Chapter 14.18
INTERIM FIRE FLOW STANDARDS FOR GROUP A WATER SYSTEMS

Sections:

14.18.010 Applicability.

14.18.020 Definitions.

14.18.030 New residential development.

14.18.040 Existing residential development.

14.18.010 Applicability.

These interim standards shall be applied to all new or expanding Group A community water systems (as defined in WAC 246-290) only and will apply until final standards are adopted as part of a coordinated water system plan for Mason County.

(Ord. 46-07, Attach. A (part), 2007).

14.18.020 Definitions.

For the purposes of this chapter:

"Existing residential development" means and includes property that is currently developed, supplied by a water system and a service area has been delineated to accommodate the maximum number of lots/residences to be served by the system design.

"Expansion" means additions, extensions, changes or alterations to an existing source, transmission, storage or distribution facilities that will allow the system to increase in size its existing service area and/or number of approved service connections.

Exceptions:

(1) A system that connects new approved individual retail or direct service connections onto an existing distribution system within an existing service area; or

(2) A distribution system extension in an existing service area identified in a current and approved water system plan or project report.

"Group A water systems" means a public water system providing service such that it meets the definition of a public water system provided in the 1996 amendments to the Federal Safe Drinking Water Act (Public Law 104-182, Section 101, subsection b).

Group A water systems are further defined as:

"Community water system" means any Group A water system providing service to fifteen or more service connections used by year-round residents for one hundred eighty or more days within a calendar year, regardless of the number of people, or regularly serving at least twenty-five year-round (i.e., more than one hundred eighty days per year) residents.

(Examples of a community water system might include a municipality, subdivision, mobile home park, apartment complex, college with dormitories, nursing home, or prison.)

"Nested storage" means one component of storage is contained within the component of another.

"New residential development" means and includes improvements to vacant land, such as all activities associated with the subdivision of property (including short- and large-lot subdivisions), construction of new residential dwelling units (single or multi-family), mobile/manufactured home park or similar residential uses.

"Standby storage" means the volume of stored water available for use during a loss of source capacity, power, or similar short-term emergency.

The standby storage component or the fire suppression storage component, whichever volume is smaller, can be excluded from a water system's total storage requirement providing that such practice is not prohibited by: (1) a locally developed and adopted coordinated water system plan; (2) local ordinance; or (3) the local fire protection authority or county fire marshal (See WAC 246-290-235(4)).

Service Area Boundary. A service area boundary of a public water system holds within it (1) its existing service area [RCW 70.116.030 (6) and WAC 246-293-110 (11)] and (2) its future service area [WAC 246-293-110 (12)]. Generally, a public water system's service area encompasses those areas that are currently being provided service, as well as those areas where the public water system is planning on providing service in the future.

Purpose. Delineation of service areas helps to prevent overlapping or redundant services, which can be costly to the utility and its customers. Clear identification of areas of responsibilities allows for consistent and logical planning. The assumption is made that a utility has the ability to provide service in a timely and reasonable manner within its service area boundaries and is provided the right of first refusal. Service area boundaries are delineated during the development or revision of an ACWSP. Service areas that are larger than the system's existing service area allow for future system expansion.

14.18.030 New residential development.

(a) New Residential Development Without Alternative Measures to Reduce Flow Requirements. New residential developments with their own sources of public water supply shall have a minimum of one hundred twenty thousand gallons of water storage dedicated for fire suppression available at all times. This volume of storage shall be in addition to any volumes required by DOH for approval of a public water system. This standard comes from the International Fire Code (IFC) requirement of one thousand gallons per minute flow for one hundred twenty minutes.

(b) New Residential Development with Alternative Measures to Reduce Flow Requirements. Reductions in fire suppression storage or fire flow requirements may be allowed if the development has instituted certain measures that make it possible for reduced demands for fire suppression purposes. Such measures as density of development, types of construction, increased building setbacks could allow for reductions in the fire storage or needed fire flows. The Mason County fire marshal shall review any proposals for reductions in fire suppression capacity on a case-by-case basis prior to an approval for fire storage or flow reductions.

(c) Fire Hydrant Spacing Requirements. The hydrant spacing for all residential developments shall be in accordance with the IFC requirement of one hydrant for every five hundred feet, or less.

(d) Minimum Distribution System Pressures During Active Fire Suppression Activities. The State Department of Health requires that a minimum pressure of twenty PSI shall be maintained throughout the water distribution system under the hydraulic condition of concurrent maximum day flow plus fire flow. This minimum pressure shall apply at the point where the designed volume of equalizing storage and fire suppression storage has been depleted. See "chapter 246-290-230 (6) WAC - Distribution Systems" for this requirement (in the state drinking water system rules).

(e) Transmission Lines. Transmission lines shall meet the current minimum pressure requirements of WAC 246-290.

(f) Minimum Pipe Size. The IFC requires a minimum eight-inch diameter pipe for nonlooped lines, and six-inch diameter pipes for looped lines, for new or replacement distribution mains.

(g) New Residential Development with Variances for Residential In-House Fire Sprinkler Systems. Developments with ordinances, by-laws, or other governing controls requiring all residences to be constructed with internal fire sprinkler systems may have their fire suppression storage reduced to a minimum of sixty thousand gallons, in accordance with allowance proved by the IFC. Additional reductions are allowed for "FIREWISE" designs and/or use of alternate fire resistant construction materials. Conservation of water may also provide for additional reductions for fire suppression storage or the fire flow requirements. The Mason County fire marshal should be contacted on a case-by-case basis to see what levels of reduced fire storage may be associated with such elements as availability of emergency water sources, alternate emergency egress capacity, combustible materials management, and use of alternate construction materials.

(Ord. 46-07, Attach. A (part), 2007).

14.18.040 Existing residential development.

The requirements of the IFC, as given above, also apply to facility improvements or upgrades to Group A community water systems within existing residential developments, except as follows:

(1) System distribution main expansions or replacements shall be designed to meet the current minimum standards as outlined in WAC 246-290.

(2) Fire suppression storage shall be based on a minimum of five hundred gallons per minute (gpm) flow for thirty minutes duration, which equates to fifteen thousand gallons for fire protection, and is also consistent with stipulations in the State Water System Coordination Act. The minimum dedicated fire suppression storage volume at any time shall not be less than fifteen thousand gallons. This minimum would be in addition to other storage volumes required for public water systems under the state drinking water rules and design requirements.

(3) If water is provided from other sources for fire control purposes, the gallon requirements for fire storage requirement may be reduced by twenty-five percent.

(4) Draft fire hydrants may be permitted only with approval by the Mason County fire marshal.

(5) An additional twenty-five percent reduction in fire suppression storage may be granted for use of "FIREWISE" design throughout the development, and/or if alternate fire-resistant construction materials have been used for residential housing construction.

(6) Nested storage may be allowed; however, the Mason County fire marshal shall review all proposals for nested storage to ensure that under no conditions shall the volume of fire storage be reduced below a minimum of fifteen thousand gallons per five hundred gpm for thirty minutes (unencumbered).

(7) Expansion of an existing Group A community water system beyond the existing established service area shall be reviewed by the Mason County fire marshal and applicable area fire district to determine impacts and availability of water in the system to adequately serve additional connections.

Article I.
Statutory Authorization, Purpose, and Objectives

14.22.010 Statutory authorization.

The Legislature of the state of Washington has delegated the responsibility to local governmental units to adopt regulations designed to promote the public health, safety, and general welfare of its citizenry. RCW 36.70A.060 and RCW 36.70A.170 provides for the designation and regulation of frequently flooded areas, and Chapter 86.16 RCW provides for the administration of National Flood Insurance Program regulation requirements by local governments. This chapter as adopted and amended shall be known as the Mason County flood damage prevention ordinance.

(Ord. 87-08 Attach. A (part), § 1.1, 2008: Ord. 81-07, Attach. A, § 1.1, 2007: Ord. 9-03, Attach. B8, § 1.1, 2003: Ord. 10-02, Attach. B, § 1.1, 2002: Ord. 16-00, Attach. B, § 1.1, 2000: Ord. 59-91, § 1.1, 1991).

14.22.020 Purpose.

(a) Background. The flood hazard areas of Mason County are subject to periodic inundation which can result 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. These flood losses could be exacerbated 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.

Mason County has prepared this flood damage prevention ordinance to implement comprehensive flood damage reduction measures that are necessary for public health safety and welfare and that allow property owners to protect their property. Additional information about the Skokomish River valley has been developed through recent studies, and such data is relevant to this chapter. Further studies in the Skokomish River floodplain are currently being undertaken under the authority of the Army Corps of Engineers.

(b) Purpose. It is therefore 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:

(1) To protect human life, health and property;

(2) To minimize expenditure of public money and costly flood damage control projects;

(3) To minimize the need for rescue and relief efforts associated with flooding and generally undertaken at the expense of the general public;

(4) To minimize prolonged business and farming interruptions;

(5) 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;

(6) 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 future flood blight areas;

(7) To ensure that potential buyers are notified that property is in an area of special flood hazard; and

(8) To ensure that those who occupy the areas of special flood hazard participate, along with government, in assuming responsibility for their actions.

(9) To allow individuals to protect their life, health, and property when it is done in accordance with all applicable laws and regulations.

(10) Implement applicable recommendations of Skokomish River Comprehensive Flood Hazard Management Plan.

(11) Provide for continued eligibility for National Flood Insurance Program.

(Ord. 87-08 Attach. A (part), § 1.2, 2008: Ord. 81-07, Attach. A, § 1.2, 2007: Ord. 9-03, Attach. B8, § 1.2, 2003: Ord. 10-02, Attach. B, § 1.2, 2002: Ord. 16-00, Attach. B, §§ 1.2, 1.3, 2000: Ord. 59-91, §§ 1.2, 1.3, 1991).

14.22.030 Methods of reducing flood losses.

In order to accomplish its purposes, this chapter provides regulatory methods and provisions for:

(1) Restricting or prohibiting uses which are dangerous to health, safety, and property due to water or erosion hazards, or which result in damaging increases in erosion or in flood heights or velocities;

(2) Requiring that uses vulnerable to floods, including facilities which serve such uses, be protected against flood damage at the time of initial construction;

(3) Controlling the alteration of natural floodplains, stream channels, and natural protection barriers, which help accommodate or channel floodwaters;

(4) Controlling filling, grading, and other development which may increase flood damage;

(5) Preventing or regulating the construction of flood barriers which will unnaturally divert floodwaters or may increase flood hazards in other areas;

(6) Controlling excessive erosion by constructing sound erosion control structures and obtaining appropriate permits and exemptions from all applicable local, state, and federal jurisdictions; and

(7) Implementing the recommendations of adopted flood hazard studies and plans.

(Ord. 87-08 Attach. A (part), § 1.3, 2008: Ord. 81-07, Attach. A, § 1.3, 2007: Ord. 9-03, Attach. B, § 1.3, 2003: Ord. 10-02, Attach. B, § 1.3, 2002).

"Repetitive loss" means flood-related damages sustained by a structure on two occasions during a ten-year period for which the costs of repairs at the time of each such flood event, on the average, equals or exceeds twenty-five percent of the market value of the structure before the damage occurred.

"Special flood risk zone" means the Zones A and A2 floodplain of the Skokomish River, Vance Creek and tributaries, as identified on Flood Insurance Rate Maps 530115 0175 D and 530115 0180 D, both dated December 8, 1998, or as amended.

"Start of construction" includes substantial improvement, 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 days of the permit date. The actual start means either 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 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 the 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, as well as a manufactured home.

"Substantial damage" means damage of any origin sustained by a structure whereby cost of restoring the structure to its before damaged condition would equal or exceed fifty percent of the market value of the structure before the damage occurred.

"Substantial improvement" means any repair, reconstruction, or improvement of a structure, taking place during a ten-year period, in which the cumulative cost equals or exceeds fifty percent of the market value of the structure either:

(1) Before the improvement or repair is started, or

(2) If the structure has been damaged and is being restored, before the damage occurred. For the purpose 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.

This term includes structures which have incurred "repetitive loss" or "substantial damage" regardless of the actual amount of repair work performed.

The term does not, however, include either:

(1) Any project for improvement of a structure to comply with existing state or local health, sanitary, or safety code specifications which have been identified by the local code enforcement official, and which was in existence prior to the damage event or improvement, and which are solely necessary to assure safe living conditions, or

(2) 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.

"Wetlands" refer to the definition in the Mason County resource ordinance.

The areas of special flood hazard identified by the Federal Insurance Administration in a scientific and engineering report entitled "The Flood Insurance Study for the Mason County" dated May 17, 1988, and revised December 8, 1998, with accompanying Flood Insurance Maps, and any subsequent amendments thereto, is adopted by reference and declared to be a part of this chapter. The Flood Insurance Study is on file at the Mason County department of community development, Building I, 411 N. 5th St., Shelton, Washington.

(Ord. 87-08 Attach. A (part), § 3.2, 2008: Ord. 81-07, Attach. A, § 3.2, 2007: Ord. 9-03, Attach. B8, § 3.2, 2003: Ord. 10-02, Attach. B, § 3.2, 2002: Ord. 16-00, Attach. B, § 3.2, 2000: Ord. 59-91, § 3.2, 1991).

14.22.070 Penalties for noncompliance.

No structure or land shall hereafter be constructed, located, extended, converted, or altered without full compliance with the terms of this chapter and other applicable regulations. Violation of the provisions of this chapter by failure to comply with any of its requirements (including violations of conditions and safeguards established in connection with conditions) shall constitute a misdemeanor. Any person who violates this chapter or fails to comply with any of its requirements shall upon conviction thereof be fined not more than one thousand dollars imprisoned for not more than sixty days, or both, for each violation, and in addition shall pay all costs and expenses involved in the case. Nothing herein contained shall prevent Mason County from taking such other lawful action as is necessary to prevent or remedy any violation. The Mason County Development Code Chapter 15.13 provides for enforcement of violations to permits.

(Ord. 87-08 Attach. A (part), § 3.3, 2008: Ord. 81-07, Attach. A, § 3.3, 2007: Ord. 9-03, Attach. B8, § 3.3, 2003: Ord. 10-02, Attach. B, § 3.3, 2002: Ord. 16-00, Attach. B, § 3.3, 2000: Ord. 59-91, § 3.3, 1991).

14.22.080 Abrogation and greater restrictions.

This chapter is not intended to repeal, abrogate, or impair any existing easements, covenants, or deed restrictions. However, where this chapter and another chapter, easement, covenant, or deed restriction conflict or overlap, whichever imposes the more stringent restrictions shall prevail.

(Ord. 87-08 Attach. A (part), § 3.4, 2008: Ord. 81-07, Attach. A, § 3.4, 2007: Ord. 9-03, Attach. B8, § 3.4, 2003: Ord. 10-02, Attach. B, § 3.4, 2002: Ord. 16-00, Attach. B, § 3.4, 2000: Ord. 59-91, § 3.4, 1991).

14.22.090 Interpretation.

In the interpretation and application of this chapter, all provisions shall be:

(1) Considered as a minimum requirements;

(2) Deemed neither to limit nor repeal any other powers granted under state statutes.

14.22.100 Warning and disclaimer of liability.

The degree of flood protection required by this chapter is considered reasonable for regulatory purposes and is based on scientific and engineering considerations. Larger floods can and will occur on rare occasions. Flood heights may be increased by man-made or natural causes. This chapter does not imply that land outside the areas of special flood hazards or uses permitted within such areas will be free from flooding or flood damages. This chapter shall not create liability on the part of Mason County, any officer or employee thereof, or the Federal Insurance Administration, for any flood damages that result from reliance on this chapter or any administrative decision lawfully made hereunder.

(Ord. 87-08 Attach. A (part), § 3.6, 2008: Ord. 81-07, Attach. A, § 3.6, 2007: Ord. 9-03, Attach. B8, § 3.6, 2003: Ord. 10-02, Attach. B, § 3.6, 2002: Ord. 16-00, Attach. B, § 3.6, 2000: Ord. 59-91, § 3.6, 1991).

Article IV.
Administration

14.22.110 Establishment of development permit.

(a) Development Permit Required. A development permit shall be obtained before construction or development begins within any area of special flood hazard established in Section 14.22.060. The permit shall be for all structures including manufactured homes, and for all development including fill and other activities, as set forth in the "Definitions." If no other county permit is required, a development permit shall be required.

(b) Application for Development Permit. Application for a development permit shall be made on forms furnished by Mason County, which can be obtained from the Mason County department of community development. Application materials may include but not be limited to plans in triplicate drawn to scale showing the nature, location, dimensions, and elevations of the area in question and 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 new or substantially improved structures;

(2) Elevation in relation to mean sea level to which any structure has been floodproofed;

(3) Certification by a registered professional engineer or architect that the floodproofing methods for any nonresidential structure meet the floodproofing criteria in Section 14.22.160(2); and

(4) Description of the extent to which a watercourse will be altered or relocated as a result of proposed development.

(Ord. 87-08 Attach. A (part), § 4.1, 2008: Ord. 81-07, Attach. A, § 4.1, 2007: Ord. 9-03, Attach. B8, § 4.1, 2003: Ord. 10-02, Attach. B, § 4.1, 2002: Ord. 16-00, Attach. B, § 4.1, 2000: Ord. 59-91, § 4.1, 1991).

14.22.120 Designation of the administrator.

The administrator is appointed to administer and implement this chapter by granting or denying development permit applications in accordance with ordinance provisions. The administrator may consult with other departments and/or agencies with expertise to assist in permitting decisions.

(Ord. 87-08 Attach. A (part), § 4.2, 2008: Ord. 81-07, Attach. A, § 4.2, 2007: Ord. 9-03, Attach. B8, § 4.2, 2003: Ord. 10-02, Attach. B, § 4.2, 2002: Ord. 16-00, Attach. B, § 4.2, 2000: Ord. 59-91, § 4.2, 1991).

14.22.130 Duties and responsibilities of the administrator.

Duties of the administrator shall include, but not be limited to:

(1) Permit Review.

(A) Review all development permits to determine that the permit requirements of this chapter have been satisfied.

(B) 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.

(C) Review all development permits to determine if the proposed development is located in the floodway, or special flood risk zone as defined in Section 14.22.040. If located in the floodway, assure that the provisions of Section 14.22.180 are met. If located in a special flood risk zone, assure that the provisions of Section 14.22.190 are met.

(D) Review applications for emergency permits. An emergency shall be defined as set forth in WAC 173.27.040 (2)d, which includes the following language:

"Emergency construction necessary to protect property from damage by the elements. An "emergency" is an unanticipated and imminent threat to public health, safety, or the environment which requires immediate action within a time too short to allow full compliance with this Ordinance. Emergency construction does not include development of new permanent protective structures where none previously existed. Where new protective structures are deemed by the administrator to be an appropriate means to address the emergency situation, upon abatement of the emergency situation, the new structure shall be removed or any permit which would have been required, absent an emergency, pursuant to Chapter 90.58 RCW of these regulations or the local master program, shall be obtained."

(2) Use of Other Base Flood Data. When base flood elevation data has not been provided in accordance with Section 14.22.060, Basis for establishing the areas of special flood hazard, the 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 Sections 14.22.160, Specific standards, 14.22.180 Floodways, and 14.22.190 Special flood risk zone.

(3) Information to be Obtained and Maintained.

(A) Where base flood elevation data is provided through the Flood Insurance Study or required as in subsection (2) of this section, obtain and record the actual (as-built) elevation (in relation to mean sea level) of the lowest floor, including basement, of all new or substantially improved structures, and whether or not the structure contains a basement.

(B) For all new or substantially improved floodproofed structures:

(i) Verify and record the actual elevation (in relation to mean sea level) to which the structure was flood-proofed, and

(ii) Maintain the floodproofing certifications required in Section 14.22.110(b)(3).

(c) Maintain for public inspection all records pertaining to these ordinance provisions.

(4) Alteration of Watercourses.

(A) Notify adjacent communities and property owners, and the Washington State Department of Ecology and Washington State Department of Fish and Wildlife, prior to any alteration or relocation of a watercourse, and submit evidence of such notification to the Federal Insurance Administration.

(B) Require that maintenance is provided within the altered or relocated portion of said watercourse so that the flood carrying capacity is not diminished.

(5) Interpretation of FIRM Boundaries. Make interpretations where needed, as to exact location of the boundaries of the areas of special flood hazards (for example, where there appears to be conflict between a mapped boundary and actual field conditions). The person contesting the location of the boundary shall be given a reasonable opportunity to appeal the interpretation as provided by Section 14.22.140. However, if it is clear from examining the FIRM map that the subject property or development is located within the area of special flood hazard, the person contesting the location of the boundary shall apply to FEMA for a map amendment.

(Ord. 87-08 Attach. A (part), § 4.3, 2008: Ord. 81-07, Attach. A, § 4.3, 2007: Ord. 9-03, Attach. B8, § 4.3, 2003: Ord. 10-02, Attach. B, § 4.3, 2002: Ord. 16-00, Attach. B, § 4.3, 2000: Ord. 59-91, § 4.3, 1991).

14.22.140 Variance procedure and reasonable use exception.

(a) Appeal Board.

(1) The hearing examiner shall act as the board of appeals to hear and decide appeals and requests for variances from the requirements of this chapter, as provided by Title 15, Mason County Code.

(2) The board of appeals shall hear and decide appeals when it is alleged there is an error in any requirement, decision, or determination made by the administrator in the enforcement or administration of this chapter.

(3) Those aggrieved by the decision of the board of appeals, or any taxpayer, may appeal such decision to the Superior Court, as provided in Chapter 36.70 RCW.

(4) In passing upon such applications, the board of appeals 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;

(C) 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

(K) The costs of providing governmental services during and after flood conditions, including maintenance and repair of public utilities and facilities such as sewer, gas, electrical, water systems, streets and bridges.

(L) The potential impacts to fish and riparian habitat, as provided for within the fish and wildlife habitat conservation areas chapter of the resource ordinance.

(5) Upon consideration of the factors of subsection (a)(4) and the purposes of this chapter, the board of appeals may attach such conditions to the granting of variances as it deems necessary to further the purposes of this chapter.

(6) The administrator shall maintain the records of all appeal actions and report any variances to the Federal Insurance Administration upon request.

(b) Conditions of Variances.

(1) Generally, the only condition under which a variance from the elevation standard may be issued is for new construction and substantial improvements to be erected on a lot of one-half acre or less in size contiguous to and surrounded by lots with existing structures constructed below the base flood level, providing subsections (a)(4)(A) through (a)(4)(L) of this section have been fully considered. As the lot size increases, the technical justification required for issuing the variance increases.

(2) 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, without regard to the procedures set forth in this section.

(3) Variances shall not be issued within a designated floodway if any increase in flood levels during the base flood discharge would result.

(4) Variances shall only be issued upon a determination that the variance is the minimum necessary, considering the flood hazard, to afford relief.

(5) Variances shall only be issued upon:

(A) A showing of good and sufficient cause;

(B) A determination that failure to grant the variance would result in exceptional hardship to the applicant;

(C) 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 subsection (a)(4) of this section, or conflict with existing local laws or ordinances.

(6) 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, 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. Variances shall not be granted for residential or commercial construction in floodways designated by this chapter.

(7) Variances may be issued for nonresidential buildings in very limited circumstances to allow a lesser degree of flood proofing than watertight or dry-flood proofing, where it can be determined that such action will have low damage potential, complies with all other variance criteria except subsection (b)(1) of this section, and otherwise complies with Sections 14.22.150(1) and (2) of the general standards.

(8) 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.

(c) Reasonable Use Exception. Nothing in this chapter is intended to preclude all reasonable use of property. An applicant for a development proposal may file a request for a reasonable use exception which shall be considered by hearing examiner at a public hearing. The reasonable use exception is not intended to allow residential development in designated floodways.

(1) The hearing examiner may allow a use which is consistent with the general purposes of this chapter and the public interest provided it meets the following criteria:

(A) There is no other reasonable use or feasible alternative to the proposed development with less impact on flood levels, critical areas, or resource lands; and

(B) The proposed development does not pose a threat to the public health, safety or welfare on or off the site; and

(C) The inability of the applicant to derive reasonable use of the property is not the result of actions by the applicant in creating the undevelopable condition after the effective date of the ordinance codified in this chapter; and

(D) The proposal is the minimum necessary while still allowing reasonable use of the site.

(2) Applications shall include the following information:

(A) A description of the areas of the site which are critical areas and/or resource lands or within setbacks required under the Mason County resource ordinance;

(B) A description of the amount of the site which is within setbacks required by other county standards;

(C) A description of the proposed development, including a site plan and topographic contour information adequate to determine flood depths on the site and property;

(D) An analysis of the impact that the amount of development would have on the resource lands or critical areas;

(E) An analysis of whether any other reasonable use with less impact on the resource lands or critical areas is possible;

(F) A design of the proposal so that the amount of development proposed as reasonable use will have the least impact practicable on the resource lands and/or critical areas;

(G) An economic analysis establishing the respective present values of development allowed under these regulations without the reasonable use exception and with the requested exception or alternative exceptions;

(H) Other information as the administrator determines is reasonably necessary to evaluate the issue of reasonable use as it relates to the proposed development.

(3) Application Process and Review.

(A) The application shall be submitted to the administrator along with fees established by ordinance for reasonable use exceptions.

(B) Public notice shall be as provided in Title 15 for public hearings.

(C) The administrator shall prepare an analysis of the merits of the request and make recommendations to the board of commissioners.

(4) Except when application from this chapter would deny all reasonable use of a site, an applicant who seeks an exception from the regulations of this chapter shall pursue a variance as provided in this section.

(5) The administrator shall maintain the records of all reasonable use exceptions granted and report them to the Federal Insurance Administration upon request.

(Ord. 87-08 Attach. A (part), § 4.4, 2008: Ord. 81-07, Attach. A, § 4.4, 2007: Ord. 9-03, Attach. B8, § 4.4, 2003: Ord. 10-02, Attach. B, § 4.4, 2002: Ord. 16-00, Attach. B, § 4.4, 2000: Ord. 59-91, § 4.4, 1991).

Article V.
Provisions for Flood Hazard Reduction

14.22.150 General standards.

In all areas of special flood hazards as shown on the Flood Insurance Rate Maps (FIRM) and as defined in Section 14.22.040, the following standards are required:

(1) Anchoring.

(A) All new construction and substantial improvements shall be anchored to prevent flotation, collapse, or lateral movement of the structure.

(B) All manufactured homes must likewise be anchored to prevent flotation, collapse, or lateral movement, and shall be installed using methods and practices that minimize flood damage. Anchoring methods may include, but are not limited to, use of over-the-top or frame ties to ground anchors. (Reference "FEMA 85– Manufactured Home Installation in Flood Hazard Areas" guidebook for additional techniques.)

(2) Construction Materials and Methods.

(A) All new construction and substantial improvements shall be constructed with materials and utility equipment resistant to flood damage.

(B) All new construction and substantial improvements shall be constructed using methods and practices that minimize flood damage.

(C) Electrical, heating, ventilation, plumbing, and air conditioning equipment and other service facilities shall be designed and/or otherwise elevated or located so as to prevent water from entering or accumulating within the components during conditions of flooding.

(3) Utilities.

(A) All new and replacement water supply systems shall be designed to minimize or eliminate infiltration of floodwaters into the system.

(B) The proposed water well shall be located on high ground that is not in the floodway. It shall be protected from a one hundred-year flood and from any surface or subsurface drainage capable of impairing the quality of the ground water supply (WAC 173-160-171).

(C) New and replacement sanitary sewage systems shall be designed to minimize or eliminate infiltration of floodwaters into the systems and discharge from the systems into floodwaters.

(D) On-site waste disposal systems shall be located to avoid impairment to them or contamination from them during flooding.

(4) Subdivision Proposals.

(A) All subdivision proposals shall be consistent with the need to minimize flood damage.

(B) All subdivision proposals shall have public utilities and facilities such as sewer, gas, electrical, and water systems located and constructed to minimize flood damage.

(C) All subdivision proposals shall have adequate drainage provided to reduce exposure to flood damage.

(D) Where base flood elevation data has not been provided or is not available from another authoritative source, it shall be generated for subdivision proposals and other proposed developments which contain at least fifty lots or five acres (whichever is less).

(E) Proposals for subdivisions or boundary line adjustments shall not result in any lot which is nonconforming to the provisions of this chapter.

(F) Subdivisions located entirely within a floodplain shall not be allowed increased density through a performance or clustered subdivision as described in Title 16. A performance subdivision may be used for parcels located partially within a floodplain provided all allowed building areas are located outside the floodplain, and all other regulatory provisions are met. When feasible, lots shall be designed to locate building sites outside the floodplain.

(G) No parcel shall be created that would require a reasonable use exception or variance before new residential or commercial construction would be allowed.

(5) Review of Building Permits. Where elevation data is not available either through the Flood Insurance Study or from another authoritative source (Section 14.22.130(2)), 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 judgement and includes use of historical data, high water marks, photographs of past flooding, etc., where available. Failure to elevate at least two feet above the highest adjacent grade in these zones may result in higher insurance rates.

(Ord. 87-08 Attach. A (part), § 5.1, 2008: Ord. 81-07, Attach. A, § 5.1, 2007: Ord. 9-03, Attach. B8, § 5.1, 2003: Ord. 10-02, Attach. B, § 5.1, 2002: Ord. 16-00, Attach. B, § 5.1, 2000: Ord. 59-91, § 5.1, 1991).

14.22.160 Specific standards.

In all areas of special flood hazards and special flood risk zones where base flood elevation data has been provided as set forth in Section 14.22.060, Basis for establishing the areas of special flood hazard or Section 14.22.130(b), Use of other base flood data, the following provisions are required:

(1) Residential Construction.

(A) New construction and substantial improvement of any residential structure shall have the lowest floor, including basement, elevated one foot or more above base flood elevation.

(B) Fully enclosed areas below the lowest floor that are subject to flooding are prohibited, or shall be designed to automatically equalize hydrostatic flood forces on exterior walls by allowing for the entry and exit of floodwaters. Designs for meeting this requirement must either be certified by a registered professional engineer or architect or must meet or exceed the following minimum criteria:

(i) A minimum of two openings having a total net area of not less than one square inch for every square foot of enclosed area subject to flooding shall be provided;

(ii) The bottom of all openings shall be no higher than one foot above grade;

(iii) Openings may be equipped with screens, louvers, or other coverings or devices provided that they permit the automatic entry an exit of floodwaters.

(C) If crawlspaces are used and have enclosed areas or floors below the base flood elevation, then the following requirements apply:

(i) The building must be designed and adequately anchored to resist flotation, collapse, and lateral movement of the structure resulting from hydrodynamic and hydrostatic loads, including the effects of buoyancy. Hydrostatic loads and the effects of buoyancy can usually be addressed though the required openings discussed in the next bullet. Because of hydrodynamic loads, crawlspace construction is not recommended in areas with flood velocities greater than five feet per second unless the design is reviewed by a qualified design professional, such as a registered architect or professional engineer. Other types of foundations are recommended for these areas.

(ii) The crawlspace is an enclosed area below the BFE and, as such, must have openings that equalize hydrostatic pressures by allowing for the automatic entry and exit of floodwaters. The bottom of each flood vent opening can be no more than one foot above the lowest adjacent exterior grade. For guidance on flood openings, see FEMA Technical Bulletin 1-93, Openings in Foundation Walls.

(iii) Crawlspace construction is not permitted in V zones. Open pile or column foundations that withstand storm surge and wave forces are required in V zones.

(iv) Portions of the building below the BFE must be constructed with materials resistant to flood damage. This includes not only the foundation walls of the crawlspace used to elevate the building, but also any joists, insulation, or other materials that extend below the BFE. The recommended construction practice is to elevate the bottom of joists and all insulation above BFE. Insulation is not a flood-resistant material. When insulation becomes saturated with floodwater, the additional weight often pulls it away from the joists and flooring. Ductwork or other utility systems located below the insulation may also pull away from their supports. See the section Flood-Resistant Materials, on page 8 of FEMA Technical Bulletin 1-93. For more detailed guidance on flood-resistant materials see FEMA Technical Bulletin 2-93, Flood-Resistant Materials Requirements.

(v) Any building utility systems within the crawlspace must be elevated above BFE or designed so that floodwaters cannot enter or accumulate within the system components during flood conditions. Ductwork, in particular, must either be placed above the BFE or sealed from floodwaters. For further guidance on the placement of building utility systems in crawlspaces, see FEMA 348, Protecting Building Utilities from Flood Damage.

(vi) The interior grade of a crawlspace below the BFE must not be more than two feet below the lowest adjacent exterior grade (LAG), shown as D in Figure 1.

(vii) The height of the below-grade crawlspace, measured from the interior grade of the crawlspace to the top of the crawlspace foundation wall must not exceed four feet (shown as L in Figure 1) at any point. The height limitation is the maximum allowable unsupported wall height according to the engineering analyses and building code requirements for flood hazard areas (see the section Guidance for Pre-Engineered Crawlspaces, on page 7 of FEMA Technical Bulletin 1-93). This limitation will also prevent these crawlspaces from being converted into habitable spaces.

(viii) There must be an adequate drainage system that removes floodwaters from the interior area of the crawlspace. The enclosed area should be drained within a reasonable time after a flood event. The type of drainage system will vary because of the site gradient and other drainage

characteristics, such as soil types. Possible options include natural drainage through porous, well-drained soils and drainage systems such as perforated pipes, drainage tiles, or gravel or crushed stone drainage by gravity or mechanical means.

(ix) The velocity of floodwaters at the site should not exceed five feet per second for any crawlspace. For velocities in excess of five feet per second, other foundation types should be used.

(x) Below-grade crawlspace construction in accordance with the requirements listed above will not be considered basements.

(2) Nonresidential Construction. New construction and substantial improvement of any commercial, industrial or other nonresidential structure, except those defined as an accessory structure, shall either have the lowest floor, including basement, elevated one foot or more above the level of the base flood elevation; or, together with attendant utility and sanitary facilities, shall:

(A) Be flood proofed so that below one foot 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 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 subsection 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 Section 14.22.130(3)(B);

(D) Nonresidential structures that are elevated, not flood proofed, must meet the same standards for space below the lowest floor as described in subsection (1)(B) of this section;

(e) Applicants floodproofing 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 one foot above the base flood level will be rated as at the base flood level).

(3) Accessory Structures. Construction or substantial improvement of accessory structures, as defined in Section 14.22.040, shall either have the lowest floor elevated one foot or more above the level of the base flood elevation; or must meet the following criteria:

(A) A minimum of two openings having a total net area of not less than one square inch for every square foot of enclosed area subject to flooding shall be provided.

(B) The bottom of all openings shall be no higher than one foot above grade.

(C) Openings may be equipped with screens, louvers, or other coverings provided they may permit the automatic entry and exit of floodwaters.

(D) Structures shall not be designed for human habitation.

(E) Structures shall be firmly anchored to prevent flotation which may result in damage to other structures.

(F) Service facilities such as electrical and heating equipment shall be elevated or flood proofed.

(4) Critical Facility. Construction of new critical facilities shall be, to the extent possible, located outside the limits of the base floodplain. Construction of new critical facilities shall be permissible within the base floodplain if no feasible alternative site is available. Critical facilities constructed within the base floodplain shall have the lowest floor elevated to three feet or more above the level of the base flood elevation at the site. Flood proofing and sealing measures must be taken to ensure that toxic substances will not be displaced by or released into floodwaters.

Sections:

14.46.010 Purpose.

14.46.020 Boundaries.

14.46.030 Utility responsibilities.

14.46.031 Organization of the utility.

14.46.040 Financial management.

14.46.010 Purpose.

A storm and surface water utility is created for Mason County to develop and implement strategies and actions to reduce the frequency and severity of flooding so hazardous situations are eliminated; water quality improvement in all local streams, water bodies, Puget Sound and Hood Canal are achieved; the loss of important aquatic habitats is minimized. The goal of the utility will be to mediate conflicts between the pressures created by development and the need to conserve Mason County's natural environment.

(Ord. 80-08 Attach. A (part), 2008).

14.46.020 Boundaries.

The boundaries of the utility will change over time. Initially the boundaries of the utility will be the Belfair and Allyn urban growth areas as illustrated on Map No. 1. Future expansion of boundaries will be based on the following schedule unless development impacts, new research, or declining water quality and habitat loss indicates a more aggressive need to include the areas in the utility boundaries earlier.

* Based on development impacts and water quality

** Designated forest lands will not be included in any utility boundary

(1) Within the Belfair and Allyn urban growth area as defined on Map No. 1, applicable sections of Chapter 14.48 of this regulation will govern the development of land. This will include provisions of the 2005 Department of Ecology Drainage Manual or any version that might be developed in the future. This will include the use of low impact development techniques.

(2) Outside the Belfair and Allyn urban growth area as defined on Map No. 1, applicable sections of Chapter 14.48 will govern the development of land until they might be added to the boundaries of the utility. When new utility territory is added subsection (1) of this section.

(3) Regardless of location, any land employing the master plan development process will be required to meet the requirements of subsection (1) of this section and the required sections of Chapter 14.48.

(Ord. 80-08 Attach. A (part), 2008).

14.46.030 Utility responsibilities.

The utility will have three basic responsibilities:

(1) Flooding management;

(2) Water quality improvement;

(3) Protecting aquatic habitat.

(Ord. 80-08 Attach. A (part), 2008).

14.46.031 Organization of the utility.

The utility will be organized to perform the following functions:
Responsible Department
Environmental planning and policy developmentUtilities and waste management and environmental health

(Ord. 80-08 Attach. A (part), 2008).

14.46.040 Financial management.

There are no annual stormwater fees associated with the creation of the utility at this time. Assessments or fees may become necessary to support the utility and its functions. Any fee system may be based on impervious surfaces, including all hard surfaces on a property including roof areas. Designated forest, agricultural lands, and open space lands will be exempt from payment of any assessment or fees. Properties greater than twenty acres in size with structures and impervious surfaces will pay a reduced rate. Such rate will be fifty percent of the established rate.

Public and private roads constructed of impervious surfacing materials or portion thereof so constructed may be required to pay a fee not to exceed one hundred thousand dollars per year based on maintenance and monitoring needs for retrofit projects. A priority list of projects will be developed before any fee or assessment is collected. These projects can be ones that prevent flooding or manage water quality or preserve aquatic habitat. The first choice for control of any kind should be natural over man-made or built structures.

Article I.
Findings of Fact, Need and Purpose

14.48.010 Findings of fact.

The board of Mason County commissioners of Mason County finds that:

(1) This chapter is divided into two parts. The first part defines requirements within the area covered by the storm and surface water utility. Development actions in these areas will be governed by the 2005 Edition of the Department of Ecology's Stormwater Manual. The Belfair and Allyn UGA's are included in the storm and surface water utility, which was created on June 17, 2008. Other areas of the county may be added as described in Chapter 14.46, to the storm and surface water utility. The second part of the ordinance will regulate development in areas outside the storm and surface water utility including any areas added in the future. Areas outside of the storm and surface water utility are governed by provisions of the 1992 Department of Ecology Stormwater Manual.

(2) The 1994 Puget Sound Water Quality Management Plan (as amended) requires all counties and cities within the Puget Sound drainage basin to adopt ordinances to control runoff from new development and redevelopment by January 1, 1995. The plan also directs local governments to adopt stormwater programs, which include minimum requirements for new development and redevelopment set by the plan and in guidance developed by Ecology.

(3) Stormwater is a problem associated with land utilization and development and common occurrence of potential pollutants such as pesticides, fertilizers, petroleum products, animal wastes and numerous others.

Land utilization and development is also known to increase both the volume and duration of peak flows. The resulting erosion, scouring, and deposition of sediment affect the ecological balance in the stream.

Sedimentation and stormwater pollution cause diversity of species to decrease and allows more tolerant (and usually less desirable) species to remain.

Stormwater pollution can cause or contribute to closures of shellfish beds and swimming beaches and other restrictions on public use of the waters within Mason County.

(4) An expanding population and increased development of land have led to:

(A) Water quality degradation through discharge of nutrients, metals, oil and grease, toxic materials, and other detrimental substances including, without limitation, insect and weed control compounds;

(B) Drainage and storm and surface water runoff problems within Mason County; and

(C) Safety hazards to both lives and property posed by uncontrolled water runoff on streets and highways.

(5) Continuation of present stormwater practices, to the extent that they exist, will lead to water quality degradation, erosion, property damage, and endanger the health and safety of the inhabitants of the county.

(6) In the future such problems and dangers will be reduced or avoided if existing properties and future developers, both private and public, provide for stormwater quality and quantity controls.

(7) Stormwater quality and quantity controls can be achieved when land is developed or redeveloped by implementing appropriate best management practices (BMPs).

(8) Best management practices can be expected to perform as intended only when properly designed, constructed and maintained.

(Ord. 81-08 (part), 2008).

14.48.020 Need.

The county finds that this chapter is necessary in order to:

(1) Satisfy the mandate of Ecology as identified in this section;

(2) Minimize or eliminate water quality degradation;

(3) Prevent erosion and sedimentation in creeks, streams, ponds, lakes and other water bodies;

(4) Protect property owners adjacent to existing and developing lands from the undesirable impacts of increased runoff rates;

(5) Preserve and enhance the suitability of waters for contact recreation, fishing, and other beneficial uses;

(6) Preserve and enhance the aesthetic quality of the water;

(7) Promote sound development policies, which respect and preserve county surface water and sediment;

(8) Ensure the safety of county roads and rights-of-way;

(9) Decrease stormwater-related damage to public and private property from existing and future runoff;

(10) To protect the health, safety and welfare of the inhabitants of the county.

(Ord. 81-08 (part), 2008).

14.48.030 Purpose.

The provisions of this chapter are intended to guide and advise all who conduct new development or redevelopment within Mason County. The provisions of this chapter establish the minimum level of compliance, which must be met to permit a property to be developed or redeveloped within Mason County.

It is the purpose of this chapter to:

(1) Minimize water quality degradation and sedimentation in streams, ponds, lakes, wetlands and other water bodies;

(2) Minimize the impact of increased runoff, erosion and sedimentation caused by land development and maintenance practices;

(3) Maintain and protect groundwater resources;

(4) Minimize adverse impacts of alterations on ground and surface water quantities, locations and flow patterns;

(5) Decrease potential landslide, flood and erosion damage to public and private property;

(6) Promote site planning and construction practices that are consistent with natural topographical, vegetational and hydrological conditions;

(7) Maintain and protect the county stormwater infrastructure and those downstream;

(8) Provide a means of regulating clearing and grading of private and public land while minimizing water quality impacts; and

(9) Provide guidance on development and construction procedures, which will encourage the preservation of existing natural vegetation to the maximum extent practicable.

(B) Erosion and Sediment Control Requirement #2: Delineate Clearing and Easement Limits. In the field, mark clearing limits and/or any easements, setbacks, sensitive/critical areas and their buffers, trees, and drainage courses.

(C) Erosion and Sediment Control Requirement #3: Protection of Adjacent Properties. Properties adjacent to the project site shall be protected from damage by sediment deposition.

(D) Erosion and Sediment Control Requirement #4: Timing and Stabilization of Sediment Trapping Measures. Sediment ponds and traps, perimeter dikes, sediment barriers, and other BMPs intended to trap sediment on-site shall be constructed as a first step in grading. These BMPs shall be functional before land disturbing activities take place. Earthen structures such as dams, dikes, and diversions shall be seeded and mulched according to the timing indicated in erosion and sediment control requirement #1.

(E) Erosion and Sediment Control Requirement #5: Cut and Fill Slopes. Cut and fill slopes shall be designed and constructed in a manner that will minimize erosion. In addition, slopes shall be stabilized in accordance with erosion and sediment control requirement #1.

Supplemental Guidelines: Consideration should be given to the length and steepness of the slope, the soil type, upslope drainage area, ground water conditions, and other applicable factors. Slopes which are found to be eroding excessively within two years of construction must be provided with additional slope stabilizing measures until the problem is corrected.

(i) Roughened soil surfaces are preferred to smooth surfaces on slopes (see BMP E2.35 in Chapter II-5).

(ii) Interceptors (see BMP E2.55 in Chapter II-5) should be constructed at the top of long steep slopes, which have significant drainage areas above the slope. Diversions or terraces may also be used to reduce slope length.

(iii) Concentrated stormwater should not be allowed to flow down cut or fill slopes unless contained within an adequate temporary or permanent channel, or pipe slope drain (see BMP E2.25 in Chapter II-5).

(iv) Wherever a slope face crosses a water seepage plane which endangers the stability of the slope, adequate drainage or other protection should be provided (BMPs E2.30 and E2.75 in Chapter II-5).

(F) Erosion and Sediment Control Requirement #6: Controlling Off-site Erosion. Properties and waterways downstream from development sites shall be protected from damage by erosion due to increases in the volume, velocity, or peak flow rate of stormwater runoff from the project site.

(G) Erosion and Sediment Control Requirement #7: Stabilization of Temporary Conveyance Channels and Outlets. All temporary on-site conveyance channels shall be designed, constructed and stabilized to prevent erosion from the expected velocity of the peak flow from a two-year, twenty-four hour frequency storm for the developed condition. Stabilization adequate to prevent erosion of outlets, adjacent streambanks, slopes and downstream reaches shall be provided at the outlets of all conveyance systems.

(H) Erosion and Sediment Control Requirement #8: Storm Drain Inlet Protection. All storm drain inlets made operable during construction shall be protected so that stormwater runoff shall not be discharged offsite or be introduced into any fill area without first being filtered or otherwise treated to remove sediment.

(I) Erosion and Sediment Control Requirement #9: Underground Utility Construction. The construction of underground utility lines shall be subject to the following criteria:

(i) No more than five hundred feet of trench shall be opened at one time, unless provisions are made to protect against adverse stormwater impacts.

(ii) Where consistent with safety and space considerations, excavated material shall be placed on the uphill side of trenches.

(iii) Trench dewatering devices shall discharge into a sediment trap or sediment pond.

(J) Erosion and Sediment Control Requirement #10: Construction Access Routes. Construction vehicle access shall be, whenever possible, limited to one route. Access points shall be stabilized to minimize the tracking of sediment onto public roads.

Wherever construction vehicle access routes intersect paved roads, provisions must be made to minimize the transport of sediment (mud) onto the paved road. If sediment is transported onto a road surface creating a hazard, the roads shall be cleaned immediately, and thoroughly cleaned at the end of each day. Sediment shall be removed from roads by shoveling or sweeping and be transported to a controlled sediment disposal area. Street washing shall be allowed only after sediment is removed in this manner.

(K) Erosion and Sediment Control Requirement #11: Removal of Temporary BMPs. All temporary erosion and sediment control BMPs shall be removed within thirty days after final site stabilization is achieved or after the temporary BMPs are no longer needed. Trapped sediment shall be removed or stabilized on site. Disturbed soil areas resulting from removal shall be permanently stabilized.

(L) Erosion and Sediment Control Requirement #12: Dewatering Construction Sites. Trench dewatering devices shall be discharged in a manner that will not adversely affect flowing streams, drainage systems, or offsite property. Water discharged from dewatering pumps shall be routed through a sediment pond or trap unless it is clear.

(M) Erosion and Sediment Control Requirement #13: Control of Pollutants Other Than Sediment on Construction Sites. All pollutants other than sediment that occur on-site during construction shall be handled and disposed of in a manner that does not cause contamination of stormwater.

(N) Erosion and Sediment Control Requirement #14: Maintenance. All temporary and permanent erosion and sediment control BMPs shall be maintained and repaired as needed and in a timely manner to assure continued performance of there intended function. All maintenance and repair shall be conducted in accordance with an approved manual.

(O) Erosion and Sediment Control Requirement #15: Financial Liability. Performance bonding, or other appropriate instruments, may be required to ensure compliance with the approved erosion and sediment control plan.

(4) Minimum Requirement #2: Preservation of Natural Drainage Systems. Natural drainage patterns shall be maintained, and discharges from the site shall occur at the natural location to the maximum extent practicable.

(5) Minimum Requirement #3: Source Control of Pollution. Source control BMPs shall be applied to all projects to the maximum extent practicable. Source control BMPs shall be selected, designed, and maintained according to an approved manual. An adopted and implemented basin plan (minimum requirement #9) may be used to develop source control requirements that are tailored to a specific basin, however, in all circumstances, source control BMPs shall be required for all sites.

(6) Minimum Requirement #4: Runoff Treatment BMPS. All projects shall provide treatment of stormwater. Treatment BMPs shall be sized to capture and treat the water quality storm, defined as the six month, twenty-four hour storm. The first priority for treatment of stormwater shall be to infiltrate as much as possible of the water quality design storm into the ground. (Infiltration BMPs practices shall be in accordance with Chapter III-3 of the PSWQA Manual) Pretreatment of stormwater prior to infiltration into the ground may be required in cases where:

(A) The stormwater contains high concentrations of undesirable dissolved chemicals that can move through soil.

(B) The stormwater contains large amounts of sediment that might clog the infiltrative surfaces in the basin.

(C) The soils are extremely pervious and will not properly filter the stormwater as in the case for some gravelly (type one) soils.

Stormwater treatment BMPs shall not be built within a natural vegetated buffer, except for necessary conveyance systems as approved by the director.

An adopted and implemented basin plan (minimum requirement #9) may be used to develop runoff treatment requirements that are tailored to a specific basin.

The objectives of providing stormwater treatment BMPs are, for both surface and ground waters, to protect the quality and quantity, to allow attainment of the designated uses, and to meet state standards promulgated under Chapter 173 of the Washington Administrative Code.

(7) Minimum Requirement #5: Streambank Erosion Control. The requirement below applies only to situations where stormwater runoff is discharged directly or indirectly to a stream, and must be met in addition to meeting the requirements in Minimum Requirement #4, Runoff Treatment BMPs:

Stormwater discharges to streams shall control streambank erosion by limiting the peak rate of runoff from individual development sites to fifty percent of the existing condition two-year, twenty-four hour design storm while maintaining the existing condition peak runoff rate for the ten-year, twenty-four hour and one hundred-year, twenty-four hour design storms. As the first priority, streambank erosion control BMPs shall utilize infiltration to the fullest extent practicable, only if site conditions are appropriate and ground water quality is protected. Streambank erosion control BMPs shall be selected, designed, and maintained according to an approved manual.

Stormwater treatment BMPs shall not be built within a natural vegetated buffer, except for necessary conveyance systems as approved by the director, and maintained according to the 1992 manual.

An adopted and implemented basin plan (minimum requirement #9) may be used to develop streambank erosion control requirements that are tailored to a specific basin.

(8) Minimum Requirement #6: Wetlands. Stormwater discharges to wetlands shall maintain the wetland's natural hydroperiod and flows to the extent needed to preserve or enhance its existing functions and values. Prior to proposing discharge of higher volumes of stormwater to a wetland, alternative discharge, detention, and infiltration practices located in areas outside the wetland shall be evaluated and employed by the project engineer where feasible and practicable.

These requirements apply to existing natural wetlands and wetlands created as mitigation for loss of wetland acreage. Wetlands constructed and operated solely for use as stormwater treatment/storage areas are exempt from these and most other restrictions that apply to natural wetlands. Constructed wetlands may lose this exemption if not operated and maintained as stormwater areas for three or more years. Other local, state, or federal wetland protection requirements may also apply.

(9) Minimum Requirement #7: Water Quality Sensitive Areas. Where the Mason County commissioners or their designee determine that the minimum requirements do not provide adequate protection of water quality sensitive areas, either on-site or within the basin, more stringent controls shall be required to protect water quality. An adopted and implemented basin plan (minimum requirement #9) may be used to develop requirements for water quality sensitive areas that are tailored to a specific basin.

(10) Minimum Requirement #8: Off-site Analysis and Mitigation.

Downstream Analysis May Trigger Additional Requirements. The project engineer shall provide a detailed qualitative analysis of the flow path of the discharge from the project site to the receiving water. This requirement shall apply to all projects where a drainage and erosion control plan is prepared, including those proposing retention facilities. This analysis shall include flow routing, and provide existing pipe and channel sizes and estimated capacities. In addition, the project engineer shall discuss any known or expected downstream erosion, flooding, or water quality problems, including those that may be caused by interflow from the proposed retention facility. The director or designee shall have the discretion to specify the distance and level of detail to be provided by the project engineer. In making this determination, the director or designee shall consider such factors as the relative size of the new development, availability of other hydrologic work for the drainage area, and the extent to which stormwater generated on the project site is to be infiltrated.

Based upon this analysis, the project engineer may determine or the director or designee may require that a quantitative analysis of the conveyance system be performed both upstream and downstream of the project site. A quantitative analysis will not be required for most projects that propose to infiltrate most or all stormwater. This analysis shall determine conveyance system performance for the appropriate design event(s) both with and without the proposed development. The director or designee shall have the discretion to specify the distance and level of detail to be provided by the project engineer. The director or designee shall consider factors such as the relative size of the new development, availability of other hydrologic work for the drainage area, and the results of the qualitative analysis, in making this determination.

The quantitative downstream analysis will include modeling the hydraulics of the proposed project and all other sources of runoff tributary to the receiving water body for the appropriate design event. The project engineer shall include an analysis of the impact of the twenty-four hour, one hundred-year event (in addition to "Design Event" analysis) for each component of the system including pond spillway.

The director or designee may impose stricter discharge and/or detention standards if the discharge from the project, evaluated in the context of other existing conditions in the drainage area, is reasonably expected to result in any of the following:

(A) Flooding;

(B) Loss of aquatic habitat due either to high or low flows;

(C) Property damage;

(D) Water quality problems;

(E) Erosion;

(F) Or an unacceptable interruption of vital services.

If the project engineer (or director or designee) determines that greater treatment, infiltration and/or storage volumes, lower release rates, or downstream improvements are needed, he/she shall specify project design criteria or other means to relieve the downstream problems (providing that such solution will not violate minimum standards established in the 1992 manual). Other means might include increases in downstream flow capacity and/or offsite detention and infiltration facilities, plans and financing for which will be subject to the approval of the director or designee.

(11) Minimum Requirement #9: Basin Planning. Basin Plan Supersedes 1992 Manual. If a proposed project is located in a basin or sub basin for which the county has an adopted basin plan, stormwater requirements specifically identified in the basin plan shall take precedence over those provided in this chapter. However, all other elements detailed in this chapter shall continue to apply to such projects. Basin plans are required to be developed according to an approved manual.

(12) Minimum Requirement #10: Operation and Maintenance. An operation and maintenance schedule shall be provided for all proposed stormwater facilities and BMPs, and the party (or parties) responsible for maintenance and operation shall be identified. An operation and maintenance (O&M) Covenant will be required to cover all privately owned and maintained stormwater facilities approved by the director. O&M covenant forms are available at the Mason County public works office. A copy of the completed instrument, shall be recorded with the county auditors' office by the proponent, and a copy of the recorded instrument is required to be submitted to the public works department prior to final approval of the completed permanent stormwater facilities.

(13) Minimum Requirement #11: Financial Liability. Performance bonding, or other appropriate instruments shall be required for all projects to ensure compliance with these standards.

(14) Variances from These Standards. Variances from these standards may be allowed at the discretion of the director or designee provided that the proponent will substantially meet flow control and water quality goals established by or implicit in these standards. Compliance with ordinance requirements shall normally occur within the project area, but may be performed as offsite mitigation in certain situations. Examples of cases when variances may be approved includes, but are not limited to, the following:

(A) That the special conditions and circumstances exist which are peculiar to the land, such as size, shape, topography, or location, and that literal interpretation of these standards would deprive the property owner of rights commonly enjoyed by other properties similarly situated; or

(B) That the site is being remodeled and certain site investigations would be destructive to existing structures; or

(C) That remodels of existing projects which are either too small or so configured that in the director's or designee's opinion some requirements of the manual cannot practically be met; or

(D) That public works or private sector projects are in an existing road right-of-way, which is not of adequate size to install preferred BMPs and for which right-of-way cannot be expanded because of encroaching structures or setbacks for existing structures.

All requests for variances must be submitted in writing to the director or designee, and must clearly state the specific section(s) of the ordinance from which a variance is requested and why.

(15) Experimental BMPs. Experimental best management practices are defined as BMPs, which have not been tested and evaluated by the Department of Ecology in collaboration with local governments and technical experts. Some so-called experimental BMPs will likely be minor variations on an existing theme. In that case, Ecology would review and approve or disapprove the BMP in as timely a manner as possible. Where new designs are developed (examples of experimental BMPs may be found in Section I-2.17.2 of the PSWQA Manual), the review will be extended through the use of a standing committee of technical experts. These persons will review and comment on the practice, and Ecology will then determine whether or not these BMPs should be approved and/or added to the manual.

(A) Approval of Experimental BMPs. Approval to use an experimental BMP may be granted subject to initial approval by the Department of Ecology and the local government. If such experimental BMPs prove useful they may be incorporated into later editions of the manual following appraisal of the results and appropriate technical review conducted by Ecology in collaboration with local governments and other interested parties. Approval to use an experimental BMP will only be granted when a suitable contingency plan using approved BMPs has been provided by the applicant to be used in the event that the experimental BMP does not perform adequately.

In addition, several experimental BMPs have been included in the 1992 manual. People may wish to use these BMPs on a trial basis, subject to approval by the local government and provision of a contingency plan. In any event, use of experimental BMPs is encouraged whenever applied research is being undertaken so that more information is made available to facilitate judgement on their applicability and possible adoption as an approved BMP.
