Technical Advisory Committee Meeting #1
2:00pm – 3:00pm
I. Introductions
II. Project Background
a. One of the things we were looking for in the gateways seating, amenities, water, interpretive panels re: canal history; would like to get any additional info re: gage canal from folks that have been around for a while; gage middle school mural has neat interpretive exhibit re: gage canal history; would like to make sure that when bikes and walkers are crossing, there are some dividers from traffic. What about interpretive panels? Can that include info re: GHG and other environmental information? We are open to input. We should interpret the urban greening element for the public as well. We also want to build resilience into the project from a sustainability element. Looks like the trees will outcompete the solar.
III. Project Walkthrough / Key Challenges
• Have you discussed this with RCTC? We have trail access along the entire metrolink row. We should us it. Settlement agreement. RCTC should be at the table for this section. • Public record, should be on RCTC. Will track down and forward to consultant. • Is that the boundary to grand terrace? Does trail continue into next city? We know we’ll need environmental work and to get crossing. We are able to go all the way to Spring in future iteration.
IV. Crossings (Blaine, Columbia, Palmyrita)
a. Trails would converge at gateways before crossing so all trail users would cross at one location V. Design Considerations
a. Three Project Zones
1. Industrial: Security, lighting, existing disturbance
2. Box Springs: Lighter Touch, trees, lighting will be more directed to keep it out of homes and Box Springs, Views
3. Residential: existing bike path, lighting will need to be directed and not spilling into adjacent residences
b. Landscape: low water use species, will decrease over time as trees become established, 15-gal size
1. Native California, Industrial Park, Options; we aren’t going to monocrop the trees; landscape design will be context driven
2. Gateways can call out agricultural history by creating an urban orchard c. Lighting: keep trail secure and increase user enjoyment; solar lighting. We will need to work with manufacturers to specify models where solar panel is above tree canopy, and luminaire is below 66 ALTA PLANNING + DESIGN, INC.
Gage Canal Multi-Purpose Trail Phase 1 Draft Master Plan
CITY OF RIVERSIDE PARKS, RECREATION, AND COMMUNITY SERVICES canopy. We will be working with best practices for trail lighting • What about battery life expectancy?
• Is there an option for centralized solar panel location re: gateway (could be integrated into shade structure + battery)
• Did you have to compute the amount of carbon sequestration? City does have a plant list. There is opportunity to get more detailed in the planting as long as we get the same amount of carbon sequestration.
• We are working on expanding the plant list submitted for the grant. • Does anything take into account tree maintenance in the grant? As part of construction contract, we can perhaps extend the maintenance period. Will have to verify. If structural pruning is needed when trees are young, perhaps an urban conservation corps could be involved. Job training. Beginner arborist training. d. Amenities: Signage, seating, bike racks…what would be really valuable to add? • Pop up espresso stations
• Overall trail map (showing local connections)
e. Misc. Comments: Crossings themselves should have separate bike crossing markings, connection at Watkins is there budget to make sidewalk wider and just leave it unmarked like Irvine has done? No bollards please. City has issue of people driving down the trails. Having a small median is better. Swing gates, ‘maze’ gate option. Water opportunity recommend bottle filler station (work great for peds and cyclists). Trees look great when they go in, then start lifting the trail (root barriers?, distance from trail). Nice to have small pullout eg. 8-foot half dome with natural rocks so people can stop for breaks, phone calls etc. every ¼ to ½ mile. Donkeys are beginning to come this way. Connection to industrial properties so employees can use trail adjacent to the industrial section. Barnyard style gates work better for peds than gates that come down from above. Can we tap into Gage Canal water directly?
f. Erosion issues – make sure these are addressed; narrow portion that goes around box springs, may need small drainage ditch and maybe periodic drainage structures. Like the idea of the 3 contexts; doesn’t have to be the same along the full corridor.
VI. Next Steps
a. Draft Master Plan – Late March
b. TAC Meeting #2 – Early April
c. Design – Complete October 2021
d. Construction – December 2021 – August 2022
