Yeah, I agree – thanks for the fittings tip.  Rainbird and another booster pump designer are telling me we can use a variable speed/ freq. drive pump with a pressure switch and this won’t require a controller to fire the pump…  Hope that is true.

Hi Tyson,

Thanks for the reply and info.  Yes, 2-wire or central control would be great and solve a lot of issues.  Just can’t get the old timers in this city on board with newer technology… Basically I have come to the same conclusion as you.  Have to design the system for worse case all (5) controllers running at the same time.  Need a dummy controller, w/ no stations, to cut off the whole system with a fs/mv.  However, I don’t feel this is necessary as someone will definitely notice a large main break!  I will do fs/mv at each sub poc/ controller and have to abandon the looped main in the park.

Yeah, thanks.  It was the City plan check that required it in the first place… Local ordinance is stricter that state model.

Toby – I totally agree with your comments.  This was for Santa Rosa, CA  – I believe the Sub-Meter is a way of not requiring a separate City Meter for Irrigation.  California’s Model Water Efficient Landscape Ordinance AB 1881 only recommends (§ 492.7) dedicated meters for landscapes smaller than 5,000 square feet – so this must be the city’s attempt to comply w/ the recommendation?

Thanks for the help/ comments!  Here is the product spec I ended up using:

1″ IRRIGATION SUB-METER:

NETAFIM WM-100-1.0-RS-M
(DISPLAY IN GALLONS FOR HOME OWNER)
INSTALL IN (1) #1419 CARSON BOX W/ LID

Thanks guys for replying.  Here is what I found in the ADAAG:

The question still remains…

what it are “Other Elements” and do bollards at a certain spacing qualify?

4.29.5 Detectable Warnings at Hazardous Vehicular Areas.

If a walk crosses or adjoins a vehicular way, and the walking surfaces are not separated by curbs, railings, or other elements between the pedestrian areas and vehicular areas, the boundary between the areas shall be defined by a continuous detectable warning which is 36 in (915 mm) wide, complying with 4.29.2.

3.5 Definitions: 

Detectable Warning. A standardized surface feature built in or applied to walking surfaces or other elements to warn visually impaired people of hazards on a circulation path.
