MFS Consulting Engineers & Surveyor, DPC (MFS) provided professional land surveying services for the site located on Central Park Avenue, between Midland Terrace and Inwood Street in the Yonkers, New York.

Yonkers, New York

Project Details

In the absence of project control supplied by the client, the horizontal control was established in the field by GNSS RTK observations at least two primary control points. Additional control points were set and located by conventional traversing procedures. The horizontal control was tied to the appropriate State Plane Coordinate System NAD83, US Survey Feet. The vertical datum was tied to NAVD88 either by a level run from known NGS Vertical benchmarks or GNSS RTK observations.

MFS field personnel performed the necessary fieldwork to locate evidence of property lines, including, but not limited to property markers, monuments, crosscuts, fences, walls, building, and curb lines to assist in determining the boundary lines. MFS obtained, via web-based land records research, current deeds of the properties that were within the survey area scope of work. For properties abutting state or county roads, MFS obtained right-of-way documents for the proper agency.

MFS performed a topographic field survey to locate the apparent accessible above-ground physical features, such as but not limited to; buildings, curbs, edge of pavement, drives, striping, sidewalks, fences, walls, utility/light poles (with enumeration), signs, trees (greater than 6 inches in diameter), and tree lines. First floor/garage floor elevations were determined at doorways. Cross-sections of paved surfaces were surveyed at a minimum of 50’ intervals and at low/high points. Spot elevations were obtained at a spacing sufficient to develop contours at an interval of one foot. Breakline features such as top/bottom of curb, edge of pavement, top/bottom of slopes/swales/banks/walls, etc. were located. At waterways, the surveys extended to the edge of water at low tide.

MFS located the apparent accessible surface utilities’ surface hardware, such as manholes, catch basins, trench drains, valve covers, utility/light poles, hydrants, etc. MFS located any apparent utility mark-out visible at the time of the field survey that was marked out by others. For storm drains and sanitary sewers, MFS obtained measurements to determine inverts and pipe sizes at accessible manholes and catch basins.

Subsurface utilities such as water, gas, electric, and communication were depicted based on surface features and available mapping. The depiction of subsurface utilities was based on the location of surface structures and record mapping.
