(1) Purpose and intent. The purpose of the design standards of this chapter is to provide the public, building and design professionals, and decision-makers with objective criteria for eligible new residential and mixed-use development in the city. The intent is to provide clear design direction that enhances La Mirada's residential character, allows for design flexibility, and ensures a high-quality living environment. It is in alignment with the goals of the city and state to address the housing affordability in this community.
(2) Applicability. The provisions of this chapter shall apply to multi-family and mixed-use residential development in all zoning districts that qualify for streamlined, ministerial processing pursuant to California Government Code Section 65913.4, as well as any other multi-family or mixed-use development project that qualifies for objective, ministerial review pursuant to State housing law.
(A) This chapter provides objective design standards required for use in the review of "housing developments" of two or more residential units governed by California Government Code Section 65913.4 (Streamlined Ministerial Approval Process) and "housing development projects" as governed by California Government Code Section 65589.5 (Housing Accountability Act). These sections detail the review processes required for projects that provide, generally, either affordable or market rate multi-family housing development projects with at least two units or mixed-use development projects with at least two thirds square footage designated for residential uses.
(B) These objective design standards are intended to apply exclusively to multifamily and mixed-use residential developments streamlined by State housing laws. These objective design standards do not apply to any other land development type, including detached single-family dwelling units. Developments proposing detached dwelling unit product types or any other land development types are subject to the applicable objective standards found in other relevant regulatory documents and sections of code.
(C) Modification or expansion of an existing conforming structure used for multi-family housing or mixed-use development that includes attached units is also eligible to use applicable standards of the Multi-family Housing and Mixed-Use Development Objective Design Standards Manual.
(D) For full eligibility criteria, see the California Government Code sections listed above or the city's development application materials.
(3) Consistency with other applicable objective standards. Projects shall comply with all objective city policies, development standards, and design standards as established in the General Plan, the La Mirada Municipal Code, and as applicable the Imperial Highway Specific Plan. Projects shall meet objective standards in this chapter in addition to all pertinent requirements of the La Mirada Municipal Code, such as Chapter
21.18, Residential Zoning Districts, and the Imperial Highway Specific Plan. If there is any conflict between these objective standards and other city and/or state objective standards, the less restrictive objective standard applicable to the project shall apply.
(4) Permit required. Any eligible project processed pursuant to this chapter shall require a site plan review design review of projects processed pursuant to this chapter shall be conducted by the appropriate approving authority and shall only include consistency with adopted objective design standards. Additionally, no findings shall be required for approval of the project.
(b) Site design. Site design refers to the arrangement of – and relationships between – buildings, parking areas, common and private recreational space, and pedestrian connections. The site design standards in this chapter address site layout and building placement, vehicular surface parking and access, pedestrian circulation and access, landscaping, and private and common recreational space. A project application shall follow objective requirements of the base zone it is located in, such as setbacks and building height.
