Sloping sites can present real problems including runoff and erosion. It can also be challenging to find ways to use this property. Sites like this can really benefit from the construction of a retaining wall to provide more level planting and recreation areas. limestone is the perfect choice for native stone in Kansas. It also happens to be the lowest cost per ton of any natural stone due to it being local and not having to be transported across the country. Irregular limestone retaining walls are often built at a further angle back into the slope to ensure stability. Little planting pockets can be created to plant a living wall; sedums and rock garden plants work great in this application.
