concentrations?
Buildout of the project
would not result in a CO
hot spot. Additionally,
construction and
operation of future site-
specific projects would
not result in the exposure
of sensitive receptors to
TACs from construction
activities or stationary
sources. However, future
site-specific projects
within 500 feet of SR-71
and SR-60 could result in
the exposure of sensitive
receptors to substantial
concentrations of DPM
and impacts would be
considered potentially
significant.
AQ-3: Health Risk Assessment
For site-specific projects that may site new
sensitive land uses within 500 feet of SR-71 or
SR-60, the applicant shall prepare a HRA
evaluating the potential for sensitive receptors to
be exposed to TACs, which shall be required for
such individual projects. The HRA shall be
prepared in accordance with the policies and
procedures of the state OEHHA and the
SCAQMD. If the HRA shows that the incremental
cancer risk and/or noncancer hazard index
exceed the respective thresholds, as established
by the SQAQMD at the time a project is
considered (i.e., 10 in one million cancer risk and
1 hazard index), the project applicant will be
required to identify and demonstrate that best
available control technologies to reduce
substantial exposure of sensitive receptors to
TACs. Examples may include, but are not limited
to, air intakes located away from high-volume
roadways and/or truck loading zones unless it
can be demonstrated that these are operational

Bicycle-Truck Points of Conflict
ID
Roadway Segment
Extents Recommendation
1 East End Avenue
between Philadelphia
Street and Riverside Drive
The existing variable right-of-way presents a barrier to implementing bicycle facilities without widening the roadway. Reroute cyclists to parallel roadway (i.e., Pipeline Avenue) near-term and long-term invest in the bicycle facilities along East End Avenue and its connection to Philadelphia Street and Riverside Drive.
2 Riverside Drive between
Ficus Street and
Norton Avenue
Consider expanding the proposed Class II bicycle lane to Central Avenue to support connectivity with the Riverside Drive mixed-use boulevard.
3 Riverside Drive between
Central Avenue and
Oaks Avenue
Continue to invest in bicycle facility improvements, pending feasibility and congruency with the Riverside Drive mixed-use boulevard. 4 Schaefer Avenue
between Pipeline Avenue
and Mountain Avenue
As proposed by the project (see Figure 4.13-3), enhance existing Class II bicycle lane by adding buffers or converting it to a Class IV cycle track with physical barriers, such as bollards. Continue to improve with additional supportive treatments along the corridor and through intersections.
5 Pipeline Avenue between
Schaefer Avenue and
Eucalyptus Avenue
The existing constrained right-of-way limits opportunities for Class II bicycle lanes and/or separation. Consider rerouting cyclists onto parallel roadway (i.e., Norton Avenue), and invest further into upgrading that roadway to be a lower speed bike boulevard.
6 Monte Vista Avenue
between Schaefer
Avenue and Chino Hills
Parkway
The existing constrained right-of-way limits opportunities for enhancing existing Class II bicycle lanes with buffer or separation. If the roadway cannot be expanded for separation, require intersection treatments including green conflict markings across driveways and intersections, leading bike intervals, and additional signage and lighting. 7 Central Avenue between
Schaefer Avenue and
El Prado Road
As proposed by the project (see Figure 4.13-3), convert the existing Class II bicycle buffered bike lane to a Class IV cycle track with physical barriers to support concurrent truck and bike traffic.
8 Eucalyptus Avenue
between Pipeline Avenue
and Yorba Avenue
The existing constrained right-of-way limits opportunities for enhancing existing Class II bicycle lanes with buffer or separation. If the roadway cannot be expanded for separation, require intersection treatments including green conflict markings across driveways and intersections, leading bike intervals, and additional signage and lighting. 9 Eucalyptus Avenue
between Yorba Avenue
and Central Avenue
As proposed by the project (see Figure 4.13-3), convert the existing Class II bike buffered bike lane to a Class IV cycle track with physical barriers to support concurrent truck and bike traffic–where feasible, if not retain Class II bicycle lanes. In addition, require intersection treatments including green conflict markings across driveways and intersections, leading bike intervals, and additional signage and lighting. 10 Chino Hills Parkway
between Ramona Avenue
and Monta Vista Avenue
Enhance the existing Class II bicycle lane (on the south side of the roadway) by adding buffers or convert it to a Class IV cycle track with physical barriers. Install new Class II bicycle lanes, and if feasible, Class IV cycle tracks on the north side of the roadway. In addition, require intersection treatments including green conflict markings across Errata

driveways and intersections, leading bike intervals, and additional signage and lighting.
11 Chino Hills Parkway
between Monta Vista
Avenue and Central
Avenue
Existing bicycle lanes are present on both sides of the roadway along the existing sidewalk. Consider investing in on-street bicycle facilities, pending a feasibility study of right-of-way. Alternatively, invest in a dedicated bi-directional Class I shared use path on one side of the roadway.
12 Remington Avenue
between Flight Avenue
and Carpenter Avenue
Convert the existing Class II bike buffered bike lane to a Class IV cycle track with physical barriers to support concurrent truck and bike traffic, pending further feasibility. If not feasible, consider the implementation of Class I share use on one side of the roadway.
13 Flight Avenue between
Kimball Avenue and
Remington Avenue
The existing variable right-of-way limits the possibility of bike lane separation without widening the roadway. Consider investing in a Class I share use on one side of the roadway or rerouting cyclists to the Class I share use path along Hellman Avenue to the east of Flight Avenue. 1413 Hellman Avenue between
River Road and Walters
Street
The existing variable and constrained right-of-way limits opportunities for bike lanes and/or separation. Continue to invest in an off-street Class I shared use path on the west side of the roadway, which connects to an existing network of off-street facilities.

Summary of Staff Initiated Changes to the Project
In addition to the changes made to address the comment letters submitted during public review of the Draft PEIR described above, City staff revised the text of the General Plan Update elements as presented in the bullet list below. The changes listed below represent minor edits for clarification purposes and do not trigger any additional revisions to the Final PEIR beyond that presented above.
• Action LCC-3.C was revised to add off-site bicycle and trail facilities as a desired community benefit to be offered in exchange for bonus floor area ratio in the Boulevard Mixed Use and Regional Mixed Use districts.
• Action HEQ-2.C was deleted, which called for the establishment of a Safe Routes To School Advisory Committee and replaced with new Policy HEQ-2.6, recognizing that the standing Traffic Advisory Committee can fulfill the role envisioned for the proposed committee. • New Action HEQ-4.D was added calling for the City to consider amending the Zoning Code to incorporate regulatory or process incentives to encourage restaurants that serve healthy food.
• Action HSN-1.K was revised to reflect that the Municipal Code already prohibits the use of fireworks in areas of elevated wildfire risk.
• New Action HSN-2.G was added that calls for exploring the feasibility of offering incentives for commercial centers to install backup generators and/or solar batteries to increase energy resilience.
• Text in the Parks, Recreation and Community Services Element and in the Health and Environmental Quality Element was revised to clarify the acreage of the Prado Regional Park and that the park is overseen by the San Bernardino County Regional Parks Department, who lease the land from the U .S. Army Corps of Engineers and further sublease portions of that land to partner recreational organizations and businesses. • Policies INF -4.11, HEQ -8.15, and PRC -1.8 were revised to add text clarifying that local multi-use trail planning should be coordinated with regional trail planning initiatives to support a comprehensive active transportation network.
• Map INF -1 of the Infrastructure Element was revised to correctly present roadway classifications on the proposed circulation network.
• Maps INF-2 and INF -3 of the Infrastructure Element were revised to correctly represent planned bicycle facilities consistent with the adopted Bicycle and Pedestrian Master Plan. • Various photographs were replaced and various typographical errors and omissions were corrected in elements of the project.
