The KSD Group was engaged by KB Home in early 2007 to manage a major infrastructure improvement project on their behalf. As a condition of approval for their Mt. Eden Subdivision, the City of Hayward required offsite improvements to incorporate several streets that were formerly within unincorporated county limits. The Mt. Eden Benefit District was created to fund the work, with a firm budget of $9.2 million.

Most of the existing streets had to be widened, requiring right-of-way rights to be acquired from private land owners. Once granted, demolition and restoration work were completed on 111 private lots to install new public curb/gutters, sidewalks and street trees. The challenge was conforming to existing private driveways, walkways, and landscaping to the satisfaction of the land owners. The scope of work also included installing new storm, sewer, and water lines, new paving, street lights, traffic signals, and undergrounding most of the overhead utility lines on eight city streets.
