Mixed use

Mixed use: is defined as development that involves a mixture of more
than one land uses or any combination of commercial uses such as retail and
non-commercial uses (e.g. residential) mixed within in a single building
(vertically or horizontally). This concept enables a range of land uses
(residential, commercial and industrial) to be co-located in an integrated way
that supports sustainable form.

In recent years many planning strategies have been selected
for re-establishing and to create a mixed-use neighborhood, the thrust of the mixed-use
is to have trading, employment and housing combined in the neighborhood to
assist public transit use and encourage parking and maintain public space.

Mixed use will a by providing a mix of uses of a neighborhood
like residential retail recreation in close proximity. After that the daily
need within a walking distance will appear, that means this will allow people
to stay in the neighborhood to meet there daily need.

The purpose of mixed land use

The purpose of the mixed land use is to provide local jobs and raise the
local economy and decreases the car dependency, support pedestrian, and cyclist
traffic, providing closer public services, reduces shattering of the landscape
and helping in the development of mixed communities.

 

How can mixed land-use be successful?

Successful mixed use area would be achieve if locating these development within
easy walking distance 400m (5 minute walking) with good quality of public
transportation from any dwelling , providing an area of development that have
mix night and day time activities for residence, ensure that transportation
network with adjoining development is integrated with mixed use development,
providing open space and recreation areas, ensure the street furniture,
signage, lighting, footpath treatment with safe road crossing that provide
safety for all users

Its benefit to the public is to develop all kinds of need, including (housing,
employment, business, investment, etc.) so they can the 1990s in one location
which makes the life much easier and reduce the usage of transferring methods
like cars.

 

 

The figure above shows the concentration and diversity of
activities concerning having a sustainable mixed-use, through vitality there
will be a more cleaner and secure environment which in-turn might make town
centers quality better as well as increasing the element of attractiveness, while
at the same time the mixed-land use means having a less need to travel because
of the closeness to every amenity and service, and less relying on owning a car
as a mode of transport while at the same-time there will be more use of the
public transport for social, economic and environmental benefits in other words
(sustainability).

Safety: while mixing residential, commercial and other professional activities
in a limited area, it creates safety, and will be more secures when people do
their activities during the day an evening, For example, people who live in
apartments that are built above stores will reduce the possibility of vandalism
during off hours.

Types of mixed-use

Vertical mixed use it consists of different uses in the
same building, the lower floors usually have more public uses (e.g.
retail/ commercial), and
private uses on the upper level (E.g. residential).

 

Horizontal mixed use is a group of close buildings on a
single site where each building used for a specific purpose. Horizontal mixing
of uses encourages building renters and the public to walk through communal
space to other buildings.

 

Walkable area mixed uses: it means a combination of both vertical and
horizontal mix of uses in a single area, with high integration between
different uses.

 In the 1950s one research was done on land use
in Central Business Districts according to that research the distribution was
68 percent is the floor area allocation for economic uses, 22 percent for
residential use and 10 percent for public service use.

This table shows the
summary of floor area allocation in several CBDs.

Residential area is the most important part in mixed-use
concept, For example 1990s the inner of Los Anglos was on the wane, but people
were back to the center of the city after reforming the city by applying
mixed-use concept

 

 

 

 

 

 

Requirements and guidelines for mixed-use

Thus, variant scales of multiple uses should be defined upon
the development’s size and location; in addition to that, design standards
should be distinguished from the different developments… A neighborhood with
many usage or mixed-use is an development that is not less than 40 scares in
gross land area and might be located at any location within the city

The suggestion for the mixed-use project in sustainable
neighborhood is: 40 to 60 percent for economic use, 30 to 50 percent for
residential use and 10 percent for public services. There are many standards
for flexibility so that every city applies them according to their own
situation and needs. Based on the difference in scale and context, all
standards for a mixed-use will not be equally applicable to all mixed-use
developments
