The purpose of this section is to establish standards for required landscaping for development. (Ord. 2013-20)

The following general standards apply to all land within the city of Carbondale's zoning jurisdiction. (Ord. 2013-20)

All landscaping shall meet the following minimum requirements:

   A.   Landscape Requirements And Maintenance:

      1.   All required front yards that are not covered by an approved impervious surface shall be seeded and/or sodded with grass or otherwise landscaped. Landscaped beds shall be defined using mulch or decorative rock and shall be well kept and maintained free of weeds and other deleterious growth.

      2.   Any dead tree located on private property shall be completely removed, including the stump and any exposed roots. The city may require the replacement of the tree if it is required as part of a site plan development.

      3.   These provisions do not apply to land zoned F, AG, or RR.

   4.   For specific guidance surrounding pollinator-supportive landscaping, see Chapter 11-6.

(Ord. 2013-20; Ord. 2023-19)

   A.   Landscaping Plan: All commercial and residential developments except one single-unit dwelling or one two-unit dwelling shall be required to submit a landscape plan meeting all of the requirements of this chapter. The landscape plan shall be reviewed for compliance and approved by the planning services division.

   B.   Design Standards:

      1.   Landscaped areas shall be provided totaling a minimum of ten percent (10%) of the total paved parking area. All landscaped areas shall be clearly defined by decorative rock and/or mulch and contain plantings proportional to the square footage of the landscaped area. All landscaped areas shall be properly maintained and kept free of weeds and other invasive species.

         a.   In areas where the amount of landscaping required exceeds two thousand five hundred (2,500) square feet, the applicant may exchange the amount of required landscaping over two thousand five hundred (2,500) square feet at a rate of six hundred (600) square feet for one shade tree. The development services director or designee shall determine the location of the shade trees and the approval and location shall be given in writing, with complete documentation of the requirements.

      2.   Landscaped islands shall be included at the end of each row of parking stalls that abuts an internal traffic aisle.

         a.   Landscaped islands at the end of a row of parking stalls containing a single parking module shall provide at a minimum a ninety (90) square foot landscaped island.

         b.   Landscaped islands at the end of a row of parking stalls containing a double parking module shall provide at a minimum a one hundred eighty (180) square foot landscaped island. (Ord. 2013-20)

      3.   All parking lots shall include new trees in accordance with the following schedule:

 

(Ord. 2013-31)

      4.   In parking lots with more than twenty (20) spaces, thirty percent (30%) of required trees shall be placed within the perimeter of the actual paved parking lot surface area.

      5.   In no case shall ornamental trees account for more than fifty percent (50%) of the total required trees planted.

      6.   Trees shall be protected from potential damage by vehicles with curbs or other approved barriers.

      7.   Where parking lots are adjacent to a public right of way on an arterial or collector street, a minimum seven foot (7') buffer shall be provided between the parking lot and the right of way line. This buffer shall be seeded or sodded and include at least one tree every fifteen feet (15'). Where the code requires a larger buffer between the parking lot and the right of way line, the larger buffer shall be provided.

      8.   All other parking lots, not located on an arterial or collector street, shall provide a minimum three foot (3') buffer between the parking lot and the right of way line. This buffer shall be seeded or sodded.

      9.   Flexibility in placement of treed landscape islands may be allowed for creative parking lot design and preservation of existing trees and vegetation. However, no more than twenty (20) parking spaces not separated by a treed landscape island shall be allowed. Islands shall always be required at each end of a row of parking spaces.

      10.   Up to forty (40) contiguous parking spaces may be allowed where rows of head to head parking spaces are separated by a six foot (6') wide linear treed landscape island.

      11.   Parking lots shall be designed to avoid creating large open expanses of paving. All parking lots shall include landscaping in accordance with the standards established by this section. Existing trees shall be preserved where possible. Surfaces denuded of vegetation shall be seeded or sodded to prevent soil erosion.

   C.   Primary Materials: Trees, low shrubs, and ground cover shall be used as the primary landscape materials. Ornamental, medium sized, and shade trees shall be incorporated into the design. Tall shrubs or low branching trees that may restrict the visibility of motorists or pedestrians should be avoided. (Ord. 2013-20)

      1.   The following table includes a list of approved tree species. If a request is made to plant a species not included on the list, it must first be approved in writing by the city's forestry division.

      ORNAMENTAL TREES

      (15 - 30+ Feet In Height At Maturity)

 

      SHADE TREES

      (35 - 80+ Feet In Height At Maturity)

 

Certain species may not be recommended from time to time due to current biological threats or other recognized industry practices.

(Ord. 2016-72)

      2.   Wherever practicable, new landscaping shall use native materials, as specified by the University Of Illinois Extension Service in its "Illinois Plant, Landscape And Nursery Technology" publications and website.

      3.   Preservation and protection of existing native species of plant material is strongly encouraged. Existing native species and natural cover should be retained wherever possible. Where planting requirements for landscaped areas result in the need for additional trees or shrubs in an existing natural area, there shall be minimum disturbance to native species.

      4.   Where it is not possible to retain existing natural ground cover, landscaped areas shall be seeded and/or sodded, or provided with other acceptable ground cover.

      5.   Landscaping should be used to minimize potential erosion through the use of plant materials, which aid in soil stabilization.

      6.   Landscaping should maximize shading of streets and off street parking areas.

   D.   Standards For Plant Materials: When the seasonal nursery stock does not provide for the required plant and tree sizes, the development assistance committee may approve alternative sizes of the required plantings. All vegetation to be planted shall meet the following standards:

      1.   Nursery stock shall meet with minimum requirements of the "American Standards For Nursery Stock" (ASNS), published by the American Association Of Nurserymen, Inc.

      2.   Plants shall be sound, healthy, vigorous, free from mutilation, plant diseases, insect pests or their eggs, and fungus and shall have healthy, normal root systems. Plants shall be nursery grown stock in containers or freshly dug, balled, and burlapped.

      3.   Caliper measurement, height measurement, minimum container volume, drown spread, and number of canes shall conform to the requirements of the "American Standards For Nursery Stock" (ASNS), published by the American Association Of Nurserymen, Inc.

      4.   Shade trees shall be at least two inches (2") in diameter at a point three feet (3') above the ground when planted. Ornamental trees shall be a minimum one inch (1") in diameter at a point three feet (3') above the ground when planted. Trees shall not be planted any closer than two and one-half feet (2.5') from the edge of any landscaped area within and along the edges of parking areas and ingress/egress points.

      5.   Shrubs shall be a minimum of twelve inches (12") to eighteen inches (18") high and/or eighteen inches (18") spread for internal landscaped areas of parking areas and a minimum of twenty four inches (24") to thirty inches (30") height for landscaped strips lying between parking areas. Shrubs making up buffer types "A" and "B" where a continuous hedge is required shall be a minimum of thirty six inches (36") high, otherwise, a minimum size of twenty four inches (24") to thirty inches (30") height is allowable. Shrubs making up buffer types "C" shall be a minimum of thirty six inches (36") high with an aggregate average height of forty eight inches (48").

      6.   Ground covers other than grass shall be planted in such a manner as to provide reasonably complete coverage within one year after planting.

      7.   Turf establishment areas may be seeded, sodded, plugged, or sprigged except that sod and/or ground cover plants are required for slopes greater than four to one (4:1) (25 percent).

      8.   Landscaping materials shall meet the requirements of the corner site visibility standards in section 15.4.6 of this chapter.

   E.   Design For Safety: To ensure both the perceived and actual safety of pedestrians and bicyclists, it is important to provide clear visibility of the immediate environment along sidewalks and trails. Buffers and other landscaped areas adjacent to sidewalks, trails or other pedestrianways required for pedestrian circulation shall be subject to the standards in this subsection; these standards shall not apply to landscaped areas adjacent to recreational trails:

      1.   Such areas shall include low growing shrubs (less than 3 feet in mature height) and flowers and grasses within twenty feet (20') of the nearest edge of the sidewalk or trail;

      2.   Such areas shall not include berms within fifty feet (50') of the nearest edge of the sidewalk or trail;

      3.   Such areas may include fences or walls, subject to the following additional standards:

         a.   Fences or walls that are no taller than three feet (3') shall be allowed within a buffer area adjacent to sidewalks or trails;

         b.   Fences, such as split rail fences, that do not impair visibility, shall be allowed;

         c.   All other fences or walls are prohibited in portions of open space areas within fifty feet (50') of a sidewalk or trail subject to this subsection.

      4.   Where berms are used within a landscaped area, slopes shall not exceed forty five degrees (45°) and shall be completely covered with vegetation. (Ord. 2013-20)

   A.   Maintenance of all required landscaped and buffer areas shall be the responsibility of the property owner. Failure to maintain plantings and other features of a required landscaped area in an attractive and healthy state shall be considered a violation of this zoning ordinance. Remedies shall include, but not be limited to, revocation of a certificate of compliance and the related certificate of occupancy.

The planning services division shall periodically conduct the inspection of all landscaping planted as a site plan requirement to ascertain whether or not the landscaping is still alive. In the event that landscaping has died or been removed, the city shall require their replacement. If compliance is not received within three (3) months of written notice to the property owner, appropriate steps shall be taken to secure compliance. (Ord. 2013-20)

   A.   Determination Of Buffer Requirements: Buffers shall be required for all new development and redevelopment except as provided in subsections A5 and A6 of this section. The table of buffer requirements (see table in subsection C2 of this section) describes the type of buffer required as determined by the type of proposed use and the type of use which is designated, approved, or existing on lands adjacent to the proposed project. In order to determine the type of buffer required, the following procedures shall be followed:

      1.   Identify the type of use for the proposed project.

      2.   On sites with extensive tree cover or large tracts of land, an aerial photograph depicting impacted/nonimpacted areas may be submitted with a survey of a representative area no less than one-half (0.5) acre in size.

      3.   Where an abutting property has a lawful nonconforming use of less intensity than the allowable use of the property, buffering shall be based upon the allowable use.

      4.   Refer to the table of buffer requirements in subsection C2 of this section, for buffer requirements on each property boundary or portion thereof and select the required buffer option for the specified type of buffer from those outlined in subsection B of this section.

      5.   The following developments are not required to provide buffers:

         a.   Construction of single-family homes or duplexes.

         b.   Passive agriculture activities such as livestock grazing, orchards, silviculture, or croplands.

         c.   Passive recreation such as golf courses, hiking/equestrian/bicycle trails, or boardwalks.

         d.   Conservation lands.

      6.   Buffers are also not required in the following circumstances:

         a.   When the property line abuts a railroad right of way.

         b.   Within fifteen feet (15') of the edge of a street surface or curb line to prevent obstructing visibility.

         c.   When the nonresidential use is compatible with a residential use, such as cropland, forests, parks, etc. (The parking lot or active recreational area of a park requires a buffer yard.)

         d.   When the use of a property changes from one nonresidential or high density residential use to another nonresidential or high density residential use and the new use is not expanded in the direction of or parallel to a residential use and when the new use does not result in an increase in noise or light reaching a residential use that would otherwise be required to be protected by a buffer yard.

         e.   When natural features of the property provide the required screening and buffer yard.

         f.   Existing legal nonresidential uses or proposed uses that have an approved site plan on file on the effective date hereof, unless expansion beyond that approved as of the effective date hereof occurs in the direction of or parallel to a residential use.

      7.   When it is determined to be in the public interest, the buffer yard requirement may be waived by the city council when a senior citizen housing conversion development is established as a special use in an R-1 zone.

   B.   Types Of Buffers: Required buffer types shall consist of A, B, and C. Trees in buffers of ten feet (10') or less should be understory trees. Trees in buffers of more than ten feet (10') may be canopy or understory trees provided however, at least one- half (1/2) of the required trees shall be canopy trees.

      1.   Landscape Credits: Landscape credits for buffers shall be determined from the following table:

      LANDSCAPE CREDIT UNIT (LCU) VALUES

 

 

      2.   Type A Buffer: A type A buffer shall be at least ten feet (10') in width and shall have plant materials equal to twenty (20) landscape credits per one hundred feet (100') with a visual screen four feet (4') high consisting of evergreen plantings, fences, walls or a combination thereof.

      3.   Type B Buffer: A type B buffer shall be at least fifteen feet (15') in width and shall have plant materials equal to thirty (30) landscape credits per one hundred feet (100') with a visual screen five feet (5') high consisting of evergreen plantings, fences, walls or a combination thereof.

      4.   Type C Buffer: A type C buffer shall be at least twenty feet (20') in width and shall have plant materials equal to forty (40) landscape credits per one hundred feet (100') with a visual screen six feet (6') high consisting of evergreen plantings, fences, walls or a combination thereof.

      5.   Buffers Along Sidewalks: Where a public street separates a land use required to install a buffer from the protected land use and where the land use required to install the buffer will include a parking lot adjoining that street, the required buffer shall be broken into two (2) parts:

         a.   A buffer five feet (5') wide shall be established between the parking area and the public street or sidewalk; such buffer shall have plant materials with ten (10) landscape credits per one hundred feet (100') and a visual screen no more than thirty inches (30") high;

         b.   An additional buffer meeting the standards required by this section less five feet (5') in width and ten (10) landscape credits per one hundred feet (100') shall be installed on the other side of the parking lot, providing visual separation between the use required to include the buffer and the protected use, with the parking lot and the smaller buffer in between.

   C.   Required Buffers:

      1.   Purpose/Principles: The intent of this subsection is to require a more intensive use to provide a landscaped buffer to provide visual screening, separation and some sound buffering between it and a nearby protected use. (Ord. 2013-20)

      2.   Buffer Table: Any use falling in a zoning district listed across the top of the following table shall be required to install a buffer as designated by the letters A, B or C to separate it from any use or land located in a zoning district listed down the left side of the table; if the cell reflecting the intersection between two (2) districts is blank, no buffer between them is required.

   City of Carbondale   REQUIRED BUFFERS

 

(Ord. 2013-31)

      3.   Exceptions: Where a use that would be required by this section to provide a buffer is separated from the use that would be protected by any of the following, no buffer is required:

         a.   A railroad track in active use;

         b.   A state highway; or

         c.   A public street with at least fifty feet (50') of right of way.

   D.   Modifications To Buffer Requirements:

      1.   A proposed development may be allowed a fifty percent (50%) reduction in the required buffer width in no case to allow a required buffer to be less than five feet (5') in width providing one of the following conditions exists and is indicated on the plan for the proposed development or project:

         a.   The adjacent property is designated with a nonresidential land use district and is vacant;

         b.   The adjacent property has an existing required landscaped buffer; or

         c.   The adjacent property has existing vegetation sufficient in size, types of plantings, and location that serve in the same capacity as a required buffer.

      2.   For projects that propose to retain an undisturbed open space area between the extent of the development and the property line, if the director of development services finds that such area will substantially serve the purpose of a buffer, the director of development services may give credit to the owner or owner's designee for part or all of the undisturbed open space toward the buffer requirements of this section. This exemption does not apply to industrial, extractive, or outdoor recreation uses. Additionally, the plan must show the undisturbed area has an existing mixture of grass, trees, and shrubs, and other vegetation that would serve in the same capacity as the required buffer.

      3.   For projects that are required to provide a buffer to adjacent residentially designated property that is currently vacant, the owner or owner's designee may plant the required buffer at the proper density and configuration. All plants utilized shall be of a type that the growth will reach the required height criteria within a three (3) year period from the time of planting.

      4.   Alternative designs for required buffers may be approved by the director of development services upon a finding that the required buffer will require alterations of the existing improvements on the property.

   E.   Use And Location Of Buffers:

      1.   Allowed Uses: Areas set aside as required buffers may also be used as follows:

         a.   Satisfaction of minimum setback requirements, if any.

         b.   Satisfaction of minimum open space requirements, if any.

         c.   May contain stormwater retention or detention areas, so long as the required buffer plantings are provided and the design and landscaping of the buffer does not interfere with proper functioning of the drainage system and the design water depth does not harm the viability of the plantings.

         d.   Passive recreation such as pedestrian, bicycle, or equestrian trails subject to the following limitations:

            (1)   No plant material is eliminated.

            (2)   There is a minimum width of ten feet (10') of pervious material at all points in the buffer, after subtracting any part of a trail covered with impervious material.

            (3)   The total width of the buffer is maintained.

            (4)   All other requirements of this zoning ordinance are met.

         e.   Installation of underground utilities, so long as the location and use of the utility lines does not interfere with required buffer plantings.

      2.   Prohibited Uses: The following uses shall not be allowed in a required buffer: principal structures, accessory structures, play fields, stables, swimming pools, tennis courts, or similar active recreation uses; storage facilities, or parking facilities.

      3.   Location And Design:

         a.   Buffers shall be located on the outer perimeter of a lot or parcel, extending the entire length of the lot or parcel boundary line.

         b.   Buffers shall not be located on any portion of an existing, dedicated, proposed right of way, road easement, or private street.

         c.   Where an existing utility easement is partially or wholly within a required buffer, the developer shall design the buffer to eliminate or minimize plantings within the easement. Such design may require a buffer with more land area (see subsection B of this section).

         d.   Where a proposed development is a mixed use project, buffers shall not be required between various constituent parts except that any nonresidential use shall be separated from the residential use by internal landscaping. (Note: It is the intent to allow flexibility of design within the confines of a mixed use development, but to nevertheless require landscaping for the residential portion of the project from potential negative impact of a proposed nonresidential portion of the project.)

         e.   All general landscape requirements of section 15.4.1.3 of this chapter shall be met.

   F.   Fencing Within Buffers: Fencing for the purpose of security or protection is allowable within all buffers provided the fence is in compliance with applicable standards of section 15.4.2 of this chapter. Developments proposing a privacy fence five feet (5') or more in height within a required buffer, may be allowed a fifty percent (50%) reduction in the density of plantings required. Such request shall be submitted in writing by the owner or owner's agent and shall include provisions by the owner for maintenance of the buffer and the fencing. This reduction does not apply to industrial, extractive, or active outdoor recreational uses. (Ord. 2013-20)

These standards shall apply to all land within the city of Carbondale's zoning jurisdiction. Fences, walls and hedges other than those required under section 15.4.1.6 of this chapter are allowed in required yards and are not subject to setback requirements that apply to other structures but are subject to the following standards:

   A.   General Height Limit: Unless expressly required by another provision of this title, no fence, wall or hedge shall exceed eight feet (8') in height.

   B.   Height Limit In Relation To Adjacent Structures: Any segment of a wall, screen, hedge or fence (other than a chainlink or equally open fence without slats) located closer than eight feet (8') to a window in a residential structure on an adjoining lot shall not exceed the following height restrictions:

      MAXIMUM WALL, SCREEN, HEDGE OR FENCE HEIGHT

 

Note: The proposed distance and corresponding maximum height may be interpolated to the next nearest inch. In no case shall the height of any wall, screen, hedge or fence exceed 8 feet in height or be required to be less than 3 feet 6 inches in height.

   C.   Accessibility To Utilities: No wall, screen, hedge, or fence shall be located or constructed in a manner that denies access to an existing utility meter or emergency shutoff for a structure on an adjacent lot. If sufficient space between the wall, screen, hedge or fence and the existing structure is not provided for such access, then access may be provided by placing in the wall, screen, hedge or fence, a gate, door, or other opening of sufficient size to allow for access to the meter or emergency shutoff.

   D.   Safety Considerations: Where allowed by this section, a fence or wall that is seven feet (7') or more in height shall be allowed only if it has no gates, openings or other breaks in any section of the fence or wall that is within fifty feet (50') of the nearest edge of the sidewalk or trail. (Ord. 2013-20)

These standards shall apply to all land within the city of Carbondale's zoning jurisdiction.

   A.   Intent: It is the intent of this subsection to allow the construction of fences and walls from any materials designed or manufactured for that purpose while preventing the use of materials designed for other purposes for fences. This section shall be broadly construed to fulfill that purpose. The determination of the planning services division of whether a fence conforms to the intent of this section shall be determinative but is appealable to the board of zoning appeals.

   B.   Approved Materials: Materials approved for fencing under this section include, but are not necessarily limited to:

      1.   Chainlink;

      2.   Wire mesh;

      3.   Barbed wire (in AG, RR, F, and PAD districts only or as necessary for security for the following types of nonresidential uses: electrical substations, auto storage yards, construction material storage yards, etc.);

      4.   Split rail;

      5.   Pickets;

      6.   Any type of cedar fencing material;

      7.   Plastics and other synthetic materials designed to resemble traditional fencing material;

      8.   Brick;

      9.   Concrete block;

      10.   Adobe or other pressed brick;

      11.   Any building material used lawfully as exterior material for the principal building located on the site with the fence; or

      12.   Rough cut or natural wood.

   C.   Prohibited Materials: The following materials are expressly prohibited from use as fencing in the city; this list is representative and not fully inclusive:

      1.   Wooden pallets;

      2.   Trash or other barrels;

      3.   Vehicles or vehicle parts;

      4.   Railroad ties (may be used as posts);

      5.   Railroad cars; and

      6.   Roofing material, including corrugated steel. (Ord. 2013-20)

The following standards apply to all property within the city of Carbondale's zoning jurisdiction. For parking lot lighting standards see subsection 15.4.8.6K of this chapter. (Ord. 2013-20)

Where lighting facilities are provided, they shall be designed to provide safe, convenient and efficient lighting for pedestrians and vehicles. Lighting shall be designed in a consistent and coordinated manner for the entire site and shall be designed to meet the following standards:

   A.   Exterior light sources such as luminaires or lampposts shall not exceed the following heights:

      1.   Within a parking lot that is not located in or within one hundred feet (100') of any R-1 or R-2 zoning district, thirty feet (30');

      2.   Within a parking lot that is located in or within one hundred feet (100') of any R-1 or R-2 zoning district, fifteen feet (15'); or

      3.   Within any nonvehicular pedestrian areas, fifteen feet (15').

      4.   No luminaire or lamppost shall exceed thirty feet (30') in height except those provided in an LI, GI, PAD, or SIU district or those illuminating recreational sports fields or arenas during hours of use.

   B.   All new and replacement outdoor lighting fixtures shall employ one or more of the following techniques to reduce glare or spillage: full cutoff fixtures; fully shielded fixtures, or "NEMA" type II, III and IV reflectors and shall be maintained in such a manner as to confine light rays to the premises. All lighting, regardless of location, shall be designed to prevent direct glare, light spillage, and hazardous interference with residential property or automotive, bicycle and pedestrian traffic on adjacent streets and properties. (Ord. 2013-20)

When a parking lot adjoins or is within three hundred feet (300') of a residential area, provision shall be made to screen all vehicle lights to curtail direct illumination of the residential area; screening provided on the land may be provided by the use of closely spaced evergreen trees or physical structures which will harmonize with the developed use of the land and with the residential area. Vehicle light need not be screened on that portion of a site bounded by and parallel to a street. (Ord. 2013-20)

   A.   New subdivisions or resubdivisions shall provide stormwater detention as detailed in section 15.8.6.8 of this title.

   B.   The standards in this section shall apply to any development for which a site plan must be submitted in the following cases:

      1.   Any development greater than two (2) acres.

      2.   Any development less than two (2) acres in which there is an expected increase in stormwater runoff when comparing the predevelopment and postdevelopment stormwater drainage calculations. The predevelopment site shall be considered those conditions which existed a maximum of twelve (12) months prior to the site plan being submitted. Detention shall be provided to accommodate the expected increase in stormwater runoff for the site.

   C.   The standards of this section shall not apply to any development located within the BPR, primary business, district. (Ord. 2015-04)

   A.   All drainage designs, storm sewers, detention/retention basins, and other such stormwater runoff appurtenances shall be laid out and designed by an Illinois licensed professional engineer in accordance with the requirements set forth herein and standard engineering practices.

   B.   Surface water runoff from parking lots, driveways, roofs and pavements shall not be allowed to cross sidewalks or be directed onto private property that is not a part of the site unless easements have been obtained to permit such off site drainage.

   C.   Surface water runoff shall be directed into municipal stormwater/drainage facilities, if available.

   D.   Stormwater runoff shall not be directed to nor connected to the sanitary sewer system. Any existing connections of stormwater runoff systems (i.e., storm sewers, downspouts, roof drains, etc.) to the sanitary sewer system shall be immediately removed or the persons in control of said connections shall be subject to citation.

   E.   Retaining walls shall be constructed where necessary for land stabilization. (Ord. 2013-20)

   A.   Referenced Standards: Specific technical aspects of all storm sewers shall be designed in accordance with this code, and in accordance with, but not limited to, the latest editions of following design standards:

   A.   General Information:

      1.   The purpose of this section is to explain the city's policy regarding the ownership, design, construction, and maintenance responsibility for detention basins. Detention basins are used to collect and hold stormwater runoff for a period of time to compensate for increases in stormwater runoff caused by reduced ground surface perviousness due to activities such as paving or building construction.

   B.   Design:

      1.   General:

         a.   Use section 15.4.4.4, "Hydrologic Design Standards", of this chapter, to determine design storm and hydrologic method of determining peak inflows - 10-year design storm of most critical duration (minimum 60 minute storm) as determined by the city engineer.

         b.   Detention basin sizing shall follow the methodology in "IDOT Drainage Manual", Pond Pack™ software, Hydroflow Hydrographs™ software, or AutoCAD Civil 3D™ software.

         c.   Outflow shall be limited to the calculated rate of runoff for the sites existing topography as if it was entirely covered with grass; assuming normal soil conditions, reasonable grass coverage, and normal ground saturations for a 5-year design storm of the most critical duration (minimum 60 minute storm) as determined by the city engineer.

         d.   Parking lot and other such surfaces shall not be permitted to be used for stormwater detention.

         e.   Plans shall clearly indicate normal and high water elevations, design storage volume, minimum, maximum and typical slopes.

         f.   Detention basins shall release the 10-year storage volume within twenty four (24) to forty eight (48) hours after the end of the rainfall event.

         g.   Emergency overflow routes shall be clearly designated for runoff in excess of the 10-year storm.

         h.   Minimum outlet storm sewer size shall be twelve inches (12"); smaller diameter restrictions (e.g., orifice plate or short pipe length) are acceptable.

         i.   Inlet and outlet pipes shall be provided with concrete end sections and erosion protection.

         j.   Detention ponds and their appurtenances (i.e., storm sewer systems, weirs, dams, orifices, and specialized outflows) shall be designed by a professional engineer registered in the state of Illinois.

         k.   "Bubble up" outlets are prohibited.

         l.   Pumped outlets and other active control structures are discouraged and must be preapproved on a case by case basis by the city engineer.

         m.   Temporary erosion techniques shall be used as required to ensure a full stand of cover vegetation in minimum time.

         n.   Detention basin side slopes above normal pool shall be designed with permanent erosion protection consisting of grass, nongrass vegetation, or other permanent finish. Permanent erosion protection shall be aesthetically suitable to the development or existing surrounding land use.

      2.   Dry Bottom Basins:

         a.   Side slopes shall be a maximum of 4H:1V. If retaining walls are used, their height is limited to four feet (4'). Retaining wall design and material type shall be approved by the city engineer.

         b.   Dry bottom basins shall have one percent (1%) minimum bottom slopes or underdrain systems as approved by the city engineer.

         c.   Dry bottom basins shall include a low flow channel with some form of erosion protection, for example a concrete "V" gutter.

      3.   Wet Bottom Basins:

         a.   Above water side slopes shall be a maximum of 4H:1V. If retaining walls are used, their height is limited to four feet (4'). Retaining wall design and material type shall be approved by the city engineer.

         b.   In accordance with IDOT standard specifications section 204, below water slopes shall be a maximum of 4H:1V except that slopes of 2H:1V will be permitted below a point where the proposed water depth will be eight feet (8') or greater.

         c.   Wet bottom basins shall have a natural or artificial means of aeration.

         d.   If fish or other aquatic wildlife are desired, a minimum depth of eight feet (8') shall be maintained over at least twenty five percent (25%) of the pond's surface area.

         e.   So called "safety shelves" are not required as they promote the growth of algae and may cause entrapment.

         f.   To minimize erosion caused by wave action, shoreline stabilization shall be required around all wet bottom detention basins. Shoreline stabilization shall extend down the side slope to an elevation one foot (1') below the normal water surface elevation and up the side slope to an elevation one foot (1') above the normal water surface elevation. Approved shoreline stabilization methods include riprap revetment constructed in accordance with the requirements of the Illinois department of transportation "Standard Specifications For Road And Bridge Construction", latest edition; cast in place portland cement concrete retaining walls; or modular concrete block retaining walls. Alternative shoreline stabilization methods may be submitted to the city engineer for review and approval. Any proposed shoreline stabilization method shall be reviewed and approved by the city engineer prior to installation.

         g.   An outlet structure shall be provided to allow dewatering of the pond for maintenance. Gravity dewatering is strongly preferred.

         h.   Wet bottom basin design shall include an evaluation of soil permeability. A basin liner shall be included in the design if needed to ensure water retention to normal pool elevation.

      4.   Underground Detention Systems:

         a.   Underground systems may be permitted subject to the approval of the city engineer.

         b.   All underground systems shall be designed so that inspection and cleaning of these systems is easily accomplished.
