(A) 
Upon approval of the preliminary plan and the engineer's plans and specifications, the subdivider shall construct and install the required subdivision improvements prior to filing with the Plat Officer the final plat for final approval.
(B) 
All subdivision improvements within the plat jurisdiction of the Village of Harristown shall be designed, furnished and installed by the subdivider at his own expense in accordance with the provision of this article and other applicable Village, county, and state regulations. All improvements shall be subject to inspection and approval of the Village Building Inspector or a qualified engineer appointed by the Village.
(C) 
In lieu of construction, the subdivider may post with the Village a cashier's check, negotiable securities, or a surety bond payable to the Village of Harristown sufficient to cover the full cost of the said improvements as estimated by a registered professional engineer and approved by the Plat Officer, to assure the satisfactory installation of said improvements as outlined in Article VIII.
(D) 
The developer is responsible for all required improvements until released by inspection and approval one year after completion and construction. A construction guarantee of 10% of the cost of the improvements shall be retained by the Plat Officer during this time.
(E) 
All construction must be completed within two years. Construction of all improvements required by this Code must be completed within two years from the date of the approval of the preliminary plan by the Village Board unless good cause can be shown for granting an extension of time.
(F) 
Inspection at subdivider's expense.
(1) 
All public improvements proposed to be made under the provisions of this Code shall be inspected during the course of construction by the Village Engineer or a duly designated deputy.
(2) 
During the course of construction of the improvements, the subdivider shall be required to notify the Village Engineer 48 hours before each of the following operations in order that the Engineer or a duly designated deputy may make required inspections:
(a) 
Before base material is deposited in place for inspection of all street subgrades; monumentation and grading.
(b) 
Before paving is placed on the base material, for inspection of the base construction.
(c) 
Before any backfilling operations whatsoever following the installation of water, sanitary or storm sewers or any other underground public improvements.
(G) 
All dedications must be accepted by the Village. Final acceptance of the dedication of streets, utilities, open space or other public area shall be the responsibility of the Village Board, and shall only be done by resolution at the regular meeting of the Village Board. However, such action should only take place after receiving the report of the Village Engineer and Inspector.
(A) 
Grading — general.
(1) 
Any action causing the removal of major trees, filling of any area with more than three feet of fill material, cutting the soil or cover material from any area by more than two feet, the alteration of any natural watercourse or major drainageway, shall be considered grading and shall only be allowed when shown and approved in conformance with a preliminary grading plan.
(2) 
All grading should be kept to the minimum necessary to provide the proper relationships between lots, blocks, streets, utilities and storm drainage systems. All such grading shall be shown on the grading plan. Where it is necessary to fill to a depth of five feet or more, said fill shall be laid in layers of six inches or less, adequately watered and compacted, and then subsequent layers of six inches added in a similar manner until the desired grade is reached.
(a) 
Where areas other than roadways must be cut or filled, topsoil should either be skimmed off before grading and uniformly replaced or new topsoil of a quality acceptable to the Building Inspector must be added after the grading at average, uniform depth of not less than four inches.
(b) 
Where areas are not to be graded and are in excess of fifteen-percent slope, the Village Plan Commission may require riprapping, planting or other methods of slope stabilization. In some cases the dedication of natural easement covering such areas may be required.
(B) 
Block and lot grading.
(1) 
The finished grade of all subdivided blocks should be such that water runoff will flow freely from the block to streets, storm inlets, natural watercourses and drainage swales, and drain from the subdivision without causing erosion, flood damage, ponding or similar problems. Where the natural grade will not permit such flow additional grading must be provided.
(2) 
All individual lots should be of such elevation and grade that stormwater and sanitary waste will freely leave the site without causing erosion or flooding problems. All sites should therefore be at a reasonable level above streets, drainage and sanitary waste collection.
(C) 
Trees and grading. As many trees as can be reasonably utilized in the final development plan shall be retained and the grading adjusted where practical to the existing grades at the trees.
(D) 
Street grading. All streets shall be uniformly graded in accordance with the typical cross section shown in the engineering specifications of the preliminary plan. All trees and brush shall be removed and the roadways shall be graded to the subsoil level.
(E) 
Monumentation. Reference monuments shall be installed within all subdivisions as follows:
(1) 
The perimeter of all subdivisions shall have permanent monuments of concrete reinforced within one No. 4 vertical rod, and not less than four inches square or in diameter at the top and tapered to six inches at the bottom and 36 inches long, set flush with the adjacent ground. Each permanent monument shall have a suitable mark in the center of the top. Sufficient permanent concrete monuments shall be erected to reestablish the property lines of the subdivision.
(2) 
Monuments shall consist of five-eighths-inch iron pins not less than 24 inches in length driven into the ground.
(3) 
All lot corners shall be marked by one-half-inch iron pins not less than 24 inches in length driven into the ground similar to those monuments described in the above paragraph.
(F) 
Grading and monument inspection. No sidewalk, utility or street pavement shall be constructed within any subdivision or addition thereof until the grading and monumentation of said subdivision has been inspected.
Each street shall be graded, drained, constructed, and surfaced in conformance with the standards contained in Table VII-I of this section,[1] modification may be required however, because of soil, topographical and other natural conditions. All street improvements shall be appropriate to the type of development anticipated and durable under use and maintenance contemplated for such streets. All street bases and subbases shall be inspected before the paving surface is applied.
Portland cement concrete sidewalks shall be installed as required in Section VI and in areas around and leading to schools, parks, and shopping areas. Sidewalks shall be at least four feet wide in residential areas and five feet four inches wide in business areas. All sidewalks shall be constructed of concrete four inches thick with thickness increased to 5 1/2 inches where sidewalks are crossed by driveways and areas of unfavorable soil. A sand or gravel base at least two inches thick may be required.
(A) 
Concrete curbing or combined curb and gutter shall be constructed on each side of all street pavements except where waived by the Village Board.
(B) 
Curbing on local light traffic residential streets shall consist of Portland cement concrete and may be either plain concrete curb, eight inches in thickness and 24 inches in depth, or combination curb and gutter consisting of IDOT standard B6.12-B6.18 or B6.24.
(C) 
Curbing on business streets or major thoroughfares shall be not less than five inches in height above gutter grade and shall be of a type and section adopted as standard for the Village, or such variation thereof as may be approved by the Village Engineer.
(A) 
All parkways within the dedicated street area shall be graded and seeded in an approved manner, and care should be taken to prevent damage to water and gas shut-off valves, and the owner shall be held responsible for any damage which is incurred.
Whenever practical telephone and electric utilities shall be underground. When utility lines for telephone and electric service must be carried on overhead poles, such utilities shall be placed in rear lot line easements or designated side lot line easements. Where telephone, electric, and gas service lines are placed underground entirely throughout a subdivision area, conduits or cables shall be placed within easements or dedicated public ways in a manner which will not conflict with other underground services. Further, all transformer boxes shall be located so as not to be unsightly or hazardous to the public. All underground utility installations which traverse privately owned property shall be located in recorded easements.
The subdivider shall design and construct a storm drainage system adequate to handle maximum potential flows of water drainage from the subdivision or passing through the subdivision without causing hazard for life or property within the subdivision or surrounding land areas. All storm systems shall be designed and constructed according to the preliminary plat and shall consider the appropriate streets, storm sewers, roadway ditches, grassed swales, natural watercourses, catch basins and inlets, as may be required. All such facilities should be complimentary in design and construction. In general all areas shall be required to install storm sewers.
(A) 
Natural watercourse. Whenever practical natural open drainageways shall be utilized as part of the subdivision storm drainage system. Whenever a natural stream or other man-made important surface drainage course or agricultural drainage tiles are located within a subdivision, the subdivider shall dedicate an adequate easement along each side of the stream or tile for purposes of widening, deepening, sloping, improving, or protecting the stream or tile for drainage or floodwater retention.
The filling, alteration, widening, or any other restriction or alteration of a natural stream and flood basin shall be permitted only as shown and approved on the preliminary plat. In areas where stream slopes exceed 12%, such slopes shall either be graded, stabilized by riprapping, or some sort of planting or shall be dedicated as a natural easement.
(B) 
Drainage ditches and swales. Where roadway ditches or swales are permitted such ditches or swales shall be contained within easements at least 10 feet wide and the drainage shall be improved as follows:
(1) 
With grades to 4%, ditches may have sod bottoms and banks.
(2) 
With grades from 4% to 8%, ditches or swales must have ditch checks.
(3) 
With greater than eight-percent grades, ditches or swales must have rip-rap or be paved.
(4) 
The filling, alteration, widening, or any other restriction or alteration of a roadway ditch or swale shall not be permitted without prior written approval of the Village Board.
(5) 
No shrubbery, fence or other such structure shall be planted or constructed in or over any drainage ditch or swale in such a manner which would impede the flow of water and storm runoff through these ditches and swales.
(C) 
Storm drainage structures.
(1) 
Culverts. When allowed, pipe culverts may be used. The minimum length of culverts shall be at least equal to the distance from edge of shoulder to edge of shoulder, plus six times the vertical distance from the edge of should to the flow line of the culvert. No culvert shall have a diameter of less than 12 inches. In no case shall driveway culverts be less than 20 feet in length or more than 24 feet in length without a variance from the Village Board.

(2) 
Bridges. All bridges and culverts having a span of more than 10 feet shall be approved by the Bridge Engineer, Department of Public Works and Buildings, Division of Highway of the State of Illinois.
(3) 
Storm sewers. The sewer system shall be designed by the Rational Method, with self-cleaning velocities as follows: (See Article VI, Division VIII.)
(a) 
That part of the system which serves as main or terminal collectors shall be of sufficient capacity to carry the maximum stormwater flows which may occur in a ten-year period.
(b) 
That part of the system which serves as lateral collectors, and which can readily be augmented by future additions, shall be of sufficient capacity to carry maximum stormwater flows which may occur in a five-year period.
(c) 
The engineer shall select coefficients of runoff based on the types of development anticipated in all parts of the watershed affecting the drainage structure. Information regarding future development of the watershed shall be obtained from the Planning Director.
(d) 
The system shall include all necessary appurtenances such as inlets, catch basins and manholes as may be required for proper operation and maintenance.
(e) 
Where the main storm sewer serving a subdivision can be expected to carry a substantial amount of stormwater from adjoining lands higher in the drainage area, and where the runoff from these lands can be expected to increase in the future because of more intense development, the developer may be permitted to substitute for such sewer an open ditch. Such ditch shall comply with grading, seeding, and sodding specifications of this Code, and such ditch shall be located on a drainage easement of sufficient width to permit its proper maintenance and to allow the eventual construction of an underground storm sewer adequate to serve the entire drainage area above the subdivision.
(f) 
All storm sewers shall be at least 12 inches in diameter and shall be of material and construction approved by the Village Engineer.
(g) 
All materials for the construction of bridges, culverts, storm sewers, catch basins, manholes, inlets and other facilities shall be approved by the Village Engineer.
(4) 
Oversized storm sewers. If greater than twenty-four-inch diameter sewers are required to handle the contemplated flows, the cost of such larger sewers shall be shared between the developer and the Village. The developer shall be responsible for the cost of furnishing and installing a sewer of an appropriate size for his development, and the Village will be responsible for the incremental increase in cost to install the larger sewer.
Dams for water impoundments, pools, ponds, reservoirs, and small lakes shall be planned, designed and constructed under the supervision of a qualified engineer and shall meet the approval of the Department of Conservation of the State of Illinois.
