4.1.8 Flood History
Identification of flood occurrence by community was defined from the flood events inventory. A
link was established between community name and flood occurrence and LGP number and
flood occurrence. Upon review of the resultant data it was determined that an appropriate
reflection of flood history is captured through the LGP number and flood occurrence association.
Prioritization weighting will be based on the number of flood events documented for a LGP
number divided by 10.
4.1.9 Flood Damages Estimates
Flood damage estimates (reported damage and DFAA damage estimates) by community were
defined from the flood events inventory. As noted in the flood inventory section of this report
very little flood damage estimate data is available. As such, priority weighting was assigned
simply as “1” if damage estimates (either) were available and “0” if neither were available.
4.1.10 Watershed Runoff Potential
Soils
The Soil Survey Reports for Newfoundland and Labrador available from Agriculture and Agri-
Food Canada 27 formed the basis for identification of dominant soils in watersheds. The
Drainage attribute (associated with the soils data) was interpreted as hydrologic soil classes
(see Table 4-4). The areas associated with each hydrologic soil class were abstracted on a
watershed basis, based on the National Frameworks Data, Hydrology and Drainage Areas, and
the dominant soil class identified.
The prioritization weighting will reflect the dominant hydrologic soil group as follows
27 Soils data references the Soil Survey Reports for Newfoundland and Labrador available from
Agriculture and Agri-Food Canada from their website at
http://sis.agr.gc.ca/cansis/publications/surveys/nf/index.html. The soil survey reports, while not extensive,
is believed to be the best source of soil information available. See Figure 6-3 for a map of the soil data.
