Grading in designated hillside areas or in excess of 5,000 cubic yards (3825 m
3
) of either cut or fill, or a combination thereof, shall be performed in accordance with the approved grading plan prepared by a civil engineer, and shall be designated as “engineered grading”. Grading involving less than 5,000 cubic yards (3825 m3) in a non hillside area shall be designated “regular grading” unless the permittee chooses to have the grading performed as engineered grading, or the Superintendent of Building determines that special conditions or unusual hazards exist, in which case grading shall conform to the requirements for engineered grading.
(Title and Section Amended by Ord. No. 171,175, Eff. 7/25/96.)
EXCEPTION: Grading which is not connected with building site development may be conducted in hillside areas when the Department finds that such work enhances the physical stabilization of property, or is not detrimental to public health, safety or welfare, and is in conformity with the approved master plan for the area. A tentative tract or division of land map shall also not be required for such exempt grading.
91.7005.2. Building Foundations. (Amended by Ord. No. 185,587, Eff. 7/16/18.) Building foundations and temporary shoring shall be designed and constructed as specified in Division 4, Article 1.5, Chapter IX of the LAMC or in Division 18 and Division 33, Article 1, Chapter IX of the LAMC.

91.7006.5. Bonds in Hillside Areas Required. The Superintendent of Building may require bonds in such form and amounts as may be deemed necessary to assure that the work, if not completed in accordance with the approved plans and specifications, will be corrected to eliminate hazardous conditions.
91.7006.5.1. Surety Bond. (Amended by Ord. No. 171,939, Eff. 4/15/98.) Before a permit is issued for excavation or fill of 250 cubic yards (191.3 m3) or more of earth in a hillside area, the owner of the property shall file with the Department a bond for the benefit of the city. The bond shall be executed by the owner and a corporate surety authorized to do business in this state as a surety in an amount sufficient to cover the entire project.
EXCEPTION. Upon application by the owner, the Department may waive this requirement if:
1. The proposed grading is neither actually nor potentially hazardous;
2. The grading work performed is in compliance with a Department order; or
3. The applicant can substantiate, to the satisfaction of the Department, that the work under a grading permit will be fully executed.
91.7006.5.2. Cash Bond. In lieu of a surety bond, the owner may file a cash bond with the Department on the same terms and conditions and in an amount equal to that which would be required in the surety bond. The deposit may be in the form of negotiable United States securities in lieu of cash.
91.7006.5.3. Application of Bond to Adjacent Property. Where grading is required on property adjacent to the grading site under permit in order to complete a project satisfactorily, the owner of such adjacent property need not provide an additional grading bond if the original bond is of sufficient amount to include such additional grading.
91.7006.5.4. Conditions of the Bond. (Amended by Ord. No. 171,939, Eff. 4/15/98.) Every bond shall be conditioned such that the owner shall:
1. Comply with all applicable provisions of this Code and all other applicable laws;
2. Comply with all of the terms and conditions of the grading permit to the satisfaction of the Department;
3. Complete all of the work described by the permit, and the plans and specifications relating thereto, within the time limit specified in the permit. Upon application by the permittee, the Department, or the Board, in case an appeal is made to it pursuant to Section 98.0403 of the Los Angeles Municipal Code, may, for sufficient cause, extend the time specified in the permit, but no such extension shall release any surety on the bond.
4. Install temporary erosion control devices when required to do so by the provisions of this Code.
91.7006.5.5. Period and Termination of Bond. The term of each bond shall begin on the date of filing and shall remain in effect until the work is completed to the satisfaction of the Department or until replaced by a new bond in the event of a change of ownership. In the event of failure to complete the work and/or failure to comply with all of the conditions and terms of the permit, the Department may order some or all of the work to be completed to correct any hazardous conditions. The surety executing such bond, or such deposit, shall continue to be firmly bound under a continuing obligation for the payment of all necessary costs and expenses that may be incurred or expended by the city in causing any and all of such required work to be done and that said surety or the depositor assents to any lawful extension of time within which to construct and complete such work. Such costs shall include an amount equal to the cost to the city of administering the contract and supervising the work required. In the case of a cash bond, the deposit, or any unused portion thereof, shall be refunded to the depositor upon completion of the work to the satisfaction of the Department. The Department may release or exonerate the bond under appropriate conditions when the public health and welfare is not jeopardized.
91.7006.5.6. New Ownership. (Amended by Ord. No. 171,939, Eff. 4/15/98.) In the event of change of ownership during grading, the new owner shall secure a new grading permit and post a new bond to ensure completion of the grading.
91.7006.5.7. Amount of Bond. (Amended by Ord. No. 171,939, Eff. 4/15/98.) The amount of the bond shall be based on the number of cubic yards of material in either excavation or fill, whichever is the greater amount, and in addition shall include the cost of all drainage or other protective devices such as, but not limited to retaining walls, as may lawfully be required. That portion of the bond valuation covering the cost of excavation or fill shall be computed as follows:
250 to 10,000 cubic yards $1,000, plus $1.00 per cubic yard
10,001 to 100,000 cubic yards $11,000, plus 50 cents per cubic yard for each additional cubic yard in excess of 10,000
Over 100,000 cubic yards $56,000, plus 35 cents per cubic yard for each additional cubic yard in excess of 100,000
For SI: 1 cubic yard = 0.765 m3
91.7006.5.8. Installment Refunds. When a substantial portion of the required grading work has been completed to the satisfaction of the Department, and when the completion of the remaining grading work, site development or planting is delayed, the Department may accept the completed portion of the grading work and consent to the proportionate reduction of the bond to an amount estimated to be adequate to ensure completion of the grading work, site development or planting remaining to be performed. Only one such reduction shall be considered for each bond posted.
91.7006.5.9. Entry Upon Premises. The Department, the Board of Public Works, the surety company, or their duly authorized representative, shall have access to the premises described in the permit for the purpose of inspecting the progress of the work.
In the event of default in the performance of any terms or conditions of the permit, the surety or any person employed or engaged in the person’s behalf shall have the right to go upon the premises to complete the required work, including the installation of temporary erosion control devices.
Should the permittee or the surety fail to perform the work described by the permit and the plans and specification relating thereto or required by any applicable law, and it is determined by either the Department or the Board of Public Works that the public health, safety or general welfare is endangered by such failure, the Department, the Board of Public Works, or the representative of either may enter upon the premises to perform all or any part of such work, including the installation of temporary erosion control devices.
It shall be unlawful for the owner or any other person to interfere with the ingress and egress from such premises of any authorized representative or agent of any surety company or the city engaged in the work ordered by the Department or the Board of Public Works.
91.7006.6. Consent of Adjacent Property Owner. (Amended by Ord. No. 185,587, Eff. 7/16/18.) Whenever any excavation or fill requires entry onto adjacent property for any reason, the permit applicant shall obtain the written consent of the adjacent property owner or the owner’s authorized representative, and shall file a copy of said consent with the Department before a permit for such grading work may be issued. The signature on such written consent shall be notarized.
In the event contours on adjacent properties are permanently changed, structures or drainage devices are added or modified, and/or the work done requires a grading permit under LAMC Subdivision 91.106.1.2, a separate permit shall be required for each such affected adjoining property in addition to the consent letter. Furthermore, the adjacent property owner shall acknowledge their consent on plans showing such work. The consent letter will not be required if the adjoining owner obtains a grading permit.
91.7006.7. Limitation of Export and Import.
91.7006.7.1. Export-import Defined. (Amended by Ord. No. 171,939, Eff. 4/15/98.) As used in this division, the term “export” and its derivatives shall be defined as the earth, brush or similar materials transported from a grading site. The term “import” and its derivatives shall be defined as earth, brush or similar materials transported to a grading site.
91.7006.7.2. General Conditions. (Amended by Ord. No. 171,939, Eff. 4/15/98.)

(Amended by Ord. No. 185,587, Eff. 7/16/18.)
91.7008.1. Civil Engineer. The civil engineer shall provide professional inspection within such engineer’s area of technical specialty, which shall consist of observation and review as to the establishment of line, grade and surface drainage of the development area. If revised plans are required during the course of the work, they shall be prepared by the civil engineer.
Upon completion of hillside tract grading, grading work in excess of 5,000 cubic yards (3825 m3) of either cut or fill, or a combination thereof, and other grading work if deemed warranted by the Department, the civil engineer or land surveyor responsible for the design shall submit a dated as-graded plan to the Department for approval of all work covered by the grading permit(s) and shall include the following:
l. The plan shall be no more than one-inch equals 40 feet scale (25 mm equals 12 192 mm scale)and shall show the locations of streets, pads, slopes, structures, pertinent elevations, original contours and finished elevations, and other pertinent information required to accurately show the as-graded condition.
2. The plan shall bear the signature of the design civil engineer or land surveyor which shall certify the engineer or surveyor has inspected the site, prepared the as-graded plans and that the work within the engineer’s or surveyor’s area of responsibility was done in accordance with the final approved grading plan.
91.7008.2. Soils Engineer. The soils engineer shall provide professional inspection within such engineer’s area of technical specialty, which shall include observation during grading and testing for required compaction. The soils engineer shall provide sufficient observation during the preparation of the natural ground and placement and compaction of the fill to verify that such work is being performed in accordance with the conditions of the approved plan and the appropriate requirements of this division. Revised recommendations relating to conditions differing from the approved soils engineering and engineering geology reports shall be submitted to the owner, the Department and the civil engineer.
The soils engineer, at the completion of hillside tract grading, grading work in excess of 5,000 cubic yards (3825 m3) of either cut or fill, or a combination thereof, and other grading work if deemed warranted by the Department, shall submit a final report. The final report shall include:
1. The soil engineer’s professional opinion of the suitability of the fill material and their placement, and the ability of the natural materials to support the compacted fill without excessive settlement of the fill or potential damage to structures erected thereon;
2. The results of all in-place density tests;
3. A statement that all subdrains were inspected prior to backfill;
4. A statement to the effect that the soils engineer has inspected all cuts and fills and that in the soil engineer’s opinion they meet the design requirements; and
5. All locations of the in-place density tests, retaining walls, subdrains and cut/fill slopes shall be shown on a plot plan which may be referenced to a dated as-graded plan prepared by the design civil engineer or land surveyor.
91.7008.3. Engineering Geologist. The engineering geologist shall provide professional inspection within such geologist’s area of technical specialty, which shall include professional inspection of the bedrock excavation to determine if conditions encountered are in conformance with the approved report. Revised recommendations relating to conditions differing from the approved engineering geology report shall be submitted to the soils engineer and the Department. (Amended by Ord. No. 186,488, Eff. 12/27/19.)
For hillside tract grading, grading work in excess of 5,000 cubic yards (3825 m3) of either cut or fill, or a combination thereof, and other grading work if deemed warranted by the Department, geologists shall submit periodic in-grading inspection reports at intervals determined by the Department. In addition, the engineering geologist at the completion of grading shall submit a final geological report stating that the geologist had maintained the required in-grading inspection, the recommendations of their pregrading report(s) have been followed, that in their professional opinion all known adverse geologic conditions have been corrected or provided for, future adverse geologic conditions are not anticipated, and all lots or sites are geologically suitable and safe for construction.
The final report shall include the geologist’s certification that the geologist has inspected all cut slopes and sidehill fill placement areas prior to placement of fill. The engineering geologist shall also certify that all subdrain placement areas were inspected prior to installation of the subdrains. The final report shall be referenced to a dated as-graded plan prepared by the design civil engineer or land surveyor.
91.7008.4. Grading Contractor. For hillside tract grading, grading work in excess of 5,000 cubic yards (3825 m3) of either cut or fill, or a combination thereof, and other grading work if deemed warranted by the Department, the grading contractor shall submit in a form prescribed by the Superintendent of Building a statement of conformance to said as-built plan and the specifications.
91.7008.5. Transfer of Responsibility. If, for any reason, the civil engineer, the soils engineer, or the engineering geologist of record is terminated during the progress of the grading work, that engineer or geologist, and the owner, shall immediately notify the Department in writing.
Such transfer of responsibility may result in temporary delays in the grading operations until satisfactory arrangements are made to assure the Department that competent professional supervision is provided. The new professional(s) shall submit to the Department a letter of responsibility that the previous professional’s designs, reports and recommendations have been reviewed and all provisions of the Department required as conditions of the grading permit will be complied with during the course of the work.
91.7008.6. Owner. (Amended by Ord. No. 185,587, Eff. 7/16/18.) The owner shall be responsible for the work to be performed in accordance with the approved plans and specifications and in conformance with the provisions of this Code, and the owner shall engage consultants, if required, to provide professional inspections on a timely basis. The owner shall provide a Registered Deputy Grading Inspector as required by LAMC Section 91.1704. The owner shall act as a coordinator between the consultants, the contractor and the Superintendent of Building. In the event of changed conditions, the owner shall be responsible for informing the Superintendent of Building of such change and shall provide revised plans for approval. The Department may require the submittal of a supplemental soils and/or geological report justifying such change.
91.7008.7. Notification of Noncompliance. (Amended by Ord. No. 186,488, Eff. 12/27/19.) If, in the course of fulfilling their respective duties under this division, the civil engineer, the soils engineer or the engineering geologist finds that the work is not being done in conformance with this division or the approved grading plans, the discrepancies shall be reported immediately in writing to the owner and to the Grading Division of the Department.
