Additional Amendments

Green Development Plan Concept: Alternative to “base zone development standards” of Zoning Code (section ) Provides comprehensive design approach to 6,500 feet of greenway including dual/split trail system, habitat enhancements, active and passive use areas, and in-water facilities GDP developed in partnership with City and individual developers producing incentives regarding maintenance and capital cost benefits

Green Development Plan History: Concept Adopted in 2002 as part of South Waterfront Plan Phase I – Project Goals adopted by Planning Commission and City Council 2003 GDP Schematic adopted by Planning Commission, Design Commission, and City Council 2004 Implementation strategy (governance and financial Plan) developed 2004 – 2007, to be reviewed by City Council in Winter 2008 Zoning implementation package Spring 2008

Planting types Green Development Plan:

Required Residential Development Areas Section Intended to “promote new housing in areas suitable and attractive for housing.” New development must include at least 1 dwelling unit per 1,000 sq. ft. of net site area (43 units per acre or about 40 units on typical block in South Waterfront).

Required Residential Development Areas Recommend Repeal required residential development area provisions applicable to South Waterfront Amend Map to remove required area Basis Residential development is successful in district and occupies most of target area. Other portions of target area now a focus of institutional uses which require an unnecessary and costly “modification” to requirements to be approved by City.

Retail Sales and Service Use Restrictions Section Intended to “promote neighborhood-serving commercial development and help reduce traffic congestion associated with large-scale retailers.” Allows retail uses up to 40,000 sq. ft. by right and up to 60,000 sq. ft. as a conditional use. Code defines hotels as a retail use.

Recommend Amend Zoning Code to exempt “Hotels” from the requirements of Section regarding retail sales and service uses over Basis Hotels have similar trip generation and transportation impacts as residential uses which are allowed outright in district. Retail Sales and Service Use Restrictions
