SHORELINE ALTERATIONS ANALYSIS RESULTS and EXAMPLES OF SHORELINE ALTERATIONS
ANALYSIS RESULTS
This draft analysis evaluates the degree to which 10 ecological processes
along shorelines of the state are altered. Processes evaluated include sediment,
large woody debris, wave
energy, light energy, nutrients (phosphorus
and nitrogen), pathogens,
tidal influences, hydrologic
cycle and toxins. The overall quality (low to
high) of each shoreline reach was determined according to the degree to which
these processes were altered. A full description of this analysis and its results
can be found in the draft King County
Shorelines Technical Appendix and the results for specific shoreline reaches
can be viewed with King County's Shoreline Mapping
Lookup tool.
SHORELINE JURISDICTION
Shorelines of the State include all marine shorelines, lakes greater than 20
acres, and rivers and streams with 20 cubic feet per second (cfs) mean annual
flow or greater. The shoreline jurisdiction includes these water bodies and
shorelands. Shorelands are defined as those areas extending landward for two
hundred feet from the ordinary high water mark, floodways and contiguous floodplain
areas landward two hundred feet from such floodways, and all associated wetlands
and river deltas. King County currently includes the zero-rise floodway, essentially
the 100-year floodplain, in its shoreline jurisdiction.
The updated spatial data of the shoreline jurisdiction was developed based on
State direction to include all qualifying shorelines on federal lands (these
were not previously included) and to use new information from a 1998 US Geological
Survey study to identify the location of 20 cubic feet per second flow points
on streams (these new points are higher up in the watershed than most current
points). Further, lakes were reevaluated in relation to the 20-acre threshold
given the availability of new data about lake size.
Data Sources: Existing and proposed jurisdictional areas from King County/DOE (3/06), Shoreline of State Significance from WDOE, (8/01). King County standard datasets used for county boundary ("kingco", 2004), roads ("kcsn", 3/06), (water bodies ("wtrbdy", 8/06), streams ("wtrcrs", 2002), potential annexation areas (3/06), cities ("citymast", 3/06), associated floodplains ("fldplain", 3/06).
SHORELINES OF STATEWIDE SIGNFICANCE
The following water bodies and shoreland areas are currently identified
as Shorelines of the Statewide Significance in the King County Shoreline Master
Program:
- Those areas of Puget Sound and adjacent salt waters and the Strait of Juan de Fuca between the ordinary high water mark and the line of extreme low tide as follows:
- Nisqually Delta -- from DeWolf Bight to Tatsolo Point,
- Birch Bay -- from Point Whitehorn to Birch Point,
- Hood Canal -- from Tala Point to Foulweather Bluff,
- Skagit Bay and adjacent area -- from Brown Point to Yokeko Point, and
- Padilla Bay -- from March Point to William Point;
- Those areas of Puget Sound and the Strait of Juan de Fuca and adjacent salt waters north to the Canadian line and lying seaward from the line of extreme low tide;
- Those lakes, whether natural, artificial, or a combination thereof, with a surface acreage of 1,000 acres or more measured at the ordinary high water mark;
- Those natural rivers or segments thereof west of the crest of the Cascade range downstream of a point where the mean annual flow is measured at 1,000 cubic feet per second or more;
- Those shorelands associated with the water bodies above.

*Note: This data presents generalized information about the location of archaeological
sites along unincorporated King County shorelines; these sites are not mapped.
RCW 42.17.310 makes archaeological site location information exempt from public
release in order to diminish the risk that sites will be vandalized or looted.
It is illegal to knowingly disturb, remove or sell archaeological resources
on public or private lands without a state-issued permit (27.44 RCW, 27.53 RCW).
For more information about these sites, please contact the King County Historic
Preservation Program.

PUBLIC ACCESS GAPS AND OPPORTUNITIES
The following draft criteria were used to identify gaps in formal shoreline
public access and recreation. Formal public access and recreation are those
where access is specifically allowed and managed by a public agency. Identifying
gaps will help to identify and prioritize public access opportunities that could
be established as part of the Shoreline Master Program Public Access Plan. Gaps
include shoreline areas where there is:
- a notable geographic absence in public access opportunities;
- a notable absence in type of public access opportunities (visual, physical, or type of facility);
- informal access and use of sites that confirms demand; and/or
- population concentrated in area or otherwise known demand for access at the site.
Also considered in identifying public access gaps were existing public access plans. Plans considered include Public Boating and Fishing Access to the Cedar River (http://dnr.metrokc.gov/wlr/watersheds/cedrLKWA/cedar-river-public-access.htm, October 2006)) and Middle Fork of the Snoqualmie River Valley Phase II -- River Corridor Public Use Concept (September 1997).
Data Sources include: Boat launch, dock/pier, public street ends and swimming beaches from "WaterAccessMaster_13Jul06.prj" developed by King County DNRP staff, last updated on 11/15/06.
