1 I. Introduction and Setting
A. Purpose and Objectives
The purpose of this report is to provide an assessment of the noise and vibration impacts that may occur with the development of the proposed car dealership and to identify mitigation measures that may be necessary to reduce those impacts. The objectives of the study include:
 documentation of existing noise conditions
 discussion of noise modeling methodology and procedures  analysis of noise and vibration generated by the construction of the project  analysis and discussion of potential traffic noise impacts to the proposed project  analysis of noise affecting nearby sensitive receptors due to increased traffic produced by the project
 recommendations for mitigation measures
B. Project Location
The project site is located at 1155 Graves Avenue in the City of El Cajon. The vicinity map showing the project location is provided on Figure 1.

C. Proposed Project
The 1.6-acre project site is proposed to be developed with a Hyundai dealership. The proposed 36,989 square foot building will include a showroom, offices, a parts department, a service department, a service drive, and an express lube. Express lube doors will be used for vehicle access but will be kept closed. No impact equipment or air compressors will be utilized in the express lube area. A car wash is proposed in a separate building. Figure 2 illustrates the project site plan. The proposed site plan is shown in Figure 2.

D. Sensitive Noise Receptors
The State of California defines sensitive receptors as those land uses that require serenity or are otherwise adversely affected by noise events or conditions. Schools, libraries, churches, hospitals, single and multiple-family residential, including transient lodging, motels and hotel uses make up the majority of these areas. The nearest sensitive receptors to the project site are single-family residential properties located to the north and east of the project site.

4 II. Noise and Vibration Fundamentals

A. Sound and Noise

Sound can be described as the mechanical energy of a vibrating object transmitted by pressure waves through a liquid or gaseous medium (e.g., air) to a hearing organ, such as a human ear.

Noise is defined as loud, unexpected, or annoying sound. Common noise sources and their associated noise levels are shown in Figure 3.

In the science of acoustics, the fundamental model consists of a sound (or noise) source, a receiver, and the propagation path between the two. The loudness of the noise source and the obstructions or atmospheric factors affecting the propagation path to the receiver determines the sound level and characteristics of the noise perceived by the receiver. The field of acoustics deals primarily with the propagation and control of sound, with associated factors summarized below.

Frequency
Continuous sound can be described by frequency (pitch) and amplitude (loudness), with a low- frequency sound perceived as low in pitch. Frequency is expressed in terms of cycles per second, or Hertz (Hz). A frequency of 250 cycles per second, for example, is referred to as 250 Hz), with higher frequencies sometimes more conveniently expressed in kilohertz (kHz), or thousands of Hz.

The audible frequency range for humans is generally between 20 and 20,000 Hz (or 20 kHz).

Sound Pressure Levels and Decibels
The amplitude of pressure waves generated by a sound source determines the loudness of that source. Sound pressure amplitude is measured in micro-Pascals (mPa), with one mPa representing approximately one hundred billionth of normal atmospheric pressure. Sound pressure amplitudes for different kinds of noise environments can range from less than 100 to 100,000,000 mPa.

Because of this huge range of values, sound is rarely expressed in terms of mPa. Instead, a logarithmic scale is used to describe sound pressure level (SPL) in terms of decibels (dB). The threshold of audible sound is about 0 dB for a healthy human ear, which corresponds to 20 mPa.

Sound Propagation
When sound propagates over a distance, it changes in level and frequency content. Sound from a localized source (i.e., a point source) propagates uniformly outward in a spherical pattern. The sound level attenuates (or decreases) at a rate of six dB for each doubling of distance from a point source. Sound levels from a line source attenuate at a rate of three dB for each doubling of distance.

A large object or barrier in the path between a noise source and a receiver can substantially attenuate noise levels at the receiver. The amount of attenuation provided by shielding depends on the size of the object and the frequency content of the noise source. Natural terrain features (e.g., hills and dense/deep woods) and human-made features (e.g., buildings and walls) can substantially reduce noise levels. Walls are often constructed between a source and a receiver specifically to reduce noise. A barrier that breaks the line of sight between a source and a receiver

6 will typically result in at least five dB of noise reduction, with taller barriers providing increased noise reduction. Vegetation, such as highway landscaping, between the source and receiver is rarely effective in reducing noise, as it does not create a solid barrier.

Human Perception of Noise
The decibel scale alone does not adequately characterize how humans perceive noise, as the dominant frequencies of a sound have a substantial effect on the human response to that sound.

Although the intensity (energy per unit area) of the sound is a purely physical quantity, the loudness or human response is determined by the characteristics of the human ear. Human hearing is limited in the range of audible frequencies, as well as in the way it perceives the SPL within that range. In general, people are most sensitive to the frequency range of 1,000 to 8,000 Hz and perceive sounds within that range better than sounds of the same amplitude in higher or lower frequencies. To approximate the response of the human ear, sound levels of individual frequency bands are weighted, depending on the human sensitivity to those frequencies. An “A- weighted” sound level (expressed in units of dBA) can then be calculated from this information.

Noise levels are typically reported in terms of A-weighted decibels or dBA. Table 1, Typical A- weighted Noise Levels, describes levels for various noise sources.

B. Noise Descriptors

Noise in the daily human environment fluctuates over time; these changes can be minor or substantial, depending on individual factors. Specifically, noise fluctuations can be influenced by conditions such as: (1) whether noise levels occur in regular or random patterns; (2) if noise level fluctuations are rapid or slow; and (3) if noise levels vary widely or are relatively constant. Various noise descriptors have been developed to describe time-varying noise levels, with the following noise descriptors most commonly used in transportation noise analysis.

Equivalent Sound Level (Leq)
Leq represents an average of the sound energy occurring over a specified period. In effect, Leq is the steady-state sound level containing the same acoustical energy as the time-varying sound that actually occurs during the same period. The one-hour A-weighted equivalent sound level (Leq[h]), for example, is the energy average of A-weighted sound levels occurring during a one-hour period. One hour is the normal (default) assumed time period for Leq unless stated otherwise.

Percentile-Exceeded Sound Level (LXX)
LXX represents the sound level exceeded for a given percentage of a specified period. For example, L10 is the sound level exceeded 10 percent of the time, and L90 is the sound level exceeded 90 percent of the time.

Maximum Sound Level (Lmax)
Lmax is the maximum sound level measured during a specified time period with “slow/1-second” time-averaging.

7 Day-Night Level (Ldn)
Ldn is the energy average of A-weighted sound levels occurring over a 24-hour period, with a 10- dB penalty applied to A-weighted sound levels occurring during nighttime hours between 10 PM and 7 AM

Community Noise Equivalent Level (CNEL)
Similar to Ldn, CNEL is the energy average of the A-weighted sound levels occurring over a 24- hour period, with a 10-dB penalty applied to A-weighted sound levels occurring during the nighttime hours between 10 PM and 7 AM, and a 5-dB penalty applied to the A-weighted sound levels occurring during evening hours between 7 PM and 10 PM.

8 C. Vibration Fundamentals

The way in which vibration is transmitted through the earth is called propagation. Propagation of earthborn vibrations is complicated and difficult to predict because of the endless variations in the soil through which waves travel. There are three main types of vibration propagation: surface, compression, and shear waves. Surface waves, or Raleigh waves, travel along the ground’s surface. These waves carry most of their energy along an expanding circular wave front, similar to ripples produced by throwing a rock into a pool of water. Compression waves, or P-waves, are body waves that carry their energy along an expanding spherical wave front. The particle motion in these waves is longitudinal (i.e., in a “push-pull” fashion). P-waves are analogous to airborne sound waves. Shear waves, or S-waves, are also body waves that carry energy along an expanding spherical wave front. However, unlike P-waves, the particle motion is transverse or “side-to-side and perpendicular to the direction of propagation”.

As vibration waves propagate from a source, the energy is spread over an ever-increasing area such that the energy level striking a given point is reduced with the distance from the energy source. This geometric spreading loss is inversely proportional to the square of the distance.

Wave energy is also reduced with distance as a result of material damping in the form of internal friction, soil layering, and void spaces. The amount of attenuation provided by material damping varies with soil type and condition as well as the frequency of the wave.

Vibration amplitudes are usually expressed as either peak particle velocity (PPV) or the root mean square (RMS) velocity. The PPV is defined as the maximum instantaneous peak of the vibration signal in inches per second. The RMS of a signal is the average of the squared amplitude of the signal in vibration decibels (VdB), ref one micro-inch per second. The Federal Railroad Administration uses the abbreviation “VdB” for vibration decibels to reduce the potential for confusion with sound decibel.

PPV is appropriate for evaluating the potential of building damage and VdB is commonly used to evaluate human response. Decibel notation acts to compress the range of numbers required in measuring vibration. Similar to the noise descriptors, Leq and Lmax can be used to describe the average vibration and the maximum vibration level observed during a single vibration measurement interval.

The State of California defines sensitive receptors as those land uses that require serenity or are otherwise adversely affected by noise events or conditions. Schools, libraries, churches, hospitals, single and multiple family residential, including transient lodging, motels and hotel uses make up the majority of these areas. Sensitive receptors that may be affected by project generated noise include the single-family residential dwelling units located east of the project site and multiple family residential units located north of the project site.

B. Ambient Noise Measurements

An American National Standards Institute (ANSI Section SI4 1979, Type 1) Larson Davis model LxT sound level meter was used to document existing ambient noise levels at six locations in the project vicinity (see Figure 4).

As shown in Table 2, existing noise levels in the project vicinity range between 58.5 and 65.6 dBA Leq. Noise measurement field sheets and data are provided in Appendix A.

11 IV. Regulatory Setting
The proposed project may impact sensitive receptors located within the jurisdiction of the City of El Cajon (single family residences located east of the project site) as well as sensitive receptors located within the County of San Diego (multiple family residences located north of the project site).

A. City of El Cajon General Plan
General Plan Policy 8-3.8 states that the City may require site design considerations such as increased setbacks, sound attenuating walls and landscaping, and may also require building design considerations such as type of construction, insulation, and orientation of building openings in order to minimize noise impacts from noise sources.

B. City of El Cajon Municipal Code

1. Construction Noise
Per section 17.115130(C)(3) of the City of El Cajon Municipal Ordinance it is unlawful for any person within any residential zone, or within a radius of five hundred (500) feet from any residential zone, to operate equipment or perform any outside construction, maintenance or repair work on buildings, structures, landscapes or related facilities, or to operate any pile driver, power shovel, pneumatic hammer, power hoist, leaf blower, mower, or any other mechanical device, between the hours of 7 p.m. of one (1) day and 7 a.m. of the next day in such a manner that a reasonable person of normal sensitivities residing in the area is caused discomfort or annoyance.

The ordinance above does not specify a noise level limit at which a reasonable person of normal sensitivities would experience discomfort or annoyance. For purposes of this analysis, the Federal Transit Administration (FTA) Transit Noise and Vibration Impact Assessment (2006) criteria will be used to establish significance thresholds. The FTA provides reasonable criteria for assessing construction noise impacts based on the potential for adverse community reaction. For residential uses, the daytime noise threshold is 80 dBA L eq averaged over an 8-hour period (Leq (8-hr); and the nighttime noise threshold is 70 dBA Leq (8-hr). For commercial uses, the daytime and nighttime noise threshold is 85 dBA Leq (8-hr). In compliance with the City’s Code discussed in the previous paragraph, it is assumed that construction would not occur during the noise-sensitive nighttime hours.

2. Operational Noise
The City’s Municipal Code section 9.44.010, Noise, prohibits loud and disturbing noises. It specifies that no person shall make, continue or cause to be made or continued, within the limits of the City, any loud, disturbing, or unusual noise which injures or endangers the health, peace, or safety of persons of reasonable sensibilities: provided, that this section shall not in any way affect, restrict or prohibit any activities incidental to scientific or industrial research or manufacturing, construction or repairing conducted in areas zoned for such purposes.

Notes:
1 Where outdoor noise levels are higher, additional noise attenuation measures, i.e., earphones for workers, increased insulation, double-pane glass, may make noise levels acceptable.

3. Groundborne Vibration

City of El Cajon Municipal Ordinance Section 17.115.130(D), Performance Standards prohibits operations that could generate groundborne vibration that is harmful or injurious to the use or development of surrounding properties. Specifically, No vibration shall be permitted which is perceptible without instruments at any use along the property line on which such use is located.

For the purpose of this determination, the boundary is the property line. This standard is prohibitive for use several commonly used pieces of construction equipment which may be perceptible if used within 75 feet of a property line. It is our professional opinion that this ordinance applies to operational vibration sources, i.e., generators, Heating and Ventilation (HVAC) equipment and pumps.

Caltrans has prepared one of the most comprehensive manuals (Caltrans 2020) regarding the analysis of groundborne vibration. It contains reasonable standards for both the potential to be annoying and the potential to result in structural damage. As shown in Table 4, vibration is considered to be distinctly perceptible at a PPV of 0.04 in/second and strongly perceptible at 0.10 peak particle velocity (PPV). Table 5 shows that the threshold at which there is a risk to “architectural” damage to historic and some older buildings is a peak particle velocity (PPV) of

0.25 in/sec, at older residential structures a PPV of 0.3 in/sec, and at new residential structures and modern commercial/industrial buildings a PPV of 0.5 in/sec.

Therefore, impacts would be significant if construction activities result in groundborne vibration of 0.3 PPV or higher at residential structures and/or a PPV of 0.5 or higher at commercial structures. Annoyance is temporary in nature and is not considered significant unless it is strongly perceptible and disturbs sleep or the use of sensitive equipment (approximately 0.1 PPV).

C. County of San Diego

The properties located north of the project site are currently developed with multiple family residential dwelling units. The property has a zoning of Urban Residential (RU). The County of San Diego has adopted a guidance document1 for the preparation of noise studies which establishes exterior noise level limits that apply to the transmission of noise from one property to another.

The daytime noise standard (7:00 AM to 10:00 PM) to avoid impacts to properties zoned RU is 50 dBA Leq and the nighttime noise standard (10:00 PM to 7:00 AM) is 45 dBA Leq.

14 V. Analytical Methodology and Impact Analysis
A. Methodology

1. FTA Construction Noise Calculations
Noise levels at nearby sensitive receptors due to project construction noise were calculated utilizing methodology presented in the Federal Transit Administration (FTA) Transit Noise and Vibration Impact Assessment Manual (2018) together with key construction parameters including: distance to each sensitive receiver, equipment usage, percent usage factor, and baseline parameters for the project site. Distances to receptors were based on the acoustical center of the proposed construction activity. Construction noise levels were calculated for each phase.

2. SoundPLAN
The SoundPLAN acoustical modeling software was utilized to model project operational worst-case stationary noise impacts from the proposed project to adjacent sensitive uses (e.g., residences). SoundPLAN is capable of evaluating stationary noise sources (e.g., parking lots, drive-thru menus, carwash equipment, vacuums, etc.) and much more. The SoundPLAN software utilizes algorithms (based on the inverse square law) to calculate noise level projections. The software allows the user to input specific noise sources, spectral content, sound barriers, building placement, topography, and sensitive receptor locations. In addition to the information provided below, noise modeling input and outputs assumptions are provided in Appendix B.

Peak hour operational noise levels were modeled utilizing representative sound levels in the SoundPLAN model. Modeled noise sources include the parking lot noise, heating, and ventilation (HVAC) equipment and car wash noise. All noise sources were modeled to be in full operation for an entire hour. This is a conservative modeling effort, given that in actuality, several noise sources are not in operation continuously for an entire hour.

For the purposes of the modeling, it was assumed that the proposed dealership will not have outdoor amplification of music or voice, and all car maintenance and repair related stalls will be enclosed inside the proposed building. Express lube doors will be used for vehicle access but will be kept closed. No impact equipment or air compressors will be utilized in the express lube area. Other modeling assumptions are discussed below.

Car Wash Equipment Noise
The car wash drying system is by far the loudest noise source associated with the car wash tunnel. A sound power level representative sound pressure level of 103 dBA Leq at a distance of 10 (provided by the car wash manufacturer) was used to model car wash dryer noise. A point noise source was placed five feet from the opening of the end of the car wash tunnel at a height of eight feet to represent dryer noise. The dryer system was assumed to be operational for the entire period.

15 Parking Lots
Parking lot noise was calculated using SoundPLAN methodology. Specifically, the traffic volume of the parking lot is entered with the number of moves per parking bay, the hour, and the number of parking bays. The user defines whether the parking lots are for automobiles, motorcycles, or trucks, and the emission level of a parking lot is automatically adjusted accordingly. The values for the number of parking moves for each time slice is the number of parking moves per reference unit (most often per parking bay), averaged for the hour2.

SoundPLAN utilizes parking lot noise emission levels from the 6th revised edition of the parking lot study “Recommendations for the Calculation of Sound Emissions of Parking Areas, Motorcar Centers and Bus Stations as well as of Multi-Story Car Parks and Underground Car Parks” published by the Bavarian Landesamt für Umwelt provides calculation methods to determine the emissions of parking lots.

The parking lot emission table documents the reference level (Lw,ref) from the parking lot study.

Lw, ref = Lw0 + KPA + KI + KD + KStrO + 10 log(B) [dB(A)] With the following parameters:

Lw0 = Basic sound power, sound power level of one motion/per hour on P+R areas = 63 dB(A) KPA = Surcharge parking lot type
KI = Surcharge for impulse character
KD = Surcharge for the traffic passaging and searching for parking bays in the driving lanes 2,5 * lg (f * B-9)
f = Parking bays per unit of the reference value
B = Reference value
KStrO = Surcharge for the road surface

HVAC
A rooftop HVAC plan is not available at the time of this analysis so the exact location and number of units per building were estimated. A noise reference level for a 5-Ton Carrier Heating and Cooling (HVAC) unit was utilized to represent rooftop 5 Ton Carrier HVAC units.

HVAC units were assumed to be evenly spaced across the rooftop. The noise source height for each HVAC unit was assumed at 0.1 meter above the roof top. An average roof top height of thirty-five feet was utilized for modeling purposes.

3. Caltrans Transportation and Construction Vibration Guidance Manual

Groundborne vibration associated with project construction, at nearby sensitive receptors was modeled using methodologies and source amplitudes provided in the Caltrans Transportation and Construction Vibration Guidance Manual (2020).

16 VI. Impact Analysis and Findings

1. Construction Noise

The existing residential uses located north and east of the project site may be affected by short-term noise impacts associated with construction noise. Construction noise will vary depending on the construction process, type of equipment involved, location of the construction site with respect to sensitive receptors, the schedule proposed to carry out each task (e.g., hours and days of the week) and the duration of the construction work.

Construction phases will include demolition, site preparation, building construction, paving and architectural coating. Noise levels at nearby sensitive receptors due to project construction noise were calculated utilizing methodology presented in the FTA Transit Noise and Vibration Impact Assessment Manual (2018) together with several key construction parameters (see Appendix C). Typical noise levels and usage factors associated with a variety of construction is presented in Table 6. Tables 7 and 8 present cumulative noise levels associated with each phase of construction at receptors located north and east of the proposed project.

As discussed previously, the City of El Cajon has not established a specific noise level limit at which a reasonable person of normal sensitivities would experience discomfort or annoyance. Therefore, for purposes of this analysis, the FTA criteria was used. For impacts to residential land uses, the daytime noise threshold is eighty dBA Leq averaged over an 8- hour period (Leq (8-hr); and the nighttime noise threshold is 70 dBA Leq (8-hr). As shown in Tables 7 and 8, construction noise is expected to range between 62.6 and 74.5 dBA Leq at the southern property line of the multiple family residences located north of the project site and between 59.6 to 71.5 dBA Leq at the western property line of the existing single family residential uses east of the project site and will not exceed the FTA daytime 80 dBA (8-hour) noise criteria. Impacts related to construction would be less than significant. In compliance with the City’s Code discussed in the previous paragraph, it is assumed that construction would not occur during the noise-sensitive nighttime hours. Impacts would be less than significant. No mitigation is required.

21 2. Operational Noise
Operational noise was modeled using the SoundPLAN noise model. The results shown in Figures 5 and 6, show that operational noise is expected to range between 38.6 to 58.0 at nearby sensitive receptor property lines and will not exceed the City of El Cajon Noise Ordinance standard of 60 dBA Leq. These findings are based on a specific car wash drying system (one fixed nozzle with a noise level of 88.5 dBA Leq at a distance of ten feet) (See Appendix B), or if an equivalent or a quieter system is utilized. This impact would be less than significant. No mitigation is required.

3. Groundborne Vibration
The most vibratory pieces of equipment expected to be utilized on the project site include a vibratory roller and a larger bulldozer. It is anticipated that the existing parking lot will be re-purposed and tools necessary for asphalt removal will not be used. The use of a vibratory roller and/or a large bulldozer however may be used as close as 105 feet to the multiple family residential land use property line to the north and as close as line 120 to the single- family property line to the east.

Groundborne vibration levels associated with the use of a vibratory roller could reach up to

0.02 PPV at the property line associated with the multiple family residential land uses to the north and up to 0.10 PPV at the property line pof the single-family residential land uses to the east. Groundborne associated with the large bulldozer would be less (see Appendix D).

As stated previously, vibration is considered to be distinctly perceptible at a PPV of 0.04 in/second and strongly perceptible at 0.10 peak particle velocity (PPV); and the threshold at which there is a risk to “architectural” damage to historic and some older buildings is a peak particle velocity (PPV) of 0.25 in/sec, at older residential structures a PPV of 0.3 in/sec, and at new residential structures and modern commercial/industrial buildings a PPV of 0.5 in/sec.

Groundborne vibration associated with project construction will not be perceptible at nearby sensitive receptors and will not occur during nighttime hours or affect sensitive equipment. Furthermore, project construction will not result in groundborne vibration levels that come close to the threshold for potential damage to structures. This impact would be less than significant. No mitigation is required.

4. Airport/Aircraft Noise
The project site is located approximately 3,580 feet southwest of the Gillespie Field. As shown in Figure 7 the project site is not located within a 60 dBA CNEL or any louder noise contour associated with this airfield. However, the site is located within the airfield’s avigation easement and overflight notification areas. Visitors and employees at the project site will occasionally be subject to aircraft overflight. However, review of data provided in Noise Study

City Council
Agenda Report
Agenda Item 101.

DATE: 12/13/2022
TO: Honorable Mayor and City Councilmembers
FROM: Michael Viglione, Senior Planner
SUBJECT: Neighborhood Healthcare Expansion Project
RECOMMENDATION:

That the City Council:

Opens the public hearing and receives testimony;1.

Closes the public hearing;2.

Moves to adopt the next Resolution, in order, APPROVING the Negative Declaration; 3.

Moves to adopt the next Resolution, in order, APPROVING General Plan Amendment No. 2021-0002; and

4. Moves to introduce the next Ordinance, in order, APPROVING Zone Reclassification No. 2021-0001.

5. PROJECT DESCRIPTION:

The application proposes a General Plan Amendment ("GPA") to change the General Plan Land Use designation from Medium Density Residential to Office/Non-Retail (“O/NR”) and a corresponding Zone Reclassification ("ZR") from RM-2200 ("Residential, Multi-family, 2,200 square foot") to O-P ("Office Professional") to enable Neighborhood Healthcare to operate a medical clinic providing primary and general health care services by right. Aside from tenant improvements, no alterations or development are proposed. The subject property is located on the southwest corner of the intersection of East Madison and North Mollison Avenues and is addressed as 470 North Mollison Avenue.

BACKGROUND:

General Plan: MR (Medium Density Residential)
Specific Plan: Specific Plan (SP) No. 513
Zone: RM-2200 (Residential, Multi-family, 2,200 square foot) Other City Plan(s): CUP No. 116; CUP No. 2020-0008
Notable State Law(s): California Environmental Quality Act, No Net Loss Law Applicant: Neighborhood Healthcare
Project Site & Constraints
The project site is approximately 77,000 square feet—1.77 acres. The site includes a 12,504 square foot structure, 121 parking spaces, and approximately 7,400 square feet of landscaped area. The site has entrances from both East Madison and North Mollison Avenues and shares interconnecting access for parking with the Neighborhood Healthcare medical clinic to the north.

Surrounding Context
The properties surrounding the project site are developed and zoned as follows:

Direction Zones Land Uses
North O-P Neighborhood Healthcare Clinic
South RM-2200 Key Largo Apartments
East RM-2200 The Terraces Apartments
West RS-6 Cajon Valley Middle School Park
General Plan
The land use designation of the subject property is MR ("Medium Density Residential") according to the General Plan Land Use Map. The MR designation is intended to accommodate residential density between 18 and 20 dwelling units per acre.

Municipal Code/Zoning Code
The zone for the subject site is RM-2200, which identifies various non-residential uses that may be considered in residential zones. While religious facilities, government buildings and service facilities, day care facilities, and non-profit service organizations devoted to serving the general public may operate in RM-2200, a medical clinic is not permitted to operate in a residential zone.

Specific Plan No. 513
The subject property and the adjacent medical clinic property to the north (Neighborhood Healthcare) are governed by Specific Plan ("SP") No. 513. The SP was approved by the City Council in 2008 in conjunction with an expansion of the adjacent medical clinic and provides for 16 parking spaces on the subject property in perpetuity.

Conditional Use Permit No. 116
In 1961, Conditional Use Permit ("CUP") No. 116 authorized development of a religious facility at the subject site. The church building was expanded as recently as 1978 but remained largely unchanged thereafter. The church was the most recent, active use.

Conditional Use Permit No. 2020-0008
On December 1, 2020, El Cajon Planning Commission granted CUP No. 2020-0008 authorizing the operation of a non-profit community service center at the subject site. The center proposed to offer enrollment services for programs like Cal Fresh, Medicare MediCal, as well as housing assistance, job counseling, job training, and translation services, among other things. Though a tenant improvement building permit was issued, alterations are not complete and the use has not commenced.

Government Code section 65863 (No Net Loss Law)
Government Code section 65863 (No Net Loss Law)
No Net Loss Law requires a jurisdiction to maintain a sufficient supply of adequate sites in its housing element throughout the housing element planning period to meet a jurisdiction’s unmet share of the Regional Housing Needs Allocation ("RHNA") for each income category. To comply with the No Net Loss Law, jurisdictions must ensure their actions do not create a shortfall of available sites when making decisions regarding zoning and land use (e.g. downzoning). The City’s Housing Element does not identify the subject property in its Sites Inventory and therefore, the remaining sites in the Housing Element are adequate to accommodate the City’s RHNA.

DISCUSSION
Land Use and Zoning
After obtaining CUP No. 2020-0008 for the service center at the subject site, the applicant determined that an expansion of their capacity to meet the community demand for medical services would best suit operational needs. As indicated in the preceding section, the existing land use and zoning permits up to 20 residential dwelling units per acre and limited non-residential uses. However, a medical clinic is not a permitted use. Consequently, a GPA proposing a change in designation from Medium Density Residential to Office/Non-Retail and a corresponding ZR proposing a change in zone from RM-2200 to O-P is requested to enable the applicant to operate a medical clinic by right at the subject site. Neighborhood Healthcare anticipates offering primary and general health care services including, acupuncture, chiropractic, and women’s health and pre-natal care during regular business hours.

The larger area surrounding the subject property consists of single- and multi-family residential zones, primarily RS-6 and RM-2200 respectively, and includes institutional uses such as schools. O-P zoned properties are, however, immediately adjacent to the subject site as well.

Neighborhood Healthcare currently operates a medical clinic at 855 E Madison to the northwest of the subject site, while the properties along the north side of the East Madison and North Mollison intersection are also zoned O-P and in commercial use.

The General Plan recognizes that areas devoted to office or non-retail businesses may be located in close proximity to residential provided their operations are compatible. Such restrictions are already implemented in the Zoning Code through the Office-Professional zone, which primarily limits uses in the O/NR designation to office related uses, and the performance standards, which outline operational requirements related to noise, air quality, odor, property upkeep and other nuisances. Noise standards include daytime, evening, and nighttime noise thresholds to ensure compatibility between any proposed use and adjacent residential uses.

Similarly, property upkeep standards ensure the exterior landscape areas and parking lot are maintained in a sanitary condition, free of trash and debris. Furthermore, the environmental assessment found that potential impacts of glare, odor, and noise would be less than significant with the anticipated medical clinic use.

General Plan Goals, Objectives and Policies also accommodate the proposed GPA and ZR.

General Plan policy 9-4.13, indicates that commercial areas shall be integrated with well-designed interconnecting access between adjacent commercial developments. As stated earlier, SP No. 513 creates a permanent shared parking arrangement between the adjacent commercial property addressed as 855 East Madison and the subject site to maximize parking and access efficiency. Policy 9-4.4 also encourages commercial activities to be located so as to benefit from the access afforded by major streets such as East Madison and North Mollison, which are identified as secondary thoroughfares in the Circulation Element. The proposed GPA and ZR are consistent with the General Plan and are appropriate for the area. and ZR are consistent with the General Plan and are appropriate for the area.

Traffic and Parking
Pursuant to the parking standards in section 17.185.190 of the Zoning Code, general office uses require one (1) space per 250 square feet of gross floor area up to 10,000 square feet, plus one (1) space per 300 square feet for the next 15,000 square feet. Therefore, the parking requirement for an office use, like a medical clinic, in the existing 12,504 square foot building is 48 spaces. The project site must also include 16 offsite parking spaces pursuant to SP No. 513, as discussed above. Accordingly, a total of 64 spaces must be available on the project site.

Project plans show a total of 121 parking spaces, exceeding the minimum Zoning Code and Specific Plan requirements.

It is important to note that no intensification of parking or traffic demand is anticipated between the approved social service center under CUP No. 2022-0008 and the medical clinic, if the GPA and ZR are approved. The social service center and the anticipated medical clinic have the same parking requirements. Moreover, traffic generation for these uses is equivalent based on parking demand.

PLANNING COMMISSION RECOMMENDATION:

On November 15, 2022, the Planning Commission held a duly noticed public hearing for the requested General Plan Amendment and Zone Reclassification. Speakers at the public hearing included representatives of Neighborhood Healthcare and another individual in support of the project. After the public hearing was closed, the Planning Commission voted 5-0 to adopt Resolution Nos. 11084, 11086, and 11087 recommending City Council approval.

FINDINGS:

General Plan Amendment No. 2021-0002
A. The City has complied with applicable California Government Code sections regarding amendments to the Land Use Element of the General Plan.

The proposed amendment to the General Plan Land Use Element to change the designation of the subject site to Office/Non-Retail is in conformance with applicable Government Code sections because California Native American tribes identified by the Native American Heritage Commission were notified pursuant to Government Code section 65352.3 for the purpose of preserving or mitigating impacts to cultural places, features, and objects. A single request for consultation was received from San Luis Rey Band of Mission Indians but was ultimately withdrawn. The proposed amendment is the first amendment to the Land Use Element in the calendar year, and is consistent with the Government Code section 65358 prohibition on more than four amendments to a required General Plan Element within a calendar year.

B. The proposed General Plan amendment will not be detrimental to the public health, safety, or welfare, and is in the public interest.

The change in land use designation from Medium Density Residential to Office/Non-Retail continues the Office/Non-Retail land use designation for the immediately adjacent property and those at the north side of the intersection of North Mollison and East Madison Avenues. It also facilitates investment into the property and creates an integrated commercial office area with access to major streets consistent with General Plan Policies 11-1.2, 9-4.4, and 9-4.13.

C. The proposed General Plan amendment is internally consistent with the remainder of the C. The proposed General Plan amendment is internally consistent with the remainder of the General Plan, as required by Government Code section 65300.5 The proposed amendment does not compromise any policies found in the other General Plan Elements, including the Housing Element, because the subject property is not in the Sites Inventory and therefore, remaining sites in the Housing Element are adequate to accommodate the City’s Regional Housing Needs Allocation. Furthermore, it is consistent with Environmental Justice Element Goal 7 to increase health care services for the surrounding area. It will also improve the quality of the neighborhood by facilitating investment into the property through the assignment of land use permissions better suited to the existing conditions and improvements on the property.

Zone Reclassification No. 2021-0001
A. The proposed zoning amendment, including any changes proposed in the various land uses to be authorized, is compatible with the objectives, policies, general land uses, and programs specified in the general plan.

The proposed Zone Reclassification from RM-2200 to O-P is consistent with the proposed change of the General Plan Land Use Designation to Office/Non-Retail pursuant to the General Plan Zoning Consistency Chart. The proposed zone would further provide for offices and other compatible non-retail businesses in close proximity to residential areas as anticipated in the General Plan. Moreover, the proposed amendment will create an appropriately integrated medical facility consistent with General Plan Land Use Element Policies 9-4.4 and 9-4.13, and Environmental Justice Element Goal 7, and will further facilitate investment into the property consistent with Land Use Policy 11-1.2, which seeks quality development of all kinds .

B. The proposed zoning amendment is consistent with any applicable specific plan governing development of the subject property.

The proposed amendment is consistent with Specific Plan No. 513 as it preserves the 16 required offsite parking spaces for the adjacent healthcare clinic to the north.

C. It is in the public necessity and convenience and/or general welfare that the zoning regulations governing the property be changed.

The proposed zone change will encourage the use of an underutilized property through the creation of an integrated commercial area with land use permissions that are better suited to existing conditions and improvements. The zone change will expand health care access in the Bostonia Environmental Justice Community identified in the Environmental Justice Element and bring additional jobs and economic opportunity to the area.

D. When a reduction in residential density is proposed, the following additional finding shall be made: The remaining sites identified in the housing element are adequate to accommodate the city’s share of the regional housing needs pursuant to California Government Code sections 65584 and 65863.

The subject site was developed with an assembly building, which dates to April of 1962 and has The subject site was developed with an assembly building, which dates to April of 1962 and has remained a non-residential use since that time. Furthermore, the adopted Housing Element does not identify the subject property in its Sites Inventory and therefore, remaining sites in the Housing Element are adequate to accommodate the City of El Cajon’s Regional Housing Needs Allocation.

CALIFORNIA ENVIRONMENTAL QUALITY ACT:

In accordance with California Environmental Quality Act ("CEQA"), an Initial Study and Negative Declaration ("ND") were prepared for the proposed General Plan Amendment and Zone Reclassification. The ND evaluated potential environmental impacts of the proposed use against the most recent use of the property, the former church, and determined that the proposed project could not have a significant effect on the environment.

A Notice of Intent to Adopt the Negative Declaration was published on August 12, 2022, and the ND was circulated for public review and comment from August 12 – August 31, 2022. One comment letter was received from the California Department of Transportation ("Caltrans"). The Caltrans letter generally requested clarification of the City’s Vehicle Miles Travelled ("VMT") assessment thresholds, recommended strategies to reduce vehicle trips, and requested appropriate permits and coordination with Caltrans where the agency has jurisdiction. A response is included with the final ND which broadly reiterates the threshold and clarifies that there are no impacts to Caltrans rights-of-way.

PUBLIC NOTICE & INPUT:

Consistent with the requirements of Government Code section 65352 et seq., authorized representatives of California Native American Tribes identified by the Native American Heritage Commission were sent notice of the proposed General Plan Amendment on June 28, 2022 and July 21, 2022 via Certified Mail. A single request for consultation was received during the 90-day period provided by Government Code from the San Luis Rey Band of Mission Indians however it was later withdrawn on September 7, 2022.

Notice of this public hearing was mailed on November 3, 2022, to all property owners within 300 feet of the project site and to anyone who requested such notice in writing, and was similarly published in East County Gazette the same day in compliance with Government Code sections 65090, 65091, and 65092, as applicable. Additionally, as a public service, the notice was posted in the kiosk at City Hall and was also mailed to the two public libraries in the City of El Cajon, located at 201 East Douglas Avenue and 576 Garfield Avenue.

City staff did not receive any comments in response to the Notice of Public Hearing prior to preparation of this report. Comments received after publication will be presented to the City Council at the hearing.

RECOMMENDATION:

Staff’s recommendation is that the City Council approve the proposed General Plan Amendment and Zone Reclassification. The request creates an integrated medical office facility and support system to the community.

ORDINANCE NO. _____

AN ORDINANCE REZONING PROPERTY LOCATED ON THE

WEST SIDE OF NORTH MOLLISON AVENUE BETWEEN EAST
MADISON AND EAST PARK AVENUES AND ADDRESSED AS 470
NORTH MOLLISON FROM RM-2200 (RESIDENTIAL, MULTI-FAMILY, 2,200 SQUARE FOOT) TO O-P (OFFICE PROFESSIONAL) ZONE; APN:
488-061-17-00; PENDING GENERAL PLAN DESIGNATION:

OFFICE/NON-RETAIL (O/NR)

WHEREAS, the City Council considered proposed General Plan Amendment No. 2021-0002 to amend the general plan designation of the property from Medium Density (MR) Residential to Office/Non-Retail (O/NR) and adopted Resolution No. -22; and

WHEREAS, the City Council held a duly advertised public hearing on December 13, 2022, to consider Zone Reclassification No. 2021-0001, to change the zone from RM- 2200 ("Residential, Multi -family, 2,200 square foot") to the O-P ("Office Professional") zone; and

WHEREAS, at the public hearing the City Council received evidence through public testimony and comment, in the form of both verbal and written communications and reports prepared and presented to the City Council.

NOW THEREFORE, THE CITY COUNCIL OF THE CITY OF EL CAJON DOES ORDAIN AS FOLLOWS:

SECTION 1. Based upon the record as a whole, the City Council hereby makes the following findings:

A. The proposed Zone Reclassification from RM -2200 to O -P is consistent with the proposed change of the General Plan Land Use Designation to Office/Non- Retail pursuant to the General Plan Zoning Consistency Chart. The proposed zone would
further provide for office and other compatible non- retail businesses in close proximity to residential as anticipated in the General Plan. Moreover, the proposed amendment will create an appropriately integrated medical facility consistent with General Plan Land Use Element Policies 9- 4.4 and 9-4.13, and Environmental Justice Element Goal 7, and will further facilitate investment into the property consistent with Land Use Policy 11-

1.2 which seeks quality development of all kinds

B. The proposed amendment is consistent with Specific Plan No. 513 as it preserves the 16 required offsite parking spaces for the adjacent healthcare clinic to the north.

C. The proposed zone change will encourage the use of an underutilized property through the creation of an integrated commercial area with land use permissions that are better suited to existing conditions and improvements. The zone change will expand health care access in the Bostonia Environmental Justice Community identified in the Environmental Justice Element and bring additional jobs and economic opportunity to the area.

D. The subject site was developed with an assembly building which dates to April of 1962 and has remained a non- residential use since that time. Furthermore, the adopted Housing Element does not identify the subject property in its Sites Inventory and therefore remaining sites in the Housing Element are adequate to accommodate the City of El Cajon’s Regional Housing Needs Allocation.

SECTION 2. That based upon said findings of fact, the City Council hereby rezones the subject property on the west side of North Mollison Avenue from RM-2200 to the O-P zone in accordance with the attached Exhibit "A", and subject to the condition that all other land use entitlements benefitting the subject property shall be null and void upon effectiveness of this Zone Reclassification.

SECTION 3. This ordinance shall become effective thirty (30) days following its passage and adoption.

A RESOLUTION APPROVING GENERAL PLAN AMENDMENT NO.
2021-0002 TO AMEND THE LAND USE ELEMENT OF THE GENERAL

PLAN BY REDESIGNATING THE PROPERTY LOCATED ON THE

WEST SIDE OF NORTH MOLLISON AVENUE BETWEEN EAST
MADISON AND EAST PARK AVENUES AND ADDRESSED AS 470

NORTH MOLLISON AVENUE FROM MEDIUM DENSITY RESIDENTIAL
(MR) TO OFFICE/NON-RETAIL; APN: 488-061-17-00.

WHEREAS, the El Cajon Planning Commission held a duly advertised public hearing on November 15, 2022, to consider General Plan Amendment No. 2021-0002, to change the land use designation from Medium Density Residential (MR) to Office/Non- Retail, as submitted by Mike DeLeon on behalf of Neighborhood Healthcare; and

WHEREAS, the City Council reviewed and considered the proposed Initial Study and Negative Declaration for the project in accordance with CEQA Guidelines, and adopted Resolution No. -22; and

WHEREAS, the City Council held a duly advertised public hearing on December 13, 2022, to consider General Plan Amendment No. 2021-0002, to change the land use designation from Medium Density Residential (MR) to Office/Non-Retail; and

NOW, THEREFORE, BE IT RESOLVED BY THE CITY COUNCIL OF THE CITY OF EL CAJON AS FOLLOWS:

Section 1. The City Council finds that:

A. The proposed amendment to the General Plan Land Use Element to change the designation at the subject site to Office/Non- Retail is in conformance with applicable Government Code sections because California N ative American tribes identified by the Native American Heritage Commission were notified pursuant to Government Code section 65352.3 for the purpose of preserving or mitigating impacts to cultural places, features, and objects. A single request for consul tation was received from San Luis Rey Band of Mission Indians but was ultimately withdrawn. The proposed amendment is the first amendment to the Land Use Element in the calendar year consistent with the Government Code section 65358 prohibition on more than four amendments to a required General Plan Element within a calendar year.

Page 2 of 2 ends

B. The change in land use designation from Medium Density Residential to Office/Non-Retail continues the Office/Non- Retail land use designation from the immediately adjacent propert y and those on the north side of the intersection of North Mollison and East Madison Avenues. It also facilitates investment into the property and creates an integrated commercial office area with access to major streets consistent with General Plan Policies 11-1.2, 9-4.4, and 9-4.13.

C. The proposed amendment does not compromise any policies found in the other General Plan Elements, including the Housing Element because the subject property is not in the Sites Inventory and therefore, remaining sites in the Housing Element are adequate to accommodate the City’s Regional Housing Needs Allocation. Furthermore, it is consistent with Environmental Justice Element Goal 7 by increasing healthcare services to the surrounding area. It will also improve the quality of the neighborhood by facilitating investment into the property through the assignment of land use permissions better suited to the existing conditions and improvements on the property.

Section 2. That based upon said findings of fact, the City Council appr oves General Plan Amendment No. 2021-0002 to amend the Land Use Element of the General Plan by changing the General Plan designation of the property on the west side of North Mollison Avenue from Medium Density Residential to Office/Non- Retail, in accordanc e with the attached Exhibit “A”.

North Mollison Avenue

Project Description Medical Office—470 N. Mollison Ave., El Cajon

Neighborhood Healthcare is a non-profit healthcare service organization dedicated to serving the general public in El Cajon. Neighborhood has a clinic at 855 E. Madison Ave. That address and property is not a part of the current subject application.

Neighborhood also now owns the facility at 470 N. Mollison which is adjacent to the main clinic on Madison Ave. The N. Mollison building was a former church.

Neighborhood has been in El Cajon since 1994 and serves approximately 50,000 patient visits annually.

In consultation with city staff and the city manager, Neighborhood is now seeking a Zoning Reclassification of the former church property on N. Mollison to increases its capacity to serve the community and the neighborhood population’s medical needs.

The applicant also proposes limited social services as an accessory use not to exceed 15% of the gross floor area as allowed by city code at 17.115.110. A Zoning Reclassification and General Plan Amendment, along with an environmental Initial Study are required to make the program changes required. The Zoning designation of OP, Office Professional is proposed. A General Plan land use designation of Office/Non-Retail is also proposed with this action. There are no changes to the Site Plan with the current Zoning Reclassification and GPA.

The subject property APN is 488-061-17. The parcel is 1.77acres and is currently zoned RM2200. The general plan land use category is residential, multi-family. The parcel currently has a CUP 2020-008. Neighborhood will provide the following medical services upon approval of city council approvals, building permits and any necessary amendments and reclassifications.
 General and specialty medical exams
 Women’s Health

Geographically, to the north of the parcel are two story garden style multi-family residential zoned apartments with on street and onsite parking. Also nearby are some single-story commercial store fronts that are fronting Mollison Ave. with off

street parking in front of the commercial businesses. North of Mollison is Interstate 8, which is generally elevated to roof height above the neighborhood development.

To the east is additional two-story multi-family residential and some single story commercial stores fronting Madison Ave. El Cajon Valley High School is 3 blocks east of the subject site. To the south is two story multi-family residential. To the west, and immediately adjacent to the subject parcel, is the existing Neighborhood Healthcare medical clinic. Farther west is single story single family residential with small backyards and garages, El Cajon City Park and Cajon Valley Middle School. All the residential and commercial development is set back from the existing streets by sidewalks with landscape buffers.

Topographically, the site and adjoining residential and commercial are flat. The parcel is 100% developed with a 6,584 sq. ft single story building and attached 5,840sq ft two story classroom building. The existing buildings are a combination of painted CMUs and colored stucco over wood frame. The parking lot contains 5 ADA spaces, an ADA Path of Travel and 110 total parking spaces divided into an east and west parking lot separated by the former church and classroom buildings. No light standards are visible in the parking lots. Eight large palm trees are adjacent to the north and east edge of the church and classroom buildings. A painted attached wooden trellis is present along the southwest portion of the church building. Building setbacks are landscaped along the parcel frontage of Madison Ave. and Mollison Ave. There is a fire hydrant and covered bus stop for MTS Route 864 at the SW intersection of Madison and Mollison. Utilities are onsite serving the current buildings. A trash bin pad is located on the west parking lot without an enclosure, gates or a roof. Six-foot metal fencing is present at the property line on the west, south and some northerly portions of the subject parcel. There are no fences abutting street frontage along Madison or Mollison.

El Cajon, CA 92020
Dear Mr. Yiglione:

Thank you for including the California Department of Transportation (Caltrans) in the environmental review process for the Negative Declaration (NEG) for the Mollison Medical Office Building- General Plan Amendment GPA-2021-002; Zoning Reclassification ZR-2001-0001 Project located near Interstate 8 (1-8). The mission of Caltrans is to provide a safe and reliable transportation network that serves all people and respects the environment. The Local Development Review (LDR) Program reviews land use projects and plans to ensure consistency with our mission and state planning priorities.

Safety is one of Caltrans' strategic goals. Caltrans strives to make the year 2050 the first year without a single death or serious injury on California's roads. We are striving for more equitable outcomes for the transportation network's diverse users. To achieve these ambitious goals, we will pursue meaningful collaboration with our partners. We encourage the implementation of new technologies, innovations, and best practices that will enhance the safety on the transportation network. These pursuits are both ambitious and urgent, and their accomplishment involves a focused departure from the status quo as we continue to institutionalize safety in all our work.

Caltrans is committed to prioritizing projects that are equitable and provide meaningful benefits to historically underserved communities, to ultimately improve transportation accessibility and quality of life for people in the communities we serve.

We look forward to working with the City of El Cajon in areas where the City and Caltrans have joint jurisdiction to improve the transportation network and connections "Provide a safe and reliable transportation network that serves all people and respects the environment" A1

between various modes of travel, with the goal of improving the experience of those who use the transportation system.

Caltrans has the following comments:

Traffic Impact Study
• Due to the proximity of the project site location being within a quarter of a mile from the state highway on and off-ramps a Vehicle Miles of Travel (VMT) based Traffic Impact Study (TIS) and/or mobility study should be provided for this project. Please use the Governor's Office of Planning and Research Guidance to identify VMT related impacts. 1
• The TIS may also need to identify the proposed project's near-term and long-term safety or operational issues, on or adjacent any existing or proposed State facilities.
• The Governor's Office of Planning and Research Guidance states "Absent substantial evidence indicating that a project would generate a potentially significant level of VMT, or inconsistency with a Sustainable Communities Strategy (SCS) or general plan, projects that generate or attract fewer than 110 trips per day generally may be assumed to cause a less-than-significant transportation impact". • If ITE Guidelines of 500 ADT as a YMT threshold is the approved City YMT threshold, please identify this as the City Council approved YMT threshold.

Complete Streets and Mobility Network
Caltrans views all transportation improvements as opportunities to improve safety, access and mobility for all travelers in California and recognizes bicycle, pedestrian and transit modes as integral elements of the transportation network. Caltrans A2 supports improved transit accommodation through the provision of Park and Ride facilities, improved bicycle and pedestrian access and safety improvements, signal prioritization for transit, bus on shoulders, ramp improvements, or other enhancements that promotes a complete and integrated transportation network. Early coordination with Caltrans, in locations that may affect both Caltrans and the City of El Cajon is encouraged.

To reduce greenhouse gas emissions and achieve California's Climate Change target, Caltrans is implementing Complete Streets and Climate Change policies into State Highway Operations and Protection Program (SHOPP) projects to meet multi-modal mobility needs. Caltrans looks forward to working with the City to evaluate potential Complete Streets projects.

Bicycle, pedestrian, and public transit access during construction is important.

Mitigation to maintain bicycle, pedestrian, and public transit access during construction is in accordance with Caltrans' goals and policies.

Land Use and Smart Growth
Caltrans recognizes there is a strong link between transportation and land use.

Development can have a significant impact on traffic and congestion on State transportation facilities. In particular, the pattern of land use can affect both local vehicle miles traveled and the number of trips. Caltrans supports collaboration with local agencies to work towards a safe, functional, interconnected, multi-modal transportation network integrated through applicable "smart growth" type land use planning and policies.

The City should continue to coordinate with Caltrans to implement necessary improvements at intersections and interchanges where the agencies have joint jurisdiction.

Environmental
Caltrans welcomes the opportunity to be a Responsible Agency under the California Environmental Quality Act (CEQA), as we have some discretionary authority of a portion of the project that is in Caltrans' R/W through the form of an encroachment permit process. We look forward to the coordination of our efforts to ensure that Caltrans can adopt the alternative and/or mitigation measure for our R/W. We would appreciate meeting with you to discuss the elements of the EIR that Caltrans will use for our subsequent environmental compliance.

An encroachment permit will be required for any work within the Caltrans' R/W prior to construction. As part of the encroachment permit process, the applicant must provide approved final environmental documents for this project, corresponding technical studies, and necessary regulatory and resource agency permits. Specifically, CEQA determination or exemption. The supporting documents must address all environmental impacts within the Caltrans' R/W and address any impacts from avoidance and/or mitigation measures.
"Provide a safe and reliable transportation network that serves all people and respects the environment" Mr. Michael Yiglione, Senior Planner
August 29, 2022

Page 4 ends

We recommend that this project specifically identifies and assesses potential impacts caused by the project or impacts from mitigation efforts that occur within Caltrans' R/W that includes impacts to the natural environment, infrastructure including but not limited to highways, roadways, structures, intelligent transportation systems elements, on-ramps and off-ramps, and appurtenant features including but not limited to A5 lighting, signage, drainage, guardrail, slopes and landscaping. Caltrans is interested in any additional mitigation measures identified for the project's draft Environmental Document.

Should future projects based upon the changes enacted from the General Plan have elements and/or mitigation measures that affect Caltrans Right-of-Way, Caltrans would welcome the opportunity to be a Responsible Agency under the California Environmental Quality Act {CEQA).

Broadband
Caltrans recognizes that teleworking and remote learning lessen the impacts of traffic A6 on our roadways and surrounding communities. This reduces the amount of VMT and decreases the amount of greenhouse gas {GHG) emissions and other pollutants. The availability of affordable and reliable, high speed broadband is a key component in supporting travel demand management and reaching the state's transportation and climate action goals.

Right-of-Way
• Per Business and Profession Code 8771, perpetuation of survey monuments by a licensed land surveyor is required, if they are being destroyed by any construction. • Any work performed within Caltrans' R/W will require discretionary review and A7 approval by Caltrans and an encroachment permit will be required for any work within the Caltrans' R/W prior to construction.

Additional information regarding encroachment permits may be obtained by contacting the Caltrans Permits Office at { 619) 688-6158 or emailing [email protected] or by visiting the website at
https://dot.ca.gov /programs/traffic-operations/ep . Early coordination with Caltrans is strongly advised for all encroachment permits. "Provide a safe and reliable transportation network that serves all people and respects the environment" Mr. Michael Yiglione, Senior Planner

"Provide a safe and reliable transportation network that serves all people and respects the environment" Responses to Caltrans Letter
A1 As CEQA lead agency, the City can adopt its own standards for assessing projects transportation impacts. As stated on page 36 of the Draft IS/ND, the City requires a traffic study or Vehicle Miles Traveled (VMT) analysis for any project that generates 500 average daily trip (ADT) that is not in conformance with the General Plan, in accordance with the 2019 SANTEC/ITE guidelines. Given that the proposed medical office building would generate 348 net new daily trips, neither a traffic impact study nor a VMT analysis is required for the project in accordance with the City’s criteria.

A2 Comment noted; no transportation or street improvements are proposed or required within the Caltrans right-of-way. The City supports the state policies with regard to Complete Streets where it is relevant to projects.

A3 During project construction, no public right-of-way improvements are proposed and all access to bicycle, pedestrian and public transit in the project area would be maintained, as required by the City.

A4 Comment noted; refer to response to comment A1. There is no joint jurisdiction on the project.

A5 Comment noted; the project does not require any permits from Caltrans and no Responsible Agency requirements under CEQA.

A6 The City acknowledges that broadband access can be one of many methods for reducing vehicular trips and GHG emissions; however, based on the limited amount of traffic generated by the project, there is no requirement for travel demand management measures.

A7 As noted in response to comment A2, there is no work proposed within the Caltrans right-of-way and an encroachment permit is not required by the project.

Subject: RE: SB-18 Consultation - Mollison Office Building Project (APN: 488-061-17-00) 2 Hi Cami,

It seems we are playing phone tag so I thought I’d try email instead. Are there some times over the next two weeks when you might be able to meet for a consultation? I’d be happy to reserve a conference room at City Hall, set up a Zoom meeting, or meet elsewhere.

That said, I’d also like to put together an agenda for our consultation. Are there specific topics, such as those identified in Public Resources Code section 21080.3.2, you’d like to cover during this meeting? I will have project documents available for the consultation. I would like to clarify however that a Geotechnical Report for ground disturbance, as referenced in your consultation request, will not be available. There is no ground disturbance with this project as it is limited to a change in land use permissions and an interior tenant improvement, architectural coatings for the building (e.g. stucco etc), and restriping the lot.

Please let me know and we’ll get something scheduled.

Thanks!

City of El Cajon Mollison Medical Office Building Initial Study/Environmental Checklist November 2022 and Negative Declaration
6 8. Description of Project:

The project is a General Plan Amendment (GPA) and zoning reclassification application for the Mollison Medical Office Building (project). The project site is designated Medium Density Residential (MR) in the City’s General Plan and zoned Residential, Multi -Family (RM-2200). The project proposes a GPA to change the existing land use from MR to Office/Non-Residential (O/NR). The zoning reclassification would reclassify on-site zoning from RM-2200 to Office Professional (O-P) for consistency with the GPA. The project site currently operates under CUP-#116 overlaid for church use, which would be rescinded upon project approval.

The project site, Assessor’s Parcel Number (APN) 488-061-17, is 1.77 acres in size. The project would convert an existing, vacant church building to a medical office building that would provide medical and limited social services to the local community.

Neighborhood Healthcare (Neighborhood) is a non-profit healthcare service organization that would occupy the building. Besides changing its use, the interior of the structure would be reconfigured for office use; no changes to the exterior to the building or surrounding site are proposed. The project would comply with the building setback, height, and massing regulations contained in the City Zoning Code. The project would also include the application of architectural coatings for the building exterior and restriping of the surface parking lot.

Neighborhood would provide the following medical services at the project site:
 General and specialty medical exams
 Women’s health
 Obstetrician/gynecological exams
 Acupuncture treatments
 Chiropractic treatments
 Prenatal counseling and education
In addition, a limited amount of social services would be offered to the public at the project site, in concert with a partnership with Interfaith Community Services.

The project site is fully developed and consists of 121-space paved surface parking lot, a single-story building previously used as a church, with an attached two-story classroom building. The single-story church building is 6,584 square feet and the attached, two- story classroom building is 5,840 square feet. The church and classroom building are a combination of painted concrete masonry units and colored stucco over wooden frame.

The parking lot contains 6 American with Disabilities Act (ADA) spaces, an ADA path of travel, and 115 total parking spaces divided into an east and west parking lot separated by the church and classroom building. One overhead light pole is present in the parking area, adjacent to East Madison Avenue. Eight large palm trees are adjacent to the north and east edge of the church and classroom building. A painted, attached wooden trellis is present along the southwest portion of the church building. Building setbacks are landscaped along the parcel frontage of East Madison Avenue and North Mollison Avenue. There is a fire hydrant and covered bus stop for Metropolitan Transit System (MTS) Route 864 at the southwest intersection of East Madison and North Mollison Avenues. Utilities are present on site, serving the existing building. A trash bin pad is located on the west parking lot, without an enclosure, gates, or a roof. Six -foot metal fencing is present on the west, south, and along some northerly portions of the project Project Description
Initial Study/Environmental Checklist City of El Cajon Mollison Medical Office Building and Negative Declaration November 2022
7 site. There are no fences abutting the street frontage along East Madison or North Mollison Avenues.

The existing parking lot would continue to provide 121 parking spaces, consisting of 6 ADA parking stalls and 115 standard parking stalls to comply with the parking requirements of the project. The project would not result in alterations to the existing site access that is provided via driveways on East Madison and North Mollison Avenues.

See Figures 1 and 2 showing the project location and site plan.

The project does not propose utility improvements. No changes to existing drainage and stormwater collection on the project site would occur. The existing landscaping would remain intact.

Construction would include building interior reconfiguration consisting of demolition and improvements, the application of architectural coatings on the exterior of the structure and restriping of the surface parking lot. Overall, project construction activities would occur over a period of five months, with a planned opening of the medical office building in December 2022.

9. Surrounding Land Uses and Setting (briefly describe the project's surroundings):

The project site is in the central portion of the City, approximately 1,000 feet south of Interstate 8 (I-8). The property is a level, developed lot, situated in a largely residential neighborhood, at the southwest corner of the East Madison Avenue/North Mollison Avenue intersection. To the north of the project site, land uses consist of two-story multi-family residential uses, with some commercial uses fronting North Mollison Avenue. To the east, land uses include two-story multi-family residential and commercial fronting East Madison Avenue, with El Cajon Valley High School located beyond the adjacent multi-family residential. Two-story multi-family residential uses are located south of the project site. To the west, and immediately adjacent to the project site, is a medical clinic operated by Neighborhood Healthcare. Farther west is El Cajon City Park and Cajon Valley Middle School, with a small number of single-family residences located directly north of El Cajon City Park.

10. Other public agencies whose approval is required (e.g., permits. financing approval. or participation agreement):

None.

11. Have California Native American tribes traditionally and culturally affiliated with the project area requested consultation pursuant to Public Resources Code Section 21080.3.1? If so. is there a plan for consultation that includes, for example, the determination of significant impacts to tribal resources, procedures regarding confidentiality, etc.?
The Barona Band of Mission Indians, Jamul Indian Village of California, and Mesa Grande Band of Indians, which are traditionally and culturally affiliated with the geographic area within the City of El Cajon’s jurisdiction, requested formal notice of and information on proposed projects within the City. On June 28, 2022 and July 21,2022, in compliance with Government Code Section 65352 (Senate Bill [SB] 18), the City, as Lead Agency, sent a letter to the applicable tribes identified by the Native American Heritage Commission (NAHC) notifying them of the proposed project, its location on an in-fill site and its lack of ground disturbance. To date, oneA request for consultation was received from the San Luis Rey Band of Mission Indians tribe but it was subsequently withdrawn on September 7, 2022. No other consultation requests were received. as discussed in Section XVIII of this Initial Study; should additional responses be received during public Project Description

Environmental Factors Potentially Affected
Initial Study/Environmental Checklist City of El Cajon Mollison Medical Office Building and Negative Declaration November 2022
11 ENVIRONMENTAL FACTORS POTENTIALLY

AFFECTED
The environmental factors checked below would be potentially affected by this project, involving at least one impact that is a “Potentially Significant Impact”, as indicated by the checklist on the following pages. It is concluded that the project would result in the following potentially significant adverse environmental impacts to the following resource areas:
☐ Aesthetics ☐ Agriculture and Forestry
Resources
☐ Air Quality
☐ Biological Resources ☐ Cultural Resources ☐ Energy
☐ Geology and Soils ☐ Greenhouse Gas Emissions ☐ Hazards and Hazardous Materials
☐ Hydrology and Water
Quality
☐ Land Use and Planning ☐ Mineral Resources
☐ Noise ☐ Population and Housing ☐ Public Services
☐ Recreation ☐ Transportation ☐ Utilities and Service
Systems
☐ Tribal Cultural Resource ☐ Wildfire ☐ Mandatory Findings of Significance

DETERMINATION
On the basis of this initial evaluation (select one):
☒ I find that the proposed project COULD NOT have a significant effect on the environment, and a NEGATIVE DECLARATION will be prepared.
☐ I find that although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because revisions in the project have been made by or agreed to by the project proponent. A MITIGATED NEGATIVE DECLARATION will be prepared. ☐ I find that the proposed project MAY have a significant effect on the environment, and ENVIRONMENTAL IMPACT REPORT is required.
☐ I find that the proposed project MAY have a significant effect(s) on the environment, but at least one effect: (1) has been adequately analyzed in an earlier document pursuant to applicable legal standards; and (2) has been addressed by mitigation measures based on the earlier analysis as described on attached sheets, if the effect is a “potentially significant impact” or “potentially significant unless mitigated”. An ENVIRONMENTAL IMPACT REPORT will be required, but it must analyze only the effects that remain to be addressed.
☐ I find that although the proposed project could have a significant effect on the environment, there WILL NOT be a significant effect in this case because all potentially significant effects (a) have been analyzed adequately in an earlier EIR or Mitigated Negative Declaration pursuant to applicable standards and (b) have been avoided or mitigated pursuant to that earlier EIR or Mitigated Negative Declaration, including revisions or mitigation measures that are imposed upon the proposed project. Nothing further is required.

Evaluation of Environmental Impacts

12 Signature Date

EVALUATION OF ENVIRONMENTAL IMPACTS
Each of the responses in the following environmental checklist considers the whole action involved, including project-level, cumulative, on-site, off-site, indirect, construction, and operational impacts. A brief explanation is provided for all answers and supported by the information sources cited:

1. A “No Impact” answer is adequately supported if the referenced information sources show that the impact simply does not apply to projects like the one involved (e.g., the project falls outside a fault rupture zone).

2. A “Less-than-Significant Impact” applies when the proposed project would not result in a substantial and adverse change in the environment. This impact level does not require mitigation measures.

3. A “Less-than-Significant Impact with Mitigation Incorporated” applies when the proposed project would not result in a substantial and adverse change in the environment after mitigation measures are applied.

4. “Potentially Significant Impact” is appropriate if there is substantial evidence that an effect is significant. If there are one or more “Potentially Significant” entries when the determination is made, an EIR is required.

I. AESTHETICS. Except as provided in Public Resources Code Section 21099, would the Project:
a) Have a substantial adverse effect on a scenic
vista?
☐ ☐ ☐ ☒
b) Substantially damage scenic resources,
including, but not limited to, trees, rock
outcroppings, and historic buildings within a
state scenic highway?
☐ ☐ ☐ ☒
c) Substantially degrade the existing visual
character or quality of public views of the site
and its surroundings?
☐ ☐ ☒ ☐
d) Create a new source of substantial light or glare
that would adversely affect day or nighttime
views of the area?
☐ ☐ ☐ ☒

Project Impacts and Mitigation Measures
a) The project would consist of interior reconfiguration, including demolition and improvements, application of architectural coatings for the building exterior, and restriping the surface parking lot. Visible changes outside of the building would be limited to exterior painting and parking lot restriping. The project site is fully developed, and the project does not include components that would result in alterations to the building mass or scale. The project site is located within the valley portion of the City and is not located within Hillside overlay areas. Policies of the General Plan that protect scenic resources are focused on protecting views of the surrounding open space system and not the valley floor. As such, the project would not have a substantial adverse effect on a scenic vista, and no impact would occur. b) The project site is located along North Mollison Avenue, approximately 1,000 feet south of I-8 in the central portion of the City. I-8 is not a designated state scenic highway nor does the City’s General Plan identify roadways in the project area as scenic. Changes to the project site would not be visible from I-8. No impact associated with scenic resources within a state scenic highway would occur. c) The project site is zoned RM-2200, which allows for moderately dense residential development, and the project would process a zone reclassification to O-P. The project would convert an existing, vacant church to a medical office building that would provide medical services to the local community. Besides changing the use, the interior of the structure would be reconfigured for office use; no changes to the exterior to the building (except application of architectural coatings) or surrounding site (except parking lot restriping) are proposed. The project would comply with the Environmental Analysis
II. Agriculture and Forestry Resources
City of El Cajon Mollison Medical Office Building Initial Study/Environmental Checklist November 2022 and Negative Declaration
14 building setback, height and massing regulations contained in the City Zoning Code.

Policies of the General Plan that protect scenic resources are focused on protecting views of the surrounding open space system and not the valley floor. As noted above under response I.a, the project occurs on a fully developed site in the valley area of the City that would not adversely impact views from or to scenic vistas. The proposed office use would not change the mass or scale of the building and would continue to be consistent with the existing development patterns in the area. Thus, the project would conform to applicable zoning and other regulations governing scenic quality. The project would improve the existing visual quality of the site and would not degrade visual character as viewed from the adjacent public roads. A less- than-significant impact would occur.
d) The project is proposed on a fully developed site in an urbanized area. The project site contains an existing light fixture in the parking lot, as well as minor exterior lighting on the building. The project would ensure that lighting sufficient for safety is integrated into the project, as necessary, to comply with City Municipal Code Section

17.130.150. As the only exterior changes to the building would include the application of architectural coatings, the project would not result in new sources of glare. Thus, no impact associated with substantial new sources of light and glare would occur as a result of the project.

II. AGRICULTURE AND FORESTRY RESOURCES. In determining whether impacts to agricultural resources are significant environmental effects, lead agencies may refer to the California Agricultural Land Evaluation and Site Assessment Model (1997) prepared by the California Dept. of Conservation as an optional model to use in assessing impacts on agriculture and farmland. In determining whether impacts to forest resources, including timberland, are significant environmental effects, lead agencies may refer to information complied by the California Department of Forestry and Fire Protection regarding the state’s inventory of forest land, including the Forest and Range Assessment Project and the Forest Legacy Assessment project; and the forest carbon measurement methodology provided in Forest protocols adopted by the California Air Resource Board. Would the Project:
a) Convert Prime Farmland, Unique Farmland, or
Farmland of Statewide Importance (Farmland),
as shown on the maps prepared pursuant to the
Farmland Mapping and Monitoring Program of
the California Resources Agency, to
nonagricultural use?
☐ ☐ ☐ ☒
b) Conflict with existing zoning for agricultural use,
or a Williamson Act contract?
☐ ☐ ☐ ☒
c) Conflict with existing zoning for, or cause
rezoning of, forest land (as defined in Public
Resources Code Section 12220(g)), timberland
(as defined by Public Resources Code
Section 4526), or timberland zoned Timberland
Production (as defined by Government Code
Section 51104(g))?

nature, could result in conversion of Farmland
to nonagricultural use or conversion of
forestland to non-forest use?
☐ ☐ ☐ ☒

Project Impacts and Mitigation Measures
a–d) The project site is located in an existing urbanized area with no agricultural or forest resources within the vicinity. The site is mapped as Urban and Built-Up Land in the California Important Farmland Finder system operated by the California Department of Conservation. The project site is not zoned for agricultural or forestry purposes; and there is not a Williamson Act Contract associated with the site or in the vicinity.

Therefore, the project would not convert Important Farmland, conflict with agricultural zoning, or otherwise cause the conversion of farmland or forest land to non-agricultural/non-forest use. The project would have no impact to agriculture and forestry resources.
e) The project consists of interior improvements, the application of architectural coatings, and parking lot restriping on a developed parcel. There are no agricultural uses or forest land uses on-site or in the vicinity of the project site. Therefore, the project would not result in the significant conversion of farmland or forest land to a non-agriculture use. No impact would occur.

a) The project site is located within the San Diego Air Basin (Basin). The California Air Resources Board coordinates and oversees both State and federal air pollution control programs in California. The California State Implementation Plan (SIP) is the document that sets forth the State’s strategies for attaining the National Ambient Air Quality Standards. The San Diego Air Pollution Control District (SDAPCD) is the agency responsible for preparing and implementing the portion of the California SIP applicable to the Basin. The SDAPCD has adopted air quality plans to improve air quality, protect public health, and protect the climate. The San Diego Regional Air Quality Strategy (RAQS) outlines SDAPCD’s plans and control measures designed to attain and maintain the state standards, while San Diego’s portions of the SIP are designed to attain and maintain federal standards. The RAQS are based on the growth projections of the San Diego Association of Governments (SANDAG) and land use plans developed by the cities and by the County. As such, projects that propose growth consistent with city and the County land use plans, and thus consistent with the growth anticipated by SANDAG, would be consistent with the RAQS and SIP.

Development consistent with the City’s General Plan would be consistent with the RAQS and SIP.

The project site is designated for residential use in the General Plan. The proposed project includes a GPA to change the General Plan land use to Office/Non-Retail (O/NR). While the project is not consistent with the existing General Plan designation, the GPA to change the General Plan land use to Office/Non-Retail (O/NR) would not exceed the General Plan growth assumptions in the RAQS and SIP because the GPA would change the site from a residential use (which has the potential to increase population growth) to an office use (which is non-population- Environmental Analysis

17 inducing). As such, even though a GPA is required for the project, the project would not conflict with or obstruct implementation of the applicable air quality plan because it would not result in growth in excess of that anticipated by SANDAG. Impacts would be less-than-significant.
b) Both the State and the Federal governments have established health-based ambient air quality standards for seven air pollutants. These pollutants include ozone, carbon monoxide, nitrogen dioxide, sulfur dioxide, particulate matter smaller than or equal to 10 microns in diameter, particulate matter smaller than or equal to 2.5 microns in diameter, and lead. In addition, California maintains ambient air quality standards for sulfates, hydrogen sulfide, vinyl chloride, and visibility-reducing particles. These standards are designed to protect public health and welfare.

Project implementation would produce temporary pollutant emissions durin g construction and long-term operational emissions. Temporary emissions during construction would be generated by vehicles used by construction workers, and by vehicles used for debris removal. Due to the minor amount of construction equipment required for the project, consisting of interior building improvements, application of architectural coatings, and parking lot restriping, construction emissions would be minimal. Because construction emissions would be minor and temporary in nature, lasting six or less months in time, impacts would be less-than- significant.

Operational air pollutant emissions would include those associated with stationary sources, energy sources, and mobile sources. Stationary sources associated with the project would come from landscape equipment, general energy use, and solid waste.

Energy emissions would come from electricity and natural gas use. Mobile source emissions would be generated due to personal vehicles use from employees, the public using project services, as well as deliveries and maintenance (estimated to be 435 average daily trips (ADT) based on the Medical Office Building ITE trip generation rate of 34.8 trips per 1,000 SF). Because of the small project size, project-related long-term operational emissions are expected to be minor and would result in less-than-significant impacts.
c) Sensitive receptors include schools, hospitals, resident care facilities, day care centers, or other facilities that may house concentrations of individuals with health conditions that would be adversely impacted by changes in air quality. Project construction is limited to interior building improvements, the application of architectural coatings, and parking lot restriping. While there are two schools located with 0.25 mile (El Cajon Valley High School is located approximately 700 feet to the east and Cajon Valley Middle School is located approximately 600 feet to the west), the proposed construction activities would be minimal and mainly occur within the interior of the building. The application of architectural coatings and parking lot restriping would temporarily emit very small amounts of toxic air contaminants.

Based on the minimal amount of construction activities proposed for the project, the project would not generate a substantial amount of pollutant concentrations.

Therefore, the project would not expose sensitive receptors to substantial pollutant concentrations and less-than-significant impacts would occur. d) Minor construction odors would be produced as a result of construction equipment use at the site and during application of architectural coatings and parking lot restriping; however, construction activities would primarily occur within the existing building, and odors associated with construction activity would largely be contained within the building. Odors that would occur would not be noticeable beyond the Environmental Analysis

City of El Cajon Mollison Medical Office Building Initial Study/Environmental Checklist November 2022 and Negative Declaration
18 project boundaries. Additionally, for the application of architectural coatings on the exterior of the building, and during parking lot restriping, minor odors would be short-term in nature and would not be expected to be noticeable beyond the project boundaries. The proposed medical office uses providing medical services to the public would not include odor-producing activities. As construction activities would be temporary in nature and no odors would occur during long-term operation of the project, impacts associated with odors would be less-than-significant.

19 Project Impacts and Mitigation Measures
a) The project site is located in an urbanized area and is fully developed with an existing building and surface parking lot and contains no suitable habitat for state and/or federally listed or regionally sensitive wildlife. Due to the project’s location in an urban environment and lack of biological resources at the project site, no impact associated with species identified as a candidate, sensitive, or special-status species in local or regional plans, policies, or regulations would occur. b-c) The project site is in an urbanized area and is fully developed with an existing building and surface parking lot. No wetlands or jurisdictional resources regulated by the United States Army Corps of Engineers, California Department of Fish and Wildlife or Regional Water Quality Control Board occur within or immediately adjacent to the project site. Therefore, the project would have no impact to any riparian habitat or other sensitive natural community, and no impact to jurisdictional areas or federally protected wetlands would occur.
d) The site is in an urbanized area and is not adjacent to an open space or wildlife corridor; nor does the site itself serve as a wildlife corridor or nursery site. No impact related to the movement of wildlife through corridors would occur. e-f) The City does not have an approved MSCP Subarea Plan in place. The project site is not located within a Habitat Conservation Plan or within the vicinity of any local, regional, or state conservation plan. The project site is fully developed and is located within an urbanized area. Therefore, no impact related to the project’s compliance with regional and state conservation plans would occur.

20 and local roads and infrastructure were put in. The project site does not contain any listed historical resources and the project does not propose removal of the existing structures. Therefore, implementation of the project would not create a substantial adverse change in the significance of a historical resource as defined in Section 15064.5, and no impact would occur.
b) Due to its fully developed state and the proposed project improvements, which do not include ground disturbance, the project would not result in potential impacts to archaeological resources. Therefore, the project would not cause a substantial adverse change in the significance of an archaeological resource, and no impact would occur.
c) The project would occur on a fully developed site and does not include ground disturbance. As such, the project would not have the potential to disturb human remains, including those located outside of formal cemeteries. No impact associated with the discovery of human remains would occur.

☐ ☐ ☒ ☐

Project Impacts and Mitigation Measures
a) Construction of the proposed project would result in temporary energy consumption and one-time, non-recoverable energy usage associated with interior demolition and improvements activities, the application of architectural coatings, and parking lot restriping. Energy consumption related to construction of the proposed project would primarily consist of the consumption of fossil fuels as a result of use of on-road vehicles for worker commutes and trucks for debris removal. The temporary demand for energy associated with construction would not, however, be excessive because of the minor amount of proposed construction, consisting of interior demolition and improvements, the architectural coatings application for the building, and parking lot restriping. This energy usage would be minor and would cease upon completion of the project construction activities.

The project’s operational energy usage would be minimized through compliance with the California Building Code Standards (i.e., California Code of Regulations [CCR] Title 24) and California Green Building Standards Code, as applicable to the project.

Therefore, the project would not result in the wasteful, inefficient, or unnecessary consumption of energy resources. Less-than-significant impacts would occur.

22 Project Impacts and Mitigation Measures
a) The project would not directly or indirectly cause potential substantial adverse effects, including the risk of injury, damage or death as follows:
i) Major known active faults in San Diego County include Rose Canyon, La Nación, Elsinore, San Jacinto, Coronado Bank, and San Clemente Fault Zones. La Nación is the closest of these faults, located approximately 10 miles west of El Cajon.

According to the City of El Cajon Safety Element, there are no Alquist-Priolo earthquake fault zones within the City. Since no active faults are known to transect the project site, ground surface rupture is unlikely. For this reason, no impact related to rupture of a known earthquake fault would occur. ii) The site is located in a seismically active area, as is the majority of southern California, and the potential for strong ground motion is considered significant.

Due to its presence in a seismically active area, the project would be subjected to a moderate to severe risk associated with ground shaking related to a large- magnitude earthquake on one of the regional faults noted above. The project does not include structural changes to the existing building or building foundation and thus, would not alter the suitability of building in regards to safety during seismic shaking. Impacts would be less-than-significant. iii) Liquefaction potential is based on soil strength and the presence of a shallow water table. Liquefaction occurs when soil is saturated with water and subject to a destabilizing force such as an earthquake, resulting in the soil behaving like a liquid. Liquefaction generally occurs during significant earthquake activity. Over half of the City, including the project site, is a liquefaction risk area, as shown on the City of El Cajon Safety Element Figure S-5. The project does not include structural changes to the existing building or building foundation, and thus, would not alter the suitability of building in regards to liquefaction risks. Impacts would be less-than-significant.
iv) Landslides in the El Cajon Valley are known to occur in the western slopes within the Friars Formation. The City of El Cajon Safety Element identifies the northwest portion of the City as the area with the most landslide risk but indicates that landslide risk areas occur throughout El Cajon. The project site and adjacent uses are located within the central portion of the City, within an urban area that is topographically level with no slopes or interface with natural sloping areas. The project site is fully developed, and the project does not propose structural changes to the existing building or building foundation. Based on the developed nature of the site, the flat topography of the site and surrounding areas, and lack of structural changes associated with the project, no impact associated with landslides would occur.
b) The project does not include ground disturbance, soil movement, or the exposure of soil. The project site is fully developed with a building, surface parking, and small landscaped areas adjacent to East Madison and North Mollison Avenues. As the project does not include ground disturbance or soil movement and the project site is fully developed, no impact associated with soil erosion or loss of topsoil would occur. c-d) The project site is fully developed with the existing building and surface parking.

During construction of the existing structure, soil would have been determined adequate for supporting building construction. Since the project would utilize the Environmental Analysis

regulation adopted for the purpose of reducing
the emissions of greenhouse gases?
☐ ☐ ☒ ☐

Project Impacts and Mitigation Measures
a) The City adopted its Sustainability Initiative in 2020, which is a plan to reduce greenhouse gas (GHG) emissions within its jurisdiction. The City does not have a qualified Climate Action Plan (CAP) and has not established a screening threshold for GHG emissions. As such, a project-specific greenhouse gas study (Bluescape Environmental 2022) was prepared using California Air Pollution Control Officers Association (CAPCOA) screening threshold as an emission level that would indicate project emissions would result in less-than-cumulatively-significant impacts and would not interfere with the ability of the state to achieve state reduction targets.

With the passage of Senate Bill (SB) 32, the state extended and increased its commitment to GHG reductions to 40 percent below 1990 levels by 2030. To accomplish this objective, the CAPCOA 900 MT CO2e screening threshold was reduced annually by 5 percent for projects with operational years of 2021 to 2030, to demonstrate compliance with the SB 32 target by 2030. In the case of the proposed project, which would become operational by 2023, a screening threshold of 765 MT CO2e is used for assessing the project’s GHG emissions (Bluescape Environmental 2022).

The project’s GHG emissions sources include mobile sources associated with construction (on-road vehicles for construction workers and potential haul trucks for demolition debris), and operational emissions from energy use (electricity and natural gas), solid waste, water use and transportation, with the majority of operational emissions being associated with vehicle trips. Area emissions include landscaping equipment, architectural coatings, and consumer products. In the case of the proposed project, GHG emissions estimates were calculated using the California Emissions Estimator Model (CalEEMod) software. The project-specific GHG Environmental Analysis
IX. Hazards and Hazardous Materials
City of El Cajon Mollison Medical Office Building Initial Study/Environmental Checklist November 2022 and Negative Declaration
24 study estimated the project’s construction emissions would be 1.08 MT CO2e amortized over 30 years, while the operational GHG emissions were estimated at 324.2 MT CO2e per year. When construction and operational emissions are combined and compared to the adjusted screening threshold of 765 MT CO2e, it was determined that the project would produce 325.3 MT CO2e per year, less than the screening threshold.

Additionally, an operational GHG emissions comparison between the former use of the building as a church and the proposed office uses was conducted to determine the difference in operational GHG emissions between the two land uses. The operational GHG emissions for the former church were calculated at 138.5 MT CO2e, while the project’s construction and operational emissions total 325.3 MT CO2e. The combined total GHG emissions for the project are higher than total GHG emissions associated with the previous use of the site as a church, due to increased energy and water usages and increased ADT of the medical office land use. However, the GHG emissions between the church uses and medical office uses are both well below the significance threshold of 765 MT CO2e. Therefore, the project would not generate GHG emissions in excess of the screening threshold and its impacts on climate change would be less-than-significant.
b) As discussed in response VIII.a, the project would generate GHG emissions that would not be cumulatively considerable. Further, the project’s GHG emissions would decline in the future based on regulatory forecasting. Vehicle emissions would continue to decline due to regulations that increase vehicle efficiency, and the development of alternative fuel vehicles and technologies. GHG emissions associated with energy and the transportation and treatment of water would continue to decrease, as San Diego Gas & Electric continues to increase renewable sources of energy in accordance with Renewable Portfolio Standard goals. Given the reasonably anticipated decline in project emissions, due to existing regulatory programs, once the project is fully constructed and operational, the project emissions would continue to decline in line with the GHG reductions needed to achieve the state’s interim (2030) and horizon-year (2050) goals established by AB 32 and SB 32. The project would not conflict with any local or state plan, policy, or regulation aimed at reducing GHG emissions from land use and development. Impacts would be less-than- significant.

Project Impacts and Mitigation Measures
a–b) The project consists of interior building improvements, application of exterior architectural coatings, and parking lot restriping on a parcel that is fully developed.

Proposed uses for the existing building are limited to medical office uses providing medical services to the public. During construction activities, hazardous materials may be present on site (such as fuels, lubricants, solvents, etc.); however, these materials would be present in small quantities and typical of those used in construction activities. These materials would be stored, handled, used, and disposed of by the construction contractor in accordance with applicable regulations and requirements, and would not create a significant hazard to the public or environment. Additionally, due to the age of the building, which was constructed in the early 1960s, there is potential for asbestos containing materials (ACM) or lead- based paint (LBP) to be present. During interior remodeling, the project would comply with regulatory requirements for testing and abating these materials. During long-term operation of the project, minor amounts of hazardous materials, such as cleaning materials, typical of an office setting would be present at the project site.

These materials would not be substantial or prone to accidental releases and would not create a significant hazard to the public or the environment. Additionally, the proposed medical uses would produce medical waste which could generate biohazardous waste and sharps. Medical waste would be handled and disposed of in accordance with existing regulations for medical waste. Impacts would be less-than- significant.

26 c) The nearest schools are El Cajon Valley High School, located approximately 700 feet to the east, and Cajon Valley Middle School, located approximately 600 feet to the west of the project site. The project would generate a small amount of temporary construction emissions during interior building improvements, application of architectural coatings, and parking lot restriping; however, these emissions would be minor and would only occur during the approximately five-month construction period. In the long-term, an office land use such as the project would not emit or handle acutely hazardous materials or waste. Medical waste would be handled and disposed of in accordance with existing regulations for medical waste. Therefore, impacts associated with the emission of hazardous materials within 0.25 mile of a school would be less-than-significant.
d) Based on a review of the California Department of Toxic Substances Control EnviroStor database, neither the project site nor directly adjacent properties are included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5. Therefore, no impact would occur. e) The project site is located approximately 1.8 miles southeast of Gillespie Field. In January 2010, the Regional Airport Authority adopted the Gillespie Field Airport Land Use Compatibility Plan (ALUCP). The project site is located in the Airport Influence Area (AIA) for the Gillespie Field, within Review Area 2 of the AIA. Review Area 2 consists of locations beyond Review Area 1 but within airspace protection and overflight notification areas. Limits on the heights of structures are the only restriction on land uses within Review Area 2. The project does not propose changes to the building height. Based on ALUCP Exhibit III-1, the project site is not located within noise compatibility contours for Gillespie Field, and thus, the project w ould not result in the exposure of people to excessive aircraft noise. The project is not within identified Safety Zones for Gillespie Field, as shown on ALUCP Exhibit III-2, and thus, the project would not result in safety hazards for people working at the project site.

There are no other public airports or airstrips in the project area. No impact would occur from safety hazards or noise from regional aircraft operations. f) Emergency access to and from the site would occur via the existing driveways on East Madison Avenue and North Mollison Avenue. The project does not require off- site improvements or temporary lane closures adjacent to the project site or along area roadways. The project would comply with the City’s requirements with regard to emergency access, as determined through site plan reviews by Heartland Fire and Rescue Department. Review of the site plan in accordance with these requirements would result in adequate emergency access, and no impact would occur. g) The project site is completely developed and is located in an urbanized area. The nearest area mapped as Very High Fire Hazard Severity Zone (VHFSZ) is approximately 1.5 mile west of the project site; therefore, the project site does not have a direct interface with areas designated as VHFSZ. The project does not propose exterior building modifications or new structures but would need to comply with fire code requirements; however, the site plan would be reviewed by the Heartland Fire and Rescue Department staff for compliance with the regulations.

Upon review of the project design to verify compliance with the applicable regulations, the project would have no impact related to wildfire risk.

Project Impacts and Mitigation Measures
a) The project site is fully developed with the existing building and surface parking.

Since the project would utilize the existing structure and parking lot, it would not alter the existing drainage conditions or impervious surface areas at the site. The change in land use from a church use to a professional office use would not alter the types of pollutants that would occur at the site, mainly associated with the continued use of the surface parking, such as oil and grease. Construction activities do not Environmental Analysis

City of El Cajon Mollison Medical Office Building Initial Study/Environmental Checklist November 2022 and Negative Declaration
28 include soil movement or removal of existing impervious areas. As the project site is already developed, runoff would be conveyed to an existing stormwater system already in place. Post-construction runoff would not increase the potential for urban contaminants since no operational changes are proposed to the parking area. Based on the lack of physical changes to the surface parking and building structure, and the lack of construction activities outside of the building, the project would not violate water quality standards or waste discharge requirements or otherwise substantially degrade surface or ground water quality. No impact would occur. b) The project does not propose the use of local groundwater supplies or the construction of groundwater wells. The project would rely on water service from the Helix Water District and not ground water supplies. The project site is fully developed, with impervious surfaces covering most of the site, except landscaped areas adjacent to the East Madison Avenue and North Mollison Avenue frontages.

The project would not result in changes to the impervious areas at the site and thus, would not result in changes to groundwater recharge. Therefore, the project would not substantially decrease groundwater supplies or interfere substantially with groundwater recharge such that the project may impede sustainable groundwater management of the basin. No impact would occur.
c) Drainage patterns on the project site would not be altered by the project. The project site is fully developed and consists mostly of impervious areas. Small, landscaped areas adjacent to the East Madison Avenue and North Mollison Avenue frontages provide the only pervious areas on the project site. As no soil movement would occur and the project would not result in the exposure of soil, no impacts associated with erosion or siltation would occur. The project does not propose changes or construction activities on the building exterior, except for the application of architectural coatings and parking lot restriping. These activities would not have the potential to change the rate or amount of surface runoff in a manner which would result in flooding on- or offsite, create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems, or provide substantial additional sources of polluted runoff. The northern portion of the project site, adjacent to East Madison Avenue, is within the 500-year floodplain, as mapped by the Federal Emergency Management Agency; however, a large portion of the project site, including the existing building, is not located within flood hazard zones.

As exterior work associated with the project is limited to the application of architectural coatings and parking lot restriping, the project would not result in alterations at the site that would impede or redirect flood flows. No impact associated with altering the exiting drainage of the project site would occur. d) As discussed above, no alteration to the existing site drainage would occur. The project site is outside any defined 100-year floodplains and is located approximately 18 miles inland from the Pacific Ocean, over 7 miles south of San Vicente Reservoir, and approximately 5 miles southwest of Lake Jennings. Due to these intervening distances, there would be no drainage or water quality impacts related to flood hazards or inundation by tsunami or seiche. No impact would occur. e) The project site is fully developed with the existing building and surface parking.

Since the project would utilize the existing structure and parking lot, based on the lack of physical changes to the surface parking and building structure, and the lack of construction activities outside of the building, the project would not conflict with or obstruct implementation of a water quality control plan or sustainable groundwater management plan. No impact would occur.

Project Impacts and Mitigation Measures
a) The project site is fully developed and located within an urbanized area. The project does not propose construction of new structures and building alterations would be limited to interior and minor exterior improvements. As such, construction of the project would not physically divide an established community. No impact would occur.
b) The project site is designated Medium Density Residential (MR) in the City’s General Plan and zoned RM-2200. The project proposes a GPA to change the existing land use from Medium Density Residential to Office/Non-Retail (O/NR). The zoning reclassification would reclassify on-site zoning from RM-2200 to Office Professional (O-P) for consistency with the GPA. While a GPA and zoning reclassification is required, the project would not result in inconsistencies with General Plan policies.

The project would convert an existing, vacant church to a medical office building that would provide medical services to the local community. The project would comply with the building setback, height and massing regulations contained in the City Zoning Code. As discussed in response III.a, the project would not result in conflicts with the RAQS and SIP, because the GPA would change the site use from a residential use (which has the potential to induce population growth) to an office use (which is non-population-inducing). Additionally, as discussed in response VIII.b, the project would not result in inconsistencies with GHG plans and regulations. The project would not result in land use consistency impacts associated with the Gillespie Field ACLUP, as discussed in responses IX.e and XIII.c. Therefore, the project would not cause a significant environmental impact due to a conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect. Less-than-significant impacts would occur.

Environmental Analysis
XIII. Noise
Initial Study/Environmental Checklist City of El Cajon Mollison Medical Office Building and Negative Declaration November 2022
31 Project Impacts and Mitigation Measures
a) Temporary, short-term noise would be produced during construction of the project.

Construction personnel, construction equipment, and materials deliveries to the site would incrementally increase noise levels on local roads leading to the site. Although there would be a relatively high single event noise exposure potential causing intermittent noise nuisance (passing trucks), the effect on longer-term (hourly or daily) ambient noise levels would be small when compared to existing hourly/daily traffic volumes on East Madison Avenue and North Mollison Avenue. Also, due to the nature of the construction activities, which would consist of interior demolition and improvements, the transport of construction material to the site would be less than a typical construction project, as no materials for building construction would be required. Construction vehicles accessing the project site would be temporary, vehicles speeds would be low, and the volume of traffic would not be substantial due to the small project size and the nature of the construction activities (limited to interior demolition and improvements, exterior building application of architectural coatings, and parking lot restriping). Therefore, short-term, construction-related noise impacts associated with worker commute and equipment/materials transport to the project site would be less-than-significant.

Noise generated during equipment usage on the project site would also result in short-term noise increases in ambient noise levels over the course of the construction schedule; however, construction does not include ground disturbance or exterior building construction activities and would not require the use of outdoor heavy equipment. Construction would occur within the building for interior demolition and improvements, and thus, noise would be reduced as compared to typical construction activities that require exterior equipment use and the use of heavy equipment. The City Noise Ordinance specifies maximum 1-hour average sound level limits at the boundary of a property. These maximum 1-hour sound level limits are the maximum noise levels allowed at any point on or beyond the property boundaries due to activities occurring on the property. For residential uses (such as the uses adjacent to the project site to the south), these limits are 60 dBA 1-hour sound level (Leq) between 7 a.m. and 7 p.m., 55 dBA Leq between 7 p.m. and 10 p.m., and 50 dBA Leq between 10 p.m. and 7 a.m. The project is subject to the provisions of the City Noise Ordinance, and therefore, temporary increases in ambient noise during construction would be less-than-significant.

In terms of permanent noise, on OP/NR use would generate traffic noise by adding 435 weekday ADT to local roads in the project area, assuming the Institute of Traffic Engineers (ITE) trip rate of 34.8 trips per thousand square feet for Medical Office Building (Bluescape Environmental 2022). The project would generate 107 ADT on Saturdays and 18 ADT on Sundays. For comparison, the ADT associated with church usage of the building was estimated at 87 weekday ADT, 75 ADT on Saturday, and 345 ADT on Sundays, based on the ITE trip rates for Place of Worship (Bluescape Environmental 2022). Therefore, during the weekday, the project would result in a net increase of 348 weekday ADT compared to the church use of the building. During weekends, the project would result in an increase of 32 Saturday ADT as compared to the church use and would result in a decrease of 327 Sunday ADT. Project traffic would primarily travel along East Madison Avenue and North Mollison Avenue for direct access to the site and would travel along other area roadways to access East Madison and North Mollison Avenues. A 3 dB change in noise levels is the minimum level required for a perceptible change in noise levels for the general population. In order to increase ambient road noise by 3 dB, a project would have to double the Environmental Analysis
XIV. Population and Housing
City of El Cajon Mollison Medical Office Building Initial Study/Environmental Checklist November 2022 and Negative Declaration
32 amount of traffic on that road (U.S. Department of Transportation 2018). East Madison Avenue between Magnolia Avenue and Ballantyne Street (which is one block west of the project site) carries approximately 8,700 daily trips, while East Madison Avenue east of Jamacha Road carries 10,400 daily trips (Chen Ryan 2016). North Mollison Avenue between East Main Street and Park Avenue (approximately one block south of the project site) carries approximately 17,900 daily trips (Chen Ryan 2016). The 348 additional weekday daily trips the project would add (in comparison to the church uses) to these roadways would not result in a doubling of traffic volume, and thus, would not cause a perceptible noise increase associated off-site roadway traffic. The amount of new vehicle trips attributable to the project would be very minor in comparison to the amount of existing traffic on nearby roads.

Therefore, the incremental increase in noise along roads in the project area attributable to project traffic would be imperceptible to local residents. A less-than- significant permanent impact to ambient noise levels would occur as a result of the project.
b) Groundborne vibration is almost exclusively a concern inside buildings and is rarely perceived as a problem outdoors, where the motion may be discernible, but without the effects associated with the shaking of a building there is less adverse reaction.

The project does not include components such as grading or ground disturbance that would require the use of heavy construction equipment. The proposed activities, consisting of interior building improvements, application of architectural coatings, and restriping the parking lot would not require the use of equipment that would generate groundborne vibration. Additionally, the proposed uses would not generate groundborne vibration during project operation. No impact would occur. c) No private airports occur in the project vicinity. The project site is located approximately 1.8 miles southeast of Gillespie Field. Based on ALUCP Exhibit III-1, the project site is not located within noise compatibility contours for Gillespie Field, and thus, the project would not result in the exposure of people to excessive aircraft noise. No impact would occur.

Therefore, the project does not include uses that would induce population growth, such as residential uses or large job-generating uses. The project does not propose components that would extend or increase infrastructure capacity in the project area, nor would it provide infrastructure to previously unserved areas. No new public roads are proposed, and the project would utilize existing utility infrastructure already present at the site. Therefore, the project site would not induce substantial unplanned population growth in the area. No impact would occur.

Project Impacts and Mitigation Measures
a) Fire protection services for the City are provided by Heartland Fire and Rescue Department, which maintains staff at eight fire stations. El Cajon Fire Station No. 6 is located at 100 East Lexington Avenue, approximately 0.7 mile southwest of the project site. El Cajon Fire Station No. 8 is located at 1470 East Madison Avenue is located approximately 1.3 miles west of the project site. The site would maintain its existing access points on East Madison Avenue and North Mollison Avenue, and as such, would be accessible by fire and emergency equipment. The church use of the building required fire protection services. The project would result in similar fire protection demand as the church use and would not necessitate the construction of new or expanded fire protection facilities. The project site is fully developed and is located in an urbanized area that has existing fire protection. Therefore, there would be no environmental impacts associated with serving the project site from existing fire and emergency response facilities. No impact would occur. b) Police protection for the City is provided by the El Cajon Police Department from its headquarters at 100 Civic Center Way. The project would provide medical services to Environmental Analysis
XVI. Recreation

34 existing residents within the City and would utilize an existing structure in an urbanized area. Based on the service of existing residents and the use of an existing structure, the project would not result in the need for new or altered police protection facilities. The demand for police protection services would be served from the existing police protection facilities. Therefore, there would be no environmental impacts associated with serving the project site from existing police protection facilities. No impact would occur.
c) The project site is located within the Cajon Valley Union School District and the Grossmont Unified High School District. The project is a medical office use that would provide medical services to existing residents in the area and would not result in increased need for school facilities. As such, no impact to school facilities would occur as a result of the project.
d) The project is a medical office use that would provide medical services to existing residents in the area. As such, the project would not result in increased demand on existing parks. No impact to parks would occur.

☐ ☐ ☐ ☒
d) Result in inadequate emergency access? ☐ ☐ ☐ ☒

Project Impacts and Mitigation Measures
a) The project does not include changes to the circulation system, including transit, roadway, bicycle, or pedestrian facilities. There is a covered bus stop for MTS Route 864 at the southwest intersection of East Madison and North Mollison Avenues, along the sidewalk adjacent to the project site. Bus stop access along the segment of Madison Avenue adjacent to the project site would be maintained during and after project construction. The property is, therefore, within the ¼ mile walkshed of a bus route. The El Cajon Bicycle Master Plan and Active Transportation Plan identify East Madison Avenue and North Mollison Avenue as having existing and proposed Class 2 bicycle lanes in the immediate project vicinity (KTUA 2011). There are no missing sidewalks for pedestrian usage along either road in the project vicinity, according to the Active Transportation Plan (City of El Cajon 2022). As the project does not include any off-site circulation work or changes to road configurations or conditions, it would not conflict with the City’s Bicycle Master Plan or the Active Transportation Plan. No changes or closures to the sidewalks would occur during project construction or operation; existing pedestrian access would be maintained. The project would not cause any changes to major roads, pedestrian facilities or bicycle facilities in the area. The project would not conflict with any adopted programs, plans or policies related to the local circulation system. No impact would occur. b) The project would generate 435 weekday ADT based on the ITE trip generation factor for Medical Office Building (i.e., 34.8 trips per 1,000 square feet). The project would generate 107 ADT on Saturdays and 18 ADT on Sundays. Daily trips associated with church usage of the building were estimated at 87 weekday ADT, 75 Environmental Analysis

36 ADT on Saturday, and 345 ADT on Sundays, based on the ITE trip rate for Place of Worship (Bluescape Environmental 2022). During the weekday, the project would result in a net increase of 348 weekday ADT compared to the church use of the building. During weekends, the project would result in an increase of 32 Saturday ADT, and a decrease of 318 Sunday ADT as compared to the church use. The City has not adopted guidelines for conducting either screening level or full vehicle miles traveled (VMT) analysis in accordance with Senate Bill 743. Therefore, the San Diego Region Guidelines prepared by the ITE were utilized to determine if the project has the potential for VMT impacts (ITE 2019). Based on the ITE guidelines, a project that is not consistent with the General Plan designation and generates less than 500 ADT would not require a VMT analysis. Based on the guidelines, the project generating 435 weekday ADT, a VMT analysis is not necessary for the project. Therefore, the project’s VMT impacts are presumed to be less-than-significant. c-d) The project site would maintain its existing access points on East Madison Avenue and North Mollison Avenue. No alterations to driveway configuration or site access are proposed. The restriping of the parking lot would maintain existing drive aisles in the parking area and would not place parking areas in such a way as to create design hazards or access issues. No changes to off-site streets are proposed and no construction activities would occur off site. The project would not create a geometric design feature that would substantially increase hazards in the project area. No impact would occur.

37 Project Impacts and Mitigation Measures
a) The project area was graded and heavily disturbed in the 1960s when the local neighborhood was established, and local roads and infrastructure were installed. The project site is fully developed, and to implement the project there would be no ground disturbance or removal of existing structures, pavement or landscaping at the site. Therefore, implementation of the project would not create a substantial adverse change in the significance of a historical resource as defined in Public Resources Code Section 5020.1(k), and no impact would occur. b) The Barona Band of Mission Indians, Jamul Indian Village of California, and Mesa Grande Band of Mission Indians requested to be informed through formal notification of proposed projects within El Cajon under the provisions of SB 18 and SB 52.

Because of the proposed General Plan Amendment, a SB 18 consultation was initiated when a formal notification letter containing a written description of the project, a project map, and lead agency contact information was sent to the authorized representatives on June 28, 2022 and July 21, 2022 in accordance with Government Code Section 65352. To date, a A request for consultation was received from San Luis Rey Band of Mission Indians and there is the potential for other tribes to request consultation during the 90-day periodbut it was subsequently withdrawn on September 7, 2022. Due to lack of ground disturbance associated with the project that would occur at the site and the consultation conducted to date, no impact to tribal cultural resources would are expected to occur as a result of the proposed project.

a–c) The project site is already served by existing water, wastewater, stormwater, electric power, natural gas, and telecommunications infrastructure. Wastewater and stormwater services are provided by the City. The project would use existing sewer mains in the project area. Water service would be provided to the project through existing water line connections that already serve the site and would be supplied by the Helix Water District. The project is not of sufficient size to require (pursuant to Senate Bill 221) a water supply assessment. While the project would result in an increase in demand above the existing levels required by the church and current vacant building, the demand for water, wastewater, stormwater treatment and other utilities would be similar in scale to that of the prior site use and would not result in the need for new or expanded facilities. No significant environmental effects would occur, and less-than-significant impacts are identified. d–e) The project would result in new medical office uses occurring in the existing building that would generate solid waste during construction and long-term operation.

Medical office uses would likely result in increased solid waste generation as Environmental Analysis

39 compared to church uses, due to the increased number of people present at the building on a daily (weekday) basis; however, compliance with the applicable provisions of the El Cajon Municipal Code would ensure that both short-term and long-term project-level impacts would not occur. For construction, the City encourages applicants for demolition and building permits to divert at least 65% of the waste generated on site. While construction waste is expected to be minor due to the proposed construction activities at the site, the interior demolition activities would generate construction debris, which would be handled and disposed of consistent with diversion goals and solid waste handling requirements. For operational waste, the City has granted an exclusive franchise agreement to EDCO for solid waste and disposal services in the City. The project would comply with the City’s implementation of the Source Reduction and Recycling Element (SREE), required pursuant to the State Legislature’s Integrated Waste Management Act, which mandated that all cities reduce waste disposal in landfills from generators within their borders. The incremental increase in solid waste associated with the project would not cause impacts on the City’s waste management goals. Therefore, solid waste impacts would be less-than-significant.

40 emergency access. City review of the site plan would result in adequate emergency access, and no impact would occur.
b) The project site is fully developed and located in an urbanized area. According to the City of El Cajon Safety Element Figure S-8, the project site is not located within or adjacent to Very High, High, or Moderate Wildfire Hazard Severity Zones. The nearest area mapped as VHFSZ is approximately 1.5 mile west of the project site; therefore, the project site does not have a direct interface with wildlands. The project includes interior improvements, exterior architectural coatings, and parking lot restriping. The interior project improvements would be subject to review by Heartland Fire and Rescue Department to ensure compliance with all fire code requirements contained in the El Cajon Municipal Code. Due to the lack of adjacent wildland interfaces and slopes and compliance with fire code requirements, the project would have less-than-significant impacts related to wildfire risk. c) The project would not require the installation or maintenance of associated infrastructure (such as roads, fuel breaks, emergency water sources, power lines or other utilities) that may exacerbate fire risk or that may result in temporary or ongoing impacts to the environment. The project would reuse the existing building and surface parking lot. Project improvements are limited to interior improvements, architectural coatings on the building exterior, and restriping of the parking lot. N o impact to the environment would occur related to fire infrastructure. d) The project site is situated in an urbanized area in the central portion of El Cajon and does not have a direct interface with wildlands or natural drainages. Therefore, the project would not expose people or structures to significant risks, including downslope or downstream flooding or landslides, as a result of runoff, post-fire slope instability, or drainage changes. No impact would occur.

The following are Mandatory Findings of Significance in accordance with CEQA Guidelines Section 15065.
a) The project site is fully developed, in an urbanized area. The project includes a GPA and a zoning reclassification, along with interior building improvements, exterior architectural coatings, and parking lot restriping. As the project would reuse the existing building and surface parking, no ground disturbance is required. Based on the urban location and nature of the project, the project does not have potential to substantially degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self- sustaining levels, threaten to eliminate a plant or animal community, or substantially reduce the number or restrict the range of a rare or endangered plant or animal. No existing vegetation would be removed by the project. In addition, due to the lack of ground disturbance for the project, there is a no potential for the project to result in the discovery of intact cultural resources or tribal cultural resources. Therefore, the project would not cause a substantial adverse change in the significance of a prehistoric or historic resource. No impact would occur.

42 b) As documented in this Initial Study, the project is proposed on a fully developed site in an urban area and would result in no impact or less-than-significant impacts. No mitigation is required for the project. As such, the project would not contribute to potentially significant cumulative environmental impacts. Impacts would be less- than-significant.
c) As discussed in this Initial Study, there are no hazardous conditions on the project site or in the surrounding area. Construction activities would not create hazardous conditions that would significantly directly or indirectly impact human beings. Any hazardous materials used at the site or removed from the site as part of the construction process would be handled in accordance with applicable regulations for the transport, use, storage, and disposal of such materials, ensuring that no substantial adverse effect on human beings would occur. Due to the age of the existing building, ACM or LBP may be encountered; however, removal and abatement of these materials in compliance with existing regulations would ensure they would not result in hazardous conditions. As described in this Initial Study, the project would not result in significant long-term impacts associated with air quality, geology, hazards or hazardous materials, hydrology/water quality, or noise, and as such, would not result in an adverse effect on human beings, either directly or indirectly. Impacts would be less-than-significant.

Neighborhood Healthcare Medical Professional Offices,
470 Mollison Ave. El Cajon, California

This memo outlines the greenhouse gas study performed for the Neighborhood Healthcare (Neighborhood) Medical Professional Offices project (Project), proposed to be located on 470 Mollison Avenue, in El Cajon, California in an existing building that was a church. The information contained in this memo is intended to accompany the environmental documentation in accordance with the California Environmental Quality Act (CEQA) for the initial study.

Project Description
Neighborhood Healthcare is a non-prof it healthcare service organization dedicated to serving the general public in El Cajon. Neighborhood has a clinic at 855 E. Madison Ave. That location serves approximately 50,000 patient visits annually. Neighborhood has been in El Cajon since 1994.

Adjacent to Neighborhood’s clinic is 470 N. Mollison, the site of a former church which Neighborhood leased as an overflow parking lot. An electric gate, owned by Neighborhood, separates the western church parking lot from Neighborhood’s western parking lot as well. Neighborho od purchased the church parcel in July of 2020. Neighbor hood proposes to remodel the interior of the former church to incorporate multiple professional and medical offices, with the primary use as a medical clinic and any associated patient/social services limited to 15% of floor area.

The existing property currently has a 12,504 square foot building, formerly occupying a church, and a 121-space parking lot associated with the building; the total lot area is 77,101.2 square feet. Neighborhood is seeking a General Plan Amendment and zoning reclassification to change the former church property’s land use designation from Medium-Density to Office- Medical/Professional and zoning from Residential Multi-family (RM-2200) to

Office-Medical/Professional. Neighborhood is requesting to allow for by-right use of the property as a medical clinic.

GHG Study Methodology
This Project is analyzed using the California Air Pollution Control Officers Association (CAPCOA) guidelines, which aims to streamline the review process for discretionary projects that require environmental review pursuant to CEQA, and CAPCOA’s 900 metric tons (MT) of carbon dioxide equivalent (CO2e). The 900 MT CO2e screening threshold was determined by CAPCOA as an emission level that would indicate project em issions would result in less than cumulatively significant impacts and would not interfere with the ability of the state to achieve state reduction targets, identified by Assembly Bill No. 32 (AB 32). Under AB 32, the state has reviewed its commitment to also reduce its GHG emissions to 40% below 1990 levels by 2030. Based on a linear regression, under the assumption that CAPCOA’s 900 MT CO 2e threshold is
applicable for projects up to operational year 2020, an annual reduction of 5% is applied to projects with operational years of 2021 to 2030, to demonstrate compliance with the SB 32 target by 2030. Based on the annual reduction rate, the 2023 project-specific screening level would be 765 MT CO 2e, a 15% reduction for operational year 2023.

GHG emission estimates were calculated using the California Emissions Estimator Model (CalEEMod), software version 2020.4.0. CalEEMod results are included as an attachment to this memo. An operational GHG emissions comparison was performed for the old land use type of “Place of Worship” and the new land use type of “Medical Office Building” to determine the difference in operational GHG emissions between the two land uses. The Project’s estimated GHG emissions were compared to a project specific 2023 threshold of 765 MT CO
2e.

CalEEMod Assumptions
Construction Scenario
Construction of the Project would generate temporary GHG emissions primarily from vehicles transporting construction workers to and from the site, with minimal indoor equipment use. Although all demolition activities will be done on the inside of the building, and emissions will be minimal, 32 cubic yards of demolition debris was input into CalEEMod as a conservative estimate for truck hauling emissions. Grading, site preparation, and paving phases of construction are not included in CalEEMod, due to the fact that the building will only be renovated on the interior and the parking lot is already constructed.

Construction may commence in June 2022 and it is estimated to take approximately 5 months to complete. The modeled construction schedule, which assumes a 5-day work week, is as follows:
 Interior Demolition (25 days)
 Building Renovation and Remodeling Construction (60 days) Neighborhood Healthcare Offices Greenhouse Gas Study

BlueScape Environmental 3 June 1, 2022

 Architectural Coating (20 days)
Operational Scenario – New Professional Offices
The first year of Project operations will be 2023. The land use types selected in CalEEMod for the Project were General Office Building, 12,504 sq. ft. and Parking Lot, 121 spaces. Because Neighborhood Healthcare will be providing both professional and medical services at the 470 Mollison Avenue building, default traffic volumes for a Medical Office Building were assumed in CalEEMod and are consistent with the characteristics of a medical office building.

Residential solid waste emissions are associated with municipal solid waste activities. In 2016, the California legislature adopted SB 1383 which targets a 50 percent reduction in the landfilling of organic waste in 2022, by recycling, composting, and other diversion measures. Since the Project operations begin in 2023, a 50% reduction in landfill organic waste generation was applied as a Project design feature.

Operational Scenario – Former Church
The church was modeled in CalEEMod as an existing operational source of emissions. The year of church operations was entered into CalEEMod as 2023 to demonstrate an equivalent annual comparison. The land use types selected in CalEEMod were Place of Worship, 12,504 sq. ft. and Parking Lot, 121 spaces.

Default traffic volumes for Place of Worship were applied in CalEEMod.

As with the offices, a 50% reduction in landfill organic waste generation was applied as a Project design feature in CalEEMod.

Construction Emissions
Table 1 shows the greenhouse gas emissions associated with construction.

TABLE 1.

CONSTRUCTION GREENHOUSE GAS EMISSIONS
Year
Annual Emissions
(MT CO2e/yr)
2022 32.3
Amortized over 30 years 1.08

The estimated greenhouse gas emissions for building remodeling construction activity would generate an estimated 32.3 MT of CO 2e in 2022. When amortized over a 30-year period, constr uction of the project would generate about 1.08 MT CO2e per year.

Operational Emission Sources
Operational emissions include energy use, solid waste, water use, and transportation. The majority of operational emissions are associated with Neighborhood Healthcare Offices Greenhouse Gas Study

Total Operational 138.5 324.2
Amortized Construction -- 1.08
Total Operation + Construction 138.5 325.3
Adjusted Screening Threshold -- 765
Exceeds Threshold? -- No
The combined total GHG emissions for the Project are approximately 325.3 MT CO2e. These emissions would not exceed the adjusted screening threshold of 765 MT CO2e, per year. The proposed medical office building is estimated to have higher total GHG emissions than the existing church, due to the increased potential for vehicle trips, energy and water usage. However, the medical offices are still well below the significance threshold.

Conclusions
GHG emissions associated with the 470 Mollison Avenue medical office building are estimated to be 325.3 MT CO
2e. Since Project emissions would not exceed
CAPCOA’s 900 MT CO2e threshold and the adjusted 765 MT CO 2e screening threshold annually, the Project would not generate a substantial increase in GHG emissions and Project impacts on climate change would be considered less than significant.
