Summary
Cambridge's zoning ordinance requires the Harvard Square Advisory Committee and permit-granting authorities to judge new development in the Harvard Square Overlay District against the published Harvard Square Development Guidelines before any variance, special permit or advisory consultation is approved.
20.53.2 Criteria for Advisory Development Consultations and Review of Applications for Special Permits and Variances. In reviewing applications for variances, special permits or development consultation reviews the permit or special permit granting authority or the Harvard Square Advisory Committee shall be guided by the objectives and criteria contained in the publication Harvard Square Development Guidelines [Document complied from the Guidelines for Development and Historic Preservation as contained in the Final Report of the Harvard Square Neighborhood Conservation District Study Committee, dated November 29, 2000 and the Harvard Square Development Guidelines, 1986], in addition to the requirements of Sections 10.30 (Variances) and 10.40 (Special Permits) and this Section 20.50.
Full Breakdown
300 series was a PUD/Kendall Square provision, not a downtown design-review requirement, so it was set aside. The actual binding local design-guide provision for Cambridge's principal commercial square sits in Article 20's Harvard Square Overlay District. 40. 40 process. 1(1)(c). 3 layers historic-preservation review on top: a National Register-eligible or Guidelines-identified "contributing building" gets added protection, and the Cambridge Historical Commission must find a contributing building not preferably preserved under the Demolition Ordinance before it loses that status. This is a design-guideline overlay, not a numeric dimensional standard, so it operates through advisory review and special-permit conditions rather than an automatic denial.
Violations & Fines
Proceeding to a building permit for a Harvard Square Overlay project without completing the required Public Advisory Consultation or Committee review under Sections 20.53.1 and 20.54.1 exposes the applicant to denial or delay of the certificate of occupancy; because the Development Guidelines are advisory criteria applied through the special permit and variance process, noncompliance is enforced by the Board of Zoning Appeal or Planning Board withholding approval rather than through a direct fine.
