The plans cannot be approved as submitted and will require the following changes /corrections prior to final approval. Engineering is available from 2 -4 PM on Thursdays to discuss these review comments. Please contact Mr. Allan Schuck at 296.5832, ext. 3069, to schedule an appointment. A. Final Site Plan (SDP- 2007 - 00053) 1. Please provide copies of easements for off -site work. Any proposed improvements or disturbance within 5 feet of property lines, or any wall within one -half its height of a property line, requires a construction easement. [Policy. Temporary easements may be plats, deeds, recorded documents, or letter of permission signed by the owner.] 2. Plans need to have a professional seal, signed and dated. [18-32.6.1] 3. Please shade any existing critical (25 %) slopes. [18- 32.6.6, 14 -302] 4. Show the existing vegetation on all sheets. Describe how the trees will be relocated and protected. 5. All slopes greater than 3:1 need to have a low- maintenance (not grass) ground cover specified on the plan. [Policy] 6. Show a permanent drainage easement with appropriate dimensions and labels for drainage through adjacent property to the water quality BMP. [18- 32.7.4] 7. The entrance landing appears to exceed 4% for the first 40' from the intersected street (Five Springs Road). [18- 4.12.17] 8. Show and label the available sight distance at the entrance to Five Springs Road on the plan. Checklist] 9. The C -1 structure shows as a MH -1 on sheet 9 profile view but shows as a DI -2A in the schedule table. Please revise accordingly. 10. We recommend the dumpster pad detail or specification to be a minimum 4000psi at 28 days, or stronger. [Checklist] 11. Provide typical retaining wall details. [Design Manual] 12. The following comments are in reference to Sheet 7, stormwater management plan: [Checklist] a. DA -1 is labeled as 0.7 acres but appears to be much smaller in area. Please revise accordingly. b. Show hydrologic coefficients used for each drainage area. 13. The following items are in reference to the storm drain table provided: [Checklist] a. It is acceptable to use the table provided, VDOT table, or Albemarle County table as long as all information is provided and consistent. Engineering Review Comments Page 2 of 2 b. Label the structure ID's using the same format as on the plan (B -8, C -1, etc...). c. List the drainage area to each structure. d. Provide the hydrologic coefficients for each area. B. Erosion Control Plan (WPO- 2007 - 00035) Narrative 14. The narrative appears to be adequate with this submittal. Plan 15. Show the existing vegetation and the required tree protection measures 5' outside of the actual drip line for trees to be saved and /or relocated. [VESCH 3.38] 16. It appears that the limits of clearing and grading may need to be adjusted to allow adequate space for grading the sediment traps and diversion dikes, retaining walls, installation of the water line to the street, and the sewer hook -up. 17. Show temporary seeding symbol on the plan sheet. [VESCH 3.31] 18. Show stockpile location within the limits of clearing and grading. [Checklist] 19. Show a location for staging, parking and other related activities. [Checklist] 20. Show and label the proposed contours for the sediment traps with the necessary grading. [VESCH 3.13] 21. Show the construction entrance on the plan sheet as 70' in length per detail. [VESCH 3.02] 22. Please show ESC and stabilization measures for the installation of the new water line to the street. Checklist] 23. Final stabilization for slopes greater than 3:1 needs to be a low- maintenance ground cover not general permanent seeding from ESC specs. Show permanent seeding on all other areas. [Policy] C. Stormwater Management and Mitigation Plan (WPO- 2007 - 00035) 24. The water quality swale constructed with Phase I is not sized to treat the additional impervious related to Phase 11, therefore water quality requirements need to be addressed with this plan. [17- 303, VSWMH] a. The proposed stormwater management plan (sheet 7) shows a project drainage area of 1.75 acres to the existing water quality swale. Using 1.75 acres as the project drainage area in the BMP computation worksheet we have calculated the impervious area to be 60% and the required removal rate to be 61 % at the location of the existing BMP. Water quality swales have a target removal efficiency of 35% and is not adequate to treat for the additional impervious associated with phase Il. [VSWMH 3.13, table 3.13 -1] b. One option is to treat for water quality onsite and tie into the storm drain that runs along the NE property line and bypass the existing water quality swale. c. The second option is to upgrade the existing water quality swale to address the entire build -out at 61 % RR. d. A permanent drainage easement will need to be submitted for use of the storm drains and the water quality BMP on the adjacent property if the second option is chosen.
