SUBTT20854, as described in the title of this Resolution. Hereinafter in this Resolution,the subject
Tentative Tract Map request is referred to as "the application."
2. On the 10th day of December 2025, the Planning Commission of the City of
Rancho Cucamonga conducted a duly noticed public hearing on said application and concluded
said hearing on that date.
3. All legal prerequisites prior to the adoption of this Resolution have occurred.
B. Resolution.

2. Based upon the substantial evidence presented to this Commission during the
above-referenced meeting on December 10,2025, including written and oral staff reports,together
with public testimony, this Commission hereby specifically finds as follows:
a. The application applies to an unimproved site located between Wilson Avenue and
Banyan Street, east of the Deer Creek Channel and west of Milliken Avenue at APN 0201-19-127;
and
b. The project site is made up of one(1) parcel of land with an area of approximately
39.22 acres. The eastern and western property lines border the Deer Creek Channel and Milliken
Avenue respectively; and
C. The existing land uses, General Plan land use designation, and zoning
designations for the project site and the surrounding properties, relative to the above-noted parcel,
are as follows:

d. Tentative Tract Map SUBTT20854 is for the subdivision of a 39.22 acre parcel into
two hundred thirty-one (231) numbered lots and eleven (11) lettered lots for the development of
single-family, detached residences.Access to the lots will be provided through a private drive aisle
off Banyan Street; and
e. The overall project scope includes Tentative Tract Map SUBTT20854.
3. Based upon the substantial evidence presented to this Commission during the
above-referenced meeting and upon the specific findings of facts set forth in Paragraphs 1 and 2
above, this Commission hereby finds and concludes as follows:
a. The tentative tract map is consistent with the General Plan and Development
Code. The project site is being subdivided to facilitate the development of two hundred thirty-one
(231) single-family residences that comply with the proposed amendments being
considered simultaneously to the Etiwanda Heights Neighborhood and Conservation Plan
(EHNCP) and are consistent with the Traditional Neighborhood General Plan land use
designation. The site is physically suitable for the proposed subdivision.The proposed tentative
tract map will subdivide one (1) existing, unimproved parcel into two hundred and thirty-one (231)
numbered lots and eleven (11) lettered lots for the development of two hundred and thirty-one
(231)single-family units. The building types and general size and layout of the lots are
consistent with the proposed amendments being considered simultaneously to the
Etiwanda Heights Neighborhood and Conservation Plan.
C. The design of the subdivision is not likely to cause substantial environmental
damage and avoidable injury to human and wildlife or their habitat. The scope of the project is the
subdivision of one (1) unimproved parcel into two hundred and thirty-one (231) single-family lots.
The project site is surrounded by residential development and is in keeping with the proposed
amendments being considered simultaneously to the Etiwanda Heights Neighborhood and
Conservation Plan. Additionally, the City has prepared an addendum to the Certified Final
Environmental Impact Report (FEIR) (SCH #201711102) prepared for the Etiwanda Heights
Neighborhood and Conservation Plan.The proposed amendments do not substantially increase the
severity of effects relative to the topics analyzed in the FEIR, nor would the amendments require
new mitigation measures or alternatives; and
PLANNING COMMISSION RESOLUTION NO. 2025-043

Page 3
d. The tentative parcel map is not likely to cause serious public health problems.The
scope of the project is the subdivision of one (1) unimproved parcel into two hundred thirty-one
231 residential lots. A CEQA Certified Final Environmental Impact Report (FEIR)
(SCH #201711102)was prepared for the Etiwanda Heights Neighborhood and Conservation
Plan,which determined the impacts the project would have on the environment in relation
to biological resources,traffic, noise, air quality, or water.An addendum to the FEIR has been
prepared showing that no new information of significance has become available nor have any
substantial changes occurred to the circumstances since the certification of the FEIR, thus the
proposed amendments will not have a significant effect on the environment; and
e. The design of the tentative tract map will not conflict with any easement acquired
by the public at large, now of record,for access through or use of the property within the proposed
subdivision. The subject subdivision does not conflict with existing public rights of way or existing
easements.
4. Pursuant to the California Environmental Quality Act (CEQA) and the State's CEQA
Guidelines,the City has prepared an addendum to the Certified Final Environmental Impact Report
(FEIR) (SCH #201711102) prepared for the Etiwanda Heights Neighborhood and Conservation
Plan. The addendum concludes that the proposed amendments do not result in any new significant
environmental effects or a substantial increase in the severity of previously identified significant
effects beyond what was analyzed in the FEIR. No new information of substantial importance has
become available nor any substantial changes to the circumstances since the FEIR certification
occurred. The proposed amendments do not substantially increase the severity of effects relative to
the topics analyzed in the FEIR, nor would the amendments require new mitigation measures or
alternatives. Based on this evidence and all evidence in the record, the Planning Commission
recommends that the City Council concur with Planning Department staffs determination that the
proposed amendments will not have a significant effect on the environment, and an addendum is
the appropriate level of environmental review under CEQA.
5. Based upon the findings and conclusions set forth in Paragraphs 1, 2, 3, and 4 above,
this Commission recommends that the City Council approve the application subject to each and
every condition set forth in the Conditions of Approval, attached hereto and incorporated herein by
this reference.
6. The Secretary to this Commission shall certify the adoption of this Resolution.

Section XI.D(Water Quality Management Plan Requirements).8(Groundwater Protection):
Treatment Control BMPs utilizing infiltration [exclusive of incidental infiltration and BMPs not designed to
primarily function as infiltration devices (such as grassy swales, detention basins, vegetated buffer
strips, constructed wetlands, etc.)] must comply with the following minimum requirements to protect
groundwater:
a. Use of structural infiltration treatment BMPs shall not cause or contribute to an exceedance of
ground water quality objectives.

purposes').
d. Unless adequate pre-treatment of runoff is provided prior to infiltration structural infiltration treatment
BMPs must not be used for areas of industrial or light industrial activity{77), areas subject to high
vehicular traffic (25,000 or more daily traffic); car washes; fleet storage areas; nurseries; or any other
high threat to water quality land uses or activities.
e. Class V injection wells or dry wells must not be placed in areas subject to vehicular{78) repair or
maintenance activities{79), such as an auto body repair shop, automotive repair shop, new and used
car dealership, specialty repair shop (e.g., transmission and muffler repair shop) or any facility that does
