Project Description

Mountain Park

Located near the 241 Tollway and Gypsum Canyon Wash, the proposed project will include development of up to 2,500 residential units in a gated community, an elementary school, neighborhood parks, community park and natural open space dedications on approximately 3,200 acres of land. The project includes a new SR-241 freeway interchange at Weir Canyon Road; a freeway bridge overcrossing along SR-241; SR-91 and Gypsum Canyon Road freeway interchange upgrades; three water reservoirs; on-road (Class 11) public bikeway through the community; regional riding and hiking trails with connections to the Santa Ana River Trail and Coal-Gypsum Canyon trail; a trail staging area with grade separated riding and linking trail undercrossings at two street crossing locations; a regional drainage culvert to collect and convey runoff from project development areas; and upland watershed natural areas to the Santa Ana River.

The plan’s focus is creation of environmentally compatible neighborhoods that address the watershed’s requirements to sustain healthy natural creeks and drainages while allowing for water quality treatment of the project’s runoff. During the EIR stage, Fuscoe performed environmental studies to create watershed design features that protect the Santa Ana River’s endangered species, such as the Santa Ana Sucker Fish. Innovative designs for preserving and stabilizing water courses and hydromodification impacts while enabling residential and infrastructure uses were tested as well as “bio-reactive” water treatment staging to ensure direct discharge to the Santa Ana River meets regulatory expectations.
