§ 851. Development inspections.

Inspections are required for each of the following phases, as applicable to the actual work to be performed under the development permit:

(a)

Erosion and sedimentation control. Required erosion and sedimentation control measures must be installed in accordance with the approved soil erosion and sedimentation control plan prior to any development activity and as development progresses. Prior to clearing or clearing and grubbing of the property or any portion included under the development permit, inspection of erosion and sedimentation control measures and protective devices for undisturbed areas shall be required. Inspection of erosion and sedimentation control measures will be conducted on a continuing basis.

(b)

Stormwater facilities. Construction of the stormwater system shall be initiated as part of the grading of the site. Storm water detention facilities shall be constructed prior to the installation of any other site improvements, and may be utilized under proper design as sedimentation basins during development. Installation of all other storm drainage pipes, culverts, headwalls, and ditches, shall be coordinated with the construction of streets and other site improvements, as appropriate. Upon installation of storm drainage pipe, detention, or other storm water facilities, inspection and approval shall be required prior to continuation with subgrade preparation.

(c)

Grading. Upon completion of street grading, if applicable, inspection and approval shall be required prior to trenching or continuation with subgrade preparation.

(d)

Street curbing and gutter (if provided). After grading is completed and approved, the curb lines shall be staked by the developer's registered land surveyor. Inspection shall be requested after the subgrade is compacted and forms or string line have been set. Street width and vertical and horizontal alignment may be spot checked.

(e)

Sub-grade of streets. After the earth work has been completed, all storm drainage and other underground utilities have been installed under the roadbed, and the backfill in all such ditches thoroughly compacted, the subgrade shall be brought to the lines, grades and cross section shown on the plans. If any sections of the subgrade are composed of unsuitable or unstable material, such material shall be removed to the depth directed by the inspector and replaced with suitable, thoroughly compacted material. Prior to placement of the street base, the subgrade shall be compacted to 95 percent density. Testing for sub-grade compaction will be required, including two tests at each sanitary sewer manhole.

(f)

Utilities. Before any street base is applied, all of the underground utilities—water mains, sewer mains, gas mains, or any other underground utilities, and all service connections related thereto, that will be located under the street base shall be installed completely and provided throughout the length of the street and across the flat section. If a public water system is to be installed, the improvements are to be reviewed, approved and inspected by the water provider.

(g)

Street base. The base shall be string-lined for depth and crown. The street base shall be roll-tested with an 18-ton tandem dump truck and shall pass to the satisfaction of the inspector. When testing is required by the inspector, it is the responsibility of the developer to ensure that all required tests are made and reported to the inspector. The cost of all testing and quality control shall be performed at the expense of the developer by qualified testing laboratories. If deemed necessary by the inspector, additional tests will be required.

(h)

Paving. The Inspector shall be on site during the paving process to check consistency, depth, and workmanship, as applicable. For asphalt paving, the temperature of the material will be monitored and the street will be cored after completion to check thickness and density. Satisfactory test results of the cores shall be delivered to the public development department and the Jackson County Water and Sewerage Authority (where utilities are involved) prior to approval of a final subdivision plat or certificate of completion.

(i)

Tree protection and landscaping. Inspections for tree protection measures and the installation of landscaping shall be as specified in article 12 of this UDC.

(j)

Final. A final inspection of the development, once complete, shall be required.
