Overview

• District wide arboretums • Each year a new school will start an

arboretum project• Crescent Valley is the first to receive an

arboretum

Goals

• Educational tool• Aesthetically pleasing• Help decrease erosion of creek

Considered Sites

• East side of football field behind old bleacher location

• West lawn in front of gym, between the new indoor athletic facility, and the sidewalk to the gym

Chosen Site

Factors

• Compatibility with soil types• Coordination with existing structures,

plumbing, and power lines• Accommodation of student use of area• Potential to be used for instructional purposes• Time to mature • Potential to absorb runoff

Procedure

1. An initial meeting was held on with Cherie Stroud, Kim Patten, Craig Ellingson, Dave Eckert, Dan Bregar, and the AP Environmental Science student group. The design criteria for the arboretum were determined at this meeting.

Procedure (cont.)

2. Dave Eckert, proprietor of Willamette Watershed Productions and Virginia Village Productions, took the design criteria and formulated a concept design

Procedure (cont.)

3. A meeting was held on Friday, April 30th with Cherie Stroud, Dave Eckert, Kim Patten, Brad Probst , Jennifer Davis, Mrs. Cornell, and the AP Environmental Science student group. The concept design was reviewed and modified.

Procedure (cont.)4. Modifications included:

– Omit the design and planting of the Douglas-Fir Upland Forest. This will take way too much space than we can afford.

– Omit the design and planting of all herbs at this point.– Design and plant a small Bottomland Riparian area using

the plants on the list, with the exception of Black Cottonwood and Willow

– Design and plant a Oak woodlands with the exceptions of Doug-fir, Black Hawthorn, Introduced Cherry and Poison Oak

– Design and plant a small Rain Garden at the outfall of the drainage pipe from the batting cage building

Procedure (cont.)

5. Design was further modified by David Eckert 6. The renewed design was reviewed by the

APES students and finalized
