To reduce the impacts of future development projects consistent with the proposed project, MM AIR-1a and MM AIR-1b are required. These mitigation measures would reduce emissions of VOC, NOX, PM10, and PM2.5 associated with the construction of future development projects in the Plan Area to the extent feasible. However, due to the size of the proposed project and the potential for overlapping construction activities, future development projects could still potentially exceed the Valley Air District regional thresholds, even with the implementation of mitigation. Therefore, project-related construction activities would result in significant and unavoidable regional air quality impacts.
Operational Emissions
Buildout of the proposed project would result in direct and indirect criteria air pollutant emissions from area, energy, and mobile sources. Area sources would include activities such as landscape maintenance and occasional architectural coatings. Energy sources would include electricity and natural gas combustion for space and water heating. Mobile sources would include vehicle trips associated with passenger cars. As previously discussed, the Valley Air District regional emission significance thresholds were used to determine the proposed project’s impact significance. The proposed Fresno SEDA Specific Plan policies emphasize development of mixed-use areas and improvements to active and public transit facilities that would contribute to reducing vehicle trips and VMT. As an example, the proposed project would create mixed use areas and would integrate distinct neighborhood commercial development areas that would provide daily services and amenities for the nearby residences and businesses.
Overall, the general proposed guiding principles and objectives for land use planning and the proposed land use changes and transportation improvements would contribute to reducing vehicle trips and VMT per service population to the extent feasible. Furthermore, existing General Plan policies would further reduce emissions from the operation of future projects in the Plan Area.
However, when compared to the existing land uses, due to the magnitude of planned growth in the Plan Area, implementation of the proposed project would generate significant emissions of criteria pollutants, and a net increase of approximately 602,972 in total regional VMT (see Appendix B).

As shown in this table, due to the magnitude of the proposed growth, operation of the land uses accommodated under the proposed project at buildout would generate air pollutant emissions that exceed the Valley Air District’s regional significance thresholds for VOC, NOX, CO, PM10, and PM2.5 at full buildout. Emissions of VOC and NOX that exceed the Valley Air District regional threshold would cumulatively contribute to the ozone nonattainment designation of the SJVAB. Emissions of NOX that exceed the Valley Air District’s regional significance thresholds would cumulatively contribute to the ozone and particulate matter nonattainment designations of the SJVAB. Emissions of direct PM10 and PM2.5 would contribute to the PM2.5 nonattainment designations.
The application of the Valley Air District Rule 9510 to future individual projects would contribute to reducing NOX and particulate matter emissions. In addition, application of Valley Air District Rule 9410 (Employer Based Trip Reduction) would contribute to reducing mobile source emissions from the operation of the proposed project. The objectives and policies included in the proposed Specific Plan would generally support a more sustainable development pattern to accommodate growth within the Plan Area by creating complete neighborhoods, high-density housing in proximity to jobs and service amenities, and supporting alternative transit options through improvements to the pedestrian, bicycle, public transportation, and alternative-fueled vehicle networks and infrastructure, which would contribute in minimizing long-term criteria air pollutant emissions.

Therefore, implementation of the proposed project would result in a significant impact because it would significantly contribute to the nonattainment designations of the SJVAB. To reduce emissions from the operation of future projects envisioned in the proposed project, MM AIR- 1c and MM AIR-1d are required to reduce emissions to the extent feasible, in combination with the existing General Plan policies applicable to the proposed project. However, due to the magnitude of emissions generated by the residential, office, and commercial land uses proposed as part of the proposed project, no mitigation measures are available that would reduce cumulative impacts below the Valley Air District’s thresholds. Therefore, despite adherence to the applicable mitigation measures, Impact AIR-2 would remain significant and unavoidable.
Impact Summary
Regional emissions generated by the proposed project would exceed applicable thresholds after compliance with all rules, regulations, and mitigation measures during operation. Localized operational emissions would also present a potentially significant impact after incorporation of identified mitigation. This impact would be significant and unavoidable.
Level of Significance Before Mitigation
Potentially significant impact.
Mitigation Measures
Implement MM AIR-1a through MM AIR-1d.
Level of Significance After Mitigation
Significant and unavoidable impact.
Buildout of the proposed project would occur over approximately 25 years, or longer. Construction activities associated with buildout of the proposed project could generate short-term emissions that exceed the Valley Air District’s significance thresholds during this time and cumulatively contribute to the nonattainment designations of the SJVAB. The General Plan policies and the implementation of MM AIR-1a and MM AIR-1b would reduce criteria air pollutant emissions from construction- related activities to the extent feasible. However, specific construction time frames and equipment for individual site-specific projects are not available and there is a potential for multiple developments to be constructed at any one time, resulting in potentially significant cumulative construction-related emissions.
Buildout in accordance with the proposed project would generate long-term emissions that would exceed the Valley Air District’s regional significance thresholds and cumulatively contribute to the nonattainment designations of the SJVAB. To reduce emissions from the operation of future projects envisioned in the proposed project, MM AIR-1c is required to reduce operation emissions to the extent feasible, in combination with the existing General Plan policies.

However, due to the magnitude of emissions generated by the residential, office, and commercial land uses proposed as part of the proposed project, no mitigation measures are available that would reduce cumulative impacts below the Valley Air District’s thresholds. Therefore, Impact AIR-2 would remain significant and unavoidable.
Sensitive Receptors Exposure to Pollutant Concentrations Impact AIR-3 The proposed project would expose sensitive receptors to substantial pollutant concentrations.
Impact Analysis
Sensitive Receptors
Those who are sensitive to air pollution include children, the elderly, and persons with preexisting respiratory or cardiovascular illness. The Valley Air District considers a sensitive receptor to be a location that houses or attracts children, the elderly, people with illnesses, or others who are especially sensitive to the effects of air pollutants. Examples of sensitive receptors include hospitals, residences, convalescent facilities, and schools.
Construction: ROG
ROG is emitted during the application of architectural coatings (painting). The amount emitted is dependent on the amount of ROG (or VOC) in the paint. ROG emissions are typically an indoor air quality health hazard concern rather than an outdoor air quality health hazard concern. Therefore, exposure to ROG during architectural coatings is a less than significant health impact.
There are three types of asphalt that are typically used in paving: asphalt cements, cutback asphalts, and emulsified asphalts. However, District Rule 4641 prohibits the use of the following types of asphalt: rapid cure cutback asphalt; medium cure cutback asphalt; slow cure asphalt that contains more than 0.5 percent of organic compounds that evaporate at 500°F or lower; and emulsified asphalt containing organic compounds, in excess of 3 percent by volume, that evaporate at 500°F or lower. An exception to this is medium cure asphalt when the National Weather Service official forecast of the high temperature for the 24-hour period following application is below 50°F.
The acute (short-term) health effects from worker direct exposure to asphalt fumes include irritation of the eyes, nose, and throat. Other effects include respiratory tract symptoms and pulmonary function changes. The studies were based on occupational exposure of fumes. Residents are not in the immediate vicinity of the fumes; therefore, they would not be subjected to concentrations high enough to evoke a negative response. In addition, the restrictions that are placed on asphalt in the San Joaquin Valley reduce ROG emissions from asphalt and exposure. The impact to nearby sensitive receptors from ROG during construction is less than significant.
Operation: ROG
During operation, ROG would be emitted primarily from motor vehicles. Direct exposure to ROG from project motor vehicles would not result in health effects, because the ROG would be City of Fresno—Fresno Southeast Development Area Specific Plan Project Air Quality Recirculated Draft Program EIR

The concentrations would not be great enough to result in direct health effects.
Construction and Operation: NOX, PM10, and PM2.5
As discussed in Impact AIR-2, construction and operation of future individual development projects accommodated under the proposed Specific Plan could potentially result in an exceedance of the Valley Air District’s ambient air quality screening threshold of 100 pounds per day.
As stated, the planned improvements, objectives and policies under the proposed Specific Plan would generally support a sustainable development pattern in accommodating future growth within the Plan Area, which would generally contribute to reducing long-term criteria air pollutant emissions. In addition, application of the Valley Air District Rule 9510 and Regulation VIII would contribute to reducing operation- and construction-related NOX and particulate matter emissions.
Furthermore, Rule 9410 would also contribute to reducing operation-related mobile source emissions.
However, while individual development projects may not result in exceeding the screening threshold of 100 pounds per day, the projected cumulative emissions associated with future development projects accommodated under the proposed Specific Plan would be in exceedance and could result in causing an exceedance of the AAQS. Therefore, as construction and operation of future individual development projects accommodated under the proposed Specific Plan could result in causing or contribute to a violation of the AAQS, impacts to air quality would be significant.
Toxic Air Contaminants
During construction and operation, the proposed project could result in emissions of several TACs that could potentially impact nearby sensitive receptors. The Valley Air District has defined health risk significance thresholds. These thresholds are represented as a cancer risk to the public and a non-cancer hazard from exposures to TACs. Cancer risk represents the probability (in terms of risk per million individuals) that an individual would contract cancer resulting from exposure to TACs continuously over a period of several years. The Valley Air District’s latest threshold of significance for TAC emissions is an increase in cancer risk for the maximally exposed individual of 20 in a million (formerly 10 in a million). Exposures to TACs can also result in both short-term (acute) or long-term (chronic) non-cancer health impacts. Such impacts could include illnesses related to reproductive effects, respiratory effects, eye sensitivity, immune effects, kidney effects, blood effects, central nervous system, birth defects, or other adverse environmental effects.
Project construction would involve the use of diesel-fueled vehicles and equipment that emit DPM, which is considered a TAC. Industrial land uses, such as chemical processing facilities, chrome-plating facilities, dry cleaners, and gasoline-dispensing facilities, have the potential to be substantial stationary sources that would require a permit from the Valley Air District for emissions of TACs.
Emissions of TACs would be controlled through permits issued by the Valley Air District and would be subject to further study and an HRA prior to the issuance of any necessary air quality permits. In addition to stationary/area sources of TACs, commercial and industrial operations could generate a substantial amount of DPM emissions from off-road equipment use and truck idling. New land uses in the proposed Plan Area that use diesel trucks, including trucks with transport refrigeration units, City of Fresno—Fresno Southeast Development Area Specific Plan Project Recirculated Draft Program EIR Air Quality

As it is not possible to determine the amount of TAC concentrations at the time of this analysis, it is not possible to calculate the risks for a particular health effect within the Plan Area. The proposed project is a programmatic project and until specific future projects are proposed, the associated TAC emissions cannot be determined or modeled at this time. Through the implementation of MM AIR- 1d, future development projects subject to environmental review under CEQA would be required to analyze potential TAC emissions and include mitigation as appropriate.
ARB developed a guidance document, Air Quality and Land Use Handbook: A Community Health Perspective (ARB Handbook), to address the siting of sensitive land uses in the vicinity of freeways, distribution centers, rail yards, ports, refineries, chrome-plating facilities, dry cleaners, and gasoline- dispensing facilities. This guidance document was developed to assess compatibility and associated health risks when placing sensitive receptors near existing pollution sources. ARB’s recommendations for the siting of new sensitive land uses were based on a compilation of studies that evaluated data on the adverse health effects from proximity to air pollution sources. The key observation in these studies is that proximity to air pollution sources substantially increases both exposure and the potential for adverse health effects. Respiratory and cardiovascular problems including asthma, lung cancer, and premature death have been associated with living near major roadways and freeways.
Children who live near major roadways and freeways have been found to have higher asthma rates and reduced lung function. There are three carcinogenic TACs that constitute the majority of the known health risks from motor vehicle traffic: DPM from trucks and benzene and butadiene from passenger vehicles. It has been found that outdoor concentrations are highest near the roadway and decrease with increasing distance downwind of the source. The ARB recommends avoiding siting new sensitive land uses within 500 feet of urban roads with more than 100,000 vehicles per day or rural roads with more than 50,000 vehicles per day.28 MM AIR-1d requires that an HRA be performed and potential health impacts be mitigated.
Future development envisioned as a part of the proposed project would be required to comply with AB 2588, and ARB standards for diesel engines. While existing City policies and regulations are intended to minimize impacts associated with sensitive receptors, mitigation measures for future project developments that implement these policies and regulations are identified to ensure that the intended environmental protections are achieved. Compliance with MM AIR-1d would help to ensure that mobile sources of TACs not covered under the Valley Air District permits are considered during subsequent project-level environmental review. This mitigation measure requires the preparation of project-specific technical health risk assessments for certain discretionary large industrial or warehousing uses to evaluate operational-related health risk impacts to further ensure that operational-related emissions are reduced to a less than significant level. However, information regarding operational characteristics of future specific development projects and the associated emissions cannot be determined at the time of this analysis; therefore, cumulative growth within the

In addition to operational emissions from new stationary sources of emissions and vehicle trips to and within the Plan Area, the proposed project would locate new sensitive receptors (residents) that could be subject to existing sources of TACs within the proposed project boundary. The California Supreme Court in California Building Industry Association v. Bay Area Air Quality Management District concluded that agencies generally subject to CEQA are not required to analyze the impact of existing environmental conditions on a project’s future users or residents.
Compliance with existing regulatory programs, General Plan policies, and MM AIR-1d will serve to reduce the health risk impacts of the proposed project to the extent feasible. However, the proposed project would result in the future development of numerous projects, each contributing incrementally to air emissions affecting sensitive receptors. Thus, it is possible that the proposed project would result in cumulatively significant impacts to sensitive receptors, even if individual projects were each less than significant. This is particularly likely since none of the measures herein would prevent multiple development projects from being constructed concurrently within close proximity to sensitive receptors in such a manner as to cause substantial concentrations within the area. Further, neither the amount of construction occurring nor the exact location within the Plan Area is foreseeable and, as such, it cannot be determined whether the resultant construction emissions could be adequately controlled or reduced to below regulatory thresholds. Without such information, it is not possible to conclude that air pollutant emissions resulting from construction activities would be adequately reduced to the point that sensitive receptors are not exposed to substantial concentrations of air pollutants, and thus a significant and unavoidable impact may result.
Level of Significance Before Mitigation
Potentially significant impact.
Mitigation Measures
Implement MM AIR-1d.
Level of Significance After Mitigation
Significant and unavoidable impact.
Existing regulations and ordinances would reduce operation-related impacts by reducing air pollutant emissions from stationary and mobile sources. Even with the implementation of new project-specific mitigation measures, cumulative operational emissions resulting from future development would likely exceed Valley Air District thresholds, contributing to the nonattainment designation of the SJVAB for the health-based State and national AAQS. Therefore, the potential impacts from the proposed project to sensitive receptors would be significant and unavoidable.

Impact AIR-4 The proposed project would not result in other emissions (such as those leading to odors) adversely affecting a substantial number of people.
Impact Analysis
Odors can cause a variety of responses. The impact of an odor is dependent on interacting factors such as frequency (how often), intensity (strength), duration (in time), offensiveness unpleasantness), location, and sensory perception. While offensive odors rarely cause any physical harm, they still can be very unpleasant, leading to considerable distress and often generating citizen complaints to local governments and regulatory agencies.
Growth within the proposed Plan Area could generate new sources of odors. Odors from the types of land uses that could generate objectional odors (see Table 3.3-7) are regulated under Regulation IV, Prohibitions, Rule 4102, Nuisance, which states:
A person shall not discharge from any source whatsoever such quantities of air contaminants or other materials which cause injury, detriment, nuisance or annoyance to any considerable number of persons or to the public or which endanger the comfort, repose, health or safety of any such person or the public or which cause or have a natural tendency to cause injury or damage to business or property.
As further discussed in the “Methodology” section, the Valley Air District has published recommended screening distances, as included in Table 3.3-7, and guidance documentation related to odors, which has been referenced for this analysis.
Construction-related Odors
Potential sources that may emit odors during construction activities include exhaust from diesel construction equipment. However, because of the temporary nature of these emissions, the intermittent nature of construction activities, and the highly diffusive properties of diesel exhaust, nearby receptors would not be affected by diesel exhaust odors associated with project construction. Odors from these sources would be localized and generally confined to the immediate area surrounding the proposed project site. The proposed project would utilize typical construction techniques, and the odors would be typical of most construction sites and temporary in nature.
Impacts would be less than significant.
Operational-related Odors
Industrial land uses have the potential to generate objectionable odors. Examples of industrial projects are wastewater treatment plants, compost facilities, landfills, solid waste transfer stations, fiberglass manufacturing facilities, paint/coating operations (e.g., auto body shops), dairy farms, petroleum refineries, asphalt batch manufacturing plants, chemical manufacturing, and food manufacturing facilities. Agricultural operations, such as the existing agricultural land uses currently included in the Plan Area, may also generate odors.
Future developments in the Plan Area could include light industrial land uses such as wastewater treatment plants, and so there is the potential for land uses typically considered to be associated City of Fresno—Fresno Southeast Development Area Specific Plan Project Air Quality Recirculated Draft Program EIR
3.3-58 FirstCarbon Solutions

The proposed project would also develop different types of residential and retail activities, which are not typical odor-generating land uses. Potential impacts from odor sources would be mitigated through compliance with General Plan Policy PU-9-d and by enforcement actions by agencies with regulatory authority over odors. General Plan Policy PU-9-d would ensure that waste and recycling facilities are properly located. The Valley Air District addresses odor issues through Rule 4102– Nuisance. Facilities creating nuisance odors generating public complaints can result in Valley Air District enforcement action.
Future individual development projects consistent with the proposed project will be required to determine whether odors would be a potentially significant impact as part of CEQA review. In addition, projects containing sensitive receptors are likely to be proposed near existing odor sources, such as agricultural operations. Projects proposing new receptors within screening level distances will reduce the impact to less than significant levels. Proposal of a new source within the screening distance would require the applicant to demonstrate that the proposed facility includes odor controls within its design and through implementation of odor management practices to reduce odors to less than significant.
Development consistent with the proposed project could also result in sensitive receptors being constructed within the screening level distances from existing odor sources. These potential odor impacts on new sensitive receptors could be significant. When potential odor impacts on these new sensitive receptors occur, the Valley Air District has authority under Rule 4102 to require the owner of the odor-generating source to take actions that would reduce impacts to less than significant. The Valley Air District provided a record of all odor complaints within the Plan Area from 2018 through 2021 for known sources of odors. No significant odor complaints have been received in the Plan Area or in the vicinity of the proposed project in recent years.
In addition to the existing regulatory programs described above, MM AIR-4 requires developers of projects with the potential to generate significant odor to prepare an odor impact assessment and to implement odor control measures. Compliance with MM AIR-4 would further reduce potential impacts of objectionable odors to below a level of significance. Additionally, implementation of the proposed project’s policies would help to minimize the effects of growth and development on air quality.
Level of Significance Before Mitigation
Potentially significant impact.
Mitigation Measures
MM AIR-4 Prior to future discretionary project approval in the Fresno Southeast Development Area Specific Plan Area (Plan Area), development project applicants proposing a project with the potential to generate significant odor impacts, as determined through review of San Joaquin Valley Air Pollution Control District (Valley Air District) odor complaint history for similar facilities and consultation with the Valley Air District, shall prepare an odor impact assessment and shall implement odor control measures recommended by the Valley Air District or the City as needed to reduce the impact to a level deemed acceptable by the Valley Air District.

Less than significant impact.
3.3.5 - Cumulative Impacts
The geographic scope of the cumulative impact analysis for Air Quality is the SJVAB. This analysis evaluates whether impacts of the Specific Plan, together with impacts of cumulative development, would result in a cumulatively significant impact with respect to air quality emissions. This analysis then considers whether incremental contribution of the impacts associated with implementation of the Specific Plan would be significant. Both conditions must apply for cumulative effects to rise to the level of significance.
In accordance with the Valley Air District’s methodology, any project that produces a significant project-level regional air quality impact in an area that is in nonattainment contributes to the cumulative impact. Because of the extent of the area potentially impacted from cumulative project emissions (i.e., the SJVAB); the Valley Air District considers a project cumulatively significant when project-related emissions exceed the regional emissions thresholds, as discussed in Impact AIR-2 and Impact AIR-3. No significant cumulative impacts were identified with regard to CO hotspots.
Criteria Pollutants
The SJVAB is designated nonattainment for ozone and PM2.5, under the California and national AAQS and nonattainment for PM10 under the California AAQS. Construction of cumulative projects will further degrade the regional and local air quality. Air quality will be temporarily impacted during construction activities. As discussed in Impact AIR-2, construction emissions associated with the proposed Plan would exceed the Valley Air District’s regional construction emissions thresholds for VOC, NOX, CO, PM2.5, and PM10. and NOX, after implementation of MM AIR-1a and MM AIR-1b. Thus, the proposed project’s contribution to cumulative air quality impacts would be cumulatively considerable and therefore significant.
For operational air quality emissions, any project that does not exceed or can be mitigated to less than the annual regional threshold values is not considered by the Valley Air District to be a substantial source of air pollution and does not add significantly to a cumulative impact. As discussed, the Valley Air District Rules 9510 and 9410 would contribute to reducing emissions of NOX and particulate matter associated with future individual projects accommodated under the proposed Specific Plan and may reduce impacts for these individual development projects to a less than significant level. In addition, the planned improvements, design guidelines, objectives, and policies under the proposed Specific Plan would generally support a more sustainable development pattern in the Plan Area. Creation of more complete neighborhoods, with high-density housing located in proximity to jobs and amenities, in addition to improving the public transit, pedestrian, and bicycle networks and infrastructure would contribute to reducing per capita VMT. However, due to the amount of growth for the proposed Plan Area, operation of the cumulative projects accommodated under the proposed Plan would result in emissions in excess of the Valley Air District regional emissions thresholds for VOC, NO
X, CO, PM10, and PM2.5 after implementation of MM AIR-
1c. Thus, the proposed Specific Plan’s criteria air pollutant emissions would be cumulatively considerable and therefore significant.

The proposed project would permit residential, office, commercial and industrial land uses.
Development of the land uses that are allowed under the proposed project may result in stationary sources of TAC emissions, including light industrial facilities, warehouses, dry cleaners, restaurants with charbroilers, or buildings with emergency generators and boilers. While MM AIR-1d would serve to reduce the potential health impacts of TAC emissions in the Plan Area, there is not enough information currently available to quantify the emissions of specific project development that may occur as a part of the proposed project to guarantee a less than significant finding. Furthermore, the construction and operation of multiple projects in the Plan Area may lead to a cumulatively considerable, and therefore significant, amount of TAC emissions.
Objectionable Odors Exposure
As discussed in Impact AIR-4, potential odor sources associated with the proposed project may result from construction equipment exhaust and the application of asphalt and architectural coatings during construction activities; however, construction odor emissions would be temporary, short- term, and intermittent in nature and would cease upon completion of the respective phase of construction and is thus considered less than significant. Although it is possible other construction activities could occur in proximity concurrent with construction of the proposed project, due to the short duration and intermittent nature of construction-related odors, impacts would be less than cumulatively considerable.
For long-term operation, the proposed project and other cumulative developments would be required to comply with Valley Air District Rule 4102 to prevent occurrences of public nuisances, as well as MM AIR-4, which would require potential future odor-generating industrial projects to mitigate potential impacts. Therefore, odors associated with the proposed project operations would be less than cumulatively considerable.
Level of Cumulative Significance Before Mitigation
Potentially significant impact.
Cumulative Mitigation Measures
Implement MM AIR-1a through MM AIR-1d and MM AIR-4.
Level of Cumulative Significance After Mitigation
Significant and unavoidable impact.
As discussed above, while implementation of MM AIR-1a through MM AIR-1d would serve to reduce criteria air pollutant and TAC emissions generated by the proposed project, there is currently not enough information to quantify emissions of specific project development that may occur under the proposed project. Without quantification to guarantee a less than significant finding, future development projects may still exceed the Valley Air District regional significance thresholds.
Additionally, due to the size of the proposed project, there is not sufficient mitigation available to reduce the potential criteria pollutant emissions associated with the proposed project to levels that would not exceed the Valley Air District thresholds of significance. Therefore, cumulative impacts to air quality would be considered to remain significant and unavoidable.

3.4.1 - Introduction
This section describes the existing biological setting and potential effects from project implementation on the project site and the surrounding area. This section also identifies mitigation measures to reduce these potential effects to less than significant levels. Descriptions and analysis in this section are based, in part, on the Fresno General Plan (General Plan), the Fresno Southeast Development Area (SEDA) Specific Plan (Specific Plan), the Fresno Municipal Code (Municipal Code), aerial photographs and maps, existing reports relevant to the Specific Plan area (Plan Area), and the results of database searches.
As further discussed in Chapter 1, Introduction, seven public comments were received during the Draft Program Environmental Impact Report (Draft PEIR) scoping period related to the proposed project’s potential biological resources impact:
• Requests that the Draft PEIR analyzes potential impacts on the special-status species identified in the comment letter and provides necessary mitigation measures to reduce impacts to a less than significant level.

The City’s developed land accounts for approximately 63 percent of the of the City and its SOI and is mostly comprised of commercial, residential, and industrial buildings. The City’s developed areas also include roads and parking lots. Approximately 32 percent of the Plan Area contains previously disturbed agricultural lands, orchards, pasture, and row and field crops, located predominately along the outer boundaries of the City and its SOI. Undeveloped and undisturbed areas with native vegetation occur within the remaining 5 percent of the City and its SOI. Further descriptions of these types of vegetation communities, as described in the General Plan, are included in Table 3.4-2, below.

Community Type Description
Irrigated Row
and Field Crops
Irrigated Row and Field Crops land occurs most frequently in floodplains or upland areas with high soil quality. Irrigated row and field crows include annual and perennial crops, grown in rows, with open space between the rows. Row and field crops are artificially irrigated and feature a moderate disturbance rate by vehicle and pedestrian encroachment typically associated with farming activities. Species composition changes frequently, both by season and by year.
Deciduous
Orchard
Deciduous orchard communities primarily occur where there are flat alluvial soils on valley floors, rolling foothills and relatively steep slopes. Orchard communities are typically comprised of artificially irrigated habitat dominated by one, sometimes several, tree or shrub species planted for cultivation. Trees are typically low and bushy, and the understory is open, with little groundcover. In the City and its SOI, deciduous orchards include a variety of fruit trees (e.g., apples, apricots, cherries, citrus, kiwi, peaches, nectarines, pears, persimmons, plums, pluots, pomegranates, etc.) and/or nut trees and shrubs (e.g., almonds, olives, pistachios, walnuts, etc.). Understory species generally consist of short native and non-native grasses and other herbaceous species.
Lacustrine Lacustrine communities consist of standing/open waters in topographic depressions (i.e., lakes) or dammed river channels. Lacustrine communities lack persistent emergent vegetation but may have submerged or floating-leaved aquatic vegetation. Generally, lacustrine systems are surrounded by hydrophytic plants, grasses, and trees.
Annual
Grassland
Annual grassland communities includes a mix of native and non-native, annual grasses, which often occur in association with ruderal herbs and occasional native annual forbs. The dominant plant species within the annual grassland vegetation community typically include black needlegrass (Nasella sp.), fescue (Vulpia sp.), brome (Bromus sp.), and wild oats (Avena spp), with mustard (Brassica nigra), dove weed (Eremocarpus setigerus), and poppy (Eschscholzia sp.). These grasses germinate with the fall rains, grow during the winter and spring, and wither in the early summer.
Valley Foothill
Riparian
Valley Foothill Riparian communities within the City and its SOI occur primarily within mature riparian forests along the San Joaquin River corridor. They typically have a 20 to 80 percent canopy cover with trees that are winter deciduous. Wild grape (Vitis californica) often provides 30 to 50 percent ground cover. There is very little herbaceous understory with the exception of disturbed openings in the canopy cover. The understory typically consists of leaf-litter, fallen limbs, and is often impenetrable for smaller herbaceous plants.
Tree canopy species within this community typically includes cottonwood (Populus fremontii), California sycamore (Platanus racemosa), and valley oak (Quercus lobata).
Subcanopy species often includes white alder (Alnus rhombifolia), boxelder (Acer negundo), and Oregon ash (Fraxinus latifolia). Typical understory shrub layer plants include wild grape, California blackberry (Rubus ursinus), blue elderberry (Sambucus caerulea), poison oak (Toxicodendron diversilobum), and willows (Salix sp.).
Riverine Riverine systems consist of linear aquatic communities of flowing, non-tidal waters with a distinct channel and little to no persistent emergent vegetation. Riverine systems may also include areas with abundant submerged or floating-leaved aquatic vegetation. Vegetation communities abutting riverine systems tend to be dominated by trees, shrubs, persistent emergent vegetation, and/or emergent mosses and lichens. This vegetation community occurs near or depends upon a nearby freshwater source or areas with fresh water flow during all or part of the year.
Valley Oak
Woodland
Valley oak woodland communities vary from open-canopy savanna-like woodlands to partially closed canopy woodlands but mostly consist of winter deciduous, broad-leaved City of Fresno—Fresno Southeast Development Area Specific Plan Project Biological Resources Recirculated Draft Program EIR

Community Type Description
species. Valley oak (Quercus lobata), a winter deciduous species and California’s largest broad-leaved tree, is usually the only tree species present, although blue oak (Q. douglasii) may also be present. Mature valley oaks can reach heights of 50 to 100 feet (about 15 to 35 meters). Valley oak woodlands typically occur on deep, well-drained alluvial soils in valley bottoms that have a higher summer moisture content. This community intergrades with valley oak riparian near rivers and with blue oak woodlands on drier slopes. Characteristic understory species include creeping wild rye (Elymus triticoides), wild oats (Avena sp.), brome (Bromus sp.), barley (Hordeum zp.), needlegrass (Nassella sp.), and poison oak (Toxicodendron diversilobum).
Barren Barren communities are areas in which the vegetative cover comprises less than 10 percent of the surface area (disregarding natural rock outcrops) and where there is evidence of soil surface disturbance and compaction from previous legal human activity, and/or areas in which the vegetative cover is greater than 10 percent, soils surface compaction is evident, and building foundations and debris are present (e.g., irrigation piping, fencing, old wells, abandoned farming or mining equipment) from legal activities (as opposed to illegal dumping). Vegetation within barren land has a high predominance of non-native or weedy species that are indicators of soil disturbance, including Russian thistle (Salsola tragus), telegraph weed (Heterotheca grandiflora), horehound (Marrubium vulgare), and sow thistle (Sonchus oleraceus), and a sub-dominance of non-native grasses. Barren land only provides moderately suitable habitat for one special-status species, California horned lark.
Pasture Pasture lands form a dense habitat with nearly 100 percent cover; usually monoculture crops are planted in these areas, which are irrigated, artificially seeded, and frequently maintained. Characteristic species include non-native grasses such as oat (Avena sp.), bermuda grass (Cynodon sp.), barley (Hordeum sp.), Sorghum grass, as well as clover (Medicago sp.). Often times, this land contains significant areas of bare ground due to livestock grazing and movement across acres of this vegetation community.
Northern
Claypan Vernal
Pool
The northern claypan vernal pool community is located in an area that is surrounded by a lacustrine vegetation community in the northern portion of the City. Typically, these pools are located within the lower elevations of the main San Joaquin Valley. These areas are typically associated with a series of small mima mounds with interspersed pools. Typically, these pools have highly alkaline and may display whitish salt deposits in non-vegetated centers of dry pools. These vernal pools are dominated by a high percentage of non-native species.
