Lynnwood code sections checked for this page
The state building-permit exemption for retaining walls covers a wall not over four feet from the bottom of its footing to its top, with no surcharge and no impounded Class I, II, or III-A liquid. LMC 16.04 adopts the building code, and that chapter’s text was not read for this page, so the city confirms the exemption for each wall. Grading is a separate permit. The Public Works grading checklist (file dated 12.2019) lists its triggers as a cut deeper than two feet, a cut slope steeper than 1.5 to 1, a fill above 50 cubic yards, a fill deeper than one foot, and a fill that would block a drainage channel. LMC 12.04.040 requires permits for construction, excavation, and other intrusions into the public right-of-way. LMC 13.40.055 adopts the state Stormwater Management Manual for Western Washington, and LMC 13.45.040 lists the discharges allowed into the storm system.
