Chapter 17.32 — (PL) POTENTIAL LIQUEFACTION OVERLAY DISTRICT

The purpose of the Potential Liquefaction Hazard (PL) Overlay District is to protect life and property in the City of Lake Elsinore from the effects of seismic activity in areas subject to liquefaction and ground lurching. This hazard overlay district implements the policies of the Lake Elsinore General Plan to promote the public health, safety and general welfare of its citizenry.

The purpose of this overlay is also to ensure the review of all proposed discretionary projects within identified potential liquefaction areas by professional soil engineers and the incorporation of sitespecific recommendations and mitigation measures as conditions of approval. (Code 1987 § 17.08.010; Ord. 772 § 17.08.010, 1986)

In any base district where the district symbol is followed by, as part of such symbol, parenthetically enclosed letters "PL," thus "(PL)," the additional requirements, limitations and standards contained in this section shall apply. The district symbol shall constitute the "base district" and the (PL) suffix shall constitute the "overlay district." In the event of conflicting provisions of such a combined district, the requirements of the PL district shall take precedence over the requirements of the base district. Uses permitted by the PL district must in each instance be in compliance with those uses permitted by the applicable base district regulations and associated standards. (Code 1987 § 17.08.020; Ord. 772 § 17.08.020, 1986)

Uses permitted in this overlay district shall include:

• A. Horticultural uses.

(Code 1987 § 17.08.030; Ord. 772 § 17.08.030, 1986)

• A. All uses permitted in the base district, including ordinarily permitted uses and uses subject to a conditional use, are subject to a conditional use permit and potential liquefaction hazard analysis in accordance with the procedures set forth in LEMC § 17.32.060 .

• B. Conditions of approval shall include such recommended mitigation measures as deemed appropriate to carry out the intent and purpose of this chapter.

• (Code 1987 § 17.08.040; Ord. 772 § 17.08.040, 1986)

No project application to which LEMC § 17.32.040 applies shall be deemed complete and/or filed nor be accepted for filing until all the final potential hazard liquefaction analysis is completed for

presentation to the City. (Code 1987 § 17.08.050; Ord. 772 § 17.08.050, 1986)

• A. Prior to the commencement of a proposed discretionary project, which is located either wholly or partially within any area zoned (PL), requiring the approval of any development permit or tentative map, the proponent of the project shall prepare, or cause to be prepared, a draft potential liquefaction hazard analysis, and submit the draft analysis to the Director of Community Development, or his designee, shall determine the number of copies of the draft analysis required to be submitted. Before completing the draft potential liquefaction hazard analysis, the preparer shall consult directly with any person whom or organization which the preparer believes will be concerned with the geologic and soils hazards in the project area and with other public agencies involved in carrying out or approving the project.

• B. The draft potential liquefaction hazard analysis shall contain the following information, in form as approved by the Director of Community Development, pertaining to the entirety of the proposed project:

  1. The analysis shall be a combined in-depth geologic and soils investigation prepared by a licensed civil engineer qualified in soil mechanics and registered in the State of California.

  2. Required geologic and soils investigations shall include sufficient detail and recommendations to adequately address the potential liquefaction hazard and suggest specific mitigation measures and conditions of approval to lessen this hazard to an acceptable level.

(Code 1987 § 17.08.060; Ord. 772 § 17.08.060, 1986)

The proponent of any project for which a potential liquefaction hazard analysis is to be prepared shall be required to pay a fee to defray the City's cost of evaluating and analyzing that potential liquefaction hazard analysis. The fees required to defray the City's costs shall be established by a resolution of the City Council.

(Code 1987 § 17.08.070; Ord. 772 § 17.08.070, 1986)
