(A) Application review.
(1) The Floodplain Administrator shall review and evaluate the application and shall approve, approve with conditions or deny the application within 60 days of receipt of a correct and complete application.
(2) The Floodplain Administrator shall determine whether the application contains the applicable elements required in these regulations and shall notify the applicant of the Floodplain Administrator’s determination as to completeness within seven working days of receipt.
(3) If the application is found insufficient and if the applicant corrects the identified deficiencies and resubmits the application, the Floodplain Administrator shall notify the applicant whether the resubmitted application contains all the elements required by these regulations, as applicable, within seven working days of receipt of the resubmitted application.

No further action shall be taken on the application by the Floodplain Administrator until the application is resubmitted.
(6) A determination that an application contains the appropriate information for review does not ensure that the floodplain permit application will be approved or conditionally approved and does not limit the ability of the Floodplain Administrator in requesting additional information during the review process.
(B) Notice requirements for floodplain permit applications. Upon receipt of a complete application for a permit, the Floodplain Administrator shall:
(1) Prepare a notice containing the facts pertinent to the application and shall publish the notice at least once in a newspaper of general circulation in the area;
(2) Serve notice by first-class mail upon adjacent property owners, if any;
(3) The State National Flood Insurance Program Coordinator located in DNRC shall also receive notice by the most efficient method. Notice to other stream activity permitting agencies shall also be considered;
(4) The notice shall provide a reasonable period of time, not less than 15 days, for interested parties to submit comments on the proposed activity; and
(5) Prior to any alteration or relocation of a watercourse in the regulated flood hazard area, additionally provide notice to FEMA and adjacent communities.
(C) Permit criteria.
(1) Permits shall be granted or denied on the basis of whether the proposed new construction, substantial improvement or alteration of an artificial obstruction is not a prohibited use and meets the requirements of the minimum standards and criteria in §§ 11-1-75 through 11-1-88 and 11-1-100 through 11-1-103 of this chapter.
(2) The Floodplain Administrator must determine that all necessary permits have been received from those governmental agencies from which approval is required by federal or state law, including § 404 of the Federal Water Pollution Control Act Amendment of 1972, 36 U.S.C. § 1334.
(D) Decision.
(1) The Floodplain Administrator shall approve, conditionally approve or deny the proposed application. The Floodplain Administrator shall notify the applicant of his or her action and the reasons thereof within 60 days of receipt of a correct and complete application unless otherwise specified. A copy of the approved permit must be provided to DNRC.
(2) The granting of a permit does not affect any other type of approval required by any other statute or ordinance of the state, any political subdivision or the United States, but is an added requirement.
(E) Floodplain permit application approval. Upon approval or conditional approval of the floodplain permit application, the Floodplain Administrator shall provide the applicant with a permit including, but not limited to, the following requirements and conditions:
(1) The floodplain permit will become valid when all other necessary permits are in place;
(2) Set forth the time limit of up to one year from the date of permit issuance or as commensurate with the project construction time line for completion of the project or development. The applicant may request an extension for completion for up to an additional year. The request for extension must be made within a reasonable period of the original deadline;
(3) Notify all subsequent property owners and their agents and potential buyers of the floodplain development permit issued on the property and that such property is located within a regulated flood hazard area;
(4) Maintain the artificial obstruction or use to comply with the conditions and specifications of the permit;
(5) Allow the Floodplain Administrator to perform on site inspections at select intervals during construction or completion;
(6) Impose interim reporting to the Floodplain Administrator of construction data to confirm design elevations and other project design criteria, which may be undertaken contemporaneously with any building permit inspections;
(7) Submit a certificate of compliance report and elevation certificate where applicable within 30 days of completion or other time as specified; and
(8) Require FEMA approval of revisions that affected National Flood Insurance Rate Map, in the manner set forth above.

DEVELOPMENT REQUIREMENTS IN THE FLOODWAY
An application for a permit must demonstrate the following goals and criteria are considered and incorporated into the design of any use or artificial obstruction in the floodway requiring a permit.
(A) All projects in the floodway where specifically required herein as requiring an encroachment analysis, must undergo a thorough hydrologic and hydraulic analysis prepared by an engineer to demonstrate their effect on flood flows, velocities and the base flood elevation.
(B) A conditional approval from FEMA of any proposed increase of more than zero (0.00) feet in the base flood elevation must accompany the application. An application for a FEMA conditional letter of map revision approval requires a supporting encroachment analysis.
(C) The maximum allowable increase to the base flood elevation is one-half foot (0.50), unless approval of an alteration of the regulated flood hazard area pursuant to §§ 11-1-45 through 11-1-47 of this chapter occurs with approval of the variance pursuant to §§ 11-1-130 through 11-1-135 of this chapter:
(1) Projects must assure that the carrying capacity of the altered or relocated watercourse is maintained;
(2) Projects must be designed and constructed to ensure that they do not increase the flood hazard on other properties and be reasonably safe from flooding;
(3) The danger to life and property due to backwater or diverted flow caused by the obstruction or use;
(4) The danger that the obstruction or use may be swept downstream to the injury of others;
(5) The availability of alternative locations;
(6) The construction or alteration of the obstruction or use in such manner as to lessen the flooding danger;
(7) The permanence of the obstruction or use;
(8) The anticipated development in the foreseeable future of the area which may be affected by the obstruction or use;
(9) Relevant and related permits for the project have been obtained;
(10) Projects must conform to the additional minimum standards and provisions of this chapter as specified for the use or artificial obstruction specified herein;
(11) Such other factors as are in harmony with the purposes of these regulations, the Montana Floodplain and Floodway Management Act and the accompanying Administrative Rules of Montana; and
(12) The safety of access to property in times of flooding for ordinary and emergency services is subject to other more stringent regulations.

Mining of materials requiring excavation from pits or pools may be permitted; provided that:
(A) A buffer strip of undisturbed land of sufficient width as determined by an engineer to prevent flood flows from channeling into the excavation is left between the edge of the channel and the edge of the excavation;
(B) The excavation meets all applicable laws and regulations of other local and state agencies; and
(C) Excavated material may be processed on site, but is stockpiled outside the floodplain.

Railroad, highway and street stream crossings may be permitted; provided that:
(A) Crossings are designed to offer minimal obstructions to the flood flow;
(B) Where failure or interruption of public transportation facilities would result in danger to public health or safety and where practicable and in consideration of FHWA Federal-Aid Policy Guide, 23 C.F.R. part 650A:
(1) Bridge lower chords shall have freeboard to at least two feet above the base flood elevation to help pass ice flows, the base flood discharge and any debris associated with the discharge; and
(2) Culverts are designed to pass the base flood discharge and maintain at least two feet freeboard on the crossing surface.
(a) If possible, normal overflow channels are preserved to allow passage of sediments to prevent aggradations;
(b) Mid stream supports for bridges, if necessary, have footings buried below the maximum scour depth; and
(c) An encroachment analysis is prepared by an engineer.
