CI-R OF SAN BERNARDQO - REQUQsT FOR COUNCIL ~ION STAFF REPORT l ~.. The City of San Bernardino is probably the only city in Southern California still making permanent repairs for excavations in the public right-of-way by utility companies, developers or private contractors. The ordinance was adopted many years ago because of below standard repairs made by "absentee" contractors who were unable to be contacted following their work. Since then, compacting equip- ment and asphalt materials have been developed that are in common usage and, if used properly, have little or no failure. Southern California Gas Company has requested a blanket excavation permit with all inspections and permanent repairs made by them or their contractors. This would be acceptable to the Public Services Department for all cuts up to 4' X 4'. There would be 'no change in procedures for any excavation larger than 16 square feet. At the end of each month Southern California Gas Company will submit a list of all locations where they have worked in the public right-of-way and made cuts 4' X 4' or less. The Street Inspector will inspect each site for compliance to the City of San Bernardino Municipal Code and if they are accepted will be billed at $10.00 each. If they fail to comply, Gas Company personnel will be notified. During calendar year 1984 2,326 Street Cutting Permits were issued of which a minimum of 80% were requested from the Gas Company. The majority of these called for excavations of 16 square feet or less. Under the blanket permit the Gas Com- pany would have indefinate responsibility for maintaining there cuts instead of the 30 days now required. With the high water table and high rate of failing street cuts the impact on maintenance and liability claims could be very notable. It should also have a strong impact on office personnel. 75.0264 rllllH Ul III , o o r-"''''''': f, 6 SOUTHERN CALIFORNIA gas COMPANY o o 155 So. "G" Street.

Notification of Excavation -ror notTflcatTonmf6--fheClty of all excavations made under the Blanket Permit, we propose a monthly report of all cuts (see attached). This listing identifies the excavation, type of material, and date of excavation. The Proposed Monthly Report of cuts would be used for Permit Billing. .!!.iJ1J~9. Presently the City identifies each excavation on the invoice by permit number. With a Blanket Permit, there would not be individual permit numbers, however, we could identify each excation with a numbering system on the proposed excavation report. It would be beneficial to the Gas Company if the billing invoices were prepared from completed excavation listings. This would improve the efficiency of the reconciliation process. Benefits a.
