Project Overview

Bleck Engineering has been involved with the Northwestern Lake Forest Hospital Grayslake Campus from the initial 136,000 square foot Outpatient and Acute Care Center built in 2004, to its Free Standing Emergency Center in 2009, Ambulatory and Surgery Treatment Center, and Cancer Care Center completed in 2011, and site access improvements to Illinois Route 120 in 2015. The campus was designed utilizing best management practices in conservation and sustainable design. Recent additions to the Hospital are LEED Silver Certified.

One of the main features of Northwestern Grayslake Hospital is the native landscape. The campus was designed utilizing best management practices in conservation and sustainable design for the treatment of water quality and reduction in runoff quantity. Bleck Engineering designed a series of measures to reduce stormwater volumes and associated pollutant loads (nitrogen, phosphorus, sediment, road salt, etc.) through an innovative stormwater management concept. This was the one of the first major installation of the Stormwater Treatment Train in Lake County.  The system is composed of open swales with deep rooted native vegetation for stormwater conveyance, upland prairie bio‐filtration, preservation of wetlands, settling basins and open water detention ponds. Working in combination, these methods increase opportunities for pollutant removal through biological and mechanical means, while significantly reducing the rate and volume of stormwater runoff.
