Subject 08001898 - 2610 S Dishman - Review Response
liqtrit'
The following are the review comments for the project proposal out at 2610 S Dishman from our
Floodplain Development Permit Reviewer. csr
After a review of the additional information submitted by the applicant and dated June 23, 2008, application #08-
001898 is still incomplete for the purpose of determining whether or not to issue a floodplain development permit
The new information did satisfy many of the requests in the initial incomplete response dated June 4, 2008.
However, the following items requested on June 4 are still missing and need to be included for a complete
application:
1. Information related to flood -proofing as requested under the floodplain ordinance subsection 21.30.070(2)(c) in
the June 4th incomplete response. It does not matter that the proposal is only to replace an existing structure.
According to the National Rood Insurance Program and 44 CFR 59.1 definitions: 'Substantial improvement°
means any reconstruction, rehabilitation, addition or other improvement to a structure, the total cost of which
equals or exceeds 50 percent of the market value of the structure before the start of construction of the
improvement If a structure meets the substantial improvement criterion it must be brought up to current floodplain
management standards.
2. The re -submittal also did not include the requested hydraulic analysis per the floodplain ordinance as described
under subsection 21.30.070(2)(d) in the June 4 incomplete response.
Upon submittal of this information, the application can be deemed complete which starts the formal
review process.

SVMC 21.30.070 A — Development Permit Required
A floodplain development permit is required for construction or development proposed
witthin any area of special flood hazard. The permit shall be for all structures including
manufactured homes, as defined in Appendix A, and for all development including fill
and other activities, also as defined in Appendix A.
SVMC 21.30.070 B — Applicattion for Development Permit
An application for a development permit shall be made on forms furnished by the City
and may include, but not be limited to, plans in duplicate drawn to scale showing the
nature, location, dimensions, and elevations of the area in question; existing or
proposed structures, fill, storage of materials, drainage facilities, and the location of the
foregoing.
Specifically, the following information is required:
1. Elevation in relation to mean sea level, of the lowest floor (including basement) of
all structures recorded on a current elevation certificate (FF 81-31) with Section B
completed by the local official;
2. Elevation in relation to mean sea level to which any structure has been flood -
proofed;
3. Certification by a registered professional land surveyor, engineer or architect that
the flood -proofing methods for any nonresidential structure meet the flood -
proofing criteria in SVMC 21.30.090(C)(2); and
4. Description of the extent to which a watercourse will be altered or relocated as a
result of proposed development.
SVMC 21.30.070 D — Duties and responsibilitties of the local administrator
Duties and responsibilities of the local administrator shall include, but not be limited to:
1. Review all development permits to determine that the permit requirements of
SVMC Title 21 have been satisfied.
2. Review all development permits to determine that all necessary permits have
been obtained from those federal, state, or local governmental agencies from
which prior approval is required.
3. Review all development permits to determine if the proposed development is
located in the floodway. If located in the floodway, assure that the encroachment
provisions of SVMC 21.30.090(C)(7) are met.
4. When base flood elevation data has not been provided (A and V Zones) in
accordance with SVMC 21.30.020, Basis for establishing areas of special flood
hazard, the floodplain administrator shall obtain, review, and reasonably utilize
any base flood elevation and floodway data available from a federal, state or
other source, in order to administer SVMC 21.30.090(C), Specific Standards, and
SVMC 21.30.090(C)(7), Floodways.
SVMC 21.30.090 — Provisions for flood hazard reduction
General standards are required in all areas of special flood hazard.
SVMC 21.30.090 C — Specific Standards
In all areas of special flood hazards where base flood elevation data has been provided
(Zones Al — 30, AH, and AE) as set forth in SVMC 21.30.020, Basis for establishing
areas of special flood hazard, or SVMC 21.30.070(D)(4) relating to use of other base
flood data, the following provisions are required:
SVMC 21.30.090 C 2 — Nonresidential Construction
New construction and substantial improvement of any commercial, industrial or other
nonresidential structure shall either have the lowest floor, including basement, elevated
one foot or more above the base flood elevation; or, together with attendant utility and
sanitary facilities, shall:
a. Be flood -proofed so that below one foot or more above the base flood
level the structure is watertight with walls substantially impermeable to
the passage of water;
b. Have structural components capable of resisting hydrostatic and
hydrodynamic loads and effects of buoyancy;
c. Be certified by a professional engineer or architect licensed in the state of
Washington that the design and methods of construction are in
accordance with accepted standards of practice for meeting provisions of
this subsection based on their development and/or review of the
structural design, specifications and plans;
d. Nonresidential structures that are elevated, not flood -proofed, must meet
the same standards for space below the lowest floor;
e. Applicants flood -proofing nonresidential buildings shall be notified that
flood insurance premiums will be based on rates that are one foot below
the flood -proofed level (e.g., a building flood -proofed to the base flood
level will be rated as one foot below).
SVMC 21.30.090 C 3 — Manufactured Homes
All manufactured homes in the floodplain to be placed or substantially improved shall be
elevated on a permanent foundation such that the lowest floor of the manufactured
home is elevated one foot or more above the base flood elevation and shall be securely
anchored to a permanent foundation system to resist flotation, collapse and lateral
movement; provided, however, that manufactured homes to be placed on substantially
improved sites in an existing manufactured home park or subdivision which has not
experienced substantial damage as a result of flooding shall be elevated so that either:
a. The bottom of the crawlspace of the manufactured home is elevated one
foot or more above the base flood elevation; or
b. The manufactured home chassis is supported by reinforced piers or other
foundation elements of at least equivalent strength that are no less than
36 inches in height above grade and be securely anchored to an
adequately anchored foundation system to resist flotation, collapse, and
lateral movement.
SVMC 21.30.090 C 7 - Floodways
Located within areas of special flood hazard are areas designated as floodways. Since
the floodway is an extremely hazardous area due to the velocity of flood waters which
carry debris, potential projectiles, and erosion potential, the following provisions apply:
a. Prohibit encroachments, including fill, new construction, substantial
improvements, and other development unless certification by a registered
professional engineer is provided demonstrating through hydrologic and
hydraulic analyses performed in accordance with standard engineering
practice that the proposed encroachment would not result in any increase
in flood levels during the occurrence of the base flood discharge.
b. Construction or reconstruction of residential structures is prohibited within
designated floodways, except for: (i) repairs, reconstruction, or
improvements to a structure which do not increase the ground floor area;
and (ii) repairs, reconstruction or improvements to a structure, the cost of
which does not exceed 50 percent of the market value of the structure
either: (A) before the repair, or reconstruction is started; or (B) if the
structure has been damaged, and is being restored, before the damage
occurred. Any project for improvement of a structure to correct existing
violations of state or local health, sanitary, or safety code specifications
which have been identified by the local code enforcement official and
which are the minimum necessary to assure safe living conditions or to
structures identified as historic places may be included in the 50 percent.
c. If the provisions of this section are satisfied, all new construction and
substantial improvements shall comply with all applicable flood hazard
reduction provisions of this section.
SVMC 21.30.100 — Additional requirements
A. In all storage areas designated on the FIRM, there shall be no net loss of flood
storage or infiltration capacity.
B. No development shall be allowed which removes flood storage volume unless an
equal volume of storage as defined by the pre -development ground surface and
the base flood elevation is provided in the immediate area of the proposed
development to compensate for the volume of storage which is lost (compensatory
storage). Excavation below the ground water table shall not constitute an equal
volume of storage.
C. No obstruction shall be permitted in any storage area which restricts or diminishes
flood water conveyance capacity or floodway characteristics.
