Once airborne, asbestos fibers can stay suspended in the air for days, weeks or even months before settling out of the air, only to become airborne again from some minor disturbance, such as turning on an air conditioner. Uncontrolled asbestos abatement projects or renovation projects that disturb asbestos may cause latent asbestos hazards that could expose people to asbestos in the future, long after the renovation activity occurred. The airborne asbestos fiber concentrations resulting from disturbances may result in a significant exposure to the current and future occupants of the home. 1. Are you the owner/builder for this project? ___ NO ___ YES If YES, you must submit a Single-Family Residential Dwelling Area of Public Access Opt-out Form with the Colorado Department of Public Health and Environment (CDPHE). http://www.cdphe.state.co.us/ap/asbestos/asSFRDform.pdf A copy of this form must be submitted with the building permit application. Due to a rescinded EPA Ban, buildings of any age may contain asbestos; even those built after 1988 may have asbestos containing materials and therefore all demolition, remodel or renovation projects must determine if disturbed material above the trigger levels contains asbestos. 2. Residential: Will you be removing more than 50 linear feet or 32 sq.ft. or equivalent of a 55- gallon drum of any material besides concrete, wood, bricks or steel (examples are drywall, linoleum, carpet, ceiling tiles, pipe insulation, etc)? ___ NO ___ YES 3. Commercial: Will you be removing more than 260 linear feet or 160 sq.ft or equivalent of a 55-gallon drum of any material besides concrete, wood, bricks or steel (examples are drywall, linoleum, carpet, ceiling tiles, pipe insulation, etc)? ___ NO ___ YES 4. Will you be completely demolishing the building? ___ NO ___ YES If the answer is YES to either question #2, #3 or #4, you need an asbestos test before you can apply for a building and/or demolition permit. A state certified asbestos inspector must do this test and the test report must be submitted with the building permit application. If the building has asbestos, a state certified asbestos abatement firm must remove it. After removal, the abatement firm must provide a letter to the Building Division stating that all the asbestos has been removed and that the air is clean. This letter must be received BEFORE a permit will be issued. (See the local or statewide Yellow Pages for certified asbestos inspectors and abatement companies. ALWAYS ASK FOR PROOF OF CURRENT STATE CERTIFICATION.) If YES to question #4 and your asbestos test is less than the State Threshold, you must still submit a demolition permit with the CDPHE. http://www.cdphe.state.co.us/ap/asbestos/asdemo.pdf A copy of this demolition permit must be submitted with the building permit application. I hereby certify that the above information is true and complete.

Both parcels have the same owner. · Please refer to attached drawings D-101, D-102, A-101, A-102, A-104, and A-501 for areas of demolition and reconfiguration. Discussion of Drainage Issues: · Due to lack of as-built civil drawings, the foundation drainage and downspout system is assumed to drain to existing on-site drywells to be verified in field. Discussion of Drainage Alterations: · The proposed drainage of the lightwells will not tie into a foundation drain and will be made as a separate system to drain to an existing on-site drywell, the location of which shall be determined during construction. · The proposed drainage from the new stairs will be sheeted to drain over the existing driveway surface to the green landscape to the north. · Please refer to attached drawings A-101 and A-102. Discussion of Downstream Water Quality improvements: · By increasing the permeable area around the lightwell we are greatly reducing the amount of water directed to the drainage system from lightwells or the perimeter drain. · Sheeting our drainage of the proposed stairwell on the existing landscape reduces the amount of standing water on the hard surface of the driveway. Received 3/27/17 Verify where existing drywells are. The IBC does not allow surface drains being connected to the the foundation drain system.
