Attach written justification SURETYBONDING If required to construct a street, the subdivider shall pay to the county a fee equal to the cost of the inspection of the con- struction of any such street. These fees shall be paid prior to completion of all necessary inspections and shall be deemed a part of the cost of construction of the street for purposes of section 14-435(B). The bond process and forms can be found at the document center under bonds. After a plan is approved, a bond estimate request for must be submitted to the Community Development office with the required fee. The owner signatures will be verified for each parcel affected, and estimates will be prepared by the engineering reviewer. A bond amount will be pro- vided to the owner. Bond agreements will be prepared by the county, and when properly completed by the owner, will be reviewed and signed by the County Attorney and County Engineer. Please allow a few weeks for this process. •11l: ■■t• ROAD PLAN CHECKLIST A road or street plan is an engineered construction plan for a public or private road or alley. It also contains necessary infrastructure for the road, like drainage inlets, pipes, ditches, culverts, residential and commercial entrances, slopes, retaining walls, signs, pavement markings and any other items necessary for the road. A road plan must be a stand-alone document, and titled as a road plan. A road plan is not a site plan, or a stormwater plan, or an erosion control plan. Please do not attach any other plans to the road plan. The exception is when the Albemarle County Service Authority has insisted in some cases that utility plans (water and sewer) be part of the road plans, and this has been permitted. A road plan must contain a title sheet specifically for the road plan, a plan view of the road, a profile of the road, and specific and typical details for the road sections. Please also reference the Design Manual in addition to this checklist. Application information: Z Completed application and fees. No review is provided without applications and fees. Plans containing both public and private roads should pay the higher fee for private roads. ❑ Copies of federal and state permits for any wetland or stream disturbance. (Army Corps, VDEQ, etc) [18-32.1.2, 14-311] Title information: 9 Project title. Titles should be appropriate. It should be a road or street plan, not a site plan, subdivision plan, or erosion control plan, etc. i7 Professional seal, with original signature and date. [18-32.6.1] ✓ Content: The road plan must contain, for each road/streetlalley, at a minimum 1. a plan view, customarily at F=50' or better. 2. a profile view 3. a typical cross-section Plan View: [18-32.6.2, 14-304, Subdivision Ordinance Article IV Division 2, VDOT SSAR] 0 Accurate current existing topography at the time of submittal, including all existing site features, and any recent disturbances, all at a legible scale. W Date and source of the topographic information: All topography should be at least visually field verified by the designer within the last year {Aerial topography is often noticeably inaccurate. problem where early or mass grading plans have occurred previously. In these cases, the topog_raphv needs to be updated. } Z WPO buffer limits; 100' from stream or wetland bank, 200' from reservoirs, or floodplain limit if greater [17-600] W Floodplain limits, including 100yr flood limits for any channel with a drainage area of 50+ acres [ 18 -32.6.2d, 18-30.3] Z All existing easements (access, drainage, sight, sanitary easements, etc.) with deed book references, locations and dimensions. •11l: ■■t• ROAD PLAN CHECKLIST V All proposed streets included, with right-of-way and street names 7 Stationing at 50' minimum on all proposed streets, on plan and profile 1 Street horizontal curve start point, end points and radii labeled, meeting standards Z Cul-de-sacs provided on all dead-end streets or alleys (see the Design Manual reference details) 9 Street edge of pavement or curb radii labeled at all intersections and turnarounds (see the Design Manual reference details) ❑ Roundabouts designed per VDOT and ASHTO guidelines ❑ Guardrail over any slope steeper than 3:1, wall, or drop-off greater than 4', with start and end sections labeled, and VDOT designations (GR-2, GR-2a, etc.) (see the VDOT Road Design Manual. Guardrail placement is complicated and subject to a lot of judgement and variation. This is a quick rule -of-thumb summary.) V Pavement markings dimensioned and labeled 9 Signs for traffic control shown and labeled: speed limit on all streets, stop signs at all intersections 9 Street name signs at every intersection, typically placed opposite stop signs [should reference County Road Naming and Property Numbering Ordinance and Manual] W Street tree locations, species and height or caliper (typically to be reviewed by Planning) Grading: V Proposed topography at minimum 2' contour intervals — tied into existing contours, as well as all proposed site features. (Sites with less than 6' of grade change should consider using smaller contour intervals.) V Proposed slopes are all 2:1 (horizontal:vertical) or flatter {Design Manual, section 81 9 Proposed slopes steeper than 3:1 have low maintenance (not grass) ground cover specified on the plan {Design Manual, Section 81 W Show existing critical (steep) slopes on plans (See County GIS, Steep Slope Overlay). Existing critical slopes are not disturbed, unless a waiver or exemption has been granted for the disturbance. 9 Retaining walls should be accurately shown on plans, reflecting material thickness and batter where such measurements may affect layout. Retaining Wall Plans checklist. ❑ Any walls supporting roads or necessary infrastructure require engineered plans (not generic manufacturer's details) and computations. {Design Manual, section 81 This will also be required where walls are close to property lines and there is the danger of affecting neighboring property, either during construction, with later failures, or with pedestrian or vehicle safety. These concerns can be alleviate with layout spacing also. In any case, retaining walls will require building permits at construction. Required Easements: [Zoning Ordinance 18-32.7.4, Subdivision Ordinance, Article IV, Div. 4] Z All proposed permanent easements, dimensioned and labeled Examples of easements are: • sidewalk easements for sidewalks to be maintained with streets outside right-of-way. It is preferable that sidewalk be inside street right-of-way. • drainage easements for any drainage passing through the site from off -site, or for drainage crossing proposed property lines. • stormwater management easements over all facilities and associated structures and access • interparcel access easements • intersection or entrance sight easements •11l: ■■t• ROAD PLAN CHECKLIST ✓ All drainage easements are a minimum 20' wide. Required width: 10'+(pipe dia. or channel width) + 2'+ 2(depth-5'). The pipe, channel or structure must be within the center third of the easement. {Design Manual, section 61 7 No structures or trees within drainage easements {Design Manual, section 61 Z Label drainage easements beyond public rights -of -way as `Private'. A deed of easement for the maintenance of these will be required for approval. Entrances and right-of-way improvements: [per VDOT Secondary Street Acceptance Requirements (SSAR), and VDOT Road and Bridge Standards] 7 Only approved entrances are shown. Placing entrances on road plans should not be a way of circumventing site plan review of entrance placement or number, or adequate review of traffic, spacing, turn lanes, etc. 7 All entrances have a VDOT designation [PE-1, CG-9a, etc). In the case of dense residential development, concrete entrance aprons are important to continue drainage on the street side, and to control fine grading of asphalt and sidewalks. Z Commercial entrances do not exceed 4% grade for a distance of 40' from the intersected street, measured anywhere in the entrance [ 18-4.12.17] Z Unobstructed sight distance lines at entrances, more than 10' x speed limit, plus next 5mph increment. For example: sight distance for 25mph design speed limit = 10' x 25 + 30 = 280'.

See Section B(1)-4.G Curb and Gutter Designs, Figure 6- Detail Back of Curbs in VDOT Road Design Manual W Planting strip if applicable, 6' minimum width [ 14-422] 9 Ditches dimensioned at 3:1 slope from shoulder, 1' depth min., and 4' min. width from shoulder to ditch centerline, for rural sections V Alleys have 12' pavement width, with 14' wide stone base [ 14-410] 9 Transitioning detail (20' minimum) for roll-top curbing in front of any inlets 9 Typical sections for proposed channels with locations referenced from the plan view sheets V Sidewalk detail or specification to be a minimum 4" stone base and 4" concrete of 3000psi at 28 days, or stronger. [VDOT App. B, Subdivision Street Design Guide, and 14-422] ❑ Retaining wall details referenced from plan, if detailed plans and comps were not required. This is only really applicable to standard VDOT gravity walls. Walls not affecting the road should not appear on road plans. ❑ Rural section ditches may not be deep enough for 15" diameter culverts within the ditchline if the ditches are only 1' deep. This usually involves moving the ditchline away from the road at driveway locations, which may not be possible in denser development. Ditch and driveway culvert plans will need to accommodate these situations.
