The following requirements shall be incorporated into the design of all streets.
(A) Vertical alignment; grades. The maximum grade on a major or minor arterial shall be 5%. The maximum grade on all other streets shall be 8%. The minimum grade on all streets shall be 0.40%. All street grades shall be subject to the approval of the village’s consulting engineer.
(B) Horizontal alignment.
(1) Horizontal curves. When a centerline deflection angle is greater than one degree, the following curves shall be required in the street: major and minor arterials and collector streets shall have a minimum centerline radius of 300 feet and a minimum length of curve of 100 feet; arterials and collectors having a design speed and/or expected posted speed greater than 30 mph shall be consistent with the latest revision of the horizontal curvature requirements of ASSHTO, A Policy on Geometric Design of Highways and Streets for the appropriate roadway classification; all other types of streets shall have a minimum centerline radius of 100 feet. The pavement in all cases shall be wide enough to allow the movement of a WB-50 Design vehicle, as described in the Illinois Department of Transportation Design Manual.
(2) Intersections. Intersections of major and minor arterials and collectors with roadways of the same classes shall not be closer than one quarter of a mile from any other such functionally classed roadways’ intersections. These intersections shall be located at the quarter mile grid points.
(3) Street offsets. Street centerline offsets shall not be less than 125 feet, unless otherwise warranted to the satisfaction of the village’s consulting engineer.
(4) Curb corners. All curb corners shall have a minimum radius of 25 feet.
(C) Pavement. All local and collector streets shall be installed in accordance with the following pavement standards.
(1) Subgrade. At the option of the subdivider, 12 inches lime stabilized soil per latest IDOT Standard shall be employed within the street area (omit curb area).
(2) Asphalt; pavement alternate.
(a) Alternates.
1. Alternate A. If the subgrade is treated as in above, the pavement design will consist of four inches of bituminous concrete binder course, Class I (A Binder) and one and one-half inches of bituminous concrete surface course, Class I (gradation of coarse aggregate to be CA 16).
2. Alternate B. If the subgrade is not lime treated, the pavement shall consist five inches bituminous concrete binder course, Class I (A Binder) and two inches of bituminous concrete surface course Class I (gradation of coarse aggregate to be CA 16).
(b) Subgrades. All subgrades shall be inspected by the village’s consulting engineer and, if he or she deems necessary, proof rolled prior to paving.
(c) Increases. If the street is a minor arterial, the above binder and surface shall be increased to six inches and two inches for the lime treated and eight inches and two inches respectively for the non-lime-treated subgrades.
(3) Concrete; pavement alternate.
(a) Regardless if the subgrade is treated, a minimum of six inches unreinforced portland cement concrete pavement according to § 408 of IDOT specs shall be employed. All transverse contraction joints shall be 15 feet and sealed per ASTM D3405.
(b) If the street is a minor arterial, the pavement shall be increased to eight inches. All transverse contraction joints shall be 20 feet and sealed per ASTM D3405.
(4) Pavement design.
(a) All major arterial pavements shall be designed in accordance with the requirements contained in the latest, revised edition of the IDOT Design Manual and shall be designed for a 20-year period. The minimum requirements listed in the tables of the Design Manual shall govern at all times.
(b) A state bearing ratio of 3.0 (IBR = 3.0) shall be used in pavement design unless the subdivider’s engineer submits soil tests justifying a different IBR.
(c) Vehicular traffic volumes and vehicle classification percentages used in the design shall be approved by the village’s consulting engineer.
(d) In all cases, the minimum street will govern if the above major arterial design is less.
(D) Pavement width.
(1) All streets shall be improved with pavements to an overall width in accordance with the following general guidelines, which are subject in every case to the discretion of the village.
Type of Street | Pavement Width (Edge of Pavement to Edge of Pavement) |
Collector street | 27 feet minimum |
Local street | 27 feet minimum |
Major arterial | 40 feet minimum and as required by IDOT |
Minor arterial | 32 feet minimum |
(2) The minimum pavement width shall be 27 feet from the edge of pavement to edge of pavement, not including the curb and gutter. Different widths may be used depending on the anticipated traffic volumes and parking demand. These widths of pavement shall be determined by the Planning Commission and the village’s consulting engineer in consultation with the engineer for the subdivider. If a pavement width narrower than the above stated minimum results from this consultation, the subdivider shall install “No Parking” signs at his or her expense.
(E) Curb and gutter.
(1) The standard curb and gutter required adjacent to flexible pavement shall be a mountable type constructed portland cement concrete with the following dimensions: 24 inches wide, eight inches thick on the front face (pavement side), ten inches thick on the back face, seven inches thick at centerline (flow line), and a ten-inch radius in the flow line. The curb and gutter adjacent to concrete pavement, if poured monolithically, may be limited to the thickness of the pavement.
(2) In subdivisions proposed to have streets with an anticipated daily traffic volume of 2,500 or more, a barrier type curb and gutter similar to Type B6.18, as described in the Illinois Department of Transportation Highway Standards, shall be used. Other locations where a barrier type curb and gutter are required shall be determined by the engineer for the subdivision and the village’s consulting engineer.
(F) Pavement crown. The minimum crown used on all pavements shall be one-quarter inch per foot measured from the edge of the pavement to the centerline of the street.
(G) Cul-de-sac streets. Local streets that are also cul-de-sac streets shall be no more than 600 feet long unless necessitated by topography in which case they shall be no longer than 1,000 feet unless provision is made for an interim turnaround with a radius sufficient to accommodate emergency vehicles and/or a median entrance. (See division (I) below.) A turnaround shall be provided at the enclosed end having an outside roadway diameter of at least 86 feet edge-to-edge of pavement and a street right-of-way diameter of 110 feet. No obstructions shall be permitted in the cul-de-sac turnaround.
(H) Stub streets. Access shall be provided to adjoining property not yet subdivided. Proposed streets shall be extended by dedication to the boundary of such unsubdivided property. At the end of all temporary stub streets, a barricade meeting the provisions of the Illinois Manual on Uniform Traffic-Control Devices shall be installed by the subdivider. Stub streets in excess of 250 feet shall be provided with a temporary cul-de-sac with an outside roadway diameter of at least 90 feet. The type of construction shall be determined by the village’s consulting engineer. The subdivider shall dedicate a temporary easement to the appropriate street authority in the amount needed in excess of the normally required right-of-way for the temporary turnaround. When the street is extended in the future, the extra turnaround pavement shall be removed and curb and gutters and sidewalks constructed by the subdivider developing the adjacent property.
(I) Multiple access. Any area of development containing 70 or more single-family lots (or equivalent population) shall be served by two functioning points of access. Where higher densities of development are proposed, a divided type entrance roadway may suffice with a median of adequate width to ensure continued emergency access lanes on one side. Depending on location and height of nearby poles or trees, the required median width shall range between 12 and 30 feet. This type of roadway construction is intended to accommodate higher density developments and not to lengthen the overall length of a cul-de-sac.
(J) Restriction of access. When a subdivision or a portion of it adjoins a major or minor arterial, no lot shall have direct access to the arterial. The lot shall have adequate depth for screen planting on the portion of the lot contiguous to the major or minor arterial.
(K) Street names and street signs.
(1) A proposed street that is in alignment with and/or joins an existing named street shall bear the name of the existing street. In no case shall the proposed name of a street duplicate the name of an existing street within the plat jurisdiction of this chapter. The use of the suffix “street”, “avenue”, “boulevard”, “driveway”, “place”, “court” or similar description shall not be a distinction sufficient to constitute compliance with this requirement.
(2) Street names signs shall be erected at all intersections within the village’s jurisdiction at the expense of the subdivider and shall be subject to the specifications of the Illinois Manual on Uniform Traffic-Control Devices.
(L) Private streets. There shall be no private streets platted in any subdivision. Every subdivision lot shall be served from a publicly dedicated street.
(M) Alleys. Alleys are not recommended in residential subdivisions unless deemed necessary by the Planning Commission.
(N) Ramps. Where sidewalks cross a barrier type curb and gutter as described in division (E) above, ramps shall be constructed to accommodate the disabled. These ramps shall be constructed to IDOT standards. Inlets for storm drainage shall not be located so that a pedestrian way will be interrupted by the inlet grates. Other locations where these ramps are required shall be determined by the village’s consulting engineer.
(O) Typical street section.
(P) Medians and islands.
(1) Where medians or islands are proposed they shall be constructed with barrier curbing. All medians and islands shall be the responsibility of the subdivider and/or a subdivision association to maintain. No sign may be installed in the median which blocks the sight distance at the intersection. If such a sign is to be installed, detailed plans for the sign shall be submitted with the construction plans for approval. In no case shall an island or median contain any other sign or structure, except as may be placed for traffic control under the direction of the village’s consulting engineer.
(2) The subdivider or subdivision association may landscape medians or islands. Ground cover may not exceed a maximum height of 12 inches. Any additional living plant material must be maintained to allow visibility across, over or through medians and islands at a height of three to ten feet above the adjacent roadway pavements.
(Prior Code, § 150.041) (Ord. 96-006, passed 2-5-1996)
(A) Size of lots. Minimum lot sizes shall be the minimum for the applicable zoning district of Riverton, except when a private sewage disposal system is necessary. When a private sewage disposal system will be used for any length of time, lots shall be a minimum of 20,000 square feet.
(B) Lot arrangement.
(1) Side lot lines shall be at right angles to straight street lines or substantially radial to curved street lines. However, for purposes of solar orientation, side lot lines need not be at right angles to straight street lines or radial to curved street lines; provided that, side lot lines run within 20 degrees east or west from due north to due south. If side lot lines are being varied for solar orientation, layout and building setbacks shall also be oriented with their long axis running from east to west, with a possible variation of 20 degrees to the southwest or 20 degrees to the southeast.
(2) Each lot shall front upon a public street.
(3) Flag lots shall be permitted only if the Planning Commission determines that no public health and safety problems or additional costs or difficulties providing municipal services will result.
(4) Through lots shall be permitted only when access is prohibited to one street as described in § 155.117(J) of this chapter.
(5) All lots must contain sufficient buildable area.
(C) Sizes of blocks. Blocks shall not be less than 400 feet, nor more than 1,200 feet, in length measured along the greatest dimension of the enclosed block area. In blocks over 800 feet in length, the Planning Commission may require one or more public crosswalks with a right-of-way of not less than ten feet in width to extend entirely across the block at locations deemed necessary at intervals not closer than 400 feet.
(D) Survey monuments. All survey monuments shall be located and be made of the appropriate material as required by state law.
(E) Lot grading.
(1) Trees that cannot be saved, stumps, boulders and similar items shall be removed.
(2) All grading in the subdivision shall be related to the topography of the surrounding area. All street embankments shall be raised at least one and one-half feet above the high water elevation.
(3) All building lots shall be graded or have natural slopes that will properly allow surface drainage to flow away from the principal structures to be located on the lot.
(4) Grading in the subdivision shall provide alternate drainage ways for the purpose of carrying water away from homes and preventing damage during periods of heavy rainfall.
(Prior Code, §150.042) (Ord. 96-006, passed 2-5-1996; Am. Ord. 17-002, passed 2-6-17)
(A) During construction of public improvements, measures shall be taken to control erosion and sedimentation to ensure that sediment will not be transported from the site by a storm event of two-year frequency or less. The erosion and sediment control plan shall include measures to stabilize and protect disturbed areas, keep runoff velocities low, retain sediment on site and protect disturbed areas from runoff. The location, type and configuration of controls such as swales, berms, dams, sediment basins and release mechanisms shall be included with the construction plans.
(B) Temporary or permanent soil stabilization measures, whichever is applicable, shall be applied within 15 days after final grading to all areas where the soil has been disturbed or the vegetative cover removed. Seeding mixtures and rates, types of sod, method of seed bed preparation, expected seeding dates, type and rate of lime and fertilizer application and kind and quantity of mulch for temporary or permanent vegetative control measures shall be included with the construction plans.
(C) An IEPA storm water permit shall be obtained by the subdivider as required by law.
(Prior Code, § 150.043) (Ord. 96-006, passed 2-5-1996)
(A) Utility easements.
(1) Utility easements shall be provided along front, rear or side lot lines for the purpose of erecting and maintaining one or more of the following facilities: storm sewers, sanitary sewers, surface drainage, gas mains, underground electric lines, telephone lines, cable TV and such other utilities reasonably required for an urban structure.
(2) Easements shall be a minimum of 15 feet in width. A utility may be located in the street right-of-way if the respective company so desires and appropriate permits have been obtained.
(3) Alternate locations for various utilities shall be decided upon by the appropriate utility companies, subject to the approval of the village’s consulting engineer. In no case shall streets, permanent buildings or other human-made improvements that obstruct surface drainage be placed on rear or side lot easements.
(4) It is the responsibility of the subdivider to notify all utility companies in writing when the land to be developed has been graded in accordance with the construction plans and is ready for installation of a given utility.
(B) Location of utilities.
(1) Utilities (sewers, electric, water and gas), whenever possible, shall be located in the public right-of-way or front lot easement in the following manner: water and electric lines shall be located on the south and east sides; sanitary sewer and gas lines shall be located on the north and west sides. In some cases, however, electric lines may also be located on the north and west sides.
(2) The placement of storm sewers or electric lines in the rear of a lot is not acceptable unless circumstances determined by the village’s consulting engineer require their placement in the rear, in which case the following easement diagrams indicate placement:
(a) Ten-foot easements. When an easement will not include sanitary sewer or surface drainage systems, a ten-foot easement width shall be sufficient and the utilities shall be located as follows:
(b) Fifteen-foot easements. When an easement will include either a sanitary sewer system or a surface drainage system, but not both systems, a 15-foot easement shall be required and the utilities shall be located as follows:
(c) Twenty-foot easements. When a utility easement will include both a sanitary sewer system and a surface drainage system, a 20-foot easement shall be required and the utilities shall be located as follows:
[Image follows on next page]
(d) Side yard easements. When sanitary or storm sewers are located in the rear of a lot, a ten-foot easement in the side yard shall be required from the street right-of-way to each manhole or inlet.
(Prior Code, § 150.044) (Ord. 96-006, passed 2-5-1996)
(A) All subdivisions shall be developed with adequate surface drainage. Surface water drainage improvements shall consist of storm sewers and/or open channels, inlets, catch basins and manholes designed and constructed to conform with standards established by the village’s consulting engineer and shall adequately drain the area being developed, including drainage from other areas which naturally drain through the areas being developed. Inlets and/or catch basins shall be spaced so that water will not flow overland more than 500 feet and shall be located so that, in no case, will water be required to flow across a street. Water shall not be retained outside the center ten feet of drainage utility easement. Inlets covered by a metal grate shall have a grate of a type that will not be hazardous to a bicyclist.
(B) If, as the result of subdivision development, surface water is deposited in existing roadside ditches in quantities exceeding their capacity, the developer shall improve the ditches and replace culverts as needed to handle the flow.
(C) Unless engineering evidence is presented to the village’s consulting engineer warranting exceptions, storm sewers which will drain 20 acres or less for residential development shall be designed and constructed to meet the following criteria:
(1) Major and minor arterials: ten-year storm frequency; and
(2) All other areas: five-year storm frequency.
(D) (1) It shall be the responsibility of the subdivider to provide grade control for rear lot drainage to each lot owner. Swales are not public works which shall be dedicated to and accepted by the village; nevertheless, no construction surety shall be fully released until the village’s consulting engineer has approved the swales in the subdivision. The village’s consulting engineer will not approve any swale until adequate turf and/or grass has been established at the elevations set forth in the construction plans. Upon approval by the village’s consulting engineer, it shall be the lot owner’s responsibility to maintain the drainage course and to keep it free from features that restrict natural drainage. All swales less than 1% in grade shall have either of the following:
(a) An eight-inch minimum underdrain pipe that allows water seepage as indicated on the drawing entitled “Detail of Yard Underdrain” set out at Appendix A at the end of this chapter; or
(b) A portland cement concrete swale, five inches thick, as indicated on the drawing entitled “Paved Ditch Detail” set out at Appendix B at the end of this chapter.
(2) End sections shall employ a grated cover to keep animals or children from trying to enter the system.
(E) The controlled release and storage of excess storm water runoff shall be required in combination for all of the areas indicated on the preliminary plan.
(1) The controlled release of storm water runoff shall not exceed the release or discharge rate which existed at the site prior to development. This rate shall be known as the predeveloped discharge rate. In the case of multiple discharge locations, no location shall discharge at a rate higher than the predeveloped discharge rate for that location under any set of conditions. The controlled release rate in any case shall not exceed the rated capacity of the existing natural downstream outlet channel or storm sewer system as determined by the village’s consulting engineer. The rate at which storm water runoff is transported into a designated storage area may be as determined by the design engineer and is unrestricted.
(2) A natural or surface channel system shall be designed with adequate capacity to convey the storm water runoff from all tributary upstream areas through the development. This bypass channel shall be designed to carry the peak rate of runoff from a 50-year storm assuming all storm sewers are blocked and that the upstream areas are fully developed and have been saturated with antecedent rainfall. No habitable structures shall be constructed within this channel, however, streets and parking or playground areas and utility easements shall be considered compatible primary uses.
(3) (a) Storm water runoff capacity of detention facilities and discharge rates from such facilities shall be calculated by analyzing volume and rate of runoff during pre- and post-development conditions for the ten-year and the 100-year recurrence intervals.
(b) Storage capacity and discharge rates shall be based on the maximum calculated volume and peak flow of storm waters, respectively.
(c) Storage facilities shall be designed using the soil conservation service (SCS) method of calculating runoff discharge rate and total volume of storage. The rational method of calculating runoff may be used for subdivisions less than 20 acres.
(d) The storage volume shall be provided for the fully developed watershed that is tributary to the area designated for detention purposes. The control structure for discharge shall maintain the release rate at or below the rate established in division (E)(1) above for all rainfall events of 100 years or less frequency.
(4) (a) Detention reservoirs or any bottom storm water storage areas shall be designed to serve a secondary purpose for recreation, open space or other types of uses that will not be adversely affected by occasional or intermittent flooding. A method of carrying the low flow through these areas shall be provided in addition to a system of drains, and both shall be provided with a positive gravity outlet to a natural channel or other storm sewer facility with adequate capacity. The combination of storage of the water from a 100-year storm and the design release rate shall not result in a storage duration in excess of 72 hours. Maximum depths of planned storm water storage shall not exceed four feet unless the existing natural ground contours and other conditions lend themselves to greater storage depth, which shall be approved by the village’s consulting engineer. Minimum grades for turf areas shall be 0.6% and maximum slopes shall be 10%. Storage area side slopes shall be kept as close to the natural land contours as practical and a 10% slope or less shall be used whenever possible. If slopes greater than 10% are necessary to meet storage requirements or area restrictions, approval shall be obtained from the village’s consulting engineer, and suitable erosion control shall be provided in addition to the protection required to ensure public health and safety.
(b) Outlet control structures shall be designed as simply as possible and shall require little or no maintenance and/or attention for proper operation. Each storm water storage area shall be provided with a method of emergency overflow in the event that a storm in excess of the 100-year return frequency storm occurs. The emergency overflow facility shall be designed to function without maintenance and/or attention and shall become part of the natural or surface channel system described in division (E)(2) above. Hydraulic calculations shall be submitted to substantiate all design features. Both outlet control structures and emergency overflow facilities shall be designed and constructed to fully protect the public health and safety. Storm water runoff velocities shall be kept to a minimum and turbulent conditions at an outfall control structure will not be permitted without complete protection for the public safety. The use of restrictive fences shall be kept to a minimum and shall be used only as a last resort when no other method is feasible.
(5) Retention reservoir or wet bottom storm water storage areas shall be designed with all of the items required for detention reservoir storage areas; except that, a low flow conduit and a system of drains with a positive gravity outlet shall not be required. However, the following additional conditions shall be complied with.
(a) Water surface area shall not exceed one-tenth of the tributary drainage area.
(b) Shoreline protection shall be provided to prevent erosion from wave action.
(c) Minimum normal water depth shall be four feet. If fish are to be used to keep the pond clean, a minimum of one-fourth of the pond area shall be a minimum of ten feet deep.
(d) Facilities shall be available, if possible, to allow the pond level to be lowered by gravity flow for cleaning purposes and shoreline maintenance.
(e) Control structures for storm water release shall be designed to operate at full capacity with only a minor increase in the water surface water level. Hydraulic calculations shall be submitted to substantiate all design features.
(f) Aeration facilities to prevent pond stagnation shall be provided, if necessary. Design calculations to substantiate the effectiveness of these aeration facilities shall be submitted with construction plans. Agreement for the perpetual operation and maintenance of aeration facilities shall be prepared to the satisfaction of the village’s consulting engineer and Planning Commission.
(6) Where developments form only a portion of the watershed or contain portions of several watersheds, the requirements for providing storage shall be based upon that proportion of the area being developed as compared to the total watershed tributary to the storage area. Compensating storage will be acceptable whenever it is justified and feasible. As a watershed is developed with a series of storm water storage facilities, due consideration will be given for calculations of the allowable release rate and capacity of the natural or surface channel system as described in division (E)(2) above.
(7) Where development of a property presents the threat of flooding or damage by flash flood runoff to downstream residents, the facilities for storm water runoff control shall be constructed prior to any earthmoving or drainage construction on the project site.
(8) The construction of the storm water control systems shall be accomplished as part of the cost of land development. If the amount of storage capacity can be increased to provide certain benefits to the surrounding properties, negotiations for public participation in the cost of such development may be feasible.
(9) The ability to retain and maximize the ground water recharge capacity of the area being developed is encouraged. Design of the storm water runoff control system as provided in division (E)(4) above shall give due consideration to providing ground water recharge to compensate for the reduction in the percolation that occurs when the ground surface is paved and/or roofed over. The use of natural gravel deposits for the lower portions of storm runoff storage areas, the flattening of drainage slopes and the retention of existing topography are samples of possible recharge methods.
(10) During the construction phase of land development, facilities shall be provided by appropriate stockpile design, to prevent the erosion and washing away of the earth. Silting of downstream areas shall be prevented through the strategic use of silting basins, sodding of runoff channels and by limiting the period of time during which the earth is stripped of vegetation.
(11) Final engineering plans shall show complete details for all items covered in this section. Plans, specifications and all calculations for storm water runoff control and storm sewers shall be submitted for review and approval as part of the construction plan submittal or as part of the site plan submittal for large scale developments.
(Prior Code, § 150.045) (Ord. 96-006, passed 2-5-1996)
(A) Where an underground utility is to be placed in an area which has a permanent type street or sidewalk surface, or upon which such a surface is to be constructed within a period of one year, the backfill above the utility or in case of sewers, above the top of the granular cradle, to the level of the bottom of the permanent type pavement shall be made. This material will be in all areas where utility trenches cross the pavement subgrade, except in areas which will be lime treated or areas where rock will be used to stabilize the subgrade. The backfill shall be IDOT CA-6 or CA-7 crushed stone. Boiler slag will not be permitted.
(B) As an alternate, the use of “flowable fill” will be permitted. This mix shall consist of a lean concrete mix with no less than 50 pounds of cement per cubic yard, 200 to 600 pounds of fly ash, 2,000 to 3,000 pounds of fine aggregate and 35 to 65 gallons of water. Minimum 28-day compressive strength shall not be less than 150 psi.
(C) In areas not now subject to vehicular traffic, nor in the opinion of the village’s consulting engineer likely to be within a period of one year, backfill may be made with selected excavation material which is free from clods and stones; provided, such trench backfill is adequately jetted from the bottom up completely filling the trench immediately after backfilling.
(Prior Code, § 150.046) (Ord. 96-006, passed 2-5-1996)
Concrete sidewalks at least four feet wide and four inches thick shall be constructed on both sides of each street at least four and one-half feet from and at least four inches above the backs of the curbs. Sidewalks shall be located one foot inside the street right-of-way. Sidewalks shall be constructed along all streets bordering the subdivision. All sidewalks along arterials and minor arterials shall be five feet wide. All walks at corner lots shall be extended out to gutter(s) either by a common extension at the center or continue at right angles to the gutter.
(Prior Code, § 150.047) (Ord. 96-006, passed 2-5-1996)
(A) Sanitary sewers.
(1) When a subdivision is located within the service area of a public sanitary sewerage system, sanitary sewers shall be constructed throughout the entire subdivision in such a manner as to serve adequately each building lot.
(a) Public sanitary sewers shall be located in the north or west boulevard (between curb and sidewalk) within the street right-of-way or in a 15-foot easement behind the sidewalk within the house setback area. Parallel sewer lines along the street may be used. Sanitary sewers shall not be located in the rear yard.
(b) Under no circumstance shall the entrance of storm water or ground water to the sanitary sewers be permitted.
(c) All sanitary sewer collections and disposal systems shall comply with the ordinances of the village and the requirements of the Illinois Environmental Protection Agency.
(2) Acceptable sanitary pipe materials shall be acceptable to the village consulting engineer and shall consist of:
(a) PVC composite sewer pipe conforming to ASTM D 2680 with solvent weld or gasketed joints;
(b) Polyvinyl chloride (PVC) sewer pipe conforming to ASTM D 3034, type PSM for sizes four inches to 15 inches and ASTM F-679 for sizes 18 inches to 27 inches. Minimum acceptable SDR shall be 35; or
(c) PVC corrugated sewer pipe with a smooth interior. This pipe shall conform to the requirements of ASTM Standard F-794 and Uni-bell Uni-P-9. Pipe shall be made of PVC material having a cell classification of 124-54-B as defined in ASTM D 1784. Pipe stiffness at 5% deflection shall be 46 psi for all sizes (eight inches to 30 inches) when tested in accordance with ASTM 2412. PVC pipe meeting ASTM F-942 is not acceptable.
(3) All sanitary laterals will be marked by using a two-inch by four-inch (painted orange) board four feet above the ground to denote location of service lines.
(B) Private sewage disposal systems. Where no public sanitary sewerage system is available (see § 155.027(A)(1) of this chapter), individual sanitary disposal systems shall be installed to service individual dwelling units according to conditions set forth in § 155.027 of this chapter. These sanitary disposal systems shall be installed in accordance with the latest revised edition of the State Private Sewage Disposal Licensing Act and private sewage disposal code promulgated by the State Department of Public Health and the applicable ordinance of the village. Sufficient area shall be provided to accommodate two seepage fields.
