Westpark is a 1,500 acre master planned community located in the City of Roseville and is part of the approved West Roseville Specific Plan. Westpark is home to 4,585 households. The property was acquired in 1989 as raw, treeless, unentitled land and required a full complement of local entitlements including a General Plan Amendment, a Specific Plan, EIR, Development Agreement and annexation. Federal and State permitting was also required including issuance of a 404 permit from the US Army Corps of Engineers, a Biological Opinion from the US Fish and Wildlife Service, Water Quality Certification and Streambed Alteration Agreement from the State of California. The entitlement effort included extensive public outreach and community involvement resulting in broad support during the public hearing process and City of Roseville approval in 2004. The project was challenged in four separate ostensible environmental law suits and two initiatives. Westpark was able to resolve all of the lawsuits without ever going to court and was further able to successfully challenge both initiatives. After overcoming all of these challenges and following approval of a broad spectrum of entitlements and development agreements, Westpark sold the master planned community to a consortium of builders that included Pulte Homes, Centex Homes and Lennar Homes. The sale was the largest land development sale in the Greater Sacramento region.

These builders began construction in 2005 and then stopped in 2008 with the collapse of the real estate market. Westpark then purchased Phases 3 and 4 back from the builders at the end of 2009.
