This section shall not be construed to waive the requirements of the General Safety Orders of the Department of Industrial Relations of the State of California, or the provisions of California Civil Code Section 832 concerning the rights of coterminous owners as to excavations.
See Division 70, Article 1, Chapter IX of the LAMC for all grading, excavation and fill requirements.
Projects which disturb less than one acre of soil and are not part of a larger common plan of development which in total disturbs one acre or more, shall manage storm water drainage during contsruction in accordance with the California Green Building Standards Code (CALGreen), Chapter 4, Division 4.1.
Nothing contained in this section shall be construed to grant permission to use, construct or place a canopy over any street or public place without first obtaining the necessary permits from the Department of Public Works.
PROTECTION OF PEDESTRIANS
|HEIGHT OF CONSTRUCTION||DISTANCE FROM CONSTRUCTION TO LOT LINE||TYPE OF PROTECTION REQUIRED|
|8 feet or less||Less than 5 feet||Construction railings|
|5 feet or more||None|
|More than 8 feet||Less than 5 feet||Barrier and covered walkway|
|5 feet or more, but not more than one-fourth the height of construction||Barrier and covered walkway|
|5 feet or more, but between one-fourth and one-half the height of construction||Barrier|
|5 feet or more, but exceeding one-half the height of construction||None|
For SI: 1 foot = 304.8 mm.
- Barriers shall be provided with 2-inch by 4-inch (51 mm by 102 mm) top and bottom plates.
- The barrier material shall be boards not less than 3/4 -inch (19.1 mm) thick or wood structural panels not less than 1/4-inch (6.4 mm) thick.
- Wood structural use panels shall be bonded with an adhesive identical to that for exterior wood structural use panels.
- Wood structural use panels 1/4 inch (6.4 mm) or 5/16 inch (23.8 mm) in thickness shall have studs spaced not more than 2 feet (610 mm) on center.
- Wood structural use panels 3/8 inch (9.5 mm) or 1/2 inch (12.7 mm) in thickness shall have studs spaced not more than 4 feet (1219 mm) on center provided a 2-inch by 4-inch (51 mm by 102 mm) stiffener is placed horizontally at mid-height where the stud spacing is greater than 2 feet (610 mm) on center.
- Wood structural use panels 5/8 inch (15.9 mm) or thicker shall not span over 8 feet (2438 mm).
Covered walkways shall have a clear height of not less than 8 feet (2438 mm) as measured from the floor surface to the canopy overhead. Adequate lighting shall be provided at all times. Covered walkways shall be designed to support all imposed loads. In no case shall the design live load be less than 150 psf (7.2 kN/m2) for the entire structure.
Exception: Roofs and supporting structures of covered walkways for new, light-frame construction not exceeding two stories above grade plane are permitted to be designed for a live load of 75 psf (3.6kN/m2) or the loads imposed on them, whichever is greater. In lieu of such designs, the roof and supporting structure of a covered walkway are permitted to be constructed as follows:
- Footings shall be continuous 2-inch by 6-inch (51 mm by 152 mm) members.
- Posts not less than 4 inches by 6 inches (102 mm by 152 mm) shall be provided on both sides of the roof and spaced not more than 12 feet (3658 mm) on center.
- Stringers not less than 4 inches by 12 inches (102 mm by 305 mm) shall be placed on edge upon the posts.
- Joists resting on the stringers shall be not less than 2 inches by 8 inches (51 mm by 203 mm) and shall be spaced not more than 2 feet (610 mm) on center.
- The deck shall be planks not less than 2 inches (51 mm) thick or wood structural panels with an exterior exposure durability classification not less than 23/32 inch (18.3 mm) thick nailed to the joists.
- Each post shall be knee braced to joists and stringers by members not less than 2 inches by 4 inches (51 mm by 102 mm); 4 feet (1219 mm) in length.
- A curb that is not less than 2 inches by 4 inches (51 mm by 102 mm) shall be set on edge along the outside edge of the deck.
For excavations, adjacent property shall be protected as set forth in Section 832 of the Civil Code of California.
Prior to the issuance of any permit, which authorizes an excavation where the excavation is to be of a greater depth than are the walls or foundation of any adjoining building or structure and located closer to the property line than the depth of the excavation, the owner of the site shall provide the Department of Building and Safety with evidence that the adjacent property owner or owners have been given a 30-day written notice of the intent to excavate. This notice shall state the depth to which the excavation is intended to be made and when the excavation will commence. This notice shall be by certified mail, return receipt requested.
- The excavation exposes any adverse geological formations, which would affect the lateral support of a public way, an adjacent property or an adjacent structure.
- The excavation extends below a plane extending downward at an angle of 45 degrees from the edge of the public way or an adjacent property.
EXCEPTION: Normal footing excavations not exceeding two feet in depth will not be construed as removing lateral support.
- The excavation extends below a plane extending downward at an angle of 45 degrees from the bottom of a footing of an existing structure.
The slopes of excavations adjacent to an existing structure, an adjacent property or public way may exceed one horizontal to one vertical where either:
- A soil report recommending that the slope may be in excess of one to one has been approved by the Department and the Department of Public Works when the excavation is adjacent to a public way.
When justified by the soils engineer, the Department may approve the use of the proposed building and/or shoring to support an adjacent structure on an adjoining property in lieu of underpinning, provided:
- Evidence is submitted that the adjoining property owner has been notified in advance of the proposed excavation in compliance with Section 832 of the Civil Code of California.
- The owner of the site records a sworn affidavit with the Office of the County Recorder, which will inform future owners of the site that the lateral support of a portion of the building footings on the adjoining property is provided by the subterranean walls of the building on the site.
- Underpinning is designed to support adjacent structures, temporary shoring is designed to support the excavation, and plans are approved and permits are issued by the Department.
Temporary shoring shall be designed for an earth pressure equivalent to that exerted by a fluid weighing not less than 30 pounds (13 kg) per cubic foot plus all surcharge loads or as recommended by a soils engineer and approved by the Department.
Soils bearing values shall be those specified in Division 18, Article 1, Chapter IX of the LAMC or those recommended by a soils engineer and approved by the Department.
The design of the required temporary shoring and necessary underpinning shall include a sequence of construction and installation.
Allowable stresses used in the design of temporary shoring may be increased 33-1/3% for structural and reinforcing steel and 25% for wood. No increase will be permitted for concrete. Other values shall be those prescribed by this Code.
Structures under construction, alteration or demolition shall be provided with no fewer than one approved portable fire extinguisher in accordance with Section 906 and sized for not less than ordinary hazard as follows:
