INTRODUCTION

This document is an Addendum to the Airpark Specific Plan Final Mitigated Negative Declaration (MND) (State Clearinghouse Number: 2006121095), which was adopted by the Santa Paula City Council in 2007. The Addendum analyzes the environmental effects of the proposed updates to the Airpark Specific Plan, which involves a 2.69% increase in the building footprints, an increase in the maximum allowable building height, and several other minor changes to the Specific Plan development on the same site considered as part of the adopted Airpark Specific Plan. The Addendum has been prepared in accordance with relevant provisions of the California Environmental Quality Act (CEQA) of 1970 (as amended) and CEQA Guidelines Sections 15162 and 15164.

According to Section 15164 of the CEQA Guidelines, an addendum to a previously adopted Negative Declaration is the appropriate environmental document in instances when "only minor technical changes or additions are necessary" and when the new information does not involve new significant environmental effects beyond those identified in the previous document.

As discussed in detail below, the impacts associated with the updated Airpark Specific Plan are generally within the parameters considered in the Airpark Specific Plan MND. As supported by the analysis below, the proposed development would have no new significant environmental effects beyond those identified in the Airpark Specific Plan MND. Therefore, this Addendum is the appropriate environmental document under CEQA. As discussed below, mitigation measures identified in the Airpark Specific Plan MND would apply to the current proposal.

This Addendum describes the currently proposed (revised) Airpark Specific Plan and compares its impacts to those identified in the 2007 (adopted) Airpark Specific Plan MND.

PROJECT DESCRIPTION/BACKGROUND

Project Site Location The Airpark Specific Plan area encompasses approximately 12.37 acres in the City of Santa Paula (Santa Paula) in Ventura County. Santa Paula is located about 50 miles northwest of Los Angeles and 10 miles northeast of the City of Ventura. Figure 1 shows the location of Santa Paula within the Southern California region.

The Specific Plan area is located in the southern portion of the City, immediately north of the Santa Clara River, immediately east of the Santa Paula Airport, south of Santa Maria and Santa Clara Streets, and west of 12th Street. Figure 2 shows the location of the Specific Plan area. The Specific Plan divides the area into two sub-zones, Airpark-1 and Airpark-2 (see Figure 3).

The Airpark Specific Plan, which was adopted by the Santa Paula City Council in 2007, provides an overall vision for a 12.37-acre plan area to accommodate a combination of light industrial, business and residential uses. The Specific Plan is intended to implement the Guiding Principles of the Comprehensive Land Use Plan and the Santa Paula General Plan.

The Specific Plan is intended to reinforce the planning principles, aeronautical architectural styles, existing airport operations & uses and the heritage and values of the Santa Paula.

As originally adopted, the Airpark Specific Plan was intended to accommodate 37 private airplane hangars/residential condominiums with 2nd floor living space and light industrial and outdoor storage uses. The building footprints totaled 70,270 square feet (sf). The Specific Plan divides the area into two sub-zones, Airpark-1 and Airpark-2. Airpark-1 would accommodate the development of 37 hangar/residential units and Airpark-2 would accommodate the future redevelopment of an existing, in part non-conforming residential/industrial area into light industrial and outdoor storage & parking uses conforming to restrictions governed by FAA regulation within a Protection Zone (RPZ) aka Inner Safety Zone (ISZ.) Specific development plans for the redevelo pment of Airpark-2 are not available. The hangar/residential concept is a live and fly-in development, which would allow residents to live above their private airplane hangar. The 37 units were to be located in a total of thirteen buildings and were to consist of an airplane hangar on the ground floor and a residential dwelling unit on the 2nd floor. The units were to be developed as condominiums.

Current (2017) Proposal

The currently proposed Airpark Specific Plan would also accommodate 37 private airplane hangars/residential/business/light industrial condominiums with 2nd floor living and/or business/light industrial space in Airpark-1 and light industrial and outdoor storage uses restricted by FAA regulations to specific locations within Airpark-2 . The Airpark-1 building footprints would total 72,162 sf, a 2.69% increase from the previous Specific Plan, in order to include new elevator shafts to facilitate Americans with Disabilities Act (ADA) access to upper floors. The upstairs areas within the 37 units would no longer be designed and completed by the applicant, instead they would be offered as shell buildings with firewalls and all other work would be completed by the owner/tenant and their contractors under a separate Oth permit. er changes from the original Specific Plan include:

• An increase in building height from 35 feet to 45 feet per the original Light Industrial zoning;

• Modifications to parking and landscape areas to ensure all parking spaces conform to City standards;

• An addition of an amenity area designated for recreational use; • Classification of phasing for building erection and infrastructure improvement; • Alteration of building colors, rail treatments, and canting of roof for aesthetics; • The addition of an entry exhibit detailing the alteration of the Entry roadway and gate design;

• The addition of an Airpark-2 Uses Exhibit indicating areas of FAA-restricted use; • Modification of the entry driveway to add a pull over lane for postboxes access and USPS & UPS-FEDEX deliveries, as well as a dedicated visitors and delivery lane/gate, plus a Fire Department Turnaround; and

• The addition of an exhibit detailing alleyway signage and unit signage to help with navigation of the project with visitors, delivery drivers and emergency vehicles.

ENVIRONMENTAL IMPACTS OF THE PROPOSED AIRPARK SPECIFIC PLAN

This section addresses each of the environmental issues discussed in the 2007 Airpark Specific Plan Final MND to determine whether or not the current (2017) proposal has the potential to create new significant impacts or a substantial increase in the significance of a significant impact as compared to what was identified in the 2007 Airpark Specific Plan MND.

Aesthetics

Scenic Vistas The Airpark Specific Plan Final MND identifies a less than significant impact related to the alteration of scenic vistas. State Route (SR) 126, which is an eligible scenic highway corridor, located north of the plan area, offers partial views of the plan area. However, the plan area is not identified by the Santa Paula General Plan as an important scenic resource and development under the 2017 and proposed Airpark Specific Plan would be consistent with the current visual character of the area. The proposed Specific Plan would allow a 28 per cent increase in building height (45 feet versus 35 feet), but this change would not substantially alter impacts to scenic vistas of South Mountain. The proposed Specific Plan update would not create any new significant scenic vista impacts nor increase the severity of significant scenic vista impacts beyond those identified in the 2007 Airpark Specific Plan Final MND.

Scenic Resources and Visual Character The Airpark Specific Plan Final MND identifies a less than significant impact related to the alteration of scenic resources and visual character. The plan area is not identified by the Santa Paula General Plan as an important scenic resource and development under the 2007 and proposed Airpark Specific Plan would be consistent with the current visual character of the area. The 2.69% increase in the building footprints, the ten-foot increase in building height, and the alteration of building colors, rail treatments, and canting of roofs associated with the proposed Specific Plan would not create any new significant scenic resources or visual character impacts nor increase the severity of significant scenic resources or visual character impacts beyond those identified in the 2007 Airpark Specific Plan Final MND.

20 of 46 City of Santa Paula Airpark Specific Plan Addendum #2 to the Mitigated Negative Declaration

Light and Glare The Airpark Specific Plan Final MND identifies a less than significant impact related to light and glare. No new or altered lighting is proposed as part of the updated Specific Plan. Therefore, the updated Specific Plan would not result in any new significant light and glare impacts or increase the severity of significant light and glare impacts beyond those identified in the 2007 Airpark Specific Plan Final MND.

Agricultural Resources

The Airpark Specific Plan Final MND identifies no impacts related to agricultural resources. The Specific Plan area does not contain any farmland and no new impacts related to agricultural resources would occur.

The Specific Plan area is located within the South Central Coast Air Basin (the Basin) and within the jurisdiction of the Ventura County Air Pollution Control District (APCD). Air pollution is potentially hazardous to health and can diminish the production and quality of many agricultural crops, reduce visibility, degrade soils materials, and damage vegetation. Human health effects are the key determinant in the establishment of the primary air quality standards. The health and safety effects of air pollutants are described in detail in the APCD Air Quality Management Program (AQMP). The following provides a summary of key pollutants of concern in the South Central Coast Air Basin.

Carbon Monoxide. Carbon monoxide (CO), a colorless, odorless, poisonous gas, is a local pollutant that in high concentrations is found very near the source. Carbon monoxide is a by-product of fuel combustion, but is generally not a concern with typical residential stationary sources (gas water and space heaters, gas dryers) since these are required by law to be properly vented. Automobile traffic is a major source of carbon monoxide with elevated concentrations usually found near areas of high traffic volumes. Carbon monoxide's health effects are related to its affinity for hemoglobin in the blood. At high concentrations, carbon monoxide reduces the amount of oxygen in the blood, causing heart difficulties in people with chronic diseases, reduced lung capacity and impaired mental abilities. Nitrogen Dioxide.

21 of 46 City of Santa Paula Airpark Specific Plan Addendum #2 to the Mitigated Negative Declaration

Nitrogen dioxide (NO2) is a by-product of fuel combustion, with the primary source being motor vehicles and industrial boilers and furnaces. The principal form of nitrogen oxide

produced by combustion is nitric oxide (NO), but NO reacts rapidly to form NO2, creating

the mixture of NO and NO2 commonly called NOX. Nitrogen dioxide is an acute irritant, but at typical atmospheric concentrations, it is only potentially irritating. A relationship between

NO2 and chronic pulmonary fibrosis may exist, and an increase in bronchitis in young children at concentrations below 0.3 parts per million (ppm) may occur. Nitrogen dioxide absorbs blue light and causes a reddish brown cast to the atmosphere and reduced visibility. It

can also contribute to the formation of PM10 and acid rain.

Ozone. Ozone is produced by a photochemical reaction (triggered by sunlight) between nitrogen

oxides (NOX) and reactive organic gases (ROG). Nitrogen oxides are formed during the combustion of fuels, while reactive organic gases are formed during combustion and evaporation of organic solvents. Because ozone requires sunlight to form, concentrations exceeding state and federal standards occur primarily between the months of May and October. Ozone is a pungent, colorless toxic gas with potential health effects on humans including respiratory and eye irritation and possible changes in lung functions. Groups most sensitive to ozone include children, the elderly, people with respiratory disorders, and people who exercise strenuously outdoors.

Suspended Particulates. Particulate matter refers to small, airborne particles that can be inhaled by humans and other animals. The two categories of particulate matter of greatest concern are PM10 and PM2.5. PM10 is

small particulate matter measuring no more than 10 microns in diameter, while PM2.5 is fine particulate matter measuring no more than 2.5 microns in diameter. Suspended particulates are mostly composed of dust particles, nitrates, and sulfates, and are a by-product of fuel combustion and wind erosion of soil and unpaved roads. Suspended particulates are also created in the atmosphere through chemical reactions. The characteristics, sources, and potential

health effects associated with PM10 and PM2.5 can be very different. PM10 generally comes from windblown dust, dust kicked up from mobile sources, and dust created by crushing, grinding, or abrading surfaces during grading operations or other means by which large particles are broken into smaller ones. PM2.5 is generally associated with combustion processes and motor vehicle exhaust, especially from diesel engines. It can also be formed in the atmosphere as a secondary pollutant through chemical reactions.

As the local air quality management agency, the APCD is required to monitor air pollutant levels to ensure that state and federal air quality standards are met and, if they are not met, to develop strategies to meet them. Depending on whether or not the standards are met or exceeded, the Basin is classified as being in "attainment" or "nonattainment." Ventura County was designated as attainment for the federal 1-hour ozone standard as of May 27, 2009. Ventura County is designated under the federal 2008 standard as nonattainment for 8-hour ozone levels

(EPA, 2013) and under the state standards as nonattainment for ozone, PM2.5, and PM10 (APCD, 2014). Thus, the APCD is required to implement strategies to reduce pollutant levels to recognized acceptable standards. The APCD has adopted an AQMP that provides a strategy for the attainment of state and federal air quality standards.

The nearest and most representative (in terms of location and topography) air quality monitoring stations are in El Rio and Piru. The El Rio monitoring station is approximately 8.5 miles southwest of the Specific Plan area. The Piru monitoring station is approximately 14.5 miles northeast of the Specific Plan area. As shown in Table 1, concentrations of ozone and nitrogen dioxide at the El Rio monitoring station did not exceed federal or state standards

during 2011-2013. Concentrations of PM10 at this station exceeded the state standard once in 2011 and once in 2012, but did not exceed the federal standard in any of these years. As shown in Table 2, ozone concentrations at the Piru monitoring station exceeded the state standard once in 2011, but did not exceed the federal standard during the period from 2011-2013. There was no

exceedance of the PM2.5 federal standard from 2011 to 2013.

Accessed June 5, 2014.

Air Quality Policy Consistency According to the APCD Guidelines, to be consistent with the AQMP, a project must conform to the local general plan and must not result in or contribute to an exceedance of the City's projected population growth forecast. The 2007 MND found that the Specific Plan would generate a net increase of 24 residential units, due to the demolition of existing residences on- site, which would generate a net population increase of up to approximately 26 people. This was within the 13,445 person increase projected within the 2007 MND for the City in the Ventura County AQMP. Thus, the Specific Plan was determined to be consistent with the AQMP.

The updates to the Specific Plan would not affect the demolition of the existing residences, or the number of on-site residential/business/light industrial units to be constructed; therefore, it would generate a population increase of up to approximately 26 people. When added to the current population of the City, the additional residents would result in a population of 30,474 (U.S. Census, 2014). This citywide population would remain within the Ventura Council of Governments' 2040 population forecast of 44,650. Thus, the updated Airpark Specific Plan would be consistent with the AQMP and would not create any new significant impacts beyond those identified in the 2007 Airpark Specific Plan Final MND or increase the severity of significant impacts identified in the MND.

Carbon Monoxide Hot Spots A project's localized air quality impact is considered significant if the additional CO emissions resulting from the project create a "hot spot" where the California 1-hour standard of 20.0 ppm or the 8-hour standard of 9.0 ppm is exceeded. This typically occurs at severely congested intersections. The APCD's Air Quality Assessment Guidelines indicate that screening for possible elevated CO levels should be conducted for severely congested intersections experiencing levels of service (LOS) E or F with project traffic.

24 of 46 City of Santa Paula Airpark Specific Plan Addendum #2 to the Mitigated Negative Declaration

The 2007 MND found that Specific Plan buildout would generate an increase in vehicle trips in the area, which would incrementally increase CO concentrations along area roadways. It was determined that levels of service would remain at D or better at all study area intersections. Therefore, CO screening was not necessary and CO "hot spots" were not expected to occur. All of Ventura County was and is in attainment of state and federal CO standards and no violations of CO standards are expected anywhere in the County. The proposed Specific Plan updates include the development of the same number of units included in the 2007 Specific Plan; therefore, it would not create any new significant impacts related to CO concentrations.

Operational Impacts The MND identifies operational air quality impacts as less than significant for the 2007 Specific Plan. The estimated emissions from operation of motor vehicles associated with employee commutes and with delivery vehicles were 4.52 lbs/day of reactive organic gases (ROG) and

2.41 lbs/day of NOx, both of which are below the APCD's 25 pounds per day thresholds.

The proposed Specific Plan updates would entail operation of the same number of units included in the 2007 Specific Plan; therefore, emissions would also be the same. Operational emissions would not exceed APCD thresholds and would not create any new significant impacts beyond those identified in the MND.

Construction Impacts The MND identifies construction-related air quality impacts as significant but mitigable due to the use of heavy equipment to establish final grades, as well as vehicle emissions associated with construction workers commuting to and from the plan area.

The Ventura County APCD's Guidelines for the Preparation of Air Quality Impact Analyses do not establish impact thresholds for construction-related emissions because they are temporary. Although construction impacts are less than significant on a project level, cumulative air quality impacts are of regional concern and standard measures are required for construction projects. Therefore, Mitigation Measure AQ-1, which includes ozone precursor control measures, fugitive dust control measures, and general dust controls, was recommended in the 2007 MND to mitigate cumulative regional impacts associated with construction activities. The proposed Specific Plan updates include an increase of 2.69% for the building footprints, which would have a negligible impact on construction emissions. Therefore, the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND and Mitigation Measure AQ-1 would apply to construction on the plan area.

25 of 46 City of Santa Paula Airpark Specific Plan Addendum #2 to the Mitigated Negative Declaration

Sensitive Receptors As discussed above, development under the 2007 Specific Plan and the proposed updates would increase vehicle trips in the area, which would be expected to slightly increase carbon monoxide (CO) concentrations along area roadways. Because of the currently low CO concentrations in the area and low volumes of existing and plan generated traffic, no exceedances of state or federal CO standards are anticipated. Therefore, sensitive receptors in the area would not be exposed to substantial pollutant concentrations. The proposed Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Objectionable Odors The primary source of odor associated with residential uses (airplane hangar/residential condominium units) is related to refuse storage. Refuse generated by the 2007 Specific Plan and the proposed updates would be typical of residential uses and would consist of organic and inorganic materials. All plan area development would be required to comply with City regulations regarding the storage and handling of refuse and no significant impacts are anticipated. The proposed Specific Plan updates would not create any new significant impacts beyond those identified in the 2007 MND or increase the severity of significant impacts identified in the MND.

Biological Resources

Special Status Wildlife Species The 2007 MND determined that no endangered, rare, candidate, sensitive, or special status species have been identified within the specific plan area, and none were anticipated due to the disturbed nature of the area. The updates to the Specific Plan do not alter the location of the area and the on-site habitat has not been altered since the 2007 MND was adopted; therefore, the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

26 of 46 City of Santa Paula Airpark Specific Plan Addendum #2 to the Mitigated Negative Declaration

Riparian Habitat and Sensitive Natural Communities The Airpark Specific Plan MND did not identify riparian communities, locally designated species, or natural communities within the plan area. However, the applicant proposes to connect two stormwater facility outfalls to the existing onsite drainage outlets in the Airpark- 1 area, which would exacerbate erosion in the area and the Santa Paula River. The updates to the Specific Plan do not affect the drainage proposal or the amount of drainage that would occur; therefore, the updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND and would be subject to Mitigation Measure BIO-1, which requires energy dissipating structures to reduce the potential impacts from increased erosion.

Riparian and Wetland Habitat The Airpark Specific Plan MND found that the plan area was dominated by upland and ruderal vegetation and that no riparian habitat or wetland habitat existed on the plan area. The updates to the Specific Plan do not alter the location of the area and the on-site habitat has not been altered since the 2007 MND was adopted; therefore, the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Wildlife Dispersal and Migration Corridors The Airpark Specific Plan MND determined that due to the surrounding developed land, with the exception of the Santa Clara River to the south, the plan area was highly disturbed and not part of a known significant wildlife migration corridor. The updates to the Specific Plan do not alter the location of the area and the on-site habitat has not been altered since the 2007 MND was adopted; therefore, the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Habitat Conservation and Natural Conservation Community Plans The City's Development Code includes protection for mature trees on public property, or native oak, sycamore and heritage/historic trees on public and private property. The Airpark Specific Plan MND determined that the plan area did not contain any protected trees. It was also determined that the Specific Plan would not conflict with any local biological resource policies or ordinances, and that the plan area is not located within either a Habitat Conservation Plan or a Natural Conservation Community Plan. The updates to the Specific Plan do not alter the location of the area and the on-site habitat has not been altered since the

27 of 46 City of Santa Paula Airpark Specific Plan Addendum #2 to the Mitigated Negative Declaration

2007 MND was adopted; therefore, the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Cultural Resources

Historical Resources Phase 1 (development of Airpark-1) of the proposed Specific Plan, as analyzed in the MND, would not adversely affect any existing structures. Phase 2 could involve demolition of existing residences; however, no structures within Airpark-2 are listed in the National Register of Historic Places or the California Register of Historic Resources. The updates to the Specific Plan do not alter the location of the area and no buildings have been determined to be historic resources since the 2007 MND was adopted; therefore, the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Archaeological Resources and Human Remains The Airpark Specific Plan MND determined that although the plan area has been previously disturbed by development activity, the possibility that undiscovered resources are present on- site exists. Mitigation measures CR-1 and CR-2 would apply to the Specific Plan and be sufficient to reduce impacts to a less than significant level. The updates to the Specific Plan do not alter the location of the area; therefore, the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Paleontological Resources and Geologic Features The Airpark Specific Plan MND found that no paleontological resources or unique geologic features were known to exist in the plan area. The updates to the Specific Plan do not alter the location of the area and no paleontological resources or geologic features have been discovered; therefore, the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Geology and Seismicity

Surface Rupture The Airpark Specific Plan MND found that the plan area is not within an identified Alquist- Priolo Earthquake zone and that no known active or potentially active faults cross the plan area. The updates to the Specific Plan do not alter the location of the plan area and no faults have been discovered; therefore, the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Ground Shaking As discussed in the Airpark Specific Plan MND, the structures built throughout the plan area would need to be constructed to withstand anticipated ground shaking intensity for the area, in accordance with the requirements of the California Building Code. These requirements would apply to the updated Specific Plan and ensure that impacts would be less than significant. The updates to the Specific Plan do not alter the location of the plan area and ground shaking would not be stronger than determined in the MND; therefore, the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Liquefaction The Airpark Specific Plan MND identifies a significant but mitigable impact related to the introduction of new buildings that could be subject to liquefaction hazards. Mitigation Measure GEO-1, which requires implementation of the recommendations of a geotechnical report to be conducted prior to development approval, would reduce the impact to a less than significant level. Implementation of this measure would ensure that the proposed Specific Plan updates would not create any new significant liquefaction impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Landslides, Debris, and Mud Flows The plan area is flat and is not subject to land-sliding, debris flows, or mud flows. The updates to the Specific Plan would not alter the location of the plan area; therefore, the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

29 of 46 City of Santa Paula Airpark Specific Plan Addendum #2 to the Mitigated Negative Declaration

Soil Erosion The Airpark Specific Plan MND identifies a less than significant impact associated with soil erosion due to the sand composition of the plan area. The updates to the Specific Plan would not alter the location of the plan area and the sand composition has not changed. Although the building footprints would be 2.69% larger than the MND assessed, the impacts on erosion would be negligible; therefore, the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Soil Stability The Airpark Specific Plan MND identifies a potentially significant impact related to soil stability and soil settlement through modification of existing on-site topography. The structures in Airpark-1 would be most likely to be negatively affected; however, with implementation of Mitigation Measure GEO-1, the impact would be reduced to a less than significant level. Although the building footprints would be 2.69% larger than the MND assessed, the impacts on soil stability would be negligible; therefore, the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Expansive Soils The Airpark Specific Plan MND determined that the soil type present on the plan area has a low shrink-swell potential and that impacts related to expansive soils would not occur. The updates to the Specific Plan would not alter the location of the plan area; therefore, the same soils are present and the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Septic Systems The plan area is served by the City of Santa Paula municipal sewer system. As discussed in the MND, no impacts to septic systems would occur. The updates to the Specific Plan would not alter the location of the plan area or require the inclusion of any septic systems; therefore, the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Greenhouse Gas (GHG) Emissions

GHG emissions were not assessed as part of the Airpark Specific Plan MND, as the impact was not considered under CEQA at the time. As the current Specific Plan is being developed, GHG impacts would be considered significant if plan-generated GHGs exceed suggested thresholds. However, neither APCD nor the City of Santa Paula have adopted GHG emissions thresholds, and no GHG emissions reduction plan with established GHG emissions reduction strategies have been adopted in the City or County. However, APCD staff has examined options for GHG thresholds for CEQA documents. Among the approaches discussed, APCD prefers consistency with the South Coast Air Quality Management District (AQMD) (APCD, 2011). The South Coast AQMD is considering a tiered approach with locally adopted GHG reduction plans followed by GHG threshold values set to capture 90 percent of project GHG emissions by project type. SCAQMD's current proposed threshold is 3,000 metric tons per year (SCAQMD, "Proposed Tier 3 Screening Levels - Residential/Commercial Projects, September 2010).

Emissions of CO2 from construction and operation of the 37 residential units, hangars, and storage units/light industrial uses, as well as demolition of the 13 existing residences, were

estimated using California Emissions Estimator Model (CalEEMod). Maximum daily CO2 emissions generated by construction of the buildings, which were amortized over an estimated 30-year lifetime, total 1,030 MT per year and operation of the currently proposed buildings would generate an estimated 1,891 MT per year (See Appendix A). This is a conservative estimate that assumes full development of Airpark-2 with light industrial uses and storage.

Emissions would be less than 3,000 MT per year of CO2 and would not exceed the SCAQMD proposed threshold and impacts would be less than significant.

Hazards and Hazardous Materials

Transport, Use, and Disposal of Hazardous Materials The Airpark Specific Plan MND identifies a significant but mitigable impact related to the potential for workers to be exposed to asbestos containing materials during Airpark-2 demolition activities for development. Mitigation Measure HAZ-1, which requires compliance with District Rule 62.7, Asbestos - Demolition and Renovation, would reduce impacts to a less than significant level. The updates to the Specific Plan would not affect the demolition required for the development of the Specific Plan area and the updated Specific Plan requires that no materials classified as flammable or hazardous which exceed the

31 of 46 City of Santa Paula Airpark Specific Plan Addendum #2 to the Mitigated Negative Declaration

allowances listed under relevant Building/Fire Ordinances for the Occupancy can be stored or used in the plan area; therefore, the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Impacts to Schools The school closest to the Specific Plan area is Grace Thille Elementary School, approximately 0.2 miles north of the plan area. The Specific Plan is not anticipated to create health and safety hazards or hazardous materials. The updates to the Specific Plan would not affect the uses of the Specific Plan area or the likelihood of impacts to schools; therefore, the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Hazardous Materials Sites In 2007, the plan area was not on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5. The following databases were checked on June 5, 2014 for known hazardous materials contamination at the project site (these are the databases which compile hazardous material sites pursuant to Government Code Section 65962.5):

• Comprehensive Environmental Response, Compensation, and Liability Information System (CERCLIS) database; • Environmental Protection Agency EnviroMapper database; • California State Water Quality Control Board GeoTracker database; and • California Department of Toxic Substances Control EnviroStor database

The plan area does not include any open sites according to the databases; therefore, the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

32 of 46 City of Santa Paula Airpark Specific Plan Addendum #2 to the Mitigated Negative Declaration

Airport Land Use Plan The plan area is located within the Ventura County Transportation Commissions (VCTC) Airport Land Use Plan. The Airpark Specific Plan MND found impacts related to airport land use plan conflicts/hazards to be less than significant, as development would comply with the Federal Aviation Administration (FAA) requirements, including Runway Protection Zone limitations, as well as conforming to FAA height restrictions. The updates to the Specific Plan include an increase in maximum building height from 35 feet to 45 feet, which would also conform to FAA height restrictions. Development is limited to 25% lot coverage of the development area; this would also be adhered to under the updated Specific Plan. Therefore, the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Private Airstrips The plan area is located adjacent and contiguous to the Santa Paula Airport, a privately owned and operated public-use airport which serves General Aviation non-commercial flights. The Airpark Specific Plan MND found impacts related to airport safety hazards to be less than significant, as development would comply with the City's Airport Approach zone and FAA regulations. Development under the updated Specific Plan would also comply with the City's Airport Approach Zone and FAA regulations; therefore, the Specific Plan updates would not create any new significant impacts beyond those identified in the 2007 MND.

Emergency Response Plans and Emergency Evacuation Plans The Airpark Specific Plan MND found that the Specific Plan would not impair implementation of, or physically interfere with, an adopted emergency response plan or emergency evacuation plan. The updates to the Specific Plan do not affect the location of the Specific Plan area or any emergency plans; therefore, the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Fire Hazards The Airpark Specific Plan MND found that the Specific Plan would have a less than significant impact related to fire hazard zones. The plan area is located in a "high fire hazard" zone; therefore, per the request of the Santa Paula Fire Department, a minimum 39-foot fire buffer is proposed. The updates to the Specific Plan also include this fire buffer; therefore, the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

33 of 46 City of Santa Paula Airpark Specific Plan Addendum #2 to the Mitigated Negative Declaration

Surface Water Quality The Airpark Specific Plan MND determined that plan area development would have the potential to adversely impact surface water quality in the Santa Clara River. Impacts were found to be mitigable with implementation of mitigation measures HYD-1 and HYD-2, which require development and implementation of a Stormwater Pollution Prevention Plan and a Stormwater Management Plan. The drainage plan for the updated Specific Plan would be the same as the drainage plan assessed by the MND. With the described mitigation, the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Groundwater Recharge The Airpark Specific Plan MND determined that implementation of the Specific Plan would not involve any direct extraction or withdrawal of groundwater, deep excavation or significant new development that could adversely affect groundwater quantity or flows. The updates to the Specific Plan include a 2.69% increase in the building footprints, which would not affect groundwater recharge. The Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Drainage Patterns The Airpark Specific Plan MND determined that the development of the Specific Plan would not substantially alter regional drainage patterns or the rate or amount of runoff. With the mitigation measures described, the development of Airpark-1 would not result in a significant increase in erosion, siltation or flooding on or near the plan area. The updates to the Specific Plan would not affect the regional drainage patterns or the rate or amount of runoff, as the building footprints would only increase by 2.69% and mitigation measures HYD-1 and HYD-2 would be required. The Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

34 of 46 City of Santa Paula Airpark Specific Plan Addendum #2 to the Mitigated Negative Declaration

Stormwater Drainage Systems Development of the Specific Plan was not found to add substantial runoff to existing stormwater drains since the intensity of development would not be substantially greater than what currently exists and development would be required to meet City requirements. The existing uses in the plan area have not changed since the MND was adopted and the updates to the Specific Plan would not add substantial runoff beyond what was expected from the 2007 Specific Plan. The Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Flooding The Specific Plan area is located within a zone that is subject to shallow flooding under a 100- year storm. The ground floor finished heights would be required to be one to two feet above the 100-year flood water surface elevation, as specified in the Specific Plan. The MND also found that the plan area experiences localized flooding problems during rain events. Mitigation Measure HYD-3, completion of a final hydraulic report, was required to reduce overall demands for stormwater control facilities, to minimize current flooding impacts and to address cumulative effects of the Specific Plan and other development within the City. The updates to the Specific Plan would also be subject to Mitigation Measure HYD-3 and would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Tsunamis, Seiches, or Mudflows The Airpark Specific Plan MND found no impact related to tsunamis, seiches, or mudflows, as the plan area is not located within an area subject to potential hazards of these types. The updates to the Specific Plan do not affect the location of the Specific Plan area or its proximity to tsunami, seiches, or mudflow hazard areas; therefore, the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

35 of 46 City of Santa Paula Airpark Specific Plan Addendum #2 to the Mitigated Negative Declaration

Land Use and Planning

Division of an Established Community The Airpark Specific Plan MND identifies a less than significant impact associated with the potential to divide an established community. Surrounding uses have not been substantially altered since the MND was adopted and the proposed uses would not be affected by the updates to the Specific Plan. Furthermore, the area is now zoned "Specific Plan" and the updates to the Specific Plan would be consistent with this zoning. Therefore, the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Conflicts with Land Use Plans, Policies, or Regulations The Airpark Specific Plan MND identifies no impacts associated with zoning, General Plan designations, or other land use plans, policies or regulations for the 2007 Specific Plan. Furthermore, the zoning for the plan area is now "Specific Plan", which would be compatible with the updates to the Specific Plan. Therefore, the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Habitat Conservation Plans The Airpark Specific Plan MND identifies no impact associated with habitat conservation plans, as the plan area was not subject to any such plans. Currently, no applicable habitat conservation plans exist; therefore, the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

36 of 46 City of Santa Paula Airpark Specific Plan Addendum #2 to the Mitigated Negative Declaration

Mineral Resources

No portion of the plan area is situation in a mineral resource zone. Specific Plan implementation would not utilize or reduce the availability of a known mineral resource. The updates to the Specific Plan do not affect the location of the plan area or its proximity to mineral resources; therefore, the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Noise

Sensitive Receptors The Airpark Specific Plan MND identifies a significant but mitigable noise impact related to the residential, industrial and business users that would be living and/or working within the plan area. There are no sensitive receptors in the area that would be affected by the development of the Specific Plan, but the residential/ business/ light industrial units that would be developed as part of the Specific Plan would be exposed to noise levels exceeding the City's established standards for residential noise.

Mitigation Measure N-1 requires project design features to ensure that the interior noise environment does not exceed 45 dBA. The proposed updates to the Specific Plan do not change the 37 residential/ light industrial/ business units that would be exposed to noise levels exceeding threshold. Application of Mitigation Measure N-1 would reduce this impact to a less than significant level and the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Traffic-Related Noise The Airpark Specific Plan MND identifies a less than significant impact associated with traffic generated by the Specific Plan. Trips generated by the Specific Plan would increase the traffic volume on the nearest segment of SR 126 by less than 1%. The updates to the Specific Plan do not include any development that would increase trips beyond what was analyzed in the MND. Therefore, the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

37 of 46 City of Santa Paula Airpark Specific Plan Addendum #2 to the Mitigated Negative Declaration

Construction-Related Noise The Airpark Specific Plan MND identifies a less than significant impact associated with construction noise. Although it would exceed the City's 65 dBA standard for daytime noise in residential areas, it would only occur between 8:00 AM and 6:00 PM Monday through Friday, and would therefore be exempt from the City's noise regulations. The updates to the Specific Plan do not substantially affect the amount of construction activity that would occur, the timing of the construction, or the noise that would result from the activity. Therefore, the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Airport Related-Noise The Airpark Specific Plan MND identifies a less than significant impact associated with airport- related noise from the Santa Paula Airport. The Airport Comprehensive Land Use Plan Update for Ventura County indicates that the plan area is located outside of the 60 dBA CNEL for 2020 conditions. The updates to the Specific Plan do not affect the location of the development and with implementation of Mitigation Measure N-1 the proposed sensitive receptors would not experience noise levels above 45 dBA. Therefore, the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Induce Population Growth

The Airpark Specific Plan MND identifies a less than significant impact related to the population growth induced by the Specific Plan development. According to the MND, the net population increase of 26 people would not exceed the Southern California Association of Governments (SCAG) population forecasts for 2005. The updates to the Specific Plan would not increase the number of residential/ light industrial/ business units or the expected population growth associated with the development and it would also not affect the City's ability to remain within the Ventura Council of Government's 2040 population forecast of 44,650. Therefore, the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

38 of 46 City of Santa Paula Airpark Specific Plan Addendum #2 to the Mitigated Negative Declaration

Population and Housing Displacement A future buildout of the Airpark-2 area of the Specific Plan would result in the demolition of the existing 13 non-conforming residential units on the site. The average household size for the City is 3.49 people; therefore, 45 people would be displaced. The proposed Airpark-1 updates to the Specific Plan would not affect the demolition required in both sub-zones. Adequate housing to accommodate any displaced residents is available within the region. As determined in the 2007 MND, new housing would not be necessitated by the demolition of the 13 existing plan area residences. Therefore, the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Public Services

Fire and Police Protection The Airpark Specific Plan MND identifies a less than significant impact related to the provision of fire and police protection services. Implementation of the Specific Plan was not found to have the potential to require the development of new fire or police facilities or increased personnel. The proposed updates to the Specific Plan would not include any changes to the service population of the plan area. As described in the MND, plan area developments would be required to contribute standard fees to offset the project's contribution to potential long-term service needs. Therefore, the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Schools The Airpark Specific Plan MND identifies a less than significant impact related to the provision of education services for the Specific Plan population. The proposed residential units would generate an estimated 22 students and the applicant(s) would be required to pay state- mandated school impact fees. The updates to the Specific Plan would not cause an increase in the number of students generated by the residential units and developers would be required to pay state-mandated school impact fees. Therefore, the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

39 of 46 City of Santa Paula Airpark Specific Plan Addendum #2 to the Mitigated Negative Declaration

Parks The Airpark Specific Plan MND identifies a less than significant impact related to the provision of parks. The 2007 Specific Plan was determined to generate a net increase of 26 people in the City, which would not be affected by the proposed updates. The currently proposed Specific Plan also includes the demolition of 13 existing residences and the development of 37 residential units; therefore, the expected net population increase would not be affected. Plan area developers would be required to pay City park impact fees; therefore, the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Other Public Facilities The Airpark Specific Plan MND identifies a less than significant impact related to the provision of public facilities. All developers are required to pay the City's standard development impact fees to offset potential impacts to other City services. The Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Recreation

Regional Parks and Other Recreational Facilities The Airpark Specific Plan MND identifies a less than significant impact related to the provision of parks and other recreational facilities. Developers would be required to pay City park impact fees, which provide funds to develop new park facilities and would offset any increase in demand. The Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

40 of 46 City of Santa Paula Airpark Specific Plan Addendum #2 to the Mitigated Negative Declaration

Circulation System Capacity The Airpark Specific Plan MND identifies a less than significant impact related to level of service impacts from the traffic generated by the proposed Specific Plan. The low volume of additional average daily trips (ADT) associated with the Specific Plan would not result in changes in level of service at any of the City's intersections. Individual developers within the plan area would be required to contribute to the City's traffic mitigation fee program to alleviate their incremental impact to the area intersections under cumulative conditions. They would also be required to pay applicable fees to the County of Ventura for cumulative impacts to the regional road network in accordance with the City's reciprocal fee agreement with the County. Payment of applicable fees would reduce impacts to a less than significant level and because the updates to the Specific Plan do not increase the number of trips generated by the development, they would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Air Traffic Patterns The Airpark Specific Plan MND identifies a less than significant impact related to air traffic patterns. The removal of residences from Airpark-2 may reduce air traffic safety hazards associated with the operation of the Santa Paula Airport, as they were permitted at the time of their construction, and therefore are allowed to remain, but are no longer permitted by the County's Airport Comprehensive Land Use plan. The updates to the Specific Plan would not affect air traffic patterns and the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Hazards and Emergency Access The Airpark Specific Plan MND identifies a less than significant impact related to emergency access and hazards. The plan area was designed to have the minimum sized cul-de-sac required at an entrance at Santa Maria Street to allow for truck maneuvering, as well as a fire access route to allow for emergency vehicle access. These and other safety design features would still be included in the updated Specific Plan. The Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

41 of 46 City of Santa Paula Airpark Specific Plan Addendum #2 to the Mitigated Negative Declaration

Parking Requirements The Airpark Specific Plan MND identifies a less than significant impact related to parking. Parking is no longer included in CEQA analysis and the updates to the Specific Plan would not affect the population or required parking for the development, which proposes 4.4 times the required guest parking, a surplus of 32 spaces. Therefore, the Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND. Alternative Transportation The Airpark Specific Plan MND identifies no impact related to adopted policies regarding alternative transportation measures. The Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Utilities and Service Systems

Wastewater The Airpark Specific Plan MND identifies a less than significant impact related to wastewater generation and treatment. The sewer line that the applicant proposed to construct would be constructed to meet City standards and the applicant would be required to obtain a connection approval from the City Engineer prior to discharge into the City's sewer system. Buildout would not generate more wastewater than could be transported and treated by the system as of 2007 and since then, a new wastewater treatment facility was made operational, further increasing the City's wastewater treatment capacity. The proposed updates to the Specific Plan would not increase the amount of wastewater generated by the Specific Plan development and the City's approval to build the sewer connection would be required. The Specific Plan updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Stormwater Flows The Airpark Specific Plan MND identifies a less than significant impact related to the stormwater system with implementation of mitigation measures HYD-1 and HYD-2, which require development and implementation of a Stormwater Pollution Prevention Plan and a

42 of 46 City of Santa Paula Airpark Specific Plan Addendum #2 to the Mitigated Negative Declaration

Stormwater Management Plan.

The updates to the Specific Plan would be subject to the same mitigation measures and would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Water Demand The City's drinking water supply is provided by groundwater pumped from the Santa Paula Basin. The City of Santa Paula is allocated 5,488 acre feet of water annually and the 7 year usage average is 4,911.8 acre feet for 2007-2013. With the five City owned deep wells, the water system can produce up to 10.6 million gallons per day (City of Santa Paula Water Master Plan, 2005). The City requires new development to pay all required fees related to water and provide sufficient water rights and water resource in-lieu fee for the entire development, per Santa Paula Municipal Code (SPMC).

The Airpark Specific Plan MND identifies a less than significant impact related to the water available to service the expected demand of the plan area. The updates to the Specific Plan would not affect the amount of water demanded by the plan area development and conservation techniques would still be required for the development of the Specific Plan. All applicants would be required to contribute to the City's water fee program to offset potential impacts. The updates to the Specific Plan would not create any new water demand beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Solid Waste The Airpark Specific Plan MND identifies a less than significant impact related to solid waste generation, recycling, and compliance with related programs and policies. The Specific Plan would be served by a landfill (Toland Road Landfill) which has the capacity to accommodate the plan area's solid waste generation. The updates would not alter the uses allowed within the Specific Plan area; therefore, they would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Mandatory Findings of Significance

Biological and Cultural Resources The Airpark Specific Plan MND identifies a significant but mitigable impact related to biological resources and cultural resources. Implementation of Mitigation Measure BIO-1 would reduce impacts to biological resources to a less than significant level and implementation of mitigation measures CR-1 and CR-2 would reduce impacts associated with the disturbance of unknown prehistoric and historic artifacts to a less than significant level. These mitigation measures would apply to the updated Specific Plan and the updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Short-Term and Long-Term Goals The Airpark Specific Plan MND identifies a significant but mitigable impact related to the achievement of short-term goals, to the disadvantage of long-term environmental goals. Implementation of mitigation measures AQ-1, BIO-1, CR-1, and CR-2 would ensure that long- term environmental goals are not disadvantaged as a result of the Specific Plan. The updates would not create any new significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Cumulatively Considerable Impacts The Airpark Specific Plan MND identifies a significant but mitigable impact related to impacts that are individually limited, but cumulatively considerable. Implementation of mitigation measures CR-1 and CR-2 would ensure that impacts to cultural resources are not cumulatively considerable. These mitigation measures would apply to the updated Specific Plan. The updates to the Specific Plan would not create any new cumulatively considerable significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

Adverse Effects on Human Beings The Airpark Specific Plan MND identifies a significant but mitigable impact related to negative environmental effects that would cause substantive adverse effects on human beings. Implementation of mitigation measures GEO-1, HYD-3, and N-1 would ensure that the Specific Plan would not have adverse effects on human beings. These mitigation measures would apply to the updated Specific Plan. The updates to the Specific Plan would not create

44 of 46 City of Santa Paula Airpark Specific Plan Addendum #2 to the Mitigated Negative Declaration

any new cumulatively considerable significant impacts beyond those identified in the MND or increase the severity of significant impacts identified in the MND.

CONCLUSION

The proposed updates to the Specific Plan are consistent with the City of Santa Paula General Plan and are within the growth parameters considered in the Airpark Specific Plan MND that was adopted by the City in 2007. Consequently, the proposed Specific Plan would not create any new significant impacts or increased severity impacts as compared to what was identified in the Airpark Specific Plan MND. Therefore, in accordance with CEQA Guidelines sections 15164 and Section 15162, an addendum is the appropriate environmental document under CEQA.
