Approval by development administrator.

(b)

Final plat.

(2)

Major subdivision.

(a)

Preliminary plat approval.

Final plat.

(b)

Subdivision process. All preliminary plats for major subdivisions shall be submitted to the planning commission for review and recommendation, then shall be reviewed by the city council. The planning commission's review shall conclude with a recommendation for approval, recommendation for approval with conditions, or recommendation for disapproval.

(c)

Official submission dates. For the purposes of these regulations, for major subdivisions, the date of the application or the filing by the applicant of the last item of required supporting data, whichever is later, unless such time is extended by mutual consent of the applicant and planning commission, shall constitute the official submission date of the plat on which the statutory period required for formal approval, conditional approval or disapproval of the preliminary or final plat shall commence to run.

(d)

Coordination of flexible zoning application with subdivision approval.

(1)

[Intent.] It is the intent of these regulations that subdivision review be carried out simultaneously with the review of flexible zoning applications under other provisions of this Code. The plans required for flexible zoning applications shall be submitted in a form to satisfy the requirements of these regulations.

(2)

General requirement. Whenever the Code authorizes flexible zoning applications which permit density of buildings and structures different from those which are allowed as of right within the zoning district in which the land is situated, and the application entails the division of land into two or more lots, subdivision approval shall be required in addition to all other procedures and approvals required in this Code. Flexible zoning applications shall include, but not be limited to, all conditional uses and planned development procedures, and shall apply to all such applications, whether before the city council, board of zoning appeals, planning commission or an administrative officer.

(3)

Procedure to be followed.

(a)

Preliminary plat approval required. Whenever a flexible zoning application is submitted which involves a subdivision of land as set forth in subsection 34-12-1(d)(2) of these regulations, the application shall be submitted first to the official authorized to accept the application under the provisions of this Code. The application shall be made on the forms required for a plat and shall include all information required of a preliminary plat application. The development administrator shall then refer the application to the planning commission for preliminary plat approval. The planning commission shall also, when applicable under the provisions of this Code, make such reviews of use, density, and bulk standards as are required under the flexible zoning regulations.

(b)

Referral back for zoning approval. After completing its review, the planning commission shall refer the preliminary plat with its decision of approval, conditional approval or disapproval, together with such recommendations and reviews of use, density, and bulk standards as it was required to make under the flexible zoning regulations of this Code, to the city council. Application shall then be made to the planning commission for final plat approval. No building permits or certificates of occupancy shall be issued for the project until the zoning application has been finally approved and the final plat is recorded with the St. Clair County Recorder of Deeds.

(4)

Resubdivisions of flexible zoning developments.

(a)

A flexible zoning development or land use plan may be subdivided or resubdivided for purposes of sale or lease after the project plan has been finally approved and development completed or partially completed.

(b)

If the subdivision or resubdivision of a flexible zoning development will create a new lot line, the applicant shall make application to the planning commission for review of the subdivision or resubdivision. The planning commission shall recommend approval of the subdivision to the city council only if an amended zoning application also is approved for the flexible development plan, by the appropriate body or official as indicated in this Code, for all provisions governing use, density, and bulk standards.

Completion of improvements. Before the final plat is signed by the mayor, all applicants shall be required to enter into a subdivision improvement agreement with the city.

(b)

Improvement agreement and guarantee.

(1)

Agreement. The applicant shall enter into a subdivision improvement agreement by which the subdivider covenants to complete all required public improvements no later than two years following the date on which the mayor signs the final plat. The applicant shall covenant to maintain each required public improvement for a period of one year following the acceptance by the city council of the dedication of that completed public improvement and also shall warrant that all required public improvements will be free from defect for a period of two years following the acceptance by the city council of the dedication of the last completed public improvement. The subdivision improvement agreement shall contain such other terms and conditions agreed to by the applicant and the city council.

(2)

Covenants to run. The subdivision improvement agreement shall provide that the covenants contained in the agreement shall run with the land and bind all successors, heirs and assignees of the subdivider. The subdivision improvement agreement will be adopted, when necessary, by the city council, pursuant to applicable state and local laws and shall be recorded in the office of the St. Clair County Recorder of Deeds.

(3)

Financial security. The applicant shall provide a letter of credit or cash escrow as financial security for the promises contained in the subdivision improvement agreement. Either financial security shall be in an amount equal to 120 percent of the estimated cost of completion of the required public improvements, including lot improvements. The issuer of the letter of credit or the escrow agent, as applicable, shall be acceptable to the city treasurer.

(a)

Letter of credit. If the applicant posts a letter of credit as financial security for its promises contained in the subdivision improvement agreement, the credit shall:

(i)

Be irrevocable;

(ii)

Be for a term sufficient to cover the completion, maintenance and warranty periods in subsection 34-12-11(b)(1); and

(iii)

Require only that the government present the credit with a sight draft and an affidavit signed by the city attorney attesting to the city's right to draw funds under the credit.

(b)

Cash escrow. If the applicant posts a cash escrow as financial security for its promises contained in the subdivision improvement agreement, the escrow instructions shall provide:

(i)

That the subdivider will have no right to a return of any of the funds except as provided in subsection 34-12-12(b)(2); and

(ii)

That the escrow agent shall have legal duty to deliver the funds to the city whenever the city attorney presents an affidavit to the agent attesting to the city's right to receive funds whether or not the subdivider protests that right.

If and when the city accepts the offer of dedication for the last completed required public improvement, the city shall execute a waiver of its right to receive all but 25 percent of the funds represented by the letter of credit or cash escrow if the subdivider is not in breach of the subdivision improvement agreement. The residual funds shall be financial security for the subdivider's covenant to maintain the required public improvements and its warranty that the improvements are free from defect.

(c)

Temporary improvement. The applicant shall build and pay for all costs of temporary improvements required by the city council and shall maintain those temporary improvements for the period specified by the city council.

Failure to complete improvements. In those cases where a subdivision improvement agreement has been executed and financial security has been posted and required public improvements have not been installed within the terms of the agreement, the city may then:

(1)

Declare the agreement to be in default and require that all the improvements be installed regardless of the extent of the building development at the time the agreement is declared to be in default;

(2)

Suspend final plat approval until the improvements are completed and record a document to that effect for the purpose of public notice;

(3)

Obtain funds under the financial security and complete improvements itself or through a third party;

(4)

Assign its right to receive funds under the financial security to any third party, including a subsequent owner of the subdivision for which improvements were not constructed, in whole or in part, in exchange for that subsequent owner's promise to complete improvements in the subdivision; and

(5)

Exercise any other rights available under the law.

(g)

Acceptance of dedication offers. Acceptance of formal officers of dedication of streets, public areas, easements, and parks shall be by ordinance of the city council. The planning commission may require the plat to be endorsed with appropriate notes to this effect.

(Sec. 12.2.1)

Sec. 34-12-12. - Inspection of improvements.

(a)

General procedure and fees. The city shall provide for inspection of required improvements during construction and ensure their satisfactory completion. The applicant shall pay to the city an inspection fee based on the estimated cost of inspection, and where the improvements are completed prior to final plat approval, the subdivision plat shall not be signed by the mayor unless the inspection fee has been paid at the time of application. These fees shall be due and payable upon demand of the city and no building permits or certificates of occupancy shall be issued until all fees are paid. If the development administrator or his designee finds upon inspection that any one or more of the required improvements have not been constructed in accordance with the city's construction standards and specifications, the applicant shall be responsible for properly completing the improvements.

(b)

Release or reduction of financial security.

(1)

Certificate of satisfactory completion. The city council will not accept dedication of required improvements, nor release nor reduce the amount of any financial security posted by the subdivider until the development administrator or his designee has submitted a certificate stating that all required improvements have been satisfactorily completed and until:

(a)

The applicant's engineer or surveyor has certified to the development administrator or his designee, through submission of a detailed "as-built" survey plat of the subdivision, indicating location, dimensions, materials, and other information required by the development administrator or his designee, that the layout of the line and grade of all public improvement is in accordance with construction plans for the subdivision.

(b)

A title insurance policy has been furnished to and approved by the city attorney indicating that the improvements have been completed, are ready for dedication to the city, and are free and clear of any and all liens and encumbrances. Upon such approval and recommendation by the planning commission, development administrator or his designee, and city attorney, the city council shall thereafter accept the improvements for dedication in accordance with the established procedure.

Sec. 34-12-13. - Escrow deposits for lot improvements.

(a)

Acceptance of escrow funds. Whenever, by reason of the season of the year, any lot improvements required by the subdivision regulations cannot be performed, the development administrator may issue a certificate of occupancy, provided there is no danger to health, safety or general welfare upon accepting a cash escrow deposit in an amount to be determined by the development administrator or his designee for the cost of the lot improvements. The subdivision improvement agreement and financial security covering the lot improvements shall remain in full force and effect.

(b)

Procedures on escrow fund. All required improvements for which escrow monies have been accepted by the development administrator at the time of issuance of a certificate of occupancy shall be installed by the subdivider within a period of nine months from the date of deposit and issuance of the certificate of occupancy. If the improvements have not been properly installed at the end of the time period, the development administrator shall give two weeks written notice to the developer requiring it to install the improvements, and if they are not then installed properly, the development administrator may request the city council to proceed to contract out the work for the installation of the necessary improvements in a sum not to exceed the amount of the escrow deposit. At the time of the issuance of the certificate of occupancy for which escrow monies are being deposited with the development administrator, the developer shall obtain and file with the development administrator prior to obtaining the certificate of occupancy a notarized statement from the purchaser or purchasers of the premises authorizing the development administrator to install the improvements at the end of the nine-month period if the improvements have not been duly installed by the subdivider.

(Sec. 12.2.3)

Sec. 34-12-14. - Maintenance of improvements.

The developer shall be required to maintain all required public improvements on the individual subdivided lots, if required by the development administrator or his designee, until acceptance of the improvements by the city council. If there are any certificates of occupancy on a street not dedicated to the city, the city may on 12 hours notice plow the street or effect emergency repairs and charge those costs to the developer. Following the acceptance of the dedication of any public improvement by the city, the city may, in its sole discretion require the subdivider to maintain the improvement for a period of one year from the date of acceptance.

(Sec. 12.2.4)

Sec. 34-12-15. - Deferral or waiver of required improvements.

(a)

The city council may defer or waive at the time of final approval, subject to appropriate conditions, the provision of any or all public improvements as, in its judgment, are not requisite in the interests of the public health, safety, and general welfare, or which are inappropriate because of the inadequacy or in existence of connecting facilities. Any determination to defer or waive the provision of any public improvement must be made on the record and the reasons for deferral or waiver also shall be expressly made on the record.

(b)

Whenever it is deemed necessary by the city council to defer the construction of any improvement required under these regulations because of incompatible grades, future planning, inadequate or nonexistent connecting facilities, or for other reasons, the subdivider shall pay his share of the costs of the future improvements to the city prior to signing of the final plat by the mayor, or the developer may execute a separate subdivision improvement agreement secured by a letter of credit guaranteeing completion of the deferred improvements upon demand of the city.

(Sec. 12.2.5)

Sec. 34-12-16. - Issuance of building permits and certificates of occupancy.

(a)

When a subdivision improvement agreement and financial security have been required for a subdivision, no certificate of occupancy for any building in the subdivision shall be issued prior to the completion of the required public improvements and the acceptance of the dedication of those improvements by the city, as required in the city council's approval of the final plat.

(b)

The extent of street improvement shall be adequate for vehicular access by the prospective occupant(s) and by police and fire equipment prior to the issuance of an occupancy permit. The developer shall, at the time of the offer of dedication, submit monies in escrow to the city in a sum determined by the development administrator or his designee for the necessary final improvement of the street.

(c)

No building permit shall be issued for the final ten percent of lots in a subdivision, or if ten percent be less than two, for the final two lots of a subdivision, until all public improvements required by the city council for the subdivision have been fully completed and the city has accepted the developer's offer(s) to dedicate the improvements.

(Sec. 12.2.6)

Sec. 34-12-17. - Consumer protection legislation and conflicts of interest statutes.

(a)

No building permit or certificate of occupancy shall be granted or issued if a developer or its authorized agent has violated any federal, state or local law pertaining to:

(1)

Consumer protection;

(2)

Real estate land sales, promotion, or practices; or

(3)

Any applicable conflicts-of-interest legislation with respect to the lot or parcel of land which is the subject of the permit or certificate until a court of competent jurisdiction so orders.

(b)

With respect to any lot or parcel of land described in the immediately preceding section, if a building permit or certificate of occupancy has been granted or issued, it may be revoked by the city until a court of competent jurisdiction orders otherwise, provided that in no event shall the rights of intervening innocent third parties in possession of a certificate of occupancy be prejudiced by any such revocation.

(c)

Any violation of a federal, state, or local consumer protection law, including, but not limited to: Postal Reorganization Act of 1970; the Federal Trade Commission Act of 1970; Interstate Land Sales Full Disclosure Act; the Truth in Lending Act; the Uniform Commercial Credit Code; state "Blue Sky" laws; state subdivision disclosure acts; or any conflicts of interest statute, law or ordinance shall be deemed a violation of these regulations and subject to all of the penalties and proceedings as set forth in article XIII, division 8.

(Sec. 12.2.7)

Sec. 34-12-21. - General improvements.

(a)

Conformance to applicable rules and regulations. In addition to the requirements established in these regulations, all subdivision plats shall comply with the following laws, rules and regulations:

(1)

All applicable statutory provisions.

(2)

The city's Unified Land Development Code, Building and Housing codes, and all other applicable laws of the appropriate jurisdiction.

(3)

The official Comprehensive Plan and official map including all streets, parks, water mains and sewer mains shown on the official map or Comprehensive Plan as adopted.

(7)

Plat approval may be withheld if a subdivision is not in conformity with the above laws, regulations, guidelines and policies as well as the purposes of these regulations established in section 34-1-1 of this Code.

(b)

Adequate public facilities. No preliminary plat shall be approved unless the planning commission determines that public facilities will be adequate to support and service the area of the proposed subdivision. Public facilities and services to be examined for adequacy will include roads and public transportation facilities, sewerage, and water service.

(1)

[Submit information and data.] The applicant for a preliminary plat must, at the request of the planning commission, submit sufficient information and data on the proposed subdivision to demonstrate the expected impact on and use of public facilities and services by said subdivision.

(2)

Comprehensive Plan consistency required. Proposed public improvements shall conform to and be properly related to the city's Comprehensive Plan.

(3)

Water. All habitable buildings and buildable lots shall be connected to a public water system capable of providing water for health and emergency purposes, including adequate fire protection.

(4)

Wastewater. All habitable buildings and buildable lots shall be served by city wastewater collection and treatment.

(5)

Stormwater management. Drainage improvements shall accommodate potential runoff from the entire upstream drainage area and shall be designed to prevent increases in downstream flooding. The city may require the use of control methods such as retention or detention, and/or the construction of off-site drainage improvements to mitigate the impacts of the proposed developments. All proposed subdivision shall comply with the city's stormwater ordinance.

(6)

Roads. Proposed roads shall provide a safe, convenient and functional system for vehicular, pedestrian and bicycle circulation; shall be properly related to the Comprehensive Plan; and shall be appropriate for the particular traffic characteristics of each proposed development and constructed in the manner prescribed by this Code.

(7)

Utilities. All utility facilities, including gas, electric power, telephone, and CATV cables, shall be located underground throughout the subdivision. Underground service connections to the property line of each platted lot shall be installed at the subdivider's expense. (See section 34-12-28.)

(8)

Extension policies. All public improvements and required easements shall be extended through the parcel on which new development is proposed. Streets, water lines, wastewater systems, drainage facilities, electric lines, telecommunications and fiber optic lines shall be constructed through new development to promote the logical extension of public infrastructure. The city may require the applicant of a subdivision to extend off-site improvements to reach the subdivision or oversize required public facilities to serve anticipated future development as a condition of plat approval.

(9)

Easements.

(a)

Unless utilities are to be installed in the public right-of-way, easements not less than seven and one-half feet wide shall be provided on each side of all rear lot lines, and alongside side lot lines where necessary for storm and wastewater sewers; gas, water and other mains; and for underground electric power and telephone lines. Easements of greater width may be required along or across lots when necessary for the extension of main sewers or other utilities or where both water and sewer lines are located in the same easement.

(b)

Adequate easements for storm water drainage shall be established along any natural drainage channel and in such other locations as may be necessary to provide satisfactory disposal of storm water from streets, alleys and all other portions of the subdivision. The location and minimum widths of such easements shall be approved by the development administrator or his designee.

(c)

No person shall deny access to such easements to authorized officials upon display of proper identification.

(d)

No person shall erect any structure or plant any tree or shrub in any easement or within ay street or alley right-of-way, except at the owner's risk with respect to all costs for demolition, removal or reconstruction thereof.

(c)

Restrictive covenants. Restrictive covenants shall be provided for every subdivision including provisions for maintenance of common ground areas. References to those restrictions shall be required to be indicated on the subdivision plat, and the restrictive covenants shall be recorded with the St. Clair County Recorder of Deeds in a form to be approved by the city attorney.

(d)

Plats straddling municipal boundaries. Whenever access to the subdivision is required across land in another municipality, the planning commission may request assurance from the city attorney that access is legally established, and from the development administrator or his designee that access is adequately improved, or that a guarantee has been duly executed and is sufficient in amount to assure the construction of the access road. In general, lot lines should be laid out so as not to cross municipal boundary lines.

(e)

Monuments. The applicant shall place stone or reinforced concrete reference monuments, set in the ground in such a manner that they will not be moved by frost, in accordance with the Plats Act, as now or hereafter amended. (Illinois Compiled Statutes, Chapter 675, section 205/1) Such monuments shall comply with the following requirements.

(1)

All lot corners shall be marked by one-half-inch iron pins not less than 24 inches long. Temporary iron fence posts shall also be placed at these locations and may not be removed until adjacent lots have been built upon.

(2)

All monuments required by these regulations shall be set flush with the ground or so as not to protrude above the ground surface by more than one and one-half inches.

(3)

All monuments shall be properly set in the ground and approved by a registered land surveyor.

(f)

Character of the land. Land that the planning commission finds to be unsuitable for subdivision or development due to flooding, improper drainage, steep slopes, rock formations, adverse earth formations or topography, utility easements, or other features that will reasonably be harmful to the health, safety, and general welfare of the present or future inhabitants of the subdivision and/or its surrounding areas, shall not be subdivided or developed unless adequate methods are formulated by the developer and approved by the planning commission, upon recommendation of the development administrator or his designee, to solve the problems created by the unsuitable land conditions. Such land shall be set aside for uses and shall not involve any danger to public health, safety, and welfare.

(g)

Subdivision name. The proposed name of the subdivision shall not duplicate, or too closely approximate phonetically, the name of any other subdivision in the area covered by these regulations.

(Sec. 12.3.1)

Sec. 34-12-22. - Lots.

(a)

Lot arrangement. The building lot arrangement shall be such that there will be no foreseeable difficulties, for reasons of topography or other conditions, in securing building permits to build on all lots in compliance with all provisions of this Code and health regulations and in providing driveway access to buildings on the lots from an approved street or an existing access easement that was approved prior to the effective date of these regulations.

(b)

Lot dimensions. Lot dimensions shall comply with the minimum standards of this Code. In general, side lot lines shall be at right angles to street lines (or radial to curving street lines) unless a variation from this rule will give a better street or lot plan. Dimensions of corner lots shall be large enough to allow for erection of buildings, observing the minimum front yard setback from both streets. Depth and width of properties reserved or laid out for business, commercial or industrial purposes shall be adequate to provide for the off-street parking and loading facilities required for the type of use and development contemplated, as established by this Code.

(c)

Lot orientation.

(1)

The lot line common to the street right-of-way shall be the front line. All lots shall face the front line and a similar line across the street. Wherever feasible, lots shall be arranged so that the rear line does not abut the side line of an adjacent lot.

(2)

Corner lots shall be configured to accommodate front yards on each street, and may need to be larger than the minimum lot size to accommodate such yards and maintain a sufficient building envelope.

(d)

Double frontage lots and access to lots.

(1)

Double frontage lots. Double frontage and reversed frontage lots shall be avoided except where necessary to provide separation of residential development from traffic arterials or to overcome special disadvantages of topography and orientation.

(2)

Access from principal and minor arterials. Lots shall not, in general, derive access exclusively from a principal or minor arterial. Where driveway access from a principal or minor arterial may be necessary for several adjoining lots, the planning commission may require that such lots be served by a combined access drive in order to limit possible traffic hazards on the street. Lots shall be designed and arranged so that driveways constructed will not require vehicles to back into traffic on arterial streets.

(e)

Soil preservation, grading and seeding.

(1)

Soil preservation and final grading. No certificate of occupancy shall be issued until final grading has been completed in accordance with the approved final plat and the lot pre-covered with soil with an average depth of at least six inches which shall contain no particles more than two inches in diameter over the entire area of the lot, except that portion covered by buildings or included in streets, or where the grade has not been changed or natural vegetation seriously damaged. Topsoil shall not be removed from residential lots or used as spoil, but shall be redistributed so as to provide at least six inches of cover on the lots and at least four inches of cover between the sidewalks and curbs, and shall be stabilized by seeding or planting.

(2)

Lot drainage. All lots shall have a finished grade that will allow the natural flow of surface drainage water from one lot to another without erosion or damage. Grading shall be sloped and tapered at the side and rear lot lines in such a manner as to permit proper drainage.

(3)

Lawn-grass seed and sod. Lawn-grass seed or sod shall be required to be installed on every lot as specified in this paragraph. Sod may be used to comply with any requirement of seeding set forth herein and shall be required for portions of the lot that must be covered by grass when the slope of such area exceeds a slope ratio of 5:1. Lawn-grass seed shall be sown at not less than four pounds to each 1,000 square feet of land area. Seed shall be sown between April 1 and October 31. The seed shall consist of a maximum of ten percent rye grass by weight and minimum of 90 percent permanent bluegrass and/or fescue grass by weight. All seed shall have been tested for germination within one year of the date of seeding, and the date of testing shall be on the label containing the seed analysis. All lots shall be seeded from the roadside edge of the unpaved right-of-way back a distance of 25 feet behind the principal structure on the lot except that existing wooded areas on any lot may be excluded from this requirement. No certificate of occupancy shall be issued until re-spreading of soil and seeding of lawn has been completed; except that between November 1 and March 31, the applicant shall submit an agreement in writing signed by the developer and the property owner, with a copy to the development administrator, that re-spreading of soil and seeding of lawn will be done during the immediate following planting season as set forth in this section, and leave a cash escrow for performance in an amount determined by the development administrator. Sod may be used to comply with any requirement of seeding set forth herein.

(f)

Debris and waste. No cut trees, timber, debris, earth, rocks, stones, soil, junk, rubbish or other waste materials of any kind shall be buried in any land, or left or deposited on any lot or street at the time of the issuance of a certificate of occupancy, and removal of those items and materials shall be required prior to issuance of any certificate of occupancy on a subdivision. No items and materials as described in the preceding sentence shall be left or deposited in any area of the subdivision at the time of expiration of any subdivision improvement agreement or dedication of public improvements, whichever is sooner.

(g)

Waterbodies and watercourses. If a tract being subdivided contains a water body, or portion thereof, lot lines shall be so drawn as to distribute the entire ownership of the water body among the fees of adjacent lots or the ownership of and responsibility for safe maintenance of the water body shall be placed with the homeowners so that it will not become a city responsibility. No part of the minimum area of a lot required under the provisions of this Code may be satisfied by land that is under water. Where a watercourse separates the buildable area of a lot from the street by which it has access, provisions shall be made for installation of a culvert or other structure, of design approved by the development administrator or his designee.

(h)

Subdivision improvement agreement and financial security to include lot improvement. The applicant shall enter into a separate subdivision improvement agreement secured by a letter of credit or cash escrow to guarantee completion of all lot improvement requirements including, but not limited to, soil preservation, final grading, lot drainage, lawn-grass seeding, removal of debris and waste, fencing, and all other lot improvements required by the city council. Whether or not a certificate of occupancy has been issued, the city may enforce the provisions of the subdivision improvement agreement where the provisions of this section or any other applicable law, ordinance, or regulations have not been met.

(Sec. 12.3.2)

Sec. 34-12-23. - Roads.

(a)

General requirements.

(1)

[New construction.] All new streets and alleys shall be constructed solely at the expense of the subdivider/developer in accordance with the requirements set forth herein. New streets and alleys and improvements to existing streets shall be determined based on the typical roadway sections contained in the city's construction specifications. Existing streets that do not meet city standards shall be improved to meet the current street standards by one of the following methods which shall be approved by the city council:

(a)

Existing streets to be upgraded at developer's expense;

(b)

Existing streets will be upgraded with the cost shared between the city and the developer; or

(c)

Off-site road impact fees shall be charged to the developer to cover the costs of the upgrading.

(2)

Frontage on improved roads. No subdivision shall be approved unless the area to be subdivided shall have frontage on and access from an existing street on the official map unless such street is:

(a)

An existing state, county or township highway; or

(b)

A street shown upon a plat approved by the city council and recorded with the office of the St. Clair County Recorder of Deeds. Such street or highway must be suitably improved as required by the highway rules, regulations, specifications or orders, or be secured by a performance bond required under these subdivision regulations, with the width and right-of-way required by these subdivision regulations or the Comprehensive Plan or official map.

Where the area to be subdivided is to utilize existing road frontage, the road shall be suitably improved as provided above.

(3)

Grading and improvements plan. Roads shall be graded and improved and conform to the city construction standards and specifications and shall be approved as to design and specifications by the development administrator or his designee in accordance with the construction plans required to be submitted prior to final plat approval.

(4)

Classification. All roads shall be classified as principal arterials, minor arterials, collectors, subdivision feeders, local access streets or alleys as each are defined in these regulations and shown on the future Thoroughfare Plan map contained in the Comprehensive Plan.

(5)

Topography and arrangement.

(a)

Roads shall be related appropriately to topography. Local access roads shall be curved wherever possible to avoid conformity of lot appearance. All streets shall be arranged so as to obtain as many building sites as possible at, or above, the grades of the streets. Grades of streets shall conform as closely as possible to the original topography. A combination of steep grades and curves shall be avoided. Specific standards are contained in the design standards of these regulations.

(b)

All streets shall be properly integrated with the existing and proposed system of thoroughfares and dedicated rights-of-way as established on the official map and the thoroughfare plan map contained in the Comprehensive Plan.

(c)

All thoroughfares shall be properly related to special traffic generators such as industries, commercial districts, schools, churches and shopping centers; to population densities; and to the pattern of existing and proposed land uses.

(d)

Local access streets shall be laid out to conform as much as possible to the topography to permit efficient drainage and utility systems, and to require the minimum number of streets necessary to provide convenient and safe access to property.

(e)

The rigid rectangular gridiron street pattern is not recommended for residential areas. The use of curvilinear streets, culs-de-sac or U-shaped streets shall be encouraged where such use will result in a more desirable layout.

(f)

Proposed streets shall be extended to the boundary lines of the tract to be subdivided, unless prevented by topography or other physical conditions, or unless in the opinion of the planning commission such extension is not necessary or desirable for the coordination of the layout of the subdivision with the existing layout or the most advantageous future development of adjacent tracts of land.

(g)

In commercial and industrial developments, the streets and other access ways shall be planned in connection with the grouping of buildings, location of rail facilities, provision of alleys, truck loading and maneuvering areas, and walks and parking areas so as to minimize conflict of movement between the various types of traffic, including pedestrian.

(6)

Blocks.

(a)

Blocks shall have sufficient width to provide for two tiers of lots of appropriate depths. Exceptions to this prescribed block width shall be permitted in blocks adjacent to major streets, railroads or waterways.

(b)

The lengths, widths and shapes of blocks shall be such as are appropriate for the locality and the type of development contemplated, but block lengths in residential areas shall not exceed 1,400 feet, nor be less than 500 feet in length. Wherever practicable, blocks along arterial and collector streets shall be not less than 1,000 feet in length.

(c)

In long blocks the planning commission may require the reservation of an easement through the block to accommodate utilities, drainage facilities or pedestrian traffic.

(d)

Pedestrian ways or crosswalks, not less than ten feet wide, may be required by the planning commission through the center of blocks more than 800 feet long where deemed essential to provide circulation or access to schools, playgrounds, shopping centers, transportation or other community facilities. The planning commission may require screening, fencing or additional setbacks from such pedestrian ways. Blocks designed for industrial uses shall be of such length and width as may be determined suitable by the planning commission for prospective users.

(7)

Access to principal arterials. Where a subdivision borders on or contains an existing or proposed principal arterial, the planning commission may require that access to such streets be limited by one of the following means:

(a)

Lots shall back onto the principal arterial and front onto a parallel local street; no access shall be provided from the principal arterial; and screening shall be provided in a strip of land along the rear property line of such lots.

(b)

A series of culs-de-sac, U-shaped streets or short loop streets entered from and designed generally at right angles to such a parallel street, with the rear lines of their terminal lots backing onto the principal arterial.

(c)

A marginal access or service road (separated from the principal arterial by a planting or grass strip and having access at suitable points).

(8)

Road names. Road names shall be sufficiently different in sound and spelling from other road names in the city so as not to cause confusion. A road which is (or is planned as) a continuation of an existing road shall bear the same name. The city clerk shall consult with the St. Clair County 911 Coordinator on proposed road names and receive his recommendation prior to approval of proposed road names by the planning commission.

(9)

Road regulatory signs. The applicant shall deposit with the city at the time of final subdivision approval a sum in an amount adequate to cover the cost of each road sign required by the development administrator or his designee on all roads and at all road intersections. The city shall install all road signs. Street name signs are to be placed at all intersections within or abutting the subdivision, the type and location of which to be approved by the development administrator or his designee.

(10)

Street lights. Street lights shall be provided by the developer at each intersection of two streets (or alleys), at each cul-de-sac, at intervals of approximately 400 feet of street frontage between intersections, and between a street intersection and the terminus of a dead-end street. Additionally, in multiple-family dwelling subdivisions, lighting shall be provided by the developer within parking areas at a minimum rate of one light per 25 parking spaces or any fraction thereof. Street lights shall be installed based on the following standards:

(a)

The design and installation of the street light system in every subdivision/development shall be reviewed by the development administrator or his designee and the appropriate electric utility company. At the subdivider's/ developer's option the appropriate electric utility may design and install the streetlight system.

(b)

The lighting intensity of each streetlight shall be equivalent at a minimum, to a 150 watt high pressure sodium vapor luminaire lamp. Each streetlight standard (post) shall be at least 14 feet high.

(11)

Reserve strips. The creation of reserve strips shall not be permitted adjacent to a proposed street in such a manner as to deny access from adjacent property to the street.

(12)

Construction of roads and dead-end roads.

(a)

Construction of roads. The arrangement of streets shall provide for the continuation of principal streets between adjacent properties when the continuation is necessary for convenient movement of traffic, for effective fire protection, for efficient provision of utilities, and where the continuation is in accordance with the thoroughfare plan. If the adjacent property is undeveloped and the street must temporarily be a dead-end street, the right-of-way shall be extended to the property line. A temporary T- or L-shaped turnaround shall be provided on all temporary dead-end streets, with the notation on the subdivision plat that land outside the normal street right-of-way shall revert to abuttors whenever the street is continued. The planning commission may limit the length of temporary dead-end streets in accordance with the design standards of these regulations.

(b)

Dead-end roads (permanent). Where a road does not extend beyond the boundary of the subdivision and its continuation is not required by the planning commission for access to adjoining property, its terminus shall normally not be nearer to such boundary than 50 feet. However, the planning commission may require the reservation of an appropriate easement to accommodate drainage facilities, pedestrian traffic or utilities. A cul-de-sac turnaround shall be provided at the end of a permanent dead-end street with a minimum right-of-way radius of 50 feet and a minimum pavement radius of 42 feet. For greater convenience to traffic and more effective police and fire protection, permanent dead-end streets shall be limited in length to a maximum of 500 feet.

(13)

Alleys and access easements. Alleys and access easements may be allowed in single-family residential districts only with planning commission approval. Alleys may be required in multiple-family districts and in commercial and industrial districts unless other adequate provisions for service access are made. When required or provided, alleys shall be at least ten feet wide, and shall be paved in accordance with specifications maintained by the development administrator or his designee. Alleys normally shall not intersect with one another nor change sharply in alignment. Adequate vehicular turnaround space shall be paved in accordance with specifications maintained by the development administrator or his designee. Alleys normally shall not intersect with one another nor change sharply in alignment. Adequate vehicular turnaround space shall be provided at the terminus of any rear-end alley.

(14)

Access to subdivisions. It is recommended that all subdivisions be platted with a minimum of two access points to surrounding streets. Subdivisions that will have no more than 50 lots when completed, may be approved with a single entrance. Subdivisions that will have more than 50 lots but not more than 150 lots when completed shall have more than one entrance or shall have a divided entrance. Lots with more than 150 lots but not more than 300 lots shall have a minimum of two entrances. Lots with more than 300 lots when completed shall have a minimum of three entrances and shall be provided an additional entrance for each 150 lots or part thereof over 300 lots. In cases where a divided roadway is utilized, it must provide two divided lanes of traffic, each lane a minimum of 20 feet in width, from the entrance to the subdivision to the intersection of the first through or loop street. The two lanes must be divided by a median planted with grass, shrubs and appropriate trees with the median a minimum of 15 feet in width.

General. In order to provide for roads of suitable location, width and improvement to accommodate prospective traffic and afford satisfactory access to police, fire fighting, snow removal, sanitation and road-maintenance equipment, and to coordinate roads so as to compose a convenient system and avoid undue hardships to adjoining properties, the following design standards for roads are hereby required.

(2)

Minimum right-of-way and pavement widths. Every right-of-way established for subdivision purposes is to be separate and distinct from the lots or parcels adjoining such right-of-way and not included within the dimensions or areas of such lot or parcels. All rights-of-way shall be dedicated to the public by the subdivider. The minimum pavement widths shall be as noted in Table 12-2.

(3)

Excess right-of-way. Right-of-way widths in excess of the standards designated in these regulations shall be required whenever additional width is necessary, due to topography, to provide adequate earth slopes. Such slopes shall not be in excess of three-to-one.

(4)

Road surfacing and improvements. After sewer and water utilities have been installed by the developer, the developer shall construct curbs and gutters and shall surface or cause to be surfaced roadways to the widths prescribed in these regulations. All surfacing shall be of a character as is suitable for the expected traffic and in harmony with similar improvements in the surrounding areas. Types of pavement shall be as determined by the development administrator or his designee. Adequate provision shall be made for culverts, drains and bridges. All road pavement, shoulders, drainage improvements and structures, curbs, turnarounds, and sidewalks shall conform to all construction standards and specifications adopted by city council or the development administrator or his designee, and shall be incorporated into the construction plans required to be submitted by the developer for plat approval.

(5)

Railroads and limited access highways. Railroad rights-of-way and limited access highways where so located as to affect the subdivision of adjoining lands shall be treated as follows:

(a)

In residential districts a buffer strip at least 25 feet in depth in addition to the normal depth of the lot required in the district shall be provided adjacent to the railroad right-of-way or limited access highway. This strip shall be part of the platted lots and shall be designated on the plat: "This strip is reserved for screening. The placement of structures on this land is prohibited."

Notes:

1. Minimum pavement width is measured from back-to-back of curb.

2. Minimum pavement width may increase as needed for left-turn lanes, to be determined by city council.

3. Minimum gradient may be reduced to 0.5 percent where determined necessary by the development administrator.

(b) In districts zoned for business, commercial or industrial uses, the nearest street extending parallel or approximately parallel to the railroad right-of-way shall, wherever practicable, be at a sufficient distance from the railroad right-of-way to ensure suitable depth for commercial or industrial sites.

(c) When streets parallel to the railroad right-of-way intersect a street which crosses the railroad right-of-way at grade, they shall, to the extent practicable, be at a distance of at least 150 feet from the railroad right-of-way. Such distance shall be determined with due consideration of the minimum distance required for future separation of grades by means of appropriate approach gradients.

(6)

Intersections.

(a)

Streets shall be laid out so as to intersect as nearly as possible at right angles. A proposed intersection of two new streets at an angle of less than 75 degrees shall not be acceptable. An oblique street should be curved approaching an intersection and should be approximately at right angles for at least 100 feet therefrom. No more than two streets shall intersect at any one point.

(b)

Proposed new intersections along one side of an existing street shall, wherever practicable, coincide with any existing intersections on the opposite side of such street. Street jogs with centerline offsets of less than 150 feet shall not be permitted, except where the intersected street has separated dual drives without median breaks at either intersection. Where streets intersect major streets, their alignment shall be continuous. Intersection of major streets shall be at least 800 feet apart.

(c)

Minimum curb radius at the intersection of two local streets shall be at least 20 feet and minimum curb radius at an intersection involving a collector street shall be at least 25 feet. Alley intersections and abrupt changes in alignment within a block shall have the corners cut off in accordance with standard engineering practice to permit safe vehicular movement.

(d)

Intersections shall be designed with a flat grade wherever practical. In hilly or rolling areas, at the approach to an intersection, a leveling area shall be provided having not greater than a three percent rate at a distance of 50 feet, measured from the nearest right-of-way line of the intersecting street.

(e)

Where any street intersection will involve earth banks or existing vegetation inside any lot corner that would create a traffic hazard by limiting visibility, the developer shall cut such ground and/or vegetation (including trees) in connection with the grading of the public right-of-way to the extent deemed necessary to provide an adequate sight distance.

(f)

The cross-slopes on all streets, including intersections, shall be three percent or less.

(7)

Pavement structure. All streets and alleys shall be paved across the entire surface width. All streets and alleys shall be paved as indicated below, with the city council or the development administrator or his designee reserving the right to select the most appropriate option; likewise, equivalents to the minimum street construction standards found in Table 12-3 may be approved by the development administrator or his designee depending on engineering and traffic volume considerations.

(a)

Bituminous and/or Portland cement concrete designs based on Illinois Department of Transportation pavement designs is acceptable.

(b)

Earth subgrade.

(i)

Compacted earth per Illinois Department of Transportation standards of 95 percent modified proctor.

(ii)

Compaction test required prior to placing any paving material. The number of tests will be left to the discretion of the development administrator or his designee.

(c)

Portland cement concrete pavement joints shall be sawed longitudinally in center and every 15 feet transversely.

(d)

Materials and construction techniques shall be in accordance with the applicable sections of the latest edition of the Standards and Specifications for Road and Bridge Construction, latest edition, as published by the Illinois Department of Transportation.

(e)

In the event of dispute, Illinois Department of Transportation standards and specifications shall prevail.

(f)

An Illinois registered professional engineer shall be required to certify any pavement design reports, compaction reports, etc., that are required.

(8)

Curb and gutter. All streets, except alleys, private drives, access easements, and commercial or industrial streets, shall be constructed with Portland cement concrete vertical curb and gutter and/or V-type gutter in accordance with the dimensions and specifications shown, therefore, in the city's construction specifications, unless otherwise approved by city council. Only vertical curb and gutter shall be constructed in commercial or industrial streets.

Curb and/or gutter may be constructed either integrally or separately in conjunction with Portland cement pavement. If constructed separately, the gutter flag shall be "tied" to Portland cement concrete pavement with 30-inch long #4 reinforcing bars spaced at 30-inch centers.

(9)

[Structures.] Once a street right-of-way is dedicated to the city, no person may place or install any structure over or into the curb and gutter portion of any city maintained street right-of-way without written permission from the development administrator or his designee.

(c)

Road dedications and reservations.

(1)

New perimeter streets. Street systems in new subdivisions shall be laid out so as to eliminate or avoid new perimeter half-streets. Where an existing half-street is adjacent to a new subdivision, the other half of the street shall be improved and dedicated by the subdivider. The planning commission may authorize a new perimeter street where the subdivider improves and dedicates the entire required street right-of-way width within its own subdivision boundaries.

(2)

Widening and realignment of existing roads. Where a subdivision borders an existing narrow road or when the Comprehensive Plan or official map indicate plans for realignment or widening a road that would require use of some of the land in the subdivision, the applicant shall be required to dedicate those areas for widening or realignment of those roads. The costs of improving the realignment or widening of the road may be shared between the city and the developer upon determination by the city council that the cost of the realignment or widening exceed the cost of providing necessary access to the subdivision. Frontage roads shall be improved and dedicated by the applicant at its own expense to the full width as required by these subdivision regulations. Land reserved for any road purposes may not be counted in satisfying yard or area requirements of this Code whether the land is to be dedicated to the city in fee simple or an easement is granted to the city.

Sec. 34-12-24. - Drainage and storm sewers.

(a)

General requirements. The planning commission shall not recommend approval of any plat of subdivision that does not make adequate provision for storm and flood water runoff channels or basins. The storm water drainage system shall be separate and independent of any wastewater sewer system.

(b)

Nature of storm water facilities.

(1)

Location. The planning commission may recommend and the city council may require the applicant to carry away by pipe or open ditch any spring, surface water or stormwater runoff that may exist either previously to, or as a result of the subdivision to protect the public health, safety, and general welfare. Such drainage facilities shall be located in the road right-of-way where feasible, or in perpetual unobstructed easements of appropriate width, and shall be constructed in accordance with the construction standards and specifications.

(2)

Accessibility to public storm sewers. Where a public storm sewer is accessible, the applicant shall install storm sewer facilities, or if no outlets are within a reasonable distance, adequate provision shall be made for the disposal of storm waters, subject to the specifications of the development administrator or his designee. However, in subdivisions containing lots less than 15,000 square feet in area and in commercial and industrial districts, underground storm sewer systems may be required to be constructed throughout the subdivisions and be conducted to an approved out-fall. Inspection of facilities shall be conducted by the development administrator or his designee.

(3)

Accommodation of upstream drainage areas. A culvert or other drainage facility shall in each case be large enough to accommodate potential runoff from its entire upstream drainage area, whether inside or outside the subdivision. The subdivider's engineer shall calculate the necessary size of the facility, based on the provisions of the construction standards and specifications assuming conditions of maximum potential watershed development permitted by the Comprehensive Plan or other provisions of this Code. Such calculations shall be reviewed, verified, and approved by the development administrator or his designee.

(4)

Effect on downstream drainage areas. The subdivider's engineer shall also study the effect of the subdivision on existing downstream drainage facilities outside the area of the subdivision. City drainage studies together with such other studies as shall be appropriate shall serve as a guide to needed improvements. Where it is anticipated that the additional runoff incident to the development of the subdivision will overload an existing downstream drainage facility, the city council may withhold approval of the subdivision until provision has been made for the expansion of the existing downstream drainage facility. No subdivision shall be approved unless adequate drainage will be provided to an adequate drainage watercourse or facility.

(5)

Areas of poor drainage. Whenever a plat is submitted for an area that is subject to flooding, the city council may approve such subdivision provided that the applicant fills the affected area of the subdivision to an elevation sufficient to place the elevation of streets and lots at a minimum of 12 inches above the elevation of the 100-year floodplain, as determined by the development administrator or his designee. The plat of the subdivision shall provide for an overflow zone along the bank of any stream or watercourse, in a width that shall be sufficient in times of high water to contain or move the water, and no fill shall be placed in the overflow zone nor shall any structure be erected or placed in the overflow zone. The boundaries of the overflow zone shall be subject to approval by the development administrator or his designee.

(6)

Floodplain areas. The city council may, when it deems it necessary for the health, safety, or welfare of the present and future population of the area and necessary to the conservation of water, drainage, and wastewater facilities, prohibit the subdivision of any portion of the property that lies within the 100-year floodplain of any stream or drainage course. These floodplain areas shall be preserved from any and all destruction or damage resulting from clearing, grading, or dumping of earth, waste material, or stumps, except at the discretion of the city council.

(c)

Dedication of drainage easements.

(1)

General requirements. When a subdivision is traversed at or below grade by a watercourse, drainage way, channel or stream, whether natural or man-made, there shall be provided a storm water easement or drainage right-of-way conforming substantially to the lines of such watercourse, and of such width and construction as will be adequate for the purpose. Wherever possible, it is desirable that the drainage be maintained by an open channel with landscaped banks and adequate width for maximum potential volume of flow.

(2)

Drainage easements.

(a)

Perpetual, unobstructed easements at least 15 feet in width for drainage facilities shall be provided across property outside road lines and with satisfactory access to the road. Easements shall be indicated on the plat. Drainage easements shall extend from the road to a natural watercourse or to other drainage facilities.

(b)

When a proposed drainage system will carry water across private land outside the subdivision, appropriate drainage rights must be secured and indicated on the plat.

(c)

Low-lying lands along watercourses subject to flooding or overflowing during storm periods, whether or not included in areas for dedication, shall be preserved and retained in their natural state as drainage ways. Such land or lands subject to periodic flooding shall not be utilized for average density procedures nor for computing the area requirement of any lot.

(d)

Design criteria. A storm water management plan shall be required for any new residential, commercial, industrial, institutional or utility subdivision having a gross aggregate area of one acre or more. The following rules shall govern the design of improvements with respect to managing storm water runoff.

(1)

Drainage and storage facilities shall be designed using the modified rational method or soil conservation service (SCS) method of calculating runoff discharge rate and total volume.

(2)

Storage volume. The volume of storage potential provided in detention facilities shall be sufficient to control the excess storm water runoff, as determined to be the difference between the storm water quality from the site in its developed state for the two-, ten-, 25-, 50-, and 100-year critical duration storm events, less the allowable release rate as set forth in paragraph (d)(3). A higher frequency storm may be justified by the city depending upon the particular development conditions.

(3)

The controlled release rate of storm water runoff from all developments shall be limited to that which existed prior to development.

(4)

Street, blocks, lots, parks and other public grounds shall be located and laid out in such a manner as to minimize the velocity of overland flow and allow maximum opportunity for infiltration of storm water into the ground, and to preserve and utilize existing and planned streams, channels, and detention basins.

(5)

The increase storm water runoff resulting from the proposed development shall be accommodated by the provision of appropriate detention facilities including wet or dry bottom reservoirs, flat roofs, or parking lots.

(6)

All storm water infiltration, retention, and detention facilities shall be provided with an emergency overflow structure or path capable of passing the inflow from a critical duration 100-year storm without damages to any structures of adjacent land. The emergency overflow structure shall have an invert elevation at or above the design high water elevation. A minimum freeboard of one foot shall be provided above the design high water elevation. The freeboard shall be measured from the design high water elevation to the top of the berm.

(7)

All culverts shall extend for the length of the property served and shall not terminate in the middle of a lot.

(8)

Culvert and storm sewer materials and construction shall conform to the applicable sections of the Illinois Department of Transportation Standard Specifications for Road and Bridge Construction, latest edition. Culverts and storm sewers located under paved surfaces shall be reinforced concrete pipe meeting the requirements of AASHTO M170 with rubber gasket joints. Outside of paved areas, high density polyethylene pipe (HDPE) with a smooth interior meeting the requirements of AASHTO M 294 and elastomeric gasket joints in conformance with ASTM F477, or polyvinyl chloride pipe (PVC) meeting the requirements of AASHTO M 278 made with PVC plastic having a minimum cell classification of 12454-C per ASTM D 1784 with elastomeric gasket joints in conformance with ASTM F 477, may be allowed. Polymer coated corrugated metal pipe meeting the requirements of AASHTO M 245, or aluminized steel Type 2 corrugated culvert pipe meeting the requirements of AASHTO M 274 may be allowed for culverts. The minimum diameter for across road culverts shall be 15 inches and shall be designed to convey the runoff associated with the 50-year storm event. The minimum diameter for storm sewers shall be 12 inches and shall be designed to convey the runoff associated with the ten-year storm event. The minimum gradient shall be 0.3 percent. Pipe materials used for the repair and replacement of existing storm sewers and culverts, and for street improvement projects, shall be at the discretion of the city engineer.

(9)

Inlets shall be placed at locations required to handle the run-off associated with the ten-year storm event and wherever necessary so that surface water is not carried across any street or intersection. The maximum permissible encroachment of water on the pavement shall be ten feet.

(e)

Dams and impoundment structure. Dams and berms for water impoundments, pools, ponds, reservoirs and small lakes shall be planned, designed and constructed under the supervision of a registered professional engineer and shall meet the approval of the Division of Water Resources, Illinois Department of Natural Resources. An engineering report shall be submitted to the development administrator on all existing dams within a proposed subdivision. Any dam found to be structurally unsafe shall be reconstructed or reinforced in accordance with the Division of Water Resources standards.

(Sec. 12.3.8)

Sec. 34-12-29. - Public uses.

(a)

Parks.

(1)

Parks. The planning commission shall require that land be reserved for parks and playgrounds or other recreation purposes in locations designated by the Comprehensive Plan or official map. The area shall be shown and marked on the plat, "Reserved for Park and/or Recreation Purposes".

(2)

Park sites. The planning commission shall refer any subdivision proposed to contain a dedicated park to the city council for a recommendation. All land to be reserved for dedication to the city for park purposes shall have prior approval of the city council and shall be shown marked on the plat, "Reserved for Park and/or Recreation Purposes".

(3)

Greenspace requirements for multi-family projects. Multi-family projects shall provide greenspace in an amount determined according to the schedule provided in section 34-12-29(b)(3), with the provision that "number of lots" shall be replaced by "number of units" for the purposes of calculating the minimum greenspace requirement. The requirements for meaningful and accessible layout of greenspace shall also apply to multi-family projects.

(b)

Green space.

(1)

General green space requirements. In every proposed residential subdivision where the gross land area before subdivision exceeds six acres or the proposed subdivision contains 20 or more lots, the developer shall:

(i)

Dedicate or set aside green space for the use of residents in the subdivision. Such green space shall be owned, supervised and managed by the subdivision homeowners' association. All green space areas shall be included on the respective subdivision plats and appropriately integrated into the restrictive covenants for the subdivision.

(ii)

In lieu of green space provided within the subdivision, the applicant may provide a parks in-lieu development fee. This fee shall be paid to the city and be used by the city for the expansion and/ or improvement of existing or future city parks. The in-lieu fee shall be established within the Unified Fee Ordinance and specified in the fee resolutions. This fee may be updated as determined appropriate by the city council.

(2)

Specific requirements for green space within development. The green space shall consist of park, recreation or other green space, whether developed for recreational uses or not, but shall not include nor credit water retention, water detention or other storm water management areas. Every green space area shall be a minimum of 10,000 square feet in size and shall be configured to provide adequate space for meaningful passive or active recreation areas and not be merely remnants of land area not adequate for inclusion in a lot. The active recreational areas required to meet this provision shall not be less than 50 percent of the total area. Active space is defined as playground equipment, picnic tables and facilities, appropriately sized pavilions or other shelters. Passive improvements can include walkways, bikeways, exercise trail, and usable open spaces typical of recreational uses. Not more than 20 percent of the green space may be covered by impervious surfaces including, but not limited to, parking lots, tennis courts, buildings and other structures. Green space must be accessible to all lots via rights-of-way or easements to preclude having to cross private land.

(3)

Minimum green space requirements. The amount of green space provided by a subdivision shall be based on the following schedule:

Number of Lots Required Green Space
Less than 20 (gross land area over 6 acres) 10,000 square feet
20 to 50 lots 500 square feet per lot
51 to 100 lots 25,000 square feet, plus 500 square feet for each lot over 50
101 to 200 lots 47,500 square feet, plus 500 square feet for each lot over 100
More than 200 lots 87,500 square feet, plus 500 square feet for each lot over 200

 

(4)

Cumulative impact of adjacent subdivisions. Developers shall not avoid the green space requirements of this section by configuring proposed subdivisions into smaller parcels or attempting phased developments to avoid setting aside green space. When any parcel over six acres in size is proposed for subdivision into 19 or fewer lots, the gross land area of the proposed lots is less than six acres, and the remaining land is capable of division into two or more lots, the sub-divider shall provide green space in accordance with this section.

(5)

Other green space. The provisions of this section are minimum standards. None of the paragraphs above shall be construed as prohibiting a developer from providing other land for green space purposes in addition to the requirements of this section.

(c)

Other public uses.

(1)

Plat to provide for public uses. Except when an applicant utilizes planned development procedures in which land is set aside by the developer as required by the provisions of this Code, whenever a tract to be subdivided includes recreation uses, or other public use as indicated in any portion of the Comprehensive Plan or official map, the space shall be suitably incorporated by the applicant into its preliminary plat. After proper determination of its necessity by the city council and the appropriate city official of other public agency involved in the acquisition and use of each such site and a determination has been made to acquire the site by the public agency, the site shall be suitably incorporated by the applicant into the preliminary and final plats.

(2)

Referral to city council. The planning commission shall refer the preliminary plat to the city council for its consideration and report. The city council may propose alternate areas for such acquisition and shall allow the public body or agency 30 days for reply. The agency's recommendation, if affirmative, shall include a map showing the boundaries and area of the parcel to be acquired and an estimate of the time required to complete the acquisition.

(3)

Notice to property owner. Upon receipt of an affirmative report, the city council shall notify the property owner and shall designate on the preliminary and final plats that area proposed to be acquired by the public body.

(4)

Duration of land reservation. The acquisition of land reserved by a public agency on the final plat shall be initiated within 12 months of notification, in writing, from the owner that he intends to develop the land. Such letter of intent shall be accompanied by a preliminary plat of the proposed development and a tentative schedule of construction. Failure on the part of the public agency to initiate acquisition within the prescribed 12 months shall result in the removal of the "reserved" designation form the property involved and the freeing of the property for development in accordance with these regulations.

(Sec. 12.3.9; Ord. No. 05-22, § 1, 10-3-05; Ord. No. 12-10, § 1, 5-21-12)

Sec. 34-12-30. - Preservation of natural features and amenities.

(a)

General. Existing features that would add value to residential development or to the city as a whole, such as trees, as herein defined, watercourses, historic spots and similar irreplaceable assets, shall be preserved in the design of the subdivision. No trees shall be removed from any subdivision nor any change of grade of the land affected until approval of the preliminary plat has been granted. Any lot that retains trees should preserve trees of eight-inch caliper or more. When because of setbacks or other lot factors, the footprint of the house requires destruction of more than 25 percent of such trees, a new tree of at least two and one-half-inch caliper size should be planted for each lost tree. All trees on the plat required to be retained shall be preserved, and all trees where required shall be welled and protected against change of grade. The preliminary plat shall show the number and location of existing trees as required by these regulations and shall further indicate all those marked for retention and the location of all proposed street trees required along the street side of each lot as required by these regulations.

(b)

Street trees planted by developer.

(1)

As a requirement of subdivision approval the applicant shall plant street trees on the property of the subdivision. Such trees are to be planted within five feet of the right-of-way of the road or roads within and abutting the subdivision, or, at the discretion of the city council, within the right-of-way of such roads. One tree shall be planted for every 40 lineal feet of frontage along each road unless the city council shall grant a waiver. The waiver shall be granted only if there are trees growing along the right-of-way or on the abutting property which, in the opinion of the city council, comply with these regulations.

(2)

New trees to be provided pursuant to these regulations shall have a minimum caliper of two and one-half inches. Such trees shall be selected from among the species in the definition of approved street tree contained in section 34-2-3.

(c)

Shade tree easement and dedication. The preliminary plat and final plat shall reserve an easement authorizing the city to plant street trees within five feet of the required road right-of-way. No street shall be accepted for dedication until the development administrator or his designee shall inform the planning commission and city council that compliances, where necessary, has been made with these regulations.

(Section 12.3.10)

Sec. 34-12-31. - Preservation of residential subdivision common grounds and green space areas.

Unless the city council determines that exigent circumstances justify otherwise, every existing or future residential subdivision common ground or green space area shall continue to exist on a perpetual basis. This is to ensure the preservation of present and future subdivision common grounds in green space or land devoted to subdivision recreational activities, park-like areas, buffers or other open space in the respective subdivisions.

(a)

Existing and future subdivision common grounds and green space areas shall not be allowed to be split, subdivided or replatted. No subdivision common ground, or any portion thereof, shall be allowed to be combined with or transferred into any other tract of land, platted area or lot. Each subdivision common ground and green space area will continue to exist, on an ongoing basis, as a separate legal entity as it was originally platted in the establishment of the subdivision.

(b)

No residential structures or commercial buildings shall be permitted to be constructed on any subdivision common ground or green space area. Applicable subdivision restrictive covenants for the common grounds and green space areas will apply and govern the ongoing management and maintenance of the subdivision common grounds and green space areas.

(c)

It is envisioned that normally the subdivision common grounds will be established and maintained under the ongoing ownership of an entity of the respective subdivisions. If however, the ownership of a subdivision common ground area is transferred to another third party through a forced sale such as, delinquent taxes or other court ordered action, or any other type of land transfer, the restrictions of this section along with other applicable sections of this Code will continue to apply.

(Sec. 12.3.11)

Sec. 34-12-32. - Non-residential subdivisions.

(a)

General. If a proposed subdivision includes land that is zoned for commercial or industrial purposes, the layout of the subdivision with respect to the land shall make provision as the city council may require. A non-residential subdivision shall also be subject to all other requirements of this Code relative to site design and architectural review. A non-residential subdivision shall be subject to all the requirements of these regulations, as well as such additional standards required by the city council, and shall conform to the proposed land use and standards established in the Comprehensive Plan, official map and all provisions of this Code.

(b)

Standards. In addition to the principles and standards in these regulations, which are appropriate to the planning of all subdivisions, the applicant shall demonstrate to the satisfaction of the planning commission 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 city with respect to street, curb, gutter, and sidewalk design and construction.

(4)

Special requirements may be imposed by the city with respect to the installation of public utilities, including water, sewer, and storm water 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 a permanently landscaped buffer strip when necessary.

(6)

Streets carrying non-residential traffic, especially truck traffic, shall not normally be extended to the boundaries of adjacent existing or potential residential areas.

(Sec. 12.3.12)
