2011 OUTSTANDING STORMWATER

PROJECT AWARD

INDIANA ASSOCIATION FOR FLOODPLAIN AND STORMWATER MANAGEMENT

Established in 1998, this award recognizes an

utstanding stormwater project studied,

designed, or constructed by a firm for a local

unit of government or a private entity.

STREAM NATURALIZATION

Constructed in existing Right of Way Provides habitat, groundwater recharge, and passive recreation Existing channel carries storm events, no structural changes Increased vegetation on banks provides a buffer Improves water quality as a flow through best management practice

THE NATURAL BALANCE

Develop native vegetation

Water tolerant plants in the water and at waters edge Native grasses and forbs on the higher elevations going up the bank

Create mini ecosystem Flora and fauna to reduce the number of mosquitoes

Index of Biotic Integrity showed that the stream became healthier as it

flowed through the riparian restoration area.

WATER QUALITY (PHASE 1)

2013 Water Quality Testing Orthophosphorus - most common form of phosphorus in water mg/l) Nitrate – nitrogen from fertilizer (farm/yard), leaking septic tanks and animal wastes (mg/l) Turbidity – measurement of suspended material in water (NTU) Chlorophyll A - measurement of the concentration of suspended Phytoplankton (ug/l) Algal Count – measurement of algae cells per milliliter (per ml) Samples collected on six dates at Maplebrook and Grant Streets (upstream) then at Sycamore Street (downstream).

WATER QUALITY AVERAGES

Maplebrook Grant

Orthophosphorus (mg/l)

0.36 0.24 0.21

Nitrate (mg/l)

1.27 0.58 0.62

Turbidity (NTU)

Both phosphorus and nitrate values were reduced by roughly 50% as the water flowed through the riparian restoration area. Similar results were observed for turbidity and chlorophyll concentrations, which were also reduced as the water flowed through the project area.

MOSQUITO PREDITORS

Dragonfly:

Normally, the dragonfly’s prey is caught in the air and eaten in flight. It consumes large numbers of mosquitoes.

Birds:

Several specific species of birds eat mosquitoes. Birds adapt their diet when there is a higher concentration of mosquitoes. Water fowl consume mosquito larvae in their normal diets.

Bats:

Most bat species feed after dark or at dusk. Some experts estimated that one bat can eat between 600 to 1000 insects, mosquitoes included, within a period of one hour.

CONTINUED DRAINAGE BENEFITS

No structural changes Plants in channel will serve as a flow through Best Management Practice BMP) Plantings on banks will serve as buffer for stormwater from mowed areas
