Environmental Rules in Lancaster, CA

If you live in Lancaster or are thinking about moving there, environmental rules are one of those things you probably won't think about until they affect you directly. Lancaster has 5 specific rules on the books covering different aspects of environmental rules, and some of them might surprise you.

Flood Zones

Lancaster regulates construction inside FEMA-mapped areas of special flood hazard under Municipal Code Article III of Chapter 17.40. No structure or land may be built, extended, converted or altered in a flood hazard area without full compliance, and violations are a misdemeanor enforced by the floodplain administrator.

Key details: Governing map: FIRM dated January 6, 1982. Underlying study: FIS dated July 6, 1981. Compliance required: Before any construction/alteration. Violation classification: Misdemeanor. Records location: 44933 North Fern Avenue, Lancaster.

Building or altering a structure in a special flood hazard area without complying with Article III, including any violation of a permit condition, is a misdemeanor under Sec. 17.40.170.C. Citywide, Municipal Code Sec. 1.12.020 sets the general misdemeanor penalty at up to a $1,000 fine, up to six months in the Los Angeles County Jail, or both, with each day of a continuing violation a separate offense.

Flood Elevation Requirements

New construction and substantial improvements in a Lancaster special flood hazard area must have the lowest floor, including any basement, elevated to or above the base flood elevation, with the elevation certified by a registered engineer or surveyor and filed with the floodplain administrator.

Key details: Elevation standard: Lowest floor at/above base flood elevation. AO zone minimum: 2 feet above grade if no depth listed. Certification required: Registered engineer or surveyor. Filed with: Floodplain administrator. Base flood defined as: 1% annual chance flood.

Failing to elevate a new structure or substantial improvement to the certified base flood elevation, or building without the required engineer/surveyor certification on file with the floodplain administrator, is a misdemeanor under Sec. 17.40.170.C, punishable citywide under Sec. 1.12.020 by up to a $1,000 fine, up to six months in county jail, or both, with continuing violations charged per day.

Defensible Space

For landscape projects in fire-prone parts of Lancaster, Section 8.50.090(A)(1)(j) requires the design plan to address fire safety, including a defensible space around any building "per Public Resources Code Section 4291(a) and (b)," and to avoid fire-prone plants and highly flammable mulch, referring designers to the local fuel modification plan guidelines.

Key details: Trigger: New/rehab landscape projects in fire-prone areas. State standard cited: Public Resources Code Section 4291(a),(b). Design duty: Avoid fire-prone plants and flammable mulch. Coordinated with: Local fire authority's fuel modification plan guide. Permit trigger size: 500 sq ft new / 2,500 sq ft rehab.

A landscape design plan for a fire-prone-area project that skips the required defensible-space and fire-safety elements can be rejected at plan check, and Section 8.50.050 lets the city set penalties for noncompliance with the landscape documentation package before the project receives its permit or design review approval.

Erosion Control

Lancaster bars anyone who owns or controls land from disturbing its surface, through excavating, grading, leveling, cultivating, or removing vegetation, in a way that causes dust emission or wind erosion under Municipal Code Section 8.16.030. Violators must control erosion with fencing, vegetation, or water and face a misdemeanor punishable by up to $500 and six months in jail.

Key details: Governs: Excavating, grading, leveling, land disturbance. Watering standard: Moist to 1-inch soil depth. Sites 5 acres or less: Tanker or on-site sprinkler. Sites over 5 acres: On-site sprinkler required. Max penalty: $500 fine, 6 months jail.

Violating any provision of Chapter 8.16 is a misdemeanor under Section 8.16.070, with each day the condition continues charged as a separate offense; conviction carries a fine of up to $500, up to six months in county jail, or both. The city engineer can also order work halted mid-project under Section 8.16.060 until adequate dust and erosion controls are restored, independent of any criminal penalty.

Stormwater Management

Lancaster bans dumping trash, debris, or any material into stormwater drainage facilities, public or private, under Municipal Code Section 13.04.020. Owners of property containing a private drainage channel must also keep it clear of trash, debris, and vegetation that could block water flow. Violations are misdemeanors punishable by up to a $1,000 fine or six months in county jail.

Key details: Dumping ban: No trash or debris in any drainage facility. Penalty: Up to $1,000 fine or 6 months jail. Applies to: Public and private drainage facilities/channels. Drainage fee program: Master plan of drainage adopted Nov. 16, 1992. Fee trigger: New dwelling units or added impervious area.

Section 13.04.030 makes any violation of the drainage chapter a misdemeanor, punishable by a fine of not more than one thousand dollars, imprisonment in county jail for not more than six months, or both, and each day a violation continues, such as a blocked channel left unremediated, counts as a separate offense. The city can pursue this alongside the drainage-fee conditions attached to any tentative map or parcel map approval.

This is not one of those rules that cities tend to ignore. Lancaster actively enforces its stormwater management requirements.
