ponds which ultimately outlet to a natural wetland adjacent to Trott Brook on the western edge of the preliminary plat. The first location is approximately 200 feet east of the Park trail on the western boundaD, of the plat, and the other is at the intersection of Royal Road (159th Street) and 162nd Lane N.W. These two drainage systems are acceptable as proposed. A third drain for the plat consists of existing catch basins on Royal Road (159th SrreeI) located approximately 150 feet south of the southern border of the plat. These catch basins discharge to a Iow area on the east side of the street which has no apparent outlet. Also a series of ponds are proposed west of the street which ultimate)v drain to the Trott Brook wetland. This catch basin requires street runoft~ to travel a distance of over 1,000 feet before reaching this catch basin. This distance should be reduced to less than 700 feet This might be accomplished by providing catch basins at the intersection of the southernmost cul-de-sac with Royal Road. It would also be desireable to provide an outlet for this low area through the proposed series of ponds across the sn-eet on the west side of Royal Road. If no such outlet is provided, an analysis should be prepared by a registered engineer which would establish the elevation at which a 4 inch precipitation event would innundate the low areas under frozen pound conditions. The plan should also be revised to show the location of silt fence during grading and erosion control during construction. Impact on adjacent land uses: It is estimated that Lots 16 through 21 of Block 2 abut Armstrong Kennels. As in Nor~. 'fork Oaks Addition, the developers are prepared to impose buffer zones on these tots and put buyers on notice that the kennels and their related activities exist. Pedestrian Transportation: Staff has determined that a transportation link is necessary between the mails in Northfork and Woodlawn Estates to the east_ The development a~eement shall require the developer to rough grade this transportation link. The lc}cation of this n"'ansportation link is preferred to follow along the backyards of lots 5 through 13 of Block 2. Tree Preservation and Planting Plan: The developer must submit a Landscape Plan as an addendum to the Grading Plan. This plan should identify existing tree ~owr. h that uill be preserved during all cons=-uction and the new planting of one 2-inch diameter tree, of an approved species, in the front yard of each lot. The developer should contact Parks and Utilities Coordinator Mark Boos at 427-!74i or 427-1410 to make a.rra.ngements for the sub~,~r',.al of the requS-ed Landscar~e Plan. No grading will be allowed undi this recmirement is fulfilled. · 'r ,= ,~ ' Janum-,, ~ ~ r,;,,~,,~,,o Co.?x-nission wS! bz m~eun~ a: 7:30 ~.m.. on ,u~ma~ ~, i995 to consider yoz r~ues: for preEm~mD' piar approv~ o~ No~ork O~s 2nd .~omno~. i: ~ imooF~nt that you, or yom- representative, bz pr:szn: ar the mee0mg to ~nswer ~ny questions ~qa: may ~qse.
