The site is located on Lot 7, Block 3 of The Meadows at Redwood P.U.D. A copy of the approved grading and drainage plan for the subdivision is included as Exhibit B. Per the flood insurance rate map (Exhibit C), the lot is located within Zone X. Zone X is defined as an area of minimal flood hazard and does not have a base flood elevation associated with it. The existing lot is partially developed with a garage and concrete driveway and surrounded by fully developed residential lots. The total existing impervious area is 1,279 square feet (sf) or 21 %. Despite the approved grading and drainage plans proposing the lot to drain to the south, the majority of the site currently drains to the north and has a high point located approximately 20 feet north of the southeastern property corner. The proposed lot improvements will allow for stormwater to drain from the rear of the home to the front via a drainage swale designed at a minimum 1°/o slope. The impervious area has increased 1,289 sf to a total of 2,568 sf imperviousness, which is 42% of the total lot area. The Urban Drainage and Flood Control District recommends the average imperviousness of 45% for single-family lots that are 0.25 acres or less (Exhibit D), which is comparable to the proposed lot improvements. It is my professional opinion the proposed grading and drainage design has improved the existing IoYs drainage patterns, adheres to the intended development plan approved in 1986, and prevents adverse stormwater impacts to the adjacent properties. �i Q � � '�t � �� C� �'1.
