6) In total, I've calculated Non-regulated impervious surfaces (existing surfaces to remain) as
approximately 1,920sf and New (Post 1977) impervious surfaces at approximately 2,400sf. For which all
of the 2,400sf of impervious surfaces will need to be mitigated by a stormwater management system, i.e.
detention system or infiltration system. Please recalculate the impervious surface numbers and revise
the Impervious Surface Calculations on your site plan.
a) If an infiltration system is proposed, a Drainage Report is required. Please submit a Drainage Report
by a licensed Geotechnical Engineer. The report should address the soil conditions and infiltration
rates. Refer to City handout 13-7213 Low I!Llp%�11 c;yet11au nit„ i 1, i�111p„ also the
