e) Have soils incapable of adequately supporting the use of septic tanks or alternative wastewater disposal systems where sewers are not available for the disposal of wastewater? No Impact. The City does not use any septic tanks, and there would be no impact from septic tanks or alternative wastewater disposal systems with implementation of the Proposed Project. No new or substantially greater impacts would occur. No changes or new information would require preparation of a subsequent EIR. f) Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature? Less Than Significant Impacts/No Changes or New Information Requiring Preparation of an EIR.
As with any development under the General Plan, any future development for the Proposed Project would be required to investigate potential paleontological resources for that specific project site, consistent with Mitigation Measure 3-3. Implementation of Mitigation Measure 3-3 would ensure that impacts related to paleontological resources are less than significant. No changes or new information would require the preparation of a subsequent EIR.
5.7.3 Adopted Mitigation Measures Applicable to the Proposed Project The Proposed Project would incorporate Mitigation Measure 3-3 related to paleontological resources, which is included in Section 5.5, Cultural Resources.
5.8 GREENHOUSE GAS EMISSIONS
5.8.1 Summary of Impacts Identified in the Certified EIR The Certified EIR found that the Approved Project would not experience an increase in GHG emissions at project buildout, and even with additional growth the impact would be less than significant.
The Certified EIR found that the Approved Project’s impact from GHG emissions would be significant in the absence of federal, state, and local plans to achieve long-term GHG reduction targets for the State. The Certified EIR identifies mitigation measures to address the Approved Project’s impact on GHG emissions and conflicting with applicable policies. With the implementation of the mitigation measures, the impact to conflicting with applicable plan, policy, or regulations would remain significant and unavoidable.

5. Environmental Analysis
4-1 The City of Los Alamitos shall include the following actions in the City’s Implementation Plan to ensure that the City continues on a trajectory that aligns with the long-term state GHG reduction goals of Executive Order S-03-05.
Work with local and regional agencies to install appropriate recharging stations to support the use of electric vehicles. Work with developers to install recharging stations at appropriate activity and employment centers to support electric vehicle use. Conduct energy audits on all City facilities and incorporate cost-effective measures to increase energy efficiency.
Public education on energy conservation. Coordinate with local utilities to provide energy conservation information to the public.
Promote energy-efficient design features such as appropriate site orientation, renewable energy systems, use of lighter color roofing and building materials, and passive ventilation and cooling techniques.
Seek grants and other outside funding for energy efficiency improvements to public or private facilities and structures.
Work with the Los Alamitos Unified School District, the City of Seal Beach, and Rossmoor to obtain grant funding, conduct planning, and construct new and improved existing bicycle and pedestrian facilities to provide safe routes to schools. Remove barriers that discourage active pedestrian and bicycle routes. Expand facilities and amenities that encourage active routes, such as increasing the number of Class II bike lanes along potential school routes, particularly those that parallel Los Alamitos Boulevard and Katella Avenue.
Create and implement a pedestrian and bicycle master plan to identify improvements, timing, and funding mechanisms.
Identify funding and design options for bicycle and pedestrian signage along bicycle routes, in the downtown, and at key trailheads or connection points, with an emphasis on connections to schools and the downtown. Bicycle signage should be consistent with signs of neighboring jurisdictions, yet distinct for Los Alamitos. Coordinate with neighboring jurisdictions on improving connections to existing and planning future bicycle and pedestrian trails.
Work with OCTA and local businesses to enhance bus stops in Los Alamitos and Rossmoor.

Coordinate with OCTA on its Long Range Transportation Plan to design bus rapid transit service and stop locations along Katella Avenue.
Explore the use of parking meters along public streets and on City-owned lots, especially in the downtown.
Identify opportunities for bicycle parking in the downtown, including the conversion of single parallel parking spaces along smaller side streets into on-street or curb-adjacent bicycle parking. Bike racks should serve as functional public art and can reflect the types of businesses or uses.
5.9 HAZARDS AND HAZARDOUS MATERIALS
5.9.1 Summary of Impacts Identified in the Certified EIR The Certified EIR determined that buildout associated with the General Plan Update (the Approved Project) would involve the transport, use, and/or disposal of hazardous materials. Additionally, the increase in the number of residences and businesses would increase the number of hazardous materials in the city. The Certified EIR determined that the demolition of buildings within the Project Site could release asbestos materials and lead-based paint. However, existing regulations with respect to hazardous material transportation, management, and disposal would minimize the potential impact from hazardous materials.
The Certified EIR determined that the Approved Project has numerous hazardous sites undergoing investigation and remediation within and adjacent to the city. However, the hazardous sites are subject to stringent laws and regulations, and compliance would result in a less than significant impact.
The Certified EIR determined that the Project Site is not within a two-mile radius of a public airport, and no private airstrips are in the vicinity of the Project Site. The JFTB owns two private runways and associated taxiways, hangars, and clear zones. A Clear Zone is designated surrounding each end of the pair of runways.
But the Certified EIR determined that the Clear Zones are limited to within the Los Alamitos JFTB boundaries.
The Approved Project does not include any changes within the base and did not have any airport land use plans within the city, and no impact occurred.
The Certified EIR for the Approved Project determined that the Approved Project would not result in substantial changes to circulation patterns and emergency access routes, and therefore the impact was less than significant.
The Certified EIR for the Approved Project determined that the Project Site is in an urbanized area and would not be subject to wildland fires. Therefore, there was no impact to risks involving wildland fires.

Less Than Significant Impact/No Changes or New Information Requiring Preparation of an EIR.
Consistent with the Proposed Project, future residential land uses would use and store hazardous materials typical of residential uses, such as cleaners, pesticides, batteries, paints, oils, and other household items. The Proposed Project would not introduce more residences than what is allowed under the Approved Project and would therefore lead to a similar amount of hazardous materials on the Project Site. As with the Approved Project, the Proposed Project would follow existing regulations for the proper handling, transport, use, storage,

and disposal of hazardous materials. No new or substantially greater impacts would occur. No changes or new information would require preparation of a subsequent EIR. b) Create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment? Less Than Significant Impact/No Changes or New Information Requiring Preparation of an EIR.
The Certified EIR determined that the demolition of existing structures on site could result in the accidental release of asbestos-containing materials and lead-based paint, but all development would be required to comply with California Health and Safety Codes, OSHA, and SCAQMD Rule 1403, which results in a less than significant impact. As with the Approved Project, development under the Proposed Project may require removal of lead-based paint and asbestos-containing material. As with the Approved Project, this would be project specific, and all future projects would be required to comply with regulations for the proper removal, handling, and disposal of lead-based paint and asbestos-containing material. No new or substantially greater impacts would occur. No changes or new information would require preparation of a subsequent EIR. c) Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school? Less Than Significant Impact/No Changes or New Information Requiring Preparation of an EIR.
There are 10 public schools, an adult school, and numerous private schools in Los Alamitos. The Certified EIR determined that the Approved Project may involve development of land uses that involve the use of hazardous materials or generate hazardous emissions within one-quarter mile of a school. This would be project specific, and as determined by the Approved Project, all future projects would be required to comply with applicable policies and regulations such as state regulations, provisions of the Los Alamitos Municipal Code, and policies in the General Plan Update, which would result in a less than significant impact. The Proposed Project does not have any schools within the Project Site, and Oaks Middle School is located 0.2 mile west of the west boundary (LAUSD 2021). The Proposed Project would not increase the maximum number of residences within the Project Site compared to the Approved Project. The use of hazardous materials during construction and operation follows existing regulations for the proper handling, use, storage, and disposal of such materials. No new or substantially greater impacts would occur. No changes or new information would require preparation of a subsequent EIR.
d) Be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code § 65962.5 and, as a result, would it create a significant hazard to the public or the environment?
Less Than Significant Impact/No Changes or New Information Requiring Preparation of an EIR.
The Certified EIR identified numerous hazardous material sites within the city. There are four Leaking Underground Storage Tank (LUST) cleanup sites within the Project Site, but they are Completed–Case Closed (SWRCB 2021). There were no other hazardous material sites located on hazardous material databases (DTSC 2021; USEPA 2021a; USEPA 2021b; CalRecycle 2021b). However, the hazardous sites are subject to compliance with stringent laws and regulations, and future potential developments would be required to address the potential impact. The Proposed Project would not increase the number of residences within the Project

5. Environmental Analysis
Site compared to the Approved Project, and impacts would be similar as the Approved Project. No new or substantially greater impacts would occur. No changes or new information would require preparation of a subsequent EIR.
e) For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard or excessive noise for people residing or working in the project area? No Impact. As concluded in the Certified EIR for the Approved Project, there are no public airports located within 2 miles of the City and the Project Site is not located within an airport land use plan. The Los Alamitos JFTB encompasses nearly the entire southern half of the city. The JFTB owns two private runways and associated taxiways, hangars, and clear zones. A Clear Zone is designated surrounding each end of the pair of runways. But the Certified EIR determined that the Clear Zones are limited to within the Los Alamitos JFTB boundaries, and the Proposed Project does not include any changes within the base. As with the Approved Project, implementation of the Proposed Project would not conflict with an airport land use plan. No new or substantially greater impacts would occur. No changes or new information would require preparation of a subsequent EIR.
f) Impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan?
Less Than Significant Impact/No Changes or New Information Requiring Preparation of an EIR.
The Certified EIR for the Approved Project concluded there would be alteration, intensification, and redistribution of land uses in the city, but these would not result in substantial changes to circulations patterns and emergency access routes. The Proposed Project would not increase the maximum number of residences within the Project Site compared to the Approved Project, and impacts would be similar to the Approved Project. As with the Approved Project, implementation of the Proposed Project would not substantially change circulation patterns and emergency access routes. Any future development as a result of the Proposed Project would be reviewed and approved by the City and Fire Department prior to approval and/or construction, which would ensure adequate emergency access to development sites and emergency access on public rights-of-way. No new or substantially greater impacts would occur. No changes or new information would require preparation of a subsequent EIR.
g) Expose people or structures, either directly or indirectly, to a significant risk of loss, injury or death involving wildland fires?
No Impact. As determined in the Certified EIR, the city is not proximate to wildland area and is designated as a moderate fire threat; there would be no impact. As with the Approved Project, implementation of the Proposed Project would not be proximate to wildland areas and therefore would not expose people or structures to wildland fire risks. No new or substantially greater impacts would occur. No changes or new information would require preparation of a subsequent EIR.
5.9.3 Adopted Mitigation Measures Applicable to the Proposed Project No mitigation measures related to hazards and hazardous materials were identified in the Certified EIR.

5.10 HYDROLOGY AND WATER QUALITY
5.10.1 Summary of Impacts Identified in the Certified EIR The Certified EIR found that construction and operation of planned development per the Approved Project has the potential to discharge sediment and pollutants to storm drains and receiving waters. However, by complying with federal and local regulations, development in accordance with the Approved Project would result in a less than significant impact on the City’s water quality standards and waste discharge requirements.
The Certified EIR found that the development in accordance with the Approved Project would increase demand for water. However, the increased water demand would be reflected in the Municipal Water District of Orange County’s yearly basin evaluations and would not lead to an exceedance in groundwater pumping. Thus, impacts to groundwater supply and recharge would be adequately addressed by Section 16.08.060 of the Los Alamitos Municipal Code and CEQA guidelines, and impacts were less than significant. Similarly, the Approved Project would not substantially degrade water quality and impacts were less than significant. Projects that resulted in 5,000 square feet or more of impervious surfaces were required to submit a priority project–specific water quality management plan (WQMP) to the City for approval prior to the City issuing any building or grading permits; the project-specific WQMP was required to include appropriate best management practices (BMPs).
The Certified EIR found that the stormwater drainage around the city and its sphere of influence (SOI) could change due to site-specific grading and construction of impervious surfaces. However, given that soil erosion is not an issue based on the City’s topography and the NPDES requirements for construction permitting and operation, impacts on existing drainage patterns and potential soil erosion were less than significant. Similarly, impacts on existing drainage patterns and potential flooding were less than significant.
The Certified EIR found that the Approved Project would not create or contribute runoff water that would exceed the capacity of existing or planned stormwater drainage systems. Projects that result in 5,000 square feet or more of impervious surfaces were required to submit a priority project–specific WQMP to the City for approval prior to the City issuing any building or grading permits; the project-specific WQMP is required to include appropriate BMPs. Impacts were less than significant.
The Certified EIR found that the Approved Project would not place housing within a 100-year flood hazard area and would result in a less than significant impact. Furthermore, the Certified EIR found that the area around the Carbon Creek Channel and San Gabriel River are designated for open space, and the Approved Project would not place structures within the hazard area that would impede or redirect flood flows. These hazard areas would remain in existing conditions, and impacts were less than significant. Similarly, impacts from inundation by seiche, tsunami, or mudflow were less than significant.
The Certified EIR found that potential damage to the city and the SOI from a failure of the Prado Dam was not an issue due to dam upgrades and that dam failure was considered unlikely. Therefore, impacts were less than significant given the time it would take for the flood waters to reach the city. Furthermore, the City addresses flood risks in the Los Alamitos Emergency Operations Plan, and a California Office of Emergency

CITY OF LOS ALAMITOS
5. Environmental Analysis
Services (Cal OES) office in Los Alamitos provides local-level Cal OES information and resources in all phases of emergency management. Thus, impacts from potential dam failure would be less than significant.

a) Violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or groundwater quality?
Less Than Significant Impact/No Changes or New Information Requiring Preparation of an EIR.
The Certified EIR found that construction and operation of planned development per the Approved Project had the potential to discharge sediment and pollutants to storm drains and receiving waters. Such development would be required to prepare a SWPPP, WQMP, and NPDES permit. Any future development associated within the Proposed Project would also comply with the SWPPP, WQMP, and NPDES permit for the Approved Project. The Proposed Project would not increase development floor area nor impervious surfaces. No new or substantially greater impacts would occur. No changes or new information would require preparation of a subsequent EIR.
b) Substantially decrease groundwater supplies or interfere substantially with groundwater recharge such that the project may impede sustainable groundwater management of the basin? Less Than Significant Impact/No Changes or New Information Requiring Preparation of an EIR.
The Certified EIR found that the Approved Project would not substantially decrease groundwater supplies or interfere substantially with groundwater recharge. As with the Approved Project, any future development as a result of the Proposed Project would be subject to all development requirements, such as setbacks and landscaping. The Proposed Project would not expand the building footprint or increase impervious surfaces.
Implementation of the Proposed Project would not decrease groundwater supplies or interfere with groundwater recharge. No new or substantially greater impacts would occur. No changes or new information would require preparation of a subsequent EIR.
c) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river or through the addition of impervious surfaces, in a manner which would: (i) result in a substantial erosion or siltation on- or off-site; (ii) substantially increase the rate or amount of surface runoff in a manner which would result in flooding on- or offsite; (iii) create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff; or (iv) impede or redirect flood flows?
Less Than Significant Impact/No Changes or New Information Requiring Preparation of an EIR.
The Proposed Project would not develop new floor area nor increase impervious surfaces. The Proposed Project amends the Land Use Element to allow density within the Project Site to increase from 30 units per acre to 60 units per acre with a development cap of 588 dwelling units, which would keep the Proposed Project within the envelop of the Approved Project. As such implementation of the Proposed Project would not generate more development and would not alter existing drainage pattern of the site nor the project area beyond what is allowed under the Approved Project. The Proposed Project would not alter the course of a stream or river. No new or substantially greater impacts would occur. No changes or new information would require preparation of a subsequent EIR.

d) In flood hazard, tsunami, or seiche zones, risk release of pollutants due to project inundation? Less Than Significant Impact/No Changes or New Information Requiring Preparation of an EIR.
The Certified EIR determined that the Approved Project is not near any large bodies of water that could generate tsunamis or seiches. Although there are no large water tanks in the area that could impact the Project Site, there are dams in the region that could create flooding impacts. The Certified EIR found that potential damage to the city and the SOI from a failure of the Prado Dam was not an issue due to dam upgrades and that dam failure was considered unlikely. Therefore, impacts were less than significant given the time it would take for the flood waters to reach the city. Furthermore, the City addressed flood risks in the Los Alamitos Emergency Operations Plan, and a Cal OES office in Los Alamitos provides local level Cal OES information and resources in all phases of emergency management.
The Proposed Project would amend the General Plan Land Use Element to allow density within the Project Site to increase from 30 units per acre to 60 units per acre. The Proposed Project would remain capped at 588 units and would not increase the number of dwelling units on the Project Site compared to the Approved Project. Therefore, the Proposed Project would result in a less than significant impact to flood hazard and inundation. The Proposed Project would comply with the SWPPP, WQMP, and NPDES permit. No new or substantially greater impacts would occur. No changes or new information would require preparation of a subsequent EIR.
e) Conflict with or obstruct implementation of a water quality control plan or sustainable groundwater management plan?
Less Than Significant Impact/No Changes or New Information Requiring Preparation of an EIR.
The Proposed Project would not construct more dwelling units and new floor area nor increase impervious surfaces beyond what is allowed under the Approved Project. Construction and operation of the Proposed Project would comply with the SWPPP, WQMP, and NPDES permit. Therefore, the Proposed Project would not conflict with or obstruct the implementation of a water quality control plan and would not impact groundwater. No new or substantially greater impacts would occur. No changes or new information would require preparation of a subsequent EIR.
5.10.3 Adopted Mitigation Measures Applicable to the Proposed Project No mitigation measures related to hydrology and water quality were identified in the Certified EIR.
5.11 LAND USE AND PLANNING
5.11.1 Summary of Impacts Identified in the Certified EIR The Certified EIR determined that the Approved Project was consistent with applicable land use plan, policy, and regulations including SCAG RTP/SCS, State Planning Law and California Complete Streets Act, and Airport Environs Land Use Plan.

a) Physically divide an established community?
No Impact. The Approved Project involved alteration, intensification, and redistribution of land uses in the city, and the changes were largely limited to already-urban uses. The Proposed Project would allow for increased residential density within the Project Site and would not include roadway closures, which could physically divide an established community. As with the Approved Project, the Proposed Project would not result in impacts relating to division of an established community. No new or substantially greater impacts would occur. No changes or new information would require preparation of a subsequent EIR. b) Cause a significant environmental impact due to a conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect? No Impact. As determined in the Certified EIR, the Approved Project was consistent with applicable land use plan, policies, and regulations. The Proposed Project amends the General Plan Land Use Element to allow density within the Project Site to increase from 30 units per acre to 60 units per acre. The Proposed Project would be capped at 588 units and would therefore not develop units beyond what is allowed as part of the Approved Project. As with the Approved Project, implementation of the Proposed Project would not cause a significant environmental impact due to conflict with any land use plan, policy, or regulation.

No Impact. The Project Site is within an urbanized area that is largely developed with commercial, retail, and office uses. No mineral extraction activities exist on the Project Site. The Proposed Project amends the General Plan Land Use Element to allow density within the Project Site to increase from 30 units per acre to 60 units per acre. The Proposed Project would be capped at 588 units and would therefore not develop more units than are allowed under the Approved Project. Therefore, the Proposed Project would not result in any new impacts to mineral resources. No new or substantially greater impacts would occur. No changes or new information would require preparation of a subsequent EIR.

b) Result in the loss of availability of a locally important mineral resource recovery site delineated on a local general plan, specific plan or other land use plan? No Impact. The Project Site is within an urbanized area that is largely developed with commercial, retail, and office uses. No mineral extraction activities exist on the Project Site. The Certified EIR for the Approved Project determined that there are no locally important mineral recovery sites in the city. The Proposed Project is in the city and would not result in more development than is allowed under the Approved Project. Therefore, the Proposed Project would not result in any new impacts to mineral resources. No new or substantially greater impacts would occur. No changes or new information would require preparation of a subsequent EIR.
5.12.3 Adopted Mitigation Measures Applicable to the Proposed Project No mitigation measures related to mineral resources were identified in the Certified EIR.
5.13 NOISE
5.13.1 Summary of Impacts Identified in the Certified EIR The Certified EIR determined that the Approved Project would not result in a substantial long-term increase in ambient noise levels generated by vehicle traffic. The Certified EIR found that buildout of the Approved Project would result in noise level increases up to 1.1 decibels (dB) from existing conditions. These incremental increases would be below the level that is considered barely perceptible and would be below the thresholds.
Therefore, traffic-related noise impacts to off-site uses from implementation of the Approved Project were less than significant.
The Certified EIR determined that the Approved Project would not expose sensitive receptors to elevated noise levels from traffic and stationary noise. Although noise-sensitive land uses would be exposed to transportation noise sources, including vehicular traffic and aircraft overflights, Public Facilities and Safety Element Policies
4.1 to 4.6 would reduce noise impacts to sensitive uses from transportation and stationary noise sources by requiring an assessment to analyze potential noise impacts and the implementation of mitigation measures to meet applicable standards. With the noise standards in the Los Alamitos Municipal Code and implementation of the General Plan Public Facilities and Safety Element policies related to noise, impacts from transportation and stationary noise sources were less than significant.
The Certified EIR determined that the Approved Project could create a substantial short-term increase in groundborne vibration. The Certified EIR identified Mitigation Measure 7-1 to reduce vibration impacts associated with construction of projects to the extent feasible. However, because of distance and other site conditions that may render its implementation infeasible or ineffective for future projects, Mitigation Measure 7-1 would not guarantee that vibration impacts of construction would be reduced to less than significant levels.
Consequently, impacts were significant and unavoidable.
The Certified EIR determined that the Approved Project could create a substantial short-term increase in noise levels in the vicinity of noise-sensitive land uses. The Certified EIR found that construction activities would result in temporary noise increases in the vicinity of sensitive land uses. The Certified EIR identified Mitigation

Measure 7-2 to reduce noise impacts associated with construction activities to the extent feasible. However, because of distance, source to receiver geometry, and other site conditions that could render its implementation infeasible or ineffective for future projects, Mitigation Measure 7-2 did not guarantee that construction noise impacts would be reduced to less than significant levels. Consequently, impacts were significant and unavoidable.
The Certified EIR determined that the Approved Project would not result in increased noise exposure from operation of the Los Alamitos JFTB. The Certified EIR found that operations at the Los Alamitos JFTB would continue to contribute to the ambient noise environment due to major sources of noise such as vehicular traffic on city roadways, major events at the base, and aircraft operations. Events such as major military training exercises, which occur once a month, would result in an increase in vehicular activity due to military truck conveys accessing the base. However, these events would continue to be sporadic, causing noise increases due to truck passbys that occur for short periods of time. Moreover, the Approved Project would not modify the land use plan for the areas in the vicinity of the base south of Katella Avenue and east of Los Alamitos Boulevard. For these reasons, noise impacts would be less than significant.
The Certified EIR for the Approved Project determined that the closest public airports to Los Alamitos are the Long Beach Airport, approximately three miles west of the city, and the Fullerton Municipal Airport, approximately six miles northeast of the city. However, the airport land use plans for these airports do not extend into the city or its SOI. There were no public or public use airports in Los Alamitos, and no impact would occur from airport facilities.

The Proposed Project would not result in a substantial increase in construction noise since the Proposed Project would involve the same Project Site and the same types of construction equipment and construction techniques as the Approved Project. Consistent with the analysis of the Approved Project, the Proposed Project would result in potentially significant construction noise impacts unless mitigated through Certified EIR Mitigation Measure 7-2. The Proposed Project would not create a new significant impact or a substantial increase in the severity of previously identified effects that would require the preparation of a subsequent EIR.
The Proposed Project amends the General Plan Land Use Element to allow density within the Project Site to increase from 30 units per acre to 60 units per acre. Since the Proposed Project would be capped at 588 units, the operation of the Proposed Project would result in less than significant impact and would not create a new significant impact or a substantial increase in the severity of previously identified effects that would require the preparation of a subsequent EIR.
b) Generation of excessive groundborne vibration or groundborne noise levels? Less Than Significant Impact/No Changes or New Information Requiring Preparation of an EIR.
The Certified EIR determined that the Approved Project could result in development that creates elevated levels of groundborne vibration and groundborne noise during construction activities. The Proposed Project amends the General Plan Land Use Element to allow density within the Project Site to increase from 30 units per acre to 60 units per acre. Any future construction resulting from the Proposed Project would be similar to that of the Approved Project and within the same Project Site. In addition, vibration impacts are highly localized, so any future construction under the Proposed Project would not result in greater vibration impacts compared to the Approved Project. Consistent with the analysis of the Approved Project, the Proposed Project would result in potentially significant construction vibration impacts unless mitigated through Certified EIR

Mitigation Measure 7-1. The Proposed Project would not create a new significant impact or a substantial increase in the severity of previously identified effects that would require the preparation of a subsequent EIR. c) For a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? Less Than Significant Impact/No Changes or New Information Requiring Preparation of an EIR.
The Certified EIR for the Approved Project determined that the closest public airports to Los Alamitos are the Long Beach Airport, approximately three miles west of the city, and the Fullerton Municipal Airport, approximately six miles northeast of the city. However, the airport land use plans for these airports do not extend into the city or its SOI. The Los Alamitos JFTB encompasses nearly the entire southern half of the city.
The JFTB owns two private runways and associated taxiways, hangars, and clear zones. Since the Approved Project does did not include any changes within the base, the base is not designated as a public or public use airport, and there were no public or public use airports in Los Alamitos, there would be no impact from these facilities.
The Certified EIR found that the Approved Project is within JFTB’s Airport Environs Land Use Plan (AELUP) area, and future development in accordance with the General Plan Update would increase or intensify development near the Los Alamitos Army Airfield. However, the Proposed Project is in the northern half of the city and not within JFTB’s AELUP area, which consists only of the JFTB land. Additionally, the Proposed Project would not add additional residential units beyond the maximum 588 that are allowed under the Approved Project. Therefore, the Proposed Project would not expose people residing or working in the area to excessive levels of aircraft- or airport-related noise. A less than significant impact would occur, and no changes nor new information would require the preparation of a subsequent EIR.
5.13.1 Adopted Mitigation Measures Applicable to the Proposed Project The following mitigation measures have been carried through from the Certified EIR. These mitigation measures have been incorporated into the MMRP for this Addendum. 7-1 Individual projects that involve vibration-intensive construction activities—such as blasting, pile drivers, jack hammers, and vibratory rollers—within 200 feet of sensitive receptors shall be evaluated for potential vibration impacts. A study shall be conducted for individual projects where vibration-intensive impacts may occur. If construction-related vibration is determined to be perceptible at vibration-sensitive uses, additional requirements, such as use of lessvibration-intensive equipment or construction techniques, shall be implemented during construction (e.g., nonexplosive blasting methods, drilled piles as opposed to pile driving, etc.). 7-2 Applicants for new development projects within 500 feet of sensitive receptors shall implement the following best management practices to reduce construction noise levels:
Require that construction vehicles and equipment (fixed or mobile) be equipped with properly operating and maintained mufflers.

Restrict haul routes and construction-related traffic Place stock piling and/or vehicle-staging areas as far as practical from residential uses. Replace audible backup warning devices with strobe lights or other warning devices during evening construction activity to the extent permitted by the California Division of Occupational Safety and Health.
Reduce nonessential idling of construction equipment to no more than five minutes Consider the installation of temporary sound barriers for construction activities that are adjacent to occupied noise-sensitive structures, depending on length of construction, type of equipment used, and proximity to noise-sensitive uses.
5.14 POPULATION AND HOUSING
5.14.1 Summary of Impacts Identified in the Certified EIR According to the Certified EIR, the Approved Project would directly induce population and employment growth. However, the General Plan Update accommodates future growth in the city by providing infrastructure and public services to accommodate this growth. Therefore, implementation of the Approved Project would result in a less than significant impact related to population and employment growth.
As concluded in the Certified EIR for the Approved Project, the Approved Project would alter existing land use designations, but was not expected to displace a substantial amount of people and resulted in a less than significant impact.

Less Than Significant Impact/No Changes or New Information Requiring Preparation of an EIR.
As determined in the Certified EIR, the purpose of the General Plan Update was to accommodate future growth in the city. The Proposed Project would amend the existing General Plan Land Use Element to allow for an increase in allowable residential density from 30 units per acre to 60 units per acre on the Project Site, with a maximum of 588 total dwelling units. The development cap is consistent with what is allowed under the Approved Project, and therefore the Proposed Project would not result in the development of additional units beyond what is allowed under the Approved Project. The Proposed Project would be consistent with the Approved Project’s population growth and would not generate substantial, unplanned, population growth. No new or substantially greater impacts would occur. No changes or new information would require preparation of a subsequent EIR.
b) Displace substantial numbers of existing people or housing, necessitating the construction of replacement housing elsewhere?
Less Than Significant Impact/No Changes or New Information Requiring Preparation of an EIR.
The Approved Project would not displace a substantial amount of people. Since the Proposed Project would be limited to a maximum of 588 units, which is consistent with development allowed under the Approved Project, the Proposed Project would not result in the development of additional units. No new or substantially greater impacts would occur. No changes or new information would require preparation of a subsequent EIR.
5.14.3 Adopted Mitigation Measures Applicable to the Proposed Project No mitigation measures related to population and housing were identified in the Certified EIR.
5.15 PUBLIC SERVICES
5.15.1 Summary of Impacts Identified in the Certified EIR According to the Certified EIR, the Approved Project would create additional demand for police services and fire and/or emergency rescue services, but existing regulations ensure that funding is proportional to the increase in population. Any potential future developments would be required to follow existing regulations and, if necessary, apply project-specific mitigation measures. Therefore, the impact was less than significant, and no mitigation measures were required.
Additionally, the Approved Project was expected to lead to new school-aged students, but the students generated from the Approved Project were within the capacity of Los Alamitos Unified School District, and therefore the impacts were less than significant.
The Certified EIR determined that the population growth generated by the Approved Project would be proportional to funding for library services and would therefore result in a less than significant impact to library services.

The Approved Project’s impact to parks was discussed in the Certified EIR under the Recreation topic. The Certified EIR determined that implementation of the Approved Project would not significantly increase the use of parks or lead to substantial physical deterioration of these recreation resources. The Approved Project’s demand for parks and recreational facilities would be adequately served by the existing parkland and was determined to have no impact.

As discussed in the Certified EIR, the Proposed Project would be capped at 588 units, which is consistent with the development envelop of the Approved Project. The Proposed Project would not generate new or additional population beyond the Approved Project and would therefore not require the construction or expansion of recreational facilities. As with the Approved Project, the Proposed Project would not result in significant impacts relating to new or expanded recreational facilities. No new or substantially greater impacts would occur. No changes or new information would require preparation of a subsequent EIR.
5.16.3 Adopted Mitigation Measures Applicable to the Proposed Project No mitigation measures related to parks and recreation were identified in the Certified EIR.
5.17 TRANSPORTATION/TRAFFIC
5.17.1 Summary of Impacts Identified in the Certified EIR The Certified EIR determined that buildout of the Approved Project plus cumulative growth in the region would generate an increase in traffic volumes that would impact levels of service at local area intersections and roadway segments. The Certified EIR concluded that mitigation measures for the three intersections (i.e., Los Alamitos Boulevard and Katella Avenue, Bloomfield Street and Cerritos Avenue, Wallingsford Road/Walnut Street and Katella Avenue) and two roadways (i.e., Katella Avenue and Cerritos Avenue) were infeasible due to right-of-way constraints. Based on the General Plan and the City’s standards for these intersections and roadways, the Certified EIR determined that impacts were significant and unavoidable.
The Certified EIR determined that trip generation related to the Approved Project, in combination with existing and proposed cumulative development, would not result in designated road and/or highways exceeding the congestion management agency service standards. Impacts were less than significant.
The General Plan Update includes policies, plans, and programs for alternative transportation. The Mobility and Circulation Element policies support public transit, bicycle improvements, and improvements to the pedestrian facilities by closing gaps in the network, expanding the network, and coordinating with regional agencies. They are also consistent with regional plans, such as the OCTA Commuter Bikeways Strategic Plan.
Additionally, these policies support implementation of complete streets through a layered network approach, consistent with the state’s Complete Streets Act. Therefore, they are consistent with the existing adopted policies, plans, and programs regarding public transit, bicycle, or pedestrian facilities. Impacts were less than significant.
The Certified EIR found that any future development in accordance with the Approved Project could place additional residential, commercial, and industrial uses near the Los Alamitos Army Airfield. However, the city and the SOI are largely built out, and the land use changes would not change air traffic patterns at JFTB.
Consequently, the Approved Project would not change air traffic patterns, and no impacts would occur.

The Certified EIR found that Approved Project did not propose substantial changes to the city and SOI circulation patterns, such as the redesign or closure of streets. The Approved Project also did not propose to introduce new incompatible uses (e.g., farm equipment) into the city’s circulation system. Therefore, impacts relating to hazards due to a design feature or incompatible uses were less than significant.
The Certified EIR found that the Approved Project would involve the alteration, intensification, and redistribution of land uses in Los Alamitos. However, the city and SOI were generally built out, and the proposed land use changes would not result in substantial changes to the city and SOI circulation patterns or emergency access routes. Therefore, impacts to emergency response plans were less than significant.

allowable density of residential units within a mixed-use area, which would encourage the use of active transportation, such as walking and bicycling, due to the proximity of residential units to commercial use and services.
The development cap is consistent with what is allowed under the Approved Project. Thus, implementation of the Proposed Project would not result in an increase in residential capacity, and no additional traffic would be generated as a result of the Proposed Project. No new or substantially greater impacts would occur. No changes or new information would require preparation of a subsequent EIR. b) Conflict or be inconsistent with CEQA Guidelines § 15064.3, subdivision (b)?

With approval of the discretionary action, the Proposed Project would be consistent with the land use designation for the Project Site. The Proposed Project would remain capped at 588 units and would therefore would not result in the development of additional units beyond what was previously analyzed in the Certified EIR. As with the Approved Project, future development may result in new excavations or earthwork activities that have the potential to unearth tribal cultural resources.
Since the Proposed Project is an Addendum to a General Plan EIR, AB 52 is not required. The City of Los Alamitos sent certified tribal consultation letters pursuant to SB 18 to 18 California Native American tribes.
One response was received from the Gabrieleno Band of Mission Indians–Kizh Nation, who indicated that no consultation was requested for the Proposed Project (see Appendix A, Tribal Consultation). Any future development resulting from the Proposed Project would incorporate all the identified mitigation measures from the Certified EIR. With adherence to Mitigation Measure 3-2, and similar to the Approved Project, the Proposed Project would result in a less than significant impact. No new significant impact or substantial increase in the severity of a previously described impact would occur, and there are no substantial changes in the circumstances or new information that was not known and could not have been known at the time of the adoption of the Certified EIR with respect to Tribal Cultural Resources, and a subsequent EIR is not required.
5.18.3 Adopted Mitigation Measures Applicable to the Proposed Project Refer to Mitigation Measure 3.2 in the Section 5.5, Cultural Resources.
5.19 UTILITIES AND SERVICE SYSTEMS
5.19.1 Summary of Impacts Identified in the Certified EIR The Certified EIR determined that the Approved Project would increase the demand for electricity, natural gas, water, and telephone services. The Approved Project would increase the generation of wastewater, soil waste, and runoff. However, the existing infrastructure had the capacity to service the Approved Project, and any new development would be required to ensure that sufficient infrastructure was available; the impacts were less than significant.

The Certified EIR determined that the existing infrastructure had the capacity to service the Approved Project, any new development consistent with the Approved Project would be required to ensure that sufficient infrastructure was available, and the impacts were less than significant. The Proposed Project would not lead to additional residential units beyond what is allowed under the Approved Project. Therefore, the Proposed Project would not further increase the demand for water, electricity, natural gas, or telecommunication facilities, and it would not generate additional wastewater or stormwater. No new or substantially greater impacts would occur. No changes or new information would require preparation of a subsequent EIR. b) Have sufficient water supplies available to serve the project and reasonably foreseeable future development during normal, dry and multiple dry years?

5. Environmental Analysis
Less Than Significant Impact/No Changes or New Information Requiring Preparation of an EIR.
As determined in the Certified EIR, the Approved Project’s net increase in water demands would be well within the forecast increase in Golden State Water Company’s Water supply, and there would be adequate water supplies to meet demands in single dry years and multiple dry years. Since the Proposed Project would be capped at 588 units, it would not develop units beyond what is allowed under the Approved Project. No new or substantially greater impacts would occur. No changes or new information would require preparation of a subsequent EIR.
c) Result in a determination by the wastewater treatment provider which serves or may serve the project that it has adequate capacity to serve the project’s projected demand in addition to the provider’s existing commitments?
Less Than Significant Impact/No Changes or New Information Requiring Preparation of an EIR.
As determined in the Certified EIR, the forecast increase in wastewater generation under the Approved Project would be within the capacity of the current wastewater treatment provider. Since the Proposed Project would be capped at 588 units, it would not develop units beyond what is allowed under the Approved Project.
Additionally, any new development would be reviewed by Public Works to ensure sufficient sewer capacity. No new or substantially greater impacts would occur. No changes or new information would require preparation of a subsequent EIR.
d) Generate solid waste in excess of state or local standards, or in excess of the capacity of local infrastructure, or otherwise impair the attainment of solid waste reduction goals? Less Than Significant Impact/No Changes or New Information Requiring Preparation of an EIR.
As determined in the Certified EIR, the Approved Project would increase solid waste, but the landfills had adequate capacity for the solid waste generated by the Approved Project. Since the Proposed Project would be capped at 588 units, it would not result in the development of additional units beyond what is allowed under the Approved Project. No new or substantially greater impacts would occur. No changes or new information would require preparation of a subsequent EIR.
e) Comply with federal, state, and local management and reduction statutes and regulations related to solid waste?
No Impact. Any new development within the Approved Project and the Proposed Project would be required to comply with existing codes and regulations related to solid waste. Therefore, no impact would occur, and the Proposed Project would not create a new significant impact or a substantial increase in the severity of previously identified effects.
5.19.3 Adopted Mitigation Measures Applicable to the Proposed Project No mitigation measures related to utilities and service systems were identified in the Certified EIR.

5.20 WILDFIRE
5.20.1 Summary of Impacts Identified in the Certified EIR Wildfire was not analyzed as a separate topic in the prior Certified EIR; however, it was addressed as part of the Hazards and Hazardous Materials section and was scoped out in the Certified EIR. The Certified EIR determined that the City is primarily urban and developed. The Approved Project would not expose people or structures to a significant risk of loss, injury, or death involving wildland fires, including wildland fires that occur on land adjacent to urbanized areas or where residences are intermixed with wildlands. The Certified EIR further determined that the Project Site is not subject to mudflows due to the flat topography.

The Project Site and the City of Los Alamitos are not located near or within a Very High Fire Hazard Severity Zone according to the California Department of Forestry and Fire Protection (CAL FIRE 2011). The Project Site is also not within or near a State Responsibility Area (SRA).
LOS ALAMITOS TOWN CENTER PROJECT EIR ADDENDUM
CITY OF LOS ALAMITOS
5. Environmental Analysis
a) Substantially impair an adopted emergency response plan or emergency evacuation plan? Less Than Significant Impact/No Changes or New Information Requiring Preparation of an EIR.
As identified in the Certified EIR for the Approved Project, there would be no substantial changes to the circulation patterns or emergency access routes. The Proposed Project would not change the circulation patterns or emergency access routes. The Proposed Project is not near or within a Very High Fire Hazard Severity Zone or SRA. Therefore, the Proposed Project would not create a new significant impact or a substantial increase in the severity of previously identified effects. No changes or new information would require preparation of a subsequent EIR.
b) Due to slope, prevailing winds, and other factors, exacerbate wildfire risks, and thereby expose project occupants to pollutant concentrations from a wildfire or the uncontrolled spread of a wildfire?
No Impact. The Proposed Project is in an urban environment and is developed. There are no wildland areas nor wildland interface areas located in the vicinity. Consequently, no wildland fires would affect or be affected by implementation of the Proposed Project. No new or substantially greater impacts would occur, and no changes or new information would require preparation of a subsequent EIR. c) Require the installation or maintenance of associated infrastructure (such as roads, fuel breaks, emergency water sources, power lines or other utilities) that may exacerbate fire risk or that may result in temporary or ongoing impacts to the environment? No Impact. The Proposed Project is in an urban environment and is surrounded by existing development.
Installation or maintenance of associated infrastructures would not exacerbate fire risk or result in temporary ongoing impacts to the environment because no wildland nor wildland interface areas exist at or around the Project Site. The Project Site is not near or within a Very High Fire Hazard Severity Zone or an SRA. No new or substantially greater impacts would occur, and no changes or new information would require preparation of a subsequent EIR.
d) Expose people or structures to significant risks, including downslope or downstream flooding or landslides, as a result of runoff, post-fire slope instability, or drainage changes? No Impact. As discussed in the Certified EIR, the Project Site is primarily flat and located in an urbanized area. The Project Site is not near or within a Very High Fire Hazard Severity Zone or an SRA. Each development project consistent with the Approved Project and Proposed Project would be required to implement low impact development principles and best practices to manage stormwater on-site. The Proposed Project would result in no impact. The Proposed Project would not result in new significant impacts or a substantial increase in the severity of previously identified effects; it is consistent with the Certified EIR and would not require the preparation of a subsequent EIR.
5.20.3 Adopted Mitigation Measures Applicable to the Proposed Project No mitigation measures related to wildfire were identified in the Certified EIR.

Less Than Significant Impact/No Changes or New Information Requiring Preparation of an EIR.
The Proposed Project would amend the existing General Plan to allow for an increase in residential density from 30 units per acre to 60 units per acre, with a development cap of 588 total dwelling units. This development cap is consistent with what is allowed under the Approved Project. The Proposed Project would therefore not result in the development of additional units beyond what is allowed under the Approved Project.
Therefore, the Proposed Project would not result in any new cumulatively considerable impacts or substantially increase the severity of the cumulative effects previously disclosed in the Certified EIR. As demonstrated in this Addendum, the Proposed Project would not result in new significant impacts, nor would it substantially increase the severity of impacts evaluated and determined in the Certified EIR. Because the Proposed Project would not meet any of the criteria identified in Section 15162 of the State CEQA Guidelines requiring preparation of a subsequent or supplemental EIR, an Addendum to the Certified EIR is the appropriate document type for the Proposed Project.

1. Introduction
1.1 PURPOSE OF MITIGATION MONITORING AND REPORTING
PROGRAM
The City of Los Alamitos (City) is the lead agency for the proposed Los Alamitos Town Center Project (Proposed Project) and has developed this Mitigation Monitoring and Reporting Program (MMRP) as a vehicle for monitoring mitigation measures outlined in the EIR Addendum to the Los Alamitos Town Center Project, State Clearinghouse No. 20131210550. As the lead agency, the City is responsible for implementing the MMRP, which has been prepared in conformance with Section 21081.6 of the California Public Resources Code:
(a) When making findings required by paragraph (1) of subdivision (a) of Section 21081 or when adopting a mitigated negative declaration pursuant to paragraph (2) of subdivision (c) of Section 21080, the following requirements shall apply:
(1) The public agency shall adopt a reporting or monitoring program for the changes made to the project or conditions of project approval, adopted in order to mitigate or avoid significant effects on the environment. The reporting or monitoring program shall be designed to ensure compliance during project implementation. For those changes which have been required or incorporated into the project at the request of a responsible agency or a public agency having jurisdiction by law over natural resources affected by the project, that agency shall, if so requested by the lead or responsible agency, prepare and submit a proposed reporting or monitoring program. (2) The lead agency shall specify the location and custodian of the documents or other material which constitute the record of proceedings upon which its decision is based.
The MMRP consists of mitigation measures that avoid, reduce, and/or fully mitigate potential environmental impacts. The mitigation measures have been identified and recommended through preparation of the MND and drafted to meet the requirements of California Public Resources Code, Section 21081.6.
1.2 PROJECT CHARACTERISTICS
1.2.1 Project Location
City of Los Alamitos is in northwest Orange County and well connected to the region by Interstate (I-) 605 and I-405. The Proposed Project is the Town Center Mixed Use District (Project Site) near the intersection of Los Alamitos Boulevard and Katella Avenue near the northwest side of the City of Los Alamitos. The Project Site is generally bound by Florista Street to the north, Reagan Street and multi-family residential to the east, Farquhar Avenue to the south, and Los Alamitos Boulevard and Chestnut Street to the west.
LOS ALAMITOS TOWN CENTER PROJECT EIR ADDENDUM MITIGATION MONITORING AND REPORTING PROGRAM
CITY OF LOS ALAMITOS
1. Introduction
1.2.2 Project Description
The proposed Town Center Strategic Plan describes the desired development pattern for the properties and public rights-of-way encompassed within the existing Project Site, including streetscape improvements and desired mix of land uses. The Town Center Strategic Plan recommends a multiyear list of actions needed to implement the desired vision for the Project Site. The Town Center Strategic Plan provides recommendations for future actions, but it is an informational document that in and of itself does not constitute a project under CEQA (see CEQA Guidelines Section 15262, Feasibility and Planning Studies). One of its recommendations is a general plan amendment to increase the allowable residential density on the Project Site. The general plan amendment is considered a project under CEQA and is the focus of this Addendum.
The Proposed Project amends the General Plan Land Use Element to increase allowed residential density on the existing Project Site from the existing 30 units per acre to 60 units per acre, with an overall development cap for the Project Site of 588 net new residential units. The development cap of 588 units is within the overall adopted General Plan limits for the Project Site and within the scope of what is evaluated in the Certified EIR.
Therefore, the Proposed Project would not increase residential development beyond what is allowed under the General Plan and Certified EIR (Approved Project).

AIR QUALITY
2-1 If, during subsequent project-level environmental review, constructionrelated criteria air pollutants are determined to have the potential to exceed the South Coast Air Quality Management District (SCAQMD) adopted thresholds of significance, the City of Los Alamitos shall require that applicants for new development projects incorporate mitigation measures as identified in the CEQA document prepared for the project to reduce air pollutant emissions during construction activities. Mitigation measures that may be identified during the environmental review include but are not limited to:
• Using construction equipment rated by the United States Environmental Protection Agency as having Tier 3 (model year 2006 or newer) or Tier 4 (model year 2008 or newer) emission limits, applicable for engines between 50 and 750 horsepower. • Ensuring construction equipment is properly serviced and maintained to the manufacturer’s standards.
• Limiting nonessential idling of construction equipment to no more than five consecutive minutes.
• Water all active construction areas at least three times daily, or as often as needed to control dust emissions. Watering should be sufficient to prevent airborne dust from leaving the site. Increased watering frequency may be necessary whenever wind speeds exceed 15 miles per hour. Reclaimed water should be used whenever possible.
• Cover all trucks hauling soil, sand, and other loose materials or require all trucks to maintain at least two feet of freeboard (i.e., the minimum required space between the top of the load and the top of the trailer).
• Pave, apply water three times daily or as often as necessary to control dust, or apply (non-toxic) soil stabilizers on all unpaved access roads, parking areas, and staging areas at construction sites.

• Sweep daily (with water sweepers using reclaimed water if possible), or as often as needed, all paved access roads, parking areas, and staging areas at the construction site to control dust. • Sweep public streets daily (with water sweepers using reclaimed water if possible) in the vicinity of the Project Site, or as often as needed, to keep streets free of visible soil material.
• Hydroseed or apply non-toxic soil stabilizers to inactive construction areas.
• Enclose, cover, water three times daily, or apply non-toxic soil binders to exposed stockpiles (dirt, sand, etc.).
2-2 New industrial or warehousing land uses that: 1) have the potential to generate 40 or more diesel trucks per day and 2) are located within 1,000 feet of a sensitive land use (e.g. residential, schools, hospitals, nursing homes), as measured from the property line of the project to the property line of the nearest sensitive use, shall submit a health risk assessment (HRA) to the City of Los Alamitos prior to future discretionary project approval. The HRA shall be prepared in accordance with policies and procedures of the state Office of Environmental Health Hazard Assessment and the applicable air quality management district. If the HRA shows that the incremental cancer risk exceeds ten in one million (I0E-06), particulate matter concentrations would exceed 2.5 μg/m3, or the appropriate noncancer hazard index exceeds 1.0, the applicant will be required to identify and demonstrate that best available control technologies for toxics (T-BACTs) are capable of reducing potential cancer and noncancer risks to an acceptable level, including appropriate enforcement mechanisms. TBACTs may include, but are not limited to, restricting idling onsite or electrifying warehousing docks to reduce diesel particulate matter, or requiring use of newer equipment and/or vehicles. T-BACTs identified in the HRA shall be identified as mitigation measures in the environmental document and/or incorporated into the site development plan as a component of the project.

Code Section 5024.1, Title 14 CCR, Section 4852), mitigation shall be identified within the technical study that ensures the value of the historic resource is maintained. 3-2 Applicants for future development projects that require grading of undisturbed soil in areas of known or inferred archaeological resources, prehistoric or historic, shall provide a technical cultural resources assessment to the City of Los Alamitos prior to the issuance of grading permits. The cultural resources assessment shall be prepared by a qualified archaeologist to assess the cultural and historical significance of any known archaeological resources on or next to each respective development site, and to assess the sensitivity of sites for buried archaeological resources. On properties where resources are identified, or that are determined to be moderately to highly sensitive for buried archaeological resources, such studies shall provide a detailed mitigation plan, including a monitoring program and recovery and/or in situ preservation plan, based on the recommendations of a qualified cultural preservation expert. The mitigation plan shall include the following requirements:
a. An archaeologist shall be retained for the development project and shall be on call during grading and other significant grounddisturbing activities. b. Should any cultural/scientific resources be discovered, no further grading shall occur in the area of the discovery until the Community Development Director concurs in writing that
adequate provisions are in place to protect these resources. c. Unanticipated discoveries shall be evaluated for significance by an Orange County Certified Professional Archaeologist. If significance criteria are met, then the project shall be required to perform data recovery, professional identification, radiocarbon dates as applicable, and other special studies; submit materials to the California State University, Fullerton; and provide a comprehensive final report including appropriate records for the California Department of Parks and Recreation (Building, Project applicants of

• Work with local and regional agencies to install appropriate recharging stations to support the use of electric vehicles. Work with developers to install recharging stations at appropriate activity and employment centers to support electric vehicle use. • Conduct energy audits on all City facilities and incorporate costeffective measures to increase energy efficiency. • Public education on energy conservation. Coordinate with local utilities to provide energy conservation information to the public. • Promote energy-efficient design features such as appropriate site orientation, renewable energy systems, use of lighter color roofing and building materials, and passive ventilation and cooling techniques.
• Seek grants and other outside funding for energy efficiency improvements to public or private facilities and structures. • Work with the Los Alamitos Unified School District, the City of Seal Beach, and Rossmoor to obtain grant funding, conduct planning, and construct new and improved existing bicycle and pedestrian facilities to provide safe routes to schools. • Remove barriers that discourage active pedestrian and bicycle routes. Expand facilities and amenities that encourage active routes, such as increasing the number of Class II bike lanes along potential school routes, particularly those that parallel Los Alamitos Boulevard and Katella Avenue.
• Create and implement a pedestrian and bicycle master plan to identify improvements, timing, and funding mechanisms.
• Identify funding and design options for bicycle and pedestrian signage along bicycle routes, in the downtown, and at key trailheads or connection points, with an emphasis on connections to schools and the downtown. Bicycle signage should be
consistent with signs of neighboring jurisdictions, yet distinct for Los Alamitos.

• Coordinate with neighboring jurisdictions on improving connections to existing and planning future bicycle and pedestrian trails.
• Work with OCTA and local businesses to enhance bus stops in Los Alamitos and Rossmoor.
• Coordinate with OCTA on its Long Range Transportation Plan to design bus rapid transit service and stop locations along Katella Avenue.
• Explore the use of parking meters along public streets and on City-owned lots, especially in the downtown.
Identify opportunities for bicycle parking in the downtown, including the conversion of single parallel parking spaces along smaller side streets into on-street or curb-adjacent bicycle parking. Bike racks should serve as functional public art and can reflect the types of businesses or uses.
NOISE
7-1 Individual projects that involve vibration-intensive construction activities—such as blasting, pile drivers, jack hammers, and vibratory rollers—within 200 feet of sensitive receptors shall be evaluated for potential vibration impacts. A study shall be conducted for individual projects where vibration-intensive impacts may occur. If constructionrelated vibration is determined to be perceptible at vibration-sensitive uses, additional requirements, such as use of less-vibration-intensive equipment or construction techniques, shall be implemented during construction (e.g., nonexplosive blasting methods, drilled piles as opposed to pile driving, etc.).

7-2 Applicants for new development projects within 500 feet of sensitive receptors shall implement the following best management practices to reduce construction noise levels:
• Require that construction vehicles and equipment (fixed or mobile) be equipped with properly operating and maintained mufflers.
• Restrict haul routes and construction-related traffic • Place stock piling and/or vehicle-staging areas as far as practical from residential uses.
• Replace audible backup warning devices with strobe lights or other warning devices during evening construction activity to the extent permitted by the California Division of Occupational Safety and Health.
• Reduce nonessential idling of construction equipment to no more than five minutes
Consider the installation of temporary sound barriers for construction activities that are adjacent to occupied noisesensitive structures, depending on length of construction, type of equipment used, and proximity to noise-sensitive uses.
