Wetlands & Storm water Management The City has a preliminary agreement with the applicant to incorporate the wetland and a proposcd storrnwater treatment pond into the stonnwater management system for the Ridgewood ncighborhood pavement management program. The wetlands and treatment pond would be included in an easement that would be dedicatcd to and maintained by the City. Much of Lot 2 and a portion of Lot 3 would not be buildable due to thc cascments placed on the property; however, there would be sufficient room at the northern parts of cach lot to accommodate a single family homc and garage. Plan Cl in the attachments to the Planning Commission report show the proposed easement lines. Plan G 1 shows the proposed building pads. To create the building pads shown in Plan Gl, approximately 834 square feet of the n0l1hernmost segment of the wetland and two small segments at the northeastern part of the wetland are proposed to be fillcd. To mitigate the wetland loss, thc City will expand the wetland along the southem edge to compensate for the loss ofwetJand on the northern side. For every one square foot of wetland removed, thcre will be at least two square feet replaced. Additionally, approximately five thousand cubic yards of excess fill from the road reconstruction project will bc used for fill in the wetland and to provide a more stable base outside that is well above a potcntial flood area in the buildable area for thc future homes on Lots 1 and 2. The preliminary agrccment with the property owner for the easements and storrnwater management docs not obligate the City to approve the preliminary plat proposal if the proposal is unable to meet the requirements of the Subdivision Code. The Rice Creek Watershed District (RCWD) is the responsible governmental unit for reviewing wetland filling and grading. The applicant, with assistance from the City, has submitted the required documents to the RCWD. Due to the timing ofthe RCWD review process, the decision on the permit was not available in time for the rclease of this packet. The applicant will necd to submit a copy of an approvcd pemlit from the RCWD before the Final Plat is approved. Since the wetland filling is, in part, related to a City project that involves treating stormwater before it entcrs Lake Johanna, it is quite likcly that the application to thc RCWD will be approved. While wetland filling is usually a causc for concern, this project will help improve the overall storm water situation in this neighborhood and will increase the quality of the water that enters the lake. Recommendation Thc Planning Commission reviewed Plmming Casc 06-026 and unanimously recommends approval of thc preliminary plat based on the following six findings of fact: Zoning Ordinance Findings: I. The preliminary plat proposal meets or exceeds all of the requirements of the underlying R-l Zone, including minimum lot size, lot width, and lot depth.
