watermain is shown to. cross townhouse lots. Information on the locations of utility
easements must be provided for review to assure compliance with Joint Powers'
requirements for watennain location.
· The plans show water service line curb stops to be located within 3 feet of driVeways at Lots
3,4, & 7, Block 3, and Lots 5 & 17, Block 1. These services should be moved so that the
curb stops are at least 3 feet from the edge of the driveways.
· The plans appear to show the curb stDp!j; Qf1 the lot property lines. Thera is no note or detail
on thepfan$ shO\Ning' the Board's requirement that curb stops be iOiatedat least 1 foot from
lot property boundaries or easement boundaries. A note should be added to the plans to
make this requirement claar to the contractor, in addition to submitting a plat showing the
easements as required above.
· The specifications for this project contain standard details for installing water services for
both Joint Powers Water Board and the City of Albertville, and these standards are in
conflict. A note should be added to the plans referencing the Joint Powers Standards and
details in the specifications, and stating the Joint Powers standards always apply where
more stringent. .
· Board Design Standards require hydrants at the end of dead-ends for flUShing purposes. A
temporary hydrant should be added to the end of the 12" stub ending north of Co. Hwy. 37.
Based on the items listed above, we do not recommend approval of the plans for Karston Cove
until corrections are made. If you have any questions, please call me.
