Evaluation and watching brief by S Hoad of MoLAS on land within the manorial estate of Rhodri ap Gruffudd, brother of Llywelyn ap Gruffudd the Prince of Wales until his death in 1282, and his descendants during the 14th century. Two undated postholes were revealed.

Evaluation by A Cetera of MoLAS, as part of an ongoing programme of site investigations undertaken prior to and during redevelopment. Only a single trench was investigated in this instance with no finds or features of archaeological significance being revealed.

Evaluation by H Knight of MoLAS revealed no finds or features of archaeological interest.

Evaluation by S Hoad of MoLAS in advance of the construction of a new community hall on the site of the graveyard in use between 1868 and the late 1920s revealed two grave cuts (which were not excavated) dating to the late 19th century.

Evaluation by J Vuolteenaho of MoLAS in advance of the installation of a new track revealed one area containing postholes representing either early activity, or an earlier fence alignment, and another with a small shallow feature and further postholes. Monitoring by S Davis during machine clearance around the area of the first set of postholes did not reveal any similar or associated deposits, but the concrete roof of either a basement or bunker was uncovered. Although not fully excavated, the structure was found to extend at least 2m below the present ground surface.

Watching brief by C Menary of MoLAS revealed that the site straddled both the gravel island and the alluvial flood plain. A layer of alluvium containing residual Roman finds could relate to flooding of the Roman settlement in the 3rd century, and a deposit of post-medieval dumping dating to 1740–1800 was possibly an effort to raise the ground level in this period.

Evaluation by S Gannon and C Cowan of MoLAS, and continuation of work that began in 2002. A number of late 19th century light industrial features were revealed, including a probable sawpit, and evidence of brick manufacturing. A possible former dock, consistent with the evidence contained on contemporary maps, was also located. A programme of building recording was carried out by A Upson in 2002–3 (but unreported at the time) on former military and civil boat-building structures of early to mid-20th century date.

Evaluation and building recording by A Birchenough of MoLAS revealed no below-ground finds or features of archaeological interest. However, the photographic recording works to two air-raid shelters provided a useful archive of unusual prefabricated structures prior to their demolition.

Evaluation by C North of MoLAS in advance of residential development revealed evidence of probable modern landscaping, but no evidence of archaeological activity.

Evaluation by C North of MoLAS in advance of residential development revealed a small palaeochannel, but no finds of archaeological interest.
