May 6, 2024 <br />City of Lake Elmo <br />Page 4 of 8 <br />Reference: Bridgewater Village Planning Commission, Engineering, Fire, Landscape Architecture, and <br />Washington County comments received from The City of Lake Elmo <br /> <br /> <br />shown on the plan. Shifting the driveways will impact the overall lot layout and design, <br />requiring the project to redesign the lot configuration to meet planning requirements and <br />require Preliminary Plat amendment from the City. <br /> <br />5. Internal turn lane taper and queuing lengths <br /> <br />a. Bridgewater Village site construction plan review dated 04/10/2024, item 21, states that <br />turn lanes remain too short and during the follow up meeting it was requested that they be <br />lengthened. <br /> <br />b. City engineering design standards do not specify requirements for turn lane queuing and <br />taper lengths. Length of turn lanes significantly impacts ROW, developable area, and <br />driveway locations. Site constraints such as access locations and number of access points <br />limit the constructable queuing and turn lengths for proposed turn lanes. <br /> <br />c. The project team initially proposed residential cross section street design for the proposed <br />development. The initial goal of the project was a walkable, pedestrian-orientated <br />development with narrower roadways that reduced the speed of traffic for a safety. <br /> <br />d. To assist with roadway classification / design requirements Traffic / Trip Generation was <br />sent to City Engineering Staff for review on 08/02/2023 to assist in roadway classification <br />and turn length needs / design requirements and is included as an attachment to this memo <br />as a reference. City Engineering staff replied on 08/02/2023 requiring a commercial cross <br />section, wider lanes, and turn lanes due to the commercial and medium-density residential <br />uses. In this email it was stated that staff could not follow the traffic/trip generation <br />information you provided, in large part because there is no exhibit to reference for context. <br />Therefore, it is believed that the traffic data was not considered with the roadway design <br />requirements. The project was revised to meet the commercial roadway standard. <br /> <br />e. Request to maintain design as proposed: <br /> <br />Maintain the proposed turn lane and taper lengths as shown on the project. Lengthening <br />the turn lanes will impact lot layout, ROW, and require preliminary plat amendment. <br /> <br />Stantec has calculated the recommended storage lengths for the right turn lanes on Linora <br />Avenue at Stillwater Way and Stillwater Boulevard. The calculations followed the <br />recommendations for storage lengths at unsignalized intersections as presented in the <br />MnDOT Road Design Manual section 5-3.01.03 on page 5-3(2).
