<br /> and air quality. These concerns were addressed through the review process .
<br /> • Noise : To address noise concerns, the applicant provided a noise modeling study.
<br /> This modeling study measured existing noise levels at 3 separate locations for all of
<br /> the parameters listed in the LDR ' s , and then projected the plant ' s expected noise
<br /> levels based upon data from similar existing power plants. The study concluded that
<br /> the plant would increase noise at all three locations for all periods of measurement,
<br /> but will operate at noise levels that would meet the county ' s LDR criteria. It should
<br /> be noted that the closest residential development is Spanish Lakes Fairways , a
<br /> residential development in St. Lucie County, which is separated from the subject site
<br /> by a drainage canal right-of-way and significant vegetation . The closest unit in
<br /> Spanish Lakes Fairway, is approximately 400' from the subject site and
<br /> approximately 850' from the nearest structures on the Calpine Site. Please see
<br /> attachment #4 for the noise study.
<br /> • Odor : The applicant has indicated that natural gas will be the only fuel burned.
<br /> Based on the applicant ' s experience with similar types of operations , the applicant
<br /> has indicated that no unusual or offensive odors will be created .
<br /> • Aesthetics : Staff' s main concern regarding aesthetics is the "public view" of the
<br /> plant from I-95 , which is a main thoroughfare through the County. Presently, there
<br /> is a large number of native pines on the site. Staff will work with the applicant to
<br /> preserve as many of the trees as possible throughout the site. Tree preservation and
<br /> interior landscaping, in conjunction with the requirement of a Type "A" buffer along
<br /> the west property line, should provide an adequate visual buffer from I- 95 .
<br /> As previously indicated in the staff report, staff is recommending a Type "A" and
<br /> modified Type "A" buffer along the site ' s west property line adjacent to I-95 . At the
<br /> August 9th Planning and Zoning Commission meeting, the applicant expressed two
<br /> concerns regarding the recommended Type "A" buffer along the west property line.
<br /> The concerns relate to portions of the recommended buffer between I- 95 and a
<br /> proposed on-site retention pond and the portion of the Type "A" buffer that would
<br /> be located under the electrical tie lines which are proposed to run across I- 95
<br /> connecting the plant to the 230KV transmission lines .
<br /> For the buffer area between I- 95 and the retention area the applicant is concerned
<br /> that the minimum width of 30' necessary to create a Type "A" buffer may not be
<br /> available. Based on this concern, the Planning and Zoning Commission
<br /> recommended that the buffer be reduced to a Type "B " buffer which can be achieved
<br /> in a 20' width . In staff' s opinion, the applicant should be made to preserve and
<br /> provide the minimum quantity of landscape material for a- Type "A" buffer ( 12
<br /> canopy trees, 6 understory trees , and 30 shrubs per 100'), but be allowed a reduced
<br /> width, of no less than 20' ; if necessary . Such buffer details can be finalized during
<br /> the major site plan review and approval process .
<br /> The other area of concern that the applicant expressed at the Planning and Zoning
<br /> Commission meeting was the location of the recommended west buffer and
<br /> corresponding plant material to be located under the tie lines that connect the plant
<br /> to the 230 KV lines on the westside of 1-95 . The area where the tie lines cross could
<br /> create a wide window to the site if no buffering is required . Therefore , to ensure
