CONTROL STRUCTURE WITH STOPLOG CHANNEL, STOPLOGS, CONCRETE BASE, DRAWDOWN PIPE,

AND 12” CMP PIPE AS SHOWN ON THE PLANS. ITEM ALSO INCLUDES ALL EXCAVATION, PLACING, COMPACTING BACKFILL MATERIAL, AND PIPE CONNECTIONS AND ANTI-SEEP COLLARS REQUIRED FOR THE WATER CONTROL STRUCTURE ASSEMBLY, LABOR, AND OTHER MATERIALS NECESSARY FOR THE

INSTALLATION OF THE WATER CONTROL STRUCTURE ASSEMBLY.

23 IA-CS-051 TILE OUTLET

ITEM INCLUDES FURNISHING AND INSTALLATION OF THE 20 LF CMP TILE OUTLET, CONCRETE COLLAR, AND ANIMAL GUARD. TILE OUTLET PIPE SHOULD HAVE A MINIMUM GRADE OF 1%. THE OUTLET

INVERT SHOULD BE A MINIMUM OF 1-FOOT ABOVE THE NORMAL POOL ELEVATION IN WHICH IT IS

DRAINING INTO.

24 IA-CS-061 RIPRAP

MATERIAL SHALL COMPLY WITH GRADATION OF IOWA DOT SPECIFICATION 4130.02, CLASS E.

PAYMENT WILL BE FOR ACTUAL TONS PLACED BASED ON SCALE TICKETS.

25 IA-CS-061 GRANULAR FOUNDATION MATERIAL

INCLUDES FURNISHING, STOCKPILING, AND INSTALLING THE SPECIFIED MATERIAL. MATERIAL SHALL

MEET ASTM D2321 CLASS 1 (CRUSHED ROCK, ANGULAR). MATERIAL MUST BE CRUSHED AND

ANGULAR, ROUNDED PEBBLES, STONES OR "RIVER ROCK" WILL NOT BE ACCEPTED. ITEM WILL ONLY

BE PAID FOR RIPRAP/EROSION FILTER STONE AND HDPE DUAL-WALL PIPE BEDDING, UPON

APPROVAL OF ENGINEER. GRANULAR FOUNDATION MATERIAL USED FOR OTHER BID ITEMS, SUCH AS STRUCTURE FOUNDATION OR TILE CONNECTIONS, IS CONSIDERED INCIDENTAL TO THAT SPECIFIC BID

ITEM AND WILL NOT BE PAID UNDER THIS ITEM.

26 IA-CS-061 ROAD ACCESS DRIVEWAY

INCLUDES THE CONSTRUCTION OF A PERMANENT STABLILIZED DRIVEWAY AND CULVERT AS SHOWN

ON PLANS AND IN ACCORDANCE WITH FLOYD COUNTY SECONDARY ROADS. ITEM INCLUDES
