City of San Diego General
Plan Update
Strategic Framework Element - Draft Alternative Growth Strategies
To achieve
the projected SANDAG 2020 forecast, the existing policies (current
City community plans applied over the 1995-2020 period), would
need to increase from approximately 124,000 housing units to
177,500 housing units, representing a 43% increase. The following
Draft Alternative Growth Strategies were developed to accomplish
this increase of 53,500 housing units beyond current City residential
designations.
Proposed Alternatives for Strategic Framework
Citizen Committee Review and Discussion:
- SANDAG's "Smart Growth" Alternative
- A City of Villages
- Strong Core with Subregional Centers
- Annexation/Acquisition/Conversion
- Expanded Downtown Core
Draft Alternatives
SANDAG's "Smart Growth" Alternative
Growth Strategies
SANDAG's
"Smart Growth" Alternative is based upon the Land Use
Distribution Element and locates higher residential densities
(minimum average net density of 20 units per acre) as well as
mixed uses within walking distance (1000 foot radius) of the
existing and planned transit stations. It assumes that all future
residential development will occur at the top end of the density
ranges expressed in existing plans, and it applies the County
planning group limitations on residential development in the
unincorporated area. The projected residential capacities identified
by SANDAG are for 39,625 Single Family units and 137,875 Multiple
Family units (totaling 177,500 units). Of the 177,500 housing
units, 107,226 would occur on vacant land (average density of
6.5 units per acre), and 70,274 would be redevelopment or infill
(average density of 20.4 units per acre). By focusing development
in mixed use centers around rail transit stations and in major
bus corridors, more trips can be made by transit, walking and
bicycling.
A City of Villages
This
alternative involves creating village centers in 20-40 key neighborhood
centers. These centers would range in size from 10 to 160 acres.
Design would be pedestrian-friendly with elements to promote
neighborhood gatherings. The land use mix would include neighborhood
shopping, services and housing, as well as significant village-serving
public spaces. Village centers could also include an employment
component. These moderate intensity (18-45 dwelling units/acre),
mixed-use village centers would be linked to each other and to
the region through high quality rapid transit services designed
on a network structure.
Strong Core with Subregional Centers
This
alternative calls for focusing residential and employment growth
in selected urban nodes, including Centre City, the northern
portion of University ("the Golden Triangle"), Mission
Valley, Sorrento Valley/Mesa, Kearny Mesa, and Otay Mesa. These
multi-modal urban nodes will have a relatively high degree of
land use balance and self-sufficiency. This would entail increasing
densities in existing residential areas, and the addition of
a residential component to Sorrento Valley, Kearny Mesa and Otay
Mesa employment areas. The density range would be 25-75 dwelling
units per acre. This alternative requires an expanded transportation
system, including road, pedestrian, bicycle, and transit components.
It also reinforces the importance of Centre City as the administrative,
financial, cultural and institutional center of the region.
Expanded Downtown Core
This
strategy calls for a substantial expansion in downtown's role
as the dominant employment, shopping, entertainment, hotel and
high density residential center of San Diego. The physical boundaries
of downtown would expand and could ultimately include portions
of the surrounding communities of Little Italy, Middletown, Golden
Hill, Sherman Heights, Barrio Logan, Logan Heights and Lindbergh
Field. Within downtown there would be an inner core area in the
traditional center city area south and west of I-5 with very
high density commercial, office and residential areas designed
to be pedestrian and transit oriented. Densities in the inner
core would be up to 250 du/acre [dwelling units per acre] with
a minimum permitted density of 125 du/acre for new development.
The peripheral portions of downtown would have varied density
maximums ranging from 100 to 200 du/acre with a minimum of 25-50
du/acre. The lower densities would be in existing residential
areas with significant historic resources and neighborhood character.
The information infrastructure network would be expanded to permit
downtown to become a major high tech hub for the San Diego region.
Adjusted standards and reduced acreage requirements for schools
and parks would be increasing to implement this alternative.
Annexation/Acquisition/Conversion
This
strategy would provide additional land to accommodate pedestrian
and/or transit oriented development in locations such as east
Otay Mesa, Miramar, Lindbergh Field and elsewhere. Comprehensive
planning of Otay Mesa under a single jurisdiction would facilitate
efficient phased provision of utilities and roads and coordinated
land use policies throughout the geographic area of Otay Mesa.
Use of portions of Miramar and Lindbergh for urban development
in the future is dependent on decisions of the federal government
regarding the future use of Miramar as a military base. If military
use is discontinued at some time in the future, a portion of
the base could be converted into a commercial airport to replace
Lindbergh Field. Lindbergh Field and portions of Miramar MCAS
could be redeveloped with urban and recreational uses. The City
could also make available existing underutilized city owned land
and acquire additional underutilized parcels for desired uses.
Proposed Alternatives for Additional Staff
Review and Analysis
Existing Trends
Continuing
business as usual following existing development trends and community
plans with a core downtown.
Slow Growth
Limiting
residential growth to the national growth average of 1% per year
compared to San Diego's current growth rate of 2% per year (through
zoning, growth caps, stringent phasing, and deterring employment
growth)
General Residential Intensification
This
Alternative assumes an equal distribution of density on the remaining
net developable residential acreage in each community plan area.
Based on the March 2000 SANDAG 2020 Cities/County Forecast Land
Use Inputs, an overall density of approximately 11 dwelling units
per acre would result by applying the net residential acreage
by community plan across the board to vacant residential acreage.
