Grading Plan Review and Approval
The project submittal will be reviewed by the drainage & grading plan check engineer for completeness and compliance with applicable codes including LID (Low Impact Development) requirements (see required codes below). In addition, grading plan approval typically requires approvals from agencies such as Planning, LA County Soils & Geology, Fire Department, and Coastal Commission. The applicant must submit plans themselves to the various agencies for their project on their own. Once the grading plan has been approved and if proposed grading is associated with a building permit, the grading permit must be obtained first, then rough grade obtained prior to obtaining the building permit. The grading permit will not be finalized and any bond will not be released until all permit related to the grading work is finalized by the inspector.
Grading projects must comply with the following codes and manuals:
- 2014 County of Los Angeles Building Code (Title 26) Based on the 2013 California Building Code and the 2012 International Building Code
- 2014 County of Los Angeles Residential Code (Title 30) Based on the 2013 California Residential Code and the 2012 International Residential Code
- 2014 County of Los Angeles Green Building Standards Code (Title 31) Based on the 2013 California Green Building Standards Code
- 2014 County of Los Angeles Environmental Protection (Title 12)

Submittal Requirements for Building Drainage Review & Approval
Plans must show proposed scope of work and include details of existing and proposed drainage for the site LID compliance may apply see Low Impact Development Standards Manual at http://dpw.lacounty.gov/ldd/lib/fp/Hydrology/Low%20Impact%20Development%20Standards%20Manual.pdf and if so, must be shown on the plan. Submit plans, 1 set at a minimum, to the Local Building & Safety Office for building drainage review (see local office locations & hours) or submit online.
LID Review and Approval
LID may apply per Title 12 Environmental Protection for both drainage plans and drainage and grading plans. If it is applicable, plans must show the required Best Management Practices (BMPs) and supporting documentation must be provided. See the LA County LID Standards Manual 2014 for guidance: http://dpw.lacounty.gov/ldd/lib/fp/Hydrology/Low%20Impact%20Development%20Standards%20Manual.pdf
Grading Permit Inspection
Once the grading permit is issued, a pre-grade meeting will be required prior to start of grading with the inspector, owner, grading contractor, civil and soils consultant. Construction Best Management Practices must be installed at this time. Additional grading inspections will be required before and during construction, and at the end of construction of the site. Your contractor and project consultants will be required to provide certifications (see Building & Safety forms & publications at: http://dpw.lacounty.gov/bsd/publications/index.cfm) of on-site work for rough grading and final grading stages. Approval of LA County Soils and Geology is typically required to obtain rough grade and in order to obtain building permits.
