Site Engineering Review Comments:
1. The request for waiving of the 2-foot setback requirement in compliance with TSM 2-01.9.0 has been denied. As the structure to the South resides near/along the current property line, the proposed work including the drainage swale will not be allowed to potentially impact the southern existing structures foundation. It would be necessary that a different avenue be pursued regarding roof drainage. One recommendation would be to potentially utilize a gutter system paired with drain piping to ensure that roof drainage can reach the Western portion of the site.
