SW-C2.1-1: Protect/fence perforated pipe connection area (if remaining)
4 (7)
SW-C3.1-6: Add hard surfaces table list the total SF of each type of surface,
4
including existing surfaces to considered for retrofit mitigation, and the BMP treating
each surface
SW-C3.1-7: See comment in drainage report regarding feasibility of perforated pipe
4
connection.
SW-C3.1-1: Update or add details to include information need for construction of
4
the under drain system including sub grade sloping (if any) and geotechnical fabric
as needed to remain consistent with geotechnical recommendations (generally
recommend tight lining all drainage)
SW-C3.1-2: Detail/provide more information of utility crossing elevations-
SW-C3.1-3: Detail side penetration/boot, or relocated to manhole.
SW-C3.1-4: Add reference to the detail on sheet C3.2
SW-C3.1-5: Add note to provide (or restore as needed) splash pad/quarry rock; list

calculated)
Drainage Report
14 SW1-1: It appears the perforated pipe connection is within 50' of a landslide hazard
area and is therefore infeasible; expand or address as needed. If remaining, also
address how this aligns with the geotechnical recommendations (generally
summarized and as drainage should be tight -lined)
