'''<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
