The official shoreline map shows the Article IV shoreline environment designations (SEDs) that apply to each segment of the shoreline planning area under SMP jurisdiction. It does not necessarily identify or depict the precise lateral extent of shoreline jurisdiction or all associated wetlands. The lateral extent of the shoreline jurisdiction at the parcel level shall be determined on a case-by-case basis at the time a shoreline use/development is proposed. The actual extent of shoreline jurisdiction requires a site-specific evaluation to identify the location of the ordinary high water mark and any associated wetlands.
The county shall maintain a Geographic Information Systems database that depicts the coordinates for locating the upstream extent of shoreline jurisdiction (that is, the location where the mean annual stream flow is at least 20 cubic feet per second). The database shall also show the limits of the floodplain, floodway, and channel migration zones, and such information shall be used, along with site-specific information on the location of the ordinary high water mark and associated wetlands, to determine the lateral extent of shoreline jurisdiction on a parcel-by-parcel basis. The database shall be updated regularly as new information is made available and the public shall have access to the database upon request.
Appendix A, attached to the ordinance codified in this chapter, depicts the SEDs in two formats:
(1)
Official Shoreline Map. An overview map showing all of Jefferson County (image sized for large format printing).
(2)
A collection of 18 break-out maps at closer range to allow greater details (images sized for 11-inch by 17-inch printing). Western Jefferson County is depicted in a single break-out map (Map No. 18). Eastern Jefferson County is broken into separate images (Map Nos. 1 through 17) as shown in Appendix A of the ordinance codified in this chapter.
