Carolina 27699 FbIN Re S West Street Utility Improvements — NWP 18 PCN Submittal W &R Project #02050400 14 Dear Mr Brown and Mr McMillan On behalf of the Town of Cary we are requesting authorization from the USACE to use NWP 18 for 0 002 acres of permanent impacts to jurisdictional streams (27 lf) for the replacement of existing undersized stormwater pipes to alleviate issues with flooding We are also requesting 401 certification as well as buffer authorization for 826 sq ft of permanent buffer impacts and 5 382 sq feet of temporary buffer impacts associated within construction of the proposed project The project is located on S West Street south of the intersection of S West Street and Dry Avenue in Cary Wake County (Latitude 35 7818 °N Longitude 78 785947 0W) The project is located in the Neuse River basin and onsite waters drain to MacGregor Lake / Swift Creek The Water Quality Classification for MacGregor Lake is WS III NSW and the Stream Index Number is 27 43 2 2 The cataloging unit for the site is 03020201 Proposed Project The proposed project consists of the replacement of the existing undersized 30 stormwater pipe which conveys water from the UT to Swift Creek beneath S West Street As a result of the existing pipe being too small to convey storm flow the residences and S West Street flood during periods of high flow In order to alleviate the flooding issue the existing 30 stormwater pipe will be replaced with double 36 pipes which will convey stormwater at peak flows without flooding The installation of the double 36 pipes at Impact 1 will require excavation of the stream bank to widen the stream to accommodate the double pipes and allow flow into both pipes Rip rap will be placed within the stream channel and on the banks to stabilize the disturbed areas as well as prevent undercutting of the pipe and road as well as prevent erosion of the stream banks At Impact 2 the stream bed is bedrock Therefore only the stream banks will be armored with rip rap to prevent erosion 1410 Commonwealth Drive I Suite 1011 Wilmington NC 28403 1 tel 910 256 9277 1 fax 910 256 2584 www withersravenel com I License No C 0832 WITHERS 6C RAVEN EL ENGINEERS I PLANNERS I SURVEYORS Proposed Impacts The proposed impacts consist of o 002 acres of permanent stream impacts (27 lf) and 826 sq ft of permanent buffer impacts (Zi 826 sq ft) for installation of the double 36 pipes There will also be 5 382 sq ft (Zs 5 249 sq ft Z2 133 sq ft) of temporary buffer impacts as a result of disturbance during construction activities Avoidance and Minimization Due to the location of the existing 30 stormwater pipe and utility easement as well as the nature of the project impacts to streams and buffers could not be avoided Both Zone 1 and Zone 2 of the buffers currently consist of maintained grass associated with Heaters Park and the residences east of S West Street Therefore the project will not require clearing of woody vegetation within the buffers Upon completion of the project the temporarily impacted buffers will be seeded with a grass seed mix to provide stabilization Mitigation Because the proposed permanent impacts are less than o so acres and the proposed permanent stream impacts are less than 150 if we do not believe that mitigation should be required for stream impacts Since the placement of rip rap on the stream banks is for the purpose of stream stabilization and stream stabilization is identified as an allowable use no buffer mitigation is proposed The current request is for o 002 acres (27 lf) of permanent impacts to jurisdictional streams 826 sq ft of permanent buffer impacts and 5 382 sq ft of temporary buffer impact (see the attached maps and PCN for details) Please feel free to call if you have questions or require additional
