Basin volume is calculated using the "truncated pyramid" formula, a more conservative estimate than "averaged end areas" so metimes used (Drywell can be "zeroed out" by reducing numbers to less than .001, but should not entered as zeros or program chokes .) Drywell storage includes 40% of the 1' wide rock bed surrounding the drywell: formula (upper)*P10*(diam/2)"2+(lower)*PI()*((diam/2)^2+0.4*((diam/2+(grav+0.4166))"2-(diam/2+0.4166)"2)) The drywell wall thickness is assumed at 5" (0.4166) and the gravel bed width is variable "gray" Drywell design factors Upper sec.

Basin volume is calculated using the " truncated pyramid" formula, a more conservative estimate than "averaged end areas" sometimes used (Drywell can be " zeroed out by reducing numbers to less than .001, but should not entered as zeros or program chokes .) Drywell storage includes 40% of the 1' wide rock bed surrounding the drywell: formula (upper) *PI()*(diam/2)^2+(lower) *PIQ*((diam/2)^2+0.4*((diam/2+(grav+0.4166))^2-(diam/2+0.4166)"2)) The drywell wall thickness is assumed at 5" (0.4166) and the gravel bed width is variable "gray" Drywell design factors Upper sec.

Retention Basin Percolation Rate (in/hr) 1 (also used for drywell percolation rate) Percolation is taken incrementally.

Basin volume is calculated using the "truncated pyramid" formula, a more conservative estimate than "averaged end areas" sometimes used The measured elevation of the underground chamber top and bottom are to be determined. (Drywell can be "zeroed out" by reducing numbers to less than .001, but should not entered as zeros or program chokes.) Drywell storage includes 40% of the 1' wide rock bed surrounding the drywell: formula (upper)*PIQ*(diam/2)^2+(lower)*PIQ*((diam/2)^2+0.4*((diam/2+(grav+0.4166))^2-(diam/2+0.4166)^2)) The drywell wall thickness is assumed at 5" (0.4166) and the gravel bed width is variable "gray" Drywell design factors Upper sec. (ft.)= 0.001 Lower sec. (ft.)= Gravel bed width around drwyell= 1
1001
Ring diam. (ft.) = 0.001 Drywell lower max. (cf)= 0.00 Upper max.(cf)= 0.00 Drywell total(cf)= 0.00
NOTE: The basin top and bottom are defined as the required bed size provided by ADS, and rather than using the actual max depth, the depth has been adjusted for the max. storage to approximately be the provided volume of the chambers after taking the stone space into account. The StormTech fact sheet is provided in Appendix G.

Coordinate System: W eb Mercator (EPSG:3857)
Maps from the W eb Soil Surv ey are based on the W eb Merc ator projection, which preserves direction and shape but distorts distance and area. A projecti on that preserves ar ea, such as the Alb ers equal-area conic projection, should be used if more accurate calculati ons of distanc e or are a are required.

This product is generated from the USDA-NRCS certified data as of the v ersi on d ate(s) list ed b elow .

Soil Survey Area: Riverside County, Coach ella Valley Area, California
Survey Area Data: Version 14, Sep 1, 2022
Soil map units are labeled (as space allows) for map scales 1:50,000 or larger .

Date(s) aerial images were photographed: Mar 15, 2022 —May 28, 2022
The orthophot o or other b as e map on which the soil lines w ere compiled and digitiz ed probably differs from the background imag ery displayed on these maps. As a result, some minor shifting of map unit b oundaries may be evid ent .

Hydrologic soil groups are based on estimates of runoff potential. Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long -duration storms.

The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows:

Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission.

Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture.

These soils have a moderate rate of water transmission.

Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission.

Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink -swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission.

If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes.

It Precipitation frequency (PF) estimates in this table are based on frequency analysis of partial duration series (PDS). 11-1250

Numbers in parenthesis are PF estimates at lower and upper bounds of the 90% confidence interval. The probability that precipitation frequency estimates (for a given duration and average recurrence interval) will be greater than the upper bound (or less than the lower bound) is 5%. Estimates at upper bounds are not checked against probable maximum precipitation (PMP) estimates and may be higher than currently valid PMP values.

Please refer to NOAAAtlas 14 document for more information.

Notes:

1. All runoff index (RI) numbers are for Antecedent Moisture Condition (AMC) II.

2. Quality of cover definitions:

Poor -Heavily grazed or regularly burned areas. Less than 50 per- cent of the ground surface is protected by plant cover or brush and tree canopy.

Fair -Moderate cover with 50 percent to 75 percent of the ground sur- face protected.

Good -Heavy or dense cover with more than 75 percent of the ground surface protected.

3. See Plate C-2 for a detailed description of cover types.

4. Use runoff index numbers based on ground cover type. See discussion under "Cover Type Descriptions" on Plate C-2.

5. Reference Bibliography item 17.

AHC Skilled Nursing Facility
Response to Comments
The City received four comment letters to the Initial Study/Mitigated Negative Declaration for the proposed Project. The following provides individual comments and responses. The complete comments are attached to this response in Appendix A.

Agua Caliente Band of Cahuilla Indians
Letter dated April 22, 2024
Comment 1:

The Agua Caliente Band of Cahuilla Indians (ACBCI) appreciates your efforts to include the Tribal Historic Preservation Office (THPO) in the AHC Skilled Nursing Facility project. We have reviewed the documents and have the following comments:
* The Mitigated Negative Declaration document included standard mitigation measures to address impacts to cultural resources. We found these measures to be sufficient. * At this time the concerns of the ACBCI THPO have been addressed and proper mitigation measures have been proposed to ensure the protection of tribal cultural resources. This letter shall conclude our AB52 consultation efforts.

Again, the Agua Caliente appreciates your interest in our cultural heritage. If you have questions or require additional information, please call me at (760) 423-3485. You may also email me at [email protected].

Response 1:

The City thanks the Agua Caliente for their participation in the CEQA process for this project.

The comments do not require further response, as the Agua Caliente indicate that they are satisfied that the project will mitigate cultural and tribal cultural resource impacts.

Colleen Hamilton
Email dated April 26, 2024
Comment 1:

We have serious concerns about the project, as it will directly impact our enjoyment of the property located at 11 Cassis Circle and the loss of mountain views will undoubtedly lower our property value substantially. When we purchased our property in early 2022, part of our due diligence involved checking with the City of Rancho Mirage and we were given their assurance that the empty lot behind us was zoned for Office Commercial, specifically "single story medical offices" . We checked the guidelines and noted that the maximum height for a single storey building was to be 20 feet, which indicated that our view could never be significantly impacted.

Given that the property was zoned Office Commercial, we understood that the hours of operation would closely resemble business hours. Yet the proposal for the AHC Skilled Nursing Facility 11-1272

AHC Skilled Nursing Facility
Response to Comments

calls for a 24 -hour care center with roof heights of up to 32'10". If this plan is allowed to proceed, we will be impacted significantly in terms of round -the- clock noise, traffic and most of all, reduced mountain views. .

Response 1:

These introductory comments are noted. Responses to specific issues are provided below.

Comment 2:

Specifically, we wish to provide feedback with respect to the following items on the Environmental Checklist and Discussion:

"Less Than Significant Impact" on a scenic vista. The high roof lines shown in the architect's drawings would have a MAJOR impact on our vista, as all but the very tops of the mountains to the west will be obscured from our view if the City of Rancho Mirage allows the developer to exceed the normal height limitation of 20 ft. for a single story building. The setbacks described on page 20 of the document are not sufficient to mitigate the loss of views we currently enjoy and for which we paid top dollar. It is not necessary to have roof lines as high as 24 ft for much of the facility and 32'10" for large portions as well. We understand that the developer wishes for patients and staff at the facility to enjoy high ceilings in their hallways, but these high ceilings and clerestory take the elevation of a single story, as zoned, to over a two story elevation. This will most certainly occur at the expense of the long-term neighbors who would lose their mountain views. That is undoubtedly significant to our enjoyment of our properties and there will be a significant drop in values for the three adjoining properties most directly impacted by these unnecessarily high roof lines.

Most of the medical buildings to the north of this site , whether two story or not, have flat rooves that help with the sight lines for the existing neighbours.

Response 2:

The comment is noted. The ridgelines of the building's roof are 22 to 24 feet (IS, page 5). The tower feature at the center of the building extends to 33'4", and applies to an area equivalent to 8% of the building, not a large portion of the building as stated by the commenter. The building's eastern wing, which is the closest to the commenter's property line, occurs at a distance of approximately 60 feet from the east property line. Further, the building mass is varied, and at 45 degree angles to the property line. The Zoning Ordinance allows building heights to exceed 20 feet, consistent with the provisions of Section 17.20.100, when additional setbacks are provided.

The project's 24 foot ridgelines require an additional 8 foot setback in addition to the 20foot setback required, for a total of 28 feet. Therefore, as it relates to Zoning standards, the project exceeds Zoning requirements.

In relation to the commenter's concern regarding the obstruction of views from their private yard, the Initial Study correctly determines that impacts will be less than significant. The distance to 11-1273

AHC Skilled Nursing Facility
Response to Comments

the closest point of the proposed building is approximately 60 feet, which exceeds the required setbacks. That distance, combined with the angled nature of the building, will result in obstruction of the mid -range mountain slopes for the commenter when viewing directly west, views to the southwest (to the Santa Rosas) and northwest (to the San Gorgonios) will remain, and the tops of the San Jacinto range will be visible above the structure. It is also noted that the medical office buildings described by the commenter rise to a height of 28, 32 and 37 feet, substantially higher than the proposed project, and because of their mass parallel to Bob Hope Drive, result in substantially greater blockage of westerly views. The proposed height for the project is consistent with the City's Zoning Ordinance, which allows increased heights with increased setbacks, and also with the character of other commercial office and institutional properties on the east side of Bob Hope Drive, north of Gerald Ford Drive, which exceed the 20 foot roof height and provide one- and two-story elevations to the street.

The commenter's opinion regarding the property values is noted, but is not a CEQA issue.

Comment 3:

Additionally, the covered parking proposed along the east wall as shown on page 10 will most certainly impede our view and negates the mitigating effect of the 50 ft setback claimed by the developer There is no setback for the covered parking along that wall and it is bound to be higher than the top of the existing wall. It would be far better to have uncovered parking along the east wall.

Response 3:

The carport structures are proposed to be 9'10" in height. The carport roof is parallel to the ground plane, and has no perceptible slope. As a result, the carport roofs, although visible above the perimeter wall, will not result in significant mass for the viewshed. The commenter's opinion regarding the positioning of the carports is noted.

Comment 4:

Perhaps the problem of reducing the neighbors' views could be mitigated by removing more material from the lot and working from a lower elevation. Page 26 of the document provided calls for 32,970 cubic yards of cut and 33,140 cubic yards of fill, which suggests that no effort is being made to lower the elevation and reduce the drastic impact on neighbors' sight lines.

If the City of Rancho Mirage is going to allow the developer to disregard the City's own guidelines for single storey buildings by designing high roof lines, it would seem fair to require the developer to mitigate the impact on neighbors by lowering the grade of the lot.

Response 4:

The commenter's suggestion is noted. Finished grade is determined by a number of factors, but is not a CEQA issue per se. As it relates to the impacts to scenic vistas, please see Response

2. 11-1274

AHC Skilled Nursing Facility
Response to Comments

Comment 5:

We have concerns about the smell, noise and propensity for rodent infestation associated with garbage receptacles located on the east side of the facility, and would prefer that the City require the developer to move the garbage receptacles to the other side of the building, away from our homes. This was suggested and discussed at the meeting held on January 24, but page 10 of the document provided shows the dumpsters have only been moved partially away from the east fence. They are still on the "neighbors' side" of the facility. As proposed at the January 24 meeting, these receptacles could be shielded from view along Bob Hope Drive by trees or another barrier such as that which is used to enclose the generator. Doing so would reduce the noise of slamming metal bins heard as staff access the dumpsters all day and night, and would keep the very loud garbage trucks from disturbing us as early as 7:00 AM or as late as the dinner hour, when residents are using their back yards to cook and serve dinner.

Response 5:

The commenter's opinions are noted, however, there is no substantial evidence that the location of the fully enclosed trash dumpsters at a distance of 120 feet west of the east property line will result in odor, noise or rodent infestation. The project is proposed on a parcel designated Office, and allowing the proposed use. The land use proposed is a skilled nursing facility, which will generate trash similar to residential trash. The project operator will be required to maintain the trash enclosures in a safe and sanitary manner, and the project will be required to contract with Burrtec for regular trash pickup. The commenter's suggestion regarding relocation is noted.

Comment 6:

Similarly, air conditioning units currently shown on rooftops near the east ends of the proposed facility should be positioned closer to the center of the building. and be contained in noise attenuation shielding. This will reduce the noise and visual impact the NC units have on those of us living on the adjacent properties.

Response 6:

The commenter is incorrect. Roof -mounted HVAC units will only occur in the center of the building, to serve common areas. HVAC units for the patient rooms, including the rooms in the wing closest to the commenter, will be mounted below each patient room window. These units serve only the room in which they are located. From the exterior, the units will be screened, both in terms of visibility and noise, by landscape berms and plantings. No significant noise or visual impact will occur.

Comment 7:

While the 24 hour care facility is bound to meet a need in the community and bring in tax revenue to the City, I believe it to be incumbent upon the City to protect the interests of the neighbors who were there first, and purchased property with the understanding that there would be only 20 11-1275

AHC Skilled Nursing Facility
Response to Comments

ft, single storey office commercial buildings constructed on the lot located on the corner of Bob Hope and Gerald Ford Drives.

In conclusion, the City could respect all inhabitants by ensuring that the developers:

1. Lower the roof lines and construct the base at a lower elevation,

2. Eliminate the cover atop parking stalls along the east wall,

3. Relocate the trash receptacles to the west side of the proposed facility, and

4. Relocate NC units from the east ends of wings to a more central location on the building.

Response 7:

The commenter's opinions are noted, but do not raise a new CEQA issue. Responses regarding aesthetic, carport, trash and HVAC impacts are addressed in the responses above. No further response is required.

Imperial Irrigation District
Letter dated May 9, 2024
Comment 1:

On April 15, 2024, the Imperial Irrigation District received from the the City of Rancho Mirage, a Notice of Intent to adopt a Mitigated Negative Declaration for the AHC Skilled Nursing Facility project. The project proposes the construction of a one-story 42,526 sq. ft. 46 -bed skilled nursing facility, a building pad for a future 5,000 to 10,000 sq. ft. medical office building and other site improvements.The approximately 5.75 -acre project site is located at the northeast corner from the intersection of Bob Hope Drive and Gerald Ford Drive (APNs 685-120-003 and -004) in Rancho Mirage, California.

IID has reviewed the project information and has the following comments:

1. Based on the preliminary information provided to the IID, the additional power load to service the proposed project will require the acquisition, design, and construction of a new substation with two (2) 28 MVA 92/13.2 kV transformer banks in addition to transmission and distribution backbone line extensions, distribution getaways and distribution feeders to serve the new substation from existing transmission lines. A standard 315' by 315' site (final site dimensions will be determined once evaluation is completed) pre -approved by IID will be mandatory which should include the appropiate grading, fencing, permits, zoning change, environmental compliance documentation, landscaping (if required by the City), and all rights -of -way and easements for the substation, and access rights for both ingress and egress, as well as for power line facilities.

2. The applicant will be required to extend a minimum of one (1) feeder (conduit and cable) from the new substation to the proposed development. In addition, the applicant will be required to install the necessary conduit/vault systems following the Permanent Plan of Service as well as distribution getaways conduit systems from the new substation. 11-1276

AHC Skilled Nursing Facility
Response to Comments

3. It is important to note that a transmission -level power flow analysis will be developed once a customer project application and plans and loading calculations are received. This detailed information will allow IID to perform an accurate assessment and provide a full report of any potential impacts and mitigation measures. The conditions of service could change as a result of the additional studies. The cost of any additional technical assessment/study shall be borne by the applicant.

4. IID will not begin any engineering studies to provide electrical service to the project until the applicant submits a customer project application (available for download at http://www.iid.com/home/showdocument?id=12923 and detailed loading information, panel sizes, project schedule and estimated in-service date. Applicant shall bear all costs associated with providing electrical service to the project, including but not limited to the construction of the new substation facilities, transmission line extensions, distribution getaways, distribution feeder breakers, feeder backbones and distribution overhead and/or underground line extensions, which, based on current 2024 IID rates, are estimated to be $28 Million (subject to change without notice); as well as the cost of any other related upgrades and applicable permits, zoning changes, landscaping (if required by the County) and rights -of -way and easements.

5. The applicant shall bear the cost of the substation infrastructure to serve the development but may be eligible for reimbursement from a third party user or third party users for a portion of the costs pursuant to existing IID regulations and/or approval by the IID Board of Directors.

6. The applicant should be advised that pursuant to 1ID process, the standard time frame for the implementation of a new substation (engineering, equipment procurement and construction) requires a minimum of 24 months. As a result, the applicant should adjust the project's in-service dates accordingly. The procurement of the new substation banks will commence upon receipt of the customer project application for the substation bank acquisition including payment for the full cost of the required equipment.

7. Line and feeder extensions to serve the project will be made in accordance with IID Regulations:

No. 2 ( http://www.iid.com/home/showdocument?id=2540) , No. 13 ( http://www.iid.com/home/showdocument?id=2553) , No. 15 ( http://www.iid.com/home/showdocument?id=2555)

8. For additional information regarding electrical service for the project, the applicant should be advised to contact the 110 Energy - La Quinta Division Customer Operations, 81-600 Avenue 58 La Quinta, CA 92253, at (760) 398-5841 and speak with the project development planner assigned to the area.

9. It is important to note that IID's policy is to extend its electrical facilities only to those project that have obtained the approval of a city or county planning commission and such other governmental authority or decision -making body having jurisdiction over said developments.

10.The applicant will be required to provide rights of ways and easements for any proposed power line extensions and/or any other infrastructure needed to serve the project as well as the necessary access to allow for continued operation and maintenance of any 11D facilities located on adjoining properties.

11. Public utility easements over all private public roads and additional ten (10) feet in width on both side of the private and public roads shall be dedicated to 110 for the construction, operation, and maintenance of its electrical infrastructure.

12.Any construction or operation on 110 property or within its existing and proposed right of way or easements including but not limited to: surface improvements such as proposed new streets, driveways, parking lots, landscape; and all water, sewer, storm water, or any other above ground or underground utilities; will require an encroachment permit, or encroachment agreement (depending on the circumstances). A copy of the 110 encroachment permit application and instructions for its completion are available at https://www.iid.com/about- iid/department-directory/real-estate. The 110 Real Estate Section should be contacted at (760) 339-9239 for additional information regarding encroachment permits or agreements.

13.Any new, relocated, modified or reconstructed IID facilities required for and by the project (which can include but is not limited to electrical utility substations, electrical transmission and/or distribution lines, ancillary facilities associated with the conveyance of energy service; the acquisition and dedication of real property, rights of way and/or easements for the siting and construction of electrical utility substations, electrical transmission and/or distribution lines and ancillary facilities associated with the conveyance of energy service, etc.) need to be included as part of the project's California Environmental Quality Act (CEQA) and/or National Environmental Policy Act (NEPA documentation, environmental impact analysis and mitigation. Failure to do so will result in postponement of any construction and/or modification of 110 facilities until such time as the environmental documentation is amended and environmental impacts are fully mitigated. Any mitigation necessary as a result of the construction, relocation and/or upgrade of 11D facilities is the responsibility of the project proponent.

14. Dividing a project into two or more pieces and evaluating each piece in a separate environmental document (Piecemealing or Segmenting), rather than evaluating the whole of the project in one environmental document, is explicitly forbidden by CEQA, because dividing a project into a number of pieces would allow a Lead Agency to minimize the apparent environmental impacts of a project by evaluating individual pieces separately, each of which may have a less -than -significant impact on the environment, but which together may result in a significant impact. Segmenting a project may also hinder developing comprehensive mitigation strategies. In general, if an activity or facility is necessary for the operation of a project, or necessary to achieve the project objectives, or a reasonably foreseeable consequence of approving the project, then it should be considered an integral project component that should be analyzed within the environmental analysis. The project description should include all project components, including those that will have to be approved by responsible agencies. The State CEQA Guidelines define a project under CEQA as "the whole of the action" that may result either directly or indirectly in physical changes to 11-1278

the environment. This broad definition is intended to provide the maximum protection of the environment. CEQA case law has established general principles on project segmentation for different project types. For a project requiring construction of offsite infrastructure, the offsite infrastructure must be included in the project description. San Joaquin Raptor/Wildlife Rescue Center v. County of Stanislaus (1994) 27 Cal.App. 4th 713.

15. It is important to bear in mind that to address the project impacts to the electrical utility (i.e., the IID electrical grid), considered under the environmental factor "Utilities and Services" of the Environmental Checklist/Intial Study, to determine if the project would require or result in the relocation or construction of new or expanded electric power facilities, the construction or relocation of which could cause significant environmental effects; a circuit study/distribution impact study, facility study, and/or system impact study must be performed.

16.Applicant should be advised that landscaping can be dangerous if items are planted too close to 11 D's electrical equipment. In the event of an outage, or equipment failure, it is vital that 11D personnel have immediate and safe access to its equipment to make the needed repairs.

For public safety, and that of the electrical workers, it is important to adhere to standards that limit landscaping around electrical facilities. 11D landscaping guidelines are available at https://www.iid.com/energy/vegetation-management .

The comments are noted. Most relate to improvement requirements, and are not CEQA issues.

The commenter's need for a substation is a regional issue, and does not pertain directly to the CEQA analysis in the Initial Study. The project is not responsible for the analysis of a regional facility. The City will condition the project to demonstrate that it has electricity available prior to the issuance of a building permit for the facility, as it would for any development project.

CDFW ROLE
CDFW is California's Trustee Agency for fish and wildlife resources and holds those resources in trust by statute for all the people of the State. (Fish & G. Code, §§ 711.7, subd. (a) & 1802; Pub. Resources Code, § 21070; CEQA Guidelines § 15386, subd. (a).) CDFW, in its trustee capacity, has jurisdiction over the conservation, protection, and management of fish, wildlife, native plants, and habitat necessary for biologically sustainable populations of those species. (Id., § 1802.) Similarly, for purposes of CEQA, CDFW is charged by law to provide, as available, biological expertise during public agency environmental review efforts, focusing specifically on Projects and related activities that have the potential to adversely affect fish and wildlife resources.

CDFW is also submitting comments as a Responsible Agency under CEQA. (Pub. Resources Code, § 21069; CEQA Guidelines, § 15381.) CDFW expects that it may need to exercise regulatory authority as provided by the Fish and Game Code. As proposed, for example, the Project may be subject to CDFW's lake and streambed alteration regulatory authority. (Fish & G. Code, § 1600 et seq.) Likewise, to the extent implementation of the Project as proposed may result in "take" as defined by State law of any species protected under the California Endangered Species Act (CESA) (Fish & G. Code, § 2050 et seq.), the Project proponent may seek related take authorization as provided by the Fish and Game Code.

PROJECT DESCRIPTION SUMMARY
Proponent: Prest Vuksic Greenwood Architects
Objective: The proposed Project is the construction of a one-story, 42,526 -square -foot skilled nursing facility. The second phase of development would result in a medical office building, between 5,000 and 10,000 square feet, on the southern portion of the site, adjacent to Gerald Ford Drive. The second medical office building is not currently proposed and will be designed and entitled following the skilled nursing facility. At buildout, the proposed skilled nursing facility and future medical office building would provide a total of 122 parking stalls, including 10 ADA spaces, 4 EV charging stalls, and 54 covered carport spaces. Landscaped area (12,432 square feet) will be provided on- site, featuring drought -tolerant plant species and a water -efficient drip irrigation system. A four -foot wall will line the site along its northern, southern, and western boundaries. The Project will be set back from Gerald Ford Drive and Bob Hope Drive by a minimum of 25 feet.

Location: The proposed Project is an approximately 5.75 -acre site located at the northeast corner from the intersection of Bob Hope Drive and Gerald Ford Drive in the City of Rancho Mirage (Assessor's Parcel Numbers 685-120-003 and 685-120-004).

Timeframe: Construction is expected to begin in 2024 and continue through 2025.

COMMENTS AND RECOMMENDATIONS
CDFW has jurisdiction over the conservation, protection, and management of fish, wildlife, native plants, and habitat necessary for biologically sustainable populations of those species (i.e., biological resources). CDFW offers the comments and recommendations below to assist the City in adequately identifying and/or mitigating the Project's significant, or potentially significant, direct and indirect impacts on fish and wildlife (biological) resources. The MND has not adequately identified and disclosed the Project's impacts (i.e., direct, indirect, and cumulative) on biological resources and whether those impacts are reduced to less than significant.

CDFW's comments and recommendations on the MND are explained in greater detail below and summarized here. CDFW is concerned that the MND does not adequately identify or mitigate the Project's significant, or potentially significant, impacts to biological resources. CDFW also concludes that the MND lacks sufficient information to facilitate a meaningful review by CDFW, including a complete and accurate assessment of biological resources on the Project site. CDFW requests that additional information and analyses be added to a revised MND, along with avoidance, minimization, and mitigation measures that avoid or reduce impacts to less than significant.

Response 2:

The comment is noted. The comments are broad and unsupported, and incorrectly conclude that the Initial Study is inadequate. Individual responses to the issues summarized by the commenter are provided below.

Comment 3:

Existing Environmental Setting
Compliance with CEQA is predicated on a complete and accurate description of the environmental setting that may be affected by the proposed Project. CDFW is concerned that the assessment of the existing environmental setting has not been adequately analyzed in the MND. CDFW is concerned that without a complete and accurate description of the existing environmental setting, the MND may provide an incomplete analysis of Project -related environmental impacts.

The MND Tacks a complete assessment of biological resources within the Project site and surrounding area specifically as it relates to special status plant species. A complete and accurate assessment of the environmental setting and Project -related impacts to special status plant species is needed to both identify appropriate avoidance, minimization, and mitigation measures and demonstrate that these measures reduce Project impacts to less than significant. 11-1281

Response 3:

The comment is overbroad, and provides no substantial evidence regarding the impacts to special status plants. The Initial Study (IS) provides a complete analysis of biological resources and impacts to plant species. See Response 5 for specific details regarding special status plants.

Comment 4:

Mitigation Measures
CEQA requires that an MND include mitigation measures to avoid or reduce significant impacts.

CDFW is concerned that the mitigation measures proposed in the MND are not adequate to avoid or reduce impacts to biological resources to below a level of significance. To support the City in ensuring that Project impacts to biological resources are reduced to less than significant, CDFW recommends adding mitigation measures for special -status plants and the Coachella Valley Multiple Species Habitat Conservation Plan (CVMSHCP), as well as revising the mitigation measures for nesting birds and burrowing owl.

Assessment of biological resources

have the potential to occur on the Project site: Chaparral sand -verbena [(Abronia villosa var. aurita)], Borrego milk -vetch [(Astragalus lentiginosus var. borreganus)], pointed dodder [(Cuscuta californica)], glandular ditaxis [(Ditaxis claryana)], California ditaxis [(Ditaxis serrata var. californica)], Abram's spurge [(Euphorbia abramsiana)], Arizona spurge [(Euphorbia arizonica)], flat -seeded spurge [(Euphorbia platysperma)], ribbed cryptantha [(Johnstonella costata)], and slender cottonheads [(Nemacaulis denudata)]. None of these species were detected on -site during the field assessment, however the assessment was conducted outside of the blooming period." Page 7 of the Project's Biological Resources Assessment dated October 4, 2023 (Biological Assessment), indicates that the field assessment was conducted over a 45 - minute period "between the hours of 1215 and 1300 on 23 July 2023." Section 15125(c) of the CEQA Guidelines states that knowledge of the regional setting of a Project is critical to the assessment of environmental impacts, that special emphasis should be placed on environmental resources that are rare or unique to the region, and that significant environmental impacts of the proposed Project are adequately investigated and discussed. Because the field assessment was conducted outside of the estimated bloom periods for Borrego milk -vetch, glandular ditaxis, Abrams' spurge, Arizona spurge, ribbed cryptantha, and slender cottonheads, it is uncertain if any individuals or significant populations of these species exist within the 5.75 -acre Project site.

time(s) of the year is an important step in adequately disclosing potential impacts to special - status native plants and sensitive natural communities. CDFW's Protocols for Surveying and Evaluating Impacts to Special Status Native Plant Populations and Sensitive Natural Communities2 provides the following guidance on timing and number of visits: "Conduct botanical field surveys in the field at the times of year when plants will be both evident and identifiable. Usually this is during flowering or fruiting. Space botanical field survey visits throughout the growing season to accurately determine what plants exist in the project area.

This usually involves multiple visits to the project area (e.g., in early, mid, and late -season) to capture the floristic diversity at a level necessary to determine if special status plants are present.3 The timing and number of visits necessary to determine if special status plants are present is determined by geographic location, the natural communities present, and the weather patterns of the year(s) in which botanical field surveys are conducted." Importantly, the findings of appropriate botanical field surveys for special -status native plants and sensitive natural communities are important in informing appropriate avoidance, minimization, and mitigation measures and supporting the City in demonstrating that Project impacts are reduced to less than significant.

CDFW recommends that the City include in a revised MND the results of a thorough floristic - based assessment of special -status plants and natural communities performed by a qualified biologist and following CDFW's Protocols for Surveying and Evaluating Impacts to Special - Status Native Plant Populations and Sensitive Natural Communities (CDFW 2018 or most recent version). Based on findings from a recent floristic -based assessment, CDFW recommends that the MND is revised to include an analysis of direct, indirect, and cumulative impacts to biological resources and identification of appropriate avoidance, minimization, and mitigation measures.

CDFW also recommends that City add the following mitigation measure in bold to a revised MND:

Mitigation Measure B10 -[A]: Special -Status Plants
Prior to Project construction activities, a thorough, recent, floristic -based assessment of special status plants and natural communities, following CDFW's Protocols for Surveying and Evaluating Impacts to Special Status Native Plant Populations and Sensitive Natural Communities (see https://wildlife.ca.qov/Conservation/Plants) shall be performed by a qualified biologist. Should any species of native plants designated as rare, threatened, or endangered by state law (excluding CVMSHCP Covered Species) be present in the Project area, on -site or off -site habitat restoration (whichever is applicable) and/or enhancement and preservation should be evaluated and discussed in detail. Where habitat preservation is not available on -site, off -site land acquisition, management, and preservation should be evaluated.

substantial evidence that if any individuals of these species occur, their elimination cause the greater population of the species to drop to less than self-sustaining levels, as described under Fish and Game Code. Finally, the Initial Study and Biological Resource Study both correctly describe the site as small, isolated and disturbed, all of which contribute to the determination that the site is unlikely to support the species in question. The Initial Study correctly characterized potential impacts to unlisted plant species, and no change or mitigation is required.

Comment 6:

Nesting Birds
It is the Project proponent's responsibility to comply with all applicable laws related to nesting birds and birds of prey. Fish and Game Code sections 3503, 3503.5, and 3513 afford protective measures as follows: section 3503 states that it is unlawful to take, possess, or needlessly destroy the nest or eggs of any bird, except as otherwise provided by Fish and Game Code or any regulation made pursuant thereto. Fish and Game Code section 3503.5 makes it unlawful to take, possess, or destroy any birds in the orders Falconiformes or Strigiformes (birds -of -prey) or to take, possess, or destroy the nest or eggs of any such bird except as otherwise provided by Fish and Game Code or any regulation adopted pursuant thereto. Fish and Game Code section 3513 makes it unlawful to take or possess any migratory nongame bird except as provided by rules and regulations adopted by the Secretary of the Interior under provisions of the Migratory Bird Treaty Act of 1918, as amended (16 U.S.C. § 703 et seq.).

therefore, a pre -construction survey will be required to avoid impacts to nesting birds covered by the MBTA and to burrowing owls." The Project site contains sparse cover of shrubs, predominantly creosote (Larrea tridentata), which can support nesting birds. Mitigation Measure BIO-3, in the MND, indicates that if "Project -related disturbance (i.e., grading, vegetation removal, operation of heavy equipment, construction, etc.) cannot be avoided during the nesting season (February 1 to August 31), then a nesting bird clearance survey must be conducted by a qualified ornithologist or biologist immediately prior to scheduled on -site disturbance." CDFW considers Mitigation Measure BIO-3 to be insufficient in scope and timing to reduce impacts to nesting birds to a level less than significant. CDFW is concerned about impacts to nesting birds including loss of nesting/foraging habitat and potential take from ground- disturbing activities and construction. Conducting work outside the peak nesting season is an important avoidance and minimization measure. CDFW also recommends the completion of nesting bird surveys regardless of the time of year to ensure that impacts to nesting birds are avoided. The timing of the nesting season varies greatly depending on several factors, such as bird species, weather conditions in any given year, and long- term climate changes (e.g., drought, warming, etc.). In response to warming, birds have been reported to breed earlier, thereby reducing temperatures that nests are exposed to during breeding and tracking shifts in availability of resources (Socolar et al., 20174). CDFW staff have observed that climate change conditions may result in nesting bird season occurring earlier and later in the year than historical nesting season dates. CDFW recommends that disturbance of occupied nests of migratory birds and raptors within the Project site and surrounding area be avoided any time birds are nesting on- site. CDFW therefore 11-1284

AHC Skilled Nursing Facility
Response to Comments

recommends the completion of nesting bird surveys regardless of the time of year to ensure compliance with all applicable laws pertaining to nesting and migratory birds.

CDFW recommends that the City revise Mitigation Measure BIO-3 with the following additions in bold and removals in strikethrough:

Mitigation Measure BIO-3: Nesting Birds
To the extent feasible, Project -related disturbance (i.e., grading, vegetation removal, operation of heavy equipment, construction, etc.) will be scheduled outside of the peak bird nesting season, which takes place from approximately February 1 through September 15. Regardless of the time of year, nesting bird surveys shall be performed by a qualified avian biologist no more than 3 days prior to vegetation removal or ground - disturbing activities. Pre -construction surveys shall focus on both direct and indirect evidence of nesting, including nest locations and nesting behavior. The qualified avian biologist will make every effort to avoid potential nest predation as a result of survey and monitoring efforts. If active nests are found during the pre -construction nesting bird surveys, a qualified biologist shall establish an appropriate nest buffer to be marked on the ground. Nest buffers are species specific and shall be at least 300 feet for passerines and 500 feet for raptors. A smaller or larger buffer may be determined by the qualified biologist familiar with the nesting phenology of the nesting species and based on nest and buffer monitoring results. Construction activities may not occur inside the established buffers, which shall remain on site until a qualified biologist determines the young have fledged or the nest is no longer active. Active nests and adequacy of the established buffer distance shall be monitored daily by the qualified biologist until the qualified biologist has determined the young have fledged or the Project has been completed. The qualified biologist has the authority to stop work if nesting pairs exhibit signs of disturbance. If Project related disturbance (i.e., grading, vegetation removal, operation of heavy equipment, construction, etc.) cannot be avoided during the nesting season {February 1 to August 31), then a nesting bird clearance survey must be conducted by a qualified ornithologist or biologist immediately prior to scheduled on -site disturbance. If nesting birds are fo nd nn_work buffers f abo it 100 to 30 e t f sted songbirds and 500 feet for listed songbirds and raptors must be established and monitored until young have fledged.

Pursuant to the CEQA Guidelines, section 15097(f), CDFW has prepared a draft mitigation monitoring and reporting program (MMRP) for revised MM BIO-1 and MM BIO-2 as well as CDFW-recommended MM B10 -[A], MM BIO-[B], MM B10 -[C], and MM B10 -[D].

The comment is noted. However, the commenter appears to imply that birds may nest on the site outside of the established nesting period, without providing substantial evidence. The City's responsibility is to assure that nesting birds are not disturbed. Mitigation Measure BIO-3 provides that assurance, and establishes performance standards if birds are nesting on the site. The Initial Study mitigates impacts to nesting bird species to less than significant levels as written. The 11-1285

mitigation measure and the Initial Study correctly protect nesting birds, and do not require amendment.

Comment 7:

Burrowing Owl
Burrowing owl is a California Species of Special Concern. Take of individual burrowing owls and their nests and eggs is defined by Fish and Game Code section 86, and prohibited by sections 3503, 3503.5, and 3513. Fish and Game Code section 3513 makes it unlawful to take or possess any migratory nongame bird except as provided by rules and regulations adopted by the Secretary of the Interior under provisions of the Migratory Bird Treaty Act of 1918, as amended (16 U.S.C. § 703 et seq.). Take is defined in Fish and Game Code section 86 as "hunt, pursue, catch, capture or kill, or attempt to hunt, pursue, catch, capture or kill." Permittes of the CVMSHCP must ensure that Covered Activities within their jurisdictions —both inside and outside Conservation Areas —do not result in the take of the burrowing owl individuals, nests, or eggs. Per Section 3.5.6 of the California Department of Fish and Wildlife (CDFW) Natural Community Conservation Plan (NCCP) Permit #2835-2008-001-06 for the CVMSHCP, "take outside of Conservation Areas will be consistent with sections 3503 and 3503.5 of the Fish and Game Code." Adding further clarification, Section 3.5.6 of CDFW's NCCP Permit indicates that "following all laws applicable to migratory birds (discussed below), the pairs or individuals will not be Taken, just the land around and including the burrows", and "the HCP/NCCP does not authorize Take of nests and eggs as prohibited by Fish and Game Code sections 3503 and 3503.5 and therefore avoidance measures will have to be undertaken for all projects which have breeding burrowing owls present." An activity that results in the take of burrowing owl individuals, nests, or eggs would be unlawful and would not be a Covered Activity under the CVMSHCP. Per Section 13.2 of the CVMSHCP Implementing Agreement, County and Cities obligations include, but are not limited to, taking "all necessary and appropriate actions, following applicable land use permit enforcement procedures and practices, to enforce the terms of project approvals for public and private projects, including compliance with the MSHCP, the Permits and this Agreement." The City has an obligation under the CVMSHCP to ensure the Project does not result in the take of burrowing owl individuals, nests, and eggs.

sign thereof, were not observed or detected on -site during the assessment, potentially suitable habitat (i.e., sparse Sonoran creosote bush scrub) remains present (Appendix D). No burrows of sufficient size were observed on -site at the time of the assessment (only small invertebrate, lizard and/or rodent burrows were observed). The site is relatively small (6 acres) and surrounded on all sides by existing and on -going development, which has isolated the biological resources on -site from any other available undeveloped open space, which further reduces the overall likelihood of burrowing owl occurring on -site." In California, preferred habitat for burrowing owl is generally typified by short, sparse vegetation with few shrubs,5 and that burrowing owls may occur in ruderal grassy fields, vacant lots, and pastures if the vegetation structure is suitable and there are useable burrows and foraging habitat proximity.6 Based on review of aerial imagery, the Project site contains sparse vegetation cover and provides suitable 11-1286

Response to Comments

habitat for burrowing owl. The Project site is located near disturbed open areas to the south and an open space area located approximately 220 meters to the southwest that may support burrowing and foraging habitat for burrowing owls; burrowing owls have been found to concentrate foraging efforts within 600 meters of a nest burrow in southern California7. In addition, burrowing owls frequently move into disturbed areas prior to and during construction activities since they are adapted to highly modified habitats8,9. Suitable habitat for burrowing owl exists within the Project site and within nearby disturbed areas to the south and open space areas to the southwest, and burrowing owls have the potential to move onto the site prior to and during construction activities.

Although the MND includes Mitigation Measure BIO-2 for burrowing owl, CDFW considers the measure to be insufficient in scope and timing to reduce impacts to a level less than significant.

CDFW recommends that the City revise Mitigation Measure BIO-2 with the following additions in bold and removals in strikethrough:

Mitigation Measure BIO-1: Burrowing Owl Surveys
Suitable burrowing owl habitat has been confirmed on the site; therefore, focused burrowing owl surveys shall be conducted by a qualified biologist according to the Staff Report on Burrowing Owl Mitigation prior to vegetation removal or ground -disturbing activities. If burrowing owls are detected during the focused surveys, the qualified biologist and Project proponent shall begin coordination with CDFW and USFWS immediately, and shall prepare a Burrowing Owl Plan that shall be submitted to CDFW for review and approval prior to commencing Project activities. The Burrowing Owl Plan shall describe proposed avoidance, minimization, mitigation, and monitoring actions. The Burrowing Owl Plan shall include the number and location of occupied burrow sites, acres of burrowing owl habitat that will be impacted, details of site monitoring, and details on proposed buffers and other avoidance measures if avoidance is proposed. If impacts to occupied burrowing owl habitat or burrow cannot be avoided, the Burrowing Owl Plan shall also describe minimization and relocation actions that will be implemented.

Proposed implementation of burrow exclusion and closure should only be considered as a last resort, after all other options have been evaluated as exclusion is not in itself an avoidance, minimization, or mitigation method and has the possibility to result in take. If impacts to occupied burrows cannot be avoided, information shall be provided regarding adjacent or nearby suitable habitat available to owls along with proposed relocation actions. The Project proponent shall implement the Burrowing Owl Plan following CDFW and USFWS review and approval.

Preconstruction burrowing owl surveys shall be conducted no less than 14 days prior to the start of Project -related activities and within 24 hours prior to ground disturbance, in accordance with the Staff Report on Burrowing Owl Mitigation (2012 or most recent version). Preconstruction surveys should be performed by a qualified biologist following the recommendations and guidelines provided in the Staff Report on Burrowing Owl Mitigation. If the preconstruction surveys confirm occupied burrowing owl habitat, Project activities shall be immediately halted. The qualified biologist shall coordinate with CDFW and prepare a Burrowing Owl Plan that shall be submitted to CDFW and USFWS 11-1287

The project is not located adjacent to open space areas. The project occurs on two major arterial roadways in Rancho Mirage's urban core. The commenter provides no evidence to contradict the professional biologist's statement that no owl, sign or appropriate burrows are located on the site. The Initial Study requires, in Mitigation Measure BIO-2, pre -construction surveys, in conformance with CDFW protocol. The Initial Study therefore fully acknowledges the Department's requirements. It further requires that they be implemented prior to initiation of construction, which is the appropriate protocol for sites where no individuals, sign or burrows have previously been identified. The City is aware that the species could move onto the site prior to construction, and has provided the appropriate mitigation to protect the species from take.

The mitigation measure is appropriate and complete, lists performance standards should the species be identified, and no further amendment is required.

thus is required to pay the land development/mitigation fee". Section 5.2.1.1 of the CVMSHCP indicates that "Local jurisdictions will impose a mitigation fee on new Development within the Plan Area that impacts vacant land containing Habitat for the Covered Species or any of the conserved natural communities in the Plan through adoption, or amendment of an existing fee ordinance." The Project site contains suitable habitat for burrowing owl and other CVMSHCP Covered Species as further discussed on page 30 of the MND; therefore, the City is required to impose a local development fee for the Project. To document this obligation, CDFW recommends the City add the following mitigation measure to a revised MND:

Mitigation Measure BIO-[B]: CVMSHCP Compliance
Prior to construction and issuance of any grading permit, the City of Rancho Mirage shall ensure compliance with the Coachella Valley Multiple Species Habitat Conservation Plan (CVMSHCP) and its associated Implementing Agreement and shall ensure the collection of payment of the CVMSHCP Local Development Mitigation Fee and transfer of revenues to the Coachella Valley Conservation Commission.

The comment is noted. However, as allowed under CEQA, requirements of law are not mitigation measures, and are assumed to be implemented. Because the payment of the CVMSHCP fee is a requirement by the City, as stated in the Initial Study, its payment will reduce impacts to less than significant levels, and no mitigation measure is required.

species and an efficient drip irrigation system." No other details are provided in the MND on the Project's proposed landscaping plans. CDFW recommends incorporation of water -wise concepts in any Project landscape design plans. In particular, CDFW recommends xeriscaping with locally native California species and installing water -efficient and targeted irrigation systems (such as drip irrigation). Native plants support butterflies, birds, reptiles, amphibians, small mammals, bees, and other pollinators that evolved with those plants. More information on native plants suitable for the Project location and nearby nurseries is available at Calscape:
https://calscape.org/ . Local water agencies/cities and resource conservation cities in your area may be able to provide information on plant nurseries that carry locally native species, and some facilities display drought -tolerant locally native species demonstration gardens. Information on drought -tolerant landscaping and water -efficient irrigation systems is available on California's Save our Water website: https://saveourwater.com/ . CDFW also recommends that the MND include recommendations regarding landscaping from Section 4.0 of the CVMSHCP "Table 4- 112: Coachella Valley Native Plants Recommended for Landscaping" (pp. 4-180 to 4-182; https://cvmshcp.org/plan-documents/) .

Response 9:

The comment is noted. As stated on page 5 and 52 of the Initial Study, the Project is required to comply with the City's water efficient landscaping standards, which includes water budgeting for landscaped areas. The Project will therefore be regulated to assure low water use in landscaping, as clearly stated in the Initial Study.

ENVIRONMENTAL DATA
CEQA requires that information developed in environmental impact reports and negative declarations be incorporated into a database which may be used to make subsequent or supplemental environmental determinations. (Pub. Resources Code, § 21003, subd. (e).) Accordingly, please report any special status species and natural communities detected during Project surveys to the California Natural Diversity Database (CNDDB).

ENVIRONMENTAL DOCUMENT FILING FEES
The Project, as proposed, would have an impact on fish and/or wildlife, and assessment of environmental document filing fees is necessary. Fees are payable upon filing of the Notice of Determination by the Lead Agency and serve to help defray the cost of environmental review by CDFW. Payment of the environmental document filing fee is required in order for the underlying Project approval to be operative, vested, and final. (Cal. Code Regs, tit. 14, § 753.5; Fish & G.

Code, § 711.4; Pub. Resources Code, § 21089.)

CONCLUSION
CDFW appreciates the opportunity to comment on the MND to assist the City in identifying and mitigating Project impacts to biological resources. CDFW concludes that the MND does not adequately identify or mitigate the Project's significant, or potentially significant, impacts to biological resources. CDFW also concludes that the MND Tacks sufficient information for a meaningful review of impacts to biological resources, including an assessment of impacts associated with special status plants. The CEQA Guidelines indicate that recirculation is required when a new significant effect is identified and additional mitigation measures are necessary (§ 15073.5). CDFW recommends that the MND is revised to include a complete assessment of biological resources (special status plants), and that the MND is recirculated for public comment.

CDFW also recommends that revised and additional mitigation measures and analysis as described in this letter be added to a revised MND.

CDFW personnel are available for consultation regarding biological resources and strategies to avoid and minimize impacts. Questions regarding this letter or further coordination should be directed to Jacob Skaggs, Senior Environmental Scientist Specialist, at [email protected].

Response 10:

As demonstrated above, the Initial Study is complete and accurate, and adequately mitigates all impacts to biological resources. The commenter provides no new substantial evidence that any new impact exists, or that identified mitigation measures will not be sufficient to reduce impacts to less than significant levels.

The City thanks the Department for its comments and will continue to assure that it and its applicants comply with Department requirements and State law, including environmental data and filing fees.

Hello, Ben. The following are our written comments on the Draft Mitigated Negative Declaration.

We have serious concerns about the project, as it will directly impact our enjoyment of the property located at 11 Cassis Circle and the loss of mountain views will undoubtedly lower our property value substantially. When we purchased our property in early 2022, part of our due diligence involved checking with the City of Rancho Mirage and we were given their assurance that the empty lot behind us was zoned for Office Commercial, specifically "single story medical offices" . We checked the guidelines and noted that the maximum height for a single storey building was to be 20 feet, which indicated that our view could never be significantly impacted. Given that the property was zoned Office Commercial, we understood that the hours of operation would closely resemble business hours. Yet the proposal for the AHC Skilled Nursing Facility calls for a 24 -hour care center with roof heights of up to 32'10".

If this plan is allowed to proceed, we will be impacted significantly in terms of round-the- clock noise, traffic and most of all, reduced mountain views. .

Specifically, we wish to provide feedback with respect to the following items on the Environmental Checklist and Discussion:

have "Less Than Significant Impact" on a scenic vista. The high roof lines shown in the architect's drawings would have a MAJOR impact on our vista, as all but the very tops of the mountains to the west will be obscured from our view if the City of Rancho Mirage allows the developer to exceed the normal height limitation of 20 ft. for a single story building. The setbacks described on page 20 of the document are not sufficient to mitigate the loss of views we currently enjoy and for which we paid top dollar. It is not necessary to have roof lines as high as 24 ft for much of the facility and 32' 10" for large portions as well. We understand that the developer wishes for patients and staff at the facility to enjoy high ceilings in their hallways, but these high ceilings and clerestory take the elevation of a single story, as zoned, to over a two story elevation.This will most certainly occur at the expense of the long-term neighbors who would lose their mountain views. That is undoubtedly significant to our enjoyment of our properties and there will be a significant drop in values for the three adjoining properties most directly impacted by these unnecessarily high roof lines.

Most of the medical buildings to the north of this site , whether two story or not, have flat rooves that help with the sight lines for the existing neighbours.

Additionally, the covered parking proposed along the east wall as shown on page 10 will most certainly impede our view and negates the mitigating effect of the 50 ft setback claimed by the developer There is no setback for the covered parking along that wall and it is bound to be higher than the top of the existing wall. It would be far better to have uncovered parking along the east wall.
11-1293

Perhaps the problem of reducing the neighbors' views could be mitigated by removing more material from the lot and working from a lower elevation. Page 26 of the document provided calls for 32,970 cubic yards of cut and 33,140 cubic yards of fill, which suggests that no effort is being made to lower the elevation and reduce the drastic impact on neighbors' sight lines.

If the City of Rancho Mirage is going to allow the developer to disregard the City's own guidelines for single storey buildings by designing high roof lines, it would seem fair to require the developer to mitigate the impact on neighbors by lowering the grade of the lot.

We have concerns about the smell, noise and propensity for rodent infestation associated with garbage receptacles located on the east side of the facility, and would prefer that the City require the developer to move the garbage receptacles to the other side of the building, away from our homes. This was suggested and discussed at the meeting held on January 24, but page 10 of the document provided shows the dumpsters have only been moved partially away from the east fence. They are still on the "neighbors' side" of the facility. As proposed at the January 24 meeting, these receptacles could be shielded from view along Bob Hope Drive by trees or another barrier such as that which is used to enclose the generator. Doing so would reduce the noise of slamming metal bins heard as staff access the dumpsters all day and night, and would keep the very loud garbage trucks from disturbing us as early as 7:00 AM or as late as the dinner hour, when residents are using their back yards to cook and serve dinner.

Similarly, air conditioning units currently shown on rooftops near the east ends of the proposed facility should be positioned closer to the center of the building. and be contained in noise attenuation shielding. This will reduce the noise and visual impact the A/C units have on those of us living on the adjacent properties.

While the 24 hour care facility is bound to meet a need in the community and bring in tax revenue to the City, I believe it to be incumbent upon the City to protect the interests of the neighbors who were there first, and purchased property with the understanding that there would be only 20 ft, single storey office commercial buildings constructed on the lot located on the corner of Bob Hope and Gerald Ford Drives.

In conclusion, the City could respect all inhabitants by ensuring that the developers:

1. Lower the roof lines and construct the base at a lower elevation,

2. Eliminate the cover atop parking stalls along the east wall,

3. Relocate the trash receptacles to the west side of the proposed facility, and

4. Relocate A/C units from the east ends of wings to a more central location on the building.

Thank you for your consideration of these requests.

SUBJECT: NOI to Adopt an MND for the AHC Skilled Nursing Facility Project Rancho Mirage, CA
Dear Mr. Torres:

On April 15, 2024, the Imperial Irrigation District received from the the City of Rancho Mirage, a Notice of Intent to adopt a Mitigated Negative Declaration for the AHC Skilled Nursing Facility project. The project proposes the construction of a one-story 42,526 sq. ft. 46 -bed skilled nursing facility, a building pad for a future 5,000 to 10,000 sq. ft. medical office building and other site improvements.The approximately 5.75 -acre project site is located at the northeast corner from the intersection of Bob Hope Drive and Gerald Ford Drive (APNs 685-120-003 and -004) in Rancho Mirage, California.

IID has reviewed the project information and has the following comments:

1. Based on the preliminary information provided to the IID, the additional power load to service the proposed project will require the acquisition, design, and construction of a new substation with two (2) 28 MVA 92/13.2 kV transformer banks in addition to transmission and distribution backbone line extensions, distribution getaways and distribution feeders to serve the new substation from existing transmission lines. A standard 315' by 315' site (final site dimensions will be determined once evaluation is completed) pre -approved by IID will be mandatory which should include the appropiate grading, fencing, permits, zoning change, environmental compliance documentation, landscaping (if required by the City), and all rights -of -way and easements for the substation, and access rights for both ingress and egress, as well as for power line facilities.

2. The applicant will be required to extend a minimum of one (1) feeder (conduit and cable) from the new substation to the proposed development. In addition, the applicant will be required to install the necessary conduit/vault systems following the Permanent Plan of Service as well as distribution getaways conduit systems from the new substation.

3. It is important to note that a transmission -level power flow analysis will be developed once a customer project application and plans and loading calculations are received. This detailed information will allow IID to perform an accurate assessment and provide a full report of any potential impacts and mitigation measures. The conditions of service could change as a result of the additional studies. The cost of any additional technical assessment/study shall be borne by the applicant.

4. IID will not begin any engineering studies to provide electrical service to the project until the applicant submits a customer project application (available for download at http://www.iid.com/home/showdocument?id=12923 and detailed loading information, panel sizes, project schedule and estimated in-service date. Applicant shall bear all costs associated with providing electrical service to the project, including but not limited to the construction of the new substation facilities, transmission line extensions, distribution getaways, distribution feeder breakers, feeder backbones and distribution overhead and/or underground line extensions, which, based on current 2024 IID rates, are estimated to be $28 Million (subject to change without notice); as well as the cost of any other related upgrades and applicable permits, zoning changes, landscaping (if required by the County) and rights -of -way and easements.

5. The applicant shall bear the cost of the substation infrastructure to serve the development but may be eligible for reimbursement from a third party user or third party users for a portion of the costs pursuant to existing IID regulations and/or approval by the IID Board of Directors.

6. The applicant should be advised that pursuant to IID process, the standard time frame for the implementation of a new substation (engineering, equipment procurement and construction) requires a minimum of 24 months. As a result, the applicant should adjust the project's in-service dates accordingly. The procurement of the new substation banks will commence upon receipt of the customer project application for the substation bank acquisition including payment for the full cost of the required equipment.

7. Line and feeder extensions to serve the project will be made in accordance with IID Regulations:

No. 2 ( http://www.iid.com/horne/showdocument?id=2540) , No. 13 ( http://www.iid.com/home/showdocument?id=2553) , No. 15 ( http://www.iid.com/home/showdocument?id=2555)

8. For additional information regarding electrical service for the project, the applicant should be advised to contact the IID Energy - La Quinta Division Customer Operations, 81-600 Avenue 58 La Quinta, CA 92253, at (760) 398-5841 and speak with the project development planner assigned to the area.

9. It is important to note that IID's policy is to extend its electrical facilities only to those project that have obtained the approval of a city or county planning commission and such other governmental authority or decision -making body having jurisdiction over said developments.

10. The applicant will be required to provide rights of ways and easements for any proposed power line extensions and/or any other infrastructure needed to serve the project as well as the necessary access to allow for continued operation and maintenance of any IID facilities located on adjoining properties.

11. Public utility easements over all private public roads and additional ten (10) feet in width on both side of the private and public roads shall be dedicated to IID for the construction, operation, and maintenance of its electrical infrastructure.

12. Any construction or operation on IID property or within its existing and proposed right of way or easements including but not limited to: surface improvements such as proposed new streets, driveways, parking lots, landscape; and all water, sewer, storm water, or any other above ground or underground utilities; will require an encroachment permit, or encroachment agreement (depending on the circumstances). A copy of the IID encroachment permit application and instructions for its completion are available at https://www.iid.com/about-iid/department-directory/real-estate . The IID Real Estate Section should be contacted at (760) 339-9239 for additional information regarding encroachment permits or agreements.

13. Any new, relocated, modified or reconstructed IID facilities required for and by the project (which can include but is not limited to electrical utility substations, electrical transmission and/or distribution lines, ancillary facilities associated with the conveyance of energy service; the acquisition and dedication of real property, rights of way and/or easements for the siting and construction of electrical utility substations, electrical transmission and/or distribution lines and ancillary facilities associated with the conveyance of energy service, etc.) need to be included as part of the project's California Environmental Quality Act (CEQA) and/or National Environmental Policy Act (NEPA documentation, environmental impact analysis and mitigation. Failure to do so will result in postponement of any construction and/or modification of IID facilities until such time as the environmental documentation is amended and environmental impacts are fully mitigated. Any mitigation necessary as a result of the construction, relocation and/or upgrade of IID facilities is the responsibility of the project proponent.

14. Dividing a project into two or more pieces and evaluating each piece in a separate environmental document (Piecemealing or Segmenting), rather than evaluating the whole of the project in one environmental document, is explicitly forbidden by CEQA, because dividing a project into a number of pieces would allow a Lead Agency to minimize the apparent environmental impacts of a project by evaluating individual pieces separately, each of which may have a less -than -significant impact on the environment, but which together may result in a significant impact. Segmenting a project may also hinder developing comprehensive mitigation strategies. In general, if an activity or facility is necessary for the operation of a project, or necessary to achieve the project objectives, or a reasonably foreseeable consequence of approving the project, then it should be considered an integral project component that should be analyzed within the environmental analysis. The project description should include all project components, including those that will have to be approved by responsible agencies. The State CEQA Guidelines define a project under CEQA as "the whole of the action" that may result either directly or indirectly in physical changes to the environment. This broad definition is intended to provide the maximum protection of the environment. CEQA case law has established general principles on project segmentation for different project types. For a project requiring construction of offsite infrastructure, the offsite infrastructure must be included in the project description. San Joaquin Raptor/Wildlife Rescue Center v. County of Stanislaus (1994) 27 Cal.App. 4th 713.

15. It is important to bear in mind that to address the project impacts to the electrical utility (i.e., the IID electrical grid), considered under the environmental factor "Utilities and Services" of the Environmental Checklist/Intial Study, to determine if the project would require or result in the relocation or construction of new or expanded electric power facilities, the construction or relocation of which could cause significant environmental effects; a circuit study/distribution impact study, facility study, and/or system impact study must be performed.

16. Applicant should be advised that landscaping can be dangerous if items are planted too close to IID's electrical equipment. In the event of an outage, or equipment failure, it is vital that IID personnel have immediate and safe access to its equipment to make the needed repairs. For public safety, and that of the electrical workers, it is important to adhere to standards that limit landscaping around electrical facilities. IID landscaping guidelines are available at https://www.iid.com/energy/veqetation-manaqement .

AHC Skilled Nursing Facility Project (PROJECT)
Mitigated Negative Declaration (MND)
SCH# 2024040501
Dear Ben Torres:

GAVIN NEWSOM, Governor
CHARLTON H. BONHAM, Director
The California Department of Fish and Wildlife (CDFW) received a Notice of Intent to Adopt a Mitigated Negative Declaration (MND) from the City of Rancho Mirage (City) for the Project pursuant to the California Environmental Quality Act (CEQA) and CEQA guidelines.'
Thank you for the opportunity to provide comments and recommendations regarding those activities involved in the Project that may affect California fish and wildlife.

Likewise, we appreciate the opportunity to provide comments regarding those aspects of the Project that CDFW, by law, may be required to carry out or approve through the exercise of its own regulatory authority under the Fish and Game Code.

CDFW ROLE
CDFW is California's Trustee Agency for fish and wildlife resources and holds those resources in trust by statute for all the people of the State. (Fish & G. Code, §§ 711.7, subd. (a) & 1802; Pub. Resources Code, § 21070; CEQA Guidelines § 15386, subd. (a).) CDFW, in its trustee capacity, has jurisdiction over the conservation, protection, and management of fish, wildlife, native plants, and habitat necessary for biologically sustainable populations of those species. (Id., § 1802.) Similarly, for purposes of CEQA, CDFW is charged by law to provide, as available, biological expertise during 10EQA is codified in the California Public Resources Code in section 21000 et seq. The "CEQA Guidelines" are found in Title 14 of the California Code of Regulations, commencing with section 15000.

public agency environmental review efforts, focusing specifically on Projects and related activities that have the potential to adversely affect fish and wildlife resources.

CDFW is also submitting comments as a Responsible Agency under CEQA. (Pub.

Resources Code, § 21069; CEQA Guidelines, § 15381.) CDFW expects that it may need to exercise regulatory authority as provided by the Fish and Game Code. As proposed, for example, the Project may be subject to CDFW's lake and streambed alteration regulatory authority. (Fish & G. Code, § 1600 et seq.) Likewise, to the extent implementation of the Project as proposed may result in "take" as defined by State law of any species protected under the California Endangered Species Act (CESA) (Fish & G. Code, § 2050 et seq.), the Project proponent may seek related take authorization as provided by the Fish and Game Code.

PROJECT DESCRIPTION SUMMARY
Proponent: Prest Vuksic Greenwood Architects
Objective: The proposed Project is the construction of a one-story, 42,526 -square -foot skilled nursing facility. The second phase of development would result in a medical office building, between 5,000 and 10,000 square feet, on the southern portion of the site, adjacent to Gerald Ford Drive. The second medical office building is not currently proposed and will be designed and entitled following the skilled nursing facility. At buildout, the proposed skilled nursing facility and future medical office building would provide a total of 122 parking stalls, including 10 ADA spaces, 4 EV charging stalls, and 54 covered carport spaces. Landscaped area (12,432 square feet) will be provided on - site, featuring drought -tolerant plant species and a water -efficient drip irrigation system.

A four -foot wall will line the site along its northern, southern, and western boundaries.

The Project will be set back from Gerald Ford Drive and Bob Hope Drive by a minimum of 25 feet.

Location: The proposed Project is an approximately 5.75 -acre site located at the northeast corner from the intersection of Bob Hope Drive and Gerald Ford Drive in the City of Rancho Mirage (Assessor's Parcel Numbers 685-120-003 and 685-120-004).

Timeframe: Construction is expected to begin in 2024 and continue through 2025.

COMMENTS AND RECOMMENDATIONS
CDFW has jurisdiction over the conservation, protection, and management of fish, wildlife, native plants, and habitat necessary for biologically sustainable populations of those species (i.e., biological resources). CDFW offers the comments and recommendations below to assist the City in adequately identifying and/or mitigating the Project's significant, or potentially significant, direct and indirect impacts on fish and wildlife (biological) resources. The MND has not adequately identified and disclosed the 11-1300

Ben Torres, Planning Manager
City of Rancho Mirage
May 13, 2024

Project's impacts (i.e., direct, indirect, and cumulative) on biological resources and whether those impacts are reduced to less than significant.

CDFW's comments and recommendations on the MND are explained in greater detail below and summarized here. CDFW is concerned that the MND does not adequately identify or mitigate the Project's significant, or potentially significant, impacts to biological resources. CDFW also concludes that the MND lacks sufficient information to facilitate a meaningful review by CDFW, including a complete and accurate assessment of biological resources on the Project site. CDFW requests that additional information and analyses be added to a revised MND, along with avoidance, minimization, and mitigation measures that avoid or reduce impacts to less than significant.

Existing Environmental Setting
Compliance with CEQA is predicated on a complete and accurate description of the environmental setting that may be affected by the proposed Project. CDFW is concerned that the assessment of the existing environmental setting has not been adequately analyzed in the MND. CDFW is concerned that without a complete and accurate description of the existing environmental setting, the MND may provide an incomplete analysis of Project -related environmental impacts.

The MND lacks a complete assessment of biological resources within the Project site and surrounding area specifically as it relates to special status plant species. A complete and accurate assessment of the environmental setting and Project -related impacts to special status plant species is needed to both identify appropriate avoidance, minimization, and mitigation measures and demonstrate that these measures reduce Project impacts to less than significant.

Mitigation Measures
CEQA requires that an MND include mitigation measures to avoid or reduce significant impacts. CDFW is concerned that the mitigation measures proposed in the MND are not adequate to avoid or reduce impacts to biological resources to below a level of significance. To support the City in ensuring that Project impacts to biological resources are reduced to less than significant, CDFW recommends adding mitigation measures for special -status plants and the Coachella Valley Multiple Species Habitat Conservation Plan (CVMSHCP), as well as revising the mitigation measures for nesting birds and burrowing owl.
1) Assessment of biological resources

CVMSHCP have the potential to occur on the Project site: Chaparral sand -verbena [(Abronia villosa var. aurita)], Borrego milk -vetch [(Astragalus lentiginosus var. 11-1301

Ben Torres, Planning Manager
City of Rancho Mirage

borreganus)], pointed dodder [(Cuscuta californica)], glandular ditaxis [(Ditaxis claryana)], California ditaxis [(Ditaxis serrata var. californica)], Abram's spurge [(Euphorbia abramsiana)], Arizona spurge [(Euphorbia arizonica)], flat -seeded spurge [(Euphorbia platysperma)], ribbed cryptantha [(Johnstonella costata)], and slender cottonheads [(Nemacaulis denudata)]. None of these species were detected on -site during the field assessment, however the assessment was conducted outside of the blooming period." Page 7 of the Project's Biological Resources Assessment dated October 4, 2023 (Biological Assessment), indicates that the field assessment was conducted over a 45 -minute period "between the hours of 1215 and 1300 on 23 July 2023." Section 15125(c) of the CEQA Guidelines states that knowledge of the regional setting of a Project is critical to the assessment of environmental impacts, that special emphasis should be placed on environmental resources that are rare or unique to the region, and that significant environmental impacts of the proposed Project are adequately investigated and discussed. Because the field assessment was conducted outside of the estimated bloom periods for Borrego milk -vetch, glandular ditaxis, Abrams' spurge, Arizona spurge, ribbed cryptantha, and slender cottonheads, it is uncertain if any individuals or significant populations of these species exist within the

5.75 -acre Project site. Surveys implemented using recommended protocols and conducted during the appropriate time(s) of the year is an important step in adequately disclosing potential impacts to special -status native plants and sensitive natural communities. CDFW's Protocols for Surveying and Evaluating Impacts to Special Status Native Plant Populations and Sensitive Natural Communities2 provides the following guidance on timing and number of visits: "Conduct botanical field surveys in the field at the times of year when plants will be both evident and identifiable. Usually this is during flowering or fruiting. Space botanical field survey visits throughout the growing season to accurately determine what plants exist in the project area. This usually involves multiple visits to the project area (e.g., in early, mid, and late -season) to capture the floristic diversity at a level necessary to determine if special status plants are present.3 The timing and number of visits necessary to determine if special status plants are present is determined by geographic location, the natural communities present, and the weather patterns of the year(s) in which botanical field surveys are conducted." Importantly, the findings of appropriate botanical field surveys for special -status native plants and sensitive natural communities are important in informing appropriate 2 Protocols for Surveying and Evaluating Impacts to Special Status Native Plant Populations and Sensitive Natural Communities, California Department of Fish and Wildlife, March 20, 2018.

avoidance, minimization, and mitigation measures and supporting the City in demonstrating that Project impacts are reduced to less than significant.

CDFW recommends that the City include in a revised MND the results of a thorough floristic -based assessment of special -status plants and natural communities performed by a qualified biologist and following CDFW's Protocols for Surveying and Evaluating Impacts to Special -Status Native Plant Populations and Sensitive Natural Communities (CDFW 2018 or most recent version). Based on findings from a recent floristic -based assessment, CDFW recommends that the MND is revised to include an analysis of direct, indirect, and cumulative impacts to biological resources and identification of appropriate avoidance, minimization, and mitigation measures.

CDFW also recommends that City add the following mitigation measure in bold to a revised MND:

Mitigation Measure B10 -[A]: Special -Status Plants
Prior to Project construction activities, a thorough, recent, floristic -based assessment of special status plants and natural communities, following CDFW's Protocols for Surveying and Evaluating Impacts to Special Status Native Plant Populations and Sensitive Natural Communities (see
https://wildlife.ca.qov/Conservation/Plants) shall be performed by a qualified biologist. Should any species of native plants designated as rare, threatened, or endangered by state law (excluding CVMSHCP Covered Species) be present in the Project area, on -site or off -site habitat restoration (whichever is applicable) and/or enhancement and preservation should be evaluated and discussed in detail. Where habitat preservation is not available on -site, off -site land acquisition, management, and preservation should be evaluated.

Pursuant to the CEQA Guidelines, section 15097(f), CDFW has prepared a draft mitigation monitoring and reporting program (MMRP) for revised MM BIO-2 and MM BIO-3 as well as CDFW-recommended MM B10 -[A] and MM BIO-[B]. 2) Nesting Birds
It is the Project proponent's responsibility to comply with all applicable laws related to nesting birds and birds of prey. Fish and Game Code sections 3503, 3503.5, and 3513 afford protective measures as follows: section 3503 states that it is unlawful to take, possess, or needlessly destroy the nest or eggs of any bird, except as otherwise provided by Fish and Game Code or any regulation made pursuant thereto. Fish and Game Code section 3503.5 makes it unlawful to take, possess, or destroy any birds in the orders Falconiformes or Strigiformes (birds -of -prey) or to take, possess, or destroy the nest or eggs of any such bird except as otherwise provided by Fish and Game Code or any regulation adopted pursuant thereto. Fish and Game Code section 3513 makes it 11-1303

unlawful to take or possess any migratory nongame bird except as provided by rules and regulations adopted by the Secretary of the Interior under provisions of the Migratory Bird Treaty Act of 1918, as amended (16 U.S.C. § 703 et seq.).

birds; therefore, a pre -construction survey will be required to avoid impacts to nesting birds covered by the MBTA and to burrowing owls." The Project site contains sparse cover of shrubs, predominantly creosote (Larrea tridentata), which can support nesting birds. Mitigation Measure BIO-3, in the MND, indicates that if "Project -related disturbance (i.e., grading, vegetation removal, operation of heavy equipment, construction, etc.) cannot be avoided during the nesting season (February 1 to August 31), then a nesting bird clearance survey must be conducted by a qualified ornithologist or biologist immediately prior to scheduled on -site disturbance." CDFW considers Mitigation Measure BIO-3 to be insufficient in scope and timing to reduce impacts to nesting birds to a level less than significant. CDFW is concerned about impacts to nesting birds including loss of nesting/foraging habitat and potential take from ground - disturbing activities and construction. Conducting work outside the peak nesting season is an important avoidance and minimization measure. CDFW also recommends the completion of nesting bird surveys regardless of the time of year to ensure that impacts to nesting birds are avoided. The timing of the nesting season varies greatly depending on several factors, such as bird species, weather conditions in any given year, and long- term climate changes (e.g., drought, warming, etc.). In response to warming, birds have been reported to breed earlier, thereby reducing temperatures that nests are exposed to during breeding and tracking shifts in availability of resources (Socolar et al., 20174).

CDFW staff have observed that climate change conditions may result in nesting bird season occurring earlier and later in the year than historical nesting season dates.

CDFW recommends that disturbance of occupied nests of migratory birds and raptors within the Project site and surrounding area be avoided any time birds are nesting on - site. CDFW therefore recommends the completion of nesting bird surveys regardless of the time of year to ensure compliance with all applicable laws pertaining to nesting and migratory birds.

CDFW recommends that the City revise Mitigation Measure BIO-3 with the following additions in bold and removals in strikethrough:

Mitigation Measure BIO-3: Nesting Birds
To the extent feasible, Project -related disturbance (i.e., grading, vegetation removal, operation of heavy equipment, construction, etc.) will be scheduled outside of the peak bird nesting season, which takes place from approximately 4 Socolar JB, Epanchin PN, Beissinger SR and Tingley MW (2017). Phenological shifts conserve thermal niches.

Proceedings of the National Academy of Sciences 114(49): 12976-12981. 11-1304

February 1 through September 15. Regardless of the time of year, nesting bird surveys shall be performed by a qualified avian biologist no more than 3 days prior to vegetation removal or ground -disturbing activities. Pre -construction surveys shall focus on both direct and indirect evidence of nesting, including nest locations and nesting behavior. The qualified avian biologist will make every effort to avoid potential nest predation as a result of survey and monitoring efforts. If active nests are found during the pre -construction nesting bird surveys, a qualified biologist shall establish an appropriate nest buffer to be marked on the ground. Nest buffers are species specific and shall be at least 300 feet for passerines and 500 feet for raptors. A smaller or larger buffer may be determined by the qualified biologist familiar with the nesting phenology of the nesting species and based on nest and buffer monitoring results. Construction activities may not occur inside the established buffers, which shall remain on site until a qualified biologist determines the young have fledged or the nest is no longer active. Active nests and adequacy of the established buffer distance shall be monitored daily by the qualified biologist until the qualified biologist has determined the young have fledged or the Project has been completed. The qualified biologist has the authority to stop work if nesting pairs exhibit signs of disturbance. If Project -related disturbance (i.e., grading, vegetation removal, operation of heavy equipment, construction, etc.) cannot be avoided during the nesting season nesting birds are found, no work buffer zones of about 100 to 300 feet for unlisted monitored until young have fledged.
3) Burrowing Owl
Burrowing owl is a California Species of Special Concern. Take of individual burrowing owls and their nests and eggs is defined by Fish and Game Code section 86, and prohibited by sections 3503, 3503.5, and 3513. Fish and Game Code section 3513 makes it unlawful to take or possess any migratory nongame bird except as provided by rules and regulations adopted by the Secretary of the Interior under provisions of the Migratory Bird Treaty Act of 1918, as amended (16 U.S.C. § 703 et seq.). Take is defined in Fish and Game Code section 86 as "hunt, pursue, catch, capture or kill, or attempt to hunt, pursue, catch, capture or kill."
Permittees of the CVMSHCP must ensure that Covered Activities within their jurisdictions —both inside and outside Conservation Areas —do not result in the take of the burrowing owl individuals, nests, or eggs. Per Section 3.5.6 of the California Department of Fish and Wildlife (CDFW) Natural Community Conservation Plan (NCCP) Permit #2835-2008-001-06 for the CVMSHCP, "take outside of Conservation Areas will be consistent with sections 3503 and 3503.5 of the Fish and Game Code." Adding further clarification, Section 3.5.6 of CDFW's NCCP Permit indicates that "following all 11-1305

Ben Torres, Planning Manager
City of Rancho Mirage
May 13, 2024

laws applicable to migratory birds (discussed below), the pairs or individuals will not be Taken, just the land around and including the burrows", and "the HCP/NCCP does not authorize Take of nests and eggs as prohibited by Fish and Game Code sections 3503 and 3503.5 and therefore avoidance measures will have to be undertaken for all projects which have breeding burrowing owls present." An activity that results in the take of burrowing owl individuals, nests, or eggs would be unlawful and would not be a Covered Activity under the CVMSHCP. Per Section 13.2 of the CVMSHCP Implementing Agreement, County and Cities obligations include, but are not limited to, taking "all necessary and appropriate actions, following applicable land use permit enforcement procedures and practices, to enforce the terms of project approvals for public and private projects, including compliance with the MSHCP, the Permits and this Agreement." The City has an obligation under the CVMSHCP to ensure the Project does not result in the take of burrowing owl individuals, nests, and eggs.

owls, and/or sign thereof, were not observed or detected on -site during the assessment, potentially suitable habitat (i.e., sparse Sonoran creosote bush scrub) remains present (Appendix D). No burrows of sufficient size were observed on -site at the time of the assessment (only small invertebrate, lizard and/or rodent burrows were observed). The site is relatively small (6 acres) and surrounded on all sides by existing and on -going development, which has isolated the biological resources on -site from any other available undeveloped open space, which further reduces the overall likelihood of burrowing owl occurring on -site." In California, preferred habitat for burrowing owl is generally typified by short, sparse vegetation with few shrubs,5 and that burrowing owls may occur in ruderal grassy fields, vacant lots, and pastures if the vegetation structure is suitable and there are useable burrows and foraging habitat proximity.6 Based on review of aerial imagery, the Project site contains sparse vegetation cover and provides suitable habitat for burrowing owl. The Project site is located near disturbed open areas to the south and an open space area located approximately 220 meters to the southwest that may support burrowing and foraging habitat for burrowing owls; burrowing owls have been found to concentrate foraging efforts within 600 meters of a nest burrow in southern California'. In addition, burrowing owls frequently move into 5 Haug, E. A., B. A. Mil!sap, and M. S. Martell. 1993. Burrowing owl (Speotyto cunicularia), in A. Poole and F. Gill, editors, The Birds of North America, The Academy of Natural Sciences, Philadelphia, Pennsylvania, and The American Ornithologists' Union, Washington, D.C., USA.

disturbed areas prior to and during construction activities since they are adapted to highly modified habitats8,9. Suitable habitat for burrowing owl exists within the Project site and within nearby disturbed areas to the south and open space areas to the southwest, and burrowing owls have the potential to move onto the site prior to and during construction activities.

Although the MND includes Mitigation Measure BIO-2 for burrowing owl, CDFW considers the measure to be insufficient in scope and timing to reduce impacts to a level less than significant. CDFW recommends that the City revise Mitigation Measure BIO-2 with the following additions in bold and removals in strikethrough:

Mitigation Measure BIO-2: Burrowing Owl Surveys
Suitable burrowing owl habitat has been confirmed on the site; therefore, focused burrowing owl surveys shall be conducted by a qualified biologist according to the Staff Report on Burrowing Owl Mitigation prior to vegetation removal or ground -disturbing activities. If burrowing owls are detected during the focused surveys, the qualified biologist and Project proponent shall begin coordination with CDFW and USFWS immediately, and shall prepare a Burrowing Owl Plan that shall be submitted to CDFW for review and approval prior to commencing Project activities. The Burrowing Owl Plan shall describe proposed avoidance, minimization, mitigation, and monitoring actions. The Burrowing Owl Plan shall include the number and location of occupied burrow sites, acres of burrowing owl habitat that will be impacted, details of site monitoring, and details on proposed buffers and other avoidance measures if avoidance is proposed. If impacts to occupied burrowing owl habitat or burrow cannot be avoided, the Burrowing Owl Plan shall also describe minimization and relocation actions that will be implemented. Proposed implementation of burrow exclusion and closure should only be considered as a last resort, after all other options have been evaluated as exclusion is not in itself an avoidance, minimization, or mitigation method and has the possibility to result in take. If impacts to occupied burrows cannot be avoided, information shall be provided regarding adjacent or nearby suitable habitat available to owls along with proposed relocation actions. The Project proponent shall implement the Burrowing Owl Plan following CDFW and USFWS review and approval.

Preconstruction burrowing owl surveys shall be conducted no less than 14 days prior to the start of Project -related activities and within 24 hours prior to ground disturbance, in accordance with the Staff Report on Burrowing Owl Mitigation (2012 or most recent version). Preconstruction surveys should be performed by a qualified biologist following the recommendations and guidelines provided in the Staff Report on Burrowing Owl Mitigation. If the preconstruction surveys confirm occupied burrowing owl habitat, Project activities shall be immediately halted. The qualified biologist shall coordinate with CDFW and prepare a Burrowing Owl Plan that shall be submitted to CDFW and USFWS for review and approval prior to commencing Project activities.

4) Coachella Valley Multiple Species Habitat Conservation Plan The Project is located within the CVMSHCP Plan Boundary and outside of a Conservation Area. Page 32 of the MND indicates that the "Project site is within the CVMSHCP planning area, and thus is required to pay the land development/mitigation fee". Section 5.2.1.1 of the CVMSHCP indicates that "Local jurisdictions will impose a mitigation fee on new Development within the Plan Area that impacts vacant land containing Habitat for the Covered Species or any of the conserved natural communities in the Plan through adoption, or amendment of an existing fee ordinance." The Project site contains suitable habitat for burrowing owl and other CVMSHCP Covered Species as further discussed on page 30 of the MND; therefore, the City is required to impose a local development fee for the Project. To document this obligation, CDFW recommends the City add the following mitigation measure to a revised MND:

Mitigation Measure B10 -[B]: CVMSHCP Compliance
Prior to construction and issuance of any grading permit, the City of Rancho Mirage shall ensure compliance with the Coachella Valley Multiple Species Habitat Conservation Plan (CVMSHCP) and its associated Implementing Agreement and shall ensure the collection of payment of the CVMSHCP Local Development Mitigation Fee and transfer of revenues to the Coachella Valley Conservation Commission.
5) Landscaping

tolerant plant species and an efficient drip irrigation system." No other details are provided in the MND on the Project's proposed landscaping plans. CDFW recommends 11-1308

Ben Torres, Planning Manager
City of Rancho Mirage
May 13, 2024

incorporation of water -wise concepts in any Project landscape design plans. In particular, CDFW recommends xeriscaping with locally native California species and installing water -efficient and targeted irrigation systems (such as drip irrigation). Native plants support butterflies, birds, reptiles, amphibians, small mammals, bees, and other pollinators that evolved with those plants. More information on native plants suitable for the Project location and nearby nurseries is available at Calscape: https://calscape.org/ .

Local water agencies/cities and resource conservation cities in your area may be able to provide information on plant nurseries that carry locally native species, and some facilities display drought -tolerant locally native species demonstration gardens.

Information on drought -tolerant landscaping and water -efficient irrigation systems is available on California's Save our Water website: https://saveourwater.com/ . CDFW also recommends that the MND include recommendations regarding landscaping from Section 4.0 of the CVMSHCP "Table 4-112: Coachella Valley Native Plants Recommended for Landscaping" (pp. 4-180 to 4-182; https://cvmshcp.org/plan- documents/).

ENVIRONMENTAL DATA
CEQA requires that information developed in environmental impact reports and negative declarations be incorporated into a database which may be used to make subsequent or supplemental environmental determinations. (Pub. Resources Code, § 21003, subd. (e).) Accordingly, please report any special status species and natural communities detected during Project surveys to the California Natural Diversity Database (CNDDB). The CNNDB field survey form can be filled out and submitted online at the following link: https://wildlife.ca.gov/Data/CNDDB/Submitting-Data . The types of information reported to CNDDB can be found at the following link:
https://www.wildlife.ca.qov/Data/CNDDB/Plants-and-Animals .

ENVIRONMENTAL DOCUMENT FILING FEES
The Project, as proposed, would have an impact on fish and/or wildlife, and assessment of environmental document filing fees is necessary. Fees are payable upon filing of the Notice of Determination by the Lead Agency and serve to help defray the cost of environmental review by CDFW. Payment of the environmental document filing fee is required in order for the underlying Project approval to be operative, vested, and final. (Cal. Code Regs, tit. 14, § 753.5; Fish & G. Code, § 711.4; Pub. Resources Code, § 21089.)

CONCLUSION
CDFW appreciates the opportunity to comment on the MND to assist the City in identifying and mitigating Project impacts to biological resources. CDFW concludes that the MND does not adequately identify or mitigate the Project's significant, or potentially significant, impacts to biological resources. CDFW also concludes that the MND lacks 11-1309

Ben Torres, Planning Manager
City of Rancho Mirage
May 13, 2024

sufficient information for a meaningful review of impacts to biological resources, including an assessment of impacts associated with special status plants. The CEQA Guidelines indicate that recirculation is required when a new significant effect is identified and additional mitigation measures are necessary (§ 15073.5). CDFW recommends that the MND is revised to include a complete assessment of biological resources (special status plants), and that the MND is recirculated for public comment.

CDFW also recommends that revised and additional mitigation measures and analysis as described in this letter be added to a revised MND.

CDFW personnel are available for consultation regarding biological resources and strategies to avoid and minimize impacts. Questions regarding this letter or further coordination should be directed to Jacob Skaggs, Senior Environmental Scientist Specialist, at jacob.skaggs©wildlife.ca.gov.

PROJECT SUMMARY
Consideration to construct a one story 42,526 square foot (46 beds) skilled nursing facility. The facility will provide short term, inpatient, post -acute, and medical care as needed to help patients recover more effectively after a hospital visit. Licensed nursing and other medical professionals would provide 24 -hour care. In addition to the various site improvements, a building pad for a future 5,000 to 10,000 square foot medical office building is proposed. A Tentative Parcel Map is also included in the entitlement package to subdivide the property into two parcels.

The following applications comprise the entitlement package: Environmental Assessment (EA), Tentative Parcel Map (TPM), Conditional Use Permit (CUP), and Preliminary Development Plan (PDP).

BACKGROUND AND EXISTING CONDITIONS
The project site is in the western half of Section 30, which was annexed to the City in 1994 as part of a larger annexation that extended north to 1-10 and east of Bob Hope Drive. The City Council granted office zoning to this project site in addition to most parcels fronting Bob Hope Drive as part of the annexation process. On June 16, 2004 a Parcel Merger was recorded on the project site.

The project applicant held a community meeting on January 24, 2024, and invited the surrounding property owners to provide preliminary input on the project. Three out of the four property owners to the east of the project site attended. The project applicant made modifications to the plans based on the comments received.

EA23-0009, TPM23-0003, CUP23-0004, & PDP23-0004 Page 3 of 30 JUSTIFICATION OR INFORMATION CONTINUED:

The subject site is currently vacant and undeveloped. The property is relatively flat, with sparse desert scrub vegetation. Meandering sidewalks line the southern and western boundaries of the site, along the frontages with Gerald Ford Drive and Bob Hope Drive. An existing block wall separates the Project site from the existing residential development to the east. The lands on all sides of the site are developed with a mix of medical office, residential and commercial uses.

ENVIRONMENTAL ASSESSMENT CASE NO. EA23-0009
An environmental assessment application was submitted for the proposed project and the determination was made that the project required an Initial Study. An Initial Study has been prepared resulting in the recommendation to adopt a Mitigated Negative Declaration (MND).

Mitigation measures were recommended for Biological Resources, Cultural & Tribal Cultural Resources, and Geology and Soils. A Notice of Determination will be filed with the Riverside County Clerk once a final determination has been made by the City Council. The complete Initial Study, along with the Mitigation Monitoring and Reporting Program, is included in Attachment 3 — Draft Mitigated Negative Declaration.

A Notice of Intent to Adopt a Mitigated Negative Declaration was published in the Desert Sun on April 12, 2024, and distributed to interested parties on April 11, 2024. The Initial Study/ Mitigated Negative Declaration was circulated for a 30 -day public review period starting on April 12, 2024 to May 11, 2024, and the City received four comment letters. The letters received were from Colleen Hamilton (property owner of 11 Cassis Circle) immediately adjacent to the proposed project site, the California Department of Fish and Wildlife (CDFW), Imperial Irrigation District, and the Agua Caliente Tribe.

While the City is not required to respond to comments, Sections 21091(d)(1) and 21092.5 of the Public Resources Code (PRC) and Section 150874 (b) of the California Environmental Quality Act Guidelines require that before project approval a Lead Agency must consider all comments received before making a final determination. With due consideration of the proposed mitigation measures, the City included a response to comments which was included as in the Draft Mitigated Negative Declaration.

AB 52 Tribal Consultation
Public Resource Code 21074 identifies "Tribal Cultural Resources" as "sites, features, places, cultural landscapes, sacred places, and objects with culture value to California Native American Tribe" and that are either included or determined to be eligible for inclusion on the national, state, or local register of historic resources or that are determined by the lead agency, in its discretion, to be significant when taking into consideration the significance of the resource to a California Native American Tribe.

Assembly Bill 52 (AB 52) requires lead agencies to notify their local tribes about development projects. It also mandates lead agencies consult with Tribes if requested and sets the principals for conducting and concluding the required consultation process. Pursuant to AB 52 consultation requirements, the City contacted 16 tribes and representatives provided by the Native American Heritage Commission (NAHC).

Pursuant to AB 52 consultation requirements, the City of Rancho Mirage initiated a 30 -day consultation period from November 17, 2023, to December 17, 2023. During the consultation Planning Commission Staff Report AGENDA ITEM #

The Agua Caliente Band of Cahuilla Indians requested approved Agua Caliente cultural resources monitor during ground disturbing activities in addition to other documentation related to the project. The Morongo Band of Mission Indians suggested that the City consult with local tribes closely associated with the project site. The Agustine Band of Cahuilla Indians requested to be notified of any cultural resources discovered during development of the project site. No other comments were received from other tribes.

Tentative Parcel Map Case No. TPM23-0003
The property has two Assessor's Parcel Numbers due to a Parcel Merger recorded in 2004 but is considered one parcel currently; the applicant is proposing a Tentative Parcel Map to establish two new parcels. The proposed Tentative Parcel Map No. 38844 is intended to subdivide the

5.61 -acre property into two parcels which consist of a 4 acre parcel for the Skilled Nursing Facility project site and a 1.40 acre parcel for the future building pad site. The Office zone does not set a minimum parcel size so both proposed parcels are in compliance with the applicable development standards.

CONDITIONAL USE PERMIT CASE NO. CUP23-0004
The purpose of a Conditional Use Permit is to allow for uses which are so unique that their effect on the surrounding environment cannot be determined before being proposed for a particular location. A Conditional Use Permit is required for the Skilled Nursing Facility due to its unique operations that provide 24 -hour care. As part of the Conditional Use Permit process the Skilled Nursing Facility building will be limited to only Skilled Nursing uses with a maximum capacity of 46 beds. Per Condition of Approval #29 any change in the use and/or operations of the Skilled Nursing Facility building shall be subject to a Conditional Use Permit Modification, as determined by the Planning Division. Changes in use may require additional review by staff and the approving body.

This facility will operate with private patient rooms among other amenities. The facility will provide short term, inpatient, post -acute, medical care as needed to help patients recover and recuperate more effectively after a hospital visit. The primary care platform will be the service of post -acute patients with rehabilitation needs. The facility will specialize in helping patients recover from such events as fractures, joint replacements, strokes, heart attacks and similar events that require additional therapy and support after surgery or other medical procedures.

Physical, occupational and speech therapy, skilled nursing and related services will be provided to help patients continue their recovery process in a monitored, comfortable, and private environment to regain their function and prepare them to return home.. In case of a sudden life - threatening event, the staff will stabilize the person as best as possible until an ambulance arrives and transports the patient to an appropriate hospital. Airborne Infection Isolation Rooms (AIIR) will not be provided in the facility so patients requiring airborne isolation will not be admitted to the facility and any patients that develop the condition after arrival will also be discharged to an appropriate facility. Licensed nursing professionals including RN's, LPN's and CNA's will provide 24 -hour care, which may include wound care, IV therapy, assistance with dressing, bathing, walking and dining. Medications are provided by a licensed pharmacy, dispensed per the physician's order and administered by licensed nurses. Physical, occupational, and speech therapists address patient's rehab based upon physician's orders and assessment of need.

Additionally, a certified dietary manager and trained cooks will provide nutritious meals either in the dining commons or the patient's room. The programs and services are provided under the supervision of a licensed Nursing Home Administrator, Director of Nursing (DON), Rehab Services Manager (RSM) and Registered Dietitian.

PRELIMINARY DEVELOPMENT PLAN CASE NO. PDP23-0004
The Preliminary Development Plan for the project consists of the 42,526 square foot Skilled Nursing Facility building and all site improvements. This includes landscaping and parking for the Future Building Site parcel. No plans for the Future Building Site are part of this Preliminary Development Plan and future entitlements will need to be obtained.

Access and Circulation
The project site will be accessed through two driveways with enhanced stamped concrete. The two driveways are along Gerald Ford Drive and Via Marta, which immediately leads to the Skilled Nursing Facility entrance. Only right in and right -out capabilities will be available on Gerald Ford Drive. In addition, various other internal drive aisles with a minimum width of 24' will provide internal circulation to the various parking areas within the property.

Lot Coverage
The Office zone has a 35% lot coverage maximum, which is defined as the building -ground contact area divided by the total site area. The project site will be subdivided into two parcels, a

4.40 -acre (174,087 sq. ft.) parcel for the Skilled Nursing Facility and a 1.40 acre (61,162 sq. ft.) parcel for the Future Building Site. The Skilled Nursing Facility has a total ground floor enclosed area of 42,526 square feet, which equals to a lot coverage of 24.4%, meeting the 35% maximum.

No building plans have been submitted for the Future Building Site but based on the maximum square footage of 10,000 square feet studied in the project Mitigated Negative Declaration lot coverage will not exceed 16.4%, which again is below the 35% maximum.

Setbacks
The following table summarizes the setbacks proposed for the project. Setbacks are measured from the exterior property lines of the overall project site and the requirements of the Office zone:

The proposed pad heights are based on the existing conditions of the project site and are appropriate for their location.

Various drainage improvements will direct the flow of water away from the buildings and parking areas to three proposed retention basins. Two of the retention basins will be located next to the Skilled Nursing Facility taking advantage of the open space created between two wings of the facility and the other will be at the intersection of Bob Hope Drive and Gerald Ford Drive. A final Hydrology Report is conditioned to be submitted to the Public Works Department and shall be required to meet all City requirements.

Floor/Roof Plan
The Skilled Nursing Facility will consist of 46 beds with bedrooms along the wings of the facility.

At the center of the facility various offices, physical therapy areas, multipurpose areas and dining areas will be located to provide patients with convenient access to services. The nurses' station will also be located at the center of the facility to provide quick and convenient access to all patient areas and bedrooms since the facility will provide 24 -hour care.

The building's roof will have a variety of heights and will contain three mechanical well areas at the central area of the building that will screen rooftop mechanical equipment from view.

Parking
The following table provides a breakdown of the minimum parking required; an analysis of the future Building Site is also included for reference purposes based on the maximum size studied in the project Mitigated Negative Declaration.

Electric Vehicle Charging Stations
Pursuant to Section 17.26.030 of the Rancho Mirage Municipal Code (RMMC), all new construction and projects requiring discretionary action shall provide a defined amount of electric vehicle charging stations. For projects that have between 51-200 parking spaces, two (2) electric vehicle charging spaces are required. The project proposes a minimum of four (4) electric vehicle charging spaces near the entrance to the Skilled Nursing Facility and eastern parking area.

Shaded Parking
Pursuant to Section 17.26.070 of the RMMC, a minimum of 25% of the parking spaces shall be shaded. The new parking area exceeds this requirement with 46% of the spaces having carports.

A total of 54 out of the 121 parking spaces will be covered with carports, which will be painted in tan and silver to complement the building designs. The carports will have a maximum height of 9' — 8". The carports are primarily located on the eastern parking area, with some along the Bob Hope frontage as well. The surface parking areas that do not have carports will also be shaded by various 36 -inch box Fruitless Olive trees and Date Palms with an approximate height of 15 feet.

ADA Parking
Pursuant to Section 17.26.060 of the RMMC, a proposed project of 101-150 parking spaces shall provide a minimum of five (5) handicapped parking spaces. The project meets this requirement with a total of 10 spaces scattered throughout the parking area to provide sufficient ADA parking to the Skilled Nursing Facility and Future Building Site.

Architecture

Building Height
Height Consideration: Although the project is a one-story design, heights above 20 feet are proposed in select areas to create a unique architectural experience. Staff has conducted analysis per Section 17.20.100 of the Rancho Mirage Municipal Code (RMCC), which governs structures over 20' in height. The following is Staff's additional analysis of the proposed building heights:

1. In addition to the minimum required setbacks for one (1) story or twenty (20) foot high buildings, the setback shall be increased a minimum of two (2) feet for each one (1) foot of additional building height above twenty (20) feet; however, the council in exercising their discretion may require significantly greater setbacks; Staff Response: The project consists of one freestanding building that incorporates features that are above 20' in height but meet the additional setback requirements.

The maximum height of the Skilled Nursing Facility will be 33 feet 4 inches, but this maximum height will only be for one tower element over the main entrance. A majority of the facility will have heights ranging from 22'-6" to 27'-2". Building heights along the eastern side of the facility will begin at 19' and slope upwards. The taller portions of the building are centered away from the front and rear side property lines. The additional roof heights are intended to create visual interest to the building with elements used to create and accentuate architectural features while ensuring mechanical equipment screening. A height limit study was included in the Exhibit Booklet (see pg. A104 -A105 of Attachment 9). The study shows roof areas that exceed 20 feet in height and line of sight studies for each building are provided showing how every area of the building along exterior property lines complies with the additional setbacks required per the municipal code.

2. Enhanced buffering to surrounding development, land uses designations, and zoning shall be demonstrated.

Staff Response: The applicant designed the project with the surrounding developments in mind. The Skilled Nursing Facility is placed on the western half of the parcel furthest away from existing residential; the design has provided enhanced setbacks and screening through landscape and building orientation. The building, with its enhanced setbacks, meets the requirements in the Municipal Code.

3. A visual and spatial analysis relating building proportions, massing, height, and setback shall be conducted to preserve and enhance the scenic view shed.

Staff Response: A detailed height limit study, line -of -sight studies and site sections were prepared for the Skilled Nursing Facility building that show it will be in compliance in regard to height and be compatible with the neighborhood.

4. The need and appropriateness of the additional height shall be demonstrated.

Staff Response: The applicant has paid special attention to the placement of the additional height. The additional height is to create an open and welcoming environment for patients of the Skilled Nursing facility and to add additional architectural interest to the massing and scale of the building. In addition, the project is in compliance with the height requirements of the Municipal Code pursuant to Section 17.20.100.

5. Compatibility and harmony with surrounding development, land uses designations, and zoning shall be demonstrated.

Staff Response: The building is designed as a single story, with height increases included within areas of the project that will create minimal impact to the surrounding developments. All heights exceeding 20 feet provide at minimum an additional two feet of setback for every additional foot in height. The sight line analysis provided, setbacks and architectural design of the project conclude that the proposed project is compatible and harmonious with existing one story and two-story developments within the vicinity.

The two story office building immediately north of the project site has heights of up to 37 feet. Other buildings north of the project site on Bob Hope Drive have increased heights as well. Examples include the Weil Institute with heights up to 38' and Rancho Mirage Terrance Assisted Living Facility with roof heights up to 36'. Therefore, based on the increased setbacks and existing conditions along Bob Hope Drive, the project site is compatible with the surrounding developments.

Setbacks of 110' and 220' from the eastern property line are provided for heights of 27' and 33'-4" respectively along the residential portion of the project. The closest wing of the facility will be set back approximately 68' from the adjacent residential property line and at that point the building height measures 14 feet and then begins to slope upwards.

Landscape
Landscaping along the perimeter of the project site along Bob Hope Drive and Gerald Ford Drive consists of various 48 -inch box Desert Museum Palo Verde trees complimented with 36 -inch box Mulga trees. Along Via Marta various 15 -foot -tall Date Palms will line the street frontage. In order to screen the parking areas, a combination of a 4 -foot -tall wall along with a landscape hedge screen wall consisting of Houdini Sage is proposed around the entire property. The project site is designated with a Special Corner Overlay and at the intersection of Bob Hope Drive and Gerald Ford Drive the increase setbacks allow for a variety of interest with varying landscape heights and colors. A mosaic wall and future sculpture area are proposed. The design has not been finalized and will be required as part of the Final Development Plan.

Palm Springs Gold 3/8" crushed rock will be the primary ground cover provided within the planter areas. Within the parking areas various landscape fingers will provide a visual break in the number of continuous parking spaces. Shrubs proposed within the project site consist of Red Bird of Paradise, White Lantana, and Rio Bravo Sage to name a few. Overall, the project is richly planted with a wide variety of landscaping to provide enhanced visual interest.

Two decorative trash enclosures are also located on the site with one on the eastern end of the Skilled Nursing Facility site and set back approximately 90 feet from the east property line. A Planning Commission Staff Report AGENDA ITEM #

Condition of Approval (COA # 37) has been added that the relocation of the Skilled Nursing Facility trash enclosure to the western half of the project site shall be studied as part of the Final Development Plan process, subject to Planning Division approval. The other trash enclosure is already located on the western half of the site to serve the Future Building Site. In addition, a generator enclosure will be located on the western half of the site next to richly planted landscaped areas.

Project Lighting
The project's photometric plan details the type of lighting that is proposed as well as the proposed light readings on the property. A variety of LED light fixtures are proposed to illuminate the parking areas and landscape. Freestanding light fixtures are proposed as the primary light source within the parking areas and will have a maximum height of 15 feet. Carport lighting under the canopy is also proposed to illuminate the center of the parking area. The project's photometric plan will have a zero -foot candlelight reading at the exterior property lines of the project site. Due to the project close proximity to existing residences the free-standing light fixtures are limited to a maximum height of 15 feet and are conditioned to be fitted with full cut- off glare shields, and shall be Dark Sky compliant (See COA #32). In addition, the project's final photometrical plan will require a zero foot candlelight reading (see COA #28) at all property lines, including those to the east (Escala Residences).

Final Development Plan (FDP)
Prior to the issuance of any building permits, the applicant shall submit a Final Development Plan and pay the requisite fees. The FDP shall include detailed written responses to each of the project's conditions of approval along with final sets of construction, grading, lighting and landscaping plans.

Any revisions that are in substantial compliance with the original project, and do not trigger the need for additional environmental analysis, can likely be reviewed at the staff level through either the FDP process or Minor Modification process. If, however, there are wholesale changes to the project during the FDP review, the applicant shall be required to submit additional applications to modify the entitlement as necessary.

ARCHITECTURAL REVIEW WORKING GROUP (ARWG)
On March 26, 2024, the proposed project was presented to the Architectural Review Working Group (ARWG). Staff provided an overview of the proposed project and opened the discussion. The applicant's team discussed their design approach to the project further elaborate on key elements of the project. The ARWG raised questions regarding the front door vestibule design, wind control, material selection, and landscaping. The questions related to wind control and vestibule design will be addressed upon the submittal of the Final Development Plan (see Conditions of Approval).

Public Comments
Steven Friscia, resident of Rancho Mirage, commented that the project looked very nice and he was pleased with the setbacks. He expressed concern about the future office building site location, indicating he preferred to see the skilled nursing facility at that location.

Nasim Tourkaman, resident of Rancho Mirage, was in attendance on behalf of her parents to oppose the proposed project. She commented that they would prefer that site be developed for office uses with typical office operating hours. She expressed concern with 24 -hour operation, noise, building heights, lighting, view impacts, and traffic. She also summarized a prior community meeting organized by the project developers where several concerns regarding the trash enclosure and generator were raised, some of which were addressed. She respectfully requested that the trash enclosure be relocated and building height lowered.

Commissioner Comments
Commissioner Chanter asked the applicant's project manager to address resident concerns.

Alan Warren, project manager for the development team, thanked staff for being extremely helpful as the development team had carefully spent the last five years analyzing projects and their impact on the communities that they develop in. He summarized the proposed project's design, noting that the facilities were intended to help people heal and go back to their everyday lives. Mr. Warren added that a community meeting was held early in the process, where a number of concerns were heard, such as lighting, trees, trash enclosures, and building heights.

He added that they addressed the concerns and made a number of changes to what was originally proposed. He noted that the development team increased the set -back, to move the buildings away from the residences that were more closely impacted. He added that they also made adjustments to the trees that were initially proposed and rethought the lighting for the entire development.

DRAFT 5/30/2024 Planning Commission Meeting Minutes Page 2 of 7 11-1372

John Greenwood, PVG Architects, highlighted two additional questions that were raised by residents regarding the future building site, noting that it would meet all requirements of the Special Corner Overlay, which included a setback of 122 feet measured at a 45° angle from the curb at the intersection of Bob Hope Drive and Gerald Ford Drive. He elaborated that medical uses would be intended for the future building site, which would be one-story, and most likely in the 5,000 square -foot range. He confirmed that considerations were made to address the generator, which was moved to the Bob Hope side and the trash enclosure was relocated much closer to the building next to the back of house. Mr. Greenwood added that all lighting along the eastern boundary was eliminated and the project met night sky requirements.

Commissioner Chanter asked the development team to clarify the skilled nursing facility's stay duration.

Mr. Warren clarified that the facility would be for short-term rehabilitation, with stays of 21 days or less.

Commissioner Chanter commented that she liked that the development team met with the community and made changes to create an attractive design.

Commissioner Curran made positive comments on the design and spoke in favor of the future office building location. He added that plenty of parking was provided and the height of the building was in line with surrounding projects. He appreciated that the development team worked with the community to try to accommodate changes.

Vice Chair Agostini noted that he felt the public comments had been addressed. He agreed with the other Commissioners in regard to the facility being very appealing.

Commissioner Bryant thanked the development team for the very well -prepared project.

He inquired about the future development and if they had to meet all future conditions of approval.

Mr. Torres confirmed that the developer would have to submit a new entitlement application when they were ready to develop the pad site and go through the entitlement process.

Commissioner Bryant expressed concern about traffic and the right turn lane on Gerald Ford Drive in regard to traffic slowing down to turn right into the development. He inquired about a right turn pocket for the site, setbacks, and landscaping.

Mr. Torres elaborated on the landscaping proposed and confirmed the future building site would have a minimum setback of 25 feet from the property line on the Gerald Ford frontage. He added that the building would be located 51 feet from the curb and would be set back in compliance with the Special Corner Overlay. He also explained the existing dry well and current right turn pocket conditions.

Commissioner Bryant praised the building design and spoke of a need for these facilities.

He inquired about the conditional use permit, facility staffing, and required approvals.

DRAFT 5/30/2024 Planning Commission Meeting Minutes Page 3 of 7 1-1373

Majna Dukic, Development Services Director, answered Commissioner Bryant's questions about the conditional use permit and Mr. Warren answered the staffing and licensing oversight questions.

Vice Chair Agostini asked staff to clarify how the right turn issue brought up by Commissioner Bryant would be addressed.

Mr. Torres commented that the Public Works Department and staff were supportive of the current design; however, staff would work with the applicant to address the concern.

The purpose of this project is to construct a new, one story, 46 bed, 42,526 SF skilled nursing facility. This facility will be state of the art, inclusive of large therapy spaces, courtyards, upscale dining, and flat screen HDTVs in private patient rooms among other high-end amenities. Facility will provide short term, inpatient, post-acute, medical care as needed to help patients recover and recuperate more effectively after a hospital visit.

This facility will increase the availability of skilled nursing services to the greater Rancho Mirage population. The building will be a purpose-built facility designed for today’s modern care and medical management technology. The primary care platform will be the service of post-acute patients with rehabilitation needs.

The facility will specialize in helping patients recover from such events as fractures, joint replacements, strokes, heart attacks and similar events that require additional therapy and support after surgery or other medical procedures. Physical, occupational and speech therapy, skilled nursing and related services will be provided to help patients continue their recovery process in a monitored, comfortable, and private environment to regain their function and prepare them to return home.

Because the facility is limited to nursing physical, occupational, and speech rehabilitation procedures, acute care for events such as heart attacks, strokes, or respiratory ailments will not be provided. In case of a sudden life-threatening event, the staff will stabilize the person as best as possible until an ambulance arrives and transports the patient to an appropriate hospital. Airborne Infection Isolation Rooms (AIIR) will not be provided in the facility so patients requiring airborne isolation will not be admitted to the facility and any patients that develop the condition after arrival will also be discharged to an appropriate facility.

Licensed nursing professionals including RN’s, LPN’s and CNA’s provide 24-hour care, which may include wound care, IV therapy, assistance with dressing, bathing, walking and dining. Medications are provided by a licensed pharmacy, dispensed per the physician’s order and administered by licensed nurses. Physical, occupational, and speech therapists address patient’s rehab based upon physician’s orders and assessment of need.

Each discipline offers a wide variety of programs to help patients attain their maximum potential and restore their functional abilities. Additionally, a certified dietary manager and trained cooks provide nutritious and delicious meals either in the dining commons or the patient’s room. The programs and services are provided under the supervision of a licensed Nursing Home Administrator, Director of Nursing (DON), Rehab Services Manager (RSM) and Registered Dietitian.
