Preface:
It
is important to note that as the city of Los Angeles continues to
grow, that it's method of growth is different from most traditional
cities, which tend to grow from a center out. As it has been frequently
pointed out, Los Angeles is a city of edges and though its edges
are constantly being re-defined outward as well as within, much
of the city's growth is also taking place inwards from these edges,
filling in the gaps that have been left as a result of rapid expansion.
Like an adolescent growing into an adult suit, much of the space
in between is being accounted for by various forces which creates
a new urban condition for the city, and thus by connection for the
sites of LAUSD projects - a condition of increased density that
will continue to confront the schools of this District.
This was the
driving reality behind much of the discussions that took place at
this Symposium Session on site zoning and service access. With the
intent of equipping the District to better address and tailor solutions
for the facility challenges it faces as Los Angeles matures into
the premier city of the 21st century, this Panel had the following
observations and recommendations for the District.
Section
A:
The Panel identified the following issues as those
that defined the present site condition for many LAUSD projects:
1. Project site
size is continuing to be reduced relative to the size of program
desired. This is leading to a condition of higher density both in
the planning of the site and the building(s).
2. Project sites
are becoming increasingly land-locked with 2 or less public thoroughfares
at the perimeter, thus necessitating on-site access roads that can
further reduce the buildable area for the project's various program
functions.
3. As the location
of potential sites today do not always have the benefit of a pastoral
context (very few do anymore), a paradox has been developing where
a school needs to still present a friendly public face while providing
for an increased level of perimeter security.
4. The reduced
size of exterior space makes the ability to create an open exterior
environment increasingly difficult.
5. The location
of potential sites is increasingly in contexts where the project
needs to mitigate and form the transition between several different
communities of varying physical scales.
6. The increasingly
limited number of potential sites has led to fewer sites with the
opportunity for advantageous building orientation as it relates
to natural light and energy consumption.
7. Need for
public access to certain multi-use functions of the school has impacted
architectural planning strategies. These multi-use functions are
available primarily to the public during the nighttime.
8. Community
meetings that solicit more feedback from those with self-interests
as opposed to the neighborhood users can negatively impact the site
and architectural planning strategies of schools.
9. Small to
almost non-existent landscape and landscape maintenance budgets
are depriving schools of a valuable tool in addressing many exterior
grounds issues.
Section
B:
The Panel recognizes that the cause for a majority
of the issues stated in Section A is due to the increased scarcity
of available sites for school projects. As such, the Panel accepts
this reality and chooses an attitude of embracing it as a platform
for making the following recommendations to the District (number
preceding each recommendation below corresponds to the number preceding
each of the issues in Section A above.):
1. Recognize
that school buildings of higher density can have the following benefits:
more efficient planning; relatively more open exterior space by
concentrating the building within a smaller portion of the site;
a more close knit social community that comes from a denser physical
environment; and given the appropriate neighborhood context, a multi-story
building could be of a scale that gives the school a more public
presence and identity befitting of a civic institution. Also consider
the strategy of stitching together various smaller sites within
close proximity to each other with pedestrian bridges and/or thoroughfares.
In extreme cases of density, rooftops of schools could also be better
utilized; presently the District's policy of primarily relegating
rooftops for HVAC units prohibits them from being better used -
more serious consideration for central plants or relocating the
HVAC units to parking decks could help liberate rooftop space for
a variety of exterior program functions.
2. Locate on
site access roads within the property setback zones so as to preserve
the maximum buildable area of the site. Have shared vehicular circulation
for on site access roads whereby they provide for fire, service,
as well as parking access, thereby minimizing access points off
public thoroughfares. Consolidate but still keep separate public
points of vehicular entry - public drop-offs and bus stops - to
maximize the use of the common edge(s) between the school and public
thoroughfares. The separation between service and public access
still needs to be maintained but public surveillance of both is
preferred. Given the appropriate context, exterior playgrounds can
also serve as service and fire access ways creating another layer
of shared use. Where possible, consideration needs to be given to
extending the spirit of shared use to adjacent community parks and
playfields. A positive collaboration with the Parks and Recreation
Dept. would benefit this cause; the issue of who maintains these
shared parks and playgrounds would need to be determined.
3. In the appropriate
context, use the buildings to form the security edge by pushing
them out to the site's street edge. This approach would also provide
sound buffer benefits as well though it may require the budget for
these buildings to be increased. Such a strategy would also provide
the opportunity for the school to gain more of a civic identity
as well as minimize the perimeter fencing that can communicate an
unfriendly neighborhood presence by creating a no-man's land for
trash and other unsightly elements between the street and the buildings.
Use of landscape can soften the edge between the building(s) and
the street, and ground level security on and natural lighting for
the public side of the building can be addressed with clerestory
windows and the like.
4. The reduced
size of exterior space calls for a different attitude towards the
character of that exterior space; exterior space can take on a denser
character, such as an outdoor room, but one must take care to control
where that dense exterior space is. It is advantageous is to locate
such exterior space(s) along a major exterior circulation route
for the school, perhaps within public view of the street, and/or
adjacent to classrooms whose functions can utilize this space as
a break-out area. Such strategies will help insure that this space
is used and thereby be active as an enlivened public exterior space
for the student body.
5. Where possible,
attempt to locate the buildings in those areas of the site that
border the larger scale public/commercial buildings and locate the
fields and playgrounds adjacent to the residential scale neighborhoods.
6. Serious consideration
needs to be given to making sure that if the site does not accommodate
the proper orientation, that the project budget allows for the provision
of adequate passive solar elements; not doing so can result in higher
operating costs due to energy consumption. Sites that offer the
opportunity for proper building orientation is still preferred.
7. Locate these
multi-use functions on or near the street, and establish clear zoning
for them by designing the building(s) to form spatial thresholds
between the multi-use functions and the rest of the school. This
spatial "pinch" (as referred to by the Panel) would ideally
then necessitate only a gate at the threshold and thus minimize
fencing. Direct access to public parking is a paramount to the success
of these multi-use functions. The strategy of site planning the
school around the concept of separate pavilions to isolate the building(s)
which serve the public after hours was explored, but it was commented
that such a site planning strategy could increase fencing for site
security reasons and thus detract from the benefits stated in Section
B, Item 3 above.
8. The spirit
and purpose of community meetings needs to be maintained, but attempt
to schedule them in the afternoon and not in the evenings. It was
observed by the Panel that afternoon meetings tend to draw more
users, which makes for a more constructive dialogue; evening meetings
tend to be dictated by those members of the community who are governed
by their own self-interests.
9. Landscape
budgets for both construction and maintenance needs to be increased.
Increased use of landscape is a cost-efficient and constructive
method for upgrading the school's outdoor environment and community
identity while providing other practical benefits such as security
and acoustics.
Conclusion:
The
above recommendations are to serve as guidelines, not rules as the
Panel recognizes that they may not all be applicable to every site
under the District's consideration. As the available sites for future
LAUSD projects become more restrictive, their unique conditions
can become more numerous, and allowances need to be given to schedule,
budget and the like to account for them. Thus the Panel believes
that it may be in the District's best interests to enlist the services
of the architectural profession to examine the sites under project
consideration on a case by case basis for the following reasons:
· To
assist the District in using these guidelines to determine which
sites are more appropriate for future projects.
· To advise the District as to which of the above guidelines
are applicable to any given site.
· Once the above is established, to assist the District in
determining the appropriate budget for a given project given its
particular site conditions.
This all said,
one of the most important questions still facing the Panel is how
to best disseminate the above information to the District; beyond
the White Papers for each of the 16 sessions, a forum with the District
where these issues could be discussed in a focused and directed
manner deserves serious consideration.
