TERESA McCLISH, COMMUNITY DEVELOPMENT DIRECTOR
By: JON M. ANSOLABEHERE, DEPUTY CITY ATTORNEY
SUBJECT: CONSIDERATION OF INTRODUCTION OF AN ORDINANCE
AMENDING SECTIONS 16.04.070 AND 16.44.050 OF THE ClTY OF
ARROYO GRANDE MUNICIPAL CODE REGARDING FLOODPLAIN
MANAGEMENT; LOCKI'ION - CITYWIDE; APPLICANT - ClTY OF
ARROYO GRANDE
DATE: SEPTEMBER 11,2012
RECOMMENDATION:
It is recommended the City Council introduce an ordinance amending Sections
16.04.070 and 16.44.050 of the City of Arroyo Grande ("City") Municipal Code regarding
floodplain management.
IMPACT ON FINANCIAL AND PERSONNEL RESOURCES:
No financial impact is projected.
BACKGROUND:
The National Flood lnsurance Program ("NFIP") is a Federal program which was
enacted to mitigate flood losses through national community enforced building and
zoning requirements. The NFIP provides federally backed flood insurance protection for
property owners whose communities, such as the City of Arroyo Grande, participate in
the NFIP program. The NFIP program is administered by the Federal Emergency
Management Agency ("FEMA").
The Planning Commission reviewed the proposed Ordinance at a regular meeting on
August 21, 2012. At that time, the Commission passed a Resolution recommending the
Council adopt the Ordinance as prepared by staff.
ANALYSIS OF ISSUES:
On May 16, 2012, FEMA sent a letter to the City indicating that it has prepared a Flood
lnsurance Study ("FIS") and has issued a new Flood lnsurance Rate Map ("FIRM")
identifying the Special Flood Hazard Areas ("SFHA") located within the City. FEMA
requires, as a condition of continued eligibility in the NFIP, that the City's floodplain

management regulations comply or exceed the standards set forth in the Code of
Federal Regulations ("CFR"), Title 44, Section 60.3(d).
On May 11, 2012, FEMA issued its review of the City's Municipal Code regarding
compliance with the current Federal standards for storm water management. As a result
of this review and subsequent discussions between the City and FEMA staff, certain
amendments to the City's Municipal Code are required in order for the City to remain
eligible for the NFlP program. The proposed Ordinance is based on the model language
prepared by the California Department of Water Resources and brings the City's
floodplain management regulations into compliance with 44 CFR 60.3(d). More
specifically, this Ordinance:
Defines certain terms specific to floodplain management including definitions
for basement, development, expansion to an existing manufactured home
park or subdivision, lowest floor, new manufactured home park or
subdivision, recreational vehicle and special flood hazard area;
Amends the City's current floodplain management definitions to be consistent
with 44 CFR 60.3(d);
Adds findings of fact regarding the impacts of inadequately regulated
floodplain management; and
Amends the permit application to require additional site information such as
location of storage materials, location of water and sanitary utilities and
grading.
ALTERNATIVES:
'The following alternatives are provided for the Council's consideration: - Introduce the attached Ordinance as recommended; - Modify and introduce the Ordinance; - Do not introduce the Ordinance; and - Provide direction to staff.
ADVANTAGES:
The City will remain eligible with the NFlP program.
DISADVANTAGES:
'There are no disadvantages identified.

1. The flood hazard areas of the City of Arroyo Grande are subject to
periodic inundation which results in loss of life and property, health
and safety hazards, disruption of commerce and governmental

relief, and impairment of the tax base, all of which adversely affect
the public health, safety and general welfare.
2. These flood losses are caused by uses that are inadequately
elevated, floodproofed, or protected from flood damage. The
cumulative effect of obstructions in areas of special flood hazards
which increase flood heights and velocities also contributes to flood
losses.
SECTION 4. Arroyo Grande Municipal Code Section 16.44.050.E.l is hereby amended
in its entirety to read as follows:
1. Establishment of Development Permit. A development permit shall be obtained
before any construction or other development, including manufactured homes, within
any area of special flood hazard established in subsection D(2) of this section.
Application for a development pemrit shall be made on forms furnished by the
floodplain administrator. The applicant shall provide the following minimum
information:
a. Plans in duplicate, drawn to scale, showing :
