by the Keeper of the Privy Seal. The Poddell Tax could be collected from the officers of St Patrick's Cathedral and residents of the cathedral close (later stated as the Liberty of St Sepulchre) and St Patrick Street, but also from residents of two full liberties, and even more broadly, from all living within the danger of flooding, and initially, it was limited overall only to "such tax ... as should be sufficient" but to 5 pounds per person. The geographic reach of the tax was later extended to Dublin Castle and the residents or businesses on both sides of any street on or with a drain linked to the Poddle, and capped at 1s in the pound of rateable valuation of the property, and at 3 pounds per house. The commission had as its chief employee an inspector at a salary of 10 pounds, who by 1836 also held the office of collector of taxes at a commission of 7.5%, and a non-statutory role of superintendent at a further salary of 25 pounds. The Registrar of the Diocese of Dublin acted as an unofficial secretary to the commission, for occasional substantial payments, while there was also a surveyor, and one of the commissioners acted as honorary treasurer. By 1836 the commission, being composed mostly of senior officials with many responsibilities, rarely held a quorate meeting (none had been convened successfully since 1830, at least). The Poddell Tax was either 6 pence or 1 shilling in the pound on 2,632 buildings, with 20 pounds required from St Patrick's Cathedral and 280 from Dublin Castle. At the request of four of the Poddle Commissioners, the Lord Lieutenant asked Dublin's Commissioners of Paving to consider taking on the role and powers of the Poddle Commission, and they accepted this task, proposing to discontinue the special tax except with regard to cathedral and castle. The transfer of powers was done in 1840 and the powers were later in turn transferred to Dublin Corporation. Suburban There have been issues with suburban flooding in more recent times, with serious floods in Harold's Cross and Kimmage in 1987, 1990, 1993 and 2011. Following the 2011 flooding the local authorities asked the Office of Public Works to prioritise study of the Poddle, and a Catchment-Based Flood Risk Assessment and Management Study was carried out by 2013, with three flood management proposals prepared as a result.
