SUBMITTED BY: Director of Public Works/City Eng'

REVIEWED BY: City hlanager~~ ~~~ (4/5ths Vote: Yes No X )
On Parch 17, 1987, Council adopted an ordinance revising the City's flood
plain regulations in accordance with instructions by the Federal Emergency
Management Agency (FEMA). The ordinance was forwarded to that agency for
review and comments have now been received. Those comments request minor
additional changes which are incorporated in the recommended modifications.
RECOMMENDATION: That Council adopt ordinance modifying Chapter 18.54 of the
Municipal Code.
BOARDS/COMMISSIONS RECOMMENDATION: Not applicable.
DISCUSSION:
$~equent to the adoption of revised flood plain regulations by Council in
~, 1987, we received a notice f rom the California Department of Water
Resources (DWR) that that agency had become responsible for the review of the
local regulations being modified to meet new Federal requirements. The
deadline for adoption by local agencies of new regulations had been extended
and DWR was going to accomplish their review.
We have now received the results of the DWR review. They suggest that three
additional definitions be included in Section 18.54.030 of the City ordinance
and that changes be made in Section 18.54.040.6, 1&. 54.060.A and 18.54.060.C.
These changes involve the substitution in two sections of the term "lowest
floor" for the term "first floor" and in providing an added restriction in
areas where Zones AO have been identified within the City. Zone AO is defined
as an area of 100-year shallow flooding where depths are between one and three
feet and average depths of inundation are shown, but no flood hazard factors
are determined.
No AO zones in the City have been found where the depth of inundation is
greater than one foot. This modified restriction will require the lowest
floor of a structure to be one foot above the highest adjacent grade rather
than one foot above the crown of the nearest street as is presently required.

In addition to the changes requested by the Department of Water Resources, we
have been advised that FEMA has provided for tFre "grandfathering" of existing
mobil@ home parks from elevation requirements. Language incorporating this
provision was printed in the Federal Register and has been reproduced as
Section 18.54.060. B.2 of the proposed ordinance.
This latter version has been reviewed by representatives of the Western
Niobilehome Association who have indicated their concurrence.
The proposed revised regulations are attached as an exhi bi t and are marked to
show the specific recornmended changes.
FISCAL IMPACT: None.
