(A) This section applies to proposed development, redevelopment, site modification or building modification within a designated floodway. The designated floodway shall be as delineated on the countywide FIRM of Cook County, as defined in § 151.03. Permits will only be issued for appropriate uses of the designated floodway of which periodic inundation will not pose a danger to the general health and welfare of the user or require the expenditure of public funds or the provisions of public resources or disaster relief services or result in increased flood stages due to the singular or cumulative loss of regulatory floodway storage or regulatory floodway conveyance or increase in flood velocities. All floodway modifications shall be the minimum necessary to accomplish the purpose of the project. The development shall also meet the requirements of § 151.33. No permit from IDNR/OWR or the city shall be required if the project meets Regional Permit No. 3.
(B) No person, firm, corporation or governmental body, shall commence any development in a floodway without first obtaining a development permit from IDNR/OWR, except as noted in division (K) below.

All permitted work shall be completed within local permit expiration period after the date of issuance of the permit or the permit shall expire. Time extensions, of not more than 180 days each, may be granted, in writing, by the building commissioner. Time extensions shall be granted only if the original permit is compliant with this chapter and the FIRM and FIS in effect at the time the extension is granted.
(2) The building commissioner shall be responsible for obtaining from the applicant copies of all other federal, state, and local permits and approvals that may be required for this type of activity.
(3) The building commissioner shall not issue the development permit unless all required federal and state permits have been obtained.
(4) A licensed P.E., under the employ or contract of city shall review and approve applications reviewed under this section.
(E) Preventing increased damages and a list of appropriate uses. The only development in a floodway which will be allowed are appropriate uses, which will not cause a rise in the base flood elevation, and which will not create a damaging or potentially damaging increase in flood heights or velocity or be a threat to public health and safety and welfare or impair the natural hydrologic and hydraulic functions of the floodway or channel, or permanently impair existing water quality or aquatic habitat. Construction impacts shall be minimized by appropriate mitigation methods as called for in this chapter. Only those appropriate uses listed in 17 Ill. Adm. Code Part 3708 will be allowed. Appropriate uses do not include the construction or placement of any new structures, fill, building additions, buildings on stilts, excavation, or channel modifications done to accommodate otherwise non-appropriate uses in the floodway, fencing (including landscaping or planting designed to act as a fence) and storage of materials except as specifically defined as an appropriate use. The approved appropriate uses are as follows:
(1) Flood control structures, dikes, dams, and other public works or private improvements relating to the control of drainage, flooding, erosion, or water quality or habitat for fish and wildlife;
(2) Structures or facilities relating to the use of, or requiring access to, the water or shoreline, such as pumping and treatment facilities, and facilities and improvements related to recreational boating, commercial shipping and other functionally water dependent uses;
(3) Storm and sanitary sewer outfalls;
(4) Underground and overhead utilities;
(5) Recreational facilities such as playing fields and trail systems including any related fencing (at least 50% open when viewed from any one direction) built parallel to the direction of flood flows, and including open air pavilions and toilet facilities (four stall maximum) that will not block flood flow nor reduce floodway storage;
(6) Detached garages, storage sheds, or other non-habitable accessory structures without toilet facilities to existing buildings that will not block flood flows, nor reduce floodway storage;
(7) Bridges, culverts, roadways, sidewalks, railways, runways, and taxiways and any modification thereto;
(8) Parking lots built at or below existing grade where either: the depth of flooding during the base flood will not exceed one foot; or the applicant of a short-term recreational use facility parking lot formally agrees to restrict access during overbank flooding events and accepts liability for all damage caused by vehicular access during all overbank flooding events;
(9) Designated floodway regrading, without fill, to create a positive non-erosive slope toward a watercourse;
(10) Floodproofing activities to protect previously existing lawful structures, including the construction of watertight window wells, elevating structures, or construction of floodwalls around residential, commercial or industrial principal structures where the outside toe of the floodwall shall be no more than ten feet away from the exterior wall of the existing structure, and which are not considered substantial improvements to the structure.
(11) The replacement, reconstruction, or repair of a damaged building, provided that the outside dimensions are not increased, and if the building was damaged to 50% or more of the market value before the damage occurred, the building will be protected from flooding to the FPE.
(12) Modifications to an existing building that would not increase the enclosed floor area of the building below the BFE, and which will not block flood flows including but not limited to, fireplaces, bay windows, decks, patios, and second story additions. If the building is improved to 50% or more of the market value before the modification occurred (i.e., a substantial improvement), the building will be protected from flooding to the FPE.
(13) Appropriate uses do not include the construction or placement of any new buildings, fill, building additions, buildings on stilts, excavation or channel modifications done to accommodate otherwise non-appropriate uses in the floodway, fencing (including landscaping or planting designed to act as a fence) and storage of materials except as specifically defined above as an appropriate use.
(F) Within the designated floodway as identified on the regulatory floodway maps designated by IDNR, the construction of an appropriate use will be considered permissible provided that the proposed project meets the following engineering and mitigation criteria and is so stated in writing with supporting plans, calculations and data by a licensed professional engineer and provided that any structure meets the protection requirements of § 151.10.
(1) Preservation of flood conveyance, so as not to increase flood states upstream. For appropriate uses other than bridge or culvert crossings, on-stream structures or dams, all effective designated floodway conveyance lost due to the project will be replaced for all flood events up to and including the base flood. In calculating effective designated floodway conveyance, the following factors shall be taken into consideration:
(a) Designated floodway conveyance “K” = 1.486AR2/3 I n where “n” is Manning’s roughness factor, “A” is the effective area of the cross-section, and “R” is the ratio of the area to the wetted perimeter. (See Open Channel Hydraulics, Ven Te Chow, 1959, McGraw-Hill Book Company. New York).
(b) The same Manning’s “n” value shall be used for both existing and proposed conditions unless a recorded maintenance agreement with a federal, state, or local unit of government can assure the proposed conditions will be maintained or the land cover is changing from a vegetative to a non-vegetative land cover.
(c) Transition sections shall be provided and used in calculations of effective designated floodway conveyance. The following expansion and contraction ratios shall be used unless an applicant’s engineer can prove to IDNR through engineering calculations or model tests that more abrupt transitions may be used with the same efficiency:
1. When water is flowing from a narrow section to a wider section, the water should be assumed to expand no faster than at a rate of one foot horizontal for every four feet of the flooded stream’s length.
2. When water is flowing from a wide section to a narrow section, the water should be assumed to contract no faster than at a rate of one foot horizontal for every one foot of the flooded stream’s length.
3. When expanding or contracting flows in a vertical direction, a minimum of one foot vertical transition for every ten feet of stream length shall be used.
4. Transition sections shall be provided between cross-sections with rapid expansions and contractions and when meeting the designated floodway delineation on adjacent properties.
5. All cross-sections used in the calculations shall be located perpendicular to the flood flows.
(2) Preservation of floodway storage so as not to increase downstream flooding. Compensatory storage shall be provided for any regulatory floodway storage lost due to the proposed work from the volume of fill or structures placed and the impact of any related flood control projects. Compensatory storage for fill or structures shall be equal to at least the volume of flood plain storage lost. Artificially created storage lost due to a reduction in head loss behind a ridge shall not be required to be replaced.
(3) Designated floodway regrading, without fill, to create a positive non erosive slope toward a watercourse; and the compensatory regulatory floodway storage shall be placed between the proposed normal water elevation and the proposed base flood elevation shall be replaced below the proposed 10% annual chance flood elevation. All regulatory floodway storage lost above the existing 10% annual chance flood elevation shall be replaced above the proposed 10% annual chance flood elevation. All such excavations shall be constructed to drain freely and openly to the watercourse. If the compensatory storage will not be placed at the location of the proposed construction, the applicant’s engineer shall demonstrate to IDNR through a determination of flood discharges and water surface elevations that the compensatory storage is hydraulically equivalent. Finally, there shall be no reduction in floodway surface area as a result of a floodway modification, unless such modification is necessary to reduce flooding at the existing structure.
(4) Preservation of floodway velocities so as not to increase stream erosion or flood heights. For all appropriate uses, except bridges or culverts or on stream structures, the proposed work will not result in an increase in the average channel or regulatory floodway velocities. However, in the case of bridges or culverts or on stream structures built for the purpose of backing up water in the stream during normal or flood flows, velocities may be increased at the structure site if scour, erosion, and sedimentation will be avoided by the use of alternative stabilization measures, soil bio-engineering techniques, nature rock or rip-rap.
(5) Construction of new bridges or culvert crossings and roadway approaches. The proposed structure shall not result in an increase of upstream flood stages greater than one- tenth of a foot when compared to the existing conditions for all flood events up to and including the base flood event; or the upstream flood stage increases will be contained within the channel banks (or within existing vertical extensions of the channel banks) such as within the design protection grade of existing levees or flood walls or within recorded flood easements. If the proposed construction will increase upstream flood stages greater than one-tenth of a foot, the developer must contact IDNR, Dam Safety Section for a dam safety permit or waiver.
(a) The engineering analysis of upstream flood stages must be calculated using the flood study flows, and corresponding flood elevations for tailwater conditions for the flood study specified in § 151.30. Bridges and culverts must be analyzed using any commonly accepted FEMA approved hydraulic models.
(b) Lost floodway storage must be compensated for per § 151.32.
(c) Velocity increases must be mitigated per § 151.32.
(d) If the crossing is proposed over a public water that is used for recreational or commercial navigation, an IDNR permit must be received.
(e) The hydraulic analysis for the backwater caused by the bridge showing the existing condition and proposed regulatory profile must be submitted to IDNR for concurrence that a CLOMR is not required by § 151.32.
(f) All excavations for the construction of the crossing shall be designed per § 151.32.
(6) Reconstruction or modification of existing bridges, culverts, and approach roads.
(a) The bridge or culvert and roadway approach reconstruction or modification shall be constructed with no more than one-tenth foot increase in backwater over the existing flood for all flood frequencies up to and including the base flood event if the existing structure is not a source of flood damage.
(b) If the existing bridge or culvert and roadway approach is a source of flood damage to buildings or structures in the upstream flood plain, the applicant’s engineer shall evaluate the feasibility of redesigning the structure to reduce the existing backwater, taking into consideration the effects on flood stages on upstream and downstream properties.
(c) The determination as to whether or not the existing crossing is a source of flood damage and should be redesigned must be prepared in accordance with the 17 Ill. Adm. Code Part 3708 (Floodway Construction in Northeastern Illinois) and submitted to IDNR for review and concurrence before a permit is issued.
(7) On-stream structures built for the purpose of backing up water. Any increase in upstream flood stages greater than one-tenth foot when compared to the existing conditions, for all flood events up to and including the base flood frequency event shall be contained within the channel banks (or within existing vertical extensions of the channel banks) such as within the design protection grade of existing levees or flood walls or within the recorded flood easements. A permit or letter indicating a permit if not required must be obtained from IDNR, Dam Safety Section from a dam safety permit or waiver for any structure built for the purpose of backing up water in the stream during normal or flood flow. All dams and impoundment structures as defined In § 151.03 shall meet the permitting requirements of 17 Ill. Admin. Code 3702 (Construction and Maintenance of Dams). If the proposed activity invokes a modification of the channel or floodway to accommodate an impoundment, it shall be demonstrated that:
(a) The impoundment is determined to be in the public interest by providing flood control, public recreation, or regional stormwater detention;
(b) The impoundment will not prevent the migration of indigenous fish species, which require access to upstream areas as part of their life cycle, such as for spawning;
(c) The impoundment will not cause or contribute to degraded water quality or habitat conditions. Impoundment design should included gradual bank slopes, appropriate bank stabilization measures, and a pre-sedimentation basin;
(d) A non-point source control plan has been implemented in the upstream watershed to control the effects of sediment runoff as well as minimize the input of nutrients, oil, and grease, metals, and other pollutants. If there is more than one municipality in the upstream watershed, the municipality in which the impoundment is constructed should coordinate with upstream municipalities to ensure comprehensive watershed control; and
(e) The project otherwise complies with the requirements of § 151.32.
(8) Floodproofing of existing habitable, residential, and commercial structures. If construction is required beyond the outside dimensions of the existing building, the outside perimeter of the flood proofing, construction shall be placed no further than ten feet from the outside of the building. Compensation of lost storage and conveyance wilt not be required for floodproofing activities unless they are considered substantial improvements to the structure.
(9) Excavation in the floodway. When excavation is proposed in the design of bridges and culvert openings, including the modifications to and replacement of existing bridge and culvert structures, or to compensate for lost conveyance for other appropriate uses, transition sections shall be provided for the excavation. The following expansion and contraction ratios shall be used unless an applicant’s engineer can prove to IDNR through engineering calculations or model tests that more abrupt transitions may be used with the same efficiency:
(a) When water is flowing from a narrow section to a wider section, the water should be assumed to expand no faster than at a rate of one foot horizontal for every four feet of the flooded stream’s length;
(b) When water is flowing from a wide section to a narrow section, the water should be assumed to contract no faster than at a rate of one foot horizontal for every one foot of the flooded stream’s length; and
(c) When expanding or contracting flows in a vertical direction, a minimum of one foot vertical transition for every ten feet of stream length shall be used.
(d) Erosion/scour protection shall be provided inland upstream and downstream of the transition sections.
(10) Seeding and stabilization plan. For all activities located in a floodway, a seeding and stabilization plan shall be submitted by the applicant.
(11) Public flood control projects. For public flood control projects, the permitting requirements of this section will be considered met if the applicant can demonstrate to IDNR through hydraulic and hydrologic calculations that the proposed project will not singularly or cumulatively result in increased flood heights outside the project right-of-way or easements for all flood events up to and including the base flood frequency event.
(12) General criteria for analysis of flood elevations.
(a) The flood profiles, flows and floodway data in the regulatory floodway study, referenced in § 151,30, must be used for analysis of the base conditions. If the study data appears to be in error or conditions have changed, IDNR shall be contracted for approval and concurrence on the appropriate base conditions data to use.
(b) If the floodway elevation at the site of the proposed construction is affected by backwater from a downstream receiving stream with a larger drainage area, the proposed construction shall be shown to meet the requirements of this section for the base flood frequency flood elevations of the designated floodway conditions and conditions with the receiving stream at normal elevations.
(c) If the applicant learns from the IDNR, local governments, or a private owner that a downstream restrictive bridge or culvert is scheduled to be removed, reconstructed, modified, or a regional flood control project is scheduled to be built, removed, constructed, or modified within the next five years, the proposed construction shall be analyzed and shown to meet the requirements for this section for both the existing conditions and the expected flood profile conditions when the bridge, culvert of flood control project is built.
(13) Conditional letter of map revision. If the appropriate use would result in a change in the regulatory floodway location or the base flood elevation, the applicant shall submit to IDNR and to FEMA all the information, calculations and documents necessary to be issued a conditional regulatory floodway map revision and receive from IDNR a conditional approval of the regulatory floodway change before a permit is issued. However, the final regulatory floodway map will not be changed by
IDNR until as-built plans or record drawings are submitted and accepted by FEMA and IDNR. In the case of non-government projects, the municipality in incorporated areas and the county in unincorporated areas shall concur with the proposed conditional regulatory floodway map revision before IDNR approval can be given. No filling, grading, dredging or excavating shall take place until a conditional approval is issued. No further development activities shall take place until a final letter of map revision (LOMR) is issued by FEMA and IDNR.
(14) Professional engineer’s supervision. All engineering analyses shall be performed by or under the supervision of a licensed professional engineer. All field surveys shall be conducted under the supervision of a licensed professional engineer or licensed land surveyor.
(15) After receipt of conditional approval of the regulatory floodway change and issuance of a permit and a conditional letter of map revision, construction as necessary to change the regulatory floodway designation may proceed but no buildings or structures or other construction that is not an appropriate use may be placed in that area until the regulatory floodway map is changed and a final letter of map revision is received. The regulatory floodway map will be revised upon acceptance and concurrence by IDNR and FEMA of the “as built” plans.
(G) State review. For those projects listed below located in a designated floodway, the following criteria shall be submitted to IDNR for their review and concurrence prior to the issuance of a permit.
(1) IDNR will review an engineer’s analysis of the flood profile due to a proposed bridge pursuant to § 151.32.
(2) IDNR will review an engineer’s determination that an existing bridge or culvert crossing is not a source of flood damage and the analysis indicating the proposed flood profile, pursuant to § 151.32.
(3) The IDNR will review three alternative transition sections and hydraulically equivalent storage pursuant to § 151.32.
(4) The IDNR will review and approve prior to the start of construction any department projects, dams (as defined in § 151.03) and all other state, federal, or local units of government projects, including projects of the municipality or county.
(H) Other permits. In addition to the other requirements of this chapter, a development permit for a site located in a floodway shall not be issued unless the applicant first obtains a permit of written documentation that a permit is not required from IDNR, issued pursuant to ILCS Ch. 615, Act 5, §§ 5 et seq. No permit from IDNR shall be required if the division has delegated this responsibility to the city.
(I) Dam safety permits. Any work involving the construction, modification or removal of a dam as defined in § 151.03 per 17 Ill. Adm. Code Part 3702 (Rules for Construction of Dams) shall obtain an Illinois Division of Water Resources Dam Safety permit prior to the start of construction of a dam. If the building commissioner or city engineer finds a dam that does not have an IDNR permit, the building commissioner or city engineer shall immediately notify the Dam Safety Section of the Division of Water Resources. If the building commissioner or city engineer finds a dam which is believed to be in unsafe condition, the building commissioner or city engineer shall immediately notify the owner of the dam, IDNR, Dam Safety Section in Springfield and the Illinois Emergency Management Agency (IEMA).
(J) Activities that do not require a licensed professional engineer’s review. The following activities may be permitted without a licensed professional engineer's review. Such activities shall still meet the other requirements of this chapter, including the mitigation requirements.
(1) Underground and overhead utilities that:
(a) Do not result in any increase in existing ground elevations; or
(b) Do not require the placement of above ground structures in the floodway; or
(c) In the case of underground stream crossings, the top of the pipe or encasement is buried a minimum of three feet below the existing stream bed; and
(d) In the case of overhead utilities, no supporting towers are placed in the watercourse and are designed in such a fashion as not to catch debris.
(2) Storm and sanitary sewer outfalls that:
(a) Do not extend riverward or lakeward of the existing adjacent natural bank slope;
(b) Do not result in an increase in ground elevation; and
(c) Are designed so as not to cause stream erosion at the outfall location.
(3) Construction of sidewalks, athletic fields (excluding fences), properly anchored playground equipment and patios at grade.
(4) Construction of shoreline and streambank protection that:
(a) Does not exceed 1,000 feet in length;
(b) Materials are not placed higher than the existing top of bank;
(c) Materials are placed so as not to reduce the cross sectional area of the stream channel or bank of the lake; and
(d) Vegetative stabilization and gradual side slopes are the preferred mitigation methods for existing erosion problems. Where high channel velocities, sharp bends or wave action necessitate the use of alternative stabilization measures, natural rock or rip-rap are preferred materials. Artificial materials such as concrete, construction rubble, and gabions should be avoided unless there are no practicable alternatives.
(5) Temporary streams crossings in which:
(a) The approach roads will be one-half foot or less above the natural grade;
(b) The crossing will allow stream flow to pass without backing up the water above the stream bank vegetation line or above any drainage tile or outfall invert;
(c) The top of the roadway fill in the channel will be at least two feet below the top of the lowest bank. Any fill in the channel shall be non-erosive material, such as rip-rap or gravel;
(d) All disturbed stream banks will be seeded or otherwise stabilized as soon as possible upon installation and again upon removal of construction; and
(e) The access road and temporary crossing will be removed within one year after authorization.
