Zoning File #1411 September 1, 1989 Page 2 of 9 Roads/Future Access The interior plat road has been designed as a through road. Outlot A will be developed connecting to Leaf Street. There shall be a stop sign at the intersection of Outlot C and Outlot B in order zo discourage speeders that may use this road as a bypass. If Planning Commission feels it more appropriate Outlot R can be redesignated as a continuation of Outlot C and the cul- de-sac be redesignated as Outlot B. This will discourage any critics of the plat from assuming the City would have to grant a length variance for the plat road. Outlot A has been repositioned to north exiting now to a dry area and away from the wetlands to the south and east. Future access to the south of the major wetland on the east side of the property was discouraged because it would be too close to the Fox Street roadway. The roads have all been platted at the required 50 foot width with 100 foot diamate. cul-de-sacs. Please review the road plans Exhibits Y. The road shall be designed per Urban Road profile 28 foot minimum paired width to the inside edges of the curbing. Curbs and gutters will be provided. The applicant will be responsible for selecting three road names one for the major thru road and two for the cul-de-sac roadways. Please refer to your earlier exhibits in your pa<:'_at for your June meeting that showed the ownership patterns of the properties to the east. Note also that the plat road has been moved 26 feet from the wetland along the east side of the property. Wetlands/Watershed There are five basic watersheds that make up the property. Refer to Exhibit W. Unfortunately we do not have a large size map for Planning Commission's review, but a larger scaled copy will be availalbe at your meeting. Mr. Gronberg will also be present to present the drainage plans for the plat and -answer any questions members may have. Watershed 1 as shown on your map in southwest corner of the property predominately drains to the west via an open drainage way through the Stei:Aow Addition and out to Stubbs Bay. A berm at the 967 elevation along the south side of the pond inhibits drainage up to 967 elevation overflow drains to the culvert in the southwest corner and then eventually to Maxwell Bay. Drainage from the roadway based on the design and grade at the curve of the road brings water to the southwest corner culvert also. I am told by property owner to the south that this drainage design creates erosion problems on his property. Staff has asked Mr. Gronberg if the use of that culvert could be discontinued and what the impact would be on the drainage to the west. Mark Gronberg said that filling would be necessary to provide the re-channe-lization of the collection area now to the northern culvert. The request was feasible and could be considered.
