V�V�414 "S Memo To :Mayor and City Council Members From :Ric Minetor, City Engineer/Director of Public Works Date :July 6, 1989 Subject :1989 Street Surface Treatment Project I have reviewed the pavement inventory system and determined that the 1989 surface treatment program should consist of chip sealing this summer and crack sealing this fall. Therefore, I am recommending bidding the chip seal project at this time; bids will be accepted until the morning of July 20th. A recommendation for award will be presented to Council at the regular meeting on July 24, 1989. The attached map and list of streets show the streets included in the proposed chip seal project. The list was deternit,ed by reviewing the type and severity of deficiency listed in the inventory. The selection was based on deficiencies which chip seal is an appropriate maintenance strategy. Otter streets in the City will be included in patching by city crews and in crack sealing this fall. It is necessary to crack seal in colder weather in order to fill the cracks when they are opened due to pavement shrinkage. Some streets may appear to be in worse condition than those selected for these programs. This is because a pavement management strategy bases maintenance on pavements that will benefit the most for the type of strategy selected. Some pavements are beyond the point where a simple surface treatment, crack seal, or minor patching are appropriate. These streets need surface rehabilitation, replacement or total reconstruction. The most economical approach is to keep these streets as serviceable as possible without major expenditures. At a future date, when they are not possible to keep serviceable, rehabilitation, replacement or reconstruction should be scheduled. I recommend that Council concur with the project as proposed, schedule the bid opening for July 20, 1989 at 9:00 a.m. and schedule the bid award for Monday, July 24, 1989.
