PURPOSE. 0 U No. 35791 ,
THE PURPOSE OF THIS PROJECT IS THE CONSTRUCTION OF A NEW RESIDENTIAL DEVELOPMENT LOCATED IN
e6
ALBEMARLE COUNTY, VIRGINIA, JUST WEST OF THE CITY OF CHARLOTTESVILLE, ON IVY ROAD/ ROUTE 250. THE
PROJECT CONSISTS OF 7HE CONSTRUC77ON OF 65 RESIDENTIAL UNITS AND RELATED INFRASTRUCTURE. TWO I �c'SSIO
EXIS77NG BUILDINGS SHALL REMAIN AND UTILIZED AS A RESIDENTIAL UNIT AND OFFICE SPACE. A THIRD EXISTING NAL
BUILDING WILL BE RAZED DURING CONSTRUCTION. A TOTAL OF 14.17 ACRES WILL BE DISTURBED DURING
CONSTRUCTION.
EXISTING SITE CONDITIONS:
PRESENTL Y THE SOUTH SIDE OF THE SI TE IS COVERED IN MA TURF TREES MANY OF THESE TREES WILL BE
SAVED (SEE LANDSCAPE PLAN AND TREE PRESERVA77ON PLAN FOR EXACT LOCATIONS AND TREES). THE
NORTHERN SIDE OF THE SITE IS COVERED BY A FEW MATURE TREES, BUT IS PREDOMINANTLY TALL UNMOWED
GRASS THE S17E IS SPLIT INTO TWO DRAINAGE AREAS THE RIDGE ON WHICH THE EXIS77NG MANOR HOUSE
SITS IS THE DRAINAGE DIVIDE BETWEEN THE TWO AREAS ONE FALLING TO THE SOUTH TOWARDS ROUTE 250
AND THE SECOND FALLING TO THE NORTH TOWARDS THE EXISTING RAILROAD TRACKS THERE ARE TWO EXISTING Q o E >
CULVERTS UNDER 7HE RAIL ROAD TRACKS, WHICH DRAIN OUR SITE. THESE CULVERTS OUTFALL TO AN UNNAMED z N
TRIBUTARY OF IVY CREEK. THE SOUTHERN AREA OF THE PROPERTY BELOW THE EXISTING MANOR HOUSE WILL N (A O
HAVE LIMITED CONSTRUCTION AC77W77ES. DISTURBANCE WILL BE ONLY FOR 7HE CONSTRUC77ON OF THE � Q o
ROADWAYS TO ACCESS THE NORTHERN SIDE OF 7HE PROPERTY. DISTURBANCE SHOULD BE MINIMIZED AS MUCH > E _
AS POSSIBLE TO PREVENT THE LOSS OF THE EXIS77NG TREES THAT ARE TO BE SAVED. H w � E _

THE CONSTRUCTION OF THIS PROJECT WILL HAVE AN EFFECT ON PEAK RUN -OFF RA TES DUE TO AN INCREASE 0 12.15.05
IN QUAN77TY AND VELOCITY OF RUN -OFF. THE IMPERVIOUS AREA IS BEING INCREASED DUE TO THE
CONSTRUCTION OF THE ROADS AND HOUSES HOWEVER, MUCH OF THE RUN -OFF IS BEING DIVERTED TO 7HE I DRAWN BY
DETENTION SYSTEM AND B/0-FILTER FEATURES ON THE SITE, WHICH WILL ASSIST IN DECREASING THE
RUN -OFF VELOCI TY FROM THE PROJECT SI TEF, IN ADDI RON, THE FRONT PORTION OF THE SI TE WILL UTILIZE
FIL TERRA BOXES TO ACHIEVE WATER QUALITY. THESE TWO MEASURES WILL HELP PR07ECT THE UNAMED

THE PURPOSE OF THIS PROJECT IS THE CONSTRUCTION OF A NEW RESIDENTIAL DEVELOPMENT LOCATED IN
e6
ALBEMARLE COUNTY, VIRGINIA, JUST WEST OF THE CITY OF CHARLOTTESVILLE, ON IVY ROAD/ ROUTE 250. THE
PROJECT CONSISTS OF 7HE CONSTRUC77ON OF 65 RESIDENTIAL UNITS AND RELATED INFRASTRUCTURE. TWO I �c'SSIO
EXIS77NG BUILDINGS SHALL REMAIN AND UTILIZED AS A RESIDENTIAL UNIT AND OFFICE SPACE. A THIRD EXISTING NAL
BUILDING WILL BE RAZED DURING CONSTRUCTION. A TOTAL OF 14.17 ACRES WILL BE DISTURBED DURING
CONSTRUCTION.
EXISTING SITE CONDITIONS:
PRESENTL Y THE SOUTH SIDE OF THE SI TE IS COVERED IN MA TURF TREES MANY OF THESE TREES WILL BE
SAVED (SEE LANDSCAPE PLAN AND TREE PRESERVA77ON PLAN FOR EXACT LOCATIONS AND TREES). THE
NORTHERN SIDE OF THE SITE IS COVERED BY A FEW MATURE TREES, BUT IS PREDOMINANTLY TALL UNMOWED

SITS IS THE DRAINAGE DIVIDE BETWEEN THE TWO AREAS ONE FALLING TO THE SOUTH TOWARDS ROUTE 250
AND THE SECOND FALLING TO THE NORTH TOWARDS THE EXISTING RAILROAD TRACKS THERE ARE TWO EXISTING Q o E >
CULVERTS UNDER 7HE RAIL ROAD TRACKS, WHICH DRAIN OUR SITE. THESE CULVERTS OUTFALL TO AN UNNAMED z N
TRIBUTARY OF IVY CREEK. THE SOUTHERN AREA OF THE PROPERTY BELOW THE EXISTING MANOR HOUSE WILL N (A O
HAVE LIMITED CONSTRUCTION AC77W77ES. DISTURBANCE WILL BE ONLY FOR 7HE CONSTRUC77ON OF THE � Q o
ROADWAYS TO ACCESS THE NORTHERN SIDE OF 7HE PROPERTY. DISTURBANCE SHOULD BE MINIMIZED AS MUCH > E _

THE CONSTRUCTION OF THIS PROJECT WILL HAVE AN EFFECT ON PEAK RUN -OFF RA TES DUE TO AN INCREASE 0 12.15.05
IN QUAN77TY AND VELOCITY OF RUN -OFF. THE IMPERVIOUS AREA IS BEING INCREASED DUE TO THE
CONSTRUCTION OF THE ROADS AND HOUSES HOWEVER, MUCH OF THE RUN -OFF IS BEING DIVERTED TO 7HE I DRAWN BY
DETENTION SYSTEM AND B/0-FILTER FEATURES ON THE SITE, WHICH WILL ASSIST IN DECREASING THE
RUN -OFF VELOCI TY FROM THE PROJECT SI TEF, IN ADDI RON, THE FRONT PORTION OF THE SI TE WILL UTILIZE
FIL TERRA BOXES TO ACHIEVE WATER QUALITY. THESE TWO MEASURES WILL HELP PR07ECT THE UNAMED

Plan Reidew of FlIterra ®
:dtzeilterra® Proiect
Dear Sirs
Thank you for s',Ibmitting the partial plans on 16 June 2006 for our review of the
Kenridge project.
Filtwvr structures FB-1 (6x4), FB 2 (6x4), FB -3 (6x4X and FB-4 (6x4) were studied for;
• Planned FiltertaG box size
• FiltemO contributing drainage area rr_eetyng project's regional sizing specification
• Spot ekvations (TC) for Filterra® and bypass relief
• FiltemS invert elevations are 3.5' below TC
• FiltcrraQ invert elevations are higher than effluent invert elevations
• The bypass is lower than the FiltetraS elevation (spot elevations)
111e grading pattern encourages cross linear flow and not head -on flow
The Fi;terra® outlet drain pipe is sized correctly and exits perpendicular to the wall
4 For any conflicting structures such as storm drain pipes below Filterral&
• For roost efficient placement of Filtem(& units
4 -6" opening throat detail and standard notes on plans
The plan review concluded that the FilterraO structures listed above were sited and sized
appropriately to treat stormwater to our published speci_rcaiions.
Operational consistency with these specifications is contingent upon the stormwater units
being installed correctly and according to the plans, as well as regular maintenance being
performed, Installation Help documents will be forwarded to the Beyer at time of order,
The Filters® Installation, Operation anti Maintenance Manual will be forwarded to the
Owner when the unfits are activated by Americast.
Yours sincerely
