These roads should be designed so as to funnel traffic onto U.S. Highway 41 at signalized intersections rather than into residential areas and roads that may adjoin or be near the U.S. 41 district. Bicycle and pedestrian access shall likewise be coordinated with vehicular access, greenbelt design, and parking.
(a) Outside storage of refuse. Unenclosed refuse storage, whether or not in containers, and display of merchandise is prohibited. All refuse shall be contained completely within the principal building or an accessory building. Any accessory building for refuse storage shall be:
(1) Designed to include a roof structure; and
(2) Architecturally compatible with the principal building.
(b) Loading and unloading areas. Loading and unloading berths or bays shall be designed as specified in the underlying primary zoning district(s), except that any loading and unloading berth or bay shall not be oriented towards U.S. 41. Loading and unloading berths or bays oriented toward any other public right of-way, shall be landscaped and screened using masonry walls, plant materials, or a combination thereof, subject to Plan Commission approval.
(c) The development plan shall comply with the thoroughfare plan for the Town and be consistent with approved state highway improvements.
(a) Generally. The purpose of the Route 231 overlay district (hereinafter "Route 231 district") is to promote and protect the public health, safety, comfort, convenience and general welfare by providing consistent and coordinated treatment of the properties bordering Route 231 in the Town. The Route 231 district is intended to serve as a tool for implementing the development policies and guidelines for the Route 231 corridor as set forth in the comprehensive plan. Route 231 is an emerging retail corridor to the Town. The Route 231 corridor is oriented towards neighborhoods serving retail whose viability, quality, and character are important to the community, adjacent residents, employees, business owners, and taxing districts. Further, the Route 231 district is an overlay zone imposed on the current and existing zoning in the designated area. Therefore, it is the further purpose of the Route 231 district to preserve the aesthetic qualities of those bordering properties through:
(1) The promotion of coordinated development in the Route 231 district;
(2) The establishment of high standards for buildings, landscaping, and other improvements constructed on the properties within the Route 231 district which permit innovative site designs and at the same time encourage efficient land usage; and
(3) The establishment of development requirements that will encourage substantial capital investments for the development of those properties and promote the quality, scale and character of development.
(b) Plan Commission approval. The Plan Commission shall approve any new development in the corridor for compliance with the Route 231 district requirements.
(c) Development plan. The Plan Commission shall review the development plan of any proposed use of any lot or parcel of ground within the Route 231 district prior to the issuance of a building permit by the Town pursuant to article XVI.
(d) Application procedure. An applicant shall submit a development plan.
(e) District boundaries. The boundaries of the Route 231 district generally located between U.S. Highway 41 and Cline Avenue and approximately six hundred (600) feet from the Route 231 right-of-way on both sides of Route 231 are established as approved on the zoning map.
(f) Plan Commission review.
(1) The commission must approve, approve with conditions or disapprove the development plan for any tract of land located in the Route 231 district.

All uses that are permitted in the underlying primary zoning district(s), except the uses expressly excluded by section 24-45, are permitted in the Route 231 overlay zone.
Special exceptions are listed in the table in section 24-45.
All accessory uses and buildings that are permitted in the underlying primary zoning district(s) shall be permitted, except that any attached or detached accessory building in any proposed development plan shall have on all sides the same building proportions, architectural features, construction materials, and in general be architecturally compatible with the principal building with which the accessory use or building is associated.
(a) Except as provided in this section, the minimum area for a development plan within the Route 231 district is two (2) acres.
(b) If a parcel of land is located both inside and outside of the Route 231 district, a development plan shall be submitted to the Plan Commission for the entire parcel. Wherever there exists a conflict between the requirements of the underlying zoning and those of the Route 231 district, the requirements for the Route 231 district shall govern and prevail.
(c) If a parcel of land or subdivision lot was recorded prior to the effective date of the ordinance from which this chapter derives, and the parcel or lot does not contain the minimum area required by this section, the undersized parcel or lot ("undersized lot") may be used for any use permitted in the Route 231 district provided that:
(1) The parcel is considered a legal nonconforming use; and
(2) All other requirements applicable to the Route 231 district can be met.
(a) Purpose. The purpose of this section is to provide site design requirements that align buildings along the edges of a parcel, towards the public right-of-way of the Route 231 and where applicable U.S. Highway 41. It is the intent of these regulations to orient new buildings with their longest axis parallel to the adjoining highway or street to create a sense of enclosure along the streets, with parking located to the rear, and, if necessary to the side of a building. Principal buildings that are also located adjacent to any arterial street or parkway shall be sited consistent with the building setback line requirements of the underlying zoning district.
(b) Frontage road set backs and out-lot buildings.

The development plan shall include specific provisions for incorporating pedestrian and bicycle access, circulation, and amenities into the development. Such bicycle and pedestrian access considerations shall include linking pedestrian and bicycle facilities to adjacent development, the overall Route 231 corridor, and the Town overall system of bicycle and pedestrian trails and routes.
Curb cuts and internal site traffic should be designed so as to funnel traffic onto Route 231 at signalized intersections rather than into residential areas and roads that may adjoin or be near this Route 231 district. Bicycle and pedestrian access shall likewise be coordinated with vehicular access, greenbelt design, and parking.
(a) Outside storage of refuse. Unenclosed refuse storage, whether or not in containers, and display of merchandise is prohibited. All refuse shall be contained completely within the principal building or an accessory building. Any accessory building for refuse storage shall be:
(1) Designed to include a roof structure; and
(2) Architecturally compatible with the principal building.
(b) Loading and unloading areas. Loading and unloading berths or bays shall be designed as specified in the underlying primary zoning district(s), except that any loading and unloading berth or bay shall not be oriented towards Route 231. Loading and unloading berths or bays oriented toward any other public right of-way, shall be landscaped and screened using masonry walls, plant materials, or a combination thereof, subject to Plan Commission approval.
(c) Reservation of land for pending state highway improvements. In addition to the development requirements above, a development plan must reserve for acquisition by the State of Indiana all land that the State expects to need for pending improvements to Route 231. An applicant must notify in writing the commissioner of the Indiana Department of Transportation (INDOT) of any proposed development plan that includes land within the projected right-of-way for those pending improvements.
It is the purpose of the floodplain district to apply special regulations to the use of land in those areas of the Town that are subject to predictable inundations of water at frequent intervals. The floodplain district is superimposed over the other established districts.
(a) Permitted uses are listed in the table in section 24-45.

Elevation certificate means a FEMA form that is routinely reviewed and approved by the White House Office of Management and Budget under the Paperwork Reduction Act, that is encouraged to be used to collect certified elevation information.
Enclosed area (enclosure) is an area of a structure enclosed by walls on all sides.
Enclosure below the lowest floor. See "Lowest floor" and "Enclosed area."
Existing manufactured home park or subdivision means a manufactured home park or subdivision for which the construction of facilities for servicing the lots on which the manufactured homes are to be affixed (including, at a minimum, the installation of utilities, the construction of streets, and either final site grading or the pouring of concrete pads) is completed before the effective date of the community's first floodplain ordinance.
Expansion to an existing manufactured home park or subdivision means the preparation of additional sites by the construction of facilities for servicing the lots on which the manufactured homes are to be affixed (including the installation of utilities, the construction of streets, and either final site grading or the pouring of concrete pads).

Fill material includes but is not limited to consolidated material such as concrete and brick and unconsolidated material such as soil, sand, gravel, and stone.
Flood or flooding means a general and temporary condition of partial or complete inundation of normally dry land areas from:
1. The overflow of inland or tidal waters.
2. The unusual and rapid accumulation or runoff of surface waters from any source.
3. Mudslides (i.e., mudflows) which are proximately caused by flooding and are akin to a river of liquid and flowing mud on the surfaces of normally dry land areas, as when earth is carried by a current of water and deposited along the path of the current.
Flood or flooding also includes the collapse or subsidence of land along the shore of a lake or similar body of water as a result of erosion or undermining caused by waves or current of water exceeding anticipated cyclical levels that result in a flood as defined above.
Flood hazard area means areas subject to the one (1) percent annual chance flood. (See "Special flood hazard area.")
Flood Insurance Rate Map (FIRM) means an official map of a community, on which FEMA has delineated both the areas of special flood hazard and the risk premium zones applicable to the community. A FIRM that has been made available digitally is called a Digital Flood Insurance Rate Map (DFIRM).
Flood Insurance Study (FIS) means the official hydraulic and hydrologic report provided by FEMA. The report contains flood profiles, as well as the FIRM and the water surface elevation of the base flood.
Flood prone area means any land area acknowledged by a community as being susceptible to inundation by water from any source. (See "Floodplain.")
Flood protection grade (FPG) is the BFE plus two (2) feet at any given location in the SFHA. (See "Freeboard.")
Floodplain or flood prone area means any land area susceptible to being inundated by water from any source. (See "Flood.")
Floodplain management means the operation of an overall program of corrective and preventive measures for reducing flood damage and preserving and enhancing, where possible, natural resources in the floodplain, including but not limited to emergency preparedness plans, flood control works, floodplain management regulations, and open space plans.
Floodplain management regulations means zoning ordinances, subdivision regulations, building codes, health regulations, special purpose ordinances (such as a floodplain ordinance, grading ordinance and erosion control ordinance), and other applications of police power which control development in flood prone areas. The term describes such state or local regulations in any combination thereof, which provide standards for the purpose of flood damage prevention and reduction.
Floodproofing (dry floodproofing) is a method of protecting a structure that ensures that the structure, together with attendant utilities and sanitary facilities, is watertight to the floodproofed design elevation with walls that are substantially impermeable to the passage of water. All structural components of these walls are capable of resisting hydrostatic and hydrodynamic flood forces, including the effects of buoyancy, and anticipated debris impact forces.
Floodproofing certificate is a form used to certify compliance for nonresidential structures as an alternative to elevating structures to or above the FPG.
Floodway is 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 cumulative increasing the water surface elevation more than a designated height.
Freeboard means a factor of safety, usually expressed in feet above the BFE, which is applied for the purposes of floodplain management. It is used to compensate for the many unknown factors that could contribute to flood heights greater than those calculated for the base flood.
Fringe or flood fringe is the portion of the floodplain lying outside the floodway.
Functionally dependent use means a use which cannot perform its intended purpose unless it is located or carried out in close proximity to water. The term includes only docking facilities, port facilities that are necessary for the loading and unloading of cargo or passengers, and ship building and ship repair facilities, but does not include long-term storage or related manufacturing facilities.
Hardship (as related to variances of this section) means the exceptional hardship that would result from a failure to grant the requested variance. The Town of St. John requires that the variance is exceptional, unusual, and peculiar to the property involved. Mere economic or financial hardship alone is not exceptional. Inconvenience, aesthetic considerations, physical handicaps, personal preferences, or the disapproval of one's neighbors likewise cannot, as a rule, qualify as an exceptional hardship. All of these problems can be resolved through other means without granting a variance, even if the alternative is more expensive, or requires the property owner to build elsewhere or put the parcel to a different use than originally intended.
Highest adjacent grade means the highest natural elevation of the ground surface, prior to the start of construction, next to the proposed walls of a structure.
Historic structure means any structure that is:
1. Listed individually in the National Register of Historic Places (a listing maintained by the Department of the Interior) or preliminarily determined by the Secretary of the Interior as meeting the requirements for individual listing on the National Register;
2. Certified or preliminarily determined by the Secretary of the Interior as contributing to the historical significance of a registered historic district or a district preliminarily determined by the Secretary to qualify as a registered historic district;
3. Individually listed on a state inventory of historic places in states with historic preservation programs which have been approved by the Secretary of the Interior; or
4. Individually listed on a local inventory of historic places in communities with historic preservation programs that have been certified by (a) an approved state program as determined by the Secretary of the Interior, or (b) directly by the Secretary of the Interior in states without approved programs.
Hydrologic and hydraulic engineering analysis means analyses performed by a professional engineer licensed by the State of Indiana, in accordance with standard engineering practices that are accepted by the Indiana Department of Natural Resources and FEMA, used to determine the base flood, other frequency floods, flood elevations, floodway information and boundaries, and flood profiles.
International Code Council-Evaluation Service (ICC-ES) Report means a document that presents the findings, conclusions, and recommendations from a particular evaluation. ICC-ES reports provide information about what code requirements or acceptance criteria were used to evaluate a product, and how the product should be identified, installed.
Letter of final determination (LFD) means a letter issued by FEMA during the mapping update process which establishes final elevations and provides the new flood map and flood study to the community. The LFD initiates the six (6) month adoption period. The community must adopt or amend its floodplain management regulations during this six (6) month period unless the community has previously incorporated an automatic adoption clause.
Letter of map change (LOMC) is a general term used to refer to the several types of revisions and amendments to FEMA maps that can be accomplished by letter. They are broken down into the following categories:
1. Conditional letter of map revision (CLOMR) means FEMA's comment on a proposed project that would, upon construction, result in modification of the SFHA through the placement of fill outside the existing regulatory floodway.
2. Conditional letter of map revision based on fill (CLOMR-F) means a letter from FEMA stating that a proposed structure that will be elevated by fill would not be inundated by the base flood.
3. Letter of map amendment (LOMA) means an amendment by letter to the currently effective FEMA map that establishes that a building or area of land is not located in a SFHA through the submittal of property specific elevation data. A LOMA is only issued by FEMA.
4. Letter of map amendment out as shown (LOMA-OAS) means an official determination by FEMA that states the property or building is correctly shown outside the SFHA as shown on an effective NFIP map. Therefore, the mandatory flood insurance requirement does not apply. An out-as-shown determination does not require elevations.
5. Letter of map revision (LOMR) means an official revision to the currently effective FEMA map. It is issued by FEMA and changes flood zones, delineations, and elevations.
6. Letter of map revision based on fill (LOMR-F) means FEMA's modification of the SFHA shown on the FIRM based on the placement of fill outside the existing regulatory floodway.
Lowest adjacent grade means the lowest elevation, after completion of construction, of the ground, sidewalk, patio, deck support, or basement entryway immediately next to the structure.
Lowest floor means, for floodplain management purposes, the lowest elevation described among the following:
1. The lowest floor of a building.
2. The basement floor.
3. The garage floor if the garage is connected to the building.
4. The first floor of a structure elevated on pilings or pillars.
5. The floor level of any enclosure, other than a basement, below an elevated structure where the walls of the enclosure provide any resistance to the flow of floodwaters. Designs for meeting the flood opening requirement must either be certified by a registered professional engineer or architect or meet or exceed the following criteria:
a. The walls are designed to automatically equalize the hydrostatic flood forces on the walls by allowing for the entry and exit of floodwaters.
b. At least two (2) openings are designed and maintained for the entry and exit of floodwater; and these openings provide a total net area of at least one (1) square inch for every one (1) square foot of enclosed area. The bottom of all such openings shall be no higher than one (1) foot above the exterior grade or the interior grade immediately beneath each opening, whichever is higher. Doorways and windows do not qualify as openings.
6. The first floor of a building elevated on pilings or columns in a coastal high hazard area (as that term is defined in 44 CFR 59.1), as long as it meets the requirements of 44 CFR 60.3.
Manufactured home means a structure, transportable in one (1) or more sections, which is built on a permanent chassis and is designed for use with or without a permanent foundation when attached to the required utilities. The term "manufactured home" does not include a "recreational vehicle."
Manufactured home park or subdivision means a parcel (or contiguous parcels) of land divided into two (2) or more manufactured home lots for rent or sale.
Mitigation means sustained actions taken to reduce or eliminate long-term risk to people and property from hazards and their effects. The purpose of mitigation is twofold: to protect people and structures, and to minimize the cost of disaster response and recovery.
Natural grade for floodplain management purposes means the elevation of the undisturbed natural surface of the ground. Fill placed prior to the date of the initial identification of the flood hazard on a FEMA map is also considered natural grade.
New construction for floodplain management purposes means any structure for which the "start of construction" commenced on or after the effective date of a floodplain management regulations adopted by a community and includes any subsequent improvements to such structures.
New manufactured home park or subdivision means a manufactured home park or subdivision for which the construction of facilities for servicing the lots on which the manufactured homes are to be affixed (including at a minimum, the installation of utilities, the construction of streets, and either final site grading or the pouring of concrete pads) is completed on or after the effective date of the community's first floodplain ordinance.
North American Vertical Datum of 1988 (NAVD 88) as adopted in 1993 is a vertical control datum used as a reference for establishing varying elevations within the floodplain.

One (1) percent annual chance flood is the flood that has a one (1) percent chance of being equaled or exceeded in any given year. See "Regulatory flood."
Physical map revision (PMR) is an official republication of a community's FEMA map to effect changes to base (one (1) percent annual chance) flood elevations, floodplain boundary delineations, regulatory floodways, and planimetric features. These changes typically occur as a result of structural works or improvements, annexations resulting in additional flood hazard areas, or correction to base flood elevations or SFHAs.
Prefabricated building is a building that is manufactured and constructed using prefabrication. It consists of factory-made components or units that are transported and assembled on site to form the complete building.
Principally above ground means that at least fifty-one (51) percent of the actual cash value of the structure, less land value, is above ground.

The actual start means either the first placement of permanent construction of a structure on a site, such as the pouring of a 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, 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 means a walled and roofed building, including a gas or liquid storage tank, which is principally above ground. The term includes a manufactured home, as well as a prefabricated building. It also includes recreational vehicles installed on a site for more than one hundred eighty (180) consecutive days.
Substantial damage means damage of any origin sustained by a structure whereby the cost of restoring the structure to its before damaged condition would equal or exceed fifty (50) percent of the market value of the structure before the damage occurred.
Substantial improvement means any reconstruction, rehabilitation, addition, or other improvement of a structure, the cost of which equals or exceeds fifty (50) percent of the market value of the structure before the "start of construction" of the improvement. This term includes structures that have incurred "repetitive loss" or "substantial damage" regardless of the actual repair work performed. The term does not include improvements of structures to correct existing violations of state or local health, sanitary, or safety code requirements which have been identified by the local code enforcement official and which are the minimum necessary to assure safe living conditions.
Variance is a grant of relief from the requirements of this section consistent with the variance conditions herein.

n. The Floodplain Administrator shall maintain the records of appeal actions and report any variances to the Federal Emergency Management Agency or the Indiana Department of Natural Resources upon request.
(d) Provisions for Flood Hazard Reduction.
(1) Floodplain Status Standards.
a. Floodways (Riverine). Located within SFHAs, established in subsection (b)(2) of this section, are areas designated as floodways. The floodway is an extremely hazardous area due to the velocity of floodwaters, which carry debris, potential projectiles, and has erosion potential. Under the provisions of the Flood Control Act (IC 14-28-1) a permit for construction in a floodway from the Indiana Department of Natural Resources is required prior to the issuance of a local building permit for any excavation, deposit, construction, or obstruction activity located in the floodway. This includes land preparation activities such as filling, grading, clearing, and paving undertaken before the actual start of construction of the structure. General licenses and exemptions to the requirements of the Flood Control Act (IC 14-28-1 and 312 IAC 10) may apply to qualified additions/improvements to existing lawful residential structures, rural bridges, logjam removals, wetland restoration, utility line crossings, outfall projects, creek rock removal, and prospecting.
1. If the site is in a regulatory floodway as established in subsection (b)(2) of this section, the Floodplain Administrator shall require the applicant to forward the application, along with all pertinent plans and specifications, to the Indiana Department of Natural Resources and apply for approval for construction in a floodway, provided the activity does not qualify for a general license or exemption (IC 14-28-1 or 312 IAC 10).
2. No action shall be taken by the Floodplain Administrator until approval has been granted by the Indiana Department of Natural Resources for construction in the floodway, or evidence provided by an applicant that the development meets specified criteria to qualify for a general license or exemption to the requirement of the Flood Control Act. The floodplain development permit shall meet the provisions contained in this section.
3. The floodplain development permit cannot be less restrictive than an approval issued for construction in a floodway issued by the Indiana Department of Natural Resources, or the specified criteria used to qualify for a general license or exemption to the Flood Control Act for a specific site/project.

The U.S. 41 district is intended to serve as a tool for implementing the development policies and guidelines for the U.S. Highway 41 corridor as provided in the comprehensive plan. U.S. Highway 41 is an important retail corridor to the Town and is a premier commercial retail location and employment center whose viability, quality, and character are important to the community, to adjacent residents, to employees, to business owners, and to taxing districts. Further, the U.S. 41 district is an overlay zone imposed on the current and existing zoning in the designated area. Therefore, the purpose of the U.S. 41 district is to preserve the aesthetic qualities of those bordering properties through:
(1) Promotion of coordinated development in the U.S. 41 district;
(2) Establishment of high standards for buildings, landscaping, and other improvements constructed on the properties within the U.S. 41 district which permit innovative site designs and at the same time encourage efficient land usage; and

(1) Context: All buildings shall be designed with respect to the general character of the U.S. 41 district, and particularly with due consideration to buildings located on lots that abut the project site.
(2) The exterior building facade materials shall be composed from the following materials; stone, brick, architectural pre-cast (panels or detailing), architectural metal panels, glass, and ornamental metal. Large expanses of glass are allowed, up to seventy (70) percent of the facade area. Buildings may not be constructed entirely of a metal and glass curtain walls. Concrete block is prohibited as an exterior finish material.
(3) All buildings shall be designed with a minimum of eight (8) external corners in order to eliminate square box buildings.
(4) Building penthouses must be incorporated into the building facade design, including exterior materials specifications.
(5) Sloped roofs shall not exceed one hundred (100) feet without a change in roof plane, gable, or dormer. Sloped roofs shall be either standing seam metal or architectural dimensional shingles.
(6) Exhibits. The following architectural exhibits shall be provided to the Plan Commission in addition to normal submission requirement of the development plan application:
a. A site plan showing the proposed building in the context of adjoining buildings, including buildings across Route 231.
b. Perspective computer-enhanced color renderings showing the proposed building, signage, parking areas (shown loaded) and any displays within the context of the actual existing site conditions, including how the site will look from any adjoining residential areas, as well as from the three (30 other locations specified below, whose distance is no less than three hundred (300) linear feet away nor more than one thousand (1,000) linear feet away (from the property line), along Route 231:
1. Route 231 eastbound lane;
2. Immediately across the highway, from approximately the first floor level; and
3. Route 231 westbound lane.
Public art that is included as part of a development plan shall be displayed in a location that is visually accessible to the public and visible from Route 231.
The development plan shall include specific provisions for incorporating pedestrian and bicycle access, circulation, and amenities into the development. Such bicycle and pedestrian access considerations shall include linking pedestrian and bicycle facilities to adjacent development, the overall Route 231 corridor, and the Town overall system of bicycle and pedestrian trails and routes.
Curb cuts and internal site traffic should be designed so as to funnel traffic onto Route 231 at signalized intersections rather than into residential areas and roads that may adjoin or be near this Route 231 district. Bicycle and pedestrian access shall likewise be coordinated with vehicular access, greenbelt design, and parking.
(a) Outside storage of refuse. Unenclosed refuse storage, whether or not in containers, and display of merchandise is prohibited. All refuse shall be contained completely within the principal building or an accessory building. Any accessory building for refuse storage shall be:
(1) Designed to include a roof structure; and
(2) Architecturally compatible with the principal building.
(b) Loading and unloading areas. Loading and unloading berths or bays shall be designed as specified in the underlying primary zoning district(s), except that any loading and unloading berth or bay shall not be oriented towards Route 231. Loading and unloading berths or bays oriented toward any other public right of-way, shall be landscaped and screened using masonry walls, plant materials, or a combination thereof, subject to Plan Commission approval.
(c) Reservation of land for pending state highway improvements. In addition to the development requirements above, a development plan must reserve for acquisition by the State of Indiana all land that the State expects to need for pending improvements to Route 231. An applicant must notify in writing the commissioner of the Indiana Department of Transportation (INDOT) of any proposed development plan that includes land within the projected right-of-way for those pending improvements.
It is the purpose of the floodplain district to apply special regulations to the use of land in those areas of the Town that are subject to predictable inundations of water at frequent intervals. The floodplain district is superimposed over the other established districts.
(a) Permitted uses are listed in the table in section 24-45.
(b) All land lying within the floodplain of the one-hundred-year frequency flood of Bull Run Ditch, St. John Ditch, and West Creek in St. John are subject to these regulations, in addition to the regulations otherwise established by this article.
(c) When the proposed use is allowable hereunder in any other zoning district, the following uses and types of activities are permitted in the designated floodplain area:
(1) Residential educational and institutional buildings, only if they have a minimum floor elevation of not less than two (2) feet above the one-hundred-year flood level, as established by the state department of natural resources;
(2) Outdoor recreational uses;
(3) Public rights-of-way, private drives, and parking lots;
(4) Commercial buildings in the commercial districts where the minimum floor elevation is not less than two (2) feet above the one-hundred-year flood level; and
(5) Any structure, filling, excavating, or any change in the natural grade of any property requires a permit, and shall not be detrimental to other properties or the characteristics of the floodplain area.
(d) When required by the Town, the applicant shall submit topographic data, engineering studies, or other studies in order for the Town to determine the effects of flooding on a structure or the effects of the structure on the flow of water.
Special exceptions are listed in the table in section 24-45.
Accessory uses and buildings that are permitted in the underlying zoning district shall be permitted.
Bulk requirements shall be the same as the underlying zoning district.
Parking shall comply with the requirements of article XI of this chapter.

Elevation certificate means a FEMA form that is routinely reviewed and approved by the White House Office of Management and Budget under the Paperwork Reduction Act, that is encouraged to be used to collect certified elevation information.
Enclosed area (enclosure) is an area of a structure enclosed by walls on all sides.
Enclosure below the lowest floor. See "Lowest floor" and "Enclosed area."
Existing manufactured home park or subdivision means a manufactured home park or subdivision for which the construction of facilities for servicing the lots on which the manufactured homes are to be affixed (including, at a minimum, the installation of utilities, the construction of streets, and either final site grading or the pouring of concrete pads) is completed before the effective date of the community's first floodplain ordinance.
Expansion to an existing manufactured home park or subdivision means the preparation of additional sites by the construction of facilities for servicing the lots on which the manufactured homes are to be affixed (including the installation of utilities, the construction of streets, and either final site grading or the pouring of concrete pads).

Fill material includes but is not limited to consolidated material such as concrete and brick and unconsolidated material such as soil, sand, gravel, and stone.
Flood or flooding means a general and temporary condition of partial or complete inundation of normally dry land areas from:
1. The overflow of inland or tidal waters.
2. The unusual and rapid accumulation or runoff of surface waters from any source.
3. Mudslides (i.e., mudflows) which are proximately caused by flooding and are akin to a river of liquid and flowing mud on the surfaces of normally dry land areas, as when earth is carried by a current of water and deposited along the path of the current.
Flood or flooding also includes the collapse or subsidence of land along the shore of a lake or similar body of water as a result of erosion or undermining caused by waves or current of water exceeding anticipated cyclical levels that result in a flood as defined above.
Flood hazard area means areas subject to the one (1) percent annual chance flood. (See "Special flood hazard area.")
Flood Insurance Rate Map (FIRM) means an official map of a community, on which FEMA has delineated both the areas of special flood hazard and the risk premium zones applicable to the community. A FIRM that has been made available digitally is called a Digital Flood Insurance Rate Map (DFIRM).
Flood Insurance Study (FIS) means the official hydraulic and hydrologic report provided by FEMA. The report contains flood profiles, as well as the FIRM and the water surface elevation of the base flood.
Flood prone area means any land area acknowledged by a community as being susceptible to inundation by water from any source. (See "Floodplain.")
Flood protection grade (FPG) is the BFE plus two (2) feet at any given location in the SFHA. (See "Freeboard.")
Floodplain or flood prone area means any land area susceptible to being inundated by water from any source. (See "Flood.")
Floodplain management means the operation of an overall program of corrective and preventive measures for reducing flood damage and preserving and enhancing, where possible, natural resources in the floodplain, including but not limited to emergency preparedness plans, flood control works, floodplain management regulations, and open space plans.
Floodplain management regulations means zoning ordinances, subdivision regulations, building codes, health regulations, special purpose ordinances (such as a floodplain ordinance, grading ordinance and erosion control ordinance), and other applications of police power which control development in flood prone areas. The term describes such state or local regulations in any combination thereof, which provide standards for the purpose of flood damage prevention and reduction.
Floodproofing (dry floodproofing) is a method of protecting a structure that ensures that the structure, together with attendant utilities and sanitary facilities, is watertight to the floodproofed design elevation with walls that are substantially impermeable to the passage of water. All structural components of these walls are capable of resisting hydrostatic and hydrodynamic flood forces, including the effects of buoyancy, and anticipated debris impact forces.
Floodproofing certificate is a form used to certify compliance for nonresidential structures as an alternative to elevating structures to or above the FPG.
Floodway is 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 cumulative increasing the water surface elevation more than a designated height.
Freeboard means a factor of safety, usually expressed in feet above the BFE, which is applied for the purposes of floodplain management. It is used to compensate for the many unknown factors that could contribute to flood heights greater than those calculated for the base flood.
Fringe or flood fringe is the portion of the floodplain lying outside the floodway.
Functionally dependent use means a use which cannot perform its intended purpose unless it is located or carried out in close proximity to water. The term includes only docking facilities, port facilities that are necessary for the loading and unloading of cargo or passengers, and ship building and ship repair facilities, but does not include long-term storage or related manufacturing facilities.
Hardship (as related to variances of this section) means the exceptional hardship that would result from a failure to grant the requested variance. The Town of St. John requires that the variance is exceptional, unusual, and peculiar to the property involved. Mere economic or financial hardship alone is not exceptional. Inconvenience, aesthetic considerations, physical handicaps, personal preferences, or the disapproval of one's neighbors likewise cannot, as a rule, qualify as an exceptional hardship. All of these problems can be resolved through other means without granting a variance, even if the alternative is more expensive, or requires the property owner to build elsewhere or put the parcel to a different use than originally intended.
Highest adjacent grade means the highest natural elevation of the ground surface, prior to the start of construction, next to the proposed walls of a structure.
Historic structure means any structure that is:
1. Listed individually in the National Register of Historic Places (a listing maintained by the Department of the Interior) or preliminarily determined by the Secretary of the Interior as meeting the requirements for individual listing on the National Register;
2. Certified or preliminarily determined by the Secretary of the Interior as contributing to the historical significance of a registered historic district or a district preliminarily determined by the Secretary to qualify as a registered historic district;
3. Individually listed on a state inventory of historic places in states with historic preservation programs which have been approved by the Secretary of the Interior; or
4. Individually listed on a local inventory of historic places in communities with historic preservation programs that have been certified by (a) an approved state program as determined by the Secretary of the Interior, or (b) directly by the Secretary of the Interior in states without approved programs.
Hydrologic and hydraulic engineering analysis means analyses performed by a professional engineer licensed by the State of Indiana, in accordance with standard engineering practices that are accepted by the Indiana Department of Natural Resources and FEMA, used to determine the base flood, other frequency floods, flood elevations, floodway information and boundaries, and flood profiles.
International Code Council-Evaluation Service (ICC-ES) Report means a document that presents the findings, conclusions, and recommendations from a particular evaluation. ICC-ES reports provide information about what code requirements or acceptance criteria were used to evaluate a product, and how the product should be identified, installed.
Letter of final determination (LFD) means a letter issued by FEMA during the mapping update process which establishes final elevations and provides the new flood map and flood study to the community. The LFD initiates the six (6) month adoption period. The community must adopt or amend its floodplain management regulations during this six (6) month period unless the community has previously incorporated an automatic adoption clause.
Letter of map change (LOMC) is a general term used to refer to the several types of revisions and amendments to FEMA maps that can be accomplished by letter. They are broken down into the following categories:
1. Conditional letter of map revision (CLOMR) means FEMA's comment on a proposed project that would, upon construction, result in modification of the SFHA through the placement of fill outside the existing regulatory floodway.
2. Conditional letter of map revision based on fill (CLOMR-F) means a letter from FEMA stating that a proposed structure that will be elevated by fill would not be inundated by the base flood.
3. Letter of map amendment (LOMA) means an amendment by letter to the currently effective FEMA map that establishes that a building or area of land is not located in a SFHA through the submittal of property specific elevation data. A LOMA is only issued by FEMA.
4. Letter of map amendment out as shown (LOMA-OAS) means an official determination by FEMA that states the property or building is correctly shown outside the SFHA as shown on an effective NFIP map. Therefore, the mandatory flood insurance requirement does not apply. An out-as-shown determination does not require elevations.
5. Letter of map revision (LOMR) means an official revision to the currently effective FEMA map. It is issued by FEMA and changes flood zones, delineations, and elevations.
6. Letter of map revision based on fill (LOMR-F) means FEMA's modification of the SFHA shown on the FIRM based on the placement of fill outside the existing regulatory floodway.
Lowest adjacent grade means the lowest elevation, after completion of construction, of the ground, sidewalk, patio, deck support, or basement entryway immediately next to the structure.
Lowest floor means, for floodplain management purposes, the lowest elevation described among the following:
1. The lowest floor of a building.
2. The basement floor.
3. The garage floor if the garage is connected to the building.
4. The first floor of a structure elevated on pilings or pillars.
5. The floor level of any enclosure, other than a basement, below an elevated structure where the walls of the enclosure provide any resistance to the flow of floodwaters. Designs for meeting the flood opening requirement must either be certified by a registered professional engineer or architect or meet or exceed the following criteria:
a. The walls are designed to automatically equalize the hydrostatic flood forces on the walls by allowing for the entry and exit of floodwaters.
b. At least two (2) openings are designed and maintained for the entry and exit of floodwater; and these openings provide a total net area of at least one (1) square inch for every one (1) square foot of enclosed area. The bottom of all such openings shall be no higher than one (1) foot above the exterior grade or the interior grade immediately beneath each opening, whichever is higher. Doorways and windows do not qualify as openings.
6. The first floor of a building elevated on pilings or columns in a coastal high hazard area (as that term is defined in 44 CFR 59.1), as long as it meets the requirements of 44 CFR 60.3.
Manufactured home means a structure, transportable in one (1) or more sections, which is built on a permanent chassis and is designed for use with or without a permanent foundation when attached to the required utilities. The term "manufactured home" does not include a "recreational vehicle."
Manufactured home park or subdivision means a parcel (or contiguous parcels) of land divided into two (2) or more manufactured home lots for rent or sale.
Mitigation means sustained actions taken to reduce or eliminate long-term risk to people and property from hazards and their effects. The purpose of mitigation is twofold: to protect people and structures, and to minimize the cost of disaster response and recovery.
Natural grade for floodplain management purposes means the elevation of the undisturbed natural surface of the ground. Fill placed prior to the date of the initial identification of the flood hazard on a FEMA map is also considered natural grade.
New construction for floodplain management purposes means any structure for which the "start of construction" commenced on or after the effective date of a floodplain management regulations adopted by a community and includes any subsequent improvements to such structures.
New manufactured home park or subdivision means a manufactured home park or subdivision for which the construction of facilities for servicing the lots on which the manufactured homes are to be affixed (including at a minimum, the installation of utilities, the construction of streets, and either final site grading or the pouring of concrete pads) is completed on or after the effective date of the community's first floodplain ordinance.
North American Vertical Datum of 1988 (NAVD 88) as adopted in 1993 is a vertical control datum used as a reference for establishing varying elevations within the floodplain.
Obstruction includes, but is not limited to, any dam, wall, wharf, embankment, levee, dike, pile, abutment, protection, excavation, canalization, bridge, conduit, culvert, building, wire, fence, rock, gravel, refuse, fill, structure, vegetation, or other material in, along, across or projecting into any watercourse which may alter, impede, retard or change the direction and/or velocity of the flow of water; or due to its location, its propensity to snare or collect debris carried by the flow of water, or its likelihood of being carried downstream.
One (1) percent annual chance flood is the flood that has a one (1) percent chance of being equaled or exceeded in any given year. See "Regulatory flood."
Physical map revision (PMR) is an official republication of a community's FEMA map to effect changes to base (one (1) percent annual chance) flood elevations, floodplain boundary delineations, regulatory floodways, and planimetric features. These changes typically occur as a result of structural works or improvements, annexations resulting in additional flood hazard areas, or correction to base flood elevations or SFHAs.
Prefabricated building is a building that is manufactured and constructed using prefabrication. It consists of factory-made components or units that are transported and assembled on site to form the complete building.
Principally above ground means that at least fifty-one (51) percent of the actual cash value of the structure, less land value, is above ground.
Recreational vehicle means a vehicle which is:
1. Built on a single chassis;
2. Four hundred (400) square feet or less when measured at the largest horizontal projections;
3. Designed to be self-propelled or permanently towable by a light duty truck; and
4. Designed primarily not for use as a permanent dwelling, but as temporary living quarters for recreational camping, travel, or seasonal use.
Regulatory flood means the flood having a one (1) percent chance of being equaled or exceeded in any given year, as calculated by a method and procedure that is acceptable to and approved by the Indiana Department of Natural Resources and the Federal Emergency Management Agency. The regulatory flood elevation at any location is as defined in subsection (b)(2) of this section. The "regulatory flood" is also known by the term "base flood," "one (1) percent annual chance flood," and "one hundred (100) year flood."
Repetitive loss means flood-related damages sustained by a structure on two (2) separate occasions during a ten (10) year period for which the cost of repairs at the time of each such flood event, on the average, equaled or exceeded twenty-five (25) percent of the market value of the structure before the damage occurred.
Riverine means relating to, formed by, or resembling a river (including tributaries), stream, brook, etc.

Special flood hazard area (SFHA), synonymous with "areas of special flood hazard" and floodplain, means those lands within the jurisdiction of the Town of St. John subject to a one (1) percent or greater chance of flooding in any given year. Special flood hazard areas are designated by the Federal Emergency Management Agency on Flood Insurance Rate Maps, Flood Insurance Studies, flood boundary and floodway maps and flood hazard boundary maps as Zones A, AE, AH, AO, A1-30, A99, or VE. The SFHA includes areas that are flood prone and designated from other federal, state or local sources of data, including but not limited to best available flood layer maps provided by or approved by the Indiana Department of Natural Resources, historical flood information reflecting high water marks, previous flood inundation areas, and flood prone soils associated with a watercourse.
Start of construction includes substantial improvement, and means the date the building permit was issued, provided the actual start of construction, repair, reconstruction, or improvement was within one hundred eighty (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 a 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, 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 means a walled and roofed building, including a gas or liquid storage tank, which is principally above ground. The term includes a manufactured home, as well as a prefabricated building. It also includes recreational vehicles installed on a site for more than one hundred eighty (180) consecutive days.
Substantial damage means damage of any origin sustained by a structure whereby the cost of restoring the structure to its before damaged condition would equal or exceed fifty (50) percent of the market value of the structure before the damage occurred.
Substantial improvement means any reconstruction, rehabilitation, addition, or other improvement of a structure, the cost of which equals or exceeds fifty (50) percent of the market value of the structure before the "start of construction" of the improvement. This term includes structures that have incurred "repetitive loss" or "substantial damage" regardless of the actual repair work performed. The term does not include improvements of structures to correct existing violations of state or local health, sanitary, or safety code requirements which have been identified by the local code enforcement official and which are the minimum necessary to assure safe living conditions.
Variance is a grant of relief from the requirements of this section consistent with the variance conditions herein.
Violation means the failure of a structure or other development to be fully compliant with this section.
Walled and roofed means a building that has two (2) or more exterior rigid walls and a fully secured roof and is affixed to a permanent site.

Should the floodway limits not be delineated on the Flood Insurance Rate Map for a studied SFHA designated as an "AE Zone," the limits of the floodway will be according to the best available flood layer as provided by the Indiana Department of Natural Resources.
b. The regulatory flood elevation for each studied SFHA within the jurisdiction of the Town of St. John, delineated as an "AH Zone" on the Lake County, Indiana, and Incorporated Areas Flood Insurance Rate Map dated January 18, 2012, shall be that elevation published on the Lake County, Indiana, and Incorporated Areas Flood Insurance Rate Map dated January 18, 2012, as well as any subsequent updates, amendments, or revisions prepared by the Federal Emergency Management Agency with the most recent date.
c. The regulatory flood elevation, floodway, and fringe limits for each of the SFHAs within the jurisdiction of the Town of St. John, delineated as an "A Zone" on the Lake County, Indiana, and Incorporated Areas Flood Insurance Rate Map, dated January 18, 2012, as well as any subsequent updates, amendments, or revisions, prepared by the Federal Emergency Management Agency with the most recent date, shall be according to the best available flood layer provided by the Indiana Department of Natural Resources, provided the upstream drainage area from the subject site is greater than one (1) square mile. Whenever a party disagrees with the best available flood layer data, the party needs to replace existing data with better data that meets current engineering standards. To be considered, this data must be submitted to the Indiana Department of Natural Resources for review and subsequently approved..
d. In the absence of a published FEMA map, or absence of identification on a FEMA map, the regulatory flood elevation, floodway, and fringe limits of any watercourse in the community's known flood prone areas shall be according to the best available flood layer as provided by the Indiana Department of Natural Resources, provided the upstream drainage area from the subject site is greater than one (1) square mile.
e. Upon issuance of a letter of final determination (LFD), any more restrictive data in the new (not yet effective) mapping/study shall be utilized for permitting and construction (development) purposes, replacing all previously effective less restrictive flood hazard data provided by FEMA.
(3) Establishment of Floodplain Development Permit. A floodplain development permit shall be required in conformance with the provisions of this section prior to the commencement of any development activities in areas of special flood hazard.
(4) Compliance.
a. No structure shall hereafter be located, extended, converted, or structurally altered within the SFHA without full compliance with the terms of this section and other applicable regulations.
b. Where an existing or proposed structure or other development is affected by multiple flood zones, by multiple base flood elevations, or both, the development activity must comply with the provisions of this section applicable to the most restrictive flood zone and the most conservative (highest) base flood elevation affecting any part of the existing or proposed structure; or for other developments, affecting any part of the area of the development.
c. No land or stream within the SFHA shall hereafter be altered without full compliance with the terms of this section and other applicable regulations.
(5) Abrogation and Greater Restrictions. This section is not intended to repeal, abrogate, or impair any existing easements, covenants, or deed restrictions. However, where this section and another conflict or overlap, whichever imposes the more stringent restrictions shall prevail.
(6) Discrepancy Between Mapped Floodplain and Actual Ground Elevations.
a. In cases where there is a discrepancy between the mapped floodplain (SFHA) with base flood elevations provided (riverine or lacustrine Zone AE or Zone AH) on the FIRM and the actual ground elevations, the elevation provided on the profiles or table of still water elevations shall govern.
b. If the elevation of the site in question is below the base flood elevation, that site shall be included in the SFHA and regulated accordingly.
c. If the natural grade elevation of the site in question is at or above the base flood elevation and a LOMA or LOMR-FW is obtained, the floodplain regulations will not be applied provided the LOMA or LOMR-FW is not subsequently superseded or invalidated.
(7) Interpretation. In the interpretation and application of this section all provisions shall be:
a. Considered as minimum requirements.
b. Liberally construed in favor of the governing body.
c. Deemed neither to limit nor repeal any other powers granted under state statutes.
(8) Warning and Disclaimer of Liability. The degree of flood protection required by this section is considered reasonable for regulatory purposes and is based on available information derived from engineering and scientific methods of study. Larger floods can and will occur on rare occasions. Therefore, this section does not create any liability on the part of the Town of St. John, the Indiana Department of Natural Resources, or the State of Indiana, for any flood damage that results from reliance on this section, or any administrative decision made lawfully thereunder.
(9) Penalties for Violation. Failure to obtain a floodplain development permit in the SFHA or failure to comply with the requirements of a floodplain development permit or conditions of a variance shall be deemed to be a violation of this section. All violations shall be considered a common nuisance and be treated as such in accordance with the provisions of the zoning code for the Town of St. John. A separate offense shall be deemed to occur for each day the violation continues to exist.
a. The Town Manager or the Town Building and Planning Director for the Town of St. John shall inform the owner that any such violation is considered a willful act to increase flood damages and therefore may cause coverage by a standard flood insurance policy to be suspended.
b. Nothing herein shall prevent the Town of St. John from taking such other lawful action to prevent or remedy any violations. All costs connected therewith shall accrue to the person or persons responsible.

n. The Floodplain Administrator shall maintain the records of appeal actions and report any variances to the Federal Emergency Management Agency or the Indiana Department of Natural Resources upon request.
(d) Provisions for Flood Hazard Reduction.
(1) Floodplain Status Standards.
a. Floodways (Riverine). Located within SFHAs, established in subsection (b)(2) of this section, are areas designated as floodways. The floodway is an extremely hazardous area due to the velocity of floodwaters, which carry debris, potential projectiles, and has erosion potential. Under the provisions of the Flood Control Act (IC 14-28-1) a permit for construction in a floodway from the Indiana Department of Natural Resources is required prior to the issuance of a local building permit for any excavation, deposit, construction, or obstruction activity located in the floodway. This includes land preparation activities such as filling, grading, clearing, and paving undertaken before the actual start of construction of the structure. General licenses and exemptions to the requirements of the Flood Control Act (IC 14-28-1 and 312 IAC 10) may apply to qualified additions/improvements to existing lawful residential structures, rural bridges, logjam removals, wetland restoration, utility line crossings, outfall projects, creek rock removal, and prospecting.
1. If the site is in a regulatory floodway as established in subsection (b)(2) of this section, the Floodplain Administrator shall require the applicant to forward the application, along with all pertinent plans and specifications, to the Indiana Department of Natural Resources and apply for approval for construction in a floodway, provided the activity does not qualify for a general license or exemption (IC 14-28-1 or 312 IAC 10).
2. No action shall be taken by the Floodplain Administrator until approval has been granted by the Indiana Department of Natural Resources for construction in the floodway, or evidence provided by an applicant that the development meets specified criteria to qualify for a general license or exemption to the requirement of the Flood Control Act. The floodplain development permit shall meet the provisions contained in this section.
3. The floodplain development permit cannot be less restrictive than an approval issued for construction in a floodway issued by the Indiana Department of Natural Resources, or the specified criteria used to qualify for a general license or exemption to the Flood Control Act for a specific site/project. However, a community's more restrictive regulations (if any) shall take precedence.
4. In floodway areas identified on the FIRM, development shall cause no increase in flood levels during the occurrence of the base flood discharge without first obtaining a conditional letter of map revision and meeting requirements of subsection (c)(5)a. of this section. A conditional letter of map revision cannot be issued for development that would cause an increase in flood levels affecting a structure and such development should not be permitted.
5. In floodway areas identified by the Indiana Department of Natural Resources through detailed or approximate studies but not yet identified on the effective FIRM as floodway areas, the total cumulative effect of the proposed development, when combined with all other existing and anticipated development, shall not adversely affect the efficiency, or unduly restrict the capacity, of the floodway. This adverse effect is defined as an increase in the elevation of the regulatory flood of at least fifteen hundredths (0.15) of a foot as determined by comparing the regulatory flood elevation under the project condition to that under the natural or pre-floodway condition as proven with hydraulic analyses.
6. For all projects involving channel modifications or fill (including levees) the Town of St. John shall submit the data and request that the Federal Emergency Management Agency revise the regulatory flood data per mapping standard regulations found at 44 CFR 65.12.
b. Fringe (Riverine). If the site is in the fringe (either identified on the FIRM or identified by the Indiana Department of Natural Resources through detailed or approximate studies and not identified on a FIRM), the Floodplain Administrator may issue the local floodplain development permit provided the provisions contained in this subsection (d) have been met.
c. SFHAs Without Established Base Flood Elevation and/or Floodways/Fringes (Riverine).
1. Drainage area upstream of the site is greater than one (1) square mile:
If the site is in an identified floodplain where the limits of the floodway and fringe have not yet been determined, and the drainage area upstream of the site is greater than one (1) square mile, the Floodplain Administrator shall require the applicant to forward the application, along with all pertinent plans and specifications, to the Indiana Department of Natural Resources for review and comment.
No action shall be taken by the Floodplain Administrator until written approval from the Indiana Department of Natural Resources (approval for construction in a floodway, letter of authorization, or evidence of general license qualification) or a floodplain analysis/regulatory assessment citing the one (1) percent annual chance flood elevation and the recommended Flood Protection Grade has been received from the Indiana Department of Natural Resources.
Once the Floodplain Administrator has received the proper written approval, evidence of general license qualification, or floodplain analysis/regulatory assessment approving the proposed development from the Indiana Department of Natural Resources, a floodplain development permit may be issued, provided the conditions of the floodplain development permit are not less restrictive than the conditions received from the Indiana Department of Natural Resources and the provisions contained in this section have been met.
2. Drainage area upstream of the site is less than one (1) square mile:
If the site is in an identified floodplain where the limits of the floodway and fringe have not yet been determined and the drainage area upstream of the site is less than one (1) square mile, the Floodplain Administrator shall require the applicant to provide an engineering analysis showing the limits of the floodplain and one (1) percent annual chance flood elevation for the site.
Upon receipt, the Floodplain Administrator may issue the local floodplain development permit, provided the provisions contained in this subsection (d) have been met.
d. SFHAs Not Identified on a Map.
1. If a proposed development site is near a waterway with no SFHA identified on a map, the Floodplain Administrator shall verify the drainage area upstream of the site. If the drainage area upstream of the site is verified as being greater than one (1) square mile, the Floodplain Administrator shall require the applicant to forward the application, along with all pertinent plans and specifications, to the Indiana Department of Natural Resources for review and comment.
2. No action shall be taken by the Floodplain Administrator until written approval from the Indiana Department of Natural Resources (approval for construction in a floodway, letter of authorization, or evidence of general license qualification) or a floodplain analysis/regulatory assessment citing the one (1) percent annual chance flood elevation and the recommended flood protection grade has been received from the Indiana Department of Natural Resources.
3. Once the Floodplain Administrator has received the proper written approval, evidence of general license qualification, or floodplain analysis/regulatory assessment approving the proposed development from the Indiana Department of Natural Resources, a floodplain development permit may be issued, provided the conditions of the floodplain development permit are not less restrictive than the conditions received from the Indiana Department of Natural Resources and the provisions contained in this subsection (d) have been met.
(2) General Standards. In all areas of special flood hazard, the following provisions are required:
a. All new construction, reconstruction or repairs made to a repetitive loss structure, and substantial improvements shall be anchored to prevent flotation, collapse or lateral movement of the structure.
b. New construction and substantial improvements shall be constructed with materials and utility equipment resistant to flood damage below the FPG.
c. New construction and substantial improvements must incorporate methods and practices that minimize flood damage.
