1. Automatic underground irrigation system will be designed and installed by a licensed
contractor in grassy swale. System should be temporary to be removed after vegetation
is established.
2. Because of construction compaction of soil, completely clean area of construction
debris and heavily amend shrub beds with a three to six inch layer of compost. Till
entire area to a depth of 12".
3. Special care should be taken before planting trees. Excavate area to a depth of
24" and twice the size of the root ball. Heavily amend site with compost.
4. Swale areas should be clearly marked before site work begins to avoid soil
disturbance and compaction during construction. No vehicular traffic, except that
specifically used to construct the facility, should be allowed within 10 feet of swale
areas.
5. After swale areas are cleared and graded, all disturbed subsoil shall be tilled before
capping with 18" of topsoil. If existing areas surrounding the stormwater facility are
disturbed by construction, the top 18" of shall be tilled. After tilling is completed, no
other construction traffic shall be allowed in the area, except for planting and related
work.
6. Apply 2" pea gravel to bottom of swales to provide soil stabilization. 3" of bark
mulch shall be applied to swale side slopes.
7. Use only shrubs and varieties, as indicated on plan. Changes must be approved by
designer.
8. Purchase healthy material at minimum sizes indicated on plan.
9. Placement of shrubs and trees should match design as closely as possible. Minor
adjustments in plant spacing is acceptable.
10. Plant quantity should be based on planting plan, not plant list.
11. Designer is not responsible for plant failure.
12. Provide 3" of shredded bark mulch over planting beds.
