PAGE 2 of 2 easements should also be provided along the side and rear property lines. All easement areas must be free from all encroachments other than those approved by the City Engineer and upon execution of an easement encroachment agreement. Prohibited encroachments include, but are not limited to trees, landscaping, fences, retaining walls, and building structures. 7. Existing conditions plan remains significantly incomplete. Existing conditions is required for a minimum distance of 150‐feet from the proposed parcel and from any off‐site improvements. A detailed construction plan review cannot be completed until the existing condition information is provided on the site, grading and utility plans to demonstrate how the site layout connects to the surrounding existing conditions. Existing conditions must include all topographic features, contours, and spot elevations for all design critical locations. Spot elevations are required at a minimum along all lot lines, including lot corners, and along the existing curb of Upper 33rd Street. 8. Site grading must be revised to meet all city minimum and maximum allowable grades. The right‐of‐way boulevard must be a minimum 4% grade and all other site grades must be a minimum of 2% grade. Rear yard grades must be labeled 3:1 maximum. 9. Site grading must be revised to show the 100‐year HWL storm event elevation (and 100‐year HWL contour) for all low points on the site. The grading plans must also show all discharge locations from the property, including emergency overland overflow locations and EOF elevations. The grading plans must be revised, as may be required, to meet city design standards for flood protection, requiring 2‐feet of vertical separation to all adjacent building low floor elevations from any low area 100‐year HWL, and requiring 1‐ foot of vertical separation from any emergency overflow elevation to all adjacent building low opening elevations. 10. The proposed site plan is subject to a storm water management plan (SWMP) meeting State, Valley Branch Watershed District (VBWD) and city rules. The proposed stormwater management plan proposes an underground storm water storage chamber(s) to provide rate control to reduce storm water discharges from the site. The plan proposes to discharge runoff to the south through a connection to the existing city storm sewer system along Upper 33rd Street. 11. In order to comply with VBWD and city rules, the applicant is requesting to divert stormwater runoff that currenting discharges north from the property, and to proposed southerly discharge location. This stormwater diversion has been found to be acceptable to the city. 12. The soils investigations performed on the site determined that infiltration is not feasible. Therefore, the developer intends to purchase credits from Lake Elmo’s Downtown Regional Infiltration Basin Volume Control credit bank to meet volume control requirements. The 2023 Fee for the Regional Infiltration Basin Volume Control Use Charge is $0.70 per square feet of impervious surface. The VBWD permit is contingent upon the applicant providing proof that the credits have been obtained from Lake Elmo. 13. The storm water management facilities constructed for this development will be privately owned and maintained. The applicant will be required to execute and record a Stormwater Maintenance and Easement Agreement in the City’s standard form of agreement. The stormwater drainage and utility easements must be shown on the site plans, utility plans and grading plans. A Homeowner’s association would be required for the development to provide for the ongoing ownership and maintenance responsibilities. 14. Municipal water supply is available to the site. There are four (4) existing water service stubs available along the frontage of the property to provide an individual water service connection for each townhome. Connections to existing public watermain will be required, including all connection and permit fees. 15. Sanitary sewer service is available to the site. There are four (4) existing sanitary sewer service stubs available along the frontage of the property to provide an individual sewer service connection for each townhome. Connections to existing sewer will be required, including all connection and permit fees.
