EXECUTIVE SUMMARY

A proposed specific plan for an eventual residential/commercial subdivision within the Agua Caliente Indian Reservation necessitated a biological survey and impact analysis.

Five species covered under the Tribal Habitat Conservation Plan (THCP) of the Agua Caliente Band of Cahuilla Indians were detected onsite and are considered resident: the Coachella Valley milk-vetch, Coachella Valley fringe-toed lizard, flat-tailed horned lizard, western burrowing owl (Mountains and Canyons Conservation Area only) and Palm Springs Ground Squirrel. Three additional covered species (Coachella giant sand-treader cricket, Coachella Valley Jerusalem cricket and Palm Springs pocket mouse) may occur onsite but were not detected.

Most of the land within the project boundaries is considered habitat for the Coachella Valley fringe-toed lizard. Six observations of this species were recorded and the loose, wind-blown sand substrate that covers most of the site is the lizard’s preferred habitat. The flat-tailed horned lizard also favors wind-blown sand flats and one specimen of this species was recorded.

The western burrowing owl was detected within the project boundaries on six occasions including one active burrow. A survey for owls is recommended not more than 30-days prior to future ground disturbance on the site. The Palm Springs ground squirrel was detected only twice in the southwestern quarter of the site but should be expected throughout the project area.

The Coachella Valley milk-vetch has previously been recorded from the site. However, three years of drought, including the winter of 2013-2014, prevented seeds of this species from germinating and no living specimens were encountered during the surveys. Nonetheless, over a dozen dried milk-vetch seed pods were discovered in the southeastern quarter of the project site.

Two observations of the loggerhead shrike, not a covered species but considered sensitive by wildlife regulatory agencies, were recorded though no nests were found.

No blue-line stream corridors (streams or dry washes) were found within the project boundaries.

Therefore, no streambed alteration permits are required from the federal government.

With regard to mitigating impacts to sensitive species, the project site falls under the jurisdiction of the THCP. The Plan indicates the site lies outside Target Acquisition Areas and the Fluvial Sand Transport Process Area. Therefore, mitigation for impacts to all covered species described in this report consists of the payment of $2,371 per disturbed acre. The fee is paid to the Agua Caliente Band of Cahuilla Indians who, in turn, use the fee to purchase comparable habitat elsewhere in the Coachella Valley.

Following the implementation of the required and recommended mitigation described in this report, development of the project site is not expected to have significant adverse impacts upon sensitive species or other biological resources beyond the project site.

I. INTRODUCTION

On November 28, 2013, the firm of James W. Cornett - Ecological Consultants, Inc., was retained by Meridian Consultants to conduct a biological survey and analysis on an approximately 577-acre site located within the Agua Caliente Band of Cahuilla Indians Reservation and within the sphere of influence of the City of Rancho Mirage, Riverside County, California. The project site encompassed the majority of Section 24, Range 5 East, Township 4 South (San Bernardino Baseline and Meridian). The regional location is shown in Figure 1, the area location in Figure 2 and the specific location with project boundaries in Figure 3. Site photographs are shown in Figures 4-7.

This study was included as part of an environmental assessment mandated by the National Environmental Policy Act (NEPA) and the City of Rancho Mirage, Riverside County, California.

The biological survey and impact analysis were designed to ascertain the impacts of development on the biological resources of the project site and immediate vicinity.

Specific purposes of the biological surveys and impact analyses are listed below.

1. D etermine the vascular plant and vertebrate animal species that occur on, and immediately adjacent to, the project site.

2. A scertain the presence of any plant or animal species given special status by the federal government or the Agua Caliente Band of Cahuilla Indians as stated in the Tribe’s Habitat Conservation Plan (THCP).

3. A scertain the existence of other significant biotic elements, corridors or communities.

4. Consider the site’s biological resources as they relate to the THCP.

5. If necessary and where feasible, recommend measures to mitigate significant adverse impacts of the project on any sensitive species determined to occur within the project boundaries, unique biotic elements or unique biological communities. 12-1607

II. SITE AND PROJECT DESCRIPTIONS

Climate
The project area lies within the confines of a geographical region known as the Colorado Desert (Jaeger, 1957). As is typical of this subdivision of the Sonoran Desert, annual rainfall averages less than six inches (National Climatic Center, 2013). Most precipitation falls during the winter and late spring with occasional summer storms accounting for approximately one fifth of the annual total. Winter days are mild, averaging 71 degrees Fahrenheit. Winter nights occasionally drop to near freezing. The month of July brings the hottest temperatures with daytime highs averaging 109 degrees F.

Physical Features

The elevation of the project site ranges from approximately 252 feet above sea level at the northeast corner of the project site rising to 353 feet near the southeast corner. The only topographical relief consists of sand hummocks that rise from one to four feet above their base.

The hummocks have been formed by shrubs that interrupt the flow of sand carrying wind coming from the northwest off the Whitewater River Floodplain. The shrubs reduce wind velocity and result in sand deposits or "hummocks" on the leeward or easterly side of the shrubs. The environment of the project site is included as part of the sand field habitat of the valley floor as described in the THCP.

There are no naturally occurring springs or permanent aquatic habitats within the project site boundaries. No blue-line stream corridors (streams or dry washes) are shown on U.S. Geological Survey maps for the project site nor are there botanical indicators of such corridors. Thus, there appear to be no need to obtain streambed alteration permits from the federal government.

Soil characteristics are uniform over the entire site. Soil is composed of wind-blown alluvium created by persistent air movements from the northwest. This process increased in intensity with the drying out of the Coachella Valley at the close of the Pleistocene epoch ending 10,000 years before present. At the current time residential and commercial developments to the west and north have resulted in some sand stabilization on portions of the site.

Surrounding Lands

To the east of the project site is located Bob Hope Drive, a relatively busy four-lane thoroughfare. To the east of Bob Hope Drive is the Agua Caliente Resort Spa and relatively undisturbed habitat similar to the project site (see Figure 3).

12-1612
Rancho Mirage Section 24 Biological Study Page 10

Dinah Shore Drive, another relatively busy four-lane thoroughfare, forms the southern boundary of the project site. Immediately south of Dinah Shore Drive is a golf course and residential development.

Another golf course and residential development are located along the western boundary of the project site.

Ramon Road, a busy four-lane thoroughfare, forms the northern site boundary. Relatively undisturbed creosote scrub habitat, similar to the project site, lies immediately north of Ramon Road.

The project site is nearly an ecological island bounded on all four sides by paved roadways (three of them carrying high volumes of traffic) and on two sides by residential developments. These undoubtedly severely limit the movement of small terrestrial animals on and off the project site.

Existing Impacts

The area has been impacted by human developments and activities on all boundaries of the project site. A residential development to the west has lifted and shielded the site from prevailing westerly winds emanating from the San Gorgonio Pass. This has had the effect of reducing wind- carried sand resulting in the partial stabilization of sand deposits across some of the project site.

Native vegetation has been removed from approximately forty acres in the northwestern corner of the site when sand was excavated to provide fill for freeway interchanges in 2010. Native vegetation has also been removed and soils compacted on the northeastern corner of the project site (approximately 40 acres) to create a temporary parking lot. Another approximately 40 acres in the southwestern corner of site has received large mounds of fill dirt in the past decade.

Several elevated bill boards have been installed along the eastern and southern edges of the site.

Unpaved access roads parallel the eastern and southern boundaries.

A four-foot high sand fence has been installed along the southern project boundary.

The entire project area has been inundated with the exotic and invasive Sahara mustard, Brassica tournefortii. The establishment of this non-native, ephemeral species has likely contributed to the stabilization of blowsand on the project site.

Project Description (Provided by Meridian Consultants)

The Agua Caliente Band of Cahuilla Indians (“Tribe”) intends to prepare an Environmental Impact Statement (EIS) for the proposed Section 24 Specific Plan in compliance with the Agua

12-1613
Rancho Mirage Section 24 Biological Study Page 11

Caliente Tribal Environmental Policy Act (Tribal Ordinance No. 28). The Tribe is acting as the lead agency for the preparation of the EIS as the Section 24 Specific Plan area is located within the boundaries of the Agua Caliente Indian Reservation.

The Specific Plan area is located within the Sphere of Influence of the City of Rancho Mirage as identified by the Riverside Local Agency Formation Commission (LAFCO). Following action on the EIS and Section 24 Specific Plan by the Tribe, the Specific Plan area may be annexed to the City of Rancho Mirage.

The Tribe and Pulte Home Corporation/SCC Rancho Mirage Holdings LP (“Pulte/SCC”) are proposing the Section 24 Specific Plan to coordinate the planning and future development of the Specific Plan area, which consists of land under separate ownerships, including approximately 120 acres located on Ramon Road that is owned by the Tribe, approximately 97 acres located on Bob Hope Drive that is allotted to members of the Tribe and under contract to be acquired by the Tribe, approximately 40 acres located on the corner of Bob Hope Drive and Dinah Shore Drive that is allotted to members of the Tribe, and 320 acres located north of Dinah Shore Drive that is currently allotted to members of the Tribe and under contract to be acquired by Pulte Homes/SCC and developed as an active adult residential community for residents aged 55 and above.

The Section 24 Specific Plan would allow development of a mix of retail, entertainment, office, hotel and residential uses intended to complement existing and planned surrounding uses in the City of Rancho Mirage. The Section 24 Specific Plan would create eight Planning Areas and a circulation system planned to support the proposed uses. Commercial uses are proposed on Ramon Road and Bob Hope Drive with residential uses proposed for the remainder of the Specific Plan area.

An active adult residential community, containing up to 1,200 units, is proposed on the 312 acres located north of Dinah Shore Drive. The Specific Plan will include development standards and design guidelines for this new residential community. Planning Area 8 will be the first portion of the Specific Plan area to develop, with full development anticipated to occur within 6-8 years.

No timeframes have been identified for development of the remaining Planning Areas, which are being programmatically planned at this time to coordinate streets and other infrastructure, and to ensure the comprehensive land use planning of the Specific Plan area in relation to existing and planned surrounding uses. The Specific Plan will include development and design standards for the Ramon Road, Bob Hope Drive and Dinah Shore Drive frontages to promote compatibility with surrounding uses. The land uses that would be allowed by the proposed Specific Plan in Planning Areas 1-7 are described below.

The proposed Specific Plan will allow approximately 67 acres of multi-family residential development, at a density of up to 18 dwelling units per acre, in Planning Areas 1B, 2B, 5, 6B and 7B. Up to 1,206 multi-family residential units would be allowed by the proposed Specific

12-1614
Rancho Mirage Section 24 Biological Study Page 12

Plan in these areas. Retail commercial uses would be allowed in Planning Area 3, located on the corner of Ramon Road and Bob Hope Drive and Planning Area 7A, located on the corner of Bob Hope Drive and Dinah Shore Drive.

The Specific Plan would allow development of up to 777,000 square feet (s.f.) of development on the 51 acres designated for retail commercial uses. Resort flex uses, a mix of hotel, retail commercial and entertainment uses, would be allowed in Planning Areas 1A, 4 and 6A on Ramon Road and Bob Hope Drive. Up to 1,271,600 s.f. of retail commercial, hotel, and entertainment uses would be allowed on the 73 acres designated for resort flex uses. Planning Area 2A, centrally located on Ramon Road, would be designated Mixed Use Core, with up to 1,090,000 s.f. of development allowed on this 25 acres. This land use designation would allow a mix of uses, including community retail commercial uses, office, and attached residential units.

In total the Specific Plan would allow a maximum of 2,406 residential dwelling units and 3,138,000 square feet of commercial development.

III. STUDY METHODS

Prior to the initiation of field work, reviews of the literature and institutional records were conducted to determine the biological resources that might exist within the general area and to determine the possible occurrence of special status species. Records, collections, websites and/or staff of the University of California at Riverside Herbarium, the Boyd Deep Canyon Desert Research Center and the Coachella Valley Association of Governments were consulted for specific information as to the occurrence of selected species. A California Department of Fish & Game Natural Diversity Database (updated, March, 2014) check was also reviewed.

Field surveys were initiated in February of 2014. Specific dates of biological surveys were February 10, 11, 12, 14, 15, 16, 18, 19, 20, 21, 23, 24, 25, 26 and 27; and March 1, 2, 22 and 23, 2014. Night surveys were conducted on the evenings of February 19 and 24, 2014.

Survey dates were in late winter and early spring when all plant species and resident vertebrate species can be detected when maximum daytime air temperatures exceed 80° F. (Most days exceeded 80° during field surveys.) Reducing the likelihood that any species would be detected was the existence of unusually dry winters in 2012, 2013 and 2014. Drought dictates against the germination of ephemeral plant species and reproduction and survival in all animal species. In spite of severe long-term drought, it was concluded that this phenomenon did not impact the findings in this report because of evidence of sensitive species that was discovered and historical information regarding the biota of the project site.

Surveys were conducted by walking east/west transects at 10-yard intervals through the project site. The survey pattern used has been approved by the U.S. Fish & Wildlife Service for determining the presence or absence of the burrowing owl and desert tortoise and represents an intensive survey effort that resulted in no officially listed or federally protected species being overlooked (see Results section).

Private properties surround Section 24 prohibiting offsite surveys. Inability to conduct offsite surveys was considered inconsequential because very busy four-lane thoroughfares exist on the north, south and east boundaries of the project site. In addition, a walled residential community forms the western boundary. These barriers dramatically reduce dispersal movements of species on and off the site, particularly small terrestrial vertebrates.

Animal surveys were conducted simultaneously with plant surveys. In addition, twenty-five live-animal traps (which capture animals unharmed) for large and small mammals were set within the project site for twenty-four hour periods on February 19 and 24, 2014.

In an effort to determine if large animal corridors existed on the project site special attention was given to observing and identifying animal tracks. In addition, sand sifting and smoothing was done in several areas so that tracks would be more prominent and identifiable. Road kills on surrounding paved roadways were also monitored on all site visits.

12-1616
Rancho Mirage Section 24 Biological Study Page 14

Invertebrate sampling was conducted on the evenings of February 19 and 24, 2014. Three Bioquip Light Traps were used for attracting and live-capturing flying insects and some terrestrial arthropods. Black lights were the attracting mechanism with each trap powered by a 12-volt automobile battery. Traps were placed for maximum visibility.

Although scientific name changes occur as new discoveries are made in plant and animal taxonomy, the scientific names used in this report are taken from the standard and most available references describing the species found in the desert regions of Southern California—Bruce G.

Baldwin’s The Jepson Manual (Second Edition) published in 2012; D. P. Tibor's Inventory of rare and endangered vascular plants of California published in 2001; R. A. Stebbins' A field guide to western reptiles and amphibians published in 2003; Peterson's Bird of North America published in 2008; and E. W. Jameson’s and H. J. Peeters’ California mammals published in 2004. Plant common names used in this report are taken from Baldwin (2012), Jaeger (1969) and Tibor (2001). Animal common names are taken from Stebbins (2003), Peterson (2008) and Jameson and Peeter (2004).

Fieldwork was conducted by James Cornett (M.S., biology) and Walter Millin (B.A., environmental studies). Plant identifications were made by Andrew Sanders and Mr. Cornett.

Animal remains were identified by Robert Reynolds and Mr. Cornett. The literature review was conducted by Terry Belknap. The report was written by Mr. Cornett.

IV. PLANT SURVEY RESULTS

A single plant association or community was found on site: the Sonoran creosote bush scrub community as described by Sawyer Keeler-Wolf (1995).

Sonoran creosote bush scrub community dominates vegetation of the entire area and is the pervasive plant community throughout the Colorado Desert of southeastern California. The creosote bush (Larrea tridentata) is, by far, the dominant perennial followed by Emory's Dalea (Dalea emoryi), wingscale (Atriplex canescens) and croton (Croton californicus).

Approximately 25% of the project site has been disturbed by road shoulder clearing, removal of topsoil for fill, grading for a temporary a parking lot and fill piling. The vegetation of these areas is dominated by weed species that germinate and grow following the damage or removal of native vegetation. Within the project area such species include Sahara mustard (Brassica tournefortii), Emory's Dalea (Dalea emoryi) and croton (Croton californicus). These species are often found throughout the California deserts wherever the natural vegetation has been removed. (The Sahara mustard is also established in undisturbed areas of the project site.)

The Inventory of Rare and Endangered Vascular Plants of California, published by the California Native Plant Society (2001), the CNDDB Special Plant List (2013) or the Endangered, Threatened, and Rare Plants of California (2013) lists a total of four plant species that could conceivably occur on the project site. They are the glandular ditaxis (Ditaxis clariana), ribbed cryptantha (Cryptantha costata), flat-seeded spurge (Chamaesyce platysperma), and Coachella Valley milk vetch (Astragalus lentiginosus coachellae).

1. The glandular ditaxis is a very rare perennial herb that blooms from December through March.

It is restricted to sandy environments in the Sonoran Desert and has been found in the Coachella Valley at elevations similar to those found on the project site. Since the glandular ditaxis is a perennial, it is likely that it would be detected during the plant surveys. It was not detected and therefore presumed to not occur onsite. This species is not listed as rare, threatened or endangered by either the state or federal governments nor is it proposed to be listed at this time.

2. The ribbed cryptantha is an uncommon ephemeral known to occur on sandy soils in the Coachella Valley. The project site can be considered suitable habitat for this species. It was not detected but the surveys were done following an early winter period of below-average precipitation when most ephemerals would not be detected. The ribbed cryptantha is not listed as rare, threatened or endangered by either the state or federal governments nor is it proposed to be listed at this time.

3. The flat-seeded spurge is an extremely rare ephemeral herb known to occur on sandy soils in the Sonoran Desert. There has been at least one specimen found in the Coachella Valley. The species was not detected but the surveys were done in a winter of below-average precipitation.

12-1618
Rancho Mirage Section 24 Biological Study Page 16

The flat-seeded spurge is not listed as rare, threatened or endangered by either the state or federal governments nor is it proposed to be listed at this time.

4. The Coachella Valley milk vetch is an uncommon, spring-blooming ephemeral herb that is known to occur on sandy soils in the Coachella Valley. No living individuals of this subspecies were detected on or near the project site. However, many seed pods of this species were found and the area where they were located has been mapped and shown in Figure 3. Prior surveys on the project site in 2011 revealed 309 living individuals of this species within the project boundaries (Cornett, 2011). The project site appears to have a large seed bank of this species within the sandy soil and it is considered to be present today within the project boundaries.

No additional plant surveys are recommended. The only officially listed plant species that is considered to be present (as seed) is the Coachella Valley milk vetch. The milk vetch is listed as endangered by the U.S. Fish & Wildlife Service.

A complete list of vascular plant species found within the project boundaries has been placed in Table 1 of the Appendix. Taxonomic nomenclature follows Baldwin (2012). Common names are taken from Jaeger (1969), Baldwin (2012), Munz (1974) or Tibor (2001).

12-1619
Rancho Mirage Section 24 Biological Study Page 17

V. ANIMAL SURVEY RESULTS

The fauna of the project site and surrounding vicinity is composed of species typical of sandy, windswept habitats in the Coachella Valley portion of the Colorado Desert as defined by Jaeger (1957). Animal species associated with residential subdivisions were also recorded from the site.

Arthropods
Encountered arthropods on the site included the sand scorpion (Paruroctonus mesaensis), Eleodes beetle (Eleodes armata), harvester ant (Pogonomyrmex californicus) and creosote bush grasshopper (Bootettix argentatus).

Three insect species known to occur within the Coachella Valley have been placed on the California Department of Fish and Game’s Special Animals list. They are the Coachella giant sand treader cricket (Macrobaenetes valgum), Coachella Valley Jerusalem cricket (Stenopelmatus cahuilaensis) and Coachella Valley grasshopper (Spaniacris deserticola). None of these three insect species were found during the surveys and none have any official status with the federal government. The Coachella giant sand treader cricket and Jerusalem cricket are covered species under the THCP.

Amphibians and Reptiles

No amphibian species were found during the surveys and none are expected.

Detected reptiles included the side-blotched lizard (Uta stansburiana), western whiptail (Cnemidophorus tigris), desert iguana (Dipsosaurus dorsalis), western shovel-nosed snake (Chionactis occipitalis) and sidewinder (Crotalus cerastes).

Six observations of the federally threatened Coachella Valley fringe-toed lizard, Uma inornata, were recorded (February 10, 11, 12, 18, 20, 26, 2014). Suitable habitat (surfaces of loose, windblown sand) for the lizard exists across the entire site with the exception of the temporary parking area in the northeast corner (approximately 40 acres). With this single exception, the lizard should be expected throughout the project site.

A concerted effort was made to locate sign of the officially listed desert tortoise (Goperhus agassizi). However, no evidence of any kind was found and no direct observations were made.

In addition, the California Natural Diversity Database (March, 2014) has no records of the tortoise on or within one mile of the project site. It is therefore concluded that this species does not occur within the project site and immediate vicinity and no additional surveys for this species are recommended.

12-1620

An intensive effort was also made to locate individuals or sign of the flat-tailed horned lizard, Phrynosoma mcallii. A single individual was found (February 16, 2014). Most of the project site is considered suitable habitat for this species and it may be more widespread than the discovery of a single specimen would indicate. The surveys were done in late winter and many individuals might still be in hibernation. In 2011, the U.S. Fish & Wildlife Service considered listing the flat- tailed horned lizard but elected to not do so in May of that year.

Birds

Frequently detected birds within the project area were the common raven (Corvus corax), greater roadrunner (Geococcyx californianus), mourning dove (Zenaida macroura), house finch (Carpodacus mexicanus) and Say’s phoebe (Sayornis saya).

No observations of LeConte’s thrasher (Toxostoma lecontei) were recorded during the surveys.

In the Coachella Valley this species is closely associated with golden cholla, an arborescent cactus that provides a nesting site for the thrasher. The cactus species is absent from the project area and, therefore, it was concluded the thrasher does not occupy the project site at this time.

LeConte’s thrasher is a covered species under the THCP but is not listed by the USFWS.

Two sensitive avian species were observed within the project boundaries: the burrowing owl (Athene cunicularia) and loggerhead shrike (Lanius ludovicianus).

Burrowing Owl

The burrowing owl was recorded within project site boundaries on six separate days: February 11, 16, 24, 25, and 26 and March 1, 2014. (see Figure 3 for locations). All observations were of adult birds. One active burrow was found on the project site. The entire project site is considered potential habitat for the burrowing owl.

According to the THCP, the burrowing owl is not a covered species within the Valley Floor Conservation Area. However, it is protected in the United States by the Migratory Bird Treaty Act of 1918. Mitigation of impacts to the owl is required under the Act.

Loggerhead Shrike

The loggerhead shrike was observed on two occasions within the project site boundaries:

February 20 and March 2, 2014. The locations are shown in Figure 3. No old or new nests were found but the species is likely resident in the project area because of suitable habitat and prey.

According to the THCP, the loggerhead shrike is not a covered species and has no special federal status. It is considered a Species of Special Concern by the state of California.

Rancho Mirage Section 24 Biological Study Page 19

Mammals

Recorded mammals included the black-tailed jackrabbit (Lepus californicus), Palm Springs ground squirrel (Spermophilus tereticaudus chlorus), desert kangaroo rat (Dipodomys deserti) and coyote (Canis latrans). No individuals of the Palm Springs Pocket Mouse (Perognathus longimembris bangsi), a covered species, were found.

The Palm Springs Ground Squirrel is the only mammalian covered species discovered within the project boundaries. It was only detected twice (February 25, 26, 2014) but should be expected throughout the project site as the habitat is suitable. It currently is not a listed species and has a much broader range than was previously thought (Federal Register, 2009). It is, therefore, unlikely that it will be listed in the foreseeable future.

Wildlife Corridors

Smoothing of surfaces to yield tracks was performed on each site visit to determine if important wildlife corridors existed on the site. Much of the project site was sampled using this technique.

Tracks of ravens, roadrunners, coyotes and black-tailed jackrabbits were each recorded.

However, no discernable and routinely used corridors could be found.

A complete list of vertebrate species observed or detected on the project site can be found in Table 2 of the Appendix.

12-1622
Rancho Mirage Section 24 Biological Study Page 20

VI. FINDINGS AND RECOMMENDATIONS

Intensive plant and animal surveys were conducted within the boundaries of the proposed project site. Four sensitive species were detected that are classified as covered species in the Valley Floor Conservation Area of the THCP. The covered species are Coachella Valley milk vetch, Coachella Valley fringe-toed lizard, flat-tailed horned lizard and Palm Springs ground squirrel.

Under the THCP adverse impacts to these four species can be mitigated by the project proponent paying the Tribe the required mitigation fee of $2,371 per disturbed acre for all covered species.

Collected fees are used to purchase and preserve comparable habitat elsewhere in the Coachella Valley.

Three additional covered species may also occur within the project site but were not detected during the surveys. They are the Coachella giant sand treader cricket, Coachella Valley Jerusalem cricket and Palm Springs pocket mouse. Any adverse impacts to these three species are mitigated by paying the habitat mitigation fee described in the previous paragraph. Impacts to all covered species are mitigated by the payment of the one-time fee of $2,371 per acre.

Burrowing Owl

The burrowing owl was observed six separate times within the project site boundaries. One active burrow was found. According to the THCP the burrowing owl is not a covered species in the Valley Floor Conservation Area (HTCP, page 1-3). However, the Migratory Bird Act prohibits harming the owl therefore mitigation of potential adverse impacts are required. Owl mitigation is provided in the Staff Report on Burrowing Owl Mitigation prepared by the California Department of Fish and Game on March 7, 2012, and approved and accepted by the U.S. Fish & Wildlife Service. Mitigation for the owl is summarized below.

1. A preconstruction survey should take place not more than 30 days prior to project grading to determine the location of active burrows on and within 550 yards of an approved project site. If no active burrows are found in the survey area, site disturbance may commence providing a biological monitor is onsite.

2. A biological monitor, with the authority to halt or redirect grading, should be present whenever grading or construction vehicles are present and operating on the project site.

The function of the monitor is to protect burrowing owls that arrive on or near the project site after the clearance survey and during the construction period

3. The breeding season of the western burrowing owl is from February 1 through August 31 of each year. No construction disturbances of any kind should occur within 500 meters (550 yards) of an active burrow during this time period. Thus, on a project site, grading should take place from September 1 through January 30 of each year to avoid restriction or cancellation of grading because of the presence of burrowing owls during the breeding season.

12-1623
Rancho Mirage Section 24 Biological Study Page 21

4. Resident owls present on or near the project site outside the breeding season can, in some instances, be relocated to other sites by a permitted biologist under the authorization of the U.S. Fish and Wildlife Service.

Loggerhead Shrike

According to the THCP, the loggerhead shrike is not a covered species and has no special federal status. It is considered a Species of Special Concern by the state of California. Mitigating impacts to the shrike is not required under federal statutes or the THCP. Nevertheless, it is recommended that breeding surveys be conducted simultaneously with burrowing owls surveys 30 days prior to any construction activities that are planned between February 15 and June 15, breeding seasons for both species. If a shrike nest is found, a buffer should be established in which construction activities are prohibited until all young have fledged. The width of the buffer should be determined by a qualified biologist.

Indirect Impacts

The project site is surrounded by high-volume roadways and two residential developments. As a result, it is nearly an ecological island with likely little significant biological interaction with natural habitats elsewhere in the Coachella Valley. Therefore, it is concluded that the development of the project site will have no significant indirect impacts to biological resources in the region.

Conclusion

Development of the proposed project site is not anticipated to have significant adverse impacts upon biological resources in the region providing the mitigation described in this report is implemented.

1.1 Purpose and Scope
This soils/geology review is for the proposed “ Section 24 Specific Plan ” project located in the Rancho Mirage area of Riverside County, California (see Figure 1) .

Our scope of services for this review included the following:
 Review of sequential pairs of aerial photographs and our in-house and relevant published data for this area (see references at the end of this report).  A site geologic reconnaissance and visual observations of surface conditions.  Excavation, sampling and logging of 9 exploratory geotechnical hollow stem auger borings throughout the site. Logs of test borings are presented in Appendix A.
 Laboratory testing of representative soil samples obtained from the subsurface exploration program. A brief description of laboratory testing procedures and laboratory test results are presented in Appendix B.  Geotechnical engineering analyses performed or as directed by a California registered Geotechnical Engineer (GE) including preliminary foundation and seismic design parameters based on the 2013 California Building Code (CBC). A California Certified Engineering Geologist (CEG) performed engineering geology review of site geologic hazards.
 Preparation of t his report which presents the results of our review and provides preliminary geotechnical recommendations for the proposed development.

This report is not intended to be used as an environmental site assessment (Phase I or other).

1.2 Site Location and Description
The project site is located on several contiguous undeveloped parcels (Assessor P
arcel Numbers (APNs) 673- 120-021; -022; - 023; - 024; and - 025), totaling approximately 577.33 acres (gross). The property is located southwest of the intersection of Ramon Road and Bob Hope Drive, north of Dinah Shore Drive, east of Los Alamos Road in an unincorporated portion of Riverside County, California (within the sphere of influence of the City of Rancho Mirage). The approximate limits of the site are shown on the Site Location Map, Figure 1. The property is 12-1640

located immediately west of the Aqua Caliente Casino Resort Spa; north and east of the Westin Mission Hills resort community and northwest of Desert Ridge Plaza shopping center.

Topographically, the site and surrounding area slopes to the north and north-east.

Site elevations range from high point elevation of approximately 356 feet above mean sea level (msl) near the southwestern corner to a low point elevation of approximately 248 feet (msl) near the northeast corner of the property.

The site is currently vacant land characterized with typical sand dune topography .

It appears that a borrow source was located along the central western boundary and as well as an area for soil stockpiling in the southwest corner. Remnants of gravel parking lot are located at northeast corner, adjacent to intersection of Bob Hope Drive and Ramon Road.

1.3 Proposed Development
Based on a provided project description and conceptual plan by MSA Consulting , we understand that the proposed mix-use development will consist of retail, entertainment, office space, resort, residential lots, park sites, open spaces, se
veral lakes and associated street improvements. Although structural loads are not known to us at this time, typical column loads for retail, office/hotel, and co
mmercial structures are expected to range up to 200 kips and perimeter bearing wall loads are to range up to 6 kips per lineal foot. We anticipate residential lots to h
ost a one- or two-story single or multi-family residential homes consisting of ty
pical wood-frame structure with slab-on-grade foundations.

We anticipate that site grading will include typical cut and fill grading to create level pads, access streets and maximum 3:1 (horizontal to vertical) slopes . Based on provided preliminary Earthwork Exhibit (ALT 10) prepared by MSA Consulting Inc. (MSA, 2014) the maximum proposed cut and fill thickness is on the order of 45 feet (cut
) to 50 feet (fill).

2.1 Field Exploration
Our field exploration program consist ed of 9 hollow-stem auger borings excavated at the approximate locations shown on the Geotechnical Map (Plate 1, Geotechnical Map). During excavation, bulk samples and relatively “undisturbed” Ring samples were collected from the exploration borings for further laboratory testing and evaluation. The relatively undisturbed samples were obtained utilizing a modified California drive sampler (2⅜-inch inside diameter and 3-inch outside diameter) driven 18 inches in general accordance with ASTM Test Method D3550.

Standard penetration tests (SPT) were performed using a 2-inch outside diameter (1⅜-inch inside diameter) sampler driven 18 inches in general accordance with ASTM Test Method D1586. The number of blows to drive the samplers are recorded on the boring logs for each 6-inch increment (unless encountering refusal or >50 blows per 6 inches). Sampling was conducted by a staff geologist from our firm. After logging and sampling, the excavations were loosely backfilled with spoils generated during excavation. The logs of exploratory test borings are presented in Appendix A.

2.2 Laboratory Testing
Laboratory tests were performed on representative bulk and undisturbed drive samples to provide a basis for development of remedial earthwork and geotechnical design parameters. Selected samples were tested for the following parameters: insitu moisture and density, maximum dry density (Proctor), R-Value, gradation, collapse, soluble sulfate, pH, resistivity and chloride content. The results of our laboratory testing are presented in Appendix B. 12-1642

The site is located within the Coachella Valley area in the Colorado Desert Geomorphic Province of California. The San Bernardino Mountains of the Transverse Ranges Geomorphic Province are to the north and the San Jacinto Mountains of the Peninsular Range are to the south. The dominant structural feature in this region is the active San Andreas transform system that consists of several major northwest-trending right lateral strike slip faults that extend through the San Gorgonio pass along the southern foothills of the San Bernardino Mountains, and along the northeast margin of the Coachella Valley. The San Andreas Fault Zone is composed of a series of fault zones of which the South Branch of the San Andreas is located in the vicinity, generally north of the site.

Fig
ure 2, Regional Geologic Map, depicts the fault location and shows the region as underlain by unconsolidated Holocene sediments (alluvium and other deposits).

The site itself is underlain by wind-blown (aeolian) sand deposits as well as alluvial soil eroded from the nearby mountains and deposited in the site vicinity.

3.2 Site Specific Geology
Based on the results of our field exploration and review of relevant geologic data for this area (see References), the site subsurface materials consist of dune sands over alluvium to the depths explored. Stockpiled undocumented fill soils are locally observed onsite. These units are discussed in the following sections in order of increasing age and further described on the logs of geotechnical borings in Appendix A.

3.2.1 Undocumented Fill (Map Symbol Afu)
As indicated above, a borrow source and associated grading was located along the central, western boundary and soil stockpiling was observed in the southwest corner. Grading to produce a large gravel parking field was also noted in the north east corner of the site. If encountered during site grading, undocumented fills are considered unsuitable for support of additional fill or structures or other planned improvements. T he undocumented fill soils appear to be generated from onsite or nearby sources; hence they should be generally suitable for use as compacted fills provided they are cleared of debris,
organics, and any deleterious materials.

3.2.2 Dune Sand (Map symbol Qs)
Dune sand materials are expected to mantle the majority of the site. The depth of the dune sand materials cannot be easily verified based on this limited investigation and relatively homogenous onsite alluvium. However, it is estimated that the dune sands generally extend to a depth varying from 5 to 20 feet below ground surface (BGS). These materials generally consist of light brown gray to darker gray and loose to medium dense silty sand to poorly-graded fine sand. Based on the results of our laboratory testing, these materials are expected to possess a very low expansion potential (EI<21) and N-values ranging from 5 to 15 blows/foot.

3.2.3 Quaternary Alluvium (Map Symbol Qal)
Quaternary-aged alluvial deposits were encountered in all of our borings to the maximum depth explored. As encountered, the alluvium typically consists of light brown to brownish gray, medium dense to very dense, poorly-graded fine sand to sand with silt. The alluvium is expected to generally possess very low expansion potential (EI<21).

3.3 Groundwater and Surface Water
Groundwater was not encountered in any of the borings and no standing water was o
bserved on the ground surface during the time of the investigation.

According to Department of water Resources, Southern District, Well 04S05E29A001S located west of the site, groundwater depths may be between 160 and 175 feet below ground surface (bgs). Based on this data, it appears that shallow groundwater has not been present recently, or historically. As such, groundwater is not expected to be a constraint to development of the site and considered to be no impact to this site. However, it should be noted that local perched water conditions may exist intermittently and may fluctuate seasonally, depending on rainfall and irrigation conditions . Surface runoff from the adjacent elevated portions of the site should be anticipated.

3.4 Faulting and Fissuring
This site is not located within a currently designated Alquist-Priolo Earthquake Fault Zone or County of Riverside Fault Zone. No active, inactive fault traces or fissuring are known to traverse the planned development portions (Bryant and Hart, 2007) and no evidence of onsite faulting was observed during our investigation. As defined by the California Geologic Survey, an active fault is one that has had surface displacement within the Holocene Epoch (roughly the last 11,000 years).

The closest known active fault zone is the Coachella Segment of the San Andreas Fault Zone located approximately, 5.0 miles (7.6 km) northwest of the site (Blake, 2000d). Twenty eight active faults are known to exist within 100 Km (62.4 miles) of the site. A table of the major active earthquakes (>5.5 Mw) within 20 miles of the site in the last 150 years is presented in the table below. The South Branch S
egment of the San Andreas Fault Zone is considered to be the source of the design earthquake. Due to the distance to active fault(s), ground rupture at this site is considered to be no impact.

Fault Segment Distance from Site Moment Magnitude
San Andreas 4.7 miles (7.6 Km) 7.1
Burnt Mountain 9.6 miles (15.5 Km) 6.4
Eureka Peak 11.8 miles (19.0 Km) 6.4
Pinto Mountain 20.3 miles (32.7 Km) 7.0

3.5 Ground Shaking
Strong ground shaking can be expected at the site during moderate to severe earthquakes in this general region. This is common to virtually all of Southern California and can be considered a significant impact. Intensity of ground shaking at a given location depends primarily upon earthquake magnitude, site distance from the source, and site response (soil type) characteristics. Based on t he 2013 California Building Code (CBC) and using the USGS Ground Motion Parameter Calculator, the seismic coefficients for this site are provided in the following table:

3.6 Dynamic Settlement (Liquefaction and Dry Settlement) Liquefaction and dynamic settlement of cohesionless soils can be caused by strong vibratory motion due to earthquakes. Research and historical data indicate that loose granular soils below a near-surface groundwater table are most susceptible to liquefaction. Due to the absence of shallow groundwater, the liquefaction-induced settlement is considered to be no impact for this site.

However, during a strong seismic event, seismically-induced settlement can still occur within loose to moderately dense, dry or saturated granular soils. Settlement caused by ground shaking is often non-uniformly distributed, which can result in differential settlement. Based on the proposed remedial grading recommendations in areas of planned development, the potential total settlement resulting from ground shaking is considered minimal or less than ½ inch in the upper 50 feet of soils. The seismically-induced ground settlement is considered to be less than significant impact when the recommendations contained herein are implemented.

3.7 Flooding
The site is not within a FEMA flood plain. However, the northeast portion of the site is within a Coachella Valley Water District flood hazard area (CVWD, 2014 and Northwest Hydraulics, 2014).

3.8 Seiche and Tsunami
Due to the sites elevated location and lack of nearby open bodies of water, the possibility of the seiches or tsunami is considered to be no impact for this site.

3.9 Expansive/Collapsible Soils
Limited laboratory testing indicated that onsite soils possess a very low expansion potential (EI<21). Based on the remedial grading recommendations in areas of planned development, the potential impact due to collapsible soils, if they exist onsite, is less than significant.

3.10 Slope Stability and Landslides
Cut and fill slopes are currently planned on the order of approximately 20 feet high at inclinations of 3:1 (horizontal to vertical). As such, slope instability is not considered an issue at th is site. The site is not considered susceptible to seismically induced landslides and therefore there is no impact for this site. 12-1646

4.0 S U M M A R Y O F F I N D I N G S A N D C O N C L U S I O N S Based on the results of this review, it is our opinion that the proposed development is feasible from a geotechnical/geologic standpoint. The following is a summary of the m
ain geotechnical findings or factors that may affect development of the site.  The existing onsite soils appear to be suitable for reuse as fill during proposed grading provided they are relatively free of organic material and debris.  Undocumented fill soils (existing stockpiled soils), topsoil, and loose dune sand are considered to be potentially compressible. These materials should be recompacted in areas of planned development.
 The near surface soils are potentially compressible in their present state and may settle under the surcharge of fills or foundation loading. As such, these materials should be removed (over-excavated) and re-compacted in all settleme nt- sensitive areas based on specific building loads and settlement criteria for individual structures.
 Based on our subsurface exploration, it is our opinion that the onsite earth materials can be excavated with heavy-duty conventional grading equipment in good working condition.
 Evidence of active faulting was not identified within or projecting into the planned development area. Strong ground shaking may occur at this site due to local earthquake activity.
 Groundwater was not encountered; however, perched groundwater may develop in areas of soils with contrasting permeabilities possibly resulting in saturated soil conditions.
 Based on preliminary laboratory results and field observations, onsite earth materials are expected to possess a very low expansion potential and negligible sulfate exposure to concrete.
 Cut/Fill slopes are anticipated to be less than 20 feet in height and are expected to be grossly stable.

Due to the cohesionless nature of site soils, surficial erosion should be anticipated.
 Unprotected pads and slope faces will be susceptible to erosion. This risk can be r educed by planting the slopes as soon as possible after grading, and by maintaining proper erosion control measures.
 A relative small low lying northeast portion of the site is located within a local CVWD Flood Hazard area. The design civil engineer should review this condition an
d address the flood design mitigation.

5.0 R E C O M M E N D A T I O N S

5.1 General
Based on the results of th is review, it is our opinion that the subject site is suitable for the proposed development from a geotechnical viewpoint. Design and grading of the site should be in accordance with our recommendations included in this report
and based on additional site-specific development plans and evaluations made during design and construction by the geotechnical consultant.

5.2 Earthwork Considerations
Earthwork should be performed in accordance with the General Earthwork and Grading Specifications in Appendix C as well as the following recommendations.

The recommendations contained in Appendix C, are general grading specifications provided for typical grading projects and some of the recommendations may not be strictly applicable to this project.

The specific recommendations contained in the
text of this report supersede the general recommendations in Appendix C.

The contract between the developer and earthwork contractor should be worded such that it is the responsibility of the contractor to place the fill properly in accordance with the recommendations of this report, and applicable County Grading Ordinances, notwithstanding the testing and observation of the geotechnical consultant during construction.

5.2.1 Site Preparation and Remedial Grading
Prior to grading, the proposed structural improvement areas (i.e. all structural fill areas, pavement areas, buildings, etc.) of the site should be cleared of surface and subsurface obstructions, heavy vegetation and boulders. Roots and debris should be disposed of offsite. Septic Tanks or seepage pits, if encountered, should be abandoned in accordance with the County of Riverside Department of Health Services guidelines.

The near surface soils are potentially compressible in their present state and may settle under the surcharge of fills or foundation loading. As such, these materials should be removed (over-excavated) and re-compacted in all settlement-sensitive areas in accordance with specific building loads and/or
settlement criteria for individual structures. In general, it is estimated that with pre-watering to optimum moisture condition to depths of 5 to 7 feet below existing grades (in fill areas) the planned remedial removal depths may range from 3 to 5 feet below bottom of footings for most buildings. In 12-1648
Soils/Geology Review May 15, 2014
Section 24 Specific Plan - Rancho Mirage Area, Riverside County, California Project No. 10143.003

- 10 -
general, the depth of removal should be anticipated to extend to 3 feet below street subgrade, pad subgrade or footing bottom, or whichever is deeper. However, such criteria should be further verified based on review of future site development plans and foundation loads.

Acceptability of all removal bottoms should be reviewed by the geotechnical consultant and documented in the as-graded geotechnical report. The removal limit should be established by a 1:1 (horizontal: vertical) projection from the edge of fill soils supporting settlement-sensitive structures downward and outward to competent material identified by the geotechnical consultant. Removal will also include benching into competent material as the fills rise. Areas adjacent to existing structures or property limits may require special considerations and monitoring. Steeper temporary slopes in these areas may be considered.

5.2.2 Cut/Fill Transition Lots
In order to mitigate the impact of underlying cut/fill transition conditions, we recommend over-excavation of the cut portion of transition lots. Over- excavation should extend to a minimum depth of 3 feet below the bottom of the proposed footings or one-half of the maximum fill thickness on the lot, whichever is deeper (not to exceed 10 feet). This overexcavation does not include scarification or preprocessing prior to placement of fill.

5.2.3 Structural Fills
The onsite soils are generally suitable for re-use as compacted fill provided they are free of debris and organic matter. Areas to receive structural fill and/or other surface improvements should be scarified to a minimum depth of 8 inches, conditioned to at least optimum moisture content, and recompacted. Fill soils should be placed at a minimum of 90 percent relative compaction (based on ASTM D1557) and near or above optimum moisture content. Placement and compaction of fill should be performed in accordance with local grading ordinances under the observation and testing of the geotechnical consultant. The optimum lift thickness to produce a uniformly compacted fill will depend on the type and size of compaction equipment used. In general, fill should be placed in uniform lifts not exceeding 8 inches in thickness.

Fill slope keyways will be necessary at the toe of all fill slopes and cut slope replacement fills. Keyway schematics, including dimensions and subdrain recommendations, are provided in Appendix C . All keyways should be excavated into dense bedrock or dense alluvium as determined by the geotechnical engineer. The cut portions of all slope and keyway excavations should be geologically mapped and approved by a geologist prior to fill placement.
12-1649
Soils/Geology Review May 15, 2014
Section 24 Specific Plan - Rancho Mirage Area, Riverside County, California Project No. 10143.003

- 11 -
Fills placed on slopes steeper than 5:1 (horizontal:vertical) should be benched into dense soils (see Appendix C for benching detail). Benching should be of sufficient depth to remove all loose material. A minimum bench height of 2 feet into approved material should be maintained at all times.

5.2.4 Shrinkage and Subsidence
The volume change of excavated onsite materials upon compaction is expected to vary with materials, volume of roots and deleterious materials, density, insitu moisture content, location, and compaction effort. The in- place and compacted densities of soil materials vary and accurate overall determination of shrinkage and bulking cannot be made. Therefore, we recommend site grading include, if possible, a balance area or ability to adjust import quantities to accommodate some variation. Based on our experience with similar materials, we anticipate 12 to 15 percent shrinkage in the upper 5 to 10 feet of dune sand/alluvium.

Subsidence due solely to scarification, moisture conditioning and recompaction of the exposed bottom of overexcavation, is expected to be on the order of 0.10 foot. This should be added to the above shrinkage value for the recompacted fill zone, to calculate overall recompaction subsidence.

5.2.5 Import Soils
Import soils and/or borrow sites, if needed, should be evaluated by the geotechnical consultant prior to import. Import soils should be uncontaminated, granular in nature, free of organic material (loss on ignition less-than 2 percent), have a very low expansion potential (with an Expansion Index less than 21) and have a low corrosion impact to the proposed improvements.

5.2.6 Utility Trenches
Utility trenches should be backfilled with compacted fill in accordance with Sections 306-1.2 and 306-1.3 of the Standard Specifications for Public Works Construction, (“Greenbook”), 2012 Edition (or most recent). Fill material above the pipe zone should be placed in lifts not exceeding 8 inches in uncompacted thickness and should be compacted to at least 90 percent relative compaction (ASTM D 1557) by mechanical means only.

Site soils may generally be suitable as trench backfill provided these soils are screened of rocks over 1½ inches in diameter and organic matter. If imported sand is used as backfill, the upper 3 feet in building and pavement areas should be compacted to 95 percent. The upper 6 inches of backfill in all pavement areas should be compacted to at least 95 percent relative compaction.
12-1650
Soils/Geology Review May 15, 2014
Section 24 Specific Plan - Rancho Mirage Area, Riverside County, California Project No. 10143.003

- 12 -
Where granular backfill is used in utility trenches adjacent moisture sensitive subgrades and foundation soils, we recommend that a cut-off “plug” of impermeable material be placed in these trenches at the perimeter of buildings, and at pavement edges adjacent to irrigated landscaped areas.

A “plug” can consist of a 5-foot long section of clayey soils with more than 35-percent passing the No. 200 sieve, or a Controlled Low Strength Material (CLSM) consisting of one sack of Portland-cement plus one sack of bentonite per cubic-yard of sand. CLSM should generally conform to Section 201-6 of the Standard Specifications for Public Works Construction, (“Greenbook”), 2012 Edition. This is intended to reduce the likelihood of water permeating trenches from landscaped areas, then seeping along permeable trench backfill into the building and pavement subgrades, resulting in wetting of moisture sensitive subgrade earth materials under buildings and pavements.

Excavation of utility trenches should be performed in accordance with the project plans, specifications and the California Construction Safety Orders (2012 Edition or more current). The contractor should be responsible for providing a "competent person" as defined in Article 6 of the California Construction Safety Orders. Contractors should be advised that sandy soils (such as fills generated from the onsite alluvium) could make excavations particularly unsafe if all safety precautions are not properly implemented. In addition, excavations at or near the toe of slopes and/or parallel to slopes may be highly unstable due to the increased driving force and load on the trench wall. Spoil piles from the excavation(s) and construction equipment should be kept away from the sides of the trenches. Leighton does not consult in the area of safety engineering.

5.2.7 Drainage
All drainage should be directed away from structures, slopes and pavements by means of approved permanent/temporary drainage devices.

Adequate storm drainage of any proposed pad should be provided to avoid wetting of foundation soils. Irrigation adjacent to buildings should be avoided when possible. As an option, sealed-bottom planter boxes and/or drought resistant vegetation should be used within 5-feet of buildings.

5.2.8 Slope Design and Construction
Based on our understanding and planning purposes, all fill and cut slopes will be designed and constructed at 3:1 (horizontal:vertical) with benches at maximum 30 foot intervals. These slopes are considered grossly stable for static and pseudostatic conditions. For planning purposes, cut slopes exceeding 5 feet in height should be constructed as replacement fill slopes due to the highly erosive nature of site soils. Future grading plans should be subject to further review and evaluation.
12-1651
Soils/Geology Review May 15, 2014
Section 24 Specific Plan - Rancho Mirage Area, Riverside County, California Project No. 10143.003

- 13 -
The outer portion of fill slopes should be either overbuilt by 2 feet (minimum) and trimmed back to the finished slope configuration or compacted in vertical increments of 5 feet (maximum) by a weighted sheepsfoot roller as the fill is placed. The slope face should then be track- walked by dozers of appropriate weight to achieve the final slope configuration and compaction to the slope face.

Slope faces are inherently subject to erosion, particularly if exposed to wind, rainfall and irrigation. Landscaping and slope maintenance should be conducted as soon as possible in order to increase long-term surficial stability. Berms should be provided at the top of fill slopes. Drainage should be directed such that surface runoff on the slope face is minimized

5.3 Foundation Design

5.3.1 Bearing and Lateral Pressures
Based on our analysis, the proposed residential/ and retail/commercial structures may be founded on conventional foundation systems based on the design parameters provided below . The proposed foundations and slabs should be designed in accordance with the structural consultants’ design, the minimum geotechnical recommendations presented herein, and the 2013 CBC. In utilizing the minimum geotechnical foundation recommendations, the structural consultant should design the foundation system to acceptable deflection criteria as determined by the architect.

Foundation footings may be designed with the following geotechnical design parameters:
 Bearing Capacity : A net allowable bearing capacity of 2,000 pounds per square foot (psf), or a modulus of subgrade reaction of 150 pci may be used for design of footings founded entirely into compacted fill.

The footings should extend a minimum of 12 inches below lowest adjacent grade. A minimum base width of 18 inches for continuous footings and a minimum bearing area of 3 square feet (1.75 ft by 1.75 ft) for pad foundations should be used. Additionally, an increase of one-third may be applied when considering short-term live loads (e.g. seismic and wind).
 Passive Pressures: The passive earth pressure may be computed as an equivalent fluid having a density of 300 psf per foot of depth, to a maximum earth pressure of 3,000 pounds per square foot. A coefficient of friction between soil and concrete of 0.35 may be used with dead load forces. When combining passive pressure and frictional resistance, the passive pressure component should be reduced by one-third
12-1652
Soils/Geology Review May 15, 2014
Section 24 Specific Plan - Rancho Mirage Area, Riverside County, California Project No. 10143.003

- 14 -
The footing width, depth, reinforcement, slab reinforcement, and the slab- on-grade thickness should be designed by the structural consultant based on recommendations and soil characteristics indicated herein and the most recently adopted edition of the CBC.

5.3.2 Settlement
For preliminary design purposes, the project civil engineer, structural engineer, and architect should consider the potential effects of both static settlement and dynamic settlement presented below.
 Static Settlement : Most of the static settlement of onsite soils is expected to be immediate or within 30 days following fill placement. A differential static settlement of 0.5 inch over a 40-foot span may be considered. Additional settlement will also occur in the future if sites grades are raised or due to specific or large footing/foundation loads.

 Dynamic Settlement: Based on our analysis, we estimate that total dynamic settlement is expected to be less than 0.5 inch . Differential settlement is expected to be minimal or less than 0.25 inches over a 40-foot horizontal span.

5.3.3 Vapor Retarder
It has been a standard of care to install a moisture retarder underneath all slabs where moisture condensation is undesirable. Moisture vapor retarders may retard but not totally eliminate moisture vapor movement from the underlying soils up through the slabs. Moisture vapor transmission may be additionally reduced by use of concrete additives. Leighton does not practice in the field of moisture vapor transmission evaluation/mitigation. Therefore , we recommend that a qualified person/firm be engaged/consulted with to evaluate the general and specific moisture vapor transmission paths and any impact on the proposed construction. This person/firm should provide recommendations for mitigation of potential adverse impact of moisture vapor transmission on various components of the structure as deemed appropriate.

The slab subgrade soils should be well wetted prior to placing concrete.

5.4 Retaining Walls
Retaining wall earth pressures are a function of the amount of wall yielding horizontally under load. If the wall can yield enough to mobilize full shear strength of backfill soils, then the wall can be designed for "active" pressure. If the wall cannot yield under the applied load, the shear strength of the soil cannot be mobilized and the earth pressure will be higher. Such walls should be designed for "at rest" conditions. If a structure moves toward the soils, the 12-1653
Soils/Geology Review May 15, 2014
Section 24 Specific Plan - Rancho Mirage Area, Riverside County, California Project No. 10143.003

- 15 -
resulting resistance developed by the soil is the "passive" resistance. Retaining walls backfilled with non-expansive soils should be designed using the following equivalent fluid pressures:

Table 2. Retaining Wall Design Earth Pressures (Static, Drained) Loading
Conditions
Equivalent Fluid Density (pcf)
Level Backfill 2:1 Backfill
Active 35 50
At-Rest 50 80
Passive* 300 150 (2:1, sloping down)
* This assumes level condition in front of the wall will remain for the duration of the project, not to exceed 3,000 psf at depth. If sloping down (2:1) grades exist in front of walls, then they should be designed using passive values reduced to ½ of level backfill passive resistance values.

Unrestrained (yielding) cantilever walls should be designed for the active equivalent-fluid weight value provided above for very low to low expansive soils that are free draining. In the design of walls restrained from movement at the top (non-yielding) such as basement or elevator pit/utility vaults, the at-rest equivalent fluid weight value should be used. Total depth of retained earth for design of cantilever walls should be measured as the vertical distance below the ground surface measured at the wall face for stem design, or measured at the heel of the footing for overturning and sliding calculations. Should a sloping backfill other than a 2:1 (horizontal:vertical) be constructed above the wall (or a backfill is loaded by an adjacent surcharge load), the equivalent fluid weight values provided above should be re-evaluated on an individual case basis by us.

Non-standard wall designs should also be reviewed by us prior to construction to check that the proper soil parameters have been incorporated into the wall design.

All retaining walls should be provided with appropriate drainage. The outlet pipe should be sloped to drain to a suitable outlet. Typical wall drainage design is illustrated in Appendix C , Retaining Wall Backfill and Subdrain Detail . Wall backfill should be non-expansive (EI  21) sands compacted by mechanical methods to a minimum of 90 percent relative compaction (ASTM D 1557).

Clayey site soils should not be used as wall backfill. Walls should not be backfilled until wall concrete attains the 28-day compressive strength and/or as determined by the Structural Engineer that the wall is structurally capable of supporting backfill. Lightweight compaction equipment should be used, unless otherwise approved by the Structural Engineer.

5.5 Geochemical Characteristics
Limited laboratory testing indicated a negligible concentration of soluble sulfates in onsite soils for representative samples. The laboratory test results are presented in Appendix B.

Additional corrosion testing should be performed on representative finish grade soils at the completion of rough grading. Concrete foundations in contact with site soils should be designed in accordance with 2013 CBC . A qualified corrosion engineer should be consulted to review the results of laboratory tests and coordinate additional testing if corrosion sensitive materials are to be used.

5.6 Preliminary Pavement Design Parameters
In order to provide the following recommendations, we have assumed an R-value of 45 based on our laboratory testing and the granular nature of the onsite soils and results of our laboratory testing . For the final pavement design, appropriate traffic indices should be selected by the project civil engineer or traffic engineering consultant and representative samples of actual subgrade materials should be tested for R-value.

The subgrade soils in the upper 6 inches should be properly compacted to at least 95 percent relative compaction (ASTM D1557) and should be moisture- conditioned to near optimum and kept in this condition until the pavement section is constructed. Proof-rolling subgrade to identify localized areas of yielding subgrade (if any) should be performed prior to placement of aggregate base and under the observation of the geotechnical consultant.

Minimum relative compaction requirements for aggregate base should be 95 percent of the maximum laboratory density as determined by ASTM D1557.

Base rock should conform to the "Standard Specifications for Public Works 12-1655

6.0 G E O T E C H N I C A L C O N S T R U C T I O N S E R V I C E S Geotechnical review is of paramount importance in engineering practice. Poor performances of many foundation and earthwork projects have been attributed to inadequate construction review. We recommend that Leighton be provided the opportunity to review the grading plan and foundation plan(s) for each type of structure that design level recommendations can be provided based on actual loads and locations.

Reasonably-continuous construction observation and review during site grading and foundation installation allows for evaluation of the actual soil conditions and the ability to provide appropriate revisions where required during construction. Geotechnical conclusions and preliminary recommendations should be reviewed and verified by Leighton during construction, and revised accordingly if geotechnical conditions encountered vary from our findings and interpretations. Geotechnical observation and testing should be provided:
 After completion of site demolition and clearing,
 During ground preparation, fill slope key excavations, overexcavation of surface soils and subdrain placement as described herein,
 During compaction of all fill materials,
 After excavation of all footings, and prior to placement of concrete,  During utility trench backfilling and compaction, and  When any unusual conditions are encountered.

Additional geotechnical exploration and analysis may be required based on final development plans, for reasons such as significant changes in proposed structure locations/footprints. We should review grading (civil) and foundation (structural) plans, and comment further on geotechnical aspects of this project.

7.0 L I M I T A T I O N S
This report was necessarily based in part upon data obtained from a limited number of observances, site visits, soil samples, tests, analyses, histories of occurrences, spaced subsurface explorations and limited information on historical events and observations.

Such information is necessarily incomplete. The nature of many sites is such that differing characteristics can be experienced within small distances and under various climatic conditions. Changes in subsurface conditions can and do occur over time. This investigation was performed with the understanding that the subject site is proposed for residential and commercial development. The client is referred to Appendix D regarding important information provided by the Associated Soil and Foundation Engineers (ASFE) on geotechnical engineering studies and reports and their applicability.

This report was prepared for Meridian Consultants, LLC., based on its needs, directions, and requirements at the time of our investigation. This report is not authorized for use by, and is not to be relied upon by any party except Meridian consultants, LLC, and its successors and assigns as owner of the property, with whom Leighton and Associates, Inc. has contracted for the work. Use of or reliance on this report by any other party is at that party's risk. Unauthorized use of or reliance on this report constitutes an agreement to defend and indemnify Leighton and Associates, Inc. from and against any liability which may arise as a result of such use or reliance, regardless of any fault, negligence, or strict liability of Leighton and Associates, Inc.

General Earthwork and Grading Specifications
-1-

1.0 General

1.1 Intent

These General Earthwork and Grading Specifications are for the grading and earthwork shown on the approved grading plan(s) and/or indicated in the geotechnical report(s). These Specifications are a part of the recommendations contained in the geotechnical report(s). In case of conflict, the specific recommendations in the geotechnical report shall supersede these more general Specifications. Observations of the earthwork by the project Geotechnical Consultant during the course of grading may result in new or revised recommendations that could supersede these specifications or the recommendations in the geotechnical report(s).

1.2 The Geotechnical Consultant of Record

Prior to commencement of work, the owner shall employ the Geotechnical Consultant of Record (Geotechnical Consultant). The Geotechnical Consultants shall be responsible for reviewing the approved geotechnical report(s) and accepting the adequacy of the preliminary geotechnical findings, conclusions, and recommendations prior to the commencement of the grading.

Prior to commencement of grading, the Geotechnical Consultant shall review the "work plan" prepared by the Earthwork Contractor (Contractor) and schedule sufficient personnel to perform the appropriate level of observation, mapping, and compaction testing.

During the grading and earthwork operations, the Geotechnical Consultant shall observe, map, and document the subsurface exposures to verify the geotechnical design assumptions. If the observed conditions are found to be significantly different than the interpreted assumptions during the design phase, the Geotechnical Consultant shall inform the owner, recommend appropriate changes in design to accommodate the observed conditions, and notify the review agency where required. Subsurface areas to be geotechnically observed, mapped, elevations recorded, and/or tested include natural ground after it has been cleared for receiving fill but before fill is placed, bottoms of all "remedial removal" areas, all key bottoms, and benches made on sloping ground to receive fill.

The Geotechnical Consultant shall observe the moisture-conditioning and processing of the subgrade and fill materials and perform relative compaction testing of fill to determine the attained level of compaction. The Geotechnical Consultant shall provide the test results to the owner and the Contractor on a routine and
frequent basis.

1.3 The Earthwork Contractor

The Earthwork Contractor (Contractor) shall be qualified, experienced, and knowledgeable in earthwork logistics, preparation and processing of ground to receive fill, moisture-conditioning and processing of fill, and compacting fill. The Contractor shall review and accept the plans, geotechnical report(s), and these Specifications prior to commencement of grading. The Contractor shall be solely responsible for performing the grading in accordance with the plans and specifications.

The Contractor shall prepare and submit to the owner and the Geotechnical Consultant a work plan that indicates the sequence of earthwork grading, the number of "spreads" of work and the estimated quantities of daily earthwork contemplated for the site prior to commencement of grading. The Contractor shall inform the owner and the Geotechnical Consultant of changes in work schedules and updates to the work plan at least 24 hours in advance of such chang
es so that appropriate observations and tests can be planned and accomplished. The Contractor shall not assume that the Geotechnical Consultant is aware of all grading operations.

The Contractor shall have the sole responsibility to provide adequate equipment and methods to accomplish the earthwork in accordance with the applicable grading codes and agency ordinances, these Specifications, and the recommendations in the approved geotechnical report(s) and grading plan(s). If, in the opinion of the Geotechnical Consultant, unsatisfactory conditions, such as unsuitable soil, improper moisture condition, inadequate compaction, insufficient buttress key size, adverse weather, etc., are resulting in a quality of work less than required in these specifications, the Geotechnical Consultant shall reject the work and may recommend to the owner that construction be stopped until the conditions are rectified.

2.0 Preparation of Areas to be Filled

2.1 Clearing and Grubbing

Vegetation, such as brush, grass, roots, and other deleterious material shall be sufficiently removed and properly disposed of in a method acceptable to the owner, governing agencies, and the Geotechnical Consultant.

The Geotechnical Consultant shall evaluate the extent of these removals depending on specific site conditions. Earth fill material shall not contain more than 1 percent of organic materials (by volume). No fill lift shall contain more than 5 percent of organic matter. Nesting of the organic materials shall not be allowed.

12-1696
LEIGHTON AND ASSOCIATES, INC.

General Earthwork and Grading Specifications
-3-
If potentially hazardous materials are encountered, the Contractor shall stop work in the affected area, and a hazardous material specialist shall be informed immediately for proper evaluation and handling of these materials prior to continuing to work in that area.

As presently defined by the State of California, most refined petroleum products (gasoline, diesel fuel, motor oil, grease, coolant, etc.) have chemical constituents that are considered to be hazardous waste. As such, the indiscriminate dumping or spillage of these fluids onto the ground may constitute a misdemeanor, punishable by fines and/or imprisonment, and shall not be allowed.

2.2 Processing

Existing ground that has been declared satisfactory for support of fill by the Geotechnical Consultant shall be scarified to a minimum depth of 6 inches.

Existing
ground that is not satisfactory shall be overexcavated as specified in the following section. Scarification shall continue until soils are broken down and free of large clay lumps or clods and the working surface is reasonably uniform, flat, and free of uneven features that would inhibit uniform compaction.

2.3 Overexcavation

In addition to removals and overexcavations recommended in the approved geotechnical report(s) and the grading plan, soft, loose, dry, saturated, spongy, organic-rich, highly fractured or otherwise unsuitable ground shall be overexcavated to competent ground as evaluated by the Geotechnical Consultant during grading.

2.4 Benching

Where fills are to be placed on ground with slopes steeper than 5:1 (horizontal to vertical units), the ground shall be stepped or benched. The lowest bench or key shall be a minimum of 15 feet wide and at least 2 feet deep, into competent material
as evaluated by the Geotechnical Consultant. Other benches shall be excavated a minimum height of 4 feet into competent material or as otherwise recommended by the Geotechnical Consultant. Fill placed on ground sloping flatter than 5:1 shall also be benched or otherwise overexcavated to provide a flat subgrade for the fill.

2.5 Evaluation/Acceptance of Fill Areas

All areas to receive fill, including removal and processed areas, key bottoms, and benches, shall be observed, mapped, elevations recorded, and/or tested prior to being accepted by the Geotechnical Consultant as suitable to receive fill. The Contractor shall obtain a written acceptance from the Geotechnical Consultant 12-1697
LEIGHTON AND ASSOCIATES, INC.

General Earthwork and Grading Specifications
-4-
prior to fill placement. A licensed surveyor shall provide the survey control for determining elevations of processed areas, keys, and benches.

3.0 Fill Material

3.1 General

Material to be used as fill shall be essentially free of organic matter and other deleterious substances evaluated and accepted by the Geotechnical Consultant prior to placement. Soils of poor quality, such as those with unacceptable gradation, high expansion potential, or low strength shall be placed in areas acceptable to the Geotechnical Consultant or mixed with other soils to achieve satisfactory fill material.

3.2 Oversize

Oversize material defined as rock, or other irreducible material with a maximum dimension greater than 8 inches, shall not be buried or placed in fill unless location,
materials, and placement methods are specifically accepted by the Geotechnical Consultant. Placement operations shall be such that nesting of oversized material does not occur and such that oversize material is completely surrounded by compacted or densified fill. Oversize material shall not be placed within 10
vertical feet of finish grade or within 2 feet of future utilities or underground
construction.

3.3 Import

If importing of fill material is required for grading, proposed import material shall meet the requirements of Section 3.1. The potential import source shall be given to the Ge
otechnical Consultant at least 48 hours (2 working days) before importing begins so that its suitability can be determined and appropriate tests performed.

4.0 Fill Placement and Compaction

4.1 Fill Layers

Approved fill material shall be placed in areas prepared to receive fill (per Section

3.0) in near-horizontal layers not exceeding 8 inches in loose thickness.

The Ge
otechnical Consultant may accept thicker layers if testing indicates the grading procedures can adequately compact the thicker layers. Each layer shall be spread evenly and mixed thoroughly to attain relative uniformity of material and moisture throughout.
12-1698
LEIGHTON AND ASSOCIATES, INC.

General Earthwork and Grading Specifications
-5-

4.2 Fill Moisture Conditioning

Fill soils shall be watered, dried back, blended, and/or mixed, as necessary to attain a relatively uniform moisture content at or slightly over optimum.

Maximum density and optimum soil moisture content tests shall be performed in accordance with the American Society of Testing and Materials (ASTM Test Method D1557).

4.3 Compaction of Fill

After each layer has been moisture-conditioned, mixed, and evenly spread, it shall be uniformly compacted to not less than 90 percent of maximum dry density (ASTM Test Method D1557). Compaction equipment shall be adequately sized and be either specifically designed for soil compaction or of proven reliability to efficiently achieve the specified level of compaction with uniformity.

4.4 Compaction of Fill Slopes

In addition to normal compaction procedures specified above, compaction of slopes shall be accomplished by backrolling of slopes with sheepsfoot rollers at increments of 3 to 4 feet in fill elevation, or by other methods producing satisfa
ctory results acceptable to the Geotechnical Consultant. Upon completion of grading, relative compaction of the fill, out to the slope face, shall be at least 90 percent of maximum density per ASTM Test Method D1557.

4.5 Compaction Testing

Field-tests for moisture content and relative compaction of the fill soils shall be performed by the Geotechnical Consultant. Location and frequency of tests shall be at the Consultant's discretion based on field conditions encountered.

Compaction test locations will not necessarily be selected on a random basis. Test locations shall be selected to verify adequacy of compaction levels in areas that are judged to be prone to inadequate compaction (such as close to slope faces and at the fill/bedrock benches).

4.6 Frequency of Compaction Testing

Tests shall be taken at intervals not exceeding 2 feet in vertical rise and/or 1,000 cubic yards of compacted fill soils embankment. In addition, as a guideline, at least one test shall be taken on slope faces for each 5,000 square feet of slope face
and/or each 10 feet of vertical height of slope. The Contractor shall assure that fill c
onstruction is such that the testing schedule can be accomplished by the Geotechnical Consultant. The Contractor shall stop or slow down the earthwork construction if these minimum standards are not met.

12-1699

4.7 Compaction Test Locations

The Geotechnical Consultant shall document the approximate elevation and horizontal coordinates of each test location. The Contractor shall coordinate with the project surveyor to assure that sufficient grade stakes are established so that the Geotechnical Consultant can determine the test locations with sufficient accuracy. At a minimum, two grade stakes within a horizontal distance of 100 feet and vertically less than 5 feet apart from potential test locations shall be provided.

5.0 Subdrain Installation

Subdrain systems shall be installed in accordance with the approved geotechnical report(s), the grading plan. The Geotechnical Consultant may recommend additional subdrains and/or changes in subdrain extent, location, grade, or material depending on conditions encountered during grading. All subdrains shall be surveyed by a land surveyor/civil engineer for line and grade after installation and prior to burial. Sufficient time should be allowed by the Contractor for these surveys.

6.0 Excavation

Excavations, as well as over-excavation for remedial purposes, shall be evaluated by the Geotechnical Consultant during grading. Remedial removal depths shown on geotechnical plans are estimates only. The actual extent of removal shall be determined by the Geotechnical Consultant based on the field evaluation of exposed conditions during grading. Where fill-over-cut slopes are to be graded, the cut portion of the slope shall be made, evaluated, and accepted by the Geotechnical Consultant prior to placement of materials for construction of the fill portion of the slope, unless otherwise recommended by the Geotechnical Consultant.

7.0 Trench Backfills

7.1 Safety

The Contractor shall follow all OSHA and Cal/OSHA requirements for safety of trench excavations.

7.2 Bedding and Backfill

All bedding and backfill of utility trenches shall be performed in accordance with the applicable provisions of Standard Specifications of Public Works Construction. Bedding material shall have a Sand Equivalent greater than 30 (SE>30). The bedding shall be placed to 1 foot over the top of the conduit and densified by jetting. Backfill shall be placed and densified to a minimum of 90 percent of relative compaction from 1 foot above the top of the conduit to the surface.

The Geotechnical Consultant shall test the trench backfill for relative compaction.

At least one test should be made for every 300 feet of trench and 2 feet of fill.

7.3 Lift Thickness

Lift thickness of trench backfill shall not exceed those allowed in the Standard Specifications of Public Works Construction unless the Contractor can demonstrate to the Geotechnical Consultant that the fill lift can be compacted to the minimum relative compaction by his alternative equipment and method.

7.4 Observation and Testing

The jetting of the bedding around the conduits shall be observed by the Geotechnical Consultant.

ASFE Important Information about Your Geotechnical Engineering Report 12-1708
Important Information About Your
Geotechnical Engineering Report
Subsurface problems are a principal cause of construction delays, cost overruns, claims, and disputes.

The following information is provided to help you manage your risks.

Geotechnical Services Are Performed lor
Specific Purposes, Persons, and Projects
Geotechnical engineers structure their services to meet the specific needs of their clients. A geotechnical engineering study conducted for a civil engi neer may not fulfill the needs of a construction contractor or even another civil engineer. Because each geotechnical engineering study is unique, each geotechnical engineering report is unique, prepared solely for the client. No one except you should rely on your geotechnical engineering report without first conferring with the geotechnical engineer who prepared it. And no one -not even you -should apply the report for any purpose or project except the one originally contemplated.

Read the Full Report
Serious problems have occurred because those relying on a geotechnical engineering report did not read it all. Do not rely on an executive summary.

Do not read selected elements only.

A Geotechnical Engineering Report Is Based on
A Unique-Set ol Project-Specific Factors
Geotechnical engineers consider a number of unique, project-specific fac tors when establishing the scope of a study. Typical factors include: the client's goals, objectives, and risk management preferences; the general nature of the structure involved, its size, and configuration; the location of the structure on the site; and other planned or existing site improvements, such as access roads, parking lots, and underground utilities. Unless the geotechnical engineer who conducted the study specifically indicates oth erwise, do not rely on a geotechnical engineering report that was:
• not prepared for you,
• not prepared for your project,
• not prepared for the specific site explored, or
• completed before important project changes were made.

Typical changes that can erode the reliability of an existing geotechnical engineering report include those that affect:
• the function of the proposed structure, as when it's changed from a parking garage to an office building, or from a light industrial plant to a refrigerated warehouse,
• elevation, configuration, location, orientation, or weight of the proposed structure,
• composition of the design team, or
• project ownership.

As a general rule, always inform your geotechnical engineer of project changes-even minor ones-and request an assessment of their impact.

Geotechnical engineers cannot accept responsibility or liability for problems that occur because their reports do not consider developments of which they were not informed.

Subsurface Conditions Can Change
A geotechnical engineering report is based on conditions that existed at the time the study was performed. Do not rely on a geotechnical engineer ing report whose adequacy may have been affected by: the passage of time; by man-made events, such as construction on or adjacent to the site; or by natural events, such as floods, earthquakes, or groundwater fluctua tions. Always contact the geotechnical engineer before applying the report to determine if it is still reliable. A minor amount of additional testing or analysis could prevent major problems.

Most Geotechnical Findings Are Professional
Opinions
Site exploration identifies subsurface conditions only at those points where subsurface tests are conducted or samples are taken. Geotechnical engi neers review field and laboratory data and then apply their professional judgment to render an opinion about subsurface conditions throughout the site. Actual subsurface conditions may differ-sometimes significantly from those indicated in your report. Retaining the geotechnical engineer who developed your report to provide construction observation is the most effective method of managing the risks associated with unanticipated conditions.

A Report's Recommendations Are 11/ot Final
Do not overrely on the construction recommendations included in your report. Those recommendations are not final, because geotechnical engi neers develop them principally from judgment and opinion. Geotechnical engineers can finalize their recommendations only by observing actual 12-1709
subsurface conditions revealed during construction. The geotechnical engineer who developed your report cannot assume responsibility or liability for the report's recommendations if that engineer does not perform construction observation.

A Geotechnical Engineering Report Is Subject to
Misinterpretation
Other design team members' misinterpretation of geotechnical engineering reports has resulted in costly problems. Lower that risk by having your geo technical engineer confer with appropriate members of the design team after submitting the report. Also retain your geotechnical engineer to review perti nent elements of the design team's plans and specifications. Contractors can also misinterpret a geotechnical engineering report. Reduce that risk by having your geotechnical engineer participate in prebid and preconstruction conferences, and by providing construction observation.

Do Not Redraw the Engineer•s Logs
Geotechnical engineers prepare final boring and testing logs based upon their interpretation of field logs and laboratory data. To prevent errors or omissions, the logs included in a geotechnical engineering report should never be redrawn for inclusion in architectural or other design drawings.

Only photographic or electronic reproduction is acceptable, but recognize that separating logs from the report can elevate risk.

Give Contractors a Complete Report and
Guidance
Some owners and design professionals mistakenly believe they can make contractors liable for unanticipated subsurface conditions by limiting what they provide for bid preparation. To help prevent costly problems, give con tractors the complete geotechnical engineering report, but preface it with a clearly written letter of transmittal. In that letter, advise contractors that the report was not prepared for purposes of bid development and that the report's accuracy is limited; encourage them to confer with the geotechnical engineer who prepared the report (a modest fee may be required) and/or to conduct additional study to obtain the specific types of information they need or prefer. A prebid conference can also be valuable. Be sure contrac tors have sufficient time to perform additional study. Only then might you be in a position to give contractors the best information available to you, while requiring them to at least share some of the financial responsibilities stemming from unanticipated conditions.

Read Responsibility Provisions Closely
Some clients, design professionals, and contractors do not recognize that geotechnical engineering is far less exact than other engineering disci plines. This lack of understanding has created unrealistic expectations that have led to disappointments, claims, and disputes. To help reduce the risk of such outcomes, geotechnical engineers commonly include a variety of explanatory provisions in their reports. Sometimes labeled "limitations" many of these provisions indicate where geotechnical engineers' responsi bilities begin and end, to help others recognize their own responsibilities and risks. Read these provisions closely Ask questions. Your geotechnical engineer should respond fully and frankly.

Geoenvironmental Concerns Are Not Covered
The equipment, techniques, and personnel used to perform a geoenviron mental study differ significantly from those used to perform a geotechnical study. For that reason, a geotechnical engineering report does not usually relate any geoenvironmental findings, conclusions, or recommendations; e.g., about the likelihood of encountering underground storage tanks or regulated contaminants. Unanticipated environmental problems have led to numerous project failures. If you have not yet obtained your own geoen vironmental information, ask your geotechnical consultant for risk man agement guidance. Do not rely on an environmental report prepared for someone else.

Obtain Professional Assistance To Deal with Mold
Diverse strategies can be applied during building design, construction, operation, and maintenance to prevent significant amounts of mold from growing on indoor surfaces. To be effective, all such strategies should be devised for the express purpose of mold prevention, integrated into a com prehensive plan, and executed with diligent oversight by a professional mold prevention consultant. Because just a small amount of water or moisture can lead to the development of severe mold infestations, a num ber of mold prevention strategies focus on keeping building surfaces dry.

While groundwater, water infiltration, and similar issues may have been addressed as part of the geotechnical engineering study whose findings are conveyed in this report, the geotechnical engineer in charge of this project is not a mold prevention consultant; none of the services per formed in connection with the geotechnical engineer's study were designed or conducted for the purpose of mold preven tion. Proper implementation of the recommendations conveyed in this report will not of itself be sufficient to prevent mold from growing in or on the structure involved.

Subject: Phase I and Limited Phase II ESA Addendum Letter Rancho Mirage 1200
Assessor Parcel Numbers 673-120-021 through -025
Rancho Mirage, Unincorporated Area of Riverside County, California

Leighton and Associates, Inc. (Leighton) presents this Addendum to the Phase I and Phase II Environmental Site Assessment (ESA) prepared for the subject site in 2013 (Leighton, 2013). The purpose of this Phase I ESA Addendum is to incorporate the additional property (Assessor Parcel Numbers [APNs] 673- 120-021 and 673- 120-022) that are now associated with the subject site (see Figure 1 – Site Location Map). The scope of work for this Phase I ESA Addendum Letter included: an updated review of historical aerial photographs and topographic maps (to include the new APNs) , review of an online database resources such as Geotracker and Envirostor , a site reconnaissance, and preparation of this addendum letter.

SITE RECONNAISSANCE
On June 20, 2014, Leighton personnel conducted a reconnaissance-level visit of the subject site to observe and document existing site conditions. The two new APNs consist of approximately 72 acres of vacant land. The eastern half of the northeastern parcel (APN 673-120-022) appears to have been paved with asphalt and possibly used as a construction staging/parking or overflow parking lot for the casino (based on aerial photographs). The entrance to this paved area is now blocked and the asphalt is degraded and covered in windblown sand. Small areas of asphalt and construction debris were observed in the middle portion of the northeastern parcel separating the pav
ed area from the vacant land. A stormwater retention basin was observed in the northwestern portion of this parcel. The southeastern parcel was observed to be a 12-1712
10143.001
- 3 -
vacant land, with the exception of a pole mounted billboard in the corner of the parcel, and a small stockpile of aggregate base and asphalt debris on the eastern border of the subject parcel (APN 673-120-021). Significant changes were not observed on the original parcels, with the exception of more blown sand on the eastern and southern borders of the subject site.

ONLINE DATABASE RESOURCES
A search of the selected online government databases was conducted by Leighton on June 19, 2014. A review of The Department of Toxic Substances Control ’s (DTSC) website Envirostor and the State Water Resources Control Board’s (SWRCB) online database GeoTracker did not reveal any environmental sites of concern within one mile of the of the subject site.

REVIEW OF HISTORICAL AERIAL PHOTOGRAPHS
Historical aerial photographs were reviewed for information regarding past subject site uses. Aerial photographs dated 1953, 1969, 1978, 1984, 1989, 2002, 2005, 2007, 2009, and 2010 were reviewed.

In the 1953 aerial photograph, the subject site and adjacent properties are vacant, undeveloped land. Paved Ramon Road and Bob Hope Drive are observed to the north and the east of the subject site, respectively. Southern Pacific railroad is observed approximately 650 feet to the northeast of the subject site.

Significant changes were not observed in the 1969, 1978 and 1984 aerial photographs, with the exception of the addition of Interstate 10 (northeast of the railroad) and its on- ramps and off-ramps located to the northeast of the subject site, and what appears to be part of Dinah Shore Drive to the southeast of the subject site.

In the 1989 aerial photograph, the subject site and adjacent properties to the north and east are observed to be vacant, undeveloped land. Paved Dinah Shore Drive and additional residential development are depicted to the south of the subject site, and a golf course was observed to the west of the subject site. Los Alamos Road is a dirt road.

In the 2002 aerial photograph, the subject site and adjacent properties to the north and east are observed to be vacant, undeveloped land. Adjacent properties to the west and south of the subject site were observed to be in development as the present day 12-1713
10143.001
- 4 -
residential homes and golf courses. Adjacent to the northeast was observed the original Agua Caliente Casino and Resort. Los Alamos Road is a paved road.

In the 2005 aerial photograph, significant changes were not observed on the subject site and adjacent properties.

In a 2007 aerial photograph viewed on the Riverside County Land Information System (RCLIS) website for APN 673- 120-022, it appears that the northeastern section of the subject site appears to have graded and used for staging construction materials, equipment, vehicles, and modular offices (RCLIS, 2014). There is what appears to be a depression in the northeast corner of the staging area. Construction activiti es for the Agua Caliente Casino and Resort were observed in the adjacent property to northeast of the subject site. Significant changes were not observed on the adjacent properties.

In the 2009 aerial photograph it appears that the construction activiti es for the Agua Caliente Casino and Resort have ceased and the graded area appears to be vacant .

Significant changes were not observed on the majority of the subject site and adjacent properties.

In the 2010 aerial photograph, the subject site and adjacent properties appear in the present day configuration.

REVIEW OF HISTORICAL TOPOGRAPHIC MAPS
Historical topographic maps were reviewed to obtain information regarding past site uses. Topographic map coverage of the site vicinity is provided by “Indio, California” Quadrangle (1904) and “Edom, California” Quadrangle (1941), “Thousand Palms, California” Quadrangle (1947, and 1958), and “Cathedral City, California” Quadrangle (1958, 1972, and 1981). References are provided in Appendix A.

Indio 1904: Structures, tanks, or wells were not depicted on the subject site or adjacent properties.

Edom 1941 : Structures, tanks, or wells were not depicted on the subject site or adjacent properties. Southern Pacific railroad is observed approximately 650 feet to the northeast of the subject site.

12-1714
10143.001
- 5 -
Thousand Palms 1947 : Land use changes were not depicted on the subject site or adjacent properties.

Thousand Palms 1958 : Land use changes were not depicted on the subject site or adjacent properties. Ramon Road is observed to the north of the subject site, and Rio Del Sol (present day Bob Hope Drive) is observed to the east of the subject site.

Cathedral City 1958 : Land use changes were not depicted on the subject site or adjacent properties, with the exception of some residential development to the southeast of the subject site.

Cathedral City 1972 : Land use changes were not depicted on the subject site or adjacent properties.

Cathedral City 1981 : Land use changes were not depicted on the subject site or adjacent properties.

CONCLUSIONS AND RECOMMENDATIONS
Historically, the subject site has been vacant, undeveloped land. Portions of the subject site have been graded, used for construction staging, and possibly offsite casino parking.

Based on our review of information on the subject site and the addition of the two APNs, there are no changes to the conclusions and recommendations of the Phase I and Phase II ESA.

We have performed a Phase I and Limited Phase II ESA in conformance with the scope and limitations of ASTM E1527-05 on of the Rancho Mirage 1200 Property, APNs 673- 120-021 through -025, Rancho Mirage, an Unincorporated Area of Riverside County, California, the property. Exceptions to, or deletions from, this practice are described in Section 1.5 of this report. This assessment has revealed no evidence of recognized environmental conditions in connection with the property.

In general, observations should be made during future site development for areas of possible contamination such as, but not limited to, the presence of underground facilities, buried debris, waste drums, and tanks, stained soil or odorous soils. Should 12-1715

such materials be encountered, further investigation and analysis may be necessary at that time.

If you have questions regarding this report, please contact us. We appreciate the opportunity to be of service to Pulte Homes.

1.0 INTRODUCTION

1.1 Authorization
Leighton and Associates, Inc. (Leighton) performed a Phase I and Limited Phase II Environmental Site Assessment (ESA) for the Rancho Mirage 1200 Property, Assessor Parcel Numbers (APNs) 673-120-023, -024, and -025, Rancho Mirage, an Unincorporated Area of Riverside County, California (subject site – Figure 1) in accordance with the authorization of Pulte Home Corporation.

1.2 Purpose
The purpose of the Phase I and Limited Phase II ESA was to identify, to the extent feasible pursuant to the processes prescribed in ASTM International (ASTM) Standard E1527-0 5, recognized environmental conditions (RECs) in connection with the subject site. Recognized environmental conditions are defined as “the presence or likely presence of any hazardous substances or petroleum products on a property under conditions that indicate an existing release, a past release, or a material threat of a release of any hazardous substances or petroleum products into structures on the property or into the ground, groundwater, or surface water of the property. The term includes hazardous substances or petroleum products even under conditions in compliance with laws. The term is not intended to include de minimus conditions that generally do not present a threat to human health or the environment and that generally would not be the subject of an enforcement action if brought to the attention of appropriate governmental agencies. Conditions determined to be de minimus are not recognized environmental conditions” (ASTM E1527-05, 2005).

1.3 Scope of Work
The scope of work was performed in accordance with Leighton’s proposal and included the following tasks:


A reconnaissance-level visit of the subject site for evidence of the release(s) of hazardous materials and petroleum products and to assess the potential for onsite releases of hazardous materials and petroleum products;  Records review (including review of previous environmental reports, selected governmental databases, and historical review);
 Interviews;
12-1725
10143.001
- 2 -
 Limited soil sampling; and
 Preparation of a report presenting our findings.

1.4 Significant Assumptions
Leighton assumes that the information provided by the Client and its agents, regulatory database provider, and regulatory agencies is true and reliable.

1.5 Limitations and Exceptions
Leighton performed the Phase I and Phase II Limited ESA in conformance with the scope and limitations of ASTM Practice E1527- 05 of the subject site. Other than the non-scope items shown in Section 1.6 that were not applicable, there were no exceptions to, or deletions from, this practice.

Prop
erty-specific activities performed by Leighton and information collected regarding these activities are summarized within this report. The findings of this Phase I and Limited Phase II ESA are presented in Section 8.0. Opinions and conclusions drawn by Leighton, based on the information collected as part of the Phase I and Limited Phase II ESA, are presented in Sections 9.0 and 10.0, respectively. References are included as Appendix A. Site Photographs are presented in Appendix B. Client Supplied documentation is included as Appendix C. Research of Environmental Liens is documented in Appendix D.

The Environmental Radius Report is included as Appendix E. Regulatory records requests and responses are included as Appendix F. Historical documentation is provided in Appendix G. Laboratory reports are provided in Appendix H.

This Phase I and Limited Phase II ESA was conducted in a manner consistent with the level of care and skill ordinarily exercised by members of the profession currently practicing in the same locality under similar conditions.

The observations and conclusions presented in this report are professional opinions based on the scope of activities, work schedule, and information obtained through the Phase I and Limited Phase II ESA described herein.

Opinions presented herein apply to property conditions existing at the time of our study and cannot necessarily be taken to apply to property conditions or changes that we are not aware of or have not had the opportunity to evaluate. It must be recognized that conclusions drawn from these data are limited to the amount, 12-1726
10143.001

type, distribution, and integrity of the information collected at the time of the investigation, the methods utilized to collect and evaluate the data, and that a full and complete determination of environmental risks cannot be made. Although Leighton has taken steps to obtain true copies of available information, we make no representation or warranty with respect to the accuracy or completeness of this information.

This practice does not address whether requirements in addition to all appropriate inquiry have been met in order to qualify for the landowner liability protections including the continuing obligation not to impede the integrity and effectiveness of activity and use limitations, or the duty to take reasonable steps to prevent releases, or the duty to comply with legally required release reporting obligations. Users should also be aware that there are likely to be other legal obligations with regard to hazardous substances or petroleum products discovered on the subject site that are not addressed in this practice and that may pose risks of civil and/or criminal sanctions for non-compliance.

1.6 Special Terms and Conditions
The scope of work for this Phase I and Limited Phase II did not include non- scope considerations, such as, but not limited to, those listed in Section 13 of ASTM E1527-05. This scope of work did not include items such as testing of electrical equipment for the presence of polychlorinated biphenyls (PCBs) or c
ollection of other environmental samples, such as, water, air, building materials, paint or other media; assessment of natural hazards such as naturally occurring asbestos, radon gas, methane gas, or mold; assessment of the potential presence of radionuclides, biological agents, or lead in drinking water; assessment of indoor air quality (such as vapor intrusion assessment); or assessment of nonchemical hazards such as the potential for damage from earthquakes or floods, or the presence of endangered species or wildlife habitats. This Phase I and Limited Phase II also did not include an extensive assessment of the environmental compliance status of the Subject Property or of businesses operating at the Subject Property, or a health-based risk assessment.

4.0 RECORDS REVIEW

4.1 Physical Setting Source(s)
Leighton reviewed pertinent maps and readily available literature for information on the physiography and hydrogeology of the subject site. A summary of this information is presented in the following subsections.

4.1.1 Topography
The subject site is located in Section 24 of Township 4 South, Range 5 east of the San Bernardino Baseline and Meridian. Topographic map coverage of the site vicinity is provided by the United States Geological Survey (USGS) “Cathedral City , California” Quadrangle ( 1981). The elevation of the property is approximately 240 to 360 feet above mean sea level and slopes to the southwest and northeast from the central portion of the subject site.

4.1.2 Surface Water
Surface water was not observed on the subject site.

4.1.3 Geology and Soils
According to the Geotechnical Investigation (Leighton, 20 13), the subject site is underlain by Dune Sand over Quaternary Alluvium. Dune sand materials are expected to mantle the majority of the subject site. The depth of the dune sand materials cannot be easily verified based on the limited geotechnical investigation and relatively homogenous onsite alluvium. It is estimated that the dune sands generally extend to a depth varying from 5 to 20 feet below ground surface (bgs). These materials generally consist of light brown gray to darker gray and loose to medium dense silty sand to poorly-graded fine sand. Quaternary-aged alluvial deposits were encountered in all of the borings to the maximum depth explored (51 feet bgs). As encountered, the alluvium typically consists of light brown to brownish gray, medium dense to very dense, poorly-graded fine sand to sand with silt.

4.1.4 Hyd rogeology
The subject site is located in the Colorado River Basin. Beneficial uses of groundwater included municipal or domestic supply, agricultural supply , industrial service supply, and industrial process supply (Colorado River Water Quality Plan, 2006).

According to Well 04S05E29A001S, dated April 1, 1968 (Water Data Library, 1968), located on the property adjacent to the site, groundwater depth is about 173 feet bgs.

Direction of groundwater flow is not known; however it is generally known to follow topography.

4.1.5 Oil and Gas Fields
Leighton and Associates reviewed the California Department of Conservation, Division of Oil, Gas, and Geothermal Resources, Online Mapping System, updated July 23, 2012. Evidence of oil wells or oil field- related facilities was not indicated on the subject site or adjacent properties.

4.2 Standard Environmental Record Sources
A search of selected government databases was conducted by Leighton using the Environmental EDR Radius Report environmental database report system. Details and descriptions of the database search are provided in the EDR report. The report meets the government records search requirements of ASTM E1527-05 Standard Practice for Environmental Property Assessments: Phase I Environmental Property Assessment Process. The database listings were reviewed within the specified radii established by the ASTM E1527-05. A copy of this report is included in Appendix E.

4.2.1 Subject Property
The subject site was identified in the EDR database report as an INDIAN RESERVATION, part of the Agua Caliente Indian Reservation.

12-1733
10143.001
- 10 -

4.2.2 Offsite
Seven facilities were listed on the HAZNET listings:

 Westin Mission Hills Resort , 70705 Ramon Road, Rancho Mirage , located adjacent to the west of the subject site;
 Agua Caliente Band of Cahuilla, 32250 Bob Hope Drive, Rancho Mirage, located adjacent to the northeast of the subject site;  Westin Mission Hills Resort , 71501 Dinah Shore Drive, Rancho Mirage, adjacent to the west of the subject site; and
 Westin Mission Hills Resort , 71333 Dinah Shore Drive, Rancho Mirage, located adjacent to the west of the subject site.

These facilities were listed for waste disposal and mixing categories and violations or enforcements were not noted; therefore there is a low potential for these facilities to adversely affect the subject site.

The MACCO CONSTRUCTORS, INC., 34200 Rio Del Sol, Thousand Palms, was listed on the SWEEPS and UST listings, and is mapped by EDR 0.02 miles east- southeast of the subject site. Based on the site reconnaissance, this property is located 0.50 miles to the northeast of the subject site. Violations or enforcements were not noted on this facility, therefore there is a low potential for this facility to adversely affect the subject site.

Mission Hills Country Club, 34600 Mission Hills Drive, Rancho Mirage, was listed on the INDIAN and LUST listings, and is located 0.42 miles west- southwest of the subject site. Based on the EDR report, this facility was issued case closure. According to the State Water Resources Control Board (SWRCB) online Geotracker database the facility was issued closure on October 7, 2010. Based on the case closure status, there is a low potential for this facility to adversely affect the subject site.

Flying J Travel Plaza, 72235 Varner Road, Thousand Palms, was listed on the LUST listing, and is located 0.46 miles northeast of the subject site.

Based on the EDR report, this facility was issued case closure. According to the SWRCB online Geotracker database the facility was issued closure on October 10, 2003. Based on the case closure status, there is a low potential for this facility to adversely affect the subject site. 12-1734
10143.001
- 11 -

Unmapped Listings: Several properties were listed within Environmental EDR Report as “non -geocoded listings”. Non -geocoded or unmapped listings are properties without a complete street address and therefore cannot be located on a map. Leighton reviewed these listings to evaluate if the properties were possibly located near the subject site. Based on information provided in the Environmental EDR Report and area reconnaissance, these unmapped sites are unlikely to have the potential to adversely impact the subject site.

4.2.3 Regulatory Agency Contacts
On February 7, 2013, Leighton requested regulatory records from the following agencies for the APNs 673- 120-021, 673-120-022, 673-120-023, 673-120-024, and 673-120-025. It should be noted that the subject site does not have a physical address; therefore, the APNs and a Thomas Guide Map were utilized. It is Leighton’ experience that records often cannot be found without a site address.
 Department of Toxic Substances Control (DTSC) – Cypress and Chatsworth Divisions;
 National Pipeline Mapping System (NPMS);
 Regional Water Quality Control Board, Colorado River Region (RWQCB);
 Riverside County Department of Environmental Health (RCDEH) ; and
 South Coast Air Quality Management District (SCAQMD)

Records were not found at the agencies contacted. Copies of records requests and responses are provided in Appendix F.

4.2.4 Other Reports
Additional reports were not provided to Leighton for review.

4.3 Historical Use Information on the Property
Leighton reviewed selected historical information on the subject site. These references were reviewed for evidence of activities, which would suggest the presence of hazardous substances at the subject site and to evaluate the 12-1735
10143.001
- 12 -
potential for the subject site to be impacted by offsite sources of contamination.

The following paragraphs are a chronological summary of the review.

4.3.1 Aerial Photographs
Historical aerial photographs were reviewed for information regarding past subject site uses. Aerial photographs dated 1953, 1969, 1978, 1984, 1989, 2002, 2005, 2009, and 20 10 were reviewed. References are provided in Appendix A.

Southern Pacific railroad is observed approximately 900 feet to the northeast of the subject site.

Significant changes were not observed in the 1969 and 1978 aerial photographs, with the exception of the addition of Interstate 10 (northeast of the railroad) and its on-ramps and off-ramps to the northeast of the subject site, and what appears to be part of Dinah Shore Drive to the southeast of the subject site.

In the 1984 aerial photograph, the subject site remains vacant, undeveloped land. A golf course and residential development is observed south of the subject site.

Adjacent to the northeast was observed the Agua Caliente Casino and Resort. Los Alamos Road is a paved road.

7.0 LIMITED PHASE II ESA

Leighton conducted a Limited Phase II ESA on the property based on the findings of site use identified during this Phase I ESA. Soil stockpiles of unknown sources were identified on the western portion of the subject site. The volume of the soil piles is estimated to be 7,800 cubic yards.

On March 12, 2013, a Leighton representative collected 15 representative soil samples from the five homogeneous soil stockpiles. The 15 soil samples were composited in the laboratory into five composite samples. Soil samples G-1-0.5, G-2-0.5, G-3-0.5, G-4-0.5, and G-5-0.5 were composited into sample C-1. Soil samples G-6-0.5 and G-7-0.5 were composited into sample C-2. Soil samples G-8-0.5, G-9-0.5, and G- 10-0.5 were composited into sample C-3. Soil samples G- 11-0.5, G- 12-0.5, and G- 13-0.5 were composited into sample C-4. Soil samples G- 14-0.5 and G-15-0.5 were composited into sample C-5 (see Figure 2). Freshly exposed soils were excavated from each sample location by removing the surficial 6- to 12-inches of soil and retrieving the sample from depth. Samples were collected in new laboratory supplied 4-ounce glass jars with Teflon- lined lids. The soil samples were labeled with sample identification, date, and time of collection and placed in an ice-chilled cooler and transported under chain- of-custody procedures to Enviro-Chem, Inc. in Pomona, California for analysis.

Each of the composite soil samples were analyzed for total petroleum hydrocarbons (TPH) full carbon chain by EPA Method 8015M, organochlorine pesticides (OCPs) and PCBs by EPA Method 8081A/8082 , Title 22 metals by EPA Method 6010B and 7471A , volatile organic compounds (VOCs) by EPA Method 8260B, and semi-volatile organic compounds (SVOCs) by EPA Method 8270C.

Concentrations of TPH, OCPs, PCBs, VOCs, and SVOCs were not reported above the laboratory reporting limits in each of the composite samples analyzed.

Title 22 Metals were detected below their respective EPA Region 9 Regional Screening Levels for residential property (RSL-R) and California Human Health Screening Level for residential property (CHHSL-R) with the exception of arsenic. Arsenic was detected in four of the five composite samples analyzed at concentrations ranging from 0.290 milligrams per kilogram (mg/kg) to 0.627 mg/kg, well below the Department of Toxic Substances Control (DTSC) established background level of 12 mg/kg (DTSC, 2008).

Concentrations of chemicals of potential concern were not identified exceeding the RSLs or CHHSLs for unrestricted land use in the soil stockpiles.

8.0 FINDINGS

Leighton and Associates, Inc. (Leighton) performed a Phase I and Limited Phase II ESA of the Rancho Mirage 1200 Property, Assessor Parcel Numbers (APNs) 673-120-023, -024, and -025, Unincorporated Area of Riverside County, California in accordance with Pulte Home Corporation’s authorization.

8.1 Onsite
Historically, the subject site has been vacant, undeveloped land. The subject site consists of approximately 488 acres of vacant land (Photos 1 through 8, Appendix B). Undocumented soil stockpiles were noted onsite in the western portion of the subject site. Sources for the large soil stockpile and soils placed on the southwestern portion of the site are unknown. Soil sampling activities of these soil stockpiles indicated that chemicals of potential concern were not identified.

A PVC riser (Photo 7, Appendix B) was observed in the south portion of the subject site. The purpose of this PVC riser could not be determined.

A search of selected government databases was conducted by Leighton using the EDR Radius Report environmental database report system. Details of the database search along with descriptions of each database researched are provided in the EDR report. The report meets the government records search requirements of ASTM E1527-05 Standard Practice for Environmental Property Assessments: Phase I and Limited Phase II Environmental Property Assessment Process. The database listings were reviewed within the specified radii established by the ASTM E1527-05. The subject site was listed in the database report as being a part of the Agua Caliente Indian Reservation.

8.2 Offsite
Historically, the adjacent properties were vacant, undeveloped land. The subject site is currently bordered by Los Alamos Road, a golf course and single family residential homes to the west; Dinah Shore Drive, a golf course and single family residential homes to the south; Ramon Road and vacant land to the north; and Bob Hope Drive, vacant land and Agua Caliente Casino to the east.

Surrounding properties with environmental concern were not identified on the EDR report.

8.3 Data Gaps
Data gaps were identified by Leighton:


Historical records prior to 1909 were not available. It is Leighton’s opinion that this data gap is not significant to identifying recognized environmental conditions on the subject site.

A response from the RCDEH has not been received as of the date of this report. Leighton will forward any received response altering the conclusions and recommendations of this report in an addendum letter. It is Leighton’s opinion that this data gap is not significant to identifying recognized environmental conditions on the subject site. 12-1745

9.0 OPINION

9.1 Onsite
It is Leighton’s opinion that the soil stockpiles are suitable for reuse on the subject site. Construction debris should be disposed of in accordance with regulatory guidelines.

Leighton recommends caution when grading in the area of the PVC riser. If it is determined that the riser leads to an underground storage area or is indicative of hazardous materials or wastes, additional investigation may be recommended in this area.

9.2 Offsite
No offsite recognized environmental conditions were identified that would negatively impact the subject site.

10.0 CONCLUSIONS

We have performed a Phase I and Limited Phase II ESA in conformance with the scope and limitations of ASTM E1527- 05 on of the Rancho Mirage 1200 Property, APNs 673- 120-023, -024, and -025, Rancho Mirage, an Unincorporated Area of Riverside County, California, the property. Exceptions to, or deletions from, this practice are described in Section 1.5 of this report. This assessment has revealed no evidence of recognized environmental conditions in connection with the property.

In general, observations should be made during future property development for areas of possible contamination such as, but not limited to, the presence of underground facilities, buried debris, waste drums, and tanks, stained soil or odorous soils. Should such materials be encountered, further investigation and analysis may be necessary at that time.

NPL: NPL National Priorities List (Superfund). The NPL is a subset of CERCLIS and identifies over 1,200 sites for priority cleanup under the Superfund Program. NPL sites may encompass relatively large areas. As such, EDR provides polygon coverage for over 1,000 NPL site boundaries produced by EPA’s Environmental Photographic Interpretation Center (EPIC) and regional EPA offices. NPL - National Priority List Proposed NPL - Proposed National Priority List Sites.

NPL Delisted: DELISTED NPL The National Oil and Hazardous Substances Pollution Contingency Plan (NCP) establishes the criteria that the EPA uses to delete sites from the NPL. In accordance with 40 CFR 300.425.(e), sites may be deleted from the NPL where no further response is appropriate. DELISTED NPL - National Priority List Deletions CERCLIS: CERCLIS CERCLIS contains data on potentially hazardous waste sites that have been reported to the USEPA by states, municipalities, private companies and private persons, pursuant to Section 103 of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). CERCLIS contains sites which are either proposed to or on the National Priorities List (NPL) and sites which are in the screening and assessment phase for possible inclusion on the NPL. CERCLIS - Comprehensive Environmental Response, Compensation, and Liability Information System
NFRAP: CERCLIS-NFRAP Archived sites are sites that have been removed and archived from the inventory of CERCLIS sites. Archived status indicates that, to the best of EPA’s knowledge, assessment at a site has been completed and that EPA has determined no further steps will be taken to list this site on the National Priorities List (NPL), unless information indicates this decision was not appropriate or other considerations require a recommendation for listing at a later time. This decision does not necessarily mean that there is no hazard associated with a given site; it only means that, based upon available information, the location is not judged to be a potential NPL site. CERCLIS-NFRAP - CERCLIS No Further Remedial Action Planned RCRA COR ACT: CORRACTS CORRACTS identifies hazardous waste handlers with RCRA corrective action activity. CORRACTS - Corrective Action Report
RCRA TSD: RCRA-TSDF RCRAInfo is EPA’s comprehensive information system, providing access to data supporting the Resource Conservation and Recovery Act (RCRA) of 1976 and the Hazardous and Solid Waste Amendments (HSWA) of 1984. The database includes selective information on sites which generate, transport, store, treat and/or dispose of hazardous waste as defined by the Resource Conservation and Recovery Act (RCRA). Transporters are individuals or entities that move hazardous waste from the generator offsite to a facility that can recycle, treat, store, or dispose of the waste. TSDFs treat, store, or dispose of the waste. RCRA-TSDF - RCRA - Treatment, Storage and Disposal
RCRA GEN: RCRA-LQG RCRAInfo is EPA’s comprehensive information system, providing access to data supporting the Resource Conservation and Recovery Act (RCRA) of 1976 and the Hazardous and Solid Waste Amendments (HSWA) of 1984. The database includes selective information on sites which generate, transport, store, treat and/or dispose of hazardous waste as defined by the Resource Conservation and Recovery Act (RCRA). Large quantity generators (LQGs) generate over 1,000 kilograms (kg) of hazardous waste, or over 1 kg of acutely hazardous waste per month. RCRA-LQG - RCRA - Large Quantity Generators RCRA-SQG - RCRA - Small Quantity Generators. RCRA-CESQG - RCRA - Conditionally Exempt Small Quantity Generators.

State/Tribal NPL: RESPONSE Identifies confirmed release sites where DTSC is involved in remediation, either in a lead or oversight capacity. These confirmed release sites are generally high-priority and high potential risk.

RESPONSE - State Response Sites
State/Tribal CERCLIS: ENVIROSTOR The Department of Toxic Substances Control’s (DTSC’s) Site Mitigation and Brownfields Reuse Program’s (SMBRP’s) EnviroStor database identifes sites that have known contamination or sites for which there may be reasons to investigate further. The database includes the following site types: Federal Superfund sites (National Priorities List (NPL)); State Response, including Military Facilities and State Superfund; Voluntary Cleanup; and School sites. EnviroStor provides similar information to the information that was available in CalSites, and provides additional site information, including, but not limited to, identification of formerly-contaminated properties that have been released for reuse, properties where environmental deed restrictions have been recorded to prevent inappropriate land uses, and risk characterization information that is used to assess potential impacts to public health and the environment at contaminated sites. ENVIROSTOR - EnviroStor Database State/Tribal SWL: SWF/LF (SWIS) Active, Closed and Inactive Landfills. SWF/LF records typically contain an inve ntory of solid waste disposal facilities or landfills. These may be active or i nactive facilities or open dumps that failed to meet RCRA Section 4004 criteria for solid waste landfills or disposal sites. SWF/LF (SWIS) - Solid Waste Information System

US Brownfields: US BROWNFIELDS Brownfields are real property, the expansion, redevelopment, or reuse of which may be complicated by the presence or potential presence of a hazardous substance, pollutant, or contaminant.

Cleaning up and reinvesting in these properties takes development pressures off of undeveloped, open land, and both improves and protects the environment. Assessment, Cleanup and Redevelopment Exchange System (ACRES) stores information reported by EPA Brownfields grant recipients on brownfields properties assessed or cleaned up with grant funding as well as information on Targeted Brownfields Assessments performed by EPA Regions. A listing of ACRES Brownfield sites is obtained from Cleanups in My Community.

Local Land Records: DEED Site Mitigation and Brownfields Reuse Program Facility Sites with Deed Restrictions & Hazardous Waste Management Program Facility Sites with Deed / Land Use Restriction. The DTSC Site Mitigation and Brownfields Reuse Program (SMBRP) list includes sites cleaned up under the program’s oversight and generally does not include current or former hazardous waste facilities that required a hazardous waste facility permit.

The list represents deed restrictions that are active. Some sites have multiple deed restrictions. The DTSC Hazardous Waste Management Program (HWMP) has developed a list of current or former hazardous waste facilities that have a recorded land use restriction at the local county recorder’s office. The land use restrictions on this list were required by the DTSC HWMP as a result of the presence of hazardous substances that remain on site after the facility (or part of the facility) has been closed or cleaned up. The types of land use restriction include deed notice, deed restriction, or a land use restriction that binds current and future owners. DEED - Deed Restriction Listing

adjacent siles. Recognize, too, that even some conditions in iesied areas may go undiscovered, because lhe tests or analytical methods used were designed to detect only those conditions assumed to exist.

Manage your risks by retaining your geoenvironmental professional to work with you as the project proceeds. Establish a contingency fund or other means to enable your geoenvironmental professional to respond rapidly, in order to limit the impact of unforeseen conditions.

And to help prevent any misunderstanding, identify those empowered to authorize changes and the administrative procedures that should be followed.
lo No1 Permit Any Other Party To Rely on Le Report
Geoenvironmental professionals design their studies and prepare their reports to meet the specific needs of the clients who retain them, in light of the risk management methods that the client and geoenvi- ronmental professional agree to, and the statutory, regulatory, or other requirements that apply. i'he study designed for a developer may dit- fer sharply from one designed for a lender, insurer, public agency ... or even another developer. Unless the reporf specifically states other- wise, it was developed foryouand onlyyou. Do not unilaterally per- mit any other party to rely on it. The report and the study underlying it may not be adequate for another party's needs, and you could be held liable for shortcomings your geoenvironmental professional was pow- erless to prevent or anticipate, Inform your geoenvironmental profes- sional when you know or expect that someorle else-a third-parly- will want to use or rely on the report. Do notpermit third-pa/tyuse or reliance un!il you first confer with the geoenvironmental professional who prepared the report. Additional testing, analysis, or study may be required and, in any event, appropriate terms and conditions should be agreed to so both you and your geoenvironmental professional are protected from th ird-party risks. Any party who relies on a geoenvi- ronmental report without !he express written permission of the pro- fessional who prepared it and the client for whom it was prepared may be solely liable for any problems that arise.

Avoid Mi-on ol the Report
Design professionals and other parties may want to rely on the report in developing plans and specifications. They need to be advised, in writing, that their needs may not have been considered when the study's scope was developed, and, even if their needs were consid- ered, they might misinterpret geoenvironmental findings, conctu- sions, and recommendations. Commission your geoenvironmenfal professional to explain pertinent elements of the report to others who are permitted to rely on it, arjd to review any plans, specifications or other inslruments of professional service that incorporate any of the repod5 findings, conclusions, or recommendations. Your geoenviron- mental professional has the best understanding of the issues involved, including the fundamental assumptions that underpinned the study's scope.

Ghre Conlraclors Access to Ihe Rqert
Reduce the risk ot delays, claims, and disputes by giving contractors access to the full report, providing !hat it is accompanied by a letter of transmittal that can protect you by making it unquestionably clear that: 1) the study was not conducted and the report was not prepared for purposes of bid development, and 2) the findings, conclusions, and recommendations included in the report are based on a variety of opinions, inferences, and assumptions and are subject to interpreta- tion. Use the letter to also advise contractors to consult with your geoenvironmental professional to obtain clarifications, interpretations, and guidance (a fee may be required for this service), and that-in any event-they should conduct additional studies to obtain the spe- cific type and extent of information each prefers for preparing a bid or cost estimate. Providing access to the full report, with the appropri- ate caveats, helps prevent formation ot adversarial attitudes and claims of concealed or differing conditions. If a contractor elects to ignore the warnings and advice in the letter of transmittal, it would do so at its own risk. Your geoenvironmental professional should be able to help you prepare an effective letter.

OD Nol Separate Documenlation Cm Le l@ul
Geoenvironmental reports often include supplemental documentation, such as maps and copies of regulatory files, permits, registrations, citations, and correspondence with regulatory agencies. If subsurface explorations were performed, the report may contain final boring logs and copies of laboratory data. If remediation activities occurred on site, the report may include: copies of daily field reports; waste mani- fests; and information about Ihe disturbance of subsurface materials, the type and thickness of any fill placed on site, and fill placement practices, among other types of documentation. Do not sepa,afe sup- plemental documentation from the report. Do nof, and do not permit any other pady to redraw or modify any of the supplemental docu- mentalion for incorporation into other professionals' instruments of service.

U~detstand Le Role of Standards
Unless they are incorporated into statutes or regulations, standard practices and standard guides developed by the American Society for Testing and Materials (ASTM) and other recognized standards-devel- oping organizations (SDOs) are little more than aspirational methods agreed to by a consensus of a committee. The committees that devel- op standards may not comprise those best-qualified to establish methods and, no matter what, no standard method can possibly con- sider the infinite client- and project-specific variables that fly in the face of the theoretical "standard conditions" to which standard prac- tices and slandard guides apply. In fact, these variables can be so pronounced that geoenvironmental professionals who comply with every directive of an ASTM or other standard procedure could run afoul of local custom and practice, thus violating the standard of care. 12-1934
Accordingly, when geoenvironmental professionals indicate in their reports that they have performed a service "in general compliance1' with one standard or another, it means they have applied professional judgement in creating and implementing a scope of service designed for the specific client and project involved, and which follows some of the general precepts laid out in the referenced standard. To the extent that a report indicates "general compliance" with a standard, you may wish to speak with your geoenvironmental professional lo learn more about what was and was not done. Do nolassume a given standard was followed to the lefte~: Research indicates that that seldom is the case.

Realize Thal Recommendations May No1 Be Fiml
The technical reco~nmendations included in a geoenvironmental report arc based on assumptions about actual conditions, and so are preliminary or tentative. Final recommendations can bc prepared only by observing actual conditions as they are exposed. For that reason, you should retain the geoenvironmental professional of record to observe construction and/or remediation activities on site, lo permit rapid response to unanticipated conditions. Thegeuenvironmenfal professional who prepared the report cannot assume responsibility or liability for the reporth recommendations if that professional is ~d retained to observe relevant sire operations.

Understand Thal Geotechnical Issues Have Nol Beu Addressed Unless geotechnical engineering was specifically included in the scope of professional service, a report is not likely to relate any find- ings, conclusions, or recommendations about the suitability of sub- surface materials for construction purposes, especially when site remediation has been accomplished through the removal, replace- ment, encapsulation, or chemical treatment of on-site soils. The equipment, techniques, and testing used by geotechnical engineers ditter markedly from those used by geoenvironmental professionals; their education, training, and experience are also significantly differ- ent. ff you plan to build on the subject site, but have not yet had a geotechnical engineering study conducted, your geoenvironmental professional should be able to provide guidance about the next steps you should take. The same firm may provide the services you need. lPerl Responsibiliiy Rrvirions Closely
Geoenvironmental studies cannot be exact; they are based on prdes- sional judgement and opinion. Nonetheless, some clients, contractors, 2nd others assume geoenvironmental reports arc or certainly should be unerringly precise. Such assumptions have created unrealistic expectations that have led to wholly unwarranted claims and disputes.

To help prevent such problems, geaenvironmenlal professionals have developed a number of report provisions and contract terms that explain who is responsible for what, and how risks are to be allocated.

Sorne people mistake these for "exculpatory clauses," that is, provi- sions whose purpose is to transfer one party's rightful responsibilities and liabilities lo someone else. Read the responsibility provisions included in a report and in the contract you and your geoenvironrnental professional agreed to. Responsibility provisions are not "boi/ef- plate. "They are important.

SUBJECT: Section 24 Specific Plan Traffic Impact Study Dear Mr. Locacciato;
Endo Engineering is pleased to submit this analysis of the full range of potentially significant transportation consequences associated with implementation of the proposed Section 24 Specific Plan being prepared by the Agua Caliente Band of Cahuilla Indians. The Section 24 Specific Plan would coordinate the planning and future development of 577 acres under separate ownerships within the boundaries of the Agua Caliente Indian Reservation. The project site is undeveloped and located south of Interstate 10 and Ramon Road, north of Dinah Shore Drive, west of Bob Hope Drive, and east of Los Alamos Road. The site is west of the Agua Caliente Casino Resort Spa, within unincorporated Riverside County and the City of Rancho Mirage Sphere of Influence. The Section 24 Specific Plan area is surrounded on all four sides by the City of Rancho Mirage. Following action on the EIS and the Section 24 Specific Plan by the Agua Caliente Band of Cahuilla Indians, the Specific Plan area may be annexed to the City of Rancho Mirage.

The Riverside County General Plan would change the historical growth pattern of random sprawl by moving toward a pattern of concentrated growth and increased job creation in strategic areas, which provide various transportation options for access to the region. In view of its prominent and centralized location within the Coachella Valley, the proposed Section 24 Specific Plan would provide a unique opportunity to implement that vision. The proposed project would create a vital mixed-use development, within the context of a destination resort community, that is supportive of transit and other alternative transportation modes. The development would be pedestrian-friendly and located within an area where the use of golf carts and NEVs is commonplace and multi-use paths exist and are being expanded to accommodate cycling, pedestrians, and golf carts.

The development proposed would take maximum advantage of the opportunities afforded by the seasonal influx of tourists and part-year residents but also provide a mix of future uses that would support the local community and be economically viable year-round. To promote walking and cycling as healthy alternatives to commuting long distances by automobile, the Section 24 Specific Plan would provide a variety of housing options and create employment and entertainment opportunities in close proximity. Cohesive design elements would protect unique viewsheds and introduce streetscapes with coordinated landscaping to reinforce and enhance community aesthetics. The project would create a safe environment within which the use of alternative transportation modes for short trips would increase over time and continue to be a viable option as the population ages. 12-1951

1.0 INTRODUCTION AND SUMMARY

1.1 Purpose and Objectives
This traffic impact study was developed for use in the preparation of an Environmental Impact Statement (EIS) for the proposed Section 24 Specific Plan in Riverside County, California. The project site is located entirely within the Agua Caliente Indian Reservation and within the Sphere of Influence of the City of Rancho Mirage as defined by the Riverside County Local Agency Formation Commission (LAFCo). In compliance with their Environmental Policy Act (Tribal Ordinance No. 28) the Agua Caliente Band of Cahuilla Indians (“Tribe”) is acting as the lead agency for the preparation of the EIS.

Following action on the EIS and Section 24 Specific Plan by the Tribe, the Specific Plan area may be annexed to the City of Rancho Mirage. To facilitate compliance with the California Environmental Quality Act (CEQA) by the City of Rancho Mirage, the EIS will be prepared in compliance with the CEQA Guidelines.

This traffic impact study was conducted to provide an objective and factually supported full-disclosure analysis of the potentially significant transportation consequences associated with implementation of the proposed project as well as anticipated future discretionary actions and approvals. In the process, potential cumulative transportation impacts associated with other existing, approved, and proposed development in the study area were also evaluated. To achieve the objective, information was obtained from field observations in the study area, discussions with representatives of affected agencies and the project design team. Adopted plans and policies were analyzed. Available studies, reports, data, literature, and relevant local and regional transportation models were also reviewed.

The analyses summarized herein were designed to achieve the following objectives. • Describe the thresholds used to determine if a significant impact would occur. • Collect and analyze the data necessary to identify, disclose, and focus on those impacts determined to be potentially significant.
• Identify improvements that would avoid significant effects, where feasible. • Reduce adverse effects through the project design process or the incorporation of appropriate mitigation.
• Foster inter-agency coordination during the project review process. • Clearly document the study methodology, assumptions, findings, and recommendations to support informed decision making.

1.2 Site Location and Study Area
The 577-acre undeveloped project site is centrally located within the Coachella Valley, in unincorporated Riverside County.

Figure 2-1 depicts the project site in its regional context. The site occupies all of Section 24 except the 63 acres located on the east side of Bob Hope Drive. The project site is surrounded on all four sides by land located within t he City of Rancho Mirage and is within the City of Rancho Mirage Sphere of Influence. The project site is located south of Interstate 10 (I-10), near the recently constructed Bob Hope Drive interchange. The site extends south of Ramon Road to Dinah Shore Drive and west of Bob Hope Drive to Los Alamos Road (see Figure 2-2). The site is located south of Section 13, west of Section 19, and east of Section 23 (the Mission Hills golf resort community).

The study area extends east of Da Vall Drive to Monterey Avenue and south of I-10 to Gerald Ford Drive. Seventeen existing key intersections within the study area were identified and approved by the Tribe and the City of Rancho Mirage for peak hour delay and level of service analysis (as shown in Figure 3-1) to determine the traffic impacts of the proposed Specific Plan project. The City of Cathedral City is adjacent to the study area to the west and north. The City of Palm Desert is adjacent to the study area to the east.

1.3 Existing General Plan and Zoning Designations
The Riverside County Comprehensive General Plan (Revised 2008) and the Western Coachella Valley Area Plan (October 2003) assign three land use designations to the area within the project site: CR (120 gross acres), CT (217 gross acres), MDR (240 gross acres). These designations would allow up to 1,200 single family dwelling units and approximately 3.85 million square feet of non-residential building space associated with local and regional serving retail and service uses, 12-1957
1-2
tourist commercial, hotel, professional offices, recreational and amusement uses. 1 Development at the maximum intensity and density allowed by the Riverside County General Plan could generate up to 88,560 unadjusted weekday trips, as shown in Table 2-1. 2
The proposed Section 24 Specific Plan would establish development standards for consistent land uses (i.e., 1,200 single- family dwellings for active senior adults (aged 55 and above) and a maximum non-residential building area that represents

81.4 percent of the maximum allowed under the land use designations in the Riverside County General Plan. A maximum of 1,206 multiple-family residential dwellings not anticipated by the Riverside County General Plan are proposed in close proximity to the proposed local and visitor-serving retail and service uses that would be employment generators within the site. Even though the project would include approximately twice as many residential dwellings as the Riverside County General Plan , they would generate a similar number of residential trips because 1,200 dwellings would be for active adults (age-restricted for residents aged 55 and above). Development at the maximum intensity and density allowed by the proposed Section 24 Specific Plan could generate up to 73,890 unadjusted weekday trips, which is approximately 16.5 percent below the number of trips that would be generated by the amount and type of development allowed by the current Riverside County General Plan land use designations.

The City of Rancho Mirage General Plan applies a C-C designation to approximately 75 net acres within the site with the potential to generate approximately 33,100 weekday trips. The City of Rancho Mirage General Plan designates approximately 39 net acres of the site R-H (9 dwelling units per acre, maximum) which would allow up to 351 multi-family dwelling units. The remaining 414 net acres are designated R-M (4 dwelling units per acre, maximum) which would allow up to 1,656 single-family detached dwelling units. The proposed project includes 84 percent of the residential acreage shown in the City of Rancho Mirage General Plan. However, the multiple-family residential density proposed would be twice that allowed by the City of Rancho Mirage General Plan. The proposed project would include twenty percent more residential dwellings (2,406 versus 2,007 units). However, the residential trip generation of the proposed project would be 64 percent of that associated with the 2,007 dwelling units allowed by the City of Rancho Mirage General Plan (i.e., 5,590 f
ewer weekday trips, as shown in Table 2-1). The lower trip generation would be attributed to the 1,200 proposed single- family dwelling units for active senior adults (with residency limited to adults aged 55 and above), which would generate substantially fewer trips on weekdays than conventional single-family dwellings. Development at the maximum intensity and density allowed per the City of Rancho Mirage General Plan would generate a total of 48,780 unadjusted weekday trips.

1.4 Proposed Section 24 Specific Plan
The Section 24 Specific Plan would establish a unified vision for the project site to guide the future development of a cohesive and complementary mix of land uses consistent with both local and regional planning goals. The Section 24 Specific Plan provides comprehensive development standards and design guidelines for use in the future development of a mixed-use regional destination resort community with residential uses located near employment opportunities, tourist- related and local-serving commercial and entertainment uses. Offices and hotels would be permitted uses within the proposed Section 24 Specific Plan.
