Terre De Ueau - Sketch Plan Page 5 Density The proposed development would have a gross density of 1.5 units per acre and a net density of 2.5 units per acre, but the final calculation must be provided by the applicant with the preliminary plat. The City's Comprehensive Plan allows up to 4 units per acre with a PUD in the R-3 zoning district. Building Materials/Design The applicant did not provide building elevations or material samples at this time. Although the applicant stated that the Villas and Detached Townhomes would be maintenance provided, they did not submit details about association maintenance with this application. These items would need to be reviewed as part of the preliminary plat application. Wetlands The site contains approximately 35 acres of wetlands of Various qualities. The majority of the wetlands are jurisdictional to the State Wetland Conservation Act (WCA), but a small portion in the northeast corner of the site is identified as a public waters and regulated by the Minnesota Department of Natural Resources (DNR). The wetlands have been delineated within the site and Technical Evaluation Panel (TEP) has approved the delineation. The applicant will need to work with the TEP and the City Water Resources Engineer as the project moves forward to obtain any necessary permit(s) related to the wetland delineation, if impact or mitigation is proposed with the development. Floodplain A portion of the property is located within the floodplain district. The FEMA Floodplain map designates the area around the private ditch on the site as a "Zone A" area A ith the regulatory floodplain elevation of approximately 930 - 931. It is likely that the proposed site grading will impact the floodplain and the applicant will need to work with the City Water Resources Engineer during the permit process to mitigate any proposed impacts. Grading/Drainage There is a private ditch that runs through the site. The groundwater within the site has the potential to be relatively high which will require that additional analysis to be completed before finalizing the grading plan and low -floor elevations. Ponding for water quality and rate control will be required on site in compliance with City standards. In addition, the applicant has indicated that the stormwater ponds will be used for irrigation through a water reuse system.
