These activities are the responsibility of the project sponsor. Repair. Repair is considered to entail those activities of a routine nature that maintain the project in a well kept condition. Replacement. Replacement covers those activities taken when a worn-out element or portion thereof is replaced. C. Rehabilitation. Rehabilitation refers to a set of 41 KA activities as necessary to bring a deteriorated project back to its original condition. CHAPTER 2 DESCRIPTION OF THE PROJECT Authorization. A Final Detailed Project Report was prepared by the USACE, dated April 1996, in response to a request for Federal assistance for shore protection by the City of Carlsbad, dated December 7, 1994. The study was undertaken by the U.S. Army Corps of Engineers Continuing Authority Program, pursuant to Section 103 of the of the River and Harbor Act of 1962 (Public Law 87-874), as amended, to investigate the feasibility and economic justification for protecting Carlsbad Boulevard located between the intake and outlet jetties of Agua Hedionda Lagoon. Description of the Project. The project site is located along a 3,580-foot segment (Station 20+00 to Station 55+80) of the shoreline west of Agua Hedionda Lagoon within the City of Carlsbad. The area is located about 3 miles downcoast (south) of Oceanside, California and 20 miles upcoast (north) of La Jolla, California. The site is within the Oceanside Littoral Cell. Typically, the coastline in this area of the City may be described as a very narrow beach (lagoon spit) fronted by discontinuous rounded cobble and gravel berms. Periodic hydraulic dredging of Agua Hedionda Lagoon by the San Diego Gas & Electric Company provides beach nourishment fill (primarily poorly graded fine sand with shell fragments) in the immediate vicinity of the project site. Seasonal high tides, waves, and wind erode the shoreline with regular frequency to the extent that existing improvements along the low lying Carlsbad Boulevard may be impacted by extreme coastal events. Extreme coastal events can overtop the roadway and cause damage to improvements. In order to protect improvements and keep Carlsbad Boulevard open to traffic year round, the subject shoreline protection has been constructed. Project Data Sheets and Maps. Project Data Sheets for the Carlsbad Boulevard Shore Protection project are included in Appendix B. These data sheets consist of an information page and the "as-built" drawings. These sheets furnish general 14 information about the date of completion of construction and locations of the seawall. Additional information, such as a location plan for the project, can be obtained from the "as- built" drawings. 4 PART II - OPERATION AND MAINTENANCE CHAPTER 3 GENERAL 1. Definitions. Special terms used in this manual are: STORM SEASON. Refers to the period of 15 October through 15 April. EMERGENCY STORM CONDITIONS. Refers to periods during which coastal storm conditions create waves which can erode the shoreline and allow for run-up on or over the seawall. C. SUPERINTENDENT. Refers to the City of Carlsbad official responsible for the development and functioning of the operation and maintenance organization. CORPS OF ENGINEERS. Refers to the Department of the Army, Corps of Engineers, Los Angeles District. DISTRICT ENGINEER. Refers to the District Engineer for the Corps of Engineers. CONSTRUCTION-OPERATIONS DIVISION. Refers to the Construction-Operations Division of the Corps of Engineers. ENGINEERING DIVISION. Refers to the Engineering Division of the Corps of Engineers. MLLW. All elevations refer to Mean Lower Low Water (MLLW) datum. SEAWALL. All structural elements of the subject shore protection system including inclined rock revetments, vertical retaining walls, and access ramps. 2. Reference Drawings. Drawings in this manual refer to the "as-built" drawings which are included in Appendix B. 3. Organizations responsible for Operation and Maintenance. The City of Carlsbad and the Corps of Engineers, Los Angeles District, are separately required to maintain organizations capable of adequately operating and maintaining the project units for shore protection control. The City shall appoint an official (referred to as "Superintendent") who shall be responsible for the development and proper functioning of that City's operation and maintenance organization. Personnel of the Construction- 5 Operations Division and the Engineering Division will be the Corps of Engineers' operations and maintenance organization. 4. Assistance to be Furnished by the District Engineer. The District Engineer (DE) shall: Furnish to the Superintendent "as-built" drawings of the seawall improvements, at the time they are transferred to the City for operation and maintenance. Make prior determination that any proposed encroachment, improvement, excavation, or construction within the rights-of- way, or alteration of the seawall works, will not adversely affect the functioning of the protective facilities; and furnish the Superintendent with a written approval. C. Assist the Superintendent, within regulatory constraints, in the performance of his/her duties in ascertaining storm development having shore erosion potential, assembling erosion-fighting forces and material, and initiating and carrying out erosion-fighting operations. 5. Responsibilities of the Superintendent. The general duties of the Superintendent include the following: Inspection. Inspection shall be made by the Superintendent after the end of the storm season in April or May of each year, immediately following each major high wave period, and at such intermediate times as may be necessary to ensure the best possible care of the project. Immediate steps shall be taken to correct dangerous conditions disclosed by such inspections. Maintenance. The Superintendent shall provide, at all times, such maintenance as may be required to ensure serviceability of the structures in time of high waves. Full responsibility for making repairs and the methods used is placed on the Superintendent, the Corps of Engineers will be available for advice and consultation. Regular maintenance repair measures shall be accomplished during the appropriate season as scheduled by the Superintendent. Repairs shall be made using standard engineering practices, to line and grade, and similar details shown on "as-built" drawings. No change or alteration shall be made to any feature of the erosion-control improvement without prior determination by the DE that such alterations will not a adversely affect the stability and functioning of the protective facilities. Plans and specifications of all changes or alterations that are proposed by the Superintendent shall be submitted to the DE for evaluation and approval before implementing the work. C. Reviewing Applications. Requests for temporary or permanent modification of seawall improvements must first be submitted to Superintendent, before a permit from the DE can be issued approving the modification. These applications will be reviewed by the Superintendent and then sent to the DE for consideration before any application is approved for a permit. Each application that is reviewed by the DE will be adequately evaluated in order to determine whether any modification will adversely affect the ability, safety, or functioning of the seawall. When such an evaluation by the DE has determined that approval can be given, the conditions which must be adhered to will be incorporated with the permit. Only at this time should the DE issue the legal document for the modification. Executed copies, in triplicate, of permit as issued, shall be furnished to the Superintendent. The Superintendent will enforce the conditions as set forth in the issued legal document, and will report immediately to the DE any uncorrected violations. After completion of the work, notice of satisfactory completion shall be furnished to the DE. The DE normally issues two types of permits: Permits for Rights-of-Entry to the Project Rights- of-Way. Adequate consideration by the CE is necessary to determine whether a temporary use of the rights-of-way will adversely affect the safety and functioning of the project structures, or the maintenance operations. Permits for Construction Within Project Rights-of- Most of the applications for use of Project Rights-of-Way consist of permanent construction alterations under, over, or into existing seawall improvements. Before a permit can be issued approving a project of this nature, a review of the application must be made. All work must be performed using standard engineering practices with plans and specifications reviewed and approved by the DE. Excavation Restrictions. Excavation is prohibited within the limits of the permanent rights-of-way, except as may be required to maintain the functional purpose of the project. d. Coordination of Local Activities. The Superintendent will, during periods of high waves, coordinate the functions and activities of all agencies, both public and private, that are 7 connected with the protective works. In order that police protection may be provided, the Superintendent shall make necessary arrangements with local law enforcement agencies. The Superintendent also arranges with utility companies and local agencies for the development of a coordinated erosion-fighting program, and files an outline of this program with the DE. e. Training of Key Personnel. Key personnel shall be trained so that regular maintenance work may be performed efficiently and to ensure that unexpected problems related to high waves may be handled in an expeditious and orderly manner. f. Semiannual O&M Reports. The Semiannual O&M Reports (See Appendix B), which are submitted in two (2) phases (the spring phase and the fall phase), will indicate: (1) the maintenance requirements of the project units at the end of the storm season, and (2) the readiness of these units, after summer maintenance, to accommodate high waves. The two phases of the Semiannual O&M Reports will give a progressive picture of the operation and maintenance of the project units for the year from 15 October to 15 October (from the start of one storm season to the end in the following year). Semiannual O&M reports will present a statement of: The physical condition of the protective works as summarized from the logs of inspection. Performance of the protective works during high waves during the period. Prosecutions for encroachment or trespassing, vehicular accidents affecting the seawall, and vandalism. Permits issued for rights-of-entry or use of rights-of-way. Permits issued for improvements or construction within the seawall improvement rights-of-way. Maintenance measures taken: nature, date of construction, date of removal of temporary repairs, and date of permanent repairs. Fiscal statement of cost of maintenance and operation for the period. g. Special O&M Reports. Special O&M Reports that accompany the Semiannual Report (spring phase only) are necessary only as a 8 result of extreme events such as high waves or unusual damage from storms, earthquakes or other causes. h. Transmittal. Original copies of Special O&M Reports should be made to the Department of the Army, Los Angeles District, Operations Branch *(213)452_3385* (as a follow up to immediate telephone information) within one week after the extreme event or within one week after the occurrence of damage not susceptible to temporary repairs. I. Time of Submittal. Except for Special O&M Reports, Semiannual O&M Reports on inspection, operation, and maintenance of project units are submitted semiannually (spring - on or before 1 June and fall - on or before 1 December) to the DE of the Corps of Engineers, Los Angeles District, ATTN: Operations Branch. A suggested form for submission of the Semiannual Report is enclosed as Appendix A, in this manual. Files and Records. The Superintendent shall maintain a file of reports, records, and drawings concerning the project works, readily available at all times to the DE. Check Lists. The check lists (see Appendix A) included in this manual are to be explicitly followed in each inspection to ensure that no features of the protective system are overlooked. Check lists shall be printed in conformity to those shown in Appendix A. A copy of the inspector's original field notes, as recorded on the check list, shall be transmitted to the DE immediately following each inspection. 6. Condition Survey Report. A condition survey of the seawall improvements may be made periodically by the Corps of Engineers, Los Angeles District, and the Superintendent shall be notified of any deficiency immediately after completion of the survey. The survey serves a twofold purpose: (a) to ascertain the actual condition of the seawall improvements and to note any deficiency, damage or malfunction of any part, and (b) to ascertain that all the repairs and improvements have been carried out by the local interests lAW their obligations. 4 PI 4 CHAPTER 4 OPERATION PROGRAM AND EMERGENCY OPERATIONS 1. General. The operation program, which includes storm emergency procedures, is in three phases: (a) prestorm phase; (b) storm phase; and (c) poststorm phase. Each of these phases include varying degrees of mobilization or demobilization, patrolling (including operation and maintenance), and reporting. Pertinent information on these phases is given in the following paragraphs: a. Prestorm Phase. The prestorm phase occurs whenever the National Weather Service forecasts large waves of more than 10 feet in height. The major operations during this phase include the following: Mobilization. Only such mobilization to perform the operations under the prestorm phase. Patrolling (including maintenance). During the prestorm phase, the completed seawall improvements should be patrolled to determine their readiness to accommodate large waves. The responsibility of the patrols should include but not be limited to the following: Readying Equipment and Material. Equipment and material shall be in a readied condition for use at locations where trouble may occur. Reporting. For the prestorm phase, no written reports are required for submittal to the District Engineer, Department of the Army, Los Angeles. However, such internal reports are suggested that would be helpful if storm waves increased to the point at which a storm report would be required. b. Storm phase. The storm phase occurs when large waves reach the seawall and overtopping occurs. The major operations during this phase include the following: Mobilization. Full mobilization is required. Patrolling (including maintenance). During the storm phase, patrolling of the completed project shall be continuous and comprehensive. The responsibility of the patrols shall include but not be limited to the following: (a) Photographing Damage. Photographs should be made of locations where overtopping and wave damage is occurring 10 or has occurred, where such photographs would help in making maintenance determinations. (b) Removing Debris. All debris accumulations that would reduce seawall function should be removed. (c) Observing and Controlling Other Conditions. Any condition endangering any other structure (i.e., adjacent jetties or street improvements) should be corrected. C. Poststorm Phase. The poststorm phase begins after storm waves have reduced to less than 10 feet in height. The major operation during this phase ends after storm waves at all the major operations indicated in the following subparagraphs have been completed. Demobilization. Some demobilization is satisfactory during this phase. However, full demobilization should be delayed until the operations under this poststorm phase have been completed. Patrolling (including maintenance). During the poststorm phase, the completed units should be rapidly and completely patrolled. The responsibility of the patrols should include the following: Locating. Recording. and Photographing Damage. All damaged seawall improvements should be located, recorded, and photographed. Checking Accumulation of Debris. The accumulation of debris adjacent to the seawall should be checked to ascertain whether or not it has reached the point where removal should be done. (C) Initiating Repairs. Applicable temporary or permanent repair of damaged seawall improvements should be initiated. (d) Inventorying Equipment and Materials. Equipment and materials should be inventoried and made ready for subsequent storm waves. (e) Reporting. For the poststorm phase, no written reports are required for submittal to the DE, U.S. Army Engineer District, Los Angeles. However, a brief narrative statement pertaining to general functioning of the seawall improvement, condition of the works, and actions for remedying 11 any defects would be helpful, particularly in the event a storm report or a Special O&M Report is required. 2. Emergency Operations. The City of Carlsbad will present the emergency operation plans that cover preparations for and responses to project emergency conditions. The Superintendent will provide an outline of emergency operation records to be maintained and available for inspection. a. The emergency operation plans should cover, but not be 8 limited to, such items as: Chain of responsibility. Emergency communications network including redundancies (internal and external). Local emergency response assistance such as fire, police, medical, and Red Cross. State and Federal emergency response agencies. b. The Superintendent shall present the emergency operation plans to: Chief of Emergency Management Branch (CESPL-CO-E), Los Angeles District, U.S. Army Corps of Engineers, P.O. Box 532711, Los Angeles, California 90053-2325, telephone: (213) 452-3440. 3. Notification of Distress. The Superintendent will immediately report to the Corps of Engineers of conditions that demonstrate evidence of distress or that could result in a potential hazard at the project. Initial reporting should be via telephone with a follow-up written summary with appropriate photographs. a. Typical evidence of distress to be reported is as follows: Significant damage to the structure integrity as a result of significant wave event, seismic event, or vehicle impact. Any other indications of distress or potential failure that could inhibit the operation of the project or endanger life and property. b. The Superintendent shall contact: Chief of Emergency Management Branch (CESPL-CO-E), Los Angeles District, U.S. Army 12 Corps of Engineers, P.O. Box 532711, Los Angeles, California 90053-2325, telephone: (213) 452-3440. 13 CHAPTER 5 MONITORING PROGRAM General. The Monitoring Program consists of periodic inspections and event inspections. The purpose of the Monitoring Program is to provide documentation of the condition of the -01 seawall structure and recommendations for necessary repairs. The inspections should provide detailed information as to the nature, location, and extent of any damage and recommended repairs. If necessary, the inspections should also recommend additional field data required for defining the damage or for the preparation of a repair contract. Inspection Procedures. Periodic inspections of the seawall structure shall be conducted annually by an inspection team consisting of individuals with appropriate specialized knowledge in structural, geotechnical, and coastal design to document changes in the seawall structure and to determine maintenance measures required. These inspections should be made after the end of the storm season in April or May of each year, so that the damages from storm waves, if any, can be detected. Event inspections shall be made after major storm events, major earthquakes, tsunamis, and vehicle impact. During each inspection, items requiring maintenance shall be identified in detail and described on plans of the structure. The inspection results and the latest monitoring data should be evaluated to provide information about the condition of the structure. The data may identify potential problem areas before they contribute to major structural problems. Pre-inspection Tasks. The first step in an effective inspection is for the inspection team to meet to review the Operations and Maintenance Manual, recent inspection reports, and previous video records and photographs of the structure. At this and any subsequent meetings, an inspection check list should be developed and responsibilities for each inspection task assigned. Then, a complete equipment check list must be prepared and responsibility for acquiring the equipment delegated. A check list is prepared for each inspection task. Proper equipment and materials are required to perform the inspections. Equipment and materials necessary for use in the field include: waterproof cameras, films, tape measures, hand levels, spray paint, half-tone annotated structural photo plans, check list, tidal and wave information, stakes, and markers. C. Prior to actual inspection, construction as-built drawings should be obtained and working sheets prepared. Station 14 locations and permanent survey monument locations should be superimposed on these sheets. If appropriate, typical cross sections and notes on structure dimensions may be superimposed on these sheets as well. They should be assembled in a station-to- station order and copies distributed to all inspection team members. It is important that all inspection results shall be recorded on these sheets, so that they can then be assembled easily into a single, comprehensive condition drawing of inspection findings. The collected findings of all inspections will be transferred to one set of sheets and this set will be included in the inspection report. 4 3. Periodic Inspections. The periodic inspection consists of a walk along of the seawall structure. The walk along shall be accomplished at low tide. The walk shall include the structure and the immediate areas, looking for indication of problems nearby which may affect the integrity of the seawall structure. The following procedures will be conducted: Stationing the Structure. The structure should be stationed for reference during the inspection. Stationing may be accomplished by using a measuring tape with respect to known monuments, or simply starting at the beginning of the seawall and taping the complete length. Accuracy for stationing is not critical, as long as deviation is within 1 foot every 100 feet measured. If possible, attempt to station every 100 or 200 feet. The stations themselves shall be marked with a visible lumber crayon (keel marker) on the concrete sidewalk surface. Visual Inspection. After the stationing has been accomplished, a visual inspection of the structure shall be conducted. The visual inspection shall be performed chiefly by the structural, geotechnical, and coastal engineers. If a problem area presents itself at a station, make a note of the station and describe the problem. Photographs and video records, which are good records of existing conditions, should be identified (date, structure, sand level, station, and direction of camera [i.e. looking North]). The inspection team will check: Vertical Seawall. Close visual inspection shall be made for damages caused by current, debris, loss of sand, and wave action and for indications of structural failure due to corrosion and wear. When failure or misalignment is observed, the seawall structure shall be examined minutely to determine cause of failure. Rock Revetment. Close visual inspection of rock revetment and filter fabric shall be made for damages caused by 15 current, debris, loss of sand, and wave action and for indications of structural failure due to corrosion and wear. When failure or misalignment is observed, rock revetment shall be examined minutely to determine cause of failure.. Buried Toe Stone. Inspect to identify exposed toe stone and filter fabric which may be uncovered by storm waves and shoreline erosion and damage due to normal deterioration and wear. Sidewalks. Railing. Access Ramps and Stairs. Inspect to determine the need for repairs to sidewalks, railing access ramps, and stairs. Handrails and steel posts shall be inspected for signs of corrosion. Planters, Drain lines. Ceramic Tiles, and Lifeguard Towers. Amenities to the seawall such as planters, Drain lines, ceramic tiles, and lifeguard towers shall be inspected at the City of Carlsbad discretion and need not be included in the O&M reports. C. Discussion of Walk Along. Following the walk along and visual inspection, the inspection team will conduct a group discussion about what has been seen and recorded. Past problem areas shall be brought up to date (better, worse, no change), and all potential new problem areas will be identified. Perhaps theories to the reason of the problems will be discussed and recorded. d. Condition of Beach Sand. The beach sand fronting the seawall and blown/overwashed sand behind the seawall should be monitored by visual and survey methods. 4. Event Inspections. (Major Storm, Earthquake, etc.) The inspection tasks for event inspections are geared for events such as a major storm, a major earthquake, or any other event which may lead to a failure of part or all of the structure. This type of inspection generally will be an emergency inspection. The event inspection will require the pre-inspection tasks addressed in Paragraph 2 of this chapter. The inspection will be comprised of a walk along at low water. A follow-up periodic inspection may be scheduled if the event inspection warrants one. a. Event Inspection Walk Along. The inspection should be scheduled at low water to maximize the visual observations of the seawall structure. The procedures discussed in Paragraph 3: Periodic Inspections will be conducted. These procedures are (1) Stationing the Structure, (2) Visual Inspection, and (3) Discussion of Walk Along. 16 CHAPTER 6 INSPECTION AND MAINTENANCE CRITERIA TO PROVIDE A BASIS FOR RECOMMENDING REPAIRS General. These criteria provide the general and specific design considerations related to the seawall system to furnish lff protection as designed. Visual Inspection and Reporting. Visual inspection and reporting of all conditions is the main method of supplying information for a Preventative Maintenance Program. Conscientious visual inspection furnishes evidence of the proper functioning of the seawall system. The criteria in this section will provide a basis for determining the extent of investigation and repair needed to correct defects and restore the facility to full design capacity. Preventative maintenance established will be used at other locations where the same situation exists. Modification of Seawall Improvements. Modifications including repairs and/or alterations of seawall improvements shall be submitted with plans, specifications, and design considerations (including applicable design calculations) to Corps of Engineers using the existing applications procedure modified as stated under Part II, Chapter 3, Section 5: Responsibilities of the Superintendent. Seawall Design. Seawall design involves many specialized engineering sciences to provide shoreline protection over many years. Seawall improvements require regular replacements, care and attention to fulfill their design life. The remainder of this Chapter presents some of the design considerations for the seawall improvements. The design considerations should aid inspections and determining the implications of the conditions observed for recommending adequate preventative and/or restorative maintenance. General Design Concept. The general design concept is to provide a stable and reliable seawall to protect Carlsbad Boulevard, exposed and buried improvements, and people during high wave conditions. A summary of the seawall design is presented in the document entitled, "Detailed Project Report, Section 103, Carlsbad Boulevard, Carlsbad, San Diego County, California, Volumes I and II," prepared by the Corps of Engineers, Los Angeles District, dated April 1996. Concrete Work. All concrete work shall be checked for evidence of deterioration, structural cracking, or displacement. Defective concrete should be replaced or repaired before there is 17 appreciable loss of strength in the structure. Cracking in concrete structures should be monitored. Minor shrinkage and temperature cracking will normally take place in most structures but continued development of crack patterns and increase in size of cracks is evidence of distress in the structure. The cause of excessive cracking must be investigated before the stability of the structure is endangered. Large cracks that will allow considerable water to penetrate the concrete cap of the seawall ( should be sealed to prevent further migration of the crack and also to prevent damage to the steel reinforcement and sheet piling. Expansion joints are provided at regular intervals. 7. Rock Revetments. Rock revetments should be inspected for evidence of displacement and deterioration of the stone. The revetments have been designed with stone of sufficient size and quality to minimize the displacements and deterioration. The revetment should also be inspected for evidence of backfill piping through the under layers if possible. The design incorporates a filter fabric below the stone to minimize the piping. If the displacement or deterioration of the stone is such that it exposes the filter fabric, repairs should be undertaken to cover the filter fabric with stone. B. Toe Stone. Toe Stone (1,500-pound stone) has been used along the seawall (starting at +6 feet MLLW) to preserve the shoreside embedment of the sheet piling. The top of the Toe Stone, if exposed, should be inspected to verify that the elevation is no more than 1 foot below the design elevation. If it is, repairs should be undertaken to add Toe Stone to the design elevation. The Toe Stone should be inspected for piping similar to the rock revetments. Toe Stone has also been installed at the base of stairways and access ramps. Steel Sheet Piles. The primary structural component of the seawall is high strength ASTM A690 mariner steel sheet piling. The specified sheet piling is designed to resist corrosion and be protected from direct wave impact by Toe Stone and a reinforced concrete cap. Handrails. Handrails are provided for safety of people walking along the wall, stairways, and ramps. Handrails are made of anodized aluminum and should be repaired if damaged. Steel Posts. Steel posts at the heads of ramps are provided as removable vehicle barriers. Other Amenities. Amenities such as drinking fountains, planters, benches, lifeguard towers, and public artwork have been 18 included in the design of the seawall but are not included in the scope of this manual. Rights-of-Way Conditions. Areas adjacent to seawall improvement shall be clear for the access necessary to comply with all operation and maintenance requirements. Seawall improvements are designed for specific loading conditions. Abnormal loading conditions on any seawall should be precluded. Debris Removal. Whenever the accumulation of debris adjacent to the seawall is significant, the debris must be removed. To ensure early detection and timely removal of any excess accumulation, an estimate as to the amount of debris should be noted during each periodic inspection. The results of these estimates should be noted in the appropriate Operation and Maintenance Report. Maintenance of Signs. Signs shall be maintained intact. 19 CHAPTER 7 PERIODIC INSPECTION REPORT WITH RECOMMENDED REPAIR Scope. Concise standard terminology shall be used to report the recommended repairs. The terminology shall be specific rather than general. The listed typical repairs are not inclusive and are not intended to represent either the condition to be corrected or that the typical repair is for only one type of corrective action. Repairs. Repairs include preventative maintenance. Scheduling. The Maintenance Repair Program, which includes all corrective action necessary to provide effective shoreline protection during every storm season, shall be scheduled at a rate to maintain all seawall improvements with an optimum protection capability. The program shall not fluctuate from year to year, but rather will be expanded with the increasing age and extent of the maintained facilities. Frequency. Frequency of permanent repairs will be on an as-needed basis. Temporary work and preventative maintenance will be a usual and continuing seasonal requirement. Basis. Basis for repairs is the inspection reports, the investigation program, and the guidance in this manual, supplemented by planned and scheduled repairs. Standards. Standards for repairs are the engineering practice used for the latest similar approved construction. Approval of proposed permanent methods of construction will be furnished through the regular application procedure by the Los Angeles District of the Corps of Engineers. Any requests for modification of seawall improvements, due to repair work, need to be submitted as soon as possible after damage has been incurred. Limitations. Temporary repair work during the storm season from 15 October through 15 April shall be replaced with permanent repairs during the subsequent calm season. Temporary Work. Temporary work will be used to expedite the protection of facilities to ensure that the seawall improvements will perform as designed. The various types of temporary work will be reported and the more successful types, based on experience record, will be used for the applicable temporary work. Permanent Work. Permanent work will be used to replace I 20 temporary work and/or reduce annual maintenance. For permanent work within the capabilities of the repair organization, the work will be scheduled and budgeted annually. Major repairs will be constructed similarly to new erosion-control construction. 10. Debris Removal. Debris removal is a regularly scheduled routine requirement and part of all repairs as well as inspection preparation. 11. Concrete Repairs. Concrete repairs shall include the following: Sealing cracked concrete (where cracks permit migration of fines) by concrete sawing, chipping, cleaning, and dry- packing. Resealing expansion joint with bituminous material. 12. Rock Revetment Repairs. Rock revetment repairs for the reporting feature include the following: Readjusting dislodged rock. Replacement of fractured rock. 13. Toe Stone Repair. Toe Stone repairs for the seawall will include the following: Replacement up to design elevations. Readjusting dislodged stones. C. Replacing fractured stones. 14. Handrail Repairs. Handrails should be repaired by replacement with new sections of the handrail. 15. Rights-of-Way Maintenance. Faulty rights-of-way maintenance can impair seawall protection as much as other faulty seawall improvements. Rights-of-way maintenance or correction include the following: Establishment of adequate width of the access roadways. Establishment of continuous access roadways with access to streets at bridges or turnarounds or under bridge access ways. C. Removal of encroachments. 21 A Establishment of controlled access for minimum seawall rights-of-way. Restoration of security methods on access ways. 22 1 PART III - APPENDICES 23 APPENDIX A EXLE OF SEMIANNUAL REPORT MW CHECK LISTS Check List for Project Inspection See Chapter 5: Monitoring Program for the description of items in the following check list.

ARTICLE IV - CREDIT FOR VALUE OF LANDS, RELOCATIONS, AND DISPOSAL AREAS The Non-Federal Sponsor shall receive credit toward its share of total project costs for the value of the lands, easements, rights-of-way, and suitable borrow and dredged or excavated material disposal areas that the Non-Federal Sponsor must provide pursuant to Article III of this Agreement, and for the value of the relocations that the Non-Federal Sponsor must perform or for which it must ensure performance pursuant to Article III of this Agreement. However, the Non-Federal Sponsor shall not receive credit for the value of any lands, easements, rights-of-way, relocations, or borrow and dredged or excavated material disposal areas that have been provided previously as an item of cooperation for another Federal project. The Non-Federal Sponsor also shall not receive credit for the value of lands, easements, rights-of-way, relocations, or borrow and dredged or excavated material disposal areas to the extent that such items are provided using Federal funds unless the Federal granting agency verifies in writing that such credit is expressly authorized by statute. For the sole purpose of affording credit in accordance with this Agreement, the value of lands, easements, and rights- of-way, including those necessary for relocations, borrow materials, and dredged or excavated material disposal, shall be the fair market value of the real property interests, plus certain incidental costs of acquiring those interests, as determined in accordance with the provisions of this paragraph. 1. Date of Valuation. The fair market value of lands, easements, or rights-of-way owned by the Non-Federal Sponsor on [:] the effective date of this Agreement shall be the fair market value of such real property interests as of the date the Non- Federal Sponsor provides the Government with authorization for entry thereto. The fair market value of lands, easements, or rights-of-way acquired by the Non-Federal Sponsor after the effective date of this Agreement shall be the fair market value of such real property interests at the time the interests are acquired. 2. General Valuation Procedure. Except as provided in paragraph B.3. of this Article, the fair market value of lands, easements, or rights-of-way shall be determined in accordance with paragraph B.2.a. of this Article, unless thereafter a different amount is determined to represent fair market value in accordance with paragraph B.2.b. of this Article. a. The Non-Federal Sponsor shall obtain, for each real property interest, an appraisal that is prepared by a qualified appraiser who is acceptable to the Non-Federal Sponsor and the Government. The appraisal must be prepared in accordance with the applicable rules of just compensation, as specified by the Government. The fair market value shall be the amount set forth in the Non-Federal Sponsor's appraisal, if such appraisal is approved by the Government. In the event the Government does not approve the Non-Federal Sponsor's appraisal, the Non-Federal Sponsor may obtain a second appraisal, and the fair market value shall be the amount set forth in the Non-Federal Sponsor's second appraisal, if such appraisal is approved by the Government. In the event the Government does not approve the Non-Federal Sponsor's second appraisal, or the Non-Federal Sponsor chooses not to obtain a second appraisal, the Government shall obtain an appraisal, and the fair market value shall be the amount set forth in the Government's appraisal, if such appraisal is approved by the Non-Federal Sponsor. In the event the Non- Federal Sponsor does not approve the Government's appraisal, the Government, after consultation with the Non-Federal Sponsor, shall consider the Government's and the Non-Federal Sponsor's appraisals and determine an amount based thereon, which shall be deemed to be the fair market value. b. Where the amount paid or proposed to be paid by the Non-Federal Sponsor for the real property interest exceeds the amount determined pursuant to paragraph B.2.a. of this Article, the Government, at the request of the Non-Federal Sponsor, shall consider all factors relevant to determining fair market value and, in its sole discretion, after consultation with the Non-Federal Sponsor, may approve in writing an amount greater than the amount determined pursuant to paragraph B.2.a. of this Article, but not to exceed the amount actually paid or proposed to be paid. If the Government approves such an amount, the fair market value shall be the lesser of the approved amount or the amount paid by the Non-Federal Sponsor, but no less than the amount determined pursuant to paragraph B.2.a. of this Article. 3. Eminent Domain Valuation Procedure. For lands, easements, or rights-of-way acquired by eminent domain proceedings instituted after the effective date of this Agreement, the Non-Federal Sponsor shall, prior to instituting such proceedings, submit to the Government notification in writing of its intent to institute such proceedings and an appraisal of the specific real property interests to be acquired in such proceedings. The Government shall have 60 days after receipt of such a notice and appraisal within which to review the appraisal, if not previously approved by the Government in writing. If the Government previously has approved the appraisal in writing, or if the Government provides written approval of, or takes no action on, the appraisal within such 60- day period, the Non-Federal Sponsor shall use the amount set forth in such appraisal as the estimate of just compensation for the purpose of instituting the eminent domain proceeding. If the Government provides written disapproval of the appraisal, including the reasons for disapproval, within such 60-day period, the Government and the Non-Federal Sponsor shall consult in good faith to promptly resolve the issues or areas of disagreement that are identified in the Government's written disapproval. If, after such good faith consultation, the Government and the Non-Federal Sponsor agree as to an appropriate amount, then the Non-Federal Sponsor shall use that amount as the estimate of just compensation for the purpose of instituting the eminent domain proceeding. If, after such good faith consultation, the Government and the Non-Federal Sponsor cannot agree as to an appropriate amount, then the Non-Federal Sponsor may use the amount set forth in its appraisal as the estimate of just compensation for the purpose of instituting the eminent domain proceeding. For lands, easements, or rights-of-way acquired by eminent domain proceedings instituted in accordance with sub-paragraph B.3. of this Article, fair market value shall be either the amount of the court award for the real property interests taken, to the extent the Government determined such interests are required for the construction, operation, and maintenance of the Project, or the amount of any .stipulated settlement or portion thereof that the Government approves in writing. 4. Incidental Costs. For lands, easements, or rights- of-way acquired by the Non-Federal Sponsor within a five-year period preceding the effective date of this Agreement, or at any time- after the effective date of this Agreement, the value of the interest shall include the documented incidental costs of acquiring the interest, as determined by the Government, subject to an audit in accordance with Article X.C. of this Agreement to determine reasonableness, allocability, and allowability of.. costs.

C. After consultation with the Non-Federal Sponsor, the Government shall determine the value of relocations in accordance with the provisions of this paragraph. For a relocation other than a highway, the value shall be only that portion of relocation costs that the Government determines is necessary to provide a functionally equivalent facility, reduced by depreciation, as applicable, and by the salvage value of any removed items. For a relocation of a highway, the value shall be only that portion of relocation costs that would be necessary to accomplish the relocation in accordance with the design standard that the State of California would apply under similar conditions of geography and traffic load, reduced by the salvage value of any removed items. Relocation costs shall include, but not necessarily be limited to, actual costs of performing the relocation; planning, engineering and design costs; supervision and administration costs; and documented incidental costs associated with performance of the relocation, but shall not include any costs due to betterments, as determined by the Government, nor any additional cost of using new material when suitable used material is available.
