located further south (across Alessandro Boul evard), within the City and County of Riverside jurisdiction.

Existing Site Conditions
The City of Riverside General Plan 2025 (GP 2025) land use designation for the Project site is Business/Office Park (B/OP). The Project site is zoned BMP-SP – Business and Manufacturing Park and Specific Plan (Sycamore Canyon Business Park) Overlay Zones. The Project site is within the Sycamore Canyon Business Park Specific Plan (SCBPSP), which is considered a “Major Business Park” as shown on Figure LU-4 of the GP 2025. The SCBPSP designation for the Project site is Industrial.

The Project site is currently undeveloped and vacant. The topography consists of natural rolling terrain descending gradually from a west to east direction. The Project site contains two drainages, that cross the site from the southwest and south to the north. The Project site contains low to moderate vegetation primarily consisting of non-native grasslands and patches of sparse Riversidean sage scrub in the upland areas, with some riparian woodland associated with the drainages. The Project site contains an existing area of approximately 11.6 acres legally designated as “Restricted Property” (see Figure 3.0-3). The Restricted Property area supports a jurisdictional drainage and associated riparian habitat and was required as a condition of the Clean Water Act Section 404 permit from the U.S. Army Corps of Engineers for construction of the Grove Community Church at an off-site location, approximately one mile southwest. The Restricted Property is intended for preservation in a natural condition.

Discretionary Actions and Other Agency Approvals
The proposed Project would include site grading, construction, and operation of two warehouse buildings and associated improvements including parking, fire lanes, fencing and walls (including retaining walls), landscaping, and water quality treatment areas. The proposed Project will include the following actions and approvals by the City of Riverside and other agencies1:
x Tentative Parcel Map No. 36734 (P20-0025) – A Tentative Parcel Map is required to subdivide the Project site into two parcels (Parcels 1 and 2) and three lettered parcels (Parcels A, B, and C).

Overall construction is anticipated to last approximately 15 months. Grading and preliminary road construction is the first phase and is expected to last approximately 3 months. After grading, building construction will last approximately 12 months and includes slab and wall framing, concrete pouring, roof installation building interiors, Section 1.0 City of Riverside
Executive Summary Sycamore Hills Distribution Center Project

1.0-4
architectural coatings, parking lots, roadway improvements, landscaping, storm drains and water quality basins, etc.

The Project will involve grading and earthwork within the site in order to accommodate the proposed structures, associated parking lots, drive lanes, water quality basins and landscaped areas. It is anticipated that excavation of decomposed granite may be performed utilizing conventional earthmoving equipment. Blasting will not be required and is not proposed as part of the Project site preparation activities. During the grading phase, soil quantities within the overall site will balance and no export or import of fill from the site will be needed.

Operations and Employment
The Project is a speculative development, and the tenants are unknown at this time, so the number of employees, shifts, days and hours of oper ation are not known at this time. However, for the purposes of the analysis in the Environmental Impact Report (EIR), the estimated number of employees, using the County of Riverside Ge neral Plan Appendix E-2: Socioeconomic Build- Out Assumptions and Methodology
2, which uses a factor of 1,030 SF per employee, would be 388.3 employees for Building A and 197.2 employees for Building B, for a total of 586 (rounded to the nearest whole number) for both buildings.

Project Objectives
The proposed Project intends to achieve the following objectives:
x Develop the site with two warehouse buildings with a total of 603,100 square feet of building space, a conservation easement, and trailhead improvements. x Modify the Restrictive Covenant (RC) to allow access to Parcel 1, which is currently landlocked by the RC.
x Provide trailhead improvements consistent with the Sycamore Canyon Wilderness Park Stephen’s Kangaroo Rat Management Plan and Updated Conceptual Development Plan including:
o a parking lot,
o sidewalk,
o shade structure with benches,
o bike rack,
o drinking fountains,
o fencing, gates, signage, and a fire department access gate. 2 County of Riverside General Plan Square Feet/Employee Factor of 1,030 SF per employee for Light Industrial land use, Appendix E-2: Socioeconomic Build-Out Assumptions and Methodology, April 11, 2017, https://planning.rctlma.org/General-Plan-Zoning/General-Plan City of Riverside Section 1.0
Sycamore Hills Distribution Center Project Executive Summary

1.0-5
x Develop and operate warehouse buildings that:
o Take advantage of existing City infrastructure.
o Are adjacent to similar industrial logistics and distribution centers. o Are in close proximity to March Inland Port, State Route 60/Interstate 215, and Interstate 10 to support the distribution of goods throughout the region, while limiting traffic truck disruption to residential areas within the City and neighboring jurisdictions.
o Will attract quality tenants and will be competitive with other similar facilities in the region.
o Meet industry standards for operational design criteria. x Implement the Sycamore Canyon Business Park Specific Plan through development of a land use allowed by the industrial l and use designation and consistent with the development standards and criteria relevant to the site and proposed use. x Facilitate the development of underutilized land currently planned for industrial uses that maximizes the use of the site and responds to market demand within the Sycamore Canyon Business Park Specific Plan area for warehouse buildings. x Provide and expand on-site conservation to mitigate for the loss of riparian/riverine resources.
x Positively contribute to the economy of the City through new capital investment, creation of new employment opportunities, including opportunities for highly trained workers, and expansion of the tax base.

1.4 Alternatives
As required by the California Environmental Quality Act (CEQA), this DEIR examines alternatives to the proposed Project. Studied alternatives include the following three alternatives. Based on the alternatives analyses, Alternative 1 was determined to be the environmentally superior alternative.
x Alternative 1: No Project/No Development Alternative
x Alternative 2: Other Permitted Use/ Manufacturing
x Alternative 3: Reduced Development Alternative
Alternative 1 (No Project/ No Development):

As the Project is consistent with designated land use and zoning and the Sycamore Canyon Business Park Specific Plan, the “no project” alternative is no project development or no change from the existing use (vacant land). This alternative was selected based on CEQA requirements (Section 15126.6(e)).

Section 1.0 City of Riverside
Executive Summary Sycamore Hills Distribution Center Project

1.0-6
Alternative 2 (Other Permitted Use/ Manufacturing):

Manufacturing is also a permitted use within the BMP-SP – Business Manufacturing Park and Specific Plan (Sycamore Canyon Business Park) Overlay Zone. Alternative 2 consists of the same Project design, with manufacturing instead of warehousing as the use for the site. This alternative was selected as it is an allowable use under the existing land use, zoning, specific plan, and was anticipated to reduce potential impacts associated with trucks, including trip generation and VMT, and also associated air quality and greenhouse gas emissions. Other types of uses such as institutional (educational or religious), retail/ commercial, or residential would not meet the density/intensity standards of the compatibility Zone C1 of the MARB/IPA LUCP, resulting in an increase in potential impacts related to hazards, safety, and land use compatibility, as compared to the proposed Project.

Alternative 3 (Reduced Development Alternative):

The third alternative is a reduced development consisting only of the development of Parcel 1/Building A. Alternative 3 was identified and evaluated based on its the potential to reduce or avoid significant impacts related to VMT. In addition, as there are fewer physical cultural resources/tribal cultural resources in the eastern portion of the Project site, Alternative 3 would also reduce impacts to these individual resources as well as the larger TCL and TCP/TCR.

Refer to Section 8.0, Alternatives, for the complete alternatives analyses.

1.5 Areas of Known Controversy
The City of Riverside circulated an Initial Study and a Notice of Preparation (NOP) of the EIR for a 30-day agency and public review period st arting on July 28, 2020 and ending on August 27, 2020 at 5:00 p.m. The City distributed the NOP to the State Clearinghouse, responsible agencies, and other interested parties. Due to COVID-19 restrictions, the City held a virtual EIR Public Scoping Meeting on August 12, 2020, aimed at providing information about the proposed Project and the CEQA process to members of public agencies, interested stakeholders, and residents/community members.

shall be erected near the top
of slope adjacent to the
conserved riparian habitat to
prevent

MM BIO-6: (above)
MM BIO-7: In order to reduce potential
impacts to MSHCP covered species,
payment of the MSHCP mitigation fee
shall be provided to the City of Riverside
prior to issuance of a grading permit for
the project.

MM BIO-8: Payment of the SKRHCP fee
shall be provided to the City of Riverside
prior to issuance of a grading permit for
the Project.

MM BIO-9: If construction activity is
conducted between September 1
st and
January 31st, then this mitigation measure
is required prior to issuance of a grading
permit. Federal Migratory Bird Treaty Act
(MBTA) and/or state code protect all
native bird species - both common and
special status. In most scenarios, MSHCP
coverage does not override the nesting
bird protections provided by these.

Impacts to nesting birds, both direct and
indirect, can be minimized or eliminated
by conducting work activities outside of
the local breeding season. Although
nesting can occur in any month in
southern California for some species,
breeding in the study area, given the

habitat, would primarily be expected from
about 1 February through 31 August.

Work from about 1 September through 31
January would avoid most negative
affects to birds and nesting activity. If work
must be done during the breeding season,
surveys for nesting birds should occur no
more than three (3) days prior to all
vegetation clearing and ground
disturbance. If active nests are found, they
should be avoided until young have
fledged. While there is no established
protocol for nest avoidance, when
consulted the CDFW generally
recommends avoidance buffers of about
500 feet for raptors and
threatened/endangered species and 100
– 300 feet for non-raptors. Adherence to
these nesting bird recommendations will
also avoid and/or mitigate impact s to
special status bird species known from the
project site which are not covered by the
MSHCP.

MM BIO-10: A focused BUOW survey
must be conducted during the breeding
season (four visits between 1 March - 31
August). Regardless of the result of those
surveys, because of the presence of
suitable habitat that could be occupied at
any time, a one- day preconstruction
survey must also be conducted 30 days or
less before groundbreaking.

2.0 Introduction

2.1 Purpose and Scope
The purpose of this Environmental Impact Report (EIR) is to evaluate and disclose potential environmental impacts resulting from the implementation of the Sycamore Hills Distribution Center Project located north of Alessandro Boulevard directly east of Barton Street and west of San Gorgonio Drive. The EIR will also evaluate potential environmental impacts along associated streets and utility improvements (hereinafter referred to as the Project), as further described in Section 3.0 – Project Description of this DEIR.

This EIR is to serve as an informational document for the public and City of Riverside (City) decision makers. The process to finalize the EIR includes public hearings before the Planning Commission and City Council to consider certification of a Final EIR and approval of the Project.

2.2 Authorization
The EIR has been prepared by the City as the “Lead Agency” in accordance with the Guidelines for the Implementation of the California Environmental Quality Act (State CEQA Guidelines), (Sections 15000-15387 of the California Code of Regulations), and the City’s CEQA Guidelines.

The Project considered in this DEIR is a “project,” as defined by Section 15378 of the State CEQA Guidelines, which states that an EIR must be prepared for any project that may have a significant impact on the environment. The City, as Lead Agency, has determined that the Project may have a significant adverse impact on the environment; therefore, preparation of an EIR was required.

2.3 Lead and Responsible Agencies
CEQA defines a “Lead Agency” as the public agency that has the principal responsibility for carrying out or approving a project which may have a significant effect upon the environment.

Other agencies, e.g., Western Municipal Water District, California Department of Fish and Wildlife (CDFW), the Santa Ana Regional Water Quality Control Board (RWQCB), the U.S. Army Corps of Engineers (USACE) and the South Coast Air Quality Management District (SCAQMD) which also have some authority or responsibility to issue permits for project implementation, are designated as “responsible agencies.” Both the Lead Agency and responsible agencies must consider the information contained in the EIR prior to acting upon or approving a project. The City, as the Lead Agency, has determined the Project may have a significant adverse impact on the environment, and, therefore, preparation of an EIR is required. The City’s address is:

1. SCAQMD recommends that the SCAQMD’s
CEQA Air Quality Handbook and website be
used as guidance in preparing the air quality
and greenhouse gas analyses. SCAQMD
additionally recommends the CalEEMod
land use emissions software be used as
well, and further notes the California Air
Resource Board’s (CARB) Air Quality and
Land Use Handbook: A Community Health
Perspective as a general reference guide for
evaluating and reducing air pollution
impacts.

2. SCAQMD recommends the Project’s air
quality impacts be determined by comparing
Project criteria pollutant emissions to
SCAQMD’s CEQA regional pollutant
emissions significance thresholds and
localized significance thresholds. It is also
noted that potential adverse air quality
impacts from all phases of the Project
should be identified, and that air quality
impacts from construction and operation
should be calculated. It is additionally
recommended that a mobile source health
risk assessment be performed if the Project
generates diesel emissions.

3. The comment letter indicates that SCAQMD
should be identified as a Responsible
Agency should the Project require a permit
from SCAQMD.

4. SCAQMD expresses its staff’s concerns
about potential public health impacts of
siting warehouses within close proximity of
sensitive land uses and cites its Multiple Air
Toxics Exposure Study (MATES IV, May
2015).

5. SCAQMD provides a number of mitigation
measures it recommends the City consider
in the event the Project results in significant
adverse air quality impacts, including
measures for operational air quality impacts
from mobile sources and other area
sources.

CDFW recommends the DEIR identify mitigation
measures for the following topics;

1. Fully Protected Species: may not be taken
or possessed at any time. CDFW
recommends that the DEIR analyzes
potential adverse impacts to fully protected
species and that the City include in the
analysis how appropriate avoidance,
minimization, and mitigation measures will
reduce indirect impacts to fully protected
species.

2. Sensitive Plant Communities: the DEIR
should include measures to fully avoid and
otherwise protect sensitive plant
communities from Project-related direct and
indirect impacts.

3. California Species of Special Concern
(CSSC): CSSCs should be considered
during the environmental review process.

4. Mitigation: the DEIR should include
mitigation measures for adverse Project-
related impacts to sensitive species and
habitats. Mitigation measures should
emphasize avoidance and reduction of
Project impacts. For unavoidable impacts,
habitat restoration and/or enhancement, and
preservation should be evaluated and
discussed in detail.

intrusion, etc.
b. If sensitive species and/or their
habitat may be impacted from the
Project, CDFW recommends the
inclusion of specific mitigation in the
DEIR.
c. CDFW recommends that the DEIR
specify mitigation that is roughly
proportional to the level of impacts,
in accordance with the provisions of
CEQA.
d. CDFW is concerned of the
construction of an access road over
approximately 0.67 acres of lands
conserved under a restricted
covenant. CDFW recommends that
the City conduct a thorough analysis
of this proposal and include in the
DEIR an in-depth discussion
demonstrating that this proposal
represents an appropriate and
defensible mitigation strategy.

CDFW recommends that the City
include in the DEIR a discussion of
onsite habitat values and habitat
management activities conducted
pursuant to the Restoration Plan.

The DEIR should specifically
address how the mitigation proposal
will provide superior conservation
values. Copies of the Restoration
Plan and associated annual reports

An EIR is an informational document intended to inform decisions makers and the general public of potentially significant environmental impacts of a project. An EIR also identifies possible ways to minimize these potentially significant impacts (referred to as a mitigation) and describes alternatives to a project that may also reduce its significant impacts. Having the authority to take action on the proposed Project, the City Planning Commission and the City Council will consider the information in this EIR in their evaluations of the Project. The findings and conclusions presented in the EIR regarding environmental impacts do not control the City’s discretion to approve, deny, or modify the Project, but instead are presented as information to aid the decision- making process.

City of Riverside Section 2.0
Sycamore Hills Distribution Center Project DEIR Introduction

2.0-13
As set forth in Section 15021 of the State CEQA Guidelines, as Lead Agency, the City has the duty to avoid or minimize environmental damage where feasible. Furthermore, Section 15021(d) of the State CEQA Guidelines states that, “CEQA recognizes that in determining whether and how a project should be approved, a public agency has an obligation to balance a variety of public objectives, including economic, environmental, and social factors, and in particular the goal of providing a decent home and satisfying living environment for every Californian.” Other public agencies (i.e., Responsible and Trustee Agencies) that may use this EIR in their decision-making or permit processes will consider the information in this EIR along with other information that may be presented during the CEQA process. In accordance with CEQA, the public agencies will be required to make findings for each environmental impact of the Project that cannot be mitigated to below a level of significance. If the Lead Agency determines that the benefits of the proposed Project outweigh significant environmental effect s, the Lead Agency will be required to adopt a Statement of Overriding Considerations stating the reasons supporting its action notwithstanding the Project’s significant environmental effects.

Potentially Significant Environmental Effects
CEQA requires consideration and discussion of significant environmental effects. Section 15126 of the State CEQA Guidelines state that, “All phases of a project must be considered when evaluating its impact on the environment: planning, acquisition, development, and operation.” Section 5 of this DEIR will address each environmental effect that was determined to be potentially significant in the NOP (Appendix A). Each effect is organized into an issue area; those that will be analyzed (and the section of the DEIR in which the analysis is contained) are listed below:

City of Riverside General Plan 2025 Final Program Environmental Impact Report The City of Riverside General Plan 2025 Final Program Environmental Impact Report (GP 2025 FPEIR) was certified in 2007. The GP 2025 FPEIR provided a first tier analysis of the potential environmental effects of the adoption and implementation of the proposed General Plan, adoption and implementation of the comprehensive update of the Zoning Code and Subdivision Code, an amendment to the Noise Code, and adoption and implementation of the Magnolia Avenue Specific Plan as well as the adoption and implementation of the Citywide Design and Sign Guidelines. The GP 2025 FPEIR contains information regarding the environmental setting within the City and is available online at http://www.riversideca.gov/planning/gp2025program.

City of Riverside General Plan 2025
The City of Riverside General Plan 2025(GP 2025) was adopted in 2007. The GP 2025 is a long- range plan designed to control and regulate the growth in the City and to maintain the quality of the human and natural environment. The GP 2025 is the City’s planning “constitution,” or a blueprint for development, and is the single-most important policy document in guiding land use and development decisions within the City (GP 2025 FPEIR, p. 2-5). To that end, the GP2025 contains goals and policies that serve as the planning framework for the City in addition to providing direction for City operations and programs and serves as a guide to public and private decision making. The GP 2025 includes the following elements: Land Use and Urban Design, Circulation and Community Mobility, Housing, Arts and Culture, Education, Public Safety, Noise, Open Space and Conservation, Air Quality, Public Facilities, and Park and Recreation Elements.

The GP 2025 is available online at http://www.riversideca.gov/planning/gp2025program.

City of Riverside Municipal Code
The City’s Municipal Code complements the GP 2025. The Municipal Code, which contains among other ordinances, the City’s Zoning Code, is a mechanism to implement and enforce the goals, objectives, policies and programs articulated in the GP 2025. Many of the potential environmental concerns considered in this DEIR are adequately addressed through application Section 2.0 Cit y of Riverside

Sycamore Canyon Business Park Specific Plan and EIR
Originally known as the Box Springs Industrial Park Specific Plan, the Sycamore Canyon Business Park Specific Plan (SCBPSP) was originally adopted April 10, 1984 and has been amended 14 times. The SCBPSP describes a planned industrial park consisting of approximately 920 acres of industrial and commercial uses and a 480-acre wilderness park (Sycamore Canyon Wilderness Park) within an approximately 1,500-acre area. The purpose of the SCBPSP is to assure efficient, orderly, and attractive devel opment. To provide for orderly development, the SCBPSP was coordinated with the Sycamore Canyon Specific Plan and the General Development Plan for the Sycamore Canyon Park. The SCBPSP is available online at https://riversideca.gov/cedd/sites/riversideca.gov.cedd/files/pdf/planning/spec-plans/syc-bus- park/plan_doc.pdf.

The SCBPSP was the result of a complex series of circumstances. As the only large, undeveloped area of land not previously subject to detailed planning analysis, the site had been identified as a potential significant opportunity in economic re vitalization studies conducted in 1978. A number of studies covering the area occurred between when the Specific Plan was adopted. Important factors in these studies were preserving the land now known as Sycamore Canyon Wilderness Park and establishing land uses that would be compatible with what is now known as the March Air Reserve Base Airport Compatibility Plan available at http://www.rcaluc.org/Portals/13/17%20- %20Vol.%201%20March%20Air%20Reserve%20Base%20Final.pdf?ver=2016-08-15-145812- 700. A good portion of the property within the SCBPSP is impacted by the C1 – Primary Approach/Departure Zone and D – Flight Corridor Buffer Compatibly Criteria that limits other uses, such as residential uses, in this area.

Sycamore Canyon Wilderness Park Stephen’s Kangaroo Rat Management Plan and Updated Conceptual Development Plan.

The Sycamore Canyon Wilderness Park Stephens’ Kangaroo Rat Management Plan and Updated Conceptual Development Plan was prepared with two purposes: update the park’s conceptual development plan and provide a coordinated Maintenance/Management Plan for the endangered Stephens’ kangaroo rat (SKR). Because the Sycamore Canyon Wilderness Park was designated as a core reserve in the Habitat Conservation Plan (HCP) for the SKR, the City was required to prepare a Maintenance/Management Plan for the core reserve. The plan is available online at the City’s website:

3.1.1 Project Site – Existing Conditions
The Project site is currently undeveloped and vacant but has been used historically as open space. The topography consists of natural rolling terrain descending gradually from a west to east direction. There are granitic rock outcroppings throughout the property (see Figures 3.0-4A-E).

The Project site contains two drainages, Drainage A and Drainage B. Drainage A enters the site near the northern portion of the western boundary and flows for approximately 1,183 feet before exiting the site near the middle of the norther n boundary. Drainage B enters the site near the middle of the southern boundary and flows for approximately 981 feet before exiting the site near the middle of the northern boundary.

The Project site contains low to moderate vegetation primarily consisting of non-native grasslands and weeds as well as some riparian woodland. The non-native grasslands and weeds make up approximately 41 acres of the Project site and the riparian woodland makes up approximately 5 acres. Patches of sparse Riversidean sage scrub are present in the upland areas and make up a total of approximately 2 acres. The rest of the Project site is disturbed with no vegetation or exposed rock.

Several unpaved trails cross through the Project site and the drainages. The trails are not vegetated and are used by both people and animals. Several trails lead into the Sycamore Canyon Wilderness Park just north of the Project site and a couple trails lead into the private property to the east. These on-site trails are not identified as designated trails in the Sycamore Canyon Wilderness Park Stephens’ Kangaroo Rat Management Plan and Updated Conceptual Development Plan.

The Project site contains an existing area of approximately 11.6 acres legally designated as “Restricted Property” (see Figure 3.0-3). The Restricted Property area supports a jurisdictional drainage and associated riparian habitat and was required as a condition of the Clean Water Act Section 404 permit from the U.S. Army Corps of Engineers for construction of the Grove Community Church at an off-site location, approximately one mile southwest. The Restricted Property is intended for preservation in a natural condition.

Sycamore Hills Distribution Center Project Project Description

3.1.2 Project Site Background
The Project site was formerly owned by the Grove Community Church where a new church was planned to be constructed in the future. However, as the site is located within the C-1 Primary Approach/Departure Zone of the March Air Reserve Base/ Inland Port Airport Land Use Compatibility Plan, and due to restrictions regarding the height of the building and the maximum number of people allowed to congregate at any time, it was not conducive to the church’s plans.

March Joint Powers Authority (MJPA) assisted the church in finding a new location for the church, approximately one mile to the southwest at 19900 Grove Community Drive, Riverside.

Construction of the Grove Community Church at the off-site 19900 Grove Community Drive, location had impacts to a jurisdictional drainage and associated riparian habitat at that location.

To mitigate for impacts from construction of the church at the off-site location, the U.S. Army Corps of Engineers required that the on-site jurisdictional drainage and riparian habitat along Alessandro Boulevard be set aside and preserved in a legally designated “Restricted Property,” as a condition of the Clean Water Act Section 404 permit that was issued for the construction of the church. The “Restricted Property” was recorded in 2009.

MJPA purchased the Project site property from the church with the intent to sell and to convey title of the “Restricted Property” area to the City of Riverside. However, a parcel map was not created, and the title transfer did not take place. MJPA is still the owner of the entire Project site property. The Project applicant intends to purchase the property from MJPA upon project entitlement approvals.

The Project site and surrounding area has been the subject of City planning efforts since the early 1980s. To place the Project site and surrounding land uses into context, these efforts are described below.

Amended 1979 – Air Installation Compatible Use Zones
As amended in October of 1979, the Air Installation Compatible Use Zones (AICUZ) report for March Air Force Base, identifies aircraft noise and accident potential effects of the mission at March AFB. It also recommends land use plans, policies, and ordinances which are intended to ensure compatible relationships in the local environments of the base.

The bulk of property within the Sycamore Canyon Business Park is described as impacted by aircraft noise contours of 80 CNEL or above. In addition, a large area of land along the Atchison, Topeka and Santa Fe Railway (AT&SF) railroad is exposed to accident potential resulting from aircraft operations.

April 1984 – Sycamore Canyon Business Park Specific Plan and EIR Originally known as the Box Springs Industrial Park Specific Plan, the Sycamore Canyon Business Park Specific Plan (SCBPSP) was adopted April 10, 1984 and has been amended several times since its adoption. The SCBPSP encompasses approximately 1,500 acres, consisting of a 920-acre planned industrial park with industrial and commercial uses, and a 480- acre wilderness park (Sycamore Canyon Wilderness Park). The purpose of the SCBPSP is to Section 3.0 City of Riverside
Project Description Sycamore Hills Distribution Center Project

3.0-12
assure efficient, orderly, and attractive develop ment. To provide for orderly development, the SCBPSP was coordinated with the Sycamore Canyon Specific Plan and the General Development Plan for the Sycamore Canyon Park.

The SCBPSP was the result of a complex series of circumstances including: (i) the SCBPSP was the only large, undeveloped area of land not previously subject to detailed planning analysis; (ii) the SCBPSP area had been identified as a potenti ally significant development opportunity for economic revitalization; (iii) the adoption of the Arlington Heights Plan in 1979; (iv) the Southeast Study Area report adopted in 1980; and (v) the Air Installation Compatible Use Zones (AICUZ) (amended in 1979) for March Air Force Base. Important factors in these studies included preservation of the land now known as Sycamore Canyon Wilderness Park and establishment of land uses that would be compatible with what is now known as the March Air Reserve Base (MARB) Airport Compatibility Plan. Under the MA RB Compatibility Plan, a good portion of the property within the SCBPSP is impacted by the C1 – Primary Approach/Departure Zone and D – Flight Corridor Buffer Compatibly Criteria that limits other uses, such as residential uses, in this area.

April 1984 – Sycamore Canyon Specific Plan (SCSP) and EIR The Sycamore Canyon Specific Plan(SCSP) was adopted on April 10, 1984, to further the voter's intent shown by the passage of Proposition R with regard to protecting natural hillside and arroyo areas. Overall development levels established by Proposition R are the basis of the SCSP; however, the location and density of development was shifted within the SCSP area. This shift was made in order to protect Sycamore Canyon as a complete ecosystem, to the extent possible, within the limitations of the SCSP area and adjacent lands. The major thrust of the SCSP was to identify the area most appropriately preserved as open space in order to protect the various natural resources in and around Sycamore Canyon. The SCSP called for preservation of over 920 acres of land, of which about 450 acres are involved in the main canyon or its tributaries and the steep surrounding slopes. The remaining 470 acres to be preserved includes sensitive wildlife areas, archaeological areas, and linking areas, many of which have other special features such as rock outcroppings.

The SCSP provides for the development of perimeter portions of the site with residential and some commercial uses while protecting areas in and around Sycamore Canyon for open space.

The proposed residential uses allowed under the SCSP were broken out of the SCSP and were instead covered by the Lusk Highlander Specific Plan (now known as the Sycamore Highlands Specific Plan).

April 1984 – Air Installation Compatible Use Zones
An updated Air Installation Compatible Use Zones (AICUZ) report for the March ARB March Air Force Base Riverside County Comprehensive Land Use Plan (CLUP) was adopted on April 26, 1984. The CLUP placed the newly created SCBPSP into Area II. Area II was defined to be those areas of significant safety concerns due to aircraft maneuvering, ascending, descending, turning, and changing power settings when landing or taking off from the airport. Due to safety concerns, the City chose industrial use for Area II because it would potentially expose fewer people.

City of Riverside Section 3.0
Sycamore Hills Distribution Center Project Project Description

3.0-13
The AICUZ study has been updated a number of times since its 1984 adoption, with an updated study released in 2005 and the most recent released in 2018. The March Air Reserve Base/Inland Port Airport Land Use Compatibility Plan (discussed further below) is primarily based on the 2005 AICUZ study.

March 1999 – Sycamore Canyon Wilderness Park Stephens’ Kangaroo Rat Management Plan and Updated Conceptual Development Plan
The Sycamore Canyon Wilderness Park Stephens’ Kangaroo Rat Management Plan and Updated Conceptual Development Plan was prepared with two purposes: update the Sycamore Canyon Wilderness Park’s (Park) conceptual development plan and provide a coordinated Maintenance/Management Plan for the endangered Stephens’ kangaroo rat (SKR). The City was required to prepare a Maintenance/Management Plan because the Park was designated as a core reserve in the Habitat Conservation Plan for the Stephen’s Kangaroo Rat (SKR HCP) in Western Riverside County.

Adopted November 2014 – March Air Reserve Base /Inland Port Airport Land Use Compatibility Plan
The March Air Reserve Base/Inland Port Airport Land Use Compatibility Plan (March ARB/IPA ALUCP) was prepared for and adopted by the Riverside County Airport Land Use Commission (RCALUC). In accordance with provisions of the California State Aeronautics Act (Public Utilities Code Section 21670 et seq.), the RCALUC has been assigned the lead responsibility for airport land use compatibility planning around each of the pu blic-use and military airports in Riverside County, including the preparation of an ALUCP for eac h airport. With regard to military airports, Public Utilities Code Section 21675(b) states that Airport Land Use Commissions (ALUCs) must prepare a compatibility plan and that such plans “shall be consistent with the safety and noise standards in the Air Installations Compatible Use Zones plan prepared for that military airport” (RCALUC 2014). Accordingly, as previously me ntioned, the 2014 ALUCP is based primarily on the 2005 AICUZ study.

As noted on Map MA-1 of the March ARB/IPA ALUCP, the Project site is located in Compatibility Zone C1. Per Table MA-2 – Basic Compatibility, Zone C1, the Primary Approach/Departure Zone, permits most uses, including industrial but limit s the density/intensity of industrial uses and includes development conditions, such as discouraging aboveground bulk storage of hazardous materials and requiring airspace review for objects greater than 70 feet tall (MARB/IPA ALUCP, Table MA-2).

3.1.3 Land Use and Zoning
The City of Riverside General Plan 2025 (GP 2025) land use designation for the Project site is Business/Office Park (B/OP), Figure 3.0-5 Land Use Designation Map. The Project site is zoned BMP-SP – Business and Manufacturing Park and Specific Plan (Sycamore Canyon Business Park) Overlay Zones, Figure 3.0-6 – Zoning Map. The Project site is within the Sycamore Canyon Business Park Specific Plan (SCBPSP), which is considered a “Major Business Park” as shown Section 3.0 City of Riverside
Project Description Sycamore Hills Distribution Center Project
