Mitigation Monitoring and Reporting Program
Introduction
State California Environmental Quality Act (CEQA) Guidelines Section 15097 requires that when a public agency completes an environmental document which includes measures to mitigate or avoid significant environmental effects, the public agency must adopt a reporting or monitoring program for the changes to the project which it has adopted or made a condition of project approval in order to mitigate or avoid significant effects on the environment. The reporting or monitoring program must be designed to ensure compliance during project implementation.
The City of Riverside will coordinate monitoring and reporting of the implementation of the project- specific mitigation measures for the proposed project. Monitoring will include: (1) verification that each mitigation measure has been implemented; (2) recordation of the verification and any necessary notations regarding implementation of each mitigation measure; and (3) retention of records in the Tequesquite Sites and Santa Ana River Greenway, Riverside Gateway Parks Project Mitigation Monitoring file.

MM-BIO-1 Nesting Bird Surveys and Vegetation Clearing
Restrictions: Clearing of natural vegetation (including sage scrub) will be performed outside of the active
breeding season for birds, as defined in the MSHCP (March 1 through June 30) (MSHCP Volume I, Section 7.5.3),
except for Riversidian sage scrub (including distur bed) judged to be potentially suitable habitat for (and/ or
occupied by) coastal California gnatcatcher and loc ated within MSHCP criteria areas. For these areas, the h abitat removal restriction is extended from June 30 to Aug ust 15.
In addition, for riparian/riverine vegetation occup ied by least Bell’s vireo ( Vireo bellii pusillus ; LBV), or where work will occur in the buffer of an LBV nest, vegetation removal cannot occur through September 15. Table IV-5
summarizes the locations of (1) natural vegetation
communities within the limits of disturbance (LOD) that have the March 1 through June 30 restriction, (2) t he sage scrub with the June 30 and the August 15 clearing
restriction, and (3) the riparian/riverine vegetati on with a clearing restriction through September 15 (refer to
Appendix A, Figure 7, for an illustration of these
vegetation communities).
If clearing of vegetation needs to occur during these
timeframes, the following nesting bird survey requirements will be implemented.
1) A qualified biologist will perform a field survey of all nesting bird and raptor surveys. The biologist will
document the location of all nests within the project
and adjacent lands.

2) The results of the field surveys will be used to
determine an approach to address potential nesting
species. A single approach and methodology is not
adequate for all species. The approach and
methodology for avoidance of impacts on nesting birds
will be coordinated with the U.S. Fish and Wildlife
Service (USFWS) and CDFW, with final approval being
provided by both agencies. Below is a basic nesting bird survey method. This method is intended to provide
assurance that birds protected under the Migratory
Bird Treaty Act and similar protections under the
California Fish and Game Code will not be harmed.
3) Within 7 days prior to the commencement of
construction activities (if between the timeframes
specified above and as early as January 15 in areas
suitable for raptors), a qualified biologist will perform a nesting bird and raptor survey that will consist of at
least two site visits to each area with potential nesting habitat to determine whether there are active nests
within 200 feet of the project. This survey will also
identify the species, and to the degree feasible, nesting stage (e.g., incubation of young, feeding of young, near fledging). Nests will be mapped (not by using a global
positioning system, because close encroachment may
cause nest abandonment). If active nests are found,
construction will not occur within 200 feet of the nest, or as directed by a qualified biologist in coordination with USFWS and CDFW if necessary, as described
above, until the nesting attempt has been completed
and/or abandoned because of non-project-related
reasons. Burrowing owl surveys are addressed in MM-
BIO-2.
4) If suitable habitat for LBV occurs within 300 feet of the project construction area and it is within the LBV
breeding season (March 15 through September 15),

pre -construction surveys for LBV will occur by a
qualified biologist. These surveys will occur once a
week for three consecutive weeks during the breeding
season, and the last survey will occur no more than
3 days prior to the start of construction. All detections of LBV will be tracked for behavior across all detections by a qualified biologist. After the completion of
preconstruction surveys, weekly surveys will be
performed. If at any time it is determined that
construction activities are negatively affecting LBV,
including behavior modification, work will be halted
and CDFW and USFWS will be contacted for next steps.
During the nesting season, the following will apply:
i) Surveys will be conducted between dawn and
11:00 a.m. and not during inclement weather.
ii) Surveys will not cover more than 2 miles or 123
acres of habitat per day.
iii) Prior to performing surveys, a map will be created of all LBV habitat. During surveys, all LBV will be
mapped and tracked.
iv) Daily noise monitoring of LBV habitat adjacent to
construction activities will occur, with a qualified
biological monitor present to measure noise levels
at the edge of all suitable LBV habitat. Work will
cease if at any time noise levels exceed 60 decibels
(dB) unless ambient noise levels are in excess of 60
dBA. Noise monitoring will continue throughout
the breeding season or until construction activities
have halted within 300 feet of LBV habitat. For
areas where pre-construction ambient noise levels
exceed 60 A-weighted decibels (dBA), pre-
construction, ambient noise measurements can be
taken by a qualified entity during the full daylight
period (sunrise to sunset) and the median average

ambient noise level can be used as the baseline in
lieu of the 60 dBA. Where projects need to perform
nighttime construction activities, the same would
be done, but during the full nighttime period
(sunset to sunrise). If the project is not able to
reduce the noise, CDFW and USFWS can be
contacted on next steps.
Although not required, noise blankets between the
construction area and the LBV habitat can be used
to avoid the indirect effects of noise on LBV and to
reduce the construction halts. Even with the use of
a noise blanket, preconstruction surveys are
required unless USFWS and CDFW have confirmed
in writing that the surveys are not required.
Surveys were conducted for LBV in multiple years,
and LBV were found to be breeding only in the
following habitat types, so suitable LBV breeding
habitat is defined as black willow riparian
woodland, willow riparian woodland, southern
cottonwood – willow riparian forest, and southern
riparian scrub.
5) During operations, if suitable LBV habitat occurs within 300 feet of the project, the following will apply if
activities are to occur that would disturb LBV nesting
during the LBV breeding season (March 15 through
September 15):
i) No mowing or grass trimming will occur during the
nesting season without a survey for LBV nests by a
qualified biologist prior to these activities. If active nests are found, no mowing or grass trimming will
occur within 300 feet of the nest, or as directed by
a qualified biologist in coordination with USFWS
and CDFW if necessary, until the nesting attempt

ii) A Least Bell’s Vireo Avoidance Plan, which will
include strategies to reduce both noise and human
egress into LBV habitat. The plan will be created to
establish effective noise buffers and protect LBV
from human disturbance. The design of these
strategies will be included in the plan. Effective
strategies to buffer project operational noise from
LBV nesting habitat may include:
(1) Sound walls, incorporating features such as
green walls or vertical gardens. Vertical
gardens can enhance the value of these walls
for the park design, incorporating native plant
species and being better adapted to local
conditions. Vertical gardens also serve to
lower urban heat island effects.
(2) Water features or similar designs to create
white noise to mask disruptive sounds.
(3) Earth mounds, berms, or slopes.
(4) Strategically placed boulders or rocks/rock
walls.
(5) Dense vegetation, including evergreen trees
and dense shrubs, as long as the vegetation is
not suitable for nesting for LBV. The vegetation
must not include riparian vegetation, including
tamarisk.
(6) Quiet zones, minimizing human activity near
sensitive areas.
(7) A combination of these elements.
(8) Other approaches, as appropriate.

conducted within 30 days of disturbance. “Take” of active nests/burrows will be avoided. If burrowing owls are
detected during preconstruction surveys during the
breeding season, no relocation is allowed, and avoidance buffers will be established by the project biologist to protect the burrowing owl nest. Any passive relocation will only occur when owls are present outside the nesting
season, and only through appropriate authorizations
obtained through coordination with CDFW. Outside of the breeding season, if present and passive or active relocation is necessary, a Burrowing Owl Protection and Relocation Plan would be required. This plan would need to be
reviewed and approved with the Regional Conservation
Authority (RCA) and Wildlife Agencies, including the State banding permit office and the Federal Migratory Bird
Treaty Act office (for active relocation only) and this information will be included within the Burrowing Owl
Management Plan. Coordination with RCA and Wildlife
Agencies will occur during the preparation of the plan. The plan will be reviewed and approved prior to relocation.
MM-BIO-3 Fire Suppression: When work is conducted during the fire season (as identified by the Riverside County Fire
Department) adjacent to Riversidian sage scrub (Appendix A, Figure 6), appropriate firefighting equipment (e.g., extinguishers, shovels, water tankers) will be available on the project site during all phases of project construction to help minimize the chance of human-caused wildfires.
Shields, protective mats, and/or other fire preventive
methods will be used during grinding, welding, and other spark-inducing activities. Personnel trained in fire hazards, preventive actions, and responses to fires will advise
contractors regarding fire risk from all construction-related activities (MSHCP Volume I, Section 7.5.3).

MM-BIO-4 Biological Training: A qualified biologist will conduct a training session for project and construction personnel prior to grading, as per MSHCP Volume I, Section 7.5.3. The training will include a description of the species of concern and their habitats, the general provisions of the state and federal Endangered Species Acts and the MSHCP, the need to adhere to the provisions of the acts and the MSHCP, the penalties associated with violating the provisions of the acts, the general measures that are being implemented to conserve the species of concern as they relate to the
project, and the access routes to and project site boundaries within which the project activities must be accomplished (MSHCP Volume I, Appendix C). All sensitive areas will be fenced as presented in MM-BIO-6, below.
MM-BIO-5 Biological Monitoring: The qualified Project Biologist will monitor construction activities for the duration of the project to ensure that practicable measures are being
employed and avoid incidental disturbance of habitat and species of concern outside the LOD (MSHCP Volume I,
Section 7.5.3). Special attention will be provided to ensure that the environmentally sensitive area (ESA) fencing
required in measure MM-BIO-6 is maintained daily.
Additionally, ongoing monitoring and reporting will occur for the duration of the construction activity to ensure implementation of best management practices (BMPs). This will be done in concert with MM-BIO-6, below, which
includes the fencing of sensitive areas.
MM-BIO-6 Construction and Project Limits: Construction personnel will strictly limit their activities, vehicles, equipment, and construction materials to the proposed LOD and designated staging areas and routes of travel. The construction area(s) will be the minimal area necessary to complete the project and will be specified in the construction plans. Construction limits adjacent to sensitive resource areas will be

ESA fencing will be installed where sensitive biological resources have been identified by a qualified biologist. ESA fencing will be reviewed at least weekly by the biological monitor (as indicated in MM-BIO-5) until the completion of all construction activities. Employees will be instructed that their activities are restricted to the construction areas (MSHCP Volume I, Appendix C). Access to sites will be from pre-existing access routes to the greatest extent possible (MSHCP Volume I, Section 7.5.3, and MSHCP Volume I,
Appendix C).
MM-BIO-7 Exotic Species: Exotic plant species removed during construction will be properly handled to prevent sprouting or regrowth (MSHCP Volume I, Section 7.5.3). Exotic
wildlife species that prey upon or displace target species of concern should be permanently removed from the site to
the extent feasible (MSHCP Volume I, Appendix C).
Development adjacent to the MSHCP conservation area will not use the plant species listed in Table 6-2 of the MSHCP Volume I. The applicability of this list will consider the proximity of the planting area to the MSHCP conservation areas, species considered in the planting plans, resources to be protected within the MSHCP conservation area and their relative sensitivity to invasion, and barriers to plant and seed dispersal, such as walls, topography, and other
features.
MM-BIO-8 Equipment Cleaning: Construction equipment will be cleaned of mud or other debris that may contain invasive plants and/or seeds and inspected to reduce the potential of spreading noxious weeds before mobilizing to the site and before leaving the site during construction. The
cleaning of equipment will occur off site.
MM-BIO-9 Minimizing Disturbance: The removal of native vegetation will be avoided and minimized to the maximum extent

materials removed from the site will be disposed of in
accordance with applicable laws and regulations.
MM-BIO-10 Access: The permittee will have the right to access and inspect any sites of approved projects for compliance with project approval conditions, including BMPs (MSHCP
Volume I, Appendix C).
MM-BIO-11 Crotch’s Bumble Bee Pre-Construction Surveys: Pre- construction surveys for Crotch’s bumble bee should be
conducted no more than 30 days prior to any ground
disturbance that would occur between March and
September (the flight season). If pre-construction surveys identify occupied Crotch’s bumble bee habitat within the project area, the Project Biologist should notify CDFW and establish, monitor, and maintain no-work buffers around active nest colonies and any associated floral resources identified. The size and configuration of the no-work buffer should be based on best professional judgment of the
project biologist in consultation with CDFW. At a minimum, the buffer should provide at least 50 feet of clearance from construction activities around any nest entrances and
maintain disturbance-free airspace between the nest and nearby floral resources. Construction activities should not occur within the no-work buffers until the colony is no longer active (i.e., no bees are seen flying in or out of the nest for 3 consecutive days, indicating the colony has
completed its nesting season and the next season’s queens have dispersed from the colony).

direct night lighting during construction if activities occur at night. The MSHCP requires that shielding be
incorporated in project designs to ensure ambient lighting in MSHCP conservation areas is not increased (MSHCP
Volume I, Section 6.1.4). This would include PQP lands, MSHCP lands described for conservation (as outlined in the MSHCP Consistency Analysis), and existing reserve lands.
MM-BIO-13 LBV Habitat Temporary Impact Mitigation: Should temporary impacts on occupied LBV habitat occur, habitat compensation would be as described in MM-BIO-14. In
addition to habitat compensation, a monitoring program
would need to be established prior to the initiation of temporary impacts. A Least Bell’s Vireo Monitoring Plan for each temporary impact area would be created. The details of this plan would be based on factors such as the level of construction effort, potential to disturb LBV, time of year, level of restoration required, and other factors. The
monitoring effort would, at a minimum, include the
collection of baseline information regarding the current use of the habitat by LBV, documenting the presence or absence of LBV in the riparian area, planned mitigation efforts to avoid indirect effects on LBV during construction (if
present), a plan regarding biological monitoring of work during construction activities, required onsite restoration activities, restoration monitoring, monitoring for LBV
activity during the restoration monitoring period (LBV
territory data), and contingency measures in the event that LBV do not return to the riparian habitat during the
monitoring period.
MM-BIO-14 LBV Habitat Compensation: While not anticipated, the permanent removal of occupied LBV habitat will be
compensated at a minimum 3:1 ratio with compensation

occupied habitat temporarily removed during construction, restoration would occur at their original location at a 1.5:1 ratio. Creation and restoration potential is present at Camp Evans at Fairmount Park. Compensation for LBV impacts
should be coordinated with the MSHCP riparian/riverine
resources mitigation (MM-BIO-21 and MM-BIO-22) and
water permitting for time and monetary efficiencies.
Mitigation lands for the permanent removal of occupied
LBV habitat requires that the mitigation lands are riparian and contain suitable habitat to support LBV.
MM-BIO-15 Waste Management: To avoid attracting predators of special-status species, the project site will be kept as clean of debris as possible. All food-related trash items will be enclosed in sealed containers and regularly removed from the site(s) (MSHCP Volume I, Appendix C). Waste, dirt,
rubble, or trash will not be deposited in the Conservation Area or on native habitat (MSHCP Volume I, Section 7.5.3).
MM-BIO-16 Santa Ana River: Nesting Season Noise Requirements:
Between March 15 and September 15, all heavy equipment
will install and maintain mufflers or other noise-reducing features when working within 300 feet of the Santa Ana
River. A biological monitor will monitor and log sound
levels at the edge of the LOD with the riparian area to ensure noise levels do not result in a disruption to nesting birds (typically over 60 dB). If construction noise is
negatively affecting nesting birds, work will cease (unless authorized by the wildlife agencies) until adequate sound barriers can be constructed to reduce noise levels at the edge of the riparian corridor. It may be most effective to construct noise barriers well prior to March 15 to ensure construction delays do not occur. All noise barriers would need to be constructed within the LOD.

MM-TCR-1:
Implement Tribal Cultural Resources Protocols and
Measures Determined through Consultation
If it is determined that construction activities at the Martha McLean Anza Narrows Park and Jurupa Avenue Trailhead
sites would cause a substantial adverse change in the
significance of a TCR, the City should develop protocols and mitigation measures with consulting tribes, consistent with PRC Section 21080.3.2(a), to avoid or reduce impacts on TCRs during construction and
operation. Mitigation measures may include project
redesign or modification to avoid resources. The City shall develop minimization and avoidance methods where
possible with Native American tribes participating in AB 52 consultation to develop mitigation measures for TCRs that may experience substantial adverse changes.
In the absence of any
specific mitigation measures developed during AB 52
consultation, the City shall implement
standard mitigation measures set forth in PRC Section
21084.3 (b), as follows:
1. Avoidance and preservation of the resources in
place including, but not limited to, planning and
construction to avoid the resources and protect the
cultural and natural context, or planning

Construction personnel shall be informed about the types of archaeological resources that may be encountered and the proper procedures to be enacted in the event of an
inadvertent discovery of archaeological resources or
human remains. Workers shall be provided contact
information and protocols to follow if unanticipated
discoveries are made. The City and the lead construction firm (contractor) shall ensure that construction personnel are made available for and attend the training and retain documentation demonstrating attendance.
MM-CUL-2 Archaeological and Native American Monitoring: Avoidance is always the preferred method of treatment for
archaeological sites. Additionally, should sacred objects or objects of religious importance to Native American tribes be identified, preservation in place avoids conflicts with traditional values of tribes who ascribe meaning to these resources and their locations. Impacts on cultural resources can be avoided through establishing fencing around
cultural resources with a buffer and delineating these
locations as environmentally sensitive areas.
The appropriate buffer size shall be delineated upon
consultation with Native American tribes and the City
(for pre-contact resources). The City and the consultant archaeologist for individual development projects shall determine appropriate buffers for historical-period (non- Native American) archaeological resources on a case-by- case basis based on the known extent of archaeological
sites and the relationship to proposed ground disturbance.
If avoidance is not feasible and project-related ground disturbance is anticipated to occur at previously identified

The Native American monitor should be affiliated with a local Native American tribe. If project-related ground- disturbing activities in archaeologically sensitive areas are performed simultaneously in more than one location and
these activities are performed at a distance greater than 300 feet apart, an archaeological monitor should be present at each location. At a minimum, the archaeological monitor shall meet the Society for California Archaeology
professional qualification standards for an archaeological crew leader and shall work under the direction of an
individual that meets the Secretary of the Interior’s
Standards and Guidelines for Archaeology and the Society for California Archaeology professional qualification
standards for a Principal Investigator.
The archaeological monitor shall have the authority to
temporarily pause excavations, as needed, to examine
potential archaeological discoveries. In the event of an unanticipated discovery of archaeological resources or
human remains, the archaeological monitor shall follow the unanticipated discovery protocols described under MM-
CUL-3.
MM-CUL-3 Unanticipated Discoveries Protocol: If buried cultural resources are discovered inadvertently during ground-
disturbing activities, work should be temporarily halted in the area and within 50 feet of the find until a qualified archaeologist can assess the significance of the find and, if

If the discovery is determined to be not significant in consultation with the City, work shall be permitted to
continue in the area. If, in consultation with the City, a discovery is determined to be significant, a mitigation plan should be prepared and carried out in accordance with
state guidelines. If the resource cannot be avoided, a data recovery plan should be developed to ensure collection of sufficient information to address archaeological and
historical research questions, with results presented in a technical report describing field methods, materials
collected, and conclusions. The qualified archaeologist shall treat recovered items in accordance with current
professional standards by properly determining
provenance, cleaning, analyzing, researching, reporting, and curating them in a collection facility meeting the Secretary of the Interior’s Standards as promulgated in 36 Code of Federal Regulations Part 79.
MM-CUL-4 Human Remains and Associated or Unassociated Funerary Objects: The discovery of human remains is always a
possibility during ground-disturbing activities. If human remains are found, the State of California Health and Safety Code Section 7050.5 states that no further disturbance shall occur until the county coroner has made a determination of origin and disposition pursuant to Public Resources Code (PRC) Section 5097.98. In the event of an unanticipated discovery of human remains, the county coroner must be
notified immediately and all work within 100 feet of the find shall be halted until the remains have been evaluated by the county coroner. If the human remains are
