This chapter establishes the Lindenville Specific Plan district (and associated zoning districts) and provides for coordinated planning and design principles within this district.
A. 
The Lindenville Specific Plan districts are established to implement the Lindenville Specific Plan, which is incorporated herein by reference. The Lindenville Specific Plan is a comprehensive, long-term planning document for the Lindenville Specific Plan area. It includes land use districts and programs; design and development standards; open space standards, and guidelines; complete street standards; and infrastructure and utility enhancement; among other components.
B. 
Consistent with the vision established in the General Plan, the Lindenville Specific Plan implements the goals and policies through the following cross-cutting strategies:
1. 
Establish areas to create character, distinction, and visual interest within Lindenville.
2. 
Create a vibrant and inclusive mixed use neighborhood where people can easily reach destinations within a short walk or bike ride.
3. 
Promote a variety of housing types with distinct height and density standards to support a diverse range of families and households.
4. 
Maintain and strengthen Lindenville as a diverse economic engine that supports economic prosperity for all.
5. 
Design a multimodal, safe, and connected transportation network that advances sustainability and livability goals.
6. 
Promote arts and cultural uses.
7. 
Adapt to a changing climate by requiring resilient design and upgrades in areas impacted by storms and sea level rise.
8. 
Create new publicly accessible open spaces that encourage active and passive recreation to accommodate the physical and social needs of all users.
9. 
Protect residents and employees from air pollution, noise, and industrial pollutants present in the soil.

Ground floor nonresidential uses may be exempt from the maximum FAR, see Section 20.040.009 ("Determining Floor Area Ratio"). Ground floor nonresidential uses would count towards the minimum FAR.
B. 
Nonresidential Development. Floor area ratio (FAR) is used to regulate nonresidential developments and/or the nonresidential component of a mixed-use development.
1. 
In Zoning Districts that allow residential uses, minimum residential density must be achieved before nonresidential uses are permitted.
2. 
The Base Nonresidential FAR is used as the base FAR for office, R&D, and industrial development.
3. 
Additional FAR may be awarded, up to the Maximum Floor Area Ratio with Community Benefits, for developments that meet the following requirements:
a. 
Provide community benefits as established in Zoning Code Chapter 20.395 ("Community Benefits Program").
b. 
Contribute the open space on site and in designated locations in the Parks and Open Space Framework Plan in the LSP as part of its community benefits contribution.
