BACKGROUND On June 19, 2007, City Council approved and awarded a construction contract to Vanguard Construction in the total contract amount of $247,850. The subject project consists of the replacement of 3,300 L.F. of curb and gutter, 4,300 S.F. of sidewalk/driveway, and installation of five access ramps on Black Avenue, Division Street, Saint Mary Street, Bonita Avenue, and Stoneridge Drive. Typically, the curb and gutter project is initiated prior to the City repaving a street. Prior to the start of work, the street maintenance crews do minor street repairs, followed by the concrete contractor who replaces curb, gutter and adjacent sidewalks that are damaged. Then, a separate contractor repaves the street with asphalt pavement. Prior to the curb and gutter concrete contractor beginning work, City maintenance crews were performing pavement patch repairs and removing asphalt in the curb and gutter pan on Black Avenue and Division Street, when some latent problems on Division Street were discovered.

Typically, in resurfacing a street, 1 to 2 inches of asphalt next to the curb and gutter is ground out and refilled with new pavement that matches the pre-existing elevations at the curb and gutter level (See Figure 1). However, in some instances, instead of grinding out the old pavement, the entire street width is overlaid extending the pavement into the curb and gutter pan (see figure 2). Each time the street is resurfaced, additional pavement is added to the gutter pan and the curb height gets Page 2 of 3
