Code of Ordinances

of Union County, Illinois.

Ordinance Chapter: Chapter 14 - Flood Plain Code [14-1]

This Code repeals and replaces oth­er ordi­nances adopt­ed by the Coun­ty Board of Com­mis­sion­ers to ful­fill the require­ments of the Nation­al Flood Insur­ance Pro­gram includ­ing: 2006 Ordi­nance Reg­u­lat­ing Devel­op­ment with­in Flood­plain Areas.  How­ev­er, this Code does not repeal the orig­i­nal res­o­lu­tion or ordi­nance adopt­ed to achieve eli­gi­bil­i­ty in the pro­gram.  Nor does this Code repeal, abro­gate, or impair any exist­ing ease­ments, covenants, or deed restric­tions.  Where this Code and oth­er ordi­nance ease­ments, covenants, or deed restric­tions con­flict or over­lap, whichev­er impos­es the more strin­gent restric­tions shall pre­vail.

(Ord.  No. 08–03; 05–05–08)

Fail­ure to obtain a per­mit for devel­op­ment in the flood­plain or fail­ure to com­ply with the con­di­tions of a per­mit or a vari­ance shall be deemed to be a vio­la­tion of this Code.  Upon due inves­ti­ga­tion, the Coun­ty Super­in­ten­dent of High­ways may deter­mine that a vio­la­tion of the min­i­mum stan­dards of this Code exists.  The Coun­ty Super­in­ten­dent of High­ways shall noti­fy the own­er in writ­ing of such vio­la­tion.

(A) If such own­er fails after ten (10) days notice to cor­rect the vio­la­tion:

  1. The Coun­ty Super­in­ten­dent of High­ways shall request the Union Coun­ty State’s Attor­ney to make appli­ca­tion to the cir­cuit court for an injunc­tion requir­ing con­for­mance with this Code or make such oth­er order as the court deems nec­es­sary to secure com­pli­ance with the Code.
  2. Any per­son who vio­lates this Code shall upon con­vic­tion there­of be fined not less than Fifty Dol­lars ($50.00) or more than Sev­en Hun­dred Fifty Dol­lars ($750.00) for each offense.
  3. A sep­a­rate offense shall be deemed com­mit­ted upon each day dur­ing or on which a vio­la­tion occurs or con­tin­ues.
  4. The Coun­ty Super­in­ten­dent of High­ways shall record a notice of vio­la­tion on the title of the prop­er­ty.

(B) The Coun­ty Super­in­ten­dent of High­ways 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.

The Coun­ty Super­in­ten­dent of High­ways is autho­rized to issue an order requir­ing the sus­pen­sion of the sub­ject devel­op­ment.  The stop-work order shall be in writ­ing, indi­cate the rea­son for the issuance, and shall order the action, if nec­es­sary, to resolve the cir­cum­stances requir­ing the stop-work order.  The stop-work order con­sti­tutes a sus­pen­sion of the per­mit.

No site devel­op­ment per­mit shall be per­ma­nent­ly sus­pend­ed or revoked until a hear­ing is held by the Coun­ty Board of Com­mis­sion­ers.  Writ­ten notice of such hear­ing shall be served on the per­mit­tee and shall state:

  1. The grounds for the com­plaint, rea­sons for sus­pen­sion or revo­ca­tion, and
  2. the time and place of the hear­ing.

At such hear­ing the per­mit­tee shall be giv­en an oppor­tu­ni­ty to present evi­dence on their behalf.  At the con­clu­sion of the hear­ing, the Coun­ty Board of Com­mis­sion­ers shall deter­mine whether the per­mit shall be sus­pend­ed or revoked.

(C) Noth­ing here­in shall pre­vent Union Coun­ty from tak­ing such oth­er law­ful action to pre­vent or rem­e­dy any vio­la­tions.  All costs con­nect­ed there­with shall accrue to the per­son or per­sons respon­si­ble.

The degree of pro­tec­tion required by this Code is con­sid­ered rea­son­able for reg­u­la­to­ry pur­pos­es and is based on avail­able infor­ma­tion derived from engi­neer­ing and sci­en­tif­ic meth­ods of study.  Larg­er floods may occur or flood heights may be increased by man-made or nat­ur­al caus­es.  This Code does not imply that devel­op­ment either inside or out­side of the flood­plain will be free from flood­ing or dam­age.  This Code does not cre­ate lia­bil­i­ty on the part of Union Coun­ty or any offi­cer or employ­ee there­of for any flood dam­age that results from prop­er reliance on this Code or any admin­is­tra­tive deci­sion made law­ful­ly there under.

When­ev­er the stan­dards of this Code place undue hard­ship on a spe­cif­ic devel­op­ment pro­pos­al, the appli­cant may apply to the Coun­ty Board of Com­mis­sion­ers for a vari­ance.  The Coun­ty Board of Com­mis­sion­ers shall review the applicant’s request for a vari­ance and shall sub­mit its rec­om­men­da­tion to the Coun­ty Board of Com­mis­sion­ers.  The Coun­ty Board of Com­mis­sion­ers may attach such con­di­tions to grant­i­ng of a vari­ance as it deems nec­es­sary to fur­ther the intent of this Code.

(A) No vari­ance shall be grant­ed unless the appli­cant demon­strates that all of the fol­low­ing con­di­tions are met:

  1. The devel­op­ment activ­i­ty can­not be locat­ed out­side the flood­plain.
  2. An excep­tion­al hard­ship would result if the vari­ance were not grant­ed.
  3. The relief request­ed is the min­i­mum nec­es­sary.
  4. There will be no addi­tion­al threat to pub­lic health, safe­ty or cre­ation of a nui­sance.
  5. There will be no addi­tion­al pub­lic expense for flood pro­tec­tion, res­cue or relief oper­a­tions, polic­ing, or repairs to roads, util­i­ties, or oth­er pub­lic facil­i­ties.
  6. The applicant’s cir­cum­stances are unique and do not estab­lish a pat­tern incon­sis­tent with the intent of the NFIP.
  7. All oth­er state and fed­er­al per­mits have been obtained.

(B) The Coun­ty Super inten­dent of High­ways shall noti­fy an appli­cant in writ­ing that a vari­ance from the require­ments of the build­ing pro­tec­tion stan­dards of Sec­tion 14–1–7 that would lessen the degree of pro­tec­tion to a build­ing will:

  1. Result in increased pre­mi­um rates for flood insur­ance up to Twen­­­ty-FiveDol­lars ($25.00) per One Hun­dred Dol­lars ($100.00) of insur­ance cov­er­age;
  2. Increase the risks to life and prop­er­ty; and
  3. Require that the appli­cant pro­ceed with knowl­edge of these risks and that the appli­cant acknowl­edge in writ­ing the assump­tion of the risk and lia­bil­i­ty.

(C) Vari­ances to the build­ing pro­tec­tion require­ments of Sec­tion 14–1–7 of this Code which are request­ed in con­nec­tion with the recon­struc­tion, repair, or alter­ation of a his­toric site or his­toric struc­ture as defined in “His­toric Struc­tures”, may be grant­ed using cri­te­ria more per­mis­sive than the require­ments of Sec­tions 14–1–6 and 14–1–7 of this Code sub­ject to the con­di­tions that:

  1. The repair or reha­bil­i­ta­tion is the min­i­mum nec­es­sary to pre­serve the his­toric char­ac­ter and design of the struc­ture.
  2. The repair or reha­bil­i­ta­tion will not result in the struc­ture being removed as a cer­ti­fied his­toric struc­ture.

For all projects involv­ing chan­nel mod­i­fi­ca­tion, fill, or stream main­te­nance (includ­ing lev­ees), the flood car­ry­ing capac­i­ty of the water­course shall be main­tained.

In addi­tion, the Coun­ty shall noti­fy adja­cent com­mu­ni­ties in writ­ing thir­ty (30) days pri­or to the issuance of a per­mit for the alter­ation or relo­ca­tion of the water­course.

(A) Pub­lic health stan­dards must be met for all flood­plain devel­op­ment.  In addi­tion to the require­ments of Sec­tions 14–1–6 and 14–1–7, the fol­low­ing stan­dards apply:

  1. No devel­op­ment in the flood­plain shall include locat­ing or stor­ing chem­i­cals, explo­sives, buoy­ant mate­ri­als, flam­ma­ble liq­uids, pol­lu­tants, or oth­er haz­ardous or tox­ic mate­ri­als below the flood pro­tec­tion ele­va­tion unless such mate­ri­als are stored in a flood­proofed and anchored stor­age tank and cer­ti­fied by a pro­fes­sion­al engi­neer or flood­proofed build­ing con­struct­ed accord­ing to the require­ments of Sec­tion 14–1–7 of this Code.
  2. Pub­lic util­i­ties and facil­i­ties such as sew­er, gas and elec­tric shall be locat­ed and con­struct­ed to min­i­mize or elim­i­nate flood dam­age.
  3. Pub­lic san­i­tary sew­er sys­tems and water sup­ply sys­tems shall be locat­ed and con­struct­ed to min­i­mize or elim­i­nate infil­tra­tion of flood waters into the sys­tems and dis­charges from the sys­tems into flood waters.
  4. New and replace­ment on-site san­i­tary sew­er lines or waste dis­pos­al sys­tems shall be locat­ed and con­struct­ed to avoid impair­ment to them or con­t­a­m­i­na­tion from them dur­ing 
    flood­ing.  Man­holes or oth­er above ground open­ings locat­ed below the flood pro­tec­tion ele­va­tion shall be water­tight.
  5. Con­struc­tion of new or sub­stan­tial­ly improved crit­i­cal facil­i­ties shall be locat­ed out­side the lim­its of the flood­plain.  Con­struc­tion of new crit­i­cal facil­i­ties shall be per­mis­si­ble with­in the flood­plain if no fea­si­ble alter­na­tive site is avail­able.  Crit­i­cal facil­i­ties con­struct­ed with­in the SFHA shall have the low­est floor (includ­ing base­ment) ele­vat­ed or struc­tural­ly dry flood­proofed to the 500-year flood fre­quen­cy ele­va­tion or three (3) feet above the lev­el of the 100-year flood fre­quen­cy ele­va­tion whichev­er is greater.  Flood­proof­ing and seal­ing mea­sures must be tak­en to ensure that tox­ic sub­stances will not be dis­placed by or released into flood­wa­ters.  Access routes ele­vat­ed to or above the lev­el of the base flood ele­va­tion shall be pro­vid­ed to all crit­i­cal facil­i­ties.

(B) All oth­er activ­i­ties defined as devel­op­ment shall be designed so as not to alter flood flows or increase poten­tial flood dam­ages.

The Coun­ty Board shall take into account flood haz­ards, to the extent that they are known, in all offi­cial actions relat­ed to land man­age­ment, use and devel­op­ment.

(A) New sub­di­vi­sions, man­u­fac­tured home parks, annex­a­tion agree­ments, planned unit devel­op­ments, and addi­tions to man­u­fac­tured home parks and sub­di­vi­sions shall meet the dam­age pre­ven­tion and build­ing pro­tec­tion stan­dards of Sec­tions 14–1–6 and 14–1–7 of this Code.  Any pro­pos­al for such devel­op­ment shall include the fol­low­ing data:

  1. The base flood ele­va­tion and the bound­ary of the flood­plain, where the base flood ele­va­tion is not avail­able from an exist­ing study, the appli­cant shall be respon­si­ble for cal­cu­lat­ing the base flood ele­va­tion;
  2.  The bound­ary of the flood­way when applic­a­ble; and
  3. A signed state­ment by a Licensed Pro­fes­sion­al Engi­neer that the pro­posed plat or plan accounts for changes in the drainage of sur­face waters in accor­dance with the Plat Act (765 ILCS 205/2).

(B) Streets, blocks, lots, parks and oth­er pub­lic grounds shall be locat­ed and laid out in such a man­ner as to pre­serve and uti­lize nat­ur­al streams and chan­nels.  Wher­ev­er pos­si­ble the flood­plains shall be includ­ed with­in parks or oth­er pub­lic grounds.

(A)               In addi­tion to the dam­age pre­ven­tion require­ments of Sec­tion 14–1–6, all build­ings locat­ed in the flood­plain shall be pro­tect­ed from flood dam­age below the flood pro­tec­tion ele­va­tion.  This build­ing pro­tec­tion require­ment applies to the fol­low­ing sit­u­a­tions:

(1)     Con­struc­tion or place­ment of a new build­ing or alter­ation or addi­tion to an exist­ing build­ing val­ued at more than One Thou­sand Dol­lars ($1,000.00) or sev­en­ty (70) square feet.

(2)     Sub­stan­tial improve­ments or struc­tur­al alter­ations made to an exist­ing build­ing that increase the floor area by more than twen­ty per­cent (20%) or equal or exceed the mar­ket val­ue by fifty per­cent (50%).  Alter­ation shall be fig­ured cumu­la­tive­ly sub­se­quent to the adop­tion of this Code.  If sub­stan­tial­ly improved, the exist­ing struc­ture and the addi­tion must meet the flood pro­tec­tion stan­dards of this Sec­tion.

(3)     Repairs made to a sub­stan­tial­ly dam­aged build­ing.  These repairs shall be fig­ured cumu­la­tive­ly sub­se­quent to the adop­tion of this Code.  If sub­se­quent­ly dam­aged the entire 
struc­ture must meet the flood pro­tec­tion stan­dards of this Sec­tion.

(4)     Installing a man­u­fac­tured home on a new site or a new man­u­fac­tured home on an exist­ing site.  (The build­ing pro­tec­tion require­ments do not apply to return­ing a man­u­fac­tured home to the same site it law­ful­ly occu­pied before it was removed to avoid flood dam­age).

(5)     Installing a trav­el trail­er or recre­ation­al vehi­cle on a site for more than one hun­dred eighty (180) days per year.

(6)     Repet­i­tive loss to an exist­ing build­ing as defined in Sec­tion 14–1–2.
