Given the location and proximity of the proposed garage, is it intent of the applicant to include roof drains and infiltrators? Addressed Roof runoff is being channeled to the infiltrator using gutters, downspouts, and PVC pipes. Driveway runoff is being infiltrated using pervious pavement. If the pervious pavement stops infiltrating in a large, the design includes a deep sump catch basin which is connected to the infiltrator system. The applicant will need to submit a maintenance schedule of the pervious surface. ➢ Please explain the visual impact of the proposed additions,pool, and garage on abutters.

Addressed Recommendations: The revised plans and supplemental information submitted incorporates the majority of comments and recommendations made by Planning Staff and the Planning Board. The applicant will need to address the comments from VHB and incorporate the 3 plan changes.

The Applicant should provide sizing calculations for the proposed infiltration system,it is unclear how the size of the system(as shown on the plan)was determined. Addressed. 8. Have test pits been taken at the location of the proposed infiltration system? The Applicant should verify that there is a 2-foot separation between annual high groundwater and the bottom of the infiltration system. Partially addressed. The test pit location is shown on the plans, however it does not appear that the resulting information has been added to the plans. 9. The Deep Sump Catch Basin detail specifies a frame and cover,a frame and grate should be specified. Addressed. 10. The Applicant should specify the material thicknesses of the driveway pavement and gravel on the Bituminous Curb—Type"A"(BC)detail. Addressed. 11.
