All roadway construction and materials used shall be performed in accordance with the construction methods as listed in the appropriate sections of the State of Wisconsin Department of Transportation Standard Specifications for Road and Bridge Construction, and its supplements, and this chapter, whichever is more restrictive. The design requirements of this section and § 495-43 shall be applicable to all streets and roads that are to be dedicated to the Village, regardless of whether such streets or roads are part of a new subdivision or land division. Design requirements for the pavement shall be adequate for the zoning classification of the area served by the subject street. A street which divides areas with different zoning classifications shall be constructed in accordance with the requirements of the area requiring the higher quality pavement. Any variation of this must have prior approval of the Village Engineer. Combination concrete curb and gutter is required on all streets. (See § 495-27.) A copy of all design assumptions and computations on which the proposed design is based shall be submitted to the Village Engineer.
(2) 
Project costs. All roadway surveys, dedications, plans, specifications, and construction will be at the expense of the applicant. This includes any expense incurred by the Village in the preparation of plans and review and inspection of plans and construction.
(3) 
Preliminary consultation. Prior to the design, preparation, and construction of any roadway to be dedicated to the Village of East Troy, the applicant shall notify the Village Engineer. An on-site meeting with the applicant and the Village Engineer will then be arranged by the Village Engineer. Plans must be provided in order for the Village Engineer to check the design and the drainage.
(4) 
Material slips. Copies of material slips for all materials furnished for the road construction projects shall be delivered to the Village before the Village approves the final construction.
(5) 
Required inspections. Prior to the commencement of any street construction, the subdivider shall notify the Village Engineer at least one workday in advance as to the nature of the work being done. The Village Engineer shall be contacted for required inspections after the following phases of construction: subbase grading; crushed aggregate base course; concrete gutters, curbs and sidewalks; bituminous surface course; and shouldering. Any deficiencies found by the Village Engineer shall be corrected before proceeding to the next phase of construction.[1]
[1]
Editor's Note: Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. II).
(6) 
Tests of materials. The Village reserves the right to obtain a sample of the roadway base material prior to placement on the roadway for purposes of determining whether the material meets gradation and soundness requirements.
(7) 
Pavement samples. Samples of bituminous concrete may be taken by the Village during pavement construction operations for the purpose of determining that the material meets specifications.
B. 
Construction standards. All streets and highways constructed in the Village or to be dedicated to the Village shall fully comply with the following construction standards and shall be adequate for the zoning classifications or projected use of the area served by the street.
(1) 
General. After completion of the underground utilities and approval thereof, the streets shall be constructed. Unless phasing of construction of improvements is approved by the Village Board or its designee, building permits shall not be issued prior to the installation of the street improvements and the approval of an individual lot grading plan that conforms to the guidelines of the master site grading plan, as determined by the Village Engineer or his/her designee.
(2) 
Street rights-of-way. Streets shall have a right-of-way width as established on the Official Map or as designated in § 495-43X; provided, however, that a greater or lesser roadway width may be required by the Village Engineer where necessary to assure uniformity along the entire length of any street.
(3) 
Temporary streets. Construction of temporary streets shall require authorization of the Plan Commission.
(4) 
Standard street improvements.
(a) 
Standard street improvements shall include streetlights, concrete curb and gutter, bituminous base course, bituminous surface course, and, when required, walkways.
(b) 
The construction of standard street improvements can begin only when either the underground utilities were installed in the previous construction season or the construction of underground utilities included mechanical compaction and compaction tests have been approved by the Village Engineer.
(c) 
Upon obtaining the written approval of the Village Engineer, the subdivider can proceed with the construction of the standard street improvements. Standard street improvements shall be installed to the boundary line of the subdivision unless the street culminates in a cul-de-sac, the topography or other physical conditions make it impossible to do so, or unless this requirement is waived, in writing, by the Plan Commission.
(d) 
Where he/she deems appropriate, the Village Engineer may require that pavement construction take place over a two-year period, with the lower coat being placed in the same year as the underground utilities are constructed and with the upper coat being placed in the following year, after thorough cleaning and application of a tack coat to the first coat.
(5) 
Roadway base standards.

(d) 
In the case of commercial, arterial, or other heavy use roads, the Village Board may, in the alternative to the above standards, have the Village Engineer provide specifications for such roads after researching the site and conducting a soil analysis pursuant to Subsection B(8)(c) below.
(e) 
In any case, the Village Board shall have the sole discretion in determining the use and construction classification to be adhered to.
(f) 
In all cases, the base course shall be compacted to the extent necessary to produce a condition so that there will be no appreciable displacement of material laterally and longitudinally under traffic and shall conform to line, grades, and shape shown on the approved plans, profiles, and cross sections.
(g) 
The subdivider shall furnish drawings which indicate the proposed grades of streets shown on the plat and, after approval of those grades by the Village Engineer and adoption by the Village Board, the streets shall be graded to full width of the right-of-way of the proposed street to the subgrade elevations shown on the typical cross section. The grading is to be completed prior to installation of utilities. All stumps and trees which cannot be saved, boulders and other similar items shall be removed by the subdivider.
(6) 
Roadway subgrade quality. If deemed necessary by the Village Engineer, California Bearing Ratio (CBR) tests may be required according to the following standards:
(a) 
All subgrade material shall have a minimum CBR of three. Subgrade material having a CBR less than three shall be removed and replaced with a suitable fill material or the pavement must be designed to compensate for the soil conditions. The soil support CBR values selected for use by the designer should represent a minimum value for the soil to be used.
(b) 
Stable and nonorganic subbase material is required. All topsoil shall be first removed. In addition, all subsoils which have a high shrink-swell potential, low bearing capacity when wet, or are highly elastic shall be removed and used outside of the right-of-way. Where both subsoil and substratum have a high shrink-swell potential and low bearing capacity when wet, an underdrain system shall be installed to keep the water level five feet below the pavement surface. Unstable and organic material must be subcut, removed and replaced with a suitable granular or breaker-run material approved by the Village Engineer.
(7) 
Roadway grading; ditches. Roads shall be graded to their full width in accordance with approved plans, plus an additional distance necessary to establish a four-to-one backslope where ditches are allowed. The roadway shall be compacted and graded to a subgrade using, where necessary, approved fill material in accordance with Wisconsin Department of Transportation standards. Roadside ditches, where allowed by the Village, shall be a minimum of 26 inches below the finished roadway center-line elevation or as approved by the Village Engineer. Debris may not be buried in the designated road right-of-way.

(a) 
All street pavement widths on streets continued from previously developed or platted streets shall, wherever practical, provide for the greater of the existing or required pavement type, existing or required cross section width, same or reduced grade, or same cross slope.
(b) 
Where it is necessary to provide for a transition of pavement width and/or type between new and existing streets, the transition shall occur in a safe manner at an intersection. In the event a transition in pavement width cannot safely occur at an intersection, it shall not occur closer than 250 feet to the intersection of right-of-way lines. In width transitions, the ratio of the transition length to width shall not be less than 15 to one unless the Village Engineer determines that special circumstances prevent use of such ratio, in which case the minimum transition ratio shall be 10 to one.
(15) 
Curb and gutter. Combination concrete curb and gutter is required on all streets. Curb and gutter in residential areas shall have a six-inch barrier curb with a twenty-four-inch flag, except at driveway aprons where depressed curb shall be constructed.

If the street is rejected, corrections shall be made as required by the Village Board, upon the Village Engineer's recommendation, before final inspection can then be made again. If final acceptance is then made, the owner or owners shall dedicate to the Village all land necessary for streets. The subdivider shall warranty the fitness of street improvements for one year after construction.
A. 
Length. As a general rule, blocks in residential areas shall not be less than 600 feet nor more than 1,500 feet in length, unless otherwise dictated by exceptional topography or other limiting factors of good design. A block shall be so designated as to provide two tiers of lots, unless it adjoins a railroad, major thoroughfare, river or park where it may have a single tier of lots. Width of lots or parcels reserved or laid out for commercial or industrial use shall be adequate to provide for off-street service and parking required by the use contemplated and the area zoning restrictions for such use.
B. 
Pedestrian pathways. Pedestrian pathway easements of at least 10 feet wide may be required by the Village Board, upon the recommendation of the Plan Commission, through the center of a block more than 900 feet long, where deemed essential to provide circulation or access to schools, playgrounds, shopping centers, transportation and other community facilities.
C.

The size, shape, and orientation of lots shall be appropriate for the location of the subdivision and for the type of development and use contemplated. The lots should be designed to provide an aesthetically pleasing building site and a proper architectural setting for the buildings contemplated.
(2) 
Area and dimensions of lots shall conform to the requirements of Chapter 510, Zoning, of this Code and in areas not served by public sewer shall, in addition, conform to the requirements of the State Department of Safety and Professional Services. Whenever a tract is subdivided into large parcels, such parcels shall be arranged and dimensioned so as to allow resubdivision of any such parcels into normal lots in accordance with the provisions of this chapter.
B. 
Commercial or industrial lots. Depth and width of properties reserved or laid out for commercial or industrial purposes shall be adequate to provide for the off-street service and parking facilities required by the type of use and development contemplated, as required by Chapter 510, Zoning, of this Code.
C. 
Access. All lots shall have a minimum of 50 feet of platted frontage on a public street to allow access by emergency and service motor vehicles unless part of a planned development approved by the Village Board. Alley frontage (public or private) shall not constitute meeting this minimum frontage requirement. Lots in Business Zoning Districts or Light Industrial Zoning Districts that each have a minimum of 50 feet of platted frontage on a public street are not required to have individual accesses directly onto the public street if access is ensured via a deeded cross-access easement in a form reasonably acceptable to the Village, and if the particular shared access is determined by the Village Board to be in the public interest.
D. 
Lots where abutting arterial highway. Residential lots adjacent to major and minor arterial streets and highways and/or railroads shall be platted with an extra 15 feet of minimum yard setback and shall otherwise be designed to alleviate the adverse effects on residential adjacent lots platted to the major street, highway, railroad, or other such features.
E. 
Corner lots. Corner lots for residential use shall have extra width to permit full building setback from both streets, or as required by applicable zoning regulations.
F. 
Depth. Lots shall have a minimum average depth of 125 feet. Excessive depth in relation to width shall be avoided and a proportion of two to one shall be considered a desirable ratio under normal conditions.
G. 
Width. Width of lots shall conform to the requirements of Chapter 510, Zoning, of this Code, and in no case shall a lot be less than 40 feet in width at the building setback line.
H. 
Side lots. Side lot lines shall be substantially at right angles to or radial to abutting street center lines. Lot lines shall follow Village boundary lines.
I. 
Double and reversed frontage lots. Double frontage and reversed frontage lots shall be avoided except where necessary to provide separation of residential development from traffic arteries or to overcome specific disadvantages of topography and orientation.
J. 
Natural features. In the dividing of any land, regard shall be shown for all natural features, such as tree growth, watercourses, historic spots, or similar conditions which, if preserved, will add attractiveness and stability to the proposed development.
K. 
Land remnants. All remnants of lots below minimum size left over after dividing of a larger tract must be added to adjacent lots or a plan shown as to future use rather than allowed to remain as unusable parcels.
L. 
Large lots. In case a tract is divided and results in parcels of more than twice the minimum lot size provided for by Chapter 510, Zoning, of this Code for the zoning district in which the land is located, such parcels shall be so arranged to permit redividing into parcels in accordance with this chapter and with Chapter 510, Zoning.
M. 
Trunk highway proximity. All lots adjacent to state trunk and federal highways shall be platted with additional depth necessary to provide for a building setback line not less than 50 feet from the nearer right-of-way line or 110 feet from the center line, whichever is more restrictive. The subdivider may appeal this requirement to the Village Engineer. Upon written request of the Village Engineer, the Wisconsin Department of Transportation is hereby authorized to then determine building setback requirements equal to or less than those required above in all land divisions (including certified surveys) adjacent to state and federal highways in accordance with the authority granted in the Administrative Code. The required building setback line and additional lot depth shall be platted so as to accommodate such required building setbacks.
N. 
Easement allowance. Lots containing pedestrian or drainage easements shall be platted to include additional width in allowance for the easement.
O. 
Drainageway and watercourses.
(1) 
Lots abutting upon a watercourse, drainageway, channel, or stream shall have such additional depth or width as required by the Village Engineer to obtain building sites that are not subject to flooding from a post-development one-hundred-year storm.
(2) 
Lands lying between the meander line and the water's edge and any otherwise unplattable lands which lie between a proposed subdivision and the water's edge shall be included as part of lots, outlots or public dedications in any plat abutting a lake or stream.
A. 
Purpose. The following provisions in this section are established to preserve and provide properly located public sites and facilities for drainage and stormwater management as the community develops and to ensure that the costs of providing and developing such public sites are equitably apportioned on the basis of serving the need for the management of increased stormwater quantities resulting from land development.
B. 
Drainage system required.
(1) 
As required by § 495-31, a drainage system shall be designed and constructed by the subdivider consistent with the requirements of Chapter 483, Article II, Post-Construction Stormwater Management, of this Code. A final plat shall not be approved until the subdivider submits plans, profiles, and specifications as specified in this section that have been prepared by a registered professional engineer and approved or modified by the Village Board, upon the recommendations of the Plan Commission and Village Engineer.[1]
[1]
Editor's Note: Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. II).
(2) 
Lots shall be laid out so as to provide positive drainage away from all buildings, and individual lot drainage shall be coordinated with the general storm drainage pattern for the area. Drainage shall be designed so as to avoid concentration of storm drainage water from each lot to adjacent lots.
(3) 
The Plan Commission shall not recommend for approval any subdivision plat which does not provide adequate means for stormwater or floodwater runoff. Any stormwater drainage system will be separate and independent of any sanitary sewer system. Storm sewers, where necessary, shall be designed in accordance with all governmental regulations, and a copy of design computations for engineering capacities shall accompany plans submitted by the planning engineer for the final plat. When calculations indicate that curb capacities are exceeded at a point, no further allowance shall be made for flow beyond that point, and basins shall be used to intercept flow at that point.
C. 
Drainage system plans.
(1) 
The subdivider shall submit to the Village at the time of filing a final plat a drainage plan or engineering report on the ability of existing watercourse channels, storm sewers, culverts, and other improvements pertaining to drainage or flood control within the subdivision to handle the additional runoff which would be generated by the development of the land within the subdivision consistent with the requirements of Chapter 483, Article II, Post-Construction Stormwater Management, of this Code. Additional information shall be submitted to adequately indicate that provision has been made for disposal of surface water without any damage to the developed or undeveloped land downstream or below the proposed subdivision. The report shall also include:[2]
(a) 
Estimates of the quantity of stormwater entering the subdivision naturally from areas outside the subdivision.
(b) 
Quantities of flow at each inlet or culvert.
(c) 
Location, sizes, and grades of required culverts, storm drainage sewers and other required appurtenances.
[2]
Editor's Note: Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. II).
(2) 
A grading plan for the streets, blocks, and lots shall be submitted by the subdivider for the area within the subdivision.
(3) 
The design criteria for storm drainage systems shall be consistent with the requirements of Chapter 483, Article II, Post-Construction Stormwater Management, of this Code.[3]
[3]
Editor's Note: Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. II).
(4) 
Material and construction specifications for all drainage projects (i.e., pipe, culverts, seed, sod, etc.) shall be in compliance with specifications provided by the Village Engineer.
D. 
Drainage system requirements. The subdivider shall install all the storm drainage facilities indicated on the plans required in Subsection C of this section necessary to serve, and resulting from, the phase of the land division under development.
(1) 
All streets shall be provided with an adequate storm drainage system. The street storm system shall serve as the minor drainage system and shall be designed to carry street, adjacent land, and building stormwater drainage. Stormwater shall not be permitted to be run into the sanitary sewer system within the proposed subdivision.
(2) 
The design of the off-street major drainage system shall include the entire watershed affecting the land division and shall be extended to a watercourse or ditch adequate to receive the storm drainage. When the drainage system is outside of the street right-of-way, the subdivider shall make provisions for dedicating an easement pursuant to Subsection F to the Village to provide for the future maintenance of said system.
E. 
Protection of drainage systems. The subdivider shall adequately protect all ditches to the satisfaction of the Village Engineer. Ditches and open channels shall be seeded, sodded or paved depending upon grades and soil types. Generally ditches or channels with grades up to 1% shall be seeded, those with grades up to 4% shall be sodded, and those graded over 4% shall be paved.
F. 
Drainage easements. Where a land division is traversed by a watercourse, drainageway, channel, or stream:
(1) 
There shall be provided a stormwater easement or drainage right-of-way conforming substantially to the lines of such watercourse and such further width or construction, or both, as will be adequate for the purpose and as may be necessary to comply with this section.
(2) 
The watercourse, drainageway, channel, or stream may be relocated in such a manner that the maintenance of adequate drainage will be assured and the same provided with a stormwater easement or drainage right-of-way conforming to the lines of the relocated watercourse and such further width or construction, or both, as will be adequate for the purpose and may be necessary to comply with this section.
(3) 
Wherever possible, drainage shall be maintained in an easement by an open channel with landscaped banks and adequate width for maximum potential volume flow. In all cases, such easements shall be of a minimum width established at the high-water mark or, in the absence of such specification, not less than 30 feet.
(4) 
Whenever a parcel is to be subdivided or consolidated and embraces any part of a drainageway identified on a Village stormwater management plan, comprehensive plan, and/or official map, or any portion thereof, such part of said existing or proposed public drainageway shall be platted and dedicated by the subdivider as an easement or right-of-way in the location and at the size indicated, along with all other streets and public ways in the land division. Whenever any parcel is to be subdivided or consolidated and is part of a drainage district established under the authority of Ch. 88, Wis. Stats., the subdivider shall petition the Circuit Court to transfer the jurisdiction of that portion of the drainage district being subdivided or consolidated to the Village in accordance with § 88.83, Wis. Stats.
G. 
Dedication/preservation of stormwater management facilities. The subdivider shall dedicate sufficient land area for the storage of stormwater to meet the needs to be created by the proposed land development, and in accordance with the standards for on-site detention, and as determined by the Village Engineer. Whenever a proposed stormwater management facility (e.g., detention or retention basin), in whole or in part, is depicted on Village plans, such as the Official Map, as a regional facility within the proposed land division, ground areas for providing the required storage capacity in such proposed public facility shall be dedicated to the public to the requirements of the plan and/or Official Map. Storage areas necessary to serve areas outside the land division shall be held in reserve for a period of five years from the date of final plat approval for future dedication to the Village or other appropriate agency. Storage facilities required and not shown on the Official Map as a regional facility shall be owned and maintained by the subdivider/subsequent owners' association. A maintenance agreement shall be prepared in accordance with the requirements of Chapter 483, Article II, Post-Construction Stormwater Management, of this Code.[4]

Editor's Note: Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. II).
H. 
Storm drainage facilities. The subdivider, at his/her cost, shall install all drainage facilities identified in the required erosion control plan or determined by the Village Engineer as being necessary for the management of all lands and roadways within the development. In addition, drainage capacity through the development from other areas shall be provided in accordance with a comprehensive surface water management study, if applicable. All required storm drainage facilities shall be constructed and operational prior to acceptance of any dedications and/or public improvements served by the storm drainage facilities.
I. 
Minor drainage system. The subdivider shall install all minor drainage system components necessary to reduce inconvenience and damages from frequent storms. Minor drainage components shall include all inlets, piping, gutters, channels, ditching, pumping, and other facilities designed to accommodate the post-development runoff resulting from a ten-year, twenty-four-hour rainfall event as determined in the most current edition of the Natural Resources Conservation Service Technical Release 55 (TR 55). Temporary accumulations of storm runoff from ponding or flowing water, in or near minor system components, shall be permitted provided that such accumulations do not allow the water to flow across the crown of the street from one side to the other. For arterial streets and streets located in commercial districts, ponding within normal traffic lanes (10 feet on each side of the center line of the street) is prohibited. In drainageways and drainageway easements, accumulations of water shall not inundate beyond the limits of the drainageway or drainageway easement. Cross-street drainage channels (valley gutters) shall not be permitted except on cul-de-sac or permanent dead-end streets serving fewer than 10 dwelling units and where the minimum grade in the valley gutter and street gutter between the valley gutter and the next downstream drainage inlet is not less than 1%.[5]
[5]
Editor's Note: Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. II).
J. 
Major drainage system. The subdivider shall install all major drainage system components necessary to reduce inconvenience and damages from infrequent storms. Major system components shall include large channels and drainageways, streets, easements and other paths and shall be capable of accommodating post-development runoff in excess of that accommodated by minor system components resulting from twenty-four-hour rainfall events for storms with return frequencies greater than two years up to and including the one-hundred-year return event (as identified in TR 55). Runoff resulting from a one-hundred-year, twenty-four-hour rainfall event shall be contained within the street right-of-way or designated storm drainage easement or detention facility consistent with the requirements of Chapter 483, Article II, Post-Construction Stormwater Management, of this Code.[6]
[6]
Editor's Note: Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. II).
K. 
Drainage piping systems.
(1) 
Unless otherwise approved by the Village Engineer, all drainage piping of 12 inches diameter and greater in street right-of-way shall be constructed of Class 3 reinforced concrete pipe. Piping materials outside of rights-of-way shall be subject to approval of the Village Engineer. All storm sewer outlets shall be equipped with steel bar or iron pipe debris gates.
(2) 
Agricultural drain tiles which are disturbed during construction shall be restored, reconnected or connected to public storm drainage facilities.
L. 
Open channel systems.
(1) 
Where open channels are utilized in either the minor or major drainage system, they shall be designed so as to minimize maintenance requirements and maximize safety. Drainage easements (in lieu of dedications) shall be utilized to accommodate open channels and provide adequate access by the Village for maintenance of drainage capacity. Side slopes shall not exceed a four-to-one slope. Drainageways, where subject to high groundwater, continuous flows, or other conditions, shall have a paved concrete invert of not less than eight feet wide and side slopes to a point one foot above the channel invert.
(2) 
In areas where invert paving is not required, the drainageway bottom shall be grass. If the drainageway has a bare soil bottom or the natural grasses in the drainageway are disturbed due to development operations, the drainageway bottom shall be sodded and securely staked to one foot above the elevation of inundation resulting from a predevelopment five-year, twenty-four-hour storm event. Other disturbed areas shall be seeded and prepared in accordance with the Village's erosion control requirements (see § 495-35). Velocities for grass-lined channels shall not exceed those presented in the Village's surface water management study, if one is adopted.
M. 
Standards for on-site detention storage. When the subdivider employs on-site detention to control erosion and sedimentation, reduce the post-development peak runoff rate, or temporarily store stormwater runoff due to inadequate downstream drainage facilities, the detention (storage) facilities shall comply with the requirements in Chapter 383, Article II, Post-Construction Stormwater Management, of this Code.[7]
[7]
Editor's Note: Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. II).
A. 
General.
(1) 
If a proposed subdivision includes land that is zoned for commercial or industrial purposes, the layout of the subdivision with respect to such land shall make such provisions as the Village may require.
(2) 
A nonresidential subdivision shall also be subject to all the requirements of site plan approval set forth in the Village Building Code.[1] A nonresidential subdivision shall be subject to all the requirements of this chapter, as well as such additional standards required by the Village, and shall conform to the proposed land use standards established by the Comprehensive Plan, Official Map, and Chapter 510, Zoning, of this Code.
[1]
Editor's Note: See Ch. 210, Building Construction.
B. 
Standards. In addition to the principles and standards in this chapter, which are appropriate to the planning of all subdivisions, the applicant shall demonstrate to the satisfaction of the Village Board that the street, parcel, and block pattern proposed is specifically adapted to the uses anticipated and takes into account other uses in the vicinity. The following principles and standards shall be observed:
(1) 
Proposed industrial parcels shall be suitable in area and dimensions to the types of industrial development anticipated.
(2) 
Street rights-of-way and pavement shall be adequate to accommodate the type and volume of traffic anticipated to be generated thereupon.
(3) 
Special requirements may be imposed by the Village Board, upon the recommendation of the Village Engineer, with respect to street, curb, gutter, and sidewalk design and construction.
(4) 
Special requirements may be imposed by the Village Board, upon the recommendation of the Village Engineer, with respect to the installation of public utilities, including water, sewer, and stormwater drainage.
(5) 
Every effort shall be made to protect adjacent residential areas from potential nuisance from a proposed commercial or industrial subdivision, including the provision of extra depth in parcels backing up on existing or potential residential development and provisions for permanently landscaped buffer strips when necessary.
(6) 
Streets carrying nonresidential traffic, especially truck traffic, shall not normally be extended to the boundaries of adjacent existing or potential residential areas.
The subdivider shall grade each land division in order to establish street, block, and lot grades in proper relation to each other and to topography as follows:
A. 
Master site grading plan.
(1) 
A master site grading plan shall be prepared by the subdivider for all new subdivisions. This plan shall be prepared in accordance with the requirements and standards of the Village.
(2) 
The master site grading plan shall show existing and proposed elevations of all lot corners, control points, and building locations. The plan shall also indicate all overland storm drainage in and adjacent to the subdivision. The cost of the preparation of such a plan shall be paid for by the subdivider.
(3) 
After approval or modification of these plans by the Village Engineer, the full width of the right-of-way of the proposed streets within the subdivision and the entire subdivision lot area shall be graded in accordance with the master site grading plan. The owners of the subdivision lots shall adhere to those plans.
(4) 
Upon completion of all street and subdivision grading, the grades shall be checked and certified by the Village Engineer to determine that the completed grading work is in accordance with the master site grading plan.
(5) 
The cost of all required grading work, supervision, certification, inspection and engineering fees shall be paid for by the subdivider.
B. 
Right-of-way grading. The subdivider shall grade the full width of the right-of-way of all proposed streets in accordance with the approved plans, including the grading of sight triangles at each intersection.
C. 
Block grading. Block grading shall be completed by one or more of the following methods:
(1) 
Regrading along the side or rear lot lines which provides for drainage to the public drainage facilities, provided that any ditches or swales are in public drainage easements, and provided that a deed restriction is adopted which prohibits alteration of the grades within five feet of any property line from the grades shown on the master site grading plan.
(2) 
Parts of all lots may be graded to provide for drainage to a ditch or to a swale.
D. 
Miscellaneous grading requirements.
(1) 
Lot grading shall be completed so that water drains away from each building site toward public drainage facilities at a grade approved by the Village Engineer, and provisions shall be made to prevent drainage onto properties adjacent to the land division unless to a public drainage facility.
(2) 
Grading activities shall not result in slopes greater than four to one on public lands or lands subject to public access.
(3) 
The topsoil stripped for grading shall not be removed from the site unless identified in the required erosion control plan approved by the Village Engineer as not being necessary for erosion control or site landscaping purposes. Topsoil shall be uniformly returned to the lots when rough grading is finished. Topsoil piles shall be leveled and seeded for erosion control prior to the Village releasing the one-year guarantee provision on public improvements in the streets adjacent to the lots on which the topsoil is stockpiled.
(4) 
Such grading shall not result in detriment to any existing developed lands, either within or outside of the corporate limits.
E. 
Drainage flows. The subdivider shall cause to be set upon the master grading plan arrows indicating the directions of drainage flows for each property line not fronting on a street on all parcels and along each street as will result from the grading of the site, the construction of the required public improvements, or which are existing drainage flows and will remain. The arrows indicating the directions of flows shall be appropriately weighted so as to differentiate between the minor and major (one-hundred-year event) drainage components. The arrows shall be accompanied on the master grading plan with the following note. "Arrows indicate the direction of drainage flow in various components resulting from site grading and the construction of required public improvements. The drainage flow components located in easements shall be maintained and preserved by the property owner unless approved by the Village Engineer."
The Village finds that urbanized land uses have accelerated the process of soil erosion, runoff, and sedimentation in the waters of the Village. Therefore, it is declared to be the purpose of this section to control and prevent soil erosion and minimize stormwater runoff increases and thereby to preserve the natural resources, control floods, and prevent impairment of dams and reservoirs, protect the quality of public waters, protect wildlife, protect the tax base, and protect and promote the health, safety and general welfare of the people of the Village. All land disturbing activities shall be subject to the provisions of Chapter 483, Article I, Construction Site Erosion Control, of this Code.
