Document Description
Replace existing jail with new jail facility containing the following structures and facilities: -A main building that includes housing, control, administration, public lobby and visitation space, program space, medical/dental/mental health clinic, and intake area, as well as a detached kitchen building connected to the main building by a secure covered walkway, with free egress into a secure yard. The total interior area is approx. 20,360 sf. - Separate public and staff parking lots on the publicly facing side of the building (north side). - A secure yard on the secure side of the building (south side). - Vehicle sallyport attached to the main building intake and located on the west side of the facility with dedicated access from Twin Lakes Road. - Medical provider offices and a public lobby will be provided in the existing Twin Lakes Annex building. The old general hospital building will be demolished in order to accommodate the new jail structure. Demolition will occur according to applicable standards and regulations, such as permits and inspections by the Great Basin Unified Air Pollution Control District. The new construction, parking and driveways occur primarily on the footprint of the old general hospital building and/or pavement or hardened dirt used for parking and interior circulation. A small portion of the detached kitchen building (less than 1,900 sf) and some hardened surface for interior vehicle circulation will be constructed on existing irrigated turf. All of these surfaces are previously impacted. Proposed future uses shown on the site plan also occur on previously impacted surfaces, primarily on paved or hardened dirt surfaces currently used for parking, interior circulation, or as the helipad. Construction shall utilize best management practices to prevent impacts from run-off or dust, and stormwater management shall be incorporated into the site design. The proposed building is anticipated to have a maximum height of 25' and not exceed 35'. This height is similar to the old general hospital building to be demolished, and consistent with maximum allowable height of a single-family residence. Exterior lighting shall be dark sky compliant (Ch. 23 of the General Plan), and the complex oriented in such a manner that outdoor inmate presence and use is screened by the buildings and covered walkway from public uses (residential, school, public clinic use and parking) to the north and east. Potential Bi-State sage-grouse habitat will be protected by incorporation of applicable conservation measures as indicated in the General Plan Conservation/Open Space Element, particularly Action 2.A.3.e.
