Project construction activities included removing existing grouted rip-rap, controlling erosion by reducing incoming storm water velocity, replacing the culvert outfall ramp with ungrouted rip-rap, and replanting the stream banks with native riparian habitat to help stabilize the stream bank. The Project also involved construction of two crib walls (one on either side [upstream and downstream] of the existing culvert) using cut tree logs. To add structural integrity to the stream bank, the crib walls were built on 3- foot-diameter foundation boulders that tie into the finish grade. The crib walls were backfilled with angular rock and soil mix to support riparian plants within each crib. Existing grouted rip-rap was removed and replaced with an ungrouted rock-lined ramp and stilling pool to reduce flow velocity before entry into Agua Hedionda Creek. Existing grouted rip-rap in the creek was removed and replaced with two rock-lined step pools. The step pools were contoured with boulder risers, and pool bottoms were restored with streambed material appropriate for Agua Hedionda Creek. Project construction activities resulted in temporary impacts to 0.001 acre (8 linear feet) and permanent impacts to 0.038 acre (152 linear feet) of streambed waters of the United States and/or state. The Project was issued a Clean Water Act Section 404 permit from the U.S. Army Corps of Engineers (USACE) (File Number SPL-2015-00840-WSZ) using Nationwide Permit 13, Bank Stabilization, and the Project was also issued a Clean Water Act Section 401 General Water Quality Certification for Small Habitat Restoration Project from the San Diego Regional Water Quality Control Board (RWQCB) (File Number R9-2015-0184). California Department of Fish and Wildlife (CDFW) issued a letter dated January 20, 2016 regarding Streambed Alteration application No. 1600-2015-0238-R5 indicating CDFW did not meet the permit review end date of January 13, 2016 and as a result, by law (i.e., Operation of Law), the project may be completed (as described in the permit application/notification) without an Agreement (i.e., permit). Project permits, the USACE signed certification of compliance, and the CDFW letter are included in Attachment A. To Winston Zack (USACE), Alan Monji (RWQCB), Kevin Hupf (CDFW) CC Daniel Zimny (City of Carlsbad), Jim Prine (ESA) Subject Sunny Creek Stream Bank Restoration Completion of the 6-Month Plant Establishment Period From Aaron Andrews (AECOM) Date August 11, 2017 Subject: Sunny Creek Stream Bank Restoration 6-Month Plant Establishment Period Completion August 11, 2017 Page 2 Consistent with the Project permits listed above and in accordance with the goals presented in the restoration plan (Balance Hydrologics, Inc. 2015), revegetation of the stream bank occurred concurrently with construction and included both native container plants and a native seed mix of persistent coastal San Diego native plants that support bank stabilization and sediment control. While four coast live oak (Quercus agrifolia) trees were recommended for removal to facilitate the work and the agreed replanting ratio was 2:1 for each oak tree removed, only two coast live oak were removed and a total of eight were planted. In compliance with the permits issued by USACE and RWQCB, an “As-Built” memorandum (fulfilling special conditions 5 and 6 of USACE 404 Permit File Number SPL-2015-00840-WSZ and condition 6 of RWQCB Section 401 File Number R9-2015-0184) was submitted to the respective agencies on January 25, 2017, which documents Project construction activities and final Project impacts. The Project’s 6-month plant establishment period (PEP) began on December 21, 2016, following completion of container plant installation and seeding. The purpose of this memorandum is to document the required revegetation, maintenance, and monitoring activities performed during the 6-month PEP, which was completed on June 20, 2017, and to inform the agencies of the start of the 1.5-year restoration maintenance period and 2.5- year restoration monitoring period. Year 1 of the Project includes the 6-month PEP. Provided below are a summary of native plant installation; qualitative monitoring, maintenance, and quantitative monitoring conducted during the 6-month PEP; and recommendations and future work. Representative photographs are also included. NATIVE CONTAINER PLANT INSTALLATION Native container plant installation was initiated on December 12, 2016, and the bulk of the native container plant installation and broadcast seeding was completed on December 21, 2016, which marked the beginning of the 6-month PEP. Tables 1 and 2 provide the plant palette and seed palette, respectively, and list the species and quantities installed to date. The only species not installed from the planned plant palette was narrow-leaf willow (Salix exigua); substitutions for this species included other willow (Salix sp.) species. The full complement of western sycamore (Platanus racemosa) (i.e., remainder not installed by December 21, 2016) and coast live oak were planted May 9, 2017, as well as additional willows installed in the downstream edge of the Project where erosion damage was repaired. Plant species substitutions and changes to species quantities are reflected in Table 1. All planting deviations were approved by the Project team and documented in the “as-built” drawings (Attachment B) and memorandum submitted to the agencies January 25, 2017.

During each qualitative site visit, the restoration ecologist evaluated the following: • Overall site conditions • Overall hydrological functions • General condition of plants, including plant health/vigor and mortality • Native plant recruitment • Potential issues including hydrology, irrigation problems (too much or too little), invasive nonnative species of concern, erosion, vandalism, and other problems that need to be addressed by the installation or maintenance contractor Following each qualitative site visit, the restoration ecologist provided the City of Carlsbad an observation report detailing topics such as replacement of dead or diseased plants, weeding, irrigation scheduling, erosion control needs, trash removal, and pest control. In addition, the restoration ecologist coordinated with the maintenance contractor on the following activities: • Scheduling upcoming maintenance based on the needs and priorities of the restoration site • Identifying any problems, including erosion and occurrence of invasive nonnative species • Providing support to field maintenance crew in the identification of native and nonnative species • Determining an irrigation schedule (for a given period of time) based on seasonal and annual variation in rainfall, native plant water requirements, and site-specific conditions (e.g., soil condition and slope) MAINTENANCE During the PEP, the maintenance contractor provided maintenance of the restoration site twice per month in accordance with the goals presented in the restoration plan (Balance Hydrologics, Inc. 2015). Maintenance activities included irrigation, supplemental plant installation, trash removal, erosion control within the restoration site, and/or nonnative plant species treatment, as needed, based on results of qualitative monitoring and direction from the restoration ecologist. EROSION In February 2017, a large storm caused erosion at the downstream end of the Project site where the log crib and fiber encapsulated soil system ties into the existing stream bank. The crib wall system was designed to withstand the 20-year storm event but this event created flow levels peaking closer to a 100-year storm event. Had the site been established, it may have withstood such an event. Because the site had not yet had a sufficient amount of time Subject: Sunny Creek Stream Bank Restoration 6-Month Plant Establishment Period Completion August 11, 2017 Page 5 to become established (i.e., installed plants and trees did not yet have established root systems), erosion damage occurred at several locations on-site. Erosion occurred to the stream bank on the upstream end adjacent to the edge where the large boulders tied into the stream bank, and as a result several plant basins were eroded and some plants were swept away. The primary damage occurred to the downstream end where approximately 2 cubic yards of soil were eroded from the tie in location. To repair the erosion, several more plants were installed at the upstream location to help stabilize the existing stream bank. The locations where plant basins were eroded were backfilled with additional soil slurry and replanted. The larger downstream erosion location was backfilled with three boulders and additional fiber encapsulated soil rolls were layered in. At the toe of the slope, a 4-foot tree wad was installed and an additional boulder added in front of the tree wad. Voids between the tree wad, boulder, and edges were backfilled with burlap bags filled with soil slurry and then planted with eight 1-gallon-sized arroyo willows. The erosion areas will continue to be monitored through the remainder of the Project to determine if additional measures need to be implemented. QUANTITATIVE MONITORING Quantitative monitoring for the Project is conducted by making an assessment of the site in comparison to the following PEP success criteria, presented in the restoration plan (Balance Hydrologics, Inc. 2015), "Container plants will have a minimum of 90% survival, cuttings will have a minimum 60% survival, and seeded areas will have a minimum of 50% cover with native vegetation and free of nonnative invasive species." On June 6, 2017, a site meeting with the City of Carlsbad, the landscape architect, and the restoration ecologist was conducted to determine any outstanding issues on-site that the contractor would need to resolve prior to approving completion of the 6-month PEP. During the same visit, the quantitative monitoring was conducted and it was determined that all PEP success criteria have been achieved (Table 3). Only two container plants appear to have died (i.e., 99% survival), more than 75% of the cuttings are alive, and total native cover on the seeded areas is greater than 50% total cover (i.e., approximately 50-65% total cover based on visual estimate). Table 3 Performance Criteria and Site Status Performance Criteria Monitoring Results Performance Status Container plants 90% survival 99% survival Criterion achieved Willow cuttings 60% survival 75% survival Criterion achieved Seeded areas 50% cover native species 50–65% cover Criterion achieved 0% nonnative invasive species 0% invasive species Criterion achieved RECOMMENDATIONS AND FUTURE WORK At the end of the 6-month PEP, AECOM recommended approval of the 6-month PEP and beginning of the remaining1.5-year maintenance period starting June 21, 2017. Year 1 is inclusive of the 6-month PEP. Maintenance and monitoring will continue as presented in the Subject: Sunny Creek Stream Bank Restoration 6-Month Plant Establishment Period Completion August 11, 2017 Page 6 restoration plan (Balance Hydrologics, Inc. 2015). The remainder of the expected Year 1 work is summarized below: • Irrigation through the summer months is expected to occur two times per month (through September) and then reduced in the fall (expected in October-November) until the plants do not require supplemental irrigation because they are self-sufficient • Nonnative plant treatment • Erosion control as necessary • Installation of additional willow cuttings in and around the erosion repair area, work to occur in the fall as willows go into the winter dormancy The next monitoring report that is scheduled to be submitted to the agencies is the Year 1 annual monitoring report, which is expected to be submitted in February 2018. SITE PHOTOS Site photos taken at the permanent photo points (Figure 1) are included; these photos were taken prior to construction, and at the start and end of the 6-month PEP (Figures 2 through 6). These photos will be used in future reporting to compare site conditions throughout the remaining maintenance and monitoring program.

The Project will build one crib wall on the east and two crib walls on the west side of the existing culvert with cut tree logs. To add structural integrity to the stream bank, the crib walls will be built on three foot diameter foundation boulders which will conform to the finished grade. The crib walls will be backfilled with angular rock and soil mix to support riparian plantings at each step. Four oak trees along the stream bank will need to be removed to facilitate the work and the minimum setback from all other trees will be 1 0 feet. The Applicant will plant new oak trees at a 2:1 for each oak tree removed for this Project. See Enclosure 1 and 2 for the Project location. City of Carlsbad Sunny Creek Rd Restoration R9-2015-0184 - 3 -January 27, 2016 Existing grouted rip-rap in the culvert will be removed and replaced with a rock lined (ungrouted) ramp with a stilling pool to reduce the velocity and turbulence of the flow before it enters the Agua Hedionda Creek. Existing grouted rip-rap in the Creek will be removed and replaced with two rock lined step pools. The step pools will be contoured with boulder risers and pool bottoms will be restored with streambed material appropriate for Agua Hedionda Creek. Revegetation of the stream banks will occur concurrently with the construction and will include both native container plantings and broadcast seed mix of persistent coastal San Diego native plants that will support bank stabilization and sediment control. See Enclosure 3 for the conceptual design. Project activities will result in temporary impacts to 0.001 acre (8 linear feet) and permanent impacts 0.038 acre (152 linear feet) of streambed waters of the United State and/or State.
