• • Wetlands Wetland delineation was completed by Kjolhaug Environmental Service in October 2004 and located by Passe Engineering per plans of Marshan Meadows. Per Rice Creek Watershed District letter dated November 7, 2013, a new delineation is not required since no impacts to the wetlands are proposed. Floodplain The FEMA Floodplain Zone AE is located on the preliminary plat. The 100 -year regulatory flood elevation on the property is 887.0 feet according to RCWD. No impacts to the floodplain are proposed. Shoreland Management Overlay District Land located within 1,000 feet from the ordinary high water level of a public water is subject to the Shoreland Management Overlay District. The proposed subdivision abuts Marshan Lake which is classified as a Natural Environment Lake. The Shoreland Overlay District regulates lot area, lot width and impervious surface. The proposed subdivision meets those criteria as noted above in the report. The Shoreland Overlay also regulates structure setbacks. A 150 foot setback from the ordinary high water level (OHWL) is required for all principal and accessory structures. This includes decks, patios and sheds. This setback extends into Lot 2 which limits the buildable area of that lot. It is important to note the difference between the following definitions: Buildable Area. The portion of a lot remaining after yards have been provided. Buildable Land, Contiguous. Land area occurring within the property lines of a parcel or lot excluding wetlands and /or water bodies. The buildable area of Lot 2 is approximately 3,000 square feet. The buildable land area is 20,116 square feet. It is also important to note the permitted front setback in the R -2, Two Family Residential District is 25 feet. The zoning ordinance was amended in 2012 (Ord. 03 -12) which decreased the front setback from 30 feet to 25 feet. Variance The Shoreland District references a front setback of 30 feet which was consistent with the underlying zoning district; however, when the R -2 zoning ordinance was amended to 25 feet, the Shoreland District was not amended to reflect the change in the front setback. A variance is required from the Shoreland Overlay District.
