This does not indicate that you need to use every concept to every part of your strategy. However simply having an understanding of these concepts will allow you to create concepts and increase your imagination.
Low Impact Development LID is an innovative stormwater management approach with a basic principle that is modeled after nature: Techniques are based on the premise that stormwater management should not be seen as stormwater disposal.
Almost all components of the urban environment have the potential to serve as an IMP.
This includes not only open space, but also rooftops, streetscapes, parking lots, sidewalks, and medians. How did LID get started? Today, bioretention is just one of the LID techniques available to users. Other techniques, such as permeable pavers, tree box planters, and disconnected downspouts, will all be presented here on the LID Design Site to help users control pollutants, reduce runoff volume, manage runoff timing, and address a number of other ecological concerns.
Why should I use LID techniques? LID has numerous benefits and advantages over conventional stormwater management approaches. In short, it is a more environmentally sound technology and a more economically sustainable approach to addressing the adverse impacts of urbanization.
By managing runoff close to its source though intelligent site design, LID can enhance the local environment, protect public health, and improve community livability - all while saving developers and local governments money.
The need for such an approach has never been greater. Stormwater programs require that a wide array of complex and challenging ecosystem and human health protection goals be addressed. Many of these goals are not being met by conventional stormwater management technology, and communities are struggling with the economic reality of funding aging and ever-expanding stormwater infrastructure.
The challenge of how to restore stream quality in watersheds that have already been densely developed is even more daunting. LID provides the key in its emphasis on controlling or at least minimizing the changes to the local hydrologic cycle or regime.
Local permitting agencies can use LID as a model in revising local zoning and subdivision regulations in favor of more cost-effective, ecologically sound development practices. Developers can achieve greater project success and cost savings through the intelligent use of LID, and designers can apply these techniques for innovative, educational, and more aesthetically pleasing sites.
What are the costs associated with LID? A common concern is that LID-based projects will be more expensive because they could require higher design and construction costs and a longer time to receive project approval.
This may or may not be true, depending on the experience of the project consultants and contractors with these new techniques and the receptiveness of local government officials to innovative practices. These potential cost increases are not indictments of the concept of LID but of inexperienced institutions, individuals, and bureaucracies that remain unaware of the great necessity for and benefits of a new approach.
For example, several years ago there were only a few permeable paver options available. Today, the consumer can choose from a large number of these innovative materials, and more widespread usage and acceptance of the technology has led to lower costs.
Additional LID cost concerns include the potential for greater expenses due to the increased use of on-site landscaping material. Despite these issues, experience has shown that LID still saves money over conventional approaches through reduced infrastructure and site preparation work.
This savings is achieved by reductions in clearing, grading, pipes, ponds, inlets, curbs and paving. Far outweighing any of the cost increases due to the use of LID, these infrastructure reduction savings enable builders to add value-enhancing features to the property, to be more flexible and competitive in pricing their products, or even to recover more developable space since there is no need to waste land for a stormwater pond.
Costs are very site specific. Here, on the LID Design site, fairly exact cost estimates are given for some of the individual techniques.
Keep in mind, however, that the actual costs will vary greatly based on the character of the individual site and the creativity of the designer! Some commonly seen cost benefits of LID projects include: Multifunctionality - In many projects, the LID practice was originally designed as a landscaped feature before its functionality as a stormwater control was introduced.
In these situations, the landscaping and construction costs for stormwater are essentially free. Additionally, the cost of maintaining the landscaped areas was always expected for the project, so one of the only major additional costs for stormwater maintenance is to ensure that drainage areas are kept clear.Universal Design for Learning (UDL) is a research-based set of principles to guide the design of learning environments that are accessible and effective for all.
There are six principles of design that have been used by artists for centuries throughout all art forms, painting and floral design as well as landscape design. They are: Balance; Focalization; Simplicity; Rhythm and Line; Proportion; Unity; 1.
Balance. Balance is a state of being as well as seeing. Low Impact Development (LID) is an innovative stormwater management approach with a basic principle that is modeled after nature: manage rainfall at the source using uniformly distributed decentralized micro-scale controls.
