4. Aerial Photography:
WALSH will procure all aerial photo.p aphy from Intrasean:h, Inc. to ensure accurate
referencing of aerial photography to existing,topographic Lase mapping. The aerials will
be obtained from two distinct points in time in order to sho A! the vegetation cover and
conditions of the site both prior to, and following the"Mudfest". Specifically, aerial
photos will be sought in digital format From 1995 (i.e.,the date of the original
topographic mapping and prior to the":Mudfest"); as well as a new photograph in
October 20W(i.e., post"Mudfest"). Tie post "Mudfest" aerial photo will be Flown, and
photo-rectified by,Intrasearch.
5. Baseline Condition and Impact Assessment
Accurate documentation of baseline (i.v.,pre-d sturbance)conditions, followed by impact
assessment(i.e., quantification of extent of disturbance)is essential for designs purposes.
WALSH will perform these tasks utiliz.ng office and field methodologies.
Office Level Assessment- The impac:area will be digitizec from the post"Mucifes:t"
aerial phow (October 2000)and overlaid on the pm-disturbitnce aerial photo(1995)and
Elie topographic base map (1995). The overlay data will illustrate the accurate limits of
disturbance, as well as pre-disturbance distribution and extent of vegetation communities,
topography, and drainage patterns.
Field Level Assessment:-The photo overlay method referenced above is highly accurate.
However,WALSH proposes to confirm and refine the accuracy of this method with
accurate field measurements. In order D)produce exact limits of disturbance and reduce
the probability for measurement errors, WALSH proposes to use a Global Positioning
System (GPS)device to field survey the exact disturbance limits resulting from the
"Mudfest". During the GPS survey,fluorescent pin flags will be inserted into the ground
to document turning points and define the impact limits in the field.These pin flags will
also serve to assist the restoration conshuction crew in the field.
Photo Documentation—WALSH will take extensive photographs of the site and
"Mudfest"impact arras during the Field Level Assessment. These photos will be taken
from OPS data points and assigned directional and descriptive information.
6. Threatened and Endangered Species Data:
WALSH will acquire best available data to asce lain the prer.ence or absence of
"threatened"and"endangered" species (e.g., Borcai Toad) and the limits of their habitat.
If T&5 species habitat is documented to be pres!nt within the disturbed area. then Calais
