Does not compute volume
reduction for some BMPs, including
cisterns and tree trenches.
CivilStorm has an engineering library
with many different types of BMPs
to choose from. This list changes as
new information becomes available.

Includes simple calculator for rain
gardens.
Computes volume reduction for
trees, only.
Though developed for HSPF, the
USEPA BMP Web Toolkit can be
used with LSPC to model structural
BMPs such as detention basins, or
infiltration BMPs that represent
source control facilities, which
capture runoff from small
impervious areas (e.g., parking lots
or rooftops).
Region-specific input data not
available for Minnesota but user can
create this data for any region.
Computes storage volume for
stormwater reuse systems
Computes storage volume for
stormwater reuse systems. Uses 30year precipitation data specific to
Twin Cites region of Minnesota.

User defines parameter that can be
used to simulate generalized

User-defined practices with userspecified removal percentages.
Flow and phosphorus routing in
pond networks.
PondPack can calculate first-flush
volume, but does not model
pollutants. It can be used to
calculate pond infiltration.
User defines parameter that can be
used to simulate generalized
constituents.
Several flow-through structures
including standard sumps, and
proprietary systems such as CDS,
Stormceptors, and Vortechs systems
Categorizes BMPs into Point BMPs,
Linear BMPs, and Area BMPs
Model offers many agricultural
BMPs and practices, but limited
urban BMPs at this time.
Users input Event Mean
Concentration (EMC) pollutant
removal percentages for
manufactured devices.
Includes agriculture BMP
assessment tools. Compatible with
USEPA Basins
USEPA BMP Web Toolkit available to
assist with implementing structural
BMPs such as detention basins, or
infiltration BMPs that represent
source control facilities, which
capture runoff from small
impervious areas (e.g., parking lots
or rooftops).
