An observation pit shall be used in gravelly materials.

For permit applications associated with the construction of a new home or reconstruction of a home on an existing lot, additional soil testing will be required if the procedure described above results in a determination that an at grade system or mound system would be required. Soil borings will be required for all areas of the lot within three hundred feet (300') of the residence to determine if any area of the property is suitable for a soil treatment trench system. If no such area is found on the property, an at grade system or mound system meeting the design requirements of subsection (H)4 or (H)5 of this section will be permitted.

(3) Observation and determination of soil characteristics may also be determined from a pit dug by a backhoe or other excavating equipment. The village may require soil pits (backhoe excavation) in cases where the ground is frozen, where the soil materials are considerably varied in texture, where there has been previous or current fill material or cutting of soils, or where gravelly soils are encountered. Soil pits shall be prepared at the perimeter of the expected soil absorption area to minimize damage to natural soil structure. Soil pits shall extend a minimum of sixty inches (60") below the natural ground surface.

(4) Site characteristics to be described include zones of seasonal and permanent water saturation, United States department of agriculture (USDA) soil textural changes, USDA soil structural features for each horizon, slope, compaction and depth; soil coloration; consistence; coatings; depth of limiting layer; depth of soil mottling; internal drainage classification; permeability range; and other limiting soil characteristics that may reduce permeability.

Notes:
1. These distances have been determined for use in clay, silt, and loam soils only. The minimum distances required for the use of a private sewage disposal in sand or other types of soil shall be determined and approved by the village when the soil in question can provide equal or greater treatment of the sewage. See subsection 4-2-7(D) of this chapter for additional requirements.
2. The building sewer may be located to within 10 feet of a well or suction line from the pump to the well when cast iron pipe with mechanical joints or schedule 40 PVC pipe with watertight joints is used for the building sewer.
3. See subsection 4-2-7(D)4 of this chapter for details on the separation of sewer and water lines.
4. The minimum distance allowable from an inground swimming pool is 25 feet. See subsection 4-2-7(L) of this chapter for additional requirements.
5. Whichever line is most restrictive.
6. Class V injection wells are defined in Illinois pollution control board rules. They are typically a shallow well used to place fluids directly below the land surface. See e.g., 35 Illinois administrative code 704.105, 704.106, and 704.280.
7. A lesser separation distance may be obtained with approval or a waiver from the IEPA.

Septic Field Inspection: When tanks and field tile are complete, before backfill.

Final Inspection: When building is completely finished and rough grading done. For houses, a water sample and spotted survey are required. For all permits a spotted survey is required. Note: Pole buildings require final inspection.

Inspection for Certificate of Occupancy: Issued when all final corrections made. Penalties shall be incurred for occupancy without certificate.
(Ord. 76-6, 5-24-1976)

Swimming Pool Inspection, in order of occurrence:

1. When bottom is ready to be poured and all grounding in place.

2. When deck is ready to be poured and all grounding in place.

3. When all work described in the building permit application is completed.

Satellite Antenna Inspection: When antenna is anchored to the concrete platform and effectively grounded and screening is in place as described in the building permit application.

Final Inspection: When the building, including pole buildings, is completely finished with those items required by the provisions of this Chapter and rough grading done.
(Ord. 89-13, 10-23-1989)

Inspection for Certificate of Occupancy or Completion: A certificate of occupancy or completion shall be issued when all final corrections are made and a spotted survey is received. In addition, for a residence, there is required prior to the issuance of a certificate of occupancy (i) an as-built drawing of the septic system, (ii) a water sample and (iii) a successful test of the Emergency Number Telephone System. Occupancy of any building, including, but not limited to, storage of furniture, equipment or other personal property, or the use of such building, prior to the issuance of a certificate of occupancy or completion, shall be subject to the fines and penalties of Section 4-1-9 of this Title.
(Ord. 03-17, 8-25-2003)

Other Inspections: In addition to the called inspections above, the Building Officer may make or require any other inspections to ascertain compliance with this Code and any other laws enforced by the Building Officer. Work shall not be done on any part of the building or structure beyond the point indicated in each successive inspection without first obtaining the written approval of the Building Officer. Such written approval shall be given only after an inspection has been made at each successive step in the construction as indicated by each of the inspections required above.

3. In addition to Section R-112: A building plan for each model must be filed with the Building Officer incorporating all off-site constructed aspects of the structure as well as its final site assembly down to the foundation. These plans must bear the seal and signature of a registered architect or professional engineer licensed to practice in the State of Illinois.

4. Values for Table No. 2-A shall be as follows: Roof live load = 25 PSF; Roof snow load = 30 PSF; Wind velocity at 30 feet above ground = 30 PSF; Seismic Condition = Zone 1; Subject to damage from weathering - yes, 6" above grade; Subject to damage from frost line depth - yes, 3'6" below grade; Subject to damage from termites - yes, moderate; Subject to damage from decay - yes, moderate.
