El Monte FAQ
Do I need a grading permit to level my backyard?
Generally not for minor landscape grading under 50 cubic yards on flat ground per CBC Appendix J Section J103. You will need a permit if you exceed that volume, cut/fill more than 5 ft, work on a slope steeper than 1:3, or your work changes drainage onto a neighbor's parcel.
Can my downspouts drain to the street?
Yes through an approved curb drain. El Monte requires drainage to be deposited in a concrete receptor and carried under the sidewalk through the curb into the gutter in a manner approved by the City Engineer - it may not flow over the sidewalk or parkway.
What if my neighbor's grading is flooding my yard?
Report it to El Monte Public Works/Code Enforcement. Grading that diverts surface water onto adjoining property violates the City Engineer's drainage approval and may be a private nuisance under California Civil Code Section 3479. The City can require corrective grading or revoke the permit.
Long Beach FAQ
Do I need a grading permit?
Generally required for earth-moving over 50 to 100 cubic yards or changes to existing drainage patterns. Small landscaping projects are usually exempt.
My neighbor changed their grading and water flows onto my property. What can I do?
Contact Long Beach code enforcement. Redirecting drainage onto neighboring properties violates most municipal codes. The neighbor may be required to restore proper drainage.
