Based on this survey, City streets are <br />recommended for various treatments, which include reconstruction, overlay or sealing. Streets <br />that are in fairly good condition are recommended for sealing, which could be either slurry seal <br />or cape seal. The purpose of the sealing treatment is to prolong the life of the pavement. Slurry <br />seal is a mixture of asphalt emulsion and fine crushed aggregate. A cape seal is a combination of <br />a slurry seal applied on top of a chip seal, which is a coat of asphalt emulsion followed by a layer <br />of crushed rock. <br />The streets in the city were divided into four Asphalt Maintenance Areas, which allows <br />Engineering and Transportation staff to effectively coordinate with Public Works Services staff <br />to ensure an efficient use of resources to maintain City streets. The streets scheduled for this <br />project fall into the 2010 Asphalt Maintenance Area. <br />Stephen L. Hollister <br />City Manager <br />
