DEMOLITION PLAN REQUIREMENTS
FOR BUILDING DEMOLITION PERMIT APPLICATIONS FOR PROPERTIES NOT WITHIN SPECIAL FLOOD HAZARD AREAS
Application for a building demolition permit for improvements fitting the above description shall submit the following.
Two copies of a site demolition plan prepared by a professional land surveyor or engineer registered in the State of Illinois. The site demolition plan shall be based on a boundary survey prepared within the past year. The site demolition plan must be at an appropriate scale (e.g.: 1"=10', 1"=20’, or 1”=30”); reduced copies will not be accepted. The demolition plan must show ground topography and structure foundations by elevations and maximum one-foot contour intervals over the site and including all areas 100 feet beyond the site. Topographic information on the site and areas abutting or adjacent to the site must show existing drainage patterns and the drainage course that may affect, or be affected by the development of the site.
- The site demolition plan shall indicate and label all existing structures with dimensions, including setback distances to property lot lines.
- The site demolition plan shall show the location of all existing structures and land features abutting or adjacent to the site (sheds, garages, fences, etc.) including their top of foundation and finish grade elevation.
- The site demolition plan must show proposed grading of the lot as if it was to be restored to a vacant lot with no depressional area where an existing home’s basement was located. Drainage patterns or drainage courses shall be shown by depicting any changes in grade elevation by illustrating proposed (solid or bold lines) and existing (dashed or fine lines) contours and/or elevations (such as garage floors, swales, property corners, and property lines).
- The site demolition plan must show all other existing site improvements such as driveways, patios, and/or service walks and calls them all to be removed. This includes a note that states the existing drive approach is to be removed and any curbing restored at the end of the project.
- The site demolition plan must approximate the existing water service and call it to be removed from the main. (Temporary disconnects are allowed if a new building is to be started within 30 days, however, the demolition plan must state that the water service is to be removed at the main.)
- The site demolition plan must approximate the sanitary service and call it to be removed from the main including the wye. (Temporary disconnects are allowed if a new building is to be started within 30 days, however, the demolition plan must state that the sanitary service is to be removed at the main.)
- The site demolition plan must show a perimeter silt fence and provide detail.
- The site demolition plan must show temporary construction access and provide detail. It is allowable to use the existing driveway for this purpose which also removes the need for detail, however, it must then be called out as such on the plan.
- The site demolition plan must show an impervious area calculation to document the existing impervious on site before demolition. The calculation should follow the following example and be all impervious area that is on the property. (Note: For demolitions the Net New Impervious Area IS negative)
- Submit a tree preservation plan for all trees over six inches in diameter.
- Provide a traffic control and parking plan. The existing driveway should remain in place for construction access until the new driveway is constructed. This plan should limit contractor parking to one side of the roadway only. The traffic plan should indicate a truck route for delivery of material entering or leaving the site.
- Show the location of the portable toilet and material storage area.
- Indicate the required six-foot chain-link construction fence.
