Drainage in the park is not great and, during heavy rains, water frequently collects at lower points, often (at least in the recent past) flooding over into the street at the Caldercuilt Road/Rothes Drive corner.
During initial refurbishment (April 2014) the council parks department partially excavated a water catchment area towards the north-east corner of the park in an attempt to alleviate road flooding and (hopefully) to create a wetland area suitable for amphibians (frogs, toads, newts) and other wildlife species.
This has only been partially successful so far. Although the catchment area does hold back water during heavy rains, reducing flooding on adjacent roads, the water then seeps away and retention is insufficient to support amphibians. We are exploring various ways to solve this.
