11.4 Western Lake Erie Protection Strategy
The proposed page layout for the Western Lake Erie protection strategy maps uses
elements from the Central Puget Sound protection strategy maps (Northwest Area
Committee
2007
) and the Snohomish River GRP. The index map provides a small
scale (large area) overview of the area of responsibility of the area committee with
links or references to pages containing response strategies. The western basin of
Lake Erie covers a fairly large area. An index map is necessary to give responders
an overview of the area and the relative location of each protection strategy. The
map contains standard base map layers appropriate to the scale with callouts for
each protection strategy within the Western Lake Erie Area Committee's AOR.
Each of the callouts on the Western Lake Erie Protection Strategy Index Map is an
existing protection strategy found in the Western Lake Erie Plan. Where there is no
data in the existing strategy, the new data fields are left blank. The missing data will
be filled in as protection strategy updates are completed. The final map when
published as a .pdf will have links from the index map to each protection strategy.
Where there are multiple strategies within a small area, such as the Maumee River
in the Port of Toledo or the River Raisin in Monroe, MI, the link will be to a sub-
index map. Like the larger index map, the sub-index map contains links to protec-
tion strategy pages.

reflect the proposed protection strategy map design for the
Sun Oil docks on the Maumee River. Existing data from the 1998 edition of the
Western Lake Erie Area Plan are the basis for the proposed protection strategy
maps. There has been no data added to the strategies. Where there are numerous
strategies within a limited area, a local index map may be necessary. In the western
Lake Erie basin, rivers, commercial waterways and harbors may require a local
index map. Each protection strategy noted on the local index map then has its
own two page strategy, documenting steps to be taken and resources required by
responders to execute the pre-planned strategy at that location. The protection
strategy pages are designed to allow adaptations to local conditions. For instance,
collection points that are capable of accommodating collection and removal of
spilled product whether the flow direction is up river (toward the head of the river)
or down river (toward Lake Erie). Protection strategies that can accommodate
bi-directional flow have notations made to that effect.
There are standard data fields found in the same location on the front/back page
set. The front page (or page 1 if not printed front/back) of the strategy contains a map
that consists of base map layers and an orthophotograph of sufficient spatial resolu-
tion as to be able to discern details on the ground, typically one foot to one meter per
pixel spatial resolution. This map should be large enough (small scale) to provide
responders with an idea what surrounds the area to be protected and an idea of how to
get there. It also provides visual information about the general configuration of the
boom used in the protection strategy and where the collection point may be.
The reverse side of the map (or page 2 if not front/back) contains a larger scale
map of the collection point, pertinent boom anchor points and if appropriate a detail
