MEMORANDUM DATE: December 29, 2014 TO: Ryan Streff, City Planner FROM: Terry Maurer, Public Works Director John Anderson, Assistant City Engineer SUBJECT: Valentine Cove This memo is intended to summarize the discussion we had on December 29 th , with City staff and our City Attorney, Joel Jamnik, regarding some of the engineering issues regarding the proposed Valentine Cove development. Particular issues concerning staff revolve around right-of-way width, street width and street section. Based on discussion in this meeting we have come up with the following recommendations: 1. The street right-of-way is shown at a 50 feet width rather than the 60 foot width required by City ordinance. Given that the proposed public street is a short cul-de- sac serving eight lots and will never be extended further the 50 foot right-of-way will be adequate. With a required 28 foot wide street section the 50 foot right-of- way will still leave eleven foot boulevards on each side for small utilities and snow storage. 2. The cul-de-sac street diameter is shown at 92 feet rather than the ordinance required 100 foot diameter. The cul-de-sac right-of-way is shown at the required 120 foot diameter. The smaller cul-de-sac width of 92 feet is adequate for the turning of street maintenance equipment, emergency vehicles and school buses and should be adequate for the project. 3. In exchange for the above two deviations from City ordinance we would recommend that the street section constructed in Valentine Cove include a 24 inch sub cut filled with select granular borrow and draintile. This will help to ensure the longevity of street section well into the future. This is particularly important given that the proposed street is singularly loaded (lots only on the north side of the street) and sometime in the future will need improvements that are typically assessed to the abutting properties. By including the 24 inch sub cut, select granular fill and drain tile in the original construction it will help to ensure that future assessed improvements deal with rejuvenation of the bituminous surface and not reconstruction of the entire street section. 4. Other issues mentioned in the John Anderson memo dated December 23, 2014 dealing with issues regarding the construction plans we assume will be addressed by the developer’s engineer. If you have any questions regarding these issues, please contact either John or Terry.
