Technical Results
Education
Education efforts included lot-by-lot soil tests with fertilization
recommendations, meetings with the property owners’ association,
one-on-one discussions and demonstrations of appropriate fertilizer
application methods. The education efforts were not as successful
as anticipated. Analysis of yearly survey results of all residents
in the study watersheds indicated that, in general, residents of
all three watersheds across several years of study showed no differences
in behaviors such as lawn care (i.e., watering, fertilization), pet
waste disposal and car washing. One example result is shown below
(Table 1). However, some changes were found: more residents of the
LID subdivision composted their leaves than in the other two subdivisions
(Table 2).
More results can be found in the final report.

who fertilize their lawn, grouped by study area, 2004. No significant
difference among groups was found.

Table 2. Percentage of residents
who compost their leaves, grouped by study area, 2004. Significantly
more LID residents composted their leaves than the other two
groups.
