The district allows a wide range of mutually supportive uses in order to enhance Downtown Mandan's role as a commercial, cultural, governmental, health/medical, entertainment, education and residential center. The district standards also facilitate the creation of a strong and distinctive sense of place through the inclusion of open space and public plazas. The use of design standards will maintain the historical integrity, enhance the quality of design, and preserve the human-scale development of downtown.

(c)

Dimensional standards. Development within the DC Downtown Core District is subject to the following dimensional standards:

Sec. 105-4-4. - Floodplain management.

(a)

Statutory authorization, findings of fact, purpose, and objectives.

(1)

Statutory authorization. The Legislature of the State of North Dakota has in North Dakota Century Code, Chapters 40-05, 11-11, and 58-06, delegated responsibility to local governmental units to adopt regulations designed to promote the public health, safety, and general welfare of its citizenry. Therefore, the Board of City Commissioners of the City of Mandan does ordain as follows in this section.

(2)

Findings of fact.

a.

The flood hazard areas of the City of Mandan are subject to periodic inundation which can endanger life, result in loss of property, create health and safety hazards, disrupt commerce and governmental services, cause extraordinary public expenditures for flood protection and relief, and impair the tax base, all of which adversely affect the public health, safety, and general welfare.

b.

Flood losses caused by the cumulative effect of obstructions in the special flood hazard areas cause increases in flood heights and velocities. Inadequately floodproofed, elevated or otherwise unprotected structures also contribute to the flood loss.

(3)

Statement of purpose. It is the purpose of this section to promote the public health, safety, and general welfare, and to minimize public and private losses due to flood conditions in specific areas by provisions designed:

a.

To protect human life and health;

b.

To minimize expenditure of public money for costly flood control projects;

c.

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

d.

To minimize prolonged business interruptions;

e.

To minimize damage to public facilities and utilities such as water and gas mains, electric, telephone and sewer lines, streets, and bridges located in special flood hazard areas;

f.

To help maintain a stable tax base by providing for the second use and development of special flood hazard areas so as to minimize future flood blight areas;

g.

To ensure that potential buyers are notified that property is in a special flood hazard area;

h.

To ensure that those who occupy the special flood hazard areas assume responsibility for their actions.

(4)

Methods of reducing flood losses. In order to accomplish its purposes, this section 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 which may increase flood hazards in other areas.

(b)

(c)

General provisions.

(1)

Lands to which this section applies. This section shall apply to all special flood hazard areas within the jurisdiction of the City of Mandan.

(2)

Basis for establishing the special flood hazard areas. The special flood hazard areas identified by the Federal Emergency Management Agency in a scientific and engineering report entitled "The Flood Insurance Study for the City of Mandan, dated April 19, 2005," with an accompanying Flood Insurance Rate Map is hereby adopted by reference and declared to be a part of this section. The Flood Insurance Study is on file at 205 2nd Avenue Northwest, Mandan, North Dakota.

(3)

Compliance. No structure or land shall hereafter be constructed, located, extended, converted, or altered without full compliance with the terms of this section and other applicable regulations.

(4)

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

(5)

Interpretation. In the interpretation and application of this section, 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 section is considered reasonable for regulatory purposes and is based on scientific and engineering considerations. Larger floods can and will occur on rare occasions. Flood heights may be increased by manmade or natural causes. This section does not imply that land outside the special flood hazard areas or uses permitted within such areas will be free from flooding or flood damages: This section shall not create liability on the part of the City of Mandan, any officer or employee thereof, or the Federal Emergency Management Agency, for any flood damages that result from reliance on this section or any administrative decision lawfully made thereunder.

(7)

Severability. If any section, clause, provision, or portion of this section is adjudged unconstitutional or invalid by a court of law, the remainder of this section shall not be affected and shall remain in full force.

(d)

Administration.

(1)

Establishment of development permit. A development permit shall be obtained before construction or development begins within any special flood hazard area established in section 105-4-4(c)(2). Application for a development permit shall be made on forms furnished by the City of Mandan Floodplain Administrator 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 materials, drainage facilities; and the location of the foregoing. Specifically, the following information is required:

a.

Elevation in the same datum (either NAVD88 or NGVD29) as the FIRM, of the lowest floor of all structures;

b.

Elevation in the same datum (either NAVD88 or NGVD29) as the FIRM to which any structure has been floodproofed;

c.

Certification by a registered professional engineer or architect that the floodproofing methods for any non-residential structure meet the floodproofing criteria in section 105-4-4(e)(2)b.; and,

d.

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

(2)

Designation of the floodplain administrator. The floodplain administrator for the City of Mandan is hereby appointed to administer and implement this section by granting or denying development permit applications in accordance with its provisions.

(3)

Duties and responsibilities of the floodplain administrator. Duties of the floodplain administrator shall include, but not be limited to:

a.

Permit review.

1.

Review all development permits to determine that the permit requirements of this section have been satisfied.

2.

Approve or deny all applications for development permits required by adoption of this section.

3.

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.

4.

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 section 105-4-4(e)(4) are met.

b.

Use of other base flood data. When base flood elevation data has not been provided in accordance with section 105-4-4(c)(2), basis for establishing the special flood hazard areas, the floodplain administrator shall obtain, review, and reasonably utilize any base flood elevation data and floodway data available (known as best available information) from any other federal, state, or other source, as criteria for requiring that new construction, substantial improvements, or other development in the floodplain are administered in accordance with section 105-4-4(e)(2), specific standards.

c.

Information to be obtained and maintained.

1.

Obtain and record the actual elevation (in the same datum (either NAVD88 or NGVD29) as the FIRM), 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:

i.

Obtain and record the actual elevation (in the same datum (either NAVD88 or NGVD29) as the FIRM), to which the structure has been floodproofed;

ii.

Maintain the floodproofing certifications required in section 105-4-4(d)(1)c.

3.

Maintain for public inspection all records pertaining to the provisions of this section.

d.

Alteration of watercourses. The responsible person shall:

1.

Notify nearby communities, water resource districts, and the North Dakota Department of Water Resources, as necessary, prior to any alteration or relocation of a watercourse, and submit evidence of such notification to the Federal Emergency Management Agency.

2.

Require that maintenance is provided within the altered or relocated portion of said watercourse so that the flood carrying capacity is not diminished; and,

3.

Notify the appropriate water resource district prior to removal or placement of fill within 200 feet of the bank of a body of water during normal flow or stage.

e.

Interpretation of flood insurance rate map (FIRM) boundaries. Make interpretation where needed as to the exact location of the boundaries of the special flood hazard areas (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 section 105-4-4(d)(4).

f.

Encroachment analysis. When a regulatory floodway has not been designated, the floodplain administrator must require that no new construction, substantial improvements, or other development (including fill) shall be permitted within Zones A1—-30 and AE on the community's FIRM, unless it is demonstrated that the cumulative effect of the proposed development, when combined with all other existing and anticipated development, will not increase the water surface elevation of the base flood more than one foot at any point within the community.

Under the provisions of 44 CFR Chapter 1, Section 65.12, of the National Flood Insurance Program regulations, a community may approve certain development in Zones A1—A30, AE, AH, on the community's FIRM which increases the water surface elevation of the base flood by more than one foot, provided that the community first applies for and receives a Conditional Letter of Map Revision (CLOMR) through FEMA.

(4)

Variance procedure.

a.

Appeal board.

1.

The board of appeals as established by the City of Mandan shall hear and decide appeals and requests for variances from the requirements of this section.

2.

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

3.

Those aggrieved by the decision of the board of appeals, or any taxpayer, may appeal such decision to the district court, as provided in N.D.C.C. §§ 40-47-11, 11-33-12, or 58-03-14.

4.

In passing upon such applications, the board of appeals shall consider all technical evaluations, all relevant factors, standards specified in other sections of this section; and:

i.

The danger that materials may be swept onto other lands to the injury of others;

ii.

The danger to life and property due to flooding or erosion damage;

iii.

The susceptibility of the proposed facility and its contents to flood damage and the effect of such damage on the individual owner;

iv.

The importance of the services provided by the proposed facility to the community;

v.

The necessity to the facility of a waterfront location, where applicable;

vi.

The availability of alternative locations, for the proposed use which are not subject to flooding or erosion damage;

vii.

The compatibility of the proposed use with existing and anticipated development;

viii.

The relationship of the proposed use to the comprehensive plan and floodplain management program for that area;

ix.

The safety of access to the property in times of flood for ordinary and emergency vehicles;

x.

The expected heights, velocity, duration, rate of rise, and sediment transport of the floodwaters and the effects of wave action, if applicable, expected at the site; and

xi.

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.

5.

Generally, variances may be issued for new construction and substantial improvements to be erected on a lot of one-half acre to less in size contiguous to and surrounded by lots with existing structures constructed below the base flood level, providing items i—xi in section 105-4-4(d)(4)a.4. have been fully considered. As the lot size increases beyond the one-half acre, the technical justification required for issuing the variance increases.

6.

Upon consideration of the factors of section 105-4-4(d)(4)a.4. and the purposes of this section, the board of appeals may attach such conditions to the granting of variances as it deems necessary to further the purposes of this section.

7.

The floodplain administrator shall maintain the records of all appeal actions and to report any variances to the Federal Emergency Management Agency upon request.

b.

Conditions for variances.

1.

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 the remainder of this section.

2.

Variances shall not be issued within the identified floodplain if any increase in flood levels during the base flood discharge would result.

3.

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

4.

Variances shall only be issued upon:

i.

A showing of good and sufficient cause;

ii.

A determination that failure to grant the variance would result in exceptional hardship to the applicant; and,

iii.

A determination that the granting of a variance will not result in increased flood heights, additional threats to public safety, cause fraud on or victimization of the public as identified in section 105-4-4(d)(4)a.4., or conflict with existing local laws or ordinances.

5.

Any applicant to whom a variance is granted shall be given written notice that the structure will be permitted to be built with a lowest floor elevation below the base flood elevation and that the cost of flood insurance will be commensurate with the increased risk resulting from the reduced lowest floor elevation,

(e)

Be fully licensed and highway ready.

(3)

Reserved.

(4)

Floodways. Located within the special flood hazard areas established in section 105-4-4(c)(2) are areas designated as floodways. Since the floodway is an extremely hazardous area due to the velocity of flood waters which carry debris, potential projectiles, and erosion potential, the following provisions apply:

a.

Prohibit encroachments, including fill, new construction, substantial improvements, and other development unless certification by a registered professional engineer or architect is provided demonstrating that encroachments shall not result in any increase in flood levels during the occurrence of the base flood discharge. Any increase, as is used in this section, means any modeled impact greater than 0.00 feet.

b.

If section 105-4-4(e)(4)a. is satisfied, all new construction and substantial improvements shall comply with all applicable flood hazard reduction requirements of this section.

c.

Under the provisions of 44 CFR Section 65.12 of the NFIP Regulations, a community may permit encroachments within the adopted regulatory floodway that would result in an increase in BFEs, provided that the community first applies for and receives a Conditional Letter of Map Revision (CLOMR) through FEMA.

(5)

Enclosures. New construction and substantial improvements, with fully enclosed areas below the lowest floor that are usable solely for parking of vehicles, building access or storage in an area other than a basement and which are subject to flooding shall be designed to automatically equalize hydrostatic flood forces on exterior walls by allowing for the entry and exit of floodwaters.
