1 To submit a written public comment:

E-mail [email protected] before the Council discusses the item, noting the agenda topic or number in the subject line. Comments received up to three hours before the meeting will be distributed to the Council and included in the record but not read aloud during the meeting..

The Mayor has the authority to rule any speaker out of order, including speakers during the Public Comment period; If the subject raised is not within the subject matter jurisdiction of the City Council, during a public hearing or a general business item if the speaker is not presenting testimony or evidence relevant to the matter or if the speaker becomes disruptive to the proceedings and conduct of the meeting.

The Mayor also has the authority to order any person who willfully interrupts the meeting to be removed. All persons are expected to always conduct themselves with civility and courtesy. All persons giving comments shall speak directly to the Council and address issues, not individuals. Personal attacks, cursing and outbursts from the audience in support or opposition to a speaker are not tolerated to foster an environment where everyone feels welcome to speak.

LEVINE ACT:

The Levine Act (California Government Code Section 84308) limits campaign contributions that may be made to elected or appointed City officials (including councilmembers and the mayor) and certain candidates for elective city offices. The Act prohibits an agent of a party from contributing any amount to councilmember while a proceeding for a contract valued at $50,000 or more, permit, license, or other entitlement for use is pending that does not solely involve purely ministerial decisions. The Act also prohibits parties and participants in the above entitlement proceedings from contributing more than $500 during the proceeding and for 12 months after the proceeding and requires disclosure of the prohibited contributions. The Act prohibits certain officials, including local elected officials, from taking part in an entitlement proceeding if the official has received a contribution exceeding $500 from a party or participant in the proceeding within the preceding 12 months. An official is also prohibited from accepting, soliciting, or directing a contribution exceeding $500 from a party or participant in the proceeding for 12 months after a final decision is rendered in such a proceeding. The law is complex, and this brief description is not legal advice. If you or an agent have made any campaign contributions to a councilmember in the 12 months before a proceeding in which you have an interest or you are contemplating making a contribution within the 12 months after such a proceeding, you are urged to review the Levine Act and consider consulting an attorney. The California Fair Political Practices Commission (FPPC) is responsible for administering the Levine Act. More information about the Act and its implementing regulations can be found on the FPPC’s website here:

ACCESSIBILITY

5 Belmont Fire
Hazard Severity
Zone Maps (LRA)
and
Ordinance Updates • Carisa Workman – Fire Marshal • 5/13/25 • San Mateo Consolidated Fire Department
6 What are Fire Hazard
Severity Zones?
• The Fire Hazard Severity Zone (FHSZ) maps are
developed using a science-based and field-tested
model that assigns a hazard score based on the
factors that influence fire likelihood and fire
behavior.
• Many factors are considered such as fire history,
existing and potential fuel (natural vegetation),
predicted flame length, blowing embers, terrain,
and typical fire weather for the area.
• There are three levels of hazard in the State
Responsibility Areas:
• Moderate
• High
• Very high
•Moderate
•High
•Very High
7 8
Why we Need to
Adopt the Maps
• New legislation, Senate Bill 63 (Stern, 2021), now
requires the adoption of all three Fire Hazard
Severity Zone classes in the Local Responsibility
Area.
• Previously only Very High Fire Hazard Severity
Zones were required for adoption in Local
Responsibility Areas.
• Government Code Sections 51178 and 51179
•Moderate
•High
•Very High
9 California LRA Map
Rollout Plan
10 Why we Needed to
Update the Ordinance?
• Previous ordinance language stated High and
Very High Fire Zones.
• Previous ordinance language did not allow for
Moderate Zones.
• New ordinance language gives us the authority to
continue to reduce risk in our Wildland/Urban
Interface (WUI) areas by including moderate
zones as identified by the new LRA maps.
•Moderate
•High
•Very High
11 SMC Fire Code Amendments
• LOCAL AGENCY FIRE HAZARD SEVERITY ZONE.
• Property within a Local Responsibility Area (LRA) served by the San Mateo Consolidated Fire Department that has been designated by the Office of the State Fire Marshal and/or the San Mateo Consolidated Fire Department as a Moderate, High, or Very High Fire Hazard Severity Zone.
• SECTION 4905.3.1 LOCAL AGENCY MODERATE FIRE HAZARD SEVERITY ZONE REQUIREMENTS. • 4905.3.1 Local Agency Moderate fire hazard severity zone requirements. Buildings constructed in local Agency Moderate Fire Hazard Severity Zones shall comply with section 4905.2.
• SECTION 4907.1 GENERAL. AMENDED
• 4907.1 General. Defensible space will be maintained around all buildings and structures in State Responsibility Areas (SRA) as required in Public Resources Code 4290 and “SRA Fire Safe Regulations” California Code of Regulations, Title 14, Division 1.5, Chapter 7, Subchapter 2, Section 1270.
• Buildings and structures within the Local Responsibility Area (LRA) shall maintain defensible space as outlined in Government code sections 51175 through 51189 in moderate, high, and very high fire hazard severity zones as designated by the Office of the State Fire Marshal and as confirmed or modified by the San Mateo Consolidated Fire Department. 12 State Response Area (SRA)
Local Response Area (LRA)
• SRA requirements N/A
• LRA requirements
• SMCFD recommends
following more restrictive
requirements for all
designated fire hazard
zones.
• Chapter 7A
• Defensible Space

Miscellaneous
Structures
14 Hazard
Is based on physical conditions that create
a likelihood and expected fire behavior
over a 30 to 50-year period without
considering mitigation measures such as
home hardening, recent wildfires, or fuel
reduction.

Risk
Is the potential damage a fire can do to
the area under existing conditions,
accounting for any modifications such as
fuel reduction projects, defensible space,
and ignition resistant building
construction
Hazard Vs. Risk
15 What is
Defensible Space? • Buffer zone between structures
and surrounding wildland areas
• Key to slowing or stopping fire
spread and protecting homes
from embers, flames, or heat
• Gives firefighters a safe area to
defend property
• This is key to keeping your family
and home safe from the
damaging effects caused by fires
16 Creating Defensible Space
SMCFD Services:

Proactive Wildland/Urban Interface
(WUI) property inspections
Work with neighboring cities to
ensure open space is managed
Investigate fire hazards concerns
What residents should do:

Create and maintain a
defensible space
Remove dead or dying
vegetation
Consider home hardening

ORDINANCE NO. ______

AN ORDINANCE OF THE CITY OF BELMONT REGULATING INDEMNITY FOR

APPLICANTS AND HOLDERS OF PERMITS, LICENSES AND OTHER CITY

ENTITLEMENTS, ENCROACHMENTS, AND RIGHT OF WAY MAINTENANCE THE CITY COUNCIL OF THE CITY OF BELMONT DOES ORDAIN AS FOLLOWS:

SECTION 1. LEGISLATIVE FINDINGS
(a) The City Council finds that the issuance of licenses, permits, and other approvals under state and local regulations creates a risk to the city as a result of issuing those licenses, permits and approvals, which are primarily for the benefit of the applicant, licensee or permittee. This is especially true for projects for which discretionary city approvals are necessary and for which, in addition to other legal requirements, environmental review is required under California Environmental Quality Act (CEQA) because, among other things, substantial City time, effort, and resources are expended in complying with CEQA’s requirements and other legal requirements necessary before granting such approvals.
(b) Judicial challenges arising from or related to the issuance of licenses, permits and other approvals, especially CEQA determinations for projects requiring discretionary approvals, are costly and time consuming. In addition, project opponents often seek an award of attorneys’ fees and costs in such challenges and the city typically may not recover its fees and costs if it is successful defending the challenge. The city’s unequal exposure to unrecoverable defense cost and the opposing party’s litigation costs invites challenges and disadvantages the city in resolving challenges even when the merits arguably favor the city. As project applicants, licensees, and permittees are the primary beneficiaries of such approvals, it is appropriate that such applicants, licensees and permittees should bear the expense of defending against any such judicial challenge, and bear the responsibility for any costs, attorneys’ fees, and damages which may be awarded to a successful challenger.

SECTION 2. BCC SECTION 1-18 ADDED
Belmont City Code Section 1 is added to read:

Sec. 1-18 Indemnification for Approvals
(a) Applications and approvals generally.
(1) Except as provided in subsection (b), and to the fullest extent allowed by law, an applicant for city approval must, as a condition of application and approval, defend, indemnify, and hold harmless the city and its officers, officials, employees and volunteers against and from any and all damage, liability, loss, claim, action or proceeding connected with or arising out of any claim, action or proceeding either to attack, set aside, void, annul, or challenge the validity of any approval or otherwise in connection with the approval, and to bear its own costs in any action or proceeding as a real party in interest. The city is not obligated to defend or to contribute to the cost of defense of any action or proceeding to attack, set aside, void, annul, or challenge the validity of any approval, or reimburse the applicant for any liability, cost or loss incurred by the applicant as a result of such action or 24

proceeding or its disposition including but not limited to any settlement, cost, or attorneys fees paid by applicant or award against the applicant.
(2) Within 14 days of receiving notice of a claim, action or proceeding to attack, set aside, void, annul, or challenge the validity of approval or in connection with the approval, an applicant must notify the city in writing that it will defend the city and its bodies, officers, employees, and agents in the action or proceeding without qualification or reservation. (3) If the applicant fails to timely provide the notice required by subsection (a)(2) or fails to timely undertake the unqualified and unreserved defense of the city and its bodies, officers, employees, and agents, the city may settle any such claim, action or proceeding on any terms it determines acceptable without incurring any liability to the applicant and without prejudicing any rights of recovery from the applicant under this section or any provision of law.
(4) For purposes of subsection (a), an “approval” means the grant of any license, permit, entitlement or other approval under this Code or any city ordinance, rule or regulation by any person, entity, or body on behalf of the city.
(5) The city will promptly notify the applicant or approval holder of any claim, action, or proceeding in connection with any approval or that is brought to attack, set aside, void or annul an approval.
(6) The city retains the right to participate in the defense of any claim, action or proceeding, including selection of defense counsel.
(b) Applications and approvals for tentative, parcel, and final maps. (1) A subdivider must, as a condition of tentative, parcel, or final map application and approval, defend, indemnify, and hold harmless the city and or its agents, officers, and employees from any claim, action, or proceeding against the city or its agents, officers, or employees to attack, set aside, void, or annul, an approval of the city, a city advisory agency, appeal board, or council concerning a subdivision. The city will promptly notify the subdivider of any claim, action, or proceeding and cooperate fully in the defense. (2) An applicant for a tentative, parcel, or final map must agree in the application to defend, indemnify, and hold harmless the city and its agents, officers, and employees as provided in subsection (b)(1).
(3) The conditions of approval for a tentative, parcel, or final map subdivision must recite the subdivider’s obligation in subsection (b)(1).
(4) The city may participate in the defense of any claim, action, or proceeding, and if it so chooses, will bears its own attorney’s fees and costs and defend the action in good faith. (5) The subdivider is not required to pay or perform any settlement unless the settlement is approved by the subdivider.
(6) Subsection (b) is to be interpreted and enforced in accordance with the limitations and requirements of Government Code Section 66474.9.
25

(c) Form of Indemnity. The city manager, in consultation with the city attorney, may determine the precise form of the indemnification in an application form and included in conditions of approval.
(d) Enforcement. To the fullest extent allowed by law, an applicant must indemnify the city for all of the city’s costs, losses, and attorney’s fees incurred to enforce the indemnification in this section.
(e) Applicant. “Applicant” means the party on whose behalf an application is submitted and any subsequent legal or equitable holder of a city approval. (f) Notice. Written notice of a claim, action or proceeding may be provided in accordance with Belmont City Code Section 1-12.
(g) Conditions of Approval. The conditions of an approval are to include reference to the applicant’s obligations under this section. Failure to include reference does not affect the applicant’s obligations under this section.

SECTION 3. BCC SECTION 22-31 AMENDED

Salson Trail Culvert Replacement Project - Staff Report.docx

STAFF REPORT
Meeting Date: May 13, 2025
Agency: City of Belmont
Staff Contact: Bozhena Palatnik, Public Works, (650) 595-7463, [email protected] Agenda Title: Salson Trail Culvert Replacement Project – Plans and Specifications Approval, Bid and Construction Award Authorization, Design Task Order Amendment, and Construction Management Task Order Authorization
Agenda Action: Resolution
Recommendation
Adopt a resolution approving plans and specifications, authorizing advertisement for sealed bids, authorizing the City Manager to negotiate and execute a contract with the lowest responsible and responsive bidder for an amount not to exceed $554,321 plus a ten percent construction contingency, approving a design task order amendment with Mott MacDonald Group, Inc. for an amount not to exceed $93,142, approving a task order for construction management services with MNS Engineers, Inc. for an amount not to exceed $90,655 for the Salson Trail Culvert Replacement Project, City Contract Number 2025-639; and appropriate budget funds to the Salson Trail Culvert Replacement Project.

Strategic Focus Area
Infrastructure and Mobility
Background
The Salson Trail is an unpaved fire road in the City of Belmont (City) located south of the Sugar Loaf Open Space area near East Laurel Creek Road. The trail provides recreation opportunities and important emergency access for firefighting to approximately 100 acres of open space area along the tributary of Laurel Creek. The open space is tightly surrounded by residential neighborhoods in the Cities of Belmont and San Mateo. During the large winter storm events of 2022/23 part of the trail that crosses the tributary with a 48” storm culvert was damaged by excessive flow and overtopped the crossing. The events caused erosion of the banks, caused much of the emergency access road to collapse, and jeopardized the sanitary sewer main.

The City has applied to the Federal Emergency Management Agency (FEMA) to repair areas impacted from these storm events, using $186,795 in federal grant funding available through the Hazard Mitigation and Public Assistance grant programs. However, FEMA has rejected City’s application for requested funding. Staff retained a qualified engineering firm to design improvements to fix the storm culvert, sanitary sewer main, and emergency access road, and provide clearance for all necessary regulatory permits. The design and permitting are now complete.

The Salson Trail Culvert Replacement Project will restore the culvert function, and adjoining infrastructure, and restore emergency access at the urban/wildland interface. 36

Salson Trail Culvert Replacement Project - Staff Report.docx Analysis
The Salson Trail Culvert Replacement Project aims to restore a critical piece of infrastructure at the urban/wildland interface by addressing both stormwater conveyance and emergency access needs. The project scope includes:
• Replacing and upsizing the failing culvert to mitigate the risk of future failures; • Replacing a damaged and at-risk segment of sewer main; and • Repairing and reopening the Salson Trail for emergency vehicle access and public recreational use.

Initial project assumptions anticipated exemption from environmental permitting requirements. However, upon early coordination with environmental agencies, only the U.S. Army Corps of Engineers confirmed that no permit would be required. In contrast, the Regional Water Quality Control Board and the California Department of Fish and Wildlife required full permit submittals. This triggered extensive coordination, additional review time, and added scope for the design consultant. As a result, staff is requesting an amendment to Task Order #1 with Mott MacDonald Group, Inc. to include environmental permit compliance, CEQA clearance, and post-construction restoration monitoring. The cost of Amendment #1 is $93,142, bringing the total Task Order #1 to $261,087.

To ensure effective construction oversight and regulatory compliance during the construction phase, staff solicited proposals from on-call construction management firms. MNS Engineers, Inc. was selected due to their proven experience with similar projects. Their construction management and inspection services are estimated at $90,655 and will include full-time inspection, coordination with permitting agencies, and managing field conditions and issues as they arise.

The total construction cost is estimated at $554,321, with a 10% contingency added to account for unexpected field conditions. Including the amended design contract and construction management services, the total estimated project cost is $787,351. To accommodate potential unforeseen costs, staff recommends that the City Council approve a total project budget of $810,000 for the Salson Trail Culvert Replacement Project (CIP #3233, Account #399-3-730-3233-9030), funded equally by Measure I (Fund 102) and the Belmont Fire Protection District (Fund 223), with each contributing $405,000.

The Bidder gave the City written notice within five working days, excluding Saturdays, Sundays, and state holidays, after the opening of the Bids of the mistake, specifying in the notice in detail the nature of the mistake and how the mistake occurred.

11. CITY’S DETERMINATION OF LOWEST RESPONSIBLE BIDDER

11.1. The term “Lowest Responsible Bidder” means the “Lowest Monetary Bidder” whose Bid is “responsive,” and who is “responsible” to perform the Work required by the Contract Documents, as those terms are defined by State law, including Public Contract Code Sections 20161, et seq, and 22030 et seq. This Section 11 summarizes the procedure by which the City will determine the “Lowest Responsible Bidder” in accordance with State law.

11.2. The City shall determine the “Lowest Monetary Bidder” on the basis of the Bid Amount, in accordance with the calculation criteria set forth on the Bid.

11.3. After the “Lowest Monetary Bidder” has been determined, the Lowest Monetary Bidder’s Bid will be evaluated by the Engineer in order to determine whether or not that Bid is “responsive.” The term “responsive” is defined by State law, but generally means that the Bid has been prepared and submitted in accordance with the requirements of the Bidding Requirements.

11.4. If the Lowest Monetary Bidder’s Bid is responsive, that Bidder’s qualifications will be evaluated by the Engineer to determine whether or not the Bidder is “responsible” to perform the Work 57 City of Belmont Contract Documents
Project: Salson Trail Culvert Replacement Project
City Contract Number 2025-639
Bidding Documents
Instructions To Bidders 7 of 9
required by the Contract Documents. The Engineer shall review “responsibility” of Bidders based upon the City’s analysis of the information submitted on the Bidder’s Statement of Responsibility (as a part of the Bid Forms) in accordance with the criteria set forth in Instructions To Bidders Section 12.

11.5. If the Engineer finds that the Lowest Monetary Bidder submitted a responsive Bid, and that the Bidder is responsible, then that Bidder will be deemed the apparent “Lowest Responsible Bidder”.

11.6. If the Engineer finds that the Lowest Monetary Bidder’s Bid is not responsive, or that the Lowest Monetary Bidder is not responsible, then the Engineer may review the responsiveness and responsibility of the next Low Monetary Bidder. If the Engineer finds that the next Low Monetary Bidder is responsive and responsible, then that next Low Monetary Bidder shall be deemed the apparent “Lowest Responsible Bidder. This process may continue until the Engineer finds the Lowest Monetary Bidder which is also responsive and responsible. In the event that one or more Low Monetary Bidders are found by the Engineer to be non-responsive or non-responsible, those Bidders will be given notice and a reasonable opportunity to present additional relevant evidence to the Engineer, within five working days after the Bidder receives the notice.

11.7. No Bid shall be binding upon the City until after the Contract is signed by both the Contractor and the City. The City may investigate the responsibility and qualifications of all Bidders to whom the award is contemplated for a period not to exceed sixty (60) days after the Bid opening. The sixty (60) day review period may be extended upon the written request by the Engineer and written approval by the affected Bidders.

11.8. Bid Protest. The City will issue a Notice of Intent to Award before the actual award. Any Bid protest must be submitted in writing to the Engineer before 5:00 p.m. of the fifth (5th) calendar day following posting of a Notice of Intent to Award for Construction in the City Hall Lobby. City will use reasonable efforts to deliver by email a copy of the Notice of Intent to Award to all Bidders who submitted Bids and provided an email address no later than one working day after its issuance, although any delay or failure to do so will not extend the Bid protest deadline described above. The following conditions will apply to all protests.

The initial protest document must be in writing, contain a complete statement of the legal ground for the protest; all the relevant facts to the protest; and the form of relief requested and the legal basis for such relief.

The protest must refer to the specific portion of the document that forms the basis for the protest.

The protest must include the name, address and telephone number of the protesting party or the person representing the protesting party. If an email address is available, it should also be included.

The party filing the protest must concurrently transmit a copy of the initial protest document and any attached documentation to all other parties with a direct financial interest that may be adversely affected by the outcome of the protest.

Instructions To Bidders 8 of 9
The procedure and time limits set forth in this paragraph are mandatory and are Bidders sole and exclusive remedy in the event of Bid protest. Bidders failure to comply with these procedures shall constitute a waiver of any right to further pursue the Bid protest, including filing a Government Code Claim or legal proceedings.

The City will respond to any properly submitted protest within fifteen (15) calendar days and shall provide a hearing to the protesting bidder but only if the hearing is requested by the protesting bidder in the protest. The City’s decision on the protest shall be final.

12. CITY’S DETERMINATION OF RESPONSIBILITY

12.1. The term “responsible” is defined by California law, but generally means that the Bidder is able to demonstrate that it possesses: (1) the capacity to perform the Work required by the Contract Documents with respect to financial strength, resources available, and experience; and (2) the integrity and trustworthiness to complete performance of the Work in accordance with the Contract Documents. The City may consider the following factors, in relation to the Work to be performed for this Project, in determining whether nor not a Bidder is “responsible”:

Demonstrated financial strength including, but not limited to, resources available, bonding capacity, and available insurance.

Demonstrated safety record including, but not limited to, Experience Modification Rate.

Successful completion of projects of similar scope and size. In reviewing this factor, the City may consider elements including, but not limited to, contract amount of completed projects, experience on public works projects, experience implementing prevailing wage certified payroll requirements, timeliness of performance, and, if necessary, evaluation of Bidder’s work by previous cities, clients, design professionals, or subcontractors.

Sufficiency of contract administration and construction management systems including, but not limited to, proposed scheduling tools, proposed subcontract forms, proposed progress payment applications, and proposed certification of payroll documents.

History of claims, litigation, and termination or disqualification from projects.

12.2. The City will make its determination of responsibility based upon information submitted by Bidders contained in the “Bidders Statement of Responsibility,” included in the Bid Forms, and, if necessary, interviews with previous cities, clients, design professionals, or subcontractors with whom the Bidder has worked. If a non-responsive or non-responsible Bidder submits additional evidence pursuant to Instructions To Bidders Section 11, then that additional evidence shall be considered by the Engineer in making a determination of the Lowest Responsible Bidder.

13. AWARD OF CONTRACT

13.1 After the determination as to which Bidder is the Lowest Responsible Bidder, the City will issue a Notice of Award to the Lowest Responsible Bidder. No contractor or subcontractor may be awarded a contract for the project (awarded on or after April 1, 2015) unless registered with the Department of Industrial Relations under Labor Code section 1725.5.

The Standard Specifications for Public Works Construction “Greenbook” (2018) in conjunction with The State of California Department of Transportation Standard Specifications “Caltrans Standard Specifications” (2023 Edition) shall be the referenced standard specifications for this contract. All work shall conform to the aforementioned standard specifications, including General Conditions, Special Provisions and Technical Specifications, unless otherwise specified in the Contract Documents.

G.C. 2 DEFINITIONS
“City of Belmont,” the “Contractor,” and the “Contract Documents” are identified in the Standard Contract Agreement. The “City of Belmont” and the “Contractor” include their authorized representatives and are treated throughout as if each were singular in number and neuter in gender. “Contractor” includes its surety. Whenever in the Standard Specifications and Contract Documents the following terms are used, they shall be understood to mean and refer to the following:

A. Agency/City The City of Belmont, California
B. Engineer The Director of Public Works and his authorized representatives.

G.C. 3 ENGINEER
The Engineer shall act as the City’s representative during the construction period. He shall determine the amount, quality, acceptability and fitness of parts of the work and interpret the Contract Documents. The Engineer will make visits to the site and determine if the work is proceeding in accordance with the Contract Documents. No act or omission of the Engineer shall relieve the Contractor of the duty to proceed with the work in strict conformity with the Contract Documents.

At least one week prior to the start of work, the Contractor shall furnish to the Engineer a Schedule of Work showing the Contractor’s planned sequence of operations. Such schedule shall be subject to the review and approval of the Engineer. No work shall be done until the Contractor and the Engineer have agreed to the schedule to be followed by the Contractor.

Upon request, the Engineer shall reduce to writing any oral order, objection requirement or determination. All communications to the City by the Contractor shall be via the Engineer.

The Contractor shall hand deliver written notification to the Engineer prior to any emergency overtime, weekend or holiday. The sum of the City Inspector’s pay for inspection of overtime weekend or holiday work performed will be deducted from any moneys due to the Contractor. 102
Overtime is defined as work in excess of 8 hours in a day. The Contractor, and not the Engineer, shall be responsible for the construction means, controls, techniques, sequences, procedures and construction safety.

As stated elsewhere, amounts shown in the Proposal and Contract as to quantities are estimates only. From time to time, the Engineer shall direct the Contractor as to the prosecution of the work in such manner as to increase or decrease such estimates as to the work actually to be done. The Contractor shall comply with such instructions and shall be paid only for work actually done based on the unit prices set out in the Contract.

G.C. 4 AWARD AND EXECUTION OF CONTRACT
The right is reserved to reject any bids if the Engineer is not satisfied that the bidder is fully qualified to carry out the terms of the Contract.

G.C. 5 PROTECTION
At his expense the Contractor shall:

G.C. 6 VALUE ENGINEERING
The City is receptive to proposals from the Contractor identifying ways to reduce project costs and will share 50% of the cost savings with the Contractor if the proposal is accepted. The City encourages the Contractor to submit cost saving proposals on construction methods, products or materials that are equal to, or better than, what is specified by the project plans or specifications.

The City is not obligated to accept and implement the proposal; however, if the City does accept the proposal for implementation, the City will share 50% of the cost savings with the Contractor.

The cost savings shall be limited to the project for which the proposal is made. The City retains the right to implement the Contractor’s proposal on future projects without obligation to sharing the future cost savings. The cost saving/value engineering program is administered by the City in accordance with California Public Contract Code Section 7101.

G.C. 7 CHANGES IN THE WORK
The City shall have the right to make any reasonable changes in the project plans or quantities determined to be necessary or expedient. In case such changes increase or diminish the work shown, the Contractor shall be paid for the work actually done at a mutually agree upon adjustment to the Contract price, based upon the accepted Bid Proposal or according to the provisions of Paragraph 7, Changes in Work. The Contractor shall not be entitled to extra payment, nor shall any claim be made on account of anticipated profits on the work that may be omitted.

G.C. 8 CHANGES IN CONTRACT PRICES
Whenever corrections, alterations, or modifications of the work under this Contract are ordered by the Engineer and increase the amount of work to be done, such added work shall be known as extra work; and when such corrections, alterations, or modifications decrease the amount of work to be done, such subtracted work shall be known as work omitted.

The difference in cost of the work affected by such change will be added to or deducted from the amount of said Contract price, as the case may be, by a fair and reasonable valuation, which shall be determined in one or more of the following ways:
a. By agreed lump sum
b. By agreed unit prices
c. By Force Account
If neither a nor b methods can be agreed upon and the Contractor receives written order to make such changes, the Contractor shall be compensated by Force Account for his actual necessary costs, including labor, material, and equipment rental, as determined by the Engineer, plus a negotiated 104
fixed fee for profit and such overhead items as home and branch office expenses, general expenses, general superintendence, indirect labor, and licenses. The negotiated fixed fee shall not exceed fifteen percent (15%) of actual necessary direct costs.

In addition to the actual cost of labor, the amount due the Contractor shall include the cost of compensation insurance, contributions made to the State as required by the provisions of the Unemployment Reserve Act, Chapter 352, Statutes of 1935, as amended; and for taxes paid the Federal Government, as required by the Social Security Act, approved August 14, 1935, as amended to date, plus other payments the Contractor must make to, or on behalf of, the workers.

For use of equipment owned by the Contractor, the rental rates therefore shall be based upon the current prices prevailing in the locality, not to exceed the rates promulgated by the California (State) Department of Transportation in effect at the time the work was performed.

It is understood that labor, materials, and equipment may be furnished by the Contractor, or by the subcontractor, or by others on behalf of the Contractor. When the work is performed by other than the Contractor’s organization, the Contractor shall reach an agreement with such other forces as to the distribution of payments made for such, and no additional payment therefore will be made by the City.

When Force Account work is performed by a bona fide and approved subcontractor, the negotiated fixed fee markup is limited to ten percent (10%) for the subcontractor, and five percent (5%) for the prime Contractor, on the performing subcontractor’s actual costs, and no markup will be allowed for any intermediary subcontractor between the performing subcontractor and the prime Contractor.

All labor furnished on Force Account work shall be adjusted daily upon report sheets, furnished by the Contractor and signed by both parties, which daily report sheets hall thereafter by considered the true record of Force Account labor provided.

In order that a proper estimate may be made by the Engineer of the net cost of labor and materials entered into Force Account work, in accordance with the procedure hereinbefore stated, the Contractor shall furnish weekly an itemized statement of materials and labor supplied together with the cost of such material and the wages paid, and shall furnish vouchers for quantities and prices of such labor, material, or work. In case the Contractor fails to comply with the above provisions, he shall have no claim for compensation against the City.

City reserves the right to contract with any person or firm other than the Contractor for any or all extra work. The Contractor’s attention is especially called to the fact that he shall be entitled to no claim for damages for anticipated profits on any portions of work that may be awarded to others.

When the Contractor considers that any changes ordered involve extra work that the Engineer has not recognized as such, he shall immediately notify the Engineer in writing as to when and where alleged extra work is to be performed. If the Engineer directs by written order that the alleged extra work be performed, the Contractor shall comply, and shall make claim for compensation therefore each month not later than the 20th day of the month during which the work claimed to be extra work was performed, and he shall submit a weekly complete statement of materials used and expenses incurred on account of extra work performed, showing allocation of all materials and expenses. All such claims shall state the date of the Engineer’s written order. 105
Unless such notification is made in writing and unless complete statements of materials used and expenses incurred on account of such alleged extra work are furnished as above required, the Contractor shall not be entitled to consideration for payment for alleged extra work, and any future claims for compensation for such alleged extra work shall be invalidated.

G.C. 9 BRAND OR TRADE NAME - SUBSTITUTE OF EQUALS
Reference is made in Section 3400 of the California Public Contracts Code, which is by this reference incorporated herein with like effect as if here set forth in full.

If a potential bidder believes he knows of an equal to a specified brand or trade name which is not mentioned in the Contract Documents, then such potential bidder may so advise the Engineer of such fact, giving all relevant information. If appropriate, an Addendum will be issued as to the alleged equal provided that such issuance may be accomplished at least 5 days before the time fixed for opening bids.

Unless the subject article or product is expressly designated for matching others in use in a particular public improvement either completed or in the course of completion, any bidder may, as part of its bid proposal, include a request for substitution of an item equal to any specified brand or trade name. At the preconstruction meeting, the Contractor may submit to the Engineer data substantiating such a request, and the difference, if any, in cost. The Engineer shall promptly investigate the request and make a recommendation to the City as to equality.

The City shall promptly determine where the substitute is equal in every respect to the item specified, and approve or deny the request accordingly, and shall notify the Engineer of the determination made, who shall advise the Contractor in writing of the decision. Unless the request is granted, substitution will not be permitted. In accordance with Section 3400 of the California Public Contracts Code, the Contractor shall be provided a period of not less than 35 days after the award of contract for submission of data substantiating a request for a substitution of “an equal” item.

Nothing herein shall authorize a change in the Contract price or prevent the use of change order in the manner provided elsewhere in the Contract Documents.

G.C. 10 FINAL INSPECTION, ACCEPTANCE AND NOTICE

OF COMPLETION
Upon written notice from the Contractor that the entire work required by the Contract Documents is complete and that all submittals required by him are made, and after the Contractor has delivered the bonds, certificates of inspection, proof of insurance, guarantees, warranties, releases, and other documents, all as required by the Contract Documents or by law, a post construction conference will be held to review the work and resolve any unsettled matters. Present at the conference shall be the Engineer, the Inspector, the Contractor, and the Contractor’s Superintendent. Following this conference, Engineer will make a final inspection, the Contractor, and the City will notify the Contractor in writing of any deficiencies in the submittals and other documents required of him.

The Contractor promptly shall make such corrections as are necessary to remedy all defects or deficiencies. After the Contract has completed any such corrections to the satisfaction of the City, the City will issue a written final acceptance of the work and file any notice of completion required by law or otherwise.
106
Final Inspection will be in two phases: a semi-final inspection by the Construction Inspector and the Contractor; and a final inspection, including representatives of the City, the Contractor, and any State or County agency. At the conclusion of the semi-final inspection, the Construction Inspector will provide the Contractor, in writing, a “punch list” of items requiring completion of remedial work. The Contractor shall rectify all matters on the “punch list” before making his formal request, in writing, for Final Inspection. Upon completion of the final inspection, if further completion or remedial work is determined to be necessary, the Engineer shall transmit to the Contractor a final list of items for remedial attention. After final inspection, the City Council will adopt a resolution determining that the contract work, or designated phases thereof, is substantially complete and is accepted.

G.C. 11 GUARANTEE AND WARRANTY OF WORK
The Contractor shall submit all products and materials to be used to the Engineer for approval. The Contractor shall provide a list of submittals at the pre-construction conference.

Notwithstanding inspections and acceptance by the City of work furnished under this contract, the Contractor warrants to the City that all materials and equipment furnished under the contract, including that provided pursuant to change orders, will be of good quality and new, that the work will be free from defects in material or workmanship and that the work will conform to the requirements of the Contract Documents. Work not conforming to these requirements, including substitutions not properly approved and authorized, may be considered defective.

This warranty by the Contractor is in addition to any warranties or guarantees required by the special provisions or technical specifications for specified items of equipment or materials. This warranty shall be in effect notwithstanding any disclaimers, or limiting or conditional terms contained such separate warranties furnished by manufacturers or suppliers.

If, within one year after the date of final acceptance of the work by the City, any of the work is found not to be in accordance with the Contract Documents the Contractor shall correct it promptly after written notice from the City to do so, and pay for any damage to other property resulting from such non-conforming work. If the Contractor fails to make the repairs or replacements promptly, or in any emergency when delay could cause risk or damage or loss, the City may have the nonconforming work removed, replaced or corrected at the expense of the Contractor and his surety.

If the amount of the performance bond is insufficient to cover such work, the Contractor shall be liable to pay any such deficiency on demand by the City. Nonconforming work which is remedied under this Section shall be subject to an extended warranty obligation for a period of one year after the non-conforming work has been remedied.

All workmanship performed, and materials/equipment installed, as part of this contract shall be guaranteed for a period of one year, commencing upon issuance of the Notice of Completion for the work under this contract.

G.C. 12 CITY’S RIGHT TO STOP WORK OR TERMINATE THE CONTRACT The City, without prejudice to such other right, remedy or relief it may be entitled to, may by giving ten (10) days notice to the Contractor, terminate the employment of the Contractor and it his right to proceed, if:

A. The Contractor shall be adjudged bankrupt or make an assignment for the benefit of creditors.
107
B. A receiver or liquidator is appointed for the Contractor or any of its property.

C. The Contractor shall refuse or fail after Notice of Warning from the City by the Engineer to supply sufficient properly skilled workmen or suitable materials.

D. The Contractor fails to prosecute the work with such diligence as will insure its completion within the stipulated time period.

E. The Contractor shall fail to make payments to persons supplying labor or materials for the work.

F. The Contractor does not comply with applicable law or instructions of the Engineer.

G. The Contractor is otherwise guilty of a substantial violation of any provision of the Contract Documents.

If the City determines that the Contractor has failed to perform any of its obligations under the Standard Contract Agreement or to otherwise comply with the Standard Contract Agreement, then, in addition to all other remedies provided by law, City may terminate the Standard Contract Agreement immediately upon written notice to the Contractor provided, however, that if the City’s determination of the Contractor’s failure to perform under or comply with the Standard Contract Agreement can be cured by Contractor within thirty (30) days from the date that City discovers Contractor’s failure to perform or comply, then the City may provide Contractor with a notice of Contractor’s failure to perform or comply and provide Contractor with a definite period of time, to be specified in the notice and not to exceed a maximum period of thirty (30) days from the date of the notice, to cure. Failure to perform or comply to City’s satisfaction within the definite time period specified in the notice are grounds for termination by City.

The City Manager is empowered to terminate the Standard Contract Agreement and issue the notices provided for in this Section on behalf of City. In the event of termination, the Contractor shall immediately cease all work being performed under the Standard Contract Agreement.

Termination of the Standard Contract Agreement by City shall constitute the withdrawal of any consent or authorization of City for Contractor to perform any construction or other work under the Standard Contract Agreement in the public right-of-way or on public property, excepting only that work necessary to leave all work site areas in a clean and safe condition.

The City’s right to terminate may be for the entire work, or at the City’s option, as to any portion thereof as to which delay shall have occurred or breach or miscompliance related, and may thereupon take possession of the entire work or portion thereof. In such case, the Contractor shall not be entitled to receive any further payment until the work is finished. If the unpaid balance shall exceed the expense of completion, and other damage, expense or loss of the City occasioned by the Contractor’s failure to properly perform, the Contractor shall pay such excess. If such expense and damage exceeds the unpaid balance, the Contractor is liable to the City for the excess. If the City elects to proceed under this Section, it may take possession of and utilize in completing the work such materials, supplies, pain and equipment on site which may be necessary or convenient for the purpose of completing the work. The City is expressly granted the right, acting via an Engineer or otherwise, to operate equipment and machinery on site for the purpose of determining whether it has a basis for proceeding under this Section. 108
G.C. 13 PAYMENT AND MONTHLY ESTIMATES

1. Schedules, Reports and Records As stated in Section 9-2 of the Standard Specification for Public Works Construction “Greenbook” (latest edition), the Contractor is required to submit to the Engineer for approval, a schedule of values for bid items. Lump Sum bid items are to be broken out into appropriate segments to create the schedule. This is to be integrated with the project work schedule and submittal schedule. These schedules will be used in the evaluation of Contractor Progress Payment Requests to the City.

2. Pay Period On or immediately after the first day of each month, the Contractor is to submit to the Engineer a “Request For Progress Payment.” This request is to be for work performed and for materials on the site up to and including the last day of the month. The Request For Progress Payment is to be submitted on a “Payment Application and Certificate” form (CP-14).

3. Retentions Pursuant to Section 9-3.2 of the Specifications, 5 percent of each month’s amount earned by the Contractor will be retained by the City until 50 percent of the contract work is completed. At that point, at the Engineer’s discretion, if work is proceeding satisfactorily, retention may be discontinued except for the amount previously retained. Pursuant to Section 9-

3.2 of the Standard Specification for Public Works Construction “Greenbook” (latest edition), the Contractor may elect to place sufficient acceptable securities with the City or in an escrow account, in lieu of the Engineer’s retention of the funds. Earnings from such an escrow account shall accrue to the benefit of the Contractor. All procedures and documentation shall be as provided by State Law.

4. Preparation and Processing of Monthly Progress Payment Requests Each monthly progress payment shall be submitted on a copy of the form “Payment Application and Certificate” (CP-14).

It shall be prepared and certified by the Contractor and submitted to the Engineer, on or immediately following the last day of the month. It shall include the Contractor’s itemization, prepared in a format approved by the Engineer and including the approved schedule of values. The “Payment Application and Certificate” (Form CP-14) shall be signed by an authorized representative of the Contractor.

Preparation of the request for progress payment should be preceded by consultation between the Contractor and the Engineer to determine acceptable percentages of completion for items in the Schedule of Values for which work has been performed. The extension of the total amount due per Schedule Item should agree with the percentage of completion. This may necessitate expressing the percentage figure to four decimal places.

Pursuant to Section 9-3.3 of the Specifications, requests for payments for materials on the site shall be accompanied by invoices, bills of sale, delivery tickets or other documentation that establishes the City’s title and the value of materials for which payment is requested.

Requests for payment of Change Orders authorized by the City shall be accompanied by signed daily work orders for labor, equipment and materials if performed on a time and material basis.

These are to be submitted on “Cost of Work Record” forms (CP-18).

The Engineer will review the request, check all mathematical entries, percentages and extension, and when satisfactory, will transmit the Form CP-14 to the Director of Public Works with recommendation for payment. Upon approval, the Engineer will submit, the progress payment 109
request to the City’s Finance Department for payment to the contractor. Payment will then be issued to the Contractor by the City, with retention of a portion of the funds by the City, as indicated above. If a retention securities escrow account has been established, the City will make 100% payment of the approved monthly progress payment.

Upon satisfactory completion of the Contract work, and official acceptance by the City, the retained amount will be paid to the Contractor by City, or the City will authorize the release of impounded securities to the Contractor, all subject to the provisions of Section 9-3.1 of the Specifications.

G.C. 14 FAILURE TO COMPLETE THE WORK IN THE TIME AGREED UPON
It is agreed by the parties to the Contract that time is of the essence; and that in the case all the work is not completed before or upon the expiration of the time limit set forth, damage will be sustained by the City and it is, therefore, agreed that the Contractor will pay to the City as damages the amount of the actual damage as determined, due to the failure to complete the work in the time agreed upon. In addition, the City shall have the right to charge to the Contractor and to deduct from payments for the work the actual cost to the City of engineering, inspection, superintendence, and other overhead expenses, which are directly chargeable to the contract and which accrue during the period of such delay, except that the cost of final surveys and preparation of the final estimate shall not be included in such charges. The expenses and damages described above shall be deducted from any money due the Contractor under this contract; the Contractor and his sureties shall be liable for any such excess cost.

The Contractor shall not be deemed in breach of its contract and no forfeiture due to delay shall be made because of any delays in the completion of the work due to unforeseeable causes beyond the control and without the fault or negligence of the Contract, provided the Contractor requests an extension of time in accordance with the procedures set forth in Section 6-6 of the Standard Specification for Public Works Construction “Greenbook” (latest edition). Unforeseeable causes of delay beyond the control of Contractor shall include acts of God, acts of a public enemy, acts of the government, fires, floods, epidemics, quarantine restrictions, strikes, freight embargoes, and weather, or delays caused by failure of the City or the owner of a utility to provide for removal or relocation of existing utility. Failure of the Contractor, its agent, servants, employees, officers, subcontractors, directors, or of any party contracting to perform part or all of the work or to supply any equipment or materials shall not be excusable delays. Excusable delays (those beyond Contractor’s control) shall not entitle the Contractor to any additional compensation. The sole remedy of the Contractor shall be to seek an extension of time.

G.C. 15 FINAL ACCEPTANCE, RECORDING AND PAYMENT
Upon satisfactory completion of the contractor work or designated phase thereof, and receipt, by the City, of required releases and the “Contractor’s Certificate of Release and Request for Final Payment” (CP-20), the acceptance process is as follows:

1. The Engineer recommends to the City Manager and the City Council that the contract work, or designated phase thereof, is substantially complete and ready for acceptance by the City. 110

2. The City Council adopts a resolution determining that the contract work, or designated phases thereof, is substantially complete and is accepted. The resolution directs the City Clerk to do the following:
(a) Issue a “Notice of Substantial Completion” (Form CP-21) to the Contractor. (b) File with the County Recorder of the County of San Mateo a “Notice of Completion of Contract” (Form CP-22). Filing not to occur until after certification by the Engineer to the City Clerk that all required “punchlist” items have been satisfactorily remedied by the Contractor. On the date established in the “Notice of Completion” the Contractor’s required one-year warranty period will commence, and the City will assume operational responsibility for the completed facilities.

3. Upon issuance of the “Notice of Substantial Completion” to the Contractor, the City will make final payment to the Contractor of the amount remaining after deducting all prior payments and deducting all amounts to be kept or retained by City under the provisions of the contract documents.

4. If all “punch list” items have been satisfactorily remedied, then within ten days of the City Council adoption of the resolution determining the contract work, or designated phase thereof, completed and accepted, the City Clerk will file with the County Recorder the “Notice of Completion of Contract.” If a “punchlist” of remedial work remains to be performed by Contractor, then provisions of Section 2.b, above, shall govern as to the time of filing the “Notice of Completion of Contract.”

5. A period of thirty-five (35) calendar days will elapse from the date of filing of the “Notice of Completion of Contract” with the County Recorder before the final payments of retained amounts will be made to the contractor.

6. If no stop notices are received by the City within the stated 35-day filing period, the City will issue final payment of retained amounts for the contract work, or designated phase thereof, to the contractor. If any stop notice is received by the City within the 35-day waiting period, it will be referred to the City’s legal counsel and final payment of retained amounts will be deferred or adjusted in accordance with advice of legal counsel, until such stop notice matter has been satisfactorily resolved.

G.C. 16 RESOLUTION OF DISPUTES
The City of Belmont incorporates the provisions of Chapter 1414 of the State Public Contract Code (A.B. No. 4165) as part of its plan and specifications for the resolution of construction claims through arbitration. A summary of its provisions are included in the modification to the Standard Specifications which the Contractor is directed to read. The Contractor is also directed to review the entire Statute, Chapter 1414, Section 20207.4 and Section 20104 of the Public Contract Code.

The City’s records setting forth the fair and reasonable cost of repairing, replacing, rebuilding or reasonable cost of repairing, replacing, rebuilding or restoring any damage or defects when performed by one other than the Contractor shall be binding and conclusive as to the amount thereof upon the Contractor.
111
G.C. 16.1 CONTRACT INTERPRETATION BY THE ENGINEER
Questions regarding the meaning and intent of the Contract Documents shall be referred in writing by the Contractor to the Engineer. The Engineer will respond to the Contractor in writing with a decision.

G.C. 16.2 CLAIMS
G.C. 16.2.1 NOTICE
If the Contractor disagrees with the Engineer’s decision in G.C.16.1, Contract Interpretation by the Engineer, or in any case, where the Contractor deems additional compensation or a time extension to the contract period is due him for work or materials not covered in the contract or which the Engineer has not recognized as extra work, the Contractor shall notify the Engineer, in writing, of his intention to make claim. Claims pertaining to decisions provided in G.C.16.1 shall be filed in writing to the Engineer within five (5) days of receipt of such decision. All other claims notices for extra work shall be filed in writing to the Engineer prior to the commencement of such work.

Written notice shall use the words “Notice of Potential Claim.” Such Notice of Potential Claim shall state the circumstances and the reasons for the claim, but need not state the amount.

Additionally, no claim for additional compensation or extension of time for a delay will be considered unless provisions of G.C.7, Changes in the Work; G.C.8, Changes in Contract Prices; and G.C.25, Termination of Contract by Contractor of these General Conditions, are complied with. No claim filed after the date of final payment will be considered.

It is agreed that unless notice is properly given, the Contractor shall not recover costs incurred by him as a result of the alleged extra work, changed work or other situation which had proper notice been given would have given rise to a right for additional compensation. The Contractor should understand that timely notice of potential claim is of great importance to the City, and is not merely a formality. Such notice allows the City to consider preventative action, to monitor the Contractor’s increased costs resulting from the situation, to marshall facts, and to plan its affairs. Such notice by the Contractor, and the fact that the Engineer has kept account of the cost as aforesaid, shall not in any way be construed as proving the validity of the claim.

G.C. 16.2.2 SUBMISSION OF CLAIM COSTS
Within thirty (30) days after the last cost of work for which the Contractor contends additional compensation is due, but if costs are incurred over a span of more than 30 days, then within fifteen (15) days after the thirtieth day and every month thereafter, the Contractor shall submit to the Engineer the costs incurred for the claimed matter. Claims shall be made in itemized detail satisfactory to the Engineer in content, detail and format of presentation. If the additional costs are in any respect not knowable with certainty, they shall be estimated. If the claim is found to be just, it shall be allowed and paid for as provided in G.C.7, Changes in the Work.

G.C. 16.2.3 CLAIM MEETINGS
From time to time the Engineer may call special meetings to discuss outstanding claims. The Contractor shall cooperate and attend, prepared to discuss outstanding claims, making available the personnel necessary for claim resolution, and providing documents reasonably requested by the Engineer.
112
G.C. 16.3 RESOLUTION OF CLAIMS
For all contracts awarded during the effective dates of Public Contract Code Section 20104, where claims cannot be resolved between the parties, claims for three hundred and seventy-five thousand ($375,000) or less shall be resolved pursuant to the provisions of that code section, which is summarized in G.C.16.3.1 and 16.3.4 are applicable; however, G.C.16.3.5, Civil Action for claims less than $375,000 is not applicable.

G.C. 16.3.1 CLAIMS LESS THAN $50,000

1.

a. Design each member or support element to support the maximum lateral earth pressures, hydrostatic pressures, lateral loads from traffic, construction equipment, and spoils loads that can occur during construction with appropriate safety factors.
b. Design the support system to prevent raveling, running, and flowing of excavation walls and associated loss of adjacent ground and adjacent ground surface settlement or existing trench material at utility crossings. Design the support system to retain non-cohesive granular soils subject to raveling, flowing, and/or running upon vibration from construction equipment including compaction of backfill. c. Prevent heave and/or piping (boiling) of the excavation bottom.

d. Design excavation support systems in accordance with all CAL/OSHA, and OSHA, requirements.
e. Take into account all surcharge loadings. Surcharge loadings can be due to such items as material or soil stockpiles, sloping ground adjacent to shoring, and adjacent building foundations. Contractor shall assure that his assumed conditions and loadings are not exceeded in the field during construction.
f. Design shoring to withstand any construction loading. g. The design of shoring shall conform to accepted engineering practice in this field. The Engineer’s approval of the Contractor’s plans and methods of construction does not relieve the Contractor of his responsibility for the adequacy of this support.
173
B. Performance Criteria:

1. The Contractor shall be solely responsible for, and bear the sole burden of cost for, any and all damages resulting from improper shoring or failure to shore.

2. The safety of workmen, the protection of adjacent structures, property and utilities, and the installation of adequate supports for all excavations shall be the sole responsibility of the Contractor.

3. The design, planning, installation, (and removal, if required) of all shoring shall be accomplished in such a manner as to maintain stability of the required excavation and to prevent movement of soil and rock that may cause damage to adjacent shoring systems, structures and utilities, damage or delay the work, or endanger life and health.

Repair holes, rips and voids in the impermeable plastic membrane with commercial-quality waterproof tape. Replace impermeable plastic membrane when patches or repairs compromise the impermeability of the material.

Repair TCDS within 24 hours after the damage occurs.

Prevent debris from entering the TCDS and receiving water.

Remove and immediately replace gravel, gravel-filled bags, impermeable plastic membrane, or plastic pipes contaminated by construction activities.

Remove sediment deposits and debris from the TCDS as needed. If removed sediment is deposited within project limits, it must be stabilized and not subject to erosion by wind or water, under sections 19-1.01 and 19-2.03 B.

3.03 Removal
When no longer required, remove all components of TCDS. Return the creek bed and banks to the original condition.

Do not excavate the native creek material. Backfill ground disturbance, including holes and depressions caused by the installation and removal of the TCDS with gravel. Maintain the original line and grade of the creek bed.

1 City of Belmont – Salson Trail & Culvert
Project Description
Introduction
This document describes the City of Belmont’s (City’s) proposed Salson Trail and Culvert Project (project, proposed project), located at the northwest edge of the City adjacent to Sugarloaf Open Space (Figure 1). It contains the following information.
• Background on the project including the project’s context, the need for the project, and the project goal and objectives
• Information on previous studies that provided the basis for project design • A description of the project elements
• An overview of the anticipated construction process
• The environmental commitments that will be put in place to avoid and reduce impacts on sensitive habitats and special-status species
• Information on project environmental review and clearance needs A list of References Cited follows the text.

Project Context
The project is located at the interface between hillside residential development and open space (Figure 2).

Salson Trail is an unpaved fire road that provides important emergency firefighting access to the open space as well as supporting recreational use by hikers and bicyclists. It also provides maintenance access to a 10-inchdiameter vitrified clay pipe (VCP) City sewer main that serves approximately 400 houses in the adjacent residential area to the south.

As a hillside road notched into the slope, Salson Trail crosses multiple drainages, including a headwaters tributary to East Laurel Creek, which is culverted beneath the trail about 140 feet east of the terminus of paved East Laurel Creek Road. East Laurel Creek, which flows northeast, is the largest tributary of Laurel Creek; Laurel Creek in turn flows generally southeast, ultimately discharging to San Francisco Bay via Seal Slough.1 During the large storm events of December 2022 – January 2023, the Creek overtopped Salson Trail, eroding out a portion of the road and severely damaging the existing 48-inch-diameter corrugated metal pipe (CMP) 1 Seal Slough is also referred to as O’Neal Slough (see Figure 1).

culvert conveying East Laurel Creek flows (Figure 3). The north end of Salson Trail has been closed since that time to reduce risks to public safety (see https://www.belmont.gov/Home/Components/FacilityDirectory/ FacilityDirectory/96/35). The segment of the existing sewer main that crosses the culvert in the subsurface (about 50 linear feet in total) is also damaged and requires replacement to prevent leaks and spills.

Project Objectives
The Salson Trail & Culvert Project is proposed to restore culvert function, prevent sanitary sewer spills, and restore firefighting access at the urban/wildland interface.

Specific project objectives include
• replacing the failing culvert at an appropriate diameter • replacing the damaged and at-risk segment of sewer main • repairing Salson Trail so it can be reopened for firefighting access and recreational use Basis of Design
Project design was largely guided by a hydrologic and hydraulic (H&H) analysis conducted by Wood Rodgers for the City (Wood Rodgers 2024; separately attached). This entailed developing an H&H model for the channel and culvert, assessing the capacity and function of the existing culvert crossing under 10-, 25-, and 100-year storm conditions, and recommending improvements based on modeling results. Modeling used a refined version of the H&H model previously developed for the City’s Drainage Master Plan (Wood Rodgers 2024).

Wood Rodgers’ (2024) modeling indicates that the existing 48-inch-diameter culvert is undersized for flows generated by the 25-year storm and larger events. They accordingly recommended upsizing the culvert to 60- inch diameter, to safely convey the 25-year flow without overtopping and roadway erosion. They also identified that the existing 48-inch-diameter CMP culvert is corroded, presumably due to soil conditions, and recommended that the replacement culvert be constructed of reinforced concrete pipe (RCP) to extend its service life. Other recommendations included placement of riprap at the new culvert inlet and outlet to stabilize the channel and minimize erosion at higher flows (Wood Rodgers 2024).

Additional evaluation during the early phases of the design process determined that a headwall with wingwalls would be a better solution for retainment of the embankment and road section of the unpaved trail and this was substituted for the upstream riprap apron (Samudrala pers. comm., Mott MacDonald 2024a). The 12-foot height of the wingwalls (see Mott MacDonald 2024a) was based on the existing Salson Trail roadway grade (Abad pers. comm.), and the wingwalls are being designed consistent with California Department of Transportation (Caltrans) Standard Plan, 2023 Edition, Standard Details B3-1C and D90 (again, see Mott MacDonald 2024a).

Further modeling using an add-on to the same model construct was conducted to determine the appropriate size for riprap at the downstream end of the culvert and the extent of the riprap apron (Wood Rodgers 2024).

Inputs included the 25-year design flow, culvert diameter (60 inches), normal depth, flow type, and culvert tailwater depth, which was obtained from the downstream channel cross section. Once D50 (the average riprap diameter) was determined, the length and depth of the downstream riprap apron were calculated using the approach laid out in FHWA Engineering Circular 14 (Federal Highway Administration 2006). Apron width was determined using a 1:3 flare slope conforming to the dimensions of the downstream channel. A headwall without 246

3 wingwalls would also be included on the downstream end of the culvert, to provide a stable section for the Salson Trail roadway and ensure that it can adequately support emergency vehicles for firefighting access.

A trash rack was also recommended for the inlet to reduce the potential for culvert clogging and damage due to floodborne debris (Wood Rodgers 2024).2 Preliminary design evaluation found that a row of “debris catcher” poles similar to those used on the City’s 2011 Bartlett Way culvert replacement (Place ID No. 772163) would be more appropriate than a trash rack per se and these will be substituted for the trash rack.

Finally, Wood Rodgers (2024) recommended placement of an aggregate base for restoration of the roadway, to improve wet weather access.

Project Overview
Project Elements
As currently proposed, the project would include the following elements (Figure 4) (Mott MacDonald 2024a, 2024b).
• A new 60-inch-diameter RCP culvert
• Headwall, wingwalls, and “debris catcher” poles at the upstream end of the culvert • Headwall and riprap apron at the downstream end of the culvert • Replacement of the damaged section of 10-inch-diameter sewer line with high-density polyethylene (HDPE) pipe at the same diameter
• Restoration of the Salson Trail where it was damaged by floodflows The current (October 2024) progress planset is included as a separate attachment with this permit application.

Project Construction
Figure 4 shows the anticipated work area. Construction would rely on means and methods typical in the San Francisco Bay Region. Equipment expected to be in use on the site includes an excavator, concrete mixer, dump truck(s), bulldozer, and compactor as well as hand tools and crew vehicles. Staging would be accommodated entirely within the closed section of Salson Trail. Access to the site would be via Salson Trail, entering either from Bishop Road on the west or East Laurel Creek Road on the east.

Construction would entail the following steps.
• Site preparation; clearing and grubbing of vegetation in the immediate work area • Using sump pumps and a temporary pipeline extending from manhole to manhole to bypass sanitary sewer flow during work
• Excavating and removing the existing sewer line and culvert 2 Additionally, although climate change per se was not a specific driver on project design, the larger culvert size is expected to improve conveyance and the addition of stabilizing wingwalls and riprap will reduce the potential for erosion in more intense winter storm events anticipated under future climate scenarios (e.g., Ackerley et al. 2023). 248

• Installing the replacement culvert
• Constructing the headwall and wingwalls at the upstream end of the new culvert • Constructing the headwall at the downstream end of the new culvert • Backfilling around the new culvert and behind the headwall/wingwalls to restore the contours of the channel and roadway embankment; installing the replacement HDPE sanitary sewer line within a concrete encasement above the replaced culvert; placing erosion control as needed on fill slopes • Placing and compacting a 6-inch lift of Class 2 aggregate base on top of the restored embankment fill and conforming the surface to the existing Salson Trail roadway • Constructing the riprap apron at the downstream end of the new culvert • Installing “debris catcher” poles at the upstream end of the culvert Environmental Commitments
Based the results of the Biological Resources Evaluation conducted for the project (Vollmar Natural Lands Consulting 2024), the following Avoidance and Minimization Measures (AMMs) will be incorporated into the project to protect special-status species and sensitive habitats. • Prior to the start of training, the City will retain a qualified biologist to conduct a mandatory biological resources awareness training for all construction personnel. The training will cover - sensitive habitats on the site
- listed and other special-status species that may occur on the site, including their habitats, how to recognize them in the field, the conservation measures that will be required for the project (including the measures below and any additional permit conditions) and the penalities for noncompliance with these measures, and proper procedures in the event a special-status species is observed during construction
Proof of personnel attendance will be kept on file by the City. Translation/interpretation will be provided for non-English-speaking workers. When new construction personnel are added to the project, the City will ensure that the new personnel receive the training before starting work; subsequent training of personnel can include videotape of the initial training and/ or the use of written materials rather than inperson training by a biologist. • Staging and materials laydown will be confined to the existing Salson Trail roadway; no staging will occur within the riparian corridor
• The work and access footprints will be kept to the minimum necessary to accomplish the work; no unnecessary entrance into or disturbance of the riparian corridor or Creek channel will be permitted.

The limits of the work area and access will be delineated in the field prior to contractor mobilization, using temporary construction fencing or another suitable low-impact/high-visibility medium. Fencing or other delineation will be installed under qualified biologist oversight. No entry into the riparian corridor outside the work/access area boundary will be permitted • Construction will be limited to times when East Laurel Creek is not flowing 250

5 • If feasible, work will be conducted outside the nesting season (February 1 – August 31). If work cannot be conducted between September 1 and January 31, the City will retain a qualified biologist to conduct a pre-construction nesting bird survey no more than 1 week prior to the first project-related activity onsite. Any active nests will be protected with no-activity buffers; no entry into the buffer areas will be permitted until the biologist determines that the young have successfully fledged or that the nest has been abandoned. Buffers will be delineated with temporary construction fencing installed under biologist supervision, and buffer widths will be consistent with current California Department of Fish and Wildlife (CDFW) recommendations based on the species of the nesting pair. If state- and/or federally listed species are involved, the City (via the biologist) will coordinate with CDFW and/or the U.S. Fish and Wildlife Service (USFWS) and will proceed in accordance with agency guidance • Pre-construction surveys for pallid bat (Antrozous pallidus) and San Francisco dusky-footed woodrat (Neotoma fuscipes annectens) will be conducted by a qualified biologist within 2 weeks prior to the start of any vegetation- or ground-disturbing activity in the project area. Surveys will be consistent with current CDFW guidance; if either species is observed within the project area, follow-up actions will also be consistent with current CDFW guidance
• If requested by CDFW, pre-construction surveys for western leatherwood (Dirca occidentalis) and California red-legged frog (Rana draytonii) will also be conducted, with appropriate follow-up if either of these species is found to be present. If western leatherwood is observed, the biologist will promptly notify the City and contact CDFW for guidance. If California red-legged frogs at any life stage (eggs, tadpoles, juveniles, or adults) are found, the biologist shall promptly notify the City, and shall contact USFWS and CDFW for guidance.
• No removal or significant disturbance to any trees protected by City Ordinance #2017-1120 will occur unless appropriately authorized by the City. All tree removals will be compensated at a minimum 3:1 ratio under the project Habitat Mitigation & Monitoring Plan (Redtail Consulting 2024) (separately attached)
• Prior to the start of work, water quality best management practices (BMPs) will be put in place to minimize erosion, sediment mobility, and potential impacts to water quality. These may include silt fencing, wattles, fiber mats, and other suitable measures. If wattles are used, they will consist of certified sterile weed-free straw. No monofilament materials will be permitted • Project proponent will implement standard Sudden Oak Death (SOD) and other Phytophthora spp. avoidance and minimization measures, including disinfecting boots and equipment, and only planting Phytophthora-free plants.

Environmental Review & Clearances
As the lead agency for California Environmental Quality Act (CEQA) compliance, the City has determined that the project qualifies for statutory exemption from CEQA review per Section 15269 of the CEQA Guidelines (Emergency Projects). More specifically, the project qualifies as “[e]mergency repairs to publicly…owned service facilities necessary to maintain service essential to the public health, safety or welfare” (Guidelines 15269[b]). A Notice of Exemption will be filed with the State Clearinghouse on project approval, per CEQA Guidelines Section 15062.

As the lead agency for National Environmental Policy Act (NEPA) compliance, the Federal Emergency Management Agency (FEMA)—which is providing grant funding for the project—has determined that the project 251
Salson Trail & Culvert City of Belmont
Project Description November 2024

Environment & Community
qualifies for categorical exclusion from NEPA review in accordance with FEMA Instruction 108-1-1 and FEMA Directive 108-1-1 as authorized by DHS Instruction Manual 023-01-001-01, Revision 1., Categorical Exclusion N9 (Federal Assistance for Flood Hazard Reduction Actions) (Federal Emergency Management Agency 2024a).

FEMA has also concluded that no consultation is warranted under the federal Endangered Species Act or the Magnuson-Stevens Fishery Conservation and Management Act, and that no further action is required for compliance with Section 106 of the National Historic Preservation Act (Federal Emergency Management Agency 2024a, 2024b).

The U.S. Army of Engineers has further indicated that this reach of the Creek is considered an ephemeral stream and thus is not considered a Water of the United States (Galacatos pers. comm.). As result, the project will not require authorization from the U.S. Army Corps of Engineers under Clean Water Act Section 404.

However, the Creek is a Water of the State and displays bed and bank geomorphology, and thus will need to obtain Waste Discharge Requirements per California’s Porter-Cologne Water Quality Control Act as well as a Streambed Alteration Agreement with the California Department of Fish and Wildlife, per Fish and Game Code Section 1602.

STATE WATER RESOURCES CONTROL BOARD
WATER QUALITY ORDER NO. 2004-0004-DWQ

STATEWIDE GENERAL WASTE DISCHARGE REQUIREMENTS

FOR DREDGED OR FILL DISCHARGES TO WATERS DEEMED BY THE
U.S. ARMY CORPS OF ENGINEERS TO BE OUTSIDE OF
FEDERAL JURISDICTION (GENERAL WDRs)
I. FINDINGS
The State Water Resources Control Board (SWRCB) finds that:

Reasons for issuing these General WDRs

1. Section 13260(a) of the California Water Code (Water Code) requires that any person discharging waste or proposing to discharge waste within any region, other than to a community sewer system, which could affect the quality of the waters of the State1, file a report of waste discharge (ROWD). The discharge of dredged or fill material may constitute a discharge of waste that could affect the quality of waters of the State.

2. California has largely relied upon its authority under section 401 of the federal Clean Water Act (CWA) (33 U.S.C. § 1341) to regulate discharges of dredged or fill material to California waters. That section requires an applicant to obtain “water quality certification” from California that the project will comply with State water quality standards before certain federal licenses or permits may be issued. The permits subject to section 401 include permits for the discharge of dredged or fill materials (CWA section 404 permits) issued by the U.S.

Army Corps of Engineers (ACOE).

3. Given the regulatory process employed under section 401, waste discharge requirements under the Porter-Cologne Water Quality Control Act were typically waived for projects that required certification. Regional Water Quality Control Board (RWQCB) waivers also applied to discharges outside of ACOE jurisdiction. However, these waivers expired as of January 1, 2003 pursuant to the requirements of SB 390. These General WDRs regulate some of the activities for which WDRs were previously waived.

4. The certification process under section 401 only applies to those waters that are subject to the reach of the CWA. The CWA applies to “navigable waters,” which are defined in the CWA as “waters of the United States.” The term “waters of the United States” is defined expansively in 33 Code of Federal Regulations (CFR), part 328. In 2001, the U.S. Supreme Court issued a decision in Solid Waste Agency of Northern Cook County v. U.S. Army Corps of Engineers, 531 U.S. 159 (2001) (“SWANCC”), which held that certain “isolated” waters are not subject to CWA jurisdiction merely because they are frequented by migratory birds that cross state lines.

The full implications of SWANCC are yet to be determined in the federal courts, but as a result 1 “Waters of the State” as defined in Water Code section 13050(e).

APPENDIX 2
254

of the decision, many projects that previously would have required a section 404 permit now no longer need one. From January 1, 2001 to December 31, 2003, the ACOE disclaimed jurisdiction over 160 water bodies comprising 449 acres of waters of the state, including 251 acres of wetlands, 121 acres of riparian area, and 77 acres of other waters (these figures are under-reported because 24 percent of the jurisdictional disclaimers did not specify the sizes of the disclaimed waterbodies). The prospect of issuing waste discharge requirements for each of the now non-federal waters, especially in a time of budgetary contraction, is daunting. Many of the projects that were traditionally subject to certification requirements involved small discharges with few or no permanent impacts. It is the intent of these General WDRs to regulate a subset of the discharges that have been determined not to fall within federal jurisdiction, particularly those projects involving impacts to small acreage or linear feet and those involving a small volume of dredged material.

5. Wetlands, riparian areas, and headwaters are shallow waters of the state, which are by their nature affected most often and severely by filling and excavation. Regulatory attention to these water bodies is necessitated by the State "No Net Loss" Policy for wetlands (Executive Order W-59-93); the high habitat value of these waters; the basin-wide value of these waters for pollutant removal, floodwater retention, channel stability, and habitat connectivity; the high number of special-status species associated with these waters and their associated habitats; the high percentage of historic losses of these waters in California; the vulnerability of these waters to future impacts from projected population growth and land development; and the high level of public interest in these waters.

6. Water Code section 13263(a) requires that waste discharge requirements (WDRs) be prescribed as to the nature of any proposed discharge, existing discharge, or material change in an existing discharge. Such WDRs must implement any relevant water quality control plans, taking into consideration beneficial uses to be protected, the water quality objectives reasonably required for those purposes, other waste discharges, the need to prevent nuisance, and the provisions of section 13241 of the Water Code.

7. Water Code section 13263(i) authorizes the SWRCB to prescribe general WDRs for a category of discharges if the discharges are produced by the same or similar operations; the discharges involve the same or similar types of waste; the discharges require the same or similar treatment standards; and the discharges are more appropriately regulated under general discharge requirements than individual discharge requirements.

8. The discharges authorized by these General WDRs meet the criteria for general WDRs set forth in Water Code section 13263(i) because they are all produced by dredging or filling operations; they all involve the discharge of earth, rock, or similar solid materials; they are all limited in size per the terms of the WDRs; they all require similar mitigation techniques to avoid, minimize, and/or compensate for their adverse impacts; and they are all relatively small surface water bodies or water body segments that have been deemed by ACOE to be “isolated,” do not meet the federal wetland criteria, or are above the “line of ordinary high water” limit of federal jurisdiction. They are appropriately regulated under General WDRs because of their similar nature, large numbers, and amenability to being regulated through the use of similar discharge restrictions, as specified in these General WDRs. Regulation of 255
-3-
such discharges by these General WDRs will allow the SWRCB and RWQCBs to direct limited staff time to larger, more complex, and potentially more damaging discharges to waters deemed to be outside of federal jurisdiction.

Eligibility Criteria

9. These General WDRs are restricted to dredged or fill discharges of not more than two-tenths (0.2) of an acre and 400 linear feet for fill and excavation discharges, and of not more than 50 cubic yards for dredging discharges. Projects that may be covered under these General WDRs include land development, detention basins, disposal of dredged material, bank stabilization, revetment, channelization, and other similar projects. These size maximums help limit the potential environmental impact of the discharges and make them amenable to similar discharge restrictions, while permitting about half of the projects discharging to non-federal waters, as projected from historical data on discharge sizes. The size and volume restrictions are appropriate because larger projects involve a significantly greater risk to the environment and are more appropriately regulated by individual WDRs.

Absent a potential effect on the quality of waters of the state, no notification is required under these General WDRs.2
The “quality of waters” refers to chemical, physical, biological, bacteriological, radiological, and other properties and characteristics of water which affects its use.3
Because of the variability, complexity, and interactions of the factors affecting the quality of waters, it is not possible to provide advice on the kind, size, location, or duration of discharges that can affect water quality under all circumstances. Generally, discharges of dredged, fill, or excavated material to a wetland, or to the active channel or bed of a waterbody will require regulation. Discharges to a riparian area or to an area in proximity to a waterbody can affect the quality of the water if they directly or indirectly result in a discharge to the water (e.g., via stormwater flows, during flood events, or by generating pollutants or increased runoff); are associated with a change in the nature of vegetation that could affect water quality (e.g., by affecting pollutant removal, stream shading, or bank stability); or change the hydrologic or geomorphologic characteristics of the waterbody during some flow condition.

These General WDRs do not set a lower size limit below which a Notice of Intent is not required. Neither the Porter-Cologne Water Quality Control Act nor the federal CWA establish a lower size threshold for permitting. If a lower threshold were established in these General WDRs, discharges below that threshold would be subject to regulation under individual WDRs or an individual waiver of WDRs, thus defeating the purpose of these General WDRs.

Moreover, size is not the sole factor dictating the value of a wetland or other water. Small, strategically placed waters, or segments of waters, can play important roles in supporting local habitat, habitat connectivity, pollutant removal, floodwater attenuation, and other beneficial uses. In addition, without a reporting requirement, there would be no way for the State to ensure that multiple small discharges will not have significant cumulative effects.

10. Discharges of fill can directly or indirectly destabilize the channel or bed of a receiving water by changing geomorphic parameters, including hydrologic characteristics, sediment characteristics, or stream grade. Such destabilization diminishes the ability of the water body

2 Water Code section 13260
3 Water Code section 13050(g)
256
-4-
to support designated beneficial uses. Quantification and mitigation of such impacts may require detailed project-specific analyses. Therefore, these General WDRs do not authorize discharges that could destabilize the channel or bed of a receiving water.

11. In urbanizing basins or other situations, a large number of relatively small projects potentially eligible for these General WDRs, in their aggregate, may adversely impair the ability of the water body to support beneficial uses. Quantification and mitigation of such impacts may require basin-wide analyses. Therefore, these General WDRs do not authorize discharges that, when considered in conjunction with other potential discharges, could cause a significant cumulative effect on water quality or beneficial uses.

12. To the extent they are determined to fall within federal jurisdiction, it is likely that the SWRCB and RWQCBs will continue to regulate dredged or fill discharges primarily through their authority under section 401 of the CWA. Therefore, these General WDRs do not apply to discharges to federal waters that are subject to sections 401 and 404 of the CWA. These General WDRs likewise do not apply to discharges regulated under a section 402 storm water permit.

13. Discharges which could have a significant impact on rare, candidate, threatened, or endangered species require detailed project-specific analysis and individual regulation. Such discharges are therefore not authorized by these General WDRs.

14. Although a discharge may be eligible for coverage under these General WDRs, the RWQCB may elect to regulate the discharge under other WDRs or waivers thereof.

15. Discharges that would be exempt pursuant to section 404(f) of the CWA are waived from these WDRs. This waiver shall not affect a RWQCB’s authority to issue individual WDRs or waivers for such discharges if it deems it appropriate.

Mitigation Plan

16. SWRCB Resolution No. 68-16, “Statement Of Policy With Respect To Maintaining High Quality Of Waters In California” (“Antidegradation Policy”), states that discharges to existing high quality waters will be required to meet WDRs which will result in the best practicable treatment or control of the discharge necessary to assure that (a) a pollution or nuisance will not occur, and (b) the highest water quality consistent with maximum benefit to the people of the State will be maintained.

17. Executive Order W-59-93, dated August 23, 1993, establishes a California Wetlands Conservation Policy including an objective to ensure no overall net loss of and a long term net gain in the quantity, quality, and permanence of wetland acreage and value in California (“No Net Loss Policy”).

18. Filling wetlands, riparian areas, headwaters, and other waters causes partial or complete loss of the beneficial uses provided by those waters. To reconcile such losses with the “No Net 257
-5-
Loss” requirements of Executive Order W-59-93 and the “Antidegradation” requirements of SWRCB Resolution No. 68-16, these General WDRs require mitigation plans to ensure that impacts are mitigated through avoidance and minimization and that unavoidable loss of beneficial uses is offset with appropriate compensatory mitigation, including creation, restoration, or (in exceptional cases) preservation of other waters of the state. These mitigation requirements are consistent with those adopted by the U.S. Environmental Protection Agency and the ACOE for regulation of dredged or fill discharges to federal waters under CWA section 404.

19. To comply with the objective of the State “No Net Loss Policy” to ensure the quantity, quality, and permanence of wetland acreage and values in California, and with the “Antidegradation” requirements of SWRCB Resolution No. 68-16, these General WDRs require that compensatory mitigation areas for permanent impacts be subject to a deed restriction or other legal instrument that ensures preservation of the mitigation in perpetuity.

These General WDRs do not generally require compensatory mitigation for temporary impacts, because the SWRCB does not anticipate that projects eligible under this order would ordinarily create temporary impacts of a size, severity, and/or duration that would have a significant adverse impact on beneficial uses. The decision in this order to generally require compensatory mitigation only for permanent impacts is not meant to be a precedent for any other SWRCB or RWQCB order.

20. Consistent and equitable application of these General WDRs is in the interest of environmental protection and the applicants. These General WDRs therefore provide guidance to SWRCB and RWQCB staffs regarding factors to evaluate in considering the eligibility of these General WDRs and in evaluating mitigation plans.

Basin Plans

21. All WDRs must implement the RWQCB Water Quality Control Plan (Basin Plan) for the region affected by the discharge. These General WDRs require dischargers to comply with all applicable Basin Plan provisions, including maintaining the protection of beneficial uses and complying with any prohibitions and water quality objectives governing the discharge.

Beneficial Uses

22. Beneficial uses are the most fundamental of the State’s water quality standards. RWQCBs designate appropriate beneficial uses for waters in their regions’ Basin Plans. The beneficial uses for the waters of the State include, but are not limited to, domestic supply, municipal supply, agricultural and industrial supply, power generation, recreation, aesthetic enjoyment, navigation, and preservation and enhancement of fish, wildlife, and other aquatic resources or preserves.

Fees

23. Water Code section 13260(d)(1) requires that each person for whom WDRs have been prescribed pursuant to section 13263 shall submit an annual fee according to a reasonable fee 258
-6-
schedule established by the SWRCB. The schedule of fees for discharges of dredged or fill material is published at California Code of Regulations (CCR) 23 section 2200(a)(2). For activities covered by these General WDRs, the SWRCB anticipates that most of the discharges will be one-time and of short duration. Therefore, only a one-time fee usually will be charged.

California Environmental Quality Act (CEQA)

24. CEQA requires a government agency to comply with certain procedures when it approves or proposes to carry out an activity. (Cal. Code Regs., tit. 14, § 15002(e))

25. Private actions are subject to CEQA if they involve governmental participation, financing, or approval. (Cal. Code Regs., tit. 14, § 15002(c))

26. A Mitigated Negative Declaration in compliance with CEQA has been adopted for these General WDRs.

27. Potential dischargers and all other known interested parties have been notified of the intent to adopt these General WDRs.

28. All comments pertaining to the proposed discharges have been heard and considered in a public meeting.

II. ORDER
A. ELIGIBILITY
IT IS HEREBY ORDERED that only discharges that meet the following criteria shall be enrolled under these General WDRs:

1. The discharge shall not be subject to section 404 of the CWA or section 10 of the federal Rivers and Harbors Act. These General WDRs likewise do not apply to discharges regulated under a section 402 storm water permit.

2. The discharge shall be dredged or fill materials.

3. The discharge shall meet the following size criteria:
a. Excavation4
and fill activities must not excavate or fill an area greater than two-tenths (0.2) of an acre of waters of the state, and

4 “Excavation refers to moving sediment or soil in shallow waters or under no-flow conditions where impacts to beneficial uses are best described by the area of discharge. It typically is done for purposes other than navigation. Examples include trenching for utility lines, other earthwork preliminary to construction, removing sediment to increase channel capacity, and aggregate mining in fresh water.” (Cal. Code Regs., tit. 23, § 2200(a)(2).)
259
-7-
b. Linear excavation and fill activities affecting drainage features and shorelines (e.g., bank stabilization, revetment, and channelization projects), must not excavate or fill more than 400 linear feet of waters of the state, measured parallel to the streambank or shoreline, and
c. Dredging5
activities must dredge not more than 50 cubic yards within waters of the state.
d. These size criteria apply to discharges, which could either permanently or temporarily affect the quality of waters of the state6
.
e. These size criteria apply to complete projects and shall not be used to authorize “piecemealing” of larger discharges. In regulating recurring discharges, e.g., routine maintenance of sedimentation basins, forebays, or similar waters, these criteria shall be applied for each discharge episode.

4. For purposes of defining the size criteria specified in this section, determining fees as required by section II.B.3, and evaluating mitigation proposals as required by section II.B.4 of these General WDRs, the lateral extent of waters of the state shall be determined by the most expansive of the following:
a. The federal criteria current on the date of adoption of these General WDRs7 ,
b. Headwaters, defined as intermittent and ephemeral drainages.

5. The discharge shall not directly or indirectly destabilize a channel or bed of a receiving water. In determining whether a discharge meets this criterion, the RWQCB Executive Officer8
will consider potential project-induced changes to:

5 “Dredging” refers to removing sediment in deeper water to increase the depth. Impacts to beneficial uses are best described by the volume of the discharge. It typically occurs to facilitate navigation and for aggregate extraction in marine waters.
6 Fill or dredged discharges can permanently affect the quality of waters of the state when the discharged material will be in place indefinitely and/or by its nature precludes a reasonable assurance that beneficial uses will be fully reestablished. Examples include filling of wetlands or other waters, streambank hardening, channelization, construction of bridge piers and abutments, and ongoing vegetation removal and channel maintenance. Fill or dredged discharges can temporarily affect the quality of waters of the state when the discharged material will be in place for a limited time and/or there is a reasonable assurance that beneficial uses will be fully reestablished once the discharge ceases. Examples include temporary fills, excavation for temporary access roads, and onetime vegetation removal or excavation of sediment. Mitigation measures or management practices may be needed to assure that impacts are “temporary” (e.g., reestablishment of natural grade, revegetation, reestablishment of soil permeability to allow vegetative growth, compaction of backfill to assure that utility trenches do not dewater wetlands).

-8-
a. Quantity, velocity, timing, and direction of flow;
b. Sediment characteristics;
c. Stream grade; and
d. Other relevant project-induced changes.

6. The discharge shall not cause in combination with other discharges a significant cumulative effect on water quality or beneficial uses of the waters of the State including, but not limited to, wetlands and headwaters.

7. The discharge shall not adversely impact, either directly or through habitat modification, any plants or animals identified as candidate, sensitive, or special status species in local or regional plans, policies or regulations; or by the California Department of Fish and Game (DFG), the U.S. Fish and Wildlife Service (USFWS), or the National Marine Fisheries Service (NMFS). The project shall not , substantially reduce the habitat of fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, or reduce the number of or restrict the range of an endangered, rare or threatened species.

8. The discharge shall not significantly conflict with any adopted and approved USFWS Habitat Conservation Plan (HCP) or DFG Natural Community Conservation Plan (NCCP).

9. The discharge shall not adversely impact a significant historical or archeological resource, shall not directly or indirectly destroy a unique paleontological resource or site or unique geologic feature, shall not disturb any human remains, and shall not eliminate important examples of the major periods of California history or prehistory.

10. The discharge shall not cause conflict with existing zoning for agricultural use or a Williamson Act contract.

11. The discharge, as mitigated, shall not cause significant adverse environmental impacts.

12. Discharges that would be exempt pursuant to section 404(f) of the CWA are waived from these WDRs. This waiver shall not affect a RWQCB’s authority to issue individual WDRs or waivers for such discharges if it deems it appropriate.

B. APPLICATION REQUIREMENTS
IT IS FURTHER ORDERED that dischargers seeking enrollment under these General WDRs shall submit the following to the appropriate RWQCB Executive Officer or, in the case of multiRegion projects, to the SWRCB Water Quality Certification Program Manager at least 45 days prior to any discharge:

1. A Notice of Intent (NOI) to be enrolled under and to comply with these General WDRs.

2. Any CEQA documents that have been prepared for the project. 261
-9-

3. A fee pursuant to Title 23, section 2200 of the CCR.

4. A Mitigation Plan:

The Mitigation Plan shall demonstrate that the discharger will sequentially avoid, minimize, and compensate for the adverse impacts to the affected water bodies’ beneficial uses (as defined in the applicable Basin Plan). The Mitigation Plan shall address the following:
a. Avoidance: No discharge shall be permitted if there is a practicable alternative9 to the
proposed discharge, which would have less adverse impact to the aquatic ecosystem, as long as the alternative does not have other significant adverse environmental consequences.
b. Minimization: Unavoidable temporary impacts shall be mitigated by restoring water bodies and vegetation to pre-discharge conditions as quickly as practicable and by taking other practicable measures to reduce the severity and duration of such impacts. c. Compensatory mitigation: Discharges resulting in unavoidable permanent impacts to wetlands or headwaters shall ensure “no net loss” of area (acreage), functions, and beneficial use values by providing appropriate compensatory mitigation including creation, restoration, or (in exceptional cases) preservation. The RWQCB Executive Officer/SWRCB Executive Director will consider, at a minimum, the following when reviewing the adequacy of compensatory mitigation:
(1) Onsite habitat value
(2) Habitat connectivity value
(3) Floodwater retention value
(4) Pollutant removal value
(5) Ratio of area of proposed compensation to proposed loss (6) Proposed revegetation and irrigation plans and success criteria (7) Availability of suitable soils, hydrology, and natural vegetation at the compensation site (8) Monitoring and reporting provisions
(9) Contingency plan for failure to achieve success criteria (10) Any other information requested by the RWQCB or SWRCB.

The Mitigation Plan shall demonstrate that all potentially adverse environmental impacts have been mitigated to a less than significant level. The thoroughness of the alternatives analysis and the extent of the proposed mitigation shall be commensurate with the purpose of the discharge, the value and sensitivity of the receiving water(s), and the extent, severity, and duration of the effect on the quality of waters.

9 An alternative is practicable if it is available and capable of being done after taking into consideration cost, existing technology, and logistics in light of overall project purposes. If it is otherwise a practicable alternative, an area not presently owned by the applicant which could reasonably be obtained, utilized, expanded, or managed in order to fulfil the basic purpose of the proposed activity may be considered (this definition is the same as presented in federal regulations at section 230.10(a)(2) of Title 33 of the CFR). 262
-10-

5. Any other additional information requested by the SWRCB or RWQCB to evaluate the proposed dredged or fill discharge.

A discharge shall not be enrolled under these General WDRs unless the RWQCB Executive Officer or SWRCB Executive Director finds that the Mitigation Plan meets the requirements of this section and the discharge meets all other eligibility criteria. The RWQCB Executive Officer or SWRCB Executive Director shall independently determine eligibility, including the adequacy of the Mitigation Plan, but may consider findings and requirements included in other agencies’ permits.

C. DISCHARGE REQUIREMENTS
IT IS FURTHER ORDERED that the discharger shall comply with the following:

Prohibitions:

1. The discharge of material is prohibited until the discharger has received a Notice of Applicability (NOA) from the RWQCB Executive Officer or the SWRCB Executive Director or until 45 days after submission of a complete and accurate NOI.10 If the RWQCB Executive Officer or the SWRCB Executive Director has not issued a Notice of Exclusion (NOE) within 45 days of receiving a complete and accurate NOI, the discharge may proceed.

2. No discharges are authorized under these General WDRs if the discharger has received a NOE from the RWQCB Executive Officer or the SWRCB Executive Director.

3. The discharge shall not cause pollution, contamination, or nuisance as defined in Water Code section 13050.

4. The discharge of material in a manner other than as described in the NOI, the Findings or conditions of these General WDRs, or in the RWQCB Executive Officer or SWRCB Executive Director-approved Mitigation Plan is prohibited.

5. The discharge of substances in concentrations toxic to human, plant, animal, or aquatic life or that produce detrimental physiological responses therein, is prohibited.

6. The discharge of waste classified as “hazardous” or “designated” as defined in Title 22, section 66261 of the CCR, or Water Code section 13173 is prohibited.

Special Provisions:

7. The discharger shall discharge in a manner that is consistent with the information provided in the NOI.

10 The RWQCB Executive Officer or the SWRCB Executive Director, within 30 days from submittal of the NOI, may find a submittal to be incomplete or inaccurate.
263
-11-

8. The discharger shall comply with the eligibility criteria for these General WDRs.

9. The discharger shall implement the approved Mitigation Plan.

10. Requested amendments to the approved Mitigation Plan must be submitted in writing to the RWQCB Executive Officer and, for multi-region projects, to the SWRCB Water Quality Certification Program Manager. The discharger may not modify operations until the discharger has received written notification that the RWQCB Executive Officer or SWRCB Executive Director has approved the amendment. If the RWQCB Executive Officer or the SWRCB Executive Director does not disapprove the requested amendment within 45 days of receiving the written notification, the changes to the approved Mitigation Plan may be implemented as described in the requested amendment.

11. If mitigation measures do not meet their interim or ultimate success criteria, the discharger shall implement remedial measures that are acceptable to the RWQCB Executive Officer or SWRCB Executive Director.

12. All compensatory mitigation areas shall be subject to a conservation easement, deed restriction, or other legal instrument, which shall ensure preservation of the mitigation in perpetuity.

Documentation of the easement, restriction, or other legal instrument shall be submitted to the RWQCB, or to the SWRCB for multi-region projects, before any discharge authorized by these General WDRs occurs.

13. The discharger, if requested by the RWQCB or SWRCB, shall provide certification that supervisory and other responsible operations personnel have received training regarding these General WDRs.

14. Fueling, lubrication, maintenance, operation, and storage of vehicles and equipment shall not result in a discharge or a threatened discharge to water bodies. At no time shall the discharger use vehicles or equipment that leak any substance that might impact water quality.

Staging and storage areas for vehicles and equipment shall be located outside of water bodies.

15. Except in compliance with the terms of an NOA for this order, no construction material, spoils, debris, or other substances associated with this project, that may adversely impact water quality, shall be located in a manner which may result in a discharge or threatened discharge to water bodies.

16. Upon completion of the project, the discharger shall complete a Notice of Termination (NOT) requesting to be un-enrolled from these General WDRs.

Standard Provisions:

17. A copy of these General WDRs shall be kept at the project site for reference by project personnel. Personnel shall be familiar with its contents. 264
-12-

18. The discharger shall take all reasonable steps to prevent any discharge in violation of these General WDRs.

19. The discharger shall report promptly to the RWQCB or SWRCB any proposed material change in the character, location, area, and/or volume of the discharge. The discharger shall obtain confirmation from the RWQCB or SWRCB that such proposed modifications do not disqualify the discharger from coverage under these General WDRs. Confirmation or new WDRs shall be obtained before any modifications are implemented. If the RWQCB Executive Officer or the SWRCB Executive Director does not disapprove the proposed change within 45 days of receiving a written report describing the proposed change, the discharge may proceed in accordance with the proposed modifications.

20. These General WDRs do not convey any property rights or exclusive privileges. The requirements prescribed herein do not authorize the commission of any act causing injury to persons or property, do not protect the discharger from liability under federal, State, or local laws, and do not create a vested right to continue to discharge waste.

21. These General WDRs do not relieve the discharger from the responsibility to obtain other necessary local, State, and federal permits, nor do these General WDRs prevent imposition of additional standards, requirements, or conditions by any other regulatory agency.

22. The discharger shall allow the RWQCB or SWRCB, or an authorized representative, upon the presentation of credentials and other documents, as may be required by law, to do the following:
a. Enter upon the premises where a regulated facility or activity is located or conducted, or where records must be kept under the conditions of these General WDRs, b. Have access to and copy, at reasonable times, any records that must be kept under the conditions of these General WDRs,
c. Inspect at reasonable times any facilities, equipment (including monitoring and control equipment), practices, or operations regulated or required under these General WDRs, and
d. Sample, photograph, and monitor at reasonable times, for the purpose of assuring compliance with these General WDRs.

23. After notice and opportunity for a hearing, coverage of an individual discharge under these General WDRs may be terminated or modified for cause, including, but not limited to, the following:
a. Violation of any term or condition of these General WDRs. b. Obtaining these General WDRs by misrepresentation or failure to disclose all relevant facts.
265
-13-
c. A change in any condition that requires either a temporary or permanent reduction or elimination of the authorized discharge.

24. The filing of a request by the discharger for an order modification, revocation and reissuance, or termination, or a notification of planned changes or anticipated noncompliance does not stay any condition of these General WDRs.

25. Where the discharger becomes aware that it failed to submit any relevant facts in an NOI or submitted incorrect information in an NOI to the RWQCB or SWRCB, it shall promptly submit such facts or information.

26. The discharger shall furnish, within a reasonable time, any information the RWQCB or SWRCB may request to determine whether cause exists for modifying, revoking and reissuing, or terminating the discharger coverage under these General WDRs. The discharger shall also furnish to the RWQCB or SWRCB, upon request, copies of records required to be kept by these General WDRs.

27. The Water Code provides that any person failing or refusing to furnish technical or monitoring program reports, as required under these General WDRs, or falsifying any information provided in the monitoring reports, is subject to civil liability for each day in which the violation occurs.

28. The discharger shall take all reasonable steps to minimize or correct any adverse impact on the environment resulting from noncompliance with these General WDRs, including such accelerated or additional monitoring as may be necessary to determine the nature and impact of the noncompliance.

29. All reports, notices, or other documents required by these General WDRs or requested by the RWQCB or SWRCB shall be signed by a person described below or by a duly authorized representative of that person.
a. For a corporation: by a responsible corporate officer such as (1) a president, secretary, treasurer, or vice president of the corporation in charge of a principal business function; (2) any other person who performs similar policy or decision-making functions for the corporation; or (3) the manager of one or more manufacturing, production, or operating facilities if authority to sign documents has been assigned or delegated to the manager in accordance with corporate procedures.
b. For a partnership or sole proprietorship: by a general partner or the proprietor. c. For a municipality, State, federal, or other public agency: by either a principal executive officer or ranking elected official.

30. Any person signing a document under Provision II.C.29 shall make the following certification, whether written or implied:
266
-14-
“I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gathered and evaluated the information submitted. Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief, true, accurate, and complete. I am aware there are significant penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations.”

31. The discharger shall report any discharge of waste that may endanger public health or the environment. Any information shall be provided orally to the RWQCB within 24 hours from the time the discharger becomes aware of the occurrence. A written report shall also be submitted to the RWQCB Executive Officer within five (5) consecutive days of the time the discharger becomes aware of the occurrence. The written report shall contain (a) a description of the noncompliance and its cause; (b) the period of the noncompliance event, including dates and times, and if the noncompliance has not been corrected, the anticipated time it is expected to continue; and (c) steps taken or planned to reduce, eliminate, and prevent reoccurrence of the noncompliance.

32. The discharger shall report all instances of noncompliance not reported under Provision II.C.31 within seven (7) consecutive days of the time the discharger becomes aware of the occurrence.

The report shall contain any applicable information listed in Provision II.C.31.
