Existing code did not specify what was acceptable and submittals ranged from sketches to blueprints.
Proposed ordinance requires that the drawing must be generated by the City’s GIS system and will provide both a map and an address list for the area and include the 1500 ft. notification distance and 500 ft. preblast survey distance.
Existing code requires 15 days to elapse after notification of pre-blast survey before blasting may commence. Utilities were not specifically addressed.
Proposed ordinance permits blasting to commence when pre-blasts are completed or specifically declined and utility companies have responded or the 10 day waiting period for response has elapsed. Blasting may also commence after 20 days has elapsed.
Existing code permits the contractor to conduct seismographic monitoring
Proposed ordinance requires an independent firm provide monitoring within 500 feet of structures, other buildings or pipelines. It permits the contractor to conduct monitoring for structures greater than 500 feet from the blast site.
Existing code does not specifically provide for outside technical review.
Proposed ordinance requires a blasting expert, hired by the contractor, review and approve the blast plan whenever blasting occurs within 500 feet of structures, other buildings and pipelines. The expert reports to the fire marshal and must have proof of liability insurance.
