Gather Site Data Page 15
On your Site Data Worksheet, enter a general description of the plants in each
hydrozone, such as “mixed ground cover and shrubs.” In some cases, this
information will come from the planting plan; in other cases, you will collect the
data from an actual site survey. Also, describe the planting density in each
hydrozone, this will strongly influence the selection of emission devices.
For each hydrozone, enter the irrigation method to be used. At this point, you
may simply want to distinguish low-volume hydrozones from other areas
requiring conventional turf rotors or spray heads.
Chapter 3 Review
To check your understanding of the material covered in Chapter 3, complete this
review. The review includes a description of a sample property, a plot plan of the
property (Figure 3-3) and a partially completed Site Data Worksheet (Figure 3-4).
Sample Property
For your convenience, we will be working with the same sample property
throughout this manual. A plot plan of the property can be found on page 16.
Refer to the Sample Plot Plan and read the description below.
Description
The sample property is the Doyle residence, located in Southern California. As
the plot plan shows, this wedge-shaped property contains a house and detached
garage. It also includes a concrete patio at the rear of the house, as well as a front
walkway and several concrete parking slabs. The north and west sides of the
house are surrounded by gravel walkways.
Hydrozones
As a preliminary design step, we have identified ten separate hydrozones on the
property. Hydrozones 1 - 4 are turf areas that will be irrigated by conventional
rotors or spray heads. Of course, we highly recommend quality Rain Bird rotors
and spray heads. Hydrozones 5 - 10 have been identified as low-volume irriga-
tion zones. They include the following:
Hydrozone 5 This hydrozone contains a single row of eight dwarf cypress
trees along the boundary fence.
Hydrozone 6 This hydrozone also contains a row of dwarf cypress trees
along the south fence.
Hydrozone 7 This hydrozone includes two irregularly shaped mixed
planting areas on either side of the front walkway. The
dominant plant is ground cover, along with two rows of
medium-sized shrubs, two ferns, and several smaller shrubs.
Hydrozone 8 This hydrozone includes a row of large shrubs planted
approximately 5 feet apart.
Hydrozone 9 This hydrozone has been reserved for a vegetable garden,
which is not yet planted.
Hydrozone 10 This hydrozone includes sparse plantings close to the
house and hanging and container plants on the front porch.
