2001 Environmental Review of City Activities

New Search

Executive Summary The basic purpose of the Environmental Review was to provide an initial screening of City activities to determine whether they have the potential to affect the natural environment. The assessment is intended to provide initial focus as to the steps the City should take to identify and manage activities that may effect the overall environment, habitat, and ESA-listed species. No individual activity has been examined in detail. Therefore, this assessment should not be solely relied upon for conclusions or decisions regarding impacts of City activities on the environment, and should not be used to determine the potential for "take" as defined under the ESA. Eleven interview sessions with 90 City staff persons. were conducted to define and describe City activities. As a result of these sessions and analysis of materials received from the. sessions, the Environmental Review identified and assessed: • 180 specific City activities in 24 process or function categories that potentially affects the natural environment • 18 types of potential effects on the natural environment • 10 types of "delivered" habitat effects City activities with the highest-rated potential to negatively affect the overall natural environment include: • Stormwater outfalls discharge • Use of fleet vehicles • Wastewater treatment and effluent discharge • Road construction City activities with highest potential to positively affect the overall natural environment include: • Integrated Pest Management program • Amazon Creek stream and bank improvement project • Delta Ponds wetlands restoration project • Lower Amazon wetlands restoration project The activities with highest potential to negatively affect ESA-listed Chinook salmon include: • Stormwater outfalls discharge • Use of fleet vehicles • Wastewater treatment and effluent discharge • Road construction • Vehicle parking areas operation and maintenance • Mowing of banks for open channel and ditch maintenance • Fire fighting (industrial /commercial /multi-family units) • Tree and brush removal to maintain flow in channels • Extreme wet weather overflow events 1 PRELIMINARY REVIEW DRAFT (1/23/2001).
