Mindy's Place Final Plat
Response to Determination of Non-Significance – Mitigated (DNS-M)
B. Mitigation Measures
1. The applicant shall be best required to record on the face of the Preliminary Plat
the maximum amount of square footage of impervious surface allowed for each new lot if
less than allowed by code if the applicant intends to utilize the Reduced Impervious
Surface Credit.
1. The proposed impervious surface area per lot and the maximum impervious surface
area for all lots is on Sheet 3 of the Final Plat.
2. The applicant shall submit a secondary review during final engineering design that
includes hydro-geotechnical evaluations for buoyancy and lining, structural review and
wall drainage relief against potential hydrostatic pressures. The secondary review shall be
conducted by an independent reviewer selected by the City at the applicant's expense and
shall be approved by the City's Plan Reviewer prior to engineering plan approval.
Additionally, the applicant would be required to provide due diligence in the grading and
collection of drainage design during the construction phase so that runoff and erosion
does not impact the neighboring properties.
2. A hydro-geotechnical evaluation was conducted for the structural wall design. The
T.E.S.C. plan and SWPPP were adhered to, which resulted in minimal disturbance
to adjacent properties.
