Lime Ridge Flow Trail Project Moves Forward

The Walnut Creek Parks Recreation Opens Space Commission (PROS) met on 8/14/23.  The main agenda item was an update on the Lime Ridge flow trail and actions from the December 2020 Trails Subcommittee Report.  Public Works Manager Mike Vickers and Ranger Corey Frazier gave updates on the flow trail project, Trails Committee recommendation progress, and other trail open space activity.  

Mike Vickers presented on the flow trail progress with the main milestone being completion of the CEQA Initial checklist evaluation completion and determination to file a mitigated negative declaration which would allow the project to move forward without performing a full environmental impact report (EIR).  This is supported by the lack of impact identified in the  checklist and supported by field stewardship surveys.   Staff published the mitigated negative declaration beginning the 30-day public comment period which ended September 30th.  Comments will then be addressed and then forwarded to the City Engineer for certification following the 30-day public comment period barring any issues being raised that require further work.  Mike Vickers and Public Works Director Heather Ballenger have authority to move forward on flow trail construction once the CEQA determination is certified. This does not require approval by the PROS commission, City Council, or Mayor.  

Public Works Manager Mike Vickers vigorously addressed a number of the Rancho Pariso / Timberleaf Court resident points of concern including crime and security, environmental evaluation and stewardship surveys, parking, and Timberleaf court emergency access.  Staff have addressed these concerns in each of the public meetings.  He also covered a detailed history of the change in use to the Timberleaf trail to multiuse years ago and issues with that signage.  

Ranger Corey Frazier reported on a variety of trail/road maintenance and repair, trail closure restoration progress, other open space improvements, and volunteer trail work. Staff have accomplished a significant amount of work in during the past year.  Mike Vickers also updated on the 2022 Trails Sub Committee recommendations and which ones had been acted on and those that had not.  Item H – Evaluate all OS singletrack to make recommendations on changes to trail designations, J – Evaluate the trails proposed – set trail use designations, names, K – Partner with orgs such as BTCEB to promote trail safety and get bike community behind closure and restoration, O – Develop and implement Volunteer Patrol Program, and P – Give OS  Rangers training and ability to issue citations at their discretion had not been acted on yet.   A volunteer patrol was discussed briefly and singletrack trail recommendations were not discussed.

There were about 40 live public comments made with more in person than remote. Pro/con were roughly evenly split.   Written comments posted up to the meeting time were about 76 for and 51 against.  There were youth written comments. Some of the opposing attendees in attendance were interrupting supporting speakers and were directed several times by Chair Fran Garland to stop.  Chair Garland took a 10 minute recess at one point to get control of the behavior by some of the opposing attendees.  Thanks to all that made public comment supporting increased access.  

Staff addressed objections raised to the project as they have been throughout the  process in multiple meetings.  They have conducted a very public process and continue to move forward in bringing legitimate mountain bike access and a new trail to Lime Ridge.

Briones Pilot Survey and September 2023 Update

The East Bay Regional Park District Briones Pilot has issued a new feedback survey.   Please take a few moments to provide feedback.   This is part of their data collection that will feed into their upcoming 6 month update.  It’s important as stakeholders to participate and share your thoughts.

The September 9th Community Dig Day was focused on restoration of Lower Cookies.   This was the second consecutive dig day with a natural resources restoration scope.  The Stewards of Briones are planning their first sanctioned dig day in partnership with EBRPD staff and focusing on Radio Tower.  The aim is to get some water supply support to accomplish some effective tread work despite still being in the dry season.  

East Bay Regional Parks Approves E-Bikes!

The East Bay Regional Park District Board voted 5-0 to approve class 1 e-bike access to natural surface roads and trails (less than 8 foot wide) wherever bikes are permitted at their September 5th board meeting. Class 2 e-bike access to paved regional trails was also approved. Staff were directed to collect relevant data including bike volume and safety issues and provide a report one year from now.   This was done as a change to Ordinance 38 and not a pilot or trial.   Ahead of the meeting 154 public comments had been received with 33 supporting, 54 opposing, and 67 calling for a delay in making this change. Approximately 12 live public comments were made with a similar distribution in position.   The staff report and presentation was thorough and strongly supported the change.   It was noted that the MidPen study supported this decision despite MidPen taking a more limited access approach on their policy decision.   Director Coffey once again strongly supported this change on the merit of benefits of e-bike use to a variety of demographic users and the practicality of the district’s significant experience with e-bikes on natural surface trails already.

Discussion of the e-bike changes starts around 1:25:50 and runs to about 4:10

Trail Maintenance Basics Video Series – Arizona Trail Association 

If you’re looking for some trail maintenance basics then check out this short series from the Arizona Trail Association. Yes there are some differences between Arizona and the East Bay but the fundamentals are the same for brushing and drainage for sustainable trails. 

Brushing of the trail corridor keeps sight lines clear and promotes safety for all users. Properly functioning drainage protects watersheds minimizing erosion and helps keep the trail tread in good shape for users. Each video is less than 5 minutes. Here you go!

How did Joaquin Miller Park come to be?

There’s a historical record of a native American village in Trestle Glen, aka Indian Gulch. I’ve also read of one somewhere around the bottom of Palos Colorados. You would want to be near a waterway, and the way the Hayward Fault causes the steep hillside to meet a valley on the perpendicular makes for a good spot. So Palos Colorados has probably been there a long time. Amelia Sue Marshall’s East Bay History talks about this. Early resident Franklin Rhoda describes an Indian trail that Fremont followed over the shoulder of Redwood Peak, down what’s now Lincoln Avenue.

Francis Spring sold the property from 13 to Sequoia Bayview to Joaquin Miller in 1887. The land was completely bare of trees, just dirt and rock. Someone had to have dragged all those giant redwoods out. I’m fairly sure Cinderella, Chaparral and Castle Park were log chutes. There was a mill at the bottom of Palos Colorados,

Joaquin put in trails, like Bishops Walk, and he tried to tunnel through the ridge to get water from Palo Seco creek to his home.

When his widow sold the property to the city in 1917, Joaquin Miller Park was created. In 1924 the city finally got a bond measure passed and bought the parcel of “Smiths Reserve” from the Realty Syndicate, preserving the parcel from Redwood Peak to Sequoia Bayview, Castle Drive to Skyline Drive as Sequoia Mountain Park.

The Sequoia Bayview trail is on the boundary, likely getting its name from Sequoia Mountain Park. At some point in the 1950s the two parks were conjoined and called Joaquin Miller Park.

The Kiwanis built both versions of Sinawik, and the girl scout cabin. The Contra Costa Hills Club, under the direction of Harold French, built Sunset, and probably lots of other trails. Sydney Chown built many trails, including the “Piedmont trail,” which now has many other names, There were ranches near the top of the park owned by Sylva/Silva/Silver and Classen, and they certainly had roads and trails. French trail was an old wagon road. The paved access road in JMP is the old Skyline alignment. Bayview, on its way to Castle Park was probably built by the Realty Syndicate to showcase the property; there are perfectly spaced Monterey pines (or stumps) on the uphill side, just as there are near the West Ridge / Graham / Redwood Bowl junction. In 1947 aerial photographs you can see the state of the JMP/SMP trails. Portions of Sequoia Bayview (the ‘steps’ trail below the pump track) and Big Trees are the old Skyline alignment. Before Skyline was created in the 1920s, there was the “McNally road” along the ridge, at least to around where Roberts Park is today. People were coming up to Redwood Peak regularly, from the flats.
