Existing driveway and walkway to be replaced in a like-for-like manner to repair existing snowmelt.As outlined in the Minor Engineering Design checklist, a project is exempt from disturbance area if the project repairs snowmelt in the same footprint as existing. This project repairs snowmelt in the same footprint as existing. I II i V lilt- NG FLAGSTONE PATH \\ I ( -- F2 REVIEWED \ >-- Eng.

Describe the existing site, include common location,topography, land use,ground cover, and existing drainage pattern. Existing driveway and walkway are in the same location. Topography slopes very gently to planter beds on either side of the driveway and walkway.All existing drainage patterns to remain. / \\ iu V\\,t 1 I \ I F2 I I I I I I ----,1— I r r 80 Overlook—Drainage Narrative 8/28/24 3. Describe the proposed project, include changes to land use,topography,ground cover, soil type, and drainage pattern. Existing entran tubing for snowmelt has failed and will be replaced. Driveway and walkway to be replaced like-for-like in the same location and same slopes. 4. Describe any existing drainage issues. There are no existing drainage issues or concerns. 5. Describe existing drainage basins and proposed drainage alterations. Include increases in flow, changes in direction, new outfalls, etc. The existing driveway drains to adjacent green spaces. There are no changes to the drainage patterns, direction, outlets, etc. 6. Describe what efforts have been made to reduce runoff and increase infiltration (e.g. reduce impervious area, disconnect impervious area, route runoff via landscape rather than hard infrastructure). All runoff will continue to run to landscape. 7. Describe downstream stormwater conveyance system.Where does runoff go when it leaves the site?Verify no impacts to neighboring properties. Runoff percolates into the soil and is not conveyed to neighboring properties. 8. Describe any proposed stormwater infrastructure or BMPs. No infrastructure changes proposed. 9. All new or altered hardscape must drain to greenspace or a constructed BMP. All altered hardscape drains to green space. COto40 co BRYAA J AY IF 403957 to' 4� /,o
