17-7-0100 Overlay districts generally.
   17-7-0101 Described. Overlay districts deal with special situations or accomplish specific city goals that cannot be easily or efficiently addressed through the use of base districts. As the name implies, overlay districts "overlay" applicable base district classifications to alter some or all of the zoning regulations that apply to particular sites. Overlay districts are shown on the maps in the Official Zoning Atlas.
   17-7-0102 Effect. Overlay district regulations supplement the zoning regulations of the applicable base district. When overlay district standards conflict with applicable base district standards or other regulations of this Zoning Ordinance, the regulations of the overlay district always govern. When no special overlay district standards are specified, the base district standards and all other applicable regulations of this Zoning Ordinance will govern.

17-7-0400 North Branch Corridor Overlay District.
   17-7-0401 Purpose.
      17-7-0401-A The North Branch Corridor Overlay district (NBCO) regulations supplement the zoning regulations that apply under a property's base zoning district. The general purpose and intent of the NBCO is to help:

         2.   preserve and enhance open space and recreational opportunities along the North Branch of the Chicago River;
         3.   retain and modernize existing planned manufacturing district (PMD) zoning in some areas;
         4.   facilitate and guide land use transitions from the area's former PMD zoning in some areas; and
         5.   accommodate and promote compatible mixes of office, industrial, commercial and/or residential uses.
      17-7-0401-B When these overlay district regulations conflict with applicable base district or other regulations of this Zoning Ordinance, the regulations of the overlay district shall govern. When no overlay district regulations are specified, the base district regulations and all other applicable regulations of this Zoning Ordinance govern, unless otherwise more specifically regulated, including, without limitation, by a planned development.
   17-7-0402 Boundaries.
      17-7-0402-A The overlay district regulations of this Sec. 17-7-0400 apply to all property within an area generally bounded by West Webster Avenue on the north, North Kingsbury Street or the east bank of the North Branch Canal on the east, West Kinzie Street on the south and the Union Pacific Railroad on the west. The area is further divided into the following subdistricts:
         1.   NBCO-A, North subdistrict;
         2.   NBCO-B, Central subdistrict; and

Existing unenclosed uses may remain, subject to the screening requirements of Sec. 17-5-0600.
   17-7-0405 Rezonings. The rezoning provisions of this Sec. 17-7-0405 apply to all rezonings of property within the boundaries of the NBCO filed after the effective date of this Sec. 17-7-0400.
      17-7-0405-A NBCO-A Subdistrict.
         1.   Property in the NBCO-A subdistrict may not be rezoned to any zoning district classification other than B (Business), C (Commercial), POS (Parks and Open Space) or T (Transportation), provided that this provision is not intended to prohibit approval of planned development (PD) zoning for projects that meet the mandatory or elective PD thresholds of Sec. 17-8-0500 or 17-8-0600, respectively. Pursuant to Sec. 17-7-0406-A, rezoning to a zoning district classification that allows a base floor area ratio of more than 3.0 is prohibited.
         2.   All rezonings to a B or C zoning district within the NBCO-A subdistrict must be processed in accordance with the Type I zoning map amendment procedures of Sec. 17-13-0302 or the planned development procedures of Sec. 17-13-0600 (if the project qualifies as a mandatory or elective planned development pursuant to Sec. 17-8-0500 or Sec. 17-8-0600, respectively).
      17-7-0405-B NBCO-B Subdistrict. Property in the NBCO-B subdistrict may not be rezoned to any non-PMD zoning district classification, provided that this provision is not intended to prohibit approval of planned development (PD) zoning for projects that meet the mandatory or elective PD thresholds of Sec. 17-8-0500 or Sec. 17-8-0600, respectively.
      17-7-0405-C NBCO-C Subdistrict. Property in the NBCO-C subdistrict may not be rezoned to any zoning district classification other than DX (Downtown Mixed-Use), POS (Parks and Open Space) or T (Transportation), provided that this provision is not intended to prohibit approval of planned development (PD) zoning for projects that meet the mandatory or elective PD thresholds of Sec. 17-8-0500 or Sec. 17-8-0600, respectively. Pursuant to Sec. 17-7-0406-C, rezoning to a zoning district classification that allows a base floor area ratio of more than 5.0 is prohibited.
   17-7-0406 Floor Area Ratio.
      17-7-0406-A NBCO-A Subdistrict. All development in the NBCO-A subdistrict is subject to a maximum base floor area ratio of 3.0 or the floor area ratio of the underlying zoning district, whichever is less. Floor area bonuses may be authorized in accordance with Sec. 17-7-0407.
      17-7-0406-B NBCO-B Subdistrict. All development in the NBCO-B subdistrict is subject to a maximum floor area ratio of 3.0. No floor area bonuses are allowed in the NBCO-B subdistrict.
      17-7-0406-C NBCO-C Subdistrict. All development in the NBCO-C subdistrict is subject to a maximum base floor area ratio of 5.0 or the floor area ratio of the underlying zoning district, whichever is less. Floor area bonuses may be authorized in accordance with Sec. 17-4-1000.
   17-7-0407 Floor Area Bonuses in NBCO-A.
      17-7-0407-A Applicability. The floor area bonus provisions of this Sec. 17-7-0407 apply to floor area bonuses in the NBCO-A subdistrict.
      17-7-0407-B Eligibility. Only B- or C-zoned properties with a dash-3 bulk and density designation are eligible to receive floor area bonuses under this Sec. 17-7-0407.
      17-7-0407-C Purpose. The floor area bonus provisions of this section are intended to provide the opportunity for development projects in the NBCO-A subdistrict to achieve appropriate increases in floor area ratio above applicable base floor area ratios, while providing a corresponding economic incentive for developers to provide public amenities in the NBCO that improve the quality of life of city residents, employees, and visitors of the area and are a benefit to the public. This section shall be liberally construed and applied to achieve these stated purposes.
      17-7-0407-D Administration.
         1.   Planned Development Review. Floor area bonuses may be approved only in accordance with the planned development procedures of Sec. 17-13-0600. The zoning administrator must review proposed floor area bonus requests and make a recommendation to the Commissioner of Planning and Development and the Chicago Plan Commission. The Commissioner of Planning and Development and the Chicago Plan Commission shall each in turn make a recommendation to the city council. Floor area bonuses may be approved only if they are consistent with the purposes described in Sec. 17-1-0500, Sec. 17-4-1001, and Sec. 17-7-0407-C.
         2.   Submittal Requirements. All applicants for bonus floor area must file a bonus worksheet with the zoning administrator.
            (a)   The zoning administrator shall, by rule, establish a required form and content for such worksheets.
            (b)   Such worksheets must, at a minimum, include the calculations for the amount of bonus floor area requested.
            (c)   Such worksheets will serve as an official record of bonuses and such records will be binding on the property owners and their successors and assigns.
      17-7-0407-E Bonus Formula.
         1.   Floor area bonuses will be based on a financial contribution that reflects the value of land within the surrounding area, based on the following formula:
            Cost of 1 square foot of floor area = 0.50 x median cost of land per buildable square foot
         2.   The cost of land must be based on sale prices within the most recent 5 years, as provided by the Department of Planning and Development.
         3.   The Commissioner of Planning and Development is responsible for updating estimates of land values at least once every 5 years.
         4.   The bonus payment must be paid in full prior to the issuance of the first building permit for any building or buildings within the planned development; provided, however, if the planned development is constructed in phases, the bonus payment must be paid on a pro rata basis as the first building permit for each subsequent new building or phase of construction is issued. The amount due prior to the issuance of a building permit (whether for a single building or for any subsequent phase of construction) shall be calculated by multiplying the total bonus payment due for the planned development as a whole (as the land value determination may be adjusted from time to time pursuant to paragraphs 2 and 3 above) by a fraction, the numerator of which is the amount of floor area in the building or buildings for which the permit is then being issued and the denominator of which is the total amount of floor area approved in the planned development (calculated as the total maximum floor area ratio in the planned development multiplied by the total net site area in the planned development), as follows:
 
Bonus payment due at the time of applicable permit*
=
Total bonus payment for planned development**
x
Floor area approved for construction in building permit for applicable building or phase ÷ maximum floor area approved for construction in planned development as a whole***
 
*   Each payment is due prior to the issuance of the first building permit for any building or buildings in the planned development.
**   The total bonus payment shall be determined by calculating the amount of bonus floor area granted in the approved planned development times the amount per square foot due pursuant to Sec. 17-7-0407-E-l (as the same may be adjusted in accordance with Sec. 17-7-0407-E-2 and Sec. 17-7-0407-E-3), and therefore the final payment amount may change overtime.
***   Maximum floor area is calculated as the total maximum floor area ratio in the planned development multiplied by the total net site area in the planned development.
      17-7-0407-F Allocation of Bonus Payment.
         1.   Cash Deposit. Except as provided in paragraphs 17-7-0407-F-2 and 17-7-0407-F-3, all funds received for floor area bonuses under this Sec. 17-7-0407 shall be deposited in the following funds in the following amounts:

The revenues of the North Branch Corridor Bonus Fund shall be reserved and utilized exclusively in accordance with Sec. 17-7-0407-H-2.
         2.   Use of Funds.

         3.   Option for In-Kind Provision of Improvements. In lieu of the required cash contribution to the North Branch Corridor Bonus Fund, the planned development ordinance may authorize applicants to undertake qualifying improvement projects themselves, in furtherance of the goals in the North Branch Framework land use plan. The Department of Planning and Development shall review proposals for in-kind improvements on a case-by-case basis. If the Department of Planning and Development approves the proposal, the applicant shall submit project documentation, including but not limited to, detailed site-specific cost estimates for the improvements, appropriate drawings, detailed construction commitments, a construction schedule, and a performance bond for completion of the improvements, if applicable. If the estimated budget for the project exceeds the applicant's required cash contribution, the Department of Planning and Development may distribute funds from the North Branch Corridor Bonus Fund to the applicant to perform additional work associated with the project on behalf of the City or applicable sister agency, subject to city council approval.
         4.   Minor Change for Allocation of North Branch Corridor Bonus Funds. Changes to improvements specified in a planned development ordinance, or the substitution of one type of improvement for another, or the manner in which payments are made or satisfied under Sec. 17-7-0407-F, shall be deemed minor changes and may be permitted by the zoning administrator, as provided in Sec. 17-13-0611.
         5.   [Reserved.]
         6.   Binding Commitments.
            (a)   Sister Agency Agreements. Any sister agency that receives funds under this Sec. 17-7-0407 (whether from the City as a distribution from the North Branch Corridor Bonus Fund or from the applicant directly pursuant to Sec. 17-7-0407-F-2) must enter into an agreement with the City regarding the permitted use of funds. Any funds that remain unused upon completion of the project must be returned to the North Branch Corridor Bonus Fund and applied to other eligible project costs.
            (b)   In-Kind Improvement Agreements. If the Department of Planning and Development approves a proposal for in-kind improvements pursuant to Sec. 17-7-0407-H-3, the applicant must enter into an agreement with the applicable City department or sister agency specifying the type of improvements to be provided, the value of the improvements, the time line for completion of the improvements, the manner in which any supplemental funds will be used, and any other terms or conditions the Commissioner of Planning and Development deems necessary or desirable.
            (c)   Authorization.

17-7-0600 Special character overlay districts generally.
   17-7-0601 Purpose.
      17-7-0601-A The purpose of this section is to expressly authorize the establishment of special character overlay districts for neighborhoods that have unique or distinctive physical characteristics that are not generally present in other areas of the city, or to protect and guide development in areas that have distinctive neighborhood characteristics. Such unique or distinctive physical characteristics may come in the form of:
         1.   Size, shape or lot configurations that deviate greatly from the platting pattern found in other parts of the city;
         2.   Building types or architectural styles that conflict with base district standards, yet make a positive contribution to the physical character or livability of an area;
         3.   Environmental or other physical features that would prevent reasonable development under applicable zoning standards;
         4.   Identifiable and cohesive neighborhood unit possessing similar development patterns and physical characteristics (for example, building features, site design, land use patterns, and natural or streetscape characteristics); or
         5.   May be located adjacent (that is, as a buffer area) to an existing Chicago Landmark District.
      17-7-0601-B The special zoning regulations that apply within special character overlay districts are intended to reduce conflicts between new construction and existing development, encourage city beautification and conserve the character of the city's most unique neighborhoods. Special character districts are not intended to serve as neighborhood-specific zoning rules that modify zoning standards merely because of dissatisfaction with development that complies with otherwise applicable standards. Such situations should be addressed through consideration of amendments to base district zoning standards that would apply citywide.
   17-7-0602 Minimum Requirements. An area will be eligible for designation as a special character overlay district after a recommendation by the City Council Committee on Zoning, Landmarks and Building Standards if at the time of application it is located within any R, B, C, D or M district, and contains at least 4 contiguous acres of land area.
   17-7-0603 Authorized Regulations and Standards. Special character overlay district regulations may address any of the following:
      17-7-0603-A uses;
      17-7-0603-B floor area ratios;
      17-7-0603-C densities (lot area per dwelling unit);
      17-7-0603-D number of buildings on a zoning lot;
      17-7-0603-E lot area;
      17-7-0603-F building coverage;
      17-7-0603-G yards or setbacks;
      17-7-0603-H lot frontage;
      17-7-0603-I building heights;
      17-7-0603-J building entrances and/or orientation;
      17-7-0603-K exterior building materials and design;
      17-7-0603-L layout of public ways;
      17-7-0603-M vehicular and pedestrian circulation patterns;
      17-7-0603-N amount or location of parking and loading; or
      17-7-0603-O other zoning-related standards that are necessary to address unique zoning, platting or development features.
      17-7-0603-P district-specific design guidelines for rehabilitation, new construction, and additions published by the Department of Planning and Development.
      17-7-0603-Q rehabilitation of character buildings as outlined in district-specific design guidelines. Character buildings have unique historical, architectural, or other impact on the district environment. Rehabilitation of identified character buildings is a priority in accordance with Section 17-7-0601-A.
   17-7-0604 Procedure for Establishment. Special character overlay districts must be established in accordance with the procedures of Sec. 17-13-0500.
   17-7-0605 Variations/Administrative Adjustments. Within any established special character overlay district, applicants may seek authorized administrative adjustments or variations, pursuant to the applicable administrative adjustment or variation procedures of Chapter 17-13.
   17-7-0606 Special Uses. Within any established special character overlay district, any applicant may seek approval of a special use allowed by the base district or Special Character District standards. In such cases, the applicant must demonstrate that the proposed special use meets the general applicable approval criteria for special uses and that the proposed use will comply with applicable special character overlay district regulations.
