Full description of works needed are attached. The Environment Agency owns circa 71 residential properties to which basic repairs and maintenance is periodically needed. Recent surveys have highlighted some underpinning work is urgently needed to Lock Houses at Sandford on Thames, Oxford, OX4 4YD; Days Lock, Little Wittenham, Abingdon, OX14 4RB and Cookham Lock, Odney Lane, Maidenhead, Cookham SL6 9SR. The causes are a combination of drainage problems causing water leaks, and the addition of extensions in the 1960s and 1970s with insufficient foundations resulting in differential movement.
