Condition of Approval #10: "The applicant shall construct an 18 foot wide roadway to Olson Street within 24 months." After the approval, a site plan was submitted indicating the location of the proposed road and an overall impervious surface coverage calculation of 49.9% for the subject property. The "Overall Site Plan" was approved with the understanding the future roadway was included in the impervious surface coverage calculation while in fact it may not have been. Once the property was fully "built out," it was discovered the subject property was over the impervious surface coverage allowed by 2%or 6,925 sq.ft. The applicant has indicated that a licensed engineer will submit a letter indicating the stormwater management facilities onsite can retain the stormwater runoff produced by the existing impervious surfaces. At the time this report was written, the letter has not been received. Applicable Regulations:The following regulations apply to this property: Section 17-5.10 COMMERCIAL (C) 3.
