The provisions of Section 3304 of IBC are adopted by reference with the following modifications:
1. Add a new Section 3304.2 to read:
"3304.2 Drainage across property lines.
Drainage across property lines shall not exceed that which existed prior to site work. Excess or concentrated drainage shall be contained on site or directed to a permitted drainage facility. Erosion of the ground in the area of discharge shall be prevented by installation of nonerosive down drains or similar devices."
2. Add a new Section 3304.3 to read:
"3304.3 Fencing of excavation work.
Where excavation work to any depth will occur within 5 feet (1524 mm) of a walkway on public or private property, temporary fencing, not less than 4 feet (1219 mm) in height shall be erected around the area of excavation. Such fencing shall be adequately supported to prevent it from collapsing due to wind. Where the depth of excavation work exceeds 30 inches (762 mm), the fencing shall meet the requirements for guards in Chapters 10 and 16. No person shall remove or open a required fence except to allow necessary delivery and removal of materials, tools and equipment or passage of workers, inspectors or other persons whose presence is required at the site."
