MEMORANDUM
DATE: July 12, 2016
TO: Supervisor Scott Haggerty, Chair
Supervisor Nate Miley, Member
TRANSPORTATION AND PLANNING COMMITTEE
FROM: Daniel Woldesenbet, Ph.D., P.E.
Director of Public Works
SUBJECT: TEMPORARY ROAD CLOSURE AND DETOUR OF PALOMARES ROAD IN
CONNECTION WITH THE ALAMEDA COUNTY RESOURCE
CONSERVATION DISTRICT’S STONYBROOK CREEK CROSSINGS AND
FISH PASSAGE IMPROVEMENT PROJECT
SUMMARY:
The Stonybrook Creek Crossings and Fish Passage Improvement Project (Project) is a
collaborative project between the Alameda County Resource Conservation District (RCD) and
Alameda County Public Works Agency (PWA). The Project is located within and immediately
adjacent to the Palomares Road right of way, a County roadway, at mile marker 8.60 to 8.75 to
the north of Niles Canyon Road.
The Project includes restoration of the Stonybrook Creek banks, removal of fallen boulders from
culvert entrance, restoring culvert water passage capacity, creating fish passage step ponds, and
replacement of an old bridge with a new and seismically competent structure. The replacement
bridge will remove the existing barriers to migrating steelhead trout in Stonybrook Creek.
In order to implement the project this summer, a full road closure is necessary during the
construction period. Construction will start August 3 and will result in an estimated 12 weeks of
full road closure, ending October 26. Eliminating a temporary crossing will speed up the work
and reduce the anticipated construction window.
DISCUSSION:
Project Status
Phase 1: Downstream Crossing, Mile Marker 8.75
Creek banks restoration, removal of fallen boulders from the lower culvert crossing, culvert
modification and construction of fish passage at the creek bed was completed in 2015.
Phase 2: Upstream Crossing, Mile Marker 8.60
In 2016, construction work includes demolition and removal of the existing concrete and
masonry bridge including wingwalls and related structure, re-grading of the channel in the
vicinity of the crossing, restoration of the creek embankments and bed, construction of new,
custom modular bridge, including wingwalls and related structures, and restoration of the
existing roadway and related facilities.
The final new, custom precast bridge design was approved by the RCD, PWA and the RCD
engineer on April 20, 2016. Based on the final design, it came to our attention that a temporary
bridge option, considered at earlier periods, was no longer feasible. As such, the RCD has been
DocuSign Envelope ID: 4B2C3170-BD38-4F2D-8DBC-2A224EF30A80
seeking the alternative of a full road closure. RCD has been coordinating with PWA, Alameda
County Fire Department, and other stakeholders to minimize the impact of a full road closure.
Outreach Efforts
The RCD, National Resource Conservation District (NRCS), and PWA met with Supervisor
Valle and Supervisor Haggerty on June 30th
to discuss the options available and timeline for
construction of the project. A public meeting will be held in conjunction with the regularly
scheduled Sunol Advisory Committee Meeting on July 20th
at the Sunol Glen Elementary
School. The RCD has outreached directly with several bicycle organizations including Bike East
Bay, Fremont Freewheelers and other bicycle clubs.
With your concurrence, the PWA will forward a Resolution requesting the full Board to approve
the road closure and detours as requested by the Alameda County Resource Conservation
District.

ROAD CLOSURE NOTICE
PALOMARES ROAD
SUNOL GLEN ELEMENTARY SCHOOL CAFETERIA A portion of Palomares Road will be closed for an extended period of time beginning August 3 in order to complete a bridge replacement over Stonybrook Creek. During construction, Palomares Road between mile post 8.70 and 8.50 will be closed to thru traffic through October 26. This meeting will discuss the closure and anticipated road delays. The closure will block traffic access along Palomares Road accessed from Niles Canyon Road/Hwy 84. Drivers, bicyclists and pedestrians will be unable to use Palomares Road to travel between Niles Canyon/Hwy 84 and Hwy 580 for the duration of the work and will need to take alternative routes. Residents past mile post 8.50 will only be able to access via Palomares Road from Hwy 580. Emergency responders and other service providers have been notified and will be prepared to provide services during the road closure. A Frequently Asked Questions sheet and map is included for your reference. For more information, please visit the Alameda County Resource Conservation District’s website at www.acrcd.org/NewsEvents.aspx. Updates will also be listed on the Alameda County Public Works website at www.acgov.org/pwa.
For more information please contact Leslie Koenig at (925) 371-0154 ext 115 or leslie.koenig@acrcd.org.

Palomares Road Temporary Closure Frequently Asked Questions
Q: Why is Palomares Road being improved? A: Palomares Road includes a narrow section of roadway which sits over an aging masonry lined culvert within the habitat-sensitive Stonybrook Creek that was built in 1938. This crossing has been subject to erosion that has created an approximately 10 foot drop in the channel resulting in considerable undercutting of the area compromising the culvert stability. In addition to structural concerns, the culvert serves as a barrier to fish passage within the stream. This project will improve the culvert and road to ensure that is safe for the traveling public now and in the future.
Q: What is included in this project? A: The new improvement include demolition and removal of the existing concrete and masonry bridge, re-grading of the channel in the vicinity of the crossing, restoration of the creek embankments and bed, construction of new, custom modular bridge, including wingwalls and related structures, and restoration of the existing roadway and related facilities. This increased size will allow a more stable flow of water, stop the ongoing deterioration within the stream, and will lessen the possibility of emergency road closures in the future.
Q: What will the construction mean for the traveling public? A: The culvert construction project will require the closure of Palomares Road between postmiles 8.50 and 8.70. Drivers, bicyclists, and pedestrians will be unable to use Palomares Road to travel between Niles Canyon/Hwy 84 and Hwy 580. The traveling public will need to take alternate routes.
Q: When will construction begin and end? A: The work is set to begin on August 3, 2016. It is anticipated that the culvert and replacement roadway construction will be complete and the road will be reopened on October 27, 2016. The construction period is limited because the creek is an environmentally sensitive habitat. Construction can only take place in dry periods to minimize any potential impacts to the environment or wildlife.
Q: Why couldn’t a by-pass road, or a phased project without road closures, be built? Was a road closure the only alternative? A: All construction alternatives were explored before determining that this approach was the least impactful of the alternatives. The constraints of the site, the habitat, and environmental sensitivity of the area made full road closure the only alternative. Through closure of the road the construction period will actually be shorter and will provide a safer completed project. The stretch of the road where this culvert is placed is a highly constrained area and in order to maintain public safety the road closure is necessary.
Q: What about impacts to residents? How will emergency response be coordinated? A: We understand that this road closure will be inconvenient for residents who use this segment of roadway. However, road safety is paramount and this improvement will ensure that this segment of roadway is safe for future travel. Emergency responders from all of the affected jurisdictions have coordinated a response plan for this time period.
Q: What has been done to notify residents about this project? A: A public meeting will be held on July 20, 2016 at 6:30pm at Sunol Glen Elementary School Cafeteria to outreach the closure to residents and interested public. Residents will be updated on the Alameda County Resource Conservation District and Alameda County Public Works websites, and signage will be place in the affected areas to notify them of the road closure.
Q: How can I learn more and stay informed? A: The Alameda County Resource Conservation District’s webpage, http://www.acrcd.org/NewsEvents.aspx and Alameda County Public Works webpage, www.acgov.org/pwa, will be updated regularly. Residents may also sign up to receive email or text message updates from the Alameda County Public Works Department.
