H:\Heidi\Planning\Planning Cases\1415 - Lennar - Final Plat 1st addition Variance Rezoning - Paul Tabone\City Engineer Comments Review Memo 10.6.docx October 6, 2022 Corrin Wendell Community Development Director, Planner City of Little Canada RE: Pioneer Commons, First Addition – Final Plan Review Comments (Civil) Corrin, I have reviewed the Pioneer Commons “First Addition Streets and Utilities Buildout” plans dated 09/23/2022. These plans were prepared by WSB and submitted by Lennar Homes. The plans were reviewed for conformance with the City’s comprehensive plan, City code, and industry standards for street, utility, and stormwater management construction. Below is a comprehensive list of administrative items that will need to be addressed through the development agreement as well as technical comments that should be addressed in a revised final plan submittal prior to acceptance. Administrative • A letter of credit will be required in the amount of 125% of the estimated construction costs. The estimated construction cost of $2,100,000 provided by the developer’s engineer is sufficient for a construction cost estimate. • A cash escrow in the amount of $122,800 will be required for the First Addition of this project. The escrow will be used for consulting reviews (engineering and legal) during the final plan and development agreement phase of the project. The escrow will also be used for consulting oversight and inspection of public infrastructure (Vanderbie Street, trails, all watermain, all sanitary sewer, all public storm sewer, stormwater management BMP’s). The cash escrow will also be used for warranty inspections and associated coordination with the developer. A detailed escrow worksheet will be provided in the development agreement. The City reserves the right to charge additional consultant fees as needed. • An as-built grading and utility plan will be required and shall be signed by a MN registered land surveyor or professional engineer certifying that the grades are as shown on the final submitted grading plan. A copy of the as-built requirements worksheet can be provide upon request. • The developer will need to prepare an exhibit(s) that outlines which streets, utilities, and stormwater management features are deemed private versus public. They should include any other infrastructure items I am not thinking of. This figure will be included in the development agreement. • Consent documents must be provided from Xcel Energy and BP Oil for encroachment into their existing private utility easements
