Title
163rd Street (Saratoga Place) Storm Water Improvement - Proposal
History
The Saratoga Place Subdivision (also known as Hummingbird Hill Subdivision) (163rd Street) Storm Water Improvement Project is a continuation of the work performed as part of the Flood Risk Reduction Study completed by Christopher B. Burke Engineering, Ltd. (CBBEL). Rain events on April 17-18, 2013, solidified the need to advance this project. The collection of field survey data was completed July-August 2013. Hydrologic and hydraulic models were developed showing the existing conditions. Evaluation has identified blocked and/or poorly defined overland flow routes in the area. Recommendations were presented to staff for evaluation in August-September 2013.
The proposed improvements consist of flood-proofing residential structures, site regrading and modifications to the existing drainage system. These improvements and modifications are designed to reduce the ponding currently occurring on the property resulting in overland flow into homes. The Village will complete the installation of the proposed additional storm sewer inlet as part of Public Works’ storm water infrastructure/maintenance budget.
To facilitate the completion of flood-proofing residential structures and site regrading, the Village requested proposals from three (3) landscape companies: Carlin-Moran Landscape, Inc. of Tinley Park, IL, Mid America Landscaping of Mokena, IL, and Emerald Site Services of Frankfort, IL. Mid America Landscaping did not respond to the request to submit a proposal. Carlin-Moran Landscape submitted a proposal for $6,520, while Emerald Site Services submitted a proposal for $39,850. Staff is confident that Carlin-Moran Landscape is able and qualified to complete the work as requested. Carlin-Moran plans to reuse the existing sod and use the dirt from the swales against the building foundations. A contingency amount of $2,000 is being requested to deal with the unknown impacts during excavation of the swale.
Staff met with board members of Hummingbird Hill Townhome Association to review the proposed improvements and to discuss the intended outcomes. Staff also presented and discussed potential cost sharing options with the Hummingbird Hill Townhome Association. This discussion is ongoing.
On August 3, 2015, this item was reviewed and approved by the Public Works Committee and referred to the Board for approval.
Financial Impact
Funding to complete the work for this project is available in account #031-6007-470500.
