This dryback is proposed in conjunction with the Stevens Creek Corridor Park and Restoration, Phase 2 Project for which permits have been requested by CITY from the U.S. Army Corps of Engineers. The United States National Oceanic and Atmospheric Agency (NOAA) Fisheries has requested details on the methodologies to be used in dewatering, rewatering, and relocating fish from the dryback zone in conjunction with the preparation of a Biological Opinion for the Central California Coast Distinct Population Segment (DPS) Steelhead (Oncorhynchus mykiss), a species protected under the U.S. Endangered Species Act of 1973, as amended (16 USC 1531 et seq.). Work will be performed to comply with applicable regulatory requirements. The Stevens Creek Corridor Park & Restoration, Phase 2 Project (SCC Phase 2 Project or Project) will extend the Stevens Creek Trail from Blackberry Farm Park to Stevens Creek Boulevard and implement a discretionary stream and upland restoration project along the Blackberry Farm Golf Course and the former"Stocklmeir" property. These actions will carry the trail across the creek on a clear span pedestrian/bicycle bridge and extend it approximately 1/4 mile to connect with bicycle lanes and bus stops on Stevens Creek Boulevard. The SCC Phase 2 Project will restore approximately 660 feet of riverine habitat and approximately 1% acres of cottonwood-sycamore riparian and oak woodland forest, along approximately ' mile of the 60 acres of publicly-owned land in the creek corridor. The Project includes the demolition and removal of concrete and riprap lining on the east creek bank, relocation of a sanitary sewer main to allow for the widening of the channel along its east side to create an inset floodplain bench, installation of several pool and riffle sequences interspersed by paired boulder steps and approximately 40 woody debris structures as fish habitat, creation of a 90 foot backwater off the west bank, placement of a vegetated log cribwall to protect downstream property, an optional (bid alternate) creek bank layback on the west bank and the installation of approximately 2,000 locally collected and contract grown riparian and oak woodland plants representing more than 60 native species. II. DISTRICT-PROVIDED SERVICES A. Principal Biologist—DISTRICT will provide biological assistance and additional qualified consulting biologists if needed to implement the fish relocation actions described in this Agreement. SCVWD/City of Cupertino Cooperative Agreement Blackberry Farm Park and Stevens Creek Restoration Project,Phase 2 April 2013 Page 1 of 8 B. Estimated Schedule—The current estimated schedule provides for the DISTRICT Principal Biologist to provide biological team training to DISTRICT, CITY and construction contractor's staff during the last week in May 2013. Dewatering and fish relocation is planned to take place approximately within the June 24-29, 2013 timeframe, or as otherwise coordinated with CITY'S construction contractor executing the Project. Fish relocation will occur throughout the day to expedite the construction schedule. A limited fish relocation effort will be undertaken a few days in advance for the construction of the cofferdams. Rewatering of the channel is scheduled to occur no later than October 31, consistent with the expected environmental regulatory permits. C. Biological Team Training—DISTRICT staff shall conduct a biological team training for DISTRICT and CITY staff at a mutually agreeable time, on or around late May 2013. The purpose of this training is to familiarize DISTRICT, CITY and construction contractor's staff with the site and the capture protocols, drive routes to release sites, finalize the Project schedule and make any other necessary adjustment to the fish relocation operation. The training is anticipated to occur approximately two to four weeks in advance of the fish relocation effort in order to provide ample lead time for near term adjustments to the conditions close to the time of Project initiation. The training will ensure all team members are aware of the procedures for this fish relocation effort including equipment, drop off locations, transportation routes, etc. III. OVERVIEW OF DEWATERING OPERATIONS AND FISH RELOCATION EFFORTS The dewatering operation will be coordinated with the CITY'S Project construction contractor. The contractor will install the upstream fish screen will which remain in place throughout construction and then turn the site over to the fish relocation team. The fish relocation operation will occur in two phases. The primary phase will commence with the installation of a temporary downstream block net by the fish relocation team. The primary phase will include systematically electrofishing segments of the live creek channel and relocating captured fish to nine predetermined release sites. Securing and relocating the majority of the fish from the live channel in phase one will minimize the potential for mortality during the actual dewatering of the channel. The fish relocation team has 14 calendar days to electrofish and relocate native species before transferring the stream to the contractor to construct the cofferdams. Upon completion of the cofferdams, full dewatering will commence and the fish relocation team will begin phase two of the relocation working in conjunction with the contractor to rescue any fish that remain in the channel. The contractor is required to supply water to the site throughout phase two of the dewatering should the fish relocation team encounter any field conditions that make work progress more slowly than anticipated and put any resources at unnecessary risk. The coordination with the contractor is detailed in Appendix A—Temporary Creek Diversion Specifications, attached hereto and incorporated herein by this reference. Details of the sequencing and communication chain will also be re-verified during pre-construction meetings with the construction contractor. SCVWD/City of Cupertino Cooperative Agreement Blackberry Farm Park and Stevens Creek Restoration Project,Phase 2 April 2013 Page 2 of 8 A. Dewatering and Rewatering—CITY'S contractor will be responsible for dewatering and rewatering approximately 800 LF of Stevens Creek. The contractor must submit a dewatering and rewatering plan to the CITY for approval. These plans must meet the DISTRICT'S Stream Maintenance Program Best Management Practices (BMPs) that have been identified in CITY's Project Contract Specifications Section 015736 Temporary Creek Diversion. In addition, the specifications require that the dewatering and rewatering plans meet all permit conditions. B. Fish Relocation Planning 1. Staging—Continuous access is available all along the dryback reach in Blackberry Farm Golf Course and the former"Stockimeir" property for fish capture. Drop-off staging areas are located at points where vehicle access is available through DISTRICT owned property and easement areas. Relocation sites have been selected on the basis of proximity and access to the dryback zone and safe access and operation of equipment. Overland transport on foot has been minimized for this effort to affect more rapid and secure release of fish. 2. Staffing—This fish relocation effort will include one to two electrofishing crews to expedite this work effort and make the site available to the contractor as soon as possible. The contractor has a very limited construction window. Each crew will include 1 electrofishing operator, 2 netters, 1 live car handler, 2 bucket handlers and 1 recorder. Bucket handlers and recorders will also serve as the fish release team. 3. Collection and Transport Methods—The methods included in this fish relocation plan have been selected to maximize efficiency of collection effort while minimizing handling and transport time/stress. Electrofishing will be used to capture the fish for relocation. Local transport of fish may be implemented by various methods including: a. Net transfer will be used by the stream team to move fish from the channel to live cars in the stream and by transfer from the live cars to buckets. b. Live cars will be used for short term holding in-stream while collection is active. c. Buckets will be used for transfer of fish from the collection team to the live wells at the transport truck and from live wells to stream at drop-off points. 4. Capture Zones—The approximate 800 LF dryback zone will be divided into segments using block nets for electrofishing. The segmenting of the channel will take into consideration habitat quality evaluating areas where larger numbers of fish are anticipated, natural or man-made features SCVWD/City of Cupertino Cooperative Agreement Blackberry Farm Park and Stevens Creek Restoration Project,Phase 2 April 2013 Page 3 of 8 which would provide good locations for erecting block nets, ability of crew to effectively fish the distance in a half day and other factors. Pre-construction work will include trimming back and removing the overgrown understory vegetation along the project channel prior to electrofishing to ensure clear and efficient access. Each segment will be initially fished as a reach isolated by nets until the surface stream flow breaks. The concrete-lined segment will be fished first since it is expected to dewater most rapidly. The segments will initially be fished from downstream to upstream then progressing to remaining pools in the segments as the stream breaks continuous surface flow and remaining pools become more fully accessible. 5. Relocation Sites—Specimens rescued will be transported upstream and downstream, and if possible, estimates during processing will be made to distribute fish equally among drop-off sites. The drop-off areas are all accessible to the general fish population in the stream. By default, fish will not be moved over substantial barriers or long distances upstream to avoid problems with disease transmission to unaffected populations. Steelhead smolts and adults captured during this fish relocation effort will be moved downstream to flow that runs continuously to San Francisco Bay. 6. Drop-off Positions—Seven relocation options have been identified for young of year, 1+/2+ steelhead, resident rainbow trout and other native fishes. These sites are all located within the "Cold Water Management Zone" or within the two miles downstream of this zone and are wet throughout the summer. The two miles downstream of the existing "Cold Water Management Zone" are identified as possible expansion of the "Cold Water Management Zone."These sites offer excellent access to afford a swift release of relocated fish. Final selection of release sites will be dependent upon quantity of fish captured and the water releases from Stevens Creek dam that are collaboratively discussed and determined each year with DFG and NMFS. Releases are dependent upon each year's rainfall and reservoir capacity. If releases are reduced the year of the fish relocation the two sites located the farthest downstream may not be used as release sites due to the potential for summer dryback. Temperature and dissolved oxygen (DO) will be measured at each relocation site prior to release to ensure that minimum conductions are met. These proposed release sites are listed below and can be viewed in Appendix C—Fish Relocation Sites Maps, attached hereto and incorporated herein. a. McClellan Ranch Park b. Stevens Creek County Park—Parking Lot c. Upstream of Blackberry Farm Golf Course—Restored Phase 1 Project SCVWD/City of Cupertino Cooperative Agreement Blackberry Farm Park and Stevens Creek Restoration Project,Phase 2 April 2013 Page 4 of 8 d. Stevens Creek Boulevard e. Homestead Road f. Upstream of Fremont Boulevard at Morton* g. Fremont Boulevard* *Optional downstream positions depending on reservoir operations and reduced summer season releases by Cold Pool Management in dry year conditions. These sites will only be used if the summer flow will have a high likelihood of extending substantially through the reach. (Summer Reservoir Operations discussion pending with NMFS and California Department of Fish &Wildlife (DFW.) Two downstream relocation options have been identified for smolts and adult steelhead. These sites typically have permanent flow that extends to SF Bay per accretive groundwater conditions. These sites are listed below and can be viewed in Appendix C - Fish Relocation Site Maps. a. Moffett Boulevard b. L'Avenida 7. Coast Ecologically Significant Unit (ESU) Steelhead (Oncorhynchus mykiss). However, other native species will also be rescued based upon the following prioritization scheme: • a. Endangered species b. Threatened species c. Species of special concern d. Salmonids not under the above categories (i.e. resident rainbow trout) e. Native fishes not under the above categories Prior surveys leading up to this project have not detected other sensitive aquatic organisms such as California Red-legged Frog. We do not anticipate encountering this species. 8. Resource Agency Contact—The DISTRICT's principal biologist assisting in this transaction, as agreed between the PARTIES, will contact NOAA Fisheries 48 hours prior to the pre-sampling and to the fish relocation efforts. H. Fish Relocation Operation 1. Set Up—Upon arrival at the site, a review of operation sequence and logistics will be discussed. Final field assignments will be designated and equipment deployed. Prior to commencement of operations, review of safety and operation methods will be conducted. Elements may include: site access considerations; local hazards; environmental considerations; media and public safety; equipment operation; risks associated with collection methods. SCWVD/City of Cupertino Cooperative Agreement Blackberry Farm Park and Stevens Creek Restoration Project,Phase 2 April 2013 Page 5 of 8 2. Live Well Operation—Live well operation will commence first at site deployment to set and stabilize tank conditions. Live wells will be of clean plastic coolers >=100 qt. volume. a. Clear ambient stream water will be used to fill live wells. b. Temperature and oxygen levels will be monitored in live wells during loading and transport: c. Temperature of live wells will be reduced and managed at 5–10_F below ambient water to lessen the stress in fish but at the same time avoiding thermal shock. d. Live well aeration system will be started prior to placing fish to ensure that sufficient oxygen is present during the adjustment period. The aeration rate and number of fish in a live well will be managed such that the dissolved oxygen concentration in live wells will be greater than 6ppm but less than saturation. Each salvage team will have at least two recirculating live wells per transport vehicle and a third will be held in reserve for smolts and adults. Fish will be segregated to the appropriate livewell as they are delivered from the stream. Salmonids will be transported separately from other fish to reduce stress and handling time. To reduce stress in salmonids, at times, a 0.8-0.9 ppt sea salt solution (never exceeding 1.0 ppt), may be used in live well operation to relax the osmotic stress and better manage the temporary crowded conditions. This treatment will also help manage fish fungal and bacterial agents. This will be administered and managed by trained Biologists. 3. Electrofishing Operation—Electrofishing will be used to capture the fish for relocation. Electrofishing will be performed following the "Guidelines for Electrofishing Waters Containing Salmonids Listed Under the Endangered Species Act, June 2000" prepared by the National Marine Fisheries Service under the Endangered Species Act (See Appendix D, attached hereto and incorporated herein by this reference). The Smith-Root Model LR-24 backpack electro fish units will be employed. Electrofishing equipment unit settings will be adjusted to the conductivity and temperature of the water to minimize possible fish injury. Adjustments will be made in step-wise increments as needed to ensure taxis is achieved but complete tetany is avoided. Recovery time will be monitored to ensure power settings are not over energizing the taxis response. Settings used will be recorded and any incidental electrofishing mortalities will be recorded. If electrofishing mortalities for salmonids begin to exceed 5 % of the total capture, electrofishing activities will cease. Electrofishing will cease if water temperatures exceed 18° C. Fish other than salmonids (i.e. Sacramento suckers), that are mortalities from SCVWD/City of Cupertino Cooperative Agreement Blackberry Farm Park and Stevens Creek Restoration Project,Phase 2 April 2013 Page 6 of 8 electrofishing activities will be noted as an indicator of possible injury or mortality rate to salmonids and other fish. 4. Site Layout and Progression—Block nets will be installed to segment the stream reach. Existing hydraulic breaks will be used as end points with no stream sub-reach longer than -400 ft. as estimated from the mapping layout (See Appendix C - Fish Relocation Site Maps, attached hereto and incorporated herein by this reference). Multiple passes will be made in each segment to clear that reach subdivision of fishes before the next reach is accomplished. The Project reach will be isolated by block nets and screening. As a sub-reach is cleared, the interior upstream net will be left in place to become the downstream block net of the next section cleared. Leapfrogging the sections and nets will keep cleared sections from being reinoculated as work progresses. Separate electrofishing salvage crews will be operating at least two sections apart to minimize turbidity transfer downstream that might hamper the downstream team efficiency. 5. General Collection Guidellines—Collection of fishes will be conducted in a manner to minimize handling time and stress, yet maintain the safety of the ground personnel. a. Multiple buckets and/or live cars will be used to reduce crowding during collection and transfer. b. Pre-sorting fish will be conducted on an as-possible basis as they are captured for transport to a live well. c. Buckets that hold salmonids until subsequent release into the live wells for transport will be equipped with portable aerators. 6. Transport a. Transport of fish will be conducted to minimize holding time and alternately sequenced in tandem with ongoing collection activities. b. Transportation of relocated fish will be by qualified personnel only. Qualified biologists will accompany and supervise transport and drop-off actions. c. Normal live-well operations will be continued during transport. d. Mobile communications will be carried in transport vehicles. 7. Records and Data a. Documentation of fish relocation efforts will be undertaken at the time of operations using standardized forms. SCVWD/City of Cupertino Cooperative Agreement Blackberry Farm Park and Stevens Creek Restoration Project,Phase 2 April 2013 Page 7 of 8 b. Fish will be inventoried and other pertinent specimen data recorded if circumstances allow. If conditions preclude detailed inventory, a list of the species present and an estimation of their abundance should be documented along with their disposition (i.e., released, mortality (+reason), sacrificed, salvaged). c. Information on ambient site conditions, including photo- documentation at collection and release sites will be gathered. d. Information on collection and handling methods and transport conditions will be recorded. e.

It is expected that these guidelines will help improve electrofishing technique in ways which will reduce fish injury and increase electrofishing efficiency. These guidelines and sampling protocol were developed from NMFS research experience and input from specialists in the electrofishing industry and fishery researchers. This document outlines electrofishing procedures and guidelines that NMFS has determined to be necessary and advisable when working in freshwater systems where threatened or endangered salmon and steelhead may be found. As such,the guidelines provide a basis for reviewing proposed electrofishing activities submitted to NMFS in the context of ESA Section 10 permit applications as well as scientific research activities proposed for coverage under an ESA Section 4(d)rule. These guidelines specifically address the use of backpack electrofishers for sampling juvenile or adult salmon and steelhead that are not in spawning condition. Electrofishing in the vicinity of adult salmonids in spawning condition and electrofishing near redds are not discussed as there is no justifiable basis for permitting these activities except in very limited situations(e.g.,collecting brood stock, fish rescue,etc.). The guidelines also address sampling and fish handling protocols typically employed in electrofishing studies. While the guidelines contain many specifics,they are not intended to serve as an electrofishing manual and do not eliminate the need for good judgement in the field. Finally, it is important to note that researchers wishing to use electrofishing in waters containing listed salmon and steelhead are not necessarily precluded from using techniques or equipment not addressed in these guidelines(e.g.,boat electrofishers). However,prior to authorizing the take of listed salmonids under the ESA,NMFS will require substantial proof that such techniques/equipment are clearly necessary for a particular study and that adequate safeguards will be in place to protect threatened or endangered salmonids. Additional information regarding these guidelines or other research issues dealing with salmon and steelhead listed under the ESA can be obtained from NMFS' Protected Resources Divisions in: Washington.

With over 25 Evolutionarily Significant Units(ESUs)of threatened or endangered salmonids now identified along the U.S. West Coast,researchers can expect to encounter one or more listed species in nearly every river basin in California,Oregon,Washington,and Idaho. There are few if any non-invasive ways to collect distribution,abundance,or morpho- physiological data on salmonids in freshwater. This is reflected in the requirement that all activities that involve intentional take of juvenile salmonids for research or enhancement of an ESA listed species require an ESA Section 10 permit from NMFS. While NMFS has not precluded the use of electrofishing in all cases,researchers must present rigorous study designs and methods for handling fish prior to NMFS authorizing electrofishing to take listed salmonids under the ESA. NMFS believes there is ample evidence that electrofishing can cause serious harm to fish and the general agency position is to encourage researchers to seek out other less invasive ways to sample listed species. Direct observation by snorkeling is one of the least invasive ways to collect information concerning abundance and distribution, although there can be both practical(e.g.,poor viability)and statistical(e.g., large numbers of fish, low observation probability)constraints to direct observation. Preliminary efforts should be directed at study designs that use less invasive methods. If such methods cannot provide the quality of data required or when the benefit exceeds potential mortality risk,then electrofishing can be considered. Electrofishing used on a limited basis to calibrate direct observations(e.g.,Hankin and Reeves 1988)is commonly used and methods are currently under development that increase the use of direct observation counts(e.g.,bounded counts,"multiple snorkel passes")which, in many cases,will further reduce the need for electrofishing. Electrofishing Guidelines Training Field supervisors and crew members must have appropriate training and experience with electrofishing techniques. Training for field supervisors can be acquired from programs such as those offered from the U. S. Fish and Wildlife Service-National Conservation Training Center(Principles and Techniques of Electrofishing course)where participants are presented information concerning such topics as electric circuit and field theory,safety training,and fish injury awareness and minimization. A crew leader having at least 100 hours of electrofishing experience in the field using similar equipment must train the crew. The crew leader's experience must be documented and available for confirmation; such documentation may be in the form of a logbook. The training must occur before an inexperienced crew begins any electrofishing and should be conducted in waters that do not contain ESA-listed fish. Field crew training must include the following elements: 1. A review of these guidelines and the equipment manufacturer's recommendations, including basic gear maintenance. 2. Definitions of basic terminology(e.g. galvanotaxis,narcosis,and tetany)and an explanation of how electrofishing attracts fish. 3. A demonstration of the proper use of electrofishing equipment(including an explanation of how gear can injure fish and how to recognize signs of injury)and of the role each crew member 2 performs. 4. A demonstration of proper fish handling,anesthetization,and resuscitation techniques. 5. A field session where new individuals actually perform each role on the electrofishing crew. Research Coordination Research activities should be coordinated with fishery personnel from other agencies/parties to avoid duplication of effort,oversampling small populations.,and unnecessary stress on fish. Researchers should actively seek out ways to share data on threatened and endangered species so that fish samples yield as much information as possible to the research community. NMFS believes that the state fishery agencies should play a major role in coordinating salmonid research and encourages researchers to discuss their study plans with these agencies prior to approaching NMFS for an ESA permit. Initial Site Surveys and Equipment Settings 1. In order to avoid contact with spawning adults or active redds,researchers must conduct a careful visual survey of the area to be sampled before beginning electrofishing. 2. Prior to the start of sampling at a new location,water temperature and conductivity measurements should be taken to evaluate electroshocker settings and adjustments. No electrofishing should occur when water temperatures are above 18°C or are expected to rise above this temperature prior to concluding the electrofishing survey. In addition, studies by NMFS scientists indicate that no electrofishing should occur in California coastal basins when conductivity is above 350 µS/cm. 3. Whenever possible, a block net should be placed below the area being sampled to capture stunned fish that may drift downstream. 4. Equipment must be in good working condition and operators should go through the manufacturer's preseason checks, adhere to all provisions, and record major maintenance work in a logbook. 5. Each electrofishing session must start with all settings(voltage,pulse width,and pulse rate)set to the minimums needed to capture fish. These settings should be gradually increased only to the point where fish are immobilized and captured, and generally not allowed to exceed conductivity-based maxima(Table 1). Only direct current(DC)or pulsed direct current(PDC)should be used. Table 1. Guidelines for initial and maximum settings for backpack electrofishing. Initial Maximum Notes settings settings Voltage 100 V Conductivity(µS/cm) Max. Voltage In California coastal basins, settings < 100 1 100 V should never exceed 400 volts. 100 - 300 800 V Also, no electrofishing should occur in these basins if > 300 400 V conductivity is greater than 350µS/cm. Pulse width 500 gs 5 ms Pulse rate 30 Hz 70 Hz In general,exceeding 40 Hz will injure more fish 3 Electrofishing Technique 1. Sampling should begin using straight DC. Remember that the power needs to remain on until the fish is netted when using straight DC. If fish capture is unsuccessful with initial low voltage,gradually increase voltage settings with straight DC. 2. If fish capture is not successful with the use of straight DC, then set the electrofisher to lower voltages with PDC. If fish capture is unsuccessful with low voltages, increase pulse width,voltage,and pulse frequency(duration,amplitude,and frequency). 4. Electrofishing should be performed in a manner that minimizes harm to the fish. Stream segments should be sampled systematically,moving the anode continuously in a herringbone pattern(where feasible) through the water. Care should be taken when fishing in areas with high fish concentrations,structure (e.g.,wood,undercut banks)and in shallow waters where most backpack electrofishing for juvenile salmonids occurs. Voltage gradients may be high when electrodes are in shallow water where boundary layers(water surface and substrate)tend to intensify the electrical field. 5. Do not electrofish in one location for an extended period(e.g., undercut banks)and regularly check block nets for immobilized fish. 6. Fish should not make contact with the anode. Remember that the zone of potential injury for fish is 0.5 m from the anode. 7. Electrofishing crews should be generally observant of the condition of the fish and change or terminate sampling when experiencing problems with fish recovery time,banding,injury,mortality,or other indications of fish stress. 8. Netters should not allow the fish to remain in the electrical field any longer than necessary by removing stunned fish from the water immediately after netting. Sample Processing and Recordkeeping 1. Fish should be processed as soon as possible after capture to minimize stress. This may require a larger crew size. 2. All sampling procedures must have a protocol for protecting held fish. Samplers must be aware of the conditions in the containers holding fish; air pumps,water transfers,etc.,should be used as necessary to maintain safe conditions. Also,large fish should be kept separate from smaller prey-sized fish to avoid predation during containment. 3. Use of an approved anesthetic can reduce fish stress and is recommended,particularly if additional handling of fish is required(e.g.,length and weight measurements,scale samples, fin clips,tagging). 4. Fish should be handled properly(e.g.,wetting measuring boards,not overcrowding fish in buckets, etc.). 5. Fish should be observed for general condition and injuries(e.g., increased recovery time,dark bands, apparent spinal injuries). Each fish should be completely revived before releasing at the location of capture. A plan for achieving efficient return to appropriate habitat should be developed before each sampling session. Also,every attempt should be made to process and release ESA-listed specimens first. 8. Pertinent water quality(e.g.,conductivity and temperature)and sampling notes(e.g., shocker settings, fish condition/injuries/mortalities)should be recorded in a logbook to improve technique and help train new operators. It is important to note that records of injuries or mortalities pertain to the entire electrofishing survey, including the fish sample work-up. 4 Citations and Other References Dalbey, S. R.,T. E.
