The general rules are: <br /> 1. Where water has always drained from one property to another, drainage may <br /> continue but flow must not be increased. <br /> 2. New runoff from house and drive must be kept on the property. <br /> 3. As always, water runs downhill. <br /> To meet this goal, you were required to have drainage plans approved by the City at the time <br /> of construction. Your builder, Lecy Construction, devised a combination of an area drain and <br /> a blacktop drainageway to direct new runoff from your house and driveway into your front <br /> yard. This combination was never intended to handle the large amount of runoff from further <br /> west of your house. <br /> The City tried to encourage the builder at 1030 Tonkawa Road to delete their basement garage. <br /> We felt they would only exacerbate an already difficult and historical water problem on that <br /> lot. The builder was convinced that his engineer could design an appropriate boulder wall to <br /> deal with the situation. <br /> Some degradation of your blacktop spillway has occurred. Probably due to ground settlement, <br /> water now flows off the side and toward your neighbor's wall. This drainage should stay on <br /> your property. Either a curb or some fieldstones along the south edge of the spillway and a <br /> little landscaping would probably correct this situation. <br /> Telephone (612) 473-7357 • FAX 473-0510 <br />
