Summary

Palmdale prohibits dumping trash, debris or vegetation into any natural or manmade storm drainage facility, public or private, under Municipal Code Chapter 12.32. Property owners with a private drainage channel on their land must also keep it clear, since the City Council found that blocked, overgrown facilities cause property damage and injury risk.

No person, firm or corporation shall place, deposit or leave any trash, debris or any other material upon or in any natural or manmade storm water drainage facility, publicly or privately owned, within the City. Nor shall any such person who is the owner or person in possession of any real property located within the City, upon which a privately owned natural or manmade storm water drainage facility or channel is located, shall permit or allow the deposit in the facility of any trash, debris, vegetation or other material which could, or might, block, in whole or in part, the flow of water therein. ... A violation of any provision of this chapter shall be deemed to be a misdemeanor, and shall be punishable by a fine of not more than $500.00, or by imprisonment in the County Jail for not more than six months, or both.

Full Breakdown

32 opens with City Council findings that 'numerous complaints have been made by residents of the City concerning public and private drainage facilities, natural and manmade, which are overgrown with vegetation and blocked by such weeds, debris and other material' and that regulation is 'necessary in order to eliminate such conditions' because 'damage to properties and possible injury to persons will result' otherwise. ' The duty therefore falls on dumpers directly and, separately, on property owners who allow blockage to accumulate on their own land, whether the material was dumped by them or simply left unmaintained.

The chapter applies citywide to both City-owned storm channels and privately owned drainage facilities and channels, and covers vegetation growth as well as trash and debris. Construction-phase stormwater pollution is handled separately through the City's NPDES permit and grading provisions in the Building Code.

Violations & Fines

Section 12.32.030 makes any violation of Chapter 12.32 a misdemeanor 'punishable by a fine of not more than $500.00, or by imprisonment in the County Jail for not more than six months, or both,' and treats each day a blocked or debris-filled drainage facility is left uncorrected as a separate offense, so fines can compound daily until the facility is cleared.

Frequently Asked Questions

Can I dump yard waste into a drainage channel behind my Palmdale property?
No. PMC Section 12.32.020 makes it unlawful to place, deposit or leave trash, debris or any other material in any natural or manmade storm water drainage facility, whether publicly or privately owned, anywhere in the City. This covers grass clippings, tree trimmings and other yard waste as much as construction debris.
Am I responsible for keeping a private drainage channel on my land clear?
Yes. Section 12.32.020 separately prohibits the owner or person in possession of property containing a privately owned drainage facility or channel from permitting or allowing trash, debris or vegetation to accumulate there in a way that could block the flow of water, regardless of who deposited the material.
What is the penalty for blocking a Palmdale drainage facility?
A violation of Chapter 12.32 is a misdemeanor punishable by up to a $500 fine, up to six months in County Jail, or both, under Section 12.32.030. Each day the blockage continues counts as a separate offense, so an uncorrected condition can generate a new violation and additional exposure every day it persists.
