Ms. Rachel Juba March 19, 2021 Page 2 The City may vacate the right of way in this location, while maintaining public drainage and utility easements for the sewer and watermain lines in this location. Water service to the site will be achieved by connecting to an existing 12" stub located in the short stub street extended from 157t" Way N to this property at the northwest corner of the site and looping to an existing 8" stub on Foxhill Avenue, south of 157t" Street. The applicant is proposing an 8" loop around the building with hydrants for fire protection. The portion of the water system that is looped will be required to be located in a public drainage and utility easement. The service into the building will remain private as shown. Sanitary sewer service is proposed to extend to the site from an existing sanitary sewer manhole at the northwest corner of the site. Detailed redline comments have been provided on the plans and sent to the applicants engineer so they can be addressed in future submittals. Stormwater Management 10. The stormwater water quality and rate control requirements are proposed to be met through the use of onsite infiltration basins. The basins are sized to meet the City's water quality and rate control requirements. Water reuse is not utilized as part of the design. 11. Intersection improvements at TH 61 and 152"d Street are proposed which will require stormwater management. The applicant may choose to handle stormwater management for the intersection improvements within their site and will be required to submit to the City for review and approval. Staff has reviewed the site and there is ample room to accommodate these stormwater management needs onsite. The applicant is currently working to develop an approved layout for the intersection and will proceed with final design. 12. Additional stormwater plan and model comments have been provided to applicant and will need to be addressed in future submittals for documentation and permitting purposes. 13. A stormwater maintenance agreement and drainage and utility easements will be required for the stormwater basins on the site. This will also be required if the applicant chooses to handle the stormwater management for the intersection improvements within their property. Drainage and utility easements over the wetland areas will also be required. Thank you for the opportunity to provide comments on this project. Additional comments may be necessary following the review of the responses to these. If you have any questions, please do not hesitate to contact me at 651-286-8463.
