4 1.0 Introduction The National Roads Development Guide (NRDG) has been produced by the Society for Chief Officers of Transport in Scotland, supported by Transport Scotland and Scottish Government Planning and Architecture Division. The document follows the same principles introduced in Designing Streets with a change in national policy to move away from a standards based approach to one where designers, planners and roads engineers collaborate to develop a design led solution. The Councils Roads Development Technical Guidance has been devised to compliment the NRDG but takes into account local considerations which, on occasion, may be different than national guidance. This document highlights areas where Argyll and Bute Councils local Policies or Standards differ from the NRDG. Argyll and Bute Council area is diverse in nature and character and the Technical Guidance may not cover every situation. The Council reserves the right to vary requirements to suit particular local conditions as and when required or considered appropriate. Within Section 2 Supplementary Guidance to the NRDG, where sections of the NRDG are superseded entirely by guidance in this document this will be indicated by the term “Replacement Text”. Similarly, where sections of the NRDG have been added to this will be indicated by the term “Additional Text”. Developers working within Argyll and Bute Council area are required to use this document alongside the NRDG and cross-reference both documents. Developers may also require to refer to Designing Streets (DS) and the Design Manual for Roads and Bridges (DMRB). Where the NRDG refers to a design standard (e.g. the DMRB or British Standard) the most up to date version of the standard will be used. This document also provides further detail on the adoption of private roads (other than through the RCC process), variation of adoptable standards, development contributions through new developments and development of existing private roads.

5 2.0 Supplementary Guidance to the NRDG This section specifies the parts of the NRDG which are amended or replaced to meet the local requirements within Argyll and Bute Council area. This Scottish Government (SG) guidance is based on the June 2017 amended version. 2.1 NRDG Part 1 Paragraph 1.8: The Need for Consultation Following “Consultation should consider items such as, but not necessarily limit to the following:” add Additional Text • Geotechnical information – ground investigation, factual and interpretative reports. 2.2 NRDG Part 2 Paragraph 2.1.1: Statutory Consents (c) Work on the existing public road (Road Opening Permits): Additional Text Any work on or adjacent to existing public roads which are on or near structures shall be subject to prior consultation with Argyll and Bute Council Structures Section via structures@argyll-bute.gov.uk Paragraph 2.1.4: Design Guidance and Adoption Standards Following “6 or more individual dwellings should normally be served by a “road” which will require Construction Consent and the submission of a road bond in a residential area.” add Additional Text Refer to Section 5.0 “Small Housing Developments (for use for 6 to 10 dwellings)” or Section 6.0 “Variation on Road Standards for Specific Islands” of this document for details regarding a variable adoptable standard for developments of 6 – 10 dwellings. A Construction Consent and the submission of a Road Bond may still be required. Note, Housing Associations are exempt from the provision of Road Bonds.

6 Paragraph 2.2.6: Roads and Lane Widths (a) Junction Types and Arrangements Additional Text Site specific visibility standard sightline distances within Argyll & Bute are detailed within section 3.1 Road Design, 3.1.1 (c) Junctions of this document (d) Integrated Parking Following “In addition, the evolution of car design has resulted in increased car sizes over recent years, rendering much of the previous car parking space guidance outdated and no longer fit for purpose. Refer to Parking Standards in Part 3” add Additional Text It is recognised that integral parking provision within residential dwellings may be converted for other uses (Permitted development). Therefore this parking arrangement shall not be counted within the required parking standards. Refer to Table A8 Car Parking Standards of this document for the parking provision within Argyll and Bute Council area. Paragraph 2.2.7: Street Detail (a) Drainage and Sustainable Urban Drainage Systems (SUDS) Additional Text SUDS schemes must comply with current SEPA guidance and approval process. (b) Flood Risk Management Additional Text Flood management must be in accordance with current guidance and the Councils flood “policy” (c) Utilities Additional Text Where the proposed new road is a prospective adopted road, provision for (public utilities) services must be made. If services are not being installed during the road construction phase then ducting appropriate to the scale of the development must be provided. In addition to this, where a system of street lighting is not being installed as part of the initial development ducting must be laid to allow the provision of lighting at a future date. Note, ducts must include draw-rope at installation.

7 Paragraph 2.3.8: Adoption of Sustainable Urban Drainage Systems (SUDS) for Roads Additional Text Where SUDS contains road surface drainage only and is contained within the road corridor or servitude rights have been granted for areas outwith the road corridor, the roads authority will adopt the scheme. The Council, as roads authority, may enter into agreement with Scottish Water for shared systems. Paragraph 2.3.10: Structures Agreements Additional Text Any agreement involving a structure shall be subject to the Technical Approval Process as outlined in Paragraph 3.8 of this document. Paragraph 2.3.11: Roads Bonds Additional Text For any prospective adopted road a road bond will be required. The road bond will be calculated based on the rates in Appendix 1; rates may be subject to inflation. Paragraph 2.4: Applying for Construction Consent Additional Text The Councils published Fees & Charges (link below) provides detail of the charges for the processing of RCCs. Charges may be subject to annual increases under the Councils budget setting processes. https://www.argyll-bute.gov.uk/council-and-government/council-fees-and-charges Paragraph 2.4.9: Construction Consent Forms Additional Text The Council’s Construction Consent Forms are contained in Appendix 2 of this Technical Guidance document. Submissions should be made to the local Traffic & Development Officer at the addresses listed in Appendix 3. The Argyll and Bute Council Construction Consent Forms are contained in Appendix 2. Permission is hereby granted for this these forms to the photocopied.

8 Paragraph 2.4.12: Inspection Procedures during Construction (a) Notice of Commencement (b) Sub-paragraph (3) Notice of Operations Replacement Text The developer or his contractor must give the Local Roads Authority representative a minimum 3 working days’ notice (excluding weekends and public holidays), unless otherwise agreed with the Roads Authority, of: (a) Completion of formation; (b) Commencement of each pavement layer to the carriageways, cycle track, footways and footpaths; (c) Each concrete pour (including blinding) and commencement of steel fixing where reinforced concrete is used; (d) Striking of formwork; (e) Setting out of road lighting plant positions, backfilling of cable trenches and painting of lighting columns; (f) Placing and testing of drainage systems. It should be noted that these are minimum requirements and that, in certain cases, the developer may be required to notify the Local Roads Authority’s representative of additional construction stages. Developers should also note that failure to notify the representative as above can result in covered over work to be exposed for inspection at the developer’s expense to ensure that the construction complies with the Construction Consent. Finally, failure to notify can result in delays to adoption or potentially seriously compromise the adoption process. Sub-paragraph (4) – Charges for Inspection & Testing Additional Text The Councils published Fees & Charges (link below) provides detail of the charges for RCC Inspections. Charges are calculated pro rata based on the Road Bond Value. Charges may be subject to annual increases under the Councils budget setting processes. Inspections fees shall be paid in full prior to commencement of works. https://www.argyll-bute.gov.uk/council-and-government/council-fees-and-charges

9 2.3 NRDG Part 3 Paragraph 3.1.1: Junctions Following “The range of junction types and arrangements are discussed in Designing Streets (page 36). This section details required junction criteria to enable a design to function correctly in relation to its user demands.” Additional Text Note that for all junctions on high speed roads (40mph or above), the guidance in Designing Streets is not appropriate and the DMRB must be referred to for guidance. Paragraph 3.1.1: Junctions (C) Visibility Splay Area Replacement and Additional Text “Stopping sight distances and visibility requirements are detailed in Designing Street (pages 33-35).” Replace the table with the following tables and add the following text: Table A1 – Lightly Trafficked Roads Vehicle Speed (mph) 60 50 45 40 35 30 20 Y distance 136 103 84 75 53 42 25 For Strategic Routes and other routes carrying traffic volumes greater than 3000 Vehicles Per Day (VPD), use figures in Table A2. The list of Strategic routes and higher traffic routes is detailed in Appendix 4. Table A2 – Strategic and Heavily Trafficked Routes Vehicle Speed (mph) 60 50 45 40 35 30 20 Y distance 160 120 95 75 53 42 25
Page 10
10 Traffic volumes are in vehicles per day (VPD) and refer to the total combined flow in both directions. Where actual speed falls between the given values the y – distance may be interpolated by the Roads Authority. The ‘x’ – distance will normally be taken as 2.4m. Where considered appropriate by the Roads Authority the following x-distances may be used: • 4.5 metres for flows up to 3,000 v.p.d. • 9.0 metre for flows in excess of 3,000 v.p.d. The visibility envelope (vertical plane) shall be taken as1.05m (“driver’s eye”) to 0.6m above the carriageway. The “driver’s eye” may be increased to 2m for lorry drivers. The traffic speed to be used is the mean speed on the public road. This will either be measured or estimated by the Roads Authority. Developers should note that they must either own or obtain control of the land contained within a visibility splay, except when it is already controlled by the Council as part of the public road corridor. Control must be obtained through an agreement, in accordance with Section 75 of the Town and Country Planning (Scotland) Act 1997 to ensure that the visibility splay remains free of obstruction in perpetuity. Paragraph 3.1.2: Private Access (a) Access Criteria Additional Text For further detail, including sightline requirements, please refer to Section 4: Small Housing Developments (for use for 1 to 5 dwellings). (C) Individual Dwellings Additional Text It should be noted that where a vehicular dropped footway crossing is required, the footway level must be re-profiled over its full width, or in the case of very wide footways over a minimum width of 2.0m. This prevents an excessively steep lateral gradient and slipping risk. See Figures A1a, A1b and A1c below. Note, where the dropped kerbs are also being used as a pedestrian crossing point the upstand shall be reduced to no more than 0mm.

14 Notes to Tables A3 & A4 1. Verge, footways or service strips to be 2m minimum on both sides of the carriageway. 2. Roads intended for use by buses are subject to a maximum gradient of 6% 3. Roads constructed with modular surfacing are subject to a minimum gradient of 1.25% and a maximum of 5%. 4. In a rural setting private accesses should not be constructed within 90 metres of a road junction or within 25 metres of an existing private access. 5. Speed limits may be amended locally dependent on traffic flows and mean speeds. (D) Gradients and Crossfalls Under “Maximum Gradients” Additional Gradients Maximum gradients should comply with Tables A3 and A4. Any departure from this standard must be agreed in writing by the Roads Authority. In no circumstances shall a gradient be greater than 10%. Under “Junctions”: Replacement The maximum gradient rising or falling on the final approach of a minor roads at the junction shall be limited to 5% for at least 12 metres from the interface with the major road. Under “Vertical Curve Length” Replacement The length of a vertical curve is based on the difference in gradient multiplied by the factor K. Refer to Tables A3 & A4 for the appropriate K value. (G) Provision for Public Transport Under “Bus Stop Provision” Following “Good public transport provision should be available at the initial phase of any new development, either by linking to existing networks or by establishing new routes and should therefore be discussed with local transport operators and the Local Authority’s Transportation manager at an early stage.” Additional Text In rural areas it may be necessary for the developer to provide hard standing areas to support bus pick up/drop off points. Consultation with the local Traffic & Development Officer at an early stage is recommended.

15 Additional Text (h) Industrial Estates General Principles 1. Industrial developments shall be served by a road that requires Road Construction Consents. Industrial access roads shall be designed to incorporate HGV and Bus traffic. The applicant should be aware that the Roads Authority may require some form of financial security (normally a road bond) to be provided in relation to any prospective adoptable industrial estate roads; or where significant improvements to the external public road network are being carried out to make the development feasible or acceptable to the Roads Authority. 2. The Road Authority will not normally adopt industrial estate roads. Where the road is to be adopted this will normally be restricted to the main distributor road and any turning areas. Service roads will not be considered for adoption. Road Construction Consents (RCC) shall follow the normal process as detailed in the NRDG, Section 2.4 Applying for Construction Consent. 3. An industrial estate road provides frontage or service access to industrial and commercial premises. 4. Where service bays or areas associated with industrial or commercial developments are contiguous with the public road, agreement must be reached with the Roads Authority as to whether they are to be adopted or not. There must be clear markings delineating private areas; these should be of permanent form and require regular maintenance, i.e. not be road markings. Design Requirements 1. The alignment of an Industrial Estate Road will largely depend on its length but a formal design speed is still considered appropriate for assessing curve radii and visibility. The normal maximum speed limit will be 30mph. If the proposed estate road will form a part of a bus route then consideration will be given to speed reductions. Note that a 30mph speed limit equates to a 60kph design speed. 2. The carriageway should be a minimum width of 7.3 metres, but it may be acceptable to reduce this to 6.0 metres where commercial vehicle activity is likely to be limited, for example a small unit development or where there is one-way working. Any variance of carriageway widths are subject to approval by the Roads Authority.
Page 16
16 3. A minimum 2 metre wide footway shall be provided on both sides of the road, which will be increased to at least 3.0 metres minimum if shared footway/cycleway are provided. The footway or footway/cycleway shall be separate from the carriageway by a 2 metre verge preferably. Where the verge is located at the rear of the footway or footway/cycleway then a separation strip of no less than 0.6 metre width shall be required for a segregation strip. The segregation strip shall be formed of such materials to clearly show delineation from footway or footway/cycleway area. Localised widening of footway/cycleway may be required in the vicinity of bus stops. 4. Depending on levels of movements and also any surrounding pedestrian/cycle network, there may be a requirement for pedestrian crossing facilities. Bus services (new or enhancement) and public transport infrastructure may also be required. 5. Where direct frontage access is permitted on to the adopted road network, turning facilities in-curtilage shall be provided within the development. This is to ensure vehicles enter and exit the site in forward gear and no reversing is carried out within the adopted road network. 6. Carriageway design shall be to DMRB. Rigid pavement construction will not normally be accepted although this may be varied for individual accesses which will remain private. 7. Industrial Estate Roads and Access Roads shall be designed to remove reversing manoeuvres within the road network, including when exiting or entering the road network from properties. This may require industrial estate roads to be designed as through routes (loops) or with a turning area at the end of a road. Example of turning layouts can be found in Figure A3. Industrial estate roads should be designed to cater for 15.5 metre articulated vehicles or 11 metre rigid vehicles as a minimum. Swept path analysis will be required to prove that proposed layouts work. 8. Notwithstanding the above paragraphs, it is acknowledged that each industrial estate may require consideration on its own merits.

19 Parking Requirements 1. On street parking will not normally be acceptable. Off-street parking shall be designed in such a way as to prevent queues forming on the adopted road network. 2. Parking for each site must take into account the following types of parking: a. Operational – for service vehicles and staff parking who require to use their vehicle as part of their day to day activities. b. Commuter parking – for staff who drive to and from work. c. Visitor parking – for customer and other visitors. 3. Parking areas may be required to include landscaping and other measures to mitigate against vast open, unattractive areas. This will be advised by planning guidance. 4. Parking areas will, however, create additional surface water and this will need to comply with SUDS and other water management regulation. Surface water generated out with the public road network will not be permitted to discharge into public road surface water drainage system. 5. Suitable segregation between vehicles and pedestrians must be maintained in parking areas. Table A7 - Industrial Units Parking Requirements Reference to m2 is to gross floor area A&B Roads minimum** Wholesale Warehouses 1.1 Space per 100m2 Storage or distribution 4 spaces per 100m2 General Industrial 2 spaces per 100m2 Disabled parking (retail / leisure / recreation) 3 spaces or 6% up to 200 space car park or 4 spaces or 4% in car parks with greater than 200 spaces Disabled parking (places of employment) 1 space per disabled employee plus 2 spaces or 5% (whichever is greater in car parks with up to 200 spaces; or 6 spaces plus 2% in car parks over 200 spaces.

20 Additional Text (i) Housing Courts (serve up to 20 dwellings) 1. A Housing Court is similar in concept to a car park with a shared surface finish for joint pedestrian and vehicular use. The associated dwellings are located around the court. A Housing Court will not be adopted by the Roads Authority. 2. The Court will provide parking spaces relative to the number of dwellings, up to a maximum of 20 dwellings, and no point within the court should be more than 40 metres from the access point. 3. The access road to a Housing Court must be a minimum of 5.5 metres wide over the first 10 metres. A strong physical definition must be provided to indicate the nature of the layout to the driver and that it is a private area. 4. Where a Housing Court is provided at the end of a Housing Road cul-de-sac, a separate turning head must be provided to ensure that drivers do not need to enter the Court in order to turn. Figure N1: Indicative housing court layout 5. Provision must be made within a Housing Court for servicing where there is a servicing provision, including postal deliveries. The service vehicle must be able to enter and leave in a forward gear at all times. 6. Refuse collection must be arranged so that communal or centralised waste collection is provided adjacent to the public road. Underground refuse storage facilities may be considered as appropriate.
Page 21
21 7. Statutory Undertakers should be encouraged to use any footways or landscaped areas outwith the Housing Court, otherwise a wayleave agreement will have to be reached with the house owners to allow access to apparatus. 8. As these Housing Courts will not be adopted by the roads authority, all lighting must be provided and maintained by the developer. Paragraph 3.1.4: Pedestrians and Cyclists (B) Pedestrian Provision Under “Width of New Footways Additional Text The minimum acceptable footway width shall be no less than 2 metres in normal circumstances. Where the local environment is constrained such that a 2 metre footway is not feasible, the roads authority may consider a reduction in width to 1.5 metres. This will be subject to local conditions including, for example, vehicular traffic volume, pedestrian volume and the hierarchy of road. Under “Obstacle in Pedestrian Desire Line” Additional Text Relaxations may be permitted depending upon local conditions. Where the obstacle is a free standing sign (e.g. A-Board, Barrel sign etc.) the minimum footway widths must be maintained in accordance with the Councils Advertising & Signage Policy and its associated application processes. Under “Steps or Ramps on Footway” Following “Steps should have 0.3 metre permanently nonslip treads and a minimum clear width of 1.4 metres” Additional Text Steps shall be formed with a material approved by the Roads Authority. Under “Disabled Access to Buildings” Additional Text Disabled access to buildings will not form part of the adopted road.
Page 22
22 Paragraph 3.15: Servicing (G) Refuse Collection Additional Text The Councils preferred refuse collection model is through communal or centralised waste collection where appropriate. Consideration may also be given underground refuse storage facilities. Bin collection points or facilities must not be more than 30 metres from the relevant residence. The bin storage facilities must be within 10 metres of the proposed vehicle collection. Where the development is mixed (e.g. commercial and residential) separate waste facilities must be provided. Reversing manoeuvres must be designed out as far as reasonably practicable. Where this cannot be achieved then reversing distance must be kept to a maximum of 10 metres. Paragraph 3.1.6: Statutory Undertaker Services (K) Planting and Service Strips Replacement Text No structures, walls, fences, or planting (other than low maintenance fauna as agreed with the Roads Authority) are permitted to be located within the service strips. In general the Roads Authority will not permit any planting within the proposed roads corridor and will not adopt any maintenance or ownership of planting (other than grass verges). This stipulation may be waived if the planting forms part of a SUDS design, however, note that the adopted road corridor shall not be artificially widened to accommodate SUDS. In addition to this, the Roads Authority will not normally adopt SUDS or other drainage installed in private land. If cases where the SUDS or other drainage schemes in private land are adopted by the local authority, these must provide safe vehicular access for maintenance and appropriate servitude rights in perpetuity. (L) Road Opening Consultation and Consents Following “…must be obtained from the Road Authority before any excavation is undertaken in a public road” Additional Text Windfarm developers in particular should ensure that discussions regarding national grid connections and cable routing are undertaken early in the design process and
Page 23
23 are ideally run in parallel with the Planning and Road Construction Consent process. (M) Provision of EV Charger facilities Additional Text Ducting for future provision of EV chargers or charging shall be provided, where appropriate, to the scale of the development and to the satisfaction of the Roads Authority. Paragraph 3.1.7: Rural Areas (C) Road Widths Under “Developing on Existing Roads” Following “Note this requires statutory consents such as a Section 56 Roads (Scotland) Act 1984." Additional Text It should be noted that widening or increasing traffic volumes on existing roads can present significant issues if structures are affected, in such cases the application shall be the subject to the Technical Approval process as outlined in Section 3.8 of this document. Under “Speed Visibility Relationship” Replacement Text Replace Tables 8 & 9 in the NRDG with Tables A1 & A2 contained in this document. Paragraph 3.1.9: Additional Considerations After “(d) Fire Fighting”, add Additional Text (e) Windows, doors and gates Where the building line is at or near the road corridor (verge, footway or carriageway etc.) any windows and doors facing the road must open inwards. Gates on the boundary of the public road should open away from the road corridor. (f) Carriageway Edge Restraint In general, it is expected that developments within urban areas will include carriageway edge restraint (normally pre-cast concrete kerbing), however; rural developments, including any improvements to the existing public road are, are not
Page 24
24 always subject to the same requirements. This section sets out the reasons for utilising edge restraint in a rural environment: • Edge restraint supports the carriageway structure and prevents edge deformation and ”spreading” • The use of kerbing, or other agreed measures, acts as a demarcation between vehicular traffic and pedestrians of rural footways or verges; • Where an upstand is provided the kerb acts as a check to prevent vehicles leaving the carriageway; • Again, using an upstand allows a channel to be formed at the interface between the kerb and carriageway edge which allows surface water to be effectively drained. Paragraph 3.4.1: Geotechnical Considerations (b) Supporting Technical Documentation Following “Where it is proposed to locate a road over land previously used for industrial purposes or waste disposal, it is essential that chemical analysis and gas monitoring information is submitted in addition to standard laboratory testing to BS 5930: 1999 and BS 1377: 1990.” Additional Text Current technical standards for ground investigation and testing are to be used. Following (g) CBR Additional Text (h) Slope Stability Where there are soil slopes within influencing distance above or below the roads, footpaths or verge slope stability analyses will be required. (i) Embankment and Fill Embankments and areas of up fill may require to be monitored over a period of time to demonstrate that settlement is complete before adoption. Paragraph 3.4.4: Carriageway Construction (a) Pavements Replacement Text Carriageway Pavement design should be in accordance with the Design Manual for Roads and Bridges. This requires details of the ground bearing capacity and the traffic type and volumes to be identified to arrive at a suitable load spreading pavement. A composite construction may be acceptable providing agreement with the road authority is sought in advance.
Page 25
25 BS 7533 for block paving and the additional qualifications and exceptions listed here. Capping Layer Where the CBR value is less or equal to 5%, a capping layer is required as per Figure 29. NB: The design California Bearing Ratio (CBR) should be obtained either by testing or by measurement of the plasticity index of the subgrade material. In the case of CBR testing, the method described in the laboratory test in accordance with BS 1377-4:1990, clause 7 should be used and is only relevant in natural soils and cannot be used for pavement design in fill materials. By their nature fills are random and highly variable in density and CBR testing in them only assesses the quality of the material at the locus of the test. Therefore for pavement construction on fill materials, unless the fill material is equivalent to or better than the specified capping material, a full capping layer is required. Frost Susceptibility It is possible for roads designed to have a total bituminous thickness of 170 mm and, with a CBR value < or + to 2%, a 150 mm sub-base and 600 capping layer. In such circumstances the upper 130 mm of the capping layer should be non frost- susceptible. In practical terms this effectively means that the sub-base becomes 280 mm with a capping layer of 470 mm. For a 2%<CBR<or+5% where the total bituminous thickness and sub-base thickness together are less than 450 mm the same principle applies (ie the sub-base is increased to achieve 450 mm of non frost susceptible material and the capping layer can be correspondingly reduced). This need not be done if the capping layer is non frost-susceptible. Increased Capping Layer Thickness Although Table 10.1 gives various thicknesses of capping layer dependent upon CBR, where CBR is significantly below 2%, these thicknesses may require to be
Page 26
26 increased dependent upon site and weather conditions prevailing at the time of construction. This requirement will be accompanied by an additional CC8 Engineers report to certify the design. Additional material may require to be removed and replaced by more suitable material. Although the new material may be of good quality, the subgrade shall be assumed to be equivalent to one of a CBR just under 2% and requiring 600 mm of capping layer. The developer should consult the Roads Authority for advice in these circumstances. Formation on Rock Where the formation is on rock, the granular sub-base will act as a 150 mm depth regulating layer. Carriageway Construction Where suitable technical facilities exist it is recommended that the specific circumstances of each site are catered for by designing the road in accordance with the criteria stipulated above, subject to a minimum construction as required to carry 0.5 Million Standard Axles (MSA), for all roads. In this circumstance it will be necessary to complete and return form CC8 ‘Carriageway Design Certificate (d) Clay, Natural Stone or Block Paving Pavements Additional Text Unless otherwise agreed with the Roads Authority, adopted or prospective adopted carriageways and shared surfaces shall be bituminous material. Where the Roads Authority considers that block paving may be appropriate the following restrictions will apply: i. In carriageways or shared surfaces Clay Pavers shall not be permitted for use. ii. Concrete Block Pavers may be considered for use in these areas but must have a minimum depth of 100mm. iii. Permeable block pavers will not be accepted by the Roads Authority. iv. The bedding layer must be drained but shall not be used for storage of surface water. v. The use of block paving is restricted to development with a maximum of 20 dwellings. vi. The use of block paving will also take into consideration the long term maintenance liability in recognition of declining roads maintenance budgets. Paragraph 3.4:7: Kerbs and Edging (a) Materials / Construction Replacement Text All carriageways, footways and footpaths should be provided with precast concrete kerb or edging. Alternatively and with the approval of Argyll & Bute Council natural stone kerbs may be acceptable.
Page 27
27 On conventional roads, kerbs should be set 125mm above finished carriageway level at the channel, except at pedestrian and vehicular crossings where this dimension is reduced to 0mm maximum and 10mm maximum respectively. Edging at heel of footways should be 50mm upstand whereas footpaths it should be set flush with the walking surface. On shared surfaces, an upstand of 20mm, with a suitably contrasted colour, should normally be provided, except at junctions with footpaths and private accesses where kerbs should be set at 10mm upstand for vehicles or 0mm for pedestrians A delineation kerbline at the rear of the verge may be required to identify the extent of the adopted road corridor. (b) Remote Areas (not contiguous with the carriageway) Replacement Text In remote areas, and with the agreement of Argyll & Bute Council, cycleways may be constructed without kerb edgings, where the sub base is laid 500mm wider than the surfacing to provide shoulders. Paragraph 3.4:8: Accesses Replacement (a) Driveways Vehicular access crossings of footways for individual dwellings should comply with Figure A1a of this document and be constructed as per NRDG Paragraph 3.4.6. Future maintenance requirements preclude the use of slab footway construction for vehicle crossings. Replacement (b) Other Access Details Where vehicular access, other than individual dwellings, is taken then Figures A2a and A2b shall be used and accesses shall be constructed in bituminous material unless otherwise agreed with the Roads Authority. Note: i. Subject to agreement by the Roads Authority, an absolute minimum access width may be reduced to 3.6 metres. Wider accesses may be required dependent on function and environment. ii. Radii at the interface with the public road may be required to be reduced to assist in controlling vehicle speed. (c) Pedestrian Access/Crossings Replace paragraph “Figure 32 details the requirement for dropped kerbs where pedestrian routes cross the carriageway from adjacent footways, e.g. at T-junctions and pelican crossings. Pedestrian crossings of a carriageway with an adjacent grass verge should comply with Figure 31 except that the dropped kerb should be
Page 28
28 set flush, or not more than 6mm upstand, with the carriageway and extend for a minimum length of 1.8 metres.”, with: Replacement Text Figure A4 details the requirement for dropped kerbs where pedestrian routes cross the carriageway from adjacent footways. Pedestrian crossings of a carriageway with an adjacent grass verge should comply with Figure A1c except that the dropped kerb should be set at no greater than a 5mm upstand with the carriageway and extend for a minimum length of 1.8 metres. Paragraph 3.4:9: Road Drainage and SUDS (a) Specification Best Management Practices Sustainable Urban Drainage Systems Following “The final design of the drainage system must be to the satisfaction and meet the requirements of the local Roads Authority, the appropriate Water Authority and Scottish Environmental Protection Agency (SEPA) Additional Text Contact Argyll & Bute Council’s Flood Risk Management section who will provide on request a copy of the Council’s Sustainable Drainage Systems (SUDS) Design Criteria Guidance Note.

(h) Chambers Replacement Chambers should be constructed in accordance with Clause 507 of the Specification. Manhole covers and frames shall be non-rock and comply with BS EN 124 and be Class D400 (minimum clear opening 600 mm dia or equivalent, minimum depth of frame 100 mm) except in non-contiguous car parks or verges where the use of Class B125 (minimum clear opening 600 mm dia or equivalent, minimum depth of frame 100 mm) may be permissible. Paragraph 3.4:10: Landscape Treatment (a) General Issues Additional Text It should be noted that Argyll & Bute Council will generally not adopt landscaped areas within development sites. These should be subject to formal factoring arrangements. We will however, adopt grassed service strips and landscaping associated with A&B Council’s adopted SUDS features. Paragraph 3.4.11 Lighting Design (c) Network Manager Additional Text A system of street lighting may not be required in every setting, for example with rural locations. Prior to commencing lighting design, early engagement is encouraged with the local Traffic & Development Officers to ascertain the general requirements or otherwise. Paragraph 3.5: Parking Considerations Additional Text Argyll and Bute Council has a maximum parking standard, as outlined in the LDP, however, given the need to take account of parking issues in rural or semi-rural areas it also has minimum parking standards which are detailed in Table A8 below. 1. Where a proposed development is not specified within Table A8, the Roads Authority will select the nearest type of land use as a basis for assessing parking requirements. 2. Each car parking space must measure no less than 2.5 metres by 5 metres.
Page 32
32 3. Parking layouts must include circulation aisles with a minimum width of 6 metres. 4. Assessments for the required number of spaces, based on Table A8 below, must be rounded up to the nearest whole number. 5. Where the Roads Authority considers it appropriate there may be a requirement to provide suitable cycle storage facilities. 6. Within town centres, parking requirements may be reduced where there is good public transport provision.

Free standing garages of at least 6m x 3m within 30m of the dwelling can be counted unless there is a site specific reason not to. Car ports will generally be counted as spaces. Paragraph 3.7: Parking Standards for Use Classes Replacement Text Argyll and Bute Councils parking standards are detailed in para 3.5 and Table A8 of this document. Any variations to the parking standards must be evidence based and subject to approval. Paragraph 3.8: Structures Technical Approval Replacement Text Structures Technical Approval Requirements All structural design and assessment shall be subject to the Technical Approval procedures outlined in CG300; Technical approval of highway structures of the DMRB. Argyll and Bute Council are the Technical Approval Authority (TAA) for all road structures and pedestrian footbridges that are the responsibility of Argyll and Bute Council (independent of maintenance responsibility). Whilst the scope of CG300 and CD622 fully apply, Structures requiring technical approval are summarised below: • All road retaining structures with an effective retained height of greater than or equal to 1.0m require technical approval in accordance with CG300.
Page 36
36 • All culverts and bridges with a clear span or internal diameter greater than 0.9 m in diameter require technical approval in accordance with CG300. • Any geotechnical works (i.e. embankments) “which may pose a risk to the general public, Argyll and Bute Council and/or Argyll and Bute Council’s asset” require Technical Approval in accordance with CD622. It is highly recommended that early involvement with Argyll and Bute Council’s Structures team is established for all schemes involving the above at structures@argyll-bute.gov.uk

37 3.0 Development Contributions 3.1There may be applications where a development proposal is deemed acceptable but is unable to proceed due to either deficiencies in roads infrastructure or that the development may impact roads infrastructure (including impact on traffic flow, public transport etc.) in the wider context of the area. In such cases, the Council, as Roads Authority, may require the developer to either carry out improvement works as required or, by agreement, to provide cash sums to allow the Council to carry out the works at its discretion. 3.2 Further to paragraph 3.1, the Roads Authority may request that sums are commuted for schemes which have a potential high cost future maintenance, for example complex SUDS, remote cycle paths or schemes with block paving as the running surface of the carriageway. Typically commuted sums would take into consideration the estimated maintenance costs for an appropriate period of time post-adoption to ensure such matters are appropriately addressed. 3.3 The main legislation where agreements may be made are governed by the Town and Country Planning Act 1997, as amended, Section 75, the Local Government (Scotland) Act 1973 Section 69 and the Roads (Scotland) Act 1984 Section 48. There are other legislation and regulations which may be used if considered appropriate. 3.4 The Planning (Scotland) Act 2019 may provide further powers under s54 to create an infrastructure levy through subsequent Regulations. This matter will require to be considered as any Regulations are introduced. 3.5 While s75 agreements would be related to any grant of Planning Permission; s69 would require to be settled prior to the release of Planning Permission. Section 96 agreements may form part of the RCC process, particularly if the risk is linked to the construction phase, but should be highlighted within the Roads comments during the planning application process. 3.6 Any Section 75 agreements will require to accord with the advice set out in the Scottish Government Circular 3/2012 - Planning Obligations and Good Neighbour Agreements. 3.7 A typical legal agreement will include articles including but limited to the following: ▪ the parties to the agreement; e.g. the Council, Applicant, etc.; ▪ the development to which the Legal Agreement relates; ▪ the contributions requiring to be paid; ▪ when the contribution is required to be paid i.e. settlement trigger point; ▪ whether the contribution should be paid in one or multiple instalments; ▪ the consequences should the contribution not be settled when agreed; ▪ the purpose for which the contribution will be spent or applied by ABC; ▪ the deadline by which the contribution will be spent or applied by ABC; ▪ the terms of contribution return if the scheme is withdrawn

38 4.0 Small Housing Developments (for use for 1 to 5 dwellings) Introduction 4.1 This section provides guidance for developers seeking planning permission for small residential developments of 1 to 5 dwellings within the Argyll and Bute Council area. This includes that part of Argyll & Bute within the Loch Lomond and The Trossachs National Park. 4.2 Compliance with roads requirements and standards is only part of the planning process and in no way guarantees that a development will be granted planning approval. 4.3 The requirements laid out in this document apply to private accesses joining the public road. Private accesses are also referred to as private driveways. 4.4 Any retaining structures, adjacent to the public road, to be constructed as part of the development, must be designed in accordance with current good practice. A design certificate will be required. 4.5 Further consultation or information is available by contacting Network & Standards Officers, contact details are listed in Appendix 3 of this Technical Guidance document. 4.6 Where a proposed development takes access to the public road network onto a Trunk Road, contact should be made with the Trunk Roads Authority. Visibility Requirements 4.7 The provision of a new or improved access from a private access onto a public road must include adequate visibility. This is essential to enable drivers emerging from the private access to see and be seen by drivers proceeding along the public road. To achieve this, unobstructed visibility is needed within the shaded areas in Figures A10, A11, A12 & A13. These requirements are referred to as visibility splays and are defined by: the ‘y’ dimension measured along the near edge of the public road from the centre line of the private access, to both left and right; and the ‘x’ dimension measured from the edge of the public road along the centre line of the proposed access For clarity, the edge of the public road will be considered as the carriageway edge in most circumstances; the exception to this is where access is taken from a Strategic Road (as detailed in Appendix 4) where the edge of the public road shall be taken as the back of footway or verge (i.e. the curtilage of the property). The Roads Authority may use discretion where it considers it appropriate.
Page 39
39 Figure A10: Visibility Splays - Visibility is required over the shaded area shown in Figure A10 4.8 Where the access is on the outside of a bend, an additional area will be necessary to provide splays which are tangential to the road edge as shown on Figure A11. When accesses are located on bends a check must be made to ensure vehicle divers have adequate forward visibility, i.e. they are able to see approaching traffic on the public road to allow them to complete their manoeuvre safely. (Figure A13) Figure A11: Visibility Splays for Accesses on the Outside of Bends
Page 40
40 Figure A12: Visibility Splays for Accesses on Inside of Bends The normal requirements for visibility distances are set out below. X – distance (m) The ‘x’ – distance will normally be taken as 2.4m. Where considered appropriate by the Roads Authority, the following x-distances may be used: • 4.5 metres for flows up to 3,000 v.p.d. • 9.0 metre for flows in excess of 3,000 v.p.d. Y – distance (m) and Forward Sight Distance (m) The ‘y’ distance is based on a) the speed of the traffic on the public road, to ensure drivers can react in time to avoid a collision and b) the expected traffic flow on the public road, to avoid the need for traffic on the public road to slow down or stop in order to avoid a collision. The visibility envelope (vertical plane) shall be taken as1.05m (“driver’s eye”) to 0.6m above the carriageway. The “driver’s eye” may be increased to 2m for lorry drivers. For quiet roads, Table A1 should be used (repeated below for ease). For Strategic Routes and other routes carrying traffic volumes greater than 3000 vehicles per day (vpd), use Table A2 (repeated below for ease). See Appendix 4 for a list of Strategic Routes and those carrying higher volumes of traffic.
Page 41
41 Table A1 – Lightly Trafficked Roads Vehicle Speed (mph) 60 50 45 40 35 30 20 Y distance 136 103 84 75 53 42 25 Table A2 – Strategic and Heavily Trafficked Routes Vehicle Speed (mph) 60 50 45 40 35 30 20 Y distance 160 120 95 75 53 42 25 For Strategic Routes and other routes carrying traffic volumes greater than 3000 vpd, use figures in Table A2. Refer to Appendix 4 or a list of Strategic routes and higher traffic routes. 4.9 Traffic volumes are in vehicles per day (vpd) and refer to the total combined flow in both directions. 4.10 Where actual speed falls between the given values the y – distance may be interpolated by the Roads Authority. 4.11 The traffic speed to be used is the mean speed on the public road. This will be measured or estimated by the Roads Authority. 4.12 Applicants should note that they must either own or obtain control of the land contained within a visibility splay, except when it is already controlled by the Council as part of the public road corridor. Control must be obtained through an agreement, in accordance with Sect 75 of the Town and Country Planning (Scotland) Act 1997, to ensure that the visibility splay remains free of obstruction in perpetuity. Visibility on the Public Road 4.13 It will be necessary to check that forward visibility is not obscured. Vehicle drivers waiting to turn into private access should be able to see the road is clear before commencing the turning manoeuvre. Equally, following traffic must be able to see vehicles waiting to make a turning manoeuvre.
Page 42
42 Figure A13: Forward Visibility Splays 4.14 The area within visibility splays (both those beside the private road and those required for forward visibility) must be cleared of all obstructions to view, higher than 1050mm above the level of the adjacent carriageway. Minor departures from this requirement, such as the retention of a single slender pole or column, may be permitted as long as visibility is not materially affected. Visibility splays must be kept clear in perpetuity. 4.15 Visibility in a vertical plane must normally be provided from a driver’s eye height of 1.05 metre to an object height of 0.6 metre. For accesses taken from Strategic Routes the driver’s eye height of 1.05 metres to an object height of 0.26 metres above the carriageway may be used; Figure A14 below is provided for clarity. Figure A14 – envelope of visibility 4.16 The Roads Authority will not introduce or extend a speed limit simply to facilitate a new private access. Location of Accesses 4.17 The access should usually be located a minimum of 25 metres away from the nearest adjacent junction. However, a relaxation may be permitted depending on the local conditions. 4.18 Accesses for adjacent houses should generally be shared to avoid proliferation of accesses.
Page 43
43 Drainage 4.19 Drainage shall be provided where necessary to prevent water from the access flowing onto the public road. Similarly, when an access is being constructed the existing road drainage must either be maintained or an effective alternative provided, to the satisfaction of the Roads Authority. Layout of Access for Single or Paired Dwellings 4.20 Where the frontage of a development site consists of a footway parallel to the public road, accesses will be formed by lowering the kerbs and footway, in accordance with standard detail SD 08/ 005 Rev. B (see Appendix 5). 4.21 Where the speed limit is greater than 30 mph, any entrance gates should usually be sited at least 6 metres from the edge of the carriageway to allow an entering vehicle to stop clear of the carriageway when the gates are closed. Gates must be hung so that they do not open towards the carriageway. 4.22 Where the speed limit is 30mph or less, the gate must be hung so that they cannot open towards the footway, verge or carriageway. 4.23 The gradient of the access should not normally exceed 5% over the first 5 metres from the edge of the public road. The remainder of the access should not exceed a gradient of 12.5% .Steeper accesses can lead to problems with parking, traction in winter and control of drainage. 4.24 Where the access crosses a footway, it is important to have intervisibility between drivers and pedestrians, particularly small children. In these circumstances there should normally be visibility between a driver’s viewpoint (1.05m above carriageway level) 2.4 metres back in to the access to an object 0.6 metre above the footway and 2.4m on either side, along the back of the footway. Access Construction 4.25 The access shall be surfaced with a bituminous material for the first 5 metres from the edge of the carriageway or back of any local road widening; other material may be considered. Reference should be made the standard details in Appendix 5. For clarity, Unbound Roads (Type 1) shall not be accepted as an appropriate adoptable standard road. This remains the case even in circumstances where the road will not be adopted. 4.26 Standard detail SD 08/002 Rev. B (see Appendix 5) will normally be used where there are more than two new properties serviced from a single access off a double track road. 4.27 Standard detail SD 08/004 Rev. B (see Appendix 5) will normally be used where the access joins a single track road.
Page 44
44 4.28 Standard detail SD 08/005 Rev. B (see Appendix 5) shows an access across a footway. 4.29 Standard detail SD 08/006 Rev. B (see Appendix 5) shows a service bay and may be required by the Roads Authority on faster double track roads. 4.30 Road Opening Permits must be obtained before any work is carried out in forming accesses. 4.31 Accesses must be constructed in accordance with the Roads Authority specification; on satisfactory completion the area within the road corridor will become part of the public road. Parking Provision 4.32 Argyll and Bute Councils parking standards are detailed Table A8 of this document Any variations to the parking standards must be evidence based and subject to approval. 4.33 Each car parking space should normally measure no less than 2.5 metres by 5 metres. 4.34 Integral garages will not be counted towards parking provision. Free standing garages of at least 6m x 3m within 30m of the dwelling can be counted unless there is a site specific reason not to. Car ports will generally be counted as spaces. Private Accesses – Commensurate Improvements 4.35 Where there is an existing access serving a small number of properties it may be acceptable to allow additional properties to be constructed without the requirement for major upgrade works. The main principle behind any agreement by the Roads Authority will always be road safety. Example: An existing private access serving two dwellings, the Roads Authority may allow up to a further three dwellings; the maximum permitted dwellings serviced by this type of access will be five. Dependent on the local environment commensurate improvements may include: improvements to the junction layout; visibility splays; surfacing of junction; passing places; turning head at the end of the private access drainage; surface condition of the private access. 4.36 Where an existing private access served six dwellings and an application was submitted for another dwelling, the Roads Authority may consider permitting this on the condition that no further development is allowed. In the case where further development was confirmed to be prohibited or the land remaining was undevelopable, it may be considered unreasonable for the Roads Authority to
Page 45
45 ask for a road to adoptable standard. Notwithstanding this, improvements may still be requested on the grounds of road safety improvements. Any further application would be subject to a road to adoptable standard. 4.37 A “road to adoptable standard” is for the Roads Authority to define. The variation may include road widths or construction depth, for example, commensurate to the scale of the development, however; Unbound roads (Type 1) shall not be accepted as an appropriate adoptable standard road.
Page 46
46 5.0 Small Housing Developments (for use for 6 to 10 dwellings) The following clauses must be referred to by developers proposing to reduce standards for proposed developments between 6 to 10 dwellings. A. In normal circumstance the road must be constructed as per the normal processes outlined in Section 2 of this document or otherwise as per the National Roads Development Guide. An RCC will be required, and a Road Bond will be required as appropriate. B. Where there is a desire or requirement for the proposed road to be adopted but there are justifiable technical or planning reasons that wouldn’t allow fully compliant road infrastructure to be developed: i. A reduced road standard may be acceptable. ii. Any deviations from standard road construction must not compromise road safety. In this regard reduced visibility splays will not be acceptable. iii. Any other proposed departure from standards must be submitted to the Roads Authority for consideration. Early engagement is encouraged. iv. Any agreement to a departure from standard must take into consideration the local roads environment. v. Financial considerations will not be considered as a justifiable technical reason to vary standards. Note: an RCC will be required and a Road Bond will be required as appropriate. C. Where the developer does not wish the road to be adopted as the proposal is unable to meet the principles set out above, then the following may be acceptable, subject to agreement with the Planning Authority: i. As noted above, road safety must not be compromised, even where the proposed road is not to be adopted. ii. The access shall be surfaced with a bituminous material for the first 5 metres from the edge of the adopted carriageway or back of any local road widening. The construction depth shall be as per the detail below (construction may be revised subject to appropriate CBR values being met): iii. The first 10m shall be 5.5m wide at the junction, thereafter the width may be 3.7m with intervisible passing places. A turning area at or near the end of
Page 47
47 the road as per the details below must be provided. The maximum length of road shall not exceed 150 linear metres. iv. The remainder of the road can be a bound surface or other material as approved, however; Unbound Roads (Type 1) will not be accepted as an appropriate standard road. The depth of construction may vary dependent on local ground conditions. As a minimum, a typical construction detail should include 200mm Type 1 sub-base and 100mm of bituminous material. Planings may be used outwith the adopted road section. v. A service bay and communal bin storage area shall be provided at or near the access. Note, refuse collection vehicles shall not drive onto private roads and, therefore, not collect bins from individual properties on private roads. vi. In rural or semi-rural locations there may not be a requirement for a system of street lighting to be installed; however, note the following: a. If a lighting system is installed on a private road, the lighting shall also remain private and will not be maintained by the Roads Authority. b. A requirement to install suitable ducting at construction phase may be required even where no proposed system of street lighting is included in the design. This is allow future upgrades while minimising costs. vii. Parking provision shall be as per the detail set out in Section 2 of this document. viii. An RCC or similarly controlled document and associated Road Bond may be required. ix. Road Opening Permits must be obtained before any work is carried out in forming accesses at the public road interface. x. Arrangements must be made providing assurance that a maintenance agreement for the road will be included as a burden on the Title Deeds for each property in perpetuity.
Page 48
48 Note: Financial considerations will not be considered as a justifiable technical reason to vary standards. 6.0 Variation on Road Standards for Specific Islands 6.1 This section is only applicable to applications sited on the Islands of Colonsay, Coll, Tiree and Jura. The exceptions provided for within this section are made primarily due to the extreme difficulties in accessing hot material from mainland quarries. 6.2 The construction standard may be varied to allow concrete or unbound (Type 1) roads to be constructed. Other material types may be considered. 6.3 The provision of footways & verges may still apply. 6.4 Where the proposed road has a carriageway of less than 5.5m width, there may be a requirement for intervisible passing places. 6.5 This variation only applies up to a maximum of five dwellings served by a single access. Subject to approval by the Roads Authority, this may be extended to developments of up to 10 dwellings for new developments. 6.6 The road will remain private and will not be adopted onto the Public List of Roads. 6.7 The access shall be surfaced with a bound material for the first 5 metres from the edge of the carriageway or back of any local road widening. The access shall be formed as per the appropriate standard detail drawing (SD/08/004/Rev.B, refer to Appendix 5). 6.8 Road Opening Consent will be required. 6.9 Notwithstanding the above, it remains the preference of the Roads Authority that new roads are constructed in-line with normal adoptable standards and subsequently adopted onto the Public List of Roads.
Page 49
49 7.0 Guidance on the Adoption of Private Roads other than via the RCC Process 7.1 The adoption of a new road is covered elsewhere within this document and the decision to adopt or not is generally made at time of application through the Roads Construction Consent process. There are, however, a number of private roads - roads which have not been added to the Public List of Roads - within Argyll and Bute. The adoption policy for the latter is covered within the Policy set out in 2012 which can be found at https://www.argyll- bute.gov.uk/moderngov/ieListDocuments.aspx?CId=257&MId=5320&Ver=4 under Item 19. 7.2 There are specific legal requirements regarding the adoption of a private road onto the Council's List of public roads. These are: i. The Road must be a road as defined by the Roads (Scotland) Act 1984 Section 151. ii. In order for an application to be considered by the roads authority it must be supported by a majority of the frontagers (based on actual % of frontage not the number of frontagers) of the land along both sides of the road being offered for adoption. iii. The proposed road must meet Argyll and Bute Councils road adoption standards. 7.3 In general, the road adoption standard will be those set out in the National Roads Development Guide or their variations set out in this Technical Guidance, however, exemptions may be considered, for example street lighting may not be required depending on local environment, particularly in rural settings. 7.4 An application for road adoption must provide detail including: i. Existing road layout. ii. Proposed improvements to meet roads adoption standards including as a minimum (list not exhaustive): a. Drainage; b. Lighting; c. Roads width; d. Gradients e. Services; f.

50 8.0 Developments on existing Private Roads 8.1 While in most circumstances a new development of more than 5 dwellings will require to be served by a public road (i.e. an adopted road), there are occasions where a planning application will require the roads authority to consider further development from an existing private track or access road. 8.2 The Councils Local Development Guide, Supplementary Guidance TRAN4 provides guidance where this kind of development may be acceptable subject to the following clauses: i. the access is capable of commensurate improvements considered by the Roads Authority to be appropriate to the scale and nature of the proposed new development and that takes into account the current access issues (informed by an assessment of usage); AND the applicant can; ii. Secure ownership of the private road or access to allow for commensurate improvements to be made to the satisfaction of the Planning Authority; OR, iii. Demonstrate that an appropriate agreement has been concluded with the existing owner to allow for commensurate improvements to be made to the satisfaction of the Planning Authority. 8.3 Points (ii) and (iii) are for the Planning Authority to determine, this section deals with point (i) and the general minimum requirements which will be sought by the Roads Authority. These will normally be made in reference to road safety, sustainability, emergency and service access, economic feasibility (commensurate to the scale of the proposed development). 8.4 Unlike new developments there is no defined upper limit on the number of dwellings that may be served by an existing private access; each application will be considered on its own merits and principally based on environment, local context and predicted access requirements (for example, deliveries, and refuse collection). Where feasible, commensurate improvements may be required to allow further development. Where the required commensurate improvements are beyond what could be reasonably considered as appropriate to the scale of the development, the Roads consultee response must be a refusal. Road safety must not be compromised. 8.5 The following will be considered for any application to develop existing private access roads; note this is not an exhaustive list: i. Junction interface with the public road a. Access must be safe; b. Sightlines will be assessed on the posted speed limit, however; this may be reduced pending a traffic/speed survey and subject to suitably robust data on mean speeds; c. Formed bellmouth with radii appropriate to access requirements (e.g. deliveries); d. A service bay will, in most cases, be required.
Page 51
51 e. Where possible, the private access should be widened out to 5.5m for the first 10m. f. The access shall be surfaced with a bituminous material for the first 10 metres. g. In some cases, it may be necessary for the developer to carry out works on the public road along the frontage of the development, including carriageway widening works, footways etc. h. Junctions must be improved to ensure that no water, debris (mud, stone, gravel etc.), filth or any other offensive matter spills onto the public road. ii. Refuse collection / bin stores a. Where the private road has poor geometry or carriageway width it may not be appropriate or safe for refuse collection vehicles; b. It remains the Councils general position that RCVs will not use private access roads. c. The developer may be required to construct a bin store / collection point contiguous with the public road (via a service bay) for all properties served by the road. This may include existing dwellings. iii. Carriageway widths a. To accommodate access for service and delivery vehicles, carriageway widths should be no less than 3.5m b. In line with Fire Scotland and nation building standards guidelines, this carriageway width shall be widened out to 3.7m adjacent to low rise buildings, increasing to 4.5m where buildings are in excess of 9m high. This is to facilitate the deployment of firefighting equipment. iv. Gradients a. Must be no more than 5% over the first 10 metres from the edge of the public road; b. Away from the public road interface, maximum gradients must not exceed 8%. The gradient on the approach to the public road must also take cognisance of the horizontal alignment; further measures may be required to prevent runaway vehicles crossing onto the public road at speed, for example, introduce a series of measures to slow vehicles down on the approach to the public road. v. Drainage a. Positive surface water drainage and/or SUDS may be required; vi. General Road layout a. Where the private access interfaces with a single track adopted road network, it may be acceptable for the private road to also be single track. b. Where a. applies, there may be a requirement for localised widening, including corner widening, to ensure safe access for larger vehicles.
Page 52
52 c. Where this is the case, intervisible passing places will be required. Inclusive of the carriageway width, passing places at their widest point shall be no less than 5.5m wide. d. On single track private roads, intervisible passing places to be provided at 100 metre centres (maximum distance). vii. Turning head / areas; a. Turning arrangements appropriate to predicted use will be required to minimise or remove entirely reversing manoeuvres in the interest of road safety. viii. Dwelling accesses a. For new developments, no access shall be constructed within 25m of the junction with the public road network. b. Within the private road network, accesses should be located a minimum of 25 metres away from the nearest adjacent junction. ix. Other Road Safety: a. Where there are no footways then verges must be of sufficient quality to provide good, safe step-offs. b. The development may require to provide a walked route assessment or similar for the section of private road from the development to its interface with the public road. c. At the junction with the public road a safe pick up point / drop off point must be provided. 8.6 Arrangements must be made providing assurance that a maintenance agreement for the road will be included as a burden on the Title Deeds for each property in perpetuity. It may not be possible to apply this retrospectively to existing properties, where this is the case, the burden of the maintenance of the whole private road length must be placed on the new development. If this cannot be done, the Roads Consultee response must be a refusal. 8.7 Further to the above requirements, it may also be a requirement that servitude or wayleave arrangements are in place to allow access for public utilities. 8.8 The above requirements may be extrapolated to cover commercial and industrial developments. This may lead to increases in minimum standards; for example, an increased radii at the public road to incorporate swept paths for HGVs. 8.9 The Applicant will submit a plan providing detail of the proposed commensurate improvements for written approval by Roads, prior to the Planning Decision Notice being issued. The Roads consultee response will normally be deferred until agreement has been reached. 8.10 Drawings showing the junction (at the interface with the public road) sightlines within the site edged red. If the land is not under the Applicant’s control then a Section 75 Legal Agreement shall be required. 8.11 No work shall commence on site until all of the commensurate improvements have been carried out to the satisfaction of the Roads Authority.

These figures already include an allowance for inflation over a three year period (the minimum duration of a construction consent). 2. The costs are based on the Council doing all the work. Obviously it is more costly to take over someone else’s job and complete it; to compensate for this the following procedure should be adopted: a. Add 25% where the estimated cost is less than £10,000; b. Add 15% where the estimated cost is between £10,000 and £25,000; c. Add 10% where the estimated cost is between £25,000 and £50,000. 3. Where the bond has to cover such items as major structures, or substantial amounts of excavation or fill, full details should be sent to Roads HQ who will carry out the estimate. Elaborate SUDS schemes will need to be considered in their own merit and should be priced individually.

65 Roads (Scotland) Act 1984 Security for Private Works (Scotland) Regulations 1985 Guidance notes for developers In terms of Section 17 of the Roads (Scotland) Act, 1984 and the Security for Private Roadworks (Scotland) Regulations 1985 (S.I. 2080) you, as a developer, are required to make financial provision with the Council, as Local Roads Authority in order to safeguard the completion of housing development roads which are the subject of a Construction Consent. Such Provision, as required by the Regulations, may be the form of a Road Bond or deposit and this will serve to protect prospective house purchasers from having to bring incomplete roads up to adoptable standards. You are unable to commence building works adjacent to any road permitted by a Construction Consent until you have met the requirements to the above regulations which came into effect on 1 April 1986. In terms of Regulation 6, the security shall be an amount to meet the cost of constructing or completing the construction of the said roads. Also to calculate the amount of that security by objecting estimating and negotiation. In terms of Regulation 5, that security shall be either a bond in favour of the Council or a cash deposit of a sum equating to that security. Such bond or deposit shall be lodged with the Council at the office where your construction consent was issued. In terms of Regulation 16, any person who carried out building works in contraction of these regulations, shall be guilty of an offence. It would, therefore, be in your interests to make early contact with the Roads Authority, who will be able to advise you fully on these procedures. Copies for form CC7 should be completed and returned with the security. Copies of the regulations are also available for inspection at the appropriate office. Road Bond CC7
