• • Mr. Smyser Oct. 1, 03 Pg. 2 Item 14 — Water - related Land Use Management District The majority of Wards Lake is within the Regional Park Reserve, resulting in a regional interest to protect the water resource. The EAW indicates the minimum lot size will be 20,000 square feet, the minimum lot width 80 feet, and the structure setback 150 feet. These requirements are significantly less that the statewide Minnesota Department of Natural Resource minimum standards for a Natural Environment classified lake. The statewide minimum standards for a non - sewered natural environment lake are: 200 feet lot width, 80,000 sq. feet minimum lot size, and 150 /150 sewer /structure setback. The statewide minimum standards for sewered natural environment lake are: (Assuming that sewer was feasible and approved by the City) - 125 feet lot width, 40,000 sq. feet minimum lot size, and 150 structure setback. Council staff suggests that the City give further review to the standards being applied to this site in relationship to the recommended state standards. Without the planned unit development designation, the proposed project would be subject to the City's shoreland ordinance. Item 16 — Erosion and Sedimentation The EAW identifies (hay) bale, checks (Figure 12) as one of the methods proposed to be specified for use as a temporary erosion control measure during construction grading on the proposed project. The Minnesota Pollution Control Agency (MPCA) currently considers hay bales to be generally ineffective in controlling erosion and sedimentation and no longer recommends using hay bales. Other options may be, checked dams of rock, staked heavy duty silt fences with large pore sizes, temporary retention ponds, and/or heavy temporary mulching on side slopes (followed by immediate re- vegetation) in lieu of hay bales. Council staff recommends altering the specifications for this (and other similar) proposed project(s) to conform to these revised MPCA erosion control recommendations. This concludes the Council's review of the EAW. If you have any questions or need further information, please contact Christy Stark, principal reviewer, at 651- 602 -1750.
