Subject: Oak Park Senior Living - Tree Replacement Requirement
OPH Staff -
I have reviewed the files re: Oakgreen Village and Oak Park Senior Living (phases I and II) in order to calculate the tree
replacement requirement for the latter portion of the PUD.
Per my email report to OPH Staff 5 /4/06 (based on Oakgreen Village development plans dated 4/26/06) there was a
final tree replacement requirement for a large portion of the PUD development of $18,500..
According to city records, this amount was paid 9/7/06.
The tree removal plan for Oak Park Senior Living showed many of the same trees, but the tree numbers for most of
the trees had been changed from the original tree inventory and plans. Tree removal for Oak Park Senior Living had
been calculated by the engineering company as tree removal independent of the original tree removal plans for most of
the parcel when Oakgreen Village plans were going forward. In actuality, a number of the trees indicated to be removed
for Oak Park Senior Living had already been included in the tree removal and replacement calculations for Oakgreen
Village.
Since these development projects (Oakgreen Village and Oak Park Senior Living phases I and II) are different phases of
a PUD, only trees which were indicated to be preserved in the previous plans, but are being removed for the later
phases, would need to be included in the tree replacement requirement calculations for Oak Park Senior Living phases I
and II.
To calculate the tree replacement requirement for Oak Park Senior Living (phases I and II)1 have taken information on
tree removal in these phases from the development plans for Oak Park Senior Living (phase I), dated 6/1/09, and Oak
Park Senior Living (phase II), dated 4/26/12. The tree replacement requirement for Oak Park Senior Living (phases I and
II) is 777 diameter inches of replacement trees. Since the PUD as a whole removed greater than 1500 in. of trees,
according to the OPH Tree Protection Ordinance 1307, "woodland type factors" may be used to modify the diameter
inches of tree replacement required. Since the trees removed are mainly softwood deciduous and evergreens, with a
few hardwood species, the tree replacement requirement is reduced to 501 diameter inches of replacement trees.
The tree replacement inches planed in the landscape for Oak Park Senior Living (phase I) is 86.5 (Arborist email
report to staff dated 12/1/11). Estimated diameter inches of trees to be planted as part of landscaping for Oak Park
Senior Living (phase II) is 145 in. (p.c. Todd Erickson FFE 5/9/12: 20, 6 -8 ft. evergreens (est. ave. trunk diameter
3.5 in.), and 30, 2.5 in. deciduous trees). This landscaping credit
(231.5 in.) for phases I and II) brings the tree replacement requirement down to 269.5 diameter in. of replacement trees
x $50. /diameter in. = $13,475.. (Tree Replacement Requirement for Oak Park Senior Living I and II (cash in lieu of tree
planting)).
In development plans for Oak Park Senior Living, townhomes are indicated to be built north of the existing
townhomes (part of Oakgreen
Village) which are west of Oak Park Senior Living phase I and just south of the trail under the power lines. If this occurs,
trees on the berm north of those existing townhomes will be removed. These trees were planted to satisfy landscaping
and tree replacement requirements for Oakgreen Village. If removed, the trees (48 deciduous and evergreen trees
which equal 165 diameter in.) will need to be replaced or cash in lieu of tree planting paid: 165 diameter in. x
$50. /diameter in. = $ 8,250.. This amount would be offset by any trees planted in the new development area in that
future phase of the PUD, and would only be collected if the trees on the berm are removed in the future.
Please contact me if you have any questions regarding this review of tree removal /replacement for Oakgreen
Village /Oak Park Senior Living (phases I and II)
