ELMHURST – Here are the top three takeaways from Monday's Public Works and Buildings Committee meeting, all revolving around flood mitigation.

1. Stormwater storage

City staff is still reviewing a Site Drainage Dissipation Data Worksheet from the Village of La Grange with the help of Christopher Burke Engineering to come up with recommendations for appropriate action and implementation for Elmhurst residential development. La Grange calculates a required dissipation storage volume based on basement depths and the surface area of permeable surfaces on each single family residential lot. Burke Engineering plans to have recommendations for stormwater storage requirements at the Jan. 27 meeting.

2. Southwest Elmhurst Wet-Weather Control Facility

Elmhurst took bids on the final three construction projects related to the Southwest Elmhurst Wet-Weather Control Facility. Archon Construction Co., Inc. of Addison was the lowest bidder to install a force main that will run from lift station to a new storage tank at $2,971,900. Maxim Construction of Volo, Ill. bid the lowest to upgrade the pump station at Saylor Avenue and Jackson Street with a $2,766,006.80 offer. The same company was the lowest bidder for the 2-million gallon prestressed concrete storage tank, which will go in at the wastewater treatment plant for $2,893,860.43. Committee members chose to compare the bids to the budgets before signing the report.

3. Rear yard drain program

The Public Works and Buildings Committee asked staff to review participants in the city's now-suspended rear yard drain cost-sharing program to see which of the three connections to the city's storm sewer – downspouts, sump pumps or rear yard drains – are most common. With recommendations from city staff, the committee plans to begin evaluating each of the three options for connections individually at the Jan. 27 meeting.
