summary sheet. Alternate bids are prioritized such that bid alternate 1 should ideally be approved first, followed by bid alternate 2, and then bid alternate 3. This is primarily due to the proximity from other streets proposed to receive sealcoat improvements. Similar to last year, Dresser trap rock is proposed this year in lieu of granite rock chips due to anticipated project cost savings related to decreased availability of granite rock chips. Construction is proposed to be completed earlier in 2018 than in recent years. This should reduce the amount of loose rock observed after work is complete due to completing the work during warmer temperatures. Per the project specifications, work may begin on or after June 18th, crackseal and sealcoat work must be completed by August 3rd, and all sweeping and striping work must be completed by August 31st. Staff considered using smaller sealcoat rock, which several cities are using now in an attempt to reduce loose rock on the street surface following sweepings as much as practical. However, Staff would like to observe the effects of completing construction earlier in the year before shifting to the use of smaller rock. Staff will evaluate this further before designing the 2019 crackseal and sealcoat project. Staff also proposes to fog seal all cul-de-sacs included in the 2018 project. Numerous metro area cities fog seal over sealcoats in cul-de-sacs due to reported benefits including that the sealcoat looks newer longer, the life of the sealcoat is extended due to reduced loss of rock, and that fewer complaints are received regarding the amount of rock found in garages, homes and businesses after being tracked in on tires and the bottoms of shoes. Other metro cities now fog seal the existing pavement in cul-de-sacs without sealcoating first. Staff also proposes to try this on up to three cul-de-sacs in this year's project and to monitor the results to see if this approach is more cost-effective then fog sealing over new sealcoats in the long-term. Staff is not proposing to fog seal any linear street segments in 2018. This is because no benefits were observed by Staff upon fog sealing over newly sealcoated streets in Ramsey Meadows 21d Addition and the parking lot of Fire Station 1 in 2016, or in 2015 when fog seal was applied over several newly sealcoated street segments. Based on continued monitoring of these streets and the parking lot at Fire Station 1, Staff believes that the benefits for fog sealing linear street segments do not justify the cost. The final modification Staff is proposing this year is to require the contractor to provide a third sweeping of all sealcoated streets before striping. This will remove more loose rock before striping, and will potentially reduce one round of sweeping that City Staff completes following the project. During the last couple of years, Staff has swept sealcoated streets two to three times to remove loose rock upon receiving complaints from the public.
