features from each of the LID categories.
a. Consider incorporating “conservation designs” that
focus on preserving open space, such as clustered
development, reducing pavement and creating shared
driveways.
b. Consider incorporating “infiltration practices” that focus
on engineering structures or landscape features that are
designed to capture and infiltrate runoff such as basins
and rain gardens.
c. Consider incorporating “runoff storage practices” that
capture, store and reuse stormwater runoff including
rain barrels, green roofs and depressional storage in
landscape islands.
d. Consider incorporating “runoff conveyance practices”
that route excess runoff through swales and long flow
paths in landscaped areas with minimal piping and hard
surfaces, while maintaining traditional flow patterns of
high flow events offsite.
e. Consider incorporating “filtration practices” that direct
stormwater runoff to bioretention areas, rain gardens,
vegetated swales and filter strips that capture pollutants
from the runoff.
f. Consider incorporating “low impact landscaping”
that reduces impervious surfaces, increases infiltration
potential and improves the aesthetics of a site such as
native plants, re/planting turf areas and amending soil to
improve infiltration.
and features to minimize impacts to the municipal
stormwater system and area watersheds.
a. Incorporate permeable surfaces into the overall site
design on small surface areas such as pathways, rather
than parking lots or large areas in the right-of-way.
b. Include a stormwater management feature - such as a
bioretention swale or another planted paving system,
greenroofs and rain gardens/barrels/cisterns, as a site
amenity or landscape feature.
c. Utilize native plants (Appendix F in the LID manual) that
do not require additional irrigation beyond the initial
plant establishment period.
