SITE DESIGN WATER - Coggle Diagram

- - - - 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.
        
        -Implement strategies to reduce Prec Run Off Volumes, pollutant discharges. -Implement strategies to increase evapotranspiration, filtration, and infiltration and mitigate elevated water temperatures caused by contact impervious surfaces
        
        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

        Implement systems in a treatment train to Provide Multiple Pollutant Removal Process (EVOTRANSPIRATION, INFILTRATION, SEDIMENTERY ,FILTRATION, ABSORPTION, )
- - - - EXEMPTIONS - WATER VOLUME USED MAY BE INCLUDED OR EXCLUDED FROM IRRIGATION CALCULATIONS AT THE PROJECT TEAMS DISCRETION: -WATER USED DURING ESTABLISHMENT PERIOD - WATER USED TO IRRIGATE NON COMMERCIAL FOOD PRODUCTION GARDENS - IRRIGATION USED ON EDIBLE PLANTS SHOULD NOT HARM HUMAN HEALTH c.6.7 - WATER USED AS REQUIRED BY LOCAL REGULATIONS IN FIRE AREAS FOR FIRE SUPPRESION SYSTEMS - WATER USED FOR ATHLETIC FIELDS IF VEGETATED
      - reduce potable water use with any combinations: - Design irrigation systems . TREES , SHRUBS, AND GROUNDCOVER IRRIGATE SEPARATELY HYDROZONES - REUSE GRAYWATER :CAPTURED RAINWATER, HVAC BLOWDOWN OR CONDENSE WATER FOR IRRIGATION TO DECREASE POTABLE WATER -Water treatment process ..
- - - - 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
        
        the treatment practices implemented must achieve at the minumum an average discharge concentration of less than or equal to 25 miligrams per liter total suspended soils for the volume treated. o+m P.8.1
- - - - EXEMPTIONS
  - - - -ONLY AFTER THE ESTABLISHMENT PERIOD:
- - - - 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
        
        % are based on total square footage ft2 ( m2) of the storwater features, including conveyance features. -O+M P.8.1 Activities chemicals likely to harm aquatic life- Chlorine and Bromine ( ver local code health ) mosquitoes not be created. - Swimming natural ponds : ozonation at thermal t.
- - - - p.2.2 locations
      - 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
