Subject: Crooked Creek Peer Review of Biological Resources Assessment and Tree
Report
Below is a link to ESA’s Biological Letter report that includes a peer review and updated
information for the tree impacts. Please use this information to begin including the appropriate
number and type of trees within the project site as well as somewhere offsite. Based on the
assessment, the habitat that will need to be replaced includes 0.01 acre of California walnut
groves. The number of trees that will be removed includes 4 coast live oaks and 62 California
walnuts. Based on the City’s tree ordinance which is a 3:1 replacement, the project will be
required to plant 12 coast live oaks and 186 California black walnuts.
Please note that the Biological Letter report includes the version of the site plan that we
currently have. We understand that the site plan will be revised to, at a minimum, remove the
maintenance access road from behind the existing residences located along Crooked Creek
Drive. The tree and habitat assessment was based on the maintenance road behind the existing
residences would be removed.
The report is 19MB and as a result we have provided you the following link for access:
