SEPTEMBER 7, 2010 CITY COUNCIL MEETING AGENDA ITEM
APPROVE COST -SHARE APPLICATION, CONTRACT, AND OPERATIONS AND
MAINTENANCE PLAN WITH DAKOTA COUNTY SOIL AND WATER CONSERVATION
DISTRICT TO INSTALL ROCK CRIB STORMWATER RETROFIT
Proposed Action
Staff recommends adoption of the following motion: Move to approve Cost -Share Application,
Contract, and Operations and Maintenance Plan with Dakota County Soil and Water Conservation
District (DCSWCD) for the installation of two rock cribs at the old Public Works Facility.
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.

OPERATION AND MAINTENANCE PLAN
Project / Landowner: Rock Crib at Lakeville Old Public Works Date: 8 -].0 -2010
Address: 7777 214 Street W. 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.
