P.3.1 MANAGE PRECIPITATION ON SITE

P.3.2 REDUCE WATER USE FOR LANDSCAPING IRRIGATION

Reduce negative impacts in aquatic ecosytems, channel morphology, dry water base flow by replicating natural hydrologic conditions and retaining precipitation on site

Retain de pred vol from 60 th percentile precipitation event as definined by the US EPA in the Technical Guidance on Implementation the Stormwater run off reqs for Federal projects under section 438 of the Energy Independence and Security Act or local equivalent

Retain precipitation Volume trought on site: Infiltration, Evapotranspiration , Reuse

-Implement Run-off reduction strategies ( bioinfiltration trough Plants , soil ) that also improve Water Quality. - Cisterns if sed must be implemented in combination with other approaches to meet the req of the prerequisite. - o+m P.8.1 To ensure long-term of stormwater features.

On site where ret vol of 60th is not posible due to site constraints Retain the MAXIMUM precipitation Vol posible in the site up to the 60th perc prec event.

• Minimize Impervious surfaces for Permeable - Hard surfaces to drain into localized on site landscapes areas - Infiltration opportunities in landscape : PLANTS AND HEALTHY SOILS AS FILTERS: BIOSWALES, RAINGARDENS, WATER QUALITY PONDS, CONSTRUCTED WETLANDS, VEGETATED BUFFERS: THAT filter and infiltrate , evotranspirate and retain precipitation, recharge groundwater and reduce pollutant loadins, run off volumes and rates.

Where RUN OFF CONVEYANCE SYSTEMSA ARE NEEDED use vegetated channels when possible . When vegetated channels are not practical then use of HARD NON EROSIVE MATERIALS to convey surface water shoul take precendece over using PIPES, CULVERTS OF UNDERGROUND CHANNELS.

-Create living spaces using soil and vegetation features: vegetated roofs, walls facades, raingardens or tree canopies.- Select appropiate vegetation features that can tolerate period of innundation and soil saturation - plants that are resistant or less susceptibles to pollutants

-Improve the water retention capacity of the soil by Increating the organic matter content of the soil trhough the addition of compost or other organic soil amendments. -Use Rainwater harvesting systems

-Pollutants in storwater : cooper and zinc roofs, roof gutters, downspouts and siding. -Galvanized materials ( fences, fance postis, graudrails, sign posts.- treated lumber

After the establishement period apllies only to long term water use for the final vegetated area BEYOND the stablishment period

REDUCE WATER USAGE BY AT LEAST 50 % FROM THE BASELINE CASE Beyond the establishment period

-If the water source does not come from a potable water source local health standards must be met - Install water meters to record and measure water usage to compare to the established baseline or Design the landscape to not require a permanent irrigation system. -Ensure O+M P.8.1 Describe the anticipating watering schedule as well as the process for maintening non-potable irrigation water sources.

C.3.3 MANAGE PRECIPITATION BEYOND BASELINE

Beyond req base line prec vol 60th percentile precip event to the entire area within the sites project boundary

Retrait or treat Prec Volume for the following percentile prec events: -80 th percentile prec event 4 points - 90 th 5 points - 95 th percentile prec events 6 points

Use EPA tech guidance , use daily rainfall DATA and the methodoly in the EPA document to determine the target percentile volume

BMP`S BEST MANAGEMENT PLAN MUST BE SCALED TO ACOUNT FOR THE ADDITIONAL VOLUME OF RUN OFF ENTERING THE BMP FROM AREAS OF SITE

C.3.4 REDUCE OUTDOOR WATER USE

Reduce or eliminate the use of potable water, natural surface water and groundwater withdrawals for outdoor use, including landscape irrigation and created water features.

OPTION1 ) REDUCE OUTDOOR WATER USE ( 4 POINTS) for landscaping irrigation Reduce water use by at least 75%from a baseline case beyond the established period. For created water features 50 % comes from non potable water source

OPTION 2)SIGNIFICANTLY REDUCE OUTDOOR WATER USE (5 POINTS ) For landscaping USE NO Potable water beyond the establishment period
For created Water Features 75% come from non potable water source.

OPTION 3) ELIMINATE OUTDOOR WATER USE ( 6 POINTS ) Eliminate long-term irrigation , use only during establishment period For created water Features 100 % annual must come from non potable water source

C.3.5 DESIGN FUNCTIONAL STORMWATER FEATURES AS AMENITIES

Connection local climate and hydrology , integrating aestetically pleasures stormwater features, visually and physically accesible and manage on site storm water

Use PRECIPITATION AS THE SOLE SOURCE OF WATER , stormwater management elements , bioswales, raingarden, vegetated roofs, proposed high use portions

Ensure Site PRECIPITATION is treated as an amenity in the way it is received conveyed and managed on site for at least:
50% of stormwater features 4 points 100% of stormwater features 5 points

C. 3.6 RESTORE AQUATIC ECOSYSTEMS

Healthy functioning of aquatic ecosystems: fish, wild life and people by restoring

MARINE/ESTUARINE - Todal wetland, mudflats, shorelines, reefs, seagrass beds.
RIVERINE- Streams, rivers ( assoc flood plainsand riparian buffer).
LACUSTRINE. Lakes, ponds ( assoc shorelines and riparian buffer).
PALUSTRINE. Non Tidal wetlands, seeps, springs, vernal ponds, season wetland.

RESTORE the geographic extent of the aquatic ecosystem within the sites project boundary of a minimum of:
30% of the geographic extend 4 points.
60 % of thea geographic extend 5 points.
90% of the geographic extend 6 points

RESTORATION PLAN BASED ON THE 9 ATTRIBUTES OF RESTORED ECOSYSTEMS: from the Ecological Restorations International Primer on Ecological Restoration.
