assistance. • Prevent unauthorized foot traffic, motorized vehicles or livestock entry. • Immediately repair any vandalism, vehicular, or livestock damages. • Make sure all structure drains are functional and soil is not being transported through the drainage system. The screens and/or rodent guards shall also be kept in place. • Eradicate or otherwise remove all rodents or burrowing animals and repair any damage caused by their activity.
