ECM provides engineering design services for preparing preliminary, advance check plans and final plans and specification in conforming to City of New Orleans General Specifications for Street Paving for the streets in the Lake Terrace Oaks- Group – C and Lakeshore Area Group – E projects simultaneously. This project is a part of a FEMA funded roadway capital improvement program for the City of New Orleans. Total construction cost of the entire project is $11.5 million. ECM is providing engineering design for these projects that include 20 city blocks of roadway including intersections. Work for roadway reconstruction included PCC paving, Asphalt paving, roadway intersections with handicap ramps conforming to current ADA standards, new sidewalks, driveways and subsurface drainage system, sewer line and water line design.  Reconstruction includes roadway removal, adding geotextile fabrics and aggregate base, grading and compacting, new paving with curb and gutter. 

ECM was responsible for coordination for topographic and subsurface utility survey, field verification of survey data; coordination with S&WBNO, Entergy, AT&T and other private utilities entities for providing location and depth of their utilities and including their information in the plan and profile sheets. ECM developed existing and proposed drainage area maps and hydraulic calculations using DOTD hydraulic software HYDR Programs for the tributary area, as well as prepared a preliminary roadway plan and profile with a coordinated drainage collection system. Hydraulic design calculations were performed to size drainpipes and locate the roadway inlets. 

The project included schematic design services to develop a conceptual plan, general design criteria, and cost estimates. The preliminary design services included preliminary design plans and supporting computations, line and grade analysis, cross sections, etc.
