Failure of the City to object to a proposed I-B-7 Agreement No. 7526 Subcontractor before award will not preclude the City from requiring replacement of any Subcontractor based upon information received subsequent to award, information which cannot be properly evaluated before award due to time constraints, or information relating to a failure to comply with the requirements of the Contract. 14.7If Bidder submits the original signed Agreements and all other items within ten (10) days after receiving the City’s notification, and all such items comply with the requirements of the Bidding Documents, the City will award the Contract to Bidder by signing the Agreement and returning a signed copy of the Agreement to Bidder. 14.8 If the City consents to the withdrawal of the Bid of the apparent lowest responsible Bidder, or the apparent lowest responsible Bidder fails or refuses to sign the Agreement or submit to the City all of the items required by the Bidding Documents, within ten (10) days after receiving the City’s notification, or the City determines that the Bidder is not financially or otherwise qualified to perform the Contract, the City may reject such Bidder’s Bid and select the next apparent lowest responsible Bidder, until all bids are exhausted, or reject all Bids.

Only one subcontractor will be listed for each portion of the work, which portion will be defined in the bid. In each instance, the nature and extent of the work to be sublet will be described. The failure of the Contractor to specify a subcontractor, or the listing of more than one subcontractor for the same portion of the work, constitutes an agreement by the Contractor that it is fully qualified to perform that portion itself and that it will perform that portion itself. The Contractor must have the City Council’s written consent to substitute a subcontractor other than that designated in the original bid, to permit any subcontract to be assigned or transferred, or to allow a subcontract to be performed by other than the original subcontractor. Subcontracting of work for which no subcontractor was designated in the original bid, and which is more than one-half of one percent of the work, will be allowed only in cases of public emergency or necessity, and then only after a finding reduced to writing as a public record of the City Council setting forth the facts constituting the emergency or necessity. Violation of any of the above provisions will be considered a breach of the Contract, and the City may terminate the Contractor’s control over the Work, cancel the contract, or assess the Contractor a penalty of not more than ten percent of the subcontract involved. All persons engaged in the work, including subcontractors and their employees will be considered as employees of the Contractor. The Contractor will be solely responsible for and have control over construction means, methods, techniques, sequences, procedures, and the coordination of all portions of the Work. The City will deal directly with, and make all payments to, the prime Contractor. When subcontracted work is not being prosecuted in a satisfactory manner, the Contractor will be notified to take corrective action. The Engineer may report the facts to the City Council. If the City Council so orders, and on receipt by the Contractor of written instructions from the Engineer, the subcontractor will be removed immediately from the Work. The subcontractor will not again be employed on the Work. If licensure or proper licensure is controverted, then proof of licensure pursuant to this section must be made by production of a verified certificate of licensure from the Contractors’ State License Board which establishes that the individual or entity bringing the action was duly licensed in the propert classification of contractors at all times during the performance of any act or contract covered by the action. Nothing in II-B-3 Agreement No. 7526 this subdivision requires any person or entity controverting licensure or proper licensure to produce a verified certificate. When licensure or proper licensure is controverted, the burden of proof to establish licensure or proper licensure is on the licensee. 1-6.3 Additional Responsibility Add the following Subsection 1-6.3 Additional Responsibility: The Contractor will submit experience statements for each subcontractor who will perform contract work that amounts to more than ten percent (10%) of the Work. 1-7 AWARD AND EXECUTION OF THE CONTRACT 1-7.2 Contract Bonds Delete Paragraph four (4) of the Subsection and insert: The “Performance Bond” shall be for 100% of the Contract Price to guaranty faithful performance of all work, within the time prescribed, in a manner satisfactory to the City, and that all materials and workmanship will be free from original or developed defects.

All work requiring that a lane be closed or a lane moved right or left will be noticed to the traveling public by use of City approved lighted arrow boards. Clearances from traffic lanes will be five (5) feet to the edge of any excavation and two (2) feet to the face of any curb, pole, barricade, delineator, or other vertical obstruction. One four (4) foot wide paved pedestrian walkway will be maintained in the parkway area on each side of all streets. The clearance from the pedestrian walkway to any traffic lane will be five (5) feet. Pedestrians and vehicles will be protected from all excavations, material storage, and/or obstructions by the placement of an adequate number of lighted barricades (minimum two (2)) at each location, one (1) at each end of the obstruction or excavation), which will have flashing lights during darkness. Barricades will be Type I or Type II per Section 7-3 of the WATCH manual and lights will be Type A per Section 7-6 of the “Work Area Traffic Control Handbook” (WATCH). 3-12.8.2 Street Closures, Detours, and Barricades Street closures will not be allowed except as specifically permitted by the Engineer. The Contractor will prepare any traffic control or detour plans that may be required as directed by the Engineer. Lane transitions will not be sharper than a taper of thirty (30) to one (1). Temporary traffic channelization will be accomplished with barricades or delineators. Temporary striping will not be allowed unless specifically permitted by the Engineer.

Plates subject to vehicle high traffic speeds and in residential areas will be secured by welding at the discretion of the Engineer. 3-12.8.3 Protection of the Public It is part of the service required of the Contractor to make whatever provisions are necessary to protect the public. The Contractor will use foresight and will take such steps and precautions as his operations warrant to protect the public from danger, loss of life or loss of property, which would result from interruption or contamination of public water supply, interruption of other public service, or from the failure of partly completed work or partially removed facilities. Unusual conditions may arise on the Project which will require that immediate and unusual provisions be made to protect the public from danger or loss of life, or damage to life and property, due directly or indirectly to prosecution of work under this contract. Whenever, in the opinion of the Engineer, an emergency exists against which the Contractor has not taken sufficient precaution for the public safety, protection of utilities and protection of adjacent structures or property, which may be damaged by the Contractor’s operations and when, in the opinion of the Engineer, immediate action will be considered necessary in order to protect the public or property due to the Contractor’s operations under this contract, the Engineer will order the Contractor to provide a remedy for the unsafe condition. If the Contractor fails to act on the situation immediately, the Engineer may provide suitable protection to said interests by causing such work to be done and material to be furnished as, in the opinion of the Engineer, may seem reasonable and necessary. The cost and expense of said labor and material, together with the cost and expense of such repairs as are deemed necessary, will be borne by the Contractor. All expenses incurred by the City for emergency repairs will be deducted from the progress payments and the final payment due to the Contractor. Such remedial measures by the Citywill not relieve the Contractor from full responsibility for public safety. 3-13 COMPLETION AND ACCEPTANCE Delete Subsection 3-13 of the Greenbook in its entirety and replaced with the following: The Work will be inspected by the Engineer for acceptance upon the Engineer receiving the Contractor’s written assertion that the Work is complete.

After receiving notice from the Contractor, the Engineer will promptly investigate any condition identified by the Contractor as being hazardous. The rights and obligations of the City and the Contractor with regard to such conditions (including, without limitation, the procedures for procuring change orders and filing claims) will be specified by the provisions of Subsection 2-9 (Changed Conditions) of the Greenbook. If a dispute arises between the City and the Contractor whether the conditions materially differ, involve hazardous waste, or cause a change in the Contractor's cost or time required for performance of the work, the Contractor will not be excused from II-B-20 Agreement No. 7526 any scheduled completion date provided for by the contract, but will proceed with all work to be performed under the contract. The Contractor will retain all rights provided by Subsection 2-10, Disputed Work, of the Greenbook. If the Engineer determines that material called to the Engineer's attention by the Contractor is hazardous waste, or if the Engineer otherwise discovers the existence of hazardous waste, the Contractor will be responsible for removal and disposal of the hazardous waste by qualified personnel and appropriate equipment in the manner required by law as directed by the Engineer, subject to the provisions of Section 2 (Scope ofWork) of the Greenbook. SECTION 6 – PROSECUTION AND PROGRESS OF THE WORK 6-1 CONSTRUCTION SCHEDULE AND COMMENCEMENT OF WORK Delete Section 6-1, and replace with the following: Pre-Construction Meeting: After contract award, the City will arrange for a pre-construction meeting to discuss the construction of the project. City will invite utility agenciesand the contractor will arrange for all of its sub-contractors to attend the meeting. 6-1.1 Contract Schedule After notification of award and before starting any work, the Contractor will submit a Contract Schedule to the Engineer for review, as required by these Specifications within fifteen (15) calendar days of award. 6-1.2 Content of the Contract Schedule The Contract Schedule, and any updated Contract Schedule, will meet the following requirements: 1. Schedules must be suitable for monitoring progress of the Work. 2. Schedules must provide necessary data about the time for the Engineer’s decisions. 3. Schedules must be sufficiently detailed to demonstrate adequate planning for the Work. 4. Schedules must represent a practical plan to complete the Work within the Contract Time. 5. Schedules must show the critical path method for completing the Work. II-B-21 Agreement No. 7526 The Engineer’s review of the form and general content of the Contract Schedule and any updated Contract Schedules is only for the purpose of determining if the listed requirements are satisfied, nothing more. 6-1.3 Effect of Contract Schedule The Contract Schedule, and any Contract Schedule updates, will represent a practical plan to complete the Work within the Contract Time. Extension of any schedule beyond the Contract Time will not be acceptable. Schedules showing the Work completed in less than the Contract may be acceptable if judged by the Engineer to be practical. Acceptance of such a schedule by the Engineer will not change the Contract Time. The Contract Time, not the Contract Schedule, will control in determining liquidated damages payable by the Contractor and in determining any delay. If a schedule showing the Work completed in less than the Contract Time is accepted, the Contractor will not be entitled to extensions of the Contract Time for Excusable Delays or Compensable Delays or to adjustments of the Contract Sum for Compensable Delays until such delays extend the completion of the Work beyond the expiration of the Contract Time. The Contractor will plan, develop, supervise, control, and coordinate the performance of the Work so that its progress and the sequence and timing of Work activities conform to the current accepted Contract Schedule. The Contractor will continuously obtain from Subcontractors information and data about the planning for and progress of the Work and the delivery of equipment, will coordinate and integrate such information and data into updated Contract Schedules, and will monitor the progress of the Work and the delivery of equipment. The Contractor will act as the expeditor of potential and actual delays, interruptions, hindrances, or disruptions for its own forces and those forces of Subcontractors. The Contractor will cooperate with the Engineer in developing the Contract Schedule and updated Contract Schedules. The Engineer’s review and comments about any schedule or scheduling data will not relieve the Contractor from its sole responsibility to plan for, perform, and complete the Work within the Contract Time. Review and comments about any schedule will not transfer responsibility for any schedule to the Engineer or the City nor imply their agreement with (1) any assumption upon which such schedule is based or (2) any matter underlying or contained in such schedule. The Engineer’s failure to discover errors or omissions in schedules that have been reviewed, or to inform the Contractor that the Contractor, Subcontractors, or others are behind schedule, or to direct or enforce procedures for complying with the Contract Schedule will not relieve the Contractor from its sole responsibility to perform and complete the Work within the Contract Time and will not be a cause for an adjustment of the Contract Time or the Contract Sum. The Contractor will perform the Work in accordance with the currently accepted II-B-22 Agreement No. 7526 Contract Schedule. 6-1.4 Commencement of Contract Time The Contract Time will commence when the City issues a Notice to Proceed. The Work will start on the date specified in the Notice to Proceed and within a maximum of fifteen (15) days after the date of the Notice to Proceed, and be diligently prosecuted to completion with the time provided in the Specifications. 6-3.3 Working Days and Working Hours City Hall is open from Monday thru Thursday 7am -5pm and Friday’s 7am-4pm. It is closed on the following holidays: New Year’s Day Martin Luther King, Jr. Day President’s Day Memorial Day Independence Day Labor Day Veterans’ Day Thanksgiving Christmas Eve Christmas New Year’s Eve Working on Fridays when City Hall is closed is acceptable. If the Contractor, however, requests an inspection a day when City Hall is closed, then the Contractor will have to reimburse the City for the costs of inspection. The Contractor must request such an inspection at least 48 hours in advance. City inspections during hours when City Hall is closed are subject to inspection overtime fees to be paid for by the Contractor. Friday work that does not require inspection can be done without an inspection fee and must be discussed with City staff before its occurrence. If the Contractor does construction on a Friday or a day when City Hall is closed, that day is counted as a project working day. On workdays, Contractor’s activities will be confined to the hours between 7:00 a.m. and 4:00 p.m. Please see Section 6-3.5 below for weekend and holiday work restrictions. 6-3.4 Night Work Add the following paragraph: The City will not permit Work between the hours of 4 p.m. and 7 a.m. of the following day unless specifically provided for in the bid documents or unless the Contractor II-B-23 Agreement No. 7526 receives prior written approval. 6-3.5 Weekend and Holiday Work The Engineer may, but is not required to, allow the Contractor to work on Saturdays, Sundays and City Holidays. 6-4 DELAYS AND EXTENSIONS OF TIME Delete and replaced with the following: 6-4.1 General If delays are caused by unforeseen events beyond the control of the Contractor, such delays will entitle the Contractor to an extension of time as provided herein, but the Contractor will not be entitled to damages or additional payment due to such delays except as otherwise provided herein. Excusable delay may include: war, earthquakes exceeding 3.5 on the Richter Scale, government regulation, labor disputes outside the contemplation of the parties, strikes outside the contemplation of the parties, fires, floods, changes to the Work as identified herein, or other specific events that may be further described in the Specifications. Delays to the Project caused by labor disputes or strikes involving trades not directly related to the Project, or involving trades not affecting the Project as a whole will not warrant an extension of time. The City will not grant an extension of time for a delay by the Contractor’s inability to obtain materials unless the Contractor furnishes to the Engineer documentary proof. The proof must be provided in a timely manner in accordance with the sequence of the Contractor’s operations and accepted construction schedule. Should delays be caused by events other than those included herein, the Engineer may, but is not required to, deem an extension of time to be in the City’s best interests. 6-4.2 Extensions of Time If granted, extensions of time will be based upon the effect of delays to the critical path of the Work as determined by the current accepted Contract Schedule. Delays to minor portions of the Work that do not affect the critical path will not be eligible for extensions of time. 6-4.3 Payment for Delays to Contractor Any payment for compensable delay will be based upon actual costs as set forth in Subsection 402-5.1 excluding, without limitation, what damages, if any, the Contractor may have reasonably avoided. The Contractor understands that this is the sole basis for II-B-24 Agreement No. 7526 recovering delay damages and explicitly waives any right to calculate daily damages for office overhead, profit, or other purported loss, using different formulas including, without limitation, the Eichleay Formula. 6-6.4 Written Notice and Report If the Contractor desires payment for a delay or an extension of time, it will give the Engineer written notice of such request not later than the time limit set forth in the Proposal for submitting a claim after the event or occurrence giving rise to a delay claim. Failure to submit a written request within such amount of time will result in the Contractor waiving its delay claim. Any claim for payment or an extension of time must be in the form required by the “Claims” sections of these Specifications. In no event will the City grant the Contractor an extension of time if the delay is within the Contract Time as identified by the Contract Documents. 6-7 DEFAULT BY CONTRACTOR The language in subsection 6-7 is deleted in its entirety and replaced with the following subsections. 6-7.1 General Should the Contractor fail to begin delivery of material and equipment, to commence the Work within the time specified, to maintain the rate of delivery of material, to execute the Work in the manner and at such locations as specified, or fail to maintain the Work schedule (as determined by the current accepted Contract Schedule) which will ensure the City’s interest, or if the Contractor is not carrying out the intent of the Contract, the City may serve written notice upon the Contractor and the Surety on its Faithful Performance Bond demanding satisfactory compliance with the Contract. 6-7.2 Termination of Contractor’s Control Over the Work The City may terminate the Contractor’s control over the Work without liability for damages when, in the City’s opinion, the Contractor is not complying in good faith, has become insolvent, or has assigned or subcontracted any part of the Work without the City’s consent. Should such termination occur, the Contractor will be paid the actual amount due based on Contract Unit Prices or lump sums bid and the quantity and quality of the work completed and in place at the time of termination, less damages caused to the City by the Contractor’s action or inaction. In the event of such termination of control, the City may do any one, or combination of, the following: II-B-25 Agreement No. 7526 1. Serve written notice upon the Surety on its Faithful Performance Bond demanding satisfactory compliance with the Contract. In such event the Surety will, within 5 days, assume control and perform the Work as successor to the Contractor; 2. The City may perform the Work itself and deduct the cost thereof from any payment due to the Contractor; 3. The City may replace the Contractor with a different contractor to complete the work and deduct the cost thereof from any payment due to the Contractor. Nothing herein will waive, or serve as a limitation upon, any additional remedy the City may have under these Contract Documents or applicable law. 6-7.3 Surety’s Assumption of Control Should the Surety assume any part of the Work, it will take the Contractor’s place in all respects for that part, and will be paid by the City for all work performed by it in accordance with the Contract. If the Surety assumes the entire Contract, all money due to the Contractor at the time of its default will be payable to the Surety as the Work progresses, subject to the terms of the Contract. If the Surety does not assume control and perform the Work within 5 days after receiving notice of cancellation, or fails to continue to comply, the City may exclude the Surety from the premises. The City may then take possession of all material and equipment and complete the Work by City’s forces, by letting the unfinished work to another contractor, or by a combination of such methods. In any event, the cost of completing the Work will be charged against the Contractor and its Surety and may be deducted from any money due or becoming due from the City. If the sums due under the Contract are insufficient for completion, the Contractor or Surety will pay to the City within 5 days of completion, all costs in excess of the sums due. The provisions of this subsection will be in addition to all other rights and remedies available to the City under applicable law. 6-9 LIQUIDATED DAMAGES Delete and replace with the following: 6-9.1 Failure to Complete Work on Time If all the work called for under the contract is not completed before or upon the expiration of the Contract Time, the City will sustain damage. Since it is and will be impracticable to determine the actual damage which the City will sustain in the event of and by reason of such delay, it is therefore agreed that the Contractor will pay to the City the sum specified in the Proposal for each and every calendar day beyond the time prescribed to complete the work not as a penalty, but as a predetermined liquidated damage. The Contractor agrees to pay such liquidated damages as are herein provided, II-B-26 Agreement No. 7526 and in case the same are not paid, agrees that the City may deduct the amount thereof from any money due or that may become due to the Contractor under the contract. Unless otherwise specified, liquidated damages will be $250 per calendar day. SECTION 7 – MEASUREMENT AND PAYMENT 7-2 LUMP SUM WORK Section 7-2, Lump Sum Work, of the Greenbook is deleted in its entirety and replace by the following: Items for which quantities are indicated as “Lump Sum,” “L.S.,” or “Job” will be paid for at the price indicated in the Proposal. Such payment will be full compensation for all costs for labor, equipment, materials and plant necessary to furnish, construct and install the lump sum item work, complete, in place, and for all necessary appurtenant work, including, but not limited to, all necessary cutting, patching, repair and modification of existing facilities, and clean up of site. Contractor will furnish three copies of a detailed schedule, which breaks down the lump sum work into its component parts and cost for each part, in a form and sufficiently detailed as to satisfy Engineer that it correctly represents a reasonable apportionment of the lump sum. This schedule is subject to approval by Engineer as to both the components into which the lump sum item is broken down, and the proportion of cost attributed to each component. This schedule will be the basis for progress payments for the lump sum work. 7-3 PAYMENT 7-3.2 Partial and Final Payments Delete and replace with the following: The closure date for the purpose of making partial progress payments will be the last working day of each month. The Contractor will prepare the partial payment invoice with measurement of the work performed through the closure date and submit it to the CITY for approval. When work is complete, the Contractor will determine the final quantities of the work performed and prepare the final progress payment, and submit it to the Engineer for approval. It will take a minimum of thirty-five (35) calendar days from the date of approving the Contractor’s invoice to make the payment to the Contractor. However, payments will be withheld pending receipt of any outstanding reports required by the contract II-B-27 Agreement No. 7526 documents, or legal release of filed Stop Payment Notices against the Contractor. In addition, the final progress payment will not be released until the Contractor returns the control set of Plans and Specifications showing the as-built conditions. The full five percent (5%) retention will be deducted from all progress payments. The Contractor will make a payment request for the retained amount, for approval by the City, upon field acceptance of the work by the City Engineer. The City Engineer upon field acceptance and receipt of the final as-built plans and any other reports or documents required to be provided by the Contractor will process a recommendation to the City Council for acceptance of the work. Not less than thirty-five (35) calendar days from the City Council acceptance of the work, the Contractor’s final payment will be made provided Stop Payment Notices or other claims have not been filed against the Contractor and/or the City by material suppliers, sub-contractors, other governmental agencies, and private property owners. Until these Stop Payment Notices are released and claims are resolved the stop payment/claim amount will be withheld from the final payment. The Contractor, however, may receive interest on the retention for the length of construction, or receive the retention itself as long as the retention is substituted with escrow holder surety or equal value. At the request and expense of the Contractor, surety equivalent to the retention may be deposited with the State Treasurer, or a State or Federally chartered bank, as the escrow agent, who will pay such surety to the Contractor upon satisfactory completion of the contract. Pursuant to PCC § 22300, the Contractor may substitute securities for retention monies held by the City or request that the City place such monies into an escrow account. The Contractor is notified, pursuant to PCC § 22300, that any such election will be at the Contractor’s own expense and will include costs incurred by the City to accommodate the Contractor’s request. Progress payment paid by the City as contemplated herein, will be contingent upon the Contractor submitting, in addition to any additional documents, an updated Contract Schedule in the form prescribed by these Contract Documents. Failure of the Contractor to submit an acceptable updated Contract Schedule will result in the City withholding partial payment, without liability to the City, until such an acceptable updated Contract Schedule is submitted. Nothing herein will allow the Contractor to suspend or slow progress of the Work. A City Council resolution established a Project Payment Account, encumbered money in the current budget, and assigned that money to the Project Payment Account which is the sole source of funds available for payment of the Contract Sum. Contractor understands and agrees that Contractor will be paid only from this special fund and if for any reason this fund is not sufficient to pay Contractor, Contractor will not be entitled to payment. The availability of money in this fund, and City’s ability to draw II-B-28 Agreement No. 7526 from this fund, are conditions precedent to City’s obligation to make payments to Contractor. 7-3.2.1 Final Payment and Termination of Agency Liability Before receiving final payment, the Contractor will execute a “Release on Contract” form which will operate as, and will be a release to the City, the City Council, and each member of the City Council and their agencies, from all claims and liability to the Contractor for anything done or furnished for, or relating to, the work or for any act of neglect of the City of any person relating to or affecting the work, except the claim against the City for the remainder, if any there be, of the amounts kept or retained as provided in Subsection 9-3 of the Standard Specifications and except for any unsettled claims listed on said form which have been filed in compliance with the requirements for making claims. 7-3.3 Delivered Materials Materials and equipment delivered or stored, but not incorporated into the work, will not be approved for progress payments. 7.4 PAYMENT FOR EXTRA WORK 7-4.2 Basis for Establishing Costs 7-4.2.3 Tools and Equipment Rental Delete the second and third paragraphs and replace with “Regardless of ownership, the rates to be used in determining the equipment usage costs will not exceed those listed for the same or similar equipment in the California State Department of Transportation publication of Labor Surcharge and Equipment Rates effective for the period of usage.” 7-4.3 MARK UP Delete and replace with the following: 7-4.3.1 Work by Contractor The following percentages will be added to the Contractor’s costs and will constitute the markup for all overhead and profits. 1) Labor ................................................ 20 2) Materials........................................... 15 3) Equipment Rental ............................. 15 4) Other Items and Expenditures ........... 15 To the sum of the costs and markups provided for in this subsection, 1 percent will be II-B-29 Agreement No. 7526 added as compensation for bonding. No other formula, e.g., the Eichleay or other method, may be used to calculate daily damages for office overhead, profit, or other purported loss. 7-4.3.2 Work by Subcontractors. When all or any part of the extra work is performed by a Subcontractor, the markup established in 7-4.3.1will be applied to the Subcontractor's actual cost of such work. A markup of 10 percent on the first $5,000 of the subcontracted portion of the extra work and a markup of 5 percent on work added in excess of $5,000 of the subcontracted portion of the extra work may be added by the Contractor. 7-4.3.3 Compensable Delays In the event that City becomes liable to Contractor for compensable delays, City agrees to pay Contractor the daily Contractor Delay Damages set forth in the Bid Form or Contractor’s actual daily delay damages, whichever is less, for each day of Compensable Delay as provided for by these Contract Documents. 7-4.4 Daily Reports by Contractor Insert the following paragraph at the end of thesubsection: If disagreement continues regarding extra work, the Contractor may seek compensation in accordance with the Claims procedure. Daily Reports required by this subsection must be made part of the Claim as supporting data for the Claim. 7-4.5 Disputes and Claims Procedure 7-4.5.1 General Consistent with PCC § 10240.6, “Claim” means a written demand or assertion by the Contractor that seeks an adjustment or interpretation of the terms of the Contract Documents, payment of money, extension of time, or other relief with respect to the Contract Documents, including a determination of disputes or matters in question between the City and the Contractor arising out of or related to the Contract Documents or the performance of the Work, and claims alleging an unforeseen condition or an act, error, or omission by the City, the Engineer, their agents or employees. “Claim” does not mean, and the Claims procedures herein do not apply, to the following: 1.

......................................................................7 ii Agreement No. 7526 Introduction PART I:INTRODUCTION This document provides a toolbox for Caltrans field pe rsonnel to aid in proper implementation of water pollution control Best Management Practices (BMPs) on the construction site. The document is organized into the following parts: Part I: Introduction briefly presents (1) the principles of erosion and sediment control, (2) common storm water pollutants on the construction site , and (3) guidelines for implementing a proper monitoring and inspection program for the construc tion site, including the use of the Storm Water Pollution Prevention Plan (SWPPP) or Water Pollu tion Control Program (WPCP) to ensure an effective water pollution control program. Part II: Project Operations and BMPs identifies typical water pollution control challenges for specific construction operations and the BMPs th at are available to meet those challenges. Part III: BMP Implementation and Troubleshooting provides guidance for installing, maintaining and troubleshooting selected BMPs from the Caltrans Storm Water Quality Handbooks, Construction Site BMPs Manual. P RINCIPLES OF E ROSION AND S EDIMENT C ONTROL The greatest water pollution threat from soil-disturbi ng activities is the introduction of sediment from the construction site into storm drain systems or natu ral receiving waters. Soil-disturbing activities such as clearing, grubbing, and earthwork increase the exposure of soils to wind, rain, and concentrated flows that cause erosion. A three-pronged approach is n ecessary to combat this storm water threat: Temporary soil stabilization practices reduce erosion associated with disturbed soil areas (DSAs). Temporary run-on control practices prevent storm water flows (sheet and concentrated) from contacting DSAs. Temporary sediment control practices reduce sedimen t caused by erosion from entering a storm drain system or receiving water. Soil stabilization BMPs reduce the erosive impact of rain on exposed soil. Run-on control practices reduce the erosive impacts by preventing storm water flows from contacting DSAs. Sediment control BMPs remove sediment from storm water by ponding a nd settling, and/or filtering prior to discharge offsite. It is imperative that soil stabilization and sediment control BMPs are implemented together to reduce the discharge of sediment from the construction site. The following conditions on construction sites contri bute to erosion caused by storm water flows: Larger areas of impermeable structures and surfaces reduce natural infiltration resulting in increased storm water flow volume and velocity. Changes to surface flow patterns cause storm water flows to be more erosive. Concentration of flows to areas that are not naturally subjected to such runoff volume increases erosion. 1 Agreement No. 7526 Introduction Proper management of a construction project minimizes or prevents soil erosion and sediment discharges. Good construction management for soil conservation requires an understanding of the following basic principles: Soil Erosion Control The First Line of Defense Soil stabilization is a key component in the control of erosion. By stabilizing DSAs with covers or binders, the exposed soils are less likely to erode from the effects of wind or rain. Prevent Storm Water Flows from Contacting DSAs The Second Line of Defense Another key component in the control of erosion is the diversion of storm water flows around DSAs or the conveyance of flows through DSAs in a non-erosive manner. Sediment Control The Last Line of Defense Storm water runoff may originate from active or inac tive DSAs whether or not proper erosion and/or run-on controls have been implemented. Impl ementing proper sediment control BMPs can reduce sediment amounts in storm water discharges. Combine Soil Erosion and Sediment Control Effective Protection An effective combination of soil erosion and sediment controls should be implemented to prevent sediment from leaving the site and/or entering a storm water drainage system or receiving water. Soil stabilization and other erosion control BMPs ar e not 100 percent effective at preventing erosion. Soil erosion control BMPs must be supported by sediment control BMPs to capture sediment on the construction site. Sediment control BMPs alone are not 100 percent e ffective primarily due to their capacity limits. To be effective for storm water protection, the amount of sediment must be reduced at the source using soil erosion control BMPs, and then sediment contro l BMPs are used to further reduce the sediment that leaves the site or enters the storm drain system. Inspection and Maintenance Ensure Protect ion for the Duration of the Project Inspection and maintenance are required for all BMPs (soil stabilization, run-on control, and sediment control) to maintain effectiveness for reducing or eliminating the amount of sediment that leaves a site. C OMMON P OLLUTANTS ON THE C ONSTRUCTION S ITE There are a number of potential storm water pollutant s that are common to Caltrans construction sites. The soil-disturbing nature of construction activities and the use of a wide range of construction materials and equipment are the sources of contaminants with the potential to pollute storm water discharges. Common construction activities that increase the pot ential for polluting storm water with sediment include: Clearing and grubbing operations Demolition of existing structures Grading operations Soil importing and stockpiling operations Clear water diversions Landscaping operations Excavation operations 2 Agreement No. 7526 Introduction Common construction materials with the potential to c ontribute pollutants, other than sediment, to storm water include the following: Vehicle fluids, including oil, grease, petroleum, and coolants Asphalt concrete (AC) and Portland cemen t concrete (PCC) materials and wastes Joint seal materials and concrete curing compounds Paints, solvents, and thinners Wood products Metals and plated products Fertilizers, herbicides, and pesticides Construction-related waste must also be managed to prevent its introduction into storm water. Typical waste on construction sites includes: Used vehicle fluids and batteries Wastewater from vehicle cleaning operations Green waste from vegetation removal Non-storm water from dewatering operations Trash from materials packaging, employee lunch/meal breaks, etc. Contaminated soils Slurries from sawing and grinding operations Wastewater/waste from concrete washout operations Hazardous materials waste Sanitary waste M ONITORING AND I NSPECTION P ROGRAM The Resident Engineer is responsible for ensuring th at Caltrans personnel monitor the contractor’s water pollution control practices and maintain complian ce with the approved project SWPPP/WPCP. This includes reviewing the contractor’s SWPPP/WPCP, reviewing written inspection reports, and conducting field inspections. Caltrans Structures personnel should also be aware of the water pollution control requirements and participate in the monitoring program. Step 1: Do Your Homework a. Review the Storm Water Quality Handbooks: Construction Site BMPs Manual. Caltrans personnel with storm water responsib ilities should familiarize themselves with BMP requirements. In particular, become familiar with (1) the rainy season dates for your geographical area, (2) the definitions of DSA, active DSA, and non-active DSA, and (3) the requirements for soil stabilization and sediment control BMPs for the season and specific Rainfall Area. b. Review the Project Plans. Review the Project Plans in the context of stor m water pollution control. Visualize storm water run-on and runoff flow patterns when reviewing the plans. Review the general layout and existing drainage courses. Identify potential problem areas where storm water may run onto the site or discharge off site. 3 Agreement No. 7526 Introduction Identify the locations where structures are being constructed or modified. Be familiar with the right-of-way and easement limits. Determine the limits of clearing and grubbing activities. Identify the project phase or stage. Try to de termine DSAs and Environmentally Sensitive Areas (ESAs). Is the next phase going to include soil-disturbing activities and is it scheduled within the rainy season? Do the DSAs have provisions in the plans for permanent erosion control? Determine if permanent erosion control can be placed when activity in the DSA is complete. c. Review the Special Provisions Review the Special Provisions for site-specifi c water pollution control requirements such as: (1) permits for the construction project, (2) limits on active DSAs, (3) rainy season dates and requirements, (4) minimum BMP requirements, (5) BMP maintenance and inspection requirements, and (6) final erosion control requirements. Final erosion control requirements include (1) required products, (2) application process, (3) application rate, (4) seeding window, and (5) planting requirements. The Special Provisions also include a section on water pollution control permits or requirements imposed on the project by other agencies. Typical agencies include the California Department of Fish and Game, Army Corps of Engineers, local flood control agencies, and others. There may be special requirements for water bodies or ESAs that need special water pollution control consideration. Review the Special Provisions bid items related to water pollution control. There may be lump sums or unit prices for water pollution control items including SWPPP/WPCP preparation, permanent erosion control, and temporary erosion and sediment controls. Review the Special Requirements section of the Sp ecial Provisions for site-specific activities such as: (1) dewatering, (2) sampling and analysis, (3) BMP maintenance cost allocation between Caltrans and the contractor, and (4) sanctions against the contractor in the event of non- compliance with the water pollution control requirements. d. Review the SWPPP/WPCP. The SWPPP or WPCP for the project is the cont ractor’s plan to ensure conformance with Caltrans’ water pollution control requirement s on the construction site. The SWPPP/WPCP contains details about the BMPs to be used on the site, their locations, implementation timeframes, and inspection and maintenance sche dules. The contractor must comply with the approved SWPPP/WPCP. If conditions change on the construction site that impact storm water pollution controls, the contractor must amend the SWPPP/WPCP. In the SWPPP, Section 200 contains the approval signature and lists any amendments. Section 300 describes unique features of the construction site and contains the construction and water pollution control schedules. Section 500 identifi es the BMPs selected for soil stabilization, sediment control, non-storm water controls, waste management, and materials disposal controls and references locations on the vicinity map and water pollution control drawings. In a WPCP, Section 10 contains the approval signatures. Section 20 describes the unique features of the site and contains the schedule. Section 30 identifies the selected BMPs, the vicinity map and water pollution control drawings. Section 40 contains any WPCP amendments. e. Review the Contractor’s Schedule . The accepted Baseline schedule as well as the m onthly updates and three-week “look-ahead” schedules are important references to better an ticipate which BMPs will be implemented or 4 Agreement No. 7526 Introduction needed. A project schedule is required in both SWPPPs and WPCPs and must show how the rainy season relates to soil-disturbing and re-stabilization activities and must also show major activities sequenced with implementation of BMPs. Step 2: Establish an Inspection Schedule a. Prior to the rainy season, inspect the site to en sure that the contractor has the necessary materials to stabilize required DSAs and to implement the necessary sediment controls. b. Year round, inspect the construction site prior to a forecast storm, after a rain event that causes runoff from the construction site, and at 24-hour intervals during an extended rain event. c. Conduct inspections at other frequenci es as required by the Special Provisions. d. Work with the Project Storm Water Coordi nator, the District Construction Storm Water Coordinator, and SWTF Inspectors during site inspections and to receive assistance when necessary. Step 3: Conduct the Inspection a. Use the most recent Storm Water Quality Construction Site Inspection Checklist to document the inspection. The checklist is provided in Attachment H of the Caltrans Storm Water Quality Handbooks, SWPPP and WPCP Preparation Manual. This is the same checklist used by the contractor for conducting inspections. Instructions for using the checklist are also provided in Attachment H. b. Encourage the contractor to participate in the inspection. This provides the opportunity for verbal feedback and discussion. c. If the project involves significant structures work, encourage the Structures representative or inspector to participate in the inspection. Take a copy of the most current and approved site plan(s) and SWPPP on the inspection for identification of site features and for taking notes at specific areas. d. Fill out the Inspection Checklist and add findings in writing. Use clear and concise language and give specific locations where problems were observed. e. Take photographs during the inspection to document the existing conditions. This is especially important if the contractor does not attend the inspection. When photos of problem areas are taken, try to follow up with photos showing corrections. f. Inspect the entire site, including the perimeter, especially where there is potential for run-on or discharge from the site. Look for areas of potentia l concentrated flows and for adjacent water bodies or drainage facilities that may be affected by discharges from the site. Start the inspection at the lowest point, or the area with the high est potential for discharge. Inspect all potential discharge points. The SWPPP/WPCP should identify discharge points, however, there may be areas with discharge potential that were not identified in the SWPPP/WPCP. g. Inspect the contractor’s yard(s), where required. h. Look for changes in construction or site conditions that may require an amendment to the SWPPP/WPCP. 5 Agreement No. 7526 Introduction i.Inspect for proper implementation of non-storm water management BMPs and waste management and materials pollution control BMPs. j.For inspections during the rainy season, evaluate active and non-active DSAs. (The Resident Engineer should periodically evaluate the classification of construction areas as active DSAs or non-active DSAs.) Determine the total area of DS A and compare it to the limit for DSAs in the Special Provisions. If the existing DSA exceeds the limit, identify areas that can be stabilized to reduce the amount. Active DSAs require protection pr ior to the onset of rain. Evaluate erosion and sediment control BMPs based on the requirements related to Rainfall Area, season and active/non-active status as defined in the SWPPP/WP CP and BMP Manual. Be sure to inspect the entire site during a rain event, especially when run-off from the site occurs. Confer with the District Construction Storm Water Coordinator as to the district’s definition of a rain event and maintain weather reports in the SWPPP file. k. During the non-rainy season, identify the active and non-active DSAs. Depending on the Rainfall Area, DSAs may continue to require erosion and sediment control BMPs during the non- rainy season. l. For individual BMPs, note if the BMP is properly installed. Also note if the BMP is in need of repair or maintenance. Step 4: Report Inspection Results a. If the Resident Engineer did not attend the in spection, communicate the results to the Resident Engineer. b. Ideally, observations should be discussed with the contractor during the inspection. c. Missing BMPs and non-compliance issues must be communicated to the contractor. Refer to the contractor’s SWPPP/WPCP for required BMPs. Step 5: Follow-up with Corrective Measures The contractor must install missing BMPs and correct improperly installed or damaged BMPs immediately or by a date and time as approved in writing by the Resident Engineer. In any event, corrections must be made prior to the next rain event. 6 Agreement No. 7526 Project Operations and BMPs PART II: PROJECT OPERATIONS AND BMPS Table 1 identifies individual BMPs that are appli cable to specific construction operations. The BMPs listed in the table are for general consideration dur ing each phase of operations. The indicated BMPs may not be applicable to every construction operation, nor is every possible BMP listed for each construction operation. The Resident Engineer should determin e the appropriateness of an individual BMP to a construction site.

Applications Delineate Environmentally Sensitive Areas (ESAs) Delineate areas where no construction activities are planned Delineate areas where construction activities will occur at a later date Delineate areas outside the project right-of-way or boundary Key Points Areas to be protected should be delineated prior to clearing and grubbing operations or other soil- disturbing activities. It is also appropriate for areas where no construction activity is planned or where activity is planned for a later date (Photo 1). Areas of existing vegetation that are scheduled for preservation should be clearly marked with a temporary fence (Photo 2). Minimize disturbance by locating temporary roadways, storage facilities, and parking areas away from preserved vegetation. Photo 1 Photo 2 Instruct employees, workers, surveyors, and subcontractors to honor protective devices. Maintain any existing irrigation systems and vegetation. Keep equipment away from trees to prevent root a nd trunk damage. Trenching should be as far away from tree trunks as possible, typically outside the drip lin e. Trenches should be filled in as soon as possible to avoid root drying. Fill trenches carefully and tamp the soil to fill in air pockets. Never expose roots to the air. 11 Agreement No. 7526 Preservation of Existing Vegetation SS-2 Preventive Measures and Troubleshooting Guide Field Condition:Common solutions are: Vehicles and equipment run into or over Clearly mark areas of preservation, and instruct workers to vegetation that is to be preserved.honor those areas.

Applied hydraulic mulch will he lp protect bare soil from water and wind erosion. Bonded Fiber Matrix (BFM) is another soil stabilizer alternative to hydraulic mulch. Applications Temporary protection for DSAs until permanent vegetation is established Temporary protection for DSAs that will be re-disturbed following an extended period (1 to 3 months) of inactivity Key Points Wood fiber mulches are mixed in a hydroseeder and applied as liquid slurry. Material is applied from a spray gun on a tower (Photo 1) or from a hose (Photo 2). Photo 1 Photo 2 A hydraulic matrix, as opposed to a basic wood fiber hy draulic mulch, consists of a wood fiber base layer and a paper fiber top layer mixed with a binding agent and applied as a liquid slurry. Paper based hydraulic mulches alone shall not be used for temporary soil stabilization applications. A bonded fiber matrix (BFM) consists of a continuous layer of elongated wood fiber strands mixed with a bonding agent. Again, the material is applied as a liquid slurry. Once dried, a high strength, porous, and erosion resistant mat is created (Photo 3). 13 Agreement No. 7526 Hydraulic Mulch SS-3 Photo 3 Do not over spray onto the traveled way, sidewalks, lined channels, etc. (Photo 4). In addition, ensure that areas to be sprayed will rema in inactive or undisturbed. This slope was disturbed after bonded fiber matrix was applied (Photo 5).

Do not use to stabilize areas with swift moving concentrated flows. 14 Agreement No. 7526 Hydroseeding SS-4 SS-4 H YDROSEEDING Hydroseeding typically consists of applying a mixtur e of fiber, seed, fertilizer, and stabilizing emulsion with hydro-mulch equipment to temporarily protect exposed soils from erosion by water and wind. Applications Temporary protection for DSAs until permanent vegetation is established Temporary protection for DSAs that will be re-distu rbed following an extended period (6 to 12 months) of inactivity Key Points Select a hydroseeding mixture by evaluating site conditions with respect to: Soil conditions and soil type. Site topography - steep slopes are difficult to protect with temporary seeding. Season and climate - seeding during summer or in arid areas may limit germination and plant establishment. Water availability - temporary or permanent irri gation may be needed for germination and plant establishment. Sensitive adjacent areas - seeding should be compatib le with adjacent ESAs. If incompatible seeding is to be used, ensure that seeds are not sprayed or blown onto the sensitive area. The Landscape Architect or the Construction Stor m Water Coordinator shall approve hydroseeding mixtures. If permanent vegetation is to be applied in th e seeded area, the temporary vegetation from the hydroseeding may need to be removed. For exampl e, grasses that inhibit compaction of soil to the required density must be removed before permanent vegetation is applied. Roughen areas to be hydroseeded by plowing or disk ing with furrows trending along the contours. Avoid over spraying onto sidewalks, lined drainage channels, roadways, or existing vegetation (Photo 1). All seeded areas should be inspected for failures.

Do not use to stabilize areas with swift moving concentrated flows. 16 Agreement No. 7526 Soil Binders SS-5 SS-5 S OIL B INDERS Soil binders are materials applied to the soil surface to temporarily reduce erosion of exposed soils on construction sites. Soil binders consist of applying and maintaining polymeric or lignin sulfonate soil stabilizers or emulsions. Applications Temporary protection for DSAs that will be re-disturbed following a period of inactivity Depending on the type of soil binder, the period of effectiveness is three months to two years Key Points Select soil binders by evaluating the site with respect to: Soil types and surface materials Suitability to the situation Performance and longevity requirements Prepare soil before applying the binder so that the binder adheres to and penetrates the soil surface. The untreated surface must be roughened (Photo 1) and must contain sufficient moisture (Photo 2) for the binder to achieve uniform penetration. Photo 1 Photo 2 Soil binders require a minimum curing time before beco ming fully effective, therefore binders should not be applied during or immediately before rainfall. When selecting a product, consider the chemical com ponents and review the Material Safety Data Sheet (MSDS). If the product has a potential for becoming a pollutant, consider using a different product. 17 Agreement No. 7526 Soil Binders SS-5 Inspect the areas of application after rainfall for signs of erosion (Photo 3). Inspect high traffic areas daily and low traffic areas on a weekly basis. High traffic areas are those exposed to daily use (vehicle or foot traffic) by c ontractor, subcontractor, or other personnel. Low traffic areas are those available for use but not in a daily manner.

Straw mu lch is used as a temporary surface cover for soil stabilization on DSAs until soils can be prepared for re-v egetation. It is also used in combination with temporary and/or permanent seeding strategies to enhance plant establishment. Applications Used in combination with temporary and/or Key Points Straw mulch must be evenly distributed on the soil surface (Photo 1). Proper application rates should be followed so that mulch covers the soil in a uniform layer without any visible bare spots. Straw mulch can be applied mechanically or by ha nd (Photo 2). Mechanical application involves a straw blower (Photo 3) and may require an access road or driving surface capable of supporting the equipment. When using a straw blower, schedule the appli cation to avoid excessive windblown straw. Manual application is time and labor inte nsive and should be used only on small areas or where equipment access is not feasible. Photo 1 Photo 2 The preferred method for anchoring straw mulch in place is to use a tackifier. Other methods for anchoring the mulch include crimping (Photo 4), punching, or track walking. Crimping and punching are mechanical methods of anchoring the mulch to the soil. Track walking should be used only where rolling is impractical. Inspect straw mulches prior to and after rainstor ms. Repair any damaged ground cover and re-mulch exposed areas of bare soil. 19 Agreement No. 7526 Straw Mulch SS-6 Photo 3Photo 4 Preventive Measures and Troubleshooting Guide Field Condition:Common solutions are: Anchor straw mulch in place by applying a tackifier, crimping, punching, or track Mulch blows away. walking.

Typically these measures are used on slopes near ESAs, as a quick stopgap measure, and when DSAs are particularly difficult to stabilize. Applications Steep slopes that are generally steeper than 1:3 (V:H) Slopes where the erosion potential is high Disturbed areas where plants are slow to develop Stockpiles Slopes adjacent to water bodies in or near ESAs Key Points There are many types of erosion control blankets and mats available (Photo 1). Select a product appropriate for the application a nd site conditions. Selection criteria include: (1) effectiveness for reducing erosion, flow velocity, and runoff; (2) acceptability for environmental compatibility, institutional / regulatory requirements, and visual impact; (3) co mpatibility with native plants, moisture retention, temperature modification, and open space coverage; (4) durability, longevity, ease of installation; and (5) maintenance frequency. Site preparation is essential to ensure that blankets and mats perform as intended. Remove all rocks, clods, vegetation or other obstructions and re-grade to allow the blanket or mat to come into complete contact with the soil. Improper slope preparation prev ents the blanket from fully contacting the soil, and allows water to flow under the blanket (Photo 2). Photo 1 Photo 2 Install the product starting from the top of the slope (Photo 3), anchored in a 150 mm by 150 mm (6 in by 6 in) trench that is backfilled and tamped firmly. Unroll the blankets down the slope, laying them loosely and stapling every 1 m (3 ft). Do not stretch blankets. Ensure that the blanket maintains direct contact with the soil. Overlap the edges of adjacent pa rallel rolls by 50 mm to 75 mm (2 in to 3 in). 21 Agreement No. 7526 Geotextiles, Plastic Covers, Erosion Control Blankets & Mats SS-7 Photo 3 Inspect blanket and mat installations periodically and after significant rainstorms for signs of erosion or undermining. Repair or replace any failures immediately. If washout or breakage of material occurs, re- install material after repairing damage to slope or channel.

Wood mulch provides temporary or short-term soil stabilization primarily for landscaping projects. Applications Temporary protection of DSAs pending estab lishment of permanent vegetative cover As a permanent non-vegetative ground cover on slopes Key Points Select wood mulch products appropria te for the application and site conditions. Prior to placement, consult with the District Landscape Ar chitect to ensure that the mulch is compatible with planned future projects. After existing vegetation has been removed, roughe n embankment and fill areas by rolling with a punch type roller or track walking (Photo 1) before applying the wood mulch. Photo 1 Mulch depth depends on the product selected such as green material or shredded wood (Photo 2). Distribute shredded wood mulch evenly (Photo 3) across the soil to a depth of 50 mm (2 in) to 75 mm (3 in). Mulch composed of recycled green waste should be applied to a maximum depth of 50 mm (2 in). Inspect and maintain mulch to ensure that it last s long enough to achieve the erosion control objectives. 24 Agreement No. 7526 Wood Mulching SS-8 Photo 2Photo 3 Preventive Measures and Troubleshooting Guide Field Condition:Common solutions are: Remove existing vegetation and roughen embankment and Area was improperly dressed before application. fill areas by rolling with a punch type roller or by track walking.

Applications To convey surface runoff down sloping land Along paved surfaces to intercept runoff Along the top of slopes to divert surface flow from slopes To divert and direct runoff towards stabilized drainage systems Below steep grades where runoff begins to concentrate Key Points It may be necessary to use other water pollution contro l practices such as check dams, plastic sheeting, or blankets to prevent scour and erosion in the swales, dikes, and ditches. Select flow velocity for ditches, swales, and dik es based on careful evaluation of potential risk due to erosion, over topping, flow backup, washout, and dr ainage flow patterns for each project. In some cases the drainage swale may need to be constructed with asphalt concrete (Photo 1). Photo 1 Care must be applied to correctly size and locate earth dikes, drainage swales, and lined ditches. Excessively steep, unlined dikes and swales may be subj ect to erosion and gully formation. Earth dikes, drainage swales and ditches are not suitable as sediment trapping devices. Inspect temporary measures prior to the rainy season, after rainfall events and regularly (approximately once every two weeks) during the rainy season. Insp ect channels, embankments, and ditch beds for erosion, washout, and accumulation of sediment and debris. Repair or replace lost riprap, linings, or soil stabilization as needed. 26 Agreement No. 7526 Earth Dikes, Drainage Swales & Ditches SS-9 Preventive Measures and Troubleshooting Guide Field Condition (Earth Dikes):Common solutions are: Dikes wash out.

Applications Outlets of pipes, drains, culverts, slope drains, diversion ditches, swales, conduits, or channels Outlets located at the bottom of mild to steep slopes Outlets subject to intense water flows Outlets that carry continuous flows of water Points where lined conveyances discharge to unlined conveyances Key Points The minimum riprap diameter is determined by the outlet diameter, discharge volume, and apron length. Outlets with slopes greater than 10% need additional protection. Flow rate and local climate may dictate whether loose rock (Photo 1) or grouted riprap is appropriate. High flows may wash loose rock away. Grouted riprap may break up in areas of freeze and thaw. Flows from unprotected pipe outlets can result in severe erosion (Photo 2). Use a flared end section or riprap at the outlet to reduce flow velocity and erosive potential of concentrated flows. Photo 1 Photo 2 Carefully place riprap to prevent damage to underlyi ng filter fabric. Where large riprap is used, the underlying filter fabric may need to be protected with a rock blanket. Inspect temporary velocity dissipation devices prior to the rainy season, after rainfall events and regularly (approximately once every two weeks) during the rainy season. Inspect aprons for riprap displacement or damage to underlying fabric. Inspect for scour ben eath the riprap and around the outlets, and repair as needed. 28 Agreement No. 7526 Outlet Protection/Velocity Dissipation Devices SS-10 Preventive Measures and Troubleshooting Guide Field Condition:Common solutions are: Replace riprap with a larger diameter based on the pipe Riprap washes away. diameter and discharge velocity.

Slope drains are used with lined ditches to convey surface flow away from slope areas to protect cut or fill slopes. Applications Where concentrated flows are directed over a slope Key Points Severe erosion may result if a slope drain fa ils due to over topping or pipe separation. Limit the area draining to a slope drain to 4 ha (10 ac) per pipe. Large areas may require the use of a rock- lined channel or a series of pipes. The maximum slope gradient is generally limited to 1:2 (V:H), as the ability to dissipate water velocity from steeper slopes is difficult. Install slope drains perpendicular to the slope contour (Photo 1). Compact the soil around and under the slope drain inlet, outlet, and along the length of the pipe . Protect the pipe inlet with filter fabric or flared end sections for pipes that are greater than 300 mm (12 in) in diameter. Ensure that pipe connections are watertight. Securely anchor and stabilize th e pipe and appurtenances into the soil. Photo 1 Protect outlet with riprap or velocity dissipation de vices. For high-velocity discharges, reinforce riprap with concrete or reinforced concrete devices. It may be necessary to capture discharge and allow sediment to settle out. Inspect before and after each rain event and twice monthly until the tributary drainage area has been stabilized. Inspect outlets for erosion and downstream scour. In the event of scour, reduce the flows going into the channel unless other preven tive measures can be implemented. 30 Agreement No. 7526 Slope Drains SS-11 Preventive Measures and Troubleshooting Guide Field Condition:Common solutions are: Reconnect pipe sections.

Application Below the toe of slopes as required Down slope of exposed soil areas Around temporary stockpiles as required Key Points Install on a relatively level contour. This means the barrier should be installed as close as possible to a level horizontal plane near the toe of the slope (Phot o 1). Turn the end of the barrier up the slope to prevent ponded water from escaping around the end (Photo 2). Photo 1 Photo 2 A silt fence should be placed with a setback of at l east 1 m (3 ft). Where a 1 m (3 ft) setback is not practicable due to site conditions, the fence may be c onstructed at the toe of slope but should be placed as far from the toe as practicable to increase the ponding area and allow sediment to settle out. The bottom of the silt fence must be keyed in or wa ter may flow underneath (Photo 3). A trench should be excavated along the proposed layout line of the fence. Af ter the silt fence stakes have been driven into the trench, backfill over the fence fabric and compact (Photo 4). 32 Agreement No. 7526 Silt Fence SC-1 Photo 3Photo 4 For silt fence installed on a level contour with long reaches, install cross barriers at a minimum of 150 m (500 ft) intervals. For silt fence not installed on a le vel contour, install cross barriers, at a minimum, where the change in elevation equals 1/3 the height of the silt fence. Do not install silt fence across intermittent or pe rmanent streams, channels, or any location where concentrated flow is anticipated (Photos 5 and 6). Photo 5Photo 6 Perform inspection before and after rain events, ev ery 24 hours during extended rain events, and weekly throughout the rainy season. Should silt fence fabric tear (Photo 7) or decompose, replace immediately. Remove sediment deposits (Photo 8) when the sediment accumulation reaches 1/3 of the barrier height. 33 Agreement No. 7526 Silt Fence SC-1 Photo 7Photo 8 Preventive Measures and Troubleshooting Guide Field Condition:Common solutions are: Remove sediment.

Applications Where storm water can enter a drainage system or receiving water from a construction area At outlets of DSAs between 2 and 4 ha (5 and 10 ac) in size Key Points 33 Desilting basins shall be designed to have a capacity of 100 m of storage for every 1 ha (55 yd per acre) of contributory area. Basin storage capacity is measured from the top of the basin to the principal outlet. Basins must be designed to drain within 72 hours follo wing storm events. Basins with levees greater than 33 1.5 m (5 ft) in height or with an impounding capacity of 1000 m (1300 yd) or greater shall be designed by a professional Civil Engineer registered with the state of California. The basin inlet shall be located to maximize travel di stance to the basin outlet. The outlet structure should be placed as far away from the inlet structure as possi ble to maximize travel distance and allow suspended sediment to settle out. The length of the basin shall be more than twice the wi dth of the basin. Basin depth must not be less than one 1 m (3 ft) or greater than 1.5 m (5 ft). Check the approved SWPPP for actual dimensions. Basins generally require excavation of large surface areas so that sediment will settle out efficiently. The availability of right-of-way may limit basin size or de ployment on construction sites. Basins may not be located in live streams. Basins may requi re protective fencing to ensure safety. Inspect basins before and after rainfall events, w eekly during the rainy season, and at 24 hours intervals during extended storm events. Check inlet and outle t structures and spillways for signs of erosion, damage, or obstructions. Examine basin banks for seepage and structural soundness. Remove accumulated sediment when the basi n storage capacity is 1/3 full. 35 Agreement No. 7526 Desilting Basin SC-2 Preventive Measures and Troubleshooting Guide Field Condition:Common solutions are: Clean outlet pipe.

Ensure drainage area does not exceed 4 ha (10 ac). If the drainage area does exceed this limit, use other or additional BMPs. 36 Agreement No. 7526 Sediment Trap SC-3 SC-3 S EDIMENT T RAP A sediment trap is a temporary basin formed by excavation or by construction of an earthen embankment across a waterway or low drainage area and has a controlled release structure. Applications Permissible where contributing area is less than 2 ha (5 ac) Sites where storm water can enter a storm drain or receiving water from a construction area As a supplemental control for reducing sediment before it enters a drainage system or receiving water Key Points Traps should be excavated in a suitable area or by constructing a low embankment across a swale where failure would not pose a risk to life or property. Traps should provide access for maintenance, including sediment removal. The trap inlet shall be located as far away from th e trap outlet to maximize travel distance and allow suspended sediment to settle out (Photo 1). The length of the trap shall be more than three times the width (Photo 2). Traps with levees greater than 33 1.5 m (5 ft) in height or with a storage capacity greater than 1000 m (1300 yd) shall be designed by a professional Civil Engineer registered with the stat e of California. Check the approved SWPPP for actual dimensions. Photo 1 Photo 2 Traps generally require excavation of large surface areas to permit settling of sediment. The availability of right-of-way may limit their size or deployment on construction sites. Sediment traps should be limited to drainage areas of 2 ha (5 ac) or less. Traps ma y not be located in live streams. Traps may require protective fencing to ensure safety. 37 Agreement No. 7526 Sediment Trap SC-3 Traps should be inspected before and after rainfall events, weekly during the rainy season, and at 24-hour intervals during extended storm events. Check inle t and outlet structures and spillways for signs of erosion, damage, or obstructions. Examine trap banks for seepage and structural soundness.

Consider other or additional BMPs. 38 Agreement No. 7526 Check Dam SC-4 SC-4 C HECK D AM A check dam is a small structure constructed of rock or gravel bags placed across a natural or man-made channel or drainage ditch. Check dams reduce scour and channel erosion by reducing flow velocity and encouraging sediment to settle out. Applications In small open channels that drain 4 ha (10 ac) or less In steep channels where storm water r unoff velocities exceed 1.5 m/s (5 ft/s) In drainage ditches or channels in which grass linings are being established In temporary ditches where a short-term service do es not warrant establishment of erosion resistant linings In combination with other BMPs such as sediment basins and traps Key Points Install check dams 5 m (16 ft) from the outfall device and at regular intervals along the channel based on the erosion characteristics and slope degree of the drainage swale (Photo 1). Swales that are very steep or have a high potential of eroding require check dams placed closer together. Check dams should be placed at a height and distance as to allow small pools to form behind them but allow high velocity flows (typically a 2-year storm or larger) to safely flow over them without an increase in upstream flooding or damage to the check dam. Check dams should be constructed to pond runoff flows so that the backwater from the downstream ch eck dam reaches the toe of the upstream dam (Photo 2). Photo 1 Photo 2 Check dams should not be placed in live streams or in channels that are already grass-lined unless erosion is expected, as existing vegetation may be damaged. Check dams are not appropriate in channels that drain areas greater than 4 ha (10 ac). 39 Agreement No. 7526 Check Dam SC-4 Check dams require extensive maintenance after storm events or high velocity flows to repair damage (Photo 3). Remove sediment when it reaches 1/3 the check dam height. Photo 3 Preventive Measures and Troubleshooting Guide Field Condition:Common solutions are: Remove accumulated sediment to recover holding Too much sediment has accumulated. capacity. There is insufficient ponding area. Space check dams farther apart. Increase height of dam. The check dam is higher than the drainage Lower check dam so that it is 150 mm (6 in) lower than the channel.channel side. Ensure that the drainage area is 4 ha (10 ac) or less. Check dams wash away.Replace check dams. Consider adding more dams upstream. Wrong type of materials is used to construct Use heavier materials such as larger rocks. Do not use barrier .straw bales or silt fence. 40 Agreement No. 7526 Fiber Rolls SC-5 SC-5 F IBER R OLLS A fiber roll consists of straw, flax, or similar materi al that is rolled and bound into a tight tubular cylinder and placed at regular intervals on a slope face. Fiber rolls intercept runoff, reduce runoff flow velocity, and release the runoff as sheet flow. Fiber rolls are also used as a filter to remove sediment from runoff. Applications Along the top, face, and at grade breaks of exposed and erodible slopes Key Points Proper fiber roll installation is crucial to ensure effectiveness and performance. Fiber rolls should be placed on a level contour in a shallow trench with a maximum depth of 50 mm to 100 mm (2 in to 4 in). The fiber roll should be staked at each end and at regular intervals along its length with a maximum distance of 1.2 m (4 ft) between stakes. If more than one fiber roll is placed in a row, the ends of the adjoining rolls should be tightly abutte d together and not overlapped (Photo 1). When used to create storm water benches on a slope, the vertical spacing of the fiber rolls rows is determined by the inclination and length of the slope (Photo 2). For slopes 1:2 (V:H) and steeper and 15 m (50 ft) and greater, fiber rolls shall be placed at intervals no greater than 7.5 m (25 ft). For slopes between 1:20 (V:H) and 1:2 (V:H) and 30 m (100 ft) and greater, fiber rolls shall be placed at intervals no greater than 15 m (50 ft). Photo 1 Photo 2 Fiber rolls are acceptable for use as sediment control and may be used in conjunction with other soil stabilization methods (soil binders, mulches, et c.) (Photo 3) and/or other sediment controls. Fiber rolls are typically left in place. If they are re moved, dispose of the accumulated sediment and fill in trenches, holes, or depressions to blend in with adjacent ground contours. 41 Agreement No. 7526 Fiber Rolls SC-5 Inspect fiber rolls prior to and after rain events, a nd at least daily during prolonged rainfall. Maintenance includes replacing slumping rolls, removing accumulated sed iment, and filling in rills. If fiber rolls split, tear (Photo 4), unravel, or become ineffective, replace them immediately.

Applications Along the top, face, and at grade breaks of exposed and erodible slopes Key Points Proper gravel bag berm installation is crucial to ensure its effectiveness and performance. Gravel bag berms should be placed on a level contour along the slope (Photo 1). Gravel bags should be tightly abutted together and not overlapped (Photo 2). Photo 1 Photo 2 Bags should be made of a woven polypropylene, polyethylene or polyamide fabric, or burlap material. When full, a bag should be 450 mm (1.5 ft) long, 300 mm (1 ft) wide, and 75 mm (3 in) thick, with a mass of approximately 15 kg (35 lb). Bag dimensions are standardized but may vary based on locally available materials. Alternative bag sizes shall be subm itted to the Resident Engineer for approval prior to deployment. Fill material shall be 13 mm to 25 mm (1/2 in to 1 in) class 2 aggregate base that is clean and free from clay and undesirable materials. Although gravel bag berms remove some sediment, they should not be used in place of linear sediment barriers. Gravel bags are sensitive to ultraviolet light resulting in a limited durability that may make them unsuitable for long-term projects. Gravel bag berms are labor intensive. Installation, removal, and maintenance costs should be evaluated when considering this BMP. Inspect gravel bag berms weekly and prior to and af ter rainfall events during the rainy season. Repair or replace broken or ripped bags, and reshape as necessar y. Remove accumulated sediment when it reaches 1/3 the height of the berm.

Areas of concern include ingress and egress points, portions of roadway within the project limits adjacent to a freeway or other public road, and any other paved surface within project limits that is to remain after construction is complete. Applications Where sediment is tracked onto public or private roadways from the project site Key Points Sweepers should have vacuum or other mechanical attachments for collecting dirt and sediment (Photo 1). Adjust brooms regularly to maximize efficiency of sweeping operations. Never use kick brooms or sweeper attachments for the implementation of this BMP. Inspect project ingress and egress points and roadways daily for signs of tracked sediment (Photo 2). Photo 1 Photo 2 After sweeping is finished, properly dispose of sweeper waste. Sweeper waste that includes trash and debris should be disposed of at an approved dumpsite. For collected sediment that is free of trash and debris, consider incorporating the sediment b ack into the project’s earthwork operations. Designate a limited number of centralized ingress/egress locations for the site and instruct construction personnel to use only those locations for entering/exiting the project (see TC-1). 45 Agreement No. 7526 Street Sweeping and Vacuuming SC-7 Preventive Measures and Troubleshooting Guide Field Condition: Common solutions are: Install a stabilized construc tion entrance/exit at egress Sediment tracking is excessive. point.

This type of barrier is designed to intercept and slow storm wa ter sheet flow runoff. Sandbag barriers allow sediment in runoff to settle before the water leaves the construc tion site. Sandbag barriers can also be used to divert and detain moderately concentrated flows associated with ditches, swales, and storm drain inlets. Applications Along the perimeter of a site Below the toe of slopes as required Down slope of exposed soil areas Around temporary stockpiles as required Parallel to a roadway to keep sediment from paved areas To divert or direct flow Key Points When used as a linear sediment barrier for slopes, sandbags should be placed along a level contour with the end of each row turned up-slope to prevent fl ow around the ends. Due to the limited sediment holding capacity behind the bags, they should be used in conjunction with other erosion source controls such as soil binders, covers, and/or mulches to provide effective control. A sandbag barrier should be placed with a setback of at least 1 m (3 ft). Where a 1 m (3 ft) setback is not practicable due to site conditions, the barrier may be constructed at the toe of slope but should be placed as far from the toe as practicable to increase th e ponding area and allow sediment to settle out. Sandbags should be stacked in a pyramid formation (Photo 1). To do this, the base of the barrier should be the widest, with the width decreasing with each higher row. The joints between bags should be staggered for each row. Photo 1 47 Agreement No. 7526 Sandbag Barrier SC-8 For sandbag barriers not on a level contour and for longe r reaches, install cross barriers at a minimum of 150 m (500 ft) intervals to prevent concentrated flow. Sandbag materials are sensitive to ultraviolet light resulting in a limited durability that may make them unsuitable for long-term projects. Sandbag barriers ar e labor intensive. Installation, removal, and maintenance costs should be evaluated when considering this BMP. Inspect sandbag barriers weekly and prior to and afte r rainfall events during the rainy season. Repair or replace broken or ripped bags, and reshape as necessar y. Remove accumulated sediment when it reaches 1/3 the barrier height. Repair washouts and rills as needed. When no longer needed, remove the barrier and accumulated sediment then clean, re-grade, and stabilize the area.

This type of barrier is designed to intercept and slow storm water runoff. Straw bale barriers allow sediment in runoff to settle before water leaves the construction site. Applications Along the perimeter of a site Below the toe of slopes as required Down slope of exposed soil areas Around temporary stockpiles as required Key Points When used as a linear sediment barrier for slopes, straw bales should be placed along a level contour with the end of each row turned up-slope to prevent fl ow around the ends. Bales should be installed in a shallow trench with ends tightly abutted together. Straw bales placed at the toe of slopes should be set b ack at least 1 m (3 ft) from the toe. Where a 1 m (3 ft) setback is not practicable due to site conditions, th e barrier may be constructed at the toe of the slope but should be placed as far from the toe as practicab le to increase the ponding area and allow sediment to settle out. Straw bales should be placed in two rows back to back with a half-bale offset to cover the butted ends of the bales. For straw bale barriers not on a level contour and for longer reaches, install cross barriers at a minimum of 150 m (500 ft) intervals to prevent concentrated flow. Straw bale barriers should not be used in areas subj ect to highly concentrated flows (Photo 1) such as channels or live streams as they may be easily overtak en or washed away. Straw bale barriers should not be used on paved surfaces, in lined ditches, or for drain inlet protection. Consider using sandbag barriers instead. Photo 1 49 Agreement No. 7526 Straw Bale Barrier SC-9 Straw bales fall apart when removed or degrade when left in place for extended periods. They can be labor intensive to install, remove, and maintain. Inspect straw bale barriers weekly and prior to and af ter rainfall events during the rainy season. Repair or replace broken or damaged bales as necessary. Remove accumulated sediment when it reaches 1/3 the barrier height. Repair washouts or other damage as needed or required. When no longer needed, remove barrier and accumulated sediment then cl ean, re-grade, and stabilize the area. Preventive Measures and Troubleshooting Guide Field Condition:Common solutions are: Remove sediment.

Effective storm drain inlet protection allows sediment to settle out of water or filters sediment fro m the water before it enters the drain inlet. Storm drain inlet protection is the last line of sediment control defense prior to storm water leaving the construction site. Applications Where storm water surface runoff can enter a drain inlet Where disturbed drainage areas have not yet been permanently stabilized Where ponding will not encroach into traffic Where the drainage area is 4 ha (10 ac) or less Key Points Identify existing and/or planned storm drain inlets th at have the potential to receive storm water runoff and discharge from the construction site. For those drai n inlets that are to be protected, determine the most effective method to use. Consider drain inlet protection for active inlets that are downstream of DSAs. A sandbag barrier (Photo 1) is the most common type of protection due to the flexibility of its use. Sandbag barriers are constructed by placing the bags around the inlet to create a holding area that allows suspended sediment to settle. Photo 1 A filter fabric fence (Photo 2) is effective in open areas where sheet flows are low and are not expected to 3 exceed 0.14 m/s (0.5 cfs). Filter fabric fences are installed similarly to silt fences but are constructed to surround the inlet to create an enclosure. Use plastic sheeting or geotextile blankets to stabilize any DSAs within the enclosure to prevent sediment within the enclosed area from entering the inlet. 51 Agreement No. 7526 Storm Drain Inlet Protection SC-10 Photo 2 Excavated drop inlet sediment traps are typically u sed where relatively heavy flows are expected and overflow capacity is needed. A drain inlet sedimen t trap is constructed by excavating the soils surrounding the inlet to create a temporary trap that detains flows and allows suspended sediments to settle before storm water is discharged from the site. Inspect all inlet protection devices before and afte r storm events, at 24 hour intervals during extended storms, and weekly during the rest of the rainy season. Check storm drain inlet after several storms to determine if sediment is bypassing inlet protection devices. Maintenance is critical to ensure that drain inle t protection remains functional. Remove accumulated sediment when it reaches 1/3 the barrier height or 1/3 the holding capacity. For barriers, replace broken or torn bags. For fences, repair/replace fencing ma terial and re-stake fences that are damaged. Preventive Measures and Troubleshooting Guide Field Condition:Common solutions are: Ensure that soil stabilization and sediment control devices are installed upstream of inlets. Ensure that the barriers around the inlet are installed correctly. Sandbags need to be Excessive sediment is entering the inlet.tightly abutted. Filter fence needs to be keyed in so that water goes through filter fabric and not under it.

Remove drain inlet Ponded water causes a traffic concern. protection if necessary. 52 Agreement No. 7526 Wind Erosion Control WE-1 WIND EROSION CONTROL WE-1W IND E ROSION C ONTROL Wind erosion control consists of applying water or other dust palliativ es to prevent or alleviate dust nuisance. Dust control shall be applied in accordance with Caltrans standard practices. Applications On all exposed soils that are subject to wind erosion Key Points Care should be taken when applying water (Photo 1) or palliative to prevent the washing of sediment offsite or into storm drains or receiving waters. Do not apply so much that runoff occurs. Photo 1 Cover small stockpiles or small DSAs as an alternative to applying water or dust palliative. When applying palliatives or binders as a wind er osion control, refer to the manufacturer’s recommendations for guidance. Preventive Measures and Troubleshooting Guide Field Condition:Common solutions are: Increase frequency of water application. Consider using a Excessive dust leaves the site. palliative or binder on inactive areas. Water more frequently. Limit vehicle speeds. Stabilize the Vehicles kick up dust. roadway. Reduce water pressure on the water truck. Check watering Watering for dust control causes erosionequipment to ensure that it has a positive shutoff. Water less frequently.

Stabilized construction entrances are an effective method for reducing tracking of sediment from the construction site. Applications As a preventive method instead of a treatment method (e.g., sweeping or dust control) Where dirt or mud can be tracked onto public roads Adjacent to water bodies Where poor soils are encountered Key Points Site conditions may dictate the design and need for access points. Design a stabilized construction entrance/exit to support the heaviest vehicles and equipment that will use it (Photo 1). The access point should be at least 15 m (50 ft) in length or four times the circumference of the largest construction vehicle tire, whichever is greater (Photo 2). Designate access points and require all employees, subcontractors, and others to use them. Photo 1Photo 2 Grade construction entrance/exit points to prevent r unoff from leaving the construction site. Route runoff from entrances/exits through a sediment-trapping device before discharge. Stabilize the roadway with aggregate, AC, or PCC, depending on expected usage and site conditions. When access points are constructed from aggregate, aggregate should be 75 mm (3 in) to 150 mm (6 in) in diameter and at least 300 mm (1 ft) in depth. Place aggregate over a geotextile fabric. Alternative stabilization methods such as manufactured steel plates (Photo 3) or steel pipes/gratings require written approval of the Resident Engineer. The use of cold mix asphalt or AC grindings is not allowed. 54 Agreement No. 7526 Stabilized Construction Entrance/Exit TC-1 Inspect and maintain stabilized construction entr ance/exit points. Routinely check for damage and effectiveness (Photos 4 and 5). Remove accumulated sediment (Photo 6) and/or replace stabilization material as needed.

For storm water protection, it should be designed to control dust and erosion created by vehicular traffic. Applications Where displacement of soil occurs because of vehicular traffic during wet weather Where dust control is a problem during dry weather Adjacent to water bodies Where poor soils are encountered Key Points Site conditions may dictate the design and need for stabilized construction roadways. Design the roadway to support the heaviest vehicles and equipment that will use it. Grade the road way to prevent runoff from leaving the construction site. This may require the c onstruction of a drainage ditch to collect and convey runoff. Stabilize the roadway with aggregate, AC, or concre te, depending on expected usage and site conditions. Aggregate diameter should be between 75 mm (3 in) and 150 mm (6 in) and at least 300 mm (1 ft) in depth. Place aggregate over a geotextile fabric. The use of cold mix asphalt or AC grindings is not allowed. Inspect and maintain the stabilized construction roadway routinely. Re-grade the roadway as necessary. Check for damage and repair as necessary or as directed by the Resident Engineer. Preventive Measures and Troubleshooting Guide Field Condition:Common solutions are: Properly grade roadway so that runoff is kept on site.

Vehicles kick up dust.Re-stabilize the roadway. 56 Agreement No. 7526 Water Conservation NS-1 NON-STORM WATER MANAGEMENT NS-1W ATER C ONSERVATION Water conservation involves the use of practices that reduce the amount of water used for a given activity. If less water is used, the potential for erosion decreases and the transport of construction-related pollutants offsite is less likely. Applications On all projects where water is used during the course of construction Key Points Watering equipment should be kept in good working order (Photo 1). Repair leaky watering equipment promptly. Photo 1 Discourage the washing of vehicles and equipment on the construction site. Workers should never wash their personal vehicles on site. Vehicles and equipment th at regularly leave the construction site should be washed offsite. Paved areas should be swept and vacuumed rather than washed off. Always protect storm drain inlets or receiving waters from sediment or other pollutants suscep tible to non-storm water run-off. When possible, direct runoff water to areas where it can percolate into the ground. When watering for dust control, ensure that watering operations do not cause erosion. 57 Agreement No. 7526 Water Conservation NS-1 Preventive Measures and Troubleshooting Guide Field Condition:Common solutions are: Water tank leaks from the outlet valve.Repair the positive shutoff valve. Do not overfill. Use other BMPs to stabilize the roadway Watering equipment overflows during filling around the filling area e.g. Stabilized Construction Roadway creating muddy and rutted areas.

Dewatering effluent that is discharged from the construction site to a storm drain or receiving water is subject to the requireme nts of the applicable National Pollutant Discharge Elimination System (NPDES) permit. Refer to the Caltrans Field Guide to Construction Site Dewatering for detailed guidance for management of dewatering operations. The District Construction Storm Water Coordinator is also available for assistance. Applications On all projects where the discharge of wa ter is to occur by mechanical means Key Points If possible, the contractor should consider managing dewatering without discharge to a storm drain or receiving water. Options include: (1) retaining the wate r on site for construction use or allowing water to evaporate/infiltrate, (2) discharging to the sanitary sewer with permission from the local agency; (3) discharging to an adjacent land or facility with permission of the owner, and (4) having the effluent transported and disposed of offsite using a Transportation, Storage & Disposal (TSD) contractor. If one of these management options is used, the water is not di scharged to a storm drain or receiving water, and the operation is not subject to an NPDES permit. If on-site management of the dewa tering operation is not the selected option, contact the Construction Storm Water Coordinator (CSWC) befo re the dewatering operation commences. In many areas of the state, uncontaminated storm water and minor discharges of non-storm water can be discharged to a storm drain or receiving water under the Caltrans General NPDES Permit. If the effluent is not visibly clear, it must be treated to remove sediment prior to discharge (Photo 1). All records related to the dewatering operation must be maintained w ith the project SWPPP and provided to the Regional Water Quality Control Board (RWQCB) upon request. No te that in RWQCB Region 1 and2,no type of dewatering discharge to a storm drain or receiving water is authorized under the Caltrans NPDES Permit – a separate Regional dewatering permit is required. For all dewatering discharges in RWQCB Regions 1 and 2 (North Coast and San Francisco Bay areas), and for many discharges of non-storm water dewateri ng (Photo 2) in all other Regions, the RWQCB must approve a discharge to a storm drain or receiving water. The RWQCB may require the contractor to apply to discharge under a separate Regional dewatering pe rmit or under a site-specific dewatering permit. Regional dewatering permits generally require the contractor to monitor (test) the dewatering effluent, to maintain monitoring records, and to submit re ports to the RWQCB about the operation. Discuss dewatering requirements with the District Construction Storm Water Coordinator. 59 Agreement No. 7526 Dewatering Operations NS-2 Photo 1Photo 2 Preventive Measures and Troubleshooting Guide Field Condition:Common solutions are: Install outlet protection or velocity dissipation device Discharge of treated water causes erosion.

Application During pavement grinding and removal During PCC paving During AC paving and resurfacing During placement of thermoplastic striping and pavement markers Key Points Remove or dispose of grindings and wastes as work progresses. Place AC pieces in embankments above the water table and cover with plastic until they are removed from the site. Remove wastes from the site immediately. Coat AC equipment with non-toxic non-foaming produc ts. Clean equipment (Photo1) offsite whenever possible. When paving equipment is kept onsite, pl ace paving equipment on plastic sheeting to capture drips or leaks (Photo 2). Dispose of hardened AC properly. Photo 1Photo 2 Do not allow wastes, such as AC pieces, PCC gri nding residue/slurry (Photo 3), sand/gravel, exposed aggregate concrete residue, or dig-out materials in to storm drains or receiving waters. Sweep, vacuum, and collect such wastes and recycle or dispose of properly. Do not apply seal coat, tack coat, slurry seal, or fog seal if rain is predicted during the application or curing period. Do not conduct digout operations in the rain. During application of seal coat, tack coat, slurry seal, or fog seal, cover drainage inlets and ma nhole covers with filter fabrics. Do not apply these materials in the rain. 61 Agreement No. 7526 Paving and Grinding Operations NS-3 Photo 3 Verify that equipment shut-off valves function properly to avoid thermoplastic leakage. Do not pre-heat, transfer, or load thermoplastic near storm drains or receiving waters. When filling the pre-heater, leave 150 mm (6 in) of space at the top of the container to prevent spills when the equipment is moved. Clean truck beds daily and recycle thermoplastic material when possible. Do not transfer or load bituminous materials near storm drains or receiving waters.

Typical types include culvert crossings, ford crossings, and bridge crossings. Temporary stream crossings prevent str eambed erosion and downstream sedimentation due to construction traffic. Applications Where appropriate permits have been secured Where construction equipment or vehicles must cross a waterway (ephemeral or perennial) Key Points Verify that applicable permits have been obtained before the stream crossing is installed. Required permits may include RWQCB 401 Certification, U.S. Army Corps of Engineers 404 Permit, and/or Department of Fish and Game 1601 Agreement. Ve rify that applicable pre-installation water sampling/testing has been completed before, and possibly during, installation. Verify that the structure design has been prepared unde r the direction of and approval of a registered civil and/or structural engineer. The structure should not constrict waterway flow such that backups or washouts occur during flood events. Culverts are accepta ble for perennial or intermittent streams and can accommodate heavy equipment loads. Fords are the least expensive but are acceptable only for dry washes/ephemeral streams during the dry season. Bridges (Photo 1) are the most expensive but are appropriate for high velocity/steep gradient streams or where restrictions in the waterway channel are not allowed. Photo 1 Construct crossings during the dry season. Stabilize adjacent construction roadways, work areas, and streambeds to prevent erosion. Minimize disturbance or removal of adjacent vegetation. If riparian vegetation is disturbed for construction of the stream crossing, the vegetation should be cut no lower than ground level and covered with a layer of clean river cobble. 63 Agreement No. 7526 Temporary Stream Crossing NS-4 Vehicles are not to be operated, stored, fueled, or main tained in wet or dry portions of a waterway without authorization of the Resident Engineer or as authorized by the Fish and Game Permit. Drip pans must be placed under all vehicles/equipment on temporary stream crossing structures that remain idle for more than one hour. Being in such close proximity to a watercourse, this BMP, and others implemented with it, must be installed correctly and maintained to prevent any discharge. Any incident of discharge requires submittal of a Notice of Non-Compliance. Inspect temporary stream crossings weekly and afte r significant rain events for water flow blockage, sediment buildup, trapped debris, structural damage, ri prap displacement, or streambed erosion. Verify that sediment buildup is removed regularly and that riprap/aggregate is replaced as needed to prevent erosion and maintain stability of adjacent areas. Ensure that temporary stream crossings are rem oved promptly when no longer needed. Remove river cobble from disturbed riparian vegetation to ensure rapid re-growth. Preventive Measures and Troubleshooting Guide Field Condition:Common solutions are: Place rock layer on slope sides. Stabilize roadway at Slopes of temporary earthen crossing erodes. crossing.

Typical structures used for clear water diversions include diversion ditches, berms, dikes, slope drains, coffer dams, pipes, and drainage and interceptor swales. Applications Where appropriate permits have been secured Where work must be performed in an active drainage system, a running stream, or a water body Key Points Verify that applicable permits have been obtained be fore the diversion is installed. Required permits may include RWQCB 401 Certification, U.S. Army Corps of Engineers 404 Permit, Department of Fish and Game 1601 Agreement, and/or Federal Emergency Ma nagement Agency requirements. If required by a permit, verify that applicable pre-installation wa ter sampling/testing has been completed before, and possibly during, installation. The structure should not constrict waterway flow such that backups or washouts occur due to fluctuations in water depth or flow volume. Materials used to c onstruct diversion structures must be free of potential pollutants such as soil, silt, sand, clay, grease, or oil. At all times during construction, operation, maintenance, and removal, sufficient water flow/ volume must be diverted to maintain downstream aquatic life (Photo 1). Photo 1 When possible, construct diversion structures during periods of low or no stream flow. Minimize disturbance and removal of adjacent vegetation. If ripa rian vegetation is disturbed for construction of the diversion, the vegetation should be cut no lower than ground level and covered with a layer of clean river cobble. The exterior of vehicles and equipment in we t areas of the diversion construction site should be free of petroleum residues and sealed so as to prevent leakage of fuels and oils into the water body if submerged. Only the bucket of an excavator/backhoe may operate in a water body. The main body of the equipment is not to enter the water portions of th e water body except to cross the stream to access the work site. 65 Agreement No. 7526 Clear Water Diversion NS-5 Barriers should be installed to prevent muddy wate r from flowing from adjacent construction activity to the stream. Drip pans must be placed under all st ationary equipment and vehicles located over water diversions that remain idle for more than one hour. Being in such close proximity to a watercourse, this BMP, and others implemented with it, must be installed correctly and maintained to prevent any discharge. Any incident of discharge requires submittal of a Notice of Non-Compliance. Inspect diversion structures weekly and after significant rain events for damaged linings, sediment buildup, trapped debris, or reduced slope protection. Ensure that debris is removed and linings are repaired promptly. Preventive Measures and Troubleshooting Guide Field Condition:Common solutions are: Place drip pans under all vehicl es and equipment that are Vehicles and equipment parked over water bodies placed on structures over water bodies that will be idle for leak fluids. more than one hour.

Applications Construction projects that disturb or occur within stream channels and associated riparian areas. Key Points Planning should consider scheduling, avoidance of in-stream construction, minimizing disturbance area and construction time, using pre-disturbed areas, sel ecting crossing location, and selecting equipment. Preservation of existing vegetation (SS-2) in a str eambank provides water quality protection, streambank stabilization, and riparian habitat. Hydraulic mu lch (SS-3), hydroseeding (SS-4), soil binders (SS-5), straw mulch (SS-6), or a combination may be used on disturbed streambanks to provide temporary soil stabilization. Be sure to review the limitations of each so that a selection of the most appropriate one for the given conditions may be made. Also consider possible use of other soil stabilization and sediment control BMPs provided the application is appr opriate and the limitations are not applicable. The primary goal while working in a stream is minimizing turbidity. There are three general ways to achieve this: construct a water diversion away from the work area, implement a water barrier around the work area, or employ practices that minimize sediment suspension. Inspect BMPs and equipment daily and ensure necessar y repairs for both are done in a timely manner. If a piece of equipment leaks, remove it from the stream immediately for repairs. Preventive Measures and Troubleshooting Guide Field Condition:Common solutions are: Equipment in stream leaks fluids.Remove it immediately for repairs.

Notify the Construction Storm Water Coordinator of potential non-compliance. Clean up as much of the waste as possible. Place washout at least 15 m (50 ft) from drainage Concrete washout discharges into storm drain.facilities or receiving waters. Ensure the washout is designed to contain the volume of anticipated wastes. Protect storm drain while conducting washout with inlet cover, sandbags or other BMP. Drivers wash out trucks at locations of their Place sign at washouts and instruct drivers of the washout choosing.locations. 100 Agreement No. 7526 Sanitary/Septic Waste Management WM-9 WM-9S ANITARY/S EPTIC W ASTE M ANAGEMENT This BMP includes procedures to prevent the introduc tion of wastes from construction site toilet facilities to storm drains or receiving waters. Applications All construction sites that use temporary or portable sanitary/septic waste systems Key Points Temporary sanitary facilities should not be located near drainage facilities (Photo 1) or receiving waters, nor should they be located in areas that will collect water (Photo 2). If the site is deemed to be a high wind area by the RE, the facilities shall be secured to prevent overturning. Photo 1Photo 2 Discharges direct to the sanitary sewer should be in compliance with local health agency and sewer district requirements. Ensure that the temporary f acility is properly connected to the sanitary sewer to prevent illicit discharges. Waste water shall not be discharged or buried within the highway right-of-way (Photo 3). Ensure that any on-site disposal systems comply with local health agency requirements. 101 Agreement No. 7526 Sanitary/Septic Waste Management WM-9 Photo 3 The contractor’s Water Pollution Control Manager (W PCM) shall monitor sanitary/septic waste storage and disposal procedures weekly. Ensure that the san itary/septic facilities are maintained in good working order and wastes are transported offsite by a licensed service. Preventive Measures and Troubleshooting Guide Field Condition:Common solutions are: Place sanitary facility on level surface and out of drainage Sanitary facilities tip over.paths or traffic areas. Use Spill Prevention and Control (WM-4). Sanitary facility leaks.Repair or replace sanitary facility. Place sanitary facility away from drainage inlets or Sanitary facility is cleaned onsite near storm drain.receiving waters. Contain water in a temporary trapping device. 102 Agreement No. 7526 Liquid Waste Management WM-10 WM-10 L IQUID W ASTE M ANAGEMENT This BMP includes procedures to prevent pollutant s related to non-hazardous liquid wastes from entering storm drains or receiving waters. Liquid wastes include drilling slurries, drilling fluids, wastewater that is free from grease and oil, dredgings, and other non-storm water liquid discharges not covered by separate permits. This BMP does not apply to the following: Dewatering operations (See NS-2) Solid wastes (See WM-5) Hazardous wastes (See WM-6) Concrete slurries (See WM-8) Liquid wastes covered by specific laws or permits Non-storm water discharges permitted by any Caltrans NPDES permit unless Caltrans determines that the discharge contains pollutants Applications All construction sites where liquid wastes are generated Key Points Capture all liquid wastes that have the potential to impact water entering the storm drain system. Use temporary dikes or berms to direct surface flow of liquid wastes to a containment structure or device. If liquid waste contains sediment, capture and treat the fl ow to remove sediment or capture in a containment structure to allow sediment to settle. Contain liquid wastes in a controlled area that is structurally sound, leak-free, and provides sufficient storage for the anticipated volume. Appropriate stru ctures include holding pits, sediment basins, roll-off bins, and portable tanks. Locate the containment structure such that accidental releases do not discharge to storm drains or receiving waters or threaten health or safety. Some liquid wastes may require testing and certification that they are non-hazardous before an appropriate disposal method is selected. Liquid waste may need to be treated to remove sediment or other pollutants prior to disposal. Typical liquid waste dis posal requires Dewatering (NS-2) with disposal of resulting solids per Solid Waste Management (WM- 5) or Standard Specification Section 7-1.13, “Disposal of Material Outside the Highway Right-of-Way.” Frequently inspect liquid waste containment areas and capturing devices for damage. Repair as needed. Preventive Measures and Troubleshooting Guide Field Condition:Common solutions are: Construct a temporary Sediment Trap (SC-3) and allow Liquid waste is sediment- laden. sediment to settle. Properly dispose of liquid waste. Capture flows by using temporary dikes or berms to intercept Liquid waste discharge is uncontrolled. flows and direct them to a containment device. 103 Agreement No. 7526 Notes PART IV: NOTES D ISTRICT C ONSTRUCTION S TORM W ATER C OORDINATORS 1Kirk Carrington(530) 582-9129 2Ted Schultz(530) 225-4640 3Kirk Carrington(530) 582-9129 4Frank Gorham(510) 286-5185 5Pete Riegelhuth(805) 549-3661 6Raafat Shehata(559) 488-4284 Sheri West(661) 395-2795 7James Burt(213) 897-1960 8Walt Griffith(909) 232-6496 9Richard Epler(209) 786-2932 10Richard Epler(209) 786-2932 11Michael Kolbenschlag(858) 467-4080 12Mark Doroudian(949) 724-2834 C ALTRANS H EADQUARTERS E NVIRONMENTAL W EBSITE www.dot.ca.gov/hq/env/stormwater/index.htm C OMMENTS A ND Q UESTIONS Please fax comments, questions, or concerns regard ing this manual or other BMP news to 714-567-2780. 104 Agreement No. 7526 EXHIBIT B Plans Agreement No. 7526 True North Compliance Services, Inc.
