City Council Agenda Item Report

Submitted by: Brenda FritsvoldSubmitting Department: City Manager's Office Meeting Date: August 29, 2017

Subject:Lodging Tax Awards for 2018

Presenter:Kevin Yamamoto, City Manager

Recommendation:Consideration of (1) the recommendations of the Lodging Tax Advisory Committee for applicant-initiated grant awardsin 2018, and (2) possible Council-initiated proposals for use of lodging tax funds in 2018.

Background:(Note: There is a statutory distinction between “applicant-initiated” funding requests, and proposals to use lodging taxfunds that are initiated by the City or Council, hereinafter referred to as “City-initiated" or "Council-initiated” expenditureproposals. Further explanation is set forth below.)

Applicant-Initiated Funding Requests

The Lodging Tax Advisory Committee (LTAC) met in early August to review and make recommendations for awardsof lodging tax funds to non-city applicants. The committee understood that per Council direction, their recommendationfor allocation awards should be $550,000 or under, with last year’s awards having been $558,000. The committee’srecommendations are attached—they total $603,000. (Note: The total amount available for allocation in 2017 was$1,225,633. The total amount available for allocation in 2018 is $1,260,245.)

The Council’s role is to now approve or reject each of the LTAC's recommended awards. In accordance with statelaw, the Council cannot increase or decrease awards, nor can it make an award to a recipient who is not on therecommended award list. Rather, the Council can choose only recipients from the list of candidates and recommendedamounts submitted by the LTAC. If the Council rejects a recommended award or awards, the Council can direct thatthe LTAC reconsider the recommended award or awards.

Council-Initiated Proposals

In the past, lodging tax funds have also been used to add pieces to the City's public art collection, fund equipmentupgrades for the Pavilion, and for book festivals in 2014, 2015 and 2017.

At this time, the Council should determine whether it wants to expend lodging tax funds for any City-initiated items, andif so, the amount of the proposed expenditures. Thereafter, pursuant to law, these proposed expenditures must bereferred to the LTAC for its review and comment--see attached for a more detailed explanation of the requiredprocess.

2

Potential City-initiated lodging tax allocations for 2018:• Arts Downtown, which curates the outdoor sculpture gallery, has suggested that the City expend up to $25,000in lodging tax funds for purchase of a sculpture in 2018. • The Puyallup Library seeks $40,000 for a book festival in 2018.• The Library seeks an additional $5,000 to help with the expense of hosting PuliCon, its annual mini comicconvention which draws up to 3,000 attendees. • No lodging tax funds are requested for the Pavilion in 2018, outside its usual debt service.

Council Direction:(1) Consider and decide whether to approve the LTAC's recommended allocations for 2018 as presented.(2) Consider and decide whether to forward any Council-initiated 2018 allocations to the LTAC for its review andcomment.

LODGING TAX PROPOSALS: CITY-INITIATED & APPLICANT-INITIATED

The process for approval of City-initiated (or Council) proposals to use LTAC revenue differs from the

process that governs applicant-initiated requests.

The statute that governs City-initiated proposals is RCW 67.28.1817, and it provides as follows:

Any municipality that proposes . . . a change in the use of [LTAC] revenue . . . shall submit the proposal to

the lodging tax advisory committee for review and comment.

The submission shall occur at least forty-five days before final action on or passage of the

proposal by the municipality.

The comments shall include an analysis of the extent to which the proposal will accommodate

activities for tourists or increase tourism, and the extent to which the proposal will affect the

long-term stability of the fund created under RCW 67.28.1815.

The advisory committee shall submit comments on the proposal in a timely manner.

Failure of the [LTAC] committee to submit comments before final action on or passage of the

proposal shall not prevent the municipality from acting on the proposal.

A municipality is not required to submit an amended proposal to [the LTAC] committee.

The statute that governs applicant-initiated proposals is RCW 67.28.1816, and it provides as follows:

In a municipality with a population of five thousand or more, applicants applying for use of [LTAC]

revenues . . . must submit their applications and estimates . . . to the local lodging tax advisory committee.

The local lodging tax advisory committee must select the candidates from amongst the

applicants applying for use of revenues . . . and provide a list of such candidates and

recommended amounts of funding to the municipality for final determination.

The municipality may choose only recipients from the list of candidates and recommended

amounts provided by the local lodging tax advisory committee.

The foregoing statutory language can be distilled as follows:

5

City-initiated:

1. City proposes change in the use of LTAC revenue.

2. Proposal submitted to LTAC committee for review and comment.

3. LTAC committee comments must include tourism and fund stability analysis.

4. Council acts on or passes the proposal.

Applicant-initiated:

1. Applicants for LTAC revenue submit their applications and tourism estimates to the LTAC

committee.

2. The LTAC committee selects candidates for LTAC revenue.

3. The LTAC committee provides a list of candidates and recommended amounts of funding to

the Council.

4. The Council may choose (or reject) only recipients from the list of candidates and

recommended amounts.

The major distinction between City-initiated proposals and applicant-initiated requests is as follows:

o City-initiated: The Council can disregard the LTAC committee comments and analysis and

pass or act on the City-initiated proposal.

o Applicant-initiated: The Council cannot disregard the LTAC committee recommendations;

the Council must either choose or reject candidates with recommended amounts on the

candidate list.

Submitted by: Tom UtterbackSubmitting Department: Development Services Meeting Date: August 29, 2017

Subject:Continued Policy Direction concerning homeless-serving land uses

Presenter:Tom Utterback

Recommendation:Receive an updated staff presentation on homeless-serving land uses and provide further policy direction

Background:On July 18, 2017, City Council heard an informational presentation regarding recent Planning Commission and staffwork on "homeless-serving land uses", which has been the focus of an ongoing City Council use moratorium. Thisproject has focused upon two land use types: daytime drop-in centers and overnight shelters. Staff presented possibleconceptual zoning standards, including use definitions, allowable zone districts, permit procedures, site standards andbuffers from certain sensitive uses. Buffer maps were presented depicting potential areas in which these uses could besited given the Planning Commission recommendation on allowable zone districts and sensitive use buffer options.

On July 18th, staff received general feedback from Councilmembers (CMs), which is outlined here:

- A majority of CM’s supported having some on-point zoning standards in place to address how/where thesehomeless-serving uses are permitted versus maintaining a case-by-case use determination approach. - CM’s clearly supported requiring a Conditional Use Permit for any proposed drop-in center or shelter use.- Multiple CM’s expressed concern about the downtown "CBD" zone districts being listed as potentially“allowable” for these homeless-serving uses, expressing that the downtown should not be an appropriate location. - There was general acceptance of the “sensitive uses” list as recommended, although some CM’s supportedadding the Riverwalk Trail to that list. - Several CM’s supported seeing a map depicting a single 1000’ buffer between these uses and all designatedsensitive uses (vs. the tiered 500'/250' or 1000’/500’ buffer maps, as presented on July 18th), although there werecomments about retaining some reasonable amount of area for potentially siting these homeless-serving uses. - There were CM comments supporting permanent residential units serving as transitional housing (e.g. HelpingHands House), wanting to ensure that social service model would not be adversely affected by any new zoningstandards.

On August 29th, City Council will re-visit this topic. Staff will present updated maps/information and request furtherCity Council input. This will include seeking specific direction on proposed zoning standards (e.g. definitions, sitestandards, zoning & sensitive uses), appropriate buffer setbacks and your overall vision for how best to accommodatethese uses.

Attachments to this study session packet for August 29th are: 8

o the Siting Analysis map presented to Council on July 18th (dated 7/17/17), showing eligible areas for locatingdaytime drop-in centers and overnight shelters given Planning Commission-recommended zones and a two-tiered 1000'(from schools, child care centers and senior care facilities)/500' (from parks, library and residentially-zoned parcels)buffer setbacks. (NOTE: this was originally presented as two maps, one each for drop-in centers and overnightshelters, but they have now been combined into a single map for brevity sake, as the affected parcels are the same foreach). o a new revised version of the 7/17/17 map (dated 8/23/17) which shows the Planning Commission-recommendedzone districts/sensitive uses, but with a uniform 1000' buffer for all sensitive uses, as supported by some CMs. o a new map (dated 8/23/17) which reflects City Council input from 7/18/17. This maintains the PlanningCommission-recommendation but uses a uniform 1000' buffer from all sensitive uses (now including the Riverwalk Trailcorridor) and also deletes the downtown zone districts (i.e. CBD, CBD-Core) from siting consideration.

On August 29th, staff will review these Siting Analysis map options, including corresponding Citywide acreages, andfurther outline the topic of appropriate buffers.

Council Direction:Receive an updated staff presentation on homeless-serving land uses and provide further policy direction.

CC DIRECTION FROM 7/18/17

Submitted by: Mark PalmerSubmitting Department: Capital Improvement Engineering Meeting Date: August 29, 2017

Subject:First reading of an ordinance amending portions of the Flood Damage Protection Code

Presenter:Mark Palmer

Recommendation:Approve first reading of the ordinance

Background:In March, Council adopted recently approved FEMA Flood Insurance Rate Maps and associated changes to flooddamage protection code to be in compliance with FEMA' s Flood Insurance Program. Because of unique circumstanceswith AO type flood plains and a requirement for compensatory storage, it would be virtually impossible to provide suchcompensatory storage and allow any development in these areas. The proposed amendments allow compensatorystorage to occur at elevations different than the flood elevations ONLY within AO zones and with supporting biologicalassessments confirming a "No-Take" standard. The City believes this will keep us in compliance with the FloodInsurance program while allowing reasonable use of properties within the AO zones of the City. The ordinance as proposed tonight for first reading is being sent concurrently to FEMA and DOE for review andcomment. After their 30-day review period has expired, staff will bring this ordinance back for second reading with anynecessary amendments based on their review. This will likely occur at the October 3, 2017 Council meeting.

Council Direction:Approve first reading of the ordinance

(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 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 assume responsibility for their actions. (Ord. 2888 § 1, 2007; Ord. 2112 § 2, 1987).

21.07.020 Methods of reducing flood losses.In order to accomplish its purposes, this chapter includes 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 alterations of natural floodplains, stream channels, and natural protective barriers, which help accommodate or channel floodwaters;

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

(5) Preventing or regulating the construction of flood barriers which will unnaturally divert floodwaters or may increase flood hazards in other areas. (Ord. 2888 § 1, 2007; Ord. 2112 § 2, 1987).

21.07.030 Definitions.Unless specifically defined in this section, words or phrases used in this chapter shall be interpreted so as to give them the meaning they have in common usage and to give this chapter its most reasonable application:

(1) “Appeal” means a request for a review of the interpretation of any provision of this chapter or a request for a variance.

(2) “Area of shallow flooding” means a designated AO or AH zone on the flood insurance rate map (FIRM). AO zones have base flood depths that range from one to three feet above natural ground; a clearly defined channel does not exist; the path of flooding is unpredictable and indeterminate; and velocity flow may be evident. AO is characterized as sheet flow; AH indicates ponding, and is shown with standard base flood elevations.

(3) “Area of special flood hazard” means the land in the floodplain within a community subject to a one percent or greater chance of flooding in any given year. Designation on maps always includes the letters A or V.

(4) “Base flood” means the flood having a one percent chance of being equalled or exceeded in any given year (also referred to as the “100-year flood”). Designated on flood insurance rate maps by the letters A or V.

(5) “Basement” means any area of a building having its floor sub-grade (below ground level) on all sides.

(6) “Breakaway wall” means a wall that is not part of the structural support of the building and is intended through its design and construction to collapse under specific lateral loading forces, without causing damage to the elevated portion of the building or supporting foundation system.

(7) “Compensatory flood storage” means any new, excavated flood storage volume equivalent to any flood storage capacity which has been or would be eliminated by filling or grading within the flood fringe.

(8) “Critical facility” means a facility for which even a slight chance of flooding might be too great. Critical facilities include, but are not limited to, schools, nursing homes, hospitals, police, fire and emergency response installations, and installations which produce, use, or store hazardous materials or hazardous waste.

(9) “Cumulative substantial damage” means flood-related damages sustained by a structure on two separate occasions during a 10-year period for which the cost of repairs at the time of each such flood event, on the average, equals or exceeds 25 percent of the market value of the structure before the damage occurred.

(10) “Development” means any manmade change to improved or unimproved real estate, including but not limited to buildings or other structures, mining, dredging, filling, grading, paving, excavation or drilling operations or storage of equipment or materials located within the area of special flood hazard.

(14) “Expansion to an existing manufactured home park or subdivision” means the preparation of additional sites by the construction of facilities for servicing the lots on which the manufactured homes are to be affixed (including the installation of utilities, the construction of streets, and either final site grading or the pouring of concrete pads).

(15) “Freeboard” means a factor of safety usually expressed in feet above a flood level for purposes of floodplain management. Freeboard tends to compensate for the many unknown factors that could contribute to flood heights

17


Page 3/15


greater than the height calculated for a selected size flood and floodway conditions, such as wave action, bridge openings, and the hydrological effect of urbanization of the watershed.

(16) “Flood” or “flooding” means a general and temporary condition of partial or complete inundation of normally dry land areas from:

(a) The overflow of inland or tidal waters; and/or

(b) The unusual and rapid accumulation of runoff of surface waters from any source.

(17) “Flood insurance rate map (FIRM)” means the official map on which the Federal Insurance Administration has delineated both the areas of special flood hazards and the risk premium zones applicable to the community.

(18) “Flood insurance study (FIS)” means the official report provided by the Federal Insurance Administration that includes flood profiles, and flood boundary-floodway map, and the water surface elevation of the base flood.

Eligibility for an ICC claim can be through a single instance of substantial damage or as a result of cumulative substantial damage.

(21) “Lowest floor” means the lowest floor of the lowest enclosed area (including basement). 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 nonelevation design requirements of this chapter found at PMC 21.07.060.

(22) “Manufactured home” means a structure, transportable in one 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. The term “manufactured home” does not include a recreational vehicle.

(23) “Manufactured home park or subdivision” means a parcel (or contiguous parcels) of land divided into two or more manufactured home lots for rent or sale.

(24) “New construction” means structures for which the start of construction commenced on or after the effective date of the ordinance codified in this chapter.

18


Page 4/15


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 state 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 foundations 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.

(28) “Structure” means a walled and roofed building, including a gas or liquid storage tank that is principally aboveground.

(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;

(c) The term can exclude:

(i) 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

(ii) Any alteration of a structure listed on the National Register of Historic Places or a State Inventory of Historic Places.

(31) “Take” means to harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect any species listed as threatened or endangered under the Endangered Species Act (ESA) (16 U.S.C. 1531-1544), or attempt to engage in any such conduct. For purposes of this definition, harm means an act which actually kills or injures wildlife. Such an act may include significant habitat modification or degradation where it actually kills or injures wildlife by significantly impairing essential behavioral patterns, including breeding, feeding, or sheltering.

(32) “Variance” means a grant of relief from the requirements of this chapter that permits construction in a manner that would otherwise be prohibited by this chapter.

(33) “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. (Ord. 2888 § 1, 2007; Ord. 2268 § 80, 1991; Ord. 2184 § 1, 1988; Ord. 2112 § 2, 1987).

21.07.040 General provisions.(1) Lands to Which This Chapter Applies. This chapter shall apply to all areas of special flood hazards within the jurisdiction of the city.

(2) Basis for Establishing the Areas of Special Flood Hazard. The areas of special flood hazard identified by the Federal Insurance Administration in a scientific and engineering report entitled “The Flood Insurance Study for Pierce County, and Incorporated Areas” dated March 7, 2017, and any revisions thereto, with an accompanying

19


Page 5/15


Flood Insurance Rate Map (FIRM) and any revisions thereto, are hereby adopted by reference and declared to be a part of this ordinance. The Flood Insurance Study and the FIRM are on file at 333 South Meridian, Puyallup, WA 98371. Where the Flood Insurance Study, FIRM, and floodway maps do not provide adequate, best, or most recent information, flood information that is more accurate or detailed may be used. When there is a conflict between the elevations and the mapped potential flood hazard area boundaries, the elevation shall govern.

(3) 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. Violations 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 gross 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 $5,000 or imprisoned for not more than 365 days, or both, for each violation, and in addition shall pay all costs and expenses involved in the case. Nothing contained in this chapter shall prevent the city from taking such other lawful action as is necessary to prevent or remedy any violation.

(4) 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 ordinance, easement, covenant or deed restriction conflict or overlap, whichever imposes the more stringent restrictions shall prevail.

(5) Interpretation. In the interpretation and application of this chapter, all provisions shall be:

(a) Considered as minimum requirements;

(b) Liberally construed in favor of the governing body; and

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

(6) 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 manmade 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 the city, 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 under this chapter. (Ord. 2888 § 1, 2007; Ord. 2112 § 2, 1987).

21.07.050 Administration.(1) 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 PMC 21.07.040(2). The permit shall be for all structures, including manufactured homes, as set forth in PMC 21.07.030, and for all development, including fill and other activities also as set forth in PMC 21.07.030.

(b) Application for Development Permit. Application for a development permit shall be made on forms furnished by the city and may include, but not be limited to, plans in duplicate drawn to scale showing the nature, location, dimensions and elevations of the area in question; existing or proposed structure, fill, storage of materials, drainage facilities and the location of the foregoing. Specifically, the following information is required:

(i) Elevation in relation to mean sea level of the lowest floor (including basement) of all structures recorded on a current elevation certificate

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

(iii) Certification by a registered professional engineer or architect that the floodproofing methods for any nonresidential structure meet the floodproofing criteria in PMC 21.07.060(2)(b);

20


Page 6/15


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

(c) Applicants for development permits shall also submit a habitat assessment prepared by a qualified professional evaluating the effects of the proposed development (during both construction and operation) on the following floodplain functions and documenting that the proposed development will not result in “take” of any species listed as threatened or endangered under the ESA:

(i) water quantity and quality (including preparing a hydrologic and hydraulic analyses in accordance with standard engineering practice); This is required for development that is concluding that compensatory storage of less than 1:1 is necessary to avoid ‘take’ of any species listed.

(ii) flood storage capacity;

(iii) channel migration and bank stability;

(iv) riparian vegetation;

(v) habitat forming processes (such as large wood recruitment) and habitat isolation;

(vi) refuge for fish from higher velocity floodwaters; and

(vii) spawning substrate.

Development Permits will be denied if the proposal will result in “take” of any species listed as threatened or endangered under the ESA, unless the applicant provides the City with evidence that the federal and state permits required to authorize such take have been obtained.

(2) Designation of the City. The city is appointed to administer and implement the ordinance codified in this chapter by granting or denying development permit applications in accordance with its provisions.

(3) Duties and Responsibilities of the City. Duties of the city shall include, but not be limited to:

(a) Permit Review.

(i) Review all development permits within 28 calendar days of submittal to determine if the application is complete and shall follow the procedures set forth in PMC 20.11.006.

Upon acceptance of the application as complete, the city shall review the development permit to determine that the permit requirements of this chapter have been satisfied.

(ii) 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.

(iii) Review all development permits to determine if the proposed development is located in the floodway. If located in the floodway, assure that the encroachment provisions of PMC 21.07.060(3)(a) are met.

(b) Use of Other Base Flood Data. When base flood elevation data has not been provided (in A or V zones) in accordance with PMC 21.07.040(2), Basis for Establishing the Areas of Special Flood Hazard, the city shall obtain, review and reasonably utilize any base flood elevation and floodway data available from the federal, state or other source, in order to administer PMC 21.07.060(2), Specific Standards, and PMC 21.07.060(3), Floodways.

(c) Information to be Obtained and Maintained.

(i) Where base flood elevation data is provided through the flood insurance study, flood insurance rate map, or required as in subsection (3)(b) of this section, obtain and record the actual (as-built) elevation (in

21


Page 7/15


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.

(ii) For all new or substantially improved floodproofed nonresidential structures:

(A) Verify and record the actual elevation (in relation to mean sea level) to which the structure was floodproofed; and

(B) Maintain the floodproofing certification required in subsection (1)(b)(iii) of this section.

(iii) Maintain for public inspection all records pertaining to the provisions of this chapter.

(d) Alteration of Watercourses.

(i) Notify adjacent communities and the Department of Ecology prior to any alteration or relocation of a watercourse, and submit evidence of such notification to the Federal Insurance Administration.

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

(e) 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 a 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 in subsection (4) of this section.

(4) Variance Procedure.

(a) Conditions for Variances.

(i) 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, provided subsections (4)(b)(iv)(A) through (K) of this section have been fully considered. As the lot size increases, the technical justification required for issuing the variance increases.

(ii) 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.

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

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

(v) 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 (4)(b)(iv) of this section, or conflict with existing local laws or ordinances.

22


Page 8/15


(vi) 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 following elevations should be quite rare.

(vii) 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 subsection (4)(a)(iv) of this section, and otherwise complies with PMC 21.07.060(1)(a) and (2) of the general standards.

(viii) Any applicant to whom a variance is granted shall be given written notice that the structure will be permitted to be built with a lower 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.

(Ord. 2888 § 1, 2007; Ord. 2479 § 1, 1996; Ord. 2268 § 81, 1991; Ord. 2112 § 2, 1987).

21.07.060 Provisions for flood hazard reduction.(1) General Standards. In all areas of special flood hazards, the following standards are required:

(a) Anchoring.

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

(ii) 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’s “Manufactured Home Installation in Flood Hazard Areas” guidebook for additional techniques).

(b) Construction Materials and Methods.

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

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

(iii) 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.

(c) Utilities.

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

(ii) 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;

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

(iv) Water wells shall be located on high ground that is not in the floodway.

(d) Subdivision Proposals.

24


Page 10/15


(i) All subdivision proposals shall be consistent with the need to minimize flood damage;

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

(iii) All subdivision proposals shall have adequate drainage provided to reduce exposure to flood damage; and

(iv) 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 50 lots or five acres (whichever is less).

(e) Review of Building Permits. Where elevation data is not available either through the flood insurance study, flood insurance rate maps, or from another authoritative source, applications for building permits shall be reviewed to assure that proposed construction will be reasonably safe from flooding. The test of reasonableness is a city judgment and includes use of historical data, high water marks, photographs of past flooding, etc., where available. Failure to elevate at least two feet above grade in these zones may result in higher insurance rates.

(f) Compensatory Storage.

(1) Except as set forth in subsection (2) below, development proposals that will cause an increase in the water surface elevation of the base flood must provide compensatory storage to the extent necessary to avoid “take” of any species listed as threatened or endangered under the ESA. Such compensatory storage must:

(a) Provide equivalent elevations to that displaced-unless the project is located within the AO Zone. AO Zone projects are not required to comply with the equivalent elevation requirement;

(b) Be hydraulically connected to the source of flooding;

(c) Be provided in the same construction season and before the flood season begins on September 30th;

(d) Occur on site or off site if legal arrangements can be made to assure that the effective compensatory storage volume will be preserved over time; and

(e) Be supported by a detailed hydraulic analysis that is prepared by a licensed professional engineer.

(2) For development proposals on single family residential lots, the applicant shall either:

(a) comply with the compensatory storage requirements as set forth in subsection (1)(a)-(e) above; or

(b) provide compensatory storage in an amount equal to the flood storage volume filled or displaced by the development (1:1 fill to compensatory storage).

Where applicants utilize subsection (f)(2)(b), such compensatory storage shall also comply with the provisions of subsection (f)(1)(a)-(d), but no detailed hydraulic analysis shall be required.

(2) Specific Standards. In all areas of special flood hazards where base flood elevation data has been provided as set forth in PMC 21.07.040(2), Basis for Establishing the Areas of Special Flood Hazard, or PMC 21.07.050(3)(b), Use of Other Base Flood Data. Additional standards, with varying impacts on flood insurance premium rates, are provided in FEMA Technical Bulletin 11-01. The following provisions are required:

(a) Residential Construction.

25


Page 11/15


(i) Except in AO zones which are regulated under subsection 5 below, new construction and substantial improvement of any residential structure shall have the lowest floor, including basement, elevated to a minimum of one foot or more above base flood elevation. Addition of additional freeboard increases safety and can reduce insurance premiums.

(ii) 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:

(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 or devices; provided, that they permit the automatic entry and exit of floodwaters;

(D) Additional requirements for below-grade crawlspaces:

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

2. 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. This limitation will also prevent these crawlspaces from being converted into habitable spaces.

3. 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.

4. 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 foundations should be used.

5. 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.

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

26


Page 12/15


(b) Nonresidential Construction. Except in AO zones which are regulated under subsection 5 below, new construction and substantial improvement of any commercial, industrial or other nonresidential structure shall either have the lowest floor, including basement, elevated to a level of a minimum of one foot or more above base flood elevation; or together with attendant utility and sanitary facilities, shall:

(i) Be floodproofed so that below one foot above the regulatory flood level the structure is watertight with walls substantially impermeable to the passage of water;

(ii) Have structural components capable of resisting hydrostatic and hydrodynamic loads and effects of buoyancy;

(iii) 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 PMC 21.07.050(3)(c)(ii);

(iv) Nonresidential structures that are elevated, not floodproofed, must meet the same standards for space below the lowest floor as described in subsection (2)(a)(ii) of this section;

(v) Applicants floodproofing nonresidential buildings shall be notified that flood insurance premiums will be based on rates that are one foot below the floodproofed level (e.g., a building constructed to the base flood level will be rated as one foot below that level). Floodproofing the building an additional foot will reduce insurance premiums significantly.

(c) Critical Facility. Construction of new facilities shall be, to the extent possible, located outside the limits of the base floodplain (shown as special flood hazard areas, SFHA, on floodplain maps). 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 or to the height of the 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 floodwaters. Access routes elevated to or above the level of the base floodplain shall be provided to all critical facilities to the extent possible.

(d) Manufactured Homes. All manufactured homes to be placed or substantially improved in the floodplain within zones A1 – 30, AH, and AE on the community’s FIRM shall be elevated on a permanent foundation such that the lowest floor of the manufactured home is elevated one foot or more above the base flood elevation

27


Page 13/15


and be securely anchored to an adequately anchored foundation system in accordance with the provisions of subsection (1)(a)(ii) of this section.

(e) Recreational Vehicles. Recreational vehicles placed on sites within AO zones within flood zones (exceptAO zones) are required to either.

(i) Be on the site for fewer than 180 consecutive days; or

(ii) 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

(iii) Meet the requirements of subsection (2)(d) of this section and the elevation and anchoring requirements for manufactured homes (subsection (2)(d) of this section).

(3) Floodways. Located within areas of special flood hazard established in PMC 21.07.040(2) are areas designated as floodways. Since the floodway is an extremely hazardous area due to the velocity of floodwaters that can carry debris and increase erosion potential, the following provisions apply:

(a) Prohibit encroachments, including fill, new construction, substantial improvements, and other development unless certification by a registered professional engineer is provided demonstrating through hydrologic and hydraulic analyses performed in accordance with standard engineering practice that the proposed encroachment shall not result in any increase in flood levels during the occurrence of the base flood discharge.

(b) If subsection (3)(a) of this section is satisfied, all new construction and substantial improvements shall comply with all applicable flood hazard reduction provisions of this section.

(c) Construction or reconstruction of residential structures is prohibited within designated floodways, except for:

(i) Repairs, reconstruction, or improvements to a structure which do not increase the ground floor area; and

(ii) Repairs, reconstruction or improvements to a structure, the cost of which does not exceed 50 percent of the market value of the structure either:

(A) Before the repair, reconstruction, or repair is started, or

(B) If the structure has been damaged, and is being restored, before the damage occurred;

(iii) Any project for improvement of a structure to correct existing violations of state or local health, sanitary, or safety code specifications which have been identified by the local code enforcement official and which are the minimum necessary to assure safe living conditions, or to structures identified as historic places, may be excluded in the 50 percent;

(iv) If subsections (3)(a) and (b) of this section are satisfied, all new construction and substantial improvements shall comply with all applicable flood hazard reduction provisions of this section.

(d) Wetlands Management. To the maximum extent possible, avoid the short- and long-term adverse impacts associated with the destruction or modification of wetlands, especially those activities that limit or disrupt the ability of the wetland to alleviate flooding impacts. The following process should be implemented:

(i) Review proposals for development within base floodplains for their possible impacts on wetlands located within the floodplain.

(ii) Ensure that development activities in or around wetlands do not negatively affect public safety, health, and welfare by disrupting the wetlands’ ability to reduce flood and storm drainage.

28


Page 14/15


(iii) Request technical assistance from the Department of Ecology in identifying wetland areas. Existing wetland map information from the National Wetlands Inventory (NWI) can be used in conjunction with the community’s FIRM to prepare an overlay zone indicating critical wetland areas deserving special attention.

(4) AE and A1 – 30 Zones with Base Flood Elevations But No Floodways. 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 foot at any point within the community unless the applicant provides compensatory storage consistent with the provisions of subsection (1)(f) above.

(5) Standards for Shallow Flooding Areas (AO Zones). Shallow flooding areas appear on FIRMs as AO zones with depth designations. The base flood depths in these zones range from one to three feet where a clearly defined channel does not exist, or where the path of flooding is unpredictable and where velocity flow may be evident. Such flooding is usually characterized as sheet flow. In these areas, the following provisions (in addition to the requirements set forth in subsection (1)) apply:

(a) New construction and substantial improvements of residential structures within AO zones shall have the lowest floor (including basement) elevated above the highest adjacent grade of the structure, one foot or more above (as recorded on a current elevation certificate, FF 81-31, with Section E completed) the depth number specified in feet on the community’s FIRM (at least two feet above the highest adjacent grade to the structure if no depth number is specified).

(b) New construction and substantial improvements of nonresidential structures within AO zones shall either:

(i) Have the lowest floor (including basement) elevated above the grade of the building site, one foot or more above the depth number specified on the FIRM (at least two feet if no depth number is specified); or

(ii) Together with attendant utility and sanitary facilities, be completely floodproofed to or above that level so that any space below that level is watertight with walls substantially impermeable to the passage of water and with structural components having the capability of resisting hydrostatic and hydrodynamic loads and effect of buoyancy. If this method is used, compliance shall be certified by a registered professional engineer or architect as in subsection (2)(b)(iii) of this section.

(c) Require adequate drainage paths around structures on slopes to guide floodwaters around and away from proposed structures.

(d) The habitable space of a building shall be constructed to an elevation at least one foot above the crown of the public street. The engineering department shall make a determination whether the crown of the existing street is at finished elevation. If the street is not at finished elevation, the engineering department shall require that the finished elevation of the street be determined by a professional engineer.

(i) Where hazardous velocities were noted on the FIRM, measures mitigating the effects of these velocities through proper construction techniques and methods shall be undertaken. The engineering department may require that a professional engineer prepare the mitigating measures.

(e) Require adequate drainage paths around structures on slopes to guide floodwaters around and away from proposed structures.

(6) Compensatory Storage. Development proposals must not reduce the effective base flood storage volume of the area of special flood hazard. Grading or other activity that would reduce the effective storage volume must be mitigated by creating compensatory storage on the site. The compensatory storage must:

(a) Provide equivalent elevations to that displaced-unless the project is located within the AO Zone. AO Zone projects are not required to comply with the equivalent elevation requirement;

29


Page 15/15


(b) Be hydraulically connected to the source of flooding;

(c) Be provided in the same construction season and before the flood season begins on September 30th;

(d) Occur on site or off site if legal arrangements can be made to assure that the effective compensatory storage volume will be preserved over time;

(e) Be supported by a detailed hydraulic analysis that;

(i) Is prepared by a licensed professional engineer; and

(ii) Demonstrates that the proposed compensatory storage does not adversely affect the BFE.
