Patrick Trudgeon Re: Preliminary Plat - Alpine Woods April 5, 2004 Page 2 The approved improvements to CR 57 for the Alpine Acres Plat on the east side of CR 57 include a northbound right turn lane and a southbound [eft turn lane at Sodium Avenue. These plans were approved prior to the submittal of the Alpine Woods Plat and the proposed local roadway on the west side of CR 57 associated with this plat. However, now with this development of Alpine Woods, the CR :57 roadway improvements will have to be modified at this time to include both northbound and southloound CR 57 left, thru and right turn lanes at Sodium Avenue. Additionally, a southbound CR :57 right turn lane will need will be required to be created at 153~d Lane NW. An engineering plan review fee will apply to this project (estimated at $3:50.00-$600.00). The costs associated with the design and construction of the turn lanes shall be the responsibility of the City/developer. For your information and use, we have attached a concept plan for the turn lane construction (see attached). Because a permit for right turn lane and bypass lane construction on CR :57 at 153~d Lane NW has alreads; been issued to the contractor for the Alpine Acres plat, that permit will need to be temporarily suspended and modified until revised engineering plans are submitted and approved by this department which include the necessary plan changes associated with the need for NB and SB .left, thru and right turn lanes (in lieu of the ¢onstrnction of a SB CR 57 bypass lane at 153~d Lane NW). Please contact Andrew Witter, Construction Services Engineer, for further information regarding the engineering plan review process. Calculations must be submitted along with a grading and erosion control plan that delineates the drainage areas for this site. The post-developed rate/volume of runoff shall not exceed the pre-developed rate/volume of runoff for the 10- year, critical design storm. Please submit the drainage calculations, grading and erosion control plans, and turn lane construction plans along with the ACHD Design Requirements Checklist for County Highway modifications (copy attached) and the applicable engineering plan review fee to Mr. Witter for his review and approval. If the City wishes to meet with county staff to discuss any of these county highway modifications prior to the submittal of formal engineering plans, we would be happy to do so. It should be noted that residential land use adjacent to high~vays usually results in complaints regarding traffic noise. Traffic noise at this location could exceed Noise Standards established by the U.S. Department of Housing and Urban Development, and the Minnesota Pollution Control Agency. Anoka County Policy regarding new developments adjacent to existing County highways prohibits the expenditure of highway funds for noise mitigation measures. The City and/or Developer should assess the noise situation and take any action deemed necessary to minimize associated impacts at this site from any traffic noise. A permit for work within county right of way is required and must be obtained prior to the commencement of construction (pe,'mit for Work Within County R/W = $110.00). License Permit Bonding, methods of construction, design details, work zone traffic control, restoration requirements and follow-up inspections are typical elements of the permitting process. Contact Roger Butler, Traffic Engineering Coordinator, or Josie Scott, Traffic Engineering Technician, for further information regarding the permit process. Installation of any necessary permanent traffic control devices within the county right of way for this proposed development will be coordinated, installed, and maintained by this department as part of the permit process. If any pavement marking removals on CR 57 are required in conjunction with this project, they will be the responsibility of the Developer. Thank you for the opportunity to comment. Feel free to contact me if you have any questions. Sin.c, erely, . Jane K.
