MEMORANDUM TO: Jeremy Barnhart, Planning Manager FROM: Terry Maurer, City Engineer ~ DATE: September II, 2006 SUBJECT: Cranberry Ridge Addition File: 226-144P The following is a summary of the significant engineering issues as discussed at the staff review meeting and the meeting with the developers and their representative. 1. The roadway should be designed for a minimum of a 30 mph design speed, according to :MnDOT criteria indudingboth horizontal and vertical curves. 2. Enough information needs to be provided with the submittal package to indicate that Kennedy Street will be able to maintain a 30 mph design speed in turning from southerly to easterly direction to head toward Twin Lakes Road. The developers have significant information on the property to the south, the submittal package should also ensure that the road alignment will not impact wetlands that can be avoided. 3. A temporary cul-de-sac is shown at the end of Kennedy Street. City policy is that temporary cul-de-sacs are built to the full diameter and meet all the criteria of a permanent cul-de-sac, since many times these installations remain for a long period of time. There will be a requirement for the standard City of Elk River sign at the temporary cul-de-sac, indicating this is a future road extension. 4. As we discussed at the meeting with the developers and their representative, the grading plan should reflect adequate grading to ensure a minimum house pad and primary septic system location on every wooded lot. Then, based on this grading plan, a tree preserva~on plan can be constructed in accordance with what the Planning Department 15 requestIng. 5. I believe the developers have received the letter from Sherburne County Public Works regarding this plat. The resubmitted plans should show the appropriate improvements requested on County Road 33.
