Continued community control of land
use decisions, but science-based
planning must be employed;
Site plan reviews performed by
watershed council
Use geologic and vulnerability
maps and the information gathered
from environmental site investigations
to identify the best places for
nonstructural measures and source
control. Incorporate parcel-level
science-based planning into 319
grants
Use geologic and vulnerability
maps to characterize water flows
and the original landscape, and
with these as a guide, identify
land areas within the watershed
for preservation. Brownfield
redevelopment must rely on the
science used for the remediation;
these parcels should be considered
active landscape components.
Use the outcomes from the science-based
parcel-scale planning to guide BMP
use, and as input to the watershed-wide
monitoring efforts. Involve more
environmental scientists in the
parcel-scale planning process.
Must be ongoing and consistent.
Publish all monitoring results.
Include watershed management in
K-12 school curricula. Update all
parcel-scale planning documents to
include watershed implications.

releases are more likely to occur (Chapters 6 and 14). Together, this body of information
can help characterize areas under consideration for development, and also be used to
locate common source and nonpoint source locations (16.3.1). To help increase the use of
nonstructural controls at the watershed scale, science-based parcel-scale site plan imple-
mentations with nonstructural controls can be included as part of Clean Water Act Section
319 watershed planning grants.
16.4.3 Land and Water Management
More efficient and effective land preservation is achieved when land and water manage-
ment are combined. The information provided by geologic and vulnerability maps per-
mits relatively easy land and water management at the parcel scale, where the property is
usually owned by one party and there is little red tape. Mimicking this decision-making
process at broader scales means limiting the number of land and water management
