BACKGROUND
The Orange County Sanitation District (OC San) owns 4,483 manholes throughout Orange County. Most of these manholes are in the public right-of-way. When cities or the county repave their streets, OC San and all other utility providers are responsible to adjust their access points, such as manholes, to the new street grade elevation.
RELEVANT STANDARDS
* Operate and maintain facilities to minimize impacts on surrounding communities, including odor, noise, and lighting
* Protect OC San assets
* Commitment to safety & reducing risk in all operations
PROBLEM
The City of Anaheim completed a street overlay project on Euclid Street, from Katella Avenue to La Palma Avenue, impacting 47 OC San manholes.

PROPOSED SOLUTION
