Memorandum
To: Amelia McCulley, Zoning Administrator
From: Glenn Brooks, County Engineer
Date: 11 Feb 2009
Rev. 1: 3 June 2009
Subject: Rivanna Quarry (CLE200900019)
Comments on original report of 11 -4 -08 by William Muncaster:
The Certified Engineer's Report for Rivanna Quarry has been reviewed. After reading this report, I am not
reassured that this use will meet the performance standards of the Zoning Ordinance. The engineer has
simply stated that, based on what his client has told him, he opines that they can meet the ordinance.
I found no specific information regarding the proposed operation, its location on -site, its hours of
operation, storage of materials, trucking of materials, maintenance of equipment, parking, safety measures
and precautions for the operation, etc. There has been no testing on -site for noise, vibration, or glare
concerns. This report contains only cursory statements based on un -cited references. Without
measurements taken, noise, vibration, and glare are likely to be concerns. Water pollution and erosion
issues on -site, both with existing areas and new operations do not appear to have been addressed.
Rev. 1: Updated comments on revised report of 5 -4 -09 by Timothy Miller
The updated report has been reviewed. I could find three new areas of prose in the updated report. Each
of these promises to do testing for compliance at a later time;
Noise: "Each time a new type of mobile rock crushing plant is brought to the property, the operator of the
quarry will conduct a noise study..."
Vibration: "...contractors will test for vibrations prior to the commencement of rock extraction..."
Glare: "Upon the relocation of a mobile plant to the site, the quarry operator will observe for glare, and
invite county inspectors out..."
It is my suggestion that this certified engineer's report be considered a phase 1 report, and conditionally
approved based upon a satisfactory phase 2. The phase 2 report shall be submitted to the county within 30
days of commencement of the operation, and shall contain the noise and vibration measurements and data
cited in this report, with an engineer's analysis for compliance and a seal.
