WHY AM I HERE/ PURPOSE OF THIS PRESENTATION?(why do we have to listen to another boring biology talk?)RIPARIAN HABITAT Address Outstanding Questions and Concerns Regarding the Riparian Corridor • Existing Conditions • Project Impacts • Originally-Proposed Measures • Additional Enhancements • Potential Inconsistencie s (Initial Study and Guidelines )

EXISTING CONDITIONS OFF SITE RIPARIAN HABITAT
EXISTING CONDITIONS SUMMARY • On site riparian habitat —limited to “canopy” habitat • Off site riparian habitat —invasives, lack of canopy • Untreated runoff • Direct lighting • No visual/light screening • Limited wildlife access
ON SITE RIPARIAN CHARACTERIZATION
RIPARIAN IMPACTS •Sycamore removal—2,015 square feet • Removal of three non-native trees in the sub-canopy •Extension of existing parking area
ORIGINALLY- PROPOSED MEASURES (part of project design or compensation measures)•Invasive plant removal (within off site riparian habitat)-SCVWD giant reed -restricted to within property boundaries •Tree pockets (around two existing sycamores)•Curbs, Permeable Pavers and Media Filtration System (Bioretention Areas)
NEWLY-PROPOSED ENHANCEMENTS •Off site riparian plantings (up to 10,000 square feet):- Planting restricted to within property boundaries - All plant material collected wi thin watershed of Los Gatos C reek and contract-grown at local nursery (e.g. Central Coast Wilds)-Potential species incl ude arroyo willow, box elder, sycamore , native blackberry, buckeye and coast live oak -Restoration Plan to be developed in close coordin ation with SCVWD staff •Additional Permeable Pavers (6,690 square feet)-beyo nd C3 Requirement •Native tree plantings (2) within tree pockets •Exterior and landscape indirect lighting •Native vines plantings (along rear fence)
PROJECT RIPARIAN HABITAT BENEFITS SUMMARY •Stormwater pretreatment/bioretention cells/permeable pavers -reduce pollutant loading into the creek -reduce peak storm runoff •Exterior and landscape lighti ng/vine vegetation screening -reduce glare and light intr usion, human and vehicular disturbance • Removal of invasive plant species/act ive planting of native trees and shrubs -restore and enhance riparian canopy for wildlife use -provide buffer from visual and noise disturbance from development
