'''<h3>Making it happen: Approaches to getting LID into parks </h3>'''
The scale of your LID project will largely determine how you
will proceed. This guide provides two tiers of LID park retrofit
projects. You can usually complete small-scale LID projects
with in-house expertise and resources. Large-scale projects
will require external support from consultants and contractors.
'''<h4>Small-scale projects</h4>''' [[File:Example4.jpg|thumb|upright=0.6|A no-mow zone is a landscape alternative that

Starting with small-scale projects is a good strategy to
increase public interest in LID practices, gauge municipal
support, and gain experience. Small-scale projects include
retrofitting your parks site with landscape alternatives or rain
barrels, or using pollution prevention strategies and practices.<br>
Small-scale projects require fewer resources and require a
smaller project budget because:
* They do not require integration into capital works projects
* Engineering consultants are not required
* Contractors may not be not required
* External approvals are not required
* Consultation with the public is limited
Due to the less significant financial commitment, it can be
easier to build colleague and supervisor support for small-scale
projects.<br>
Small-scale projects like landscape alternatives and pollution
prevention may not be easily identified as LID practices by
the public. Your project team should consider establishing
educational signage to inform the public.<br>
'''<h4>Large-scale projects</h4>'''
Large-scale projects require significantly more effort, budget,
and staff than small-scale projects. Large-scale LID projects
include:
*Bioretention
* Enhanced grass swales
* Bioswales
* Perforated pipe systems
* Permeable pavement
* Soakaways
* Infiltration chambers
* Rainwater harvesting (excluding rain barrels)
* Prefabricated modules <br>
Consider a large-scale project if your municipality or
department would like to be a leader in sustainability. Largescale
projects are often highly visible and attract more public
attention. Large-scale projects may also be the only solution to
site-specific challenges. For example, if the parking lot on your
site does not have existing stormwater controls, small-scale
projects are not likely to fully achieve compliance with water
quality and quantity objectives. Consider using an infiltration
chamber or bioswale project to meet those objectives.
Before starting a large-scale retrofit project, consider the
following distinctions that set these retrofits apart from smallscale
projects.<br>
'''<h4>Integration with capital works programs</h4>'''
Most large-scale LID retrofits must function with existing
site infrastructure, such as storm sewers, catch basins,
and pavement systems. The construction of large-scale
LID practices often requires these systems to be removed,
exposed, or replaced. The best time for this type of project to
occur is when an infrastructure replacement or rehabilitation
project is already planned.
For example, installing bioretention, infiltration chambers,
or permeable pavement in a parking lot requires removal of
existing pavement. Budget and resources set aside for parking
