This report was prepared under the National Program of Inspection of Non-Federal Dams. This report assesses the general condition of the dam with respect to safety, based on available data and on visual inspection, to determine if the dam poses hazards to human life or property. (Author).

The purpose of the inspection was to make an assessment of the general condition of the dam with respect to safety, based upon available data and visual inspection, in order to determine if the dam poses hazards to human life or property. Inspection and evaluation indicated the spillways do not meet the criteria set forth in the guidelines. The spillways will not pass the probable maximum flood without overtopping but will pass 20 percent of the probable maximum flood. The spillways will pass the flood which has a one percent probability of occurrence in any given year (100-year flood). The spillway design flood recommended by the guidelines is 50 to 100 percent of the probable maximum flood. Considering the hazard zone, the spillway design flood should be 100 percent of the probable maximum flood. The probable maximum flood is defined as the flood discharge which may be expected from the most severe combination of critical meteorologic and hydrologic conditions which are reasonably possible in the region. Based on visual observations, this dam appears to be in fair condition.

Union Lake Dam was inspected by a team of engineers. The purpose of the inspection was to make an assessment of the general condition of the dam with respect to safety, based upon available data and visual inspection, in order to determine if the dam poses hazards to human life or property. Our inspection and evaluation indicates the spillways do not meet the criteria set forth in the guidelines for a dam having the above size and hazard potential. The spillways will not pass the probable maximum flood without overtopping but will pass 10 percent of the probable maximum flood. The spillways will not pass the flood which has a one percent chance of occurrence in any given year (100-year flood), but will pass the flood with a 10 percent change of occurrence (10-year flood). The spillway design flood recommended by the guidelines is 50 to 100 percent of the probable maximum flood. Considering the damage zone, the spillway design flood should be 100 percent of the probable maximum flood.

Riss Lake Dam was inspected by an interdisciplinary team of engineers. The purpose of the inspection was to make an assessment of the general condition of the dam with respect to safety, based upon available data and visual inspection, in order to determine if the dam poses hazards to human life property. Our inspection and evaluation indicates that the spillway does not meet the criteria set forth in the guidelines for a dam having the above size and hazard potential. The spillway will not pass a 100-year flood (flood having a one percent chance of being exceeded in any year). The spillway will pass 12% of the Probable Maximum Flood without overtopping the dam. The Probable Maximum Flood (PMF) is defined as the flood that may be expected from the most severe combination of critical meteorologic and hydrologic conditions that are reasonably possible in the region.

The purpose of the inspection was to make an assessment of the general condition of the dam with respect to safety, based upon available data and visual inspection, in order to determine if the dam poses hazards to human life or property. This dam is classified as an intermediate size dam with a high downstream hazard potential. The inspection and evaluation indicates the spillway does not meet the criteria set forth in the guidelines for a dam having the above size and hazard potential. The spillway will pass 50 percent of the probable maximum flood without overtopping. Deficiencies visually observed by the inspection team were minor amounts of seepage at random slab, joints and in abutment drains, minor concrete spalling on the spillways downstream surface, exposed reinforcing steel on vertical supports, and the absence of containment walls on the spillway.

The purpose of the inspection was to make an assessment of the general conditions of the dam with respect to safety, based upon available data visual inspection, in order to determine if the dam poses hazards to human life or property. The inspection and evaluation indicate that the spillways do not meet the minimum criteria set forth in the recommended guidelines for an intermediate dam having a high hazard potential. The Probable Maximum Flood is the appropriate spillway design flood. The spillway will pass the 100-year flood (a flood having a 1 percent probability of being exceeded in any year) without overtopping the dam. The spillways will pass 22 percent of the Probable Maximum Flood without overtopping the dam. The Probable Maximum Flood (PMF) is defined as the flood that may be expected from the most severe combination of critical meteorologic and hydrologic conditions that are reasonably possible in the region.

FEMA's Hazard Mitigation Grant Program is a powerful resource in the combined effort by Federal, State, and local government, as well as private industry and homeowners, to end the cycle of repetitive disaster damage. The Robert T. Stafford Disaster Relief and Emergency Assistance Act was passed on November 23, 1988, amending Public Law 93-288, the Disaster Relief Act of 1974. The Stafford Act included Section 404, which established the Hazard Mitigation Grant Program. In 1993, the Hazard Mitigation and Relocation Act amended Section 404 to increase the amount of HMGP funds available and the cost-share to 75 percent Federal. This amendment also encouraged the use of property acquisition and other non-structural flood mitigation measures. In an effort to streamline HMGP delivery, FEMA encourages States to develop their mitigation programs before disaster strikes. States are adopting a more active HMGP management role. Increased capabilities may include: Conducting comprehensive all-hazard mitigation planning prior to disaster events; Providing applicants technical assistance on sound mitigation techniques and hazard mitigation policy and procedures; Coordinating mitigation programs through interagency teams or councils. Conducting benefit-cost analyses; and Preparing National Environmental Policy Act reviews for FEMA approval. States that integrate the HMGP with their frequently updated State Administrative and Hazard Mitigation Plans will create cohesive and effective approaches to loss reduction. This type of coordinated approach minimizes the distinction between “predisaster” and “post-disaster” time periods, and instead produces an ongoing mitigation effort. Hazard mitigation is any sustained action taken to reduce or eliminate long-term risk to people and property from natural hazards and their effects. A key purpose of the HMGP is to ensure that the opportunity to take critical mitigation measures to protect life and property from future disasters is not lost during the recovery and reconstruction process following a disaster. Program grant funds available under Section 404 of the Stafford Act provide States with the incentive and capability to implement mitigation measures that previously may have been infeasible. The purpose of this Desk Reference is to: Provide comprehensive information about FEMA's Hazard Mitigation Grant Program (HMGP); Increase awareness of the HMGP as an integral part of statewide hazard mitigation efforts; and Encourage deeper commitments and increased responsibilities on the part of all States and communities to reduce damage and losses from natural disasters. This Desk Reference is organized to simplify program information and assist the reader with practical guidance for successful participation in the program. Lists of program-related acronyms and definitions are included, along with appendices that amplify selected aspects of the HMGP. This Desk Reference is organized into 14 sections, each of which presents a major HMGP subject area. In each section, information is presented on the right side of the page. In several sections, job aids containing supplemental material are provided. The job aids for each section can be found at the end of the section. At the front of each section, there is a detailed table of contents to help you locate specific information.
