Improvements to Mount Vernon Avenue West Orange, New Jersey PURPOSE OF CONTRACT Matrix New World Engineering (Matrix) was engaged by the Township of West Orange Department of Public Works, Division of Engineering, to provide surveying and civil engineering services for the roadway improvements to Mount Vernon Avenue, a sloped dead-end residential street located within the Township limits. These improvements extend from Pleasant Valley Way to Garfield Avenue with a street length of approximately 925 feet. An existing drainage swale on Roosevelt Avenue (paper street) is located approximately 150 feet south from Mount Vernon Avenue and was connected to the Mount Vernon Avenue storm system. Matrix surveyors provided right-of-way, existing conditions, and topographic mapping established the centerline of the existing right-of-way utilizing Township filed maps, deed, and tax maps for the various properties along the roadways. Matrix civil engineers provided construction documents plans to address the various improvements. The pavement was in various stages of distress. Curbs were intermittently damaged or tilted, with inconsistent curb heights. Sidewalks also had sections needing repair or exhibiting uneven grades due to settlement or heaving. Based on review of the topographic survey, existing Township documents, and field investigations with the town engineer, we identified areas where full depth pavement replacement is warranted, with the balance of the areas requiring milling and repaving. All concrete curbs were replaced with Belgium block stone, with elevations adjustments made to keep a consistent look throughout the roadway. Grade impacts to residential driveways were minimized with replacement of those sections located within the towns ROW. At the top of the roadway slope, Matrix designed a hammerhead vehicle turnaround section for ease of motion for the town’s sanitation and snow plow trucks. Adjacent to the turnaround diversion swales were designed to capture stormwater runoff coming off the steep sloped wooded areas and to keep from flooding out resident’s backyards. Matrix sized a culvert to replace the existing drainage swale along Roosevelt Avenue and tied it directly to the Mount Vernon Avenue storm sewer system. The area surrounding this swale was then filled and graded with a small diversion berm/ditch created to capture the small amount

nue and tied it directly to the Mount Vernon Avenue storm sewer system. The area surrounding this swale was then filled and graded with a small diversion berm/ditch created to capture the small amount of surface runoff from flowing into the adjacent property. In conjunction with the preparation of construction plans, Matrix prepared the construction specifications and project cost estimate.
