Rivers End Neighborhood Association Subdivision (RENA)
Boise River Annexation and Rezone - City of Eagle UPDATE
GEESE, GEESE, GEESE---WHAT CAN WE DO? SEE BELOW!
1. In the last year, the Association did extensive research, (phone calls and on-line) into how to remedy the problem. Geese are normally migratory but in moderating climates, such as Boise, they tend to remain in the area throughout the year and their lifetime. When this happens, the natural life cycle is to remain in and return to the immediate area where they were born or hatched. Our habitat, especially along Island Woods Drive and Ponds 6 and 9, includes mildly sloping terrain to access and enter the water. This feature enables the geese to move freely over and around common areas and sidewalks. Other ponds in the sub-division with steeper terrain and more extensive vegetation growth along the banks harbor fewer geese. Our properties provide shelter from hunters and most natural predatory animals. The geese find it easy to roost here overnight after feeding on numerous farm lands around us that have ample food.
2. Chemical treatments have limitations based on environmental issues and silhouetted predator decoys seem to have no effect. Boise Parks and Recreation have started to chemically neutralize the eggs that are laid in spring to help break the “return to where you were born” cycle. This is having some positive effect in the city parks but is not always popular with some residents of Rivers End who want to see the baby geese hatch and develop as a natural process of nature. Another possible option is using simulated firearms noise but the result according to wildlife experts is just temporary and not popular with homeowners in residential areas.
3. One approach that seems to have the most favor and success among the experts is using live “predators” such as dogs to continually harass and scatter the geese until they decide to move on. This approach has promise for our sub-division but how do we pay for such an activity and who and how often would it need to be done to have an effect. Working this is truly a “black hole and money pit.” However if any homeowners are aware of methods that have worked in other areas please let DSI know.
INFO ON VEGETATION CLEAN-UP/POND TREATMENTS - 20 AUG 15
The pond ecosystems are quite temperamental and conditions vary by season and weather. NC Services treat our ponds with necessary animal and child safe chemicals to keep algae and bottom vegetation to a minimum. Special handling is done on pond 8 & 11 because they are the irrigation source.
RIVERS END PRESSURIZED IRRIGATION--SYSTEM INFO update
There are five (5) pumps in the vault. Three (3) pumps for the irrigation system and two (2) to provide water for the entry water feature which are not connected to the irrigation system.
Irrigation pump one (1) is a small jockey pump that keeps a minimal pressure in the system when the demand is basically static (no down line demand for water).
Irrigation pump two (2) is a twenty five HP pump that is set to provide 80 PSI water to the system. It is controlled by a VFD (variable frequency drive) that sends a signal to irrigation pump three (3) when demand on the system exceeds the output of pump 2.
Irrigation pump three (3) is a duplicate of pump two and when activated by the VFD (about a five (5) PSI differential) comes on to keep the system pressure in that 80-85 PSI range.
Pressurized water is routed from the pumps to the system filter (installed about 3 years ago). The filter is self cleaning and runs its cleaning cycle anytime there is a 5 PSI differential between the water coming in and going out to the down line system. Down line system pressure will probably drop a few PSI during the filter flush operation. Based on the cleanliness of the water coming into the vault this flush operation will happen numerous times a day. The filter screen in this system filter is smaller than most filters that are installed when the water enters the homeowner’s property. This should filter out most particles but does not keep biological growth from occurring in the down line systems.
Routine homeowner maintenance of their irrigation components is a must to keep the system operating efficiently. This means routine cleaning of the main filter, drip line filters (if installed these have finer mesh than your main filter) and individual filters that are part of the sprinkler head itself.
If you observed the inadequate pressure to run your system, try the following:
Check and clean all filters. Remember if they are catching debris or biological growth they are doing their job.
Make sure you are only running one zone of your system at a time.
Adjust the time of the day you water. When the common areas are being watered there is a maximum demand on the system. Popular watering times seems to be between 4:00AM and 8:AM. This is another time of maximum demand on the system so changing from this time might help.
Remember there are 114 homeowners properties and all the common areas in our system requiring irrigation so staggered watering by homeowners has a positive effect Coordination between the Association and the Landscaper is also necessary to minimize excessive demand on the system.
One final note: Be sure to have your sprinkler system blown out in the fall once the irrigation is turned off or you elect to isolate your system from the subdivision system. If you don’t there could be component damage from freezing or residue/algae that gets trapped in your system.
