The applicant will need to apply for an MPCA NPDES permit due to the size of area <br />disturbed. The City will need to receive a copy of this permit in advance of any work <br />taking place. <br /> <br />Stormwater Management <br /> <br />2. The applicant is proposing to utilize a stormwater management pond and infiltration basin <br />to conform with stormwater management requirements. Treated stormwater is <br />discharged to the conveyance way to the north. Staff has provided a number of <br />additional comments that the applicant will need to finalize in order to receive the surface <br />water management permit. <br />3. The proposed easement to access the stormwater system within the TGK site will be <br />provided to the City. <br />4. Stormwater reuse is not feasible and not proposed for this site. <br />5. City staff is working with the applicant on maintenance agreement requirements for <br />stormwater features that will be their responsibility. Stormwater features are required to <br />have drainage and utility easements. <br />6. The applicant will need to apply for a MnDOT drainage permit to ensure that current <br />drainage rates to MnDOT right-of-way will not be increased. The City will need to receive <br />a copy of this permit in advance of any work taking place. <br />
