SUMMARY: The Applicant, Fire Station Properties LLC, represented by David Lang, filed an application for Site and Architectural Review 23-23. The Applicant proposes the development of a 12,406-square foot dental office building on a 1.67-acre site located at the northeast corner of Mount Vernon Avenue and City Center Court (APNs: 1178-01- 109,1178-01-110, and 1178-01-111). Additionally, the Applicant will be processing a Lot Merger Application (LM 24-01) ministerially through City Engineering and Planning to combine all three lots into a single property. Site improvements include, but are not limited to, landscaping, parking lot, parking lot lighting, streetlights, roofed trash enclosure, generator enclosure, solar canopy for cars, bicycle rack, and art area. The Project site is zoned The Barton Road Specific Plan (BRSP) Village Commercial (VC) Planning Area 2 (P.A.2.). The dental office land use is permitted in the Village Commercial (VC) and does not require a Conditional Use Permit. The Applicant has provided an in-depth letter of intent that is provided as Attachment 3 to this agenda staff report. BACKGROUND: Spring Hills Family Dentistry is an existing Grand Terrace business that has been operating for many years from the dental office building at 22737 Barton Road, Grand Terrace, CA. The new two-story 12,406 square foot dental office building will be twice the size of the current office and is only a quarter mile distance from the current Spring Hills Family Dentistry at 22737 Barton Road. The Project site is located at the northeast corner of Mount Vernon Avenue and City Center Court. The site is adjacent to an existing two-story office building to the north, fire station to the east and public rights-of- ways to the west (Mount Vernon Avenue) and south (City Center Court). The project site is approximately 1.67 acres and is composed of three separate parcels. All three are done ministerially. The site is relatively flat with no cultural, historical, or scenic aspects. imagery shows that at one time residential dwellings on the Project site that fronted Mount Vernon Avenue that were removed when City Center Court and the fire station were constructed on or about 1983. The Project site includes an easement for drainage that runs along the northern property line. The City Engineer and Planning Staff worked closely with the Applicant to adjust the site plan so that no structures are within said easement. The only use of the site in recent years has been the sand mound supplied by the City for sand bagging in times of inclement weather. The sandbag supply will be repositioned to the City Hall parking lot going forward. ANALYSIS: Packet Pg. 10 B.1 The objective of the Barton Road Specific Plan (BRSP) is to assure the systematic implementation of the General Plan within the Barton Road Specific Plan (BRSP) using a comprehensive plan of land use, development regulations, design guidelines, development incentives and other related action aimed at implementing the goals and objectives set forth in the Barton Road Specific Plan (BRSP). The Barton Road Specific Plan (BRSP) is the regulatory plan that serves as zoning law for all properties located within the boundaries of the Barton Road Specific Plan (BRSP). All discretionary development, such as the Spring Hills Family Dentistry office building, must be consistent with the Specific Plan. The first preliminary review for compliance of any went to a DAB meeting in April of 2023. The purpose of the DAB meeting is for all key City Departments and utility agencies to coordinate at the early stages of design with the Applicant and to provide feedback. The Applicant took the feedback from the DAB and incorporated it into their design that was submitted in October of 2023. After a round of review for completeness the project was determined to be sufficient to notice for Public Hearing before the Planning Commission. The sections below include an analysis of key aspects of the proposed development. Site Plan: Access to the site will be solely from two driveways along City Center Court. The existing two driveway aprons located along Mount Vernon Avenue that are Site was designed with interior drive aisles that loop the sites that are compatible with two-way traffic and allow for large vehicles such as trash truck to service the site. The placement of the dental office building is towards the western half of the property so that its tower element engages the Mount Vernon Avenue and City Center Court Street frontages. The Barton Road Specific Plan (BRSP) stipulates that no front, site, or rear setback is required in Planning Area 2 -Village Commercial. The Applicant has designed from the adjacent two- EXHIBIT A Attachment 1 include an enlarged scaled site plan for a clear presentation of the proposed site. Water Quality: The Applicant has addressed the stormwater runoff from the site via a Preliminary Water Quality Management Plan (PWQMP) that is provided as Attachment 4 to this agenda staff report. As designed, stormwater will be collected via a system of drains and landscape swales into an Aqua-Swirl concentrator unit before flowing into the Storm tank underground detention system. A Final WQMP is conditioned to be reviewed and approved through the Public Works Department. Parking and Circulation: The Municipal Code parking requirement for medical, dental, Packet Pg. 11 B.1 and veterinary offices/clinics is one parking space for every 200 square feet of gross floor area. Therefore, 12,406 square feet divided by 200 square feet would result in a parking requirement of 62 spaces. The Applicant has designed the site plan with eighty (80) parking spaces. In addition to the 80 spaces there are two spaces dedicated for deliveries to the dental office. By design, the project has a surplus of parking of 18 parking spaces beyond the code minimum. Building Elevations: The Project complies with the maximum building height of 35 feet which is the height to the top of the flat roofed tower element. The tower element itself is covered in a stone veneer with large window arrays on the south and west elevations. Surrounding the windows arrays on the tower is a smooth plaster finish which outlines the windows and at the top of the windows is the sign band area for future placement of business identification signage with benefit of planning and building permits. The top of the tower element is timed by a metal fascia and a metal awning accents the entrance along the south elevation of the building tower. The main building itself is 28 feet in height to the top of the roof ridge which is roofed with concrete roof tiles. The roof eaves are trimmed like the tower element with a metal fascia. Running along the base of the building is a stone veneer trim of the same material that encapsulates the tower element. The main walls of the building are covered in a smooth plaster finish. There is equipment well on the roof of the building that is recessed for all the roof mounted mechanical equipment so that none of it will be visible from the ground below. The Applicant designed the dental office building to be well articulated, with a stepping back deck facing City Center Court, the tower element at the corner, and windows have pop-out trim surrounding EXHIBIT A Attachment 1 include fully scaled and detailed elevations and full color elevation rendering for a clear presentation of the new building. Landscaping: Water efficiency is the core driver behind the design and plant selection for the landscape plan. Low and moderate water use plantings (drip line) coupled with trees (bubblers) make of the entirety of the plan. A full color detail of all the proposed ground cover, shrubs and trees are included in the plans EXHIBIT Ato Attachment 1 for reference. The landscaping is enhanced with density of plantings throughout the site with a focus on the perimeter planters, most specifically along the public rights-of-way at Mount Vernon Avenue and City Center Court. Additionally, plantings were maximized within the parking lot landscape islands. With the efforts of the Applicant to provide more than the required code minimum parking, areas that would have been additional landscape became parking spaces. Because of this the site falls a few percentage points shy of achieving the goal of 25% landscape coverage per the Barton Road Specific Plan (BRSP). To that end the Barton Road Specific Plan (BRSP) gives the Grand Terrace Planning Commission the regulations of developments within Specific Plan the based upon the merits of a Packet Pg. 12 B.1 1) A reduction in required parking spaces not to exceed 20% of the required standard. 2) Increased building height. 3) Oher development standards as approved by the Planning Commission (e.g., landscape coverage percentage%). The Applicant has requested an incentive bonus for relaxed landscape coverage percentage not to exceed 20% of the required standard of 25% landscape coverage for landscaping. The relaxation is necessary to provide parking space above and beyond the Municipal Code minimum requirement. The Applicant has indicated that they currently have 40 spaces at the Barton Road office and given this location is twice the size it would stand to reason to double the parking. Doubling the parking space count would be a measure taken to ensure that no patrons or staff overflow onto adjacent public rights-of- the landscape coverage is consistent with the Barton Road Specific Plan (BRSP) as the Project is doing lot consolidation of 3 into 1 and in doing so would result in a reduction in access points in contrast to if each lot was developed individually, and the landscaping on the project includes a semi-public pedestrian open space towards the Mount Vernon Avenue frontage with a public art piece. Staff supports this request as the increased parking above code minimum will prevent any future parking issues and the landscape plan was designed with all necessary trees and shrubs meeting the Barton Road Specific Plan bonus incentive of 20 percent landscaping coverage on site if granted. Signage: The Applicant has drawn their designs for the Projects proposed building and monument signage which has been provided as Attachment 2 to this agenda staff report. It was preliminarily reviewed by City Staff to ensure it is following signage standards in the Municipal Code and the Barton Road Specific Plan (BRSP). The tower element has sign bands that face west and south where the wall signage can be placed on the building. The site will also feature a monument sign at the southwest corner of the property for visibility along both Mount Vernon Avenue and City Center Court. The Project was conditioned to require that prior to installation of any signs, the Applicant shall submit an application with fee payment, and receive approval, for a sign permit from the Planning Division (pursuant to Chapter 18.80 of the Grand Terrace Municipal Code) and a building permit for construction of the signs from the Building Division. Lighting: The Applicant evaluated their Project site for lighting and based upon photometric analysis sited numerous light standards throughout the parling lot and landscaping areas. This will ensure that the site is safe in dark hours and that the lighting does not bleed onto adjacent sites at high levels. The City Engineer has required that the Applicant include in their project two new streetlights. One will be located on Mount Vernon Avenue, and one will be located on City Center Court. The EXHIBIT AAttachment 1 shows the placement of all onsite lighting in the parking lot area and the two streetlights in the public rights-of-way. Public Art: The Applicant has been provided the art requirements for the City and is Packet Pg. 13 B.1 aware of the necessity for art with their Project. The Applicant has included on the site plan an art area and asked that the final art piece approval be deferred to a future Planning Commission Meeting. The Applicant is required to provide to the Planning Commission for review and art piece that addresses the following: 1) The conceptual compatibility of the design with the immediate environment of the site; and, 2) Appropriateness of the design to the function of the site; and, 3) Compatibility of the design and location within a unified design character or historical character of the site; and, 4) Creation of an internal sense of order and a desirable environment for the general community by the design and location of the work of Art; and, 5) Preservation and integration of natural feature with the project; and, 6) Consideration given to the structural and surface integrity, permanence, and protection against theft, vandalism, weathering, excessive maintenance, and repair cost; and, 7) Representation of a broad variety of tastes within the community and the provision of a balanced inventory of Art in Public Places to ensure a variety of style, design and media throughout the community that will be representative of the eclectic tastes of the community; and, 8) Works of Arts or Art places should be appropriate in scale, form, and content for the immediate, general, social, and physical environments with which they relate. The cost of art for the Project shall be equal to at least 1% of the estimated total building valuation. If the cost of the proposed art is less than 1% of the estimated total building valuation then the Applicant will have to also pay into the Public Art Fund an amount equal to the difference between the Art in Public Places Program allocation and the value, including costs of acquisition and installation, of the work of art placed. EXHIBIT B Attachment 1 requires that the Applicant shall comply with the requirements of Grand Terrace Municipal Code Chapter 18.81 - Art in Public Places and submit a complete Art in Public Places Program proposal to the City. The Art in Public Places proposal for the Project will be brought before the City Planning Commission for consideration and approval prior to issuance of building permits for the dental office building. After Planning Commission Approval, the Art in Public Places art piece must be completed, installed, and inspected prior to issuance of the final Certificate of Occupancy of the building.

Finding: The plan for landscaping and open spaces provides a functional and visually pleasing setting for the structures on this site and is harmonious with the natural landscape of the area and nearby developments. Facts in Support of Finding: functional and incorporates a public plaza with benches and artwork along Mount Vernon Avenue. The public art piece will be brought back to the Planning Commission/Site and Architectural Review Board for approval prior to final occupancy of the building. The Applicant had a comprehensive landscape plan prepared for the development by Mission Landscape Architecture that utilized the landscape guidelines found within the Barton Road Specific Plan. The colorful landscaping is visually pleasing with three (3) foot high shrub screen and trees to soften the project by obscuring the parking lot from Mount Vernon Avenue and City Center Court. Overall, the landscape plan created by Mission Landscape Architecture established a unified planting with a plant schedule that includes evergreen trees and is harmonious with the natural landscape of the area and nearby developments. The surrounding developments have trees and shrubs and groundcover that will be continued on the Project site so there is no longer a gap of fallow dirt land but a modern dental office building with water efficient landscaping. The Applicant has requested an incentive bonus for reduced landscape coverage percentage not to exceed 20% of the required standard for landscaping to provide double the amount of parking on site from the Municipal Code minimum requirement to ensure that no patrons or staff overflow onto adjacent public rights-of- consistent with the BRSP as the Project is proposes to consolidate 3 lots into 1 and in doing so would result in a reduction in access points in contrast to if each lot was developed individually. The percentage to double the amount of parking on site is offset by quality and quantity of landscaping and is identified on the landscape plans. 5. Finding: There is no indiscriminate clearing of property, destruction of trees or natural vegetation or the excessive and unsightly grading of hillsides, thus the natural beauty of the city, its setting and natural landforms are preserved.

Description of Project: The proposed redevelopment project is considered a Priority Project per the San Bernardino Project Categories List. The Project area is in the City of Grand Terrace. As shown on the WQMP site plan in Section 6, the project site is approximately 1.653 acres. Refer to Section 6.1 for the WQMP site plan. The site plan shows the location of existing new office building, paved surfaces, landscaping, and proposed LID and treatment control BMPs. The existing site is an undeveloped lot with seasonal vegetation across the site. The studied area for existing condition is 1.65 acres and consists of one drainage area where runoff surface flows southwesterly to the existing curb and gutter in the public right-of-way toward an existing drain inlet. The existing project site consists of 0% impervious and 100% pervious areas. Proposed site improvements include a new office building, impervious paving areas, storm drain system, and underground infiltration area. A hydrodynamic separator (AquaSwirl unit by AquaShield) will be provided for stormwater pre-treatment prior to discharging to the new underground infiltration system (StormTank Modules) for onsite retention. Outdoor activities for the project are expected to include driving vehicles, parking, walking, trash pickup, maintenance and activities otherwise related to the conduct of an office building.

Methods applied in the following forms include: For LID BMP Design Capture Volume (DCV), the San Bernardino County Stormwater Program requires use of the P method (MS4 Permit Section XI.D.6a.ii) Form 4.2-1 6 For HCOC pre- and post-development hydrologic calculation, the San Bernardino County Stormwater Program requires the use of the Rational Method (San Bernardino County Hydrology Manual Section D). Forms 4.2-2 through Form 4.2-5 calculate hydrologic variables including runoff volume, time of concentration, and peak runoff from the project site pre- and post-development using the Hydrology Manual 2 Rational Method approach. For projects greater than 640 acres (1.0 mi), the Rational Method and these forms should not be used. For such projects, the Unit Hydrograph Method (San Bernardino County Hydrology Manual Section E) shall be applied for hydrologic calculations for HCOC performance criteria. \[NOT APPLICABLE\] Refer to Section 4 in the TGD for WQMP for detailed guidance and instructions.

For the LID DCV, the forms are ordered according to hierarchy of BMP selection as required by the MS4 Permit (see Section 5.3.1 in the TGD for WQMP). The forms compute the following for on-site LID BMP: Site Design and Hydrologic Source Controls (Form 4.3-2) Retention and Infiltration (Form 4.3-3) Harvested and Use (Form 4.3-4) or Biotreatment (Form 4.3-5). At the end of each form, additional fields facilitate the determination of the extent of mitigation provided by the specific BMP category, allowing for use of the next category of BMP in the hierarchy, if necessary. The first step in the analysis, using Section 5.3.2.1 of the TGD for WQMP, is to complete Forms 4.3-1 and 4.3-3) to determine if retention and infiltration BMPs are infeasible for the project. For each feasibility criterion in Form 4.3-1, if the answer is used to make the determination of infeasibility. Next, complete Forms 4.3-2 and 4.3-4 to determine the feasibility of applicable HSC and harvest and use BMPs, and, if their implementation is feasible, the extent of mitigation of the DCV. If no site constraints exist that would limit the type of BMP to be implemented in a DA, evaluate the use of combinations of LID BMPs, including all applicable HSC BMPs to maximize on-site retention of the DCV. If no combination of BMP can mitigate the entire DCV, implement the single BMP type, or combination of BMP types, that maximizes on-site retention of the DCV within the minimum effective area. If the combination of LID HSC, retention and infiltration, and harvest and use BMPs are unable to mitigate the entire DCV, then biotreatment BMPs may be implemented by the project proponent. If biotreatment BMPs are used, then they must be sized to provide sufficient capacity for effective treatment of the remainder of the volume- based performance criteria that cannot be achieved with LID BMPs (TGD for WQMP Section 5.4.4.2). Under no circumstances shall any portion of the DCV be released from the site without effective mitigation and/or treatment.

Volume retention estimates are sensitive to the percolation rate used, which determines the amount of runoff that can be infiltrated within the specified drawdown time. The infiltration safety factor reduces field measured percolation to account for potential inaccuracy associated with field measurements, declining BMP performance over time, and compaction during construction. Appendix D of the TGD for WQMP provides guidance on estimating an appropriate safety factor to use in Form 4.3-3. If site constraints limit the use of BMPs to a single type and implementation of retention and infiltration BMPs mitigate no more than 40% of the DCV, then they are considered infeasible and the Project Proponent may evaluate the effectiveness of BMPs lower in the LID hierarchy of use (Section 5.5.1 of the TGD for WQMP) If implementation of infiltrations BMPs is feasible as determined using Form 4.3-1, then LID infiltration BMPs shall be implemented to the MEP (section 4.1 of the TGD for WQMP).

Use Form 4.3-4 to compute on-site retention of runoff from proposed harvest and use BMPs. Volume retention estimates for harvest and use BMPs are sensitive to the on-site demand for captured stormwater. Since irrigation water demand is low in the wet season, when most rainfall events occur in San Bernardino County, the volume of water that can be used within a specified drawdown period is relatively low. The bottom portion of Form 4.3-4 facilitates the necessary computations to show infeasibility if a minimum incremental benefit of 40 percent of the LID DCV would not be achievable with MEP implementation of on-site harvest and use of stormwater (Section 5.5.4 of the TGD for WQMP).

A project proponent must develop an alternative compliance plan to address the remainder of the LID DCV. Depending on project type some projects may qualify for water quality credits that can be applied to reduce the DCV that must be treated prior to development of an alternative compliance plan (see Form 2.4-1, Water Quality Credits). Form 4.3-9 Item 8 includes instructions on how to apply water quality credits when computing the DCV that must be met through alternative compliance. Alternative compliance plans may include one or more of the following elements: On-site structural treatment control BMP - All treatment control BMP should be located as close to possible to the pollutant sources and should not be located within receiving waters; Off-site structural treatment control BMP - Pollutant removal should occur prior to discharge of runoff to receiving waters; Urban runoff fund or In-lieu program, if available Depending upon the proposed alternative compliance plan, approval by the executive officer may or may not be required (see Section 6 of the TGD for WQMP).

Vernon Avenue Grand Terrace, CA Reference: Geotechnical Engineering Investigation, Proposed Dental and Medical Buildings, NEC of Mount Vernon Avenue & City Center Court, Grand Terrace, California, Project No. 112-17056, dated August 16, 2017. Dear Mr. Kurfurst: In accordance with your request, we are providing this letter to update our previous Geotechnical Engineering Investigation report, KA Project No. 112-17056, dated August 16, 2017 for the above- referenced project site. Based on our review of the proposed site plan provided by the project representatives and our discussions with the project owners, we understand that the proposed site plan and development are similar to those described in the referenced Geotechnical Engineering Investigation report. It is our understanding that the proposed development will include the construction of a new dental office structure at the subject site. The structure is anticipated to be a two-story building with an approximate building footprint of 10,000 square feet. In addition, the proposed development is understood to include paved parking and drive areas, and localized landscaped areas. The proposed building is anticipated to be a wood-framed structure supported on a conventional shallow foundation system and incorporating slab-on-grade floor construction. Based on our recent observation of the subject site, review of the previous geotechnical investigation reports, and review of the proposed development site plan, the site and proposed development is consistent with the conclusions and recommendations of the previous Geotechnical Engineering Investigation report. Additional information to conform to seismic design requirements of the 2022 California Building Code (2022 CBC) is provided below. Attachment: Attachment 4 - PWQMP (Spring Hills Family Dentistry Site and Architectural Review 23-23) In the event these structural or grading details are inconsistent with the final design criteria, we should be notified so that we can evaluate the potential impacts of the changes on the recommendations presented in this report and provide an updated report as necessary.

California Environmental Quality Act (CEQA) Exempt Pursuant to Section §15061(B)(3) Common Sense Exemption. PRESENTED BY:Scott Hutter, Planning & Development Services Director RECOMMENDATION:It is recommended that the Planning Commission/Site and Architectural Review Board take the following actions: 1)Open the Public Hearing 2)Receive Staff Report 3)Commission Member Comment and Questions 4)Receive Public Input 5)Close the Public Hearing 6)Adopt a Resolution Of The Planning Commission/Site And Architectural Review Board Of The City Of Grand Terrace Recommending That The City Council Adopt An Amendment To Title 18 (Zoning) Of The Grand Terrace Municipal Code Amending Chapter 18.60 (Off-Street Parking) To Update Parking Requirements (Zone Change Amendment 23-01) And Find An Environmental Exemption Pursuant to Section 15061(b)(3) Of The California Environmental Quality Act (CEQA) Guidelines. CEQA exempt pursuant to Section §15061(b)(3) -Common Sense Exemption. 2030 VISION STATEMENT: This project supports Goal 3 to promote economic development by preparing for future development by updating the zoning and development codes to ensure parking standards are current per the Circulation Element Implementation Plan Goal 3.3 and Policy 3.3.2. Packet Pg. 241 C.2 SUMMARY: The City of Grand Terrace proposes a Zone Change Amendment (ZCA) 23-01 to amend parking regulations found within Chapter 18.60 (Off- clarify areas of the off-street parking requirements that are unclear such as can a car overhang into a planter area and what is the parking needed for a drive-through only restaurant with no indoor dining or take-out. BACKGROUND: Title 18 of the Municipal Code contains Section 18.60.030 which identifies off-street parking regulations for residential and non-residential uses. Through the project proposal review process, uses are reviewed for compliance with off-street parking regulations. Although Section 18.60.030 currently includes off-street parking regulations for a variety of use types, updates and modifications were needed to provide additional regulations to be more in line with development best practices. ANALYSIS: Upon receiving a recommendation from the Planning Commission/ Site Architectural Review Board regarding the proposed Zone Change Amendment, the City Council shall act as follows: A. If the Planning Commission's recommendation is for approval, the City Council shall hold a Public Hearing on the proposed Zone Change Amendment. Said Public Hearing shall be duly noticed. After conducting a Public Hearing, the City Council may approve, modify, or disapprove the recommendation of the Planning Commission, provided that any modification of the proposed amendment by the City Council not previously considered by the Planning Commission during its hearing, shall first be referred back to the Planning Commission for its consideration and recommendation. Such consideration resulting from a City Council referral shall require a Public Hearing. Failure by the Planning Commission to report to the City Council on the proposed modification within 40 days, or such longer period as the City Council may designate, shall be deemed an approval of the proposed modification by the Planning Commission. B. If the Planning Commission's recommendation is for denial, the City Council shall not be required to take any further action, unless the applicant, any member of the City Council or any other person affected by the decision, within ten (10) calendar days after the action of the Planning Commission, files an application for appeal, accompanied by the appropriate fee, with the City Clerk. Notable modifications proposed in ZCA 23-01 to parking regulations that the Planning Packet Pg. 242 C.2 Commission/Site Architectural Review Board would be recommending to the City Council are: 1. Updating parking standards for fast food restaurants with and without drive- throughs. 2. Updating gas station parking to address convenience stores and fuel pumps. 3. Added drive-through queueing standards from the Institute of Transportation Engineers. 4. Added handicapped, queued, and electric vehicle spaces into parking space counts. 5. Added a parking space overhang into a planter area into space dimensions. 6. Added a parking management plan requirement to ministerial parking adjustments. 7. Updated shared parking to require site-specific parking study from an engineer. A full accounting of the proposed modifications to Chapter 18.60 - Off-Street Parking is provided in EXHIBIT A of Attachment 1 (Planning Commission Resolution). ENVIRONMENTAL REVIEW: Zone Change Amendment (ZCA) 23-01 is exempt from California Environmental Quality Act (CEQA) pursuant to Section 15061(b)(3) - Common Sense Exemption. The Zone Change Amendment activity is covered by the common sense exemption that CEQA applies only to projects which have the potential for causing a significant effect on the environment. Where it can be seen with certainty that there is no possibility that the Zone Change Amendment activity in question may have a significant effect on the environment, the Zone Change Amendment activity is not subject to CEQA. The project will not have a significant effect on the environment because the amendment only changes administration procedures to the requirement of the municipal code. NOTIFICATION: The Public Hearing Notice for the Project was published in compliance with the City's Grand Terrace City News, posted in three public places, including Grand Terrace News Paper, City Hall Lobby and Kiosk. To date, staff has not received any comments. FINDINGS: Municipal Code Section §18.90.040 - Planning Commission Public Hearing and Recommendation, the Planning Commission/Site and Architectural Review Board shall hold a Public Hearing on any proposed amendment and shall notice said Public Hearing in accordance with Sections 65090 and 65091 of the California Government Code and with Section 18.03.070 (Public Hearing Notice) of Chapter 18.03 (General provisions). Packet Pg. 243 C.2 The Planning Commission/Site Architectural Review Board, after examination of the proposed Zone Change Amendment (ZCA) 23-01, shall make its recommendation to the City Council via a resolution. The Planning Commission/Site Architectural Review Board shall recommend approval only if it makes all necessary findings which are EXHIBIT BAttachment 1 to this agenda report. CONCLUSION: This Parking Ordinance is consistent with the spirit and intent of the Implementation Plan Goal 3.3 and Policy 3.3.2 in that is the City conducting a periodical review of the Zoning Code parking standards to assure that adequate off-street parking is available for specific land uses. The modifications to Chapter 18.60 (Off-Street Parking) are intended to address identified shortcomings of the code and make it more clear what parking is required for land uses and developments. Staff recommends that the Planning Commission/Site and Architectural Review Board approve the Resolution provided as Attachment 1 to this agenda report recommending that City Council determine that Zone Change Amendment (ZCA) 23-01 is exempt from CEQA pursuant to Section 15061(b)(3) - Common Sense Exemption and recommend City Council approve Zone Change Amendment (ZCA) 23-01.
