Abbott Drive Basin Retrofit

City of Elgin

OBJECTIVE

Complete a basin retrofit and stormwater quality improvements for the basin located at the end of Abbott Drive, along Tyler Creek in north-central Elgin. The project is located entirely within the floodway and floodplains of Tyler Creek.

PROJECT DESCRIPTION

This project is part of HLR’s annual detention basin design agreement with the City. The existing basin was designed to convey and improve stormwater quality from the industrial park and residential area along Abbott Drive but is not functioning as intended.

HLR designed modifications, including a two-stage detention configuration, removal of the defunct outlet structure, and enhancements to reduce peak flows, improve infiltration, and increase stormwater filtration. Additional improvements include the creation of a floodplain bench along Tyler Creek, which will enhance water quality and increase flood storage.

The project utilized an adapted XPSWMM model based on previous stormwater modeling for the Abbott Drive system. HLR developed project plans covering demolition, grading, drainage, utilities, soil erosion control, and landscaping. HLR is also assisting in contractor selection, overseeing construction, and managing permitting and environmental compliance. Additionally, HLR prepared a Green Infrastructure Grant Opportunity (GIGO) Application in 2024, with results expected in early 2025.
