I ITEM ExPLANATIoN: The Cannon Road Reach 1 project is required to bridge wetland and rip
where it crosses Macario Canyon. The approved project contains a 450 foot :
bridge estimated to cost $3.5 million. This bridge does not span the enti
area. Construction of bridge abutments will involve filling over 0.8 acres
scrub and 0.1 acre of marsh directly beneath the bridge.
The California Coastal Commission has required a 3:l replacement miti

The mitigation plan requires that 4.8 acres of wetlands area be restored c
Plans are currently being developed to landscape 0.9 acres under the bridge

accomplished in close proximity to the bridge. This option would mink impacts at a cost of $1.5 to $2.0 million.
This option was rejected under environmental review as too costly. These 1

development.
Alternative 5 - would acquire additional mitigation lands outside of Mac:
This approach was rejected as unacceptable to resource agencies.

MAW0 PARK MASTER PLAN
In reviewing the issues involved with mitigation within Macario Park, it has
increasingly apparent that the current concept plan will likely involve su
relocation of sensitive riparian habitat, which could involve up to 24
mitigation. Mitigation levels of this magnitude could not be developed w
park.
It may be extremely difficult to obtain permits from resource agencies to ac,
development of the canyon floor into active recreational facilities. These di
will likely increase with time as urbanization of the upstream water shed :
irrigation flows which will nourish additional riparian and wetland habitat.
In order to further assess viability of the proposed park concept plan and
maximum flexibility, it would be advisable to further pursue environmental
of the current concept plan at an early date.
RECOMMENDATION
It is recommended that the Council approve the Alternative 3 mitigation
presentation to the permit agencies and budget appropriate funds for envirc
studies of the Macario Park concept Plan.
FISCAL IMPACT:
Initial park planning and supplemental environmental studies will be buc
$200,000 from the Public Facilities Fee (PFF) Fund.
