Response to Comment 84-1. This comment provides an introduction to the comments contained in this letter. Please see Responses to Comments 84-2 through 84-6 below.
Response to Comment 84-2. This comment provides suggested text edits to Mitigation Measure BIO-MM2, which was contained in Section 4.C, Biological Resources, of the RDEIR. The City, in response to this comment, has revised Mitigation Measure BIO-MM2, as shown in Chapter 3, Corrections and Additions to the Draft EIR and RDEIR, of this Final EIR. The project applicant has agreed to the requirements of this revised mitigation with one exception as relates to the provision of fencing around each site. While the applicant would implement all other aspects of the suggested mitigation, including signage to discourage trespass, given the location of these habitat areas surrounded by existing vegetation and topography, the City has determined that such fencing is not necessary since the natural open space being maintained under the project design would provide an uninterrupted extension of native habitat to the preservation and mitigation areas required by the project, and further, the project would not provide any direct access to such areas. Nonetheless, all other provisions of revised Mitigation Measure BIO-MM2 would be implemented as stated in the comment.
Response to Comment 84-3. This comment provides suggested text edits to Mitigation Measure BIO-MM3, which was contained in Section 4.C, Biological Resources, of the RDEIR. The City, in response to this comment, has revised Mitigation Measure BIO-MM3, as shown in Chapter 3, Corrections and Additions to the Draft EIR and RDEIR, of this Final EIR in accordance with the text provided in the comment.
Response to Comment 84-4. This comment provides suggested text edits to Mitigation Measure BIO-MM4, which was contained in Section 4.C, Biological Resources, of the RDEIR. The City, in response to this comment, has revised Mitigation Measure BIO-MM4, as shown in Chapter 3, Corrections and Additions to the Draft EIR and RDEIR, of this Final EIR in accordance with the text provided in the comment.
Response to Comment 84-5. This comment recommends that the City complete the County’s MSHCP consistency review process prior to circulating the Final EIR for the proposed project. However, while the Department’s recommendation is acknowledged by the City, this is not a legal requirement and the applicant is willing to assume the risk associated with potential changes in project mitigation that may result from that process should the City publish the Final EIR (or certify the EIR and approve the project as proposed) prior to completion of the MSHCP consistency review and approval of the DBESP.

Attention: Jason Moquin, Senior Planner Re: GPA 13-003, CZ 13-002, Annexation 11 7, TIM 36544 The District does not normally recommend conditions for land divisions or other land use cases in incorporated cities. The District also does not plan check City land use cases or provide State Division of Real Estate letters or other flood hazard reports for such cases. District comments/recommendations for such cases are normally limited to items of specific interest to the District including District Master Drainage Plan facilities, other regional flood control and drainage facilities which could be considered a logical component or extension of a master plan system, and District Area Drainage Plan fees (development mitigation fees). In addition, information of a general nature is provided.
The District has not reviewed the proposed project in detail and the following comments do not in any way constitute or imply District approval or endorsement of the proposed project with respect to flood hazard, public health and safety or any other such issue:
• This project would not be impacted by District Master Drainage Plan facilities or any other proposed facilities of regional interest.
• An encroachment permit shall be obtained for any construction related activities occurring within District right of way or fac ilities: Mabey Canyon Debris Basin and Oak Street Channel. For further information, contact the District's Encroachment Permit Section at 951.955.1266.
GENERAL INFORMATION
This project may require a National Pollutant Discharge Elimination System (NPDES) permit from the State Water Resources Control Board. Clearance for grading, recordation or other final approval should not be given until the City has determined that the project has been granted a permit or is shown to be exempt.
If this project involves a Federal Emergency Management Agency (FEMA) mapped floodplain, then the City should require the applicant to provide all studies, calculations, plans and other information required to meet FEMA requirements, and should further require that the applicant obtain a Conditional Letter of Map Revision (CLO MR) prior to grading, recordation or other final approval of the project, and a Letter of Map Revision (LOMR) prior to occupancy.
If a natural watercourse or mapped floodplain is impacted by this project, the City should require the applicant to obtain a Section 1602 Agreement from the California Department of Fish and Wildlife and a Clean Water Act Section 404 Permit from the U.S. Army Corps of Engineers, or written correspondence from these agencies indicating the project is exempt from these requirements. A Clean Water Act Section 40 I Water Quality Certification may be required from the local California Regional Water Quality Control Board prior to issuance of the Corps 404 permit. c: Riverside County Planning Department

Re: Pechanga Tribe Comments on the Notice of Availability for the Recirculated Draft Environmental Impact Report on the Skyline Heights Project, GPA 13-003, C13-002, Annexation 117, TR 36544
Dear Mr. Moquin:
This comment letter is written on behalf of the Pechanga Band of Luisefio Indians (hereinafter, "the Tribe"), a federally recognized Indian tribe and sovereign government, regarding the Notice of Availability (NOA) for the Recirculated Draft Environmental Impact Report (RDEIR) on the above named Project. The Tribe formally requests, pursuant to Public Resources Code §21092.2, to be notified and involved in the entire CEQA environmental review process for the duration of the above referenced project (the "Project"), to be directly notified of all public hearings and scheduled approvals concerning this Project, and that these comments be incorporated into the record of approval.
Pechanga thanks the City of Corona for acknowledging the impacts to Tribal Cultural Resources (TCRs) and for providing mitigation to preserve and protect the sensitive Luisefio cultural resources and traditional landscapes found in this area, and for requiring both archaeological and Pechanga tribal monitoring during earthmoving activities. The State and Federal governments have mandated that impacts to cultural resources must be appropriately mitigated within the confines of development projects. However, the Tribe is concerned with the RDEIR as the proposed Cultural Resources mitigation measures in the MMRP are not inclusive of the measures that were confirmed via electronic mail by the City in January 2016. We further note that the standard City measures have been modified since January 2016, and thus, the Tribe recommends that the below measures be incorporated in the RDEIR and in all applicable environmental documents associated with the Project.

Pechanga Comment Letter to the City of Corona
Re: Pechanga Comments on the NOA for a RDEIR - Skyline Heights January 3, 2017
PECHANGA CULTURAL AFFILIATION TO PROJECT AREA
The Pechanga Tribe asserts that the Project area is part of Luisefio, and therefore the Tribe's, aboriginal, pre-contact territory, as evidenced by the existence of Luisefio place names, t6ota yixelval (rock art, pictographs, petroglyphs), travel/trail systems, natural resources and a Traditional Cultural Landscape (TCL) that includes varying degrees of overlapping significance.
The Pechanga Tribe has a specific legal and cultural interest in this Project as the Tribe is culturally affiliated with the geographic area that comprises the Project property and is the closest affiliated tribe to the Project location. The Tribe has specific knowledge of cultural resources and sacred places near the proposed Project which we have shared with the City on previous occasions for this and other projects.
The Tribe welcomes the opportunity to meet with the City to further explain and provide documentation concerning our specific cultural affiliation to lands within your jurisdiction, if so desired.
REQUESTED REVISIONS TO THE MITIGATION MEASURES
Pechanga is not opposed to this Project; however, we are opposed to any direct, indirect and cumulative impacts this Project may have to TCRs. The Tribe's primary concerns stem from the Project's proposed impacts on Native American cultural resources, which includes both the protection of unique and irreplaceable cultural resources, such as Luisefio village sites, sacred sites and archaeological items which would be displaced by ground disturbing work on the Project, and on the proper and lawful treatment of cultural items, Native American human remains and sacred items likely to be discovered in the course of the work.
The Tribe understands that the DEIR was recirculated to address specific biologic concerns identified during the original circulation. However, since that time, Pechanga has continued SB 18 consultation with the City and determined that the mitigation measures identified in the 2015 document are unclear and insufficient to properly address impacts to TCRs during earthmoving activities. In an electronic communication from January 2016, revised mitigation measures were directed to be included in the RDEIR. However, since they were not included in this document and as the City has since modified their standard measures, we suggest the below language to be included in the Final EIR and all applicable environmental documents associated with this Project.
The revised measures are included below (underlines are additions; strikeouts are deletions).
Mitigation Measure CR-1: In the event that archaeological materials ffi·e discovered during construction all effi·tl1 n1oving activity '<vithin and around the immediate discovery area shall be diverted until a. qualified archaeologist can assess the nature and significance Pechanga Cultural Resources • Temecula Band of Luiseiio Mission Indians Post Office Box 2183 •Temecula, CA 92592

Response to Comment 87-1. This comment provides an introduction to the comments contained in this letter and requests notification of future project-related activities. Please see Responses to Comments 87-2 through 87-11 below.
Response to Comment 87-2. This comment acknowledges the City’s cooperation with the Tribe regarding inclusion of mitigation measures in the EIR, but also suggests that specific changes to mitigation language were not included in the RDEIR as requested but that revised mitigation measures are provided for the City’s consideration. Although the City was provided the revised mitigation measures prior to preparation of the RDEIR, because the RDEIR was prepared only to address updated technical analysis related to biological resources, it was not appropriate to include revised Cultural Resources mitigation measures in that document. Rather, these changes were to be implemented in the Final EIR, as discussed further below. As such, in response to this request, the City has revised the mitigation measures contained in Section 4.D, Cultural Resources, of the Draft EIR in accordance with the suggested revisions, as shown in Chapter 3, Corrections and Additions to the Draft EIR and RDEIR, of this Final EIR.
Response to Comment 87-3. This comment provides background information regarding the Tribe’s cultural affiliation to the project area, which is acknowledged by the City. However, as this comment does not raise a substantive issue regarding the contents of the Draft EIR or RDEIR, no further response is warranted.
Response to Comment 87-4. This comment provides an introduction to the proposed revisions to mitigation measures related to Tribal Cultural Resources (TCRs), and again notes that these revisions were not incorporated into the RDEIR. However, as noted above, revisions to mitigation measures related to Cultural Resources was not appropriate in the RDEIR, as the only materials that were recirculated related to biological resources. As such, these changes were not implemented in the EIR at that time. Nonetheless, the City agrees with the suggested modifications and thus these text changes have been incorporated into Section 4.D, Cultural Resources, of the Draft EIR, as shown in Chapter 3, Corrections and Additions to the Draft EIR and RDEIR, of this Final EIR.

I would like to offer some public comment regarding the Skyline Heights project I have two concerns, Light Pollution, and reclaimed water.
I would like to have the community adopt and enforce ( along with SCE) a light pollution model zone. This is very importatnt as theis community has wildlife that will be negatively impacted by night time light pollution. You may refer to this link for more information. http://darksky.org/lighting/model-lighting-lawspolicy/recommended-lighting-zones/ Next I would request that the builder work with the DWP to bring the reclaimed ( marked with purple indicators) water to the neighborhood to reduce the impact of utilizing drinking water for landscaping. I would like them to imclude the communtiy of Orchard Glen at least up Trudy way in this endevor.
I am happy to have the homes built. I would like to see the city planning department adopt both of these measures night pollution and reclaimed water for all developments. Possibly the city could work with SCE to get a grant to modigy all the street lights to animal friendly/ star friendly lighting.
Please seriously consider these points.

Response to Letter 88
Response to Comment 88-1. This comment provides an introduction to the comments contained in this letter, which relate to light pollution and reclaimed water use. Please see Responses to Comments 88-2 through 88-4 below.
Response to Comment 88-2. The commenter suggests that the City has not adequately addressed light pollution associated with the project given the proximity to natural habitat areas. However, as discussed in Section 4.A, Aesthetics, of the Draft EIR, and in Section 4.C, Biological Resources, of the Draft EIR and RDEIR, light-related impacts (including indirect impacts to wildlife) would be less than significant with implementation of Project Design Features (PDFs). Such PDFs include shielding outdoor lighting such that no off-site light spillage occurs (in accordance with the CMC), discussed on page 4.A-14 of the Draft EIR, as well as PDF BIO-3, Lighting, on page 4.C-41 of the RDEIR, which states the following:
Outdoor lighting of residences will be designed so that all direct beams would be confined to dwelling sites. Project lighting will not intrude into the open space conservation areas. Street lighting, parking lot lighting, and other project-related illumination sources will be positioned, directed, and shielded so as to avoid “light spill” into the conserved areas. The proposed project will avoid any night lighting adjacent to the open space areas. Night lighting will not be used during the course of construction unless absolutely necessary. If necessary, the lights will be directed and shielded to minimize lighting of the surrounding habitat. The level of off-site lighting and lighting fixtures would comply with the applicable requirements and policies of the City of Corona.
With implementation of these PDFs, impacts related to light pollution and off-site light spillage, and related indirect effects, would be less than significant.
Response to Comment 88-3. Reclaimed water service for the project site is addressed in Section 4.N, Utilities and Service Systems, of the Draft EIR. As discussed on page 4.N-7 therein, a new 12-inch Zone 3 reclaimed water line is proposed as part of the City’s Foothill Parkway Westerly Extension Improvements and would be located in Foothill Parkway from Chase Drive to Serfas Club Drive and in Chase Drive from Foothill Parkway to Skyline Drive. This reclaimed water line is assumed to be in place prior to implementation of the proposed project. The project proposes a network of on-site reclaimed water pipelines to serve the project’s HOA and landscaped areas. These areas will be served by a potable water connection until the DWP provides reclaimed water pipelines to the project area. It is anticipated that the reclaimed water system improvements noted above that would serve the project site would be in place prior to initiation of construction activities. As such, and as suggested by the commenter, the project is planned to be served by reclaimed water service for non-potable applications. However, to the extent that the City expands reclaimed water service to areas suggested by the commenter (up Trudy Way to the Orchard Glen community), this is not germane to the EIR or the analysis presented therein. Therefore, no further City of Corona Skyline Heights Project

Skyline Heights Project - PLEASE DO NOT MOVE FORWARD
I am writing in hopes that this project will not move forward. As a resident of Corona, I deal with a daily commute to Irvine. I love that the Foothill Westerly Extension is open, I am able to get onto the 241 a little bit quicker, but more and more people are starting to use this road in the mornings. Traffic is loading up at Paseo Grande and Foothill as well as at the Green River on-ramp. Adding 292 single-family homes would elevate the traffic problem even more. It already takes 40-60 mins to get to the 241 toll-road from where I live (Main and Foothill). I would hate to see this number increase.
Thank you,

Response to Letter 89
Response to Comment 89-1. This comment expresses opposition to the proposed project and suggests that traffic-related impacts of the project will exacerbate traffic conditions in the area. While the commenter provides anecdotal information regarding traffic conditions, and the City acknowledges these concerns, this comment does not raise a substantive issue regarding the content of the Draft EIR or RDEIR or the analysis or conclusions therein. As such, no further response is necessary.

3. Corrections and Additions
to the Draft EIR and RDEIR
3. CORRECTIONS AND ADDITIONS TO THE DRAFT EIR AND RDEIR
3.1 INTRODUCTION
Any corrections to the Draft Environmental Impact Report (“Draft EIR”) and Recirculated Draft EIR (“RDEIR”) text and figures generated either from responses to comments or independently by the City, are stated in this section of the Final EIR. The Draft EIR and RDEIR text and figures have not been modified to reflect these EIR modifications.
These EIR errata are provided to clarify, refine, and provide supplemental information for the Skyline Heights Project. Changes may be corrections or clarifications to the text and figures of the original Draft EIR and RDEIR. Other changes to the EIR clarify the analysis in the EIR based upon the information and concerns raised by commentors during the public review period. None of the information contained in these EIR modifications constitutes significant new information or changes to the analysis or conclusions of the Draft EIR or RDEIR.
The information included in this EIR erratum that resulted from the public comment process does not constitute substantial new information that requires recirculation of the Draft EIR or RDEIR. The California Environmental Quality Act (“CEQA”) Guidelines, Section 15088.5, states in part:
(a) A lead agency is required to recirculate an EIR when significant new information is added to the EIR after public notice is given of the availability of the draft EIR for public review under Section 15087 but before certification. As used in this section, the term “information” can include changes in the project or environmental setting as well as additional data or other information. New information added to an EIR is not “significant” unless the EIR is changed in a way that deprives the public of a meaningful opportunity to comment upon a substantial adverse environmental effect of the project or a feasible way to mitigate or avoid such an effect (including a feasible project alternative) that the project’s proponents have declined to implement. “Significant new information” requiring recirculation includes, for example, a disclosure showing that:
(1) A new significant environmental impact would result from the project or from a new mitigation measure proposed to be implemented.
(2) A substantial increase in the severity of an environmental impact would result unless mitigation measures are adopted that reduce the impact to a level of insignificance. (3) A feasible project alternative or mitigation measure considerably different from others previously analyzed would clearly lessen the significant environmental impacts of the project, but the project’s proponents decline to adopt it.
(4) The draft EIR was so fundamentally and basically inadequate and conclusory in nature that meaningful public review and comment were precluded.

ESA PCR/SCH No. 2014021003 3-1
3. Corrections and Additions to the Draft EIR and RDEIR January 2017 (b) Recirculation is not required where the new information added to the EIR merely clarifies or amplifies or makes insignificant modifications in an adequate EIR.
The changes to the Draft EIR and RDEIR included in these EIR modifications do not constitute “significant” new information because:
• No new significant environmental impact would result from the project or from a new mitigation measure;
• There is no substantial increase in the severity of an environmental impact that would result unless mitigation measures are adopted that reduce the identified significant impacts to a level of insignificance;
• No feasible project alternative or mitigation measure considerably different from others previously analyzed has been proposed or identified that would clearly lessen the significant environmental impacts of the project; and
• The Draft EIR, inclusive of the RDEIR, is not fundamentally or basically inadequate or conclusory in nature such that meaningful public review and comment were precluded.
Therefore, recirculation of the Draft EIR or RDEIR is not required because the new information added to the EIR through these modifications clarifies or amplifies information already provided or makes insignificant modifications to the already adequate Draft EIR and RDEIR.
For simplicity, the EIR modifications contained in the following pages are in the same order as the information appears in the Draft EIR and RDEIR. Changes in text are signified by strikeouts (strikeouts) where text has been removed and by double underlining (underline) where text has been added. The applicable page numbers from the Draft EIR or RDEIR, respectively, are also provided where necessary for easy reference.

January 2017 3. Corrections and Additions to the Draft EIR and RDEIR Mitigation Measure CR-1: Tribal Monitoring. Prior to the issuance of a grading permit the applicant shall contact the consulting Native American Tribe(s) that have requested monitoring through consultation with the City during the SB 18 process ("Monitoring Tribes”). The applicant shall coordinate with the Tribe(s) to develop individual Tribal Monitoring Agreement(s). A copy of the signed agreement(s) shall be provided to the City of Corona Planning Department prior to the issuance of a grading permit. The Agreement shall address the treatment of any known tribal cultural resources (TCRs) including the project's approved mitigation measures and conditions of approval; the designation, responsibilities, and participation of professional Tribal Monitors during grading, excavation and ground disturbing activities; project grading and development scheduling: terms of compensation for the monitors; and treatment and final disposition of any cultural resources, sacred sites, and human remains/burial goods discovered on the site per the Tribe(s) customs and traditions and the City’s mitigation measures/conditions of approval. The Tribal Monitor will have the authority to stop and redirect grading in the immediate area of a find in order to evaluate the find and determine the appropriate next steps. in consultation with the Project archaeologist.
In the event that archaeological materials are discovered during construction, all earthmoving activity within and around the immediate discovery area shall be diverted until a qualified archaeologist can assess the nature and significance of the find, and, if necessary, develop appropriate treatment measures. Treatment measures typically include development of avoidance strategies, capping with fill material, or mitigation of impacts through data recovery programs such as excavation or detailed documentation.
If during cultural resources monitoring the qualified archaeologist determines that the sediments being excavated are previously disturbed or unlikely to contain significant cultural materials, the qualified archaeologist can specify that monitoring be reduced or eliminated.
Native American monitors from affected Tribes shall observe all project-related grading activities, and the treatment of any recovered artifacts shall be carried out in accordance with the provisions of a Treatment Agreement between affected Tribes. The Treatment Agreement shall be executed by the consulting Tribes prior to the issuance of grading permits for each construction phase. All cultural materials that are collected during the grading monitoring program and from any previous archaeological studies or excavations on the project site shall be curated according to the current professional repository standards. The collections and associated records shall be transferred, including title, to an appropriate curation facility which meets the standards set forth in 36 CFR Part 79 for federal repositories. All sacred sites, should they be encountered within the project area, shall be avoided and preserved as the preferred mitigation.
If changes are made to the project footprint to include earth-moving activities in areas not previously studied, additional archaeological investigations shall be required.
Mitigation Measure CR-2: Archaeological Monitoring. At least 30-days prior to application for a grading permit and before any grading, excavation and/or ground disturbing activities on the site take place, the Project Applicant shall retain a Secretary of Interior Standards qualified and RPA-certified archaeological monitor to monitor all ground-disturbing activities in an effort to identify any unknown archaeological resources/TCRs and assist with avoidance, preservation and/or mitigation per the City's Mitigation Measures on known resources.

1. The Project Archaeologist in consultation with the Monitoring Tribe(s), the Developer and the City, shall develop a Cultural Resources Monitoring Plan (CRMP) to address the details, timing and responsibility of all archaeological and cultural activities that will occur on the project site. Details in the Plan shall include:
a. Project grading and development scheduling;
b. The Project archeologist and the Monitoring Tribe(s) shall attend the pre-grading meeting with the construction manager and any contractors and will conduct a mandatory Cultural Resources Worker Sensitivity Training to those in attendance.
The Training will include a brief review of the cultural sensitivity of the Project and the surrounding area: what resources could potentially be identified during earthmoving activities; the requirements of the monitoring program: the protocols ·that apply in the event inadvertent discoveries of cultural resources are identified, including who to contact and appropriate avoidance measures until the find(s) can be properly evaluated; and any other appropriate protocols. All new construction personnel that begin work on the Project following the initial Training must take the Cultural Sensitivity Training prior to beginning work and the Project archaeologist and Monitoring Tribe(s) shall make themselves available to provide the training on an as-needed basis. c. The coordination of a monitoring schedule as agreed upon by the Monitoring Tribe(s), the Project archaeologist and the applicant;
d. The protocols and stipulations that the Developer. City, Monitoring Tribe(s) and Project archaeologist will follow in the event of inadvertent cultural resources discoveries. including any newly discovered cultural resource deposits that shall be subject to a cultural resources evaluation.
Mitigation Measure CR-3: Treatment and Disposition of Tribal Cultural Resources. In the event that Tribal Cultural Resources (TCRs) are inadvertently discovered during the course of grading for this Project and avoidance of the TCRs is not feasible, the following procedures will be carried out for treatment and disposition of the discoveries:
1. Temporary Curation and Storage: During the course of construction. All discovered resources shall be temporarily curated in a secure location onsite or at the offices of the project archaeologist. The removal of any artifacts from the project site will need to be thoroughly inventoried with tribal monitor oversight of the process: and
2. Treatment and Final Disposition: The landowner(s) shall relinquish ownership of all cultural resources, including all archaeological artifacts and non-human remains as part of the required mitigation for impacts to tribal cultural resources. Human remains, sacred/ceremonial items and burial good will be addressed per State Law.

Professional curation, including a curation agreement with a qualified repository in Riverside County that meets federal standards per 36 CFR Part 79, and which shall be made available to all qualified researchers upon application. The collections and associated records shall be transferred, including title, to an appropriate curation facility within Riverside County, to be accompanied by payment of the fees necessary for permanent curation;
b. At the completion of grading, excavation and ground disturbing activities on the site, a Phase IV Monitoring Report shall be submitted to the City documenting monitoring activities conducted by the project Archaeologist and Native Tribal Monitors within 60 days of completion of grading. This report shall document the impacts to the known resources on the property; describe how each mitigation measure was fulfilled; document the type of cultural resources recovered and the disposition of such resources; provide evidence of the required cultural sensitivity training for the construction staff held during the required pre-grade meeting; and, in a confidential appendix, include the daily/weekly monitoring notes from the archaeologist. All reports produced will be submitted to the City of Corona, Eastern Information Center and Monitoring Tribe(s).
Mitigation Measure CR-4: Sacred Sites. All sacred sites, should they be encountered within the project area, shall be avoided and preserved as the preferred mitigation, if feasible.
Mitigation Measure CR-5: Discovery of Human Remains. In the event that human remains (or remains that may be human) are discovered at the project site during grading or earthmoving. the construction contractors, project archaeologist, and/or designated Native American Monitor shall immediately stop all activities within 100 feet of the find.
The project applicant shall then inform the Riverside County Coroner and the City of Corona Community Development Department immediately, and the coroner shall be permitted to examine the remains as required by California Health and Safety Code Section 7050.5(b). Section 7050.5 requires that excavation be stopped in the vicinity of discovered human remains until the coroner has made the necessary findings as to origin If human remains are determined to be Native American,, the applicant shall comply with the state law relating to the disposition of Native American burials that fall within the jurisdiction of the NARC (PRC Section 5097). The coroner shall contact the NAHC within 24 hours and the NAHC will make the determination of most likely descendant(s). The MLD shall complete his or her inspection and make recommendations or preferences for treatment within 48 hours of being granted access to the site. Treatment and disposition of the remains shall be determined in consultation with the most likely descendant(s) to determine the most appropriate disposition of human remains and any associated grave artifacts. In the event that the applicant and the MLD are in disagreement regarding the disposition of the remains. State law will apply and the mediation process will occur with the NAHC. if requested (see PRC Section 5097.98(e) and 5097.94(k)).
The specific locations of Native American burials and reburials are confidential and may not be disclosed to the general public. The locations will be documented by the consulting archaeologist in conjunction with the various stakeholders and a report of findings will be filed with the Eastern Information Center (EIC). A Sacred Lands File form will be submitted to the NAHC by the project archaeologist and the Monitoring Tribe(s).

3. Corrections and Additions to the Draft EIR and RDEIR January 2017 According to the California Health and Safety Code, six or more human burials at one location constitutes a cemetery (Section 8100), and disturbance of Native American cemeteries is a felony (Section 7052).
Mitigation Measure CR-26: Prior to issuance of any grading permit, the Applicant shall retain a qualified vertebrate to develop a paleontological resource impact mitigation program (PRIMP) for excavations into the Upper Cretaceous Ladd Canyon Formation, the Upper Cretaceous Williams Formation, and Paleocene Silverado Formations. A qualified vertebrate paleontologist is defined as a paleontologist meeting the criteria established by the Society for Vertebrate Paleontology. The qualified vertebrate paleontologist shall conduct a pre-construction field assessment to locate fossils at surface exposures. The qualified vertebrate paleontologist shall supervise a paleontological monitor who shall be present at such times as required by the paleontologist during construction excavations into the fossiliferous formations mentioned above. Monitoring shall consist of visually inspecting fresh exposures of rock for larger fossil remains and, where appropriate, collecting wet or dry screened sediment samples of promising horizons for smaller fossil remains. The frequency of monitoring shall be determined by the paleontologist and shall be based on the rate of excavation and grading activities, the materials being excavated, and the depth of excavation, and if found, the abundance and type of fossils encountered. If resources are located, monitoring hours shall be increased as needed.
Mitigation Measure CR-37: If a potential fossil is found, the qualified vertebrate paleontologist or paleontological monitor shall be allowed to temporarily divert or redirect grading and excavation activities in the area of the exposed fossil, as determined appropriate by the monitor, to assess the significance of the find and, if necessary, develop appropriate treatment measures. Treatment measures may include avoidance or preservation in place, if feasible. If preservation or avoidance of the resource is not feasible, then the resource shall be removed from its location. Removal activities may consist of the relatively rapid removal of small isolated fossils from an active cut, to hand-quarrying of larger fossils over several hours, to excavations of large fossils or large numbers of smaller fossils from a bone bed over several days. These activities may include the assistance of the grading and excavation contractor’s equipment to facilitate removal.
Any fossils encountered and recovered shall be prepared to the point of identification and catalogued before they are donated to their final repository. Any fossils collected shall be donated to a public, non-profit institution with a research interest in the materials, such as the Natural History Museum of Los Angeles County, San Bernardino County Museum, the John D. Cooper Archaeological and Paleontological Curation Center at the California State University, Fullerton, or Western Science Center in Hemet, California.
Accompanying notes, maps, and photographs shall also be filed at the repository.
Mitigation Measure CR-48: Prior to the release of the grading bond, the paleontologist shall prepare a report summarizing the results of the monitoring and salvaging efforts, the methodology used in these efforts, as well as a description of the fossils collected and their significance. The report shall be submitted by the Applicant to the Community Development Director or his/her designee for approval. In addition, the report shall be submitted to at least one of the repositories mentioned in Mitigation Measure CR-37 and other appropriate or concerned agencies to signify the satisfactory completion of the project and required mitigation measures.

The location of the project site is shown in Figure 2-1, Regional and Vicinity Map. As shown in Figure 2- 1, the site is located in unincorporated Riverside County, approximately three miles south of State Route 71 (SR-71, Chino Valley Freeway) and SR-91 (Riverside Freeway) and approximately four miles west of Interstate 15 (I-15, Temecula Valley Freeway) along the southwestern boundary of the City of Corona.
The entirety of the project site and annexation area are located within the boundaries of the Cleveland National Forest, but is designated as Non-Forest System Land, which is not subject to the Cleveland National Forest land use regulations. However, the 270.9-acre project site and annexation area are is located adjacent to land designated as Forest Land within the CNF to the west and south. These “Forest Land” areas of the CNF National Forest is are accessed via Skyline Drive, a graded forest service access road to the south of the project site. This road provides recreational hiking and mountain biking opportunities to residents on a local and regional level. The project site and annexation area and also are southwest of the proposed Foothill Parkway Westerly Extension.

The Westerly Extension alignment passes through portions of the Municipal Water District (MWD) Lower Feeder Easement and Mabey Canyon Debris Basin. The adjusted alignment concept was developed with the goal of minimizing impacts to existing development and environmental resources and avoiding encroachments into the public “Forest Land” portions of the CNF adjacent to the project siteCleveland National Forest. The westerly extension would be a four-lane roadway from its existing terminus approximately 600 feet west of Skyline Drive to Green River Road. At Skyline Drive, the roadway would veer to the west into the unincorporated area of Riverside County and continue in an east/west direction along the City/County boundary. The alignment would then curve to the north and connect to Green River Road in the vicinity of Paseo Grande. The roadway construction would include either two parallel bridge structures or an aboveground arch structure to protect the existing 108-inch Metropolitan Water District (MWD) feeder line approximately 1,000 feet east of Paseo Grande.

4. Page 2-12. Modify text in the first two paragraphs from the top of the page as follows:
The project site is distinguished by two topographic regions divided by Mabey Canyon. The area north of Mabey Canyon consists of approximately 39 acres and the land outside the project boundary is bounded on the west is public “Forest Land” of the Cleveland National Forest. The property northeast of this area by is the proposed Foothill Parkway Westerly Extension and on the south by Mabey Canyon. The portion of the project site south of Mabey Canyon consists of approximately 232 acres and is situated near the mouths of Mabey, Tin Mine and Kroonen Canyons. At the south edge this area connects to the south terminus of Trudy Way near existing Tract 31955. An unimproved road leading from Mabey Canyon provides access to the southerly area. Vehicular access however, is limited, owing to the steep topography, which generally increases in elevation from the northeast to the southwest, and lack of maintenance of the road. Elevations over the site range from approximately 945 feet to 1,730 feet above mean sea level (AMSL).
The 270.9-acre project site is in an almost natural, undisturbed state. Steep topography with a thin soil mantle has precluded agricultural development common elsewhere in the general area. Very dense chaparral punctuated by sporadic stands of scrub oak covers most slopes. Unimproved roads from Mabey Canyon Road and Mangular Avenue provide access to this area. However, vehicular access is limited because of steep topography and other factors as noted above. Skyline Drive, which abuts the south edge of the annexation area, provides recreational access to the public “Forest Land” portions of the Cleveland National Forest.
Section 4.D – Cultural Resources
4. Page 4.D-15. Modify text in the last paragraph on the page as follows:
Despite the lack of known resources within the site, correspondence from representatives of the Pechanga and Soboba Bands of Luiseño Indians indicates the site has the potential to support previously undiscovered Native American resources. Of particular relevance, Ms. Hoover of the Pechanga Band of Luiseño Mission Indians, states that as the site includes dense vegetation, unidentified cultural resources may exist on the site. She states that the location of the site at the base of the Cleveland National Forest/Santa Ana Mountains likely contains a deep accumulation of alluvium which would have covered Luiseño habitations and villages over time. Additionally, she states that there are several drainages that flow from the mountains that would have supplied fresh water to any inhabitants in the area. Thus, the potential for impacting surface and subsurface cultural resources is high. In light of these considerations, it is concluded that unknown significant Native American cultural resources could be unearthed during project excavation activities. The project would involve surface disturbance and grading, and would require trenching for utilities. Grading and trenching as well as other construction ground-disturbing actions have the potential to disturb and destroy cultural resources. Disturbance of significant cultural resources would result in a significant adverse impact. Thus, Mitigation Measures CR-1 through CR-5 are is prescribed in the event that unknown cultural materials are discovered during construction. Mitigation Measures CR-1 through CR-5 also includes provisions for Native American monitors from affected Tribes to observe all project-related grading activities, and the implementation of a Treatment Agreement between affected Tribes. With the implementation of Mitigation Measures CR-1 through CR-5, potentially significant impacts to unknown resources would be reduced to a less than significant level.

Further, given that the City has fulfilled its obligations for Native American Consultation pursuant to SB18 and will continue to work with the Tribes to facilitate monitoring during future site development per Mitigation Measures CR-1 through CR-5 to ensure proper treatment of newly discovered resources, impacts to Native American resources would be less than significant with mitigation.
6. Page 4.D-16. Modify text in the paragraph under Impact 4.D-3 on the page as follows:
The paleontological resources assessments for the project found that the fossiliferous Upper Cretaceous Ladd Canyon Formation and Upper Cretaceous Williams Formation occur on the project site. In addition, the fossiliferous Paleocene Silverado Formation occurs within the project boundaries. These three formations have potential to contain significant, nonrenewable paleontological resources. Construction for the project would include grading and excavation for the development of housing pads, access roads, sewers, drains, culverts, and utility-related infrastructure that could impact paleontological resources in these three formations. Disturbance to paleontological resources could result in a potentially significant impact. Thus, Mitigation Measures CR-2 to CR-4 CR-6 through CR-8 have been prescribed to address this potentially significant impact. The mitigation measures require preparation of a paleontological resource impact mitigation program (PRIMP) to be implemented during construction activities for the project. The PRIMP would provide appropriate treatment measures for paleontological resources potentially impacted by the project. With implementation of these mitigation measures, potentially significant impacts to paleontological resources would be reduced to a less than significant level.
7. Page 4.D-19. Modify text in the consistency statement in right column of Table 4.D-1 for Policy 4.3.6 as follows:

8. Page 4.D-18. Modify text in the consistency statement in right column of Table 4.D-1 for Policy 4.3.7 as follows:
Consistent. Mitigation Measures CR-2 to CR-4 CR-6 through CR-8 address potential impacts to paleontological resources. Per the prescribed mitigation measures, a qualified vertebrate paleontologist would be retained by the City or project proponent to determine areas that would require paleontological monitoring during initial ground disturbance. Collected fossils, if any, would be transported to a paleontological laboratory for processing where they would be prepared to the point of curation, identified by qualified experts, listed in a database to facilitate analysis, and deposited in a designated paleontological curation. Following analysis, a report of findings with an appended itemized inventory of specimens would be prepared. The report and inventory, when submitted to the appropriate lead agency along with confirmation of the curation of recovered specimens into a public, non-profit institution with a research interest in the materials, would signify completion of the program to mitigate impacts on paleontological resources.

A qualified vertebrate paleontologist is defined as a paleontologist meeting the criteria established by the Society for Vertebrate Paleontology. The qualified vertebrate paleontologist shall conduct a pre-construction field assessment to locate fossils at surface exposures. The qualified vertebrate paleontologist shall supervise a paleontological monitor who shall be present at such times as required by the paleontologist during construction excavations into the fossiliferous formations mentioned above. Monitoring shall consist of visually inspecting fresh exposures of rock for larger fossil remains and, where appropriate, collecting wet or dry screened sediment samples of promising horizons for smaller fossil remains. The frequency of monitoring shall be determined by the paleontologist and shall be based on the rate of excavation and grading activities, the materials being excavated, and the depth of excavation, and if found, the abundance and type of fossils encountered. If resources are located, monitoring hours shall be increased as needed.
Mitigation Measure CR-37: If a potential fossil is found, the qualified vertebrate paleontologist or paleontological monitor shall be allowed to temporarily divert or redirect grading and excavation activities in the area of the exposed fossil, as determined appropriate by the monitor, to assess the significance of the find and, if necessary, develop appropriate treatment measures. Treatment measures may include avoidance or preservation in place, if feasible. If preservation or avoidance of the resource is not feasible, then the resource shall be removed from its location. Removal activities may consist of the relatively rapid removal of small isolated fossils from an active cut, to hand-quarrying of larger fossils over several hours, to excavations of large fossils or large numbers of smaller fossils from a bone bed over several days. These activities may include the assistance of the grading and excavation contractor’s equipment to facilitate removal.
Any fossils encountered and recovered shall be prepared to the point of identification and catalogued before they are donated to their final repository. Any fossils collected shall be donated to a public, non-profit institution with a research interest in the materials, such as the Natural History Museum of Los Angeles County, San Bernardino County Museum, the John D.

Cleveland National Forest Land Management Plan
The revised land and resource management plans (forest plans) for the southern California national forests, which includes the Cleveland National Forest Land Management Plan (CNF LMP), describe the strategic direction at the broad program-level for managing the land and its resources over the next 10 to 15 years.
The strategic direction was developed by an interdisciplinary planning team working with forest staff using extensive public involvement and the best science available.
The revised forest plans have a focus that is different from the old forest plans. The revised forest plans are outcome based and are focused on the condition of the land after project completion rather than the products removed from the land. Each forest plan is directed toward the realization of the desired conditions using strategies that are consistent with the concept of adaptive management and sustainable resource use. The revised forest plans are grounded on the concepts described by the Committee of Scientists in their report, Sustaining the People’s Lands. Paraphrasing the committee’s report, the term sustainability includes three components: ecological, social, and economic. Sustainability means meeting the needs of the present generation without compromising the ability of future generations to meet their needs.
The concept of sustainability is old; its broadened interpretation and redefinition should be viewed as a continuation of the attempt by Gifford Pinchot and others that followed him to articulate the meaning of 'conservation' and 'conservative use' of the lands and waters of the national forests. Therefore, the revised forest plans are designed so that managers have the flexibility to adapt management strategies to the constantly changing demands that are inherent to natural resource management. The strategic direction is expressed through an overall vision of what is wanted, the strategy for accomplishment, and the design criteria that will be used as activities are proposed, analyzed and implemented.
The forest plans were prepared according to the requirements of the National Forest Management Act (NFMA), the National Environmental Policy Act (NEPA), and other laws and regulations. The current forest plans for the southern California national forests were approved between 1986 and 1989. NFMA regulations City of Corona Skyline Heights Project
ESA PCR/SCH No. 2014021003 3-14
January 2017 3. Corrections and Additions to the Draft EIR and RDEIR require that each forest plan be revised every 10 to 15 years (36 CFR 219.10). The revised forest plans have been prepared to meet that requirement.
The CNF LMP presents a new format, which consists of three interrelated parts that work together to facilitate the use of adaptive management and the development of management activities that will collectively move the national forests toward their desired outcome. Part 1 paints the picture of the vision and conditions desired in the long-term. Parts 2 and 3 contain, respectively, the strategic management direction and the guidance for designing actions and activities in order to make progress toward the vision and desired conditions described in Part 1.

(a) Cleveland National Forest Land Management Plan
The following discussion evaluates the proposed project’s consistency with the applicable goals of the Cleveland National Forest Land Management Plan (CNF LMP). For each of the CNF LMP’s goals, the goal text is provided followed by a discussion of the project’s consistency with that goal.
Strategic Goals
Community Protection
Goal 1.1 - Improve the ability of southern California communities to limit loss of life and property and recover from the high intensity wildland fires that are a natural part of this state's ecosystem.
Project Consistency: Consistent. The proposed project is located adjacent to designated Forest Land and thus functions as part of the Urban-Wildland Interface. As such, and given the current wildfire hazard risk at the project site irrespective of the adjacent CNF Forest Land, the project design includes fuel modification surrounding the development as well as other features that minimize fire risk associated with the project. While the project is subject to elevated wildfire risks due to its hillside location and associated topography, vegetation, arid climate, and other factors, implementation of a Fuel Modification Plan approved by the Corona Fire Department would be required, as would compliance with applicable sections of the Corona Municipal Code for building construction, which would reduce potential wildfire hazards to acceptable levels. Therefore, while the project would introduce urban development into an area adjacent to CNF Forest Land, implementation of the proposed development would not measurably decrease the ability of the City of Corona or other communities in the area to limit loss of life and property and recover from the high intensity wildland fires.
Restoration of Forest Health
Goal: 1.2 - Restore forest health where alteration of natural fire regimes have put human and natural resource values at risk.
Project Consistency: Consistent. The proposed project is located within an area designated in the CNF LMP as “Non-Forest System Land”, and no physical development would occur as part of the proposed project on any areas designated as Forest Land in the LMP. While the project site, once developed, would comprise the edge of the City’s urbanized area and would be contiguous with urban development to the northeast, its development with urban uses would not have any direct effect on forest health.
Furthermore, the proposed project would not preclude forest restoration or otherwise detract from the ability of the USFS to restore forest health in areas of the CNF where alteration of natural fire regimes have put human and natural resource values at risk.
Invasive Species
Goal 2.1 - Reverse the trend of increasing loss of natural resource values due to invasive species.
City of Corona Skyline Heights Project
ESA PCR/SCH No. 2014021003 3-16
January 2017 3. Corrections and Additions to the Draft EIR and RDEIR Project Consistency: Consistent. The proposed project, as discussed in Section 4.C, Biological Resources, of the RDEIR, provides mitigation measures and project design features to minimize the proliferation of invasive species at the project site and in the surrounding area. Specifically, Mitigation Measure BIO-MM2 requires inspection and removal of invasive and non-native plants from preserved habitat areas on-site as well as performance criteria for success, including provision for control of nonnative and invasive species; Mitigation Measure BIO-MM15 requires that invasive plants identified in the County’s MSHCP should be removed from open space areas; and Project Design Feature BIO-5 requires that design guidelines be provided to homeowners in order to prohibit planting of invasive species.
Managed Recreation in a Natural Setting
Goal 3.1 - Provide for Public Use and Natural Resource Protection Project Consistency: Consistent. The proposed project is located outside of designated Forest Land areas, and would not hinder access to the CNF via the existing Skyline Trail adjacent to the property.
While no other dedicated public trails are located on the project site or annexation area, the applicant has committed to working with the community to develop a Trails Master Plan to improve trail access and facilities at the project site. While implementation of the proposed Trails Master Plan would not directly affect CNF Forest Land, it would facilitate public access to trails in the area, some of which provide access to designated CNF Forest Land areas and facilities. Furthermore, as discussed in the Draft EIR and RDEIR, the project would not result in significant impacts to natural resources, including biological resources, jurisdictional features, cultural resources, or agriculture or forestry resources.
Thus, the project would not limit access to public use areas within the CNF, which would be further enhanced with implementation of the proposed Trails Master Plan, and would also not result in significant impacts to natural resources with implementation of applicable mitigation measures.
Wilderness
Goal 3.2 - Retain a Natural Evolving Character within Wilderness.
Project Consistency: Consistent. The project site’s interface with adjacent CNF Forest Land would be delineated by signage, and where feasible, the project will provide a continuous connection with natural open space in areas directly adjacent to on-site habitat preservation. As noted above, the project would not result in significant impacts to biological resources with implementation of applicable mitigation measures, and would not have any direct effects on adjacent or nearby wilderness areas within the CNF. Thus, the project would not hinder USFS efforts to retain a natural evolving character within wilderness areas of the CNF.
Energy and Minerals Production
Goal 4.1a - Administer Minerals and Energy Resource Development while protecting ecosystem health.
City of Corona Skyline Heights Project
ESA PCR/SCH No. 2014021003 3-17
3. Corrections and Additions to the Draft EIR and RDEIR January 2017 Project Consistency: Not Applicable. The proposed project does not contain known mineral resources and is not located within a designated mineral resource area. Thus, the proposed project would have no effect on the ability of the USFS to administer minerals and energy resource development while protecting ecosystem health.
Goal 4.1b - Administer Renewable Energy Resource developments while protecting ecosystem health.
Project Consistency: Not Applicable. While it is possible that homes within the proposed development could utilize solar panels or other forms of renewable energy, the proposed project would have no effect on the ability of the USFS to administer renewable energy resource developments while protecting ecosystem health.
Watershed Function
Goal 5.1 - Improve watershed conditions through cooperative management.
Project Consistency: Consistent. The proposed project would provide mitigation for impacts to jurisdictional features on the project site, as discussed in Section 4.C, Biological Resources, of the RDEIR, and thus impacts to on-site watersheds would be less than significant. Mitigation for watershed impacts on-site would be subject to approval by various public agencies, including the Santa Ana RWQCB, U.S.
Army Corps of Engineers, and the California Department of Fish and Wildlife. While the project would result in direct effects to on-site drainages, for which mitigation is necessary, its implementation would not have any effect on upstream watersheds within CNF Forest Land areas.
Riparian Condition
Goal 5.2 - Improve riparian conditions.
Project Consistency: Consistent. The proposed project would provide mitigation for impacts to riparian/riverine resources on the project site, as discussed in Section 4.C, Biological Resources, of the RDEIR, and thus impacts to on-site riparian resources would be less than significant. Mitigation for riparian/riverine resource impacts on-site would be subject to approval by various public agencies, including the Santa Ana RWQCB, U.S. Army Corps of Engineers, and the California Department of Fish and Wildlife. While the project would result in direct effects to on-site riparian conditions, for which mitigation is necessary, its implementation would not have any effect on riparian conditions within CNF Forest Land areas further upstream.
Rangeland Condition
Goal 6.1 - Move toward improved rangeland conditions as indicated by key range sites.
Project Consistency: Not Applicable. The proposed project is not located in proximity to key range sites. As such, implementation of the proposed project would have no adverse effect on rangeland conditions in the CNF.
City of Corona Skyline Heights Project
ESA PCR/SCH No. 2014021003 3-18
January 2017 3. Corrections and Additions to the Draft EIR and RDEIR Biological Resource Condition
Goal 6.2 - Provide ecological conditions to sustain viable populations of native and desired nonnative species.
Project Consistency: Consistent. The proposed project would provide mitigation for impacts to special-status species and habitats on the project site, as discussed in Section 4.C, Biological Resources, of the RDEIR, and thus impacts to on-site populations of sensitive species would be less than significant.
Mitigation for species and habitat impacts on-site would be subject to approval by the California Department of Fish and Wildlife. While the project would result in direct and indirect effects to on-site species and habitats, its implementation would not have any significant effects on such resources within CNF Forest Land areas given implementation of required mitigation measures.
Natural Areas in an Urban Context
Goal 7.1 - Retain natural areas as a core for a regional network while focusing the built environment into the minimum land area needed to support growing public needs.
Project Consistency: Consistent. The proposed project once developed, would comprise the edge of the City’s urbanized area and would be contiguous with urban development to the northeast. While the project would develop currently undeveloped land with urban uses adjacent to CNF Forest Land areas, the project would also preserve a large portion of the property as natural open space, and implement a wide array of mitigation measures and project design features in order to minimize edge effects along the project’s interface with adjacent CNF Forest Land and nearby wilderness areas. Thus, the project would focus development on only a portion of the property and would implement a series of measures to limit adverse effects to the adjacent natural areas and provide habitat connections to the larger contiguous CNF wilderness.

Any current and future development projects within the City of Corona would be subject to environmental review on a project-by-project basis to evaluate consistency with applicable plans, policies, and regulations as well as the potential to divide a community or conflict with applicable conservation plans. As part of environmental review of individual projects, mitigation would be provided to address any physical impacts due to plan inconsistency. Therefore, the proposed project would not result in a cumulatively considerable contribution to land use impacts associated with dividing a community or plan inconsistencies and cumulative impacts would be less than significant.

4. Mitigation Monitoring and Reporting Program
4. MITIGATION MONITORING AND REPORTING PROGRAM
4.1 INTRODUCTION
This Mitigation Monitoring and Reporting Program (“MMRP”) has been prepared for use in implementing mitigation for the Skyline Heights Project. The program has been prepared in compliance with State law and the Environmental Impact Report (“EIR”) (State Clearinghouse No. 2014021003) prepared for the proposed project by the City of Corona.
The California Environmental Quality Act (“CEQA”) requires adoption of a reporting or monitoring program for those measures placed on a project to mitigate or avoid adverse effects on the environment (Public Resource Code Section 21081.6). The law states that the reporting or monitoring program shall be designed to ensure compliance during project implementation.
The monitoring program contains the following elements:
1) The mitigation measures are recorded with the action and procedure necessary to ensure compliance. In some instances, one action may be used to verify implementation of several mitigation measures.
2) A procedure for compliance and verification has been outlined for each action necessary. This procedure designates who will take action, what action will be taken, and when, and to whom and when compliance will be reported.
3) The program has been designed to be flexible. As monitoring progresses, changes to compliance procedures may be necessary based upon recommendations by those responsible for the program.
As changes are made, new monitoring compliance procedures and records will be developed and incorporated into the program.
This MMRP includes mitigation identified in the Initial Study and the Final EIR.
4.2 MITIGATION MONITORING AND RESPONSIBILITIES
As the Lead Agency, the City of Corona is responsible for ensuring full compliance with the mitigation measures adopted for the proposed project. The City will monitor and report on all mitigation activities.
Mitigation measures will be implemented at different stages of development throughout the project area. In this regard, the responsibilities for implementation have been assigned to the Applicant, Contractor, or a combination thereof. If during the course of project implementation it is discovered that the Applicant, Contractor, or other responsible party has failed to implement any of the required mitigation measures, the City shall be immediately informed, and the City will then inform any affected responsible agencies. The City, in conjunction with any affected responsible agencies, will then determine if modification to the proposed project is required and/or whether alternative mitigation is appropriate.

should be avoided during the critical nesting period of January 1 – September 1. If work cannot be avoided
during this timeframe, a nesting bird survey shall be
conducted by a qualified biologist within three (3) days prior to initiation of clearing and/or grading. If nesting birds are present, a nesting bird plan will be developed and implemented and include appropriate measures to
mitigate potential impacts, including maintaining a buffer area until fledging has occurred. Active bird nests should be mapped utilizing a hand-held global positioning
system (GPS) (getting as close as possible without
disturbing the nest) and a buffer will be flagged around the nest (typically 300 feet for most species, 500-foot buffer for raptor nests), as determined appropriate by the biologist. Construction should not be permitted within
the buffer area while the nest continues to be active
(eggs, chicks, etc.). Once fledging has occurred no further avoidance is required.

Project lighting will not intrude into the open space conservation areas. Street lighting, parking lot lighting, and other project-related illumination sources will be positioned, directed, and shielded so as to avoid “light spill” into the conserved areas. The proposed
project will avoid any night lighting adjacent to the open space areas. Night lighting will not be used during the course of construction unless absolutely necessary. If
necessary, the lights will be directed and shielded to
minimize lighting of the surrounding habitat. The level of off-site lighting and lighting fixtures would comply with the applicable requirements and policies of the City of Corona.

PDF BIO-4, Noise – The proposed project incorporates
landscape elements including trees, shrubs, and

promising horizons for smaller fossil remains. The
frequency of monitoring shall be determined by the
paleontologist and shall be based on the rate of
excavation and grading activities, the materials being
excavated, and the depth of excavation, and if found, the abundance and type of fossils encountered. If resources are located, monitoring hours shall be increased as
needed.
Mitigation Measure CR-7: If a potential fossil is found, the qualified vertebrate paleontologist or paleontological monitor shall be allowed to temporarily divert or redirect grading and excavation activities in the area of the
exposed fossil, as determined appropriate by the monitor, to assess the significance of the find and, if necessary, develop appropriate treatment measures. Treatment
measures may include avoidance or preservation in place, if feasible. If preservation or avoidance of the resource is not feasible, then the resource shall be removed from its location. Removal activities may consist of the relatively rapid removal of small isolated fossils from an active cut, to hand-quarrying of larger fossils over several hours, to excavations of large fossils or large numbers of smaller fossils from a bone bed over several days. These
activities may include the assistance of the grading and excavation contractor’s equipment to facilitate removal.
Any fossils encountered and recovered shall be prepared to the point of identification and catalogued before they are donated to their final repository. Any fossils collected shall be donated to a public, non-profit institution with a research interest in the materials, such as the Natural History Museum of Los Angeles County, San Bernardino

observed, mapped and approved by the Engineering
Geologist prior to fill placement. It is recommended that the bottoms of removals be surveyed and documented by
the Project Civil Engineer.
Groundwater, if encountered during grading, shall be
evaluated by the Geotechnical Engineer and/or
Engineering Geologist. In general, groundwater is not
anticipated to adversely affect grading although saturated soils and free water may be encountered along canyons
and within alluvium removals. If groundwater is
excessive, remedial measures such as horizontal drains or under drains may need to be installed. Further,
settlement monuments and plates (see Plate VI of the
Geotechnical Report) shall be installed during and after completion of grading to monitor settlement monuments
and plates shall be used to determine when the majority of the primary settlement has been completed to allow
for the release of affected lots for construction.
• Stripping: Vegetation, debris and other deleterious
materials are unsuitable as structural fill material and shall be disposed of offsite prior to commencing
removals and placement of compacted fills. The thick,
natural vegetative growth onsite is significant and will require consideration for removal. An onsite
mulching operation may be considered. The mulched
materials could then be used in future landscape
areas.
• Soil and Weathered Bedrock (unmapped): Loose,
compressible onsite soils and underlying weathered
bedrock shall be removed to expose the underlying
competent bedrock materials prior to placement of
compacted fill and when exposed in shallow cut area.
An average removal depth of 5 feet is anticipated for
removal of topsoil and weathered bedrock. In general,
onsite soils and weathered bedrock are suitable to be
re-used as structural fill when properly moistureCity of Corona Skyline Heights Project PCR Services Corporation/SCH No. 2014021003 4-29

conditioned.
• Undocumented Artificial Fill (locally mapped as
AFu): Fills associated with "recreational" grading,
construction of unpaved access roads, mining
operations and existing trench backfill shall be
removed prior to fill placement. Generally, these
artificial fills range from a depth of 3 to 20 feet. Local areas of undocumented fill associated with previous
geotechnical investigations are not plotted on the map.
Other fills, including roadway fills and trench backfill, are not mapped due to their localized extent and
minor thickness. Removals shall extend below the
undocumented fill until competent materials are
encountered.
• Alluvium/Colluvium (map symbol Qal): All alluvium
deposits exposed at existing or cut grades shall be
entirely removed prior to fill placement. These
deposits range in thickness from approximately 5 feet
to 35 feet. Ginter and Associates recommends that all
alluvial and colluvial soils below proposed fill areas
and in cut areas be removed to expose competent
bedrock or terrace deposits. Anticipated average
removal depths for alluvium/colluvium areas are
expected to vary to an estimated maximum thickness
of 35 feet.
Groundwater was not encountered during PSE's
subsurface investigation within the alluvium onsite.
However, access was limited and certain alluvial areas
could not be investigated such as within Krooner
Canyon. If "saturated" alluvium is encountered that
possesses a degree of saturation of 85% of more and is
consistent with depth to bedrock, consideration may
be given to leaving the saturated alluvium in-place,
provided that settlement time-delay consequences are
acceptable to the owner. If saturated alluvium is
encountered and is going to remain in-place, an

additional liquefaction investigation may be required
and dynamic settlement recommendations for those
areas will likely change.
• Older Alluvium (Qoa): All older alluvium shall be
removed to expose the underlying competent bedrock.
Generally, these deposits range in depth from 10 to
about 20 feet.
• Landslide Debris (Qls): All landslide debris that
could adversely affect the proposed development shall
be removed to expose the underlying competent
bedrock. Generally, these deposits range in depth
from 10 to about 29 feet, but may range up to around
35 feet in depth.
• Removals Along Grading Limits: Removals of
unsuitable soils shall be required prior to fill
placement along the grading limit. A 1:1 projection,
from toe of slope or grading limit, outward to
competent materials shall be established, when
possible. Where removals are not possible due to
grading limits, property line or easement restrictions, removals shall be initiated at the grading boundary
(property line easement, grading limit or outside the
improvement) at a 1:1 ratio inward to competent
materials. Where this reduced removal criterion is
implemented, special maintenance zones may be
necessary. Affected areas shall be established,
minimally, as a 1:1 projection from suitable removal
bottom to finish ground surface. This condition is
mainly expected in the slope areas. Where the
projection intersects the face of the slope, the
potential for distortion of the slope in response to
post-grading settlements exists and provisions for
future maintenance of such slopes shall be provided.

Mitigation Measure GEO-2: Slope Stability and
Remediation
• Cut Slopes: The majority of cut slopes have been
designed at a slope ratio of 2:1. The Engineering
Geologist shall observe cut slopes and cut slope
stabilization backcuts during grading. Modifications
to the recommendations presented herein will likely
be required based upon conditions exposed by
grading.
• Williams Formation (KW): Cut slopes within the
Williams Formation may expose adverse bedding that
shall require remediation. The cut slope superjacent
to Lots 278 and 279 is anticipated to require
replacement with a buttress fill. Probable buttresses
are anticipated for the cut slope above Lots 261
through 267 and the cut slope below the WQMP Basin
and Lots 247 through 255, as depicted on Figure 1 and
Figure 2 (pocket) of the Geotechnical Report.
• Ladd Formation: Cut slopes within the Ladd
Formation may expose adverse bedding that shall
require remediation. The majority of the cut slopes
should expose bedding dipping into the slope or at an
angle steeper than the proposed cut slopes (greater
than 60 degrees). Cut slopes within the Ladd
Formation that expose bedding dipping into the slope
or at an angle steeper than the proposed cut slopes are expected to be grossly stable; however, the final
determination shall be made based on exposed
conditions during grading. Cut slopes within the Ladd
Formation may expose conglomerate resulting in
poorly cemented sands, cobbles and boulders at finish
grade, producing a rough uneven surface. These cut
slopes shall be evaluated in the field by the Project
Engineering Geologist or Geotechnical Engineer.

stabilization fills may be required. Future exploration and in-grading observation could reveal more
favorable geology in these specific areas.
• Alluvium/Colluvium: Cut slopes exposing
alluvial/colluvial soils (Qal) shall require replacement with a drained stabilization fill. Typically, such
corrective grading would be constructed with a
minimum key width corresponding to one-half the full
height of the superjacent slope, but not less than 15
feet. Minimum key depths at the toe shall be 2 feet.
All stabilization fills shall be provided with a
backdrain and outlet system as detailed in Appendix
IV of the Geotechnical Report.
• Silverado Formation: Cut slopes within the Silverado
Formation are expected to be grossly stable; however
the final determination shall be made based on
exposed conditions during grading. Cut slopes within
the Silverado Formation may expose poorly cemented
sands, cobbles and boulders at finish grade, which
would produce a rough uneven surface. These cut
slopes shall be evaluated in the field by the Project
Engineering Geologist or Geotechnical Engineer.
Replacement of those slopes with compacted
stabilization fills may be required.
• Fill Slopes: The majority of fill slopes on the project are designed at a maximum slope ratio of 2:1. The
highest fill slope is approximately 160 feet in height
and located subjacent to Lot 68. Based on the results
of the calculations, the 2:1 fill slopes 160 feet and less in height, when properly constructed with onsite
materials, are expected to be grossly stable, as
designed. Keys shall be constructed at the toe of all fill slopes where unsuitable soil removals do not
accomplish a minimum key width of one-half the slope
height plus bench widths or twenty (20) feet,
whichever is greater. Minimum key depths at the toe

shall be 2 feet. Due to grading limit restrictions,
removals of unsuitable soils beyond the proposed toe
may be limited; therefore, additional slope
maintenance shall be expected in the areas where a
1:1 projection into approved materials cannot be
achieved.
Mitigation Measure GEO-3: Subsurface Drainage.
Canyon subdrains are proposed as depicted on Figures 1
through 7 of the Geotechnical Report and shall consist of 6-inch and 8-inch diameter pipes and shall be
constructed in accordance with the details shown in
Appendix IV of the Geotechnical Report. Final
determination of drain locations shall be made in the
field. Outletting of subdrain systems shall require
coordination with the Project Civil Engineer in
determining suitable facilities to accept to drain water.

Mitigation Measure GEO-4: Overexcavation. Where a
transition of cut and fill occurs across a finished lot, it shall be necessary to overexcavate the bedrock portions and replace it with compacted fill. The depth of bedrock overecavation shall be equal to 1/3 the maximum fill
depth (after removals) on the fill side of the transition.
Anticipated transition lots are shown on figures 1-7 of the geotechnical report. Cut pads shall be overexcavated a
minimum of 5 feet to provide a uniform foundation
material. Some highly expansive soils of the silverado
formation may be encountered at grade in some areas.
Consideration shall be given to increasing the
overexcavation depth to mitigate for highly expansive
soils, if warranted. Difficult excavation with a backhoe can be expected in some street areas. Ginter & associates recommends street overexcavation and replacement with
compacted fill to facilitate utility emplacement in these street areas and driveways. Depths of overexcavation
shall extend one (1) foot below the deepest utility line.

Generation of oversized rock (over 8 inches in maximum
dimension) from excavations in the bedrocks is
anticipated. Oversize rock shall be placed in single file windrows not exceeding three feet in height and six (6) feet in width with a minimum equipment width (15 feet)
separating each windrow or a rock blanket fill not
exceeding two (2) to three (3) feet in height. Large erratic rocks shall be buried individually. Granular fill shall be thoroughly flooded in the rock voids and covered with a minimum two feet compacted fill blanket. Successive
windrows shall be staggered and none shall be placed
within 10 feet of finished grade or closer than 15 feet to compacted fill slope surfaces. Typical rock placement
construction detail is provided in Appendix IV of the
Geotechnical Report. Placement of rock windrows shall
be performed under the observation and
recommendations of the Project Geotechnical Engineer.
Fill materials shall be spread in thin lifts, moisture
conditioned to about 1 to 2 percentage points over
optimum moisture content and compacted to a minimum
of 90 (or 93) percent of the laboratory maximum dry
density as determined in accordance with ASTM Test
Method D-1557. Each lift shall be treated in a like
manner until the desired finished grades are achieved.
The grading contractor shall have suitable and sufficient compaction equipment in operation to achieve the
required compaction. When necessary, earthmoving
equipment may be utilized for compaction or temporarily halted in order to permit adequate compaction of fills.

Mitigation Measure GEO-7: Slope Construction
1. Care shall be taken during grading to prevent spillage of loose materials over slopes to remain natural.
Should loose soil be spilled onto natural slopes by the grading contractor, removal of the loose fill shall be
required.
2. Fill shall be properly benched into firm bedrock or
compacted fill as directed by the Project Engineering
Geologist and/or Geotechnical Engineer during
grading. Typical benching shall include 4-foot
verticals exposing approved, competent material (see
Appendix D – Typical Benching Detail of the
Geotechnical Report).
3. In order to minimize surficial slumps on compacted
fill slopes, the following grading procedures shall be
used:
a) Where possible, fill slopes shall be constructed by
overfilling a minimum of three (3) horizontal feet
and then trimming back to expose the dense
inner core of the slope surface. Compacted fill
slopes shall be back-rolled during construction at
intervals not exceeding four (4) vertical feet.
Care shall be taken to construct the slope in a
workmanlike manner so that it is positioned at its
designed orientation and slope ratio. Achieving a
uniform slope surface by subsequent thin wedge
filling must be avoided. Any add-on correction to
a fill slope shall be done by overfilling the affected
area in horizontal, compacted lifts which must be
benched into the existing fill prism. The overfilled
slope may then be trimmed to the design
gradient.
b) Where fill slopes are planned above natural slopes
and cannot be overfilled and trimmed back, the

slopes shall be rolled for the entire height of the
slope with a sheepsfoot roller and then finished
with a grid roller. If the desired compaction is not
obtained in this manner, a vibratory sheepsfoot
roller may be required. To be most effective, this
equipment shall be anchored and manipulated
from a side-boom tractor. In lieu of a grid roller,
the slope may be track rolled with a John Deere
450, Caterpillar D-8 dozer or equivalent. To
obtain the required compaction and appearance
of the slope face, the soil moisture shall be
maintained at above optimum from the time of
mass filling to the completion of grid rolling.
c) The grading contractor shall take proper care to
avoid spillage of loose material down the face of
the slopes during grading and during drainage
terrace and down-drain construction. Fine
grading operations for benches and down-drains
shall not deposit loose trimmed soils on the
finished slope surfaces. Loose soil materials shall
require removal.
d) Seeding and planting of slopes shall proceed as
rapidly as possible to achieve a well-established
and deep-rooted vegetal cover requiring minimal
watering. The type of vegetation and watering
schedule shall be established by a landscape
architect familiar with hillside maintenance.

Mitigation Measure GEO-10: Foundation Design. The
compacted engineered fill at the project site is anticipated to be low to medium soil expansion potential. Presented below are preliminary geotechnical criteria for design of building foundations, based on medium soil expansion
potential for the on-site soils:
Option 1 - Conventional Footing:
Allowable Bearing Pressure (1) = 1,500 pounds
per square foot (psf)
Minimum Footing Depth (2) = 24 inches
Minimum Footing Width = Continuous: 12
inches
Isolated: 24
inches
Passive Soil Pressure (3) = 250 psf/ft.
Friction Coefficient = 0.30 (ultimate)
Minimum Footing Reinforcement = Four No. 4 bars,
2 each at top and
bottom
Garage Door Grade Beam = 18 inches deep,
Four No. 4 bars,
Two each at top
and bottom, tied
into foundation
elements.
(1) The above value may be increased 250 psf for each
additional foot exceeding the minimum embedment
depth and/or width, subject to a maximum of 2,500
psf. Allowable bearing pressures may be increased
by one-third for short term loading due to wind or
seismic forces.
(2) Footing depth is from lowest adjacent finished soil City of Corona

grade. Footings shall be deepened, as necessary, to
provide setback distance from adjacent slope in
conformance with CBC criteria.
(3) Value applies to level soil condition, and is subject to a maximum of 2000 psf.
Option 2 – Post-Tensioned Foundation:
If post-tensioned slab/footing system is selected for the subject project, the design may be based on the
geotechnical criteria shown below for medium soil
expansion potential. These are based on the guidelines
presented in the PTI, Third Edition design manual.
Thornthwaite Moisture Index = -20
Equilibrium Suction = 3.6
Edge Lift Moisture Variation Distance, em = 5.1
feet
Edge Lift, ym = 1.1
inches
Center Lift Moisture Variation Distance, em = 9.0
feet
Center Lift, ym = 0.47
inches
Minimum Footing Depth (Exterior) = 18
inches below adjacent grade
The above foundation criteria are based on medium soil
expansion consideration only. Foundation design shall
consider anticipated post-construction settlements, as
appropriate. Foundation design details such as slab
thickness, concrete strength, reinforcements, etc. shall be established by the Project Structural Engineer
considering medium soil expansion and settlement
potential provided below.

Mitigation Measure GEO-11: Foundation Settlement.
Total static and differential post-construction settlements for footings designed and constructed in accordance with the criteria given below and supporting loads not
exceeding the typical loadings for residential
construction (column and wall loads on the order of 30
kips and 3 kips/lineal foot, respectively) are not
anticipated to exceed the values shown below. The
settlement estimates shall be confirmed based on review of the foundation plans. Structures shall be designed for the following post-construction settlements:
- Total settlement = 1 inch
- Differential settlement = ¾-inch (*)
(*) Between similarly loaded column footings and for
continuous footings and slabs over a distance of
approximately 30 feet.
General Remarks:
(i) Footing depths shall not be allowed to be affected
adversely, such as through erosion softening, digging,
landscaping, etc.
(ii) Where foundations encroach closer than five (5) feet horizontally from the flow line of drainage swales, the footing shall be deepened sufficiently to maintain the
required embedment depth below the adjacent flow
line.
(iii) Foundation details such as concrete strength,
reinforcements, etc. shall be established by the Project Structural Engineer, considering the loading and
medium soil expansion potential. The footing and slab
reinforcements recommended in the Geotechnical
Report are minimum requirements. More restrictive
criteria based on structural design considerations or

Mitigation Measure GEO-12: Slab-On-Grade.
Recommended Minimum Criteria For Slab-On-Grade Are
Shown Below:
Concrete Floor Slabs: Concrete floor slabs shall be 5
inches thick (minimum) and shall be reinforced with
No. 3 bars at 18 inches on center, each way at mid
height. No. 3 bars at 18 inches on center shall be
provided connecting floor slabs to footings. In order
to minimize migration of moisture up the concrete
slab from soil subgrade and damage to floor coverings,
a moisture barrier/water vapor retarder is
recommended beneath floor slabs as discussed
hereinafter.
Moisture/Water Vapor Retarder for Concrete Slabon-Grade: In order to reduce the potential for moisture/water vapor migration up through the slab
and possibly affecting floor covering, a
moisture/vapor retarder is recommended under
concrete floor slab-on-grade. The moisture barrier
shall be properly installed, lapped and sealed in
accordance with the manufacturer’s specifications.
Punctures and rips shall be repaired prior to
placement of sand. At a minimum, this

moisture/water vapor retarder shall consist of 10-
millimeter thick polyethylene (“Visqueen”), lapped
and sealed, and placed mid-height within a 4-inch
coarse sand layer. This moisture/water vapor
retarder shall be installed in accordance with
manufacturer’s specifications. The following
recommendations are based on the tentative
guidelines by the American Concrete Institute (ACI,
April 2001) to reduce the potential moisture/water
vapor intrusion in concrete slab-on-grade. Based on
Ginter & Associates’ review of available literature, it appears that the ACI procedure would be more
effective to help reduce potential moisture/water
vapor migration up through concrete slab-on-grade.
Recommendations based on the ACI guidelines are
presented below:
• The moisture/water vapor retarder shall consist of
high strength polyethylene membrane and shall meet
or exceed the ASTM: E-1745-97 Class C material
requirements for water vapor permeance, tensile
strength and puncture resistance. The vapor retarder
shall consist of “Moistop Plus” (Fortifiber Building
Products Systems) or “Vapor Block” VB 15
(Americover, Inc.), or approved equal. The vapor
retarder shall be underlain by a capillary break
comprised of minimum 4 inches thick pea gravel layer.
The gravel layer shall be placed and compacted on
approved soil sub-grade.
• The membrane shall be placed on approved gravel
layer and properly lapped and sealed. Membranes
intersecting utility pipes, sewer lines, ducts or drains shall be properly wrapped around the penetrations
and sealed. All punctures and rips in the membrane
shall be repaired prior to placement of concrete,
following manufacturer’s recommendations. The
vapor retarder shall be installed in general accordance City of Corona Skyline Heights Project

with the procedures outlined in ASTM: E-1643, and in
conformance with the installation procedures
recommended by the manufacturer.
• To minimize slab curling, a low slump concrete (low
shrinkage mix design) shall be used for the slab
construction, as determined by the Project Structural
Engineer.
The moisture/water vapor protection for concrete
slab-on-grade shall be selected based on cost and
construction considerations, and considering potential
future problems resulting from improper and
uncontrolled landscape irrigation practices.
Regardless of the moisture/water vapor retarder
option selected, it should be emphasized that proper
control of irrigation and landscape water adjacent to
the structure is of paramount importance.
Mitigation Measure GEO-13: Driveways. Driveway
concrete slabs shall be 5 inches thick (minimum) with no. 3 bars at 18 inches on center, each way at mid-height.
The slab may be placed directly on properly prepared
sub-grade. No moisture barrier is required under
driveway slabs.

Corona, CA 92882
Public Comment Opposing Skyline Heights Project (SP2025-0001 / TTM 36544) Attention Sandra Vanian and the Planning and Housing Commission, I am writing to express my opposition to the proposed Skyline Heights Project (SP2025- 0001 and TTM 36544), scheduled for consideration on May 11, 2026.
While I understand the need for thoughtful development, I have serious concerns about the project's impact on the surrounding community:
First, the existing infrastructure in this area does not appear capable of supporting additional housing at this scale. Roads are already strained and in suboptimal condition, and local schools are overcrowded. Adding more residents without significant infrastructure improvements will only worsen these issues.
TraƯic and safety are also major concerns. Increased vehicle volume on Foothill Parkway, Skyline Drive, and surrounding streets will likely lead to congestion, longer emergency response times, and heightened risks for both drivers and pedestrians.
In addition, the proposed development threatens to eliminate or significantly impact popular hiking and biking trails that are widely used by the community. These outdoor spaces are an important local resource for recreation and quality of life.
I am also concerned about the broader social impacts. New developments of this scale can drive up property values and rents, which may put pressure on longtime residents and small businesses. This kind of displacement and gentrification can fundamentally change a community's character.
The project would also alter the existing neighborhood character, particularly given its hillside location. The visual and aesthetic impacts of large-scale development in this area are significant and should not be overlooked.
Finally, the construction process itself would bring years of disruption, including noise, dust, and potential road closures. While temporary, these impacts would meaningfully reduce the quality of life for nearby residents during that time.
For all these reasons, I respectfully urge the Commission to reconsider or deny this project, or, at a minimum, require substantial modifications to address these concerns.
Thank you for your time and consideration.
Sincerely,
Dean Nelson & Katherine Allgaier
