A stage 1 or stage 2 application may request review and approval of one (1) or more building units, structures or open spaces, or of one (1) or two (2) buildings.
An applicant may request consideration of the stage 1 or stage 2 applications individually or through a consolidated review.
A stage 1 review will examine the specific arrangement of building units on the site, the specific location of open spaces, the massing and height of building units, the mix of uses, access to structures, the location of transportation ways, and access to and from the platforms, in accordance with the review criteria of Subtitle K § 323.
A stage 2 review will examine the outward appearance of building units, the design of landscape and hardscape, the functionality of transportation ways, and the general location of uses, in accordance with the review criteria of Subtitle K § 325.
A consolidated review will examine all the aspects of design mentioned in Subtitle K §§ 317.3 and 317.4, in accordance with the review criteria of Subtitle K §§ 323 and 325. An application for consolidated review shall include all submittal requirements listed in Subtitle K §§ 322 and 324.
A stage 1, stage 2, or consolidated application shall be determined by the Zoning Commission to be not inconsistent with the Comprehensive Plan, not inconsistent with the approved master plan, to provide for a mix of uses, to be acceptable in all other applicable review criteria as set forth in Subtitle K §§ 323 and 325, to generally further the purposes of the USN zone, and to comply with all other requirements of this chapter.
An approved stage 1, stage 2, or consolidated application may be modified through application to the Commission, and the application for modification shall be subject to the same approval criteria as set forth in Subtitle K § 317.6.
Upon the effective date of the Zoning Commission order granting approval of a stage 1 application, the applicant may apply for a building permit to construct any portion of the platforms related to that stage 1 application.
An applicant must return to the Zoning Commission for review and approval of a stage 2 application prior to applying for a building permit or beginning construction for any other portion of the approved stage 1 review application.
