      (9)   Review process. Site plan review within the TC Overlay District shall be conducted before the City Planning Commission, as specified below:
         (a)   For a new structure;
         (b)   For an exterior structural addition, exterior extension, exterior remodeling or other exterior development that does not increase the useable mass of the building, site plan review is not required and compliance with the standards in this section shall be processed as an administrative action;
         (c)   For an exterior structural addition, exterior extension, exterior remodeling or other exterior development which increases the useable mass of the building; and
         (d)   In processing administrative requests, the City Planner may waive selected submittal requirements if they are not necessary to determining compliance with this section. In addition, the City Planner may forward any request to the Planning Commission for review if the scale or nature of the proposal merits broader review.
      (10)   All reviews shall meet the requirements listed in division (G) below.
   (G)   General provisions. All development in the Town Center Overlay District shall meet the following requirements.
      (1)   Height regulations. No building or structure (including signage) shall hereafter be erected, enlarged or structurally altered to exceed a height of 50 feet. For exceptions, see § 152.050.
      (2)   Density. For properties on Main Avenue between First Street and Fourth Street and Second Street between Ivy Avenue and Pacific Avenue, buildings shall be a minimum of two stories and a maximum of four stories, with a zero foot setback for all floors. Continuous storefronts shall occupy one hundred 100% of the parcel width at the front setback line.
      (3)   Lot requirements.
         (a)   Lot area. No maximum lot area.
         (b)   Lot width/depth. Building width:
            1.   The width should not exceed that which was traditional for the building styles of the Town Center dated prior to 1950; and
            2.   The width should maintain the traditional scale and proportion of the building style and be visually compatible with historic design as described in division (H) below and illustrated in division (H)(3). Where building sizes will not be equivalent or comparable, larger building facades shall be broken down into units that resemble the size of existing storefront facades.
         (c)   Front yard setback. Minimum of zero feet and a maximum of ten feet. The ten-foot maximum applies to the first 15 feet of building height only. Upper stories may step back for balconies or other outdoor space. For exceptions, see division (I) below. The ten-foot maximum setback area may be used only for plazas, outdoor seating or other useable pedestrian space related to the adjacent business. See division (G)(4)(b) below for building frontage requirements.
         (d)   Side yard setback. No requirements.
         (e)   Rear yard setback. No requirements.
      (4)   Site building design standards. The following standards are intended to promote a desired level of future development quality that will stimulate investment and strengthen economic vitality in the Town Center, and renew a positive physical image of the downtown core.
         (a)   Building orientation. All new buildings shall be oriented to public streets. Building orientation is demonstrated by placing buildings and their public entrances close to streets so that pedestrians have a direct and convenient route from the street sidewalk to building entrances. Off-street parking or vehicular circulation shall not be placed between buildings and streets used to comply with this standard.
         (b)   Building frontage. On sites with 100 feet or more of public street frontage, at least 80% of the site width shall be occupied by buildings placed within the maximum setback. For sites with less than 100 feet of public or private street frontage, at least 60% of the site width shall be occupied by buildings placed within the maximum setback.
         (c)   Differentiation between spaces. Differentiation shall be provided between ground-level spaces and upper stories. For example, bays or balconies for upper levels, and awnings, canopies or other similar treatments for lower levels can provide differentiation. Variation in building materials, trim, paint, ornamentation, windows or other features such as public art may also be used.
         (d)   Ground floor windows and openings in the surface of a structure. Ground floor windows and openings in the structure surface shall be provided on the first floor building facade that faces a street. The main front elevation(s) of buildings shall provide 60% to 80% windows, transparencies or other openings at the pedestrian level (on corner lots, this provision applies to two elevations).
         (e)   Commercial storefront. The continuous commercial fronts of the Town Center make for a consistent, pedestrian friendly streetscape for a wide variety of businesses. The storefront is predominately made up of glazing with only structure and decoration revealed. The upper stories consist mostly of walls with “punched” window openings. New construction and rehabilitation should maintain the continuity of the multi-story buildings and the clear distinction between street level storefront and upper floor offices or residences through facade treatment and articulation.
            1.   Entrances.
               a.   Primary entrances should be recessed, glazed and oriented to the street rather than to a rear or interior alley.
               b.   Tiled floors should be used as they are highly effective in marking the recessed entrance.
            2.   Windows.
               a.   Changing the location or size of windows or other openings that alter the architectural rhythm, alignment or character of the original building is prohibited.
               b.   Except for transom windows, windows should not break the plane of the facade.
               c.   Clear plate glass should be used for display windows, and they should be incorporated with transom windows.
               d.   Storefront windows shall be no closer than 18 inches from the ground (bulkhead height). The maximum bulkhead height for new construction should be 36 inches.
               e.   Vertical, double-hung windows, either singly or in groups, should be used on the upper levels.
               f.   When considering new window fenestration (window size, size of window panes, mullion type window materials), it is important that the new design be sympathetic and compatible with the facade theme of the whole block.
               g.   Obstructing or covering mezzanine windows is discouraged.
            3.   Storefront facades.
               a.   Vertical structural lines (columns, piers, window patterns) should be carried down to the ground. If the lower storefront materials are different, use similar colors and forms to integrate the building facade.
               b.   Non-historic materials above or below storefront windows (such as small areas of decorative stone) should be replaced with material of craftsmanship, color and texture that distinguishes historic from other buildings.
               c.   Street level columns and bays for display windows should be preserved or used. They should provide a clear visual division at the property line.
               d.   Doors should be accentuated with simple details such as a handsome brass door pull, brass kickplate or an attractive painted sign.
         (f)   Roof form.
            1.   Roof forms contribute to the identity of the Town Center because historically they were flat with parapets, false fronts or gables concealed by a parapet or false front, in contrast to the pitched roofs in the residential neighborhoods. New construction and rehabilitation should maintain the traditional storefront architecture of the downtown in articulation of its roof forms along the street edge.
               a.   Roof forms should be consistent with those commercial buildings of the key historic period of the Town Center which is dated prior to 1950.
               b.   Parapet and flat roofs are recommended. Pitched roof forms associated with residential structures are not recommended, unless concealed by a parapet.
               c.   Detailing of the parapets with patterned or relief cornices and stepping is recommended.
               d.   Tile, shake shingle and thick composition roofs are strongly encouraged. Standing seam metal, corrugated metal, fiberglass, high contrast or brightly colored glazed tile, and crushed rock roofs are prohibited.
            2.   Roof-mounted equipment (e.g., HVAC) shall be screened from view from the street by providing a parapet or cornice at least equal in height to the equipment and by painting the equipment to match the roof. For flat roofs, the parapet shall surround the perimeter of the building. Screening shall be compatible with rooflines and materials so that the rooflines are harmonious.
         (g)   Cornices and architectural detail. Cornices are important architectural elements. They give interest to the roofline, breaking up the flat lines of a straight parapet wall; they give a building its own individuality.
            1.   Repair existing cornices if they have been covered up, remove the applied materials and restore; if they have been removed, consider replacing.
            2.   Sheet metal cap flashing should be kept to a minimum unless the building has a flat parapet wall.
            3.   If a building has decorative architectural details, clean them to restore their original character or paint them in contrasting colors to accentuate them.
         (h)   Marquees. Marquees provide a “ceiling” for pedestrian traffic, which helps to give a sense of enclosure to the street and protection from the elements. All new or replacement awnings/overhangs must be marquee style.
            1.   Marquees should fit within window bays so as not to detract from architectural features of the building or obscure transom windows above display windows.
            2.   Marquees may pass over vertical columns or pilasters.
            3.   The color of the awning should be compatible with the building.
            4.   The marquees shall be flat, horizontal metal canopies suspended by chains or rods, if original, should be used as they provide cover for pedestrians and shade within the store.
            5.   The use of internally illuminated, plastic and/or barrel awnings are prohibited as they detract from architectural features with incompatible materials that are out of scale.
         (i)   Color. Color can dramatically affect the appearance of buildings and should be kept clean and in good repair and carefully considered in relation to the overall design of the building. Color can also affect the apparent scale and proportion of buildings by highlighting architectural elements such as doors and windows.
            1.   Historic masonry facades should not be painted.
            2.   Minimize the number of colors on the building’s exterior in order to maintain a cohesive appearance with minimum visual distraction. Commercial buildings shall use no more than four colors.
            3.   The color palette chosen for a building should be compatible with the colors of adjacent buildings in the Town Center.
            4.   Colors must be selected from the color chart approved by City Council resolution. Bright neon paint colors and large areas of intense white colors shall be avoided.
         (j)   Rear entrances.
            1.   Signs should be modestly scaled to fit the casual visual character of the alley or rear parking area.
            2.   An awning can soften rear facades and provide a pleasant protected space.
            3.   The rear entry door should be wood and glass similar to the front door.
            4.   Security lighting should be modest and should focus on the rear entry door.
            5.   Selective use of tree plantings, potted plants and other landscaping can subtly improve a rear facade.
            6.   Refuse containers and service facilities should be screened from view by solid masonry walls and landscaping to screen walls and help deter graffiti.
      (5)   Landscaping and screening. Landscaping and screening shall be required, in accordance with the following standards. (These standards apply in the TC District and supersede the landscape standards in other sections of this chapter.):
         (a)   All areas not occupied by structures, parking lots or pedestrian plazas that are visible from public right-of-ways shall provide landscaping. Landscaping shall include a mix of vertical and horizontal elements.
         (b)   Street trees shall be required on at least one side of all streets except Main and Pacific Avenues between First and Fourth Streets. Species should be compatible with the design features provided below, and shall provide continuity with nearby landscaping. Street tree species to be planted and minimum tree planting dimensions are described in § 152.053. A reduction to the number of required street trees may be granted when a development preserves healthy, mature tree(s) adjacent to the sidewalk.
            1.   Tree canopies shall be a minimum of ten feet diameter.
            2.   Trunk setback from curb shall be a minimum distance of two and one-half feet, maximum distance of three feet.
         (c)   Screening of parking areas, drives, mechanical equipment and solid waste receptacles with screening elements is required and shall be installed prior to building occupancy. Screening options include landscape plants, planters, ornamental walls, trellises, fences or other features approved by the City Planner.
         (d)   Drought-resistant vegetation is strongly encouraged. Irrigation systems shall be installed to support landscaping that is not drought-resistant.
         (e)   Streetscape:
            1.   The Town Center is a pedestrian friendly environment with a combination of features: storefronts, sidewalks, streetlights and other amenities. New construction and rehabilitation should contribute to making it an inhabitable place pleasant for walking, providing a buffer zone of parked cars between automobile traffic and pedestrians, reinforcing the rhythm of the street in accordance with the Town Center Master Plan and Resolution 1625.
            2.   The following items can be included as landscaping as required in § 152.053.
               a.   Places for public activities. Informational kiosks, historical markers and flagpoles are encouraged;
               b.   Drinking water fountains, places to sit and rest, places to stand out of the rain or sun with accessible benches out of pedestrian flow;
               c.   Removal of unsightly signs and unused sign supports; signs better relating to the pedestrian installed;
               d.   Streetlights and sidewalk elements not obscuring line of vision from automobiles;
               e.   Historically appropriate streetlights installed;
               f.   Trash receptacles attractive, serviceable, durable and easily maintained; and
               g.   Street trees on all streets in the Town Center Overlay District.
      (6)   Signs.
         (a)   Signs should not be the dominant feature of a building or site, yet they are a key component in identifying businesses and contributing to the livelihood of the street with their individuality. Standards in this section do not apply to window signs or signs in the right-of-way. Signs should allow for pedestrian and automobile traffic to identify businesses without detracting from the architecture or overpowering the streetscape. (Note: Signs that extend into the right-of-way (ROW) but are attached to the building and signs on the property require a sign permit for approval. Other signs not attached to buildings on property but located in the ROW require a ROW use permit for approval.)
 
         (b)   Signs in the Town Center Overlay shall be allowed subject to the following conditions.
            1.   On-building wall signs, canopy signs and blade signs attached to buildings shall be allowed subject to the following requirements.
               a.   A maximum of three such signs shall be allowed per street frontage building side.
               b.   On-building signs shall be incorporated into the design of the building, shall be compatible in scale and shall not be placed in locations which interrupt, detract from or change the architectural character and features of the building.
            2.   Marquee signs shall be allowed subject to the following requirements:
               a.   A maximum of three such signs shall be allowed per building side;
               b.   Must be located within one inch of the top and bottom of the marquee with no more than three businesses indicated per marquee; and
               c.   Marquee signs shall be incorporated into the design of the building, shall be compatible in scale and shall not be placed in locations which interrupt, detract from or change the architectural character and features of the building.
            3.   Lit and illuminated signs:
               a.   A maximum of one such signs shall be allowed per business.
               b.   All signs, if lighted, must be by indirect illumination or lit.
               c.   All lighted signs must be in a manner as to not disturb neighboring property.

               g.   All molded plastic or acrylic signs must conform to the style of the era from the 1940s to 1950s.
               h.   Signs at the rear side of the buildings should be modestly scaled to fit the casual visual character of the alley or rear parking area.
 
            5.   Signs in the Town Center exempt to these requirements and are not included in the required sign face area:
               a.   Portable signs;
               b.   Window signs;
               c.   Incidental signs;

               f.   Political signs and shall meet the requirements listed in § 152.055.
      (7)   Off-street parking, loading and circulation requirements.
         (a)   For commercial uses in the Town Center Overlay District, off-street parking is not required. For residential uses, parking shall be provided at a minimum of one space per dwelling unit and a maximum of one space per bedroom. Exceptions to the minimum requirement may be approved by the city when it is demonstrated that the type of housing proposed does not require parking, and/or when it is shown that use of on-street spaces during off-peak hours will provide adequate parking for the area. Civic uses shall provide parking consistent with the requirements of § 152.054.

Loading and service areas shall be located to the rear or sides of buildings, or in alleys when available. Loading dock doors are encouraged to be placed in recessed areas or between buildings to minimize impacts to the pedestrian and human-scale aspects of the development.
         (e)   1.   Off-street parking areas shall be separated from buildings by either a raised concrete walkway or landscaped strip with a minimum width of six feet.
            2.   Situations where parking stalls directly abut buildings shall be avoided except where wheel stops are provided.
         (f)   Off-street parking areas shall be screened from the street by a street wall or arcade between six feet and 15 feet in height, and extending a maximum width to screen the view of parked vehicles and allow for safe circulation at the minimum driveway widths required according to § 152.054.
         (g)   Rear parking lots shall be designed and located contiguous to each other to the greatest extent practicable so that vehicles can travel from one private parking lot to the other (reciprocal access) without having to enter the street. Shared parking and circulation aisles coordinated between adjacent businesses and/or developments are strongly encouraged.

§ 152.033 LIMITED USE OVERLAY DISTRICT (LU DISTRICT).

   (A)   Purpose. To allow permitted uses in the underlying zone to only those that were justified in the Averill mediation agreement, subject to those findings and conditions detailed in that agreement.
   (B)   Application.
      (1)   Uses permitted in the underlying zone shall be limited to those uses specifically referenced in the Comprehensive Plan amendment/zone change and any accompanying conditions set forth.
      (2)   The limited use overlay shall not be used to authorize uses not expressly provided for in the underlying zone.
      (3)   The limited use overlay shall apply to the property until it is specifically removed as the result of the parties not maintaining a majority ownership in the subject property (as per mediation agreement).
      (4)   The following limitations shall apply to application of the limited use overlay.
         (a)   Sound barriers. Averill shall erect a sound barrier of evergreen trees of a type to be specified by the city along the north river bank of said property, immediately upon the appeal period to LUBA running and the order becoming final. In the event that all or portions of the sound barrier do not thrive, they shall be replaced with new sound barrier vegetation until the vegetation, as needed, is well established.
         (b)   Noise reduction. The operation of Averill’s trucks as they travel over the means of ingress and egress from Highway 101 North shall be at a slow speed and in a manner so as not to cause unreasonable vibrations and/or noise which interferes with the reasonable enjoyment of the occupants of neighboring property.
         (c)   Gravel. Averill shall maintain the gravel portion of Werner Road to his westerly property line in good passable condition by passenger cars.
         (d)   Sewer. Averill, at his sole expense, will connect the subject property to city water and sewer within 45 days after the appeal period has expired from the order described in Paragraph 1 of the mediation agreement.
         (e)   ODOT. Within 45 days after the appeal period for the Board of County Commissioners’ order described in division (B)(1) above having run, Averill will apply for a temporary permit from the State Department of Transportation subject to the following conditions.
            1.   Averill shall construct and/or install, at his sole expense, physical barriers at the Werner Road-Highway 101 junction to prevent left turns from Werner Road northbound onto Highway 101. The barrier system and appropriate signage shall be State Department of Transportation approved. Said temporary permit shall remain in force only until such time as permanent access is constructed in conjunction with the highway improvement project for this portion of Highway 101.
            2.   Any permit would be conditioned upon Averill’s use of the subject parcel being substantially similar to the current use. So long as the truck trips are within 10% of the current use as described in division (B)(4)(f) below, it shall be deemed a substantially similar use.
            3.   The provisions of this section shall be added as a condition of the land use overlay described in division (B)(4)(i) below.
         (f)   Current use.
            1.   For purposes of this overlay zone, the following definitions shall be used:
                  SITE. The six and one-half acres;
                  TRUCK TRIP. Equals not more than four vehicle movements; and
                  VEHICLE MOVEMENT. Two vehicle axles passing over a vehicle counter so calibrated.
            2.   Averill’s current use is comprised of the average daily trips entering or exiting the site in any 24-hour period, the existing surfaced working maneuvering, parking and storage area, including trucking and access.
            3.   The parties have agreed that traffic on Werner Road averages 490 vehicular movements per day and that truck movements from Averill’s trucking business account for 80% of those movements which was agreed to equal 100 truck trips per day.
            4.   Averill shall be deemed in compliance with the terms of this overlay zone so long as the truck trips from Averill’s business do not exceed 110 truck trips per day averaged over any 30 consecutive day period.
         (g)   Use. The use of the subject property shall be limited to the existing trucking facility. The use shall be those uses allowed by law and reviewed at each subsequent review of the city pursuant to O.A.R. 660, Division 25.
         (h)   Improvements. Averill shall not add any further site improvements or additional structures not set forth herein, or otherwise change the character or increase the intensity of use. Potential improvements/additions which are contemplated by Averill and which are specifically exempt from this provision are the addition of a 1,000 gallon lubricating oil tank; and a 35 by 100 foot washing structure with slab foundation and gutters for the purpose of containing potential hazardous waste runoff to the surrounding properties, said structure to be located and attached to the south end of the existing structure on the existing fill. In addition, nothing in this provision shall prohibit Averill from making any changes, improvements or additions which are required by state, federal or local laws or ordinances.
         (i)   Limited land use overlay. Within six months of the expiration of the appeal period from the Board of County Commissioners’ final action on the order described in Paragraph 1 of said mediation agreement, the city shall add a provision to its zoning ordinance allowing for a “limited land use overlay zone” and apply it to the six and one-half acre Averill site. The plan amendment and zone amendment and their application to the Averill site shall be subject to public review pursuant to the post acknowledgment review process for plan and zone amendments. The limited land use overlay zone shall not contain more restrictive conditions than exist in this settlement agreement. The conditions of this agreement shall be applied to the limited land use overlay zone specifically for the Averill property. Any change in ownership of the property which would result in Donald G. Averill and Jo L. Averill not having a majority ownership interest in the property is a basis for the city to review the continued application of a limited land use overlay zone. Specifically excluded from this provision is any incorporation of the trucking business in which Donald G. Averill and Jo L. Averill would retain a majority ownership interest.
         (j)   Laws and regulations. Averill will abide by all laws and regulations which may apply to this property, including, but not limited to, its floodplain designation or any wetlands designation.
   (C)   Procedure. The application of the limited use overlay is consistent with policies of the Comprehensive Plan.
   (D)   Official plan/zoning map. The official plan/zoning map shall be amended to note the application of the limited use overlay to the applicable parcels.
   (E)   Site plan requirements.
      (1)   In addition to limiting the uses permitted through the Comprehensive Plan amendment, the trucking facility was determined to be an outright use in the underlying H-C Zone.
      (2)   All other requirements of the underlying zone remain in effect. The trucking facility shall not add any further site improvements except those stated in division (B)(4)(h) above.

§ 152.035 HAZARD OVERLAY ZONE (HO DISTRICT).

   (A)   Purpose. The purpose of this overlay zone is to avoid development hazards in the areas of the city and the urban growth boundary, which have been mapped as inundation zones (limit construction of new essential facilities and special occupancy structures as defined in O.R.S. 455.447 in tsunami inundation zones). The following special regulations apply to all properties, which lie wholly or partially within one or more of these areas (refer to tsunami hazard map of the city quadrangle).
   (B)   Scope.
      (1)   Protect life and property from natural disasters and hazards.
      (2)   Provide appropriate safeguards to protect development from natural hazards.
   (C)   Authorization. In addition to complying with the provisions of the underlying zoning district, uses and activities shall comply with the provisions of this overlay zone, as required by O.R.S. 455.447.
   (D)   Hazard Overlay Zone boundaries. The boundaries of the HO District Zone shall be the same as the boundaries of the Cascadia Subduction Zone Tsunami Inundation Zone map for the city. These areas shall be part of the zoning ordinance. The underlying zoning district regulations shall remain in effect and all development shall be subject to the requirements of both the underlying zone district and the Hazards Overlay Zone.
   (E)   Site investigation required.
      (1)   A site investigation shall be required by the city for subdivision, partitioning, conditional use or other site development approved by the City Planning Commission in the Hazards Overlay Zone. The city planning official shall require the site investigation in all land use applications handled administratively in which City Planning Commission approval is not required. Site investigation reports shall be performed by an especially qualified engineer or engineering geologist registered by the state to practice as such, in areas requiring specialized knowledge, such as Tsunami Inundation Zones, the city may require that a person with experience or training in such areas be employed.
      (2)   Essential facilities and new special occupancy structures shall not be constructed in Tsunami Inundation Zones established by Department of Geology and Minerals Industries (DOGAMI), unless specifically exempted by O.R.S. 455.446 or given an exception by the DOGAMI governing board.
      (3)   New “essential facilities”, special occupancy structures and all new hazardous facilities and major structures defined in O.R.S. 455.447 that are constructed in a Tsunami Inundation Zone are mandated to seek advice from DOGAMI.
   (F)   Method for minimizing Inundation Zone hazards.
      (1)   The owner or developer will have a new site investigation report made for the site prepared to determine the nature and extent of inundation area on the site, unless the Planning Commission determines that an adequate site investigation report has already been undertaken.
      (2)   The method used to conduct the site investigation report must be acceptable to a qualified engineering geologist and acknowledged by DOGAMI.
         (a)   The report shall be based on historical inundation information.
         (b)   In situations where similar source, tectonic and coastal environments exist and modeled inundation has been done elsewhere, interpolate inundation based on maximum modeled inundation in nearby/bounding areas.
            1.   If available, use low resolution, regional simulations to estimate the relative amplification of tsunamis by offshore bathymetric effects.
            2.   Interpolation should take into account the behavior of tsunamis of similar size for terrain analogous to that of the target area.
         (c)   The report should extrapolate lower-resolution model data on land to estimate inundation and add a safety factor for both inundation and elevation. Extrapolation should take into account the behavior of tsunamis of similar size for terrain analogous to that of the target area, even for tsunamis from other parts of the world.
         (d)   In the absence of other tsunami hazard information, consultation with your NTHMP scientific representative, for tsunami evacuation planning.
      (3)   If the detailed site investigation report indicates that significant amounts of inundation area are in locations required for development, the developer or owner shall have a report prepared by a qualified engineering geologist, which indicates suitable techniques to minimize potential hazards to facilities on the parcel, adjacent and nearby property.
      (4)   Buildings identified for vertical evacuation should have the following characteristics:
         (a)   Designed and built using modern structural engineering;
         (b)   Constructed of reinforced concrete or steel; and
         (c)   Well maintained with buildings materials in good condition.
   (G)   Conditional uses. The following conditional uses may be permitted subject to a conditional use permit: transportation facilities and improvements:
      (1)   Transportation projects that are not designated improvements in the Transportation System Plan; and
      (2)   Transportation projects that are not designated and constructed as part of an approved subdivision or partition.

§ 152.036 WATER RESOURCES PROTECTION OVERLAY DISTRICT (WRPO DISTRICT).

   (A)   Purpose. The purpose of the Water Resources Protection Overlay (WRPO) District is to implement the city significant wetland and riparian policies of the city’s Comprehensive Plan and to guide development and conservation of significant wetlands, streams and riparian corridors identified in the city significant riparian/wetlands inventory (Local Riparian/Wetlands Inventory) and on the city significant wetlands and riparian corridor map (significant wetlands and riparian corridor map).
   (B)   Scope.
      (1)   To allow use of properties while establishing clear and objective standards to protect and restore water bodies and their associated riparian areas, thereby protecting and restoring the hydrologic, ecological and land conservation functions these areas provide;
      (2)   To protect habitat for fish and other aquatic life, protect habitat for wildlife, protect water quality for human uses and for aquatic life, control erosion and limit sedimentation, limit development in significant riparian corridors and reduce the effects of flooding; and
      (3)   To exclude structures from areas adjacent to fish bearing lakes and streams, and their associated wetlands, and restrict native vegetation removal or other alterations in those areas.
   (C)   Applicability and generalized mapping.
      (1)   (a)   The WRPO Overlay District applies to all wetlands, streams and riparian corridors, identified as significant in the city wetlands and stream corridors map contained in the city’s Comprehensive Plan. This generalized map is based on the city wetlands and riparian inventory. The significant wetlands and riparian corridor map shows the general location of significant resources. However, the edge of the wetlands area cannot be determined, until a wetland delineation is completed by a qualified person.
         (b)   The standards and procedures of this section:
            1.   Apply to all development proposed on a lot or parcel located within, or partially within, the WRPO District;
            2.   Are in addition to the standards of the underlying zone; and
            3.   In cases of conflict, this WRPO District supersedes the standards of the underlying zone.
      (2)   The city wetlands and stream corridors map identifies the significant water resources designated in division (A) above.
      (3)   The applicant shall be responsible for providing a map of the precise location of the top of the streambank, the wetland edge and/or the riparian setback at the time of application submittal.
      (4)   (a)   The inventory of significant wetlands and riparian corridors contained in the Comprehensive Plan identifies all significant wetlands, identifies which streams are fish-bearing and specifies the stream-size category.
         (b)   Based on the classification contained in this inventory, the following significant wetlands and riparian corridor setbacks shall be established:
            1.   a.   Along all streams identified in the Local Riparian/Wetlands Inventory, the riparian corridor boundary shall be 50 feet from the top of bank; and
               b.   This includes the following water bodies:
                  i.   Colby Creek;
                  ii.   Dougherty Slough;
                  iii.   Hall Slough;
                  iv.   Holden Creek;
                  v.   Hoquarton Slough;
                  vi.   Jack Creek;
                  vii.   Trask River; and
                  ix.   Wilson River.
            2.   Along all significant wetlands as designated in the Local Riparian/Wetlands Inventory, the wetlands boundary shall be measured horizontally 50 feet from the line of non-aquatic vegetation.
            3.   Where the riparian corridor includes all or portions of a significant wetland identified in the Local Riparian/Wetlands Inventory, the distance to the riparian corridor boundary shall be measured from the upland edge of the wetland.
            4.   The measurement of distance to the riparian corridor boundary shall be from the top of bank. In areas where the top of the bank cannot be clearly determined, the riparian corridor boundary shall be measured from the ordinary high water level, or the line of non-aquatic vegetation, whichever is most landward.
   (D)   Activities permitted and prohibited within the riparian/wetlands area. This section outlines the uses and conditions associated with development in the WRPO District as required by O.A.R. 660-023-0090(8)(a) through (c).
      (1)   The permanent alteration of the riparian corridor/wetlands area by grading or by the placement of structures or impervious surfaces is prohibited, except for the following uses, provided they are designed to minimize intrusion into the riparian and wetland area, and no other options or locations are feasible:
         (a)   Streets, roads and paths;
         (b)   Drainage facilities, utilities and irrigation pumps;
         (c)   Water-related and water-dependent uses;
         (d)   Replacement of existing structures with structures in the same location that do not disturb additional riparian and wetland surface area;
         (e)   Non-conforming uses existing fully or partially within the riparian corridor and wetland area may be expanded, provided the expansion does not occur within the riparian corridor. Substantial improvement of a non-conforming structure in the riparian corridor/wetland area shall comply with the standards of this chapter;
         (f)   Existing lawn within the riparian corridor/wetland area may be maintained, but not expanded to further intrude into the riparian corridor; and
         (g)   Shoreline stabilization and flood control structures that legally existed on the effective date of this chapter may be maintained. Any expansion of existing structures or development of new structures shall be evaluated by the city and appropriate state natural resource agency staff. Such alteration of the riparian corridor shall be approved only if less invasive or non-structural methods will not adequately meet the stabilization or flood control needs.
      (2)   Removal of riparian/wetland vegetation is prohibited, except for:
         (a)   Removal of non-native vegetation and replacement with native plant species. The replacement vegetation shall cover, at a minimum, the area from which vegetation was removed, and shall maintain or exceed the density of the removed vegetation;
         (b)   Removal of vegetation necessary for the development of approved water-related or water-dependents uses shall be kept to the minimum necessary to allow the water-dependent or water-related use;
         (c)   Trees in danger of falling and thereby posing a hazard to life or property may be felled, following consultation and approval from the Public Works Director. The Public Works Director may require these trees, once felled, to be left in place in the riparian corridor; and
         (d)   Existing landscaping, established prior to the effective date of this chapter may be maintained. However, no new encroachment into the riparian corridor/wetland area shall be allowed. Consultation with the State Department of Fish and Wildlife (ODFW) is required prior to trimming/pruning of riparian/wetland vegetation in order to minimize the adverse effect of the trimming on water quality and aquatic habitat.
      (3)   Exceptions: the following activities are not required to meet the standards of this section:
         (a)   Commercial forest practices regulated by the State Forest Practices Act, being O.R.S. 527.610 et seq.; and
         (b)   Normal and accepted farming practices other than buildings or structures, existing in the riparian area prior to the date of adoption of this chapter.
      (4)   Development proposed within any wetland or stream, in addition to meeting the standards of this section, shall also be approved by Department of State Lands (DSL) and Army Corps of Engineers (CoE);
      (5)   Exemptions:
         (a)   When performed under the direction of the city, and in compliance with the provisions of the city public works improvement standards and specifications, as well as riparian/wetland setbacks in this chapter, the following shall be exempt from the provisions of this chapter:
            1.   Emergency repairs to public facilities; and
            2.   Routine maintenance or replacement of existing facilities.
         (b)   When performed under consultation with ODFW and other authorities as appropriate, the following shall be exempt from the provisions of this chapter:
            1.   Stream and wetlands restoration and enhancement programs, authorized by appropriate permits;
            2.   Non-native vegetation removal; and
            3.   Planting of native plant species.
      (6)   Any permitted crossings of significant riparian corridor/wetland area waterways shall be conducted in consultation with the ODFW, DSL and CoE.
   (E)   Application requirements. All development applications on lots within, or partially within, the WRPO District shall submit the following information, in addition to other information required by this Development Code.
      (1)   Underlying zone district permitted uses. The applicant shall prepare a plan that demonstrates that the use will be constructed and located so as to minimize grading, native vegetation removal and the area necessary for the use. The city may require additional information where necessary to determine WRPO District boundaries or to mitigate identified impacts from a proposed development, including, but not limited to:
         (a)   Site survey as prescribed in applicable zoning clearance permit application;
         (b)   A map showing the name and location of streams including streambanks and significant riparian corridors including adjacent wetlands;
         (c)   A map showing the location of any wetlands; and
         (d)   A map showing the riparian setback area.
      (2)   Underlying zone district conditional uses and land division developments. The applicant shall prepare a required site specific survey. If any conditional use permit or planned unit development activity is proposed within significant water resource site setbacks, the applicant shall provide a survey of the entire site that precisely maps and delineates the following:
         (a)   The location of streams and significant riparian corridors, including adjacent wetlands, and the tops of their respective stream banks or wetland boundaries;
         (b)   Significant wetlands;
         (c)   The area enclosed by the riparian setback;
         (d)   Property lines and easements, existing public rights-of-way, structures, roads and utilities;
         (e)   Vegetation, including trees or tree clusters and under-story vegetation; and
         (f)   Existing and proposed contours at two-foot intervals.
   (F)   Development standards. The following shall apply to all development, including native vegetation removal and excavation, in the WRPO District. No application for uses identified in this section shall be deemed complete until the applicant has addressed each of these standards in writing.
      (1)   Alternatives considered. In general, land development is expected to occur outside the WRPO District significant water resource setback areas. Therefore, development applications must carefully examine upland alternatives for the proposed use and explain the reasons why the proposed development cannot reasonably occur outside of the water resource or riparian/wetland setback area.
      (2)   Minimize siting impacts. The proposed use shall be designed, located and constructed to minimize excavation, loss of native vegetation, erosion and adverse hydrological impacts on significant water resources. Site analysis shall be provided to the city.
         (a)   For land divisions, the applicants must certify that any adverse water quality impacts of the development proposal will be minimized consistent with best management practices.
         (b)   The development shall intrude into water resource or riparian setbacks as little as possible, recognizing the operational needs of the proposed development.
      (3)   Construction materials and methods. Where development within the riparian area is unavoidable, construction materials or methods used within the riparian setback area shall minimize damage to water quality and native vegetation.
      (4)   Alteration requiring mitigation. If a use is proposed within a significant resource site or riparian and wetland setback area, a mitigation plan shall be prepared and implemented.
         (a)   Permanent alteration of the riparian/wetland area by placement of structures or impervious surfaces is allowable under the following procedures, subject to the mitigation requirements of division (E) above.
            1.   Unless permitted under division (D)(1) above, a variance to the riparian/wetland setback approved through the procedures of division (G) below.
            2.   Proposals for development activities within the riparian/wetland area shall be reviewed by ODFW under its fish and wildlife habitat mitigation policy. Mitigation recommendations by ODFW may become conditions for approval of a proposed alteration of a wetland or riparian corridor.
         (b)   Conditional uses in the underlying zoning districts, with the criteria listed in § 152.071, may be approved in the WRPO District where the applicant can demonstrate, through site analysis, that there are no reasonable alternatives and that the proposed use(s) are designed and constructed to minimize intrusion into the significant resource.
      (5)   Erosion and vegetation plan implementation.
         (a)   A schedule of planned erosion control and re-vegetation measures shall be provided, which sets forth the progress of construction activities and mitigating erosion control measures.
         (b)   The approved erosion control or re-vegetation plan shall be implemented and maintained as follows.
            1.   Erosion control measures shall be installed prior to any stripping or excavation work.
            2.   The applicant shall implement the measures and construct facilities contained in the approved erosion control plan in a timely manner. During active construction, the applicant shall inspect erosion control measures daily, and maintain, adjust, repair or replace erosion control measures to ensure that they are functioning properly.
            3.   Eroded sediment shall be removed immediately from pavement surfaces, off-site areas and from the surface water management system, including storm drainage inlets, ditches and culverts.
            4.   Water containing sediment shall not be flushed into the surface water management system, wetlands or streams without first passing through an approved sediment filtering facility or device.
            5.   In addition, prior to fencing placement and excavation, the applicant shall call for inspection. Prior to the foundation inspection for any building, the applicant shall call for inspection to certify that erosion control measures are installed in accordance with the erosion control plan.
   (G)   Variances. In cases where the riparian corridor unduly restricts the development of a lot or parcel legally created before the effective date of this chapter, a property owner may request a variance to the riparian setback. As a replacement to § 152.073, granting of a variance requires findings that:
      (1)   The proposed development represents a reasonable and legal use of the lot or parcel considering the zoning district requirements;
      (2)   Strict adherence to the riparian/wetland area setback and other applicable standards would effectively preclude a use of the parcel that could be reasonably expected to occur in similarly zoned parcels;
      (3)   The property owner would be precluded a substantial property right enjoyed by the majority of landowners in the vicinity and has exhausted all other options available under this chapter to relieve the hardship;
      (4)   The variance is the minimum necessary to retain a use of the property and to afford relief, considering the potential for increased flood and erosion hazard, and potential adverse impacts on native vegetation, fish and wildlife habitat, and water quality;
      (5)   Granting the variance will not be materially detrimental to the public welfare or be injurious to property or improvements in the neighborhood of the premises and no significant adverse impacts on water quality, erosion or slope stability will result from approval of the variance, or these impacts have been mitigated to the greatest extent possible; and
      (6)   The variance will be in general harmony with the intent and purpose of this chapter, and will not adversely affect any officially adopted Comprehensive Plan provision.
   (H)   Mandatory notification of permitting agencies.
      (1)   A riparian corridor and isolated wetlands not designated as significant resources, and wetlands that do not qualify as significant in city local wetland inventory may be subject to permitting requirements of the Department of State Lands and the Army Corps of Engineers. To effectively coordinate permitting responsibilities, the city will notify the Department of State Lands of all development applications that may impact wetland resources in the city. The applicant shall be responsible for obtaining any applicable development permits from state and federal agencies.
      (2)   The notification procedure is as follows.
         (a)   The city shall require written application for all wetland modifications at the time of local permit application.
         (b)   The city shall record the application and forward a copy of the application to the Department of State Lands.
         (c)   The city shall not allow review or approval of any application for permit that includes the intent to modify a wetland or riparian resource until such time as the permitting agencies have approved a modification permit.
         (d)   The city shall report, in writing, a record of modification of the riparian and wetland resources not included on the significant riparian corridor and wetland list to all permitting agencies with a jurisdictional interest.
   (I)   Changes to inventory maps.
      (1)   Claims of an error in the mapped location of a wetland or riparian corridor on the significant wetlands and riparian corridor map may be considered as part of an application for a subdivision, partition, lot line adjustment, site plan review, conditional use permit or variance.
      (2)   Claims that an identified significant wetland or riparian corridor should be deleted from, or added to, the significant wetlands and riparian corridor map shall be considered through the plan amendment process.
      (3)   All claims of map errors shall be supported by adequate inventory information and analysis to justify the claim, and shall be verified by the State Department of State Lands.

§ 152.037 FLOOD HAZARD OVERLAY ZONE (FHO DISTRICT).

   (A)   Purpose. It is the purpose of this section of the Development Code from the city 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 and health;
      (2)   To minimize expenditure of public money and costly flood 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 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.
   (B)   Findings of fact. The flood hazard areas of the city are subject to periodic inundation which results in loss of life and property, health and safety hazards; disruption of commerce and governmental services, extraordinary public expenditures for flood protection and relief; and impairment of the tax base, all of which adversely affect the public health, safety and general welfare.
      (1)   These flood losses are caused by the cumulative effect of obstructions in areas of special flood hazards which increase flood heights and velocities, and when inadequately anchored, damage uses in other areas. Uses that are inadequately floodproofed, elevated or otherwise protected from flood damage also contribute to the flood loss.
      (2)   In order to accomplish its purposes, this chapter includes methods and provisions for:
         (a)   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;
         (b)   Requiring that uses vulnerable to floods, including facilities which serve such uses, be protected against flood damage at the time of initial construction;
         (c)   Controlling the alteration of natural floodplains, stream channels and natural protective barriers, which help accommodate or channel flood waters;
         (d)   Controlling filling, grading, dredging and other development which may increase flood damage; and
         (e)   Preventing or regulating the construction of flood barriers which will unnaturally divert flood waters or may increase flood hazards in other areas.
   (C)   Statutory authorization. The legislature of the state has in O.R.S. Chapter 227 delegated the responsibility to local governmental units to adopt regulations designed to promote the public health, safety and general welfare of its citizenry.
   (D)   Definitions. Unless specifically defined below, words or phrases used in this section shall be interpreted so as to give them the meaning they have in common usage and to give this section its most reasonable application. Many of these definitions also appear in § 152.003. All the definitions listed below apply to this section.
      APPEAL. A request for a review of the City Manager’s interpretation of any provision of this section of the Development Code.
      AREA OF SHALLOW FLOODING. A designated AO, AH, AR/AO, AR/AH or VO Zone on a community’s flood insurance rate map (FIRM) with a 1% or greater annual chance of flooding to an average depth of one to three feet where a clearly defined channel does not exist, where the path of flooding is unpredictable and where velocity flow may be evident. Such flooding is characterized by ponding or sheet flow.
      AREA OF SPECIAL FLOOD HAZARD. The land in the floodplain within a community subject to a 1% or greater chance of flooding in any given year. Designation on maps always includes the letters A or V.
      BASE FLOOD. The flood having a 1% chance of being equaled or exceeded in any given year. Also referred to as the 100-YEAR FLOOD. Designation on maps always includes the letters A or V.
      BASEMENT. Any area of the building having its floor subgrade (below ground level) on all sides.
      BELOW GRADE. Crawlspace means an enclosed area below the base flood elevation in which the interior grade does not exceed two feet below the lowest adjacent exterior grade and the height, measured from the interior grade of the crawlspace to the bottom of the lowest horizontal structural member of the lowest floor does not exceed four feet at any point.
      CRITICAL FACILITY. 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, installations which produce, use or store hazardous materials or hazardous waste.
      DEVELOPMENT. Any human-made 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.
      ELEVATED BUILDING. For insurance purposes, a non-basement building which has its lowest elevated floor raised above ground level by foundation walls, sheer walls, post piers, pilings or columns.
      FLOOD or FLOODING.
         (a)   A general and temporary condition of partial or complete inundation of normally dry land areas from:
            1.   The overflow of inland or tidal waters;
            2.   The unusual and rapid accumulation or runoff of surface waters from any source; and
            3.   Mudslides (i.e., mudflows) which are approximately caused by flooding as defined in this division (D) and are akin to a river of liquid and flowing mud on the surface of normally dry land areas, as when earth is carried by a current of water and deposited along the path of the current.
         (b)   The collapse or subsidence of land along the shore of a lake or other body of water as a result of erosion or undermining caused by waves exceeding anticipated cyclical levels or suddenly caused by an unusually high water level in a natural body of water, accompanied by a severe storm, or by a unanticipated force of nature, such as flash flooding or an abnormal tidal surge, or by some similarly unusually and unforeseeable event which results in flooding as defined in this division (D).
      FLOOD INSURANCE RATE MAP (FIRM). 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.
      FLOOD INSURANCE STUDY. Can also mean flood elevation study, which means an examination, evaluation and determination of flood hazards and, if appropriate, corresponding water surface elevations, or an examination, evaluation and determination of mudslide (i.e., mudflow) and/or flood-related erosion hazards.
      FLOODWAY. The channel of a river or other watercourse and the adjacent land areas that must be reserved in order to discharge the base flood without cumulatively increasing the water surface elevation more than one foot.
      FOUNDATION (PERMANENT). Primary support for a structure through which the imposed load is transmitted to the footing or earth.
      LOWEST FLOOR. 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 non-elevation design requirements of this chapter found in division (G)(2)(a)2. below.
      MANUFACTURED HOME. 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. For insurance purposes, the term MANUFACTURED HOME does not include a “recreational vehicle”.
      MANUFACTURED HOME PARK OR SUBDIVISION. A parcel (or contiguous parcels) of land divided into two or more manufactured home lots for rent or sale.
      NEW CONSTRUCTION. For the purposes of determining insurance rates, structures for which the “start of construction” commenced on or after the effective date of an initial FIRM or after December 31, 1974, whichever is later, and includes any subsequent improvements to such structures. For floodplain management purposes, new construction means structures for which the start of construction commenced on or after the effective date of a floodplain management regulation adopted by a community and includes any subsequent improvements to such structures.
      RECREATIONAL VEHICLE. A vehicle which is:
         (a)   Built on a single chassis;
         (b)   Four hundred square feet or less when measured at the largest horizontal projection;
         (c)   Designed to be self-propelled or permanently towable by a light duty truck; and
         (d)   Designed primarily not for use as a permanent dwelling but as temporary living quarters for recreational, camping, travel or seasonal use.
      START OF CONSTRUCTION. (For other than new construction or substantial improvements under the Coastal Barrier Resources Act (Pub. Law No. 97-348), being 16 U.S.C. §§ 3501 et seq.), includes substantial improvement, and means the date the building permit was issued, provided the actual start of construction, repair, reconstruction, rehabilitation, addition placement or other improvement was within 180 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 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.
      STRUCTURE. A walled and roofed building, a manufactured dwelling, a modular or temporary building or a gas or liquid storage tank that is principally above ground.
      SUBSTANTIAL DAMAGE. Damage of any origin sustained by a structure whereby the cost of restoring the structure to Its before damaged condition would equal or exceed 50% of the market value of the structure before the damage occurred.
      SUBSTANTIAL IMPROVEMENT. Reconstruction, rehabilitation, addition or other improvement of a structure, the cost of which equals or exceeds 50% of the market value of the structure before the “start of construction” of the improvement. This term includes structures which have incurred “substantial damage”, regardless of the actual repair work performed.
         (a)   The market value of the structure is:
            1.   The real market value of the structure prior to the start of the initial repair or improvement; or
            2.   In the case of damage, the real market value of the structure prior to the damage occurring.
         (b)   SUBSTANTIAL IMPROVEMENT does not include either:
            1.   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
            2.   Any alteration of a “historic structure”, provided that the alteration will not preclude the structure’s continued designation as a “historic structure”.
      VARIANCE. A grant of relief from the requirements of this chapter which permits construction in a manner that would otherwise be prohibited by this chapter.
   (E)   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 Tillamook County, Oregon and incorporated areas”, dated September 28, 2018, and as amended with accompanying flood insurance rate maps (FIRM), as subsequently amended by FEMA, are hereby adopted by reference and declared to be a part of this chapter. The flood insurance study is on file at City Hall, 210 Laurel Avenue in Tillamook, Oregon.
      (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. Unless otherwise indicated, non-compliance with the provisions of this chapter (including violations of conditions and safeguards established in connection with conditions) is classified as a violation punishable by a fine set by resolution.
      (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)   In the 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 human-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 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 hereunder.
   (F)   Administration.
      (1)   Establishment of development permit.
         (a)   Development permit required. A development permit, such as the city zoning clearance permit, city flood hazard development permit, the county construction permit, shall be obtained before construction or development begins within any area of special flood hazard established in division (D) above. The permit shall be for all structures including manufactured homes, as set forth in division (D) above, and for all development including fill and other activities, also as set forth in division (D) above.
         (b)   Application for development permit. Application for a development permit shall be made on forms furnished by the City Manager and may include, but not be limited to, plans in duplicate drawn to scale showing the nature, location, dimensions and elevations of the area in question; existing or proposed structures, fill, storage of materials, drainage facilities and the location of the foregoing. Specifically, all of the following information is required:
            1.   Elevation in relation to mean sea level of the lowest floor (including basement) of all 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 division (G)(2)(b); and
            4.   Description of the extent to which a watercourse will be altered or relocated as a result of proposed development.
      (2)   Designation of the local administration. The City Manager is hereby appointed to administer and implement this subchapter by granting or denying development permit applications in accordance with its provisions. The City Manager may delegate to appropriately trained staff.
      (3)   Duties and responsibilities of the City Manager. Duties of the City Manager shall include, but not be limited to:
         (a)   Permit review.
            1.   Review all development permits to determine that the permit requirements of this chapter have been satisfied;
            2.   Review all development permits to determine that all necessary permits have been obtained from those federal, state or local governmental agencies from which prior approval is required; and
            3.   Review all development permits to determine if the proposed development is located in the floodway. If located in the floodway, assure that the encroachment provisions of division (G)(3) below are met.
         (b)   Use of other base flood data. When base flood elevation data has not been provided in accordance with division (E)(2) above, the City Manager may obtain, review and reasonably utilize any base flood elevation and floodway data available from a federal, State or other source, in order to administer divisions (G)(2) and (G)(3) below; and
         (c)   Information to be obtained and maintained.
            1.   Where base flood elevation data is provided through the flood insurance study or required as in division (F)(3)(b) above, obtain and record the actual 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.
            2.   For all new or substantially improved floodproofed structures:
               a.   Verify, record and maintain the actual elevation and elevation certification (in relation to mean sea level); and
               b.   Maintain the floodproofing certifications required in division (G)(2)(b) below.
            3.   Maintain for public inspection all records pertaining to the provisions of this chapter.
            4.   For manufactured homes, maintain the anchoring certifications required in division (G)(1)(a)3. below.
         (d)   Alteration of watercourses.
            1.   Notify adjacent communities and the Department of Land Conservation and Development prior to any alteration or relocation of a watercourse, and submit evidence of such notification to the Federal Insurance Administration.
            2.   Require that maintenance is provided within the altered or relocated portion of said 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 division (F)(4) below.
      (4)   Variance procedure.
         (a)   Appeal Board.
            1.   The City Planning Commission as established by the city shall hear and decide appeals and requests for variances from the requirements of this chapter.
            2.   The City Planning Commission shall hear and decide appeals when it is alleged there is an error in any requirement, decision or determination made by the City Manager in the enforcement or administration of this chapter.
            3.   In reviewing upon such applications, the City Planning Commission 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 flood waters 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 and water systems, and streets and bridges.
            4.   The City Planning Commission may attach such conditions to the granting of variances as it deems necessary to further the purposes of this chapter.
            5.   The city shall maintain the records of all appeal actions and report any variances to the Federal Insurance Administration upon request.
         (b)   Conditions for 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 division (G)(5)(b)1. below has 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; and
               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 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 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.
            7.   Variances may be issued for nonresidential buildings in very limited circumstances to allow a lesser degree of floodproofing than water tight or dry floodproofing, where it can be determined that such action will have low damage potential, complies with all other variance criteria except (F)(4)(b)3., and otherwise complies with divisions (G)(1)(a) and (G)(1)(b) below.
   (G)   Provisions for flood hazard reduction.
      (1)   General standards. In all areas of special flood hazards, the following standards are required.
         (a)   Anchoring.
            1.   All new construction and substantial improvements shall be anchored to prevent flotation, collapse or lateral movement of the structure.
            2.   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).
            3.   A registered architect or engineer shall certify that the anchoring system is in conformance with divisions (G)(1)(a)1. and (G)(1)(a)2. above prior to final inspection.
         (b)   Construction materials and methods.
            1.   All new construction and substantial improvements shall be constructed with materials and utility equipment resistant to flood damage.
            2.   All new construction and substantial improvements shall be constructed using methods and practices that minimize flood damage.
            3.   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.
            4.   An elevation certificate for all new construction and substantial improvements shall be provided to the city for both pre-construction (part 1) and the final lowest floor certification (part 2) by the property owner.
         (c)   Utilities.
            1.   All new and replacement water supply systems shall be designed to minimize or eliminate infiltration of flood waters into the system.
            2.   New and replacement sanitary sewage systems shall be designed to minimize or eliminate infiltration of flood waters into the systems and discharge from the systems into flood waters.
            3.   On-site waste disposal systems shall be located to avoid impairment to them or contamination from them during flooding.
         (d)   Subdivision proposals.
            1.   All subdivision proposals shall be consistent with the need to minimize flood damage.
            2.   All subdivision proposals shall have public utilities and facilities such as sewer, gas, electrical and water systems located and constructed to minimize flood damage.
            3.   All subdivision proposals shall have adequate drainage provided to reduce exposure to flood damage.
            4.   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 or from another authoritative source (division (F)(3)(b) above), applications for building permits shall be reviewed to assure that proposed construction will be reasonably safe from flooding. The test of reasonableness is a local judgment and includes use of historical data, high water marks, photographs of past flooding and the like, where available. Failure to elevate at least two feet above grade in these zones may result in higher insurance rates.
      (2)   Specific standards. In all areas of special flood hazards where base flood elevation data has been provided as set forth in division (E)(2) above or division (F)(3)(b) above, the following provisions are required.
         (a)   Residential construction.
            1.   New construction and substantial improvement of any residential structure shall have the lowest flood, including basement, elevated to two feet above base flood elevation as determined with an elevation certificate; and
            2.   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 exist 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; and
               c.   Openings may be equipped with screens, louvers or other coverings or devices provided that they permit the automatic entry and exit of floodwaters.
         (b)   Nonresidential construction. New construction and substantial improvement of any commercial, industrial or other nonresidential structure shall either have the lowest floor, including basement, elevated to two feet above the base flood elevation as determined with an elevation certificate; or, together with attendant utility and sanitary facilities, shall:
            1.   Be floodproofed so that below the base flood level the structure is water tight with walls substantially impermeable to the passage of water;
            2.   Have structural components capable of resisting hydrostatic and hydrodynamic loads and effects of buoyancy;
            3.   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 division (G)(2)(b)3. 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 division (F)(3)(c)2. above.
            4.   Nonresidential structures that are elevated, not floodproofed, must meet the same standards for space below the lowest floor as described in division (G)(2)(a)2. above.
            5.   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).
         (c)   Manufactured homes.
            1.   All manufactured homes to be placed or substantially improved within Zones A1 through 30, AH and AE shall be elevated on a permanent foundation such that the lowest floor of the manufactured home is two feet above the base flood elevation and be securely anchored to an adequately anchored foundation system in accordance with the provisions of division (G)(1)(a) above.
            2.   All manufactured homes to be placed or substantially improved on sites shall be elevated on a permanent foundation such that the bottom of the longitudinal chassis frame beam shall be at or above the base flood elevation (BFE) and be securely anchored to an adequately designed foundation system to resist floatation, collapse and lateral movement. Electrical crossover connections shall be a minimum of 12 inches above the BFE. Crossover ducts are allowed below the BFE, but shall be constructed to prevent floodwaters from entering or accumulating within system components. This may require an engineer’s certification.
            3.   If the manufactured dwelling is supported on solid foundation walls, the ground area reserved for the placement of a manufactured dwelling shall be a minimum of two feet above BFE unless the foundation walls are designed to automatically equalize hydrostatic forces 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 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; and
               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)   Recreational vehicles. Recreational vehicles may occupy a site in a special flood hazard area for periods of 180 consecutive days or greater providing they are fully licensed and ready for highway use, on its wheels or a jacking system, is attached to the site only by quick disconnect type utilities and security devices and has no permanently attached additions. Recreational vehicles that do not meet these criteria become manufactured homes and must be anchored and elevated pursuant to division (G)(1)(a)2. above.
         (e)   Floodways. Floodways are designated within areas of special flood hazard established in division (E)(2) above. Since the floodway is an extremely hazardous area due to the velocity of flood waters that carry debris, potential projectiles and erosion potential the following provisions apply:
            1.   a.   Prohibit encroachments, including fill, new construction, substantial improvements and other development unless through hydrologic and hydraulic analyses performed in accordance with standard engineering practice by a registered professional civil engineer is provided demonstrating that encroachments shall not result in any increase in flood levels during the occurrence of the base flood discharge.
               b.   The supporting technical data for “no-rise” certification shall be based upon a step-back water analysis and conveyance compensation analysis as required by FEMA and the procedures for “no-rise” certification for proposed developments in the regulatory floodway.
            2.   If division (G)(2)(e)1. above is satisfied, all new construction and substantial improvements shall comply with all applicable flood hazard reduction provision of this division (G).
      (3)   Encroachments. The cumulative effect of any proposed development, when combined with all other existing and anticipated development, shall not increase the water surface elevation of the base flood more than one foot at any point within the flood zone.
      (4)   Zones with base flood elevations but no regulatory floodway.
            1.   In areas within Zones A1 through 30 and AE on the community’s FIRM with a base flood elevation but where no regulatory floodway has been designated, new construction, substantial improvements or other development (including fill) shall be prohibited, 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.
            2.   Applicants of proposed projects that increase the base flood elevation more than one foot shall obtain from FEMA a conditional letter of map revision (CLOMR) before the project may be permitted. As soon as possible, but no later than six months after project completion, an application for a letter of map revision (LOMR) shall be submitted by the applicant to FEMA. The applicant is responsible for paying any costs associated with the CLOMR and LOMR process.
      (5)   Standards for shallow flooding areas (AO Zones).
         (a)   Shallow flooding areas appear on FIRM’S 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.
         (b)   Such flooding is usually characterized as sheet flow. In these areas, the following provisions apply.
            1.   New construction and substantial improvements of residential structures with AO Zones shall have the lowest floor (including basement) elevated above the highest adjacent grade of the building site, to or above the depth number specified on the FIRM (at least two feet if no depth number is specified).
            2.   New construction and substantial improvements of nonresidential structures within AO Zones shall either:
               a.   Have the lowest floor (including basement) elevated above the highest adjacent grade of the building site, to or above the depth number specified on the FIRM (at least two feet if no depth number is specified);
               b.   Together with attendant utility and sanitary facilities, be completely floodproofed to or above that level so that any space below that level is water tight with walls substantially impermeable to the passage of water and with structural components having the capability of resisting hydrostatic and hydrodynamic loads and effects of buoyancy. If this method is used, compliance shall be certified by a registered professional engineer or architect as in division (G)(2)(b)3. above; and
               c.   Require adequate drainage paths around structures on slopes to guide floodwaters around and away from proposed structures.
      (6)   Critical facility. Construction of new critical facilities shall be, to the extent possible, located outside the limits of the special flood hazard area (SFHA) (100-year floodplain). Construction of new critical facilities shall be permissible within the SFHA if no feasible alternative site is available. Critical facility construction within the SFHA shall have the lowest floor elevated three feet above BFE 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 the BFE. 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 BFE shall be provided to all critical facilities to the extent possible.
   (H)   Restrictions.
      (1)   Restrictions. Restrictions regarding height, rear yards, side yards, front yard setbacks, minimum lot area, signs, vision clearance and parking space shall be the same as set forth in each specific zone located within the flood hazard overlay zone area.
      (2)   Prohibited uses. It shall be unlawful to erect, alter, maintain or establish in a flood hazard overlay zone any building, use or occupancy not permitted or allowed in the foregoing provisions, except existing non-conforming uses, which may continue as provided in § 152.073.
   (I)   Requirement to submit new technical data.
      (1)   Within six months of project completion, an applicant who obtains a conditional letter of map revision (CLOMR) from FEMA, or whose development alters a watercourse, modifies floodplain boundaries or base flood elevations shall obtain from FEMA a letter of map revision (LOMR) reflecting the as-built changes to the FIS and/or FIRM.
      (2)   It is the responsibility of the applicant to hove technical data prepared in a format required for a CLOMR or LOMR and to submit such data to FEMA on the appropriate FEMA Form MT-2 application forms. Submittal and processing fees for these map revisions shall be the responsibility of the applicant.
      (3)   Applicants shall be responsible for all costs associated with obtaining a CLOMR or LOMR from FEMA.
      (4)   The Floodplain Administrator shall be under no obligation to sign the community acknowledgment form, which is part of the CLOMR/LOMR application, until the applicant demonstrates that the project will or has met all applicable requirements of this chapter.
