Drainage pipe installed with other drainage structures and fire protection improvements before backfilling.
(b) 
Fine grade of road subbase (prior to paving).
(c) 
Base course installation.
(d) 
Pavement wearing course installation.
(e) 
Landscaping.
(f)

B. 
Notification.
(1) 
The developer shall notify the Planning Board in writing five days prior to the completion of each construction phase listed above.
C. 
Testing.
(1) 
The following tests shall be approved by the Town Engineer at the applicant's expense:
(a) 
Subbase. One sample per 1,000 feet with a minimum of two samples per road. This minimum will be supplemented by additional sampling if variations in the types of soil are detected by the technicians. These samples will be tested in the laboratory in accordance with § 220-3.23.
(b) 
Stabilized base. Generally one design per subdivision will be made unless the soil varies so much that one design is not practical or that one of the materials used as a stabilizer is changed. This design shall be submitted for approval prior to construction of the base. (See § 220-3.23C.)
(c) 
Asphaltic concrete paving. One core from the finished pavement will be taken for each 1,000 feet of road or if the road is less than 1,000 feet, one core per road. There shall be a minimum of two cores per project, with the project area submitted to the Town Engineer for acceptance. The cores will be returned to the laboratory and tested for the following:
[1] 
Depth of asphaltic concrete.
[2] 
Depth of stabilized base.
[3] 
Extraction and gradation of the asphaltic concrete.
[4] 
Asphalt content of the stabilized base.
[5] 
Visual description of quality of stabilized base.[1]

A. 
Upon completion of the required work and prior to the termination of bond period, the developer's engineer shall make an as-built survey of the required subdivision improvements. The information shall be incorporated on the final road and drainage plans to ensure that the required improvements have been constructed in accordance with the plans as previously approved. The information shall include, but not be limited to, road profiles, drainage inverts, catch basin grade elevations and leaching basin cover elevations, fire protection and trail improvements. The following certification shall be placed on the plans and signed by the developer's engineer:
I hereby certify that this plan shows locations, profiles and elevations of roads, curbs, drainage and other structure as actually constructed and that the information as shown hereon is obtained from an actual field survey.
Date:
Signature
License number
B. 
Three paper prints and one reproducible set of the as-built plan shall be submitted to the Planning Board and approved by the Town Engineer before the performance bond will be released.
After the completion of all work and the submission of the as-built plans and pavement core test results (see § 220-3.18), the Superintendent of Highways and the Town Engineer will make a final inspection to determine whether the completed improvements are in accordance with the approved drawings and specifications. Upon a satisfactory final inspection report, action will be taken to release the developer's performance bond. The applicants attention is directed to §§ 220-3.07 and 220-3.08 regarding additional bonds that are required prior to release of this performance bond.
