UlTG.08/18/87 1EPT.A TITLE: APPROVE CONSULTANT AGREEMENT FOR CITY OF CARLSBAD'S SAND SURVEY AND BEACH PROFILE DATA GATHER1 RECOMMENDED ACTION: Adopt Resolution No. 9&-(approving a consultant agreement with Tekmarine, Incorporated, for the City of Carlsbad's sand survey and beach profile data gathering program. ITEM EXPLANATION: On February 3, 1987, the City Council approved the Beach Erosion Committee's recommendation to resume the City of Carlsbad's sand survey and beach profile data gathering program. Since that time, the Beach Erosion Committee has met regularly for the purposes of formulating the program's scope of work, preparing requests for consult ant proposals, identifying potential oceanographic and coastal engineering firms, and soliciting and reviewing consultant proposals. The Committee convened on both July 24 and 27, 1987, and reviewed the consultants' detailed project proposal, received present at ions, and conducted interviews with the following oceanographic and coastal engineering firms selected by the Committee: Scripps Institute of Oceanography La Jolla, California Dr. Rienhard Flick Moffatt and Nichol Engineers, Incorporated Long Beach, California Dr. Craig H. Everts Tekmarine, Incorporated Pasadena, California Dr. Choule J. Sonu Following these interviews, the Beach Erosion Committee selected Tekmarine, Incorporated, as the firm to be recommended to the City Council to conduct the sand survey and beach profile data gathering program. The attached consultant agreement incorporates Tekmarine's detailed project proposal and will be performed on an annual, fiscal year basis. The consultant will immediately begin establishing the necessary coastal survey monumentations for the profile program. The beach profiles will be taken in October and April to correspond with the United States Army Corps of Engineers profile schedule taking place the entire length of the southern California coast. Dr. Choule Sonu and Tekmarine staff will be available on a consultant basis to discuss the findings of the semi-annual profiles, as well as, other coastal issues affecting Carlsbad's beaches. Page Two of Agenda Bill No. fFl,/-'X As previously indicated to the City Council in the Beach Erosion Committee's report of February 3, 1987, beach profiles and sand surveys along Carlsbad's beaches are critical to a better understanding and establishing the foundation for recommendations for beach erosion control measures. No survey data has been taken since late 1983. Gathering a data base is of particular importance given the timing of the Batiquitos Lagoon Enhancement Project, testing and eventual operation of the Oceanside Harbor Bypass project and assessing, over time, Carlsbad's net near- shore sand transport. FISCAL IMPACT: On February 3, 1987, the City Council approved the resumption of the Carlsbad sand survey and beach profile data gathering program. The Council authorized use of the Municipal Projects Department's miscellaneous consultants and professional services account No. 001-820-3130-2479 to fund the profile program, estimated to be approximately $20,000 per year. These funds have been appropriated in the 1987-88 fiscal budget in this account for the program. Tekmarine, Incorporated's lump sum, not-to- exceed cost to perform the sand survey and beach profile data gathering program for fiscal 1987-88 is $19,908. Staff recommends approval of the attached consultant agreement. EXHIBITS: 1.

As stated in the RFP, these specific tasks are part of an overall Sand Survey and Beach Profile Program aiming to achieve the following objectives: - Measurement and analysis of sand migration and retention by Carlsbad beaches of sand generated by the Oceanside Harbor Bypass Project. - Analysis and recommendations for placement and management of sand to be generated by the City of Carlsbad‘s future Batiquitos Lagoon Enhancement Pro j ec t . - Gather, assemble, analyze and report sand survey and beach profile data beneficial to the City of Carlsbad’s beaches in an effort to gen- erate historical data. - Respond to major coastal events and perform related coastal investiga- tive studies as required by the City of Carlsbad. 2.0 TBKMWlM QUALIFICATIONS 2.1 Relevant Project Experience Tekmarine, Inc. is expertly qualified to provide the services re- quested by the Committee by virtue of our recently completed and/or ongoing site-specific project experience. The most significant of these projects include the following: Nearshore Surveying in the San Diego Region (U.S.-Mexican Border to Dana Point) for the Coast of California Storm and Tidal Waves Study (CCSTWS) sponsored by the U. S. Army Corps of Engineers/Los Angeles District (USACOE/LAD)(April, 1986 - April, 1988). Coastal Engineering Services for the Batiquitos Lagoon Enhancement Project sponsored by the Port of Los Angeles and the City of Carlsbad (on-going). Review of Sediment Budget Methodology with Special Reference to the Oceanside Littoral Cell sponsored by the USACOE/LAD (completed June, 1987). In addition to these site-specific projects, Tekmarine is presently performing beach profile and analysis services for the County of Los Angeles to determine the optimum placement of beach fill material. Furthermore, we have provided numerous beach profiling programs in sup- port of island construction, shore protection monitoring and coastal facilities planning for major oil company clients in the Alaskan Beaufort Sea since 1980. Additional project experience in support of our ability to provide a broad range of coastal engineering consulting services includes the following: 2 .- Endicott Production Island - as the coastal engineering consultant for the first offshore oil production island in the Alaskan Beaufort Sea, Tekmarine developed, tested, and designed both soft and hard slope protection armor systems and subsequently provided construction in- spection services (including underwater inspection) and continues to provide slope protection performance monitoring services. Southern California Edison (SCE) Coastal Engineering and Oceanographic Consultant - since 1980 Tekmarine has provided consulting services to SCE. In this capacity Tekmarine has pioneered several techniques in evaluating the oceanographic influence of San Onofre Nuclear Generating Station effluents including satellite remote sensing of sea surface temperatures, aircraft mounted thermal infrared scanning, three-dimensional temperature mapping using a state-of-the-art towed thermistor chain, and numerical modeling of local currents and thermal plume interaction. Several important oceanographic discoveries have been made as a result of the on-going research effort. Santa Monica Pier Restoration - As the oceanographic consultant, Tekmarine provided a full range of oceanographic design criteria analysis, evaluated the impact of various breakwater alternatives on the littoral drift and local beaches, and developed special methodologies for computation of wave spectrum propagation from deep to shallow water. 2.2 Personnel Tekmarine employs a staff of seven professionals, all of which are trained in coastal and/or ocean engineering. Educational credentials of the employees includes two PhD’s, four MS degrees, and one BS degree. Three members of the staff are registered Professional Engineers in the state of California. Employee resumes are included in Appendix A. 3 . 2.3 Responsiveness Tekmarine is located in Pasadena, California, within commuting dis- tance of Carlsbad. Consequently, we shall be able to respond quickly for attendance at meetings and/or field services. Our ability to respond is further enhanced by the fact that our entire staff is trained in coastal and/or ocean engineering. Therefore, our roles are interchangeable and our ability to respond is not restricted should a key employee be indis- posed at a time of need. Furthermore, Tekmarine owns an extensive array of nearshore surveying equipment, including a trailerable survey vessel and two survey fathometers, making it possible to mobilize quickly for field surveys. 2.4 Partial List of Clients At the request of the Committee, we are pleased to include a partial list of our clientele in Table 2-1. 4 ...

Section 1) of the Sand Survey and Beach Profile Program. We believe that beach profiling supplemented with field reconnaissance, photography, and expert analysis is the principal means to accomplish the objectives of the Committee's program. We applaud the foresight of the City of Carlsbad to es- tablish a systematic data collection and archiving program, and offer the following comments and recommendations. 3.1 Data Acquisition Schedule of Beach Profiling Tekmarine concurs with the proposed schedule of semi-annual surveys in the months of April and October. Profiles obtained at this time of year will be representative of typical winter and summer profiles, respectively, and will coincide in time with the on-going COE surveys in the Carlsbad area. Also in regard to scheduling, it is emphasized that the time separation between the wading and boat surveys, as well as the overall time to complete the field survey should be kept to a minimum. In so doing, a "snapshot" of the beach profile can be obtained by minimizing the occurrence of naturally occurring profile changes throughout the sur- vey. Tekmarine has been performing nearshore surveys for the USACOWLAD since October, 1986, and is contracted to continue the task until April, 1988. One of the basis for our selection was our ability to perform the survey in a timely manner. The survey involves beach profiling at 57 stations between the U.S.-Mexican Border and Dana Point. We completed the 6 first field survey in 11 days, the second in 7 days, and the third in 11 days. In comparison, the previous contractor required one to two months to survey a comparable number of stations. Wading Surveys It is important to stress that the wading survey should be extended as far offshore as possible. Through our repeated survey experiences, we have discovered that the wading survey can be extended routinely to a water depth of about 3 m below mean lower low water (MLLW) without loss of data accuracy. Profiles extending to this depth would allow a detailed analysis of sand movement not only on the beach but also on the seabed over a considerable portion of the surf zone where the predominant sand movement is known to take place. The wading profiles are particularly well suited for tracking the longshore transport of the beach fill which will be placed south the Oceanside Earbor from the forthcoming bypassing operations, because they are inexpensive relative to boat surveys and can be implemented at short notice. Wading profiles alone were sufficient to perform real-time tracking of a sand wave migrating along the shoreline, as demonstrated in our recent 1985-86 study at San Onofre (Grove, Sonu and Dykstra, 1987). of Boat Surveys It is important that the deep-water profiles extend some distance beyond a 10-meter (30-ft) depth. This requirement stems from the fact that in the Oceanside littoral cell, in which Carlsbad is located, the offshore boundary of significant profile change is located at ap- proximately 10 m (Dolan et al., 1987; Tekmarine, 1987). Since the offshore boundary of the control volume used for sediment budget analysis should be located beyond this point, a 12 m (40-ft) depth is a suitable limit both in terms of the practicallity of the survey operations and the .- I analysis of sediment budget. Figure 3-1 shows examples of profile closure at depths near 10 meters in the Oceanside littoral cell. Beach Reconnaissance and Photography The texture of the beach, featuring sediment types and depositional forms (such as cusps, berms, aeolian deposits, debris lines, escarpments, backshore and coastal structures, installations and facilities, bluff faces, etc.), as well as surf zone dynamics (such as rip channels, breaking wave patterns, wave incidence angles, wave runup, etc.), can be highly useful information in understanding and interpreting the surveyed profile data. For this purpose, expert observation of the state of the beach and beach photography at each time of profile survey should be made part of the profile survey program. For this purpose, it makes sense that the survey program be conducted by trained coastal engineers. The photographs should not only record the profiles being surveyed, but also the intervening beach between the spaced profile stations. For the inter-station photography, the camera should be positioned at designated high ground locations and aimed in designated directions, so that the time-separated scenes may be compared. LEO Data Another important source of information on beach processes is the LEO (Littoral Environmental Observation) program data. The program con- sists of periodical recordings of observed waves, currents (longshore and rip currents), beach profiles, and sedimentary features by local person- nel (park rangers, etc.) which were initiated by the Corps of Engineers in the late 1960's in southern California and Lake Michigan. At Carlsbad, two stations were activated and the program was continued for two years in 1969 and 1970.

This example clearly bears out the presence of a longshore current reversal which is known to occur in the Oceanside littoral cell mainly during the summer months (June- . September), although the duration of the reversal and its intensity are known to vary from year to year. All this information is extremely valu- able for the understanding of local coastal processes, making the LEO program one of the most cost-effective and practical means of acquiring such information. Unfortunately, the LEO program has been discontinued since then, and we strongly recommend that the program be revived for the City of Carlsbad. The Corps of Engineers Los Angeles District is willing to help re-start the program (at a one-time fee of less than ap- proximately $2,000) which will include data analysis at the Coastal Engineering Research Center, as well. 3.2 Survey Data Analysis Data Processing The data analysis has two separate but related aspects: data processing and interpretation. The data processing is a procedure by which the raw field data is read, checked, tabulated and plotted into useful forms. This procedure can be handled by a special data base management technology currently in use at Tekmarine to process the Corps of Engineers nearshore survey data. This technology is illustrated in Figure 3-3. The programs BPAS (Beach Profile Analysis System) and ISRP (Interactive Survey Reduction Program) have been developed by the Coastal Engineering Research Center. Although these programs have the capabilities for quality-control checking of the raw data, we have added another tier of quality control with a highly efficient QA program. The BPAS and ISRP along with the Tekmarine QA program allow an extremely wide range of data manipulation capabilities embracing practically all 10 , Z 0 0 0 0 0. 0-w a Ly Z - Y I Y L h > -0 2 I- -0 0 n -w cn 00 0 0. 0 0 0 ( 0 2 0 s c3 -3 a 0 w I- 2 0 4i 0 QE QE 3 0 00 0 00 0 a a -a 0 0. 00 0 0 U -a =E 00 m -w LL z -a 7 ?4 I m 0 0 Hlnos 01 11 -- PROFILE & SHORELINE DATA BASE Y I31II,, I -Y x TEKMARINE QA DIAGNOSIS BPAS / ISRP TABULATION, PLOTTING, VOLUME, DIFFERENCES, CHANGES DBASE FIGURE 3-3.

An example of shoreline change and volume change result- ing from time-separated profiles along the southern California coast is shown in Figure 3-4. Data Interpretation/Sediment Budget The second aspect of data analysis, i.e. data interpretation, es- sentially boils down to constructing a sediment budget. Figure 3-5 shows a schematic illustration of the concept of sediment budget. The sediment budget analysis is a technique of quantifying all the inputs and outputs of sediment relative to a designated segment of the coast, called control volume, in reference to the various sources, pathways and sinks of sedi- ment which affect the littoral zone. By balancing these various elements, one seeks to identify specific processes which may be linked to the behavior of beach profiles at issue (i.e. either erosion or accretion) in that segment. A reliable sediment budget allows one to bring more scientific and quantitative judgements into the evaluation of the cause, the present status and the future trend of beach erosion. The procedure of constructing a sediment budget is not automatic, since there are usually more unknown variables than can be uniquely determined. The data on beach profiles plays an important role in reduc- ing the number of such unknowns and thereby enhancing the credibility of a constructed sediment budget. Additional important information will be. the knowledge of site-specific shoreline history, historical data (including air photos), and wave climate, among others. Still, the ability of an expert to carry out insightful reasoning based on his prior experience in sediment budget and beach processes will play a significant role. In a recent study performed for the Corps of Engineers Los Angeles District, Tekmarine (1987) conducted an extensive review of the current sediment budget methodology with special ref e r ence 13 e C 5 e f P 40: tl -eu 1 -10 4-m- , I 1 1 1 . . , r . . . . . , . . . 1_ -r-+-vm 1 3 126 384 530 670 1000 1280 leeo Won (Madcon Bo- to Dono Polnt) VOLUME CHANGE ABOVE MLLW (Apd 1B11-~ 1011) 50 40 30 20 10 n FIGURE 3-4.

Major findings resulting from this study, some of them startling in nature, can be used readily for con- structing a sediment budget for Carlsbad. Tekmarine has also acquired a detailed site-specific knowledge of both historical and current coastal processes along the Carlsbad shoreline through several local projects, including (1) repeated nearshore surveys (April and October 1986; April 1987; for USACOE/LAD), (2) a wave overwash and aeolian sediment transport study (1986 for USACOE/LAD), (3) sediment budget analyses (1986-87; for USACOE/LAD), and (4) its on-going project on the engineering of the tidal entrance at Batiquitos Lagoon and the beach nourishment for the City. Tekmarine engineers have undertaken at least a dozen ground reconnais- sance trips between south Oceanside and the entrance to Batiquitos Lagoon since April 1986. Data Base Coastal engineering is basically an empirical discipline, and its planning and design can only be as good as the data. We strongly feel that it is about time that the City of Carlsbad consolidate the informa- tion and data on its shoreline. At the least, the City should have a central information file which catalogues all the historical data, com- plete with annotations as to their usefulness, and whereabouts. The Corps of Engineers Los Angeles District has already performed type of task for the entire Oceanside littoral cell as part of the Coast of California Storm and Tidal Wave Study, so that the remaining work for the City of Carlsbad is to single out the part which relates to the City shoreline. The catalogued information should consist of historical bathymetric surveys, profile surveys, aerial photographs, ground photographs, hydrological' and hydraulic information, annotated bibliog- raphy, and the LEO data. this Additionally, a computerized data base may be constructed to con- solidate the past and future profile data into a form allowing ready and easy retrieval. As already shown in Figure 3-3, a generic data base 16 management program, DBASE, which stores the beach profile survey data in a versatile data base is already in use for the Corps of Engineers. Sharing a data base management system with the Corps of Engineers will facilitate data acquisition from the USACOE/LAD and the Coastal Engineering Research Center. By virtue of the on-going data management services for the Corps of Engineers, Tekmarine can provide a similar service to the City of Carlsbad without additional development work. 3.3 Consulting Services The need for unscheduled consulting services on shoreline problems exists for the City of Carlsbad. It is desirable that the consultants providing such services are located nearby, so that their physical presence can be realized at short notices. It is also desirable that the consultants represent the best expertise available locally in terms of the full spectrum of potentially required services which include under- standing the science of coastal sediment transport processes, performing engineering planning and design of major coastal facilities and erosion mitigation measures, experience in public presentation and court witness, and field survey and oceanographic monitoring expertise. Tekmarine has both the track record and resources to meet these requirements fully. We feel that Tekmarine can be particularly useful to the City by virtue of its insightful understanding of the local coastal processes, as evidenced by our on-going role as the coastal engineering consultants for the Batiquitos Lagoon Enhancement Project. Additionally, as shown in Figure 3-6, it took Tekmarine to derive a new and very important inter- pretation from the dredging data at Oceanside Harbor. Our interpretation determined that the maintenance dredging at Oceanside Harbor since 1965 should be viewed as two successive periods of distinct dredging rates (450,000 cylyear to 1971 and 293,000 cy/year after that), rather than one whole period with a single average dredging rate (300,650 17 .*-- - SL REY R. - 9-TH - 3RD - TY SON - WISCONSIN -WHITTERBY I NOURISHMENT VOLUME 1- MAJNTENANCE - r't i HARBOR II CONSTRUCTION -5 t- u) Q, F In (D v) t- c) co NOURISHMENT LOCATIONS YEAR 81 77 76 75 73 71 69 68 67 66 1965 T it:i::IDE Ill1 I Ill1 I I 0 v) W 1 : I I c 3 v) 2 0 FIGURE 3-6. Diagrams Showing Correlation Between the Dredging Rates at Oceanside Harbor and the Locations of Spoil Disposal. 18 .- cy/year). Our further investigation revealed that the significant drop in dredging rates at Oceanside Harbor since 1972 had to do with the change of the dredge disposal locations further away from the harbor beginning in 1972. Surprisingly, the change in the disposal location in- volved a distance of only less than a mile. For the City of Carlsbad, this means that more of the material would reach its shoreline (because less is returning to Oceanside Harbor) if the spoil is placed farther from the harbor, and that it should encourage the disposal locations to be moved as close to its boundary as possible. Furthermore, the disposal operations should be scheduled to avoid the season of littoral drift reversal. The consultants to the City should investigate various options with sufficient supporting scientific evidence to press the points maxi- mizing the benefit to the Carlsbad shoreline. As shown in Figure 3-7, the San Diego Gas and Electric Co. carries out beach disposal of the dredge spoils originating from the Agua Hedionda lagoon. Whereas the dredger is most interested in removing the spoils to a location where they are least likely to return to the lagoon, the City is most interested in keeping the material on the shoreline within the city limit for as long as possible. These interests are es- sentially conflicting to each other, and the city should consider having the consultant speak on its behalf. This role will be extremely impor- tant to the City's shoreline, since the dredge volume from Agua Hedionda ranges from as much as about 250,000 to 500,000 cy every two years. Other important areas where the consultant could prove highly valu- able may include, but not be limited to, an assessment as to the downcoast limit of the adverse effect of Oceanside Harbor, emergency measures against freak storms, coastal water quality associated with'off- shore sewage disposal, rip tide predictions. 19 Y 5 b 20 4.0 BEACE PROFILING TASK As part of the overall Sand Survey and Beach Profile Program, shallow- water profiles are to be obtained at eleven (11) stations, while deep-water profiles are to be obtained at four (4) stations. The surveys are to be con- ducted on a semi-annual basis and documented by written reports. Tekmarine's proposed approach to these specific tasks are described in this section. 4.1 Project Team Mr. Chris Butcher shall serve as the Project Manager and be the principal liaison with the City of Carlsbad. He is presently managing the nearshore surveying program being conducted for the COE, as well as the field surveys associated with the Batiquitos Lagoon Enhancement Project. Mr. Butcher will supervise and participate in the field sur- veys, data analysis, and report preparation. Dr. Sonu, the President of Tekmarine, will be primarily responsible for expert data analysis and interpretation, but will also make one-day reconnaissance trips to the Carlsbad shoreline on a bi-monthly basis. He is currently managing the coastal engineering and beach nourishment design services associated with the Batiquitos Lagoon Enhancement Project, and recently completed a review of sediment budget methodology specific to the Oceanside littoral cell for the COE. Mr. Butcher and Dr. Sonu have worked together for 10 years. Combining their resources with those of the Tekmarine staff, we are able to provide the turnkey service of field data acquisition with expert data analysis and interpretation. 21 4.2 Survey Hethodology 4.2.1 Location of Survey Stations Semi-annual beach surveys have been performed in the cities of Carlsbad and Oceanside on a regular basis since December, 1981. From December, 1981 to February, 1983, the surveys were jointly sponsored by Carlsbad and Oceanside. The Carlsbad-sponsored surveys were concentrated between Buena Vista and Agua Hedionda Lagoons and consisted primarily of wading surveys. From November, 1983 to the present, the surveys have been sponsored by the USACOE/LAD as part of the CCSTWS. The latter sur- veys are widely-spaced but extend throughout the city limits and include both wading and boat surveys. Tekmarine has performed the COE-sponsored surveys since April, 1986, and is under contract to continue the surveys through April, 1988. To enhance the data collected in this program, Tekmarine proposes to locate the survey stations in consideration of the foregoing surveys, and thereby maximize the benefit to the City of Carlsbad. The ap- proximate location of the proposed survey stations as well as those for the on-going COE-sponsored surveys are illustrated in Figure 4-1. The proposed locations are selected to complement the COE-sponsored surveys and provide a nearly-uniform distribution of wading and boat surveys throughout the City of Carlsbad. Furthermore, as many of the proposed stations as possible are located at the site of the previous city- sponsored surveys, as illustrated in Figure 4-1. By re-occupying the original survey monuments, a direct comparison may be made between the profiles for the proposed and historical surveys. Special attention is called to the fact that two of the proposed wading survey stations are located just north of the City of Carlsbad in Oceanside. These stations are situated near the southern terminus of the Oceanside Harbor bypass disposal area and are critical to tracking the alongshore migration of sand. 22 c -. . LO-a3 2.. W t "l D C m >. W t .4 D : 2 a P ,- . 4.2.2 Wading Surveys As specified in the Request for Proposal, Tekmarine proposes to utilize wading and boat surveys to obtain the shallow- and deep-water profiles, respectively. A conceptual representation of these methods, which Tekmarine has employed successfully for the COE since April, 1986, is illustrated in Figure 4-2. The accuracy of these methods shall satisfy the following criteria, which are the same as those established by the COE for their surveys: Survey Method Vertical Accuracy Horizontal Accuracy + + -1.0 ft -10.0 ft + + Wad i ng -0.1 ft Boat -0.5 ft The wading survey shall be conducted by a two-person crew equipped with a Geodimeter Model 122 Electronic Distance Meter (Ref. Fig. 4-2). The Geodimeter is selected because it has a wide beam divergence and be- cause its fast-tracking mode determines the range and elevation of the survey rod reflector in less than one second. These attributes greatly expedite data acquisition in the surf zone, where the rod is stationary for only brief intervals between wave impacts. Following are the standard operating procedures employed by Tekmarine for previous surveys. Similar procedures are proposed for this study. 1) The range line monument was located and the alignment was estab- lished with a hand-bearing compass. 2) Two range markers were erected on the range line to indicate its alignment. 3) The EDM was positioned on the range line and checked for proper operation. 4) Notes on the beach composition, weather, and sea conditions were recorded. 5) The survey was initiated with a backsight to the monument. 24 3 aI -u 2 E/ a! 7 I I I I I I 41 I .T 6) Distances and elevations were measured at intervals of 30 to 40 ft, and at major slope breaks, from the monument to the specified depth. Bottom composition was noted by the rod man, if discern- i ble. 7) Additional random points along the range line were surveyed as a check on the original data as the rod man returned to the monument for a closing backsight. In addition to the foregoing, a photographic station shall be es- tablished at each station and at an intermediate point between stations where alongshore and on-offshore photographs shall be taken during each survey. Utilizing the fast-tracking geodimeter, a strong swimmer, and an extendable surf rod, the wading survey shall be extended to a minimum depth of 3 m, MLLW. Tekmarine has routinely performed wading survey to these depths in Carlsbad and other southern California areas since April, 1986 (see Plate 4-1). The benefits accuring from extending the wading surveys to these depths include the following: o Providing profile data in the most active sediment transport zone even at survey stations where boat surveys are not performed. o Producing significantly greater accuracy in the region of most ac- tive sediment transport than could be obtained with boatlfathometer surveying techniques. o Enabling the boat surveys to be performed without regard to the tidal stage, and enabling a substantial overlap between the vading and boat sut-veys. The overlap bet-*,een the ;lading and boat surveys provides a Teans of quality control in that the two independent surveys can be checked against one another iii fht legion of overlap. The overlap hetwpen the , ! (1 _- PLATE 3-1. IZADIXG SURVEY SEAWARD OF THE BREAKER ZONE USING EXTESDABLE SURL’EY ROD (RANGE LINE CB-0760). PLATE 3-2. FATHOMETER SURVEY USING INFLATABLE BOAT. RANGE LINE MARKERS IN BACKGROUND. wading and boat surveys performed at Range Line CB-0830 in October, 1986 by Tekmarine is illustrated in Figure 4-3. 4.2.3 Boat Surveys The boat surveys shall be performed by a two-person boat crew using an analog fathometer, and a two-person shore party using an EDH to deter- mine the boat position (ref. Fig. 4-2). The inflatable boat proposed for the survey, a Zodiac Mark I11 GR (see Plate 4-2), offers two distinct advantages relative to a displacement hull: 1) maneuverability and shal- low draft, which are essential for data acquisition near the breaker zone, and 2) resistance to roll, which results in reduced contamination of the fathometer record by waves. The ability of the Zodiac to operate near and even in the breaker zone enables the boat survey to extend landward to a typical depth of minus 8 to 10 ft, thereby creating sub- stantial overlap with the wading survey. Depths shall be measured with a Raytheon DE719C Fathometer Depth Recorder, which provides a continuous analog record of the seafloor on a strip chart. By virtue of its precision, portability, ruggedness, and low power consumption, the DE719C is well-suited to small-boat survey operations. The position of the survey boat shall be determined with a Geodimeter Model 122 EDH operated by the shore party.. As in the case of the wading survey, the rapid response and wide beam divergence of the. Geodimeter greatly expedites the boat tracking operation. Following are the standard operating procedures employed by Tekmarine for previous boat surveys. Similar procedures are proposed for this study, for which Tekmarine shall extend the boat lines to a minimum depth of 40 ft, MLLW. 2a a a x dd w -N I- W i: 0 m I 0 0 0 m 3 13 3 3 3 3 r) 3 3 3 U 3 3 3 I 29 1) The range line monument was located and the alignment was estab- lished with a hand-bearing compass. 2) The shore party erected two high-visibility range markers on the range line to indicate its alignment (ref. Plate 4-2), and estab- lished radio contact the the survey boat. 3) The EDH was postioned on the range line and checked for proper operation. 4) A backsight to the monuent was recorded to establish the horizontal position of the EDH. 5) While the shore party performed Tasks 1 through 4, the boat crew calibrated the fathometer. 6) The boat was positioned at the seaward terminus of the range line. Just prior to commencing the survey run, the shore crew directed the boat to the exact range alignment by radio. 7) When the boat was on range, the shore crew notified the boat crew to commence the survey run. As the boat proceeded landward, the shore crew recorded the distance to the boat at 10-second intervals while simultaneously directing the boat crew to place an event mark on the fathogram. The boat speed was typically constant at 4 knots, resulting in a spacing of 70 ft between the successive pairs of depth-distance measurements. 8) The survey run continued until breaking waves or shallow water forced the boat crew to abandon the range line. 9) A second survey run was conducted immediately after the first with the boat proceeding in an offshore direction. 30 - - _- 10) At the conclusion of the survey runs, a final calibration check was performed on the fathometer. Three procedures shall be routinely adopted to assure quality con- trol of the boat survey data: o Fathometer "bar check" calibrations at each range line. o Two boat surveys at each range line. o Extending boat surveys inshore until they overlap the wading sur- vey. Because the speed of sound in sea water varies with the water den- sity, because water density can change abruptly along the coast due to such factors as river discharge, upwelling, and coastal density fronts, the fathometer shall be calibrated at each survey station. The calibration procedure known as a "bar check", is depicted in Figure 4-4. An initial calibration is accomplished by suspending a sonically reflec- tive bar beneath the transducer at a depth of minus 10 ft, and adjusting the instrument readout to this depth. To account for water column varia- tions in the speed of sound which may occur in the water column, the bar is lowered in 10-ft increments to a maximum depth of minus 40 ft and raised in similar increments to the original depth of minus 10 For each known bar depth (-10, -20, -30, and -40 ft), the difference between the actual bar depth and the fathometer readout is noted. These dif- ferences are subsequently used to develop a speed-of-sound correction curve which is applied to all fathometer data obtained for that par- ticular range line. and ft. If the calibration line on the fathometer drifts during the survey, the bar check procedure shall be repeated with minor changes at the con- clusion of the survey.

The results are then averaged with the pre-survey data in developing the final speed-of-sound correc- tion curve. Experience has indicated, however, that fathometer drift proves to be insignificant. Of course, should a major instrument drift occur during a survey, the entire calibration and survey would be repeated . The practice of performing two boat surveys shall be adopted at each range line. In addition to providing confirmation of the survey accuracy, the double runs aid in distinguishing seafloor features such as rock outcroppings from wave contamination of the fathograms. By conduct- ing successive runs in opposite directions along the range line (onshore and offshore), the encounter frequency of the survey boat with the incom- ing waves is altered. This shift changes the nature of the wave contamination in the two fathograms, permitting the bottom features to be more easily recognized. As a final quality control measure, the boat survey shall be ex- tended inshore until it overlaps with the wading survey. During data processing, this overlapping region shall be compared to verify agreement between the two independent surveys. It should be noted that this measure is feasible only if overlap data exists and if the wading and fathometer surveys are performed within a short time of one another, say 24 hours. If the wading and boat surveys are separated by a substantial time period, comparison of the overlapping data is invalidated due to the possibility of naturally occuring profile changes between the surveys.' As previously discussed, our proposed survey methods ensure a substantial overlap and eliminate the dependence on the tidal stage, thereby making it possible for us to perform this quality control measure. 33 4.3 Survey Reports Dr. Sonu shall submit a letter report following each of his bi- monthly one-day reconnaissance trips to Carlsbad. More extensive survey reports shall be submitted to the City of Carlsbad following each of the semi-annual surveys.

In addition, profiles from the regions north and south of Carlsbad, historical records and other data sources shall be perused for information relevant to con- clusions regarding beach dynamics in the City of Carlsbad, inclusive of data and resources from previous and/or on-going consultants, as avail- able to Tekmarine. Because the October, 1987 survey is a baseline survey, profile com- parisons in the October, 1987 report shall be limited to those stations where historical profiles exist. Following the April, 1988 survey, a complete data set will be available for analysis, from which more com- prehensive conclusions, including a sediment budget, shall be derived. As indicated in the proposed Table of Contents, attachments to the report shall include beach profile computer data files and beach photographs inclusive of the COE survey stations listed above. Tekmarine proposes to submit the data files in the COE BPAS format to make them compatible with historical COE survey data. The data file shall be provided on a medium (e. g., floppy disk, 9-track tape) compatible with the City of Carlsbad computer system. The data may also be provided in other formats for the convenience of City employees, if so desired. 4.4 Schedule Tekmarine believes the survey schedule specified in the Request for Proposal is most appropriate. Conducting the surveys in the months of April and October results in profiles that are representative of the seasonal winter and summer profiles, respectively. Furthermore, these dates coincide with the on-going COE surveys, vhich makes integration of the COE data into the Carlsbad data mol-e meaningful. To provide a 36 "snapshot" of the beaches, Tekmarine proposes to conduct the field sur- veys in a one- to two-day period. Because we propose to include the COE data in our survey reports, our report delivery schedule shall be contingent on the availability of the COE data. To allow time for processing, review, and approval of the COE data, we propose to deliver our survey report approximately three months after each field survey. During the interim, we shall provide preliminary results in the form of a letter report. 37 5.0 COSTS The Committee has requested that the Consultant provide a fixed-price for the execution of the two semi-annual beach profile surveys inclusive of the written survey reports. Tekmarine proposes to provide these services, as out- lined in Section 4, at the following cost: October, 1987 Survey and Report $11,284 April, 1988 Survey and Report 8,624 Total: $19,908 The differential in cost between the two surveys is primarily at- tributable to the initial verification and/or establishment of survey station monuments prior to the October, 1987 survey. Consulting services in addition to the foregoing shall be charged in ac- cordance with our standard conditions of engagement, which are summarized in Appendix B. .- REFERENCES Dolan, T.J., P. G.
