2 1. OBJECTIVES As a highway authrity we have a statutry duty under sectin 41 f the Highways Act 1980 t keep the netwrk available and safer fr ur custmers. We are als permitted under Sectin 58 f the Highways Act 1980 t use a special defence in respect f actin against us, t shw that we have kept the highway in reasnable repair. The Highway Inspectin regime has been develped in accrdance with the recmmendatins cntained in the Well-maintained Highways A Cde f Practice fr Highway Maintenance Management (July 2005). Our regime is set ut within a practical and reasnable framewrk f risk assessment and inspectin frequency, which takes accunt f all rad users, including thse wh are mst vulnerable. Our main bjectives are: Ea T lcate and identify defects n the highway and where apprpriate, adjacent t the highway and t priritise its repair. T assess the ptential risks f damage and / r injury t highway users that may result frm these defects. T ensure that apprpriate measures are put in place t manage, eliminate and minimise risk. T ensure that thse measures are effective in eliminating, r at least minimizing the risk. st Sussex Highways

3 2. IDENTIFICATION OF DEFECTS The table belw sets ut the varius defects t be identified in a safety and service inspectin. The defects are arranged in grups accrding t the element f the highway in which they ccur. The list is nt exhaustive and persns carrying ut the safety inspectins are requested t recrd any defect that might create a hazard t users f the highway. Element Carriageway Kerbing Ftways Furniture ** Trees and Vegetatin Verges* N defects External defect Defect Pthles Lse material (t include debris, spillages r cntaminatin) Regulatry markings faded and wrn Irnwrk, missing, brken, tilted, sunken r prjecting Displaced rad studs Edge damage n unkerbed rads Unevenness due t rutting, humps, crrugatins Lse, tilted, prjecting Pre-frmed unit paving rcking, trips r missing Pthles General surface defects trips, bumps, depressins etc. Irnwrk, brken, tilted, rcking, missing r prjecting Rails, barriers, safety fencing, fences, psts - excessive defects Rad signs and signals - excessive defects Unlawful signs safety hazard On the highway diseased, dead, dangerus all r part abut t fall Off highway safety hazard Surface defects Irnwrk / cvers, brken, missing r prjecting N relevant defects fund Third party, statutry undertaker defect * Verges primarily cnsist f sft sil / material and will als cntain natural undulatins, depressins, ditches, shrubs, branches, tree stumps and the like. They cannt be maintained t the same specificatins and standards as the metalled carriageway. ** Fr a large number f street furniture elements sme frm f prefabricatin wuld be required t achieve a permanent repair which may nt be pssible within 28 days. Under these circumstances the defect wuld be made safe until a permanent repair was pssible. Safety Interventin Levels Carriageway: High: Cat 1 Medium: Cat 2 Lw: Cat 3 (any defect in the carriageway, causing in a change in level, resulting frm raised r sunken irnwrk, pthle, failed surface) Greater than 100mm and at least 300mm wide in all directins Greater than 60mm and less than 99mm deep and at least 300mm in all directins Greater than 40mm and less than 59mm deep and at least 300mm in all directins NOTE: At all frmalised, pedestrian crssing pints and n carriageway cycleway, Ftway interventin levels shall be used.

4 Ftway: High: Cat 1 Medium: Cat 2 Lw: Cat 3 (any defect in the ftway r designated cycleway, causing in a change in level, resulting frm raised r sunken irnwrk, pthle, failed surface, displaced paving, kerb) Greater than 40mm deep and at least 200mm wide in all directins Greater than 30mm and less than 39mm deep and at least 200mm in all directins Greater than 20mm and less than 29mm deep and at least 200mm in all directins Pavements, Kerbs & Blacktp / Tarmac Pavements In defined Primary and Secndary Walking rutes where the adpted inspectin frequency is the same, repairs will be carried ut when a trip hazard f 20mm is either fund thrugh ur regular safety inspectins r where the fault is reprted t us by members f the public. Fr blacktp r tarmac pavements the trip hazard is defined as 20mm r mre in depth and less than 600mm (2 feet) in width r length. 20mm ( 3 / 4 inch) Trip hazard PAVED OR SLAB PAVEMENTS 20mm ( 3 / 4 inch) trip hazard Pavement DISPLACED KERBS Rad 20mm ( 3 / 4 inches) trip hazard Length r width less than 600mm (2 feet) BLACKTOP PAVEMENT

5 Rad r Carriageway On Strategic Rutes, Main and Secndary Distributrs where the adpted inspectin frequency is the same. Repairs will be carried ut where a pthle hazard f 40mm (1 ½ inches) r mre in depth and with an equivalent diameter f 300mm r ver, is either fund thrugh ur regular safety inspectins r where the fault is reprted t us by members f the public. 40mm (1 ½ inches) pthle hazard Mre than 300mm (1 ft) diameter ROAD SURFACE The fllwing is a schedule f defects t be identified during safety inspectins:- Missing warning and regulatry signs. Missing irnwrk cvers r gratings. Damaged safety fences/barriers impeding the highway r ftway. Damaged signs / street furniture which verhang the highway r ftway and which are likely t cllapse. Lse rad studs Cracks in ftways / cycleways wider than 25mm (1 inch) and lnger than 300mm (1 ft).

6 3. INSPECTION FREQUENCIES Categries f Inspectin Inspectins can be cnsidered under the fllwing tw categries: Safety Inspectin Inspectins t identify all defects likely t create danger t users r the wider cmmunity, and therefre requiring immediate r urgent actin. Service Inspectin - Inspectins t identify all defects likely t cmprmise serviceability and sustainability. Safety Inspectin Frequency Inspectin frequencies have been determined accrding t the netwrk hierarchy fr bth rads (carriageway) and ftways based n the Well-maintained Highways A cde f Practice fr Highway Maintenance, and are set ut in the tables belw. Feature Descriptin Netwrk Hierarchy Frequency Mtrway 1 N/A Rads Strategic Rute 2 Once a mnth Main Distributr 3(a) Once a mnth Secndary Distributr 3(b) Once a mnth Lcal Rads 4a Once every 6 mnths Lcal Access Rads Urban 4b Once every 6 mnths Lcal Access Rads - Rural 4b Once a year Prestige Walking Rutes 1(a) Once a mnth Ftways Primary Walking Rutes 1 Once a mnth Secndary Walking Rutes 2 Once every 3 mnths Link Ftways 3 Once every 3 mnths Lcal Access Ftways 4 Once a year Cycle Lane A As cntiguus rad Cycle Rute Cycle Gap A As cntiguus rad Cycle Track B Once every 6 mnths Shared Cycle / Pedestrian B As cntiguus

7 Service Inspectin Frequency Other inspectin regimes Service Inspectins t identify all defects likely t cmprmise serviceability and sustainability shall be carried ut n the features listed in the table belw; such inspectins may be carried ut as part f respective general maintenance regimes fr each feature, if applicable. Nevertheless, the highway inspectr is expected t nte and reprt a ptential hazard fund during a service inspectin.

RESPONSE CATEGORIES Categry Defects Timescales Any safety defect identified n the Highway that exceeds the Safety Interventin Level(s) identified in sectin 2 f this guidance dcument shall be respnded t under ne f the fllwing three categries: Categry 1 Defects (High) - Attend, make safe r repair within 2 hurs Thse that require prmpt attentin because they represent an immediate and imminent hazard r because there is a risk f shrt term structural deteriratin. Categry 1 defects shuld be permanently crrected (if reasnably practicable), temprarily crrected r made safe at the time f inspectin. Permanent repairs shuld be carried ut within 28 days f defect identificatin. Categry 2 Defects (Medium) - Attend, make safe r repair within 5 days Thse which, fllwing an inspectin, are deemed nt t represent an immediate hazard r risk f shrt term structural deteriratin. Such defects may have safety implicatins, althugh f a far lesser significance than Categry 1 defects, but are mre likely t have serviceability r sustainability implicatins. These defects are nt required t be urgently rectified, yet shuld be permanently / temprary crrected r made safe within 5 days, r at the time f inspectin, if reasnably practicable. Permanent repairs shuld be carried ut within 28 days f defect identificatin. Categry 3 Defects (Lw) - Attend, make safe r repair within 28 days Thse which, fllwing a risk assessment, are deemed nt t represent an immediate hazard r risk f shrt term structural deteriratin. Such defects may have safety implicatins, althugh f a far lesser significance than Categry 1 defects, but are mre likely t have serviceability r sustainability implicatins. These defects are nt required t be urgently rectified, yet shuld be permanently / temprary crrected r made safe at the time f inspectin, if reasnably practicable. Permanent repairs shuld be carried ut within 28 days. Table 1: Risk Interventin Table Inspectin Frequency (Mnthly, 3 Mnthly, 6 Mnthly r Yearly) HIGH Cat 1 MEDIUM Cat 2 LOW Cat 3 Respnse (Cat 1) Attend, make safe r repair within 2 hurs Respnse (Cat 2) Attend, make safe r repair within 5 days Respnse (Cat 3) Attend, make safe r repair within 28 days Nte: All interventin level defects are t be actined and rectified within a maximum f 28 days. Observatins Thse that are nn-interventin defects and will be cllected by an inspectr t help infrm asset inventry and cnditin data and be used t plan lnger term priritisatin f future maintenance wrks.
