Landscaping

Planting trees

When you dig and see the cable line underneath call 811 to get help. The minimum depth for water, power and gas lines is 2’. Power lines can easily traced all the way to the meter with a metal detector. It doesn't work for water lines because there is no metal in the pipe to trace.

Privacy Trees

Arborvitae are very easy to maintain in the Pacific Northwest.

Some trees may grow very big in a few years potentially interfering with power lines, roofs, foundations, and other structures. The tree roots could also ruthlessly aggressive, and mess up drainage (like sewer pipes).

Lawn

Artificial Lawn

Artificial lawns have a few pros as below.

  • Looks nice
  • No maintenance - no watering or mowing is required.
  • Money on buying mower, fertilizer, weedkiller and so on is saved
  • Good drainage
  • Playing sports will not damage the grass

Artificial lawns have a few cons as below.

  • The upfront cost is very high.
  • It is not real grass so you can't get the smell of freshly cut grass
  • It has a lifespan of 10-25 years

Irrigation System

You might need to do a backflow testing for irrigation system since the non potable water may backflow and mix with the public potable water supply. There is a RPPB (Reduced Pressure Principle Backlog) assembly installed between the clean and non potable system – e.g. between the domestic water and the sprinkler system. The RPPB component has to be tested once a year to make sure that they are still effective. Otherwise the public water supply may be shut off. The testing can be done by a local contractor for tens of dollars.


Backyard Play Set

Make sure to contact your HOA or city about the safety codes. e.g. it may require the woodchips to be 1 foot deep (compacted) and the woodchip area must extend 2x the height of the swings in all directions.
