Title: Watershed Analysis


1
Watershed Analysis
  • Presented to the
  • Washington State Forest Practices Board
  • By Mary McDonald and Marc Engel
  • Department of Natural Resources, Forest Practices
    Division
  • Special Meeting of the Forest Practices Board,
  • March 31, 2009

2
Watershed Analysis
  • During 2008 the Board directed staff to perform
    forest practices program review of Watershed
    Analysis and Forest Practices Application Review
    and Approval Processes

3
Watershed Analysis PresentationTwo Parts
  • Forest Practices Application (FPA) review
  • Findings
  • Actions initiated by Forest Practices Program
  • Review of Watershed Analysis statutes and rules
  • Findings
  • Staff recommendations

4
FPA Review
  • What is a Watershed Administrative Unit (WAU)?
  • Assessments of DNR-identified WAUs
  • WAUs usually between 10,000 and 50,000 acres
  • WAUs defined by hydrology and geomorphology
  • NOTE there are 846 WAUs of which 466 are under
    forest practices jurisdiction.

5
FPA Review
  • What is Watershed Analysis?
  • Biological and physical assessment of a watershed
  • Looks at cumulative effects of forest practices
    on resources addressed by Forest Practices Act
    and rules
  • Includes evaluation modules

6
FPA Review
  • Watershed Analysis Modules
  • Mass Wasting
  • Surface erosion
  • Hydrologic change
  • Stream channel
  • Fish habitat
  • Public works
  • Cultural resources

7
FPA Review
  • Watershed Analysis
  • All Watershed Analysis subject to SEPA review and
    DNR approval
  • Forest practices activities incorporating
    prescriptions are not subject to SEPA review for
    the specific issue covered

8
FPA Review
  • Mass Wasting Prescriptions
  • Harvesting
  • No ground system logging
  • Cable logging permitted with partial suspension
  • Road Building
  • No new road construction on to scree slopes

9
Watershed Analysis Mass Wasting Prescriptions in
FPAs
  • WAC 222-16-050(1)(d)(iii) directs that certain
    FPAs are not to be classified as Class IV-Special
    for potentially unstable slopes or landforms if 3
    criteria apply
  • within a WAU with an approved watershed analysis
    and
  • conducted according to an approved watershed
    analysis prescription and
  • prescription is specific to the site or
    situation, as opposed to a prescription that
    calls for additional analysis

10
Review Findings
  • The three criteria are not always correctly
    applied
  • Some FPAs are being classified as Class III
    rather than Class IV-Special based on watershed
    analysis prescriptions that are not specific or
    call for additional analysis.

11
Review Findings
  • Specific vs. Non-specific prescriptions
  • Specific Prescriptions
  • No road construction except where slopes are less
    than 40 and are stable
  • Non specific prescriptions/additional analysis
  • Proposed harvest unit shall be reviewed under
    direction of a qualified geologist

12
Review Findings
  • 21 of mass wasting prescriptions were determined
    by FP to be specific
  • If FPA has a WA and is proposing an activity on
    an unstable landform that is utilizing
    nonspecific mass wasting prescriptions, the FPA
    is a Class IV-Special

13
Actions Initiated
  • Watershed Analysis Worksheet required
  • Guidance Spreadsheet identifying specific
    prescriptions
  • Review/training of region/division staff
  • Geologist review sample to verify specific
    prescriptions

14
Actions Initiated
  • Resources regarding mass wasting prescriptions
  • Programmatic FPA review and documentation
    expectations implemented
  • Master Forest Practices Application log sheets
    used by all regions
  • Interactions with DOT concerning FPAs

15
Review of Watershed Analysis Statutes and Rules
  • The Board asked staff to recommendation how to
    eliminate Watershed Analysis. Staff found
  • Has been treated as legacy under forests and fish
    rules
  • Training is not being offered and as a result,
    there are no certified experts
  • 21 of mass wasting prescriptions are specific

16
Watershed analysis modules
  • Mass Wasting
  • Surface erosion
  • Hydrologic change
  • Stream channel
  • Fish habitat
  • Public works
  • Cultural resources

17
Class IV-Special Trigger for Unstable Slopes
  • WAC 222-16-050(1)(d) Timber harvest, or
    construction of roads, landings, gravel pits,
    rock quarries, or spoil disposal areas, on
    potentially unstable slopes or landforms (with)
    the potential to deliver sediment or debris to a
    public resource or that has the potential to
    threaten public safety

18
Exemption from Class IV-Special
  • (iii) An application (is) not classified as Class
    IV-Special for potentially unstable slopes or
    landforms if     (A) The proposed forest
    practice is located within a WAU that is subject
    to an approved watershed analysis     (B) The
    forest practices are to be conducted in
    accordance with an approved prescription from the
    watershed analysis (or as modified through the
    five-year review process) and     (C) The
    applicable prescription is specific to the site
    or situation, as opposed to a prescription that
    calls for additional analysis. The need for an
    expert to determine whether the site contains
    specific landforms will not be considered
    "additional analysis," as long as specific
    prescriptions are established for such landforms.

19
Three ways change to the Watershed Analysis rules
  • Legislation
  • Courts
  • Adaptive management

20
Staff Recommendation
  • Board direct staff to prepare
  • A mass wasting adaptive management proposal and
  • Answers to the questions listed in Part 3.1,
    Proposal Initiation of Board Manual Section 22,
    Guidelines for the Adaptive Management Program.

21
Staff Recommendation
  • Proposal is to change the rules through the
    Adaptive Management program to
  • Remove the exemption for mass wasting
    prescriptions from the definition of Class
    IV-Special in WAC 222-16-050 and to
  • Add language in WAC 222-22-070 establishing that
    the current rules supersede all mass wasting
    prescriptions.

22
Staff Recommendation
  • Board directs staff to present for review the
    mass wasting adaptive management proposal at
    their May 20th meeting.
  • With Board approval the proposal will be
    forwarded to the Administrator to initiate
    review under Part 3 of the Adaptive Management
    Program.
