Riverchase(5)-CN 861112CONTRACT DOCUMENTS and SPECIFICATIONS [or RECLAMATION PLAN tO RIVERCHASE DEVELOPMENT COPPELL, TEXAS for NORTHWEST. DALLAS COUNTY FLOOD CONTROL DISTRICT NOVEMBER 1986 CONSULTING INGINESIS, INC. Dillml, Texie ' FEDERAL EMERGENCY MANAGEMENT AGENCY AUGUST. 1984 Conditions and Criteria for FLOODWAY REVISIONS CONDITIONS ~ND CRITERIA FOR FLOODWAY REVISIONS FOREWORD The National Flood Insurance Program makes flood insurance available to property owners in communities that adopt and enforce flood plain management measures to reduce future flood losses. The Program provides' flood hazard maps and risk information on which local flood plain management measures are based. One aspect of a sound flood plain management program is the maintenance of a floodway area to assure that the elevations of future floods will not be increased significantly. The adoption of a floodway by a community preserves the necessary conveyance area for passage of the flood waters by restricting actions within the floodway which will result in any increase in flood elevation. After a floodway-is adopted, a community may encounter a compelling need to change the configuration of their floodway and therefore request that the floodway map prepared by the Federal Emergency Management Agency (FEMA) be revised. The purpose of these conditions and criteria is to set forth the nature and extent of the material needed to support such a request. Compliance with the criteria described herein will allow FEMA to review the material and revise the floodway maps as appropriate in a timely manner. ministrator Federal Insurance Administration This document sets forth FEMA policy concerning requests for revising the Flood Boundary ~nd Floodway Map (FBFM) prepared by FEMA for ~doption by the community to regulate floodways In accordance with Title 44, Part 60.3(d) of the Code of Federal Regulations. A. FE~A ~ole in Establishing Floodways The Mational Flood Insurance Act of 1968, Section 1361 authorized FEMA to carry out flood studies relating to encroachments and obstructions on stream channels and floodways. The purpose of the studies is to support state and local efforts to: (1) regulate the development of land which is exposed to flood damage, where appropriate, (2) guide proposed construction ·way from locations which are threatened by flood hazard, (3} assist in reducing damages caused by floods, and (4) otherwise improve the long-range land management and use of floodprone The eection Is explicit in that FEMA shall ~:~k closely with, and provide necessary technical assistance to, state, lnte=state, ·nd local government agencies in their efforts toward sound flood plain management. The FEMA role consists of establishing minimum standards ·nd providing information to state ~nd local regulating agencies. Established criteria ·re contained in Part 60.3 (d) of Chapter 1, Title 44 of the Code of Federal Regulations. The regulation states that when FEMA has provided data frou which a regulatory floodway shall be designated, the co~nunity shall select and adopt · regulatory floodway based on the principle that the ·re· chosen for the regulatory floodway Bust carry the waters of the base flood (100-year) w~thout increasing the water surface elevation of that flood Bore than 1.0 foot ·t any point. However, the community may adopt · Bore restrictive floodway in which the surcharge limit is less than 1.0 foot. The FEMA role, therefore, is to provLde data from which the connunity can formulate and adopt a floodway for regulatory purposes. Fro~ · practical standpoint, FEMA' coordinates with munities during the data generation stage and prepares data on · single floodway delineation which reflects co~unity input. Once · floodway is adopted by the co~aunity, FEMA continues to support the comunity in its efforts to enfo£~e the floodway ~nd provides copies of the maps to users. Bo Definition and Purpose of Floodway The floodway Is defined ·s the channel of a stress and any ~j&cent £1oo~ plain areas that must be reserved in order to discharge the 100-year flood without increasing floed bights by a specified onount. The purl~se for establishing a £1oodeay is to provide for the balancing of the competing uses of development ·gainst the resulting increase in floo~ hazards. ~ has set · min~num standard, limiting the floodway width to that Which will not result in an increase of the 100-year flood by more than 1.0 foot. Sever·l states have ·dopted requirements which limit the increases to less than the FEP~ minhnum standard. In cases where the state has adopted more stringent standards by legally enforceable st·tuts or regulation, FE~IA co, utes floodway· based upon these standards. Once the £loodway has been adopted, encroaclunents, including fill, new construction, substantial ~nprovements, and other development within the · dopked floodway that ~uld result in any increase in floo~ levels.within the co~munity during the occurrence of the l~ase flood discharge is p r oh ib i ted o Co Floodway Revision - General Policies #ithin the criteria established by FEHA, many floodway configurations may be generated. However, once adopted by · con~nunity, · particular floodway configuration becomes &dministratively estab].ished, much the same ·s other community regulations. An adopted floodway represents a reasonable allocation of an area for the passage of flood waters and does not necessarily represent the minimun area required to meet the FF.~ minimum standard. Once the floodway is adopted, ~he floodwsy boundaries imring · restudy, the existing floodwsy configuration should be checked to assure that it Beets ·cceptable surcharge limits under present conditions. Uhere surcharge l~nits are exceeded, the floodway should ~e exl~anded. A floodway may be reduced ~n alze if the discharges have been reduced as · result of · physical change, such as · diversion of the flo~, or the cc~struction of & dam or other ma~or retention measures. A floodway may also be reduced &s · result of stremn modifications. Flocx~way changes should not be based on physical changes, unless It has been established that adequate maintenance has been provided to assure continuation of the s~uctural effects. A further basis for · floodway revision is the desire by · connunity to respond ~o a social or economic need for develol~ent within a floedway. This need may be net by shifting the floodway boundaries, using appropriate hydraulic analysis, while maintaining the flood carrying capacity of the floodway. - A~ter s floodway is established, develol~nent may occur In the ~ringe area (the area within the flood plain but outside the floodway), but should not occur in the floodway unless it is cho~n that the development will not reduce the conveyance of the floodway. If it becones necessary to revise the £1oodway, the original hydraulic model must be used to establish the base profile £or the new encroachment analysis. The model uould then be modified to include the in-place encroachment for the revised floodway runs. Do Conununit¥ Floodway Map Revision Request The floodway designatic~ is not Uappealable- to FENA by individuals, · inca it is the conmunity l~at ·elects and adopts the regulatory floodway. Thus, an individual should appeal the floodway designation to, or seek amendments £rom, the connunity. The connunity, in turn, may support the amendment and request FENA to revise the original, FENA- produced Flood Boundary and Floodway Map (FBFI4) · FENA will review the request to ascertain that the £olloving conditions are met before expending effort cm the revision.- Condition Number l The con~unity must demonstrate that it is prepared to adopt the modified £1oodway and that all legal requirements will have been met before '~he £1oodway is revised· Before changes are m&de to community £egulated areas, communities are required by the state to follow certain administrative procedures. The request to FZNA needs to include evidence that appropriate procedures have been followed. Typical information to be ·ubnitted are as 1.1 Copy o£ a public notice of the intent to modify the floodway. 1.2 & statement that the cou~unity has notified, and obtained approval from, any adversely impacted property owners o~ adjacent Jurisdictions. ~.3 In lieu o£ the above, a statement that the change will result in no adverse impact. ~.4 A copy o£ the notification of the £1oodway change to the state. Condition Humber 2 An engineering ~nalysis has been performed to substantiate that the revised floodway Beets coonunity requirements. Floodway revisions must be based on the hydraulic model used to develop the floodway currently in effect. The community should request, through the FEHA Regional O~fice, · copy of the input data used in the conpu~er model for its effective Flood Insurance Study. Uhere the input data representing the or approximation should be developed. A new model should be established using the original cross section topographic information, where possible, and the discharges contained in the Flood Insurance Study which established the original £1oodway. The model must uae the sane effective flow areas as established in the original analysis and be calibrated to reproduce the original base flood elevations within Ool foot. ~here reproductioo of the original base flood elevations w/thin 0.1 foot is not possible, or results in unsound engineer/n9 practices, the co. unity should contact the appropriate FEH~ Regional Office for direct/on. After the model has been checked and Batches the original base flood elevations, the model can be modified for new floodway runs. The analysis will be accoa~lished as specified for the following basis for revision~ Discharge Decreases Floodways Bay' be revised when a base flood discharge decreases as a result of structural is~rovements, such as the construction of a flood control dam or other significant retention facilities. Floodways should not be revised based cma computed discharge reduction which results from changed methodology or longer strea~ 9age records, unless the change is statistically significant. The statistical significance criteri~ are discussed in Secticm 2-6 'i~ydfologic Analyses' of FE~A's Guidelines and Speci[ications for Study Contractors (dated September 1982). IA' cases vhe:e the statistical significance test does not apply, a determinat$on by a state or Federal agency that the change is significant Bay be accepted as a basis for a floodway revision. If evident that the change is statistically significant, the original hydraulic model should be rerun, changing only the discharges. This will serve as .the base run for the subsequent floodway encroachment runs. The floodway model should then be modified to include current conditions, as well as any encroachment that Bay have occurred since the original model was produced. The resulting floodway elevations must not ex~eed the base run elevations by more than 1o0 foot, or as specified by the state or connunity. Discharge Increases If watershed conditions have resulted in a significant increase in discharge, the original hydraulic model needs to be run with the increased discharges. The resulting base flood profile will serve as the base for the floodway runs. The floodway runs must include any encroachnent that Bay have occurred since the delineation of the original floodway. Channel Modification The original model will be modified to include the Channel modification, and any other encroachment occurring subsequent to the original floodway delineation. The resulting base flood.profile will serve as the base for the floodway runs. The floodway runs must include &ny encroachment that may have occurred since the delineation of the original floodway. 'The - resulting floodway elevations must not exceed the new base flood elevations or the o~iginal base flood elevations by more than 1.O foot, or as specified by the state or coumunity. Social or Economic Where it is desired to shift the floodway for ~ocial or economic reasons, the base flood elevations from the original model would serve as the base profile for the new floodway run. The model would then be modified to account for any encroachment in the flood plain since the original study. The new floodway l~units are to be set in a ~anner which will ~ot result in an lr~rease to the original base flood elevation in excess of that permitted by FEMA or the state. Condition Number 3' Submittal includes technical data that enables FEMA to determine whether the floodway revision meets the FEMA minimum standard. Submittal must include the following: 3.1 A copy of the printout for the original hydraulic computer model representing the 100-year flood profile run for conditions eaisting et the time the currently effective floodway was developed. The printout must include full input and output listings. 3.2 A copy of the printout for the original hydraulic computer model representing the floodway run for conditions under which the currently effective floodway was developed. The printout must include full input and output listings. 3.3 A copy of the pr intout ' from the hydraulic computer model representing the new 100-year profile. The model should be the lame as that used in item 3.1, but modified to include any channel ~odification, fill or other encroachment that may have occurred in the flood plain since the original floodway was delineated. 3.4 A copy of the pr intout from the hydraulic computer model representing the floodway run for the proposed floodway, including channel ~odifications and encroachments since the original floodway was established. The equal conveyance reduction method should be used to compute the revised floodway limits unless agreements have been ~ade with affected property owners to utilize a different ~ethod. The printout must include full input and output listings with lll input changes from the original model highlighted. The net effect of the channel ~difioations, the encroachments made subsequent to the establl'shment of the original floodway, and the new proposed floodway limits must not increase the water surface elevatio~ by more than 1.0 foot above that computed in item 3.1, and also must not exce%d 1.0 foot above the new 100'-~ear elevations computed in item 3.3. 3.5 A copy of the revised Floodway Data Table representing data for the proposed floodway configuration. 3.& One ~ of the currently effective FBFM showing the existing floodwe~f and one copy showing the proposed floodway configurations. 3.7 Certification from a registered professional engineer that the physical parameters used in the proposed floodway delineation represent actual conditions and that the standards contained in these "Conditions and Criteriat are net. 3.8 If the basis for the proposed floodway revision is a channel ~odification, the com~letion of · dam, or any other structural measure, evidence is required to demonstrate the design is adequate, ·nd that neintenance ·nd operation provisions, where applicable, have been made. The submittal mst indicate what entity has maintenance responsibility and hoe maintenance will be accoa~lished. If maintenance is to be accomplished by agencies other than the ~oamunity, · legal provision for community monitoring and back-up assistance is required. 3.9 Documentation of approval of the proposed floodway revision from the appropriate state agency for communities where the 'state regulates the floodway. 3.10 Documentation of any variation from Condition 2 and/or Condition' 3. This includes approval frc~ the appropriate agencies and an explanation of the reason for variation. FEMA Itesponse to Floodway Revision lte~uest FEMA will review · coa~unity's request for · floodway map revision. It is recognized, that while the floodway is adopted by · community, Flood Insurance Study users other than the community may request copies of the floodway delineations. Therefore, In support of the community and other users, FENA maintains · syste~ for distributing floodway information and revising delineations as the need arises. When the revision ia considered to be significant, FEMA will revise floodway maps and distribute them to recognized, users. Significant floodway revisions are identified based on the size of ·rea, as well as the number of interests affected by the revision. FBMA viii respond to a request from the ~unity for a floodway revision by one of the following means: (1) Reprinting the affected FBFM panels with corresponding map revised dates. The panels will be accompanied by · revised index panel showing the most up-to-date floodway panels maintained at FEMA. Copies of the revised floodway panels will be sent to previous recipients of the floodway maps. A revised Flood Insurance Study · .report will accompany the floodway naps. Included in the report viii b~ · description of the revision and revised Floodway Data Tables. {2) Bend one c,~py of the FBFM designating the approved floodway revision to the community, and · letter of £1oodway revision stating that the review of the submitted material has resulted in the determination that FEMA minimum requirements have been net but · reprinting of the FBFM is not nrranted at this time. The 6 m~terial, ~ncluding the copy of the FBFN showing the revised flooduay, will be filed for lncorporatio~ at · later t~ne into a £1oodvay map revision. The approved FBFld revision copies will be dated. Since it ia possible that FE~A has responded to · floodway revision request in this manner, all Flood Insurance Study users are encouraged to contact the comunity before proceeding with plans for developnent within the £~ood fringe areas or near floodwaya. (3) Send · letter to the connunity at·ting that the submittal material is lncouplete and/os that the revised floodway does not Met FF.~A min~uun criteria. F. Subnittal of lquterial Submit material to the lPn4A Regional Office. The Regional Office will review material for co, let·ness, concur with the proposed c~anges0 &pprove any maintenance ordinances, and forward the necessary material to the FE~A Central office. FE~A Central will review the hydrologic/hydraulic back-up mater eng~neering design, and any plans of ogerat~on and maintenance (where appropriate), request additional revisions or corrections as necessary, then respond to the coununity by ma·ns of the appropriate-action defined under Section · above. .G. To obtain £u~ther information on the conditions and criteria for floodway revisions, communities are encouraged to contact the appropriate Regional Office or ~ Central in #sshington, D.C. at (202) 287-0230, prior to the request for · floodway revision. CONDITIONS AND CRITERIA FOR MAP REVISIONS A. Introduction This document describes the conditions and criteria for revising a Flood Insurance Study (FIS) under Part 65 of the National Flood Insurance Program (NFIP) regulations. The Federal Emergency Management Agency (FEMA) recognizes that FISs may require revision due to new information becoming available or through physical changes in flood plains. This document defines the situations that fall under Part 65 of the NFIP regulations and describes the procedures for correcting or updating Flood Insurance Rate Maps (FIRMs) and Flood Boundary and Floodway Maps (FBFMs). B. Definitions A Letter of Map Amendment (LOMA) issued under Part 70 of the NFIP regu- lations indicates whether or not a structure(s) or proposed structure(s) is located in a Special Flood Hazard Area (SFHA) as shown on a FIRM or Flood Hazard Boundary Map (FHBM). A LOMA removes a property from the SFHA and thereby makes inapplicable the Federal requirement for the purchase of flood insurance. For more information regarding LOMAs, refer to "Condi- tions and Criteria for Letters of Map Amendment." A Conditional Letter of Map Revision, or belief letter, issued under Part 65 of the NFIP regulations is FEMA's comment on the effectiveness or impacts of a proposed flood control project or flood plain modification. It is based on FEMA's review of the proposed project and states that were the proposed project built as designed, it would be cause for a map revision. A Letter of Map Revision (LOMR) can be issued under Part 65 of the NFIP regulations as an expeditious means of revising a FIRM or FBFM. The LOMR gives a detailed description of the Base Flood Elevation (BFE) and graphic changes that will be made to the SFHA currently delineated on the effec- tive FIRM and/or FBFM. LOMRs involving BFE changes are always succeeded by a physical map revision. A physical map revision under Part 65 of the NFIP regulations involves changing and republishing the existing FIRM and/or FBFM to reflect any updated condition. Valid LOMAs and LOMRs are incorporated into map revisions. Co Reasons for Revision FEMA will revise an effective FIS to reflect new information which shows the original FIS to be incorrect and to reflect physical changes which invalidates the original FIS analyses or presentation of data. Updated or corrected topographic mapping, hydrologic data, or hydraulic data FIA/ORA/RSD 7/2 7/84 constitute new information which may warrant a revision. Flood protection projects and any form of topographic alterations (cut and fill) constitute physical changes which may also warrant a map revision. D. General Revision Policy Within the statutory criteria established for appeals, revision requests will be evaluated based on the possession of knowledge or information indicating that the effective elevations are scientifically or technically incorrect. In certain situations where new information shows mathematical or measurement errors in the original FIS, FEMA will accept the respon- sibility for revising the FIS provided the requestor submits the basic data necessary to correct the problem. Where revision requests are based on the application of alternative methods, appellants are required to demonstrate that the new analyses result in more correct estimates of base flood elevations, thus demonstrating that FEMA' s estimates are incorrect. In these situations, where a revision request is being made based on improved data, methods, or applications, the community (or requestor through the community) must accept responsibility for providing all data and analyses necessary to u~date the FIS. If a physical change resulting from development warrants a revision to the existing analyses, FEMA will not undertake this new technical analysis. The requestor, through the community, must accept responsibility for providing all data-and analysis necessary for u~dating the FIS. E. Community Map Revision Requests The map revision process cannot be initiated without the community's endorsement since it is the community that adopts the effective FIS. Therefore, any individuals requesting a change to the FIS, must do so through the community. The community, in turn, may support the request and forward the information to FEMA for evaluation. FEMA will review the request to ascertain that the following conditions are met before eval- uating the revision request. Condition N~_~mber 1 The community must endorse the revision request and demonstrate prepared- ness to accept responsibility for the operation and/or maintenance of any structural measures (e.g. channel improvements or levees) involved. The request submittal should include the following: 1 .1 A statement that the community endorses the re%ision request. 1 .2 If the basis for the revision request is a channel modification, the completion of a dam, levee, or any other structural measure, evidence is required to demonstrate the design is adequate and that mainte- nance and operation provisions, where applicable, have been made. The submittal must indicate what entity has operation and maintenance responsibility and how they will be accomplished. If maintenance is to be accomplished by an agent other than the community, a legal 2 provision (ordinance) for community monitoring and backup maintenance is required. 1.3 The submittal must indicate that, where necessary, state approval of the revision has been obtained. Condition N,,mher 2 If the revision request is based on information showing a mathematical or measurement error in the original analysis, the submittal must include the following: 2.1 Documentation that identifies the specific source of the error. 2.2 A written description of the new information and how it differs from the existing FIS information. 2.3 Basic data supporting the revision request to enable FEMA to revise the FIS. In most cases, this data must be certified by a registered professional engineer or licensed land surveyor. Updated topographic maps, revised community boundary maps including annexation ordi- nances, and channel, dam, or bridge structure plans'which illustrate the correct dimensions are examples of the basic data required. Condition N-mher 3 If the revision request is based on improved application of hydrologic, hydraulic, or other methods, or use of better data in applying such methods, the requestor must submit the following: 3.1 Documentation that identifies the error in the application or in the inferior data in the original analysis and supports why the appli- cation is incorrect or the data is inferior. 3.2 Engineering analyses applying the same basic methods utilized by FEMA but with the changes itemized. 3.3 Alternative engineering analyses utilizing the methods or assumptions determined to be correct. 3.4 Background technical information which supports the requestor's changes as being more correct. 3.5 Cer'tification by a registered professional engineer or license~ land surveyor of the correctness of any alternate data utilized or mea- surements made. 3.6 Documentation of all locations where the requestor's base flood elevations are different from FEMA's. Ail engineering analyses performed must substantiate that the revised hydrologic or hydraulic analyses meet FEMA requirements as well as any state or community requirements. F. General Technical Guidance Flood plain revisions should be based on the hydraulic model used to develop the flood profile and flood boundaries currently in effect. The community should request, through the FEMA Regional Office, a copy of the input data used in the computer model for its effective FIS. Where the input data representing the original hydraulic model is unavailable, or where a technically superior model can be used, an approximation should be developed. A new model should be established using the original cross- section topographic information, where possible, and the discharges contained in the FIS which established the original BFEs. The model must use the same effective flow areas as established in the original analysis and must be calibrated to reproduce the original base flood elevations within 0.1 foot. Any differences between the new analysis and the orig- inal profile must be justified on an engineering basis. After the model has been checked and matches the original base flood elevations, the model can be modified for new flood plain runs. The analysis will be accomplished as specified for the following conditions: Discharge Decreases. Hydraulic analyses may be revised when a base flood discharge decreases as a result of structural improvements, such as the construction of a flood control dam or other significant retention faoil- ities. Hydraulic analyses should not be revised based on a computed discharge reduction which results from chang6d methodology or longer stream gage records, unless the change is statistically significant. The statistical significance criteria are discussed in Section 2-6 "Hydrologic Analyses" of FEMA's Guidelines and Specifications for Study Contractors (dated September 1982). If it is evident that the change is statistically significant, the original hydraulic model should be rerun, changing only the discharges. In cases where the statistical significance test does not apply, a determination by a state or Federal agency that the change is significant may be accepted as a basis for a map revision. Discharge Increases. If watershed conditions have resulted in a signifi- cant (defined as above) increase in discharge, the original hydraulic model must be run with the i~creased discharges. Channel Modification. The original hydraulic model will be modified to include'~he channel modification, and any other encroachment occurring subsequent to the original flood plain delineation. In all situations, the revised hydraulic analysis should be modified to include current conditions as well as any encroachment to the flood plain that may have occurred since the original model was developed. The revised hydraulic analysis should also include a zone determination, and if only a portion of the existing hydraulic analysis is revised, the upstream and downstream portions of the revised analysis should coincide 4 with the effective FIS profiles, i.e., hydraulic calculations should be continued for a great enough distance upstream and downstream of the revised area until water-surface elevations coincide with those in the effective FIS. The submittal must include the technical data that enables FEMA to deter- mine whether the flood plain revision meets FEMA's requirements. The sub- mittal must include the following: o A copy of the printout for the original hydraulic computer model representing the 100-year flood profile run for conditions existing at the time the currently effective hydraulic analysis was developed. The printout must include full input and output listings. o A copy of the printout from the hydraulic computer model repre- senting the new 10-, 50-, 100-, and 500-year profiles. The model should be the same as that used in the preceding item, but modified to include any channel modification, fill or other encroachment that may have occurred in the flood plain since the original flood plain was delineated. o Delineation of the 100- and 500-year flood boundaries and the location and alignment of cross sections and flow line used in the hydraulic model. This information should be shown on a map of suitable scale and topographic definition to provide reason- able accuracy. o A copy of the currently effective flood profiles showing the existing and 'the revised flood elevations. o Certification from a registered professional engineer that the physical parameters used in the proposed flood boundary delin- eation represent actual conditions and that the standards contained in these "Conditions and Criteria" are met. When a map is revised as a result of a new hydraulic analysis, the effect of the revised hydraulics on the floodway must also be considered. If a revised floodway analysis is necessary, the community should refer to the "Conditions and Criteria for Floodway Revisions" for additional informa- tion that will be required. G. FEMA Response to Map Revision Request FEMA will evaluate a request from the community for a revision and respond by one of the following means: (1) A preliminary copy of the revised FIS will be sent to the community for their review. If the revision involves BFE changes or the estab- lishment of new BFEs, FEMA will initiate a 90-day Appeals Period. Upon review and resolution of any comments and/or appeals received, FEMA will issue a new effective FIS which will be sent to all pre- vious recipients of the maps. 5 (2) Send a Letter of Map Revision (LOMR) to the community stating that the review of the submitted material has resulted in an official map revision but that a physical map revision is not warranted at this time. The LOMR will give a detailed description of the BFE and graphic changes that have been made to the SFHA currently delineated on the effective FIS. The material, including a copy of the Maps showing the revised information, will be filed for incorporation at a later time into a physical map revision. The approved map revision copies will be dated. Since it is possible that FEMA has responded to a map revision request in this manner, all FIS users are encouraged to contact the community before proceeding with plans for development within the flood plain areas. LOMRs that result in an increase in BFE will also be preceded by a 90-day appeals period. An appeals period for a LOMR which only decreases BFEs will be provided subse- quent to the issuance of the LOMR. (3) Send a letter to the community with a copy to any other requestor stating that the submitted material is not adequate to make an evaluation and offer them the option of submitting additional infor- ma tion. (4) Send a letter to the community with a copy to any o~her requestor stating that the submitted material appears to justify a map re- vision, but because not enough information was submitted the com- munity will be placed on a list for restudy consideration, as funds permit, unless the community can submit additional information. (5) Send a letter to the community with a =opy to any other requestor stating that the submitted material does not substantiate their request for a map revision and that the file will be closed unless the community can submit additional information to substantiate their request. H. Submittal of Material Submit material to the FEMA Regional Office. The Regional Office will review material for completeness, concur with the proposed changes, approve any maintenance ordinances, and forward the necessary material to FEMA Headquarters. FEMA Headquarters will review the hydrologic/hydraulic backup material, e~lgineering design, and any plans of operation and maintenance (where ap- propriate), request additional information as necessary, then respond to the community by means of the appropriate action defined under Section F To obtain further information on the conditions and criteria for map revisions, communities are encouraged to contact the appropriate FEMA Regional Office or FEMA Headquarters in Washington, D.C., at (202) 287- 0230, prior to requesting a map revision. 6 CONSULTING ENGINEERS, INC.

After receiving said notice of abandonment the CONTRACTOR shall not remove from the work any machinery, equipment, tools, materials or supplies then on the job, but the same, together with any materials and equipment under contract for the work, may be held for use on the work by the OWNER or the Surety on the performance bond, or another contractor in completion of the work; and the CONTRACTOR 8hall not receive any rental or credit therefor (except when used in connection with Extra Work, where credit shall be allowed as provided for under Section 6, Extra Work and Claims), it being understood that the use of such equipment and materials will ultimately reduce the cost to complete the work and be reflected in the final settlement. Where there is no performance bond provided or in case the Surety should fail to commence compliance with the notice for completion hereinbefore provided for, within ten (10) days after 8ervice of such notice, then the OWNER may provide for completion of the work in either of the following elective manners: 7.01.1 The OWNER may thereupon employ 8uch force of men and use such machinery, equipment, tools, material8 and supplies as said OWNER may deem necessary to complete the work and charge the expense of such labor, machinery, equipment, tools, material8 and supplies to said CONTRACTOR, and expense so charged shall be deducted and paid by the OWNER out of such moneys as may be due, or that may thereafter at any time become due to the CONTRACTOR under and by virtue of this Agreement. In ca8e such expense is le88 than the sum which would have been payable under thl~ contract, if the same had been completed by the CONTRACTOR, then said CONTRACTOR shall receive the difference. In case such expense 18 greater than the sum which would have been payable under this contract, if the same had been completed by 8aid CONTRACTOR, then the CONTRACTOR and/or his Surety shall pay the amount of such excess to the OWNER; or 7.01.2 The OWNER under sealed bids, after flve (5) days notice published one or more time8 In a newspaper having general circulation in the county of the location of the work, may let the contract for the completion of the work under substantially the same terms and conditions which are provided in this contract. In case any Increase in c08t to the OWNER under the new contract as compared to what would have been the cost under this contract, such increase 8hall be charged to the CONTRACTOR and the Surety 8hall be and remain bound therefor. However, should the cost to complete any such new contract prove to be less than what would have been the cost to complete under this contract, the CONTRACTOR and/or his Surety shall be credited therewith. When the work 8hall have been substantially completed the CONTRACTOR and his Surety shall be so notified and Certificate8 of Completion and Acceptance, as provided in Paragraph 5.06 hereinabove, shall be issued. A complete itemized statement of the contract accounts, certified by the ENGINEER as being correct, shall then be prepared and delivered to the CONTRACTOR and his Surety, whereupon 5-18 the CONTRACTOR and/or his Surety, or the OWNER as the case may be, shall pay the balance due as reflected by said statement, within fifteen (15) days after the date of such Certificate of Completion. In the event the statement of accounts shows that the cost to complete the work is less than that which would have been the cost to the OWNER had the work been completed by the CONTRACTOR under the terms of this contract; or when the CONTRACTOR and/or his Surety shall pay the balance shown to be due by them to the OWNER, then all machinery, equipment, tools, materials or supplies left on the site of the work shall be turned over to the CONTRACTOR and/or his Surety. Should the cost to complete the work exceed the contract price, and the CONTRACTOR and/or his Surety fail to pay the amount due the OWNER within the time designated herelnabove, and there remains any machinery, equipment, tools, materials or supplies on the site of the work, notice thereof, together with an itemized list of such equipment and materials, shall be malled to the CONTRACTOR and his Surety at the respective addresses designated In this contract, provided, however, that actual written notice given in any manner will satisfy thls condition. After malling, or other glvlng of such notice, such property shall be held at the risk of the CONTRACTOR and his Surety subject only to the duty of the OWNER to exerclse ordinary care to _ protect such property. After fifteen (15) days from the date of said notice the OWNER may sell such machinery, equipment, tools, materials or supplies and apply the net sum derived from such sale to the credit of the CONTRACTOR and his Surety. Such sale may be made at either public or private sale, with or without notice, as -- the OWNER may elect. The OWNER shall release any machinery, equipment, tools, materials, or supplies, which remain on the work, and belong to persons other than the CONTRACTOR or his Surety, to their proper owners. The books on all operations -- provided herein shall be open to the CONTRACTOR and his Surety. ?.02 ABANDOW#gNTBVOWWRR.
