BACKGROUND

The proposed FY 10-11 Budget includes funds for the following neighborhood drainage projects:

Project D-09 – Brookbank Road Janet Avenue to Elm Street; Project A10 – Evans Place Janet Avenue to Elm Street; Project B10 – Richmond Avenue 67th Street North to City Limits; and Project C-10 - Western Avenue 72nd Street to Plainfield Road. Residents adjacent to these projects have requested that the City address standing water in the ditches fronting their residences. The scope of work under the proposed contract would include the removal and replacement of culverts, removal and installation of inlets as required, ditch regrading, and bank stabilization and preparation for landscape restoration. The materials and various additional contractual services required for the improvements are covered under separate agenda memos.

 

Below is a narrative of the projects:

Project D-09 – Brookbank Road from Janet Avenue to Elm Street. The existing conditions on Brookbank Road within the eastern and western right of way do not allow the conveyance of storm water from Janet Avenue to Elm Street ditches. The proposed project would include the removal and replacement of deteriorated culverts, installation of inlets as required, the enclosure of ditches as necessary, and approximately 800 lineal feet of ditch regrading.  The project goal is to allow storm water to flow at the optimal level.

 

Project A10 – Evans Place between Janet Avenue and Elm Street. The existing conditions within the eastern and western right of way do not allow the conveyance of storm water from Janet Avenue to Elm Street ditches.  The proposed project would include the removal and replacement of deteriorated culverts, removal and installation of inlets as required, the enclosure of ditches as necessary, and approximately 900 lineal feet of ditch regrading. The project goal is to allow storm water to flow from Janet Avenue to Elm Street.

 

Project B10 – Richmond Avenue from 67th Street north to City limits.  The existing conditions on Richmond Avenue within the eastern and western right of way do not allow the conveyance of storm water to the 67th Street ditch. The proposed project would include the removal and replacement of deteriorated culverts, installation of inlets as required, the enclosure of ditches as necessary, and approximately 500 lineal feet of ditch regrading.  The project goal is to allow storm water to flow at the optimal level to 67th Street.

 

Project C10 – Western Avenue from 72nd Street to Plainfield Road. The existing conditions on Western Avenue within the western and eastern right of way ditch do not allow the conveyance of storm water to flow the southern downstream limits. The proposed project would include the removal and replacement of deteriorated culverts, installation of inlets as required, the enclosure of ditches as necessary, and approximately 1,000 lineal feet of ditch regrading.  The storm water should flow within the ditch lines of Western Avenue.
