Wiles Mensch Corporation – DC (WM) provided civil engineering services for the development of a 1.4 mile stretch in a Northeast neighborhood of Washington, DC. The project area spans from 2nd Street NE to 15th Street NE, including perimeter streets of Stanton Park (C Street, 4th Street, and 6th Street). The project serves to reduce the number of general purpose lanes from four to two along Maryland Avenue, between 3rd and 4th Streets NE, and between 6th and 15th Streets NE. Left turn lanes were added where left turns are permitted, as well as bike lanes. Full time parking will remain on both sides of the street. Traffic pattern changes were proposed at 7th Street/D Street/Maryland Avenue to remove north/south motor vehicle through traffic on 7th Street. The design also includes modifications to the existing medians and curbs to improve pedestrian safety by reducing vehicle turning speeds and pedestrian crossing distances.
WM’s core responsibility for this project was to integrate low impact development features in the streetscape. This includes utilizing the appropriate stormwater management techniques for streetscape and roadway areas. The public area was developed to have 6’ wide sidewalks and a 4’ wide tree planting area.
WM’s scope of services also included coordination with DDOT and UFA for special tree protection, as well as with DOEE for stormwater management in the public right of way. All designs and submissions were made in accordance with the standards outlined in the DDOT Design and Engineering Manual.
