• • Planning & Zoning Board July 9, 1997 Page 6 Mr. Johnson answered, 7+ acres. If it completely fills, it will be between 9.5 and 10 acres. Two smaller ponds will also be built. Mr. Dunn asked if there is any danger that the runoff will move in an easterly direction that would impact the row of homes in the Second Addition. Mr. Johnson explained that there is a culvert between Lot Nos. 20 and 21 and in the middle of the block between Palomino and Appaloosa. The culverts are 36 inches to 42 inches in height and flow from west to east. All of the runoff from 250 acres upstream of the ditch can be stored with the outlet discharge rate of less than 1 CMS. Increased capacity is provided to preserve wildlife habitats from the rapid rise and drop in elevation. The level of the pond will vary a foot or two unless there are downstream conditions to affect it. The lowest floor elevation of the pond is 2 feet above 898. Mr. Robinson questioned the feasibility of adequate drainage of the property to the north. Mr. Johnson stated that the wetland would need to be drained and the water table lowered. Even though there is dry wetland, the soil meets wetland criteria. To improve drainage, the developer proposes to improve drainage maintenance and make sure properties are not exposed to flood risk. He believes the plan meets or exceeds that objective. He added that the developer is working closely with the watershed district and does not anticipate any problems with approval. Mr. Dunn asked if the developer has a tree preservation policy. Mr. Johnson stated that the lots with trees will be treated selectively, so that only trees necessary to build a street will be removed. Home buyers will be able to select how a house is set on a lot with respect to the trees on that lot. Mr. Uhde, Developer, stated that the Second and Third Additions were approved by the Board without formal approval from the Metropolitan Council on the MUSA expansion. The approval from the Board was contingent upon the MUSA expansion. Therefore, he is not certain what concern there is for precedent. Grading is an issue for this construction season, and a grading permit has been available before preliminary plat approval in the past. He requested the Board to reconsider its position and consider approval of the application at this meeting. The longer the project is delayed, the higher the cost and he would like to keep the lots affordable. Mr. Dunn asked if Mr. Uhde met with the neighbor who expressed concern about privacy.
