Outreach Summary
In order to deliver a project that is reflective of
community desires, the City solicited public input
to better understand existing usage, concerns, and
amenity preferences. This feedback was gathered
through a community survey, which was advertised
via direct mailers to households within 1/4 mile (or
1,320’ totaling about 600 mailers) of the project
corridor, signage posted at key Gage Canal access
points such as the Box Springs Mountain Reserve,
newspaper advertisements in the UCR Highlander
and Press Enterprise, social media postings on the
City’s Facebook and Instagram accounts, a City-issued
press release, and fliers posted around the city. Project materials and survey information were also included in
messages to parents of nearby schools in the Riverside
Unified School District and Alvord Unified School
District. The survey was available in both English and
Spanish, and was open for input between April 1 - May
30, 2021.
Technical Advisory Committee
The project team reached out to a group of
stakeholders who previously provided input on the
city’s Trails Master Plan (2021). This group met on
March 1, 2021, and again on June 14, 2021. Key topics
discussed included: the three main project zones
(industrial, Box Springs, residential); coordination with RCTC where rights-of-way overlapped with the project
corridor; access control at gateways and avoiding the
use of bollards; lighting and its interaction with trees; wayfinding; interpretive signage and themes; and
planting monarch butterfly host plants. The draft master plan was shared with this group to solicit feedback prior to finalizing the document.

CITY OF RIVERSIDE PARKS, RECREATION, AND COMMUNITY SERVICES Conceptual Plans
Introduction
For the purpose of design, the two-mile long trail
corridor has been split into three main zones.
The extents of each segment are based on the
surrounding land use context. The zones are:
• Residential Zone,
• from Blaine Street to Watkins Drive
• Box Springs Zone,
• from Spruce Street to Marlborough Road
• Industrial Zone,
• from Marlborough Road to Palmyrita Avenue
These zones have traits unique from one another that
have influenced the design approach of each safety
needs, wildlife habitat, trail function, cost benefit,
maintenance commitments, connections to adjacent
roadways, and levels of separation from adjacent
properties will vary from one zone to another.

GATEWAY CROSSING
26 ALTA PLANNING + DESIGN, INC.CITY OF RIVERSIDE PARKS, RECREATION, AND COMMUNITY SERVICES Gage Canal Multi-Purpose Trail Phase 1 Draft Master Plan Gateways and Access Points
Gateways are entryways at major intersections and
have the potential to reflect local culture and provide safe access to the Trail and across roadways. Gateways
will include a combination of the following features:
bicycle parking, seating, drinking fountains, trash
receptacles, dog waste stations, bicycle repair stations, trail wayfinding and informational signage. Existing
adjacent street parking may be available at some
gateways. Additional information on design features
appear in the Design Elements section on the following
pages.
Gateway Concept Alternatives
The concepts presented here show two alternative
approaches to gateway design for the Trail. A series
of vehicular access strategies are presented following
these two concepts, which can be applied to either
concept.
Gateway Concept 1: Composed +
Rectilinear
Inspired by the historical citrus groves in the city, this concept is directly connected to the use of modular
grids that give composition and proportion to the space.
The geometric form gives a feeling of balance, formality and unity.
SHARED USE PATH

UNPAVED PATH
27 ALTA PLANNING + DESIGN, INC.
Gage Canal Multi-Purpose Trail Phase 1 Draft Master Plan
CITY OF RIVERSIDE PARKS, RECREATION, AND COMMUNITY SERVICES Gateway Concept 2: Rhythmic +
Curvilinear
Characterized by meandering lines which mimic the
natural course of rivers or streams, this concept can
be described as smooth lines with deeply curved
undulations. The curved paths create an informal, calm, tranquil character that is associated more with nature
and asymmetrical balance.
SHARED USE PATH
UNPAVED PATH

28 ALTA PLANNING + DESIGN, INC.CITY OF RIVERSIDE PARKS, RECREATION, AND COMMUNITY SERVICES Gage Canal Multi-Purpose Trail Phase 1 Draft Master Plan Access Control
Maintenance access and the prevention of unauthorized
vehicles are significant considerations for gateway
and access point design. The safety of users must be
considered when proposing the use of access control
elements such as gates and bollards which can become
obstacles for trail users, and can lead to collision and injury. The access control alternatives presented below range from a level of lesser to greater entry control
and can be varied in implementation based on the
contextual conditions at a particular access point. It is anticipated that less entry control will be needed
Split Trail
The ‘split trail’ concept uses a combination
of a vehicular swing gate for maintenance
vehicles and a pedestrian/bicyclist entry
for trail users. Unimpeded access to the
Trail will be maintained for cyclists. The
planted median between the split trail will
discourage vehicles from entering while
allowing emergency vehicles to gain entry
if needed. This configuration would be
most appropriate for sections of the trail
that aren’t attractive to OHV or motorcycles
such as the southern residential section or
the northern industrial section.
Chicane
The ‘Chicane’ concept uses a combination
of a vehicular swing gate for maintenance
vehicles and separate pedestrian and
bicyclist entries. Easy access to the
asphalt-concrete path is maintained
for bicyclists while the curvilinear entry
configuration with offset tree planting
slows cyclists ahead of the intersection
and serves as a visual cue to dissuade
motor vehicles from entering. Like the ‘Split
Trail’ concept, this configuration is most
suited to areas of the trail that are less
attractive to OHV and motorcycles.
in the residential and industrial zones, while more
entry control may be needed for The Box Springs
Zone to prevent OHV or motorcycle entry into in the
reserve. Maintenance vehicle access driveways can
be configured with a rolled curb to differentiate them
from a standard vehicular driveway. Descriptions of the proposed options are as follows:
29 ALTA PLANNING + DESIGN, INC.
Gage Canal Multi-Purpose Trail Phase 1 Draft Master Plan
CITY OF RIVERSIDE PARKS, RECREATION, AND COMMUNITY SERVICES Swing Gate + Bollards
This concept provides more entry control
against unauthorized vehicles by utilizing
a combination of swing gate and bollards.
Integrating the multi-use path striping
into the entry plaza paving eliminates
the ‘road appearance’ of the path at the
entry point while the bollards are a visual
cue that motor vehicles are not allowed.
Maintenance vehicles access the trail
via a rolled curb and swing gate. This
configuration is suited to areas where
additional control is desired.
Swing Gate + Barriers
This concept provides the greatest level
of entry control against unauthorized
vehicles by utilizing a combination of swing
gate, fence, and bollard. Integrating the
multi-use path striping into the entry plaza
paving eliminates the ‘road appearance’ of
the path at the entry point while the bollard
is a visual cue that motor vehicles are not
allowed. Maintenance vehicles access the
trail via a rolled curb and swing gate. This
configuration is suited to areas deemed
most at risk of unauthorized vehicular use
such as the Box Springs section.
Roadway Crossing Treatments
Well-designed roadway crossings are essential for trail safety, convenience, and support continuous travel
experiences.
Where the Trail crosses public roadways, the typical
crossing treatment will be a Mid-Block Trail crossing,
with a high visibility crosswalk and warning signs to
alert people driving to the presence of potential trail users. Users of the Trail will cross roadways in parallel, with crossings striped separately for pedestrians and
cyclists.

Gage Canal Multi-Purpose Trail Phase 1 Draft Master Plan
CITY OF RIVERSIDE PARKS, RECREATION, AND COMMUNITY SERVICES Design Elements
The Trail will include elements such as trees, plants,
lighting, seating, and other user amenities. Trees and
lighting will be present along the entirety of the two mile long corridor, whereas amenities such as seating and
drinking fountains will be clustered at trail gateways.
Trail Elements
The trail will, for the most part, include a parallel
unpaved pedestrian path with concrete headers, and
an asphalt (Class I) bicycle path. Widened curb ramps
will be installed where the trail crosses roadways.
Striping and signage will be provided for the trail and street crossings. Access points to the trails will be
created at each street intersection, and will include
amenities such as benches, bike racks, water fountains, waste receptacles, fitness equipment and enhanced
landscape planting. The trail will be lit with solar lighting throughout its length, with a double row of trees where space allows.
Landscape
Tree planting patterns can be used to create a sense of uniformity or visual variation. Varying tree types along stretches of the corridor will allow for a denser planting of trees where space allows. A mix of tree species are
beneficial for establishing bio-diverse landscapes that are resilient to pests and drought. Tree patterns will
include those that are irregular and repeating, regular and repeating, or alternating form (see graphic below).
Trees planted along the trail will emphasize locally
native species, intermixed with pest and disease-
resistant species that are climate-appropriate. Tree
palettes will also reflect the surrounding industrial,
natural, and residential contexts. Trees will not be
planted directly above the canal pipeline and will be
placed as far away as possible to minimize the chance
for potential root intrusion to the canal wall.
Gateways will feature enhanced planting areas that will include additional native shrubs and ground covers as
well as modified tree palettes to include fruit trees or specimen trees that draw attention to the gateway.
The concept as presented includes 702 trees which
capture a total of 702.5 tons of CO2.

CITY OF RIVERSIDE PARKS, RECREATION, AND COMMUNITY SERVICES Water Quality Recommendations
Stormwater infiltration areas will be designed to
not seep below foundations of adjacent structures.
Because of the potential for erosion of existing slopes, we recommend that v-ditches that are planned for
surface water capture be maintained regularly. Based
on the assessment of subsurface conditions, the upper
5 feet of the soil profile between Columbia Avenue
and Watkins Drive can support infiltration; however,
we recommend that infiltration devices not be planned
north of Columbia Avenue and south of Watkins Drive,
as the factored infiltration rates in these areas of the Project would likely not exceed the minimum infiltration rate of 0.5 inch per hour required by the County of
Riverside (2006). Where practical, infiltration devices be planned a minimum of 5 feet from the proposed
shared use path.
Where space and infiltration rates allow, swales and
detention areas will be designed to slow and capture
runoff from the asphalt trail, and to control potentially erosive runoff from adjacent properties onto the trail.
As feasible, trail access points will integrate stormwater capture through bioswales and planted detention areas.
In accordance with the Low Impact Development (LID):
Guidance and Standards for Transportation Projects for
the Santa Ana Region Riverside County Co-Permittees,
LID-based Best Management Practices (BMPs) will be
incorporated into the project. Site considerations, soil conditions, and maximum drainage area, are considered
in choosing the best suitable BMP for a given location.
Considering the project conditions, infiltration trenches and bioretention facilities (bioswales) are recommended and varied based on adjacent conditions. In the
Residential Zone between Watkins Drive and Blaine
Street, bioswales are suggested due to existing
drainage structures in the area. Infiltration trenches
are recommended in both the Box Springs Zone
and Industrial Zone, between Columbia Avenue and
Spruce Street. In designing these BMPs in the Santa
Ana Watershed, they are sized based on their design
capture volume, VBMP. Using the spreadsheet shown
in Appendix #, the VBMP is estimated to be 6160 cubic
feet.

Gage Canal Multi-Purpose Trail Phase 1 Draft Master Plan
CITY OF RIVERSIDE PARKS, RECREATION, AND COMMUNITY SERVICES Geotechnical Analysis
Based on geotechnical considerations, the site is
suitable for the proposed improvements. The primary
geotechnical consideration was the variable soil
conditions encountered through the corridor, which
will impact the preparation of pavement subgrade and
the siting of infiltration devices. Minor cuts and fills will likely be required to construct the proposed paths and
infiltration devices. The earthwork for the proposed
shared use path will generally be minor and will
consist of cuts and fills within 2 feet of existing grades.
Overexcavation will not be required for the proposed
improvements. The recommended excavation bottoms
in cut areas and existing surfaces in fill areas should be prepared by:
• Scarifying the upper 6 inches
• Moisture-conditioning to above optimum moisture
content
• Compacting to at least 95% relative compaction
The fill and backfill should be compacted by:
• Placing in loose layers less than 8 inches thick
• Moisture-conditioning to above optimum moisture
content
• Compacting to at least 95% relative compaction
The compacted subgrade soils should be firm,
hard, and unyielding. Site grading may generally
be accomplished with conventional heavy-duty
construction equipment. The fill should be compacted
using soil compactors as recommended by the
Caterpillar Performance Handbook (2021) or equivalent.
Recommended minimum dense-graded hot-mix asphalt
(HMA) pavement sections deviate slightly from the City’s standard plan. The preferred pavement section will
look to minimize the overall excavation, while meeting
Caltrans design methods. The recommended minimum
pavement sections are based on the following:
• R-value of 50, which we judged to be conservative
based on the results of DYA’s laboratory testing
summarized in Section 3.2
• Caltrans (2020) design method
• Traffic index (TI) values of 5.5 and 6
Based on the previous considerations the pavement
sections are as follows:
• 3” HMA over 4“ Class 2 Aggregate Base over 6”
Compacted Native Soil
• 4” HMA over 4.5“ Class 2 Aggregate Base over 6”
Compacted Native Soil
• 5.5” HMA over 6” Compacted Native Soil
• 6” HMA over 6” Compacted Native Soil
34 ALTA PLANNING + DESIGN, INC.CITY OF RIVERSIDE PARKS, RECREATION, AND COMMUNITY SERVICES Gage Canal Multi-Purpose Trail Phase 1 Draft Master Plan Lighting
Lighting can be an effective tool for increasing trail user comfort, improving security and reducing the likelihood of unwanted behavior. Lighting provides a choice for
how to use trails during non-daylight hours. The goal of lighting trails for security is to make a place unattractive or uncomfortable to offenders while also providing
a sense of security and attracting the intended use
of trails. Properly lit trails should be easy to observe, eliminate potential hazards at intersections or access
points, attract use and enhance other environmental
design techniques.
According to the AASHTO Guide for the Development
of Bicycle Facilities, pedestrian-scale lighting is
preferred to tall highway style lights. Pedestrian-scale lighting is characterized by shorter light poles (standards about 15 ft high), lower levels of illumination (except at crossings), and closer spacing of standards (to avoid
dark zones between luminaires). Additionally, overhead
lighting is preferred to very low bollard lighting. Bollard lighting does not project sufficient light at eye level and distorts the available light due to the ‘up-lighting’ effect. This makes it difficult for users to recognize facial features, and diminishes their perception of safety. For these reasons, bollard lighting should only be used in
combination with overhead lighting or when overhead
lighting fixtures are not permitted or feasible.
GUIDING PRINCIPLES INCLUDE:
• Lighting will be at pedestrian scale. Placement,
spacing, and other finish specifications depends on
the fixture and optics
• Good lighting improves natural surveillance and
visibility
• Lighting will minimize energy usage, operating costs, light trespass, light pollution and glare
• Lighting will be placed at decision points and areas
of interest, such as street crossings, intersections
with other trails, trail spurs, and near commercial and mixed-use developments
• Lighting will use dark-sky compliant fixtures that
illuminate only the intended targeted areas and
minimize spillover onto adjacent properties.
• Lighting will include timers, sensors, and remote-
control technology which can enhance the sense of
security and conserve energy
• Light placement works hand-in-hand with tree
placement, and will be finalized as tree planting plans are completed.
APPLICATION
Lighting has been recommended per segment context
with consideration for safety needs, wildlife habitat, trail function, cost benefit, and maintenance commitments.
The Trail crosses through various surrounding land-uses and landscapes, including industrial, residential, and
sensitive environment areas that will allow for and/or
require different lighting solutions.
Lights are directional and are anticipated to be placed on one side of the trail, casting light onto the unpaved path and shared use path. Overhead lighting has been
selected for greater security and to achieve a fewer
number of total fixtures. For example, the segment
between Watkins and Marlborough would need six
times as many bollards to achieve the same illumination Firstlight SCL2 Series illuminaire at night

This determination will be made for the final concept,
once overall alignment and tree planting concepts are
determined.
Lighting calculations have been based upon a Firstlight SCL2 Series Illuminaire positioned at 16’ above the
ground using a type 3 lighting distribution pattern.
Furnishings and Amenities
Amenities that will be included in the trail corridor
design include seating, drinking fountains, trash
receptacles, and bike racks.
Seating contributes to the user experience by inviting
users to rest, congregate, or contemplate. Seating
opportunities along the trail provide a short relief
and also promote added enjoyment of the scenic
environment. Seating areas are designed to create
identity along the trail.
Drinking fountains are spaced at regular intervals that correspond with key gateways and landmarks. Locating
fountains with multiple heights will help accommodate
a range of user ages and physical abilities, as well as pets.
Trash receptacles are installed at trail entry points
and as-needed for user convenience. While requiring
dedicated maintenance, they will help prevent the
spread of refuse throughout the trail corridor and onto surrounding areas. The appearance should match other
trail amenities. Bicycle racks provide opportunities for trail users to use the trail as transportation, where users can engage in other activities without the worry of
losing their bicycles.
Additional amenities that may be included in the trail
design if funding allows are picnic tables, fitness
stations, and bicycle repair stations. Picnic tables
provide places for trail users to congregate for meals, relax, or have informal events. Bicycle repair stations are self-serve kiosks designed to offer a complete set of tools necessary for routine bicycle maintenance. Fitness stations are areas where outdoor fitness equipment
for workouts are included to enhance the recreational
opportunities on the trail.
Amenity palettes are provided in the following sections to match the character of each design zone. If the city prefers to keep amenities more consistent, the same
furnishing models can be used for all zones, and color
can be used as a differentiator.

The southern section of the Gage Canal Multi-Purpose
Trail, between Blaine Street and Watkins Drive runs
through a residential zone consisting of a mix of single family dwellings and multi-family residential complexes.
The plant palette in this section should complement
and reference some of the adjacent planting language
found in the surrounding residential area in order to
seamlessly integrate the future trail into the existing landscape. This can be accomplished by incorporating
smaller, residential-scale trees such as palo verde and mesquite to support a signature large oak tree.
Another approach to planting at trailhead gateways in
the residential zone is to create a community orchard.
A community orchard references Riverside’s rich
agricultural history, while providing an attraction for the trail. Long term fruit tree maintenance agreements may
be possible through community partnerships.
Lighting
This is the most densely populated section of the Trail project and therefore requires additional consideration to reduce light pollution for neighboring residents. In this section of the trail, residences are positioned on both sides of the trail, which requires that the lighting be controlled in both directions. Cut-off fixtures should be used to direct all illumination down towards the trail surface. Based on the Illuminating Engineering Society
(IES) lighting standards for pedestrian and bikeways,
lighting fixtures should be designed and placed to
produce between 0.2-0.5 foot-candles.
To achieve the recommended illumination of 0.2-0.5
foot-candles, the 2,280’ stretch of trail will require 23 total light fixtures spaced 100’ apart on center.
Urban orchards have been created at parks and trails in Los Angeles and Riverside. These provide an attraction for visitors and an interpretive link to local history.

The central section of the Gage Canal Multi-Purpose
Trail, between Spruce Street and Marlborough Avenue,
runs adjacent to the existing Box Springs Mountain
Reserve, a 3,400-acre nature preserve and park
operated by the County of Riverside. As the reserve
is primarily dominated by coastal sage scrub plant
community, the plant palette on this portion of the trail will primarily feature trees and shrubs native to Riverside and/or Southern California. Signature large trees in this section will include oaks and sycamore, and will be
supplemented by smaller, native trees such as desert
willow. The planting in this section should emphasize a connection to nature and a commitment to supporting
local biodiversity.
Lighting
In this segment the trail transitions to a more natural condition as it moves towards Box Springs. Here,
residences are found on just the east side of the trail before moving into the unpopulated Box Springs
Reserve. Like the Blaine to Spruce segment, cut-off
fixtures should be used to direct light down towards
the trail to eliminate light pollution to neighboring
residences. Sections of trail within the Box Springs
Reserve should have less lighting to limit disruption
to sensitive ecosystems. Lighting fixtures should be
designed and placed to produce 0.1-0.3 foot-candles
along this segment and use amber colored luminaires.
To achieve the recommended illumination of 0.1-0.3
foot-candles, the 4,255’ stretch of trail will require 36 total light fixtures spaced 120’ apart on center.

The northern section of the project corridor from
Marlborough Avenue to Palmyrita Avenue runs through
an industrial district known as Hunter Industrial Park.
It is characterized by large concrete tilt-up buildings and associated asphalt concrete parking lots. Through
this section, the proposed Gage Canal Multi-Purpose
Trail, is bordered on both sides by these industrial
buildings and parking lots, often in view of adjacent site operations.

The northern section of the Gage Canal Multi-Purpose
Trail, between Marlborough Avenue and Palmyrita
Avenue, runs through an industrial area dominated by
large warehousing and manufacturing operations each
of which feature their own campus and street adjacent
landscaping with various tree and shrub species.
Signature large trees on this section of the Trail can
reference and tie into the existing adjacent landscapes found along the corridor by featuring some of the same
trees present in the adjacent corporate campuses.
Examples of these include trees such as brisbane
box or aleppo pine. By tying into the adjacent existing landscapes, the Gage Canal through this section will
feel like a seamless addition to the existing fabric of industrial campus landscapes.
Lighting
The northern most segment of the Trail is surrounded
by industrial land use. For this reason, spill-over from lighting fixtures is less of a concern and illumination of the trail surface can increase. Cut-off fixtures are not necessary in this location and the illumination
range should be designed within .5-1 foot-candles.
Additionally, trailheads should be designed with an
illumination of 1 foot-candle to facilitate user access to the trail.
To achieve the recommended illumination of 0.5-1.0
foot-candles, the 2808’ stretch of trail will require 35 total light fixtures spaced 80’ apart on center.
