THE OVERALL PURPOSE OF THE PROJECT IS TO GENERATE NUTRIENT OFFSET CREDITS FOR STORMWATER QUALITY AND POINT SOURCE NEEDS FOR THE CITY OF CHARLOTTESVILLE AND ALBEMARLE COUNTY. IN ADDITION TO WATER QUALITY IMPROVEMENTS AND POLLUTANT REDUCTIONS (SEDIMENT, NITROGEN, PHOSPHORUS) FROM RIPARIAN BUFFER AND STREAM RESTORATION, THE PRIMARY GOAL IS TO RE-ESTABLISH A FUNCTIONAL STREAM CORRIDOR THAT WILL MAINTAIN DIMENSION, PATTERN, PROFILE. PROPOSED RESTORATION APPROACH WILL INVOLVE CHANNEL FILLING, GRADING, EXCAVATION, AND SELECT STRUCTURE PLACEMENT TO RE-ESTABLISH STABLE DIMENSION, PATTERN, AND PROFILE. STRUCTURES AND BIOENGINEERING MEASURES TO BE UTILIZED INCLUDEBUT ARE NOT LIMITED TO: CONSTRUCTED RIFFLES, ROCK STEPS, BRUSH TOE, SOIL LIFTS, BRANCH LAYERING, AND LIVE STAKES. STREAM BANKS AND RIPARIAN BUFFERS WILL BE PLANTED WITH NATIVE TREES, SHRUBS, AND GRASSES. GENERAL NOTES 1. THIS IS A WATER QUALITY PROJECT. CHANNEL AND FLOOD PROTECTION REGULATIONS HAVE BEEN MET THROUGH NO CONCENTRATED STORMWATER FLOW BEING RELEASED FROM THE PROJECT AREA. THERE IS NO INCREASE IN IMPERVIOUS AREA. NUTRIENT DISCHARGE FOR THIS PROJECT IS UNDER 0.41 LBS PER ACRE PER YEAR. 2. ALL BASEMAPPING AND TOPOGRAPHIC SURVEY INFORMATION IS PROVIDED BY ECOSYSTEM SERVICES, LLC. THE SURVEY WAS COMPLETED IN OCTOBER AND NOVEMBER 2017. 3. ADDITIONAL FIELD SURVEYS WERE CONDUCTED BY ECOSYSTEM SERVICES, LLC. 4. ADDITIONAL BASE MAPPING OBTAINED FROM CHARLOTTESVILLE CITY/ALBEMARLE COUNTY GIS AND VGIN. 5. HORIZONTAL DATUM: NAD83 VIRGINIA STATE PLANE, SOUTH ZONE, US FOOT 6. VERTICAL DATUM: NAVD 88, US FOOT 7.

INSTEAD, THE DEVELOPMENT, AS A WHOLE, SHALL BE CONSIDERED TO BE A SINGLE DEVELOPMENT PROJECT. HYDROLOGIC PARAMETERS THAT REFLECT THE ULTIMATE DEVELOPMENT CONDITION SHALL BE USED IN ALL ENGINEERING CALCULATIONS. K. ALL MEASURES USED TO PROTECT PROPERTIES AND WATERWAYS SHALL BE EMPLOYED IN A MANNER WHICH MINIMIZES IMPACTS ON THE PHYSICAL, CHEMICAL AND BIOLOGICAL INTEGRITY OF RIVERS, STREAMS AND OTHER WATERS OF THE STATE.
