SUBJECT: Small Business Saturday Proclamation.
STRATEGIC GOAL: Open, Engaged and Responsive Government RECOMMENDATION:
Adopt the Proclamation declaring November 29, 2025 as Small Business Saturday.

BACKGROUND:
Saturday, November 29, 2025 is Small Business Saturday, a day to celebrate and support small businesses and all they do for their communities. California has 4.2 million small businesses, which is more than any other state in the country. Every time you pick up a coffee at your local café, grab lunch at the mom -and-pop shop or buy a new handbag from a local store, you are making an impact in your community.
ANALYSIS:
The City of Diamond Bar proudly supports Small Business Saturday and encourages residents to shop local not just during this recognized day, but all year long through its Keep It Local, Shop Diamond Bar First initiative. This ongoing economic development program highlights the vital role small businesses play in strengthening the local economy, creating jobs, and fostering community connections. By choosing to shop, dine, and do business locally, residents help ensure Diamond Bar continues to thrive as a vibrant and prosperous community.

FROM: Daniel Fox, City Manager
SUBJECT: Appropriation of PEG Funds for the Purchase and Installation of a Dedicated Air Conditioning Unit for the City Hall Broadcast Room.
STRATEGIC GOAL: Open, Engaged and Responsive Government RECOMMENDATION:
Approve a one-time appropriation in the amount of $40,000 from the restricted Public, Educational, and Governmental (PEG) Fund (Fund 270) for the purchase and installation of a dedicated air conditioning unit for the City Hall Broadcast Room.
FINANCIAL IMPACT:
Sufficient funds are available in the restricted PEG Fund to cover the cost of this purchase and installation. PEG funds are fees collected from cable television operators, and may only be used for expenditures related to the City's operation of its government access channel.
BACKGROUND:
The City Hall Broadcast Room houses a variety of recording, streaming, and broadcasting equipment that operates continuously to keep the City’s government access channel, Diamond Bar TV (DBTV), on the air 24 hours a day via Spectrum Cable Channel 3 and Frontier FiOS Channel 47. Although City Hall is served by a central HVAC system, the Broadcast Room requires a dedicated air conditioning unit to maintain proper temperature during times when the central system is not in operation.
ANALYSIS:
Staff received quotes for the installation of the new system totaling an estimated $34,600, with an additional project contingency of $5,400, for a total project cost of $40,000. A contract for this work will be issued administratively in accordance with Chapter 3.25 (Public Projects) of the City’s Purchasing Ordinance.

CITY COUNCIL AGENDA REPORT
TO: Honorable Mayor and Members of the City Council
FROM: Daniel Fox, City Manager
SUBJECT: Adoption of the 2025 California Building Standards Codes (Title 24 C.C.R.
PARTS 2, 2.5, 3, 4, 5, 7, 9, AND 11) with Local Amendments.
STRATEGIC GOAL: Safe, Sustainable and Healthy Community RECOMMENDATION:
A. Open the public hearing to receive public testimony; B. Close the public hearing; and
C. Approve for second reading by title only, waive full reading and adopt Ordinance No. 03 (2025):
"AN ORDINANCE OF THE CITY COUNCIL OF THE CITY OF DIAMOND BAR AMENDING TITLE 15 OF THE DIAMOND BAR CITY CODE AND ADOPTING, BY REFERENCE, THE 2025 CALIFORNIA BUILDING CODE, VOLUMES 1 AND 2, INCLUDING CHAPTER 1 DIVISION II, AND APPENDICES I, AND J THERETO, THE 2025 CALIFORNIA MECHANICAL CODE, AND THE APPENDICES THERETO, THE 2025 CALIFORNIA PLUMBING CODE, AND THE APPENDICES THERETO, THE 2025 CALIFORNIA ELECTRICAL CODE, AND THE APPENDICES THERETO, THE 2025 CALIFORNIA RESIDENTIAL CODE, INCLUDING APPENDICES H, J, K, AND O THERETO, THE 2025 CALIFORNIA GREEN BUILDING CODE, WITHOUT THE APPENDICES THERETO, AND THE 2025
CALIFORNIA WILDLAND-URBAN INTERFACE CODE, WITHOUT APPENDICES, TOGETHER WITH CERTAIN AMENDMENTS, ADDITIONS, DELETIONS AND EXCEPTIONS."
FINANCIAL IMPACT:
None.
BACKGROUND:
On November 5, 2025, Ordinance No. 03 (2025) was introduced to adopt the 2025 California Building Code updates. The City Council approved the first reading by a 4-0 vote, and set the matter a public hearing and second reading on November 18, 2025. There were no changes to the draft ordinance.
Ordinance No. 03 (2025) included in Attachment 1 is being presented for its second reading, public hearing and adoption.
Agenda Item #: 7.1
Meeting Date: November 18, 2025
ANALYSIS:
The proposed ordinance carries forward the City’s existing local amendments from the 2022 code cycle, with no new local modifications. Assembly Bill 306 (2025) amended Health and Safety Code §§17958 et seq., prohibiting local jurisdictions from modifying residential construction standards except where necessary for wildfire home-hardening requirements. The 2025 code cycle consolidates all wildfire home-hardening requirements into a new California Wildland-Urban Interface Code (Part 7, Title 24, CCR), developed in coordination with CAL FIRE. This consolidation does not introduce new substantive requirements but streamlines prior fire-resistance provisions previously located in multiple code parts. The local amendments proposed for adoption are continuations of existing provisions, updated only as necessary to reflect the renumbering and organizational changes in the 2025 California Codes.
NOTICE OF PUBLIC HEARING:
Pursuant to California Government Code 50022.3, a public hearing is required prior to the second reading of any ordinance amending the Building Standards Codes. Pursuant to the California Government Code 50022.3 and 6066, a public hearing notice was published in the San Gabriel Valley Tribune on November 5, 2025, and November 12, 2025.
ENVIRONMENTAL REVIEW:
The proposed ordinance does not constitute a project under the California Environmental Quality Act (CEQA), as defined by CEQA Guidelines Section 15378(b). Accordingly, the adoption is exempt from CEQA.
LEGAL REVIEW:
The City Attorney has reviewed and approved the Ordinance as to form.

Accordingly, the adoption is exempt from CEQA.
NOW, THEREFORE, the City Council of the City of Diamond Bar does hereby find, determine and ordain as follows:
Section 1: Findings in Support of Modifications to Title 24 Building Standards.
The Council does expressly find and determine that the modifications to the Title 24 building standards set forth herein are reasonably necessary to protect the health, welfare and safety of the citizens of Diamond Bar because of the following local climatic, geological or topographic conditions.
(1) The hillsides in Diamond Bar are composed of the Puente Formation, and similar weak geological materials, while neighboring flatland areas are composed of more stable fill and alluvial materials. These materials may be naturally unstable or weak in terms of physical support. These highly expansive soil conditions are vulnerable to earth movement as well as unpredictable seismic response of buildings. The unpredictable response from prior seismic events including Chino Hills, Northridge, and the Whittier earthquakes have demonstrated the need for greater quality control to ensure against poor seismic performance of multi-story structures. (2) The City experiences diverse temperatures, which promotes expansion and contraction of the soil. This condition is very damaging to expansive type soil. (3) Because of the above-described climatic and geological conditions, the City of Diamond Bar requires special engineering to support habitable structures within the unstable soil areas and requires additional measures to be taken in connection with excavation and grading activities.
(4) The City is located in a seismically active area and is in close proximity to various active faults including the Chino, Sierra Madre, Cucamonga, Whittier, San Jacinto and Raymond Faults. It is reasonably foreseeable that an earthquake would render the City particularly vulnerable to devastation.
Ordinance No. 03 (2025)
3 (5) The City has extensive hillside topography, unstable geology, watershed areas, expansive soils, and underground streams. In addition, the regional climate alternates between extended periods of drought and brief periods of rainfall. For these reasons, the City is susceptible to flood conditions. (6) Because of the above-described geological conditions within the City, and the substantial amount of freeway, railroad, and flood control facilities throughout the community, the City, in the event of an earthquake, may be unable to dispatch an adequate number of fire personnel and apparatus to suppress fires and conduct rescue operations. Moreover, the conditions within Diamond Bar likewise occur in surrounding communities, hereby rendering mutual aid assistance problematic, at best.
(7) Due to the City's topography, numerous hillside fire hazard areas are located within its boundaries.
(8) Climatic conditions within the community render it extremely likely that, in the event of seasonal high winds and earthquake occurring, the County Fire Department would be unable to suppress numerous fires occurring throughout the community. (9) Located throughout the City, as well as in the surrounding communities, are numerous concentrations of structures which have roofs constructed of thinly cut pieces of wood, otherwise known as untreated shakes, as well as untreated wood shingles. These untreated wood shakes and shingles are extremely combustible in nature.
(10) The City is located in an area climatically classified as "arid" and prone to winds of high velocity. Moreover, due to the arid nature of the area, the weather during the windy periods tends to be very warm and dry. The dry weather conditions present a significant threat of wild fire to the City's undeveloped hillsides, wild lands, and nearby homes, and highly populated areas. The potential for rapid spread of even small fires creates a need for increased levels of fire protection. (11) Sound transmission controls are necessary to protect City residents from excessive noise generated by multiple nearby freeway interchanges and large arterial streets, among other sources.
(12) Local climate makes pool ownership desirable. Children often reside in close proximity to swimming pools, making pool barriers necessary. This need is increased due to potential delays in emergency rescue response resulting from the location of hillside residences and traffic congestion. (13) The City is in an area classified climatically as “arid” and subject to seasonal high temperatures that will affect electrical wiring not designed to be retained for an extended period of time.
(14) The Council does hereby further expressly find and determine that the amendments to the Title 24 building standards, set forth herein, and as referenced below, are
Ordinance No. 03 (2025)
4 appropriate given the specific local climatic, geological or topographic conditions set forth above.
a. CBC Sections 1505.1, 1505.1.3 and 1505.1.1 – Findings 7, 8, 9, and 10. b. CBC Sections 1612.5 – Finding 5.
c. CBC Sections 1801.2, 1803.1, 1803.8, 1803.8.1, 1803.8.2, 1809.4, and Appendix J – Findings 1, 2, 3, 4, and 5.
d. CRC Sections R301.1.3.2, R309.1, R309.2, R337.1.3.1 – Findings 6, 7, 8, 9, and
10. e. CRC Section R342 – Finding 1.
f. CRC Section R341 – Finding 11.
g. CRC Section R602.10.8 – Finding 1, 2, 3, 4, and 5.
h. CBC Section 3109.4.1 and CRC R343 – Finding 12.
i. CPC Section 722.6 – Finding 3.
j. CEC Section 590.3 – Finding 13.
The following local conditions apply to the California Building Code Amendments:
(15) The City is located in a seismically active area and is in close proximity to various active faults including the Chino, Sierra Madre, Cucamonga, Whittier, San Jacinto and Raymond Faults. It is reasonably foreseeable that an earthquake would render the City particularly vulnerable to devastation.
(16) The City has extensive hillside topography, unstable geology, watershed areas, expansive soils, and underground streams. In addition, the regional climate alternates between extended periods of drought and brief periods of rainfall. For these reasons, the City is susceptible to flood conditions. (17) Because of the above-described geological conditions within the City, and the substantial amount of freeway, railroad, and flood control facilities throughout the community, the City, in the event of an earthquake, may be unable to dispatch an adequate number of fire personnel and apparatus to suppress fires and conduct rescue operations. Moreover, the conditions within Diamond Bar likewise occur in surrounding communities, hereby rendering mutual aid assistance problematic, at best.
(18) Due to the City's topography, numerous hillside fire hazard areas are located within its boundaries.
Ordinance No. 03 (2025)
5 (19) Climatic conditions within the community render it extremely likely that, in the event of seasonal high winds and earthquake occurring, the County Fire Department would be unable to suppress numerous fires occurring throughout the community. (20) Located throughout the City, as well as in the surrounding communities, are numerous concentrations of structures which have roofs constructed of thinly cut pieces of wood, otherwise known as untreated shakes, as well as untreated wood shingles. These untreated wood shakes and shingles are extremely combustible in nature.
(21) The City is located in an area climatically classified as "arid" and prone to winds of high velocity. Moreover, due to the arid nature of the area, the weather during the windy periods tends to be very warm and dry. The dry weather conditions present a significant threat of wild fire to the City's undeveloped hillsides, wildlands, and nearby homes and highly populated areas. The potential for rapid spread of even small fires create a need for increased levels of fire protection.
The Council does hereby further expressly find and determine that the amendments to the Title 24 building standards, set forth herein, are appropriate given the specific local climatic, geological or topographic conditions set forth above.

Agenda Item #: 8.1
Meeting Date: November 18, 2025
CITY COUNCIL AGENDA REPORT
TO: Honorable Mayor and Members of the City Council
FROM: Daniel Fox, City Manager
SUBJECT: City Council Discussion of Potential Amendments to Title 22 of The Diamond Bar City Code ("Development Code").
STRATEGIC GOAL: Open, Engaged and Responsive Government RECOMMENDATION:
Provide direction regarding the initiation of a Development Code amendment process related to live entertainment, parking standards, sign standards, entitlement procedures, and/or other commercial standards as may be deemed appropriate.
FINANCIAL IMPACT:
If direction to proceed is given, consultant and attorneys' fees will be incurred. Such costs are not yet known.
BACKGROUND:
At the November 4, 2025, City Council meeting, Mayor Teng expressed interest in initiating amendments to the Development Code aimed at promoting economic development and supporting the business community.
Direction is requested from the majority of the Council regarding whether to initiate the Development Code amendment process to evaluate such items as live entertainment, parking standards, sign standards, entitlement procedures, and other commercial standards.
Any amendments to the Development Code would require public hearings before both the Planning Commission and the City Council.
ANALYSIS:
If there is interest in proceeding, the amendments may be pursued either as separate ordinances addressing each topic individually, or collectively as part of a comprehensive update. Staff anticipates utilizing the Economic Development Committee and/or holding study sessions with the Planning Commission and City Council to define the scope and priorities of any proposed amendments prior to scheduling formal public hearings.
Agenda Item #: 8.1
Meeting Date: November 18, 2025
Topics of Interest
Live Entertainment
In 2010, the City Council adopted Urgency Ordinance No. 01(2010)U and Ordinance No. 02(2010), which are provided as Attachments 1 and 2 to this report. These ordinances were enacted in response to an increasing number of complaints about the secondary impacts of amusement, entertainment, and other congregation uses in commercial and office zoning districts—particularly live entertainment.
The Council may wish to consider options for permitting live entertainment under certain conditions or settings.
It is anticipated that any amendments of this nature could be prepared by staff using in-house resources.
Parking Standards
The City’s parking regulations, contained in Development Code Chapter 22.30 (Attachment 3), have not undergone a comprehensive review since incorporation. Revising these standards would be a complex and time-intensive process, especially in light of recent State laws that allow residential development on commercial property with reduced parking requirements.
If the Council expresses interest, consultant services specializing in parking demand analysis would likely be required, increasing the time and cost associated with preparing the amendments.
During the Council discussion, it would be helpful to identify any specific provisions or constituent complaints related to the City’s parking standards—such as the number of required spaces for certain uses, minimum landscape areas, or other standards perceived as overly restrictive or outdated.
Sign Standards
The City’s sign regulations (Attachment 4), like the parking standards, have not been comprehensively reviewed since incorporation. Updating these standards would also be a complex and time-intensive process.
Because recent court rulings—including those by the U.S. Supreme Court—have clarified the constitutional limits of local sign regulation, a comprehensive update would help ensure continued compliance with applicable case law.
Any such update would likely require specialized consultant assistance in commercial signage design, along with significant review by the City Attorney to ensure legal defensibility.
As with parking standards, any examples of current standards that are perceived as business-unfriendly would be useful as staff begins developing a scope of work for amending the Sign Code, if such direction is given.
Entitlement Process
The City’s land use and development permit procedures are established in Development Code Article IV.
Common entitlements for commercial uses include Zoning Clearances, Plot Plan Review, Development Review, and Conditional Use Permits.
Potential amendments to streamline or clarify these procedures could be prepared using in-house resources.
Staff will be available at the meeting to respond to specific questions about the City’s entitlement and permitting processes.

SECTION S. Purpose and findings; Urgency. Currently, the establishment of amusement, entertainment and other specified congregation uses and facilities are permitted in the commercial and office zoning districts subject to compliance with applicable development standards and approval of a conditional use permit if required. The City has received an increased number of complaints in recent years about the secondary impacts of these facilities, particularly pertaining to noise, traffic, parking and law enforcement. The City Council believes that it is necessary to enact regulations, consistent with State law, governing the operation of live entertainment in order to protect residents and businesses from the harmful secondary effects of these establishments. In order to alleviate and address this threat, this Urgency Ordinance is adopted to enact permanent regulations immediately so that there is no gap between the end of the existing interim ordinance and the effectiveness of new regulations. This Urgency Ordinance is adopted pursuant to California Government Code Section 36937 and shall take effect immediately upon adoption by a four-fifths vote of the City Council.
SECTION 9. This Urgency Ordinance is not subject to the California Environmental Quality Act (" CEQA"), as prescribed under Section 15361( b)( 3) of the CEQA Guidelines ( no potential for causing a significant effect on the environment), therefore, no further environmental review is required.

CHAPTER 22.36. - SIGN STANDARDS
Sec. 22.36.010. - Purpose.
The purpose of this chapter is to provide minimum standards to safeguard life, health, property and public welfare, and to preserve the character of the city by regulating the size, height, design, quality of materials, construction, location, lighting and maintenance of signs and sign structures not enclosed within a building, to accomplish the following:
Provide a reasonable and comprehensive system of sign controls; Encourage a desirable city character with a minimum of clutter, while recognizing the need for signs as a major form of communication;
Provide for fair and equal treatment of sign users;
Encourage signs that are well designed and pleasing in appearance by providing incentive and latitude for variety, good design relationship, spacing and location; Provide for maximum public convenience by properly directing people to various activities; and
Promote public safety by providing that official traffic regulation devices be easily visible and free from nearby visual obstructions, including blinking signs, excessive number of signs, or signs resembling official traffic signs.
(Ord. No. 02(1998), § 2, 11-3-98)
Sec. 22.36.020. - Applicability.
The sign standards provided in this chapter are intended to apply to signs in each zoning district in the city. Only signs authorized by this chapter shall be allowed in that zoning district unless otherwise expressly provided in this chapter.
If a new zoning district is created after the enactment of this chapter, the director shall have the authority to make determinations as to the applicability of appropriate sign regulations in compliance with chapter 22.04 (Interpretation of Development Code Provisions) until this chapter is amended to govern the new zoning district.
(Ord. No. 02(1998), § 2, 11-3-98)
Sec. 22.36.030. - General provisions for all signs.
Maintenance of signs. Signs and supporting hardware, including temporary signs, shall be maintained in good repair and functioning properly at all times. Repairs to signs shall be of equal or better in quality of materials and design as the original sign. Signs which are not properly 11/6/25, 4:05 PM Diamond Bar, CA Code of Ordinances

(b)
maintained and are dilapidated shall be deemed to be a public nuisance.
When existing signs are removed or replaced, all brackets, poles, and other supports that are no longer required shall be removed. Unpainted areas shall be painted to match the adjacent portion of the building or sign support structure.
Measurement of sign height. Sign height shall be measured from the uppermost part of the sign used in determining the area of the sign to the elevation of the base of the sign nearest the curb of the public street or nearest the base of the adjacent on-site building, whichever is closer to the location of the sign.

Measurement of sign area.
The surface area of a sign shall be calculated by enclosing the extreme limits of all writing, logo, representation, emblem, or other display within a single continuous perimeter composed of squares or rectangles with no more than eight lines.
Supporting framework or bracing that is clearly incidental to the display itself shall not be computed as sign area.
Signs composed of more than one sign face shall be computed as including only the maximum single display surface that is visible from any ground position at one time.
Where a sign consists of one or more three-dimensional objects (i.e., balls, cubes, clusters of objects, sculpture or statue-like trademarks), the sign area shall be measured as their maximum projection upon a vertical plane.
For signs that incorporate time and temperature devices, the area of these devices shall not be included in the total area of the sign.
Illumination of signs. The artificial illumination of signs, either from an internal or external source, shall be designed to eliminate negative impacts on surrounding rights-of-way and properties.
External light sources shall be directed and shielded to limit direct illumination of any object other than the sign.

Signs shall not have blinking, flashing, or fluttering lights or other illuminating devices that have a changing light intensity, brightness or color.
Colored lights shall not be used at a location or in a manner so as to be confused or construed as traffic control devices.
Neither the direct nor reflected light from primary light sources shall create a hazard to operators of motor vehicles.
Reflective-type bulbs and incandescent lamps that exceed 15 watts shall not be used on the exterior surface of signs so as to expose the face of the bulb or lamp to a public right-of-way or adjacent property.
Light sources shall utilize energy-efficient fixtures to the greatest extent possible.

Freestanding monument signs shall contain the street address of the use(s) in compliance with section
22.36.120(b) (Freestanding monument signs).
Substitution clause. Notwithstanding any other provision of this Code, any noncommercial copy may be substituted for any commercial copy on any sign permitted by this Code. If noncommercial copy is substituted, the resulting sign will continue to be treated as the original commercial sign under this Code and will not be deemed or treated as an off-site sign. The content of any noncommercial copy on any sign otherwise permitted by this Code may be changed without complying with any provisions of this Code normally required for sign copy or design approval.

Sec. 22.36.060. - Comprehensive sign program.
Purpose. The purpose of a comprehensive sign program is to integrate a project's signs with the design of the structures to achieve a unified architectural statement. A comprehensive sign program provides a means for the flexible application of sign regulations for multitenant projects and other users of multiple signs in order to encourage creativity and provide incentive and latitude in the provision of multiple signs and to achieve, not circumvent, the intent of this chapter.

Comprehensive sign program required. Standards for signs provided in this chapter shall serve as a reference for evaluating comprehensive sign program applications. A comprehensive sign program shall be required whenever any of the following circumstances exist:
New multitenant developments of three or more separate tenants that share either the same parcel or structure and use common access and parking facilities; Whenever five or more signs are proposed for a new or existing development; Whenever wall signs are proposed on structures over two stories in height; Whenever two or more signs are requested by a single tenant in an existing multitenant project that currently is not covered by a comprehensive sign program; and Whenever the director determines that a comprehensive sign program should be developed for a project due to special circumstances (e.g., the number or size of signs proposed, constrained visibility of the site, location of site relative to major transportation routes, etc.).
Single-use buildings. For single-use buildings with 200 feet or more of frontage, a comprehensive sign program may be approved which exceeds the maximum aggregate sign area up to a limit of 200 square feet, provided that:
No single wall sign so approved exceeds 125 square feet, and no freestanding sign exceeds 24 square feet, except as stated by the provisions of this chapter.
Any two signs placed on the same frontage which taken together exceed 125 square feet shall be separated by no less than one-half the length of the building frontage.
No comprehensive sign program shall be approved which allows any combination of signs which exceed an overall maximum of 125 square feet per use, except as stated by the provisions of this chapter.
Lessees to be informed of comprehensive sign program. Lessees within developments subject to the requirements of an approved comprehensive sign program shall be made aware of the program in their lease and their responsibility to follow the approved comprehensive sign program.
Findings. In approving a comprehensive sign program, the commission hearing officer shall make the following findings:
The comprehensive sign program satisfies the purpose of this chapter and the intent of this section;
The signs enhance the overall development, are in harmony with, and are visually related to other signs included in the comprehensive sign program and to the structure and/or uses they identify, and to surrounding development;
The comprehensive sign program accommodates future revisions which may be required due to changes in uses or tenants; and

The comprehensive sign program complies with the standards of this chapter, except that flexibility is allowed with regard to sign area, number, location, and/or height to the extent that the comprehensive sign program will enhance the overall development and will more fully accomplish the purposes of this chapter.
Revisions to comprehensive sign programs. Revisions to a comprehensive sign program may be approved by the director if it is determined that the revision is minor and that the intent of the original approval, and any conditions attached thereto, are not affected. Revisions that would substantially deviate from the original approval may require planning commission approval. (Ord. No. 02(1998), § 2, 11-3-98)
Sec. 22.36.070. - Sign design guidelines.
In determining the consistency of each proposed sign with the purposes of this chapter, the following guidelines shall be applied:
That the proposed sign will be legible to the intended audience under normal viewing conditions, based on its proposed location, and the design of its visual element; That the proposed sign will not obscure front view or detract from existing signs, based on its location, shape, color, and other similar considerations; That the proposed sign will be in harmony with adjacent properties and surroundings, based on the size, shape, height, color, placement, and the proximity of the proposed signs to adjacent properties and surroundings;
That the proposed structure, sign or display will be designed, constructed, and located so that it will not constitute a hazard to the public; and
That the proposed sign is not designed to be viewed from a freeway, unless specifically provided for under the terms of this chapter.
(Ord. No. 02(1998), § 2, 11-3-98)
Sec. 22.36.080. - Prohibited signs.
