EVALUATING EROSION RISK MITIGATION DUE TO FOREST RESTORATION TREATMENTS USING ALLUVIAL CHRONOLOGY AND HYDRAULIC MODELING

New Monitoring Report Complete: Schultz Creek is a major tributary of the Rio de Flag watershed of the City of Flagstaff, Arizona, which is being treated by the FWPP. This study used alluvial chronology to study the recent geologic history of Schultz Creek and hydraulic modeling to predict how peak flood flow magnitudes and stored sediment could be affected by severe wildfires and FWPP treatments in and adjacent to Flagstaff, Arizona.

Open Letter to the Community

As the Flagstaff Watershed Protection Project continues to move forward, Paul Summerfelt, FWPP Project Manager for the City of Flagstaff, would like to share an update on recent FWPP accomplishments and efforts currently underway to protect our community and surrounding forest.

Equestrian Project – Post Treatment Survey Results

Prior of implementation of the FWPP Equestrian Forest Management Project, residents in Equestrian Estates and University Heights adjacent to the project were mailed notice of the pending 400 acre project which occurred August-September 2014. This project, the first mechanical removals as part of the FWPP, was widely accepted and greatly appreciated by area residents who have recognized the necessity to conduct these much needed forest treatments to protect their neighborhoods and the greater Flagstaff community. Following completion of the project, a second letter with a survey was mailed to these residents asking for their opinion on the project and its benefits.

FWPP DEIS Summary Report

Alternatives 2 and 3 would have the greatest reduction in active crown fire potential: from approximately 57 percent of the project area under the No Action Alternative to 7 percent under Alternatives 2 and 3, compared to approximately 28 percent under Alternative 4. Alternatives 2 and 3 would also result in the greatest reduction in post-fire predicted peak discharge associated with a 100-year storm event (1 percent recurrence interval): 60 percent reduction for Alternatives 2 and 3 versus 30 percent reduction for Alternative 4 as compared to the No Action Alternative. All three action alternatives include a Forest Plan amendment to allow mechanized equipment for thinning on slopes greater than 40 percent (see Forest Plan Amendments in Chapter 2 and Appendix A for more information).

FWPP Draft Environmental Impact Statement (DEIS) Release

Based on input received on the Proposed Action released in April 2013, the US Forest Service (USFS) developed four treatment alternatives, which are analyzed and compared in the Draft Environmental Impact Statement (DEIS) which has been released for public comment July 3rd. The public is encouraged to provide feedback during the 45-day comment period ending August 18th. The USFS will use the comments received to develop the Final Environmental Impact Statement (FEIS) and draft Record of Decision (ROD); these will be published later this year.  Once the FEIS and draft decision are published, there will be a 45-day objection period for those who provided comments followed by a 45-day resolution period.  The final ROD, which will contain the final decision for treatment, is expected early next year (2015).

Two open houses are scheduled at the Flagstaff Aquaplex July 17th and 22nd from 5:00-7:30 PM to review the DEIS. The DEIS, along with a Reader’s Guide, a Map Packet and other supporting information can be found online at www.fs.usda.gov/goto/FWPP.

 

 

FWPP Biannual Report (Jan.-June 2014)

In the November 2012 election, City voters overwhelmingly approved (74%) a $10 million dollar bond to fund the Flagstaff Watershed Protection Project (FWPP). Forest treatments will occur primarily on federal lands outside of the City, as well as on City and State lands, within City limits; all treatments are designed to reduce the risk of severe wildfire and subsequent post-fire flooding in the Rio de Flag (Dry Lake Hills) and Lake Mary watersheds. This report highlights significant accomplishments in the first half of 2014.
