lO-13h. Martin Marietta Materials (SU-24-02; SU-25-02; V-26-02; V-27-02)
Petitioner seeks Special Use approval of a Sand and Gravel Extraction Operation and an
Artificial Lake.
Petitioner seeks the following Developmental Standards Variances:
V-26-02 ZO 5.2.2: Other Requirements ISO-foot setback
V-27-02 ZO 5.2.2: Other Requirements 1 DO-foot setback
The site is located on the northwest comer of East 106th Street and Hazel Dell Parkway.
The site is zoned S-I/Residence - Low Density.
The proposed sand and gravel extraction operation will be conducted in a manner
similar to the operation currently underway to the east of the Kingswood Subdivision - a
floating dredge will remove material that would then be transferred to the processing
facility relocated on the east side of Hazel Dell Road. There is no underground mining
proposed with this petition.
The estimated life of the extraction operation is fourteen (14) years. The
operation will proceed in seven phases. the first three of which are located immediately
south of the Kingswood Subdivision. An eight-foot berm and additional landscalJe
plantings are proposed to minimize the disturbance to the abutting residents. In addition.
a six-foot fence will be placed to address safety issues.
Truck access to the site will be from the existing entrance on Hazel Dell Parkway.
and no access is proposed from East 106th Street.
Noise from the dredge itself is minimal. Trucks will utilize strobes during back-
up rather than an audible signal. Noise from the processing facility on the east side of
Hazel Dell Parkway will be handled in a manner identical to the way in which the
existing processing facility is addressed. The additional distance and existing vegetation
on the east side of Hazel Dell Parkway should serve to make the processing facility
significantly less of a noise disturbance than it is today.
Representatives from the City's mining consulting firm. Spectra. will be in
attendance to address specific issues related to this petition.
The Department is recommending favorable consideration of these petitions with
the following Conditions:
1. That the Commitments proposed by the petitioner be executed and
recorded.
2. That the petitioner submit specific Landscape Plans for the bufferyards
adjacent to the Kingswood Subdivision, and that approval of those plans
be delegated to the Director.
3. That the cross sections be revised to address the comments of the
Hamilton County Surveyor's Office and Hamilton County Soil and Water
Conservation District regarding the slope to the water's edge and the
provision of a safety ledge to a point five feet below the water's surface.
