Below are steps that should be taken to avoid a potential adverse impact of trees as they begin to grow in your yard:
Please contact the Washington Utility Notification Center at 811. This is a requirement of each homeowner mandated by Washington Law (RCW 19.122). Please do not excavate any soil until you are cleared by the appropriate underground utility authority.
Notify the HOA ACC.
Contact the Evergreen Pointe ACC by filling out an Architectural Control Committee Request Form (ACCRF). This is a requirement per the CC&Rs, Article 7.32. The ACC simply needs to know if you have complied with the first step and to understand the layout of your tree planting to ensure the position shall not compromise any existing community retaining wall, fence line, or underground storm drainage line.
Contact City of Olympia for Current Underground Pipe Location.
Planting trees should be avoided over the main directions of underground storm drainage pipes. These pipes usually run the length of the fence lines among adjacent lots and are buried about five feet beneath the top soil. Each home’s storm drainage runoff pipe (typically white) feeds into these larger, diameter storm drainage pipes (typically green). The City of Olympia Community Planning and Development Office can provide a detailed map of the underground pipe layout associated with any adjacent lots.

Know Your Soil Condition.
Whenever planting trees (fruit or decorative), homeowners must be mindful of the various poor soil conditions of Evergreen Pointe. The hardpan on lots may be reached at depths of 18 to 30 inches. As such, the growing roots will spread outward across the hardpan rather then borrow deep. Most likely, the roots over time will traverse across lawns and may adversely impact the foundation of homes. Additionally, trees planted near a fence may have roots traversing across the hardpan under the fence line and adversely impact adjacent lots.
Position of Tree Planting.
Recommendation for Tree Planting: Homeowners should project the eventual height and branch spread of trees by its 10th year. Recess the soil excavation site sufficiently from the fence line to compensate for the tree’s eventual growth and branch spread. Use an auger to dig deeply into the hardpan to avoid traversing root spread along the top of the hardpan.
