STORM DRAIN IMPROVEMENTS PROJECT IN RIALTO AVENUE FROM RANCHO AVENUE TO PENNSYLVANIA
AVE (SD04-09) PER PLAN NO. 10311.
Justification
Break Out and Remove Existin~ R.C.P. Stub
The contractor excavated to beginning construction of the storm drain and discovered the
2-1 existing storm drain R.C.P. stub to be laid at a different angle than the proposed storm
drain. It was necessary to remove the existing R.C.P. stub.
Chip Existin~ Manhole to Flowline
During construction, a 6-inch duct bank was discovered. The elevation of the duct bank
2-2 did not leave ample clearance to allow the new storm drain to be installed. The contractor
was required to chip down the main line storm drain to provide ample clearance beneath
the duct bank to allow storm drain lateral to be installed.
Install Storm Drain System for Palm A venue Fire Station
2-3 To install the storm drain lateral into the mainline storm drain after the existing stub was
removed and the flow line was lowered, it was necessary to pour a concrete color at the
manhole to create a proper tic-in.
Break out Concrete Obstruction
2-4 During excavation for the storm drain lateral, a manmade concrete obstruction was
encountered. It was necessary to remove the obstruction to proceed with the installation
of the storm drain.
Provide Slack in Verizon Duct
A Verizon duct was encountered during construction of the storm drain lateral. To
2-5 provide clearance over the duct, the contractor was required to expose 40 feet of the
Verizon duct to provide enough slack to lower the duct and provide clearance for the
storm drain lateral.
Remove 6-inch Steel Pipe
2-6 An unidentified 6-inch steel pipe was encountered in the S.D.C. trench. The contractor
was directed to remove the 6-inch steel line to provide ample room for the storm drain
trench.
Remove Temp. A.C.
2-7 During construction, the Public Services crew was paving in front of the entrance of the
Fire Station. The sewer and water trench were backfilled with temporary A.C. pavement.
To expedite the paving project, the storm drain contractor was directed to remove the
temp. A.C. pavement.
Re-Route Street Light Conduit
2-8 The existing streetlight conduit ran through the proposed storm drain catch basin. It was
necessary to re-route the streetlight conduit.
