Section 2 - Statutory StatementsCommunity Asset Management - Section 428 Part 2 (D)General<strong>Council</strong> is currently implementing an electronic Asset Management System, which will allow a total reviewof all <strong>Council</strong> assets over the next 3 to 4 years.Local Collector and Regional Roads<strong>Pittwater</strong> <strong>Council</strong> manages 239.2 kilometres of local roads and 5.2 kilometres of regional roads. There arealso 33.4km of state roads for which the <strong>Council</strong> and RTA share responsibility.<strong>Council</strong> has in place a Pavements Management System. This forms the basis of future maintenance andrehabilitation of the road system.The <strong>Council</strong> prioritises maintenance work to ensure Category 1 roads (shopping centres, distributor roads)are kept in good condition, deteriorated roads are allowed to reach the minimum level of service before theyare rehabilitated or reconstructed and aims to maintain the other roads in at least a fair condition. A RoadPavement Management rolling 5 year plan has been formulated with a view to redressing all roads with apoorly rated Pavement Condition Index. This plan concludes in the 2008/2009 financial year and a new 5year plan has now been formulated.Kerb and Gutter<strong>Council</strong> currently has a total of 378 lineal kilometres of kerb & gutter or equivalent concrete drainagestructures.The majority of the kerb & gutter is less than 50 years old, and overall it has been estimated that the liferemaining is 50%. This estimated value will be more accurately assessed over future years. Between 2008-2009 conditional assessment rated the kerb and gutter as 70% good or better, 29% reasonable and 1%as poor.Footpaths<strong>Council</strong> currently has an estimated total of 80 lineal kilometres of concrete paths concentrated along majorroads, feeder routes and commercial centres, together with 7m of asphalt paths.Between 2008-2009 this network was considered to be in a safe and acceptable condition. It was estimatedthat life remaining for the overall network is 60% (to be refined as part of a detailed condition survey overfuture years). Conditional assessment of the network rated them as 97% reasonable and 3% as poor.Reconstruction of longer lengths of deteriorated old paths or for the current backlog of work was undertakenas part of the Capital Improvement Program. During 2008-2009, repairs were concentrated on eliminationof trip risks. Priorities were given to locations near commercial centres, schools, retirement villages etc.<strong>Council</strong> completed a program of recording the whole footpath network by digital imaging. In future, datacapture will allow priorities to be set and visual records to be kept and updated.Retaining WallsDuring 2008-2009, the <strong>Council</strong> had approximately 10,000 square metres of retaining walls of varioustypes of construction (stone, boulder, concrete, crib, etc.). This data will be refined over future years via adetailed condition survey, which will also review the current estimate of remaining life (75%) for all walls.It is important to note that past road construction has created many large, earth embankments that will overtime require the erection of retaining walls to support the adjoining land or road pavement.DrainageThere are a total of 23 main catchment areas within <strong>Pittwater</strong>. Drainage has been mapped using theMapInfo mapping system to complete the Asset Register. The Register has identified an inventory of some9,500 pits and established a total length of drainage lines at 188 km. In addition, there are 27 GrossPollutant Traps and 2.5 km of stormwater channels.During 2008-2009 data collection of five of the 23 main catchments assessing the condition of theassets to estimate their expected remaining life was completed. Further data collection of the remainingcatchment areas will continue over the upcoming years. This will enable more accurate projections for alife cycle review of the system.Maintenance expenditure for the year was undertaken predominantly on a reactive basis as repairs. Basedon a sample of <strong>Council</strong>’s engineering plans for road, drainage and subdivision works, the average lifespanof the drainage system has been estimated at approximately 25 years. Current pipe types and constructiontechniques will extend the life of the more recent lines and systems.The installation of an increasing number of gross pollutant traps has, while improving water qualitydischarges, increased the required maintenance expenditure.21
