§ 154.232 SCREENING.
   (A)   Landscape screening must be provided in accordance with all applicable county ordinances.
   (B)   In cases where lots have frontage along both an interior street and another street (double-frontage) or abut a nonresidential use or zoning classification, a landscaped earthen berm or fence must be constructed to the following standards.
      (1)   Landscaping berms must be constructed with slopes not to exceed a three to one gradient, with side slopes designed and planted to prevent erosion and with a rounded surface a minimum of three feet in height and five feet in width at the highest point of the berm, extending the length of the berm. Berm slopes must be protected with sod, seed, shrubs or other form of natural ground cover.
 
      (2)   A detailed landscape/berm plan must be submitted to show that adequate vegetative plantings have been provided to create a screen.
      (3)   No screening may interfere with drainage patterns or intersection visibility requirements. See § 154.125(C).
(Ord. passed 7-8-1970; Res. 09-167, passed 6-18-2009)
§ 154.233 LANDSCAPE MATERIAL.
   (A)   A list of desirable tree and shrub species is contained in the Will County Developers’ Handbook.

§ 154.234 LANDSCAPE PLACEMENT.
   (A)   All plant material must be planted in a manner that does not interfere with drainage patterns, overhead wires, utilities, street or sidewalk pavement.
   (B)   No trees or other landscaping may be located closer than ten feet to a fire hydrant or other above-ground utilities.
   (C)   No landscaping may interfere with intersection visibility requirements. See § 154.125(C).
(Ord. passed 7-8-1970; Res. 09-167, passed 6-18-2009)
§ 154.235 INSTALLATION STANDARDS.
   (A)   Plant material must comply with the American Standards for Nursery Stock, published by the American Association of Nurserymen.
   (B)   All trees must be grown in a nursery located in the northern half of the state and licensed by the state.
   (C)   All plant material must be installed free of disease and in a manner that ensures the availability of sufficient soil and water to sustain healthy growth.
   (D)   All tags, wires, plastic ties and rope must be cut from each tree to prevent girdling the tree. The burlap must be pulled back from the upper third of the root ball. If a plastic “burlap” is used, it must be removed from the root ball in its entirety.
   (E)   When planting, the hole must be dug approximately three times wider than the roots or root ball.
   (F)   All plant material must be planted with a minimum depth of three inches of mulched material and a diameter of three feet around the base of the tree.
 
   (G)   Trees must be staked with posts and not stakes in areas of high wind for one to three years to allow the growth of new roots to stabilize. All ropes must be covered to prevent cutting into bark.
   (H)   The planting season is approximately September 15 to December 15 and March 15 to June 15.
   (I)   Any excess soil, clay or construction debris must be removed from the planting site, before planting of individual trees at final grade.
   (J)   The county is authorized, at its sole discretion, to retain a professional landscape architect or arborist to review landscape plans. All expenses incurred by the county for the use of landscape architects or arborists must be reimbursed by the developer.

GENERAL PROVISIONS FOR CONSERVATION DESIGN OPTION
§ 154.250 PURPOSE/DESCRIPTION.
   (A)   A conservation design subdivision designed in accordance with this section and § 154.251 is a by-right permitted use option in the E-1, E-2, R-1, R-2, R-2A, R-3 and R-4 zoning districts. Other development options include a conventional residential subdivision or a planned unit development residential subdivision. When this option is utilized, the regulations of this section are intended to encourage subdivision designs that are more efficient and provide more open space and greater natural resource protection than conventional subdivision designs. One goal of conservation design subdivisions is to allow more compact and less costly networks of streets and utilities. They may also help preserve aquifer recharge, reduce stormwater runoff, reduce non-point source pollutant loading rates and preserve an area’s semi-rural character. Conservation design subdivisions are intended to encourage the provision of open space and recreational amenities for residents and preserve natural, environmentally sensitive and other resources.
   (B)   The conservation design subdivision standards of this section require that a specified portion of each development be set aside and permanently preserved as open space, which can be used to provide recreational opportunities for the subdivision’s residents and/or to conserve and protect significant natural resources, in accordance with the regulations of this chapter.
   (C)   Review period. No later than five years from the date of passage of the initial Conservation Design Ordinance, the County Board, or a committee, subcommittee or commission thereof, shall consider whether amendments are necessary to make this section, §§ 154.251, 154.265 through 154.269 and 154.280 through 154.286 consistent with recommendations of the Land Resource Management Plan, to encourage new or improved conservation design building practices which may have been developed and which may have application in the county, to correct deficiencies or difficulties which may have developed in administration of §§ 154.250, 154.251, 154.265 through 154.269 and 154.280 through 154.286, or for other reasons as the County Board may determine.

§ 154.251 GENERAL DESIGN PRINCIPLES.
   (A)   Conservation design subdivisions are subject to all other subdivision design and improvement standards of this chapter unless otherwise expressly stated.
   (B)   Lots and development sites within conservation design subdivisions must, to the maximum extent practical, be located outside of areas containing woodlands, grasslands, surface waters, steep slopes, drainageways, rock outcroppings and other natural resource features. See the figure below. A natural resources inventory report, that includes site specific data, prepared by the Will/South Cook Soil and Water Conservation District shall be submitted to aid in identifying areas that merit conservation.
 
   (C)   Impervious areas must be limited and, to the maximum extent practical, be sited and designed to minimize stormwater runoff impact to the watershed’s receiving waters by:
      (1)   Minimizing concentrated stormwater flow;
      (2)   Minimizing and breaking up or disconnecting large areas of impervious surface into smaller areas;
      (3)   Maximizing the use of sheet flow through vegetated areas;
      (4)   Maximizing the flow length through vegetated areas;
      (5)   Encouraging groundwater recharge; and
      (6)   Providing natural preserve areas where natural soils will remain undisturbed and soil compaction activities are prohibited.
   (D)   Stormwater best management practices (BMPs) shall be used to protect water quality, preserve natural hydrology and minimize overall impacts of development on aquatic resources. BMPs may include, but not be limited to, the following practices:
      (1)   Use of naturalized detention basins designed to maximize removal and transformation of run-on pollutants;
      (2)   Use of wet-bottom detention basins and native, emergent vegetation along their periphery and in bottoms of wetland basins;
      (3)   Use of stilling basins at major detention basin inlets and use of maximum distances between major inlets and outlets;
      (4)   Where detention basins discharge into adjacent or downstream wetlands, use of detention basins outlet structures designed to spread and infiltrate run-off through use of level spreader devices;
      (5)   Use of bio-swales in lieu of stormwater piping;
      (6)   Use of permeable pavers where practical; and
      (7)   Curb and gutter, pavement widths, right-of-way widths and sidewalk requirements will be waived or modified in a conservation design subdivision contingent upon the approval of the appropriate highway authority.
