DRAINAGE REPORT
SUNSTONE SWALE AT
COLLINDALE BUSINESS PARK
PREPARED FOR
K. BILL TILEY
STEWART & ASSOCIATES, INC.
LOCATION
This project is located between the west line of Timberline Road and 300
feet east of Timberline Road, and lies between Fox Meadows Business Park
and Sunstone Village. The site is located within the Fox Meadows Basin.
EXISTING CONDITIONS
At present the Sunstone Swale is constructed to approximately 300 feet
east of Timberline Road. This construction was a part of the Sunstone
development.
Bob Shields has a pipe line and irigation water which is combined with
the storm water system in this area. The Shields' water arrives at the
site by two routes. One comes under the Collindale Golf Course and and
railroad, then in an open ditch to Timberline Road, then under Timberline
in a 24 inch concrete pipe. This pipe junctures in a box on the east side
of Timberline with a 42 inch pipe from the south and a 21 inch outflow
pipe to the east. This entire system belongs to Shields and we propose
to not interfere with it. The second route is from the Chandler sump under
the Chadwick property in a 12 to 15 inch tile. This ties into the 42 inch
pipe on the east side of Timberline Road just north of Caribou. Shields'
water then flows north in the 42 inch pipe to the existing junction box,
and then east in Shields' 21 inch pipe.
PROPOSED CONSTRUCTION
Collindale Business Park and the South Collins Tech Center are located
on the west side of Timberline Road, and the allowable outflow from these
two developments must be carried under Timberline Road to the Sunstone
Swale. We propose a new 24 inch crossing under Timberline which will tie
into the existing 42 inch pipe at a new division box. This box is to be
constructed on the 42 inch pipe and a restriction plate shall be placed
on the north outlet to allow a calculated flow quantity into the Shields'
system. The additional storm flows from the new 24 inch pipe from the
west and the 42 inch pipe from the south will be carried to the east into
the Sunstone Swale by a 48 inch pipe.
The Shields' quantity of water flow is calculated on the attached
calculation sheets.
Mr. K. Bill Tiley discussed the proposed plan with Mr. Cal Strobel on April
18, 1989. Mr. Strobel, who is a partner in the Shields' irrigation system
was satisfied with the intent and design. Mr. Tiley later called Bob
Shields, who said that if Cal Strobel was satisfied with the design, he
also would be satisfied.
The attached calculation sheets also show the sizing of the 24 inch Tine
along with the capacity of the swale.
