May 15, 2004 Assessment Hearing....... ............... ............................... ...Fall, 2004 Frequently Asked Questions: Q - How much is this project going to cost me? This Depends on what City Council has approved for the Rates and Fees Schedule for the current year. For the current year of 2004, the assessment rate is $2,400 per lot for a street reconstruction period. This amount can be prepaid up to 30 -days after the assessment hearing that is typically held in the fall, without any interest charges. If prepayment is not chosen, the assessment will be rolled into your property taxes usually over a five -year period at an interest rate that is 2 % higher than the City's bond rate for the project. Q - Will I always have access to my driveway? For the majority of the construction project a resident will have access to his /her driveway. However, if a concrete driveway or concrete curb & gutter is being replaced in front of your driveway, the City requires a 72 -hour curing time with no disturbance to the concrete during this time. There also may be short periods during the day where a resident might have to wait a couple of extra moments to get to his /her driveway. Frequently Asked Questions: Q - My driveway is being replaced, will it be put back the same as it was before? Your driveway will be replaced to as close as it was originally before construction began if it meets City Code. If your driveway does not meet City Code, your driveway will be replaced to the best of the City's ability to meet your requests and to stay within the City Code. Current City Code states maximum width of a residential driveway is 22' within public right -of -way. Q - Where will I be able to pick up my mail? The contractor at the start of construction will install temporary mailboxes and residents will be notified of the location. Also, all mailboxes will be replaced with new mailboxes as part of final restoration. Residents will be reminded to salvage their mailbox if they prefer to save their old one. Frequently Asked Questions: Q - How will the school bus pick up my children? The City will coordinate with the bus company to determine if an alternate pick- up location is required during construction. If a new location is required, the affected residents will be notified. Q - Will the contractor work in front of my house on weekends? The City of Rosemount has specified the following work hours: Monday - Friday 7:00 a.m. - 10:00 p.m. Saturday 8:00 a.m. - 5:00 p.m. No work on Sundays or Holidays Frequently Asked Ouestions: Q Whom may I contact if I have a question or a concern during the project? The City of Rosemount will send out a letter to all residents with contact names and phone numbers associated with the project prior to the beginning of construction. There will also be weekly updates with information on the City's web page www.ci.rosemount.mn.us or you can call Rosemount Public Works at 651- 322 -2022. Public Informational Meeting, January 8, 2004: Resident's Concerns Why are you reconstructing Damask Avenue if it doesn't need it? Looks can be deceiving and although it appears to the naked eye that Damask doesn't need repairing, it does. The PCI Rating for Damask is 40 and according to the PMP Recommendations, Damask is borderline between total reconstruct and overlay. The majority of the project area will have new storm sewer installed that will cut into the existing street, it is more feasible to fully reconstruct the street instead of overlay when utilities are being installed. Also, a better contract price is attained if only reconstructing streets instead of reconstructing and overlaying. How long will the project take? Assuming a typical Minnesota summer, the contractor should be completed with all work including final restoration and final bituminous wear course by the end of September. Public Informational Meetinll cont' d: Are you going to fix the sanitary sewer problems? A concerned resident that has had sanitary backup problems in the past was questioning if the project would eliminate these problems. The area of the project in question was researched and it was found that most recently two sanitary backups occurred in 2002. The cause of the backups was from twigs, branches, leaves and other debris that was put into the manholes through the manhole covers that had a hole in the middle of them. The City has remedied the problem by replacing all existing manhole covers with solid lids and a backup has not occurred since. The City also televised the concerned residents sanitary service to investigate the possibilities of a service line deficiency. The televising revealed some minor issues in the private service line that the resident will be repairing.
