Prior to and as a condition of final acceptance of improvements, construction record drawings shall be prepared and submitted for review and approval.
Upon approval, construction record drawings shall be provided in the following formats:
A. Four (4) prints on bond paper;
B. An electronic file of the full set in Acrobat Adobe format; and,
C. An electronic file in AutoCAD 2010 (or newer) format on CD ROM or via e-mail to the address designated by the Village Engineer.
Provide only plan view drawing at preferred scale of 1" = 50'. Alternate allowable scales are 1" = 40', 1" = 30' and 1" = 20'. Multiple sheets shall be used as necessary. Large scale details of stormwater restrictor structures and water main interconnects are encouraged and may be required.
All structures shall be numbered or lettered using the same system as the approved engineering plans for the subdivision. Rim and invert (or top of water main) elevations shall be shown at all structures and for all pipes entering and leaving each structure. Size, material, lengths and slopes (except slopes of water main or sanitary force main) of all pipelines shall be shown on the plan or in a table thereon. Sewer and water service stub locations shall be shown, including the b-box. All b-boxes shall be visible, accessible and be keyed in the presence of the Director of Public Works, or their representative, prior to acceptance. All valve boxes shall be similarly visible, accessible and keyed.
Topographic surveys of all stormwater management facilities shall be shown certifying all critical elevations, volumes and restrictor sizes. Elevations and cross sections of critical stormwater overflow routes may also be required as deemed appropriate by the Village Engineer.
All roadways shall be cross sectioned (top of curb, centerline and top of curb) with elevations provided at minimum one hundred foot (100') intervals and at all crests and low points.
Record drawing intersection grades shall be provided such that the design engineer confirms compliance with accessibility standards.
Street lights and all underground wiring shall be shown.
Following the completion of, but prior to the Letter of Credit (or other guaranty) reduction with regard to the sanitary sewer and water main service stubs, an interim record drawing shall be submitted in an electronic format showing the actual constructed locations of sewer stubs and b-boxes.
The condition of the bench marks shown on the approved engineering plans shall be verified and noted on the construction record drawings. Elevations of the top of all fire hydrants in the subdivision shall be shown for use as bench marks for all future construction within the subdivision. All elevations shall be referenced to National Geodetic Vertical Datum of 1988 (NGVD 1988).
The final construction record drawing shall have the following statement affixed and signed:
