Mountain House (near Tracy), CA
PACE was contracted by Mountain House Community Services District to create a revised Master Drainage Plan, stream restoration plan, provide storm drainage reports for community neighborhoods G and H, and to participate in the attainment of the Nationwide 27 – Stream Permit for this 4,800-acre development. Mountain House is a self-contained, 4,784-acre master planned community that, at full build-out, will be home to 43,500 residents. Incorporated into this new town is an innovative, natural approach to water resources management. PACE was the lead consultant on all of the project’s water resource issues, including development-wide stormwater management planning and creek restoration design services for Mountain House Creek, one of the development’s signature features.
PACE was responsible for a creative watershed planning program that included the Stormwater Master Plan Update for the entire development, the restoration and enhancement plan of the13,400 linear foot Mountain House Creek, and coordination with the land planner and civil engineer for a proposed residential golf course and lake system. A unique and natural-based approach to the project creek restoration and combined stormwater management program integrates the use of created wetlands and the establishment of riparian corridors for runoff water quality treatment and flood conveyance within the creek restoration program.
The stormwater management features add significant value to the overall community by including pedestrian linkage and multi-function open space areas. Additionally, the plan eliminates numerous large diameter storm drains and detention basins by routing on-site runoff through the Mountain House Creek, residential lake system and golf course. This re-routing significantly reduced capital costs for stormwater management and ensures that Mountain House Creek has year-round flows, thereby enhancing the environmental restoration and aesthetic quality of the development.
