construction standards. Other project improvements include adding school signage, developing perimeter fencing for security purposes, constructing curbs, ramps, and gutters; trenching along Georgia Street for underground utilities; removing/reconfiguring existing curbs to accommodate new parking; minor removal of shrubs and trees; adding a new ADA accessible ramp that would connect Sacramento Street to the rear entrance of the building; reconfiguring 16 parking spaces into eight parallel parking spaces along Sacramento Street, as well as adding 36 bicycle parking spaces. New perimeter fencing for security purposes, school signage, and 36 bicycle parking spaces would be included.
The school would operate Monday through Friday from 8:00 a.m. to 3:30 p.m. with occasional after-school activities and weekend events (e.g., parent engagement meetings). During the initial development phase, the school would house a maximum of 249 students, ten teaching staff, and 25 administrative staff. At full enrollment, there would be a maximum of 400 students and approximately 35 staff members.
NOISE FUNDAMENTALS
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 human ear. Noise is defined as loud, unexpected, or annoying sound. 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 obstructions or atmospheric factors affecting the propagation path to the receiver determine 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.
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). One mPa is approximately one hundred billionth (0.00000000001) 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 large 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).
Because decibels are logarithmic units, SPLs cannot be added or subtracted through ordinary arithmetic. Under the decibel scale, a doubling of sound energy corresponds to a 3-dB increase. In other words, when two identical sources are each producing sound of the same loudness, the resulting sound level at a given distance would be 3 dB higher than if only one of the sound sources were producing sound under the same conditions. For example, if one idling truck generates an SPL of 70 dB, two trucks idling simultaneously would not produce 140 dB; rather, they would combine to produce 73 dB. Under the decibel scale, three sources of equal loudness together produce a sound level 5 dB louder than one source.
The decibel scale alone does not adequately characterize how humans perceive noise. 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 in that range. In general, people are most sensitive to the frequency range of 1,000-8,000 Hz and perceive sounds within this range better than sounds of the same amplitude with frequencies outside of this range. To approximate the response of the human ear, sound levels of the individual frequency bands are weighted, depending on the human sensitivity to those frequencies. Then, an “A-weighted” sound level (expressed in units of A-weighted decibels) can be computed based on this information. The A-weighting dB (dBA) scale approximates the frequency response of the average young ear when listening to most ordinary sounds. When people make judgments of the relative loudness or annoyance of a sound, their judgment correlates well with the A-scale sound levels of those sounds.
Thus, noise levels are typically reported in terms of A weighted decibels. All sound levels discussed in this study are expressed in A-weighted decibels.

Common Noise Descriptors
Various time-averaging noise metrics are used in the field of acoustics, which can be chosen to better characterize the noise source in question and how people perceive it. The following definitions are applicable to the understanding of this analysis and the City of Vallejo’s noise standards. Equivalent Continuous 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. Maximum Noise Level (Lmax): the highest time-weighted sound level measured during a measurement period. Minimum Noise Level (Lmin): The lowest time-weighted sound level measured during a measurement period. Day-Night Noise Level (Ldn): the average A-weighted sound level during a 24-hour period with a 10-dB penalty applied during the sensitive nighttime hours of 10:00 p.m. to 7:00 a.m. Percentile-Exceeded Sound Level (Lx): Lx represents the sound level exceeded for a given percentage of a specified period (e.g., L10 is the sound level exceeded 10 percent of the time, and L90 is the sound level exceeded 90 percent of the time). Th City of Vallejo Municipal Code uses an L50 metric, explained in “Applicable Noise Standards.” Existing Noise Sensitive Land Uses
Noise-sensitive land uses are generally considered to include uses where noise exposure could result in health- related risks to individuals, as well as places where quiet is an essential element of their intended purpose, such as schools, libraries, and residences. Residential uses are of primary concern because of the potential for increased and prolonged exposure of individuals to both interior and exterior noise levels, and because these land uses are places of rest and sleep for City residents. The project site is located along Georgia Street, just west of the intersection with Sacramento Street. The nearest sensitive receiver to the project site is the Vallejo John F. Kennedy Library, located approximately 0.08 miles northwest of the project site, north of Georgia Street. There are multi-family residential dwellings along Maine Street, approximately 0.10 miles south of the project site.
Existing Noise Sources and Ambient Levels
The sound levels in most communities fluctuate, depending on the activity of nearby and distant noise sources, time of the day, or season of the year, with major roads and highways typically the primary sources of ambient noise in a community. Local roads closest to the project site include Georgia Street and Sacramento Street. The nearest major roadway to the project site is State Route (SR) 29, located approximately 0.18 miles east of the project site. The area surrounding the project site can be characterized as urbanized and developed, and includes commercial uses such as restaurants, banks, and the Vallejo Transit Center. Primary noise sources include roadway traffic noise (e.g., engine noise, car radios) and noise associated with the Greyhound Bus Station / Vallejo Transit Center (e.g., busses idling, people talking) on the south side of the project site.
To establish existing noise levels, an ambient noise survey was conducted on January 4 th and January 5th, 2024. One
long-term (LT) (24-hour) and three short-term (ST) (15-minute) measurements were conducted using a Piccolo II integrating sound level meter. The meter was calibrated before use with a Hangzhou Aihua Class 2 acoustical calibrator to ensure measurement accuracy. The measurement equipment meets all pertinent specifications of the American National Standards Institute. Meteorological conditions during the measurement period were adequate for reliable noise measurements, with clear skies, temperatures ranging from 43 degrees Fahrenheit (°F) to 57°F, and maximum windspeed of 7 miles per hour (mph), and no precipitation.
In accordance with Section 16.502.09.E of the City Code, the noise meter was located 5 feet above the ground and in no case was it within 10 feet of nearby walls or other structures that could affect noise measurements. On-site measurements were conducted for the purpose of established existing ambient noise levels for use in the noise compatibility assessment below. Noise levels are summarized below in Table 1 with corresponding labels indicating Final Noise and Vibration Study - Elite Charter School Project February 21, 2024

APPLICABLE NOISE STANDARDS
Federal
The Federal Transit Administration (FTA) developed the Transit Noise and Vibration Impact Assessment Manual, which provides guidance to engineers, planners, and consultants in assessing vibration from construction, operation, and maintenance of projects. To address the human response to ground vibration, the FTA has set forth guidelines for maximum-acceptable vibration criteria for different types of land uses. These guidelines are presented below in Table 2. In addition, FTA has also established construction vibration damage criteria, shown below in Table 3. Where local agencies have not adopted vibration criteria, as is the case in Vallejo, these criteria apply.

City of Vallejo Municipal Code
Section 16.502.03 Construction Management
The project site is in the City of Vallejo; therefore, the City’s local policies pertaining to noise are applicable to the project. City Code Section 16.502.03.C requires that all construction and transport equipment be muffled in accordance with State and federal laws. Section 16.502.03(E) mandates that grading and pile driving operations within Administrative Draft Noise and Vibration Study - Elite Charter School Project January 22, 2024
¼ mile of residential units be limited to the hours between 8:00 a.m. and 5:00 p.m. on weekdays to ensure compliance with the requirements for construction activity.
Section 16.502.09 Noise
Section 16.502.09 of the City Code provides maximum allowable noise standards for various land uses, which are the basis for this noise assessment. Per Section 16.502.09.C.2, the requirements impose limits on regularly occurring noise for the specified time periods, averaged over an hour. Table 16.502-C of the City Code (presented as Table 5 in this study) establishes daytime (7:00 a.m. to 10:00 p.m.) and nighttime (10:00 p.m. to 7:00 a.m.) noise standards applicable to various land uses, applicable on the subject property line, as well as noise limits at receiving residential zone boundaries.

THRESHOLDS OF SIGNFIICANCE
Based on the CEQA Appendix G Checklist and adopted City of Vallejo noise standards, the project would result in a significant impact to noise if it would result in:
Short-term construction noise levels that exceed 65 dBA Leq at Residential Medium Density, Residential High Density, Neighborhood Mixed Use, Neighborhood Commercial land uses during the daytime hours (i.e., 7:00 a.m. to 6:00 p.m. weekdays and 9:00 a.m. to 6:00 p.m. Saturdays); Short-term vibration levels that result in disturbance to sensitive uses or the potential to cause structural damage to structures;
Operational stationary noise levels that exceed 65 dBA Leq at residential uses; or Operational mobile noise sources that result in a substantial (i.e., 5 dBA) increase in noise.
ANALYSIS
Potential to Result in Substantial Temporary (Construction) Noise Short-term construction noise levels would fluctuate depending on the type, number, and duration of usage of varying equipment. Additionally, the effects of construction noise largely depend on the type of construction activities being performed; noise levels generated by those activities; distances to noise-sensitive receptors; the relative locations of noise attenuating features such as topography and existing structures; and existing ambient noise levels.
The proposed project would not require the demolition of the existing building. The project would include internal improvements to reconfigure the space for classrooms, administrative offices, and other education-related amenities.
Both phases of development would include various onsite improvements and upgrades to the existing buildings, including the installation of wrought iron fencing; removal of shrubs and trees; construction of curbs, ramps, and gutters; trenching for underground utilities; removal/reconfiguration of existing paved areas (e.g., curb and sidewalk portions) to accommodate reconfigured street parking; and construction of a new accessible ramp that would connect Sacramento Street to the rear entrance of the building. Construction equipment associated with these activities could include dump trucks, concrete mixers, pickup trucks, chainsaws, and concrete saws. Based on reference noise levels for typical construction equipment, the demolition/removal of existing concrete using concrete Administrative Draft Noise and Vibration Study - Elite Charter School Project January 22, 2024
saws would represent the loudest phases of construction. Thus, the noise assessment is based on this phase as all subsequent phases and associated noise levels would be lower than this activity.
As shown above in Table 7, the City of Vallejo identifies one set of standards for mobile construction equipment and one set of standards for stationary equipment. Both mobile (e.g., dump trucks and pickup trucks) and stationary equipment (e.g., concrete saws) could be used in project construction. The project site is located within a mixed-use zoning area, and thus, although downtown mixed-use is not specifically included in Table 7, the standards that apply for other mixed-use areas included in the table (i.e., neighborhood mixed use) are used in this analysis (i.e., 65 dBA) and are applied as hourly averages (i.e., L
eq).
Modeling identified that the operation of a concrete saw would result in noise levels of 83.0 dBA Leq at 50 feet. See Attachment A for modeling inputs and results. Such activity would reduce to the City’s construction noise standard of 65 dBA Leq for mixed-use areas at 398 feet. There are no sensitive receptors located within this distance. The sensitive receptor nearest to Georgia Street, where this modeling scenario would occur, is the Vallejo John F. Kennedy Library located approximately 400 feet northwest of the project site. At this distance, noise levels would attenuate to 64.9 dBA Leq, and therefore would not exceed applicable City standards. The nearest residential receptors are located approximately 494 feet south of the project site. At this distance, noise levels from the use of a concrete saw would attenuate to 63.1 dBA Leq, and therefore would not exceed applicable City standards.
Based on the modeling conducted for the worst-case construction phase, project construction noise would not conflict with City standards. Further, construction activity and resulting noise would be temporary in nature, with an anticipated 8-month duration for each phase of the project and would end once construction is complete. During this time, construction activities would occur between 7:00 a.m. and 3:00 p.m., as no nighttime construction work is proposed. For these reasons, the noisiest construction equipment would not generate significant levels of noise that exceed adopted noise standards and would not substantially affect nearby receptors.
Potential Construction Vibration
Project construction would not involve the use of ground vibration-intensive activities, such as pile driving or blasting.
The pieces of construction equipment that would be used during project construction, such as concrete saws and light trucks, generate little to no ground vibration and are not considered impact devices (FHWA 2006). Construction activity would be intermittent and temporary and is estimated to take approximately eight months for each phase.
Specifically, construction activities associated with the project would occur during daytime hours (i.e., between 7:00 a.m. and 3:00 p.m.). Therefore, any vibration activity that would result from project construction would not occur during evening or nighttime hours, thereby reducing potential vibration impacts (i.e., annoyance) to nearby receptors during more sensitive hours of the day. Additionally, the project would not involve the development of any major sources of ground vibration such as commercial railways or passenger rail transit lines. Therefore, the project would not result in long-term operational activities associated with permanent or substantial levels of ground vibration. For these reasons, construction and operational generated vibration would not result in the potential for structural damage or human annoyance.
Operational Stationary Noise
Mechanical Equipment Noise
The project would include mechanical building equipment as part of the heating, ventilation, and air conditioning (HVAC) systems at the project site. HVAC equipment is a common noise source associated with land use development and is currently used on the project site. Specifically, there are currently 20 air conditioning units and three mechanical fans on the building rooftop. Therefore, noise associated with the mechanical equipment would not represent a new noise source in the area. Implementation of the project would result in the removal of 20 air conditioning units and three mechanical fans, as well as the installation of 14 new air conditioning units and five new mechanical fans. Therefore, the project would include fewer pieces of mechanical equipment than previously located Administrative Draft Noise and Vibration Study - Elite Charter School Project January 22, 2024
on the site. Further, as the school would generally operate during the daytime hours (i.e., between 9:00 a.m. and 3:00 p.m.), noise associated with building equipment would not result in substantial increases during sensitive times of the day. For these reasons, building equipment noise would not result in adverse effects to nearby sensitive receptors.
Outdoor Common Areas
The project would include the addition of outdoor common areas along Georgia Street that would be in use during daytime school hours. The addition of the outdoor patio could result in an increase in localized noise on the project site associated with people talking, congregating, and eating outdoors. Noise associated with people talking and eating would not be unique, dissimilar, or louder than existing ambient noise levels associated with urban environments (e.g., roadway traffic, people talking, landscape equipment). Additionally, the outdoor areas would be in use for short periods of time during daytime hours (i.e., weekdays between 9:00 a.m. and 3:00 p.m.) and would not be operational during nighttime hours and would not emit nighttime noise. For these reasons, noise from outdoor common areas would not result in adverse effects to nearby sensitive receptors.
Loading and Unloading
The operation of the new school would require daily delivery of food for students. Food delivery would take place Monday through Friday from 8:00 a.m. to 9:00 a.m. and from 11:00 a.m. to 1:00 p.m. As shown in the site plans, the deliveries would take place in the designated loading/unloading area along Sacramento Street, on the eastern frontage of the project site. Noise sources from truck activity associated with delivery areas are usually short-term and can include activities such as vehicle idling, engine revving, and the release of air brakes on heavy trucks. Based on a noise measurement conducted by Ascent on April 20, 2023, at the loading and unloading dock at an Anheuser Bush facility, noise from truck activity can be as loud as 59 dBA L eq at 100 feet (Ascent 2023). The off-site residential
receptor closest to the on-site delivery area are the multi-family residences located along Maine Street, approximately 494 feet south of the project site. Delivery truck-generated noise would be 45.1 dBA Leq at 494 feet.
Therefore, delivery truck noise would not exceed the City’s daytime noise standards of 65 dBA Leq.
Summary
Project operation would result in new stationary noise sources such as noise associated with HVAC equipment, outdoor common areas, and food delivery activity. Noise levels from new and existing noise sources would not exceed applicable daytime exterior noise standards established by the City. Further, as described in detail above, none of these sources would operate during the nighttime because the school would be closed by 3:00 p.m. daily, with limited after-school, evening, or weekend activities. Thus, project-generated noise would not result in any exceedance of nighttime noise standards.
Operational Mobile Source Noise
Vehicle trips associated with the project would include trips generated by employees and students. These trips would result in an increase in average daily traffic volumes and associated increase in traffic noise levels along roadway segments that would be used to travel to and from the project site. To analyze the impact of project-generated operational transportation noise sources, traffic noise levels under existing and existing-plus-project conditions were modeled for affected roadway segments. Refer to Attachment A for detailed noise modeling input parameters.
Due to the logarithmic properties of noise, a 3 dB increase in noise is characterized as barely perceptible, a 5 dB increase as distinctly perceptible, and a 10 dB increase as a doubling of the noise level. Further, it requires a doubling of the noise source to result in an audible (i.e., 3 dB) increase. Thus, a perceptible increase in noise (i.e., 5 dB), would be considered a substantial increase in noise. It should be noted that potential trip reductions from the student survey were not accounted for in this analysis, resulting in a conservative roadway analysis. Table 8 shows the existing and existing plus project noise levels of the roadway segments nearest to the project site.

As shown in Table 8, implementation of the project would result in noise increases ranging from 0.1 dBA to 3.4 dBA Ldn on roadway segments within the project vicinity. The project would not result in a substantial noise increase (i.e., 5 dB or more) compared to existing conditions. All roadways currently experience noise levels below the “Normally Acceptable” levels applicable to the project area (i.e, 60 dBA Ldn for single-family residential, 65 dBA Ldn for residential multi-family and 75 dBA Ldn for nonresidential uses) and the project would not result increases in noise that exceed these levels along modeled roadway segments. Long-term operational noise from the project would not result in substantial increases in noise or levels that exceed applicable City standards.
Exposure to Existing Community Noise
As discussed above, the Vallejo General Plan establishes guidelines for noise exposure to new development based on the specific land use. Based on the land use categories established in Table NBE-1 (presented as Table 4 in this study) of the General Plan, new schools are subject to existing noise exposure levels of up to 70 dBA Ldn. As shown above in Table 1, an existing 24-hour noise measurement was conducted on January 4, 2024 and using the individual Leq data for each hour of the 24-hour period, a 24-hour Ldn was calculated of 65.5 dBA, which is below the level identified by the City of Vallejo as normally acceptable for school uses (i.e., 70 dBA Ldn). The proposed school would not be exposed to noise levels exceeding City of Vallejo’s adopted noise exposure levels.
CONCLUSION
Project-generated construction noise would be short-term and temporary and would comply with the City of Vallejo’s construction noise standards and would not expose sensitive land uses to excessive noise. The project would not result in operational sources of substantial vibration. Project construction would not require the use of vibration- inducing equipment such as pile drivers and all construction would occur during the less sensitive daytime hours when people are awake thereby reducing the exposure of sensitive receptors to substantial vibration levels.
Operational stationary noise sources would not result in new substantial sources of noise to the project area or exceed applicably City standards. Operational increases in noise levels from vehicle trips would not result in a substantial increase in noise over existing conditions. Therefore, project related construction and operational noise and vibration would not be expected to exceed federal, state, or local standards or expose sensitive land uses to substantial increases in noise or vibration levels. Thus, approval of the project would not result in a significant effect related to noise.

Notes:
Sources:
Computation of the ground factor is based on the equation presentd in Table 4-26 on pg. 86 of FTA 2018, where the distance of the reference noise leve can be adjusted and the usage factor is not applied (i.e., the usage factor is equal to 1).

<http://www.transit.dot.gov/sites/fta.dot.gov/files/docs/research-innovation/118131/transit-noise-and-vibration-impact-assessment-manual-fta-report- STEP 1: Identify the noise source and enter
the reference noise level (dBA and distance).
STEP 2: Select the ground type (hard or soft),
and enter the source and receiver heights.
STEP 3: Select the distance to the
receiver.
Estimates of attenuated noise levels do not account for reductions from intervening barriers, including walls, trees, vegetation, or structures of any type.
Computation of the attenuated noise level is based on the equation presented on pg. 176 and 177 of FTA 2018.

Date: February 21, 2024
To: Christina Ratcliffe, Planning and Development Services Director, City of Vallejo CC: Erwin Ordonez, Interwest
From: Alta Cunningham, M.A. Historic Preservation, Dimitri Antoniou, Ascent Environmental Subject: Historical Resources Study - 241-255 Georgia Street in Vallejo, CA Class 32 Exemption
INTRODUCTION AND PURPOSE
Ascent Environmental has been retained to prepare technical memos in support of a California Environmental Quality Act (CEQA) Class 32 Categorical Exemption for the Elite Charter School Project, (project), located in the City of Vallejo, California. Section 15332 of the State CEQA Guidelines allows for the use of a categorical exemption for infill development, provided the contemplated development meets certain criteria, and that none of the exceptions to the exemptions apply (CEQA Guidelines Section 15300.2). This includes not causing a substantial adverse change in the significance of a historical resource; this includes both built environment features and archaeological sites. This memo addresses the project’s potential to affect historical resources.
PROJECT DESCRIPTION AND ENVIRONMENTAL SETTING
The project site is located at 241-255 Georgia Street on Assessor’s Parcel Number (APN) 0055-170-390 in Vallejo, California. The project site is bounded by an existing commercial development to the west, Georgia Street to the north, Sacramento Street to the east, and an existing parking lot and Vallejo Transit Center to the south. The project site is currently occupied by a two-story building.
The proposed project would provide a new public charter high school that would accommodate a maximum of 400 students and 35 staff. The proposed project would be completed in phases as the school continues to grow enrollment and additional funds for construction become available. The existing structure would not be demolished but internal improvements would be made to reconfigure the building layout. The initial development phase proposes to develop approximately 18,000 square feet of interior space suitable for 13 classrooms, four offices, bathroom facilities, a serving kitchen, a multi-purpose room, a library alcove, and a future gymnasium on the ground floor. The second development phase proposes to develop five additional classrooms, storage areas, restrooms, a conference room, and four private offices on the second floor. The proposed project would also include development of perimeter fencing for security purposes, school signage, the reconfiguration of 16 parking spaces into eight parking spaces along Sacramento Street, as well as the addition of 36 bicycle parking spaces. The proposed project improvements would be ADA accessible and comply with State design and construction standards.
Final Historical Resources Study - 241-255 Georgia Street February 21. 2024
REGULATIONS PERTAINING TO HISTORICAL RESOURCES
California Environmental Quality Act
CEQA requires public agencies to consider the effects of their actions on “historical resources.” Pursuant to Public Resources Code (PRC) Section 21084.1, a “project that may cause a substantial adverse change in the significance of an historical resource is a project that may have a significant effect on the environment.” “Historical resource” is a term with a defined statutory meaning (PRC Section 21084.1; State CEQA Guidelines Sections 15064.5[a] and [b]).
Under State CEQA Guidelines Section 15064.5(a), historical resources include the following:
1) A resource listed in, or determined to be eligible by the State Historical Resources Commission for listing in, the CRHR (PRC Section 5024.1).
2) A resource included in a local register of historical resources, as defined in PRC Section 5020.1(k) or identified as significant in a historical resource survey meeting the requirements of PRC Section 5024.1(g), will be presumed to be historically or culturally significant. Public agencies must treat any such resource as significant unless the preponderance of evidence demonstrates that it is not historically or culturally significant. 3) Any object, building, structure, site, area, place, record, or manuscript that a lead agency determines to be historically significant or significant in the architectural, engineering, scientific, economic, agricultural, educational, social, political, military, or cultural annals of California may be considered to be a historical resource, provided the lead agency’s determination is supported by substantial evidence in light of the whole record. Generally, a resource will be considered by the lead agency to be historically significant if the resource meets the criteria for listing in the CRHR (PRC Section 5024.1).
4) The fact that a resource is not listed in or determined to be eligible for listing in the CRHR, not included in a local register of historical resources (pursuant to PRC Section 5020.1[k]), or identified in a historical resources survey (meeting the criteria in PRC Section 5024.1[g]) does not preclude a lead agency from determining that the resource may be a historical resource as defined in PRC Sections 5020.1(j) or 5024.1.
California Register of Historical Resources
The CRHR is a listing of State of California resources that are significant in the context of California’s history. Resources listed in the National Register of Historic Places (NRHP) is automatically listed in the CRHR. A historical resource must be significant at the local, state, or national level under one or more of the criteria defined in the California Code of Regulations Title 15, Chapter 11.5, Section 4850 to be included in the CRHR. The CRHR criteria are tied to CEQA because any resource that meets the criteria below is considered a significant historical resource under CEQA.
The CRHR uses four evaluation criteria:
Criterion 1. Is associated with events that have made a significant contribution to the broad patterns of local or regional history, or the cultural heritage of California or the United States.
Criterion 2. Is associated with the lives of persons important to local, California, or national history.
Criterion 3. Embodies the distinctive characteristics of a type, period, region, or method of construction; represents the work of a master; or possesses high artistic values.
Criterion 4. Has yielded, or has the potential to yield, information important to the prehistory or history of the local area, California, or the nation.
A historical resource must meet one of the above criteria and retain integrity to be listed in the CRHR. For a property to retain and convey historic integrity it must possess most of the seven aspects of integrity: location, design, setting, materials, workmanship, feeling, and association. Location is the place where the historic property was constructed or the place where a historic event occurred. Integrity of location refers to whether the property has been moved since Final Historical Resources Study - 241-255 Georgia Street February 21. 2024
its construction. Design is the combination of elements that create the form, plan, space, structure, and style of a property. Setting is the physical environment of a historic property that illustrates the character of the place. Materials are the physical elements that were combined or deposited during a particular period of time and in a particular pattern or configuration to form a historic property. Workmanship is the physical evidence of the crafts of a particular culture or people during any given period in history or prehistory. Feeling is a property’s expression of the aesthetic or historic sense of a particular period of time. This is an intangible quality evoked by physical features that reflect a sense of a past time and place. Association is the direct link between the important historic event or person and a historic property. Continuation of historic use and occupation help maintain integrity of association.
City of Vallejo Municipal Code
Chapter 2.48 of the City of Vallejo Municipal Code establishes the Architectural Heritage and Landmarks Commission, a seven-member group appointed by the City Council. The Commission is charged with:
Conducting design review and holding public hearings for restoration, remodeling, demolition, and development projects, which take place within the city's designated historic districts, or which affect city landmarks, using the standards of the Secretary of Interior’s Standards for the Treatment of Historic Properties or City policy as criteria for determining the historic and aesthetic appropriateness of proposed improvements. Surveying the older buildings and neighborhoods to identify those structures which have historic and/or architectural significance, and designating buildings, sites and objects of particular historic or architectural significance as City landmarks.
Making policy recommendations to the City Council on matters which relate to historic preservation and the restoration of the designed districts.
Chapter 16.38 of the Municipal Code codifies the City's goals and policies regarding historic preservation. The purpose of the Architectural Heritage and Historic Preservation Ordinance is to:
Designate, preserve, protect, enhance and perpetuate those historic buildings, structures, landscaping, districts and neighborhoods which contribute to the cultural and aesthetic heritage of Vallejo. Foster civic pride in the beauty and accomplishments of the past. Stabilize and improve the economic values of certain historic buildings, structures, landscaping, districts and neighborhoods.
Protect and enhance the city's cultural and aesthetic heritage. Recognize the uniqueness of historic resources on Mare Island that have contributed to the history of Vallejo, California and the United States and that have significant value to the economic development and land use goals for the island and the community.
Promote and encourage continued private ownership, where appropriate, and utilization of such buildings and other structures now so owned and used, to the extent that the objectives listed above can be obtained under such policy.
Structures, objects, and areas in Vallejo having special historical, cultural, architectural or aesthetic interest or value may be classified as one of the following (16.38.160):
City Landmark. City landmarks shall include those structures found to have unique historical, architectural or aesthetic interest or value and which are eligible for or listed on the National Register of Historic Places. Historic Structure. Historic structures shall include those structures found to have outstanding historical, architectural or aesthetic interest or value.
Final Historical Resources Study - 241-255 Georgia Street February 21. 2024
Structure of Merit. Structures of merit shall include those structures found to have significant historical, architectural or aesthetic interest or value.
Contributing Structure. Contributing structures shall include those structures found to warrant special historical, architectural or aesthetic interest or value.
Designation of a resource as a City landmark, historic structure, structure of merit, or contributing structure is based on the following criteria (16.38.150):
Architectural Merit:
Property that is the first, last, only, or most significant architectural property of its type in the city or region. Property that is the prototype of, or outstanding example of, periods, styles, architectural movements, engineering or construction techniques, or an example of the more notable work, or of the best surviving work in the city or region of an architect, designer or master builder. Architectural examples worth preserving for the values they add when integrated into the total fabric of the city's neighborhoods.
Cultural Value: Structures, objects, sites and areas associated with the movement or evolution or religious, cultural, governmental, social and economic developments of the city; Educational Value: Structures worth preserving for their educational value; Historical Value:
Preservation and enhancement of structures, objects, sites and areas that embody and express the history of Vallejo, Solano County, California, or the United States. History may be social, cultural, economic, political, religious or military; Any property which is listed in the National Register of Historic Places and as described in Section 470a of Title 16 of the United States Code and/or is a registered state landmark.
EXEMPTIONS UNDER CEQA
Section 15332 of the CEQA Guidelines allows for the use of a Class 32 Categorical Exemption, provided the contemplated development meets certain criteria:
(a) The project is consistent with the applicable general plan designation and all applicable general plan policies as well as with applicable zoning designation and regulations. (b) The proposed development occurs within city limits on a project site of no more than five acres substantially surrounded by urban uses.
(c) The project site has no value as habitat for endangered, rare or threatened species. (d) Approval of the project would not result in any significant effects relating to traffic, noise, air quality, or water quality.
(e) The site can be adequately served by all required utilities and public services.
Final Historical Resources Study - 241-255 Georgia Street February 21. 2024
A lead agency must also consider whether a project may fall under a list of exceptions to all classes of exemptions, as detailed under Section 15300.2 of the CEQA Guidelines:
(a) Location. Classes 3, 4, 5, 6, and 11 are qualified by consideration of where the project is to be located -a project that is ordinarily insignificant in its impact on the environment may in a particularly sensitive environment be significant. Therefore, these classes are considered to apply in all instances, except where the project may impact on an environmental resource of hazardous or critical concern where designated, precisely mapped, and officially adopted pursuant to law by federal, state, or local agencies. (b) Cumulative Impact. All exemptions for these classes are inapplicable when the cumulative impact of successive projects of the same type in the same place, over time is significant. (c) Significant Effect. A categorical exemption shall not be used for an activity where there is a reasonable possibility that the activity will have a significant effect on the environment due to unusual circumstances. (d) Scenic Highways. A categorical exemption shall not be used for a project which may result in damage to scenic resources, including but not limited to, trees, historic buildings, rock outcroppings, or similar resources, within a highway officially designated as a state scenic highway. This does not apply to improvements which are required as mitigation by an adopted negative declaration or certified EIR. (e) Hazardous Waste Sites. A categorical exemption shall not be used for a project located on a site which is included on any list compiled pursuant to Section 65962.5 of the Government Code. (f) Historical Resources. A categorical exemption shall not be used for a project which may cause a substantial adverse change in the significance of a historical resource.
ANALYSIS
On January 18, 2024, a records search of the project site and a 0.25-mile buffer was conducted at the Northwest Information Center (NWIC), at Sonoma State University (NWIC File No.: 23-0811; Attachment A). The following information was reviewed as part of the records search:
NRHP and CRHR,
Historic Property Data File for Marin County,
Archaeological Determinations of Eligibility,
California Inventory of Historic Resources,
California State Historic Landmarks,
California Points of Historical Interest, and
Historical GLO land plat maps.
The results of the records search review revealed that two previous studies of cultural resources have been conducted within the project site and that an additional five cultural resources studies have been completed for lands within a
0.25-mile radius. The two studies that cover the project site were conducted between 2000 and 2010; both address archaeological and built-environment topics and included subsurface testing. The reports conclude that there is potential to encounter subsurface historic-era archaeological deposits (e.g., bottles, refuse, building foundations), however, the potential for pre-contact archaeological deposits (e.g., lithics, stone tools, shells, beads) was low due to the location of the project site being in an upland area away from fresh water sources and exposed to the wind (Beard 2008; Chattan 2004).
Final Historical Resources Study - 241-255 Georgia Street February 21. 2024
The NWIC records search also revealed that no built environment features or archaeological sites have been previously recorded within the project site. One archaeological site and two built environment features were identified within the 0.25-mile radius.
Additionally, the project site is located south of the NRHP-listed Saint Vincent's Hill Historic District and west of the NRHP-listed Architectural Heritage District. The building is not listed as a City of Vallejo Landmark (City of Vallejo 2016:
4.4-8 through 4.4-14). Although the building has not been evaluated for CRHR-eligibility, it is possible that it could be recommended eligible later. As described above, eligibility rests on twin factors of significance and integrity. The project does not have the potential to result in adverse changes to the integrity of the building, such as would render it ineligible for listing. The project does not include demolishing the existing structure or altering external features of the building. ADA improvements, changes to the parking layout, perimeter fencing, and internal design changes would not affect integrity of location, design, setting, materials, workmanship, feeling, or association, as described above.
CONCLUSION
The building at 241-255 Georgia Street is not listed on the CRHR or as a City of Vallejo Landmark. The project does not have the potential to cause a substantial adverse change in the significance of a historical resource if the building was ever recommended eligible for listing as either a landmark or CRHR.
There are no known archeological or tribal cultural resources on the site that qualify as historical resources, according to readily available material. Given that the property has been previously disturbed, the likelihood of finding such resources intact and within their relevant historic context is relatively low. Although not required to support an infill exemption or an SB 330 application, the project would comply with Public Resources Code and Health and Safety Code requirements that protect unanticipated cultural discoveries.
Public Resources Code section 21083.2 requires that if a unique archaeological resource is discovered, reasonable efforts be made to permit any or all of these resources to be preserved in place or left in an undisturbed state.
Examples of appropriate treatment, in no order of preference, may include, but are not limited to, the following:
Planning construction to avoid archaeological sites.
Deeding archaeological sites into permanent conservation easements. Capping or covering archaeological sites with a layer of soil before building on the sites. Planning parks, greenspace, or other open space to incorporate archaeological sites.
To the extent that unique archaeological resources are discovered and preservation in place is not feasible, an archeologist would determine an appropriate treatment plan, which could include excavation.
Health & Safety Code section 7050.5 states:
In the event of discovery or recognition of any human remains in any location other than a dedicated cemetery, there shall be no further excavation or disturbance of the site or any nearby area reasonably suspected to overlie adjacent remains until the coroner of the county in which the human remains are discovered has determined, in accordance with Chapter 10 (commencing with Section 27460) of Part 3 of Division 2 of Title 3 of the Government Code, that the remains are not subject to the provisions of Section 27491 of the Government Code or any other related provisions of law concerning investigation of the circumstances, manner and cause of any death, and the recommendations concerning the treatment and disposition of the human remains have been made to the person responsible for the excavation, or to his or her authorized representative, in the manner provided in Section 5097.98 of the Public Resources Code. The coroner shall make his or her determination within two working days from the time the person responsible for the excavation, or his or her authorized representative, notifies the coroner of the discovery or recognition of the human remains. If the coroner determines that the Final Historical Resources Study - 241-255 Georgia Street February 21. 2024
remains are not subject to his or her authority and if the coroner recognizes the human remains to be those of a Native American, or has reason to believe that they are those of a Native American, he or she shall contact, by telephone within 24 hours, the Native American Heritage Commission.
Public Resources Code section 5097.98 sets for the requirements for the NAHC when it receives notice from the coroner of the discovery of Native American human remains. It also includes requirements for the landowner, which include:
Upon the discovery of the Native American remains, the landowner shall ensure that the immediate vicinity, according to generally accepted cultural or archaeological standards or practices, where the Native American human remains are located, is not damaged or disturbed by further development activity until the landowner has discussed and conferred, as prescribed in this section, with the most likely descendants regarding their recommendations, if applicable, taking into account the possibility of multiple human remains. The landowner shall discuss and confer with the descendants all reasonable options regarding the descendants’ preferences for treatment.
The above existing laws, which the project applicant must follow in accordance with standard conditions of approval, would prevent significant impacts from project construction on unique archeological resources and human remains.
Therefore, the project would not result in any impacts to historical resources, and this exception to the exemption in Section 15332 does not apply.

II. CALIFORNIA ENVIRONMENTAL QUALITY ACT FINDING
Following a review of the project, the Planning Commission has determined that it is exempt from the California Environmental Quality Act (CEQA) requirements. The project is exempt from environmental review under the California Environmental Quality Act (CEQA) pursuant to CEQA Guidelines Section 15332 (Class 32: In-fill Projects) because the project is on a site of less than 5 acres within city limits surrounded by urban uses, is consistent with the applicable general plan designation and all applicable general plan policies as well as with the applicable zoning designation and regulations, has no value as habitat for endangered, rare or threatened species, is adequately served by all required utilities and public services, and approval of the project would not result in any significant effects relating to traffic, noise, air quality, or water quality. Further, none of the exceptions pursuant to Section 15300.2 of the CEQA Guidelines apply, in that
a. The project is located on an in-fill site and there are no environmental resource of hazardous or critical concern where designated, precisely mapped, and officially adopted pursuant to law by federal, state, or local agencies; and b. There is no cumulative impact in that this is the only type of this use in this area; and
c. There is no reasonable possibility that the renovation of an empty office building will have a significant effect on the environment as there are no unusual circumstances associated with this downtown in-fill site; and d. There will be no damage to scenic resources, including but not limited to, trees, historic buildings, rock outcroppings, or similar resources, within a highway officially designated as a state scenic highway, as the location is not near a scenic highway.
III. FINDINGS RELEVANT TO THE APPROVAL OF THE MAJOR USE PERMIT
Vallejo Municipal Code (VMC) Section 16.606.03 requires the review authority to make the following findings prior to granting a Major Use Permit. the findings are in bold, and staff’s determination follows in italics.
A. The proposed use is conditionally allowed within the applicable zoning district and complies with all other applicable provisions of the Zoning Code and all other titles of the Vallejo Municipal Code.
The proposed project is located on a property zoned Downtown Mixed Use (DMX). Vallejo Municipal Code Table 16.301-A: Land Use Regulations, requires a Major Use Permit for a school more than 10,000 square feet. The project is consistent with the applicable development standards outlined in Title 16 of the VMC, as proposed and conditioned.
B. The proposed use is consistent with the general plan and any applicable specific plan or planned development and any other applicable plans.
The project site is designated as District – Downtown Waterfront (D-D/W) on the General Plan Land Use Map. It is intended to promote a vibrant, pedestrian‐oriented place that seamlessly integrates downtown with the waterfront. Layering compatible land uses and public amenities, together at various scales and intensities, the D‐D/W designation allows for multiple functions within the same building or adjacent to one another in the same general vicinity to foster a mix of uses that encourages people to live, work, play, and shop in close proximity. The D‐D/W designation is also intended to create a vibrant destination DocuSign Envelope ID: BCF4876B-A0B9-4747-A53C-CA9D19C1F1B4
for people from other parts of the city and the region. The project as proposed and conditioned adds 400 students and support staff to the Downtown area in an existing building that has remained vacant for years. This will also bring parents into the downtown and help to activate economic vitality to the Downtown. The project is also consistent with applicable General Plan 2040 policies as noted above in the report.
C. The subject parcel is physically suitable for the type of land use being proposed.
The public charter high school is proposing to renovate and occupy a vacant two-story office building in the Downtown area. No major exterior alterations are proposed for the exterior design of the building. The subject parcel is physically suitable for the proposed use because most activities associated with the school use will occur indoors, the applicant has agreed to incorporate changes to their proposed operational plans and procedures and will construct off-site public improvements to ensure that the proposed use will not create negative impacts on the surrounding properties. These plans and procedures are included as Conditions of Approval. The applicant is proposing to satisfy recreational needs of students with staggered scheduling in the interior recreation areas.
D. The proposed use is compatible with existing and permissible land uses within the zoning district and the general area in which the proposed use is to be located which may include but not be limited to size, intensity, hours of operation, number of employees, or the nature of the operation.
The proposed project is compatible with existing and permissible land uses within the zoning district. A similar educational use is located immediately across Georgia Street from the project site, the use will activate a vacant commercial building and includes site improvements to ensure compatibility with surrounding uses. The proposed use plans to operate between the hours of 8:00 a.m. to 3:30 p.m. Monday-Friday with occasional after- school events and activities. Conditions of approval have been added to reflect these hours and reasonable limitations.
E. The physical location or placement of the use on the site is compatible with and will not adversely affect the livability or appropriate development of abutting properties and the surrounding neighborhood.
The physical location of the proposed project inside an existing vacant office building will not adversely affect the livability or appropriate development of abutting properties and the surrounding neighborhood. Conditions of approval have been added to address vehicle queuing during drop-off and pick up hours.
F. The proposed use and related project features will not create any nuisances arising from the emission of odor, dust, gas, noise, vibration, smoke, heat or glare at a level exceeding ambient conditions and would not otherwise be detrimental to the public interest, health, safety, or general welfare.
As proposed and conditioned, the public charter high school will not create any nuisances from odors, dust, gas, noise, vibration, smoke, heat or glare exceeding ambient conditions.
As proposed and conditioned, the use will not be detrimental to the public interest, health, safety, or general welfare.
G. The project has been reviewed in compliance with the California Environmental Quality Act, if applicable, and the requirements of this chapter.
Following a review of the project, staff is recommending that the Planning Commission find the project categorically exempt from the requirements of the California Environmental DocuSign Envelope ID: BCF4876B-A0B9-4747-A53C-CA9D19C1F1B4
Quality Act (CEQA), pursuant to Section 15332, Class 32, In-fill Projects. Staff required studies that support this exemption, which is discussed in more detail, below.
IV. DETERMINATIONS RELEVANT TO THE APPROVAL OF ESTABLISHMENT
OF A SCHOOL IN ALL OR PART OF AN EXISTING BUILDING THAT WAS NOT DESIGNED FOR OR OCCUPIED BY A K-12 SCHOOL
VMC Section 16.335.02 A 3 requires the review authority to make the following determinations to grant a Use Permit (the determinations are in bold, and staff’s determination follows in italics):
a. The school location is appropriate for the use, and that adjacent uses will not be adversely affected.
The school location is appropriate for the use, and adjacent uses will not be adversely affected in that a similar and complimentary educational use is located across Georgia Street from the site and students also have easy access to the John F. Kennedy library.
In addition, the school would bring staff, students and parents into the downtown area increasing pedestrian traffic to restaurants and shops.
b. Adequate access, student drop-off areas and required off-street parking is provided.
Under VMC section 16.508.04 A, no parking is required for this site; however, on-street public parking is available on Georgia and Sacramento Streets. Additional parking to support the school and other nearby uses is available in the Downtown Parking District parking lots via parking passes which can be purchased. The applicant is proposing drop-off zones along the curbline of the Georgia and Sacramento Streets during the morning and afternoon which will temporarily reduce the availability of the on-street parallel spaces during this period. Sixteen (16) diagonal spaces on Sacramento Street will be permanently converted into 8 parallel spaces. In addition, the site is adjacent to the Vallejo Transit Hub, and has easy walking or biking via the Class III bike lanes. The applicant is providing bike racks for 38 bikes.
c. Outdoor play areas are appropriately-sized, furnished with facilities and equipment, safe, and secure.
N/A. While indoor PE areas are provided, there are no outdoor facilities.
V. RESOLUTION APPROVING THE PROJECT AT 241-255 GEORGIA STREET NOW, THEREFORE, LET IT BE RESOLVED that the Planning Commission hereby APPROVES, Major Use Permit (UP22-0008) and affirming that the project is exempt from environmental review under the California Environmental Quality Act (CEQA) pursuant to CEQA Guidelines Section 15332 (Class 32: In-fill Projects), based on the above findings and subject to the Conditions of Approval attached to this Resolution.
