1 MITIGATION MONITORING AND REPORTING PROGRAM
Pedley Spreading Grounds Pond Enhancements Project
Mitigated Negative Declaration
State Clearinghouse Number 2023030023
Introduction
The City of Pomona prepared an Initial Study for the Pe dley Spreading Grounds (PSG) Pond Enhancements Project. Based on the inform ation contained in th e Initial Study, the City intends to adopt a Mitigated Negative Declaration (MND) for the project under the California Environmental Quality Act (C EQA). This Mitigation Monitoring and Reporting Program (MMRP) has been devel oped to ensure implementation of the mitigation measures outlined in the MND (State Clearinghouse No. 2023030023). The MMRP has been prepared by the City of Pomo na, the lead agency for the project under CEQA, in conformance with Public Resources Code Section 21081.6 and CEQA Guidelines Section 15097. Adoption of a MMRP is required for projects in which the Lead Agency has required changes or adopted mitigation to avoid significant environmental effects.
Project Description Summary
In collaboration with the City of Claremont, the City of Pomona intends to capture, treat, and infiltrate local urban runoff into the existing PSG to increas e water supply through stormwater recharge and to decrease non-point source pollutants. The project includes:
grading of the existing PSG basi ns to enhance percolation; modifications to an existing stormwater junction diversion structure; construction of a new control vault to improve stormwater conveyance to the basins; new water quality pret reatment structure; inlet storm drain extensions; energy dissipater a nd riprap pads; stilli ng basin and equalizer structures; spillways, access ramps and road way improvements; and Pedley Filtration Plant outlet interconnect piping and contro ls. Additionally, the project includes implementation of improvements (pathway, plan tings, educational signage, viewing area with benches, and a bike rack) at the Chaparral Park north of the PSG.
The Initial Study describes poten tially significant impacts of the proposed project on biological resources, cultural resources, geology and soils, hazards, water quality, noise, transportation, Tribal cultural resources, and utilities and service systems. Mitigation measures have been defined to reduce imp acts to less than significant levels. Other effects found to be less than significant are also described in the Initial Study.
Mitigation Monitoring and Reporting Responsibility
The City of Pomona shall have primary re sponsibility for administrating the MMRP activities to staff, consultants, or contractor s. The City has the responsibility of ensuring that monitoring is documente d through periodic reports a nd that deficiencies are promptly corrected. The City’s designate d environmental monitor will track and
2 document compliance with mitigation measures , note any problems that may result, and take appropriate action to re medy problems. Specific respons ibilities of the City of Pomona include:
Coordination of all mitigation monitoring activities
Management of the preparation, approval, and filing of mon itoring or permit compliance reports
Maintenance of records concerning the status of all approved mitigation measures Coordination with other agencies and relevant Tribal representatives
Resolution of Noncompliance Complaints
The City of Pomona Water Resources Departme nt will act as the contact for interested parties who wish to register comments or complaints. Any person or agency may file a complaint that states noncompl iance with the mitigation meas ures that were adopted as part of the approval process for the Pedley Spreading Basins Pond Enhancements Project.
The complaint shall be directed to City of Pomona Water Resources Department (148 N.
Huntington Street, Pomona, California 9176 8) in written form, providing detailed information on the purported violation. The City shall conduct an investigation and determine the validity of the complaint. If noncompliance with a mitigation measure is verified, the City shall take the necessary action(s) to remedy the violation. The complainant shall receive written confirmation indicating the re sults of the investigation or the final corrective action that was implemented to respond to the specific noncompliance issue.
Mitigation Monitoring and Reporting Plan Matrix
The MMRP is organized in a matrix format and includes: mitigation measure by number, impact summary, text of th e mitigation measures, time frame for monitoring, agency responsible, and space to indicate verification that the measures we re implemented. The MMRP matrix includes the mitigation measures identified in the Initial Study. In some cases, mitigation measures to protect biologi cal resources include additional detail to reflect comments received fro m the California Department of Fish and Wildlife.
Additional detail has also been added to the traffic control mitigation measures to reflect comments received from the California Depar tment of Transportation. The verification columns will be used to document the pers on who verified the implementation of the mitigation measure, the date on which this verification occurred, a nd any other notable remarks.

Construction Traffic Management Plan
Prior to commencement of construction
activities at a project site, the construction
contractor shall develop and implement an
approved Construction Traffic Management
Plan addressing potential construction-
related traffic detours and disruptions. In
general, the Construction Traffic
Management Plan would ensure that to the
extent practical, construction traffic would
access a project site during off-peak hours or
limit access during the peak hours; and that
construction traffic would be routed to avoid
travel through, or proximate to, sensitive land
uses. The Plan shall also include, where
necessary, the use of flags, signs and lights,
as well as flag persons to direct traffic. As

Unanticipated Discovery of Human Remains
and Associated Funerary Objects
A. Native American human remains are
defined in PRC 5097.98 (d)(1) as an
inhumation or cremation, and in any state of
decomposition or skeletal completeness.
Funerary objects, called associated grave
goods in Public Resources Code Section
5097.98, are also to be treated according to
this statute.
B. If Native American human remains and/or
grave goods are discovered or recognized on
the project site, then all construction activities
shall immediately cease. Health and Safety
Code Section 7050.5 dictates that any
discoveries of human skeletal material shall
be immediately reported to the County
Coroner and all ground-disturbing activities
shall immediately halt and shall remain
halted until the coroner has determined the
nature of the remains. If the coroner
recognizes the human remains to be those of
a Native American or has reason to believe
they are Native American, he or she shall
contact, by telephone within 24 hours, the
Native American Heritage Commission, and
Public Resources Code Section 5097.98
shall be followed.
C. Human remains and grave/burial goods
shall be treated alike per California Public
Resources Code section 5097.98(d)(1) and
(2).

200 feet away from discovered human
remains and/or burial goods, if the Kizh
determines in its sole discretion that
resuming construction activities at that
distance is acceptable and provides the
project manager express consent of that
determination (along with any other feasible
mitigation measures the Kizh monitor and/or
archaeologist deems necessary). (CEQA
Guidelines Section 15064.5(f).)
E. Preservation in place (i.e., avoidance) is
the preferred manner of treatment for
discovered human remains and/or burial
goods. Any historic archaeological material
that is not Native American in origin (non-
TCR) shall be curated at a public, non-profit
institution with a research interest in the
materials, such as the Natural History
Museum of Los Angeles County or the
Fowler Museum, if such an institution agrees
to accept the material. If no institution
accepts the archaeological material, it shall
be offered to a local school or historical
society in the area for educational purposes.
F. Any discovery of human remains/burial
goods shall be kept confidential to prevent
further disturbance.

TCR-5 Procedures for Burials and Funerary Remains
A. As the Most Likely Descendant (“MLD”),
the Koo-nas-gna Burial Policy shall be
implemented. To the Tribe, the term “human
remains” encompasses more than human
bones. In ancient as well as historic times,
Tribal Traditions included, but were not
limited to, the preparation of the soil for
burial, the burial of funerary objects with the
deceased, and the ceremonial burning of
human remains.
B. If the discovery of human remains
includes four or more burials, the discovery
location shall be treated as a cemetery and a
separate treatment plan shall be created.
C. The prepared soil and cremation soils are
to be treated in the same manner as bone
fragments that remain intact. Associated
funerary objects are objects that, as part of
the death rite or ceremony of a culture, are
reasonably believed to have been placed
with individual human remains either at the
time of death or later; other items made
exclusively for burial purposes or to contain
human remains can also be considered as
associated funerary objects. Cremations will
either be removed in bulk or by means as
necessary to ensure complete recovery of all
sacred materials.
D. In the case where discovered human
remains cannot be fully documented and
recovered on the same day, the remains will
be covered with muslin cloth and a steel

placed over the excavation opening to
protect the remains. If this type of steel plate
is not available, a 24-hour guard should be
posted outside of working hours. The Tribe
will make every effort to recommend
diverting the project and keeping the remains
in situ and protected. If the project cannot be
diverted, it may be determined that burials
will be removed.
E. In the event preservation in place is not
possible despite good faith efforts by the City
of Pomona, before ground-disturbing
activities may resume on the project site, the
City of Pomona shall arrange a designated
site location within the footprint of the project
property for the respectful reburial of the
human remains and/or ceremonial objects.
F. Each occurrence of human remains and
associated funerary objects will be stored
using opaque cloth bags. All human remains,
funerary objects, sacred objects and objects
of cultural patrimony will be removed to a
secure container on site if possible. These
items should be retained and reburied within
six months of recovery. The site of
reburial/repatriation shall be on the project
property but at a location agreed upon
between the Tribe and the City of Pomona at
a site to be protected in perpetuity. There
shall be no publicity regarding any cultural
materials recovered.

pro
ject’s qualified archaeologist to ensure

C&D Disposal Plan shall:
Identify the construction and demolition
waste materials to be diverted from
disposal by efficient usage, recycling,
reuse on the project or salvage for future
use or sale.
Determine if construction and demolition
waste materials will be sorted on-site
(source-separated) or bulk mixed (single
