Brief Summary of Bill |
|
Hearing Date: 1/21/08
Staff: Jason Callahan (786-7117).
Background:
Before beginning a construction project, a person must obtain a hydraulic project approval (HPA)
for any project that will use, divert, obstruct, or change the natural flow or bed of any of the salt
or fresh waters of the state. HPAs are issued by the Department of Fish and Wildlife (WDFW) to
ensure the proper protection of fish life [RCW 77.55.021].
Included in the scope of the HPA permitting program are streambank stabilization projects. Most
HPAs can be modified by the WDFW if conditions change after being issued. However, for
streambank stabilization projects, the WDFW can only modify the approval if the WDFW can
show that changing conditions warrant the modification in order to protect fish life [RCW
77.55.021(6)].
Summary of Bill:
The WDFW is required to identify at least three engineered model bank stabilization methods
that would provide adequate protection for fish life while protecting riparian property from
floods. The model methods are to be designed so that a riparian landowner can choose from
among them when commencing a bank stabilization project to protect his or her property from
flooding. The methods must also include general engineering and design criteria.
The WDFW must include in the model methods developed one that utilizes only rock products,
one that utilizes only woody debris and other organic matter, and one that utilizes both rock and
woody debris.
The information provided by the WDFW must include directions as to the appropriate project
dimensions for the model in relation to the 100-year flood level, as well as suitable riparian
location and proximity in relation to the stream bed. Additional details must be included that
provide the landowner with comparative information relating to materials, as well as engineering
costs.
A landowner utilizing one of the model projects is still required to obtain an HPA. Landowners
not choosing to utilize a model project may still proceed with other methods.
Appropriation: None.
Fiscal Note: Available.
Effective Date: The bill takes effect 90 days after adjournment of session in which bill is passed.
