The letter of revision proposes the following changes as shown on the attached exhibit: 1. Installation of two 8'x16' precast concrete vaults instead of the proposed expansion of the sight well. 2. The vaults will be partially underground, extending approximately 3.5' aboveground. The aboveground portion will be screened as shown on the attached exhibit and to the satisfaction of the ARB. All proposed piping will be underground and the overflow valves will face the rear of the parcel. 3. Relocation of the existing light pole as shown on the attached exhibit. There are no other changes to the approved plan proposed. This is the first (1st) Letter of Revision for this site. Three (3) Letters of Revision are allowed, after which all required changes must submitted in the form of a site plan amendment.

See the attached drawing M4940 by Hazen and Sawyer for a plan and profile view of the proposed sight well expansion. Since approval of the site plan amendment in December of 2014, a need for expanded on-site storage downstream of the filter building was identified. The attached drawing by WRA shows the proposed revisions to the approved site plan. Instead of the proposed expansion of the sight well shown on the M4940, RWSA is proposing to install two new precast concrete vaults adjacent to the existing well. The proposed vaults each measure approximately 8'x 16'. The vaults would be partially underground, and extend approximately 3.5' aboveground. For reference, the existing sight well extends about 3' aboveground. There is no change in the proposed material for the vaults from the previously approved sight well expansion. The vaults will be constructed of precast concrete to match the existing well. The WRA plan also shows three (3) grey owl junipers in front of the vaults to obscure the view of the vaults from Three Notched Road. These typically grow to be about 3' tall and 6' wide. All proposed piping will be underground and overflow valves will face the rear of the lot. A photo of the existing sight well taken from Three Notched Road is attached far reference. Please do not hesitate to contact me if you have any questions about the proposed revisions to the approved site plan. I am also happy to sit down to review the details of the project if needed.
