b. The use and enjoyment of the property may be affected by aircraft noise, vibrations, fumes, smoke, dust, or fuel particles from aircraft operation.

c. The City of Aurora has required that noise mitigation construction techniques be employed in construction to mitigate the noise to which the property is exposed. The vendor certifies that the applicable noise mitigation measures have been installed as required.

d. The noise to which the property may be subject from aircraft operation may exceed 65 LDN, which is the maximum acceptable level set by the Federal Department of Housing and Urban Development for residential land use. (Applicable only if the property is located within the 65 LDN contour of the Buckley AFB Airport Influence District).

e. The involved property is located within an area that has been designated as an accident potential zone II. Such property may be characterized by high noise levels and accident potential resulting from aircraft operations. (Applicable only if the property is located within APZ II of the Buckley AFB Airport Influence District).

f. The involved property is located within an area that has been designated as an accident potential zone I. Such property may be characterized by high noise levels and significant accident potential resulting from aircraft operations (Applicable only if the property is located within APZ I of the Buckley AFB Airport Influence District).

g. The City of Aurora has required that noise mitigation construction techniques be employed in construction to mitigate the noise to which the property is exposed. The vendor certifies that the applicable noise mitigation measures have been installed as required.
