Basic rear deck in Santa Cruz California that is obviously clogged with debris, making water runoff impossible.  Many times boards that have been built too close to one another, after years and years, will fuse together, making the removable of debris a potential impossibility.  This wasn’t the case for this eight year old deck on 14th Avenue.  If you’re having a new deck built, make sure your builder knows how to properly space the boards for the long haul.
