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:
         1.   maintain and permit critical service uses;
         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
         3.   NBCO-C, South subdistrict.

      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.

   17-7-0407 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:

         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 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.
