Title
Parkview Subdivision Stage 2 Drainage Improvements Phase I Engineering - Proposal
History
The Parkview Estates Subdivision is prone to flooding due to significant undetained runoff from unincorporated Palos Township, immediately to the east, along with the large tributary area which flows though the subdivision's online detention basin. Christopher B. Burke Engineering, LTD. of Rosemont, Illinois, (CBBEL) previously completed a high level evaluation to establish alternatives to reduce the risk of flooding. In July of 2014 the Village Board approved the project to implement Stage 1 of those improvements. Stage 1 includes the construction of additional pipes to convey undetained storm water from unincorporated Palos Township to the detention basin within the subdivision and modifications to the outlet control structure to more effectively manage the water elevation.
Stage 2 improvements include the construction of additional detention to store storm water runoff from other area tributary to Parkview Estates. The new basin is tentatively proposed to be constructed on Village property near Evergreen View Park. A conveyance pipe will be added from the Caro Vista pond to the new detention facility. The Caro Vista subdivision is also part of the original flood study. The Stage 2 improvements will also reduce the risk of flooding in that area.
To initiate the Parkview Estates Subdivision Stage 2 improvements, CBBEL has provided a proposal for phase I engineering in the amount of $67,500. The Phase I engineering will include a topographic survey, utility coordination, hydrologic and hydraulic modeling, preliminary sewer design and cost estimate. In addition, an evaluation of the Villa West pond will be conducted to determine if any operational modifications are warranted that will provide an overall benefit to the system without increasing the risk to other locations.
