1.0 INTRODUCTION

The purpose of the Habitat Restoration Plan (HRP) is to restore native and wildlife habitat by removing invasive nonnative plants and planting native plants to increase plant species diversity and native plant coverage within approximately 9.52ac portion of the Harriett Wieder Regional Park (HWRP) in the City of Huntington Beach, County of Orange, California (Restoration Project). The Restoration Project site is located at the southern end of the Bolsa Chica Wetlands on the north side of Seapoint Avenue between Palm Avenue and Doral Drive, and adjacent to the Bolsa Chica Ecological Reserve (BCER) (Figure 4) (Project Site). This Restoration Project is the first step in the restoration of native habitat at the southern edge of the BCER, which is a relatively narrow undeveloped bluff top area known as the Huntington Beach Mesa (Huntington Mesa).

The Restoration Project is being undertaken by the Bolsa Chica Conservancy (Conservancy) using funds provided by the Orange County Transportation Authority (OCTA) with support from local ecologists and restoration specialists. OCTA is providing Measure M funds ($475,000 approved by the OCTA Board of Directors in 2012) specifically earmarked for mitigating impacts to native habitat resulting from regional transportation improvements. Said funds will be used for the development, installation, maintenance, and monitoring (including long-term) of the Restoration Project. The HRP described on the following pages accomplishes two important public policy objectives; 1) mitigate environmental impacts associated with regional transportation improvements and; 2) implement habitat restoration consistent with the HWRP 1997 Updated General Development Plan previously approved by both the County of Orange and the City of Huntington Beach.

The Conservancy was established in 1990 by a coalition of government, community, business, and environmental leaders. It is a private, nonprofit organization, that provides educational and habitat restoration programs designed to promote public awareness of the important role wetlands play in the coastal marine environment. Since its inception, more than 450,000 visitors of all ages have participated in the Conservancy’s educational and restoration programs throughout the BCER. These programs feature outdoor education and hands-on field activities that allow participants to connect theory with real-life science, including hands-on restoration programs involving native plant propagation and installation as well as nonnative plant management. In addition to educational programs designed for schoolchildren and the visiting public, the Conservancy regularly hosts public outreach events intended to provide the general public with opportunities to participate in cleanup efforts, habitat restoration, and scientific research projects.

In 1992, the County of Orange (County) approved a General Development Plan (GDP) for the 106- ac HWRP. In 1997, the GDP was updated. The GDP calls for HWRP to be primarily passive in nature comprised of native habitat restoration areas, pedestrian trails, scenic overlooks and an interpretive center to provide environmental education opportunities for the public. The County currently owns approximately 34 ac of parkland designated as HWRP. HWRP lies within the jurisdiction of both the County of Orange (7 ac) and the City of Huntington Beach (27 ac).

In 1997, the County and the City of Huntington Beach (City) each approved a Coastal Development Permit (CDP) for that portion of the parkland within their jurisdiction for the Phase 1 improvements to 51-ac of the park located between Garfield Avenue and a helipad serving offshore oil operations. The County CDP was decertified in 1998. The Phase 1 improvements included native habitat restoration, public parking, a neighborhood park node and an interpretive center. At this time, only the neighborhood park has been developed. The habitat restoration and the interpretive center were deferred until funding became available. Using funds from OCTA and in cooperation with OC Parks, the Conservancy will be able to initiate the native habitat restoration called for in the Phase 1 improvement program.

This HRP describes methods to implement 0.17-ac of riparian habitat and 9.52-ac of a mixed ecotone of coastal sage scrub (CSS) and native grassland restoration (9.69-ac total) within HWRP (Figure 3). This Restoration Project would restore an area that is adjacent to an active oil field and on-going restoration efforts at the BCER (Figure 3).

In 2006, the California State Lands Commission, through a collaborative effort between various agencies including the United Stated Fish and Wildlife Service (USFWS), the California Resources Agency, California Department of Fish and Wildlife (CDFW), National Office of Oceanic and Atmospheric Administration, U.S. Army Corps of Engineers (Corps) and the Environmental Protection Agency (EPA), completed the largest wetland restoration west of the Mississippi. An ocean inlet restoring nearly 600-ac of degraded wetland habitat in the Bolsa Chica Lowlands was completed by adding to an existing fully functioning wetland habitat in the northwestern corridor of the City. This area is now known as the BCER, comprised of salt marsh, coastal dune, and coastal sage scrub communities.

Since the early 1980s, the County has designated the Huntington Mesa as the site for HWRP (formerly known as the Bolsa Chica Regional Park until October 1994). The HWRP was to provide a link between Huntington Central Park along the bluff of Huntington Beach Mesa to Pacific Coast Highway. The County, through its operating department OC Parks (OCP), currently holds title to approximately 34% of the land originally designated for HWRP. Signal Landmark, Thomas Oil & Gas and the City hold title to the remaining parcels. There is an Irrevocable Offer of Dedication (IOD) on the privately-owned property to the County identified on County records as Parcel 401 (40.360-ac) and Parcel 501 (10.804-ac) (Private Property). Said IOD was never accepted in any form by the County. Said Private Property shall remain in private ownership until the County accepts or assigns the IOD. The Conservancy is currently in discussions with the private landowner to acquire the Private Property. Figure 3 shows the areas of the HWRP that are currently owned by County and Private landowner.

The County’s current GDP for the HWRP (see Appendix H) calls for the restoration of native vegetation on the Huntington Mesa, the installation of a walk bridge to span the existing ravine, and the creation of a multi-use trail system that connects Huntington Beach Central Park to Bolsa Chica State Beach. Although construction of a walk bridge is not included as part of the restoration project, the plan establishes an appropriate setback in order to accommodate the footings of a bridge; this ensures that a future bridge will not impact the restored habitat. This project will also allow for the future implementation of improvements such as interpretive panels and benches. The GDP also calls for the establishment of an interpretive center to carry out educational programs for the public.

The Conservancy is pursuing to enter into an option agreement with the County to finance and construct the interpretive center on approximately ten (10)-ac within the HWRP. Once completed, the interpretive center is being proposed to be owned and maintained by the County and the Conservancy will have rights to carry out its programs and operate the facility.

The Restoration Project will provide significant benefits to regionally important biological resources, as well as a number of non-biological benefits including enhanced public access and open space viewshed preservation. It will also restore native habitat providing a beneficial buffer to existing wildlife. Removal of invasive species, particularly black mustard (Brassica nigra), Italian thistle (Carduus pycnocephalus), tocalote (Centaurea melitensis), common horehound (Marrubium vulgare), wild radish (Raphanus sativus), iceplant (Carpobrotus sp.) and sweet fennel (Foeniculum vulgare) would assist in the restoration of native habitat (see Appendix A: Vascular Plant Species Observed for a complete list of all nonnative and native species observed on site). The project will adhere to best practices widely used in the restoration science field, as well as to the requirements stipulated in the Measure M2 Environmental Mitigation Program Restoration Funding Guidelines (Appendix G).

The Project Site also contains native habitat (mapping of existing habitat types is presented in Appendix B), including riparian woodland consisting primarily of willow trees and CSS comprised of coyote bush (Bacharis pilularis), bladderpod (Isomeris arborea), Pomona locoweed (Astragalus pomonensis), western ragweed (Ambrosia psilostachya), and fascicled tarweed (Deinandra fasciculata). No sensitive species have been observed based on general biological surveys conducted in 1989, 1990, and 1991 as part of the 1997 General Development Plan Update and most recently in 2013 (Appendices A & B).

The primary aim of restoration within the Project Site will be the removal and control of invasive, nonnative plants across the entire restoration area, followed by the planting of native species to establish a more diverse habitat structure conducive to supporting an array of native plants and wildlife. Considerable focus will be placed on the creation of suitable habitat for sensitive species occurring, or with the potential to occur on-site, such as the least Bell’s vireo (Vireo bellii pusillus), coastal cactus wren (Campylorhynchus brunneicapillus cousei), coastal California gnatcatcher (Polioptila californica californica), and the Burrowing Owl (Athene cunicularia).

The project’s small riparian habitat extension may attract least Bell’s vireo, and the creation of cactus patches within grassland and coastal sage scrub habitat will offer new suitable habitat for coastal cactus wren and the California gnatcatcher. Grassland/forb habitat coupled with sage scrub and abundant ground squirrel holes will provide suitable foraging and wintering habitat for the burrowing owl. No direct impacts to owl habitat will occur as a result of restoration activities. No records exist of owl nesting in the area since 1990, and monthly Audubon surveys have occurred on site for the last 6 years with no record of nesting or wintering burrowing owls. The project site and surrounding areas of HWRP and the Bolsa Chica Ecological Preserve have been specifically surveyed for all bird life.

The Restoration Project will also restore native habitat providing a beneficial buffer to existing wildlife. Removal of invasive species, particularly black mustard (Brassica nigra), Italian thistle (Carduus pycnocephalus), tocalote (Centaurea melitensis), common horehound (Marrubium vulgare), wild radish (Raphanus sativus), iceplant (Carpobrotus sp.) and sweet fennel (Foeniculum vulgare) would assist in the restoration of native habitat (see Appendix A: Vascular Plant Species Observed for a complete list of all nonnative and native species observed on site). The project will adhere to best practices widely used in the restoration science field, as well as to the requirements stipulated in the Measure M2 Environmental Mitigation Program Restoration Funding Guidelines (Appendix G).

The Project Site is within the Santa Ana River Watershed within the HWRP. Apart from its high levels of invasive species, the Project Site also contains native habitat (mapping of existing habitat types is presented in Appendix B), including riparian woodland consisting primarily of willow trees and CSS comprised of coyote bush (Bacharis pilularis), bladderpod (Isomeris arborea), Pomona locoweed (Astragalus pomonensis), western ragweed (Ambrosia psilostachya), and fascicled tarweed (Deinandra fasciculata). No sensitive species have been observed based on general biological surveys conducted in 1989, 1990, and 1991 as part of the 1997 General Development Plan Update and most recently in 2013 (Appendices A & B).

Several permits must be obtained from a variety of local and state agencies before the Restoration Project can proceed. As far as the local government agencies are concerned, the Project Site lies wholly within the City of Huntington Beach jurisdiction. The Project Site is also within the Coastal Zone. The City of Huntington Beach has a certified Local Coastal Program (LCP) for the land under their jurisdiction and have issued a Coastal Development Permit (CDP) for Phase I developments including the restoration project. The County, on the other hand, does not have a certified LCP for the Bolsa Chica area. Therefore, the Coastal Commission retains CDP jurisdiction over the unincorporated area.

On the state level, the Restoration Project will most likely require a 1602 streambed alteration agreement from CDFW.

As the permittee, OCTA is responsible for ensuring the satisfactory completion of all commitments in this HRP necessary to obtain sign off from the wildlife agencies pursuant to Section 1.2.2 of the Restoration Funding Guidelines.

The Conservancy is responsible for obtaining all state and federal permits as well as complying with all state and federal laws required for implementation of this Restoration Project, including but not limited to requirements of the USFWS, Corps, CDFW, RWQCB, and California Coastal Commission (CCC). The Conservancy is responsible for meeting applicable performance standards. Long-term management of this project will be the responsibility of the Conservancy, in coordination with OCP.

OCP manages nearly 60,000-ac of parklands, including 27,000-ac of open space and wilderness. OCP encompasses regional, wilderness and historical facilities, as well as coastal areas throughout the County. OCP’s open space areas and programs are utilized by millions of residents and visitors each year.

1.1 LAND OWNERSHIP/LAND MANAGEMENT AND EXPERIENCE

The Restoration Project will include 9.52-ac of mixed ecotone and 0.17-ac of riparian expansion for a total of 9.69-ac (see Figure 4). OCP has committed to granting the Conservancy a license to access the property.

In consultation with California Department of Fish and Wildlife (CDFW) and OCP, the Conservancy will be responsible for the long-term maintenance of the Project Site. OCP will maintain ownership of HWRP and through a license, the Conservancy will be allowed to conduct and manage restoration activities on the Project Site. Portions not included in the Project Site will be managed by OCP.

General long-term maintenance of the Project Site will consist of trash and debris removal and weed control. The Project Site shall be kept free of trash and debris in perpetuity and removal shall occur quarterly. Inorganic debris that is deposited on Project Site will be removed during routine maintenance visits. Weed eradication and management will be conducted as necessary to minimize competition that could inhibit the growth of native species. As weeds become evident, they should be removed by hand or controlled with an appropriate herbicide as determined by a licensed qualified applicator. If any populations of the Measure M2 Covered Plant Species Southern tarplant (Centromadia parryi var. australis), intermediate mariposa lily (Calochortus weedii var. intermedius), and many-stemmed dudleya (Dudleya multicaulis)) are discovered they will be demarcated in the field, protected to avoid impacts, and promptly reported to OC Parks and entered into the California Natural Diversity Database (https://www.wildlife.ca.gov/Data/CNDDB).

Long-term management and maintenance will be implemented and overseen by the Conservancy. The Conservancy can utilize a large volunteer force to perform the necessary labor. Consequently, the Project Site will be managed and maintained effectively at low cost.

1.2 THE RESTORATION PLAN The Restoration Project will supplement and restore areas that are adjacent to ongoing restoration efforts at the BCER.

To expand restoration corridors that support the BCER and adjoining coastal habitats, the Conservancy proposes to restore the Project Site and make it available for public access through the Conservancy’s land agreement with the County. The goal of Restoration Project is to create swaths of native vegetation to increase plant diversity and thus expand foraging areas for wildlife that currently use the area. Existing native plants will be identified and retained in place, while native stock will be propagated and installed. Nonnative plants will be removed to allow for an additional variety of native vegetation to be put in their place. The Project Site supports habitat for birds of prey such as owls and northern harriers and terrestrial animals including coyotes, rabbits, snakes, lizards, opossums, raccoons, skunks, gophers, moles, and rodents. The Project Site is next to an active oil and gas field that contains salt marsh habitat interspersed between raised roads. This adjoining wetland habitat to the Project Site supports a variety of sensitive species including the State-endangered

Belding’s savannah sparrow (Passerculus sandwichensis beldingi), federally and State-endangered light-footed clapper rail (Rallus longirostris levipes) and California least tern (Sterna antillarum browni); the federally threatened western snowy plover (Charadrius alexandrines nivosus), and many Species of Special Concern. In addition, this project is expected to provide additional habitat for Measure M2 Covered Wildlife Species (least Bell’s vireo, coastal cactus wren, coastal California gnatcatcher, bobcat (Lynx rufus), pallid bat (Antrozous pallidus), long-eared bat (Myotis evotis), small-footed myotis (Myotis ciliolabrum), Yuma myotis (Myotis yumanensis), and big free-tailed bat (Nyctinomops macrotis)). The complete list of Measure M2 Covered Species is presented in Appendix D.

1.2.1 Ecological Benefits The removal of nonnative vegetation and the planting of a habitat-appropriate palette in all zones, including buffer zones and edge bluffs like Huntington Mesa, would support a correspondingly greater diversity of invertebrate species such as butterflies and other insects. These provide additional prey species for marsh birds and upland animals. Increased diversity and enhanced habitat for a stable upland wildlife community will be some of the ecological benefits from this Restoration Project.

The Restoration Project is intended to increase native vegetation coverage and improve habitat conditions for threatened and endangered plant and animal species that are native to the area according to preliminary biological surveys conducted in 1989, 1990, and 1991 as part of the 1997 General Development Plan Update and most recently in 2013 (Appendices A & B). A comprehensive survey, which will include sensitive species, will be conducted before work commences as outlined in Section 3.1 of this Restoration Plan. Our efforts will enhance foraging and breeding grounds for animals including coastal California gnatcatcher, least Bell’s vireo, silvery legless lizards (Anniella pulchra), and wandering skipper butterflies, and will target plants including southern tarplant.

Restores Impacted Habitats. With the exception of the adjacent playground, the Project Site is currently covered with nonnative plant species that do not allow optimal use by wildlife. The removal of nonnative plants and restoration of the Project Site to native CSS/grassland ecotone and the expansion of the existing riparian habitat will enhance the habitat value of this mesa and support the adjoining wetland. This Restoration Project proposes to restore CSS, CSS/native grassland ecotone, and riparian habitat types. These vegetative community types are among those that are expected to be impacted as a result of the OCTA M2 transportation improvement projects.

Restores Sensitive Habitats. This Restoration Project proposes to restore CSS, native grassland, and riparian habitat types. These habitat types are ranked as sensitive under the California Natural Diversity Database (CNDDB).

Benefits Habitat for Covered Species. This Restoration Project is expected to provide a net ecological benefit for the California gnatcatcher and coastal cactus wren by increasing breeding/foraging habitat and increasing connectivity to areas of suitable habitat found on Bolsa Mesa to the north and at Upper Newport Bay to the south. It is also anticipated that this Restoration Project will supplement existing open space and improve the quantity and quality of core habitat.

Enhances Conserved Lands. Restoration of the Project Site will support and expand already existing restoration at the lowlands in Bolsa Chica (see Figure 2).

2.0 HABITAT TYPES TO BE RESTORED

The Restoration Project involves creating and expanding native habitat around the onsite perennial stream in order to enhance ecosystem function and improve educational opportunities. Specifically, the HRP will create and expand CSS/native grassland ecotone and riparian habitat.

2.1 MIXED ECOTONE The Project Site is currently vegetated with ruderal, nonnative species (see Appendix A). The goal of the CSS restoration is to increase the habitat, educational, and aesthetic value of the Project Site by restoring 9.52-ac with native CSS and CSS/grassland ecotone species (refer to Figure 4). The mixed ecotone restoration sites are located on gentle slopes and flat mesas where Myford sandy loam soil exists. This same soil type exists at the nearby Brightwater habitat restoration site, which supports CSS. Depending upon factors such as slope, aspect, hydrology and soil type, the habitat may trend toward a more dense CSS shrub community, while in other areas the habitat may trend toward a more open CSS/grassland ecotone. Based on direction provided by USFWS, the distribution of habitat types will be determined by seeding and planting native species and documenting which species establish in a given area. This approach allows the environment to dictate the appropriate target community composition for a given area reducing the potential for restoration failure.

In its current state, the Project Site offers limited value to most wildlife species. Restoring native and herbaceous shrub species and interspersing patches of cacti throughout the Project Site will provide greater biodiversity within the mixed ecotone areas and provide foraging habitat for raptors and other native wildlife. This will provide additional benefits to target species such as coastal California Gnatcatcher and coastal cactus wren. Populations of CAGN exist in Newport Beach and the species has been recently observed nesting at the north end of the Bolsa Chica Wetlands. The Restoration Project’s location between these two nesting sites will enhance dispersal potential for the species and provide potential nesting and foraging habitat for cactus wrens.

2.2 RIPARIAN HABITAT There is currently 1.21-ac of existing riparian habitat within the Project Site (refer to Figure 4). The primary hydrology source supporting the riparian vegetation onsite is freshwater nuisance runoff from the golf course and housing development on the south side of Seapoint Avenue. The Project Site currently contains high-quality riparian vegetation dominated by native willow species. The objective is to improve and expand the existing riparian habitat by approximately 0.17-ac through the removal of invasive nonnative vegetation, and installation of a native plant palette. Proposed actions include:

• Removal of nonnative vegetation along the outside edges and within existing willow scrub; and

• Installation of riparian vegetation (primarily those native species commonly found within willow scrub) around the perimeter of the existing native habitat; and • Installation of mulefat as a transition from the willows to a mixed ecotone of CSS and native grassland on the Mesa.

Figure 5: Jurisdictional Areas

The proposed plan is to increase the riparian willow scrub by creating a buffer of 10ft of willow species along the edges of the existing riparian zone. This 10ft zone will transition into baccharis scrub for another 20 - 30ft, which will transition into CSS on the mesa. These 10ft and 30ft habitat zones will need initial invasive removal and continued removal and monitoring (up to 2-3yrs) after planting to rid the area of annual invasive seed banks.

2.3 SOUTHERN TARPLANT Although there are no known occurrences of southern tarplant on site, it has the highest likelihood of occurring on site out of the three Measure M2 Covered Plant Species. In addition, it will be seeded on site as part of the restoration effort. Surveys for southern tarplant and the other Measure M2 Covered Plant Species will occur prior to Restoration Project initiation (see Section 3.0). While our most recent survey of the area did not yield any observations of southern tarplant, any emerging individual plants observed later will be preserved as part of the Restoration Project to ensure the growth and success of any populations of this species present in the Project Site. In addition, southern tarplant seeds will be collected from well-established populations in other Bolsa Chica locations and hand- seeded in suitable areas. The ideal location(s) will be flat and subject to seasonally, but brief, wet conditions, such as along dirt roads or in very shallow depressions. Myford sandy loam soil exists at this site, which also occurs at the nearby Brightwater habitat restoration site, which supports Southern Tarplant in some of the flats and depressions. Management and maintenance will include nonnative vegetation removal to reduce competition from other species and to facilitate adaptive management strategies (e.g., supplemental seeding) to benefit the southern tarplant. The development of populations will be monitored by counting or estimating individual tarplants; however, no specific performance criteria will be required for this species.

3.0 RESTORATION AND EDUCATION ACTIVITIES

The Conservancy will coordinate and oversee all aspects of restoration. The Conservancy will provide staff and volunteer labor. While increasing habitat values at the Project Site is the primary goal, enhancement of the area’s educational value is a secondary benefit. Engaging the community and leveraging local partners in carrying out components of the proposed restoration will help expand the public’s understanding of coastal ecology, native plant restoration, and environmental conservation.

3.1 SITE ASSESSMENT A comprehensive site assessment will be completed by qualified individuals prior to initiating restoration work on the Restoration Project, and will be submitted to OCP and subject to review and approval by OCTA and the Wildlife Agencies. The site assessment will (1) identify the basic opportunities and constraints for successful restoration and (2) establish existing or baseline conditions prior to initiation of restoration activities. The latter will allow for a comparison of pre- and post-restoration conditions and thus, a measure of the overall success of the restoration effort. The site assessment will utilize a combination of existing data and surveys, including but not limited to technical reports, plant and animal surveys, vegetation and species mapping, field sampling, aerial photography, photos of existing conditions, land use maps, USEPA 303(d) listings, and historic records. The site assessment will document:

• Existing or historic land uses within and adjacent to the Project Site (including easements) • Potential for cultural resources issues • Project Site access and proximity to water sources • Existing and historic habitat conditions on and adjacent to the Project Site • A general biological survey • A survey of sensitive flora and fauna on the Project Site • Sensitive species mapping (distribution) on or near the Project Site prior to and following nonnative vegetation removal • Invasive species mapping (species specific, abundance, acreage, and distribution/map with polygons) on the Project Site • Soil suitability, as appropriate to the specific restoration effort • Topography • Compatibility with adjacent land uses and watershed management plans • Reference sites for alternative success criteria, as applicable (this should also include a delineation of jurisdictional waters and a functional assessment)

The result of the site assessment will be compiled into a report (see appendix I). The report will be submitted to OCP, OCTA and the Wildlife Agencies to allow the agencies to review the results and recommend any changes to the performance criteria and restoration plan. The recommendations will be incorporated into the restoration plan and then it shall be finalized.

3.2 SITE PREPARATION

Site preparation for the expansion of the riparian zone will include hand removal of invasive weeds in the current ruderal land surrounding the existing riparian habitat. Removal of invasives in the existing riparian habitat will also be necessary. This area will need to be weeded initially and continually for up to 2-3 years to remove the annual invasive species seed bank. The Conservancy does not plan to apply any herbicide to this area due to its close proximity to the waterway.

Hand removal is essential at the CSS/grassland ecotone restoration sites because natives are interspersed with nonnative plants. Areas that have become overly compacted through repeated use by vehicles, public use (e.g., abandoned ranch roads and trails), or grading activities will be ripped in consultation with the CDFW for areas in the BCER and OCP for restoration areas in its jurisdiction and under the Conservancy’s lease agreement. There will be removal of trash and debris and completion of other tasks necessary to prepare the area for planting. The Conservancy will collaborate with CDFW and OCP to evaluate the Project Site relative to the need for a “grow/kill” program to reduce nonnative annual grasses and forbs prior to planting. Existing native shrubs will be flagged and preserved to keep soil disturbance minimized. The Conservancy will collaborate with OCP and the Wildlife Agencies to integrate a network of multi-use nature trails through the CSS/grassland ecotone habitat consistent with the General Development Plan for recreational and educational use. The preliminary layout of the proposed nature trails, which to date has been coordinated with OCP, is depicted on Figure 4. The Wildlife Agencies will also be consulted with for the siting of trails through the Restoration Project site.

3.2.1 Cultural Resources

Due to the existence of cultural sites in the area of the restoration, this HRP addresses cultural resource protection by applying planting and seeding techniques in conjunction with the selection of plant species that have low growing stems with similar root systems for use within areas where cultural resources may be present. Also, the Conservancy will consult with Native American representatives prior to the start of the restoration regarding the plant palette and planting techniques. If necessary, the Conservancy will retain a qualified Native American to monitor planting activities particularly when digging holes for sign posts and similar types of manual excavation. Please refer to Appendix J for HWRP Cultural Resource Management Plan for recommend avoidance measures.

3.2.2 Grow/Kill Program In the event that a grow/kill program is required, it will be completed during site preparation, which will occur in Year 1. Most likely, two grow/kill cycles will be necessary, which will take about two months to complete. Ideally, this will occur in the Fall before planting and seeding occurs. Procedures for this program are as follows:

• Project Site is irrigated to encourage growth of non-native seed bank. A connection to the existing water supply found at the adjacent playground park will be established for this and other water needs. • Established native shrubs will be covered to prevent contact with herbicides. • Vegetation eradicated with herbicides. Only Rodeo, an EPA approved, glyphosate-based systemic herbicide, may be used, unless CDFW or OCP mandates a specific herbicide. No preemergent herbicides may be used. • Procedure is repeated once more for a total of two cycles. • Planting and seeding will only occur after this program is completed.

3.3 CONTAINER PLANTS The Project Site will be planted using nursery stock propagated from seeds and cuttings collected in coastal Orange County, within 15 mi of the Project Site. Planting activities shall take place between October and January to take advantage of natural rainfall and to reduce erosion caused by bare graded areas. The mix of species will be adjusted for local conditions within each restoration site. Restoration plant palettes for each habitat type are included in Appendix E.

3.4 CUTTINGS Willow and mulefat cuttings will be collected by the Bolsa Chica Conservancy within ten (10) mi of the restoration site and will be planted individually as well as bundled in wattles. All willow and mulefat cuttings will be thoroughly inspected for evidence of Polyphagous Shot Hole Borer (PSHB) prior to collection.

3.5 SEED INTRODUCTION In addition to container plants, the Project Site (with the exception of the riparian restoration site, which will likely include or be wholly limited to hand seeding) will be seeded via either the hydroseed method or land imprinting, a no-till method that has been successful in the restoration of CSS habitat at San Onofre State Beach. Seed and soil mychorrizae will be applied between October and the end of December to take advantage of natural rainfall and to reduce erosion caused by bare graded areas. Restoration seed mixes for each habitat type are included in Appendix E.

3.6 TEMPORARY IRRIGATION As part of the grow/kill program, an irrigation system to be designed and built by the Conservancy will be installed following initial clearing of nonnative vegetation to provide adequate irrigation to facilitate germination of weed seeds in the soil seed bank. Temporary irrigation will also be used throughout the Project Site to facilitate plant establishment. Water will be obtained from municipal sources. The Conservancy will seek technical support in designing a temporary above grade irrigation system and will submit the design to CDFW, USFWS, and OCP for approval. After obtaining approval, the Conservancy will install the irrigation system and be responsible for removal of the system once the plants have become established. Temporary irrigation will be discontinued approximately two years before Restoration Project completion.

3.7 MAINTENANCE Maintenance will occur over the life of the 5-year establishment period. Maintenance of the Project Site must be performed in accordance with the following specifications until the performance standards are achieved (refer to Section 4.0 for a discussion of the performance criteria for each habitat type). Maintenance will include erosion control, weeding, herbivore control, and watering as necessary.

3.7.1 Erosion Control In the case of heavy rainfall, vegetative and nonvegetative erosion and sediment control measures (i.e., live wattles, silt fencing, sandbags, coir wattles, jute netting) will be used. Fiber rolls with plastic netting will not be used as they pose a wildlife entanglement hazard.

The Conservancy shall be responsible for all erosion and sediment control required during the entire term of the contract. Erosion and sediment control shall include, but not be limited to: (1) continuation of vegetative and non-vegetative erosion and sediment control, as necessary; (2) repair of damaged plants, rutting, and washouts; and (3) removal of downstream silt and mud. This will include slowing the velocity of and dispersing concentrated water entering and exiting the Project Site. Coir wattles will be placed at appropriate intervals throughout the Project Site. For example, steeper areas may require wattles to be placed at 10 ft intervals, while areas that are gently sloped may only require wattles every 30 ft. All wattles will be installed along slope contours in accordance with the manufacturer’s specifications, and spacing will be determined by the Conservancy’s Restoration Ecologist. The Conservancy will secure all necessary wattle approvals from CDFW, USFWS and OCP prior to purchase and/or installation. All erosion control measures will be in accordance with National Pollution Discharge Elimination System (NPDES) regulations.

3.7.2 Weeding In order to help establish the developing communities, nonnative weeds shall be removed from the Project Site to reduce the amount of competition for natural resources, including water, nutrients, and sunlight. The amount of weeding required will be determined by the amount of weed seed in the soil, weather conditions, as well as the diligence and persistence used in removing the weeds before they produce more seed, thereby reducing the weed seed bank.

With the exception of those weed species that cannot be eradicated through manual removal, weeds present shall be removed manually. Herbicide will only be permitted within the restoration areas with the written authorization of the Restoration Ecologist and the approval of CDFW and OCP. Only Rodeo, an EPA approved, glyphosate-based systemic herbicide, may be used, unless CDFW or OCP mandates a specific herbicide. No preemergent herbicides may be used. No weed whipping or string- line trimmers shall be permitted within the Project Site without the written authorization of the Restoration Ecologist. Special care must be taken to prevent damage to native plants. Native plants intentionally or unintentionally damaged shall be replaced as needed in the form of container plants during the next growing season in order to attain the performance standards. All nonnative vegetative debris accumulated as a result of weed removal activities shall be legally disposed of off-site.

3.7.3 Herbivore Control The control of damage to the restoration efforts by insects and herbivores shall be the responsibility of the Conservancy. The Restoration Ecologist shall implement control measures at the earliest sign of damage, which may require fencing or caging of plant materials.

3.7.4 Prevention of Public Trespass To prevent the public from encroaching on the Project Site, cable and thimble-eye fencing will be installed around the perimeter of the Project Site. Signage will be placed on the fencing at regular intervals to indicate that the site is closed to the public for restoration. These activities will be coordinated with OCP prior to and during implementation. Fencing and signage will be removed once performance criteria are achieved.

3.8 MEASURES TO MINIMIZE IMPACTS TO SENSITIVE SPECIES Enhancement activities within the Project Site are aimed at restoring habitat for native species, including sensitive species, and will be conducted in a manner that is consistent with the existing regulatory framework for protected species. Potential regulatory constraints that will be adhered to include the following:

• Endangered Species Act – Federal and California Endangered Species Acts prohibit the “take” of species listed as threatened or endangered but include provisions for addressing listed species. • Federal Migratory Bird Treaty Act – makes it illegal to kill, take, or otherwise harm migratory birds, nests, eggs, etc. Covers over 800 species and is defined as those which live, breed, or migrate within or across international borders. • California Fish and Game Code 3513 – protects all non-game migratory birds, essentially all native birds.

3.8.1 Measures to Limit Impacts to Nesting Birds Proposed Restoration Project activities (including, but not limited to, staging and disturbances to native and nonnative vegetation, structures, and substrates) should occur outside of the avian breeding season to the maximum extent practicable to avoid disturbance to breeding birds or destruction of the nest or eggs. For this Restoration Project, the height of the nesting bird season is defined as March 15 – August 15 for riparian habitat and February 15 - June 30 for upland habitat.

If avoidance of the avian breeding season is not feasible, 3-5 days prior to the initiation of Restoration Project activities, a qualified avian biologist will conduct a nesting bird survey in the suitable nesting habitat that is to be directly or indirectly disturbed. The following buffers will be implemented based on the intensity of the restoration activities- low: e.g., hand weeding or herbicide application (50 ft or 100 ft for raptors and State and federally listed species); medium: e.g., weed whipping (100 feet or 200 feet for raptors and State and federally listed species); high: e.g., grading or other large mechanized equipment (150 feet or 300 feet for raptors and State and federally listed species).

If a native active bird nest is found, the following steps will be implemented to avoid and minimize impacts to the nest:

a) When the biologist finds the nest, an assessment of the nest-specific buffer will be evaluated based on topography, vegetation, species, individual bird behavior, and the level of potential disturbance associated with the proposed activities. If a larger avoidance buffer is required, it would be established based on those criteria. If a smaller buffer would be adequate, the qualified avian biologist will identify the appropriate buffer distances for raptors and non- raptors and provide the Wildlife Agencies a site-specific Nesting Bird Protection Plan prior to implementation.

b) Flagged stakes will be used to mark the edges of the avoidance buffer where it overlaps restoration work areas. This area shall not be disturbed until the nest becomes inactive or the young have fully fledged (independent of the nest and adults).

c) A survey and nest tracking log shall be maintained for each nest, which would include surveyor, date, time, weather, species, dates, nest substrate, nest height, nest stage, nest outcome, GPS coordinates, and other pertinent observations. The nest log would be submitted to OCTA at the end of each week.

d) Restoration personnel, including all contractors and/or volunteers working on Project Site, should be instructed on the meaning of the staked areas, and how this is ensuring compliance with applicable state and federal laws pertaining to the protection of native bird nests.

The restoration task leader will ensure that all restoration activities occur outside the demarcated buffer and that the flagging/stakes are readily visible and maintained. The nest status should be checked approximately weekly unless the nest is readily visible from a distance away and can be updated without approach. The restoration task leader will send weekly monitoring reports to OCTA for restoration activities that occur during the nesting bird season, which will also include the nesting bird log. OCTA shall be contacted immediately if Restoration Project activities result in impacts or failure of a nest. Within 48 hours of damage to an active nest or eggs or observed death or injury of birds protected under State law or the MBTA, OCTA will notify the Wildlife Agencies.

3.8.2 Measures to Limit Impacts to Sensitive Plants If any sensitive plants are encountered at any point during the Restoration Project these individuals will be flagged in order to ensure avoidance during site preparation and other enhancement activities. In all locations where sensitive plants species occur, the Restoration Ecologist will oversee implementation, including any heavy equipment, to help guide workers around sensitive resources.

3.8.3 Measures to Limit Impacts to Existing Freshwater Creek The Conservancy will use best management practices to prevent any discharge or erosion from entering the existing freshwater creek located within the Project Site. Erosion control efforts are outlined in Section 3.7.1. No herbicides will be used in the riparian habitat in order to limit chemical discharge in to the creek.

4.0 PERFORMANCE CRITERIA

The restoration of the Project Site will be considered successful when all of the following criteria are achieved:

4.1.1 Mixed Ecotone Sites: • Restoration plantings shall attain the following: Year Native Scrub Cover (%) Survival of Container Plantings (%) 1 25 80 2 35 90 3 45 -- 4 55 -- 5 75 --

• Years 1, 2, and 3will have less than 10 percent cover by non-native species and years 4 and 5 will have less than 5 percent cover by non-native species, and 0 percent cover by non-native invasives (Cal-IPC List 1-A species). Discovery of Cal-IPC List 1-A species will be promptly reported to OC Parks. • The Project Site will attain 15% native cactus cover by year 5. • In order to ensure an adequate amount of native species diversity, the Project Site shall have 90 percent of the native plant diversity of an appropriate reference site. • The Project Site will not be eligible for agency acceptance until it has gone without supplemental irrigation for a period of 2 years.

4.1.2 Riparian Restoration Sites: • Within the enhancement areas, the Restoration Project shall attain the following: Year Perennial Riparian Cover (%) Survival of Container Plantings (%) 1 25 80 2 35 90 3 45 -- 4 55 -- 5 75 --

• Evidence that the Project Site is sustainable by showing signs of regeneration (progeny and new growth), healthy plants, a low mortality rate, and resistance to invasive weeds (less than 10 percent cover by nonnative herbaceous invasive weeds, less than 5 percent cover by nonnative species and 0 percent cover of non-native invasives (Cal-IPC List 1-A species)). Discovery of Cal-IPC list 1-A species will be promptly reported to OC Parks. • The Project Site will not be eligible for agency approval until it has gone without supplemental irrigation for a period of 2 years.

5.0 MONITORING

To ensure that the Project Site is in compliance with the HRP, the Restoration Plan requires that the Project Site be monitored until the performance standards have been met. The following tasks are required:

• Initial inspection during the 120-day establishment period. Biweekly site visits will be conducted to examine the restoration areas and evaluate the established success of the seeding and container plants. • Following the 120-day establishment period, monthly inspections of the Project Site will be conducted to assess the condition of the restoration areas and to determine maintenance activities as necessary. However, more frequent Project Site visits may be necessary if any unforeseen problems should occur. • The Project Site will be visited on an annual basis to evaluate the site relative to the performance standards until the performance standards are met.

To ensure that the Project Site is in compliance with this HRP, the Project Site will be evaluated annually for 5 years using the performance criteria discussed in Section 4.0. The Project Site will also be inspected on a more frequent basis. The Project Site shall be eligible for resource agency approval 3 years after installation if the 5-year performance criteria have been achieved and the site has been without irrigation for two years. If the performance criteria are achieved before 5 years, with agency acceptance, annual monitoring may be discontinued.

Annual monitoring will include the following tasks (summary in Table A, Section 5.0):

• Site inspections for survival, appearance, function, wildlife usage, and general compliance will be completed until the performance standards are met. • Plants will be inspected for Polyphagous Shot Hole Borer (PSHB). • A survey will be conducted in the spring of each year. Qualitative data will be collected on the native and nonnative vegetation cover, species composition, survival, appearance, and function of the plant community. In addition to qualitative data, quantitative data on native and nonnative vegetation cover and species composition will be collected by performing at least 10 50 ft, point- intercept transect surveys. All wildlife species present on Project Site shall be recorded and photos will be taken at established photopoints. An additional survey will be conducted in the summer of each year to count or estimate numbers of southern tarplant plants during the flowering stage with supplementation of surveys with Relevé plots to capture forb diversity. • As part of the annual surveys, the Conservancy will prepare field memorandums with the support of staff ecologists and/or Contractor ecologists. The field memorandums will record general ecological observations and make maintenance recommendations, and copies will be sent to the Conservancy, OCTA and OCP. Any sensitive plant species will be reported to OC Parks.

• If any sensitive species are observed on or in proximity to the Project Site during project surveys, Conservancy staff or the Restoration Ecologist will submit CNDDB forms and maps to the Biogeographic Data Branch within 5 working days of the sightings and will provide the regional CDFW office with copies of the CNDDB forms and survey maps. Conservancy staff will also notify OCP. • Cal-IPC List 1-A non-native invasive species will be promptly reported to OC Parks.

Conservancy staff or the Restoration Ecologist will monitor the progress of the Project Site. Monitoring will be performed by experienced botanists or biologists who are qualified to assess the performance of the restoration effort and to recommend corrective measures as needed.

Following each monitoring visit, a monitoring report shall be submitted to OCTA, OCP and the Wildlife Agencies. The monitoring reports shall provide a record of the field activities conducted during the site visit, the status of the Project Site during the visit, any problems encountered, and recommendations for future actions. Monitoring reports will be submitted according to the monitoring visit schedule. Reports will be submitted within one month after each monitoring visit.

6.1 ANNUAL MONITORING REPORTS

Annual reports will be submitted to OCTA for review and approval by January 15 of each year beginning after the plants have been in the ground for an entire spring and summer and continuing until the performance criteria described in Section 4.0 are achieved. OCTA will be responsible for submitting annual reports by February 1st to the Wildlife Agencies, CCC, and OCP. Permittee will then request a final review of the Project Site and written confirmation of success from CDFW. Conservancy will next conduct a final project walk-thru with OCP upon receipt of written confirmation of success from CDFW. The reports will also identify any corrective actions necessary to achieve the performance standards. These reports will be submitted by the Conservancy to OCTA and OC Parks for review and submittal to CDFW, USFWS, and CCC. A summary of the monitoring and reporting schedule is presented in Table A.

The annual monitoring reports will include the following:

• A summary of the monitoring visits throughout the year which will include both the schedule of the visits and activities conducted during each visit. • A description of the restoration activities, including revegetation and exotic species removal, and when these activities were conducted. • Description of natural recruitment by native species on the Project Site. • A summary of the qualitative assessment and the quantitative data collected in reference to the performance criteria. • Weather conditions and response of restoration areas and/or implementation of restoration activities to changes in weather conditions. • Any observations of wildlife within the restoration areas, including state or federally-listed species, California species of special concern, or their sign within the Project Site. • A table of general wildlife species observed using the Project Site, including reptiles, birds, mammals, and invertebrates based on casual observations of those animals, their tracks, scat or other signs. • All plantings will be inspected for Polyphagous Shot Hole Borer (PSHB). • Sensitive species will be reported to OC Parks. • Any Cal-IPC List 1-A non-native invasive species will be promptly reported to OC Parks.

• Discussion of any problems encountered during restoration and the methods used to remediate those problems, including weed control, trash removal, alteration of irrigation schedule, etc.; • Photo documentation at specified locations; and • A summary of replacement plantings and additional seeding events that may need to take place

6.2 FINAL REPORT

A final monitoring report will be submitted to OCTA and OCP upon completion of the 5-year monitoring effort or once the performance criteria are achieved. The final report will be a complete record of all of the maintenance and monitoring activities and present a summary of the results of the Restoration Project through all monitoring years. Qualitative and quantitative results shall be presented and accompanied by photo documentation. The final report shall also include recommendations in terms of Best Management Practices for the long-term management of the Project Site, although the Conservancy will maintain the site in perpetuity as discussed in Section 7.0.

7.0 LONG-TERM MAINTENANCE

Following agency approval that performance criteria have been achieved, Bolsa Chica Conservancy will be responsible for long-term maintenance of the Project Site in perpetuity. In the event the Conservancy ceases to exist, this responsibility shall pass to OCP, its successors or assigns. Maintenance will consist of monthly surveys of the Project Site, identification of any issues to be addressed, and implementation of management action to resolve those issues in order maintain site integrity. This includes but is not limited to: • Trash and debris removal • Nonnative plant removal • Pathogen and insect infestation remediation in coordination with OCP • Herbivory remediation • Upland erosion remediation (not including riparian habitat) • Trail maintenance • Fencing maintenance • Remediation of interpretive sign, trail, fencing, or habitat vandalism

During the monthly surveys, if the following issues are observed, the Conservancy will immediately notify OCP. • Public health and safety concerns • Homeless encampments • Signs of unlawful entry (ex. 4WD vehicles) • Unlawful dumping of debris or hazardous materials

The Bolsa Chica Conservancy is a 25-year-old organization with ever-increasing budget and staffing levels. Funding base comes from membership, program participation donations, fund raisers, and grants. The Conservancy has a history of successful restoration of foredune, coastal sage scrub, and tidal wetland habitats in Bolsa Chica Ecological Reserve. Employees will utilize student interns through the year, and will make patrols of the Harriett Wieder project site to monitor and record, and report to Orange County Parks any deficiencies. Since early 2017, the property to the North of the project site is entirely owned by the Bolsa Chica Conservancy, and the need for increased visits has grown for the project and other land management concerns.
