Dear Sirs,
The Avemore Connector Road Plans and Erosion & Sediment Control Plans (WP0200600061) were
previously approved by the County. However, we have erred and should not have yet approved the plans. I
apologize for this. A stormwater management ammendment has not been reviewed or approved for this
project, and must be approved before the E &S plans can be approved or a grading permit can be obtained.
An adequate stormwater management amendment serving the connector road and Fontana is necessary, as
a detention basin serving Fontana is proposed to be removed. It appears that detention could be met by
routing stormwater to the Luxor Pond #2 across Olympia Drive. Stormwater Management will also need to
be provided for the proposed connector road. Once again, I apologize for overlooking the necessary
Stormwater Plans. We will do our best to work quickly with you to correct this issue.
Sincerely,
Jonathan Sharp

Plan Review of Filterra
Avemore Connector Road, Albemarle County
Dear Sirs
filleffa
Thank you for submitting the partial plans (04- 09 -07) for our review of the Avemore
Connector Road project.
Filterra® structures 6A, (8'x4') and 7A,(8'x4') were studied for;
• Planned Filterra® box size
• Filterra® contributing drainage area meeting project's regional sizing specification
• Spot elevations (TC) for Filterra® and bypass relief
• Filterra® invert elevations are 3.5' below TC
• The bypass is lower than the Filterra® elevation (spot elevations)
• The grading pattern encourages cross linear flow and not head -on flow
• The Filterra® outlet drain pipe is sized correctly and exits perpendicular to the wall
• For any conflicting structures such as storm drain pipes below Filterra®
• For most efficient placement of Filterra® units
• 4 -6" opening throat detail and standard notes on plans
The plan review concluded that the Filterra structures listed above were sited and sized
appropriately to treat stormwater to our published specifications.
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 Buyer at time of order.
The Filterra Installation, Operation and Maintenance Manual will be forwarded to the
Owner when the units are activated by Americast.
Yours sincerely
Edward Kay, Filterra Operations Manager
