Included in this analysis are three alternatives, including the CEQA-required “no project” alternative, that involve changes to the project that may reduce the project-related environmental impacts as identified in this EIR. Alternatives have been developed to provide a reasonable range of options to consider that would help decision makers and the public understand the general implications of revising or eliminating certain components of the 2045 General Plan Update.
The following alternatives are evaluated in this EIR:
Alternative 1: No Project Alternative
Alternative 2: Infill Only Alternative
Alternative 3: Greater Annexation Alternative
Alternatives
Final Environmental Impact Report 6-3
Detailed descriptions of the alternatives are included in the impact evaluation for each alternative.
The potential environmental impacts of each alternative are discussed in Section 6.2 through Section 6.4. As required by CEQA, this section also includes a discussion of the “environmentally superior alternative” among those studied, included as Section 6.5 and summarized in Table 6-1.
6.2 Alternative 1: No Project Alternative
6.2.1 Description
Under the No Project Alternative, the City of Santa Maria would not adopt the 2045 General Plan Update. Instead, development would continue in accordance with the existing General Plan. This alternative assumes that current land use designations, policies, and growth projections would remain in effect, guiding future development and infrastructure decisions. For the purpose of this analysis, the No Project Alternative is assumed to result in reduced overall buildout potential compared to the 2045 General Plan Update, as it reflects continuation of existing land use designations and policies without the proposed changes that would facilitate additional growth.
While some development would still occur under existing entitlements and zoning regulations, the City would not implement the new land use strategies, environmental protections, or housing and mobility policies in the plan. As a result, the No Project Alternative would not fulfill the objectives of the 2045 General Plan Update because it would not fully address evolving community needs, state housing requirements (future RHNA cycles), or infrastructure demands anticipated through 2045.
However, as discussed in detail in Section 6.2.2, this alternative would avoid the potential environmental impacts associated with the increased development intensity and expanded planning strategies in the plan.
6.2.2 Impact Analysis
a. Agricultural Resources
With reduced buildout potential compared to the 2045 General Plan Update, the No Project Alternative would place less development pressure on agricultural lands, resulting in reduced impacts to agricultural resources. The No Project Alternative would continue growth in accordance with the existing General Plan and as such, would not extend growth into tracts of Prime Farmland, Farmland of Statewide Importance, or Unique Farmland in the annexation area. In addition, the No Project Alternative would not result in new land use changes on agricultural plans within the city or the annexation area, which includes Prime Farmland and Williamson Act lands. Therefore, the No Project Alternative would have reduced impacts compared to the 2045 General Plan Update.
Overall, the No Project Alternative would reduce impacts to agricultural resources to a less than significant level.
b. Air Quality and Greenhouse Gas Emissions
Air Quality: The lower level of development anticipated under the No Project Alternative would generate reduced vehicle trips and less energy use, resulting in reduced impacts on air quality and GHG emissions. However, the No Project Alternative would not implement the policies from the plan that aim to maintain air quality and protect public health in Santa Maria. Furthermore, this alternative would not be required to implement Mitigation Measures AQGHG-1 and AQGHG-2, which aim to reduce construction-related air pollutant emissions by requiring future development in City of Santa Maria
2045 General Plan Update
6-4
Santa Maria to implement best management practices consistent with Santa Barbara County Air Pollution Control District (SBCAPCD) guidelines and require construction projects to utilize Tier 3 equipment of higher to reduce construction related TAC exposure. Similar to the 2045 General Plan Update, construction facilitated by the No Project Alternative has the potential to emit fugitive dust and criteria air pollutants that exceed SBCAPCD’s standards. As such, impacts related to air quality would be reduced compared to the 2045 General Plan Update but would remain significant and unavoidable as fugitive dust and criteria air pollutant emissions from the No Project Alternative may still exceed SBCAPCD’s standards.
Greenhouse Gas Emissions: The No Project Alternative would be generally consistent with the goals of the 2045 General Plan Update since future development would be required to comply with the latest Title 24 Green Building Code and Building Efficiency Energy Standards and applicable State law. However, the No Project Alternative would not include new policies aimed at reducing GHG emissions within the city. While development would be reduced in comparison to the 2045 General Plan Update, there is no assurance that the No Project Alternative would be consistent with the State-wide target of net-zero GHG emissions by 2045. While impacts would be reduced compared to the 2045 General Plan Update, impacts related to GHG emissions would remain significant and unavoidable due to potential inconsistencies with the State-wide target. c. Biological Resources
Less growth and development outside of the existing urban footprint city boundary under the No Project Alternative would reduce the potential for habitat disturbance, leading to reduced impacts to biological resources. However, the No Project Alternative would not implement the policies from the 2045 General Plan Update that aim to enhance the protection of biological resources, such as development review and critical habitat protection. Specifically, the No Project Alternative would not implement Mitigation Measures BIO-1(a) through BIO-1(k), which require future development to avoid, minimize, or offset impacts to sensitive species and habitats through surveys, construction buffers, habitat restoration, and compliance with agency regulations. As a result, development facilitated by the No Project Alternative has the potential to disturb special status plant species, endangered/threatened animal species, and important habitat. As a result, development facilitated by the No Project Alternative would have a greater potential to adversely affect biological resources compared to the 2045 General Plan Update, and overall impacts to biological resources would be significant and unavoidable.
d. Cultural and Tribal Cultural Resources
Cultural Resources: Given its lower buildout potential, the No Project Alternative would involve less ground disturbance overall and therefore reduce the likelihood of impacting cultural and tribal cultural resources. However, the No Project Alternative would not implement the policies from the 2045 General Plan Update that aim to protect historical and culturally significant resources. In the absence of new policies to protect historical and culturally significant resources or the plan-level mitigation measures associated with the 2045 General Plan Update, the No Project Alternative would be required to implement mitigation on a project-by-project basis. As a result, potential impacts to historical and culturally significant resources would be greater than under the 2045 General Plan Update, and would be significant and unavoidable.
Archaeological Resources: The No Project Alternative would result in reduced buildout potential compared to the 2045 General Plan Update and therefore have less potential to disturb subsurface archaeological resources. However, this alternative would not implement the policies from the 2045 Alternatives
Final Environmental Impact Report 6-5
General Plan Update that would require archaeological resources assessments or implement unanticipated discovery procedures for development involving ground-disturbing activities. In the absence of new policies to prevent the disturbance of subsurface archaeological resources, the potential for the No Project Alternative to substantially disturb archaeological resources is higher than the 2045 General Plan Update and would need to implement mitigation in order to reduce impacts to a less than significant level. In addition, the No Project Alternative would not implement Mitigation Measures CUL-1 through CUL-4(b), which aim to protect archaeological and historical resources by requiring pre-construction surveys, construction monitoring, and procedures for the treatment of any discovered resources, necessary for reducing impacts. Therefore, potential impacts to cultural impacts under this alternative would be greater than under the 2045 General Plan Update .
Tribal Cultural Resources: Similar to the 2045 General Plan Update, development facilitated by the No Project Alternative would be subject to the requirements of AB 52 and if required, SB 18.
However, the No Project Alternative would not implement Mitigation Measures CUL-4(a) and CUL- 4(b), which ensure tribal consultation and protection of tribal cultural resources through construction monitoring by tribal representatives and protocols for the discovery and treatment of tribal resources, and thus would not ensure project-specific tribal cultural resource identification and consultation, and the appropriate avoidance, minimization, or mitigation. In the absence of new policies to protect tribal cultural resources or the plan-level mitigation measures associated with the 2045 General Plan Update, the No Project Alternative would have greater impact on tribal cultural resources as the 2045 General Plan Update. Future development under the No Project Alternative would be required to implement mitigation measures to avoid or minimize impacts to tribal cultural resources. Therefore, potential impact to tribal cultural resources would be greater than under the 2045 General Plan Update, and would be significant and unavoidable. e. Hydrology and Water Quality
Compared to the 2045 General Plan Update, the No Project Alternative would introduce reduced impervious surfaces and require reduced infrastructure extensions, reducing potential impacts on hydrology and water quality. Under the No Project Alternative, fewer residential units would be developed compared to the 2045 General Plan Update, consistent with existing land use designations and zoning. Ground-disturbing construction activities that could potentially affect water quality from sedimentation or accidental spills would occur following current adopted zoning.
Any changes related to hydrology, water quality, watersheds and drainage patterns, flood and inundation hazards, and ground water resource management caused by changes in existing development would follow the currently adopted standards. Therefore, the No Project Alternative impacts related to hydrology and water quality would be less than significant, similar to the 2045 General Plan Update.
f. Noise
Although the No Project Alternative would involve less overall development than the 2045 General Plan Update, resulting in reduced construction activity and traffic volumes, its lack of policies and mitigation to address noise and vibration would ultimately lead to greater noise impacts. The No Project Alternative would not implement the policies from the 2045 General Plan Update that aim to promote land uses compatible with future noise levels or minimize transportation noise and other intermittent noise. In addition, the No Project Alternative would not implement Mitigation Measures NOI-1(a), NOI-1(b), or NOI-2, which require construction activities to follow noise- City of Santa Maria
2045 General Plan Update
6-6
reduction practices to minimize noise impacts on nearby sensitive receptors. Without implementation of these mitigation measures, potential construction and operation noise impacts would remain significant and unavoidable, and potential impacts from construction groundborne vibration would change from less than significant to significant and unavoidable. Therefore, overall noise impacts induced by the No Project Alternative would have slightly greater impacts than the 2045 General Plan Update related to construction noise, operational noise, and construction groundborne vibration. These impacts would be significant and unavoidable. g. Transportation and Traffic
Lower buildout under the No Project Alternative would result in reduced daily trips and reduced roadway congestion compared to the 2045 General Plan Update. The No Project Alternative would not implement the goals and policies included in the 2045 General Plan Update to reduce VMT, including the promotion of different modes of transportation including transit and active transportation. Unlike the 2045 General Plan Update, the No Project Alternative would not place an emphasis on mixed-use and infill development in Santa Maria. Without policies to guide mixed-use and infill development, it is anticipated that regional VMT would increase as residents and employees commute longer distances. Therefore, the No Project Alternative would have slightly greater impacts on VMT, and impacts would remain significant and unavoidable h. Utilities and Service Systems
As a result of the reduced development intensity, the No Project Alternative would generate lower demand on water, wastewater, energy, and solid waste systems. However, the No Project Alternative would not implement the policies included in the 2045 General Plan Update that aim to ensure citywide utility infrastructure supports development. As a result, overall demand would be lower, the absence of utilities planning and infrastructure policies could limit the City’s ability to manage utility impacts efficiently. In addition, the No Project Alternative would not include the annexation area, unlike the 2045 General Plan Update. Therefore, the No Project Alternative would not require the establishment of new or expanded utilities infrastructure in order to service the city’s expansion. Similar to the 2045 General Plan Update, development facilitated by the No Project Alternative would be required to comply with all applicable federal, State, and local regulations regarding water, wastewater, and waste disposal. Therefore, impacts would be slightly reduced overall due to lower development levels when compared to the 2045 General Plan and would remain less than significant.
6.3 Alternative 2: Infill Only Alternative
6.3.1 Description
Under the Infill Only Alternative, the City of Santa Maria would adopt the 2045 General Plan Update, including all goals and policies. However, the Infill Only Alternative would exclude the annexation of areas located east of the current City limits and direct development to areas within existing urban or suburban areas as infill, redevelopment, or increased densities. For the purpose of this analysis, the Infill Only Alternative is assumed to result in a similar overall level of buildout and population growth compared to the 2045 General Plan Update, despite the exclusion of future development in the eastern annexation area. Therefore, this analysis assumes that the Infill Only Alternative would result in the addition of approximately 16,000 new residential units and up to 23,750 new jobs associated with new commercial development within city limits.
Alternatives
Final Environmental Impact Report 6-7
While this alternative would reduce the geographic footprint of development, it would result in increased development pressure on existing neighborhoods and infrastructure. As a result, the Infill Only Alternative may not fulfill the primary objectives of the 2045 General Plan Update because it would not fully address evolving community health needs, state housing requirements, or opportunities for connected growth anticipated through 2045. However, as discussed in detail in Section 6.3.2, this alternative would avoid environmental impacts in the annexation area, such as conversion of agricultural land, fragmentation of open space, or potential effects on biological resources, while potentially exacerbating environmental impacts associated with the increased development density in existing neighborhoods.
6.3.2 Impact Analysis
a. Agricultural Resources
By accommodating a similar amount of development entirely within existing City limits, the Infill Only Alternative would avoid the annexation area’s agricultural lands and result in reduced impacts to farmland. While the Farmland Mapping and Monitoring Program still designates areas within the city as Important Farmland, the conversion of these areas and associated land use changes have been previously evaluated in earlier environmental documents which are listed in Section 4.1, Agricultural Resources. Under this alternative, future growth would rely on redevelopment and increased densities within existing urbanized areas and locations already designated for urban development rather than expansion into agricultural lands. The Infill Only Alternative would not convert agricultural lands within city limits because lands within city limits currently used for agricultural purposes have been previously designated for planned urban redevelopment in specific plans or earlier iterations of the General Plan. As discussed in Section 4.1, Agricultural Resources, environmental documents such as the Sphere of Influence Expansion Environmental Impact Report (SCH #90010930), the Area 9 Specific Plan Environmental Impact Report (SCH #2008071018), the Blosser-Southeast Specific Plan Amendment Supplemental Environmental Impact Report (SCH #1994107909),and the Betteravia Plaza General Plan Amendment, Land Use and Zone Change and Development Agreement Environmental Impact Report (SCH #2015011029) have evaluated impacts to agricultural resources from the conversion of agricultural lands within the city. As a result, these lands have land use and zoning designations intended for urban redevelopment and would not be considered a conversion of existing agricultural uses. The exclusion of future development in the eastern annexation area would reduce impacts to agricultural resources in comparison to the 2045 General Plan Update. However, because this alternative limits development to infill sites, it would constrain opportunities for housing diversity and connected growth compared to the proposed plan.
As the Infill Only Alternative would not result in the conversion of agricultural lands within City limits nor would it include the annexation area, this impact would be reduced to less than significant. b. Air Quality and Greenhouse Gas Emissions
Air Quality: The Infill Only Alternative assumes a similar level of buildout and a more compact development pattern, which together would help lower GHG emissions and vehicle-related air pollutants. This infill-oriented growth pattern would be more compact, reducing VMT per capita and enhancing opportunities for walking, biking, and transit use, potentially reducing criteria air pollutant and GHG emissions on a per capita basis. However, similar to the 2045 General Plan Update, the Infill Only Alternative would still have the potential to exceed SBCAPCD standards related to fugitive dust and criteria air pollutants. Therefore, implementation of Mitigation Measures AQGHG-1 and AQGHG-2, which aim to reduce construction-related air pollutant City of Santa Maria
2045 General Plan Update
6-8
emissions by requiring future development in Santa Maria to implement best management practices consistent with SBCAPCD standards and use of Tier 3 or higher construction equipment, would be required. As such, impacts related to air quality would be reduced compared to the 2045 General Plan Update but would remain significant and unavoidable as fugitive dust and criteria air pollutant emissions from the Infill Only Alternative may still exceed SBCAPCD’s standards.
Greenhouse Gas Emissions: While a more compact development pattern may support GHG reduction strategies, the City may still not achieve consistency with the statewide target of net-zero GHG emissions by 2045, and no feasible mitigation is available to reduce this impact to a less than significant level. Therefore, impacts associated with GHG emissions would be reduced compared to the 2045 General Plan Update, but would remain significant and unavoidable. c. Biological Resources
Although total development would be similar to the proposed plan, growth under this alternative would be focused in previously urbanized or disturbed areas, resulting in less impact to natural habitats and biological resources overall. This could result in reduced impacts to biological resources, including habitat for special-status species potentially present in the eastern annexation area. Similar to the 2045 General Plan Update, the Infill Only Alternative would implement policies to enhance protection of biological resources, including development review and habitat conservation strategies. In addition, the Infill Only Alternative would implement Mitigation Measures BIO-1(a) through BIO-1(k), which require future development to avoid, minimize, or offset impacts to sensitive species and habitats through surveys, construction buffers, habitat restoration, and compliance with agency regulations. This would reduce potentially significant impacts to a less than significant level. As a result, impacts to biological resources would be reduced compared to the 2045 General Plan Update, and would be less than significant with mitigation incorporated. d. Cultural and Tribal Cultural Resources
While overall buildout would be similar to the proposed plan, the infill-focused growth pattern would focus development within existing City limits, where land is already disturbed. Development of previously disturbed lands would reduce the potential for disturbing previously unidentified cultural and tribal cultural resources, particularly in comparison to development of the annexation area identified in the 2045 General Plan Update. Similar to the 2045 General Plan Update, the Infill Only Alternative would implement General Plan policies that aim to protect cultural and archaeological resources and would incorporate Mitigation Measures CUL-1 through CUL-4(b) as deemed necessary by the City, which aim to protect archaeological and historical resources by requiring pre-construction surveys, construction monitoring, and procedures for the treatment of any discovered resources. Implementation of these mitigation measures would reduce potential impacts to cultural resources to a less than significant level. The Infill Only Alternative would also comply with AB 52 and SB 18, and would implement Mitigation Measures CUL-4(a) and CUL-4(b), which ensure tribal consultation and protection of tribal cultural resources through construction monitoring by tribal representatives and protocols for the discovery and treatment of tribal resources. This would reduce potential impacts to tribal cultural resources to a less than significant level. Consequently, impacts to cultural and tribal cultural resources would be reduced compared to the 2045 General Plan Update and would remain less than significant with mitigation.
Alternatives
Final Environmental Impact Report 6-9
e. Hydrology and Water Quality
Because it directs growth to areas with existing drainage infrastructure, the Infill Only Alternative would reduce impacts to hydrology and water quality. As a result, impacts to hydrology and water quality would remain similar overall, but would be more focused within already urbanized areas.
Unlike the 2045 General Plan Update, the Infill Only Alternative would not develop open space or agricultural lands to the east of the City, thereby avoiding new impervious surfaces in greenfield areas and reducing potential impacts on undeveloped drainage systems and natural waterways.
Similar to the 2045 General Plan Update, development under the Infill Only Alternative would be required to adhere to existing NPDES permits and municipal code requirements. In addition, the Infill Only Alternative would implement policies that aim to protect groundwater supplies, groundwater recharge, and reduce impacts due to the release of pollutants from inundation.
Because this alternative would focus on redevelopment and infill, stormwater improvements would be focused on upgrades to existing drainage infrastructure rather than extending new systems.
Development under the Infill Only Alternative would comply with all federal, State, and local regulations to minimize water quality impacts and would not conflict with the Basin Plan. Therefore, impacts related to hydrology and water quality would be similar to those of the 2045 General Plan Update and would remain less than significant.
f. Noise
Although the scale of development would be similar to the proposed plan, infill development would occur in areas already exposed to urban activity, resulting in similar or slightly lower noise impacts overall. Construction-related noise could affect adjacent residences, schools, or care facilities located near infill sites. The Infill Only Alternative would implement policies aimed at reducing construction and operational noise, as well as groundborne vibration. Development facilitated by the Infill Only Alternative is expected to result in similar stationary noise and groundborne vibration levels as the 2045 General Plan Update. The Infill Only Alternative would include Mitigation Measures NOI-1(a) and NOI-1(b), which set conditions of approval for all development within 500 feet of a sensitive receptor and implementing roadway vehicle noise reduction measures. Focusing growth in already developed areas may also increase the likelihood of cumulative noise impacts along major corridors, such as Broadway and Main Street, due to traffic increases. However, similar to the 2045 General Plan Update, there would be no feasible mitigation that could avoid or fully mitigate the increase in construction and traffic noise in the plan area. As a result, potential construction noise impacts and operational traffic noise impacts would remain significant and unavoidable. Implementation of Mitigation Measure NOI-2, which requires construction vibration control measures to be incorporated, would reduce construction vibration impacts to a less than significant level. Overall, noise impacts would be similar to those of the 2045 General Plan Update and would remain significant and unavoidable.
g. Transportation and Traffic
Due to a more centralized pattern of growth, even with similar development levels, the Infill Only Alternative would result in reduced vehicle miles traveled and reduced congestion. This compact development pattern could reduce average trip lengths and improve access to services and jobs, particularly in areas already served by Santa Maria Area Transit (SMAT) and the city’s active transportation network. Similar to the 2045 General Plan Update, the Infill Only Alternative would not conflict with the Connected 2050 RTP/SCS, the Santa Maria Active Transportation Plan, or any other applicable transportation plan or policy. Development facilitated by the Infill Only Alternative City of Santa Maria
2045 General Plan Update
6-10
would comply with State, Santa Maria Fire Department, and City requirements related to transportation design safety and emergency access. While the more compact pattern could slightly improve per capita VMT compared to the 2045 General Plan Update, the City as a whole would still not meet the 17 percent VMT reduction threshold required by SBCAG. Therefore, this impact would be slightly reduced over the 2045 General Plan Update but would still remain significant and unavoidable.
h. Utilities and Service Systems
While utility demand would be similar to the proposed plan, the Infill Only Alternative would allow for more efficient use of existing infrastructure within the City. Concentrating growth within City limits has the potential to improve service efficiency and reduce the need for new infrastructure extensions into greenfield areas. However, existing facilities may still require upgrades or capacity expansions to serve new development in the City limit. Like the 2045 General Plan Update, the Infill Only Alternative would be subject to applicable State and local requirements, and would be required to implement policies to ensure adequate public services. Therefore, impacts to utilities and service systems would be similar to those of the 2045 General Plan Update and would be less than significant with implementation of policies and mitigation measures.
6.4 Alternative 3: Greater Annexation Alternative
6.4.1 Description
Under the Greater Annexation Alternative, the City of Santa Maria would adopt the 2045 General Plan Update, including all goals, policies, and land use changes. However, the Greater Annexation Alternative would include a larger annexation area east of the current City limits. This alternative assumes a similar level of development density would occur in the larger annexation area, resulting in increased total development and an increased population compared to the 2045 General Plan Update. For the purpose of this analysis, the Greater Annexation Alternative is assumed to result in increased overall buildout potential and population growth compared to the 2045 General Plan Update, due to the inclusion of a larger annexation area and expanded Sphere of Influence.
The expanded geographic footprint of the Greater Annexation Alternative would fulfill many of the primary objectives of the 2045 General Plan Update because it would have the capacity to meet state housing requirements and address some community needs; however, the distributed development that may occur under this alternative would not fully address evolving community health needs or opportunities for connected growth anticipated through 2045. However, as discussed in detail in Section 6.4.2, this alternative would result in greater environmental impacts across many resource areas as the increased footprint would reduce available agricultural land and increase VMT and associated criteria pollutant and GHG emissions.
6.4.2 Impact Analysis
a. Agricultural Resources
The Greater Annexation Alternative would allow for greater overall buildout than the proposed plan by expanding the annexation area, leading to increased impacts from the conversion of agricultural land. As a result, additional agricultural lands would potentially be converted to non-agricultural uses, including additional Prime Farmland outside City limits. Similar to the 2045 General Plan Alternatives
Final Environmental Impact Report 6-11
Update, the Greater Annexation Alternative would require the implementation of policies and actions of the 2045 General Plan Update which aim to reduce potential impacts related to the conversion of agricultural lands and conflicts with agricultural zoning. However, due to increased conversion of agricultural lands within the greater annexation area, impacts to agricultural resources would be greater and would remain significant and unavoidable. b. Air Quality and Greenhouse Gas Emissions
Air Quality: Under the Greater Annexation Alternative, higher levels of growth and a more dispersed development pattern would increase vehicle miles traveled and emissions, resulting in greater impacts to air quality and greenhouse gases. Under this alternative, growth would be more widespread, thereby increasing VMT per capita and reducing potential active transportation and transit uses. As such, mobile emissions of criteria air pollutants and GHGs would increase relative to the 2045 General Plan Update. Similar to the 2045 General Plan Update, the Greater Annexation Alternative would have the potential to exceed SBCAPCD standards related to fugitive dust and criteria air pollutants. Therefore, implementation of Mitigation Measures AQGHG-1 and AQGHG-2, which aim to reduce construction-related air pollutant emissions, would be required. Although implementation would serve to reduce construction-related air pollutant emissions, air pollutant emissions under this alternative would be greater than the 2045 General Plan Update and impacts would remain significant and unavoidable.
Greenhouse Gas Emissions: The increased development potential would also increase GHG emissions and as such, the City may not achieve consistency with the statewide target of net-zero GHG emissions by 2045, and no feasible mitigation is available to reduce this impact to a less than significant level. Therefore, impacts regarding GHG emissions would be greater than the 2045 General Plan Update, and would remain significant and unavoidable. c. Biological Resources
With additional development in new areas outside the existing City limits, the Greater Annexation Alternative would increase the likelihood of disturbing sensitive biological resources. This alternative would increase the potential for impacts to biological resources, particularly in areas that support sensitive natural communities, wetlands, and habitat for special-status species within agricultural and open space areas of the larger annexation area. However, similar to the 2045 General Plan Update, the Greater Annexation Alternative would implement policies to protect biological resources, including habitat conservation strategies and development review procedures.
Additionally, this alternative would implement Mitigation Measures BIO-1(a) through BIO-1(k), which require future development to avoid, minimize, or offset impacts to sensitive species and habitats through surveys, construction buffers, habitat restoration, and compliance with agency regulations. This would reduce potentially significant impacts to a less than significant level. As such, while the Greater Annexation Alternative could result in greater biological resource impacts compared to the 2045 General Plan Update, impacts to biological resources would remain less than significant with mitigation incorporated.
d. Cultural and Tribal Cultural Resources
The expansion into previously undeveloped areas, combined with higher buildout potential, would increase the potential to affect previously undisturbed cultural and tribal resources under the Greater Annexation Alternative. As this alternative would have the potential to disturb a larger footprint and an increased area of previously undeveloped land, this alternative would result in a City of Santa Maria
2045 General Plan Update
6-12
greater potential to disturb previously unidentified cultural and tribal cultural resources. Similar to the 2045 General Plan Update, the Greater Annexation Alternative would implement General Plan policies to protect cultural and archaeological resources and would incorporate Mitigation Measures CUL-1 through CUL-4(b), which aim to protect archaeological and historical resources by requiring pre-construction surveys, construction monitoring, and procedures for the treatment of any resources discovered. These measures would reduce impacts to a less than significant level. The Greater Annexation Alternative would also comply with AB 52 and SB 18, and implement Mitigation Measures CUL-4(a) and CUL-4(b), which ensure tribal consultation and protection of tribal cultural resources through construction monitoring by tribal representatives and protocols for the discovery and treatment of tribal resources. As such, impacts to cultural and tribal cultural resources would be greater than the 2045 General Plan Update, but impacts to cultural resources and tribal cultural resources would remain less than significant with mitigation. e. Hydrology and Water Quality
Under the Greater Annexation Alternative, greater development and a larger geographic footprint would introduce more impervious surfaces and infrastructure needs, contributing to greater impacts on hydrology and water quality. As a result, impacts to hydrology and water quality would increase as new development would occur within previously undeveloped areas. Similar to the 2045 General Plan Update, the Greater Annexation Alternative would result in development of open space and agricultural lands east of the City. However, under this alternative, a larger annexation area would be included, which would also increase the amount of new impervious surfaces in greenfield areas and increase potential impacts on undeveloped drainage systems and natural waterways. Similar to the 2045 General Plan Update, the larger Annexation Alternative would be required to adhere to existing NPDES permits and municipal code requirements. Additionally, the Greater Annexation Alternative would also implement policies that aim to protect groundwater supplies, groundwater recharge, and reduce impacts due to the release of pollutants from inundation. Under this alternative, as under the 2045 General Plan Update, stormwater improvements would include the extension of new drainage infrastructure systems into the larger annexation area. However, because the annexation area would be larger under this alternative, new drainage infrastructure systems would need to be extended into a larger area. New development under the Greater Annexation Alternative would still be required to comply with all federal, State, and local regulations to minimize water quality impacts and would not conflict with the Basin Plan.
Therefore, impacts related to hydrology and water quality would be greater than those of the 2045 General Plan Update but would remain less than significant. f. Noise
The Greater Annexation Alternative would result in greater noise impacts due to increased construction activity and traffic generation in areas not previously developed. As such, some new development would occur in locations further from existing sensitive receptors. Construction- related noise would have a somewhat lower impact on residences, schools, or care facilities located near development within the larger annexation area. However, this alternative would still introduce increased daytime noise levels related to construction noise in close proximity to sensitive receptors.
The Greater Annexation Alternative would implement policies aimed at reducing construction and operational noise, as well as groundborne vibration. Development facilitated by the Greater Annexation Alternative would be expected to result in similar stationary noise and groundborne Alternatives
Final Environmental Impact Report 6-13
vibration levels as the 2045 General Plan Update, albeit within a larger footprint. Under this alternative, Mitigation Measures NOI-1(a) and NOI-1(b) would still be required, setting conditions of approval for all development within 500 feet of a sensitive receptor and implementing roadway vehicle noise reduction measures.
The expanded footprint under this alternative may increase traffic noise along roadways with previously minimal traffic noise, thereby increasing ambient noise levels along affected roadways.
However, as details from individual development facilitated by the plan are unknown at this time, there is no feasible mitigation that would avoid or fully mitigate the increase in construction and traffic noise. As a result, potential construction noise impacts and operational traffic noise impacts would remain significant and unavoidable, similar to the 2045 General Plan Update. As under the 2045 General Plan Update, future development facilitated by the Greater Annexation Alternative would involve construction activity that could intermittently generate groundborne vibration affecting nearby properties. Because project-level details are not currently available for future individual development facilitated by the Greater Annexation Alternative, it is not possible to determine which projects may use pile driving or vibratory rollers and their exact vibration levels, locations, or time periods for construction of such projects. As a result, construction vibration levels may exceed the FTA’s vibration levels for preventing architectural building damage. Similar to the 2045 General Plan Update, the Greater Annexation Alternative would require Mitigation Measure NOI-2 to reduce construction vibration impacts to a less than significant level. Therefore, overall noise impacts would be similar to those of the 2045 General Plan Update but would remain significant and unavoidable.
g. Transportation and Traffic
The higher buildout potential and more dispersed development pattern of the Greater Annexation Alternative would generate additional vehicle trips and increase roadway congestion relative to the 2045 General Plan Update. As such, under this alternative, the use of active transportation and transit may decrease as residents would be more dependent on private vehicles. The Greater Annexation Alternative development pattern would increase average trip lengths and require construction of new transit and active transportation infrastructure. As VMT and dependency on private vehicles would increase under the Greater Annexation Alternative, this alternative may conflict with the Connected 2050 RTP/SCS, the Santa Maria Active Transportation Plan, and other applicable transportation plans or policies.
Development facilitated by the Greater Annexation Alternative would be required to comply with State and City requirements related to transportation design safety and emergency access. As the Greater Annexation Alternative would increase the development footprint, per capita VMT compared to the 2045 General Plan Update may also increase, such that the City as a whole would not meet the 17 percent VMT reduction threshold required by SBCAG. Therefore, transportation impacts of the Greater Annexation Alternative would be greater than the 2045 General Plan Update and impacts would remain significant and unavoidable.
h. Utilities and Service Systems
Serving an expanded urban area and a larger population under the Greater Annexation Alternative would increase demand on utility infrastructure and require new extensions, resulting in greater impacts to service systems. New development under this alternative would result in increased demand for water supply, wastewater treatment, solid waste disposal, and other utility services.
Increased demands to previously undeveloped areas and requirements to expand utility provider City of Santa Maria
2045 General Plan Update

service areas would also generate a need for new infrastructure extensions. Existing facilities may also still require upgrades or capacity expansions. Similar to the 2045 General Plan Update, the Greater Annexation Alternative would be subject to applicable state and local requirements and implement policies to ensure adequate public services. Therefore, while impacts would be greater than those of the 2045 General Plan Update, impacts would remain less than significant.
6.5 Environmentally Superior Alternative
CEQA requires the identification of an Environmentally Superior Alternative among the alternatives considered. When the No Project Alternative is determined to be environmentally superior, CEQA also requires identification of the Environmentally Superior Alternative among the development options. Table 6-1 indicates whether each alternative’s environmental impact is greater than, less than, or similar to that of the 2045 General Plan Update for each of the issue areas studied in addition to the overall impact finding (Less than Significant, Significant and Unavoidable, etc.). Based on the alternatives evaluation in Section 6.2 through Section 6.4, Alternative 2, Infill Only Alternative would be the Environmentally Superior Alternative.
Unlike the Greater Annexation Alternative, the Infill Only Alternative would concentrate development in already developed areas of the city by increasing densities and redevelopment. As a result, the Infill Only Alternative would have reduced impacts on agricultural lands, as this alternative would not include the annexation area, thus removing the potential for development to convert agricultural lands outside of the City limits. The Infill Only Alternative would also result in reduced impacts to air quality and GHG emissions, as infill development would encourage the use of active transportation and transit uses due to the proximity of services to residential development.
Additionally, compared to the Greater Annexation Alternative, the Infill Only Alternative would have reduced impacts on biological and cultural resources due to the concentration of development within previously disturbed areas that have low potential for biological resources and low potential to uncover archaeological resources. The Infill Only Alternative would have reduced per capita VMT, as development within the infill areas would reduce buildout potential to a wider area, which would reduce mobile emissions in comparison to the Greater Annexation Alternative. Due to the reduced buildout potential and reduced buildout area, impacts related to hydrology and water quality would also be reduced compared to the Greater Annexation Alternative.
Although the Infill Only Alternative would be the Environmentally Superior Alternative, this alternative would not fulfill the primary objectives of the 2045 General Plan Update, including the provision of housing quality and various housing choices or improving opportunities for connected growth. Further, the Infill Only Alternative would not enhance new and existing neighborhoods such that each neighborhood would be a Complete Neighborhood or provide innovative housing and may result in the City failing to meeting its RHNA obligations in accordance with State law as it would significantly reduce the affordable housing options and limit new housing to infill only and redevelopment.

Attachment 1 – Plan Description
February 17, 2025
Attachment 1 - Plan Description
The plan analyzed in this Environmental Impact Report (EIR) is the City of Santa Maria (City) 2045 General Plan Update, hereafter referred to as the “plan.” This section of the EIR describes the key characteristics of the plan, including the plan proponent/lead agency, the geographic extent of the plan, plan objectives, required approvals, and the development forecasted by the plan.
Plan Purpose
The plan is an update to the City’s current General Plan, which includes the following chapters: Land Use Element, Circulation Element, Safety Element, Health and Environmental Justice Element, Conservation and Open Space Element, Noise Element, Public Facilities and Services Element, Recreation and Parks Element, and Economic Development Element. The plan establishes the City’s vision for future development through the horizon year of 2045. The plan will serve as the City’s primary guide for future land use and development decisions in a way that meets the community needs and priorities while serving as a key tool for influencing and improving the quality of life for residents and businesses. As such, it serves as the “blueprint” for future development and conservation of a community. The 2045 General Plan Update will help the City plan for important community issues, such as community growth; housing, mobility, and infrastructure needs; climate change; and environmental protection. It will also set the stage for future social, physical, and economic development of the city.
Plan Proponent/Lead Agency
The City of Santa Maria is both the plan proponent and the lead agency for the proposed plan. The City’s Community Development Department (located at 110 South Pine Street, Suite 101, Santa Maria, California 93458) prepared this EIR with the assistance of Rincon Consultants, Inc. and Raimi + Associates.
Plan Area Location and Environmental Setting
Regional Location
The City of Santa Maria is located in northern Santa Barbara County, surrounded by the hills of the Santa Maria River Valley (see Figure 1). The General Plan area involves all land within the Santa Maria Sphere of Influence1 (SOI) and includes the annexation of areas east of the city limits (see Figure 2). The City of Santa Maria is generally bound by the Santa Maria River to the north, agricultural lands to the east and west, and the unincorporated town of Orcutt to the south.
1 The term “sphere of influence” applies to the area designated by the Santa Barbara Local Agency Formation Commission (LAFCO) as the probable, future physical boundary or service area of the city. Overall, planning decisions made for the city are assumed to have a bearing on growth and development in these unincorporated adjacent areas. Areas not included as part of the annexation for the 2045 General Plan will continue to be deferred to the County land use designations and regulations in the SOI. Any development or change that happens in the SOI during the lifetime of the General Plan will occur under the jurisdiction of the County. Therefore, this EIR does not evaluate impacts resulting from future growth within the SOI, outside of the proposed annexation, as part of the proposed plan.
However, where relevant, this EIR does evaluate potential impacts resulting from future growth within the city limits to lands within the SOI. The SOI is also included in the cumulative setting for this EIR.

Draft Environmental Impact Report 4
U.S. Highway 101 (U.S. 101) forms the eastern edge of the city. A linear portion of Santa Maria is also located to the west of U.S. 101. This portion of the city extends south from Vineyard Trail Road then extends east along an internal farm road. Santa Maria is located approximately 25 miles south of San Luis Obispo, 50 miles northwest of Santa Barbara, 250 miles south of San Francisco and 170 miles north of Los Angeles.
Principal regional transportation facilities serving Santa Maria are U.S. 101, State Route 135 (SR 135), State Route 166 (SR 166), and the Santa Maria Valley Airport. Regional transit is provided by Clean Air Express and the San Luis Obispo Regional Transit Authority. Regional rail is provided by Amtrak.
Local Setting
The City of Santa Maria is characterized as a suburban residential community. The plan area covers approximately 17,200 acres within the city limits and approximately 4,500 acres within the SOI (City of Santa Maria 2020). Approximately 27 percent of land within Santa Maria is occupied with residential uses, primarily consisting of single-family residences (22 percent). Agricultural uses occupy 14 percent of the city, airport uses occupy 11 percent, public and institutional uses occupy 8 percent, and commercial uses occupy 7 percent. Approximately 19 percent of the city is comprised of vacant land. Residential land uses are distributed throughout the city. Non-residential land uses, including industrial and commercial, commonly line major corridors in Santa Maria, including Broadway, Main Street, and Betteravia Road. Agricultural and vacant uses are located at the periphery of the city. The city is underlain by the Santa Maria River Valley Groundwater Subbasin.
The local climate in Santa Maria is identified as a Mediterranean climate characterized by warm, dry summers and cool, moist winters.
Existing Plan Area Characteristics
The 2045 Santa Maria General Plan area covers approximately 17,200 acres, which includes 12,700 acres within the city limits and 4,500 acres within the Sphere of Influence (SOI). Approximately 110,608 people live within the General Plan area as of January 2024, resulting in population density of approximately 640 people per square mile. There are 34,412 residential units within the General Plan area as of 2024 (California Department of Finance 2024).
The annexation area evaluated in the plan (discussed in detail in Section Error! Reference source n ot found.) covers 985 acres east of the City of Santa Maria’s limits.
Regulatory Setting
State law (Government Code Sections 65300 through 65303.4) requires each municipality to adopt and periodically update its General Plan, and requires that a General Plan include the following mandatory subject areas, or “elements”: Land Use, Circulation, Housing, Open Space, Conservation, Noise, Safety, and Environmental Justice. Municipalities may also prepare optional elements that can be organized or combined at the municipality’s discretion.
The 2045 General Plan has been organized into the following elements: Land Use; Circulation; Safety, Health and Environmental Justice; Conservation and Open Space; Noise; Public Facilities and Services; Recreation and Parks Element; and Economic Development.2 Together, these elements

cover all topics required to be included in a General Plan under State law. The City of Santa Maria City Council adopted the 6th Cycle Housing Element on December 5, 2023. The 2045 General Plan may require additional updates to the adopted Housing Element, although such updates are anticipated to be for consistency with the 2045 General Plan.
Under State law a property’s zoning is required to be consistent with its General Plan land use designation (Government Code Section 65860). Section 65860(c) of the Government Code requires that when a General Plan is amended or updated in a way that makes the Zoning Ordinance inconsistent with the General Plan, “the zoning ordinance shall be amended within a reasonable time so that it is consistent with the general plan as amended.” Plan Objectives
The 2045 General Plan will serve as a long-term framework for future growth and development, represents the community’s view of its future, and contains the goals and policies upon with the City Council, Planning Commission, and the entire community will base land use and resource decisions. The 2045 General Plan will provide a contemporary plan that will guide Santa Maria though the next 20 years. The primary objective of this plan is to update the existing Santa Maria General Plan in order for it to be compliant with State law.
The 2045 General Plan would implement the following vision to guide development.
Vision. Santa Maria in 2045 is a community where families can establish and maintain multi- generational roots. It is close-knit, culturally diverse, and economically inclusive. This is possible, in part, because Santa Maria offers affordable, safe, attractive, and healthy homes and neighborhoods for all residents. This is also possible because of the availability of high-quality education, jobs, and economic opportunity. Building from a strong foundation in the agricultural, retail, healthcare, and business services industries, Santa Maria has continued to diversify by expanding the training and skills of residents and by adapting to new technologies and broader economic trends. People are proud of their history and heritage. This is reflected in the diverse, well-preserved historical resources and the attractive, inviting streets and public gathering places. Museums, art venues, a strong civic sector, and the many welcoming community events and celebrations are all evidence of a vibrant local culture. Residents have convenient access on foot and by car, bus, and bicycle to jobs, schools, community amenities like parks and sports fields, and the region’s natural environment.
Public services are reliable, inclusive, and efficient, and the community is well-served by equitable, modern, and sustainable infrastructure, facilities, and utilities.
The City identifies the following 11 guiding principles, which also serve as the proposed plan objectives for the purposes of complying with CEQA.
▪ Agricultural Identity. Continue to support the agricultural industry and its workforce. Balance the protection of prime agricultural land with the development necessary to support continued population growth and the diversification of the local economy. ▪ Culture, History, and Art. Celebrate and share Santa Maria’s multicultural heritage and contemporary diversity. Preserve historic resources, foster the arts, maintain a strong sense of community through cultural festivals, and invite visitors to enjoy the richness of local expression and resources.
▪ Community Design. Create public spaces that reflect the community identity, foster civic pride, and invite community members to gather, both informally and for events. Design streets, buildings, and landscaping that reflect the community’s history, culture, and natural Attachment 1 - Plan Description
Draft Environmental Impact Report 6
environment. Use lighting, street trees, benches, and other amenities to make sidewalks and public spaces safe and welcoming, with a focus on the Downtown and along the Main and Broadway corridors.
▪ Community Health. Grow and expand physical and mental healthcare services to meet the needs of all residents. Improve community health by addressing the environmental justice priorities of disadvantaged communities, including seniors, low-income households, linguistically isolated families, the homeless, and youth, who comprise 35 percent of residents.
Minimize residents’ potential for exposure to noise, pesticides, and industrial pollution. Foster healthy lifestyles by expanding safe and attractive options for physical activity and by expanding healthy food access.
▪ Natural Environment and Resilience. Conserve water resources in the city and support efforts to maintain the Santa Maria River. Expand opportunities to enjoy the area’s natural resources and the region’s beauty. Safeguard the community from natural hazards, including those exacerbated by climate change.
▪ Housing Quality and Choice. Develop a high-quality and diverse housing supply at all levels of affordability that preserves Santa Maria as a place where families can establish roots and today’s youth can afford to stay. Balance the growth of housing and the economy so that people can live and work in Santa Maria. As new housing types are introduced, (e.g., accessory dwelling units (ADUs)), adapt parking, transportation, and other community features. Develop workforce housing solutions that provide safe, healthy, and comfortable homes for workers and their families.
▪ Resilient Economy. Cultivate a diverse and resilient economy in which local businesses and families thrive and job growth keeps apace with housing development. Grow the existing economic base in agriculture, retail, healthcare, and business services, and expand into new industries. Ensure access to high quality education that is aligned with local industries and entrepreneurship.
▪ Connected Growth. To accommodate projected population, housing, and jobs growth, focus on improvements to existing neighborhoods along with infill and vacant site development. Expand beyond current city limits when needed, weighing the short and long term environmental, economic, infrastructure, public service, and fiscal trade-offs. Establish strong cultural, design, and physical connections between newly developed areas and the rest of Santa Maria. ▪ Transportation Innovations. Develop a balanced, equitable, affordable, and reliable transportation network where pedestrians, cyclists, trucks, cars, rail, and transit can safely and efficiently navigate to destinations within Santa Maria. Focus on maintaining existing roadways, expanding walking and biking options, and reducing congestion and maintenance costs.
Transform corridors and streets from points of conflict among people, cyclists, cars, and trucks into places that bring neighborhoods and families together. Prepare for and expand regional connections with enhanced bus, rail, and air service. Prepare for technological advances like autonomous vehicles and remote work, and take advantage of opportunities and incentives to reduce vehicle miles traveled (VMT) and greenhouse gas (GHG) emissions. ▪ Infrastructure, Utilities, Facilities, and Services. Provide residents and businesses with equitable access to affordable, reliable, and sustainable infrastructure and utilities, including water, wastewater, flood control, gas, phone, cable, and broadband internet. Deliver high-quality services and facilities for all community members, including expedient emergency response, accessible health care, high-quality education and career training, and convenient and equitable access to well-maintained parks and recreational facilities.
Attachment 1 - Plan Description
Draft Environmental Impact Report 7
▪ Governance and Engagement. Continue to conduct and increase meaningful and inclusive civic engagement that empowers a diversity of perspectives in public decision-making. Provide residents and businesses with high-quality, equitable, and accessible customer service, including City communications and events in multiple languages and interpretation services. Partner with community organizations and institutions to build trust and increase participation, including among youth, who will be the City leaders in 2045.
Plan Characteristics
2045 General Plan Update Organization
The elements included in the 2045 General Plan are further described in this section. ▪ Conservation and Open Space Element. This element outlines the development, management, and preservation of natural, tribal, cultural, and historic resources within the plan area. Goals, policies, and actions within this element address climate change adaptation and resilience in relation to natural resources, greenhouse gas emissions reduction, urban forestry, and the use of open space for the conservation of natural, cultural, and other resources as well as for hazard mitigation.
▪ Safety Element. This element addresses natural and manmade safety hazards in Santa Maria, including geologic and seismic hazards, fire hazards, flooding, hazardous materials, and emergency response and establishes policies and actions to mitigate hazard impacts to people and property. The Safety Element also evaluates evacuation capacity under a range of hazard scenarios, identifies single-access neighborhoods, and establishes policies and actions to enhance evacuation capacity throughout the city, consistent with Assembly Bill (AB) 747 and Senate Bill (SB) 99. In accordance with SB 379, this element also includes a climate change vulnerability assessment and measures to address climate vulnerabilities and hazard mitigation and emergency response.
▪ Land Use. This element designates the placement and distribution of future development to facilitate orderly growth within the city. This element establishes future land use patterns and specifies appropriate residential density and development intensity. Goals and policies serve as a guide for decision makers to direct the development of the city. Additionally, this element provides an overall design framework for the city with the goal of preserving community character and highlighting community gateways and views. ▪ Circulation. This element provides a framework for the City’s multimodal transportation network, addressing the movement of people and goods in and around Santa Maria, while ensuring the orderly improvement of the circulation system in response to the Land Use Element. This element also establishes policies related to the electrification of vehicles and commercial enterprises promoting Mobility as a Service (MaaS), complete streets (AB 1358) and VMT (SB 743).
▪ Public Facilities and Services Element. This element evaluates existing and future conditions related to the provision and maintenance of public buildings and services, including parks, schools, libraries, police, fire, and water, wastewater, and stormwater infrastructure. This element presents goals, policies, and actions related to public facilities and services in order to sustain existing households and businesses and accommodate future growth in population, employment, and development.
Attachment 1 - Plan Description
Draft Environmental Impact Report 8
▪ Recreation and Parks Element. This element inventories existing park and recreational resources throughout the city and evaluates future conditions and needs related to parks and recreation. Goals, policies, and actions within this element aim to facilitate equitable distribution of resources and investments to meet the recreational needs of all community members.
▪ Economic Development Element. This element includes goals, policies, and actions related to the retention and expansion of existing business sectors, as well as diversifying the economy to develop new kinds of businesses in Santa Maria.
▪ Noise Element. This element identifies and evaluates sources of noise and groundborne vibration and aims to minimize excessive noise exposure and noise conflicts. This element would be consistent with the Santa Maria Public Airport Master Plan and include new noise contours. ▪ Health and Environmental Justice Element. This element identifies disadvantaged communities within the city and includes goals, policies, and actions to reduce pollution exposure, promote access to food, public facilities, and safe housing, and strengthen civic engagement in City planning and decision making.
The City recently updated its Housing Element, which was adopted on December 5, 2023. The Housing Element provides the City’s action plan for meeting the City’s 6th Cycle Regional Housing Needs Allocation (RHNA) of 5,418 dwelling units for the 6th Cycle Housing Element (2023 to 2031).
The Housing Element has undergone separate CEQA review and for that reason is not part of the plan being evaluated in this EIR. The Housing Element and Initial Study – Mitigated Negative Declaration were adopted on December 5, 2023.
Land Use Designations
The current Santa Maria General Plan Land Use Element establishes 30 separate land use designations to provide a mixture of land uses for the City. The existing City of Santa Maria Land Use Designations Map is shown in Figure 3.
The plan would change some of the land use designations; including planned land use changes that resolve inconsistencies between existing uses and the General Plan land use designations. Land use conflicts primarily consist of industrial, heavy commercial, agricultural, and airport uses in proximity to residential uses. In addition, the plan includes the following land use designation changes:
▪ Revise the High Density Residential (HDR) land use designation to increase the maximum allowed density from 22 dwelling units/acre to 30 dwelling units/acre. ▪ Eliminate the Medium Density Residential-10 (MDR-10) land use designation and reassign all parcels currently designated MDR-10 to MDR-12, which would have an allowed density of 12 dwelling units/acre.
▪ Add two new land use designations, Downtown Specific Plan (SP) and Planned Annexation (PA).
Land use changes for the proposed annexation areas east of the city limits (the planned annexation areas are discussed in detail in the Annexation subsection that follows. Figure 4 shows the changes in land use designations compared to the current General Plan. Proposed changes from the existing General Plan land use pattern include the following:
▪ A parcel along North Broadway from Low Density Residential and Community Commercial to Community Facilities (CF);
▪ Parcels along Main Street from Community Commercial to Main Mixed Use (MMU); Attachment 1 - Plan Description

Attachment 1 - Plan Description
Draft Environmental Impact Report 11
▪ Parcels along Broadway from Community Commercial to Broadway Mixed Use (BMU); and ▪ Allow Low Density Residential in Area 9 along A Stret in the western portion of the city.
Changes in land use designations within the General Plan would also necessitate revisions to the following Specific Plans:
▪ Amend the Entrada Specific Plan to reflect the new Broadway and Main Mixed Use land use designations.
▪ Amend the Area 9 Specific Plan to allow low density residential uses along A Street, consistent with the LMDR-8 designation.
Annexation
The 2045 General Plan would include the annexation of areas east of the city limits and SOI. There are three separate areas (shown in Figure 5) that would be included as part of the proposed annexation (“annexation area”) that would total 985 acres.
The first area proposed for annexation is generally bound by Panther Drive to the west, E. Main Street to the south, and the city limits to the north and east. The second area proposed for annexation is generally bound by S. Suey Road to the west, E. Main Street to the north, E. Jones Street to the south, and Rosemary Road to the east. The third area proposed for annexation is generally bound by E. Jones Street to the north, U.S. 101 to the west, Vineyard Trail Road to the south, and Rosemary Road to the east. Much of the annexation area is vacant or agricultural land.
Existing zoning and land use designations within the annexation area are determined by the County of Santa Barbara and consist primarily of agricultural land use designations (Agriculture II with a minimum lot size of 100 acres [AG-II-100] and Agriculture II with a minimum lot size of 40 acres [AG- II-40]). Land use changes for the annexation area would include the establishment of a new land use designation, Planned Annexation, which would allow for a mix of commercial, residential, industrial, and public land uses in annexed land outside of current city limits.
Noise Contour Revisions
The City of Santa Maria noise characteristics are described within the 2045 General Plan Noise Element including descriptions of common sources of noise as well as goals and policies to lessen noise for sensitive land uses (e.g., residences, schools, medical facilities). As required pursuant to the Governor’s Office of Planning and Research (OPR) Guidelines, the Noise Element also includes a map of noise contours as depicted via lines that represent equal levels of noise exposure across the city. Noise contours information informs planning decisions, including siting of potential future sensitive land uses.
Proposed 2045 General Plan Buildout
For reasonable analysis purposes in this EIR, the City assumes maximum 2045 General Plan buildout (of both residential and non-residential uses) within the city would occur by 2045. Maximum buildout of the General Plan is assumed to be a locally appropriate projection of development within the plan area based on updated land use designations and the proposed annexation rather than development of every parcel within the city. While complete buildout is not likely to occur by 2045, the maximum buildout assumption represents the most conservative approach to evaluating the plans potential environmental effects and satisfying the requirements of the CEQA Guidelines.

For the purposes of this EIR, “General Plan Area” would refer to the City of Santa Maria, the proposed annexation area, and the Sphere of Influence.
Table 1 indicates the net change from 2022 conditions in Santa Maria to maximum buildout of the plan by 2045.

Residential Units 28,200 units 44,340 units 16,140 units Jobs 43,050 jobs 66,800 jobs 23,750 jobs
The 2045 General Plan would add 985 acres of land to the city limits and would provide the framework for development of up to 16,140 net new3 primary and accessory dwelling residential units, including the development of 1,300 accessory dwelling units (ADUs).
The 2045 General Plan would provide the framework for development of up to 1,504 net new non- residential acres, with the following composition (numbers in parentheses indicate a reduction in acreage):
▪ (463) acres of commercial uses
▪ 452 acres of mixed uses
▪ 7 acres of Industrial/airport uses
▪ 33 acres of public and open space
▪ 1,012 acres of planned future development (specific plan and planned annexation areas) Approximately 32 percent of the city remains undeveloped. The undeveloped areas of the city are classified as vacant (19 percent) and agricultural (13 percent). The existing General Plan indicates that 43 percent of the land is classified Open Space, and the remaining 32 percent is classified as industrial. Many of the vacant parcels within the city, clustered between Battles Road, Betteravia Road, and U.S. 101 are either already slated for development or are located within a Specific Plan.
Specific land use designations proposed for the 2045 General Plan area are designed to ensure consistency with the updated Housing Element and existing land uses, such as industrial, heavy commercial, or agricultural. These land use changes would allow for increased residential density along Main Street and Broadway, as well as on opportunity sites with a high potential for redevelopment. Areas of the city with the most potential for change are concentrated in Downtown, neighborhoods in the City Core, Main Street and Broadway, Southwest Neighborhoods (northwest, west, and south of the airport), and areas proposed for annexation. The 2045 General Plan serves as the City’s long-term development blueprint through 2045, contains goals and policies guiding land use and infrastructure decisions through 2045, and brings the General Plan up to date in response to latest State and regional plans and regulations related to climate-related hazards,4 emergency evacuation routes and access, water supply, and mobility.

Intended Use of this EIR
This EIR provides a programmatic environmental review of implementing the City’s 2045 General Plan Update. Subsequent activities falling under the City’s 2045 General Plan Update will utilize this EIR to focus the environmental review of these consequent activities and to determine their effects.
If a new project is proposed that is not anticipated by the 2045 General Plan Update, or that may result in project-level environmental effects not addressed in this program-level EIR, the future project would be evaluated as required under CEQA. This EIR is not intended to prohibit consideration of future projects or CEQA analysis of future projects.
Plan Implementation
Following adoption of the 2045 General Plan Update by the City Council, all subsequent activities and development within the City would be guided by the goals and policies in the 2045 General Plan Update. Therefore, the 2045 General Plan provides specific policy guidance for implementation of plan concepts. The City would also need to coordinate with Santa Barbara County, the Santa Barbara Local Agency Formation Commission (LAFCO), and other public agencies to implement policies that affect their respective jurisdictions, or would affect the region. Implementing these policies in accordance with new development (residential, commercial, or industrial) would be subject to the City’s established review and approval processes, with final review and approval by the appropriate departmental staff, as well as the appointed and elected officials. The principal responsibilities that City officials and staff have for plan implementation are briefly summarized below:
▪ Updating the City of Santa Maria Zoning Ordinance to achieve consistency with the adopted General Plan Update.
▪ Rezoning properties, as dictated by future development proposals. ▪ Approval of tentative maps, variances, planned development and conditional use permits, and other land use permits and entitlements.
▪ Approval of development agreements and issuance of related permits and approvals consistent with the 2045 General Plan Update.
▪ Analyzing and planning for public infrastructure such as roadway improvements, other capital improvements, and natural/capital resource preservation and/or restoration. ▪ Conducting or considering further focused planning studies, as appropriate to future development in the city.
Required Approvals
With recommendations from the City’s Planning Commission, the Santa Maria City Council would need to take the following discretionary actions in conjunction with the plan:
▪ Certification of the Final EIR and adoption of required findings, including required findings under CEQA Guidelines Sections 15090, 15091, and 15093.
▪ Santa Barbara County LAFCO must approve the City’s annexation application, which would include certification of this Environmental Impact Report. ▪ Approval and adoption of the 2045 General Plan Update.

DANA EADY, PLANNING AND DIVISION MANGER
COMMUNITY DEVELOPMENT DEPARTMENT
110 SOUTH PINE STREET, SUITE 101
SANTA MARIA, CA 93458
Dear Dana Eady:
NOTICE OF PREPARATION OF AN ENVIRONMENTAL IMPACT REPORT FOR THE SANTA MARIA GENERAL PLAN UPDATE PROJECT, SCH# 2025020584
The Department of Conservation’s (Department) Division of Land Resource Protection (Division) has reviewed the Notice of Preparation of an Environmental Impact Report for the Santa Maria General Plan Update Project (Project).
The Division monitors and maps farmland conversion on a statewide basis, provides technical assistance regarding the Williamson Act, and administers various agricultural land conservation programs. Public Resources Code, section 614, subdivision (b) authorizes the Department to provide soil conservation advisory services to local governments, including review of CEQA documents.
Protection of the state’s agricultural land resources is part of the Department’s mission and central to many of its programs. The CEQA process gives the Department an opportunity to acknowledge the value of the resource, identify areas of Department interest, and offer information on how to assess potential impacts or mitigation opportunities.
The Department respects local decision-making by informing the CEQA process, and is not taking a position or providing legal or policy interpretation.
We offer the following comments for consideration with respect to the project’s potential impacts on agricultural land and resources within the Department’s purview.
PROJECT ATTRIBUTES
The Project proposes to update the City’s current General Plan, which includes the following chapters: Land Use Element, Circulation Element, Safety Element, Health and Environmental Justice Element, Conservation and Open Space Element, Noise Element, Public Facilities and Services Element, Recreation and Parks Element, and Economic Development Element. The plan establishes the City’s vision for future development through the horizon year of 2045. The plan will serve as the City’s primary guide for State of California Natural R esources Agency | D epartment of Conservation 7 15 P Street, MS 1904, Sacramento, CA 95 814
conservation.ca.gov | T : (916) 324-0850
future land use and development decisions in a way that meets the community needs and priorities while serving as a key tool for influencing and improving the quality of life for residents and businesses. The Project site contains Prime Farmland, Farmland of Statewide Importance, and Unique Farmland as designated by DOC’s Farmland Mapping and Monitoring Program, and a portion of the project site is subject to a Williamson Act contract.
PROJECT CONSIDERATIONS
The conversion of agricultural land represents a permanent reduction and impact to California’s agricultural land resources. The Department generally advises discussion of the following in any environmental review for the loss or conversion of agricultural land:
• Type, amount, and location of farmland conversion resulting directly and indirectly from implementation of the proposed project. • Impacts on any current and future agricultural operations in the vicinity; e.g., land-use conflicts, increases in land values and taxes, loss of agricultural support infrastructure such as processing facilities, etc.
• Incremental impacts leading to cumulative impacts on agricultural land. This would include impacts from the proposed project, as well as impacts from past, current, and likely future projects.
• Implementation of any City or County Agricultural Mitigation Plans, Programs, or Policies.
• Proposed mitigation measures for impacted agricultural lands within the proposed project area.
• The project’s compatibility with lands within an agricultural preserve and/or enrolled in a Williamson Act contract.
WILLIAMSON ACT
Where, as here, the project site is located on land subject to a Williamson Act contract, the Department advises that the environmental review discuss the compatibility of the project with the contract and local Williamson Act program requirements.
MITIGATING AGRICULTURAL LAND LOSS OR CONVERSION
Consistent with CEQA Guidelines, the Department advises that the environmental review address mitigation for the loss or conversion of agricultural land. An agricultural conservation easement is one potential method for mitigating loss or conversion of agricultural land. (See Cal. Code Regs., tit. 14, § 15370 [mitigation includes “compensating for the impact by replacing or providing substitute resources or environments, including through permanent protection of such resources in the form of conservation easements.”]; see also King and Gardiner Farms, LLC v. County of Kern (2020) 45 Cal.App.5th 814.)
Mitigation through agricultural conservation easements can take at least two forms: the outright purchase of easements or the donation of mitigation fees to a local, regional, or statewide organization or agency whose purpose includes the acquisition and stewardship of agricultural easements. The conversion of agricultural land may be viewed as an impact of at least regional significance. Hence, the search for replacement lands may not need to be limited strictly to lands within the project’s surrounding area. A helpful source for regional and statewide agricultural mitigation banks is the California Council of Land Trusts. They provide helpful insight into farmland mitigation policies and implementation strategies, including a guidebook with model policies and a model local ordinance. The guidebook can be found at:
California Council of Land Trusts
Of course, the use of conservation easements is only one form of mitigation, and the Department urges consideration of any other feasible measures necessary to mitigate project impacts.
Thank you for giving us the opportunity to comment on the Notice of Preparation of an Environmental Impact Report for the Santa Maria General Plan Update. Please provide the Department with notices of any future hearing dates as well as any staff reports pertaining to this project. If you have any questions regarding our comments, please contact Farl Grundy, Associate Environmental Planner via email at [email protected].
Sincerely,
Monique Wilber
Conservation Program Support Supervisor
Santa Maria General Plan Update Scoping Meeting
Three attendees joined us in the room for the presentation and subsequent discussion (at the Santa Maria Public Library).
Speakers:
1. Question from one speaker about what is going to happen with Mahoney Ranch. a. Dana Eady response: The GP Update isn’t proposing to change the land use for this property. Notes question about potential future development due to current concerns about CTS/sensitive species on the property.
b. Commenter follow up: Discussion of potential mitigation banking/land swap for addressing impacts and allowing potential development of the property.
2. A second speaker notes the 900+ acres proposed for annexation, and asks if there a phasing plan for development of these annexation areas (e.g, would it be from north to south?).
a. Dana Eady response: Dana said there is not a current plan for the order of future development – likely landowner/developer driven. Discussed the high-level planning process for potential future development of annexation areas, including potential need for future project-specific environmental review. Commenter follow up:
question about whether it would be helpful for the City to have information from landowners about what they may consider bringing forward. Dana Eady/Rincon response: Assumptions for these areas in the EIR will be based on current direction from City Council (CC identified annexation areas being considered, and has expressed a desire for a mix of uses, which informs the EIR PD/projections, and assumptions that will guide the EIR analysis).

6. Climate Risk Detailed Report
6.1. Climate Risk Summary
Cal-Adapt midcentury 2040–2059 average projections for four hazards are reported below for your project location. These are under Representation Concentration Pathway (RCP) 8.5 which assumes GHG emissions will continue to rise strongly through 2050 and then plateau around 2100.
Climate Hazard Result for Project Location Unit
Temperature and Extreme Heat 5.13 annual days of extreme heat Extreme Precipitation 4.70 annual days with precipitation above 20 mm Sea Level Rise — meters of inundation depth
Wildfire 47.0 annual hectares burned
Temperature and Extreme Heat data are for grid cell in which your project are located. The projection is based on the 98th historical percentile of daily maximum/minimum temperatures from observed historical data (32 climate model ensemble from Cal-Adapt, 2040–2059 average under RCP 8.5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.
Extreme Precipitation data are for the grid cell in which your project are located. The threshold of 20 mm is equivalent to about ¾ an inch of rain, which would be light to moderate rainfall if received over a full day or heavy rain if received over a period of 2 to 4 hours. Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.
Sea Level Rise data are for the grid cell in which your project are located. The projections are from Radke et al. (2017), as reported in Cal-Adapt (Radke et al., 2017, CEC-500-2017-008), and consider inundation location and depth for the San Francisco Bay, the Sacramento-San Joaquin River Delta and California coast resulting different increments of sea level rise coupled with extreme storm events. Users may select from four scenarios to view the range in potential inundation depth for the grid cell. The four scenarios are: No rise, 0.5 meter, 1.0 meter, 1.41 meters Wildfire data are for the grid cell in which your project are located. The projections are from UC Davis, as reported in Cal-Adapt (2040–2059 average under RCP 8.5), and consider historical data of climate, vegetation, population density, and large (> 400 ha) fire history. Users may select from four model simulations to view the range in potential wildfire probabilities for the grid cell. The four simulations make different assumptions about expected rainfall and temperature are: Warmer/drier (HadGEM2-ES), Cooler/wetter (CNRM-CM5), Average conditions (CanESM2), Range of different rainfall and temperature possibilities (MIROC5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

6. Climate Risk Detailed Report
6.1. Climate Risk Summary
Cal-Adapt midcentury 2040–2059 average projections for four hazards are reported below for your project location. These are under Representation Concentration Pathway (RCP) 8.5 which assumes GHG emissions will continue to rise strongly through 2050 and then plateau around 2100.
Climate Hazard Result for Project Location Unit
Temperature and Extreme Heat 5.13 annual days of extreme heat Extreme Precipitation 4.70 annual days with precipitation above 20 mm Sea Level Rise — meters of inundation depth
Wildfire 47.0 annual hectares burned
Temperature and Extreme Heat data are for grid cell in which your project are located. The projection is based on the 98th historical percentile of daily maximum/minimum temperatures from observed historical data (32 climate model ensemble from Cal-Adapt, 2040–2059 average under RCP 8.5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.
Extreme Precipitation data are for the grid cell in which your project are located. The threshold of 20 mm is equivalent to about ¾ an inch of rain, which would be light to moderate rainfall if received over a full day or heavy rain if received over a period of 2 to 4 hours. Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.
Sea Level Rise data are for the grid cell in which your project are located. The projections are from Radke et al. (2017), as reported in Cal-Adapt (Radke et al., 2017, CEC-500-2017-008), and consider inundation location and depth for the San Francisco Bay, the Sacramento-San Joaquin River Delta and California coast resulting different increments of sea level rise coupled with extreme storm events. Users may select from four scenarios to view the range in potential inundation depth for the grid cell. The four scenarios are: No rise, 0.5 meter, 1.0 meter, 1.41 meters Wildfire data are for the grid cell in which your project are located. The projections are from UC Davis, as reported in Cal-Adapt (2040–2059 average under RCP 8.5), and consider historical data of climate, vegetation, population density, and large (> 400 ha) fire history. Users may select from four model simulations to view the range in potential wildfire probabilities for the grid cell. The four simulations make different assumptions about expected rainfall and temperature are: Warmer/drier (HadGEM2-ES), Cooler/wetter (CNRM-CM5), Average conditions (CanESM2), Range of different rainfall and temperature possibilities (MIROC5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Subject: Annexation Study
1.0 Introduction
This technical memorandum provides foundational background analysis for the City of Santa Ma
ria's Sphere of Influence (SOI) and Annexation applications. The purpose of this analysis is to support the City in evaluating the capacity of its existing water and wastewater systems to meet current and future needs, including potential annexation areas.
The memorandum is organized as follows:
• Present and Probable Needs
• Capacity Analysis of Sewer and Water Facilities
• Recommended Infrastructure to Support Annexation Area
2.0 Present and Probable Needs
T
his section addresses SOI Section 10.B: “Present and probable needs for sewer and water fa
cilities.” It is divided into two primary parts: one focusing on the present water and sewer system needs and the other summarizes the projected buildout needs.
2.1 Present Needs
T
able 2.1 summarizes the City’s current water system demand. System demand represents the to
tal quantity of water used, encompassing customer consumption, authorized non-customer usage, and distribution losses. This demand is calculated by summing supply data from all sources over a calendar year, covering the years 2020 through 2023, with an average calculated over this period.

2.2 P robable Buildout Needs
Water demand and wastewater flow at buildout was estimated by multiplying the average a
nnual per capita need with the population expected at buildout. The population at buildout was estimated based on the existing and proposed housing units within City limits, proposed housing units in the annexation area, and a persons per household factor of 3.76 sourced from US Census data. Table 2.3 shows the projected housing units and population at buildout.

The water demand at buildout was estimated by combining the projected demand from proposed growth with the existing water demand. The projected demand was determined using the anticipated population growth and a per capita water use factor of 109 gallons per person per day (gpcd) as indicated in the City’s 2020 Urban Water Management Plan (UWMP). This water demand factor was used because the UWMP is the City’s most recently published planning document. Table 2.4 summarizes the projected buildout water demand for the City and the annexation area.

Similar to the water demand projections, sewer flow at buildout was estimated by combining the projected flows from proposed growth with the existing sewer flows. The projected flow was determined based on the anticipated population growth and a per capita flow factor of 66.1 gpcd. This factor was selected as it aligns with the City’s draft Wastewater Treatment Plant Master Plan, currently in development. Table 2.5 summarizes the projected wastewater flow at buildout.

3.1 Water System Capacity
This analysis evaluates the City’s water system capacity in terms of supply, storage, and d
istribution.
3.1.1 S upply Capacity
The supply capacity of the City’s water system was assessed for normal, single dry, and m
ultiple dry year conditions. Available supply under each scenario is based on the City’s 2020 Urban Water Management Plan (UWMP). (Provost & Pritchard Consulting Group, 2021) Tables 3.1, 3.2, and 3.3 present the available supply under each scenario. All scenarios show the City having sufficient supply to meet demand. The City anticipates that annexation will include the transfer of water rights sufficient to reliably offset the increased demand created by the annexation, thereby increasing the City’s available supply.

1 Supply and demand values are in acre-feet.
2 Fifth year demand values have been revised from what is in the UWMP to match those in the first through fourth year scenarios because the UWMP inexplicably shows an increase in demand in the fifth year of a drought.
3.1.2 Storage Capacity
The City’s storage capacity was assessed based on the 2012 UCS. Usable storage volume is a
pproximately 18 MG, distributed across three reservoirs.
Table 3.5 presents current and buildout storage requirements, including operational, fire flow, and emergency storage needs. The operational and emergency storage volumes are calculated as factors of ADD and PHD compared to reliable well capacity. The fire flow storage volume is calculated based on the City’s largest fire flow. (Water Systems Consulting (WSC), Inc, 2015) To meet buildout needs, storage improvements will be required, as indicated in the 2012 UCS.
The 2012 UCS recommended increasing the number of generators in the distribution system from 3 to 5. This analysis found that 5 generators would be sufficient with the addition of the annexed areas. This analysis is summarized in Table 3.6.

2 Assumes a fire flow of 3,000 gpm for 4 hours.
3 Calculated as 2 days of ADD minus existing reliable well capacity. 4 Required volumes at buildout are greater than available storage volume.
3.1.3 Distribution System Capacity
Once an annexation area is determined, the City’s hydraulic model will be used to analyze the s
ystem’s capability to meet this increased demand. The City’s water system is well looped, has average system pressures between 60 and 80 psi, and has a strong background of mains that are 18-inch diameter or greater. These factors indicate that the distribution system is adequately sized to provide maximum day demand + fire flows under existing plus annexation demands.
Minor distribution system improvements may be recommended to meet build-out demands.
3.2 W
astewater System Capacity
The wastewater capacity analysis evaluates both the WWTP and the wastewater collection s
ystem.
3.2.1 W astewater Treatment Plant Capacity
The City’s current WWTP capacity is 8.0 mgd (California Regional Water Quality Control Board, C
entral Coast Region, 2010). Table 3.8 compares the current WWTP capacity to various flow conditions.

City of Santa Maria 7 Santa Maria General Plan Update
The City is currently updating its wastewater treatment plant master plan and has submitted a time schedule compliance plan to the Regional Water Quality Control Board with timelines for upgrading and expanding the existing WWTP to meet more strict discharge requirements and increased flows due to annexation and buildout. Based on this draft master plan, the WWTP will be expanded in two phases. The first phase, expected to be complete in 2032, will increase the WWTP’s capacity to 10 mgd. The second phase, expected to be complete in 2052, will further increase the WWTP’s capacity to 11.5 mgd. Buildout flows, including annexation, are projected at 11.2 mgd, so no additional improvements will be necessary.
3.2.2 W astewater Collection System
The annexation will increase wastewater flows and likely require upgrades to the City’s c
ollection system. The existing collection system experiences some capacity issues, specifically in pipes near the WWTP, which can experience surcharging during high flows. The annexation will require either upsizing the City’s existing trunk lines between the annexation area and the WWTP or the installation of dedicated sewer trunk lines from the annexation area to the WWTP.
Final annexation details will determine specific improvements.
4.0 R
ecommended Infrastructure to Support
Annexation Area
This section addresses requirements outlined in Annex Section 14.B, "Describe the level and r
ange of the proposed sewer and water infrastructure," and Annex Section 14.D, "Indicate any improvements or upgrading of sewer and water facilities that will be required."
4.1 P roposed Infrastructure for Annexation Area
The annexation area will be developed with essential infrastructure, including water distribution s
ystem piping, valves, and other components, as well as wastewater collection system piping, manholes, and related appurtenances. Both water and wastewater systems will be integrated into the City’s existing infrastructure, designed to support reliable service to the annexation area.
4.2 R
equired Improvements of Existing Systems
For the water system, no substantial improvements are anticipated. The current system has a
dequate supply and storage capacity to accommodate the annexation area, and the areas under consideration fall within the City’s existing pressure zone, eliminating the need for additional capacity adjustments.
The wastewater system, however, will likely require the construction of a new sewer trunk line extending approximately 6.5 to 8.5 miles to effectively serve the annexation area. Additionally, if development proceeds rapidly, the City’s WWTP may require upgrades to meet the increased ATTACHMENT 2
