2012 Irrigation Plan
The following changes were proposed based on meeting with the DES
representative Derek Bennett:
The landscapable area is approximately 5.35 acres or 241,092 sq. ft.
We should address and reduce the irrigated areas, such as, reducing the
amount of irrigated lawns. We could also replace lawn with wild flower
meadow, native plantings, etc. Reduce the watering schedule to twice a
week for each station. Eliminate the watering of lawn in back of units
except on top of the hill at station #6. Treat the topsoil with compost and
compost tea applications. Aerate the lawn to allow moisture and nutrients
to penetrate where needed. Raise the mower height to about 3 inches.
Install smart controllers to irrigate based on soil moisture and not the time
settings on the controller. Adjustment could be made to the controller
based on the fact that different zones require different water requirements
based on soil content, sun exposure, shade, etc. Install rain gages to
monitor amounts of rainfall. Establish a committee to monitor and manage
the irrigation system.
Sprinkler System Information
The sprinkler system taps off the main 6” cast iron water supply in 3 locations. One is on the corner of
Hadleigh and Blackburn Roads. One is between the pump house and 19 Hadleigh. One is on Flat Rock
halfway between Hadleigh and 27 Flat Rock.
At each of these 3 locations there is a “ball valve” located under a fiberglass cover. These “ball valves”
shut the water off to the station valves located behind several houses.
Station valves are also located under green fiberglass covered boxes. These station valves are controlled
by a “Hunter Box” or “controller” attached to the following addresses: 23 Flat Rock, 10 Hadleigh, 25
Hadleigh, 36 Hadleigh, 25 Hadleigh and the pump house. These controllers are programmed to turn the
stations on and off at specified times. Each station has from 3 to 9 sprinkler heads attached.
There is a battery operated moisture sensing transmitter that is attached to the eaves of the house that
the controller is attached to, and sends signals to the controller. This sensor will disable the sprinklers
during and shortly after a rain storm.
All sprinkler plumbing is buried only a few inches below the surface of the lawn and would freeze in the
winter if not drained.
Between the main water supply and the “ball valve” there is a shut off valve deep below the frost line,
which shuts off the water going to these “ball valves” so the sprinkler system can be drained for the
winter.
