If you are considering building on a shoreline bluff, ravine, low-bank marine or lake-front lot backed by a steep slope in the Puget Sound & Salish Sea region – the least expensive and most effective way to forestall future stormwater, erosion, or shallow landslide problems is to minimize clearing and grading and preserve native soils and plant communities during development.
If your bluff property has already been developed, you might have an inadequate setback, stormwater runoff and erosion problems, infestations of invasive plants, topped trees, and extensive lawns. You may be inheriting problems from past poor development and management practices. For instance, compacted soils and lawns that extend to the bluff edge can contribute to soil saturation and stormwater runoff, erosion problems, and destabilization of marginal slopes.
A combination of improved management practices, structural drainage measures, and vegetation enhancement could help to improve conditions and reduce the incidence and severity of landslides.
Whether you are developing a new home or improving an existing site, use of native plant species in your landscape design before serious problems occur (creating a distinctively Northwest landscape) can help you to minimize stormwater and erosion impacts, mitigate conditions which may trigger landslides, and give you greater peace of mind.
