<br />B. HYDRAULICS (CONTINUED)
<br />
<br />3. Pre,Submittal Review of Hvdraulic Models
<br />
<br />FEMA has developed two review programs, CHECK,2 and CHECK,RAS, to aid in the review of HEC-2 and HEC-RAS hydraulic models,
<br />respectively. These review programs verify that the hydraulic estimates and assumptions in the model data are in accordance with NFIP
<br />requirements, and that the data are comparable with the assumptions and limitations of HEC,2/HEC,RAS. CHECK-2 and CHECK-RAS identify
<br />areas of potential error or concern. These tools do not replace engineering judgment. CHECK,2 and CHECK,RAS can be downloaded from
<br />http://www.fema.govlmit/tsd/frm_soft.htm. We recommend that you review your HEC-2 and HEC-RAS models with CHECK-2 and CHECK,
<br />RAS. If you disagree with a message, please attach an explanation of why the message is not valid in this case. Review of your submittal and
<br />resolution of valid modeling discrepancies will result in reduced review time.

<br />The document "Numerical Models Accepted by FEMA for NFIP Usage" lists the models accepted by FEMA. This document can be found at:
<br />http://www.fema.gov/mit/tsd/en_modl.htm.
<br />
<br />C. MAPPING REQUIREMENTS
<br />
<br />A certified topographic map must be submitted showing the following information (where applicable): the boundaries of the effective, existing, and
<br />proposed conditions 1 %,annuakhance floodplain (for approximate Zone A revisions) or the boundaries of the 1 %- and O.2%-annual-chance
<br />floodplains and regulatory floodway (for detailed Zone AE, AO, and AH revisions); location and alignment of all cross sections with stationing control
<br />indicated; stream, road, and other alignments (e.g., dams, levees, etc.); current community easements and boundaries; boundaries of the
<br />requester's property; certification of a registered professional engineer registered in the subject State; location and description of reference marks;
<br />and the referenced vertical datum (NGVD, NAVD, etc.).
<br />
<br />Note that the boundaries of the existing or proposed conditions floodplains and regulatory floodway to be shown on the revised FIRM and/or FBFM
<br />must tie,in with the effective floodplain and regulatory floodway boundaries. Please attach a copy of the effective FIRM and/or FBFM, annotated
<br />to show the boundaries of the revised 1 %- and 0.2%-annual-chance floodplains and regulatory floodway that tie-in with the boundaries of the
<br />effective 1 %' and 0.2%-annual-chance floodplain and regulatory floodway at the upstream and downstream limits of the area of revision.
<br />
<br />D. COMMON REGULATORY REQUIREMENTS
<br />
<br />1. For CLOMR requests, do Base Flood Elevations (BFEs) increase?
<br />
<br />DYes [8] No
<br />
<br />For CLOMR requests, if either of the following is true, please submit evidence of compliance with Section 65.12 of the NFIP regulations:
<br />. The proposed project encroaches upon a regulatory floodway and would result in increases above 0.00 foot.
<br />. The proposed project encroaches upon a SFHA with BFEs established and would result in increases above 1.00 foot.
<br />
<br />2. Does the request involve the placement or proposed placement of fill?
<br />
<br />[8] Yes D No
<br />
<br />If Yes, the community must be able to certify that the area to be removed from the special flood hazard area, to include any structures or
<br />proposed structures, meets all of the standards of the local floodplain ordinances, and is reasonably safe from flooding in accordance with the
<br />NFIP regulations set forth at 44 CFR 60.3(a)(3), 65.5(a)(4), and 65.6(a)(14). Please see the MT-2 instructions for more information.
<br />
<br />3. For LOMR requests, is the regulatory floodway being revised?
<br />
<br />DYes D No
<br />
<br />If Yes, attach evidence of regulatory floodway revision notification. As per Paragraph 65.7(b)(1) of the NFIP Regulations, notification is required
<br />for requests involving revisions to the regulatory floodway. (Not required for revisions to approximate 1 %,annual-chance floodplains [studied
<br />Zone A designation] unless a regulatory floodway is being added. Elements and examples of regulatory floodway revision notification can be
<br />found in the MT-2 Form 2 Instructions.)
<br />
<br />4. For LOMR requests, does this fequest require property owner notification and acceptance of BFE increases?
<br />
<br />DYes D No
<br />
<br />If Yes, please attach proof of property owner notification and acceptance (if available). Elements of and examples of property owner notification
<br />can be found in the MT,2 Form 2 Instructions.
