Algonquin Lakes

Algonquin Lakes, Algonquin, Kane & McHenry Counties, Illinois
A 309 acre mixed use residential redevelopment of a former quarry site. CGL was retained to provide preliminary and final engineering services for the development. The pre-development quarry conditions offered unique challenges in grading, earth balancing and protection of the existing groundwater lakes. The design incorporated the lakes and severely sloped areas into open space, trail systems and park land around the residential neighborhoods.

Riverwalk - Buffalo Grove, IL

Riverwalk, Buffalo Grove, Lake County, Illinois
CGL provided engineering consulting services for the two Riverwalk Office towers totaling over 500,000 SF and associated parking structures located at the NE corner of Lake-Cook Road and Milwaukee Avenue. The latest project completed was 301 Riverwalk Place, a 7-story, luxury apartment complex overlooking the Des Plaines River. In addition to site engineering, a public road extension and bike path system was required for the apartment development. A bike path extension was designed and constructed through the Des Plaines River floodplain on Lake County Forest Preserve land, connecting the Village and county path systems.

Grande Park

Grande Park, Plainfield, Illinois
A mixed use development consisting of approximately 880 acres and 2,000 dwelling units, as well as commercial sites, a school site, municipal sites, neighborhood parks, and a central park area of over 100 acres. Engineering services included coordination, design, and construction services for the sanitary and water systems, collector and arterial roadways (new extensions, as well as widening and turn lane additions to existing roads), the storm water management system, and park sites for the ultimate development, as well as the site improvements for respective neighborhoods.

Mound Road Improvements, Joliet, Illinois
Design and permitting for reconstruction of 4000 L.F. of existing Mound Road across Rock Run North Creek. Reconstruction involved widening and elevating existing road above the base flood elevation; designing a multiple box culvert system to convey flows under the road and mitigating floodplain and wetland impacts. Mitigation solution included partnering with the Will County Forest Preserve in land transfer for long term ownership of floodplain/wetland complex.

Settlers Ridge

Settlers Ridge, Sugar Grove, Illinois
Settlers Ridge is a mixed-use planned community which will ultimately encompass approximately 2,800 dwelling units on 1,320 acres. The project is being developed in phases, and incorporates a "traditional neighborhood design" approach allowing for many dwelling product types to intermingle within each subdivision unit. Conservation design criteria were integrated into the entire site planning process, resulting in open space and green belts comprising 40% of the property.

Engineering services included design and construction services for: a detailed hydrologic analysis to determine base flood elevations; an overall site inventory at environmentally sensitive areas; establishment of a master stormwater management system consisting of 9 lakes and restored wetlands promoting groundwater recharge and flow attenuation; a mile of offsite trunk sanitary sewer design; working with the Village of Sugar Grove to facilitate a major upgrade of the municipal water system to include two new wells, a treatment facility and a 1.5 million ground storage reservoir; the reconstruction of a township roadway corridor to a four lane boulevard with plans for a bridge over a railroad corridor; and onsite subdivision engineering and construction staking.

Diversion channel with check dams.

Soil Erosion and Sediment Control Services
CGL has provided Soil Erosion and Sediment Control (SESC) Services for hundreds of projects in the region. Services include plan design, assistance with Storm Water Pollution Prevention Plan (SWPPP) preparation, and permit submittal and coordination. SESC observations are provided based on NPDES requirements or at the request of the client. Observations include reports with suggestions for compliance, SWPPP updates, and coordination with the client and subcontractors. CGL has provided training to clients, as well as other groups on SESC requirements, and has worked with clients to develop their own SESC program on either a global or site specific basis.
