Floodway Issue
1/7/2007	ISYS QUERY FLOODWAY	One of the most contentious issues in 2007-2008 will be the placement of a floodway in the lower valley in accordance with the NFIP regulations. This documents represents a small sampling of historic documents that address this issue. As the documents clearly show a floodway designation was in fact made in the 1980's however was never enforced.
5/27/2007	1981-1984 FEMA-BFE Flood Research	Compilation of articles describing the FEMA flood insurance base flood elevation and floodway determination made by FEMA in 1984.



5/9/1980	Floodway Meetings with Skagit County, Burlington, Hamilton, and Lyman	Split floodways, equal conveyance floodways, growth in the City of Burlington, floodway between Burlington and Sterling Hill all were discussed at these meetings.

9/8/1980	MFR re meeting in Skagit County re Floodway Designations	MFR documents 9/3/80 meeting in Skagit County re Floodway Designations. Impacts of filling in Burlington on Port property discussed. Burlington worried about “no-growth mandate.” Suggestion was made to let the Flood Control Advisory Committee come up with floodway designation. Corps concerned about filling around the Sterling Hill area. Burlington not sensitive to the filling problem.
12/5/1980	Ltr to Corps from FEMA re Floodway Designations	Letter states probable failure points (PFP) not reliable for designating floodways. Decision made to use 1972 overtopping of entire levee system.
12/10/1980	MFR re Floodway Designation Methodology	MFR documents discussions between Corps, FEMA and Skagit County re proper method of designating floodways. 1972 study vs. 1000 foot setback from levees discussed.
3/25/1981	SVH Article re floodway designation devastation	Skagit Valley Herald article which quotes FEMA official that if local government cannot agree on floodway designation then the Federal government would do it for them. FEMA would have to use "equal conveyance" method which would "devastate" local economy. Once floodway is picked dike improvements and dike construction would be prohibited.
5/27/1981	MFR re Floodway Designation help from HEC	MFR discusses “density” floodway study being financed by FEMA and getting help from HEC in California on floodway problem for lower Skagit Basin.
6/9/1981	MFR re Floodway Designations	MFR documents discussions between Corps and FEMA re floodway designations. Equal conveyance method in lower valley politically unacceptable. FEMA not considering lost storage effects in FIS. Density floodways considered. 40 acre lot size in County could accomplish same thing as density floodway. Corps needed more detailed topography. Potential development between Burlington and Mt. Vernon could eliminate floodway and cause damming effect upstream. Suggested using “C-10” language in FIS.
7/8/1981	FEMA letter to Art Day	Letter discusses building restrictions in floodways.
11/10/1981	BOC Minutes re floodway designations & dam storage	The minutes reflect the discussion that took place between the BOC and the flood control committee re the 1981 flood control committee report. Most important is the documentation that PSPL had told the flood committee that the Baker Dams already provided 100 year protection.
3/24/1982	FEMA letter to Burlington	FEMA open to discussion of "density floodway". Local people thought keeping open 25% of parcel of property would be enough. FEMA refers to amount as "admittedly arbitrary" and "considerably understates" amount of land needed to pass 100 year flood.
4/2/1982	Memorandum for Record re Dames & Moore Study	Floodways should be delineated on FEMA maps as showing only the main channel and the levees on the inside toe (the protected side) of the levees. Dames & Moore to determine density floodway amount of land to be set aside for 100 yr flood.
12/1982	Dames & Moore Report	100 year flood determined to be 240,000 cfs at Sedro-Woolley. 110,000 cfs assumed to stay in channel. 130,000 cfs assumed to flow overland. Assumed 86,000 cfs flowing to Padilla Bay and 44,000 cfs flowing to Skagit Bay via the Samish basin. I-5 will ultimately be overtopped. Used Mannings "n" values of .045 to .06. Recommended 10% of floodplain could be developed using density floodway method until flood waters would be raised 1 foot.
8/22/1983	FEMA letter re floodway designation of Gages Slough	This letter discusses why FEMA felt it could not designate Gages Slough as a floodway. Cascade Mall hydraulic study could not be supported by any scientific or technical data. Section 60.3c would be part of local ordinances which would require hydraulic analysis of fill in the Burlington area.
12/15/1983	FEMA letter re development restrictions	FEMA informs Dept of Ecology that since a regulatory floodway had not been designated that 60.3(c)(10) would have to be enforced before local or state permits could be issued for building permits.
2/1/1984	FEMA letter re denial of appeal filed on Burlington FIS	This letter explains why the appeal of the Burlington FIS was denied by FEMA. Regulations only require FEMA to use available topographic data. Lands within and including the Skagit River levees were designated as floodways. Unlikely that historical depth of floodwaters would be repeated.
11/08/1984	Transcript of Burlington City Council Meeting November 8, 1984	“Lastly there is the FLOODWAY which in the case of Burlington is only the area that runs landward of the dike by fifty feet. When you’re landward of the dike and your looking towards the river essentially nothing can be built from that distance to the river.” (Steve Ladd, City Planner)
2/2007	Skagit Floodway Mitigation and Hamilton Relocation Program Fact Sheet	Fact sheet explaining the legal requirements and many economic benefits of relocating Hamilton out of the floodplain, "FEMA reports that losses to date for the 100 flood affected properties in Hamilton alone cost public programs and the NFIP close to $20 million."
5/24/2007	TV10: May 24, 2007 Town Hall Meeting - FEMA Flood Mapping: How Will It Affect You?	City of Mount Vernon TV10 video hosted on Google Video of May 24, 2007 town hall meeting convened by the Mount Vernon and Burlington Chambers of Commerce. The City of Burlington, City of Mount Vernon, FEMA and county commissioner candidate Don Gordon all spoke at the meeting. There is 12 seconds of silence before the movie starts.
5/21/2007	Common Questions & Answers Pertaining to the Skagit River FIS (Handout at the May 24, 2007 Town Hall Meeting)	FEMA Q&A regarding the Skagit County Flood Insurance Study - includes a section on floodways. [Skagit County Government also has a page about this.]
5/24/2007	Burlington Chamber of Commerce Agenda and Handout for Town Hall Meeting	Agenda for "FEMA Flood Mapping: How Will It Affect You?" and handout Flood Hazard Mitigation - The Future of The Skagit Valley. Includes discussion about floodway issues.
8/28/2007	Work Session - Restrictions on Development on Cockreham Island and Other Areas in the ‘Floodway’	Skagit County Public Works explains to the public through Skagit 21 the policy implications and consequences of the floodway designation on building owners.
10/9/2007	Resolution R20070501: A Resolution to Safeguard the Public Welfare by Protecting Property, Life and the Environment in the Floodway	Skagit County Commissioners "hereby orders and direct that the public health, safety and general welfare be safeguarded, and that construction or development within the floodways of the Skagit River be prohibited or restricted to the maximum extent allowed by County".
05/21/2009	Federal Emergency Management Agency (FEMA)	“FEMA did not define a floodway for Skagit River delta communities. The City of Burlington must therefore administer their floodplain ordinance in accordance with 44 CFR 60.3 (c) (10) which states: "no new construction, substantial improvements, or other development (including fill) shall be permitted within Zones Al-30 on the community's FIRM unless it is demonstrated that the cumulative effect of the proposed development, when combined with all other existing and anticipated development will not increase the water surface elevation of the base flood more than one foot at any point within the community.”
