Dear Mr. Cox:
I am writing as a follow-up to our conversation last week. You asked that I review the site
plan that you will be submitting to the City of Dublin for the proposed lot, tree impacts and the
requirements for tree protection. This letter summarizes my review and recommendations.
I have reviewed the Plot Plan for Lot 8 prepared by RMR Design Group, December 23, 2003.
The building pad is within about 1.5' of finished grade. Construction for the house is outside
the tree ddplines. The house and small deck were shown 5' to 15' beyond the driplines. The
house foundation is proposed as pier and grade beam and the deck will be on pier footings.
A 6" drain line will run parallel to the house, west to east, outside the driplines. The line will
extend from near the southeast corner of the house, through the trees and into the drainage
dissipater at the bottom of the lot. The line will be approximately 30' southeast of tree #340,
the largest coast live oak (Quercu$ agrifolia) on the site.
In my opinion the impacts depicted in the Plot Plan are well within the tolerance of the trees.
The trees will not require pruning for construction clearance. Fine grading and excavation for
the piers is a minor impact, if any. The project, as designed, will be insignificant to the health
and stability of the trees.
I recommend the following.
1. Fence the trees at the edge of the driplines to completely enclose the TREE
PROTECTION ZONE before the start of any construction. The fence should run across
the width of the lot. It is not necessary to fence trees on the downhill side, away from
all construction. Fence shall be 6 ff. chain link or equivalent as approved by the City.
The fence shall remain until all grading and construction is completed.
2. Where the 6" drain line enters the driplines place it on grade and secure it with
stakes. Do not trench for the line within the driplines.
Please contact me if you have any questions regarding my review or recommendation.
