− | The scale
| |
− | of your LID retrofit project will largely determine how you will
| |
− | proceed. 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.
| |
− | | |
− | ===Small-scale projects===
| |
− | | |
− | Starting with small-scale projects is a good strategy to
| |
− | increase interest within your community, determine if
| |
− | support is available from stakeholder groups and gain retrofit
| |
− | experience. Small-scale projects include retrofitting your
| |
− | property with landscape alternatives, rain barrels or using
| |
− | pollution prevention strategies and practices.
| |
− | | |
− | Small-scale projects require few resources and a
| |
− | small project budget because:
| |
− | * They do not require integration into capital works projects
| |
− | * Engineering consultants are not required
| |
− | * Contractors are 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 the case for support for small-scale projects.
| |
− | A successful small-scale LID retrofit project on your property
| |
− | is a good indication that you are ready to take on a more
| |
− | intensive retrofit project. You now know the resources that Large-scale projects
| |
− | Large-scale projects require significantly more effort, budget,
| |
− | and staff than small-scale projects. Large-scale LID retrofits
| |
− | include:
| |
− | * Bioretention
| |
− | * Enhanced grass swales
| |
− | * Bioswales
| |
− | * Perforated pipe systems
| |
− | * Permeable pavement
| |
− | * Soakaways
| |
− | * Infiltration chambers
| |
− | * Rainwater harvesting (excluding rain barrels)
| |
− | * Prefabricated modules
| |
− | * Green roofs
| |
− | | |
− | Consider a large-scale project if your place of worship is
| |
− | striving to be a community leader in sustainability. Large-scale
| |
− | projects are often highly visible and attract more public
| |
− | attention. They may also be the only solution
| |
− | to site-specific challenges, like poor drainage. Before starting
| |
− | a large-scale retrofit project consider the distinctions that set
| |
− | these retrofits apart from small-scale projects.
| |
− | | |
− | ===Integration with long-term infrastructure replacement and rehabilitation plans===
| |
− | | |
− | 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 is when an infrastructure replacement or rehabilitation
| |
− | project is already planned.
| |
− | Maintenance programs and budgets that take into consideration
| |
− | the expected life cycle of critical site components, including
| |
− | parking lot and roofs, are valuable resources for large-scale
| |
− | projects. If the replacement of these features is forecasted in
| |
− | your site budget well in advance, asses if it is advantageous
| |
− | to incorporate LID retrofits into these projects. Remember,
| |
− | sharing construction materials, construction equipment, staff
| |
− | resources, and time will reduce the budget for your retrofit.
| |
− | For example, installing bioretention, infiltration chambers,
| |
− | or permeable pavement in a parking lot will require the
| |
− | existing pavement to be removed. Budget and resources that
| |
− | have been set aside for a parking lot replacement could be
| |
− | transferred to the LID retrofit project.
| |
− | | |
− | ===Involvement of consultants and contractors===
| |
− | | |
− | Consultants are required for large-scale retrofit projects,
| |
− | specifically for the final screening of options, pre-design,
| |
− | detailed design, tender and contract documents, construction
| |
− | supervision and administration, and assumption and
| |
− | verification.
| |
− | | |
− | Site contractors are also required for large-scale LID retrofits.
| |
− | Contractors should be pre-qualified based on previous
| |
− | experience with similar LID projects.
| |
− | | |
− | External approvals
| |
− | Large-scale retrofits may require a variety of approvals at the
| |
− | municipal, watershed, provincial, and/or federal level.
| |
− | Since LID is still relatively new, you may encounter policies
| |
− | or bylaws that present barriers to LID retrofit projects.
| |
− | Alternatively, the municipality may have to amend or enforce
| |
− | some policies and bylaws to facilitate the implementation of
| |
− | LID projects on your site.
