A sealcoat program is a cost-effective tool to
extend the life of the street system, Sealcoating
emulsion followed immediately with an
beneficial because it:
streets is
.
Delays or eliminates further aging of pavement
Seals to provide a moisture barrier.

.
.
.
.
.
Sealcoating remains to be one of the most cost-effective
pavement management. It is estimated that a sealcoat
of pavement from three to five years at a fraction of the
rehabilitation or bituminous overlay projects. It is therefore cost effective to
sealcoat roadways when pavement distresses are fewer verses letting the
pavement deteriorate until major, costly rehabilitation .or reconstructionproj~cts
are required.
In conjunction with the Pavement Management Program, staff has reviewed the
City's street network and is recommending the streets shown on the attached map
to be sealcoated in 2008. Theestiriiated9()stfor thisproject is $220,000. The
cost includes prior street preparation work, traffic control and pavement markings
to match existing conditions. The project is proposed to be bid in February and
The City 01 Chanhassen · A growing community with clean lakes, quality schools, a charming downtown, thriving businesses, winding trails, and beautiful parks. A great place to live, work, and play.

This will reduce the need to reconstruct streets and will allow us to more closely match the life of streets to the utility lines that lie underneath
them. This will allow better coordination when we need to replace water and sewer lines with replacing roads.
