How Livermore Handles Landscaping Rules: A Practical Guide

Livermore maintains 129 local ordinances across all categories, and 7 of those deal specifically with landscaping rules. Here is a breakdown of what the city actually requires, what is prohibited, and where Livermore falls on the strict-to-permissive spectrum compared to other cities.

Water Restrictions

Livermore follows California Water Service and Zone 7 drought stages, plus permanent SWRCB rules: no runoff, no hosing hardscape, watering before 9 AM / after 6 PM.

Key details: Water Provider: Cal Water / Zone 7. State Rules: SWRCB permanent. Watering Hours: Before 9 AM / after 6 PM. Runoff: Prohibited. Rain Lockout: 48 hours.

Cal Water issues warnings then surcharges; city code enforcement can issue administrative fines $100-$500 per offense for repeat violators.

Livermore is more permissive than most cities when it comes to water restrictions. That said, there are still limits.

Tree Removal & Heritage Trees

Livermore requires a City tree permit before anyone removes, relocates, or encroaches into the protected zone of a protected tree, defined by trunk circumference thresholds that vary by property type. Removing without one is an infraction with mandatory replacement or a $5,000 flat fee per tree.

Key details: Permit trigger: 60-inch CBH (single-family) or 24-inch CBH (other uses). Permit validity: 90 days, unless tied to development approval. Unpermitted removal penalty: Infraction; $5,000 flat fee per tree if unvalued. Minimum replacement: Two 15-gallon trees per removed tree (single-family). Reviewing department: Public Works or Community Development.

Removing, relocating, or encroaching into a protected tree's zone without a valid permit, or violating permit conditions, is an infraction abated under LMC Title 1 per LMC § 12.20.280. The City may immediately suspend any tree or development permit on the property until compliance is shown, and the violator must still obtain a permit and mitigate the loss: replacement trees valued per LMC § 12.20.230(B), or a flat $5,000 fee per tree if value cannot be determined. Enforcement officers may enter property to inspect trees and issue citations under LMC § 12.20.260; interfering with an enforcement officer is separately prohibited under LMC § 12.20.270.

Compared to other cities, Livermore takes a harder line on tree removal & heritage trees. The enforcement and penalty structure reflects that.

Composting

Livermore's municipal code does not set backyard compost bin standards, but it carves home composting out of the general ban on storing or dumping waste on private property. Under LMC § 8.08.060(C) and § 8.08.090(C), residents may keep leaves, grass clippings, and food waste on-site for home composting or mulching without violating the solid waste chapter.

Key details: Storage-ban exemption: LMC § 8.08.060(C). Dumping-ban exemption: LMC § 8.08.090(C). Bin/design standards: none set by code. Permit required: no. Definition source: LMC § 8.08.020.

Home composting itself carries no penalty because §§ 8.08.060(C) and 8.08.090(C) exempt it from the general storage and dumping bans. But a compost pile that is not managed and instead festers into standing waste, attracts rodents, or spills onto neighboring property can be cited separately as a public nuisance under LMC § 8.14.030, which covers vegetation likely to harbor rodents or vermin and general accumulation of waste, triggering the abatement and administrative-citation process in Chapter 8.15.

The rules around composting in Livermore lean permissive, but that does not mean anything goes.

Rainwater Harvesting

Livermore encourages rain barrels, rain gardens and catchment systems in landscape plans under LMC § 13.25.180, but bars connecting any rainwater catchment system to the domestic water supply and requires applicants to check with the water district on whether a permit is required before installing one.

Key details: Soil requirement: Friable soil required in all planted areas. Recognized BMPs: Rain barrels, rain gardens, catchment systems. Hard rule: Catchment systems cannot connect to domestic water. Before installing: Must contact water district about permit needs. Related ordinance: Chapter 7.74 LMC governs stormwater discharge.

Connecting a rainwater catchment system to the domestic water supply violates LMC § 13.25.180(D)(7) outright, and skipping the required water-district check on permit needs under § 13.25.180(D)(8) can also draw enforcement. Chapter 13.25 violations, including noncompliant stormwater retention design or unfriable soil under § 13.25.180(C), allow the City to suspend any development permit already issued for the property under § 13.25.220 until compliance is demonstrated to the Public Works Director.

The rules around rainwater harvesting in Livermore lean permissive, but that does not mean anything goes.

Native Plants

Livermore's landscape design plan rules require every water-efficient project to keep total plant water use under the maximum applied water allowance, and LMC § 13.25.080(A)(1)(a) names protecting native species and choosing local native plants as the lead compliance method the City accepts.

Key details: Water budget: Plant water use must stay under maximum applied allowance. Top method: Protecting native species and natural vegetation. Preference: Local native plants named specifically. ETAF cap: 0.55 residential / 0.45 nonresidential. Sign-off: Licensed architect or landscape architect certifies plan.

A landscape design plan that cannot show its plant selections keep estimated water use under the maximum applied water allowance, including one that skips native or water-conserving species without another qualifying method, fails Chapter 13.25 review. LMC § 13.25.220 lets the City suspend any development permit already issued for the property until compliance is demonstrated to the Public Works Director's satisfaction.

Weed Ordinances

Livermore abates noxious weeds and overgrown vegetation under Gov Code §39560 and PRC §4291, targeting fire fuels on vacant lots and hillside parcels.

Key details: Authority: Gov Code §39561. Weed List: Alameda County Ag Comm.. Fire Overlap: PRC §4291. Common Weeds: Star thistle, medusahead. Enforcement: LPFD annual program.

Tree Trimming

Livermore regulates trimming of street and heritage trees through the Public Works Department; private-property trees generally don't require permits unless protected.

Key details: Street Trees: Public Works permit. Heritage Oaks: Permit if >25% canopy. Private Trees: No permit routine. Utility: PG&E line clearance. Neighbor Branches: Trim to line only.

The Bottom Line

Compared to many U.S. cities, Livermore gives residents more room on landscaping rules. 3 of the 7 rules here are rated permissive. But permissive does not mean unregulated. There are still requirements, and the city does enforce them when violations are reported.
