A. APPLICABILITY

Except as otherwise provided herein, no application for any zoning action under this Ordinance shall be approved, conditionally approved, or denied except in conformance with applicable approval procedures in this chapter and in Tables 2C and 2D.

C. FILING FEES AND RECOVERABLE COSTS

   1.   Application Fee established: All applications shall be accompanied by the applicable, non-refundable Filing Fee in the amount set forth in the annual fee ordinance.
   2.   Recoverable Development Costs:
      a.   Recovery Of Certain Costs Established: Every application filed and processed pursuant to this zoning ordinance that requires the city to incur costs associated with review and approval of the application is subject to the application and, if different, the applicant, are jointly and severally liable for the payment of recoverable costs. By filing an application, the owner and applicant are deemed to have agreed to pay the recoverable costs; provided, however, that the city may require the owner and applicant to enter into an escrow agreement affirming their responsibility for the payment of the recoverable costs.
      The recovery of city costs pursuant to this subsection 2.C.2 are, in addition to all other filing fees and other charges established by the city, as set forth in this code and the annual fee ordinance.
      b.   Recoverable Costs: The following costs incurred by the city in processing an application are recoverable costs for the purpose of this subsection 2.C.2:
         i.   Professional and technical consultant fees, including, without limitation, fees for engineering and plan, landscape, and traffic consultant services that the city determines necessary to review the application;
         ii.   The fees and costs of a hearing officer, if any; and
         iii.   Legal fees, including, without limitation, the city attorney and any additional city-retained attorney or law firm (costs to be measured by their time expended and multiplied by their hourly rate of pay) incurred for services rendered related to the application, including, without limitation, consultation, meeting attendance, and document review, negotiation, and preparation.
      c.   Payment Of Recoverable Costs And Recoverable Cost Escrow:
         i.   Escrow Required: Upon filing an application, the applicant must deposit a cash escrow with the city in an amount to be determined necessary by the community and economic development director to cover the anticipated recoverable costs incurred by the city in reviewing and processing the application. Interest is not payable on the escrow.
         ii.   Charges Against Escrow: From the date of filing of an application, the city will maintain an accurate record of the recoverable costs incurred in the processing of the application. The city may, from time to time, draw funds from the escrow account established for the application to pay the recoverable costs and may transfer such funds to the appropriate city accounts. The city will notify the owner and applicant and maintain an accurate record of all such drawings.
         iii.   Additional Escrow Deposits: Should the community and economic development director at any time determine that the escrow account established for the application is, or is likely to become, insufficient to pay the recoverable costs, the community and economic development director will inform the applicant and require an additional deposit in an amount deemed sufficient to cover foreseeable additional recoverable costs. The community and economic development director may direct that processing of the application be suspended or terminated until the additional amount is deposited into the escrow.
         iv.   Final Settlement: As soon as reasonably feasible following final action on an application, the city will prepare a final accounting of the escrow account in connection with the application and of the actual recoverable costs related to the application and will make a final charge for the actual recoverable costs remaining to be paid. Any remaining funds in the escrow account after the final payment will be returned to the owner or applicant, as applicable. A copy of the final accounting will be provided to the owner and applicant.
         v.   Insufficient Amount For Final Settlement: If the amount in the escrow account is insufficient to pay the total actual recoverable costs, a written demand for payment of the balance due will be mailed to the owner and applicant.
   3.   Condition Of All Applications, Approvals, And Permits: No application filed pursuant to this zoning ordinance will be considered complete unless and until all costs and fees, filing fees and deposits due pursuant to this section 2.C have been paid. Every approval granted and every permit issued pursuant to the zoning ordinance is, whether or not expressly so conditioned, deemed to be conditioned upon payment of recoverable costs and fees as required by this section.
   4.   Tolling Time Periods: Where this zoning ordinance provides that the passage of time without decision or action will be deemed an approval or a recommendation for approval, time periods will be tolled during any period of nonpayment of the recoverable costs and fees and deposits due pursuant ot this section.
   5.   Failure To Pay Recoverable Costs And Fees: Failure to fully pay any incurred recoverable cost, fees, or escrow deposit may requested or denying or revoking any relief sought or issued to the subject property or development.

TRANSITIONAL OFFICE DISTRICT

To provide areas that can accommodate very limited office uses that by virtue of the characteristics listed herein below can serve as an effective transition between single family residential properties, institutional uses, other sensitive uses and either non-residential zoned property and/or arterial streets.
   A.   A small size establishment and small land area requirements
   B.   Low traffic generation
   C.   No outdoor storage, sales or operational requirements
   D.   Lack of noise, odors, and other nuisance type effects potentially objectionable to nearby residential properties
   E.   Maintenance of an aesthetic appearance and scale compatible with nearby residential properties
General Regulations: As provided in Tables 3A and 4C.
Eligibility Regulations: Unless otherwise approved as a variance, no property or group of properties shall be eligible for transitional Office Zoning unless the following requirements are met:
   A.   The property must abut a Single-Family Residential District, and
   B.   Abuts or is across a dedicated right-of way from B2, B4, O1, O2, SD, M1, or M2 District, or is identified on the City of Warrenville Comprehensive Land Use Plan Map for either Office or Office/Research Use, and (Ord. 1817, 3-23-2000)
   C.   The existing structure was originally designed for residential use and has maintained a residential appearance or in the instance of a new structure, all special architectural design standards applicable to the Transitional Office District are satisfied, and
   D.   The property has frontage on and access to an arterial street as designated in the Warrenville Comprehensive Land Use Plan (see appendix A-15 for arterial road listing) unless it is a corner lot, in which case, access shall be permitted to be off the secondary side street.

A. PURPOSE

The intent of this chapter is to provide for the continuation and, under appropriate circumstances, elimination of existing uses of property that do not conform to the requirements of this Ordinance or that may not conform to future amendments thereto.
The provisions herein are designed to accomplish this intent in a way that:
   1.   Recognizes the rights and interests of owners of individual properties that have been rendered nonconforming by City action to upgrade zoning policies and standards;
   2.   Allows the property owner or lessee to recover his or her investment in the Nonconformity, while also recognizing that by virtue of the Nonconformity he or she enjoys a right not generally available to other property owners in the same district; and
   3.   Minimizes the nuisance, reduction in neighboring property values, and other adverse effects of properties that do not conform to their environs.

B. TYPES OF NONCONFORMITIES

A Nonconformity is any characteristic of a structure or lot or parcel of land, or of the use thereof, which was lawful prior to the date of enactment of this Ordinance or any amendment thereto but that does not currently conform to the requirements thereof.
The lawful issuance of a Building Permit prior to the dates specified above shall be considered to establish the lawful nonconforming status of any building or structure.
There are three categories of Nonconformities:
   1. Use Nonconformities
   Use Nonconformities are any activities or functions carried on at a premises (as either a Principal or Accessory Use) that are not allowed by the Permitted and Conditional Uses of the zoning district in which the premises is situated, irrespective of the use for which the premises may have been designed.
   2. Design Nonconformities
   A Design Nonconformity is the design or intended use of all or substantially all of a premises for any Principal or Accessory Use not allowed by the Permitted and Conditional Uses of the zoning district in which it is located, irrespective of the nature of the use or activity currently carried on at that premises.
   3. Standards Nonconformities
   Standards Nonconformities are all other Nonconformities with the requirements of this Ordinance, usually involving failure to conform to the quantitative development standards established herein.

C. ELIMINATION OF NONCONFORMITIES

Properties with Nonconformities shall be lawful uses hereunder and may continue unchanged without time limitation, but changes thereto shall be subject to the provisions of Table 6A.

D. VACANT ADJACENT NONRESIDENTIAL LOTS

Two or more adjacent lots shall be considered as a single lot for zoning purposes if:
1.   All of the lots are in the same ownership, and
2.   All of the lots are vacant, and
3.   One or more of the lots is a legal nonconforming lot of record, and
4.   All of the lots are in the same non-residential district, and
5.   At least one of the other lots abuts a nonconforming lot along a side lot line, or, in the case of a corner lot, along a side or rear lot line.
No division, sale, or use shall be made of any portion of such zoning lot except in conformance with the requirements of this Ordinance and with any approved variance therefrom.

E. ADMINISTRATION

A Certificate of Occupancy shall be required for the continuation of all Nonconformities created by this Ordinance or any amendment thereto.
When the Zoning Administrator determines that a property has any Nonconformity, he or she shall notify the owner or lessee thereof of such Nonconformity and of the applicable regulations.
Such notice shall require that the recipient file with the Zoning Administrator, within 90 days of the date thereof, either satisfactory evidence that the property is not nonconforming or a completed application for a Certificate of Occupancy to continue the Nonconformity.
Upon timely receipt of a complete and accurate application therefor, the Zoning Administrator shall issue a Certificate of Occupancy for the nonconforming property.
The Zoning Administrator shall maintain a file of all Nonconformities of which he or she has sent notice and of all Nonconformities issued Certificates of Occupancy.

8. Nonconforming Lot
Any lot of record as of the effective date of this Ordinance or any applicable amendment thereto that has no substantial structure upon it. See 9 [f] below.
9. Exempted Nonconformities
Any Nonconformities resulting solely from changes in the locations of streets, structures, or uses that are beyond the control of the owner of the property with the Nonconformity, such as a nonconforming setback resulting from a street widening or a Nonconformity resulting from relocation of a structure on an abutting lot in different ownership.
[a]:   These Nonconformities shall be completely eliminated on properties having the type of Nonconformity specified when the specified change to the property is undertaken, except as may be authorized by variance under the provisions of this Ordinance or otherwise explicitly allowed by Table 6A and its footnotes.
[b]:   Provisions shall apply only subject to the Conditions specified.
[c]:   A Minor Reconstruction is repair or reconstruction work on a damaged or destroyed structure that:
   1.   Has a value of less than 50 percent of the cost of constructing the entire building new, based on figures approved by the Zoning Administrator, and
   2.   Is started within 6 months, and completed within 12 months, of the date of the damage, and at no time ceases for more than 60 days before completion.
A Major Reconstruction is any repair or rebuilding that does not qualify as a Minor Reconstruction, including total replacement of a structure that is completely removed with another structure of the same type. If a structure to be replaced has been removed, other than by natural forces, prior to application for a replacement structure hereunder, total elimination of all Nonconformities of the structure shall be required in the replacement structure.
[d]:   Use of land not involving a building, or only incidentally involving one as an accessory use.
[e]:   The elevation of the ground previously covered by a moved structure shall be restored to the grade of the rest of the lot.
[f]:   No variance shall be required to build a single-family dwelling served by public sewers on a nonconforming existing lot of record if lot area, width, and yard dimensions are all 80 percent or more of the minimums required by this Ordinance. No variance shall be required to build a single-family dwelling on a nonconforming existing lot of record not served by public sewers if the lot has been approved for a private sewage disposal system by the DuPage County Health Department within the 6-month period prior to the date of Building Permit Application.
[g]:   No variance is required to build a vertical addition to a nonconforming single-family dwelling as long as the addition does not increase the extent of the nonconformity by further encroaching into the applicable required yard and does not further exceed the height restrictions. (Ord. 1018, 3-11-21) (Ord. O2023-21, 5-15-23)

D. SITE PLAN APPROVAL

No building permit or Certificate of Occupancy shall be issued in any district for any non single-family or non two-family use that involves a change and increase in the intensity of the basic land use occurring on the property (examples include changing from residential to office, residential to institutional, office to restaurant, etc.), increases in the occupant load of the structure, increases in the building footprint of the existing principal structures, increases in the volume of the principal structures, and/or increases in the area of parking lot pavement located on the site without:
   a.   submission of a Site Plan as provided under Site Plan Review in Table 2C; and
   b.   determination by the Zoning Administrator and by the City Council, prior to issuance of any such Permit or Certificate, that such Plan is in compliance with applicable provisions of this and other applicable City ordinances except where variances thereto have been approved as provided therein. Such compliance shall include the provision for, and financial sureties to guarantee the installation of, such public and private improvements as are required by Subdivision Control Ordinance No. 807, whether or not a subdivision of land is proposed.
Neither the Zoning Administrator nor the City Council shall deny any such Permit or Certificate, or make approval thereof subject to conditions, except on the basis of noncompliance of the application therefor with applicable City Ordinances including the City roadway improvement requirements outlined in Section 7-2-3-1 of the City of Warrenville City Code.
The City's review and approval of a Variance, Special Use Permit, and Final PUD Plan shall satisfy the Site Plan Approval Requirements of this Section. (Ord. 2276, 4-18-06)

E. UNLISTED USES

The City Council may, by amendment to the district regulations, allow in any district a use not listed as a Permitted or Special Use in that district if:
   1.   the use is not listed either as a Permitted or Special Use in any district in the Ordinance, and
   2.   the Council deems the use similar in nature to another use listed as a Permitted or Special Use in the same district with respect to:
         a.   types of goods or services produced or sold
         b.   generation of automobile, truck, or pedestrian traffic
         c.   hours of operation
         d.   general effect upon its environs.
Provisions and restrictions herein applicable to the listed use shall also apply to the unlisted use to which it is judged similar. The Zoning Administrator may make a recommendation to the Council on the approval of such uses.

A. PURPOSE

The provisions of this section are intended for special situations in which:
   a.   adequate space, light, air, and other objectives of this Ordinance relating to the public health, safety, and welfare can be achieved without the literal application of the detailed zoning and subdivision requirements otherwise applicable, and
   b.   special amenities and benefits to the community beyond those required by this and other City ordinances can be achieved by allowing more flexible design than is otherwise permitted by such requirements.
These objectives can be achieved where an area of land is planned for development as an integrated unit and where its design is subject to more detailed review and approval by the City than is normally required.
The objective of Planned Unit Development (PUD) is therefore not simply to allow exceptions to otherwise applicable regulations. It is instead to encourage a higher level of design and amenity than it is possible to achieve under the usual land development requirements.
It is accordingly the intent of the City to suspend the application of detailed zoning and subdivision standards as provided herein only where such special amenity is achieved. In this way the City may grant the creative developer a desirable flexibility and at the same time not only protect but enhance the welfare of the residents and other users of a development as well as the rest of the community.

B. QUALIFICATION FOR FILING AS A PUD

Planned Unit Development shall be the only form of development in the SD District. A PUD may also be developed in any other district in which Planned Unit Developments are allowed as Special Uses.
No development shall be filed as a Planned Unit Development unless it is initially under the same ownership or control.
A Planned Unit Development may be residential, commercial, office, industrial, or a combination thereof. Flexibility to suspend requirements imposed elsewhere is not conferred upon the PUD applicant as a matter of right but is in all cases subject to a finding by the City that the objectives of these provisions will be served thereby.

E. APPROVAL PROCESS

(Ord. O2017-26, 5-15-17)
   1.   Preliminary Plans and Final Plans for all Planned Unit Development and General Site Plans for SD Districts (including Development Control Regulations associated therewith) shall be approved only in conformance with the Approval Process provided in Table 2D and other provisions of the Filing Procedures section of this Ordinance and the Approval Criteria provide in Table 8A. No Special Use Permit for a PUD or phase thereof shall be issued before approval by the City Council of a Final Plan as provided herein.
   2.   Notwithstanding anything to the contrary in this Section 8 or in the City Subdivision Control Ordinance No. 807, the City Council may, within its reasonable discretion, authorize the issuance of a "Quick Start" grading and/or infrastructure installation permit at the developer's risk prior to the City Council's approval of the necessary Ordinances required for Final PUD approval of a specific project or development. However, in each such case, the infrastructure which may be installed under a "Quick Start" installation permit shall be limited to those particular infrastructure components which have received final engineering review and approval by the City Council.

A. PURPOSE AND APPLICABILITY

The requirements herein are intended to provide a basis for determining the compatibility of land uses that may produce measurable adverse environmental effects on their surroundings.
They shall apply to all uses in the City and shall be administered as provided under Administration herein. (Ord. 1018, 3-11-21)

C. VIBRATION

Vibration shall not at any time:
   a.   result in a combination of amplitudes and frequencies beyond the "safe" range of U.S. Bureau of Mines Bulletin No. 442, Seismic Effects of Quarry Blasting, Table 7, on any structure, or
   b.   produce an acceleration exceeding 0.1 gravities based on methods of Bulletin 442, or
   c.   be discernible to the human sense of feeling at the property line for 3 minutes or more in any hour.

D. SMOKE

Emissions of smoke shall not exceed the darkness or opacity of Number 0 on the Ringelmann Smoke Chart of the U.S. Bureau of Mines, Information Circular 8333 (revision of IC 7718), May 1, 1967, or of Number 1 for periods not exceeding 4 minutes in any 30-minute period.

F. TOXIC MATTER

Release of any toxic matter is prohibited in concentrations that are detrimental to the public health, safety, comfort, or welfare or that cause damage to property or business. Values given in Tables I, III, IV, and V in Chapter 5 of the latest revision of the Air Pollution Abatement Manual of the Manufacturing Chemists Association shall be used to determine permissible concentrations. Detailed plans for elimination of toxic matter may be required before issuance of a Building Permit.

G. ODOR

Odorous material released shall not exceed the Odor Threshold Concentration at the property line.
Odor shall be measured by Odor Threshold Concentrations with the American Society for Testing and Materials Method D1391-57, Standard Method for Measurement of Odor in Atmospheres (Dilution Method).
Odor shall be measured at ground level and habitable elevation, as defined herein. Detailed plans for elimination of odors crossing property lines may be required before issuance of a Building Permit.

J. HEAT

No heat from operations or processes shall be capable of being sensed at any lot line to the extent of raising the temperature of air or materials more than five degrees Fahrenheit.

K. RADIOACTIVE RADIATION

No operation shall be permitted that causes any individual outside of the lot lines to be exposed to any radiation exceeding the lowest concentration permitted for the general population by federal and state laws and regulations in effect as of the day of application for a Certificate of Occupancy.

L. WASTE

All sewage and industrial wastes shall be treated and disposed of in compliance with regulations of the City, State, and the U.S. Environmental Protection Agency. Approval by the Illinois Environmental Protection Agency shall be required before issuance of any Building Permit.

M. UTILITY FACILITIES

All equipment and facilities used in supplying gas, sewer, water, electric, communication, or governmental utility services of any kind shall be permitted or special uses in accordance with the applicable district regulations.
   1.   All such utility equipment and facilities which are defined in this Ordinance as special public uses shall require site plan approval.
   2.   All wiring (including transmission, distribution and service lines) for the supply of electric and communication services shall be placed underground except as hereinafter provided. Unless otherwise required by City Ordinance, the following wiring is exempt from the underground placement requirement:
      a.   Wiring which carries more than 15,000 volts; or
      b.   Wiring which is for temporary service during the period of new construction; or
      c.   Wiring which is relocated at the request of the City; or
      d.   Wiring which is for minor repair of existing facilities; or
      e.   Lead-in or service wiring from existing poles to single-family dwellings.
   3.   No transformers, utility substations, electric service entrances or gas meters of any buildings (except detached single-family dwellings) shall be visible from any immediately adjacent public street, or from any adjoining residential district at grade level.
Screening may be done in any manner which does not interfere with the operation of or cause equipment or devices to be inaccessible, and shall be the responsibility of the property owner.
   4.   No operation or activity under the control of the property user shall cause or create electromagnetic interference that adversely affects at any point the operation of any equipment other than that belonging to the creator of such interference, or that violates any regulation of the Federal Communications Commission.
With respect to the construction, operation, and maintenance of any public or private electrical utility substation, all reasonable steps shall be taken to reduce and minimize the measurable average annual milligauss level at any property line. For the purpose of this provision, the property owner shall submit to the City a study identifying all available scientific or technical measures used to achieve such a measurable average annual milligauss level. The property owner shall also identify any measure which could reduce the measurable average annual milligauss levels but which was not deemed reasonable. In addition, such study shall include a documented projection of the anticipated measurable average milligauss level at any property line.

L. SCREENING OF REFUSE DISPOSAL AREAS, EXTERIOR GROUND INSTALLED EMERGENCY BACK-UP GENERATORS, GROUND MOUNTED NON-SINGLE FAMILY HVAC EQUIPMENT, AND PRIVATELY OWNED GROUND MOUNTED NON-SINGLE FAMILY ELECTRICAL SWITCH GEAR/TRANSFORMERS

   1.   Refuse Disposal Areas/Enclosures: All non-single family refuse disposal areas shall be screened on all four (4) sides by a solid wood fence or an equivalent material to a height of not less than six (6) feet but not more than eight (8) feet. A 100% enclosed chain link fence with polyethylene "plastic" slats is an acceptable substitute when approved by the Plan Commission. Tall shrubs, evergreen trees and other plantings shall also be provided to soften the aesthetic impact of these areas on adjacent properties and from adjacent public rights-of-way.
   2.   Exterior Ground Installed Emergency Back-up Generators and Non-Single Family HVAC Equipment: A solid screen wall shall be provided around these types of improvements when located in or adjacent to residentially zoned property. Said screen wall shall be of a height equal to or greater than the equipment it is installed to screen. Tall shrubs and evergreen tree landscaping shall be installed to soften the aesthetic and noise impact of these areas on adjacent properties and from adjacent public rights-of-way.
   3.   Exterior Ground Installed Non-Single Family Electrical Switch Gear/Transformers: Tall shrubs, evergreen trees and other plantings shall be provided to soften the aesthetic impact of these areas on adjacent properties and from adjacent public rights-of-way. (Ord. 2276, 4-18-06)

M. INNOVATIVE LANDSCAPING

Innovative landscaping treatments are encouraged and shall be considered as a positive attribute in connection with any request for a variation from the requirements of this Ordinance.

N. SUPERVISION and INSPECTION REQUIREMENTS

The Community Development Director or his/her designated representative at any time before, during, or within 2 (two) years of construction, will make inspections of the site, plant material, installation practices, etc. to determine Developer/Contractor compliance with current guidelines, regulations, and ordinances.

O. CHANGES TO APPROVED LANDSCAPE PLANS

   1.   Any change or deviation to an approved landscape plan, which conforms to this Ordinance, shall require the written approval of the Community Development Director or his/her designated representative.
   2.   Any change or deviation to an approved landscape plan which does not conform to this Chapter shall be subject to the Approval Criteria for Variations outlined in Table 7A of the City of Warrenville Zoning Ordinance and shall be processed in accordance with the Appeals Approval Process for Zoning Applications outlined in Table 2C of the City of Warrenville Zoning Ordinance.

P. VIOLATIONS

The Developer is responsible for the implementation of natural areas protection measures in accordance with the City-approved Landscape Plan. Failure to abide by these measures constitutes a violation of this Ordinance. Such violations include, but are not limited to, the following:

If, as a result of the violation of any provision of this Ordinance, the injury, mutilation, or death is caused to a tree, shrub, or other plant located on City-owned property, the cost of repair or replacement of such tree, shrub, or other plant shall be borne by the party in violation. The replacement value of trees and shrubs shall be determined in accordance with the latest revision of A Guide to Professional Evaluation of Landscape Trees, Specimen Shrubs, and Evergreens, published by the International Society of Arboriculture. (Ord. 1018, 3-11-21)

B. VIOLATION, PENALTY, AND ENFORCEMENT

The Zoning Administrator is hereby designated and authorized to enforce this Ordinance. Upon determining a violation, he or she shall direct the property owner in writing to eliminate the violation within 10 days. Any party that violates any provision of this Ordinance shall upon conviction be fined not less than 50 nor more than 500 dollars for each offense. Each day or portion thereof that a violation exists shall constitute a separate offense.

2. ZONING DISTRICT MAP
The zoning district classification of all land in the City shall be shown on the map designated as the City of Warrenville Zoning District Map. No land shall at any time be classified in more than one zoning district, except that land may be classified in any district designated as an overlay district at the same time it is classified in a district that is not an overlay district.
The Zoning District Map, everything shown thereon, and all amendments thereto shall be as much a part of this Ordinance as if fully described herein and shall be filed as part of this Ordinance by the City Clerk. Said Map shall be available for public inspection in the Community Development Department. Any amendments to this map shall be similarly filed and made available for public reference. (Ord.

3. INTERPRETATION OF DISTRICT BOUNDARIES
District boundary lines shall, unless otherwise clearly indicated on the Zoning District Map, be on the boundary lines of the City, of sections or divisions of sections, or tract or lot lines; on the center lines of streets, railroads, alleys, easements, rivers, and other water bodies; or on the extension of such lines.
District boundary lines approximately following such lines shall be interpreted as located on those lines. Distances not specifically indicated on the map shall be established using the scale of the map.
Where a district boundary divides a lot in single ownership, the district governing any portion of the lot may, at the owner's discretion, be construed as extending to the entire lot if such extension is not more than 25 feet beyond the district boundary on the map.
4. ZONING OF ANNEXED LAND
Except as may be otherwise provided by a pre-annexation agreement or by simultaneous or subsequent amendment to this Ordinance, any parcel of land hereafter annexed to the City shall upon annexation be classified in the R 1 Estate Density Single Family Residential District. (Ord. O2025-05, 2-18-2025)
5. UNZONED AREAS
Public and semi public areas designated on the Zoning District Map without a zoning district classification shall be used only for the use designated on the Map. When such use is permanently discontinued, the property shall be considered to be zoned in the most restrictive district adjacent to the property until an amendment establishing another zoning classification is adopted.

   a.   AIRPORTS WITH APPROACH PLAN
   Maximum height of structures near airports having an Approach Plan approved by the Illinois Department of Aeronautics shall be as provided in such Plan.

4
10,000 Feet and Over
5
 
 
   c.   EXCEPTIONS
   The Zoning Board of Appeals may, after holding a public hearing thereupon, approve an exception to the height restrictions herein on the basis of a finding in an aeronautical study that such exception would not constitute an obstruction to air navigation.
2. NON RESIDENTIAL USES IN OR ADJACENT TO RESIDENTIAL DISTRICTS

When a property zoned O, B or M has only one street line, a single driveway shall be permitted on the adjacent street regardless of the zoning of the underlying or adjacent properties. (Ord. 2098, 11-4-2003)
No new private curb cuts shall be made to City of Warrenville streets or private driveways constructed on City of Warrenville rights-of-way until a permit is issued by the City of Warrenville in accordance with Section 7-2-3-1 of the City Code. (Ord. 2276, 4-18-2006)

Applicants/developers/ property owners are encouraged to participate in additional meetings if major modifications are made to preliminary site plans after they are presented at the initial mandatory public information and input meeting.
   a.   Meeting Purpose: The purposes of mandatory public information and input meetings are to (i) inform interested individuals about what type of non-residential improvements are being proposed on a residentially zoned parcel of property and (ii) solicit input and feedback on proposed site configuration and related development design issues prior to the applicant/developer/property owner committing large sums of time and money into the "final" design drawings for a specific project. It is anticipated that the applicant/owner/developer and City staff will use the input received at these meetings to assist in the preparation and review of final design drawings for the proposed project.

Mandatory public information and input meetings shall begin with the applicant/owner/ developer providing a brief presentation and overview of the proposed project for the public. Immediately following the overview presentation, the applicant/owner/developer, their specialty design consultants, and appropriate City staff members will participate in an informal "open house" meeting to provide additional information, answer specific questions, and receive additional input on the proposed project. The "open house" component of this process will generally occur immediately in advance of the more formal portion of a regular Plan Commission meeting. A formal input form will be provided so that meeting attendees may submit formal written comments, questions or concerns. The applicant/owner/developer is expected to also make a brief presentation of the project to and solicit feedback on proposed project from the Warrenville Plan Commission.
   c.   Meeting Notice Requirements: The applicant/owner/developer shall notify the public of the meeting by posting a public notice sign in compliance with the requirements listed in Section 2.E.1. of this ordinance.

5. PLAN COMMISSION OR ZBA ACTION
The Plan Commission or Zoning Board of Appeals may recommend to the petitioner revisions in the petition that would make it more acceptable. The petitioner may, at his or her discretion, submit a revised petition to the Commission at a continuation of the meeting or hearing without paying an additional filing fee. This provision shall not, however, affect the right of the petitioner to have the original petition without revisions acted upon by the Board, Commission, or City Council.
Within any time limit specified in Tables 2C and 2D, the Plan Commission or Zoning Board of Appeals shall prepare a report consisting of written findings of fact pertaining to the Approval Criteria provided herein for the applicable zoning action together with an action on the application, passed by a majority vote of its members, and any conditions or restrictions to which the action is to be subject. The report shall include the roll call vote on the action.
Except as otherwise provided in Tables 2C and 2D, the action taken by the Commission or Board shall be in the form of a recommendation for final action by the City Council.

6. CITY COUNCIL ACTION
The Plan Commission or Zoning Board of Appeals shall transmit to the City Council its recommendation within the time limit specified in Tables 2C and 2D. The City Council shall not act upon any application requiring a Commission or Board recommendation until either it has received such recommendation or until such time limit has passed.
The Council shall not approve any application unless it finds that the zoning action applied for meets applicable Approval Criteria provided herein. An extraordinary majority vote of all members of the City Council shall be required to approve an application if so provided in Tables 2C and 2D.
Except in the case of an amendment, the Council may make its approval subject to any conditions or restrictions it finds necessary to assure compatibility with the vicinity of the subject property. The Council may also set time limits within which such conditions or restrictions must be complied with or financial guarantees to ensure compliance.

The Zoning Administrator shall advise the applicant in writing of any denial by such body and the reasons, therefore within 5 business days of the decision.
8. REVOCATION OR INVALIDATION
   a.   The Zoning Administrator may revoke any permit or certificate issued hereunder:
      (1)   if the action taken after the permit or certificate is issued is not consistent with plans and information submitted in support of the application therefore; or

The City Council may approve an extension of any time period specified herein. Notwithstanding the foregoing, the use area identified in an SD District Preliminary or Final Plan shall survive the expiration of the preliminary or final plan and the use area so identified shall continue to remain in full force and effect unless otherwise amended as provided in Section 8.F.4.
9. RESUBMISSION
Except as otherwise provided herein, no application that has been denied shall be resubmitted within one year of the date of denial except on the grounds of new factual evidence or a change in conditions found to be valid by the Plan Commission or Zoning Board of Appeals, whichever has initial jurisdiction over the application.

Footnotes to Table 4A
(a)   For Single-Family detached dwellings on newly created lots not served by public sewers, minimum lot area and width shall be 40,000 sf and 140 feet, respectively.
(b)   Minimum lot area for townhouse, single-family attached, and multi-family developments shall in no case be less than 40,000 sf.
(c)   Except single-family detached dwellings in R-6, which shall have 6,000 sf if served by public sewer and 40,000 sf otherwise.
(d)   All principal uses in R-6 except single-family detached dwellings shall be served by public sewer.
(e)   Except for the following uses in R-6:
 
Two-Family
80 feet
Single-Family Detached with Public Sewer
50 feet
 
(f)   Or 10% of the width of the lot, whichever is less.
(g)   Minimum interior side yard width in R-6 shall be:
 
Single-Family Detached
5 feet
Single-Family Attached & Townhouses
10 feet
Two-Family
10 feet
Multi-Family
25 feet
Side yard requirements for attached dwelling units on separate lots shall not apply where the unit is attached to another unit at the side lot line.
 
(h)   Unless otherwise approved by Planned Unit Development, the lot coverage in residential districts shall be as follows:
 
Lot Size
Max Lot Coverage, whichever is greater
>= 30,000 sf.
28% or 9,599 sq. feet
>= 14,000 sf. and < 30,000 sf.
32% or 5,039 sq. ft.
>= 10,000 sf. and < 14,000 sf.
36% or 3,999 sq. ft.
>= 7,000 sf. and < 10,000 sf.
40% or 3,080 sq. ft.
< 7,000 sf.
44% without limitation on the number of square feet
 
   Lot coverage includes principal structures, driveways, and accessory structures, including, without limitation, patios, pools and accessory buildings including, without limitation, garages; provided, however, that pervious pavers, green roofs, and fences shall be excluded from the lot coverage calculations. For the purposes of this footnote (h), the following definitions shall apply:
      “Pervious pavers” means pervious concrete, porous asphalt, permeable pavers or other forms of pervious or porous paving material intended to allow passage of water through the pavement section. It includes an aggregate base that provides structural support and acts as a stormwater reservoir.
      “Green roof” means an engineered roofing system that allows for the propagation of rooftop vegetation and the retention of stormwater while maintaining the integrity of the underlying roof structure and membrane.”
   Whenever the lot coverage would have exceeded the maximum allowable lot coverage but for the exclusion of pervious pavers or green roofs, the property owner must execute and record, at its sole expense, a permeable improvement maintenance agreement and covenant, in the form periodically approved by the City council. The permeable improvement maintenance agreement and covenant must run with the land, bind future owners of the property, require the permeable improvement to be maintained in a first-rate manner, and prohibit the pervious pavers or green roof from being converted to impervious pavers or non-green roof without first obtaining a permit for such conversion from the city.
(i)   Height Bonus: An increase of both minimum required side yard setbacks (or both a side yard and a corner side yard setback on corner lots) of one foot (1') more than the setback required under Table 4A, excluding footnote (f), allows six inches (6'') more of building height up to the maximum height as specified in Table 4A.
(j)   Reserve/Flag lots, enabling access to interior areas of a parcel from a dedicated street only, may be permitted in accordance with the following:
      1.   All lots shall be a minimum of 40,000 sf, exclusive of the portion of the lot used as the reserve strip;
      2.   That each reserve strip providing access to a lot shall be not less than 20 feet in width;
      3.   That not more than three lots consisting of two reserve lots with reserve strips, each 20 feet in width, and one key lot with a frontage of not less than 125 feet wide along the dedicated street shall be permitted;
      4.   That all reserve lots shall be subdivided in accordance with the Subdivision Regulations; and

1. PURPOSE
The purpose of the requirements in this chapter is to further the appropriate provision and design of off-street parking and loading areas that will:
   1.   provide access for occupants, employees, customers, clients, and visitors to land uses in a community dependent on automobile and truck transportation
   2.   foster safe and efficient circulation of vehicles and pedestrians both on private property and on adjacent public streets
   3.   minimize nuisance in residential areas from on- or off-street parking of large numbers of, or incompatible types of, vehicles.
2. APPLICABILITY
Off-street parking and loading spaces shall be provided in conformance with the requirements of Tables 5A, 5B, 5C, 5D, and 5E and other provisions herein for:
   1.   all new uses, and
   2.   all existing uses that are changed so that they are:
      a.   enlarged or expanded, or
      b.   otherwise changed in density, intensity, capacity, or other measure that determines parking or loading requirements hereunder, or
      c.   converted to any other use to which different parking requirements herein apply.
Except that any lawful use existing on the day of effect of this Ordinance, or of any applicable amendment thereto that increases the number of parking or loading spaces required for such use, shall be required to add only the number of spaces equivalent to the difference between the requirements of the Ordinance or amendment for the use after the change and for the use before the change.
The requirements of this chapter apply to any provision, removal, enlargement, or alteration of any off-street parking or loading spaces or areas that are accessory to any building or structure and either:
   1.   are existing as of the effective date of these regulations, or
   2.   are new spaces or areas required to be provided hereunder or voluntarily provided in excess of the requirements herein.
These provisions shall likewise apply to parking that is the Principal Use of a parcel. Open sales lots for motor vehicles shall not be considered as parking spaces for purposes of this chapter.
No additional spaces shall be required for expansion or change of an existing use if the standards herein would require an increase over the spaces already provided on the site of less than 15 percent.
3. PREREQUISITE FOR PERMITS
1.   Building Permit/Zoning Certificate
Prior to issuance of a Building Permit, Zoning Certificate, or Special Use Permit, the Zoning Administrator shall determine that the application therefor exhibits compliance with:
   1.   all applicable provisions of these and other City regulations from which a variance has not been approved as provided therein, and
   2.   all conditions to which any approval thereunder has been made subject.
2.   Certificate of Occupancy
Either prior to issuance of a Certificate of Occupancy or within such period of time thereafter as the Plan Commission may have approved, he or she shall likewise determine either:
   1.   that parking and loading facilities required herein have been fully installed and improved in conformance with:
      a.   all currently applicable approved applications for City permits, certificates, or approvals, and
      b.   any conditions to which approval thereof was made subject, and
      c.   all provisions of this and other applicable City ordinances from which a variance has not been approved, or
   2.   that financial sureties approved by the City Attorney have been provided guaranteeing such installation and improvement.
4. VARIANCES; ADMINISTRATIVE REDUCTIONS
   1.   The City Council may approve a variance to the parking or loading requirements herein on the basis either:
      a.   of criteria provided in the general regulations governing variances in this Ordinance, or

(Ord. 2077, 8-5-03) (Ord. 1018, 3-11-21; Ord. 2023-28, 8-7-2023)
1. PURPOSE
Because of special characteristics of particular properties in the City, the literal application of the provisions of this Ordinance may in certain instances create hardships or practical difficulties not intended by these regulations. The Zoning Board of Appeals may accordingly recommend, and the City Council may grant, variances from the literal application of the provisions of this Ordinance based on findings of fact as provided in this chapter. Variances herein shall be considered the same as variations under the Illinois Revised Statutes.
2. APPROVAL PROCESS
Variances shall be approved only in conformance with the Approval Process provided in the Filing Procedures section of this Ordinance and the Approval Criteria in Table 7A.
3. EXISTING VARIANCES
Any lawful variance previously granted to any lawful use existing on the date of adoption of this Ordinance or any amendment thereto that requires a variance under such Ordinance or amendment, shall be considered a lawful variance without the need for approval of a variance hereunder. Variances shall be transferable and shall run with the land.
Table 7A: Approval Criteria for Variances
In recommending or granting approval or conditional approval of a variance, the Board of Zoning Appeals and the City Council shall prepare written findings of fact that all of the conditions below apply to the application:
1. Special Circumstances
Special circumstances exist relating to the physical character of the property that are peculiar to the property and that do not apply generally to other properties in the same zoning district. And these circumstances are not of so general or recurrent a nature as to make it practical to provide, in the form of an amendment to this Ordinance, a general rule to cover them.
2. Hardship or Practical Difficulties
Because of these special circumstances, the literal application of the provisions of this Ordinance would, without a variance, result in unnecessary and undue hardship or practical difficulties for the applicant, as distinguished from mere inconvenience.
3. Not Resulting from Applicant Action
The special circumstances, practical difficulties, or hardship that are the basis for the variance have not resulted from any act, undertaken subsequent to the adoption of this Ordinance or any applicable amendment thereto, of any party with a present interest in the property.
4. Reasonable Use and Return
Without the requested variance, the property cannot yield a reasonable return, or cannot be reasonably used consistent with the intent of the zoning district and the use of other properties therein, but the purpose of the variance is not otherwise to increase the return from the property or to confer special privileges not ordinarily enjoyed by other properties in the same district.
5. Not Alter Local Character
The variance will not alter the essential character of the locality or substantially impair public safety or welfare or property values in the area.
6. Minimum Variance Needed
The variance approved is the minimum required to allow reasonable use and enjoyment of the property.
1. PURPOSE
To adapt to changing development conditions and provide for the phased implementation of the City Comprehensive Plan, the Plan Commission may from time to time recommend, and the City Council may adopt, amendments to the provisions of the text of this Ordinance, or the Zoning District Map, as provided by the Illinois Revised Statutes.
2. APPROVAL PROCESS
Amendments shall be approved in conformance with the Approval Process provided in the Filing Procedures section of this Ordinance. Map amendments shall be approved only in conformance with applicable Approval Criteria in Table 7B.
Table 7B: Approval Criteria for Zoning Map Amendments (Rezonings)
In recommending approval or conditional approval of a map amendment (rezoning), the Plan Commission shall transmit to the City Council written findings of fact that all of the conditions below apply to the application. In granting approval or conditional approval, the City Council shall similarly find that all of the following conditions apply:
   1. Compatible With Use or Zoning of Environs
   The proposed use(s) or the uses permitted under the proposed zoning classification are compatible with existing uses or existing zoning of property in the environs.
   2. Supported by Trend of Development
   The trend of development in the general area since the original zoning of the affected property was established supports the proposed use of zoning classification.
   3. Consistent With Comprehensive Plan Objectives
   The proposed use or zoning classification is in harmony with the objectives of the Comprehensive Plan of the City as viewed in light of any changed conditions since its adoption.
   4. Furthers Public Interest
   The proposed use or zoning classification promotes the public interest and not solely the interest of the applicant.
1. PURPOSE
Certain uses cannot be allowable generally in a particular zoning district, or in any zoning district, because of the impact their special character creates on surrounding areas.
Some such uses may, however, be allowed under special conditions. These uses are provided for in this Ordinance as Special Uses.
Because a Special Use is compatible with the applicable zoning district only under special conditions, a Special Use Permit is required before any use authorized herein as a Special Use may be established.
Except as specifically provided herein, all regulations of the applicable zoning district, and all other applicable regulations of this and other City ordinances, shall apply to Special Uses.
2. APPROVAL PROCESS
Special Uses shall be approved by the Plan Commission only in conformance with the Approval Process provided in the Filing Procedures section of this Ordinance, the applicable Approval Criteria in Table 7C, and other applicable provisions of this Ordinance.
3. EXISTING USES
Any lawful use existing on the date of adoption of this Ordinance or any amendment thereto that requires Special Use approval under such Ordinance or amendment, shall be considered a lawful Special Use without the need for approval of a Special Use Permit hereunder whether or not a Special Use Permit was ever issued prior to such date. It shall be the responsibility of the user of the property to provide evidence of the existence of the use on or prior to such date.
Any change in the operation of a use that does not conform with conditions attached to a previous and applicable Special Use Permit Approval and all changes from the Approved Special Use Permit involving an increase in the occupant capacity of a structure, in the building footprint, the volume of the structure, or in the area of parking lot pavement on the site subsequent to such Approval date shall require the approval of a new Special Use Permit. (Ord. 2276, 4-18-06)
4. REVIEW OF SPECIAL USES
In evaluating the suitability of a proposed Special Use, the Plan Commission and City Council shall examine the following characteristics of the proposed use and its individual structures or components:
   a.   Location and orientation
   b.   Lot size
   c.   Size of facility, including floor area, structure height, design capacity, and anticipated employment.
   d.   Site design and arrangement
   e.   Provisions affecting on- and off-site pedestrian and traffic movement, vehicle storage, and the passage of emergency vehicles
   f.   Appearance
   g.   Screening or landscaping
   h.   On- or off-site buffering from incompatible uses with open spaces or transitional uses
   i.   Operations factors, such as hours of use or environmental controls
   j.   Other characteristics of the proposed use pertinent in the judgment of the Commission or Council to an assessment of the impact of the use on the area
The Commission may recommend, and the Council may require, such conditions relating to any of the above characteristics as it may judge necessary to allow the use to conform to the Approval Criteria in Table 7C.
The Commission or Council may call upon technical experts or have studies performed to determine specific development standards or conditions for any particular Special Use.
5. EXPANSION OR ALTERATION
A new Special Use Permit shall be required for any existing Special Use that expands its operations in conflict with conditions attached to an existing valid Special Use Permit approval, and/or increases (i) the occupant capacity of the structure, (ii) the building footprint of the structure, (iii) the volume of the structure, or (iv) the area of parking lot pavement on the site. (Ord. 2276, 4-18-06)
Table 7C: Approval Criteria for Special Uses
In recommending or granting approval or conditional approval of a Special Use, the City Council and Plan Commission shall prepare written findings of fact that on the basis of the characteristics cited under Review of Special Uses herein -- or changes to such characteristics that conditions to which the approval is made subject require -- the proposed use will be compatible with existing uses in the area, and with Permitted Uses in the zoning district, in the following ways:
1. Traffic
Any adverse impact of types or volumes of traffic flow not otherwise typical in the zoning district has been minimized.
2. Environmental Nuisance
Any adverse effects of noise, glare, odor, dust, waste disposal, blockage of light or air, or other adverse environmental effects of a type or degree not characteristic of Permitted Uses in the zoning district, have been appropriately controlled.
3. Neighborhood Character
The proposed use will fit harmoniously with the existing natural or man-made character of its surroundings and with Permitted Uses in the zoning district. The use will not have undue deleterious effect on the environmental quality, property values, or neighborhood character already existing in the area or normally associated with Permitted Uses in the district.
4. Public Services and Facilities
The proposed use will not require existing community facilities or services to a degree disproportionate to that normally expected of Permitted Uses in the district, nor generate disproportionate demand for new services or facilities as compared with the Permitted Uses, in such a way as to place undue burdens upon existing development in the area.
5. Public Safety and Health
The proposed use will not be detrimental to the safety or health of the employees, patrons, or visitors associated with the use nor of the general public in the vicinity.
6. Other Factors
The proposed use is in harmony with any other elements of compatibility pertinent in the judgment of the Commission or Council to the particular Special Use or its particular location.

To the extent the SD Development Control Regulations are exceptions from otherwise applicable City ordinances, such exceptions shall be subject to the Approval Criteria in Table 8A Article 7A and Table 7A shall not be applicable to such exceptions. The SD Development Control Regulations shall supersede any provisions of the Zoning Ordinance, Subdivision Ordinance, Landscaping Ordinance, Signage Ordinance, or other City ordinances which are inconsistent with such SD Development Control Regulations. The SD Development Control Regulations, as originally approved or as generally amended thereafter, shall govern all future development and land use in the SD District. A General Amendment to the SD Development Control Regulations shall be proposed as a major amendment. All Preliminary and Final Plans must conform to such SD Development Control Regulations.
Notwithstanding the foregoing, the owner of a lot or development parcel within the SD District may request an amendment of the SD Development Control Regulations as they apply to such lot or development parcel, which request shall be processed as a site-specific major or minor amendment under Article 8.F.4. Requests for exceptions to otherwise applicable City ordinances as part of an SD District General Site Plan or a PUD Preliminary Plan or Final Plan shall also be subject to the Approval Criteria in Table 8A and shall be processed as part of General Site Plan or Preliminary Plan approval or as a major amendment to an approved plan under Article 8.F.4.
1. SITE PLAN REVIEW
Whether or not a land subdivision is involved, Preliminary and Final Plans for the development shall be filed and approved by the City in conformance with the provisions of Table 2D in the Filing Procedures section of this Ordinance.
2. REQUIRED COMMON OPEN SPACE

5. CHANGES ON DEVELOPED RESIDENTIAL LOTS
After initial construction thereon is completed, no Building Permit or Certificate of Occupancy shall be issued for any lot within a Planned Unit Development that is in single-family or two-family use unless:
   a.   The application therefor conforms either to:
      1.   The approved Final Plan, or
      2.   The otherwise applicable district and other zoning regulations herein, or
   b.   A variance from the Plan or the regulations has been approved by the Zoning Board of Appeals as provided herein, and evidence or guarantees satisfactory to the Zoning Administrator of compliance with any conditions to which the approval has been made subject has been submitted.
Table 8A: Approval Criteria for Planned Unit Developments
In recommending approval or conditional approval of a General Site Plan for an SD District Development (including Development Control Regulations associated therewith) or a Preliminary or Final Plan for a Planned Unit Development (PUD), the Plan Commission shall transmit to the City Council written findings of fact that the application meets all of the criteria below or will meet them when the Commission's conditions are complied with. The City Council shall, in granting approval or conditional approval, also find that all of the following criteria are met or will be met when the conditions to which the approval is made subject are complied with:
1. SUPERIOR DESIGN (Ord. 2593 6-21-10)
The PUD represents a more creative approach to the unified planning of development and incorporates sustainable design practices (i.e., Stormwater Management BMPs, LEED and/or LEED-ND certifications), and/or other nationally recognized sustainable design criteria and standards, and a higher standard of integrated design and amenities than could be achieved under otherwise applicable zoning district and subdivision regulations, and solely on this basis modifications to the use and design standards established by such regulations are warranted.
2. MEETS PUD REQUIREMENTS
The PUD meets the requirements for Planned Unit Developments set forth in this Ordinance, and no modifications to the use and design standards otherwise applicable are allowed other than those permitted herein.
3. CONSISTENT WITH CITY PLAN
The PUD is generally consistent with the objectives of the City Comprehensive Plan as viewed in light of any changed conditions since its adoption.
4. PUBLIC WELFARE
The PUD will not be detrimental to the public health, safety, morals, or general welfare.
5. COMPATIBLE WITH ENVIRONS
Neither the PUD nor any portion thereof will be injurious to the use and enjoyment of other properties in its vicinity, seriously impair property values or environmental quality in the neighborhood, nor impede the orderly development of surrounding property.
6. NATURAL FEATURES
The design of the PUD is as consistent as practical with the preservation of natural features of the site such as flood plains, wooded areas, steep slopes, natural drainage ways, or other areas of sensitive or valuable environmental character.
7. CIRCULATION
Streets, sidewalks, pedestrian ways, bicycle paths, off-street parking, and off-street loading as appropriate to the planned land uses are provided. They are adequate in location, size, capacity, and design to ensure safe and efficient circulation of automobiles, trucks, bicycles, pedestrians, fire trucks, garbage trucks, and snow plows as appropriate without blocking traffic, creating unnecessary pedestrian-vehicular conflict, creating unnecessary through traffic within the PUD, or unduly interfering with the safety or capacity of adjacent streets.
8. OPEN SPACES AND LANDSCAPING
The quality and quantity of public and common open spaces and landscaping provided are consistent with the higher standards of design and amenity required of a PUD. The size, shape, and location of a substantial portion of total public and common open space provided in residential areas render it useable for recreation purposes.
Open space between all buildings is adequate to allow for light and air, access by fire fighting equipment, and for privacy where walls have windows, terraces, or adjacent patios. Open space along the perimeter of the development is sufficient to protect existing and permitted future uses of adjacent property from adverse effects from the development.
9. COVENANTS
Where individual parcels are to be later sold, adequate provision has been made in the form of deed restrictions, homeowners or condominium associations, or the like for:
   a.   the preservation and maintenance of any open spaces, thoroughfares, utilities, water retention or detention areas, and other common elements not to be dedicated to the City or another public body
   b.   such control of the use and exterior design of individual structures, if any, as is necessary for continuing conformance to the PUD Plan, such provision to be binding on all future ownership.
10. PUBLIC SERVICES
The land uses, intensities, and phasing of the PUD are consistent with the anticipated ability of the City, the school districts, and other public bodies to provide and economically support police and fire protection, water supply, sewage disposal, schools, and other public facilities and services without placing undue burden on existing residents and businesses.
11. PHASING
Each development phase of the PUD can, together with any phases that preceded it, exist as an independent unit that meets all of the foregoing criteria and all other applicable regulations herein even if no subsequent phase should ever be completed. The provision and improvement of public or common area improvements, open spaces, and amenities--or the provision of financial sureties guaranteeing their improvement--is phased generally proportionate to the phasing of the number of dwelling units or amount of non-residential floor area. (Ord. 1018, 3-11-21; amd. Ord. O2022-13, 4-18-2022)
1. MAXIMUM SOUND LEVELS
No operation or activity shall cause or create noise above the sound pressure levels in Tables 9A and 9B at the locations specified therein.
2. MEASUREMENT
A sound level meter and associated octave band analyzer conforming to the specifications of the American Standards Association shall be employed to measure the intensity and frequency of sound.
3. EXEMPTIONS
The following shall be exempt from noise performance standards:
   a.   Noises of construction or maintenance activities from 7 AM to 9 PM.
   b.   Noises of safety signals, warning devices, and emergency pressure relief valves.
   c.   Transient noises of moving sources such as transportation vehicles.
   d.   Noises associated with snow plowing, street sweeping, and mosquito abatement.
   e.   Church bells, chimes, and carillons.
   f.   Other noises not under the direct control of the property user.

The rate of emission of particulate matter from all sources at any point shall not exceed 0.1 grains per cubic foot of the conveying gas or air. For measurement of particulate matter in gases resulting from combustion, standard corrections shall be applied to a stack temperature of 500 degrees Fahrenheit and 50 percent excess air.
2. CONTROL OF WIND EROSION
Emission of particulate matter from materials, products, or surfaces subject to wind erosion shall be minimized by paving, oiling, wetting, covering, landscaping, fencing, or other means.
This shall apply to vacant lots; unpaved roads; yards and storage piles of bulk materials such as coal, sand, cinders, slag, and sulfur; and similar sources of windborne particulates.
1. OTHER REGULATIONS APPLICABLE
In addition to the requirements herein, all materials regulated in this section shall be utilized, stored, manufactured, and handled in accordance with the City Fire Code (Title 8, Chapter 3, of the Warrenville Municipal Code) and the standards of the National Fire Protection Association.
2. DETONABLE MATERIALS

[a]   The Community Development Director, with the prior written approval of the City Engineer, shall have the administrative authority to approve illumination plans that provide illumination levels other than those listed inTable 9C. (Ord. 1917, 6-20-01)
[b]   Except gasoline station canopies, for which the average illumination may not exceed 20 F/C and the maximum illumination may not exceed 30 F/C; provided, however, for legally non- conforming gasoline station canopies where the light fixtures are not earlier replaced, the maximum average illumination may not exceed 60 F/C until January 1, 2028 pursuant to Section Table 6A of this Code. After January 1, 2028, for all gas station canopy lighting, the maximum average illumination may not exceed 20 F/C and the maximum illumination may not exceed 30 F/C.
[c]   All existing fixtures legally nonconforming to these regulations must be updated to current illumination standards by January 1, 2028.
[d]   Fixtures may be equipped with dimming devices to reduce lighting to no less than 0.8 F/C.
For the purpose of this section, the following guidelines shall be used to determine the activity level for individual parking lots:
   A.   HIGH ACTIVITY LEVELS:
      Includes high intensity Motorist Service and General Manufacturing uses including, but not limited to, athletic arenas, regional shopping centers with retail space above 300,000 square feet, entertainment theaters, gas stations, and fueling centers.
   B.   MEDIUM ACTIVITY LEVELS:
      Includes Motorist Service uses, mixed uses, and moderate intensity General Manufacturing uses.
   C.   LOW ACTIVITY LEVELS:
      Includes Community Retail uses, churches, schools, and neighborhood recreational facilities, Light Manufacturing uses with modest nighttime uses or lighting requirements, and multi-family residential developments. (Ord. 2276, 4-18-06; amd. Ord. 2023-28, 8-7-2023)
2. FIXTURE SPECIFICATIONS
All exterior luminaries, except decorative fixtures as approved by the Plan Commission, shall have full horizontal cutoff optics with zero intensity at or above horizontal (90 degrees) with flat lenses, with no portion of the lens protruding below the housing, without the option to tilt. All installations shall have a Correlated Color Temperature (CCT) of no greater than 4000 K. Standard City of Warrenville decorative streetlight fixtures shall be exempt from this regulation.
All parking lot lighting shall be equipped with and operated on a timer or other equivalent City approved system to substantially reduce the amount of parking lot lighting provided during times and periods when the parking lot is not normally used. The required photometric plan for such parking lots shall clearly reference and accommodate the installation of this type of system. (Ord. 2276, 4-18-06; amd. Ord. 2023-28, 8-7-2023)
3. MOUNTING HEIGHT SPECIFICATIONS
Parking lots adjacent to or across from detached and attached Single-Family zoned properties shall have a maximum light fixture mounting height of 26-feet.

   (b)   All lighting shall be of a residential character and shielded or directed to minimize perceived glare on surrounding residential properties. (Ord. 2023-28, 8-7-2023)
1. NEW USES
An application for a Special Use Permit or a Building Permit for an industrial use within any Manufacturing District shall include a certification by a licensed engineer or scientific laboratory that the use involved in the application is able to meet all applicable Performance Standards to the extent that this can be judged based on the submitted building plans and other information available prior to construction.
This certification shall be accompanied by copies of all data or information supplied by the applicant and used as the basis of the certification. The Zoning Administrator may refer the certification and data to the City Engineer for review.
The Zoning Administrator may also require such certification for a land use in any other zoning district when in his or her judgment the use has potential to exceed any Performance Standard herein. Such certification may include all Performance Standards or only individual Standards specified by the Zoning Administrator.
2. EXISTING USES
In enforcing Performance Standards on existing uses, the Zoning Administrator may issue a written Notice of Violation to an alleged violator. The Zoning Administrator shall, before issuing such Notice, make technical determinations of violation when such determinations can be made using equipment and trained personnel normally available to the City or obtainable without extraordinary expense.
In other cases, however, technical complexity or extraordinary expense may make it unreasonable for the City to maintain personnel or equipment for making determinations of violation prior to issuing a Notice of Violation. In such cases, a Notice of Violation may be issued when the Zoning Administrator has other reason to believe there is probable violation. The Zoning Administrator shall give Notice of Violation by any means that ensures a signed receipt for such notice to the party responsible for the alleged violation.
The notice shall describe the alleged violation and the results of technical determinations or the other reasons why the Zoning Administrator believes there is a violation. The notice shall require either an answer or correction of the alleged violation to the satisfaction of the Zoning Administrator and within a time limit he or she shall specify in the Notice.
The Notice shall also state that failure to provide an answer or correct the alleged violation within this time limit shall constitute admission of a violation.
The Notice shall further state that, if technical determinations have not already been made, upon request of the alleged violator such determinations will be made. If a violation is found as a result of such determinations, the cost of the determinations will be assessed against the properties or parties responsible in addition to any other penalties provided for. If no violation is found, the City will pay the cost of the determinations.
1. GENERAL PROVISIONS
A. Compatibility
Accessory uses and structures shall be compatible with the principal use of the lot on which they are located and shall not be established prior to the establishment of the principal use.

10. LANDSCAPE MAINTENANCE PLAN AND CALENDAR
A detailed site landscape maintenance plan and calendar shall be prepared by a qualified landscape architect or designer and submitted to the City for review and approval. (Ord. 2770, 4-3-13)
1. SELECTION
Planting materials used in conformance with the provisions of this Section shall be of good quality, species normally grown in Northeastern Illinois, and capable of withstanding the extremes of individual site microclimates. Size and density at the time of planting and at maturity are additional criteria which must be considered when selecting plant materials. See the Arboricultural and Open Space Manual for recommended and unacceptable plant materials. Plants which clearly show signs of disease shall not be permitted and must be replaced at the owner's expense.
   a.   Shade Trees
      All shade trees shall have a minimum trunk size of 2-1/2 (two and one-half) inches in diameter as measured one foot above the established ground level upon installation.
   b.   Ornamental Trees
      Ornamental trees should be used, especially in small areas. These trees shall have a minimum trunk size of 2 (two) inches in diameter as measured one foot above the established ground level upon installation, or be a clump form at a height of at least 7-8 (seven to eight) feet.
   c.   Evergreen Trees
      Evergreen trees should be incorporated into the landscape treatment of a site, particularly in those areas screening parking lots from dedicated public rights-of-way or property zoned for residential use. All evergreen trees shall have a minimum height of 6 (six) feet at planting.
   d.   Shrubs
      Shrubs should be used extensively throughout the development. Shrubs shall be a minimum of 2-1/2 (two and one-half) feet in height when measured after planting, except for dwarf shrubs which do not reach this height at maturity. Dwarf shrub size shall be approved by the Community Development Director. Hedges shall be planted and maintained so as to form a continuous, unbroken, solid visual screen within 1 (one) year after time of planting.
2. INSTALLATION
All landscaping materials shall be installed in accordance with the planting procedures set forth in the Arboricultural and Open Space Manual.
3. MAINTENANCE
   a.   Responsibility
      The owner of the premises shall be responsible for the maintenance, repair and replacement of all landscaping materials and barriers, including refuse disposal areas, as may be required by the provisions of this Chapter, in accordance with the approved Landscape Plan, Landscape Maintenance Plan and Landscape Maintenance Calendar for as long as the use/development for which the landscape plan was approved is in existence. (Ord. 2770, 4-3-13)
      b.   Landscaping Materials
         All landscaping materials, including mulch, shall be maintained in good condition and shall be replaced when necessary so as to present a healthy, neat and orderly appearance, and shall be kept free of refuse and debris.
      c.   Fences and Walls
         Fences, walls and other barriers shall be maintained in good repair.
      d.   Planting Beds
         Planting beds should be mulched with shredded bark, wood chips, or other similar materials.
      e.   Top Soil
         A cover of at least 6 (six) inches of topsoil shall be provided in turfed areas. A cover of at least 9 (nine) inches of topsoil shall be provided in all planting beds.
4. RESTRICTED PLANTING MATERIALS
(Ord. 2346, 12-15-06)
The following plant species shall not be used to satisfy minimum planting requirements of Chapter 11, Landscaping and Screening:
   a.   Ash tree
   b.   Scots (Scotch) pine
   c.   Austrian pine
1. SCALE AND NATURE OF LANDSCAPE MATERIAL
The scale and nature of landscape material should be appropriate to the site and structures. Large scale buildings, for example, should generally be complemented by larger scale plants.
2. SELECTION OF PLANT MATERIAL
Plant material should be selected for its form, texture, color, concern for its ultimate growth, durability, maintenance requirements and contribution to local ecosystem. See the Arboricultural and Open Space Manual for lists of plant materials recommended and not acceptable for planting. The use of native and adapted to northern Illinois plants is encouraged.
Native (or indigenous) plants have been described as having "evolved and adapted to local conditions over thousands of years." In North America, the term often refers to plants growing in a region prior to the time of settlement by people of European descent.
Adapted (or introduced) plants have been described as those that "reliably grow well in a given habitat with minimal winter protection, pest control, fertilization, or irrigation once their root systems are established."
Native and adapted plants are low maintenance plants. Since they have adapted to the regional climate without benefit of irrigation or chemical fertilizers, they require less water and no chemicals and, as a result, cost less to maintain. They also cost less to maintain because they have developed a resistance to most pests and diseases and generally do not require the application of pesticides. The cost of labor to control weeds is also reduced. Unlike many landscape plants that are selected almost exclusively for their aesthetic appeal, native plants are not only attractive, but also enrich the local ecosystem by providing food and shelter to many birds, butterflies and other animals. (Ord. 2770, 4-3-13)
3. SOFTENING OF APPEARANCE OF WALLS AND FENCES
Groupings of plant materials should be placed intermittently against long expanses of building walls, fences and other barriers to create a softening effect.
4. ENERGY CONSERVATION
In order to help conserve energy, the following landscaping measures are encouraged, where feasible:
   a.   Deciduous trees, shrubs, and vines should be placed on the south and west sides of buildings and plaza areas to provide shade from the summer sun.
   b.   Evergreens and other plant materials should be concentrated on the north side of buildings to dissipate the effect of winter winds.
5. BERMING
Earthen berms and existing topography should, wherever practical, be incorporated into the landscape treatment of a site. Slopes should be no greater than 1 (vertical) in 3 (horizontal) gradient.
1. APPLICABILITY
Where a parcel abuts a dedicated public right-of-way, landscaping shall be provided in accordance with the provisions of this Section.
2. TURF
The unpaved portion of a public right-of-way abutting a parcel shall be fine-graded and sodded. In instances where any of the following conditions are present, the Community development Director or his/her designated representative may approve the use of hydro seeding or a seed and blanket combination in lieu of sod: (Ord. 2770, 4-3-13)
   a.   No foot traffic expected
   b.   Limited access to source of water for regular application
   c.   Steeply sloped area
3. STREET TREES
Street trees shall be planted on private property unless the property owner, development Homeowners' Association, or developer of a subdivision executes a "Landscaping License Agreement' substantially in the form of the agreement provided in Appendix A of the Arboricultural and Open Space Manual and said agreement is approved by the Warrenville City Council in which case parkway trees may be planted in the parkway of streets under City of Warrenville jurisdiction.
   a.   Selection
      See the Arboricultural and Open Space Manual for acceptable and unacceptable tree species for right-of-way planting, species diversity requirements, and nursery stock size and grade requirements.
   b.   Number of Trees Required
      (i.)   The minimum number of street trees required shall be either one tree for every 40 (forty) linear feet of parcel-to-right-of-way boundary, or one tree per 800 (eight hundred) square feet of parkway area, whichever is larger.
      (ii.)   When the parcel is subdivided into lots, at least I (one) street tree for each lot shall be provided.
   c.   Location and Spacing
      Street tree plantings that are not evenly spaced may be grouped, with a minimum spacing of at least 15 feet between trees. See the Arboricultural and Open Space Manual for additional street (parkway) tree location and spacing requirements.
4. OTHER RIGHT-OF-WAY PLANTINGS
With the execution and approval of a Landscaping License Agreement substantially in the form of Appendix A, shrubs and perennial plants and grasses, especially native prairie or savannah plantings, may be used in addition to street trees. See the Arboricultural and Open Space Manual for additional right-of-way planting size and location requirements.
1. APPLICABILITY
All developments with 10 (ten) or more parking spaces shall provide Perimeter Parking Lot Landscaping in accordance with the provisions of this Section. All developments with 20 (twenty) or more parking spaces shall provide Interior Parking Lot Landscaping in accordance with the provisions of this Section.
2. INTERIOR PARKING LOT LANDSCAPING

Such alternative interior parking lot landscaping shall be authorized by the City through either the preliminary and/or final PUD Plan review and approval process and shall not trigger the need for a public hearing or the approval of a Site Specific Amendment or Site Specific exception.
      (iv.)   Visibility - Visual sight lines at intersections, including intersections within the parking area, shall not be impeded by landscaping material. (Ord. 2770, 4-3-13)
   c.   Landscaping Material
      (i.)   Type - The primary landscaping materials used in parking lots shall be trees which provide shade or are capable of providing shade. Ornamental trees, shrubbery, hedges, and other live planting materials may be used to supplement the tree landscaping, but shall not be the sole contribution to the landscaping. No gravel, concrete, or other artificial surface cover is allowed in interior planting islands, except as paving for pedestrian pathways.
      (ii.)   Quantity - Trees shall be planted with a spacing of not less than 75 (seventy-five) feet and so that at least one tree is located in the area occupied by each 20 (twenty) parking spaces.
