EXHIBIT B
DIABLO VISTA PUMPING PLANT REPLACEMENT PROJECT
MITIGATION MONITORING AND REPORTING PROGRAM
Mitigation Measures
AETHESTICS/VISUAL QUALITY
Mitigation Measure AES-2: EBMUD will require the construction contractor to ensure
that the construction site is clean by storing building materials and equipment within the
proposed staging areas or in areas removed from public view where feasible, and by
promptly removing trash and construction debris that will not be reused on site.
Construction phasing will be organized to minimize equipment storage on site.
Impact being Mitigated
Impact AES-1: Project
construction could generate visual
impacts experienced in the shortterm
from nearby areas during
construction.

Mitigation Measure AES-2:
« During the detailed design phase, EBMUD will prepare a detailed Architecture
Landscape Plan for the Diablo Vista Pumping Plant Replacement Project property
consistent with the 2012 Landscape Plan. Landscape vegetation, including trees,
removed as a result of the Proposed Project will be replaced based on the Architectural
Landscape Plan that will be implemented. Drought tolerant plants and native species
identified in the Contra Costa County Fire Protection District's Suggested Fire Smart
Plant List and approved City of Lafayette Planting list will be incorporated into the
Landscape Plan as practicable.
• EBMUD will incorporate aesthetic/architectural design details for the new Diablo Vista
Pumping Plant structure, fencing, and related site improvements consistent with the
2012 Architecture Plan.
• EBMUD will require its construction contractor to provide a warranty for new
plantings for 1 year after Project completion.
• A five-year tree monitoring program will be implemented. A performance standard of
not less than 75 percent survival rate of replacement tree plantings and a requirement
that trees are evaluated as self-sustaining at the end of five years.
Impact AES-2: Project
construction could alter the site's
appearance and long-term visual
effects.

AIR QUALITY
Mitigation Measure AtR-1: The BAAQMD "Basic Construction Mitigation Measures"
will be incorporated by EBMUD into the contract specifications;
• All exposed surfaces (e.g., parking areas, staging areas, soil piles, graded areas, and
unpaved access roads) would be rocked and/or watered or soil stabilizers (nontoxic)
would be applied as necessitated by soil and air conditions.
• All land clearing, grubbing, scraping, excavation, land leveling, grading, cut and fill,
and demolition activities will be effectively controlled for fugitive dust emissions
utilizing application of water or presoaking.
• Ail haul trucks transporting soil, sand, or other loose material off-site would be covered
or require all trucks to maintain at least two feet of freeboard.
• All visible mud or dirt tracked-out onto adjacent public roads would be removed using
wet power vacuum street sweepers at least once per day. The use of dry power
sweeping is prohibited.
« All vehicle speeds on unpaved roads would be limited to 15 mph.
• Idling times would be minimized either by shutting equipment off when not in use or
reducing the maximum idling time to 5 minutes (as required by the California airborne
toxics control measure Title 13. Section 2485 of California Code of Regulations
ICCRJ).
• AH construction equipment would be maintained and properly tuned, in accordance
with manufacturer's specifications. All equipment would be checked by a certified
mechanic and determined to be running in proper condition prior to operation.
Impact AIR-1: Construction
activities would generate exhaust
emissions from vehicles/equipment
and fugitive dust particles that
could affect air quality.
