NOISE SETTING

NOISE DESCRIPTORS
Sound is mechanical energy transmitted by pressure waves in a compressible medium such as air.

Noise is generally considered to be unwanted sound. Sound is characterized by various parameters that describe the rate of oscillation of sound waves, the distance between successive troughs or crests, the speed of propagation, and the pressure level or energy content of a given sound. In particular, the sound pressure level has become the most common descriptor used to characterize the loudness of an ambient sound level.

The decibel (dB) scale is used to quantify sound pressure levels. Although decibels are most commonly associated with sound, "dB" is a generic descriptor that is equal to ten times the logarithmic ratio of any physical parameter versus some reference quantity. For sound, the reference level is the faintest sound detectable by a young person with good auditory acuity.

Since the human ear is not equally sensitive to all sound frequencies within the entire auditory spectrum, human response is factored into sound descriptions by weighting sounds within the range of maximum human sensitivity more heavily in a process called “A-weighting,” written as dB(A). Any further reference in this discussion to decibels written as "dB" should be understood to be A-weighted.

Time variations in noise exposure are typically expressed in terms of a steady-state energy level equal to the energy content of the time varying period (called LEQ), or alternately, as a statistical description of the sound pressure level that is exceeded over some fraction of a given observation period. Finally, because community receptors are more sensitive to unwanted noise intrusion during the evening and at night, state law requires that, for planning purposes, an artificial dBA increment be added to quiet time noise levels in a 24-hour noise descriptor called the Ldn (daynight) or the Community Noise Equivalent Level (CNEL). The CNEL metric has gradually replaced the Ldn factor, but the two descriptors are essentially identical.

CNEL-based standards are generally applied to transportation-related sources because local jurisdictions are pre-empted from exercising direct noise control over vehicles on public streets, aircraft, trains, etc. The City of Calimesa therefore regulates the noise exposure of the receiving property through land use controls.

For “stationary” noise sources, or noise sources emanating from private property the City does have legal authority to establish noise performance standards designed to not adversely impact adjoining uses. These standards are typically articulated in the Municipal Code. These standards recognize the varying noise sensitivity of both transmitting and receiving land uses. The property line noise performance standards are normally structured according to land use and time-of-day.

NOISE STANDARDS
Calimesa
For stationary noise sources located proximate to residential uses, the City of Calimesa proposes the noise exposure planning policy contained in Section 8.15.040 of the Municipal Code. These Calimesa Creek N 2
noise standards must be met at the nearest sensitive receptors in the vicinity of any stationary or operational source of noise originating from the project. The policy applies to any on-site activities and are shown in Table 1

Noise from construction equipment is exempt for the regulations in Table 1 but is required to adhere to noise standards as stated in Section 8.15.080 of the Municipal Code:
“It is unlawful for any person, including the city, to operate any single or a combination of powered construction equipment at any construction site before 7:00 a.m. or after 7:00 p.m.

In addition, it is unlawful for any person, including the city, to operate any single or a combination of powered construction equipment at any construction site before 10:00 a.m. or after 5:00 p.m. on Saturdays and Sundays, January 1st, the last Monday in May, known as “Memorial Day,” July 4th, the first Monday in September, Thanksgiving Day and December 25th. When January 1st, July 4th, or December 25th fall on a Sunday, it is unlawful for any person to operate any single or a combination of powered construction equipment at any construction site before 10:00 a.m. or after 5:00 p.m. on the following Monday”
In addition to these times of day construction requirements, the Municipal Code also requires that construction related noise will not exceed a level of 75 dBA for more than 8 hours during a 24- hour period. There are permissible deviations to this standard if construction only occurs sporadically as shown in Table 2.

Yucaipa
Section 87.0905 of the Yucaipa Municipal Code outlines the noise standards applicable to projects within its jurisdiction. The City has adopted the following standards for emanations from any source as it affects adjacent properties.

Other Commercial Anytime 60

In Section 87.0905(e), Exempt Noises, temporary construction, repair, or demolition activities between 7am and 7pm, except Sundays and Federal holidays are exempted from these noise standards.

The City of Yucaipa also has a vibration standard in its Municipal Code Section 87.0910. However, construction is exempt from this requirement if it occurs between 7 a.m. and 7 p.m., except Sundays and Federal holidays.

GROUNDBORNE VIBRATION
Vibration is an oscillatory motion through a solid medium in which the motion’s amplitude can be described in terms of displacement, velocity, or acceleration. Vibration is normally associated with activities such as railroads or vibration-intensive stationary sources but can also be associated with Calimesa Creek N 4
construction equipment such as jackhammers, pile drivers, and hydraulic hammers. Vibration displacement is the distance that a point on a surface move away from its original static position.

The instantaneous speed that a point on a surface move is described as the velocity and the rate of change of the speed is described as the acceleration. Each of these descriptors can be used to correlate vibration to building damage, and acceptable equipment vibration levels.

During construction, the operation of construction equipment can cause groundborne vibration.

This type of vibration is best measured in terms of velocity or acceleration. The peak particle velocity (PPV) or the root mean square (RMS) velocity is usually used to describe vibration amplitudes. The units for PPV velocity is normally inches per second (in/sec). PPV is defined as the maximum instantaneous peak of the vibration signal and is considered appropriate for evaluating potential building damage. Typically, groundborne vibration generated by human activities attenuates rapidly with distance from the source of the vibration.

BASELINE NOISE LEVELS
The City’s of Calimesa and Yucaipa are located in in Riverside County near the San Bernardino County border. The proposed storm drain pipeline will be located within the roadway right-ofway on County Line Road between 5th Street and the I-10. The proposed detention basin will be located on the south side of County Line Road and the west side of 3 rd Street.

Noise measurements were made in order to document existing baseline levels in the area on Tuesday, September 3, 2019. Measurements were made between 1:00 and 2:30 a.m. and were located to be representative of both the pipeline and detention basin activities. The results are shown below in Table 4.

Table 4

The noise meter was located on County Line Road near the entrance to the Holiday Ranch Mobile Home Park. This location is in proximity to the I-10 freeway. A noise level of almost 62 dBA Leq was observed.

Farther east from the I-10 freeway the observed noise levels were lower. At the proposed basin site adjacent to the County Line Road perimeter observed noise levels ranged from 54-56 dBA Leq.

Monitoring experience has shown that 24-hour weighted CNELs are typically 2 to 3 dB higher than mid-day Leq readings (Caltrans Technical Noise Supplement, 2009). This would equate to existing CNELs in the 64-65 dBA range at the front facades of noise-sensitive uses adjacent to the Calimesa Creek N 5
pipeline installation. At the location of the proposed basin, existing noise levels would equate to 56-59 dBA CNEL.

PROJECT NOISE IMPACTS

THRESHOLDS OF SIGNIFICANCE
According to the current CEQA Appendix G guidelines, noise impacts are considered potentially significant if they result in:
a. Generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the Project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies.
b. Generation of excessive groundborne vibration or groundborne noise levels. c. For a Project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the Project expose people residing or working in the Project area to excessive noise levels.

The noise impact assessment evaluates short-term (temporary) impacts associated with project construction as well as long-term (permanent) impacts resulting from project operation. For construction noise, the potential for impacts is assessed by considering several factors, including the proximity of construction-related noise sources to sensitive receptors, typical noise levels associated with construction equipment (including construction-related vehicles), the potential for construction noise levels to interfere with adjacent residential activities, the duration that sensitive receptors would be affected, and whether proposed activities would occur outside the construction time limits specified in the Noise Ordinance. The project is not expected to create any long-term operational noise increases associated with either the basin, diversion structures, tie-ins or storm drain installation.

Construction noise is typically governed by ordinance limits on allowable times of equipment operations and requires a noise level of less than 75 dBA Leq at a receiving property. The City of Calimesa limits the hours of construction operation to be between the hours of 7:00 a.m. and 7:00 p.m. on weekdays and 10:00 a.m. and 5:00 p.m. on Saturdays or Sundays or holidays. The City of Yucaipa exempts noise generated from construction activities as long as it occurs between 7:00 a.m. and 7:00 p.m. on weekdays and Saturdays with no construction on Sundays or federal holidays.

SENSITIVE RECEPTORS
There are scattered residences along the storm drain alignment. The closest residences have an approximate 50-foot setback from the roadway centerline. The area surrounding the tie-ins have similar setbacks. Because the two activities have similar construction sequences they are analyzed as a single component.

There are residences surrounding the detention basin site on County Line Road and 3 rd Street. The
closest homes take access from 3rd Street and are immediately adjacent to the eastern basin Calimesa Creek N 7
property line. The basin is approximately 480 feet in diameter. The closest home has an approximate 50-foot separation from the basin perimeter and almost a 300-foot separation from the site center. At completion, the top of the basin will be at ground level and the bottom will be approximately -25 feet below grade. When equipment operates at the lower elevation, noise will fall off dramatically because of the shielding offered by the below ground pit. Therefore, sensitive uses adjacent to the retention basin will experience progressively lower construction noise as construction progresses.

The low-flow water diversion structure is within Calimesa Creek adjacent to and west of 5th Street and east of Park Avenue. There are a few scattered homes to the south with an approximate 75- foot setback. The multi-family homes to the north, across County Line Road have a larger setback.

CONSTRUCTION NOISE IMPACTS
Construction noise levels would vary at any given receptor depending on the construction phase, equipment type, duration of use, distance between the noise source and receptor, and the presence or absence of barriers between the noise source and receptor. For this analysis, construction noise levels were estimated for proposed daytime construction.

The construction noise analysis shows that the nearby sensitive residential receivers will likely experience a temporary/periodic increase above ambient noise levels. Construction noise is unavoidable though noise would be temporary and limited to the duration of the construction in any one location. These temporary impacts will cease once each portion of pipeline is completed.

In 2006, the Federal Highway Administration (FHWA) published the Roadway Construction Noise Model that includes a national database of construction equipment reference noise emissions levels. In addition, the database provides an acoustical usage factor to estimate the fraction of time each piece of construction equipment is operating at full power during a construction phase. The usage factor is a key input variable that is used to calculate the average Leq noise levels.

Table 5 identifies highest (Lmax) noise levels associated with each type of equipment identified for use, then adjusts this noise level for distance to the closest sensitive receptors and the extent of equipment usage (usage factor), which is represented as Leq.

Quantitatively, the primary noise prediction equation is expressed as follows for the hourly average noise level (Leq) at distance D between the source and receiver (dBA):

Leq = Lmax @ 50’ – 20 log (D/50’) + 10log (U.F%/100) – I.L.(bar) Where:

Lmax @ 50’ is the published reference noise level at 50 feet U.F.% is the usage factor for full power operation per hour I.L.(bar) is the insertion loss for intervening barriers Calimesa Creek N 8
Point sources of noise emissions are attenuated by a factor of 6 dB per doubling of distance through geometrical (spherical) spreading of sound waves.

Noise impacts would be significant if they caused a violation of any adopted standards. The daytime noise standard is 75 dBA Leq. For the detention basin, as shown in Table 6, modeling equipment in the site center (some equipment may be closer others farther), will not cause an exceedance of standards even if 2-3 pieces of equipment were operating simultaneously. In addition, at the perimeter there will be a 3 to 3.5-foot masonry wall. The top of the basin is at ground level and the basin progressively gets deeper and deeper towards the center of the site for an ultimate depth of -25 feet from the surface.

Calimesa Creek N 9
As construction progresses equipment will be located below ground level. The equipment operational height together with the 3 to 3.5-foot masonry wall will provide an effective 28-foot height differential at the basin bottom. This will provide at least -15 dBA of noise attenuation for the adjacent residences. Therefore, at the start of construction, when equipment operates directly at the property line, noise levels might be slightly in excess of the 75 dBA Leq goal. However, as construction progresses, attenuation due to distance and elevation differential will reduce noise levels at any receptor to 44-52 dBA Leq.

The low-flow diversion structure varies in width but is an average of 75 feet from the two singlefamily residences to the south. It is not expected that noise levels will exceed the 75 dBA Leq goal as shown in Table 7. Most adjacent sensitive receptors are the multi-family units to the north, across County Line Road with an approximate 150-foot setback distance. If structures within 75 feet are not expected to be exposed to a construction noise level in excess of the noise goal, then the multi-family units to the north with a 150-foot setback would experience an even greater level of noise protection.

At the closest residential setback of 50 feet, noise levels along the various storm drain alignments and main line tie-ins are estimated to range between 72 and 78 dBA (Leq). The noisiest activities occur during pavement excavation. These maximal noise levels are limited to the time it takes to remove pavement (if necessary) and dig trenches. The project engineer estimates the linear progress rate for the pipeline is 100 feet per day. Equipment operating adjacent to any residence would be brief and would affect a given sensitive receptor for only a short period of time. While such noise levels will be noticeable at times, these exceedances would be sporadic (not continuous) in nature, limited in duration, and would occur only when equipment is typically operated within 50 feet of a given receptor. By 75 feet, noise levels would be below 75 dBA Leq. Additionally, as seen in Table 2, the Calimesa Noise Code allows for upward adjustment of the noise standard when equipment operates for less than 8 hours. Although difficult to estimate, any single piece of heavy equipment will only operate within 50 feet of a residence for a short time and not 8 straight hours. For example, for 2 hours of continuous noise, the construction threshold is adjusted upward by +6 dBA such that the resultant noise threshold increases to 81 dBA and construction noise would not exceed the standard.

Additionally, activities are limited to daytime hours when most people are away. According to the City of Calimesa Municipal Code, permissible hours of construction are between the hours of 7:00 a.m. and 7:00 p.m. on weekdays and 10:00 a.m. and 5:00 p.m. on Saturdays or Sundays or holidays.

Although the City of Yucaipa does not have any regulations on construction noise levels, compliance with the Calimesa requirements would provide assurance that construction noise levels are not intrusive. The City of Yucaipa only allows construction between the hours of 7:00 a.m. and 7:00 p.m. on weekdays and Saturdays. No construction is permitted on Sundays or holidays.

These hours are included as conditions on any project construction permits and these limits will serve to minimize any adverse construction noise impact potential. Because maximum storm drain installation noise would occur for only a few days near any noise-sensitive land use, and because the detention basin occurs over a large site that ultimately is at an elevation of -25 feet below grade, construction activity noise impacts are considered less-than-significant.

Calimesa Creek N 10

CONSTRUCTION ACTIVITY VIBRATION
Project-related pavement cutting, excavation and construction activities could result in vibration that could disturb nearby residents and cause cosmetic damage to existing adjacent buildings or structures.

Ground-borne vibration occurs when heavy equipment travels over unpaved surfaces or when it is engaged in soil movement. The effects of ground-borne vibration include discernable movement of building floors, rattling of windows, shaking of items on shelves or hanging on walls, and rumbling sounds. Vibration related problems generally occur due to resonances in the structural components of a building because structures amplify groundborne vibration. Within the “soft” sedimentary surfaces of much of Southern California, ground vibration is quickly damped out.

Groundborne vibration is almost never annoying to people who are outdoors (FTA 2006).

Groundborne vibrations from construction activities rarely reach levels that can damage structures.

Because vibration is typically not an issue, very few jurisdictions have adopted vibration significance thresholds. Vibration thresholds have been adopted for major public works construction projects, but these relate mostly to structural protection (cracking foundations or stucco) rather than to human annoyance.

The vibration descriptor commonly used to determine structural damage is the peak particle velocity (ppv) which is defined as the maximum instantaneous positive or negative peak of the vibration signal, usually measured in in/sec. The range of such vibration is as follows in Table 8:

Table 8
Human Response To Transient Vibration
Average Human Response ppv (in/sec)
Severe 2.00
Strongly perceptible 0.90 0
Distinctly perceptible 0.24 0
Barely perceptible 0.03 0
5 Source: Caltrans Transportation and Construction Vibration Guidance Manual, 2013.

Over the years, numerous vibration criteria and standards have been suggested by researchers, organizations, and governmental agencies. There are no Caltrans or Federal Highway Administration standards for vibration.

According to Caltrans, the threshold for structural vibration damage for modern structures is 0.5 in/sec for intermittent sources, which include impact pile drivers, pogo-stick compactors, crackand-seat equipment, vibratory pile drivers, and vibratory compaction equipment. The American Association of State Highway and Transportation Officials (AASHTO) (1990) identifies maximum vibration levels for preventing damage to structures from intermittent construction or maintenance activities for residential buildings in good repair with gypsum board walls to be 0.4– Calimesa Creek N 11

0.5 in/sec. Below this level there is virtually no risk of building damage. Table 9 shows the predicted vibration levels generated by construction equipment.

Source: FHWA Transit Noise and Vibration Impact Assessment The calculation to determine PPV at a given distance is:

PPVdistance = PPVref*(25/D)^1.5
Where:

PPVdistance = the peak particle velocity in inches/second of the equipment adjusted for distance,
PPVref = the reference vibration level in inches/second at 25 feet, and D = the distance from the equipment to the receiver.

As shown even equipment operating very near a residence would not cause damage although the vibration could be in the annoyance range. Regardless, is unlikely that a large bulldozer or loaded truck would ever operate 10 feet from a structure. Therefore, vibration levels will be any possible cosmetic damage level.

SITE OPERATIONAL NOISE
Operation of the detention basins, low-flow diversion structures and drains and tie-ins would not result in significant noise impacts, since these facilities would be located below ground surface.

SUMMARY
Short-term construction noise intrusion and vibration impacts will be limited by conditions on construction permits requiring compliance with the City of Calimesa Noise Ordinance. The allowed hours of construction are between the hours of 7:00 a.m. and 7:00 p.m. on weekdays and 10:00 a.m. and 5:00 p.m. on Saturdays or Sundays or holidays. The City of Yucaipa’s allowable Calimesa Creek N 12
hours of construction are 7:00 a.m. and 7:00 p.m. on weekdays and Saturdays. In addition, the following standard construction practices are required:
• All construction equipment shall use properly operating mufflers. • Stockpiling and staging activities must be located as far as practicable from dwellings. • All mobile equipment shall have properly operating and maintained mufflers.

Construction vibration would not exceed any damage thresholds at the nearest sensitive uses.

Operation of the project would not result in significant noise impacts.

Reference: Truck Haul Route for Calimesa Channel Stage 3 Detention Basin Vehicle Miles Traveled Assessment
The Truck Haul Route for Calimesa Channel Stage 3 Detention Basin (Project) was evaluated for local transportation effects as detailed in Truck Haul Route for Calimesa Channel 3 Detention Basin to San Timoteo Landfill Traffic Impact Study dated October 30, 2019 prepared by Stantec Consulting Services Inc. (Stantec). That traffic impact analysis used level of service (LOS) methodology based on vehicle delay calculations to determine peak hour intersection impacts. Senate Bill 743 (SB 743) has replaced LOS with “Vehicle Miles Traveled” (VMT) as the metric for identifying California Environmental Quality Act (CEQA) transportation impacts. This memorandum summarizes the potential environmental transportation impacts of the Project consistent with SB 743.

The proposed Project consists of the exportation of dirt from the Calimesa Channel 3 detention basin during a two- to three-month construction period. The proposed truck haul route covers approximately 11 miles from the Calimesa Channel Stage 3 detention basin to the San Timoteo Landfill in Redlands.

VEHICLE MILES TRAVELED
SB 743 has identified VMT as the metric for identifying CEQA transportation impacts. To comply with the requirements of SB 743, the City of Calimesa has defined the conditions for conducting CEQA VMT analysis.1 The City has identified project types that are local serving by nature as having the presumption of a less than significant impact. The City uses VMT per service population for its impact threshold.

The Project consists of truck trips from the detention basin construction site to the San Timoteo Landfill during the temporary construction period. The truck haul route would be active only during the two- to three-month construction period, and VMT analysis is not applicable to temporary construction traffic. Furthermore, these approximately 11-mile trips would be considered local serving trips.

CONCLUSIONS
The Project consists of a temporary truck haul route during construction of the Calimesa Channel Stage 3 Detention Basin. VMT is not applicable to temporary construction traffic. Since the Project consists of hauling of dirt from the construction site over only a two- to three-month period, no further VMT analysis is required. 1 City of Calimesa, CA. May 2020.

ATMOSPHERIC SETTING

REGIONAL CLIMATE
The climate of the Calimesa area, as with all of Southern California, is governed largely by the strength and location of the semi-permanent high-pressure center over the Pacific Ocean and the moderating effects of the nearby vast oceanic heat reservoir. Local climatic conditions are characterized by very warm summers, mild winters, infrequent rainfall, moderate daytime onshore breezes, and comfortable humidities. Unfortunately, the same climatic conditions that create such a desirable living climate combine to severely restrict the ability of the local atmosphere to disperse the large volumes of air pollution generated by the population and industry attracted in part by the climate. The City of Calimesa is located within Riverside County near the San Bernardino County line. The project is situated in an area where the pollutants generated in coastal portions of the Los Angeles basin undergo photochemical reactions and then move inland during the daily sea breeze cycle with limited regional meteorological dispersion potential.

Winds across the proposed Calimesa project site are an important meteorological parameter because they control both the initial rate of dilution of locally generated air pollutant emissions as well as controlling their regional trajectory. The wind patterns in this portion of Riverside County display a very unidirectional onshore flow from the west-southwest/west-northwest that is strongest in summer with a weaker offshore return flow from the north-northeast/east-northeast that is strongest on winter nights when the land is colder than the ocean. The onshore winds during the day average 6-10 mph while the offshore flow is often calm or drifts slowly westward at 1-3 mph. During the daytime, any locally generated air emissions are thus rapidly transported eastward toward the Banning Pass/Palm Springs, or upslope within the rising thermal chimneys on the south slopes of the San Bernardino Mountains without generating any localized air quality impacts. The nocturnal drainage winds which move slowly across the area have some potential for localized stagnation, but fortunately, these off-shore winds have their origin in the nearby mountains where background pollution levels are low such that any localized contributions do not create any unhealthful impacts.

In conjunction with the two characteristic wind regimes that affect the rate and orientation of horizontal pollutant transport, there are two similarly distinct types of temperature inversions that control the vertical depth through which pollutants are mixed. The summer on-shore flow is capped by a massive dome of warm, sinking air which caps a shallow layer of cooler ocean air.

These marine/ subsidence inversions act like a giant lid over the basin. They allow for local mixing of emissions, but they confine the entire polluted air mass within the basin until it escapes into the desert or along the thermal chimneys formed along heated mountain slopes. In winter, when the air near the ground cools while the air aloft remains warm, radiation inversions are formed that trap low-level emissions such as automobile exhaust near their source. As background levels of primary vehicular exhaust rise during the seaward return flow, the combination of rising non-local baseline levels plus emissions trapped locally by these radiation inversions creates micro-scale air pollution "hot spots" near freeways, shopping centers and other traffic concentrations in coastal areas of the Los Angeles Basin. The combination of winds and inversions are critical determinants in leading to the often degraded air quality in summer, and the generally good air quality in winter in the Calimesa area.

AIR QUALITY SETTING

AMBIENT AIR QUALITY STANDARDS (AAQS)
In order to gauge the significance of the air quality impacts of the proposed project, those impacts, together with existing background air quality levels, must be compared to the applicable ambient air quality standards. These standards are the levels of air quality considered safe, with an adequate margin of safety, to protect the public health and welfare. They are designed to protect those people most susceptible to further respiratory distress such as asthmatics, the elderly, very young children, people already weakened by other disease or illness, and persons engaged in strenuous work or exercise, called "sensitive receptors." Healthy adults can tolerate occasional exposure to air pollutant concentrations considerably above these minimum standards before adverse effects are observed. Recent research has shown, however, that chronic exposure to ozone (the primary ingredient in photochemical smog) may lead to adverse respiratory health even at concentrations close to the ambient standard.

National AAQS were established in 1971 for six pollution species with states retaining the option to add other pollutants, require more stringent compliance, or to include different exposure periods.

The initial attainment deadline of 1977 was extended several times in air quality problem areas like Southern California. In 2003, the Environmental Protection Agency (EPA) adopted a rule, which extended and established a new attainment deadline for ozone for the year 2021. Because the State of California had established AAQS several years before the federal action and because of unique air quality problems introduced by the restrictive dispersion meteorology, there is considerable difference between state and national clean air standards. Those standards currently in effect in California are shown in Table 1. Sources and health effects of various pollutants are shown in Table 2.

The Federal Clean Air Act Amendments (CAAA) of 1990 required that the U.S. Environmental Protection Agency (EPA) review all national AAQS in light of currently known health effects.

EPA was charged with modifying existing standards or promulgating new ones where appropriate.

EPA subsequently developed standards for chronic ozone exposure (8+ hours per day) and for very small diameter particulate matter (called "PM-2.5"). New national AAQS were adopted in 1997 for these pollutants.

Planning and enforcement of the federal standards for PM-2.5 and for ozone (8-hour) were challenged by trucking and manufacturing organizations. In a unanimous decision, the U.S.

Supreme Court ruled that EPA did not require specific congressional authorization to adopt national clean air standards. The Court also ruled that health-based standards did not require preparation of a cost-benefit analysis. The Court did find, however, that there was some inconsistency between existing and "new" standards in their required attainment schedules. Such attainment-planning schedule inconsistencies centered mainly on the 8-hour ozone standard. EPA subsequently agreed to downgrade the attainment designation for a large number of communities to “non-attainment” for the 8-hour ozone standard.

Evaluation of the most current data on the health effects of inhalation of fine particulate matter prompted the California Air Resources Board (ARB) to recommend adoption of the statewide PM-2.5 standard that is more stringent than the federal standard. This standard was adopted in 2002. The State PM-2.5 standard is more of a goal in that it does not have specific attainment planning requirements like a federal clean air standard, but only requires continued progress towards attainment.

Similarly, the ARB extensively evaluated health effects of ozone exposure. A new state standard for an 8-hour ozone exposure was adopted in 2005, which aligned with the exposure period for the federal 8-hour standard. The California 8-hour ozone standard of 0.07 ppm is more stringent than the federal 8-hour standard of 0.075 ppm. The state standard, however, does not have a specific attainment deadline. California air quality jurisdictions are required to make steady progress towards attaining state standards, but there are no hard deadlines or any consequences of nonattainment. During the same re-evaluation process, the ARB adopted an annual state standard for nitrogen dioxide (NO2) that is more stringent than the corresponding federal standard and strengthened the state one-hour NO2 standard.

As part of EPA’s 2002 consent decree on clean air standards, a further review of airborne particulate matter (PM) and human health was initiated. A substantial modification of federal clean air standards for PM was promulgated in 2006. Standards for PM-2.5 were strengthened, a new class of PM in the 2.5-to-10-micron size was created, some PM-10 standards were revoked, and a distinction between rural and urban air quality was adopted. In December 2012, the federal annual standard for PM-2.5 was reduced from 15 g/m3 to 12 g/m3 which matches the California AAQS. The severity of the basin’s non-attainment status for PM-2.5 may be increased by this action and thus require accelerated planning for future PM-2.5 attainment.

In response to continuing evidence that ozone exposure at levels just meeting federal clean air standards is demonstrably unhealthful, EPA had proposed a further strengthening of the 8-hour standard. A new 8-hour ozone standard was adopted in 2015 after extensive analysis and public input. The adopted national 8-hour ozone standard is 0.07 ppm which matches the current California standard. It will require three years of ambient data collection, then 2 years of nonattainment findings and planning protocol adoption, then several years of plan development and approval. Final air quality plans for the new standard are likely to be adopted around 2022.

Ultimate attainment of the new standard in ozone problem areas such as Southern California might be after 2025.

In 2010 a new federal one-hour primary standard for nitrogen dioxide (NO2) was adopted. This standard is more stringent than the existing state standard. Based upon air quality monitoring data in the South Coast Air Basin, the California Air Resources Board has requested the EPA to designate the basin as being in attainment for this standard. The federal standard for sulfur dioxide (SO2) was also recently revised. However, with minimal combustion of coal and mandatory use of low sulfur fuels in California, SO2 is typically not a problem pollutant.

BASELINE AIR QUALITY
Existing and probable future levels of air quality in the project area can be best inferred from ambient air quality measurements conducted by the South Coast Air Quality Management District (SCAQMD) at its Redlands air monitoring station located less than one mile west of the proposed site. That station, however, only monitors ozone and large particulates. The closest data resource for a more comprehensive spectrum of monitored pollutants is the Central San Bernardino monitoring station. Table 3 summarizes the last four years of published data from the Redlands and Central San Bernardino monitoring stations.

Ozone and particulates are seen to be the two most significant air quality concerns. Ozone is the primary ingredient in photochemical smog. Slightly more than 21 percent of all days exceed the California one-hour standard. The 8-hour state ozone standard has been exceeded an average of 31 percent of all days in the past four years. The federal 8-hour standard is exceeded 23 percent of all days. For the last four years, ozone levels have neither improved nor gotten noticeably worse.

While ozone levels are still high, they are much lower than 10 to 20 years ago. Attainment of all clean air standards in the project vicinity is not likely to occur soon, but the severity and frequency of violations is expected to continue to slowly decline during the current decade.

In addition to gaseous air pollution concerns, Riverside experiences frequent violations of standards for 10-micron diameter respirable particulate matter (PM-10). High dust levels occur during Santa Ana wind conditions, as well as from the trapped accumulation of soot, roadway dust and byproducts of atmospheric chemical reactions during warm season days with poor visibility.

Table 3 shows that two percent of all days in the last four years experienced a violation of the State PM-10 standard. However, the three-times less stringent federal standard has not been exceeded in the same time period.

A substantial fraction of PM-10 is comprised of ultra-small diameter particulates capable of being inhaled into deep lung tissue (PM-2.5). Peak annual PM-2.5 levels are sometimes almost as high as PM-10, which includes PM-2.5 as a sub-set. Only one day of all measurement days in the last four years experienced a violation of the 24-hour standard of 35 g/m3.

While many of the major ozone precursor emissions (automobiles, solvents, paints, etc.) have been substantially reduced, most major PM-10 sources (construction dust, vehicular turbulence along roadway shoulders, truck exhaust, etc.) have not been as effectively reduced. Prospects of ultimate attainment of ozone standards are better than for particulate matter.

More localized pollutants such as carbon monoxide, nitrogen oxides, etc. are very low near the project site because background levels, never approach allowable levels. There is substantial excess dispersive capacity to accommodate localized vehicular air pollutants such as NOx or CO without any threat of violating applicable AAQS.

AIR QUALITY PLANNING
The Federal Clean Air Act (1977 Amendments) required that designated agencies in any area of the nation not meeting national clean air standards must prepare a plan demonstrating the steps that would bring the area into compliance with all national standards. The SCAB could not meet the deadlines for ozone, nitrogen dioxide, carbon monoxide, or PM-10. In the SCAB, the agencies designated by the governor to develop regional air quality plans are the SCAQMD and the Southern California Association of Governments (SCAG). The two agencies first adopted an Air Quality Management Plan (AQMP) in 1979 and revised it several times as earlier attainment forecasts were shown to be overly optimistic.

The 1990 Federal Clean Air Act Amendment (CAAA) required that all states with air-sheds with “serious” or worse ozone problems submit a revision to the State Implementation Plan (SIP).

Amendments to the SIP have been proposed, revised and approved over the past decade. The most current regional attainment emissions forecast for ozone precursors (ROG and NOx) and for carbon monoxide (CO) and for particulate matter are shown in Table 4. Substantial reductions in emissions of ROG, NOx and CO are forecast to continue throughout the next several decades.

Unless new particulate control programs are implemented, PM-10 and PM-2.5 are forecast to slightly increase.

The Air Quality Management District (AQMD) adopted an updated clean air “blueprint” in August 2003. The 2003 Air Quality Management Plan (AQMP) was approved by the EPA in 2004. The AQMP outlined the air pollution measures needed to meet federal health-based standards for ozone by 2010 and for particulates (PM-10) by 2006. The 2003 AQMP was based upon the federal onehour ozone standard which was revoked late in 2005 and replaced by an 8-hour federal standard.

Because of the revocation of the hourly standard, a new air quality planning cycle was initiated.

With re-designation of the air basin as non-attainment for the 8-hour ozone standard, a new attainment plan was developed. This plan shifted most of the one-hour ozone standard attainment strategies to the 8-hour standard. As previously noted, the attainment date was to “slip” from 2010 to 2021. The updated attainment plan also includes strategies for ultimately meeting the federal PM-2.5 standard.

Because projected attainment by 2021 required control technologies that did not exist yet, the SCAQMD requested a voluntary “bump-up” from a “severe non-attainment” area to an “extreme non-attainment” designation for ozone. The extreme designation was to allow a longer time period for these technologies to develop. If attainment cannot be demonstrated within the specified deadline without relying on “black-box” measures, EPA would have been required to impose sanctions on the region had the bump-up request not been approved. In April 2010, the EPA approved the change in the non-attainment designation from “severe-17” to “extreme.” This reclassification set a later attainment deadline (2024), but also required the air basin to adopt even more stringent emissions controls.

Source: California Air Resources Board, 2013 Almanac of Air Quality In other air quality attainment plan reviews, EPA had disapproved part of the SCAB PM-2.5 attainment plan included in the AQMP. EPA stated that the current attainment plan relied on PM2.5 control regulations that had not yet been approved or implemented. It was expected that a number of rules that were pending approval would remove the identified deficiencies. If these issues were not resolved within the next several years, federal funding sanctions for transportation projects could result. The 2012 AQMP included in the current California State Implementation Plan (SIP) was expected to remedy identified PM-2.5 planning deficiencies.

The federal Clean Air Act requires that non-attainment air basins have EPA approved attainment plans in place. This requirement includes the federal one-hour ozone standard even though that standard was revoked almost ten years ago. There was no approved attainment plan for the onehour federal standard at the time of revocation. Through a legal quirk, the SCAQMD is now required to develop an AQMP for the long since revoked one-hour federal ozone standard. Because the current SIP for the basin contains a number of control measures for the 8-hour ozone standard that are equally effective for one-hour levels, the 2012 AQMP was believed to satisfy hourly attainment planning requirements.

AQMPs are required to be updated every three years. The 2012 AQMP was adopted in early 2013.

An updated AQMP was required for completion in 2016. The 2016 AQMP was adopted by the SCAQMD Board in March, 2017, and has been submitted the California Air Resources Board for forwarding to the EPA. The 2016 AQMP acknowledges that motor vehicle emissions have been effectively controlled and that reductions in NOx, the continuing ozone problem pollutant, may need to come from major stationary sources (power plants, refineries, landfill flares, etc.) The current attainment deadlines for all federal non-attainment pollutants are now as follows:
8-hour ozone (70 ppb) 2032
Annual PM-2.5 (12 g/m3) 2025
8-hour ozone (75 ppb) 2024 (old standard)
1-hour ozone (120 ppb) 2023 (rescinded standard)
Calimesa Creek AQ
- 11 -
24-hour PM-2.5 (35 g/m3) 2019
The key challenge is that NOx emission levels, as a critical ozone precursor pollutant, are forecast to continue to exceed the levels that would allow the above deadlines to be met. Unless additional stringent NOx control measures are adopted and implemented, ozone attainment goals may not be met.

The proposed project does not directly relate to the AQMP in that there are no specific air quality programs or regulations governing storm water improvement projects. Conformity with adopted plans, forecasts and programs relative to population, housing, employment and land use is the primary yardstick by which impact significance of planned growth is determined. The SCAQMD, however, while acknowledging that the AQMP is a growth-accommodating document, does not favor designating regional impacts as less-than-significant just because the proposed development is consistent with regional growth projections. Air quality impact significance for the proposed project has therefore been analyzed on a project-specific basis.

AIR QUALITY IMPACT

STANDARDS OF SIGNIFICANCE
Air quality impacts are considered “significant” if they cause clean air standards to be violated where they are currently met, or if they “substantially” contribute to an existing violation of standards. Any substantial emissions of air contaminants for which there is no safe exposure, or nuisance emissions such as dust or odors, would also be considered a significant impact.

Appendix G of the California CEQA Guidelines offers the following four tests of air quality impact significance. A project would have a potentially significant impact if it would:
a) Conflicts with or obstructs implementation of the applicable air quality plan. b) Results in a cumulatively considerable net increase of any criteria pollutants for which the Project region is non-attainment under an applicable federal or state ambient air quality standard.
c) Exposes sensitive receptors to substantial pollutant concentrations. d) Creates objectionable odors affecting a substantial number of people.

Primary Pollutants
Air quality impacts generally occur on two scales of motion. Near an individual source of emissions or a collection of sources such as a crowded intersection or parking lot, levels of those pollutants that are emitted in their already unhealthful form will be highest. Carbon monoxide (CO) is an example of such a pollutant. Primary pollutant impacts can generally be evaluated directly in comparison to appropriate clean air standards. Violations of these standards where they are currently met, or a measurable worsening of an existing or future violation, would be considered a significant impact. Many particulates, especially fugitive dust emissions, are also primary pollutants. Because of the non-attainment status of the South Coast Air Basin (SCAB) for PM-10, an aggressive dust control program is required to control fugitive dust during project construction.

Secondary Pollutants
Many pollutants, however, require time to transform from a more benign form to a more unhealthful contaminant. Their impact occurs regionally far from the source. Their incremental regional impact is minute on an individual basis and cannot be quantified except through complex photochemical computer models. Analysis of significance of such emissions is based upon a specified amount of emissions (pounds, tons, etc.) even though there is no way to translate those emissions directly into a corresponding ambient air quality impact.

Because of the chemical complexity of primary versus secondary pollutants, the SCAQMD has designated significant emissions levels as surrogates for evaluating regional air quality impact Calimesa Creek AQ
- 13 -
significance independent of chemical transformation processes. Projects with daily emissions that exceed any of the following emission thresholds are recommended by the SCAQMD to be considered significant under CEQA guidelines.

SENSITIVE RECEPTORS
There are residences surrounding the proposed detention basin site County Line Road near 3rd Street. The closest homes are immediately adjacent to the eastern site perimeter and take access from 3rd Street. The existing land uses adjacent to the proposed storm drain improvements from include vacant land and single-family detached residential units to the south and multi-family to the north in the City of Yucaipa. The closest residence is approximately 50 feet from the roadway centerline.

CONSTRUCTION ACTIVITY IMPACTS
CalEEMod was developed by the SCAQMD to provide a model by which to calculate both construction emissions and operational emissions from a variety of land use projects. It calculates both the daily maximum and annual average emissions for criteria pollutants as well as total or annual greenhouse gas (GHG) emissions.

The project entails construction of a 53 acre-foot detention basin at County Line Road near 3rd Street. Additionally, a storm drain system will run from between 5th Street and I-10. Tie-Ins will connect the new storm drain lines to the creek. A low-flow water diversion structure is proposed within Calimesa Creek. This concrete structure would allow low flow water in Calimesa Creek to be diverted west into the Calimesa Creek to maintain existing low water flows in the creek.

Estimated construction emissions were modeled using CalEEMod2020.4.0 to identify maximum daily emissions for each pollutant during project construction. The construction schedule and equipment list was provided by the project engineer and is shown in Table 6.

Construction equipment exhaust contains carcinogenic compounds within the diesel exhaust particulates. The toxicity of diesel exhaust is evaluated relative to a 24-hour per day, 365 days per year, 70-year lifetime exposure. The SCAQMD does not generally require the analysis of construction-related diesel emissions relative to health risk due to the short period for which the majority of diesel exhaust would occur. Health risk analyses are typically assessed over a 9-, 30-, or 70-year timeframe and not over a relatively brief construction period due to the lack of health risk associated with such a brief exposure.

LOCALIZED SIGNIFICANCE THRESHOLDS
The SCAQMD has developed analysis parameters to evaluate ambient air quality on a local level in addition to the more regional emissions-based thresholds of significance. These analysis elements are called Localized Significance Thresholds (LSTs). LSTs were developed in response to Governing Board’s Environmental Justice Enhancement Initiative 1-4 and the LST methodology was provisionally adopted in October 2003 and formally approved by SCAQMD’s Mobile Source Committee in February 2005.

Use of an LST analysis for a project is optional. For the proposed project, the only possible LST impact would be during construction. LSTs are applicable for a sensitive receptor where it is possible that an individual could remain for 24 hours such as a residence, hospital or convalescent facility.

LSTs are applicable to the following criteria pollutants: oxides of nitrogen (NOx), carbon monoxide (CO), and particulate matter (PM-10 and PM-2.5). LSTs represent the maximum emissions from a project that are not expected to cause or contribute to an exceedance of the most stringent applicable federal or state ambient air quality standard, and are developed based on the ambient concentrations of that pollutant for each source receptor area and distance to the nearest sensitive receptor.

LST screening tables are available for 25, 50, 100, 200 and 500 meter source-receptor distances.

For this project, there are residences adjacent to most project components such that the most conservative and restrictive 25-meter distance was modeled.

LST pollutant screening level concentration data is currently published for 1, 2 and 5 acre sites for varying distances. Because construction of a storm drain is linear, equipment only operates in front of any single residence for a short period of time (progress rate is estimated to be 100 linear feet per day). The most stringent thresholds for a 1 acre site were applied for storm drain activity.

However, the detention basin is larger such that thresholds for a 4-acre site were interpolated from available data. One acre-sites were used for other ancillary activities.

The following thresholds and emissions in Table 8 are therefore determined (pounds per day):

LSTs were compared to the maximum daily construction activities. Emissions are below the LST construction thresholds. LST impacts are less-than-significant.

OPERATIONAL IMPACTS
Because a detention basin is a passive structure requiring negligible long-term access, there are no operational air quality impacts associated with the proposed project. There should be a requirement for periodic desilting or vegetation removal, but the frequency and intensity of such actions is purely conjectural. There are no operational emissions associated with the project.

ODORS
The proposed detention pond is designed to not have a significant pool of water remaining after a storm event. Periodic cleaning of both vegetation and trash will ensure no smells arise because of rotting vegetation or other organic material.

CONSTRUCTION EMISSIONS MINIMIZATION
Construction activities are not anticipated to cause dust emissions to exceed SCAQMD CEQA thresholds. Nevertheless, emissions minimization through enhanced dust control measures is Calimesa Creek AQ
- 17 -
recommended for use because of the non-attainment status of the air and proximity of residential uses. Recommended measures include:

Fugitive Dust Control
• Apply soil stabilizers or moisten inactive areas.
• Water exposed surfaces as needed to avoid visible dust leaving the construction site (typically 2-3 times/day).
• Cover all stock piles with tarps at the end of each day or as needed. • Provide water spray during loading and unloading of earthen materials. • Minimize in-out traffic from construction zone
• Cover all trucks hauling dirt, sand, or loose material and require all trucks to maintain at least two feet of freeboard
• Sweep streets daily if visible soil material is carried out from the construction site Similarly, ozone precursor emissions (ROG and NOx) are calculated to be below SCAQMD CEQA thresholds. However, because of the regional non-attainment for photochemical smog, the use of reasonably available control measures for diesel exhaust is recommended. Combustion emissions control options include:

Exhaust Emissions Control
• Utilize well-tuned off-road construction equipment.
• Establish a preference for contractors using Tier 3 or better rated heavy equipment. • Enforce 5-minute idling limits for both on-road trucks and off-road equipment.

GREENHOUSE GAS EMISSIONS
“Greenhouse gases” (so called because of their role in trapping heat near the surface of the earth) emitted by human activity are implicated in global climate change, commonly referred to as “global warming.” These greenhouse gases contribute to an increase in the temperature of the earth’s atmosphere by transparency to short wavelength visible sunlight, but near opacity to outgoing terrestrial long wavelength heat radiation in some parts of the infrared spectrum. The principal greenhouse gases (GHGs) are carbon dioxide, methane, nitrous oxide, ozone, and water vapor. For purposes of planning and regulation, Section 15364.5 of the California Code of Regulations defines GHGs to include carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons and sulfur hexafluoride. Fossil fuel consumption in the transportation sector (onroad motor vehicles, off-highway mobile sources, and aircraft) is the single largest source of GHG emissions, accounting for approximately half of GHG emissions globally. Industrial and commercial sources are the second largest contributors of GHG emissions with about one-fourth of total emissions.

California has passed several bills and the Governor has signed at least three executive orders regarding greenhouse gases. GHG statues and executive orders (EO) include AB 32, SB 1368, EO S-03-05, EO S-20-06 and EO S-01-07.

AB 32 is one of the most significant pieces of environmental legislation that California has adopted. Among other things, it is designed to maintain California’s reputation as a “national and international leader on energy conservation and environmental stewardship.” It will have wideranging effects on California businesses and lifestyles as well as far reaching effects on other states and countries. A unique aspect of AB 32, beyond its broad and wide-ranging mandatory provisions and dramatic GHG reductions are the short time frames within which it must be implemented.

Major components of the AB 32 include:
• Require the monitoring and reporting of GHG emissions beginning with sources or categories of sources that contribute the most to statewide emissions. • Requires immediate “early action” control programs on the most readily controlled GHG sources.
• Mandates that by 2020, California’s GHG emissions be reduced to 1990 levels. • Forces an overall reduction of GHG gases in California by 25-40%, from business as usual, to be achieved by 2020.
• Must complement efforts to achieve and maintain federal and state ambient air quality standards and to reduce toxic air contaminants.

Statewide, the framework for developing the implementing regulations for AB 32 is under way.

Maximum GHG reductions are expected to derive from increased vehicle fuel efficiency, from greater use of renewable energy and from increased structural energy efficiency. Additionally, through the California Climate Action Registry (CCAR now called the Climate Action Reserve), general and industry-specific protocols for assessing and reporting GHG emissions have been Calimesa Creek AQ
- 19 -
developed. GHG sources are categorized into direct sources (i.e. company owned) and indirect sources (i.e. not company owned). Direct sources include combustion emissions from on-and offroad mobile sources, and fugitive emissions. Indirect sources include off-site electricity generation and non-company owned mobile sources.

THRESHOLDS OF SIGNIFICANCE
In response to the requirements of SB97, the State Resources Agency developed guidelines for the treatment of GHG emissions under CEQA. These new guidelines became state laws as part of Title 14 of the California Code of Regulations in March, 2010. The CEQA Appendix G guidelines were modified to include GHG as a required analysis element. A project would have a potentially significant impact if it:
• Generates GHG emissions, directly or indirectly, that may have a significant impact on the environment, or,
• Conflicts with an applicable plan, policy or regulation adopted to reduce GHG emissions.

Section 15064.4 of the Code specifies how significance of GHG emissions is to be evaluated. The process is broken down into quantification of project-related GHG emissions, making a determination of significance, and specification of any appropriate mitigation if impacts are found to be potentially significant. At each of these steps, the new GHG guidelines afford the lead agency with substantial flexibility.

Emissions identification may be quantitative, qualitative or based on performance standards.

CEQA guidelines allow the lead agency to “select the model or methodology it considers most appropriate.” The most common practice for transportation/combustion GHG emissions quantification is to use a computer model such as CalEEMod, as was used in the ensuing analysis.

The significance of those emissions then must be evaluated; the selection of a threshold of significance must take into consideration what level of GHG emissions would be cumulatively considerable. The guidelines are clear that they do not support a zero net emissions threshold. If the lead agency does not have sufficient expertise in evaluating GHG impacts, it may rely on thresholds adopted by an agency with greater expertise.

On December 5, 2008 the SCAQMD Governing Board adopted an Interim quantitative GHG Significance Threshold for industrial projects where the SCAQMD is the lead agency (e.g., stationary source permit projects, rules, plans, etc.) of 10,000 Metric Tons (MT) CO2 equivalent/year. In September 2010, the SCAQMD CEQA Significance Thresholds GHG Working Group released revisions which recommended a threshold of 3,000 MT CO2e for all land use projects. This 3,000 MT/year recommendation has been used as a guideline for this analysis.

In the absence of an adopted numerical threshold of significance, project related GHG emissions in excess of the guideline level are presumed to trigger a requirement for enhanced GHG reduction at the project level.

PROJECT RELATED GHG EMISSIONS GENERATION
Construction Activity GHG Emissions
The project is assumed to require less than one year for construction. During project construction, the CalEEMod2020.4.0 computer model predicts that the construction activities will generate the annual CO2e emissions identified in Table 9.

Amortized 14.2
CalEEMod Output provided in appendix
SCAQMD GHG emissions policy from construction activities is to amortize emissions over a 30- year lifetime. The amortized level is provided. GHG impacts from construction are considered less-than-significant.

CONSISTENCY WITH GHG PLANS, PROGRAMS AND POLICIES
The City of Calimesa prepared a Climate Action Plan in September 2014. The purpose was to integrate local planning efforts to reduce GHG emissions and improve the quality of life in the community. The Western Riverside Energy Leader Partnership (WRELP) Program builds upon the existing policies and programs in the region to analyze energy-sector emissions and propose energy conservation and renewable energy measures that reduce GHG emissions within Energy Action Plans for 11 jurisdictions served by SCE. The WRELP partners include Calimesa. The City of Yucaipa has not yet completed a finalized Greenhouse Gas Reduction Plan. The applicable GHG planning document is AB-32.

No recommendations or action items would apply to the proposed storm water project. Except for construction impacts there are no associated operational emissions. Therefore, since the project results in GHG emissions below the SCAQMD 3,000 ton threshold, the project would not conflict with any applicable plan, policy, or regulation to reduce GHG emissions.

The 28.2-acre review area is located south of County Line Road, east of Interstate 10, and west of 3rd Street in the City of Calimesa in Riverside County (Figure 1; Figures included in Appendix B). The review area is within U.S.

Geological Survey 7.5-minute Yucaipa quadrangle map, Sections 11, 12, 13, and 14 of Township 2 South, Range 2 West (Figure 2 of Appendix B). The review area consists of two discontinuous polygons separated by approximately 1,640 feet. The approximate center of the western polygon of the review area is longitude 117°03ʹ35″W and latitude 33°00ʹ14″N, and the approximate center of the of the eastern polygon of the review area is longitude 117°02ʹ56″W and latitude 33°00ʹ12″N.

To drive to the western polygon of the review area, take Interstate 10, exit on County Line Road, and head east.

Take Calimesa Boulevard and head south. Calimesa Creek is approximately 150 feet south of the intersection of County Line Road and Calimesa Boulevard on Calimesa Boulevard. The downstream portion of the western polygon of the review area starts approximately 380 feet west of Calimesa Boulevard. The remainder of the western polygon is approximately 135 feet west of the intersection of Calimesa Creek and 5th Street. To drive to the eastern polygon of the review area, head east on County Line Road from its intersection with Calimesa Boulevard. The eastern polygon of the review area is approximately 2,000 feet east of the intersection of 5th Street and County Line Road.

Item 5: Jurisdictional Delineation Methods
The ACOE wetlands delineation was performed in accordance with the 1987 U.S. Army Corps of Engineers Wetlands Delineation Manual (ACOE 1987), the Regional Supplement to the Corps of Engineers Wetland Delineation Manual:

Arid West Region (ACOE 2008a), A Field Guide to the Identification of the Ordinary High Water Mark (OHWM) in the Arid West Region of the Western United States: A Delineation Manual (ACOE 2008b), and guidance provided by ACOE and the U.S. Environmental Protection Agency on the geographic extent of jurisdiction based on the U.S.

Supreme Court’s interpretation of the Clean Water Act (ACOE and EPA 2008).

Item 6: Aquatic Resources Narrative
The review area contains one ephemeral drainage (Calimesa Creek). Calimesa Creek conveys water that connects to Temescal Canyon Wash approximately 7 miles downstream, which ultimately flows to the Santa Ana River. Within the review area, the drainage includes a concrete-lined trapezoidal channel containing Calimesa Creek. The downstream portion of Calimesa Creek, west of 5th Street, includes a sandy bottom earthen-lined channel that is subject to frequent scouring associated with annual storm events. While the unvegetated channel within the review area was composed primarily of bare ground and a sandy substrate, a low percent cover of plant species was observed in the review area and include sacred thorn-apple (Datura wrightii) and bromes (Bromus spp.).There are approximately 0.89 acres of ephemeral drainage within the review area identified in Figure 3 of Appendix B. This 0.89 acres of ephemeral drainage is not ACOE-jurisdictional because it is a (b)(3) non-jurisdictional waters per Title 33, Part 328.3 of the Code of Federal Regulations.

Wetland determination data forms were completed at one sampling point (WPD-1) to determine the status of three wetland criteria (vegetation, soils, and hydrology) within representative potential jurisdictional aquatic resources within the review area. Four OHWM datasheets (ODP-1 through ODP-4) were recorded at potential non-wetland waters within the review area to determine the status of OHWM indicators within those features. Wetland determination data forms and OHWM datasheets are included as Appendix C, Wetland Determination Data Forms and Ordinary High Water Mark Forms.

Totals may not sum due to rounding.

Item 10: Review Area Description
The review area is characterized as a mix of residential and commercial development, and vacant lots. One ephemeral drainage feature (Calimesa Creek) bisects the review area east to west. Based on aerial imagery (Google Earth 2019), vacant lots have been frequently disced, as recently as December 2018. This is presumed to be for weed abatement and fire prevention. Elevations range from approximately 2,380 to 2,500 feet above mean sea level. A mix of developed and undeveloped lands (i.e., vacant lots) to the north, south, east, and west surrounds the review area.

A WETS table is provided in Appendix E for the Yucaipa Station, 4.1 SE. There was climatological data available for June, July, and September 2019. However, there was no data available for August 2019 (NRCS and NWCC 2019).

Item 11: Hydrology
The review area is located within the Santa Ana Hydrologic Unit, San Timoteo Hydrologic Area, and South Mesa Hydrologic Subarea (HSA 801.67). The review area contains one ephemeral drainage (Calimesa Creek). Calimesa Creek conveys water that connects to Temescal Canyon Wash, which has surface connection ultimately flowing to the Santa Ana River (Figure 4 of Appendix B).

Item 12: Remote Sensing
No remote sensing was used for this aquatics resources delineation.

Item 13: Soils
Soil types within the project area are shown on Figure 5 of Appendix B and in Table 3. There are no hydric soils within the review area (USDA 2019).

III. SUPPORTING INFORMATION
A. Select/enter all resources that were used to aid in this determination and attach data/maps to this document and/or references/citations in the administrative record, as appropriate. ☒ Information submitted by, or on behalf of, the applicant/consultant: Calimesa Creek Stage III Project Aquatics Resources Delineation Report (Dudek 2020)
This information is sufficient for purposes of this AJD.

Rationale: N/A
☐ Data sheets prepared by the Corps: Title(s) and/or date(s). ☒ Photographs: Other: Appendix F of the Aquatics Resources Delineation Report (Dudek 2020) ☐ Corps site visit(s) conducted on: Date(s).
☐ Previous Jurisdictional Determinations (AJDs or PJDs): ORM Number(s) and date(s). ☐ Antecedent Precipitation Tool: provide detailed discussion in Section III.B. ☐ USDA NRCS Soil Survey: Title(s) and/or date(s).
☒ USFWS NWI maps: Appendix B, Figure 4 of the Aquatics Resources Delineation Report (Dudek 2020) 4 Some excluded waters, such as (b)(2) and (b)(4), may not be specifically identified on the AJD form unless a requestor specifically asks a Corps district to do so. Corps districts may, in case-by-case instances, choose to identify some or all of these waters within the review area. 5 Because of the broad nature of the (b)(1) exclusion and in an effort to collect data on specific types of waters that would be covered by the (b)(1) exclusion, four sub-categories of (b)(1) exclusions were administratively created for the purposes of the AJD Form. These four sub-categories are not new exclusions, but are simply administrative distinctions and remain (b)(1) exclusions as defined by the NWPR.

Methods
Dudek Biologist Britney Strittmater conducted a delineation of jurisdictional waters of the United States and state within the review area on September 20, 2019. Table 1 summarizes the site conditions and timing of the survey.

An aquatics resources delineation report was prepared for the review area and waters of the United States, including wetlands, that are under the jurisdiction of the U.S. Army Corps of Engineers (ACOE) are addressed in the Calimesa Creek Stage III Project Aquatics Resources Delineation Report (Dudek 2019). Maps are included in Appendix B of the Calimesa Creek Stage III Project Aquatics Resources Delineation Report (Dudek 2019), including the project location (Figure 1), U.S. Geological Survey topographic map (Figure 2), National Wetland Inventory, Hydrological Unit, and National Hydrography Data (Figure 4), and soils map (Figure 5).

Britney Strittmater no cloud cover; wind speeds from 1 to 3 mph; and temperatures ranging from 65°F to 79°F
Jurisdictional boundaries were mapped in the field using a Trimble GeoXT GPS with submeter accuracy and aerial imagery from Digital Globe dated 2018. Following the field work, Britney Strittmater digitized the resources using ArcGIS and project-specific 1-foot contour topography.

The jurisdiction-specific methods used to delineate California Department of Fish and Wildlife (CDFW) and Regional Water Quality Control Board (RWQCB) jurisdiction are described below.

CDFW Jurisdiction Methods
The delineation defined areas under the jurisdiction of the CDFW pursuant to Sections 1600–1603 of the California Fish and Game Code. A predominance of hydrophytic vegetation, where associated with a stream channel, was used to determine CDFW-regulated riparian areas. Streambeds under the jurisdiction of CDFW were delineated using the Cowardin method of waters classification, which defines waters boundaries by a single parameter (i.e., hydric soils, hydrophytic vegetation, or hydrology).

RWQCB Jurisdiction Methods
Areas regulated by the RWQCB are generally coincident with the ACOE, but can also include the adjacent riparian zone. Therefore, for this project, the RWQCB jurisdiction and CDFW jurisdiction are coincident.

Results
There are 3.1 acres of RWQCB- and CDFW-jurisdictional resources in the review area along Calimesa Creek (Table 2). Of that 3.1 acres, 2.7 acres are non-riparian streambed and 0.4 acres are riparian. Within the non-riparian areas, there is unvegetated channel and non-hydrophytic vegetation. Within the riparian areas, there is Fremont cottonwood. Figures E-1a and Figure E-1b show the CDFW-jurisdictional areas. Figures E-2a and Figure E-2b show the RWQCB-jurisdictional areas. Each vegetation community is described below.

Eucalyptus/Tree of Heaven/Black Locust Groves Semi-Natural Stands The eucalyptus/tree of heaven/black locust grove semi-natural stand is dominated by eucalyptus (Eucalyptus spp.), tree of heaven (Ailanthus altissima), or black locust (Robinia pseudoacacia) in the tree canopy, forming an open-to-continuous tree layer less than 60 meters tall with a sparse to intermittent shrub and herbaceous layer (Sawyer et al 2009).

Within the review area, this semi-natural stand occurs along the banks of Calimesa Creek within the western portion of the review area and is co-dominated by tree of heaven and black locust with a few scattered eucalyptus trees present. Scattered giant reed (Arundo donax), mule fat (Baccharis salicifolia), coast live oak (Quercus agrifolia), and Fremont cottonwood (Populus fremontii) were present, but were not dominant. This area contained a moderate amount of trash, debris, and litter resulting from homeless encampments and adjacent residential and commercial developments.

Fremont Cottonwood Forest Alliance
Fremont cottonwood forest alliance is dominated or co-dominated by Fremont cottonwood with a continuous to open tree canopy less than 25 meters tall. The shrub layer is intermittent to open and the herbaceous layer is variable (Sawyer et al. 2009). This community is found rivers, streams, lower canyons, alluvial fans, and valleys with a subsurface water supply that varies throughout the year (Sawyer et al. 2009).

coast live oaks and eucalyptus are present at lower covers. The understory is sparse and includes non-native grasses, including brome species (Bromus spp.).

Unvegetated Channel
Within the review area, unvegetated channel includes a concrete-lined trapezoidal channel containing Calimesa Creek. The downstream portion of Calimesa Creek, west of 5th Street, includes a sandy bottom earthen-lined channel that is subject to frequent scouring associated with annual storm events. While the unvegetated channel within the review area was composed primarily of bare ground and a sandy substrate, a low percent cover of plant species were observed in the review area within this land cover type include sacred thorn-apple (Datura wrightii), and bromes (Bromus spp.).

Subject: Biological Resources Letter Report and MSHCP Consistency for the Calimesa Creek Stage III Project, City of Calimesa, Riverside County, California Dear Mr. Ledbetter:

This biological resources habitat assessment and Western Riverside County Multiple Species Habitat Conservation Plan (MSHCP) consistency analysis letter report describes the existing biological conditions of the proposed Calimesa Creek Stage III Project (project) site. The proposed project is analyzed in the context of the California Environmental Quality Act (CEQA) and the MSHCP. This report is intended to describe the existing conditions of the project site and the existing conditions within 500 feet of the project site where access was granted, which is referred to in this report as the study area. This report also describes the general biological reconnaissance survey methods and results, special-status biological resources present or potentially present on site, and potential constraints to development that may be posed by biological resources on the project site. This report also provides an MSHCP consistency assessment including the following requirements of the MSHCP (relevant MSHCP sections are identified in parentheses):
 Riparian/riverine, vernal pool, and fairy shrimp requirements (Section 6.1.2)  Urban/wildlife interface guidelines (Section 6.1.4)
The proposed project design is in the process of being finalized; therefore, this report does not analyze potential impacts to special-status biological resources in the context of CEQA or the MSHCP. An impacts analysis will be added to this report once the project design has been finalized. 1 Introduction

1.1 Project Location and Description
The 18.5-acre project site is located south of County Line Road, east of Interstate 10 (I-10) and west of 3rd Street, in the City of Calimesa in Riverside County (Figure 1, Project Location; figures can be found in Attachment A, Figures). The project site occurs within U.S. Geological Survey (USGS) 7.5-minute Yucaipa quadrangle map, Sections 11, 12, 13, and 14 of Township 2 South, Range 2 West. The approximate center of the property is at longitude 117°03ʹ19.83″W and latitude 33°00ʹ11.94″N.

The proposed project is considered a continuation of the Calimesa Channel “Stage I” and Stage II” projects completed by the Riverside County Flood Control and Water Conservation District. The proposed project is a component of a storm drain system that will provide 100-year flood protection to existing developments along Mr. Steve Ledbetter

County Line Road and would consist of a detention basin and a storm drain system for the Calimesa Channel watershed upstream from the existing storm drain system at I-10 Freeway. The proposed project will provide the following benefits: (1) reduce peak 100-year flow rate to downstream facilities; (2) reduce storm drain infrastructure cost; (3) eliminate flooding at Park Avenue and Calimesa Boulevard; (4) alleviate flooding along the County Line Road and I-10 Freeway underpass; and (5) provide flood protection for the Fire Station, City Hall, and City of Calimesa proposed Downtown Business District.

1.2 Applicable Regulations
This section outlines the federal, state, and local regulations pertinent to the biological resources located in the proposed project area.

1.2.1 Federal
Federal Endangered Species Act
The federal Endangered Species Act (FESA) of 1973 (16 USC 1531 et seq.), as amended, is administered by the U.S. Fish and Wildlife Service (USFWS), the National Oceanic and Atmospheric Administration, and National Marine Fisheries Service. This legislation is intended to provide a means to conserve the ecosystems upon which endangered and threatened species depend, and to provide programs for the conservation of those species, thus preventing extinction of plants and wildlife. Under provisions of FESA Section 9(a)(1)(B), it is unlawful to “take” any listed species. “Take” is defined in FESA Section 3(19) as, “harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect, or to attempt to engage in any such conduct.” Migratory Bird Treaty Act
The Migratory Bird Treaty Act prohibits the take of any migratory bird or any part, nest, or eggs of any such bird. In 2017, the Department of Interior Deputy Solicitor’s Opinion M-37050 stated that the Migratory Bird Treaty Act applies to “affirmative actions” that have “take” as their purpose. Projects may not “take” migratory birds if the action’s intent is to take or kill a migratory bird. Under the Migratory Bird Treaty Act, “take” is defined as pursuing, hunting, shooting, capturing, collecting, or killing, or attempting to do so (16 USC 703 et seq.). Additionally, Executive Order 13186, “Responsibilities of Federal Agencies to Protect Migratory Birds,” requires that any project with federal involvement address impacts of federal actions on migratory birds with the purpose of promoting conservation of migratory bird populations (66 FR 3853–3856). Nests are considered “active” if they currently support viable eggs, chicks, or young that are dependent on the nest and have not been abandoned by the parents.

1.2.2 State
California Endangered Species Act
The California Department of Fish and Wildlife (CDFW) administers the California Endangered Species Act (CESA) (California Fish and Game Code, Section 2050 et seq.), which prohibits the “take” of plant and animal species designated by the Fish and Game Commission as endangered or threatened in the State of California. Under CESA Section 86, “take” is defined as “hunt, pursue, catch, capture, or kill, or attempt to hunt, pursue, catch, capture, or kill.” CESA Section 2053 stipulates that state agencies may not approve projects that will “jeopardize the continued Mr. Steve Ledbetter
Subject: Biological Resources Letter Report and MSHCP Consistency for the Calimesa Creek Stage III, City of Calimesa, Riverside County, California
12200
3 October 2019
existence of any endangered species or threatened species or result in the destruction or adverse modification of habitat essential to the continued existence of those species, if there are reasonable and prudent alternatives available consistent with conserving the species or its habitat which would prevent jeopardy.” CESA Sections 2080 through 2085 address the taking of threatened, endangered, or candidate species by stating, “No person shall import into this state, export out of this state, or take, possess, purchase, or sell within this state, any species, or any part or product thereof, that the Commission determines to be an endangered species or a threatened species, or attempt any of those acts, except as otherwise provided in this chapter, the Native Plant Protection Act (Fish and Game Code, Sections 1900–1913), or the California Desert Native Plants Act (Food and Agricultural Code, Section 80001).”
Fish and Game Code Section 2081(b) and (c) authorizes take of endangered, threatened, or candidate species if take is incidental to otherwise lawful activity and if specific criteria are met. These provisions also require CDFW to coordinate consultations with USFWS for actions involving federally listed species that are also state-listed species.

In certain circumstances, CESA Section 2080.1 allows CDFW to adopt a federal incidental take statement, or a 10(a) permit as its own, based on its findings that the federal permit adequately protects the species and is consistent with state law. A Section 2081(b) permit may not authorize the take of “fully protected” species and “specified birds” (California Fish and Game Code, Sections 3505, 3511, 4700, 5050, 5515, and 5517). If a project is planned in an area where a fully protected species or a specified bird occurs, an applicant must design the project to avoid take.

Fish and Game Code
Pursuant to Fish and Game Code Section 3503.5, it is unlawful to take, possess, or destroy any birds of prey; or to take, possess, or destroy any nest or eggs of such birds. Birds of prey refer to species in the orders Falconiformes and Strigiformes. Nests of all other birds (except English sparrow [house sparrow; Passer domesticus] and European starling [Sturnus vulgaris]) are protected under Fish and Game Code Sections 3503 and 3513.

According to Fish and Game Code Sections 3511 and 4700, which regulate birds and mammals, respectively, a “fully protected” species may not be taken or possessed without a permit from the Fish and Game Commission, and “incidental takes” of these species are not authorized.

1.2.3 Local
City of Calimesa Municipal Code
Chapter 18.80, Tree Preservation, of the City of Calimesa Municipal Code, sets forth the policy of the City to regulate the cutting, pruning, removal, relocation, or replacement of oak trees unless reasonable and conforming use of the property justifies the removal, cutting, pruning, and/or encroachment into the protected zone of an oak tree, heritage tree, or protected stand of oak trees.

3 Methods
For this biological resources letter report, “special-status” species are those that are (1) listed, proposed for listing, or candidates for listing as threatened or endangered under FESA; (2) listed or candidates for listing as threatened or endangered under CESA; (3) a state fully protected species; (4) a CDFW Species of Special Concern; (5) a species listed on the California Native Plant Society’s Inventory of Rare and Endangered Plants with a California Rare Plant Rank of 1B or 2B; or (6) an MSHCP covered species not adequately conserved and species for which the MSHCP has additional surveys requirements for the project site. Special-status vegetation communities are those identified as high priority for inventory in the Natural Communities List (CDFW 2018) by a state rarity ranking of S1, S2, or S3 or identified as a protected resource by the City’s Municipal Code.

3.1 Literature Review
Special-status biological resources present or potentially present on the study area were identified through a literature search using the following sources: USFWS’s Critical Habitat and Occurrence Data (USFWS 2019a); CDFW’s California Natural Diversity Database (CDFW 2019b); the California Native Plant Society’s online Inventory of Rare and Endangered Plants (CNPS 2019); the Calflora database, which compiles observation and plant data from both private and public institutions, including the Consortium of California herbaria (Calflora 2019); a Natural Resources Conservation Service soil map (USDA 2019a); the USGS 7.5-minute topographic quadrangle (USGS 2019); U.S. Environmental Protection Agency Watershed Assessment, Tracking & Environmental Results System (EPA 2019), which includes the National Hydrography Dataset; and the National Wetland Inventory (USFWS 2019b).

Searches were completed for the following USGSy quadrangles (which include the quadrangle within which the study area is located and the eight surrounding quadrangles): Harrison Mountain, Keller Peak, Big Bear Lake, Redlands, Yucaipa, Forest Falls, Sunnymead, El Casco, and Beaumont.

Additionally, previous reports prepared for the study area were reviewed including the Draft Biological Resources Letter Report (CALIFAUNA 2013) and Biological Field Report/Follow-Up (Froke 2016).

3.2 Field Reconnaissance
Dudek Biologist Britney Strittmater conducted a general biological survey of the study area on September 20, 2019, from 9:45 a.m. to 2:45 p.m. Private properties within the study area were surveyed visually with binoculars from the project site boundary or public roads. The survey was conducted when weather conditions were favorable, with no cloud cover, wind speeds from 1 to 3 miles per hour, and temperatures ranging from 65°F to 79°F. All native and naturalized plant species encountered within the study area were identified and recorded. The potential for special-status plant and wildlife species to occur within the study area was evaluated based on the vegetation communities, soils present, and surrounding features. Vegetation communities and land covers on site were mapped directly in the field onto a 200-foot-scale (1 foot = 200 feet) aerial photograph-based field map of the study area. A formal jurisdictional delineation was conducted on September 20, 2019. The methodology and results are provided under a separate cover; therefore, they are not further discussed within this report.

Rank, Latin names follow the Jepson Interchange List of Currently Accepted Names of Native and Naturalized Plants of California (Jepson Flora Project 2019), and common names follow the U.S. Department of Agriculture’s Natural Resources Conservation Service Plants Database (USDA 2019b). Natural vegetation communities were mapped in the field using the Vegetation Alliances of Western Riverside County (Klein and Evens 2006). Land cover types (i.e., areas that lack vegetation communities) were described in accordance with Draft Vegetation Communities of San Diego County (Oberbauer et al. 2008). Latin and common names of animals follow Crother (2012) for reptiles and amphibians, the American Ornithologists’ Union (AOU 2018) for birds, Wilson and Reeder (2005) for mammals, the North American Butterfly Association (NABA 2016) for butterflies, and Moyle (2002) for fish.

Geographic information system (GIS) analysts digitized the mapped biological resources from field maps to create the baseline biological conditions.

3.3 Survey Limitations
Access was not available within the 500-foot buffer from the project site because some of the properties are private and access was not granted. The 500-buffer was surveyed visually using binoculars. Therefore, vegetation mapping and habitat assessments were conducted from the project site or other public roads, in addition to being complimented with the use of aerial signatures of vegetation communities occurring within the study area.

The reconnaissance survey was conducted during the late summer/early fall season, which resulted in detection and identification of most perennial plant species that may potentially occur in the area. Due to the timing of the surveys, spring and summer annual and cryptic perennials may not have been detectable. Conditions were suitable for detection of most wildlife species (i.e., no cloud cover, 65°F–79°F temperatures, and light winds). However, timing of the survey limited the observations of neotropical breeding birds. 4 Results

4.1 Site Description
The study area is characterized as a mix of residential and commercial development, and vacant lots. The majority of the study area has been developed for over 50 years and the non-developed areas have been substantially disturbed by mowing and tilling (Google Earth 2019; NETRonline 2019). Based on aerial imagery (Google Earth 2019), vacant lots have been frequently disced, as recently as December 2018. This is presumed to be for weed abatement and fire prevention. One ephemeral drainage feature (Calimesa Creek) bisects the study area east to west. Elevations range from approximately 2,380 to 2,500 feet above mean sea level. A mix of developed and undeveloped lands (i.e., vacant lots) to the north, south, east, and west surrounds the study area. Representative photographs of the project site are included in Attachment B, Site Photographs.

4.2 Soils
Four soil types are mapped within the study area: Ramona sandy loam (2% to 5% slopes; eroded); Ramona sandy loam (2% to 9% slopes); Ramona very fine sandy loam (0% to 8% slopes; eroded), and San Timoteo (25% to 50% slopes; eroded) (USDA 2019a). The spatial distribution of these soils is depicted in Figure 2, Soils.  Ramona Series consists of well-drained soils formed in alluvium derived mostly from granitic and related rock sources. These soils typically occur on terraces and fans (USDA 2019b). This soil series occurs in the northern, eastern, and southern portions of the study area.  San Timoteo Series consists of moderately deep, well to somewhat excessively drained soils formed in material weathered from shale, sandstone, and calcified weathered granite. These soils typically occur on upland slopes (USDA 2019b). This soil series occurs in the western portion of the study area in between the Ramona Series.

4.3 Vegetation Communities and Land Covers
Two vegetation communities and three non-natural land cover types were documented within the study area:
eucalyptus/tree of heaven/black locust groves, Fremont cottonwood, disturbed habitat, non-vegetated channel or floodway, and urban/developed. Figure 3, Biological Resources, illustrates the distribution of vegetation communities and land covers, and Table 1 provides a summary of each vegetation community and land cover’s extent within the study area.

4.3.1 Eucalyptus/Tree of Heaven/Black Locust Groves Semi-Natural Stands The eucalyptus/tree of heaven/black locust grove semi-natural stand is dominated by eucalyptus (Eucalyptus spp.), tree of heaven (Ailanthus altissima), or black locust (Robinia pseudoacacia) in the tree canopy, forming an open-to-continuous tree layer less than 60 meters tall with a sparse to intermittent shrub and herbaceous layer (Sawyer et al 2009).

7 October 2019
Within the study area, this semi-natural stand occurs along the banks of Calimesa Creek within the western portion of the study area and is co-dominated by tree of heaven and black locust with a few scattered eucalyptus trees present. Scattered giant reed (Arundo donax), mulefat (Baccharis salicifolia), coast live oak (Quercus agrifolia), and Fremont cottonwood (Populus fremontii) were present, but did not create a continuous canopy or high enough cover to warrant their own community. This community contained a moderate amount of trash, debris, and litter resulting from homeless encampments and adjacent residential and commercial developments.

The eucalyptus/tree of heaven/black locust grove semi-natural stand does not have a rank in CDFW (2018); therefore, this semi-natural stand is not considered special status under CEQA.

4.3.2 Fremont Cottonwood Forest Association
Fremont cottonwood forest association is dominated or co-dominated by Fremont cottonwood with a continuous to open tree canopy less than 25 meters tall. The shrub layer is intermittent to open, and the herbaceous layer is variable (Sawyer et al. 2009). This community is found rivers, streams, lower canyons, alluvial fans and valleys with a subsurface water supply that various throughout the year (Sawyer et al. 2009).

Fremont cottonwood forest occurs along the downstream banks of Calimesa Creek within the western portion of the study area. This vegetation community contains greater than 5% absolute cover of Fremont cottonwood warranting a community; however, this community does include a high cover of tree of heaven. Scattered emergent coast live oaks and eucalyptus are present at lower covers. The understory is sparse and includes non-native grasses including brome species (Bromus spp.).

The Fremont cottonwood forest alliance is ranked by CDFW (2018) as a G3S3 alliance. This ranking indicates that globally and within California the alliance is considered vulnerable and at moderate risk (and is also considered rare and of high priority); therefore, it is considered special status under CEQA. All Fremont cottonwood associations are listed as a high priority for inventory (CDFW 2018) and are considered special status under CEQA.

4.3.3 Disturbed Habitat
The classification of disturbed habitat is due to the predominance of bare ground, non-native plant species, and other disturbance-tolerant plant species. Oberbauer et al. (2008) describes disturbed habitat as areas that have been physically disturbed by previous human activity and are no longer recognizable as a native or naturalized vegetation association, but that continue to retain a soil substrate. Typically, vegetation, if present, is nearly exclusively composed of non-native annual plant species.

Within the study area, disturbed land includes vacant lots that contain a mix of non-native and ruderal species including dove weed (Croton setiger), prickly Russian thistle (Salsola tragus), and common sunflower (Helianthus annuus).

Disturbed habitat is not recognized by CDFW (2018); therefore, this non-natural land cover is not considered special status under CEQA.

4.3.4 Non-Vegetated Floodplain or Channel
Oberbauer et al. (2008) describes non-vegetated floodplain or channel as waterways or flood channels that are unvegetated on a relatively permanent basis that contain sandy, gravelly, or rocky substrates. Vegetation may be present, but is typically less than 10% total cover (Oberbauer et al. 2008).

Within the study area, non-vegetated floodplain or channel encompasses Calimesa Creek. The upstream portion of Calimesa Creek, east of 5th Street, includes a concrete-lined trapezoidal channel. The downstream portion of Calimesa Creek, west of 5th Street, includes a sandy bottom earthen-lined channel that is subject to frequent scouring associated with annual storm events. While the non-vegetated floodplain or channel within the study area was composed primarily of bare ground and a sandy substrate, a low cover of plant species observed in the study area within this land cover type include sacred thorn-apple (Datura wrightii), and bromes.

Non-vegetated floodplain or channel is not recognized by CDFW (2018); however, non-vegetated floodplain or channel may be jurisdictional by the U.S. Army Corps of Engineers pursuant to Section 404 of the Clean Water Act, Regional Water Quality Control Board pursuant to Section 401 of the Clean Water Act or Porter Cologne Act, CDFW pursuant to Section 1602 of the California Fish and Game Code, or considered a special-status resource under the MSHCP. Thus, non-vegetated floodplain or channel may be afforded protection under CEQA.

4.3.5 Urban/Developed
Urban/developed is defined by Oberbauer et al. (2008) as areas that have been constructed on or disturbed so severely that native vegetation is no longer supported. Urban/developed lands includes areas with permanent or semi-permanent structures, pavement or hardscape, landscaped areas, and areas with a large amount of debris or other materials.

Urban/developed land takes the form of residential and commercial development with landscaped ornamentals present, and paved roads.

Urban/Developed is not recognized by CDFW (2018); therefore, this non-natural land cover is not considered special status under CEQA.

4.4 Floral Diversity
A total of 34 species of native or naturalized plants, 13 native (38%) and 21 non-native (62%), were recorded within the study area. This relatively low plant diversity reflects the study area location in an urbanized area and the timing of the site visit, which was conducted in late summer/early fall, which would have precluded the detection of spring and summer blooming annuals. In addition, a majority of the study area was surveyed from public roads, which inherently constrains the ability to inventory all plant species. Plant species observed within the study area are listed in Attachment C, Vascular Plant Species.

4.5 Wildlife
A total of five bird species were detected within the study area, including house finch (Haemorhous mexicanus), California scrub-jay (Aphelocoma californica), American crow (Corvus brachyrhynchos), northern mockingbird (Mimus polyglottos), and mourning dove (Zenaida macroura). No active bird nests were observed within the study area during the reconnaissance survey; however, the ornamental vegetation and native vegetation (i.e., Fremont cottonwood forest) within the study area provides habitat for nesting birds and raptors. No amphibian species were observed, and no amphibian species are expected to occur. One reptile species was observed during the survey:
common side-blotched lizard (Uta stansburiana). Three mammal species were detected during the survey:

California ground squirrel (Spermophilus (Otospermophilus) beecheyi), desert cottontail (Sylvilagus audubonii), and domestic dog (Canis lupus familiaris). Wildlife species observed within the study area are listed in Attachment D, Wildlife Species.

4.6 Special-Status Plant Species
Attachment E, Special-Status Plant Species Detected or Potentially Occurring in the Study Area, lists special-status plant species that have been documented in the USGS 7.5-minute Yucaipa quadrangle and the eight surrounding quadrangles (CDFW 2019; CNPS 2019). For each species listed, a determination was made regarding the potential for the species to occur in the study area based on information gathered during the field reconnaissance, including the location of the site, habitats present, current site conditions, and past and present land use. Listed species with a potential to occur and non-listed special-status species with a moderate or higher potential to occur are discussed herein.

Focused special-status plant surveys were not conducted. No federally or state listed special-status plant species were incidentally detected within the study area. One non-listed special-status species, southern California black walnut (Juglans californica), which has a California Rare Plant Rank of 1B.1, was observed within the study area along the banks of Calimesa Creek; however, this species is a covered species under the MSHCP (County of Riverside 2003). No federally or state listed or other special-status species have a moderate or high potential to occur within the study area (Attachment E).

4.7 Special-Status Wildlife Species
Attachment F, Special-Status Wildlife Species Detected or Potentially Occurring in the Study Area, lists special-status wildlife species that have been documented in the USGS 7.5-minute Yucaipa quadrangle and the eight surrounding quadrangles (CDFW 2019). For each special-status wildlife species, a determination was made regarding potential use of the study area based on information gathered during the field reconnaissance, known habitat preferences, and knowledge of the species’ relative distributions in the area. There are no federally or state listed wildlife species and other special-status wildlife species with a moderate or higher potential to occur in the study area.

Thirteen special-status wildlife species have a low potential to occur within the study area (Attachment F), including the state fully protected white-tailed kite (Elanus leucurus). White-tailed kite has a low potential to nest and forage within the study area, and this species is covered under the MSCHP.

4.8 Nesting Birds
The reconnaissance survey was conducted outside of nesting season; however, the study area provides potential nesting habitat for commonly occurring birds such as Anna’s hummingbird (Calypte anna) or house finch. The study area does contain large trees (e.g., eucalyptus, tree of heaven, black locust, coast live oak) suitable for raptor nesting.

4.9 Wildlife Corridors and Habitat Linkages
Wildlife corridors are linear features that connect large patches of natural open space and provide avenues for the migration of animals. Habitat linkages are small patches that join larger blocks of habitat and help reduce the adverse effects of habitat fragmentation; they may be continuous habitat or discrete habitat islands that function as stepping stones for wildlife dispersal. The study area is not within any designated wildlife corridors and/or habitat linkages identified in the South Coast Missing Linkages analysis project (South Coast Wildlands 2008), California Essential Habitat Connectivity project (Spencer et al. 2010), or as recognized by the MSHCP. The study area is isolated from designated wildlife corridors/habitat linkages and other open spaces by substantial developed areas and heavily traversed roadways, including I-10. Waters from Calimesa Creek flow into San Timoteo Creek, but Calimesa Creek is an ephemeral drainage, with a relatively small watershed (890 acres) that is highly developed, so native fish species are not expected to be present or use the creek within the study area for upstream or downstream movement.

On a local level, the study area is dominated by developed areas that support minimal vegetation (particularly native vegetation). Calimesa Creek bisects the study area; however, the natural portions of the creek west of I-10 are primarily limited to the study area. Waters from Calimesa Creek flow downstream from the study area into underground culverts beneath Calimesa Boulevard and then for approximately 500 feet beneath I-10 (Google Earth 2019). Calimesa Creek is within a concrete channel in the eastern portion of the study, and its waters are conveyed through underground culverts approximately 0.5 miles to the east of the study area (Google Earth 2019). The study area may provide local movement for some urban-adapted wildlife species (i.e., coyote, striped skunk, raccoon, opossum), but these species would be expected to be able to use similar urban habitat that is adjacent to the study area.
5 Western Riverside County MSHCP Consistency Analysis
The study area is located in the MSHCP Pass Area Plan and must comply with relevant sections of the MSHCP. The study area is not within an MSHCP Criteria Cell (Figure 4, Western Riverside MSHCP Plan Area); therefore, no Reserve Assembly requirements would apply to the project. The study area is not located within MSCHP Section

6.1.3 Narrow Endemic Species Survey Area or MSHCP Section 6.3.2 Additional Survey Needs and Procedures for Criteria Area Plant Species, Burrowing Owl, Mammals, or Amphibians; therefore, additional survey requirements for these biological resources would not apply to the project and are not further discussed. The project’s compliance with the relevant sections of the MSHCP is discussed below.

11 October 2019

5.1 MSHCP Section 6.1.2 Riparian/Riverine Resources
The MSHCP defines riparian/riverine areas as “lands which contain habitat dominated by trees, shrubs, persistent emergent, or emergent mosses and lichens, which occur close to or which depend upon soil moisture from a nearby fresh water source; or areas with fresh water flow during all or a portion of the year.” The MSHCP further clarifies those areas “demonstrating characteristics as described above which are artificially created are not included in these definitions” (County of Riverside 2003).

There are approximately 3.31 acres of MSHCP riparian/resources within the study area, specifically 2.94 acres of riverine resources and 0.37 acres of riparian habitat (Figure 5, Western Riverside MSHCP Biological Resources).

The study area contains one ephemeral drainage (Calimesa Creek) and associated riparian vegetation (Fremont cottonwood forest). Calimesa Creek conveys water ultimately connecting to Temescal Canyon Wash, which has surface connection ultimately flowing to the Santa Ana River. Because this feature conveys water to downstream resources, Calimesa Creek would be considered riverine resources as defined by the MSHCP. Additionally, the associated Fremont cottonwood forest would be considered a riparian resource as defined by the MSHCP.

5.1.1 Vernal Pools and Fairy Shrimp Habitat
The MSHCP defines vernal pools as the following (County of Riverside 2003):
[S]easonal wetlands that occur in depression areas that have wetlands indicators of all three parameters (soils, vegetation and hydrology) during the wetter portion of the growing season but normally lack wetlands indicators of hydrology and/or vegetation during the drier portion of the growing season. Obligate hydrophytes and facultative wetlands plant species are normally dominant during the wetter portion of the growing season, while upland species (annuals) may be dominant during the drier portion of the growing season. The determination that an area exhibits vernal pool characteristics, and the definition of the watershed supporting vernal pool hydrology, must be made on a case-by-case basis. Such determinations should consider the length of the time the area exhibits upland and wetland characteristics and the manner in which the area fits into the overall ecological system as a wetland. Evidence concerning the persistence of an area's wetness can be obtained from its history, vegetation, soils, and drainage characteristics, uses to which it has been subjected, and weather and hydrologic records.

Fairy shrimp habitat also includes ephemeral pools and other features such as road ruts or stock ponds.

No vernal pool–indicator plant species were identified within the area, and no vernal pools were observed within the study area. Soils mapped in the region are Ramona sandy loam, Ramona very fine sandy loam, and San Timoteo soils.

These series are all considered well to moderately well draining and therefore are not known to retain ponded water.

However, based on historic aerial imagery (Google Earth 2019), a topographic low point southwest of the intersection of 3rd Street and County Line Road contained standing water as recently as December 2018. This area is consists of a dirt vacant lot that has been graded and lacks vegetation. This topographic low point has contained standing water over the years with standing water also observed in February 2016 and April 2014 (Google Earth 2019). Therefore, based on the fact that this area does hold water, this area was determined to potentially support habitat for Riverside fairy shrimp (Streptocephalus woottoni) (Figure 5, Western Riverside MSHCP Biological Resources).

5.1.2 Riparian Birds
The study area supports a few scattered individuals of mulefat, Fremont cottonwood, and giant reed along the central portion of Calimesa Creek as observed during the September 2019 field visit. These scattered individuals are not considered a riparian resource as defined by the MSHCP as they did not create a continuous canopy or high enough cover to warrant their own community. The study area also supports Fremont cottonwood forest at the downstream portion of Calimesa Creek, and this community is considered a riparian resource as defined by the MSHCP. This riparian vegetation is narrow and small in its extent, lacks understory or closed-canopy features, lacks continuity with higher quality habitat, and is not contiguous; therefore, it is not sufficient to support riparian bird species such as least Bell’s vireo (Vireo bellii pusillus), southwestern willow flycatcher (Empidonax traillii extimus), or yellow-billed cuckoo (Coccyzus americanus).

5.2 MSHCP Section 6.1.4 Urban/Wildlife Interface Guidelines According to the MSHCP, the Urban/Wildlands Interface Guidelines are intended to address indirect effects associated with locating development in proximity to the MSHCP Conservation Area (County of Riverside 2003, pp. 6–42). The study area is not within any conserved areas; however, Calimesa Creek flows to San Timoteo Creek, which ultimately flows to the Santa Ana River. Due to the proposed project having connectivity to areas described for conservation, the Urban/Wildlife Interface Guidelines are applicable. 6 Conclusions
The study area includes the following special-status biological resources: southern California black walnut, coast live oak, MSHCP riparian/riverine habitat, and potential fairy shrimp habitat. If these resources are impacted as a result of project implementation, avoidance, minimization, and mitigation measures are recommended for the project to be consistent with the MSHCP and that would result in less-than-significant impacts to biological resources under CEQA.

California black walnut is a covered species under the MSHCP; therefore, compliance with the MSHCP as well as payment of the applicable MSHCP Development Mitigation Fee offsets potential direct and indirect impacts to this species. Coast live oaks are a protected resource under the City of Calimesa Municipal Code; therefore, impacts to this species would require appropriate mitigation to offset potential direct and indirect impacts to this species.

Impacts to MSHCP Section 6.1.2 Riparian/Riverine resources would require preparation of a Determination of Biologically Equivalent or Superior Preservation identifying avoidance, minimization, and mitigation measures for impacts to riparian and riverine resources. If the proposed project would result in impacts to potential fairy shrimp habitat, two seasons of fairy shrimp surveys would be required. If the proposed project cannot avoid at least 90% of the long-term conservation value of the habitat, a Determination of Biologically Equivalent or Superior Preservation Report would be required.

The results of the formal jurisdictional delineation are provided under a separate cover; however, the proposed project would result in potential impacts to non-wetland waters of the United States and streambeds under the jurisdiction of the U.S. Army Corps of Engineers, Regional Water Quality Control Board, and CDFW. Therefore, the proposed project is expected to require a permit pursuant to Section 404 of the Clean Water Act from the U.S. Army Mr. Steve Ledbetter
