Document Description
Los Angeles County is proposing a resolution to establish the Topanga UUD along Old Topanga Canyon Road and Topanga Canyon Boulevard. The proposed project would relocate overhead utility distribution lines along Old Topanga Canyon Road and Topanga Canyon Boulevard. Those utility lines that currently cross aerially over Topanga Creek at the bridge just north of Topanga Canyon Boulevard on Old Topanga Canyon Road would be placed alongside the bridge via a utility conduit. All other utility lines, would be placed underground primarily within the existing right-of-way. The proposed Topanga UUD is approximately 3.6 acres. The proposed project would remove 28 existing utility poles, which is comprised of approximately 2,100 linear feet of overhead utility distribution conductor lines.
