Jurisdiction. These regulations shall apply to all land located within the City of Excelsior Springs.
Purpose And Intent. The /U Underground Overlay District is established for the following purposes:
[R.O. 2012 §408.020; Ord. No. 12-03-04, 3-5-2012]
The /U District may be established when either of the following conditions exists:
The /U zoning classification may be established, amended or removed only in accordance with rezoning procedures of Chapter 400. The only difference is that the /U District provisions apply only to the subsurface area and do not affect the zoning classification of the land surface above the /U District.
The initial designation or amendment must be accompanied by a certified survey map showing the extent of existing underground mining, the extent of proposed underground mining, and all points of access to the surface, whether vehicle entrances, pedestrian entrances, or openings for utility or ventilation.
[R.O. 2012 §408.030; Ord. No. 12-03-04, 3-5-2012]
The following uses are permitted by right in the /U Underground Overlay District:
Any use permitted by right, permitted by right with minimum use standards, or by special use permit in the zoning district controlling the surface property at the primary entrance (that having the most traffic) to the underground space is permitted in the /U District.
When not allowed by the surface zoning classification, extraction may be allowed by special use permit in accordance with Section 400.230.
Other allowed uses may be allowed in the subject /U District by the City Council at the time the /U District is established, provided that such use is not otherwise prohibited by other relevant City ordinance.
[R.O. 2012 §408.040; Ord. No. 12-03-04, 3-5-2012]
Underground space in the /U District is subject to the following standards and requirements:
Building permits are required to develop a habitable underground building and to qualify for a certificate of occupancy.
Access to underground uses must be by means only of non-residential zoning districts. Access to underground uses must be through property owned by or controlled by operators of the underground space. Such access must connect immediately to a major thoroughfare without first proceeding through or by other properties; or such entrances must be on property properly zoned to contain the uses developed within the underground space.
In order to qualify for building permits or certificates of occupancy, the owners or operators of underground space must have on file with the City a certificate by a registered professional engineer regarding the structural integrity of the underground space. Such certificate may provide for exceptions or conditions that apply as a condition of building permit approval.
All above ground ventilation equipment and utility installations must be screened from view of streets and adjacent R-zoned lots by landscaping or structures that are architecturally compatible with surrounding development.
