Ms. Katie Larsen 7/72021 Page 3 Huntson Addition Concept Plan Engineering Review additional traffic from the new lots. Townhome residents will use Ravens Court, a local road, to access Ware Road, a minor collector. Ravens Court and Ware Road also have capacity to handle the additional traffic from the proposed development. The applicant is proposing to access Blocks 1 and 2 from Oak Hollow Lane and extending Oak Hollow Lane through the site. The proposed roadway is 32-ft wide from back-of-curb to back-of-curb and is approximately 165-ft in length. The applicant currently shows a proposed temporary cul-de-sac with a 46-ft radius. The proposed cul-de-sac and temporary easements greatly impact the adjacent properties and the area available for stormwater ponding. After review, staff believes that a 40-ft radius temporary cul-de-sac would be sufficient for the site or that a 25-ft by 32-ft turnaround could be added to the eastern side of the roadway. The 40-ft radius temporary cul-de-sac can be offset so that the majority of the cul-de-sac would be within Outlot A. City Ordinance states that cul-de-sac radii need to be 46-ft, but also states that minor variations of that requirement can be allowed with the consensus of the Public Works Director, City Engineer, and City Administrator. Multiple temporary cul-de-sacs have been installed in Lino Lakes with radii of 40-ft. • Wetlands and Mitigation Plan There are multiple existing wetlands on the Huntson Addition property. The plans note that the wetland delineation was performed by Jacobson Environmental, Pllc, in August of 2017. If not already approved, the wetland delineation shall be approved by the Technical Evaluation Panel (TEP). • Landscaping Staff does not have any comments on this time. • Floodplain There are no existing floodplains on Huntson Addition. • Drainage and Utility Easements The applicant is proposing 10-ft wide drainage and utility easements along adjoining right-of- way, rear lot lines, and the plat boundary lines. The applicant is proposing a 5-ft wide drainage and utility easement for the side lot line adjacent to Outline A. Per City Code, the City requires 10-ft wide drainage and utility easements along lot lines and allows these easements to be centered on common rear and side lot lines. The proposed concept plan meets these requirements. • Development Agreement A Development Agreement will be required with the final plat. • Grading Agreement A Grading Agreement is not applicable at this time.
