(Ord. 3544 § 1.1, 1979; Ord. 5231 § 1 (part), 2013; Ord. 5444 § 1, 2021)
(a) 
The flood hazard areas of the City are subject to periodic inundation which results in loss of life and property, health and safety hazards, disruption of commerce and governmental services, extraordinary public expenditures for flood protection and relief, and impairment of the tax base, all of which adversely affect the public health, safety and general welfare.
(b) 
These flood losses are caused by the cumulative effect of obstructions in areas of special flood hazards which increase flood heights and velocities, and when inadequately anchored, damage uses in other areas. Uses that are inadequately floodproofed, elevated or otherwise protected from flood damage also contribute to the flood loss.
(Ord. 3544 § 1.2, 1979; Ord. 5231 § 1 (part), 2013; Ord. 5444 § 1, 2021)
It is the purpose of this chapter to promote the public health, safety and general welfare, and to minimize public and private losses due to flood conditions in specific areas by provisions designed:
(a) 
To protect human life and health;
(b) 
To minimize expenditure of public money and costly flood control projects;
(c) 
To minimize the need for rescue and relief effort associated with flooding and generally undertaken at the expense of the general public;
(d) 
To minimize prolonged business interruptions;
(e) 
To minimize damage to public facilities and utilities such as water and gas mains; electric, telephone and sewer lines; streets and bridges located in areas of special flood hazard;
(f) 
To help maintain a stable tax base by providing for the sound use and development of areas of special flood hazard so as to minimize blight resulting from future flood;
(g) 
To ensure that potential buyers are notified that property is in an area of special flood hazard; and
(h) 
To ensure that those who occupy the areas of special flood hazard assume responsibility for their actions.
(Ord. 3544 § 1.3, 1979; Ord. 5231 § 1 (part), 2013; Ord. 5444 § 1, 2021)
In order to accomplish its purposes, this chapter includes methods and provisions:
(a) 
Restricting or prohibiting uses which are dangerous to health, safety and property due to water or erosion hazards or in flood heights or velocities;
(b) 
Requiring that uses vulnerable to floods, including facilities which serve such uses, be protected against flood damage at the time of initial construction;
(c) 
Controlling the alteration of natural floodplains, stream channels, and natural protective barriers, which help accommodate or channel floodwaters;
(d) 
Controlling filling, grading, dredging and other development which may increase flood damage; and
(e) 
Preventing or regulating the construction of flood barriers which will unnaturally divert floodwaters or which may increase flood hazards in other areas.
(Ord. 3544 § 1.4, 1979; Ord. 5231 § 1 (part), 2013; Ord. 5444 § 1, 2021)

A general and temporary condition of partial or complete inundation of normally dry land areas from:
(1) 
The overflow of inland or tidal waters.
(2) 
The unusual and rapid accumulation or runoff of surface waters from any source.
(3) 
Mudslides (i.e., mudflows) which are proximately caused by flooding as defined in subsection (b) of this definition and are akin to a river of liquid and flowing mud on the surfaces of normally dry land areas, as when earth is carried by a current of water and deposited along the path of the current.
(b) 
The collapse or subsidence of land along the shore of a lake or other body of water as a result of erosion or undermining caused by waves or currents of water exceeding anticipated cyclical levels or suddenly caused by an unusually high water level in a natural body of water, accompanied by a severe storm, or by an unanticipated force of nature, such as flash flood or an abnormal tidal surge, or by some similarly unusual and unforeseeable event which results in flooding as defined in subsection (a) of this definition.
"Floodplain"
means any land area susceptible to being inundated by water from any source. See "Flood or flooding."
"Floodplain Administrator"
means the community official designated by title to administer and enforce the floodplain management regulations.
"Floodplain management regulations"
means the zoning ordinances, subdivision regulations, building codes, health regulations, special purpose ordinances (such as floodplain ordinance, grading ordinance and erosion control ordinance) and other application of police power. The term describes such state or local regulations, in any combination thereof, which provide standards for the purpose of flood damage prevention and reduction.
"Floodproofing"
means any combination of structural and nonstructural additions, changes, or adjustments to structures which reduce or eliminate risk of flood damage to real estate or improved real property, water and sanitary facilities, structures, and their contents.

"Functionally dependent use"
means a use which cannot perform its intended purpose unless it is located or carried out in close proximity to water. The term includes only fish hatchery facilities, docking facilities, port facilities that are necessary for the loading and unloading of cargo or passengers, and ship building and ship repair facilities, and does not include long term storage or related manufacturing facilities.
"Habitable floor"
means any floor usable for living purposes, which include working, sleeping, eating, cooking or recreation, or a combination thereof. A floor used only for storage purposes is not a "habitable floor."
"Highest adjacent grade"
means the highest natural elevation of the ground surface prior to construction next to the proposed walls of a structure.
"Historic structure"
means any structure that is:
(a) 
Listed individually in the National Register of Historic Places (a listing maintained by the Department of the Interior) or preliminarily determined by the Secretary of the Interior as meeting the requirements for individual listing on the National Register;

An unfinished or flood resistant enclosure, usable solely for parking of vehicles, building access or storage, in an area other than a basement area, is not considered a building's lowest floor; provided, that such enclosure is not built so as to render the structure in violation of the applicable non-elevation design requirements of this chapter found at BMC § 17.60.300(b).
"Manufactured home"
means a structure, transportable in one (1) or more sections, which is built on a permanent chassis and is designed for use with or without a permanent foundation when connected to the required utilities. For floodplain management purposes the term "manufactured home" also includes park trailer, travel trailers, and other similar vehicles placed on a site for greater than one hundred eighty (180) consecutive days. For insurance purposes the term "manufactured home" does not include park trailers, travel trailers, and other similar vehicles.
"Manufactured home park or subdivision"
means a parcel (or contiguous parcels) of land divided into two (2) or more manufactured home lots for rent or sale.
"Mean sea level"
means, for purposes of the National Flood Insurance Program, the vertical datum to which base flood elevations shown on a community's Flood Insurance Rate Map are referenced.
"New construction"
means structures for which the "start of construction" commenced on or after the effective date of the ordinance codified in this chapter.
"New manufactured home park or subdivision"
means a manufactured home park or subdivision for which the construction of facilities for servicing the lots on which the manufactured homes are to be affixed (including at a minimum, the installation of utilities, the construction of streets, and either final site grading or the pouring of concrete pads) is completed on or after August 5, 1979, the effective date of floodplain management regulations adopted by the community.
One Hundred (100) Year Flood.
See "Base flood."
"Reasonably safe from flooding"
means development that is designed and built to be safe from flooding based on consideration of current flood elevation studies, historical data, high water marks and other reliable date known to the community. In unnumbered A zones where flood elevation information is not available and cannot be obtained by practicable means, reasonably safe from flooding means that the lowest floor is at least two feet above the highest adjacent grade.
"Recreational vehicle"
means a vehicle built on a single chassis, that is four hundred (400) square feet or less when measured at the largest horizontal projection, designed to be self-propelled or permanently towable by a light duty truck, and is designed primarily not for use as a permanent dwelling but as temporary living quarters for recreational, camping, travel, or seasonal use.
"Start of construction"
includes substantial improvements, and means the date the building permit was issued, provided the actual start of construction, repair, reconstruction, placement or other improvement was within one hundred eighty (180) days of the permit date. The "actual start" means the first placement of permanent construction of a structure on a site, such as the pouring of slab or footings, the installation of piles, the construction of columns or any work beyond the stage of excavation; or the placement of a manufactured home on a foundation. Permanent construction does not include land preparation, such as clearing, grading and filling; nor does it include the installation of streets and/or walkways; nor does it include excavation for a basement, footings, piers, or foundation or the erection of temporary forms; nor does it include the installation on the property of accessory buildings, such as garages or sheds not occupied as dwelling units or not part of the main structure. For a substantial improvement, the "actual start of construction" means the first alteration of any wall, ceiling, floor, or other structural part of a building, whether or not that alteration affects the external dimensions of the building.
"Structure"
means a walled and roofed building including a gas or liquid storage tank that is principally above ground.
"Substantial damage"
means damage of any origin sustained by a structure whereby the cost of restoring the structure to its before-damaged condition would equal or exceed fifty (50) percent of the market value of the structure before the damage occurred.
"Substantial improvement"
means any repair, reconstruction, or improvement of a structure, the cost of which equals or exceeds fifty (50) percent of the market value of the structure:
(a) 
Before the improvement or repair is started; or
(b) 
If the structure has been damaged and is being restored, before the damage occurred. For the purposes of this definition "substantial improvement" is considered to occur when the first alteration of any wall, ceiling, floor, or other structural part of the building commences, whether or not that alteration affects the external dimensions of the structure.
The term does not, however, include either:
(a)
Any project for improvement of a structure to correct pre-cited existing violations of state or local health, sanitary, or safety code specifications which have been previously identified by the local code enforcement official and which are the minimum necessary to assure safe living conditions; or
(b)
Any alteration of a structure listed on the National Register of Historic Places or a state inventory of historic places.
"Variance"
means a grant of relief from the requirements of this chapter which permits construction in a manner that would otherwise be prohibited by this chapter.
"Water dependent"
means a structure for commerce or industry that cannot exist in any other location and is dependent on the water by reason of the intrinsic nature of its operations, including but not limited to fish hatchery facilities.
"Water surface elevation"
means the height, in relation to the vertical datum utilized in the applicable flood insurance study, of floods of various magnitudes and frequencies in the floodplains of coastal or riverine areas.

(Ord. 3544 § 4.4-1(3), 1979; Ord. 5231 § 1 (part), 2013; Ord. 5444 § 1, 2021)
In passing upon such applications, the City Council shall consider all technical evaluations, all relevant factors, standards specified in other sections of this chapter, and:
(a) 
The danger that materials may be swept onto other lands to the injury of others;
(b) 
The danger to life and property due to flooding or erosion damage;

The susceptibility of the proposed facility and its contents to flood damage and the effect of such damage on the individual owner;
(d) 
The importance of the services provided by the proposed facility to the community;
(e) 
The necessity to the facility of a waterfront location, where applicable;
(f) 
The availability of alternative locations for the proposed use which are not subject to flooding or erosion damage;
(g) 
The compatibility of the proposed use with existing and anticipated development;
(h) 
The relationship of the proposed use to the Comprehensive Plan and floodplain management program for that area;
(i) 
The safety of access to the property in times of flood for ordinary and emergency vehicles;
(j) 
The expected heights, velocity, duration, rate of rise and sediment transport of the floodwaters and the effects of wave action, if applicable, expected at the site; and

(Ord. 3544 § 4.4-1(4), 1979; Ord. 5231 § 1 (part), 2013; Ord. 5444 § 1, 2021)
Generally, variances may be issued for new construction and substantial improvements to be erected on a lot of one-half (0.5) acre or less in size contiguous and surrounded by lots with existing structures constructed below the base flood level, providing BMC § 17.60.180(a) through (k) have been fully considered. As the lot size increases beyond the one-half (0.5) acre, the technical justification required for issuing the variance increases.
(Ord. 3544 § 4.4-1(5), 1979; Ord. 5231 § 1 (part), 2013; Ord. 5444 § 1, 2021)
The City Engineer shall maintain the records of all appeal actions and report any variances to the Federal Insurance Administration upon request.
(Ord. 3544 § 4.4-1(7), 1979; Ord. 5231 § 1 (part), 2013; Ord. 5444 § 1, 2021)
(a) 
Variances may be issued for the reconstruction, rehabilitation or restoration of structures listed on the National Register of Historic Places or the State Inventory of Historic Places that will not preclude the structure's continued designation as a historic structure and the variance is the minimum necessary to preserve the historic character and design of the structure without regard to the procedures set forth in the remainder of this section.
(b) 
Variances shall not be issued within any designated floodway if any increase in flood levels during the base flood discharge would result.
(c) 
Variances shall only be issued upon a determination that the variance is the minimum necessary, considering the flood hazard, to afford relief.
(d) 
Variances shall only be issued upon:
(1) 
A showing of good and sufficient cause;
(2) 
A determination that failure to grant the variance would result in exceptional hardship to the applicant; and
(3) 
A determination that the granting of a variance will not result in increased flood heights, additional threats to public safety, extraordinary public expense, create nuisances, cause fraud on or victimization of the public as identified in BMC § 17.60.180, or conflict with existing local laws or ordinances.
(e) 
Any applicant to whom a variance is granted shall be given written notice that the structure will be permitted to be built with a lowest floor elevation below the base flood elevation and that the cost of flood insurance will be commensurate with the increased risk resulting from the reduced lowest floor elevation.
(f) 
Variances as interpreted in the National Flood Insurance Program are based on the general zoning law principle that they pertain to a physical piece of property; they are not personal in nature and do not pertain to the structure, its inhabitants, or economic or financial circumstances.
They primarily address small lots in densely populated residential neighborhoods. As such, variances from the flood elevations should be quite rare.
(g) 
Variances may be issued for nonresidential buildings in very limited circumstances to allow a lesser degree of floodproofing than watertight or dry floodproofing, where it can be determined that such action will have low damage potential, complies with all other variance criteria, except this section, and otherwise complies with BMC § 17.60.240.

Where elevation data is not available either through the Flood Insurance Study or from another authoritative source (BMC § 17.60.140(b)), applications for building permits shall be reviewed to assure that proposed construction will be reasonably safe from flooding. The test of reasonableness is a local judgment and includes use of historical data, high water marks, photographs of past flooding, etc., where available. Base flood elevation data and reference marks are generally provided throughout Bremerton and are indicated on Bremerton's flood insurance map. Failure to elevate at least two (2) feet above grade in these zones may result in higher insurance rates.
(Ord. 4103 § 4, 1987; Ord. 5231 § 1 (part), 2013; Ord. 5444 § 1, 2021; Ord. 3544 § 5.1-5, 1979)

(a) 
Be floodproofed so that below one (1) 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; and
(c) 
Be certified by a registered professional engineer or architect that the design and methods of construction are in accordance with accepted standards of practice for meeting provisions of this section based on their development and/or review of the structural design, specifications and plans. Such certifications shall be provided to the official as set forth in BMC § 17.60.140(c)(2).
(d) 
Nonresidential structures that are elevated, not floodproofed, must meet the same standards for space below the lowest floor as described in BMC § 17.60.300(b).
(e) 
Applicants floodproofing nonresidential buildings shall be notified that flood insurance premiums will be based on rates that are one (1) foot below the floodproofed level (e.g., a building constructed to the base flood level will be rated as one (1) foot below that level).
(Ord. 3544 § 5.2-2, 1979; Ord. 4103 § 7, 1987; Ord. 4965 § 5, 2006; Ord. 4233 § 2, 1989; Ord. 5020 § 4, 2007; Ord. 5231 § 1 (part), 2013; Ord. 5444 § 1, 2021)
Construction of new critical facilities shall be, to the extent possible, located outside the limits of the special flood hazard area (SFHA) one hundred (100) year floodplain. Construction of new critical facilities shall be permissible within the SFHA if no feasible alternative site is available. Critical facilities constructed within the SFHA shall have the lowest floor elevated three (3) feet above BFE or to the height of the five hundred (500) year flood, whichever is higher. Access to and from the critical facility should also be protected to the height utilized above. Floodproofing and sealing measures must be taken to ensure that toxic substances will not be displaced by or released into the floodwaters. Access routes elevated to or above the level of the base flood elevation shall be provided to all critical facilities to the extent possible.
(Ord. 5231 § 1 (part), 2013; Ord. 5444 § 1, 2021)
All manufactured/mobile homes in the floodplain to be placed or substantially improved on sites shall be elevated on a permanent foundation such that the lowest floor of the manufactured/mobile home is elevated one (1) foot or more above the base flood elevation and be securely anchored to an adequately anchored foundation system to resist flotation, collapse and lateral movement.
(Ord. 3544 § 5.2-3, 1979; Ord. 4965 § 6, 2006; Ord. 5020 § 5 (part), 2007; Ord. 5231 § 1 (part), 2013; Ord. 5444 § 1, 2021)
Recreational vehicles placed on sites in the floodplain are required to either:
(a) 
Be on the site for fewer than one hundred eighty (180) consecutive days; or
(b) 
Be fully licensed and ready for highway use, on wheels or jacking system, attached to the site only by quick disconnect type utilities and security devices, and have no permanently attached additions; or
(c) 
Meet the requirements for manufactured/mobile homes as found in BMC § 17.60.320.
(Ord. 5020 § 5 (part), 2007; Ord. 5231 § 1 (part), 2013; Ord. 5444 § 1, 2021)
Located within areas of special flood hazard established in BMC § 17.60.070 are portions of Gorst and Parish Creeks which are designated as floodways. Since the floodway is an extremely hazardous area due to the velocity of floodwaters which carry debris, potential projectiles, and erosion 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 or architect is provided demonstrating that encroachments shall not result in any increase in flood levels during the occurrence of the base flood discharge;
(b) 
If subsection (a) of this section is satisfied, all new construction and substantial improvements shall comply with all applicable flood hazard reduction provisions of BMC § 17.60.230 through § 17.60.320;
(c) 
Construction or reconstruction of residential structures is prohibited within designated floodways, except for:
(1) 
Repairs, reconstruction, or improvements to a structure which do not increase the ground floor area; and
(2) 
Repairs, reconstruction or improvements to a structure, the cost of which does not exceed fifty (50) percent of the market value of the structure either:
(i) 
Before the repair or reconstruction is started, or
(ii) 
If the structure has been damaged, and is being restored before the damage occurred. Work done on structures to comply with existing health, sanitary, or safety codes which have been identified by the Code Enforcement or Building Official and are the minimum necessary to assure safe living conditions shall not be included in the fifty (50) percent determination in subsection (c)(2) of this section;
(d) 
Manufactured/mobile homes are prohibited in designated floodways.
(Ord. 4233 § 3, 1989; Ord. 3544 § 5.3, 1979; Ord. 5020 § 6, 2007; Ord. 5231 § 1 (part), 2013; Ord. 5444 § 1, 2021)
In areas with base flood elevations (but a regulatory floodway has not been designated), no new construction, substantial improvements, or other development (including fill) shall be permitted within Zones A1-30 and AE on the community's FIRM, unless it is demonstrated that the cumulative effect of the proposed development, when combined with all other existing and anticipated development, will not increase the water surface elevation of the base flood more than one (1) foot at any point within the community.
