The improvements start at the east curb return of the intersection of US 64 (Memorial Drive) and E. 151st Street and continued east for 5/8 of a mile.  The basic scope was to widen the arterial to 4 lanes and improve frequently flooded drainage along the project corridor.

The project scope involves the following major design tasks:
  • Street roadway surface widening and profile elevations
  • Major stormwater analysis and design
  • Stormwater pollution prevention plan
  • Utility relocations
  • Waterline improvements
  • Sanitary sewer relocations
  • Construction sequence
  • Traffic control signalization, striping and signage
  • Coordination with commercial site improvements
  • Right of way plan, negotiation and restoration
The proposed curb and gutter with enclosed drainage system involved relocation of existing utilities and traffic signals.  This widening project has three different typical sections.  Section one has a 10 inch PCC pavement with integral curbs over an eight (8) inch aggregate with sidewalk at both sides.  The second section was a ten (10) asphalt concrete pavement with 2'-2" combined curb and gutter over eight (8) inches of ODOT Type A aggregate base and no sidewalk typical section.  The third section is equivalent to the first section without sidewalks.  The width of the pavement varies from section to section from 36 feet wide with paved shoulders to 48 feet curb ad gutter section with concrete sidewalks on the west side to 62 feet wide with 2 feet paved shoulders at the east end of the project.  All driveways are being reconstructed and handicap access ramps designed to comply with ADA requirements are included where sidewalks are included.  The roadway widening included pay item quantities, plan and profile sheets, typical sections, striping plans, construction sequence plans details, plan sheets, cross sections, and utility coordination.

Stormwater improvements included drainage area map, stormwater plan and profiles, inlet and pipe analysis and design.  A hydrology and hydraulics (H&H) analysis was done to size all pipes, inlets, and reinforced concrete boxes for the 100-yr storm event.  The design included the combination of pipes, area inlets, and open drainage controlled stormwater access, gutters and street inlets.  986 feet of RCP pipe was used along the project corridor with sizes ranging from 15 inches to 48 inches with 10 manholes.  638 feet of reinforced concrete box was designed and used along the project to provide both capacity and hydraulic grade requirements.  The RCB ranged from an 8'X5' connecting the proposed drainage to the existing followed by a section of 7'X5' RCB, a 6'X5' RCB to a 20 ft of DLB 10'X3' cast in place section to a 6'X5' area and street inlets were designed throughout the project as deemed necessary from the H&H analysis.

The project also included utility relocation.  Waterline relocation included 2,400 feet of PVC pipes ranging from 12 inch PVC to 4" PVC pipe with ductile iron fittings.  A section of the existing sanitary sewer was relocated outside the proposed pavement to facilitate maintenance.  Approximately 476 feet of 8 inch ductile iron pipe was designed and two new sanitary sewer manholes were installed.

The traffic signalization plan included the installation of 480 feet of 3 inch conduit, proposed pull boxes, and existing traffic signal relocation and new signal poles.  New pavement markings and traffic control plans were designed to meed current MUTCD stripping and signalization standards.

The total engineers' construction cost for this project is approximately, $5.0 million dollars.
