, . , Preliminary Plat and Site Plan Review: Ebony Woods August 31, 2006 Page 2 of6 should include required information listed in 9.03.08 (Site Plan) of City Code, in addition' to any application information listed in the Overlay District regulations. The District requireme~ts state that the project shall be developed as a Planned Unit Development, shall preserve 50% of the land as open space, and. restrict impervious (rooftop and pavement) to 25% of the lot area (or up to 35% with a Conditional Use Permit). It is also noted that the maximum structure height in the Overlay District is 35 feet. If this project goes forward, compliance with the Mississippi Overlay District regulations will have to , be demonstrated on the preliminary plat and site plan. 4. Lot Size and Dimensions: The proposed twinhome lots are all 40 feet in width with the exception of Lot 6, which is 44 feet wide. TheR-2 Residential District requires 50-foot lots for twinhomes. A reduced lot width may be permitted as part of the PUD, if approved by the City Counci~. All proposed lots exceed the minimum lot size for twinhomes of 7,000 square feet. 5. Density: The subject property is approximately 1.1 acres in size. The Medium Density Residential designation allows for 3-7 units per acre. The sketch plan proposes 6 units which equates to a density of 5.5 units per acre. This density is acceptable if the comprehensive plan amendment and rezoning requests are granted. 6. Setbacks: The R-2 District requires a front yard, side yard, and rear yard setback of 30 feet, 10 feet, and 30 feet r~spectively. All the proposed units meet these requirements. This parcel is over 800 feet from the Mississippi River. 7. Open Soace/Impervious Surface Requirements: The draft Mississippi River Overlay District regulations require a minimum of 50% open space and a maximum of 25% impervious surface. 35% impervious surface is permitted with a CUP. The site plan shows 71 % open space in the yard areas for the twinhome units, resulting in 29% impervious surface. As the Overlay District requirements are not yet effective, staff feels the submitted plat -_ meets the intent of the open space and impervious surface requirements. It should be noted that current river regulations limit impervious surface to 30%, which the plan meets. 8. Architectural Standards: The R-2: Medium Density Residential district requires the following architectural requirements: 1) The front fa<j:ade of structures shall consist of a minimum of 35% brick, stone, or stucco. 2) A minimum of three colors shall be used for each structure. Also, an effort should be made to vary colors among structures. A color palette is required as part of the site plan approval and building permit approval process. 3) All structureS shall include at least 2 of the following items: a. Articulated/cantilevered fa<j:ade b. Dormers c. Articulated roof line 10
