DRAFT ENVIRONMENTAL
IMPACT REPORT FOR THE CANYON HILLS PROJECT
LEAD AGENCY: CITY OF
SCH #2002091018
SITE LOCATION:
The proposed
project includes the development of 280 single-family homes, a three-acre
equestrian park and the preservation of approximately 693 acres of open
space. The proposed single-family homes
would be clustered on approximately 194 acres of the 887-acre project
site. Approximately 211 homes would be
constructed on approximately 142 acres of land on the portion of the project
site located north of Interstate 210 (“Development Area A”) and approximately
69 homes would be constructed on approximately 52 acres of land on the portion
of the project site located south of Interstate 210 (“Development Area B”). Approximately 693 acres (78 percent) of the
project site, including a large swath of land west of the proposed homes, would
be preserved as open space.
The proposed
project would also include an equestrian park on approximately three acres of
land adjacent to La Tuna Canyon Road in the southwestern portion of the project
site, which would be available for public use.
Additional open space and recreational facilities would be provided
throughout the project site. The
proposed private recreational facilities include tot lots, active play areas,
passive open space areas, a vista point with picnic area and gazebo, and a pool
with a jacuzzi, restroom building and barbeque area.
