Recently, FEMA completed a re-evaluation of flood hazards in your community. On January 27, 1995, FEMA issued a Letter of Map Revision (LOMR) to revise the effective FIRM, Flood Boundary and Floodway Map (FBFM), and Flood Insurance Study (FIS) report for your community to show the effects of the re-evaluation on the flood hazard information for Las Trampas Creek, San Ramon Creek, San Ramon Creek-Overflow, Sans Crainte Creek, Sans Crainte Tributary A, and Tice Creek, including the elevations of a flood having a 1-percent chance of being equaled or exceeded in any given year(base flood). The proposed modified base flood elevations (BFEs) for your community were published in the Contra Costa Times on February 23 and March 2, 1995. In a letter dated June 7, 1995, FEMA notified your community that the statutory 90-day appeal period, which was initiated on the second newspaper publication date cited above, had ended, and FEMA did not receive any appeals of the proposed modified BFEs during that time. Because no appeals of the proposed modified BFEs were received, the LOMR issued on January 27, 1995, remained in effect. On the same date as the LOMR, FEMA provided your community with preliminary revised copies of the FIRM, FBFM, and FIS report that reflect the.flood hazard information effected by the LOMR. Your community was provided with a 30-day period to review and provide comments on the revised FIRM and FIS report. We did not receive any comments during that review period. However, in a letter dated February 24, 1995, Mr. F. J. Kennedy, City Engineer, City of Walnut Creek, requested that FEMA revise the corporate limit boundaries shown on the preliminary revised FIRM for the City of Walnut Creek to reflect recent annexations. In a letter dated March 16, 1995, we notified Mr. Kennedy that we would revise FIRM Panels 0001 C and 0003 C for the City of Walnut Creek before the FIRM becomes effective. We also notified Mr. Kennedy that we would make appropriate changes to FIRM Panels 0290 C and 0295 C for Contra Costa County. Because all comments on the preliminary revised FIRM and FIS report submitted to FEMA have been addressed, the revised FIRM and FIS report will become effective on May 20, 1996. Before the effective date, FEMA will send you printed copies of the revised FIRM and FIS report. 2 Because the revised FIRM, FBFM, and FIS report for your community have been completed, certain additional requirements must be met under Section 1361 of the National Flood Insurance Act of 1968, as amended, within 6 months from the date of this letter. Prior to May 20, 1996, your community is required, as a condition of continued eligibility in the National Flood Insurance Program(NFIP), to adopt or show evidence of adoption of floodplain management regulations that meet the standards of Section 60.3(d) of the enclosed NFIP regulations (44 CFR 59, etc.). These standards are the minimum requirements and do not supersede any State or local requirements of a more stringent nature. It must be emphasized that all of the standards specified in Section 60.3(d) of the NFIP regulations must be enacted in a legally enforceable document. This includes adoption of the effective FIRM, FBFM, and FIS report to which the regulations apply and the modifications made by this map revision. Some of the standards should already have been enacted by your community. Any additional requirements can be met by taking one of the following actions: 1. Amending existing regulations to incorporate any additional requirements of Section 60.3(d); 2. Adopting all of the standards of Section 60.3(d) into one new, comprehensive set of regulations; or 3. Showing evidence that regulations have previously been adopted that meet or exceed the minimum requirements of Section 60.3(d). Communities that fail to enact the necessary floodplain management regulations will be suspended from participation in the NFIP and subject to the prohibitions contained in Section 202(a)of the Flood Disaster Protection Act of 1973 as amended. In addition to your community using the FIRM, FBFM, and FIS report to manage development in the floodplain, FEMA will use the FIRM and FIS report to establish appropriate flood insurance rates. On the effective date of the revised FIRM and FIS report, actuarial rates for flood insurance will be charged for all new structures and substantial improvements to existing structures located in the identified SFHAs. These rates may be higher if structures are not built in compliance with the floodplain management standards of the NFIP. The actuarial flood insurance rates increase as the lowest elevations (including basement) of new structures decrease in relation to the BFEs established for your community. This is an important consideration for new construction because building at a higher elevation can greatly reduce the cost of flood insurance. To assist your community in maintaining the FIRM and FBFM, we have enclosed a Summary of Map Actions (SOMA) to document previous Letters of Map Change (LOMCs) (i.e., Letters of Map Amendment, Letters of Map Revision)that will be superseded when the revised FIRM and FBFM panels referenced above become effective. Information on LOMCs is presented in three categories: (1)LOMCs that have been included on the revised FIRM and FBFM panels; (2) LOMCs that are too small to show on the revised FIRM and FBFM panels because of scale limitations; and (3) LOMCs that have not been included on the revised FIRM and FBFM panels because they are being superseded by new, detailed flooding data. 3 If you have any questions regarding the necessary floodplain management measures for your community or the NFIP in general, we urge you to contact the Director, Mitigation Division of FEMA in San Francisco, California, at(415)923-7177. If you have any questions concerning mapping issues in general or the enclosed SOMA, please contact Mr. Karl Mohr of our staff in Washington, DC, either by telephone at (202) 646-2770 or by facsimile at (202) 646-4596.

These LOMRs and LOMAs will remain in force until the revised FIRM becomes effective. To keep the LOMRs in force after the FIRM becomes effective, the community will need to request that the LOMRs be reissued. To keep the LOMAS in force after the FIRM becomes effective, the affected property owner(s) will need to request that the LOMAs be reissued. Upon the receipt of the request from the community or the property owner(s) , the LOMRs and LOMAs will be reissued free of charge by the Federal Insurance Administration.
