AIR QUALITY
Project will result in a
cumulatively considerable
net increase of any criteria
pollutant for which the
project region is in nonattainment under an
applicable federal or state
ambient air quality standard.
MM AIR-1: The contractor shall adhere to applicable measures contained in Table 1 of Rule 403 including, but not limited to:
• All clearing, grading, earth-moving, or excavation activities shall cease when winds exceed 25 mph per SCAQMD guidelines in order to limit fugitive dust emissions.
• The contractor shall ensure that all disturbed unpaved roads and disturbed areas within the Project are watered at least three times daily during dry weather. Watering, with complete coverage of disturbed areas, shall occur at least three times a day, preferably in the mid-morning, afternoon, and after work is done for the day. • The contractor shall ensure that traffic speeds on unpaved roads and Project site areas are limited to 15 miles per hour or less.

MM AIR-2: The following measures shall be incorporated into Project plans and specifications as implementation of SCAQMD Rule 1113:
• Only “Low-Volatile Organic Compounds” paints (no more than 50 gram/liter of VOC) consistent with SCAQMD Rule 1113 shall be used.

BIOLOGICAL RESOURCES
Interfere substantially with the
movement of any native
resident or migratory fish or
wildlife species or with
established native resident or
migratory wildlife corridors, or
impede the use of native
wildlife nursery sites?
MM BIO-1: Avian Monitoring. If construction occurs between February 1st and August 31st, a pre-construction clearance survey for nesting birds should be conducted within three (3) days of the start of any vegetation removal or ground disturbing activities to ensure that no nesting birds will be disturbed during construction. The biologist conducting the clearance survey should document a negative survey with a brief letter report indicating that no impacts to active avian nests will occur. If an active avian nest is discovered during the pre-construction clearance survey, construction activities should stay outside of a no-disturbance buffer. The size of the no-disturbance buffer will be determined by the wildlife biologist and will depend on the level of noise and/or surrounding anthropogenic disturbances, line of sight between the nest and the construction activity, type and duration of construction activity, ambient noise, species habituation, and topographical barriers. These factors will be evaluated on a case-by-case basis when developing buffer distances. Limits of construction to avoid an active nest will be established in the field with flagging, fencing, or other appropriate barriers; and construction personnel will be instructed on the sensitivity of nest areas. A biological monitor should be present to delineate the boundaries of the buffer area and to monitor the active nest to ensure that nesting behavior is not adversely affected by the construction activity. Once the young have fledged and left the nest, or the nest otherwise becomes inactive under natural conditions, construction activities within the buffer area can occur.

GEOLOGIC RESOURCES
The Project will directly or
indirectly destroy a unique
paleontological resource or
site or unique geologic
feature
MM GEO-1: Unanticipated Paleontological Resources. Any substantial excavations (i.e. over 5 feet in depth) in the proposed Project area should be monitored closely by excavation crews to identify potential fossil remains discovered while not impeding development. If fossils are found, excavation in the area will cease and a qualified paleontologist shall be retained to identify and collect the fossils. Any fossils recovered during mitigation should be deposited in an accredited and permanent scientific institution for the benefit of current and future generations.

MM HAZ-2: A hazardous spill prevention plan shall be prepared by the Contractor and submitted to the City for approval to minimize the likelihood of a spill shall be prepared prior to construction. The plan shall state the actions that would be required if a spill occurs to prevent contamination of surface waters and provide for cleanup of the spill. The plan shall follow Federal, state, and local safety guidelines and standards to avoid increased exposure to these pollutants.

MM HAZ-3: Grading and excavation at 1375 Magnolia Avenue shall follow the procedures identified in the Soil Management Plan, or most recent plan or procedures as authorized by regulatory agencies, that identifies procedures for soil management on this property. The City and the Contractor will work with the property owner to gain access to the most recent testing and other related data, as well as coordinate all excavation sites and the storage and staging of equipment, to ensure compliance with the plan and to minimize any risk of exposing any contaminated soils during Project construction.

established in thelocal general
plan or noise ordinance, or
applicable standards of other
agencies
MM NOI-1: Implement Caltrans’ Standard Specifications in Section 14-8.02, “Noise Control”. Section 14-8.02 which states: “Do not exceed 86 dBA at 50 feet from the job site activities from 9 p.m. to 6 a.m. Equip an internal combustion engine with the manufacturer-recommended muffler. Do not operate an internal combustion engine on the job site without the appropriate muffler.”
