HAZEN AND SAWYER, p.c. 8- 11-V7 <br /> CONSULTING ENGINEERS <br /> 29i <br /> August 11 , 1987 <br /> Mr. Greg Szymik <br /> Orange County Planning Department <br /> 106 East Margaret Lane <br /> Hillsborough , NC 27278 <br /> Re : Proposal for Engineering Services <br /> Wildwood Subdivision Drainage Study <br /> Dear Mr. Szymik : <br /> Hazen and Sawyer, P .C . , is pleased to submit our proposal <br /> for a drainage study of the Wildwood subdivision in Orange <br /> County. Our proposal is based upon a field tour of the <br /> subdivision, discussions with various members of County staff , <br /> and review of pertinent interoffice correspondence relative to <br /> staff investigations of reported problems within the <br /> subdivision. <br /> Based on our tour of the existing subdivision , observed <br /> drainage problems at the site include the following: <br /> 1 . Roadside ditches with minimal to inadequate <br /> longitudal slopes . Very flat longitudal slopes are <br /> creating areas of standing water within the ditch <br /> section . In some locations , the elevation of the <br /> driveway culvert pipes appear to be contributing to <br /> the problem. <br /> 2 . Portions of the existing lots are in low lying areas <br /> with poor natural drainage . Reports of nuisance <br /> "springs" have been received from the property <br /> owners in these area. It is likely that the <br /> seasonal groundwater table in the low lying areas is <br /> at or near the surface of the ground for extended <br /> periods of time each year. Drainage improvements in <br /> such areas may provide some relief , but we suspect <br /> that this problem will continue to be a nuisance to <br /> at least some extent. <br /> 4300 GLENWOOD AVENUE • P.O.BOX 30428 • RALEIGH,NORTH CAROLINA 27622 (919)782-8333 <br /> RALEIGH.NC CHARLOTTE.NC • HOLLYWOOD,FL NEW YORK,NY <br />
