07-3302 9 July 2007 Page 3 of 3 Road Improvements and/or Easements Needed The City requires standard perimeter, drainage and utility easements around all property boundaries in the plat as well as Conservation and Flowage Easements over the delineated wetlands. Establishment of wetland buffers and buffer setbacks will be triggered for the lots containing wetlands. Stormwater and Drainage Improvements As no new lots are proposed the property will not be subject to the Stormwater and Drainage Trunk Fee. Utility Locations and Availability The property would be served by septic systems and private wells. Willie Gibbs has reviewed the submitted septic designs for each lot and deemed them acceptable. His memo is attached as Exhibit D. Private water supply wells shall be setback 3' from structures and 50' from septic systems. City Engineer Comments The City Engineer has provided comments which are attached as Exhibit C. Wetlands on Site and/or Impacted One wetland has been delirieated on the property and the appropriate buffer widths and setbacks have been indicated on the survey. The Minnehaha Creek Watershed District (MCWD) has conducted the wetland delineations provided as Exhibit E. Portions of the delineated wetland boundary appear to be exceeding the actual required limitation, particularly in the area where the alternate septic drainfield is located. This does not need to be revised as a generous wetland delineation serves as an additional protective buffer for the wetland. As mentioned earlier in this report, the City will require a Flowage and Conservation Easement and the establishment of buffers for the wetland designated on the site. The applicant is advised to avoid any impacts to wetland which can be avoided by proper site layout. The MCWD is the City's LGU for administration of the Wetland Conservation Act rules. Shoreland Regulations As a protected creek(Wolsfeld Creek) runs through the property, shoreland regulations apply. A 75' structural setback from the creek is required as well as hardcover regulations up to the 300' setback. Issues for Discussion Does the Planning Commission have any issues for discussion? Staff Recommendation The proposed subdivision appears to meet the City's ordinance standards for development in the RR-1B zone. The applicant should revise the alternate septic drainfield area prior to placement on the City Council agenda to eliminate any encroachment into the delineated wetland boundary. Planning staff recommends approval of the subdivision. 3
