Memorandum
To: Joanne Purtsezova, Planning
From: Glenn Brooks, Engineering
Date: 14 May 2012
Subject: Verizon Wireless Tier 2 Site Modes, Vest Property (SDP201200025)critical slope waiver
request
The critical slope waiver request has been reviewed. The engineering analysis of the request follows:
Description of critical slope area and proposed disturbance:
This is a wooden mountain side above residences. The applicant is proposing a new site for a new tower to
replace an old wooden tower.
Areas
Acres
Total site
10,000 sf lease area on a 2.16
acre parcel (existing lease area is
382sf)
Critical slopes
638sf
Remainder of lease area
Critical slopes disturbed
638sf
100% of critical slopes
in lease area
Exemptions to critical slopes waivers for driveways, roads and utilities without reasonable
alternative locations:
To date, cell towers and equipment sites have not been considered utilities which are exempt from critical
slopes waivers.
Compliance with Zoning Ordinance 18 -4.2:
"movement of soil and rock"
Proper retaining wall construction, control of drainage, and vegetative stabilization will prevent any
movement of soil.
"excessive stormwater runoff'
Stormwater runoff has not been addressed, but the site is fairly small.
"siltation"
This site is small enough that it will probably not require an erosion control plan and inspection.
"loss of aesthetic resource"
Planning should speak to this concern.
"septic effluent"
This use has no sewage.
Based on the review above, there are no engineering concerns which prohibit the disturbance of the critical
slopes as shown. However, it is recommended that the equipment pad be moved down the slope out of the
critical area. If there is sufficient explanation to the Board as to why this cannot be done, engineering does
not have any concerns with impacts for this small site.
