BP-14. CONSTRUCTION NOISE MITIGATION MEASURES:

The project shall employ site-specific noise attenuation measures during construction to reduce the generation of construction noise and vibration.

These measures shall be included in a noise control plan that shall be submitted for review and approval by the Director of Community Development. Measures specified in the noise control plan and implemented during construction shall include, at a minimum, the following noise control strategies:
a) Equipment and trucks used for construction shall use the best available noise control techniques (e.g., improved mufflers, equipment redesign, use of intake silencers, ducts, engine enclosures, and acoustically attenuating shields or shrouds); b) Impact tools (e.g., jackhammers, pavement breakers, and rock drills) used for construction shall be hydraulically or electrically powered wherever possible to avoid noise associated with compressed air exhaust from pneumatically powered tools; and c) Stationary noise sources shall be located as far from adjacent receptors as possible, and they shall be muffled and enclosed within temporary sheds, incorporate insulation barriers, or include other measures.
d) Pile-driving is prohibited unless authorized by the Director of Community Development. If authorized, noise and vibration reducing pile-driving techniques shall be employed during construction and will be monitored to ensure no damage to nearby structures occurs (i.e., vibrations above peak particle velocity (PPVs) of 0.25 inches per second at nearby structures). These techniques shall include:
- Installing intake and exhaust mufflers on pile-driving equipment; - Vibrating piles into place when feasible, and installing shrouds around the pile-driving hammer where feasible as determined by the Director of Community Development;
- Implementing “quiet” pile-driving technology (such as pre-drilling of piles and the use of more than one pile driver to shorten the total pile driving duration), where feasible, in consideration of geotechnical and structural requirements and conditions; - Using cushion blocks to dampen impact noise, if feasible based on soil conditions as determined by the Director of Community Attachment 5

Development. Cushion blocks are blocks of material that are used with impact hammer pile drivers. They consist of blocks of material placed atop a piling during installation to minimize noise generated when driving the pile. Materials typically used for cushion blocks include wood, nylon and micarta (a composite material); and

NESTING BIRDS:

All construction and clearing activities shall be conducted outside of the avian nesting season (January 15-August 31), when feasible. If clearing and/or construction activities occur during the nesting season, preconstruction surveys for nesting raptors, special-status resident birds, and other migratory birds protected by the Migratory Bird Treaty Act shall be conducted by a qualified biologist, up to three days before initiation of construction activities, including tree removal and/or site preparation involving removal of vegetation.

The qualified biologi
st shall survey the construction zone to determine
whether the activities taking place have the potential to disturb or otherwise harm nesting birds. If an active nest is located within 100 feet (250 feet for raptors) of construction activities, the project applicant shall establish an exclusion zone (no ingress of personnel or equipment at a minimum radius of 100 feet or 250 feet, as appropriate, around the nest).

Alternative exclusion zones may be established through consultation with the CDFW and USFWS, as necessary. The City shall be notified if altered exclusion zone widths are authorized by these agencies prior to the initiation of work. The exclusion zones shall remain in force until all young have fledged.

A final report of
nesting birds, including any protection measures, shall be submitted to the Director of Community Development prior to initiation of construction activities, including tree removal and/or site preparation involving removal of vegetation. [COA] [PLANNING]

The treatment plan shall include measures to document and protect the discovered resource. Consistent with CEQA Guidelines Section 15126.4(b)(3), preservation in place will be the preferred method of mitigating impacts to the discovered resource.

Pursuant to Government Code Section 6254.10, information on the discovered resource shall be confidential. [COA] [PLANNING]

MITIGATION MEASURE

BP-17. CULTURAL RESOURCES:

In the event of the discovery of human remains during construction, there shall be no further excavation or disturbance of the site within a 50-foot radius of the remains or any nearby area reasonably suspected to overlie adjacent remains. The Santa Clara County Coroner shall be notified and shall make a determination as to whether the remains are Native American. If the Coroner determines that the remains are not subject to his authority, the Coroner shall notify the Native American Heritage Commission who shall attempt to identify descendants of the deceased Native American. If no satisfactory agreement can be reached as to the disposition of the remains pursuant to State law, then the land owner shall re-inter the human remains and items associated with Native American burials on the property in a location not subject to further subsurface disturbance.

All measures shall be printed on all construction documents, contracts, and project plans, and reviewed by the Community Development Director prior to issuance of grading and building permits.

Section 210

81.6 of the California Environmental Quality Act (CEQA) requires a Lead Agency to adopt a Mitigation Monitoring and Reporting Program
(MMRP) whenever it approves a project for which measures have been required to mitigate or avoid significant effects on the environment. The purpose of the monitoring and rep orting program is to ensure compliance with the mi ti gation meas ures during project implementation.

On July 21, 2026, the City Council certified the Environmental Impact Report (EIR) for the 800 C arlisle Way Well and Water Tank project.

The Final EIR concluded that the implementation of the project could result in significant effects on the environment and mitigation measures were identified to reduce significant impacts identified. This MMRP addresses those measures in terms of how and when they will be implemented.

Additional measures are identified to reduce construction equipment exhaust emissions. The contractor shall implement the following best management practices that are required of all projects:
• All exposed surfaces (e.g., parking areas, staging
areas, soil piles, graded areas, and unpaved access
roads) shall be watered two times per day.
• All haul trucks transporting soil, sand, or other loose material off-site shall be covered.
• All visible mud or dirt track-out onto adjacent public roads shall be removed using wet power vacuum
street sweepers at least once per day. The use of dry
power sweeping is prohibited.
