Planting Notes:
Native, white flowers, red berries
We recommend either a fall or winter planting. This will ensure a good plant establishment period during the cool and rainy
season. Since there is no irrigation, the ability to water during the first growing season will be crucial for landscape
success. Something as simple as a timer connected to a series of soaker hoses will go along way to contribute to the
success of this landscape. In addition, we would prefer the plant material to be container grown and be no larger than 1.5"
in caliper.
Construction Process.
1. Project approval/critical area permits
2. Remove all existing landscaping, dig out roots, and regrade
3. Top dress with 3 inches of compost
4. Purchase plant material for landscaping
5. Landscape installation
6. Top dress with 3 inches of wood chips

LANDSCAPE OBJECTIVE:
THE DESIGN APPROACH WAS TO CHOOSE PLANTS THAT ARE EITHER NATIVE OR HIGHLY ADAPTABLE AND NATURALLY FOUND IN
DRY OPEN WOODS, ROCKY SLOPES AND DISTURBED SITES. WE TOOK INTO ACCOUNT THAT IN THE FUTURE, OUR SUMMERS WILL
BE HOTTER AND OUR DRY SEASON WILL BE EXTENDED.

Notes
In the proposed additional planting area:
Keep the existing plants on the east side of the project
between the proposed area and the paved pathway.
This would include the existing ornamental cherries as
well as the sword fern along the upper gravel pathway.
Remove all other existing plant material.
