evee system h... relatively high vul- ,erability. FEMA may require that ther design criteria li.nd analyses be ubmitted to show that the levees pro- ide adequate protection. In such situ- tions, sound engineering practice will e the standard on which FEMA will ...e its determinations. FEMA wllI Iso provide the rationale for reQulr- g this additional information. (0) Operation plans and criteria. For levee system to be recognized, t.he perational criteria must be as de~ cribed below. All closure devices or echanical systems for intel'nal drain. ge, whether manual or automatic, list be operated in accordance with officially adopted operation anual. a copy of which must be pro- ided to FEMA by the operator when evee or drainage system recognition is eing sought Or when the manual for previously recognized system is re- ised In any manner. All operations ust be under the jurisdiction of a ederal or State agency. an agency reated by Federal or State law, or an gency of a community participating the NFIP. (1) Closures. Operation plans for clo- ures must include the following: (1) Docwnentatlon of the flood warn- g system. under the Jurisdiction of ederal. State. or community officials. hat will be used to trigger emergency peration activities and demonstration hat sufficient flood warning time xists for the completed: operation of 11 closure structures, including neces- ary sealing, before floodwaters reach he b...e of the closure. (in A formal plan of operation in- ~luding specific. actions and assign- nents of responsibility by individual lame or title. I (Hi) Provisions for periodIc oper- tion, at not less than one .year inter- als, of the closure structure for test- ng and t,rainfng purposes. ~(2) Interior dra.inage systems. lnt.eri- r drainage .s~.stems associated with vee systems usually include storage ,ress, gravity outlets, pumping sta- ons, or a. combination thereof. These rainage systelnS will be recognized by MA on Nfl:? maps for flood protec- on purposes only if the following inimum criteria are included in the eration plan: (!) Documentation of the flood warn. Ing system. under the Jurisdiction of Federal, state. or community officlals. that will be used to trigger emergency operation activities and demonstration that sufficient flood warning time exists to permit activation of mecha- nized portions of the drainage system. (iI) A formal plan of operation in. eluding specl.flc actions and assign- ments of responsibility by individual llame or title. (Hi) Provision for manual backup for the activation of automatic system.s. (tv) Provisions for periodic inspec- tion of interior drainage systems and periodic operation of any mechanized portions for testing and training pur- poses. No more than one year shall elapse between either the inspections or the operations. (3) Other operation plans and crite- ria. Other operating plans and criteria may be required by FEMA to ensure that adequate protection Is provided in specific situations. In such cases, sound emergency management prac. tice wlll be the standard upon which FEMA determinations will be b...ed. <d) Maintenance plans and criteria. For levee systems to be recognized as providing protection from the base flood, ~he maintenance criteria must be as described herein. Levee systems must be maintaipcd in accordance with an officially adopted mainte- nance plan. and a copy of this plan must be provided to FEMA by the owner. of the levee system when recog. nition is being sought or when the plan for a previOUSly recognized system is :revi$ed in any manner. All ma.intenance activities must be under -the Jurisdictioll of fl. Federal or Stat,e agency. an agency created by Federal or State law, or an agency of a commu. nity particlpating In the NFIP that must as:sume ultimate responsibility for maintenance. This plan- must doca- mBnt the fonnal procedure that en- sures that the stab!llty. height. and overall integrity of the levee and its associated structures and systeln.$ are maintained. At a minimum, mainte- nance plans shall specify the mainte- nance activities to be performed, the frequency of their -performance, an.d the person by name or title responsi- ble for their performance. 360
