To: P&Z Board Members
From: Troy Jones
Re: Specific concerns raised by board members regarding the Rigden Farm ODP
Issue #1) Protection of existing tree groves:
A. Typically, groves of trees are not designated as natural areas unless they are
considered nesting sites for raptor birds.
B. Protection of existing "significant trees" are regulated in the LUC Section
3.2.1(F) Tree Protection and Replacement which protects them through the
following process:
• "Significant Trees" means any tree with a diameter at breast height of six
inches or more (according to the definitions in Section 5 of the LUC).
• All landscape plans at the PDP stage shall identify the locations, species,
size and condition of all existing trees each labeled showing the
applicant's intent to either remove, transplant or protect.
• Mitigation is required when it is not feasible to retain or transplant
significant existing trees.
• The City Forester appraises the trees to determine the required mitigation
ratio (1:1 to 1:6).
Issue #2) Minimizing the disturbance of topography due to cut and fill:
A. Unless the topography contains protected natural habitats and features, or has
significant rock outcroppings, the Natural Resources Department has no
regulations governing the disturbance of topography.
B. The Engineering Department has no engineering standards governing the
disturbance of topography.
C. The land use code does not have any regulations governing the disturbance of
topography in areas that are not specifically restricted by the LOD or the
buffer zones.
