Section 5 of the Draft NCCP (page D-1) E. Public Comments (page E-1) BACKGROUND AND DISCUSSION: In the spring of 2017, the City Council appointed Mayor Pro Tem Jerry Duhovic and Council Member Ken Dyda to a subcommittee to identify possible solutions or strategies to remediate the Portuguese Bend (PB) Landslide. This subcommittee was formed to begin a collaborative process with community stakeholders and (possibly) with professional experts. 1 In order to provide a forum for stakeholder involvement, the City Council convened a Committee of concerned residents to chart a path towards achieving stabilization of the PB Landslide. The Committee identified one of its top priorities as "a complete characterization of the hydrology of the area." Public Workshops on Remediating the PB Landslide A series of four (4) public workshops were held to elicit the best ideas of the community, and to seek input on goals and possible solutions to remediate the PB Landslide. The workshops were held in the evenings (6:00 PM) at Hesse Park, and public notification was provided via the City's website, the "Breaking News" listserv, and the City's Nextdoor and Facebook pages. Approximately 20 to 30 residents attended these workshops and participated in the process. Each of the workshops focused on a specific topic as summarized below (summary notes from each workshop are include as Attachment C): • Public Workshop No. 1 held on June 1, 2017 - Identifying Goals At this first community workshop, a short introduction was provided by Council Member Dyda and Mayor Pro Tem Duhovic, who outlined the process. During this workshop, the following three (3) major goals were identified, along with potential solutions relating to the landslide (also referred to as "landflow") that might need to be considered in the series of meetings to follow. 1. Control slide and control costs: • Decrease the cost of ongoing road repair • Decrease resident inconvenience • Decrease cost of slowing slide • Home stabilization • Eliminate the danger of the City being "cut in 2" by the loss of the Palos Verdes Drive South • Retain Palos Verdes Drive South • Restore ecology/geology (ocean & land) • Preserve ocean life/tide pools 2. Legal protection • Explore possible geological hazard abatement district to protect City from costly and hazard -related damages • Avoid a liability situation similar to Palos Verdes Estates landslide • Understand legal protection upfront 3. Protect the integrity of the nature preserve • Oceanic and Land Ecosystems 2 At this first workshop, the desired result was to structure a design -build Request for Proposals (RFP) to solicit Federal funding for contracting companies to provide cost vs. options for success in their responses, as well as the following: 1. Project study report by professional experts; 2. Create community consensus • Public Workshop No. 2 held on June 20, 2017 — Surface and Subsurface Water Runoff This public workshop focused on eliciting community input on major potential solutions and actions to intercept water runoff from permeating the ground. The discussion that ensued at this workshop was wide-ranging, and emphasized on the following: 1. The need to fully understand the hydrology of the watershed within the Portuguese Bend area; 2. The need to re-establish and maintain an effective storm water control system; 3. The importance of capturing and controlling water runoff before it permeates into the PB Landslide; and, 4. To minimize impacts to the Palos Verdes Nature Preserve The attendees at this workshop listed their objectives and voted on what was of greatest importance to them, as reflected in the attached summary notes. • Public Workshop No. 3 held on June 29, 2017 - Surf -zone erosion This public workshop began with an introduction by Councilmember Dyda and there was a brief power point presentation given by Ray Mathys. The presentation centered on building a buttress at the toe of the slide that would eventually, over time, stop the movement, thereby eliminating the sediment from entering the ocean. Additionally, there was discussion regarding wave action and reef barriers. Consensus of the participating public focused on the following: 1. Hiring competent engineers to implement recommendations; 2. Early communication with relevant regulatory agencies (e.g., Coastal Commission) regarding any remediation plans that impacts the City's Coastal Zone; 3. Use of road maintenance funds to underwrite the necessary technical work needed to remediate the PB Landslide; and, 4. Conduct an assessment of the environmental impacts that remediation work would have on the Palos Verdes Nature Preserve and ocean ecology • Public Workshop No. 4 held on July 6, 2017 — Ground Water. 9 This public workshop focused on major actions that could be considered as a means of addressing the PB Landslide. As with previous workshops, the public consensus focused on the following: 1. Understanding the hydrology of the PB Landslide; 2. Understanding the occurrence of groundwater as it relates to the movement of the PB Landslide; and, 3. Understanding and completing previous work of surface drainage Pursuant to these workshops, the City Council subcommittee and attendees identified that hiring a competent coastal engineer to perform a landslide remediation feasibility study with a full hydrology study of the area was an important next step because expert testimony and data are essential to moving on to the next step. A number of studies of the PB Landslide have been conducted over the years, but none recently. Those studies have generally indicated that slope stability could potentially be achieved through some combination of surface water capture and infiltration control, groundwater extraction/dewatering, mass regrading, reinforcement of the landslide toe, and shoreline erosion control. The City desires to develop a comprehensive program that will ultimately result in stabilizing the extensive landslide complex that exists in the Portuguese Bend area. The program that the City envisions will use information presently available to characterize, as completely as possible, the hydrology of the landslide area. Using this characterization, and at the direction of the City Council subcommittee and the public in attendance at this past summer's public workshops, Staff was directed to identify a consultant that had the combination of specialized skills needed to assist the City with remediating the PB Landslide. A proposal was requested from the firm Daniel B. Stephens & Associates (DBS&A), Inc. because they have expert staff and are highly qualified. Additionally, their staff had attended the workshops prior to the engagement just to familiarize themselves with the project. The DBS&A team offers a wealth of expertise and experience in conducting hydrologic, geological, and engineering investigations and landslide stabilization projects. They specifically built a team to provide the City with unique expertise in groundwater hydrology, surface water hydrology, engineering geology, and geotechnical engineering. The team has high-level technical credentials and credibility. With this strong academic and applied science background, their staff has the ability to make intelligent and expeditious decisions in the field and prepare clear and defensible reports of findings and recommendations. The direction from the Subcommittee and City Council was to develop practical, workable solutions to remediate the PB landslide complex that will be well-received by the public and in the possible funding application review process. Because sources impacting the PB Landslide extend beyond the City limits, the direction given to Staff and DBS&A was to create a plan without being restrained by jurisdictional boundaries. El PB Landslide Remediation Draft Feasibility Study The specific purpose of the Draft Feasibility Study is to identify and select a conceptual solution that will accomplish the following overall project goals: • Provide the geotechnical conditions that reduce the risk of damage to public and private property and would allow for the significant improvement of roadway infrastructure, safety, and stability. • Significantly reduce human health risk and improve safety in the City. • Significantly reduce sediment deposition into the Pacific Ocean that is causing unacceptable turbidity in the coastal and marine environment. • Make all reasonable efforts to identify a remedy which will be consistent with the NCCP and the Habitat Conservation Plan. An Administrative Draft Feasibility Study (FS) was completed in December 2017 and delivered to City Staff and the City Council subcommittee for review and input prior to being released to the public. On December 22, 2017, the Draft FS was placed on the City's website for community review (Attachment A), and a listsery message was issued announcing its availability and City Council's review of the document at tonight's meeting. The Draft Feasibility Study document follows the following format: Section 1: Introduction, which includes project background, history, project purpose, projection area definition, and community involvement. Section 2: Summary of the relevant previous work. Section 3: Physical characteristics of the project area, which includes topography, watershed hydrology, soils, geology, ground water, and landslide characteristics. Section 4: Infrastructure concerns and appropriate environmental requirements, remedial action objectives, broad classes of available technologies for response actions to control movement of the Portuguese Bend Landslide Complex (PBLC), detail discussion and analysis (presenting pros and cons) and finally preferred alternatives including an estimate of the cost for implementation of the selected remedy. The Draft FS identifies the following general actions that could potentially remediate the landslide: • Stormwater control • Subsurface dewatering • Engineered slope stabilization measures • Eliminate septic system discharge 5 To achieve these actions, the Draft FS considered common technologies available in the industry to remediate the PB Landslide, including the following (a detailed description can be found on Page 52 of the Draft FS): • Repair Existing Corrugated Piping Systems • Install Concrete Swales • Install Linear and Channel Systems • Seal Surface Fractures • Groundwater Extraction Pits • Groundwater Extraction Wells • Directional Subsurface Drains • Buttressing • Mechanically Stabilized Earth Wall • Drilled Piers • Centralized Sewer System • Surf erosion/off-shore breakwater The above list of technologies were screened and narrowed based on known conditions. The following technology alternatives were retained for more detailed evaluation: • Concrete Channels • Flexible Liner System and Components • Seal Surface Fractures • Groundwater Extraction Wells • Directional Subsurface Drains • Centralized Sewer System The evaluation criteria used to analyze the above alternative technologies was based on the following: • Overall protection of human health and environment • Compliance with applicable environmental rules and regulations • Long-term Effectiveness and Permanence • Short-term Effectiveness • Implement ability • Cost • State and Community Acceptance. Based on the evaluation and discussions presented in the body of the study, the following approach was selected as the Consultant's preferred alternative remedy. The proposed remedies that comprise the preferred alternative were identified based on the assumption of the effects/impacts of a "100 year storm event": 0 Seal surface fractures. • Directional subsurface drains. • Surface drainage control using a flexible liner system and components. • Ground water extraction wells. • Centralized sewer system. Staff seeks the City Council's input on the Consultant's recommended landslide remediation measures prior to finalization of the Draft Feasibility Study for adoption. Consistency with the Natural Communities Conservation Plan/Habitat Conservation Plan On October 2, 2017, the City Council held a workshop to receive a status report on the Natural Communities Conservation Plan (NCCP) and Habitat Conservation Plan (HCP) That evening, the City Council was informed that, because of the relatively high concentration of federally protected coastal sage scrub habitat in the City, and the growing intensity of development pressures on these areas combined with the ability to streamline the entitlement process for City projects (i.e., storm drain, road repairs, and landslide remediation projects), in 1996, the City entered into a Planning Agreement to develop an NCCP/HCP proposal that will encompass the entire City with the California Department of Fish and Wildlife (CDFW) and the U.S. Fish and Wildlife Service (USFWS), referred to as the "Wildlife Agencies." It was also reported that an important objective of the NCCP/HCP is for the City to obtain State and Federal Permits from the Wildlife Agencies for Covered Activities, which include City and private projects. At that workshop, it was reported that over the past year, the City Council Subcommittee has been exploring methods to remediate the landslide at Portuguese Bend, and that the feasibility study was being prepared within the parameters of the NCCP/HCP. Staff specifically reported that Section 5 of the NCCP/HCP (Attachment D) identifies covered activities that are permitted to occur in the City, particularly landslide remediation projects, as part of the City's "take" permit for any potential loss of Coastal Sage Scrub (CSS) and Grasslands, as called out in Table 5.1 as follows: 7 City Project Name Total Habitat Loss (Acres) CSS Grassland Habitat Loss In Preserve (Acres) CSS Grassland 1.

It is anticipated that new wells will be installed by the City in the future in or near areas of existing CSS habitat and grassland throughout landslide areas. It is estimated a maximum of 2.5 acres of CSS and 2.5 acres of non-native grassland will be impacted in the Preserve. A point location for one gnatcatcher occurs in the project vicinity. • 5.2.3 Landslide Abatement Measures When and where required, landslide abatement activities within the Preserve and throughout the City are sometimes necessary by the City or other public agencies to safeguard existing roads, trails and drainage systems. Such activities include, but are not limited to (emphasis added), the installation and maintenance of groundwater monitoring wells and GPS stations (with associated equipment such as pumps, electrical connections, drainage pipes and access pathways) for the purpose of monitoring landslide movement, the filling of fissures, the re -contouring of slide debris, the creation and maintenance of emergency access roads, and geologic investigations involving trenching or boring performed mechanically or by hand (with allowance for access of any necessary mechanical equipment). Where practicable, areas of temporary CSS disturbance will be promptly re -vegetated with CSS habitat after completion of abatement activities (see Section 6.0 of the Plan for details about the restoration plan). It is estimated that such landslide abatement measures will result in the combined loss of a maximum of 5 acres of CSS habitat and 15 acres of non-native grassland. It is estimated that two-thirds of the impacts will occur within the Preserve. Point locations for two gnatcatchers and one island green dudleya occur in areas potentially subject to landslides. • 5.2.4 Miscellaneous Drainage Repair in Landslide Areas The repair of existing drainage systems becomes necessary by the City in landslide areas because of excessively heavy rainfall or damage by landslide movement. It is anticipated that there will be a need to repair such drains on an as -needed basis. It is estimated that such activity will result in the combined loss of a maximum of 10 acres of CSS habitat and 15 acres of non-native grassland. It is estimated that two-thirds of the impacts will occur within the Preserve. Point locations for two gnatcatchers, two aphanisma, one south coast saltscale, and one island green dudleya occur in areas potentially subject to landslides. • 5.2.14 Utility Maintenance and Repair The installation, maintenance and repair of utilities and related infrastructure facilities by the City, other public agencies and/or utility companies, such as sewers, water, cable, telephone, gas, power, and storm drains (emphasis added) will occur throughout the City on an as -needed basis. Installation of new commercial antenna towers is not allowed in the Preserve. The installation, maintenance, and repair of these activities are anticipated to permanently impact up to 10 acres of CSS and 20 acres of non-native grassland throughout the life of the permits. It is estimated that one-half of the impacts will occur within the Preserve. To summarize, the Covered Activities described above include, but are not limited to, the installation and maintenance of groundwater monitoring wells and GPS stations for the purpose of monitoring landslide movement, the filling of fissures, the re -contouring of slide debris, the creation and maintenance of emergency access roads, and geologic investigations involving trenching or boring performed mechanically or by hand. Where practicable, areas of temporary CSS disturbance will be promptly re -vegetated with CSS habitat after completion of abatement activities. The NCCP/HCP provides details for the provision of a maximum of 27.5 acres of CSS habitat and 52.5 acres of grassland for activities and projects such as dewatering well, landslide abatement measures, drainage repair, and utility maintenance and repair in landslide areas (combined Preserve and non -Preserve properties), as detailed in the table below.

Expecting the surface drain work area within the City (the covered area of the NCCP/HCP) that would divert water runoff to the ocean based on a I00 -year storm event" is approximately 65 -feet in width, the following loss to CSS and Grassland is expected to occur (unrestricted area is in other words disturbed area, such as roads, development, etc.): 10 Proposed Project Work Areas Total Habitat Loss (Acres) In Preserve (Acres) Work Description Coastal Coastal Sage Scrub Grassland Unrestricted Sage Scrub Grassland Unrestricted Upper Portuguese Channel 4.0 0 1.0 4.0 0 1.0 Ishibashi Channel 5.2 0 0 4.0 1.2 0 Paintbrush Channel 2.5 0.1 0.3 2.3 0.1 0.3 Lower Portuguese Channel 0.2 2.5 1.3 0.2 1.0 0.0 Central Channel 0.5 1.3 0.3 0.5 1.3 0.3 East Channel 0.2 2.0 0.5 0.2 0.4 0.2 Ocean Discharge 0 1.1 0 0 0 0 Surface Fracture Infilling 0.2 0.2 0 0.2 0.2 0 Wells Permanent Work Area 0.1 0.1 0.2 0.01 0.01 0.01 Wells Temporary Work Area 0.3 1.1 2.0 0.1 0.1 0.1 Well Access Roads 0.3 1.1 0.2 0.1 0.3 0.1 Horizontal Drains Permanent Work Area 0.02 0.04 0 0.01 0.02 0 Horizontal Drains Temporary Work Area 0.2 0.4 0 0.1 0.2 0 Sewer Mains In roadways) 0 0 0 0 0 0 Total 13.6 10.0 5.7 11.6 4.8 2.0 10 With project implementation within the Palos Verdes Nature Preserve, there will be approximately 5.8 acres of unused CSS loss and 27.5 acres of unused Grassland loss available for future projects. As an added measure to ensure the City is able to conduct projects in the future that may not have been captured in the Covered Activities described in Table 5.1 of the NCCP/HCP, the following miscellaneous covered activity is included in the current NCCP/HCP that provides the City with additional CSS and Grassland loss, including within the Preserve: • 5.2.17 Other Miscellaneous City Projects It is foreseeable that during the life of this NCCP/HCP, the City will undertake a City project similar in character and impacts to those listed in Table 5-1 that is not specifically listed here as a Covered Project/Activity. Such projects shall be considered Covered Projects provided the total loss of CSS habitat and non-native grassland for said Miscellaneous City Projects does not exceed 20 acres of CSS habitat and 60 acres of non-native grassland as identified in Table 5-1. It is estimated that one-half of the impacts will occur within the Preserve. Soon after the October 2, 2017, NCCP workshop, City Staff, the PVPLC Staff, the Wildlife Agencies, and DBS&A Staff met to discuss the NCCP/HCP in relation to the Draft FS, and that some preliminary draft editing occurred to Section 5 to reflect the work described in the Draft FS. However, based on the above, Staff is of the opinion that the work proposed in the Draft FS adheres to the parameters of the current NCCP/HCP, and that no edits to the document are needed. The Covered Activities described in the NCCP/HCP are intentionally written broadly to allow the City maximum flexibility in conducting projects throughout the City, including landslide abatement measures, originally envisioned by the City Council in 1996 when they signed on to develop a NCCP/HCP. ADDITIONAL INFORMATION: Next Steps If the Council adopts the Portuguese Bend Landslide Feasibility Study, the following steps will need to occur before breaking ground (not in any particular order): • Adoption of the NCCP/HCP and Permit issuance by the Wildlife Agencies • Pre -Pilot Test Investigations and Pilot Testing/Reporting • Preparation of Engineering Plans • Identifying and Securing Funding Sources • Hiring a Construction Contractor • Obtaining Permits from Army Corps of Engineers for work within a blue -line stream • City Council Adoption of an Environmental Document pursuant to the California Environmental Quality Act • Obtaining a Coastal Development Permit from the Coastal Commission 11 • On-going Public Workshops Public Notification On December 22, 2017, a listsery was issued to "Breaking News" subscribers and a message posted on the City's Facebook and Nextdoor pages announcing the availability of the Draft FS and tonight's meeting. Public Comments Since the release of the Draft FS on December 22, 2017, the City has received 1 public comment (Attachment E). ALTERNATIVES: In addition to the Staff recommendations, the following alternative actions are available for the City Council's consideration: 1. Identify any issues of concern with the Draft FS, and provide City Staff and DBS&A with direction in modifying the document. 2.

INTRODUCTIONS Ray Mathys PowerPoint presentation Questions on presentation: 1. How deep is slide plane? Varies 2. Is the reef anchored: No 3. Does the bentonite extend below surf zone? No answer • Robert Douglas's book discusses clay and movement can the experts talk about surf action; wave actions is cutting the toe which keeps repeating and thus the slide moves; also ground water lubricates the slide and the slide moves. • What would shoreline look like if reefs were installed? 1) Dewatering and remove water is the most important 2) keep water out then install reef to prevent soil from being removed. • Kelvin found a line to Army Corps report • How does loading the toe of the slide work? Not well so far- no calculations performed but F=ma is still true so when calculated the correct F (weight) placed at the toe of the slide. The ma would be achieved to accomplish equilibrium.

"Projects" are well-defined actions that occur once in a discrete location whereas "Activities" are actions/operations that occur repeatedly in one location or throughout the Plan Area. The City's dedication and management to the Preserve of 1,123 acres, including the 499.9 acres of City Mitigation Lands, the management of 258.7 acres of Previous Mitigation Lands, and 20.7 acres of PVPLC lands, is intended to provide the necessary mitigation for CSS and grassland for Covered City and Miscellaneous Private Projects and Activities (both outside and inside the Preserve). Any potential impacts to properties within the Plan Area that were previously acquired with nontraditional section 6 HCP Land Acquisition grant funding (61.5 acres in Malaga Canyon) and funding provided the State will be subject to review and approval by the Wildlife Agencies to confirm consistency with the section 6 grant program and requirements associated with other State funding. All Covered Activities will be reviewed by the City to ensure their consistency with the NCCP/HCP. As they are proposed, the projects will be forwarded to and may be reviewed by the Wildlife Agencies during the applicable CEQA process (or other process) for consistency with this NCCP/HCP. The Covered City Projects/Activities are proposed to occur inside and outside of the Preserve and are anticipated to impact a maximum of 318.7 acres of non-native grassland and 120.5 acres of CSS. Of these total impacts, it is estimated that 62.5 acres of the impacted CSS (52%) and 155.8 acres of the impacted non-native grassland (49%) will occur within the Preserve. Included in the CSS loss are losses associated with southern cactus scrub, saltbush scrub, and coastal bluff scrub which are expected to be minimal. No more than 5 acres of southern cactus scrub, 2 acres of coastal bluff scrub, and 2 acres of saltbush scrub could be lost within the Preserve associated with Covered City Projects/Activities. The City will mitigate these impacts by dedicating land to the City lands to the Preserve and providing restoration and management funding for the Preserve (see Section 8.0). Of the 737 acres of CSS and associated vegetation communities within the Preserve, a maximum of 62.5 acres (<9%) could be impacted by Covered City Projects/Activities, leaving a minimum of 674.5 acres (92%) of CSS in the Preserve to be perpetually conserved. Of the 470.9 acres of grassland within the Preserve, a maximum of 155.8 acres (33%) could be impacted by Covered City Projects/Activities, leaving a minimum of 315.1 acres. Through Plan implementation non-native grassland within the Preserve may be restored to native habitat. Impacts to specific vegetation communities within and outside of the Preserve are described in individual project descriptions (Section 5.2). The Covered Private Projects are proposed to occur outside of the Preserve and are anticipated to impact a maximum of 262.8 acres of grassland and 99.5 acres of CSS. These impacts as summarized below and will be mitigated by each project proponent. Impacts to specific vegetation communities are described in individual project descriptions (Section 5.3). The total loss of habitat associated with Covered Project and D-1 SECTION FIVE covered Activities, Associated Impacts, and conservation Activities are quantified above. The effects of the habitat loss to the Covered Species are described in the conservation analysis in Appendix B of the Plan. Within the Coastal Zone, permissible impacts and mitigation to Environmentally Sensitive Habitat Areas (ESHA), as defined in Appendix F, will not only be consistent with the NCCP/HCP, but will also be consistent with the City's most current LCP. Furthermore, any impacts to habitat or ESHA's located in the Coastal Zone will be mitigated within the Coastal Zone. The NCCP/HCP area will be subject to CWA Sections 401 and 404, and California Fish and Game Code Section 1600 et seq. permit requirements if they are included within areas proposed for development. 5.2 Covered City Projects and Activities The following proposed Covered City Projects are addressed by this NCCP/HCP (see summary on Table 5-1 and Figure 5-2) and will be encumbered by conservation easements which are to be recorded on City - owned properties within the Preserve pursuant to Section 4.2 of this Plan. All mitigation for Covered City Projects/Activities will occur within the Preserve. 5.2.1 Altamira Canyon Drainage Project The City has identified the need for a project within the portion of Altamira Canyon that traverses the Portuguese Bend landslide area to address drainage and erosion and to prevent water from percolating into the landslide plane. The removal of the Canyon's existing vegetation will result in the loss of 2.5 acres of CSS habitat and 3 acres of non-native grassland. Point locations for one gnatcatcher and one PVB hostplant occur in the project vicinity. Although this project is not being proposed at this time, it is likely that the project will be actively pursued during the life of the NCCP/HCP. 5.2.2 Dewatering Wells The installation of dewatering wells by the City in areas affected by the Portuguese Bend and Abalone Cove landslides has proven to be an effective method of slowing down landslide movement by removing groundwater from the slide plane. It is anticipated that new wells will be installed by the City in the future in or near areas of existing CSS habitat and grassland throughout landslide areas. It is estimated a maximum of 2.5 acres of CSS and 2.5 acres of non-native grassland will be impacted in the Preserve. A point location for one gnatcatcher occurs in the project vicinity. 5.2.3 Landslide Abatement Measures When and where required, landslide abatement activities within the Preserve and throughout the City are sometimes necessary by the City or other public agencies to safeguard existing roads, trails and drainage systems. Such activities include, but are not limited to, the installation and maintenance of groundwater monitoring wells and GPS stations (with associated equipment such as pumps, electrical connections, drainage pipes and access pathways) for the purpose of monitoring landslide movement, the filling of fissures, the re -contouring of slide debris, the creation and maintenance of emergency access roads, and D-2 SECTION FIVE covered Activities, Associated Impacts, and Conservation geologic investigations involving trenching or boring performed mechanically or by hand (with allowance for access of any necessary mechanical equipment). Where practicable, areas of temporary CSS disturbance will be promptly re -vegetated with CSS habitat after completion of abatement activities (see Section 6.0 of the Plan for details about the restoration plan). It is estimated that such landslide abatement measures will result in the combined loss of a maximum of 5 acres of CSS habitat and 15 acres of non-native grassland. It is estimated that two-thirds of the impacts will occur within the Preserve. Point locations for two gnatcatchers and one island green dudleya occur in areas potentially subject to landslides. Brush Management in Preserve for Fire Prevention Purposes 5-1. Brush Management in Preserve for Fire Prevention Purposes D-3 SECTION FIVE Covered Activities, Associated Impacts, and Conservation Locations of City Projects cJ-2 Covered by the NCCP/ICP 5-2. Locations of City Projects Covered by the NCCP/HCP 5.2.4 Miscellaneous Drainage Repair in Landslide Areas The repair of existing drainage systems becomes necessary by the City in landslide areas because of excessively heavy rainfall or damage by landslide movement. It is anticipated that there will be a need to repair such drains on an as -needed basis. It is estimated that such activity will result in the combined loss of a maximum of 10 acres of CSS habitat and 15 acres of non-native grassland. It is estimated that two- thirds of the impacts will occur within the Preserve. Point locations for two gnatcatchers, two aphanisma, one south coast saltscale, and one island green dudleya occur in areas potentially subject to landslides. 5.2.5 Palos Verdes Drive East Drainage Improvement Project Based on a comprehensive drainage study, the City has identified numerous drainage system deficiencies in the eastern portion of the City along Palos Verdes Drive East (PVDE). To address these drainage deficiencies, the City proposes to carry out several drainage improvement projects over an extended period of time. Although it is anticipated that most of the projects will occur within the existing improved street M11 SECTION FIVE covered Activities, Associated Impacts, and Conservation right-of-way, some projects may necessitate work in the adjoining canyon areas. It is estimated that such activity will result in the combined loss of a maximum of 5 acres of CSS habitat and 15 acres of non-native grassland outside the Preserve. Point locations for Covered species are not currently known from the proposed project area. 5.2.6 Miscellaneous Drainage Improvements The City anticipates that there will be the need to perform regular maintenance, repairs and upgrades on drainage systems in the City not located within the landslide areas or the Palos Verdes Drive East drainage project area. It is anticipated that the repair and improvement of these drainage systems will be necessary from time to time due to unexpected storm damage or due to the old age of the drainage systems. It is also anticipated that some of the projects may necessitate the creation and/or maintenance of retention basins, debris basins, and access roads. It is estimated that such activity could result in the combined loss of a maximum of 20 acres of CSS habitat and 60 acres of grassland in the Plan area. Of this total, it is estimated that 6.6 acres of CSS (33%) and 20 acres of grassland (33%) impacts will occur in the Preserve. Point locations for three gnatcatchers, two cactus wrens, two PV13 hostplants, one ES13 hostplant, one aphanisma, one island green dudleya and one woolly seablite occur in the vicinity of the proposed project(s). 5.2.7 Abalone Cove Beach Project The City has identified a need to improve public access and beach amenities at the existing Abalone Cove beach site. The project may involve the construction of a restroom/storage area, a gate house, parking lot, and shade structures, as well as improving the access road that leads from Palos Verdes Drive South to the beach and foot trails in the area. The grading associated with the proposed project may cause the loss of 1 acre of CSS habitat and 2 acres of non-native grassland within the Preserve. Any CSS re -vegetation shall be performed on site within the coastal zone of the Preserve. A point location for one island green dudleya occurs in the vicinity of the proposed project. Although this project is not being proposed at this time, it is possible that the project or a similar variation will be actively pursued during the life of this NCCP/HCP. 5.2.8 Rancho Palos Verdes Trails Plan Implementation The City's Trails Network Plan addresses existing and proposed trails outside and within the Preserve. The portion of the Trails Network Plan that addresses trails within the Preserve is a part of the Public Use Management Plan (PUMP), which is a Covered City Project described further in Sections 5.4.2 and 9.2.1 of this Plan. It is anticipated that implementation of the City's Trails Network Plan, which includes the Preserve Trails Plan component (see Sections 5.4.2 and 9.2.1.1), will result in the loss of some CSS and grassland habitat. Although the establishment of new trails through CSS habitat will be avoided where possible, it is anticipated that some trail maintenance, erosion repair, and re-routing for public safety reasons may occur within habitat areas. Although it is anticipated that trail widening could occur as a result of trail use over time, trails will be monitored for signs of widening, and managed to remedy the degradation (see Section 9.2.2.2 of the Plan). It is estimated that such activities will result in the combined loss of a maximum of 4 acres of CSS habitat and 10 acres of grassland. It is estimated that one-half of these impacts will occur within the Preserve (2 acres of CSS habitat and 5 acres of grassland). Point locations for two PVB D-5 SECTION FIVE covered Activities, Associated Impacts, and Conservation hostplants, one ESB hostplant, one island green dudleya, and one woolly seablite occur in the vicinity of the Preserve Trails Plan. 5.2.9 Lower San Ramon Canyon Repair It is anticipated that the City will undertake a major stormwater project in the Lower San Ramon Canyon to reverse the effects of erosion on the streambed in an attempt to reduce the active Tarapaca landslide from blocking water flow. Geologic studies have identified a landslide in the canyon that has the potential to create blockage of the stream flow. Blockage of the stream flow could cause water to percolate into the adjacent South Shores landslide. The project will reduce the likelihood of reactivating the South Shores landslide, which could result in the loss of the Switchbacks on Palos Verdes Drive East. It is estimated that the project will result in the loss of a maximum of 5 acres of CSS and 15 acres of grassland. It is estimated that one-half of the impacts will occur in the Preserve. One point location for one gnatcatcher occurs in the project vicinity. 5.2.10 Lower Point Vicente Pursuant to the City's approved Vision Plan, the City may develop a public recreational/educational project to augment the existing Point Vicente Interpretive Center located on a parcel of City -owned land referred to as Lower Point Vicente. The property is located between the Point Vicente Lighthouse property owned by the Coast Guard and the Oceanfront Estates residential development project. It is anticipated that development of the site may result in a maximum loss of 1.5 acres of CSS and 11.2 acres of non-native grassland outside of the Preserve. One point location for one ESB hostplant occurs in the vicinity of the proposed project. 5.2.11 Palos Verdes Drive South Road Repair The City anticipates that due to continual landslide movement in the Portuguese Bend landslide area, there will be a need to perform repair work on the portion of Palos Verdes Drive South that traverses the landslide, including but not limited to relocating the roadway if necessary. It is anticipated that such road repair activity may result in a maximum of 5 acres of CSS habitat loss and 15 acres of non-native grassland loss within the Preserve. One point location for one PVB hostplant occurs in the vicinity of the proposed project. 5.2.12 Upper Point Vicente As part of the City's approved Vision Plan, the City is considering development of a civic/cultural/community center at Upper Point Vicente Park. The project may result in a loss of 2 acres of CSS and 22 acres of non-native grassland. It is estimated that one-half of the impacts will occur within the Preserve. Point locations for one gnatcatcher and one cactus wren occur in the vicinity of the proposed project. me SECTION FIVE Covered Activities, Associated Impacts, and Conservation 5.2.13 Preserve Fuel Modification The City and PVPLC are required to perform annual fuel modification for fire prevention purposes within the Preserve by the Weed Abatement Division of the Los Angeles County Department of Agricultural Commissioner. The location and amount of fuel modification throughout the Preserve has been determined by the Los Angeles Weed Abatement Division in conjunction with the Los Angeles County Fire Department (see Figure 5-1) and is based on factors such as proximity of structures, steepness of slope, and fuel load. The methods for carrying out the required fuel modification are described in Section 9.2.2 of the Plan. The required City fuel modification is anticipated to result in a loss of 12 acres of CSS and 18 acres of non- native grassland in the Preserve. Changes to fuel modification that would result in greater impacts than depicted in Figure 5-1 and Table 5-1 would require additional review by the Wildlife Agencies and PVPLC, potentially including amending the Plan pursuant to Section 6.8 of the Plan. 5.2.14 Utility Maintenance and Repair The installation, maintenance and repair of utilities and related infrastructure facilities by the City, other public agencies and/or utility companies, such as sewers, water, cable, telephone, gas, power, and storm drains will occur throughout the City on an as -needed basis. Installation of new commercial antenna towers is not allowed in the Preserve. The installation, maintenance, and repair of these activities are anticipated to permanently impact up to 10 acres of CSS and 20 acres of non-native grassland throughout the life of the permits. It is estimated that one-half of the impacts will occur within the Preserve. 5.2.15 Unimproved City Park Projects In addition to its developed parks, the City has a number of unimproved park sites that may be improved in the future with recreational amenities. These unimproved parks sites include, but are not limited to, 17.5 - acre Grandview Park, 18.2 -acre Lower Hesse Park, 4.7 -acre Vanderlip Park, and 1 -acre Martingale Park. It is anticipated that development of these specific park facilities and any other unimproved City park facilities will result in loss of a maximum of 10 acres of CSS habitat and 20 acres of non-native grassland outside of the Preserve. 5.2.16 Malaga Canyon Drainage Improvements The City anticipates that there will be the need to perform regular maintenance, repairs, and upgrades on the drainage system within the City -owned Malaga Canyon open space. It is anticipated that the repair and improvement of these drainage systems will be necessary from time to time due to unexpected storm damage or due to the old age of the drainage systems. It is also anticipated that some of the projects may necessitate the creation and/or maintenance of retention basins, detention basins, debris basins, and access roads. It is estimated that such activity could result in the combined loss of a maximum of 5 acres of CSS habitat and 15 acres of non-native grassland within the Preserve. Any potential impacts will be offset to ensure that the biological values of the properties are maintained consistent with the section 6 grant funding used to acquire the property and will be subject to review and approval by the Wildlife Agencies. D-7 SECTION FIVE Covered Activities, Associated Impacts, and Conservation 5.2.17 Other Miscellaneous City Projects It is foreseeable that during the life of this NCCP/HCP the City will undertake a City project similar in character and impacts to those listed in Table 5-1 that is not specifically listed here as a Covered Project/Activity. Such projects shall be considered Covered Projects provided the total loss of CSS habitat and non-native grassland for said Miscellaneous City Projects does not exceed 20 acres of CSS habitat and 60 acres of non-native grassland as identified in Table 5-1. It is estimated that one-half of the impacts will occur within the Preserve. 5-1.

Included in the CSS loss are losses associated with southern cactus scrub, saltbush scrub, and coastal bluff scrub which are expected to be minimal. No more than 5 acres of southern cactus scrub, 2 acres of coastal bluff scrub, and 2 acres of saltbush scrub could be lost within the Preserve associated with Covered City Projects and Activities. 5.3 Covered Private Projects and Activities The following proposed Private Projects and Activities are covered (Covered Private Projects and Activities) by this NCCP/HCP (see Table 5-2 and Figure 5-4 below). 5.3.1 Lower Filiorum Development If any type of development project is approved on the 94.2 -acre Lower Filorum property, also known as the Point View property, the owner will be required as a condition of approval to dedicate to the Preserve Me SECTION FIVE covered Activities, Associated Impacts, and Conservation a minimum of 40 acres of the 94.22 -acre property, including a minimum 300 -foot -wide functional wildlife corridor on the southern edge of the property connecting to the Abalone Cove portion of the Preserve, as depicted in Figure 5-3, as mitigation for impacts to biological resources. Any required fuel modification for the proposed project will not encroach into the area dedicated to the Preserve, including the 300 -foot wildlife corridor. The City will work with the landowner to prepare a development agreement which will include a funding program for management and monitoring the lands to be dedicated to the Preserve. The intent of the 40 -acre dedication and 300 -foot -wide minimum wildlife corridor required for this project is to maintain a viable wildlife corridor through the Preserve after the proposed project is approved and constructed. Based on a biology report prepared by NRC in 2003, the Point View property is comprised of 70 acres of non-native grassland, 2.5 acres of CSS, 9.4 acres of disturbed CSS, 6.9 acres of exotic woodland, and 5.2 acres of disturbed vegetation. The minimum of 40 acres of dedicated Preserve shall include 1.5 acres to be provided as mitigation for previous brush clearing activities and 38.5 acres of mitigation for CSS and grassland losses resulting from any future development of the 94.22 -acre Lower Filiorum parcel. The inclusion of Lower Filiorum acreage in the Preserve will be a condition of approval for any development project subsequently approved for the Lower Filiorum property. If no approvals are obtained, there will be no obligation on the part of present or future property owner to dedicate these lands to the Preserve. Likewise, identifying these lands for potential inclusion in the Preserve in the text and maps of this NCCP/HCP does not constitute approval of development on the Lower Filiorum property. me SECTION FIVE Covered Activities, Associated Impacts, and Conservation Legend • Aphanisma o Ocean Locoweed .

Locations of Private Projects Covered by NCCP/HCP 5.3.2 Portuguese Bend Club Remedial Grading Because of its proximity to the active Klondike Canyon Landslide, the homeowners association of the gated residential community known as the Portuguese Bend Club may need to perform remedial grading on its property to prevent damage to its roads and to residents' homes. It is anticipated that the remedial grading activity will take place on property owned by the association, located on the western end of the community, or on the adjoining City -owned property. It is anticipated that the remedial grading activity will result in a loss of 3 acres of CSS habitat and 10 acres of grassland. One point location for the cactus wren occurs in the vicinity of this project. Mitigation for this Covered Private Project is addressed by the City conveying and managing 1,123 acres to the Preserve. For the Private Projects to be covered under the City's Plan, vegetation removal shall be offset by the project applicant paying a Mitigation Fee into the City's Habitat Restoration Fund using a 2:1 mitigation ratio for impacted CSS, a 0.5:Imitigation ratio for impacted non- native grassland, and a 3:1 mitigation ratio for impacted native grassland (as described in Section 2.2.1 of the Plan) occurring in areas greater than 0.3 acre. This Covered Private Project may mitigate by one of the following two methods: 1) Dedication of additional acreage to the Preserve that will add to the biological D-11 SECTION FIVE covered Activities, Associated Impacts, and Conservation function of the Preserve (the approval of the City, PVPLC, and the Wildlife Agencies is required for acreage to be dedicated to the Preserve) and the property owner must provide management funding for the additional acreage according to a Property Analysis Record or similar method; or 2) Payment of a Mitigation Fee to the City's Habitat Restoration Fund described in section 8.2.1.1 in an amount of $50,000 per acre for the total mitigation acreage required (e.g., 3 acres of CSS impact = $150,000.00). The Mitigation Fee must be paid to the City prior to the remedial grading taking place. The PVPLC and the City have determined that $50,000 (in 2015 dollars) is the cost to restore and maintain 1 acre of native habitat. The $50,000 Mitigation Fee will be reviewed periodically, no less than every three years, by the City and, if necessary, adjusted to account for inflation and/or higher than expected restoration and management costs. 5.3.3 Fuel Modification for Private Projects throughout the City For new private development projects on vacant land in the City, all fuel modification required by the Los Angeles County Fire Department and/or Los Angeles County Department of Agricultural Commissioner as a result of such new projects will occur outside of the Preserve unless the City and the Los Angeles County Fire Department and/or Agricultural Commissioner agree that no other options exist. For existing private development, the Los Angeles County Fire Department and Los Angeles County Department of Agricultural Commissioner have reviewed the existing private development that abuts the Preserve and have determined the amount of brush clearance needed within the Preserve to provide the code -required fuel modification zone for the protection of existing structures outside the Preserve (see Figure 5-1). In situations where fuel modification must occur in the Preserve, impacts are already addressed by the City dedicating 1,402.4 acres to the Preserve. For the Private Projects to be covered under the City's Plan, vegetation needed to be cleared for fuel modification shall be offset by the project applicant paying a Mitigation Fee into the City's Habitat Restoration Fund using a 2:1 mitigation ratio for impacted CSS, a 0.5:lmitigation ratio for impacted non-native grassland, and a 3:1 mitigation ratio for impacted native grassland (as described in Section 2.2.1 of the Plan) occurring in areas greater than 0.3 acre. Removal of cacti and other succulents within any required fuel clearing areas shall be avoided/minimized to preserve habitat for the coastal cactus wren and other Covered Species. The total Mitigation Fee payment required is calculated by multiplying the total acreage impacted by the required ratio for each habitat type. The Mitigation Fee payment shall be provided by the property owner benefiting from the fuel modification by one of the following two methods: 1) Dedication of additional acreage to the Preserve that will add to the biological function of the Preserve (the approval of the City, PVPLC, and the Wildlife Agencies is required for acreage to be dedicated to the Preserve) and the property owner must provide management funding for the additional acreage according to a Property Analysis Record or similar method; or 2) Payment of a Mitigation Fee to the City's Habitat Restoration Fund described in section 8.2.1.1 in an amount of $50,000 per acre for the total mitigation acreage required (e.g., 3 acres of CSS impact = $150,000.00). The Mitigation Fee must be paid to the City prior to the fuel modification taking place. The PVPLC and the City have determined that $50,000 (in 2013 dollars) is the cost to restore and maintain 1 acre of native habitat. The $50,000 Mitigation Fee will be reviewed annually by the City and if necessary adjusted to account for inflation and/or higher than expected restoration and management costs. D-12 SECTION FIVE covered Activities, Associated Impacts, and Conservation The anticipated loss from fuel modification resulting from Covered Private Projects/Activities within the Preserve is not expected to exceed 10 acres of CSS and 20 acres of grassland. Any loss of CSS beyond 10 acres and 20 acres of grassland is not a NCCP/HCP Covered Project/Activity. 5.3.4 Miscellaneous Private Projects Throughout the City Outside of the Preserve The City may issue a permit for any Private Project in the City which impacts CSS habitat and is not specifically identified in this NCCP/HCP as a Covered Activity provided that the project impacts are located outside of the Preserve and the impacts are mitigated by the project applicant as described in this section. Impacts to CSS shall be mitigated by the project applicant using a 1:1 mitigation ratio for impacted CSS. Because fire is a natural component of the CSS vegetation community, under normal circumstances natural re -growth of habitat is expected, and any land that once had CSS will be considered CSS for the purposes of this Covered Activity. The mitigation shall be provided by the project applicant by the payment of a Mitigation Fee to the City's Habitat Restoration Fund discussed in section 8.2.1.1 in the amount of $50,000 per acre based on the total mitigation acreage required. The Mitigation Fee must be paid to the City prior to issuance of the grading or building permit, whichever comes first. The PVPLC and the City have determined that $50,000 (in 2013 dollars) is the amount that is needed to restore and maintain 1 acre of native habitat. The $50,000 Mitigation Fee will be reviewed annually by the City and, if necessary, adjusted to account for inflation and/or higher-than-expected restoration and management costs. There are 23.6 acres of exotic woodland, 22.6 acres of disturbed vegetation and 262.8 acres of grassland located outside of the Preserve or Neutral Lands that will be impacted by potential development with no mitigation required by individual property owners under this NCCP/HCP because the loss of such lands would not affect any of the Covered Species. Furthermore, there are 99.5 acres of CSS habitat outside of both the Preserve and Neutral Lands which include the 27.7 acres of CSS that would be impacted by the other four specific private projects discussed in this Section 5.3 of the Plan. This would result in the potential for a total of 71.8 acres of CSS habitat outside the Preserve and Neutral Lands to be lost as a result of these miscellaneous private projects throughout the City. Since this CSS and grassland exist outside the Preserve and Neutral Lands and is not targeted for conservation, this Plan is assumes that all of this habitat could be lost over the life of this Plan as a result of miscellaneous private projects without affecting preserve design and/or species persistence. 5.3.5 Plumtree Development If a development project is approved on the 27 -acre Plumtree property and the owner opts to rely on this NCCP/HCP to mitigate any impacts to biological resources caused by the proposed development project, all impacts to biological resources addressed under this Plan on the 27 -acre Plumtree property will be considered adequately mitigated by the conveyance of 30 acres of functional and connected habitat on the Upper Filiorum property (190 total acres) in 2009, as described in Section 4.2.1 of the Plan, which has been dedicated to the Preserve with the appropriate conservation easement (see Appendix G to this Plan). Any required fuel modification for a proposed project on the Plumtree parcel will not encroach into the area D-13 SECTION FIVE covered Activities, Associated Impacts, and Conservation dedicated to the Preserve. Based on a biology report prepared by NRC on August 14, 2007, the 27 -acre Plumtree Parcel contains 19.7 acres of non-native grassland and 2.8 acres of disturbed CSS. In addition, one pair of gnatcatchers was observed. The donation of the 30 -acre parcel by the property owner and its subsequent dedication to the Preserve as mitigation for any future upland biological impacts does not constitute nor imply approval of any subsequent development project on the Plumtree property by the City or determination of consistency with the NCCP/HCP by the Wildlife Agencies. 5-2. Total Loss of Habitat by Privately Covered Proiects and Activities 5.4 Other Covered Activities The following Covered Activities are expected to occur in the Preserve due to short- and long-term operation and maintenance requirements or emergency situations conducted by the City, other public agencies, or utility companies seeking Third -Party Participant status. These activities are not expected to involve the permanent loss of habitat. All of these activities listed below may not occur without first notifying the City. Any activity not identified below as a Covered Activity may not be initiated in the Preserve without prior notification to the PVPLC and concurrence from the Wildlife Agencies. The following Covered Activities shall adhere to the Habitat Impact Avoidance and Minimization Measures for Covered Activities outlined in Section 5.5 of the Plan as part of all operations and authorizations to precede work, where applicable: 5.4.1 Operation and Maintenance • Landslide abatement and monitoring activities that do not result in the loss of Covered Species and/or habitat. The regular maintenance and repair of existing drainage facilities and existing access roads within the Preserve that does not result in the loss of Covered Species and/or habitat. • The maintenance of existing access roads in the Preserve provided there is no loss of Covered Species and/or habitat. • Geologic testing and monitoring for public health and safety reasons, provided there is no loss of Covered Species and/or habitat.

D-14 SECTION FIVE covered Activities, Associated Impacts, and Conservation • Installation, maintenance, and repair of utilities and related infrastructure(s) that are necessary to serve the Covered Private Projects identified in Section 5.2 of the Plan provided there is no loss of Covered Species and/or habitat. • Maintenance and repair of utilities and related infrastructure(s) provided there is no loss of Covered Species and/or habitat. • The maintenance and repair of existing water quality basins, retention basins, detention basins, and debris basins, provided there is no loss of Covered Species and/or habitat. • Photography and filming, provided a City permit is obtained, no grading is involved, no new access road or trails are created, and impacts to Covered Species and/or habitat are avoided. • City and Los Angeles County law enforcement activities, including vehicular access. 5.4.2 Public Use Public access to the Preserve is conditionally allowed for passive recreational purposes and to promote understanding and appreciation of natural resources. Excessive or uncontrolled access; however, can result in habitat degradation through trampling and erosion (e.g., along trails) and disruption of breeding and other critical wildlife functions at certain times of the year. In order to balance the public's passive recreational needs with the protection of natural resources within the Preserve, a Public Use Master Plan (PUMP) has been developed jointly by the City, the public, and PVPLC to address public access issues. The PUMP is a proposed City -Covered Project incorporated into the Plan; therefore, it must be approved by the Wildlife Agencies as part of the NCCP/HCP before the activities, including the Preserve Trails Plans, will be allowed. The following public uses and activities are considered conditionally Covered Activities in the Preserve if they conform to the PUMP: • Public use and implementation of the Preserve Trails Plan (PTP) contained in the Wildlife Agency -approved PUMP. Section 9.2.1.1 of this Plan provides the design criteria and guidelines that will be used for the PTP. • Closure of existing trails within the Preserve that are not included in the PTP, as approved by the City Council and Wildlife Agencies. • Passive recreational activities (e.g., horse riding, hiking, bicycling, wildlife viewing) as described in the PUMP and approved by the City and Wildlife Agencies. • Subject to the PUMP, the creation and maintenance of passive overlook or vista areas with seating benches and trail markers may be located at key vista points near existing trails in the Preserve, provided no existing habitat will be lost. The location of these overlooks shall be located to avoid or minimize direct and indirect impacts to biological resources. The location of these overlooks will be approved by City Council. • Installation and maintenance of benches, picnic tables, tie rails, portable toilets, and trash cans within the Preserve and near Preserve boundaries, provided no existing habitat will be lost. The location of these facilities shall be sited to avoid or minimize direct and indirect impacts to D-15 SECTION FIVE covered Activities, Associated Impacts, and Conservation habitat and Covered Species. Location of overlooks shall be reviewed for consistency with the PUMP and this Plan and approved by the City Council prior to initiation of any implementation work. • Installation of trailhead signage/kiosks within the Preserve adjacent to existing roads or other access ways and away from sensitive resource areas. The location of trailhead signage/kiosks shall be reviewed for consistency with the PUMP and this Plan and approved by the City prior to initiation of any implementation work. • Operation and maintenance of the existing archery range in its current location and acreage (approximately 8 acres) within the Preserve, provided the appropriate City permits are maintained and the facility is not expanded. • Operation of the existing agricultural use at Upper Point Vicente of approximately 5 acres in size provided the appropriate City approval is maintained and all agricultural practices and improvements remain consistent with this NCCP/HCP. No other agricultural activities are allowed in the Preserve. • Night use of the Preserve provided use is limited, controlled, monitored, and managed consistent with the Palos Verdes Nature Preserve Night Hike Regulations. The City will issue a permit for night use and any night use of the Preserve shall be consistent with the requirements of this Plan. A summary of night use in the Preserve will be included in the Annual Report. 5.4.3 Preserve Management Management of the Preserve in accordance with the provisions described in Sections 8.0 and 9.0 of the Plan is a Covered Activity. Specific management Covered Activities anticipated to occur in the Preserve include the following: • Monitoring of Covered Species • Vehicular access • Habitat restoration • Invasive species control • Predator control • Reintroduction of Covered Species • Photo documentation • Installation of signage • Trail maintenance • Maintenance of fire/fuel buffers • Field research and studies designed to contribute to the long-term protection of habitats and species and other basic research of habitats and species included in the Preserve. D-16 SECTION FIVE Covered Activities, Associated Impacts, and Conservation 5.5 Habitat Impact Avoidance and Minimization Measures for Covered Projects and Activities The City will ensure implementation of the following avoidance and minimization measures as enforceable conditions in all permits, operations, and authorizations to proceed with the Covered Projects and Activities listed in Sections 5.2 through 5.4 of this Plan: 1. The City will review proposed plans for Covered Project and Activities within and abutting the Preserve (e.g., access routes, staging areas) to ensure proposed Covered Activities are consistent with this NCCP/HCP. 2. The City and its Preserve Habitat Manager (i.e., PVPLC) will ensure that access to the Preserve to carry out Covered Activities is consistent with the approved Preserve Access Protocol (PAP) that is required to be created pursuant to Section 6.5.2 of this Plan. When accessing the Preserve, utility agencies and the City's Public Works Department must take measures to avoid and minimize, to the maximum extent possible, environmental damage, including damage to habitat and Covered Species. Existing access roads in the Preserve should be used wherever practical. Any unavoidable access routes outside existing roads or construction areas should be clearly marked. Any new roads, trails, and utility corridors will be located in areas that avoid/minimize impacts to Covered Species, habitat fragmentation and edge effects. The width of construction corridors and easements will be minimized. 3. The City and/or responsible private project applicants will be responsible for ensuring that an Erosion Control Plan is developed and implemented for any Covered Activities in the Preserve or abutting the Preserve that might result in erosion as determined by the City. Potential erosion control measures include siltation fencing, straw bales, sand bags, etc. 4. When stockpiling topsoil in the Preserve or on vacant lots abutting the Preserve, it will be placed only in areas that minimize the damage to habitat. If fill or topsoil is imported into the Preserve, the fill will be certified weed -free soil. 5. For any new development on vacant lots abutting the Preserve, construction staging areas will be located at least 15 meters (50 feet) away from the Preserve boundary and natural drainages. No - fueling zones will extend a minimum distance of 15 meters (50 feet) from all drainages and away from the Preserve boundary. 6. Construction footprints for Covered Projects and Activities in the Preserve or abutting the Preserve will be clearly defined with flagging and/or fencing and will be removed upon completion of the Covered Activities. 7. Cut/fill slopes outside of fuel modification zones within the Preserve will be re -vegetated with native species, or in the case of fuel modification zones, native plants recommended by Los Angeles County for fuel modification zones. Impacts to cacti and other succulents within any required fuel clearing areas shall be avoided/minimized to conserve habitat for the coastal cactus wren and other Covered Species. Sidecasting of materials during trails, road, and utility construction and maintenance within the Preserve will be avoided. D-17 SECTION FIVE covered Activities, Associated Impacts, and Conservation 8. Where feasible and appropriate, dust generated by the construction for Covered Activities within the Preserve or on vacant lots abutting the Preserve will be controlled via watering of earthmoving areas and non -paved roads and an off-highway speed limit restriction to 20 miles per hour (mph). 9. Any temporary safety or security night lighting for Covered Activities in the Preserve or on vacant lots abutting the Preserve will be selectively placed, shielded, and directed away from all native vegetative communities. 10. Prior to implementation of Covered Activities within the Preserve or on vacant lots abutting the Preserve (see Section 5.6) that may impact Covered Species or their habitat, the City will provide an education program to all personnel associated with project activities. The education program will describe 1) the potential presence of Covered Species and their habitats, 2) the requirements and boundaries of the project (e.g., areas delineated on maps and by flags or fencing), 3) the importance of complying with avoidance and minimization measures, 4) environmentally responsible construction practices, 5) identification of sensitive resource areas in the field, and 6) problem reporting and resolution methods. 11. Any biologist used for the implementation of this NCCP/HCP, including implementing these measures, will be subject to the Wildlife Agencies' review and approval. The City will submit the biologist's name, address, telephone number, resume, and three references (i.e., the names and contact information of people familiar with the relevant qualifications of the proposed biologist) at least 10 working days prior to initiating work. If the Wildlife Agencies do not respond within this 10 -day period, the City will assume that the biologists are approved. 12. For bird species that are not federally listed or Covered by the NCCP/HCP, if vegetation clearing must occur in the Preserve during the bird breeding season under the circumstances described in Sections 5.6.9 and 5.6. 10 below (defined here as February 15 -August 31), a pre -construction nest survey will be conducted and a 100 -feet avoidance/exclusion zone or a buffer/barrier zone to attenuate noise deemed appropriate by the Wildlife Agencies will be placed around all active nests (i.e., active nests with eggs or chicks) until the nestlings fledge or the nest fails. Further, no take of Fully Protected Species is allowed under this Plan (see Section 1.2.2 of the Plan). 13. Covered Plant Species and cacti may be removed from impact areas and relocated to an adjacent or suitable location within the Preserve, in coordination with the Wildlife Agencies. The City and its Habitat Manager shall be notified at least ten (10) working days prior to impacts for potential salvaging and relocation opportunities. 14. No new lighting shall be allowed in the Preserve except where essential for roadway, facility use, and safety and security purposes. New light sources abutting the Preserve will be oriented downward and away from habitat areas, and shielded, if necessary, so that the lighting does not impact wildlife and native vegetation. 15. Construction surveys for herpetofauna shall be conducted prior to and during the first days of initial grading in areas within the Preserve where significant populations are known to exist. The City, its Preserve Habitat Manager, and the Wildlife Agencies shall be notified of all findings and relocation efforts at least ten (10) working days after grading has occurred. Any relocation efforts shall also be reported in the City's Annual Report. 0 i SECTION FIVE covered Activities, Associated Impacts, and Conservation 16. Pre -construction surveys for raptor during the breeding season (January 31 -September 30), where evidence of suitable nesting habitat is present, shall be conducted by a qualified biologist no later than four days prior to any project vegetation removal or grading activities within or on vacant lots abutting the Preserve. If nesting raptors are present, a 500 -foot avoidance/exclusion zone or a buffer/barrier zone to prevent disturbance and attenuate noise will be placed around all active nests (i.e., active nests with eggs or chicks) and monitored until the nestlings fledge or the nest fails. If requested by the City or other entity, the qualified biologist may evaluate site conditions and determine that nest -specific buffers which vary from the avoidance/exclusion zone above are warranted based on topography, vegetation, type and duration of activity, and other factors. The Wildlife Agencies, in coordination with the City and qualified biologist, will be notified of the status of all raptor surveying and monitoring, including if less than 500 -foot avoidance/exclusion zone or buffer/barrier zone is proposed for the raptor species and what additional measures/monitoring are necessary. No take of Fully Protected Species is allowed under this Plan (see Section 1.2.2). 17. All project landscaping, erosion control and re -vegetation efforts within the Preserve shall use locally collected native vegetation/landscaping to the extent practicable and avoid those species listed on the California Invasive Plant Council's (Cal -IPC) Invasive Plant Inventory (see Section 5.6.4 and Appendix D of the Plan). All project landscaping, erosion control and re -vegetation efforts on vacant land abutting the Preserve are permitted to use non-native plants but shall be prohibited from using those species listed on the California Invasive Plant Council's (Cal -IPC) Invasive Plant Inventory (see Section 5.6.4 and Appendix D of the Plan). This requirement shall be incorporated as enforceable conditions in all City permits, operations, and authorizations to proceed with work. 18. Any proposed new or re -located trail within or abutting the Preserve shall comply with the requirements of the approved PUMP and this Plan. The design criteria and guidelines in Section 9.2.1.1 of this Plan shall be used by the City and its Preserve Habitat Manager in implementing the PUMP, including the Preserve Trail Plan component. These guidelines place an emphasis on avoiding or minimizing impacts to CSS habitat and Covered Species, including: 1) providing a 25 -foot setback to coastal bluffs; 2) using existing access roads wherever practical; 3) any new trails, shall be located in areas that minimize habitat fragmentation and edge effects (e.g., maximum of 4 foot -wide in core areas); 4) seasonally rotating or limiting use to minimize degradation; and 5) providing a 30 -foot upland buffer along major drainages. 19. For Covered Projects/Activities within the Preserve, the impact area (see Table 5-1, Total Loss of Habitat by Covered City Projects and Activities) shall be located on the least sensitive portions of the site as determined by existing site-specific biological and supporting information, and guided by the following (in order of increasing sensitivity): a) Areas devoid of vegetation, including developed areas, previously graded areas, disturbed and ruderal areas, and active agricultural fields; b) Areas of non-native vegetation, disturbed habitats, manufactured slopes, landscaped areas and eucalyptus/exotic woodlands (provided impacts to nesting birds are avoided); D-19 SECTION FIVE covered Activities, Associated Impacts, and Conservation c) Areas of grasslands (excluding native grassland); d) Areas containing coastal scrub and saltbush scrub communities and all wetlands, including riparian scrub; e) Areas containing southern cactus scrub, southern coastal bluff scrub, cliff face, rock shore and native grassland communities; f) Occupied habitat for Covered Species and hostplants for the Covered butterfly Species; current surveys will be conducted throughout potential Covered Species habitat prior to any Covered Projects or Activities to assess occupancy and determine avoidance and minimization measures; and, g) Areas necessary to maintain the viability of wildlife corridors. 5.6 Avoidance and Minimization Measures for Covered Species The City will ensure implementation of the following avoidance and minimization measures as enforceable conditions in all permits, operations, and authorizations to proceed with the Covered Projects and Activities listed in Sections 5.2 through 5.4 of this Plan. Species-specific conservation measures for covered species are described in detail in Appendix B and summarized here. These measures are required to maintain permit coverage for each species. 5.6.1 Aphanisma Surveys will continue to be conducted every 3 years within the existing fixed locations (PVPLC 2013), and the Preserve Manager will evaluate potential habitat restoration or enhancement opportunities as part of routine habitat management. Habitat restoration, including clearing of ice plant or other exotic plants adjacent to populations, unauthorized trail closures, and seeding for aphanisma will be included in the PHMP. Pre -project surveys will be conducted throughout potential aphanisma habitat prior to approving Covered Activities to assess occupancy and to determine avoidance and minimization measures. If an existing population will be impacted by Covered Projects/Activities, the project applicant will engage the Preserve Manager and work with the Wildlife Agencies to prepare and implement a habitat restoration plan, to be approved by the City and Wildlife Agencies that will ensure no net loss of aphanisma within the population. Habitat restoration will include use of seed collected from the project site or from previously collected seed. Impacts to newly discovered or established populations throughout the Plan Area will be offset with equivalent habitat restoration. No more than two populations will be impacted unless additional populations are located or successfully established in advance of the impact, and the City, PVPLC and Wildlife Agencies, through annual coordination meetings, document that the status of the species in the Preserve is stable and adequately conserved. Trails will be maintained, posted and patrolled to avoid/minimize encroachment into occupied habitat. 5.6.2 South Coast Saltscale Surveys will continue to be conducted every 3 years within the existing fixed locations (PVPLC 2013), and the Preserve Manager will evaluate potential habitat restoration or enhancement opportunities as part of D-20 SECTION FIVE covered Activities, Associated Impacts, and Conservation routine habitat management. Habitat restoration, including clearing of ice plant or other exotic plants adjacent to populations, unauthorized trail closures, and seeding for south coast saltscale will be included in the PHMP. Pre -project surveys will be conducted throughout potential south coast saltscale habitat prior to approving Covered Projects/Activities to assess occupancy and to determine avoidance and minimization measures. If an existing population will be impacted by Covered Projects/Activities, the project applicant will engage the Preserve Manager and work with the Wildlife Agencies to prepare and implement a habitat restoration plan, to be approved by the City and Wildlife Agencies that will ensure no net loss of south coast saltscale within the population. Habitat restoration will include use of seed collected from the project site or from previously collected seed. Impacts to newly discovered or established populations throughout the Plan Area will be offset with equivalent habitat restoration. No more than one population will be impacted unless additional populations are located or successfully established in advance of the impact, and the City, PVPLC and Wildlife Agencies, through annual coordination meetings, document that the status of the species in the Preserve is stable and adequately conserved. Trails will be maintained, posted and patrolled to avoid/minimize encroachment into occupied habitat. 5.6.3 Catalina Crossosoma Surveys will continue to be conducted every 3 years within the Preserve by the Preserve manager to monitor trends in population dynamics. Potential for habitat restoration actions that may benefit this species will be evaluated during routine habitat management. There are no Covered Projects/Activities with the potential to impact existing populations. If the large population in the Forrestal Reserve expands into an existing trail, routine trail maintenance as contemplated in the PUMP may require trimming or selective removal of some Catalina crossosoma individuals, only to the extent that it will maintain the existing width of an existing trail; impacts from the widening of an existing trail or a new trail would be subject to the conditions below. Pre -project surveys will be conducted in potential Catalina crossosoma habitat prior to any Covered Projects/Activities to assess occupancy and determine avoidance and minimization measures. If an existing population will be impacted by Covered Projects/Activities, the project applicant will engage the Preserve Manager and work with the Wildlife Agencies to prepare and implement a habitat restoration plan, to be approved by the City and the Wildlife Agencies that will ensure no net loss of Catalina crossosoma within the population. Habitat restoration will include transplantation or use of seedlings propagated from previously collected seed. Impacts to newly discovered or established populations throughout the Plan Area will be offset with equivalent habitat restoration. No more than one population will be impacted unless additional populations are located or successfully established in advance of the impact, and the City, PVPLC and Wildlife Agencies, through annual coordination meetings, document that the status of the species in the Preserve is stable and adequately conserved. Trails will be maintained, posted, and patrolled to prevent/minimize encroachment into occupied habitat. D-21 SECTION FIVE Covered Activities, Associated Impacts, and Conservation 5.6.4 Island Green Dudleya Surveys will continue to be conducted every 3 years within established locations to monitor trends in population dynamics, and potential habitat restoration actions that may benefit this species will be evaluated during routine habitat management. Pre -project surveys will be conducted within potential island green dudleya habitat prior to any Covered Project or Activity to assess occupancy, and to determine avoidance and minimization measures. If this species is detected during surveys, impacts to this plant are expected to be avoided. Where avoidance of island green dudleya is not feasible, the project applicant will engage the Preserve Manager and work with the Wildlife Agencies to prepare and implement a habitat restoration plan, to be approved by the City and Wildlife Agencies, that will ensure the impacts will be offset with equivalent habitat restoration. No more than 0.25 acre of occupied dudleya habitat will be impacted and no more than one impact per Reserve, unless additional populations are located or successfully established in advance of the impact, and the City, PVPLC and Wildlife Agencies, through annual coordination meetings, document that the status of the species in the Preserve is stable and adequately conserved. The PVPLC has a successful propagation program for this species at the PVPLC nursery, and this program will continue as part of the NCCP/HCP. This species can be successfully planted in suitable habitat. Trails will be maintained, posted, and patrolled to avoid/minimize encroachment into occupied habitat. 5.6.5 Santa Catalina Island Desert -Thorn Surveys will continue to be conducted every 3 years within established locations to monitor trends in population dynamics, and potential habitat restoration actions that may benefit this species will be evaluated during routine habitat management. Pre -project surveys will be conducted within potential Santa Catalina Island desert -thorn habitat prior to any Covered Project or Activity to assess occupancy, and to determine avoidance and minimization measures. If this species is detected during surveys, impacts to this plant are expected to be avoided. If an existing population will be impacted by Covered Projects/Activities, the project applicant will engage the Preserve Manager and work with the Wildlife Agencies to prepare and implement a habitat restoration plan, to be approved by the City and the Wildlife Agencies that will ensure no net loss of Santa Catalina Island desert -thorn within the population. Habitat restoration will include transplantation or use of seedlings propagated from previously collected seed. Impacts to newly discovered or established populations throughout the Plan Area will be offset with equivalent habitat restoration. No more than one population will be impacted, unless additional populations are located or successfully established in advance of the impact, and the City, PVPLC and Wildlife Agencies, through annual coordination meetings, document that the status of the species in the Preserve is stable and adequately conserved. The PVPLC has a successful propagation program for this species at the PVPLC nursery, and this program will continue as part of the NCCP/HCP. This species can be successfully planted in suitable habitat. Trails will be maintained, posted, and patrolled to avoid/minimize encroachment into occupied habitat. D-22 SECTION FIVE Covered Activities, Associated Impacts, and Conservation 5.6.6 Wooly Seablite Surveys will continue to be conducted at fixed locations every 3 years within the Preserve by the Preserve Manager to monitor trends in population dynamics, and potential habitat restoration actions that may benefit this species will be evaluated during routine habitat management activities. Pre -project surveys will be conducted within potential woolly seablite habitat for any Covered Project to assess occupancy and determine avoidance and minimization measures. For Covered Projects/Activities, this species will be avoided from areas to be impacted, if feasible. The project applicant will engage the Preserve Manager and work with the Wildlife Agencies to prepare and implement a habitat restoration plan, to be approved by the Wildlife Agencies, that will ensure the impacts will be offset with equivalent habitat restoration. No more than 0.25 acre of occupied woolly seablite habitat will be impacted, and no more than one impact per Reserve, unless additional populations are located or successfully established in advance of the impact, and/or the City, PVPLC and Wildlife Agencies, through annual coordination meetings, document that the status of the species in the Preserve is stable and adequately conserved. Trails will be maintained, posted and patrolled to avoid/minimize encroachment into occupied habitat. 5.6.7 EI Segundo Blue Butterfly Surveys will be conducted by the Preserve Manager every 3 years within the existing populations (Figure 2) to monitor trends in population dynamics. The Preserve Manager shall evaluate potential opportunities to expand this species' habitat. The host plant for this species will be included in the seed mix for restoration (active planting) within the Preserve in suitable areas, particularly in areas similar to the existing known ESB locations. Pre -project surveys will be conducted throughout the project area in potential ESB habitat, defined by presence of coast buckwheat, prior to any Covered Activity to assess occupancy and determine avoidance and minimization measures. Occupied ESB habitat will be defined by the extent of host plants in an area known to be occupied by ESB (i.e., any coast buckwheat within 50 feet of a shrub where ESB were observed), and impacts to occupied habitat will be avoided if possible. Where ESB is detected and impacts are unavoidable, the Wildlife Agencies will be provided the opportunity (with sufficient advanced notice) to relocate any and all larvae, pupae, or adults. Survey data will be used to assess the distribution of ESB within the host plant patch, and the City will work with the Wildlife Agencies to minimize impacts to ESB. No more than 5% of any existing ESB occurrence polygon will be impacted. Impacts to newly discovered or established occupied habitat patches will not exceed 10% of their distribution at the time of impact based on a habitat evaluation conducted within 1 year of the anticipated impact. For any impact to occupied habitat, host plants will be established onsite to offset the number of host plants lost during the project. Trails will be maintained, posted and patrolled to avoid/minimize encroachment into occupied habitat. 5.6.8 Palos Verdes Blue Butterfly The PVPLC shall regularly evaluate potential opportunities to expand this subspecies' habitat. The host plant for this species will be included in the seed mix for restoration (active planting) within the Preserve in suitable areas within coastal sage scrub and grassland habitat, particularly in historic areas. Pre -project D-23 SECTION FIVE covered Activities, Associated Impacts, and Conservation host plant surveys will be conducted in potential PVB habitat prior to any Covered Project/Activities to assess occupancy and determine avoidance and minimization measures. If host plants are identified, a 5 - foot buffer around host plants will be avoided if feasible. If avoidance of host plants is not feasible, focused PVB surveys will be conducted. If PVB is discovered during surveys, the Wildlife Agencies will be provided the opportunity (with sufficient advanced notice) to relocate any and all larvae, pupae, or adults. Occupied PVB host plants will be avoided when possible. Occupied habitat will be defined as host plants, including a 5 -foot buffer, within a 50 -foot buffer around any PVB observation. Trails will be maintained, posted and patrolled to avoid/minimize encroachment into occupied habitat. Because PVB host plants readily establish in disturbed areas, they may become established in trails and dirt roads throughout the Plan Area. Routine trail and road maintenance may impact host plants and potentially PVB individuals, and there will be no additional restrictions placed on trail or road maintenance based on presence of PVB. 5.6.9 Coastal California Gnatcatcher Surveys will be conducted every 3 years within the Preserve to monitor trends in population dynamics and to evaluate potential habitat restoration actions to benefit this species. The Preserve Manager shall regularly evaluate potential opportunities to expand and enhance gnatcatcher habitat, and the Plan will provide a net increase in gnatcatcher habitat within the Preserve. Implementation of species-specific management actions as part of the PHMP (e.g., invasive species removal) will also occur under the Plan. Pre -project surveys will be conducted in areas that contain potential gnatcatcher habitat. Construction for Covered Projects and Activities that may impact gnatcatchers will be scheduled to avoid the bird breeding season (February 15 -August 31). If, due to an urgent or emergency public health or safety concern determined by the City and Wildlife Agencies, these activities must occur from February 15 -August 31 within and/or adjacent to gnatcatcher habitat, gnatcatcher pre -project surveys will be conducted to determine nesting activity. Survey results will be submitted to the Wildlife Agencies for review. If nesting activity is detected, then all construction activity must occur outside of a 300 -foot buffer surrounding each nest. Reductions in the nest buffer may be possible depending on site-specific factors (e.g., topography, screening vegetation, ambient noise levels, etc.), in coordination with the Wildlife Agencies. Construction noise levels should not exceed 60 dBA Leq within the 300 -foot buffer zone unless authorized by the Wildlife Agencies. The buffer zones and noise limits will be implemented until the nestlings fledge or the nest fails. Status of the nest will be monitored by a qualified biologist. A report will be submitted to the Wildlife Agencies for review prior to discontinuing the noise limits and nest buffers. If grubbing or other construction related activities associated with Miscellaneous Drain Repair, Palos Verdes Drive South Road Repair, or Alta Vicente Reserve (Upper Point Vicente) must occur from February 15 -August 31 within and/or adjacent to gnatcatcher habitat, gnatcatcher pre -project surveys will be conducted to determine nesting activity. If nesting activity is detected, all construction activity must occur outside of a 50 -foot buffer surrounding each nest. Construction noise levels should not exceed 65 dBA Leq within the 50 -foot buffer zone. The buffer zones and noise limits will be implemented until the nestlings fledge or the nest fails. Status of the nest will be monitored by a qualified biologist. A report will be submitted to Wildlife Agencies for review prior to discontinuing the noise limits and nest buffers. Trails will be maintained, posted, and patrolled to avoid/minimize encroachment into suitable habitat. D-24 SECTION FIVE Covered Activities, Associated Impacts, and Conservation 5.6.10 Cactus Wren Surveys will be conducted every 3 years by the Preserve Manager within the Preserve to monitor trends in population dynamics and to evaluate potential habitat restoration actions that may benefit this species. The Preserve Manager shall evaluate potential opportunities to expand and enhance cactus wren habitat, and the expectation is that the Plan will increase cactus wren habitat within the Preserve. Implementation of species- specific management actions as part of the PHMP (e.g., invasive species removal, cactus planting) will also occur under the Plan, which will protect and enhance existing habitat. Pre -project surveys will be conducted in areas that contain potential habitat for the cactus wren. Construction or constructions related activities for Covered Projects and Activities that may impact cactus wrens will be scheduled to avoid the bird breeding season (February 15 -August 31) and to avoid or minimize direct impacts to mature cactus (i.e., greater than 1 foot in height), and preferentially avoid the most mature cactus in a particular stand). If, due to an urgent or emergency public health or safety concern determined by the City and Wildlife Agencies, these activities must occur from February 15 -August 31 and within 100 feet of any coastal sage scrub and cactus wren pre -prof ect surveys will be conducted to determine nesting activity. Pre -project surveys will consist of 3 survey days over a one-week period, including one survey within 3 days of construction. Survey results will be submitted to the City, PVPLC, and Wildlife Agencies. If nesting activity is detected, then all construction activity must occur outside of a 100 -foot avoidance buffer/barrier zone to attenuate noise surrounding each nest. No birds shall be disturbed or taken. Construction noise levels should not exceed 65 dBA Leq within the buffer zone. The buffer zones and noise limits will be implemented until the nestlings fledge. The status of the nest will be monitored, and a report with recommendations will be submitted to the Wildlife Agencies for review prior to discontinuing the noise limits and nest buffers. Other measures in the Plan to conserve populations of cactus wren include the following: • Trails will be posted and patrolled to avoid/minimize encroachment into occupied cactus wren habitat; • Locate new public access points and operational/maintenance activities to minimize/avoid areas occupied by cactus wren and where large stands of mature cactus (at least 1-3 feet tall) exist within the Preserve; and, • Impacts to cacti and other succulents within any required fuel clearing areas shall be minimized to maintain habitat for the coastal cactus wren and other species. Taller (1-3 feet) cactus that cannot be avoided should be salvaged where feasible and transplanted to suitable areas within the Preserve. D-25 SECTION FIVE Covered Activities, Associated Impacts, and Conservation 5.7 Restrictions and Requirements for Projects/Activities Abutting and Adjacent to the Preserve 5.7.1 Abutting Development Project Review In reviewing a proposed new development project that will impact potential Covered Species habitat abutting the Preserve, avoidance or minimization of impacts to biological resources and retention of native habitats will be addressed as part of plan design review. The site design review process will consider the locations of access and staging areas, fire and fuel modification zones, predator and exotic species control, fencing, signage, lighting, increased stormwater and urban runoff, increased erosion, increased noise levels, and public access to habitats supporting Covered Species in developing measures to avoid or minimize impacts to biological resources. Avoidance and minimization measures to reduce or eliminate impacts to biological resources will be incorporated as enforceable conditions in all City permits, operations, and authorizations to proceed with work. 5.7.2 Fencing and Lighting The following practices shall apply to new development projects on vacant lots abutting the Preserve: Fencing, Barriers, and Edge Treatment 1. Fencing, barriers, or functional edge treatment will be required for all new projects developed on existing vacant lots abutting the Preserve and shall be designed to prevent intrusion of domestic animals into the Preserve. This requirement may be waived with written approval from the Wildlife Agencies. 2. Prohibiting the use of gates, openings, or other entry means in project fencing, barriers and edge treatment that would allow direct human access to the Preserve, which would degrade the natural habitat. This requirement may be waived with written approval from the Wildlife Agencies. Lighting 1. All light sources abutting the Preserve shall be designed and constructed to be oriented downward and away from habitat areas and shielded, if necessary, to ensure there are no impacts to wildlife and native vegetation. 2. Lighting in new developments on vacant lots abutting the Preserve shall be avoided and/or minimized as appropriate through appropriate placement and shielding of light sources in compliance with the City's Municipal Code requirements for exterior lighting. 5.7.3 Equestrian Use Brown -headed cowbirds (Molothrus ater) are parasitic, nonnative species in California that contribute to the decline of many native bird species. This transient bird species originally followed bison herds and has adapted to follow domestic European livestock. As a result, any new corral or equestrian facility within the City that requires the approval of a Conditional Use Permit or Large Domestic Animal Permit by the City and D-26 SECTION FIVE covered Activities, Associated Impacts, and Conservation is located within 500 feet of the Preserve must have a qualified biologist monitor for cowbirds for three years, and every third year thereafter, to determine their presence. If cowbirds are present, a cowbird trapping program and/or other effective measures will be funded and implemented by the applicant. 5.7.4 Landscaping Landscaping can create conflicts with biological objectives of the Preserve by increasing the potential for introduction of non-native and invasive plant species in natural areas. These non-native species can displace native species in natural communities. Horticultural regimes can alter site conditions in the Preserve adjacent to landscaping by increased runoff, fertilization, pesticides, and other factors, all of which promote a shift from native to non-native flora. Additionally, the use of native cultivars not collected on site or in the proximity of the site can create genetic contamination through hybridization. Therefore, the following practices shall apply to all activities within the Preserve, including new development projects on vacant lots abutting the Preserve, and shall be incorporated as enforceable conditions in all City permits, operations, and authorizations to proceed with work. 1. Landscaping shall avoid those species listed on the California Invasive Plant Council's (Cal -IPC) Invasive Plant Inventory (see Section 5.6.4 and Appendix D of the Plan). 2. Irrigation shall be designed and maintained to avoid overspray or runoff into the Preserve. 5.7.5 Stormwater and Urban Runoff New development projects on vacant lots abutting the Preserve approved by the City will include mitigation measures or other conditions, as appropriate, to reduce the likelihood that a flood would adversely impact Covered Species and the conserved habitat. As a co -permittee of the RWQCB National Pollution Discharge Elimination System (NPDES) Permit, the City is required to adopt a Standard Urban Stormwater Mitigation Plan (SUSMP). The large majority of new development projects and significant redevelopment projects must meet SUSMP requirements to reduce pollution and runoff flows. The City's SUSMP includes a list of recommended source control and structural treatment Best Management Practices (BMPs). Additionally, City land use policies ensure that land use regulations and public improvements accommodate flood events that approximate the rate, magnitude, and duration of natural flood flows.

Trails CRITERIA Attachments: The PositionPaper 07-04-12.pdf Hello Dave, Elias, Irving, Ara and Debra, Welcome back. Here's to a very sensible and productive 2018. The ultimate objectives of "sustainable development" and being "safe" are unachievable. The compromises that are made along the way are very important. Attached is the whole Position Statement which The Western States Trail Foundation produced to introduce their TRAIL DEVELOPMENT / MAINTENANCE CRITERIA of July 4 2012. Page 2 is the stand-alone document which the RPV City Council approved on November 7, 2012. Page 1 describes why the criteria is needed in order to preserve/enhance trails in an environmentally sensitive environment. WSTF makes the point that a sustainable trails network needs to be engineered in conjunction with the water flow/capture engineering criteria provided in the Portuguese Bend landslide RFP. The Portuguese Bend Reserve Trails Plan is a hodge-podge of pre-existing utility access roads, farming access roads and "social" trails. The Public Use Master Plan (PUMP) Committee as managed by PVPLC was not permitted to make a trails network plan from "whole cloth". As a result, more than 50 percent of the trails which existed when the property was purchased have been eliminated. And, that is not represented in the CTP portion of the RPV Trails Network Plan. Now is the time to negotiate which trails should ultimately become reality to which CRITERIA. I will be happy to help. ...

Of particular importance is the order in which the "E"'s are introduced. Historically, the conversion of "social" trails into well maintained "public" trails has been poorly implemented. This need not be so. In the long run, it is less expensive to do it right at the onset of an opportunity. First is Engineering, The first step in any design is an agreement of the objectives. Start points (Point A) and destinations (Point B) must be established. The long term criteria for the trail corridor must be established to be uniform between each Point A and B. It is not feasible, nor appropriate, that every trail be ADA compliant. Second is Education. Like Driver Education, every new trail user needs to be taught trail use etiquette. It is a matter of safety. Simple things like those going down hill should yield to those coming up appear to have been forgotten. Third is Enforcement. Most of the time, "peer pressure" is effective and free. As with paved roadways, trail user conflicts will occur whenever someone behaves rudely, i.e. unsafety or not in the best interest of the community at large. Every legal regulation effort to control human behavior such as banning a certain type of use, will result in the expense of additional education (proliferation of signage), some sort of penalty on the offender and the expense of expediting the punishment. Given the rather universally agreed upon opinion that off-road circulation is a desired public amenity, every agency should start with funding the Engineering up front. It is even more cost effective when the engineering is designed in conjunction with some other "public work". Following is a suggestion of a trail development/maintenance criteria which if universally adopted by everybody from the Secretary of Agriculture (National Forest Service) and the Secretary of the Interior (National Parks Service) on down, would save us all a lot of grief and money in the effort to have public access to trails. When you can state exactly what you want, you have a chance of getting it. Share it, adopt it by resolution or policy, use it, make it your "matrix" for the future. TAIL E-3 WSTF July 4, 2012 Page 2 of 3 This is a concise model from which trail management authorities can choose and assign to a master plan application, a minimal, ultimate objective and avoid repeated environmental impact studies, reports etc. prior to when funding becomes available for actual Engineering, improvement or repair of a trail. TRAIT: DEVELOPMENT / MAINTENANCE CRITERIA* of July 4, 2012 "TYPE" is numbered from easiest to most challenging. TYPE GRADE PRISM** TREAD*** Average Maximum Distance+ Vertical Horizontal Minimum Width 1 3% 5% 30' 12' 8' S' 2 5% 10% 100' 15' 12' 8' 3 5% 15% 100' 15' 10' 8' 4 10% 15%++ 100' 1 12' 8'1 6' 5 10% 18%++ 100' 12' 6' 4' 6 10% 20%++ 100' 12' S' 3' 7 15% 20%++ 100' 12' 4' 2' These "guidelines" are based on the asgumption that all "unpaved pathways" are "multi -use trails" unless posted otherwise. The "TYPE" is assigned to promote the creation of pathways and the ongoing accommodation of various trail use needs from one destination to another.+++ For instance: TYPE 9 —Wheelchairs. (ADA compliant.) TYPE 2 — Large emergency vehicles. (Fire Department compliant.) TYPE 3 — Circulation by a large volume of various users and small emergency vehicles. (Reduce user conflicts.) TYPE 4 — Recreation by a large volume of various users. TYPE 5 — Recreation by a lesser volume of various users. TYPE 6 — Challenging or isolated recreation by a sparse volume. TYPE 7 — Habitat access recreation by a sparse volume. Note: Unimproved roadsides and all roadsides in residential Equestrian Zones should be maintained with at least a TYPE 6 "Prism". Any hardscape (such as a driveway) that crosses a trail tread should have an anti-skid surface. Vertical obstructions (such as. curbs and water bars) should be no more than six inches high. Access to ADA compliant alternate routes should be provided. * A criterion is a standard upon which a judgment or decision may be based. ** A trail "prism" is the area to be kept clear around the trail tread. Nothing higher than six (6) inches should obstruct the prism for more than two (2) linear feet along the trail. The trail tread need not be centered in the prism particularly for "line of sight", big old tree, and/or "safety triangle" considerations. *** The trail tread is to be unobstructed and essentially level from side to side with water drainage considerations. + There should be a level distance of at least eight (8) feet or a level turnout before and after any instance where the trail tread reaches the maximum grade for the maximum distance. ++ Grade can be steeper for short distances but from destination to destination, it must meet the average for the trail TYPE. (User expectation signage.) +++ A "destination" is a trailhead, vista point and/or a place where the trail TYPE can change without leaving someone stuck and having to backtrack, unintentionally. identify them with GPS waypoints. E-4 Environmental Considerations From the high mountain divide at Watson's Monument to Hodgson's Cabin is an area that the United States Congress has set aside as wilderness and has desig- nated it the Granite Chief Wilder- ness Area. This special area, established by the California Wilderness Act of Sep- tember 1984, is managed to offer soli- tude in a pristine and natural setting. Protection of this ecologically sensi- tive area is of prime importance to all who participate in the annual WSTF Tevis Cup Ride. Permission to cross the Granite Chief Wilderness Area is granted through a permit from the U.S. For- est Service. In return, they receive im- portant usage data upon which to base management decisions regard- ing use of the area. This cooperative arrangement between the Western States Trail Foundation and the U. S. Forest Ser- vice insures that the world-famous Tevis event will continue to qualify as an acceptable activity in the Granite Chief Wilderness Area for future years. Some general rules of conduct for riders and support crews should be kept in mind at all times when using the Granite Chief Wilderness Area. They 'include: Leave no trace of your visit. That is, do not leave behind any lit- ter or refuse whatsoever. It is every rider's responsibility to keep the trail as clean as it was found. Disturb nothing. Stay on the trail. Let other rid- ers pass at wide spots on the trail if at all possible. In this way, you will be minimizing your impact on the fragile ecosystem of the area. Be as quiet as possible. Noise also destroys the serenity of the area and should be kept to an absolute minimum. No smoking. Absolutely no fires are permitted in the Granite Chief Wilderness Area. Weare privileged to be the stew- ards of this magnificent trail and its heritage. sy following these simple guidelines, we can all do our part to preserve and hot th' special place on the Western States Trail for future generatic'
