Permitting
 You or your moving contractor will have to obtain permits to move the house on public roads or other rights-of-way. These permits may be required by local governments, highway departments, and Eliminate Mold And Mildew On Basement Walls utility companies, not only in the jurisdiction from which your house is being moved, but also any jurisdiction the house will pass through.
 
If the moving route crosses or affects private land, you may need to obtain the approval of the landowner. Obtaining the necessary permits and approvals may be a lengthy and complex process, and you may find that the requirements vary from jurisdiction to jurisdiction Eliminate Mold And Mildew On Basement Walls and agency to agency. So it is extremely important that you, your design professional, and your moving contractor investigate the need for permits and approvals early in the relocation process.
 
You or your design professional should check with local officials to make sure that when your house is moved to the new site, it will conform to all zoning requirements and building codes in effect at the time of the relocation. The design professional should also Eliminate Mold And Mildew On Basement Walls determine the local design standards and permitting requirements that govern the development of your new site. All permits required for construction at the new site, for moving your house, and for restoring the old site after the house is moved should be obtained before the relocation project begins.
 
 Preparing the New Site
 Before the house is moved, the new foundation is Eliminate Mold And Mildew On Basement Walls designed and is usually partially constructed. The foundation will be completed after the house is brought to the site. Clearing, excavation, and grading are necessary to allow construction to begin and to ensure that the house can be maneuvered on the site. Also, utility lines must be brought into the site so that there will be no delay in connecting them to the house and making it habitable.
 
Lifting the House
 In general, the steps required in lifting a house off its foundation are the same as those described in Chapter 5 for elevating a house on extended foundation walls. As described in Chapter 5, the steps for houses on basement and crawlspace foundations differ from those for houses on slab-on-grade foundations. Houses on basement and crawlspace foundations are separated from their Eliminate Mold And Mildew On Basement Walls foundations and lifted on steel I-beams that pass through the foundation walls directly below the floor framing.
 
The lifting is done with hydraulic jacks placed directly under the I-beams. The process for houses on slab-on-grade foundations is similar. However, because these houses are lifted with the concrete floor slab attached, the I-beams are inserted below the slab. Moving the House - After the house is lifted, the moving contractor performs whatever grading and excavation are necessary to create a temporary Eliminate Mold And Mildew On Basement Walls roadway that will allow the house to be moved to the street.
 
The area beneath the house must be leveled and compacted so that trailer wheel sets can be placed under the house (see Figure 7-2). The wheel sets and lifting beams form the trailer on which Eliminate Mold And Mildew On Basement Walls the house will be moved. The timing of the move may be critical in areas with heavy traffic during morning and evening rush hours. In these areas, houses are often moved late at night or early in the morning.
 
 After the wheels are attached, a tractor or bulldozer tows the house to the street. As the house is being moved, workers continually block the wheels to prevent sudden movement. At the street, the house is stabilized, the trailer is attached to a truck, and the journey to the new site begins. Eliminate Mold And Mildew On Basement Walls At the new site, the moving contractor positions the house over the partially completed foundation and supports the house on cribbing so the trailer wheels can be removed.
 
As in the house elevation process described in Chapter 5, the house is lifted on hydraulic jacks to the desired height and the foundation is completed below it (see Figure 7-4). The house Eliminate Mold And Mildew On Basement Walls is then lowered onto the foundation, all utilities are connected, and any necessary backfilling and landscaping is completed. Restoring the Old Site After the house is moved, the old site must be restored according to the requirements of local regulations.
 
 Restoring the site usually involves demolishing and removing the old foundation and any pavement, such as a driveway or patio; backfilling an old basement; Eliminate Mold And Mildew On Basement Walls removing all abandoned utility systems; grading to restore areas disturbed by demolition; and stabilizing the site with new vegetation. Permits are normally required for demolition, grading, and vegetative stabilization. If your old site included a septic tank or fuel storage tank, you may have to meet the requirements of environmental regulations aimed at preventing contamination of the groundwater.
 
Depending on the age and condition of the tank, Eliminate Mold And Mildew On Basement Walls you may be required to drain and remove it. If it is an underground tank, you may have to drain it and anchor it to prevent flotation. You may also be required to test the soil around an underground tank to determine whether leakage has occurred. As the homeowner, you will usually be responsible for cleaning contaminated soil if there has been any leakage from the tank.
 
 In this situation, you will need the services of a qualified geotechnical or environmental engineer. Local utility companies or regulatory officials can inform you about requirements concerning capping, abandoning, or removing various utility system Eliminate Mold And Mildew On Basement Walls components. Dry floodproofing is completely sealing the exterior of a building to prevent the entry of flood waters. Unlike wet floodproofing (Chapter 6), which allows water to enter the house through wall openings, dry floodproofing seals all openings below the flood level and relies on the walls of the house to hold water out.
 
Because the walls are exposed to flood waters and the pressures they exert, dry floodproofing is practical only for houses with walls constructed of flood-resistant materials and only where flood depths are low (no more than 2 to 3 feet). Successful dry Eliminate Mold And Mildew On Basement Walls floodproofing involves the following:
 • sealing the exterior walls of the house
 • covering openings below the flood level
 • protecting the interior of the house from seepage
 • protecting service equipment outside the house
 
The following sections discuss the most important considerations regarding dry floodproofing and describe the modifications that must be made to a house as part of a dry floodproofing project. Protection of service equipment is discussed in Chapter 8. Eliminate Mold And Mildew On Basement Walls Dry floodproofing cannot be used to bring a substantially damaged or substantially improved house into compliance with the requirements of your community’s floodplain management ordinance or law.
 
DEFINITION Service equipmentincludes utility systems, heating and cooling systems, and large appliances. For additional information about dry floodproofing techniques, refer to Federal Eliminate Mold And Mildew On Basement Walls Emergency Management Agency (FEMA) Technical Bulletin 3-93, Non-Residential Floodproofing – Requirements and Certification for Buildings Located in Special Flood Hazard Areas, and FEMA 259, Principles and Practices for Retrofitting Flood Prone Residential Buildings.
