Increasingly, local jurisdictions are implementing policy to regulate the degree of severe storm protection that is mandatory in their communities. With this trend growing in the region, the Mid-America Regional Council (MARC) and the Metropolitan Emergency Managers Committee (MEMC) set out to examine the multitude of considerations that must be made as local jurisdictions approach this issue. Understanding that a number of disciplines could be potentially impacted by this type of regulation, MARC and the MEMC began with a thorough process of information collection. During the first phase of this process, surveys were conducted to gain an understanding of the current degree of regulation in the region. The results of those surveys are included in this report. MARC invited numerous stakeholders from the community to participate in a Hazard Mitigation Task Group. This group compiled and reviewed the information and feedback included in this document. The members of the Hazard Mitigation Task Group came from diverse backgrounds and represented many of the disciplines impacted by this type of regulation. Through work of the task group, we outlined many of the issues which local governments need to consider if they wish to regulate severe storm protection in their communities. These considerations are included in this report. There are strong cases to be made on both sides of the issue — public safety and economic viability — and costs and benefits must be weighed in each community. Through this document, the Hazard Mitigation Task Group hopes to provide planning guidance and consistent

  • Conditioned Crawl Space Construction, Performance and Codes
    building science.com © 2006 Building Science Press All rights of reproduction in any form reserved. Conditioned Crawl Space Construction, Performance and Codes Research Report - 0401 2004-11-02 by Joseph Lstiburek, Building Science Corporation Abstract: Conditioned crawl spaces perform better than vented crawl spaces in terms of safety, health, comfort, durability and energy consumption. Conditioned crawl spaces also do not cost more to construct than vented crawl spaces. Existing vented crawl spaces are experiencing serious moisture and mold problems and are costing builders and homeowners significant resources to repair. Despite the obvious problems with existing vented crawl spaces and the obvious benefits of conditioned crawl spaces there is not a significant trend towards the construction of conditioned crawlspaces. One of the reasons typically cited by builders and designers is “the code does not allow me to build unvented crawl spaces”. This is both generally correct and misleading. The model codes do not allow the construction of “unvented” crawl spaces – except in very limited circumstances, but they do allow the construction of “conditioned” crawl spaces. The distinction is important and necessary. Four conditioned crawl spaces were constructed and monitored over a 12-month period. The data is presented and used to support the current code requirements for the construction of conditioned crawl spaces.

  • Actions You Can Take to Protect a Flood-Prone House Or Business
    Actions You Can Take to Protect a Flood-Prone House or Business with a Crawlspace If your home or business has been flooded or is located in or near a flood hazard area, you typically have two choices: 1. Wait for the government to do something, like construct a reservoir or levee, or 2. Take actions on your own to reduce your risk of flood damage. This brochure is for homeowners and business owners who want to reduce their exposure to flood damage (and potentially lower flood insurance premiums). Even if a government agency is planning to construct a reservoir or other flood control project, it may take years before it is constructed and operational. Meanwhile, you may flood again. This brochure provides a step-by-step decision-making process that can help you to reduce flood risk. While it is advisable to consult with your local floodplain management administrator on regulatory and flood insurance requirements, this brochure is intended to provide basic flood risk reduction advice for structures located on a crawlspace. Step 1. Learn About Your Flood Hazard You may have been flooded in the past, but the next flood could be worse. Talk to your community’s floodplain management, planning, engineering or permit office and review any flood or drainage studies that have been done for your area. Answer these questions: a. How deep have past floods been? Don’t assume the last flood is the worst that can happen. You also need to answer the following questions. b. How deep could a future flood be? While your community staff won’t be able to make a prediction, they should have a Flood Insurance Rate Map and a Flood Insurance Study (FIS) that could tell you how deep different floods could be.

  • RH-12 - 1 May 2003 ACTIVITY: Tips for Wet Basements and Crawl Spaces RH – 12
    ACTIVITY: Tips for Wet Basements and Crawl Spaces RH – 12 WET BASEMENT AND CRAWL SPACE PROBLEMS, CAUSES AND REMEDIES -- TIPS FOR HOMEOWNERS AND HOME BUYERS The primary purpose of this BMP is to inform the homeowner, home buyer, and home builder about the usual causes for wet basements and crawl spaces, plus effective measures for preventing or correcting problems. This information can enable the public to build, select, or repair homes wisely. Although this BMP is not directly connected with water quality and stormwater pollution, the matter of wet basements and crawl spaces is closely related to stormwater design, This BMP is adapted from a booklet landscaping, and minimizing contact with stormwater. (original date - September 1997) by: Dr. Bruce A. Tschantz, P.E. UT Water Resources Research Center University Of Tennessee, Knoxville Immediate & Long-Term Problems Causes of Wet Basements and Crawl Spaces Preventing Wet Basements and Crawl Spaces Tips for Homeowners and Home IMMEDIATEBuilders AND LONG-TERM PROBLEMS Standing water or seepage inside residential crawl spaces and basements can cause frustrating problems for the homeowner. These problems can be both immediate and long-term. For example, standing water and mud inside crawl spaces make it very difficult and messy to gain access under the house for inspecting, maintaining, and servicing electrical circuits, drains and water lines, heating and air conditioning, and other utilities. Wet basements and crawl spaces are sources of high humidity, which can produce surface condensation, mildew and fungi, musty odors, and an unhealthly environment. Such moisture can cause deterioration of floor joists, beams, subflooring, insulation, and electrical-mechanical systems.

  • Conditioned Crawl Space Guide
    Abstract CONDITIONED Conditioned crawl spaces perform better than vented crawl spaces in terms of safety, health, comfort, durability and energy consumption. Conditioned crawl spaces also do CRAWL SPACE not cost more to construct than vented crawl spaces. Existing vented crawl spaces are experiencing serious moisture and mold problems and are costing builder’s and homeowners significant resources to repair. Despite the PERMIT GUIDE obvious problems with existing vented crawl spaces and the obvious benefits of conditioned crawl spaces there is not a significant trend towards the construction of conditioned crawlspaces. One of the reasons typically cited by builders and designers is “the code does not allow me to build unvented crawl spaces”. This is both generally correct and misleading. The model codes do not allow the construction of “unvented” crawl spaces – except in very limited circumstances, but they do allow the construction of “conditioned” crawl spaces. The distinction is important and necessary. Background Crawl space venting is generally viewed as good practice despite the obvious moisture problems that occur when outside air with a dew point higher than interior crawl space surface temperature is permitted to enter a crawl space. Unvented, conditioned crawl spaces with insulation on the perimeter solve this problem. Unvented, conditioned crawl spaces with insulation on the perimeter perform better in terms of safety and health (pest control), comfort (warm floors, uniform temperatures), durability (moisture) and energy consumption than passively vented crawl spaces with sub floor insulation. Perimeter insulation rather than floor insulation performs better in all climates from an energy conservation perspective. The crawl space temperatures, dew points and relative humidities track that of the house.
