I I I I I I I I I I I ! ! I I ! I I I o ponds which ultimately outlet to a natural wetland adjacent to Trott Brook on the western edge of the preliminary plat. The first location is apprgximately 200 feet east of the Park trail on the western boundary of the plat, ~and the other is at the intersection of Royal Road (159th Street) and 162n):1 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 (159ih Street) located approximately 150 feet south of the southern border of th~ plat. These catch basins discharge to a low area on the east side of thc s~rcet which has no apparent outlet. Also a series of ponds are proposed west ~of the street which ultimately drain to the Trott Brook wetland. This catcl~ basin requires street runoff to travel a distance of over 1,000 feet befox~e reaching this catch basin. This distance should be reduced to less than ~00 feet. This might be accomplished by providing catch basins at the inteniection of the southernmost cul-de-sac with Royal Road. It would also be d~_sireable to provide an outlet for this low area through the proposed senea of ponds across the street on the west side of Royal Road. If no such outlei is provided, an analysis should be prepared by a registered engineer whic~ would establish the elevation at which a 4 inch precipitation event woul~t innundate the low areas under frozen ground conditions. The P. lan should also be revised to show the location of silt fence during grading and erosion control during construction. 1, Impact on adjacent land uses: It is estimated that Lots 16 through 21 of Bl~ck 2 abut Armstrong Kennels. As in Northfork Oaks Addition, the developers are prepared to impose buffer zones on these lots and put buyers on notice that the kennels and their related activities exist. PedeStrian Transportation: Staff has determined that a transportation link i$ necessary between the trails in Northfork and Woodlawn Estates to the ea~st. The development agreement shall require the developer to rough gradei this transportation link. The location of this transportation link is prefe~ed to follow along the backyards of lots 5 through 13 of Block 2. Tree iPreservation and Planting Plan: The developer must submit a Land~4cape Plan as an addendum to the Grading Plan. This plan should identity existing tree growth that will be preserved during all construction and tt/e. new planting of one 2-inch diameter tree, of an approved species, in the frtJnt yard of each lot. The developer should contact Parks and Utilities Coor~nator Mark Boos at 427-1741 or 427-1410 to make arrangements for the submittal of the required Landscape Plan. No grading will be allowed until this requirement is fulfilled. The Planning.' Commission will be meeting at 7:30 p.m. on Tuesday, January 3, 1995 to consider your request for preliminary plat approval of Northfork Oaks 2nd Addition. It i~ important that you, or your representative, be present at the meeting to answer any~questions that may arise.
