The IGBC Landscape Credit Natural Topography is a vital credit for any green building project, which emphasizes the preservation of natural topography and landscapes. Natural topography refers to the natural features of the site, such as hills, valleys, water bodies, and other ecological features. The aim of this credit is to reduce the adverse impact of development activities on the site’s natural features and ecosystems. This article outlines the step-by-step method to comply with the IGBC Landscape Credit Natural Topography.
Step-by-step Method:
- Site Analysis:
The first step in complying with the IGBC Landscape Credit Natural Topography is conducting a site analysis to identify the natural features of the site. This analysis will help you understand the site’s natural topography and identify areas that need preservation.
- Preserve Existing Topography:
The next step is to preserve the existing topography of the site as much as possible. This includes retaining the natural slope, contour, and elevation of the land. If grading is necessary, it should be done in a way that minimizes the disturbance to the existing topography.
- Use Native Plants:
Using native plants in the landscaping design is an essential part of complying with this credit. Native plants are adapted to the local climate and soil conditions and require less water and maintenance. They also provide habitat for local wildlife, which is crucial for maintaining the site’s ecological balance.
- Use Sustainable Irrigation Methods:
If irrigation is necessary, it should be done using sustainable methods such as drip irrigation or rainwater harvesting. These methods minimize water wastage and reduce the site’s dependence on potable water sources.
- Manage Stormwater Runoff:
Managing stormwater runoff is another critical aspect of complying with this credit. This includes designing a drainage system that reduces the amount of runoff and ensures that the water is properly filtered before entering nearby water bodies.
- Document the Compliance:
Finally, the project team must document the compliance with the IGBC Landscape Credit Natural Topography. This includes providing detailed plans and specifications, photographs, and other documentation to demonstrate compliance.
Required Documentation:
The following table summarizes the required documentation for complying with the IGBC Landscape Credit Natural Topography:
| Documentation | Description |
|---|---|
| Site Analysis Report | A report detailing the site analysis and identifying the natural features that need preservation. |
| Landscaping Plan | A detailed landscaping plan that shows the use of native plants, sustainable irrigation methods, and stormwater management techniques. |
| Stormwater Management Plan | A plan that describes how stormwater runoff will be managed on the site. |
| Photographs | Photographs that document the site’s natural topography and the landscaping design. |
| Compliance Report | A report that summarizes the compliance with the IGBC Landscape Credit Natural Topography. |
Conclusion:
Complying with the IGBC Landscape Credit Natural Topography is an essential part of any green building project. By preserving the natural topography and using sustainable landscaping practices, developers can minimize the adverse impact of development activities on the site’s natural ecosystems. The step-by-step method outlined in this article provides a framework for complying with this credit, and the required documentation ensures that compliance is adequately documented.
