Environmental Planning Activities

Environmental Compliance Program

TCA’s 2,200 acres of open space

Provides habitat for multiple species, including those considered threatened and endangered or limited local populations (e.g., coastal California gnatcatcher, brodiaea, coastal cactus wren, mountain lion., etc.)

5

Transfer of TCA’s Mitigation Lands

Long term goal is to transfer these lands to other management entities

– For example in 2010, Siphon Reservoir (214 acres) was transferred to IRWD

– Remaining steps, include identifying parties acceptable to USFWS and CDFW for long term ownership and possible funding

Type Chain link V-Mesh Galvanized:

Difficult to climb

Low maintenance

80-99% Efficacy

30-40 years longevity

Integrate escape routes (jump

out ramps).

Height 8-12’ Cougars are excellent climbers,

as well as superb jumpers. They

can jump up to 20’ from a near

standstill.

Deer are agile and can jump

over a 6-ft fence with ease.

Bottom Buried Strongly recommended in areas

with wildlife capable of digging

under the fence (e.g. coyotes)

to create crawl holes.

Top Outrigger To prevent animals from

climbing over.

Location Closer to

the

roadway

~670 acres of additional

habitat would be available for

wildlife use.
