PAGE NO. 2
themselves with subjects not covered by the Codes or are reasonable necessary to safeguard life and property within the City of Yorba Linda.
NOW, THEREFORE, BE IT RESOLVED by the City Council of the City of Yorba Linda as follows:
Section 1
I. Climatic Conditions
A. Hot Drying Winds. The jurisdiction of Yorba Linda is located in a semi-arid Mediterranean type climate. It annually experiences extended periods of high temperatures with little or no precipitation. Hot, dry (Santa Ana) winds, which may reach speeds of 70 M.P.H. or greater, are also common to the area. These climatic conditions cause extreme drying of vegetation and common building materials creating extreme fire hazard conditions. Frequent periods of drought and low humidity add to this fire danger. This predisposes the area to large destructive fires (conflagration). In addition to directly damaging or destroying buildings, these fires are also prone to disrupt utility services throughout the County. Obstacles generated by strong wind, such as fallen trees, street lights and utility poles, and the requirement to climb 55 feet vertically will greatly impact the response time to reach an incident scene. Additionally, there is a significant increase in the amount of wind force at 60 feet above the ground. Use of aerial type fire fighting apparatus above this height would place rescue personnel at increased risk of injury.
B. Strong Winds. The dry climatic conditions with strong winds contribute to the rapid spread of even small fires originating in high-density housing or vegetation. These fires spread very quickly and create a need for increased levels of fire protection.
The added protection of fire sprinkler systems and other fire protection features will supplement normal fire department response by providing immediate protection for the building occupants and by containing and controlling the fire spread to area of origin. Fire sprinkler systems will also reduce the use of water for firefighting by as much as 50 to 75 percent.
C. Heavy Precipitation. The climate alternates between extended periods of drought and brief flooding conditions. The winter months can experience heavy rainfall of up to 6 inches per hour. Flood conditions may affect the Orange County Fire Authority's ability to respond to a fire or emergency condition. Floods also disrupt utility services to buildings and facilities within the County. Hillside erosion due to water run-off from typical to torrential rain in hillside communities must be managed.
Therefore, area drains in mandated pool decks and their surrounding landscaped areas divert such run-off to the City's storm drain systems, thus reducing hillside erosion.
D. Water Availability. Water demand in this densely populated area far exceeds the quantity supplied by natural precipitation; and although the population continues to grow, the already-taxed water supply does not. California is projected to increase in population by nearly 10 million over the next quarter of a century with 50 percent
RESOLUTION NO. 2025-5952
PAGE NO. 3
of that growth centered in Southern California. Due to storage capacities, consumption, and a limited amount of rainfall, future water allocation is not fully dependable. This necessitates the need for additional and on-site fire protection features. It would also leave tall buildings vulnerable to uncontrolled fires due to a lack of available water and an inability to pump sufficient quantities of available water to floors in a fire.
E. Semi-arid Mediterranean Climate. The warm, dry climate of Yorba Linda is conducive to private swimming pool ownership. Increased numbers of adjacent private swimming pools also increases the likelihood of children drowning where pool enclosures are not of a permanent design. Therefore, leaving a pool unprotected by the use of temporary, electromechanical, or other means of protection that can be turned off, removed or left open for untold periods of time creates an extremely dangerous situation within communities and containing large numbers of private swimming pools.
Il. Topographical Conditions
A. Hillside Community. Natural slopes of 15 percent or greater generally occur throughout the foothills of Orange County. Yorba Linda has a sizeable hillside community with little to no remaining developable lowlands. Mass grading for development on hillsides has become easier and cost effective. Therefore, mass grading on hillsides has increased the amount of structures constructed on and around sloping terrain. Sloped terrain places physical burdens upon fire fighters and their equipment in responding to emergencies and attacking fires.
Hillside development mandates construction to comply with setbacks from slopes and typically requires soil reports and fuel modification plans to be prepared.
B. Traffic and Circulation Congestion is an artificially created, obstructive topographical condition, which is common throughout Orange County.
C. Response Time. These topographical conditions combine to create a situation, which places fire department response time to fire occurrences at risk, and makes it necessary to provide automatic on-site fire-extinguishing systems and other protection measures to protect occupants and property.
Ill. Geological Conditions.
The Orange County region is a densely populated area that has buildings constructed over and near a vast and complex network of faults that are believed to be capable of producing future earthquakes similar or greater in size than the 1994 Northridge and the 1971 Sylmar earthquakes. Earthquake faults run along the northeast and southwest boundaries of Orange County. The Newport-Inglewood Fault located within Orange County was the source of the destructive 1933 Long Beach earthquake (6.3 magnitude) which took 120 lives and damaged buildings in an area from Laguna Beach to Marina Del Rey to Whittier. In December 1989, another earthquake occurred in the
RESOLUTION NO. 2025-5952
PAGE NO. 4
jurisdiction of Irvine at an unknown fault line. Regional planning for reoccurrence of earthquakes is recommended by the State of California, Department of Conservation.
A. Earthquake Faults. Previous earthquakes have been accompanied by disruption of traffic flow and fires. A severe seismic event has the potential to negatively impact any rescue or fire suppression activities because it is likely to create obstacles similar to those indicated under the high wind section above.
With the probability of strong aftershocks there exists a need to provide increased protection for anyone on upper floors of buildings. The October 17, 1989 Santa Cruz earthquake resulted in one major fire in the Marina District (San Francisco). When combined with the 34 other local fires and over 500 responses, the department was taxed to its fullest capabilities. The Marina fire was difficult to contain because mains supplying water to the district burst during the earthquake. This situation creates the need for both additional fire protection and automatic on-site fire protection for building occupants. State Department of Conservation noted in their 1988 report (Planning Scenario on a Major Earthquake on a Newport-Inglewood Fault Zone, page 59), "unfortunately, barely meeting the minimum earthquake standards of building codes places a building on the verge of being legally unsafe."
B. Landslides and Roadway Flooding. Road circulation features located throughout the County also make amendments reasonably necessary. Located throughout the County are major roadways, highways and flood control channels that create barriers and slow response times. Hills, slopes, and street and storm drain design accompanied with occasional heavy rainfall, causes roadway flooding and landslides and at times may make an emergency access route impassable. There are areas in Orange County that naturally have extended emergency response times that exceed the 5-minute goal.
C. Corrosive Soils. Soils throughout the County possess corrosive properties that reduce the expected usable life of water services when metallic pipes and concrete in contact with soils.
D. Oil Fields. Portions of the County contain active or former oil production fields.
These areas contain a variety of naturally occurring gases, liquids and vapors.
These compounds present toxicity or flammability hazards to building occupants. Evaluation of these hazards and the risks they pose to development is necessary to implement appropriate mitigation.
E. Chino Hills State Park. The entire northern and eastern boundaries of Yorba Linda are adjacent to the Chino Hills State Park. The park area stretches nearly 31 miles, from the Santa Ana Mountains to the Whittier Hills. There are several different scrub and chaparral communities including coastal sage scrub, California sagebrush, California buckwheat and purple sage, as well as a mixed chaparral community that becomes fuel for fires during summer months. The winds mentioned in Paragraph lA above, can allow pieces of burning wood roofing material or debris behind solar panels mounted to roofs, to become
RESOLUTION NO. 2025-5952
PAGE NO. 5
flying brands that can be carried to other locations and thereby spread fire quickly. Therefore, a City wide ban of untreated wood roofing material should continue, with a minimum requirement for Class A roofing. Mandating clearance requirements for solar panels attached to roofs will reduce the accumulation of debris behind the panels, thus eliminating fire potential and preserving the water protective integrity of a roof covering by not impairing drainage.
F. Soil Structure. The structure of soil can either block or allow effluent waste, generated by private sewage disposal systems, to percolate into underground water supplies. The City is dependent on local water wells that are fed by underground water aquifers and the Santa Ana River. Due to health concerns related to the use of private systems in close proximity to heavily populated residential areas, the City must regulate the use of certain private sewage disposal systems. Soils routinely experienced by developers and other builders in Yorba Linda are expansive and routinely requires structures to be designed accordingly. Therefore, a blanket mandate is necessary for new construction to meet expansive soil construction requirements unless otherwise justified by a soils report.
Due to the topographical conditions of sprawling development separated by waterways and narrow and congested streets and the expected infrastructure damage inherent in seismic zone described above, it is prudent to rely on automatic fire sprinkler systems to mitigate extended fire department response time and keep fires manageable with reduced fire flow (water) requirements for a given structure. Additional fire protection is also justified to match the current resources of firefighting equipment and personnel within the Orange County fire Authority.
Section 2
The City Council hereby finds that the amendments to the Codes as set forth in detail in Ordinance Nos. 2025-1116, 2025-1117, 2025-1118, 2025-1119, 2025-1120, 2025-1121, 2025-1122, 2025-1123, 2025-1124, 2025-1125, 2025-1126 are reasonably necessary based on the climatic, geographical and topographical conditions cited in Section I of this Resolution and apply to the amendments as follows.

It is recommended that the City Council adopt Resolution No. 2025-5951 declaring the intent to set a public hearing on October 21, 2025, for the 2025 Weed Abatement Program.
BACKGROUND
Every year the City Council implements a Weed Abatement Program to minimize hazardous fire conditions within the City. This involves a multi-step notification process, requiring property owners with large areas of undeveloped property, to perform weed abatement/vegetation reduction prior to the heightened portion of the fire season. The City does obtain a high degree of voluntary compliance from property owners (more than 1,100 properties) due to extensive outreach efforts, inspections and follow-up notifications; however, there is one property owner that has failed to comply.
Article 2, Section 39560 et seq. of the California State Government Code authorizes cities to perform weed abatement on private properties that fail to comply through declaring such properties as a public nuisance. The adoption of Resolution No. 2025-5951 is required to declare the City's intention to set a Public Nuisance Hearing on October 21, 2025, related to the Weed Abatement Program and to receive any protest relating to the potential abatement of any remaining, non-compliant, private properties.
Per the provisions of Article 2, Title 4, Division 3, Part 2, Chapter 13, comprised of Sections 39560-39588, inclusive, of the Government Code of the State of California, provided that upon the second and any subsequent occurrence of such nuisance on the same parcel or parcels within the same calendar year, no further hearings need to be held, and it shall be sufficient to mail a postcard notice to the owners of the property as they and their addresses appear upon the current assessment roll, in accordance with the provisions for such notice contained in Section 39562.1 of the Government Code of the State of California. This Government Code provision allows the City, if necessary, to further abate any property declared a public nuisance currently that experiences hazardous regrowth within the
DECLARING PUBLIC NUISANCE, INTENT TO PROVIDE ABATEMENT, AND SETTING
THE DATE FOR THE PUBLIC HEARING
P a g e | 2
remainder of this year, without need for another public hearing or other administrative process (other than mailed postcard notification).
DISCUSSION
The Weed Abatement Program is a budgeted item under the Public Nuisance section of the Community Preservation budget. Over the last couple of years, due to a high degree of resident compliance, the City's cost to abate non-complying properties has averaged less than $10,000. The cost of abatement shall be assessed upon the private parcels requiring abatement, resulting in eventual reimbursement of City funds expended. Staff will return to the City Council at a future date for the public hearing to consider attachment of special assessment liens to any affected properties.
FISCAL IMPACT
Should the City need to perform weed abatement on any private properties, costs would be anticipated to not exceed $10,000. However, these costs would be recovered through the placement of special assessment liens on affected properties resulting in eventual reimbursement of City expended funds.
ALTERNATIVES
Continue to provide annual notices to properties that meet the Weed Abatement criteria, with no formal procedure or proactive follow-up, other than through standard code enforcement protocol, which is reactive in nature; however, given the serious nature of wildfires in the City, it is strongly recommended to proceed with the abatement process.

BACKGROUND
On March 15, 2023, a sinkhole occurred along the cart path to Hole 10 at the Black Gold Golf Course (see vicinity map in Attachment 1) due to heavy winter storms that year.
Through emergency investigations, it was discovered the 48-inch storm drainpipe underneath was substantially blocked, partially collapsed, and restricted storm water flow for approximately 75 feet from the pipe inlet.
Within the past two years, the City made exhaustive efforts to perform geotechnical and soil investigations, acquire CCTV footage, clear and clean the pipe debris, evaluate alternatives for restoration, and eventually procure professional design services to prepare contract documents for the permanent solution.
Kimley-Horn (selected design consultant) along with City staff decided on a permanent repair project that consists of replacing 110 linear feet of drainpipe with 48-inch reinforced concrete pipe (RCP), lining 400+ feet of existing pipe with structurally reinforced liner, constructing additional manholes for access, and restoring all golf course amenities (landscape, irrigation, etc) impacted by the work.
DISCUSSION
Approval of Plans and Specifications
On October 17, 2023, the City Council approved the award of a Professional Services Agreement to Kimley-Horn and Associates for the design of Black Gold Storm Drain Improvement Project. The contract documents, including the plans, specifications, and bid proposal from Kimley-Horn and Associates are on file with the City Clerk.
Construction Management, Materials Testing, and Inspections Services Staff typically rely on consultant services to provide construction management, materials testing, and inspection for larger Capital Improvement Projects. Proposals were requested from engineering and golf course design consultants, including those on the City’s on-call list for Construction Management and Inspection Services, and Geotechnical Services. Six (6) proposals were received and evaluated by Public Works and Parks & Recreation staff.
Based on demonstrated experience, understanding of project challenges, availability of resources, cost, and ability to facilitate public relations between the contractor and the Golf Course patrons, it was determined that H.W. Lochner, Inc. would best meet the needs of the City. H.W. Lochner (also formerly known as KOA Associates) has extensive experience providing local jurisdictions and golf course facilities with construction management, materials testing, and inspection services for capital improvement projects and private development. H.W. Lochner has also worked with the selected contractor on other projects through which they’ve been able to partner and deliver successful projects. This experience

has resulted in positive references by three different local jurisdictions. Staff is recommending the approval of a Professional Service Contract with H.W. Lochner, Inc. in the amount of $468,925.00 (Attachment 2) to provide Construction Management, Materials Testing, and Inspection Services.
Construction Bid Analysis
Plans and specifications were advertised for bids on July 10th and July 17th, 2025. Formal bidding procedures have been followed in conformance with the State Public Contract Code and the City of Yorba Linda Municipal Code. A total of three (3) bids were received and opened by the City Clerk’s office on August 7, 2025 with the following results:
Table 1 – Bid Summary
Bidder Bid Amount
Big Ben, Inc. $ 2,468,164.10
Environmental Construction, Inc. $ 2,495,456.48
Clarke Contracting Corporation $ 3,160,500.00
City staff reviewed all bids and determined that available funding from the CIP Project Account (MS231002) is sufficient to award the contract to the lowest bidder. The source of funds will be entirely from the City’s Master Plan of Drainage Fund. While the overall drainage fund is sufficient to cover the project, there will need to be an Intrafund Loan Agreement to supplement the funds specific to Watershed 1 where Black Gold Storm Drain resides. The details of this transfer of funds from an adjacent watershed are described below in the Fiscal Impact Section.
The apparent lowest bidder was Big Ben, Inc. However, the City received a bid protest letter (see Attachment 6) on August 11, 2025 from the third bidder (Clarke Contracting Corporation) against the license validity of the landscape restoration subcontractor (West Coast Golf Construction, Inc.) being proposed by both Big Ben, Inc. and Environmental Construction, Inc. teams. The protest letter challenged the contractor license affiliation for West Coast Golf Construction, Inc. However, the City reviewed the letter, investigated the claim, and determined the protest does not have merit.
Big Ben, Inc. has successfully delivered similar projects with other municipalities within Orange County including Yorba Linda Water District and City of Anaheim. References were verified for both Big Ben, Inc. and West Coast Golf Construction, Inc. and positive comments were received regarding their quality of work and ability to complete projects successfully.
Based on this evaluation, staff recommend awarding the construction contract to Big Ben, Inc. in the amount of $2,468,164.10.

FISCAL IMPACT
The estimated construction-related project expenditures, including standard 15% contingencies, are shown below:
Table 3 – Estimated Project Expenditures (for Construction Phase) Construction Management, Materials Testing, Inspection Services H.W. Lochner Inc. $ 468,925.00
15% Contingency $ 70,338.75

15% Contingency $ 370,224.62
Subtotal: $ 2,838,388.72
TOTAL CONSTRUCTION PHASE: $ 3,377,652.47
The construction of Black Gold Emergency Storm Drain Repair Project (MS231002) is being entirely funded by local Master Plan of Drainage Fund (403) as programmed in the TwoYear CIP Fiscal Year 2025-2026 budget of $4,475,000. Prior efforts to obtain reimbursements through Federal Emergency Management Agency (FEMA) Public Assistance Recovery funds were unsuccessful.
Fund 403 consists of 10 drainage watersheds in which Black Gold Golf Course resides in Watershed 1. Total construction appropriations for the project ($3,377,652.47 as noted above) will deplete the allocation for Watershed 1, with a current remaining cash balance of

$1,855,088.00 as of this report. The shortfall in the amount of $1,522,564.47 will be borrowed from Watershed 2. Staff recommend approval of the intrafund loan agreement based upon a term of 30 years with an interest rate of 1.25%, which is the average of the LAIF rate of the past 15 years. Future loan repayments will be added to budgets in accordance with payment terms in the attached amortization schedule, with no pre-payment penalties. Staff anticipate near term revenue coming into Watershed 1 from loan repayments from the Black Gold loan in the amount of $240,000 annually for the next few years, along with potential incoming revenue from select housing element sites being redeveloped within that watershed for an estimated amount of $1.049 million. If the ability to repay is being called into question or substantial revenue is not raised by the 10-year mark, staff will reevaluate the repayment plan with the Finance Department and City Manager at such time.
ALTERNATIVES
Do not award the contracts and agreements, and do not proceed with the permanent storm drain repairs. This would increase risk to Black Gold Golf Course as it would increase potential for localized flooding and disrupt operations if the storm drain was to fail again. As an interim repair, the existing drainage system is plugged and taken off-line until this permanent repair project. During major rain events, Black Gold Golf Course relies on a pump system that requires staff to operate and be on site.
The City Council may choose not to award the proposed public works construction contract and reject all bids. However, staff do not recommend this alternative, as it would delay the implementation of permanent repairs. The bid received from Big Ben, Inc. is competitive, and there is no guarantee that re-advertising the project will yield more favorable pricing.
The City Council may choose not to approve the intrafund loan agreement within Master Plan of Drainage Fund or assign different terms and interest rate. Staff does not recommend these alternatives as it would delay the permanent project or require General Funds to make up the shortfall if the project was to proceed.
