Sigma helps residential and commercial development
Greenfield, Wisconsin
Greenfield Highlands is an exciting development just southwest of Milwaukee in the City of Greenfield. The development consists of single-family homes and condominiums, as well as commercial space along the retail corridor of Highway 100. A large one-acre park, playground and bike trail compliment a community-focused design. The site was historically undeveloped because of many challenges, including the presence of endangered species, need for significant topographic relief and high potential cost of infrastructure. Greenfield Highlands, LLC, along with The Sigma Group, recognized the Highlands’ tremendous potential as a mixed-use development.
Sigma’s approach was to design and implement cost-effective site improvements, while maintaining the integrity and features of natural wetlands and surrounding habitats. Sigma provided Greenfield Highlands with quality, cost-effective improvements, including the following services:
Civil / Site Engineering
Sigma served as the civil engineer for site improvements, which involved land surveying, civil engineering and construction monitoring. Project elements related to municipal infrastructure included design of a public sewer and water main extension, public roadway and intersection improvements and corrugated aluminum arch culvert with modular block headwalls.
Surveying
Sigma prepared base mapping of overall site for acquisition and assemblage of parcels and conducted property and construction staking. Prepared plat for seven single-family lots and three outlots, one being the future park land dedicated to the City for a public park with a playground.
Site Development
Sigma overcame site design challenges such as wide easements for high-tension power lines, wetlands, steep slopes and a stringent Wisconsin Department of Natural Resources regulatory process to create a low impact “smart growth,” pedestrian-friendly development. Comprehensive site development services included environmental site analysis, design of site utilities and coordination with existing utilities, stormwater containment and management, and site layout development.
Stormwater Management
Sigma led the planning and design of the development’s stormwater management and containment structures, involving six retention ponds, rain gardens and native landscaping. Sigma created infrastructure to manage the stormwater in an area-wide setting to optimize development opportunities, as well as prevent stormwater contamination.
Funding
Sigma assisted Greenfield Highlands working with the City of Greenfield to help procure an $11.5 million TIF that was necessary to assist with challenges that would have otherwise prevented site development.
