Open Space Advisory Board Minutes May 10, 2023 Page 10 of 12 Ember asked if their master plan was based on more site -specific planning or on higher - level policy topics. Leslie said that they are hoping to expand out to the larger picture. David asked about the plans for trails and social trails on the Coyote Ridge property. Leslie said that one of the goals of the master plan is to evaluate the current trail network up there. Are there social trails that need to be eliminated or re-routed? Do they have enough trailheads and are they in the right places? 18. Discussion Item: Regional Trails, presented by David Blankinship, Louisville OSAB Chair & Ryan Welch, Superior OSAC Member Ryan began by showing a new bridge alignment for the Coal Creek Trail just off McCaslin. OSAC has wanted a better alignment and connectivity for this section of the Coal Creek trail. Leslie added that this alignment won't lead people into the neighborhood. David asked if the trail would be impacted by the riparian corridor. Leslie said that the riparian planning was done with the ditch company, the Mile -High Flood District. Jessamine asked about the proposal's timeline, Leslie said it should start in the fall, possibly opening in 2024. David asked if the surface would be gravel or concrete. Leslie replied that it would be a 10-foot concrete trail. David said most of the Coal Creek Regional Trail is gravel and it would be nice to keep the regional trail's surface consistent. Leslie replied that she felt like it was an accessibility issue and possibly a flooding issue to make it concrete. David asked if there was any stream modification planned. Leslie said after losing a lot of trees in the fire, the City is doing some bank stabilization, but it isn't directly part of this project. Leslie then showed a grant proposal for a 10-ft concrete trail parallel to McCaslin from Coalton Rd. to Rock Creek Parkway. It would not preclude the bike lane on McCaslin. Laura asked if e-bikes were allowed on trails in Superior. Leslie said they were "not unallowed." Ryan pointed out that there are some very fast e-bikes on the trail network, and a conflict might be coming up in the future. Michiko suggested that gravel trails should be for slower e-bikes only, and constrain the faster "class 3" e-bikes to concrete trails. David thought trail width might be a better determiner of speed limits than surfaces. Leslie pointed out that the proposed trail along McCaslin was also a nice 10-ft. fire break. Ryan said that the Superior OSAC and city government has been listing the Overlook Underpass Trail as their number one trail request recommendation to Boulder County. Another trail suggestion that they like is from the Coalton Trailhead, going west, on a section of trail informally called "The Dirty Bismark." Superior suggested a straight -shot, but the County likes an alignment along the creek. Jeff Moline from Boulder County, who was attending the meeting as a spectator, volunteered the information that the County is planning a re -surfacing of the current Coalton Trail alignment in November, most likely 12
