HomeMy WebLinkAboutSDP200600128 Approval - Agencies 2008-03-246 I : ; Auth4rity Mr. Charles Armstrong Southern Development 170 South Pantops Drive Charlottesville, Virginia 22911 EMMMEM= Enclosed is a copy of the construction plan approval letter dated March 24, 2008 . A copy of the approved plan shall be on the job site throughout construction and shall be modified by the contractor to show as-built conditions. It is the contractor's responsibility to provide this information to you and your consultant for use in developing the final as-built plan, which shall be submitted in the format of one paper copy and one mylar copy. A local facility fee will be charged for the proposed connection(s) to the existing sewer main at the prevailing rate at the time of the preconstruction meeting. This fee is to defray, in part, the cost of installing the existing sewer main and is due prior to connecting to this main. You will be advised of the amount of applicable connection fees for the meter installation at a later date. A preconstruction conference is required prior to the start of construction. I can be reached at 977-4511 to schedule the meeting. The preconstruction conference will help to ensure project coordination, clarify ACSA requirements pertaining to construction, and answer any questions you may have. We have also enclosed copies of our "Utility Inspection Policy," "Letter of Dedication," and "As-Built Guide" for your information. These documents should be reviewed before the preconstruction conference. A water and sewer construction inspection fee will be invoiced to you at the time of the preconstruction conference. The inspection fee for this project is $773.52 for the water system and $847.17 for the sewer system, for a total of $1,620.69. A plan review fee will be invoiced to you within the next few days. It will be based upon the actual time of plan review billed at the current hourly rate established by the Board of Directors of the ACSA. At the end of the project, you will also be invoiced for an as-built plan review fee. It will be billed in the same manner as the plan review fee. 16` i Road 0 Charldfesv i Ile, \iA '22`911 o Tel (434) 977 45 - 1 1 * Fax (434) 979-069o' wwwserviceouthority.orq I - The ACSA cannot set permanent water meters until construction has been completed and approved for operation. The utility easements shall be reviewed and approved prior to recordation. Copies of the deed of easement, plat, as-built plan and Letter of Dedication shall be submitted as soon as possible following installation of the utility systems. Timely submission of these documents will help you avoid delays in receiving utility service. Please be advised the Albemarle County Department of Community Development is instructed to hold the sewer bond amount at a minimum value of 20% of the original amount until the dedication of the utility systems is completed. The plan approval is valid for a period of 18 months. If construction is not in progress at the end of the approval period, the approval shall be void. If you have any questions or if we may be of assistance, please give us a call at 977-4511. Sincerely, Jeremy M. Lynn, P.E.

Davis, A.I.C.P. 250 Pantops Mountain Road Charlottesville, VA 22911 Keith Lancaster, Planner Southern Development Homes 170 South Pantops Drive Charlottesville, VA 22911 Dear Keith: 5 March 2008 Soon, I hope, Pavilions II will go to the Planning Commission. I wanted you, and the Planning Commissioners, to know how impressed I am with the excellent work you and Charlie Armstrong have done with the North and West areas. Current plans for these about- to -be- developed areas are vastly improved over the initial and early plans. As you are aware, I've been over every inch of every plan with a magnifying glass! No complaints now, and only two suggestions. Given the zoning, the terrain, the plans you started with, and other constraints, North and West are as good as they can get. Both areas are much better for the people who will be living there. At the February meeting of the Building and Grounds Committee meeting of Westminster Canterbury of the Blue Ridge I brought members up to date about Pavilions II and other work going on, or about to occur, on Pantops. Residents here are, of course, quite interested. The following is from my report: Southern Development has, in my opinion, done an excellent job in changing the original plans to something much more workable and vastly better for the people who will be living there. The final plans also are better for present and future residents of WCBR. Charlie Armstrong, an environmental scientist, and Keith Lancaster, a planner, are to be commended. I am sending Southern Development a letter that can be forwarded to the appropriate County employees and to the Planning Commissioners. My only concerns remaining relate to West. One — extending the street/dumpster access /fire engine turnaround two feet. Two — encouraging the Home Owners Association to plant appropriate trees on the slope behind the townhouses where trees are being removed; this will lessen erosion caused by runoff and the probability of additional erosion caused by children racing around on foot, bicycle, etc. One question, following discussion with our tree and nursery experts: Is the Sweet Gum proposed for planting throughout the development a variety that won't create a nuisance for the future residents? The East area is still of great interest to us. Some of East, shown "grayed out" on the latest plans, still needs tweaking. Again, the changes Southern Development has made on the North and West areas of Pavilions II result in a much better place for people who will buy and live there.

The sight distance has been adjusted to meet the 280' that we requested. However, we would like to point out that the SD eye should be located 20' from the middle of the nearest travel lane because sheet 5 of the plans shows that it is about 30' from the middle of the nearest travel lane. Therefore, more sight distance is being provided than is required. The sight distance easements can be readjusted in light of this. If they are not, the current plans are acceptable.

Albemarle C6Thty Community Development Engineering Review Comments Page 2 of 2 C. Stormwater Management Plan (WP0200700001) With the increase in drainage area from Westminster Canterbury, the SWM plan serving this project (WP0200400011) needs to be revised to show that the pond can handle the additional drainage. This drainage was not accounted for with the Luxor plan. Rev3: Plan approval pending SWM amendment submitted for Luxor. D. Erosion Control Plan (WPO200700001) The following comments pertain to the West part of the project: 4. Please provide adequate E &S measures for the site. The site below the stormwater conveyance channel remains unprotected during portions of construction. Rev3: E &S measures are not adequate. Inlet protection is only adequate for I acre of drainage area. Several parts of the construction sequence are confusing: sequence 4, sequence 9. Both appear to refer to a 36 "pipe and structure 26 which do not appear on the plans. Do you intend to direct the runofffrom Westminster Canterbury through the engineering channel until the pipe system is in place? The plans show the runoff draining through the existing 30 "pipes (not shown) until the new pipe system is put in place. It also seems like it will be much more costly to fill existing pipes with sediment which have to be cleaned out later than simply diverting most of the runoff to the existing basin. The E&S plans may need to be phased. It appears the plans were designed around the final build out of the plans rather than existing conditions. 6. An E &S bond amount will be computed by the County once the plans are approved. d 0 1 Rcal COUNTY OF ALBEMARLE Department of Community Development 401 McIntire Road, Room 227 Charlottesville, Virginia 22902 -4596 Phone(434)296 -5832 Project: Pavillions at Pantops Phase iI [SDP200600128] Plan preparer: David Jensen, W &W Associates [fax 978 -1444] Owner or rep.: North Pantops Townhouses, LLC [fax 296 -3510] Contact: Keith Lancaster, Southern Development [fax 295 -0895] Plan received date: 08 June 2007 (Rev2) Date of comments: 22 June 2007 (Rev2) Reviewer: Jonathan Sharp Fax(434)972 -4126 It appears road plans have yet to be submitted for this project.

Also, please show the 30" pipes on all applicable plan sheets (not only the landscaping plan). Please address how the ditch will make sharp turns. The ditches may need to be revised to turn more naturally and /or be deepened. 3. For the North phase, EC -1 going from Structure 10 to a ditch makes a sharp turn. Please revise this. 4. There are 1:1 slopes shown for the West Phase. The maximum allowable steepness is 2:1. 5. There is a concern with runoff drainage through more than 3 lots at a time. This could cause drainage problems if an owner decides to regrade his yard or put in a fence /deck/patio, etc. 6. Please provide any necessary easements. B. Stormwater Management Plan (WP0200700001) With the increase in drainage area from Westminster Canterbury, the SWM plan serving this project (WP0200400011) needs to be revised to show that the pond can handle the additional drainage. This drainage was not accounted for with the Luxor plan. C. Erosion Control Plan (WP0200700001) The following comments pertain to the North part of the project: 1. There is silt fence located outside the limits of disturbance. There is tree protection that appears to be placed in an erroneous location (possibly where previously proposed sewer pipes ran). 2. The outlet protection for the outfall of structure 10 is not straight. 3. There is grading still shown in a tree protection area. The following comments pertain to the West part of the project: 4. Please provide adequate E &S measures for the site. The site below the stormwater conveyance channel remains unprotected during portions of construction. 5. Please design the stormwater conveyance channel to bend more naturally, or provide a necessary design so that ensures that all of the drainage will be contained within the channel /pipe system. 6. An E &S bond amount will be computed by the County once the plans are approved. ko)v f may• M COUNTY OF ALBEMARLE Department of Community Development 401 McIntire Road, Room 227 Charlottesville, Virginia 22902 -4596 Phone(434)296 -5832 Project: Pavillions at Pantops Phase II [SDP200600128] Plan preparer: David Jensen, W &W Associates [fax 978 -1444] Owner or rep.: North Pantops Townhouses, LLC [fax 296 -3510] Plan received date: Date of comments: 28 Mar 2007 (Revl) 02 Apr 2007 (Revl) Reviewer: Jonathan Sharp A.

[18 4.12.15c] Rev]: comments not addressed. For Pavillions II West, the parking area with S spaces appears to have mislabeled spot elevations. The parking area with 7 spaces appears to e -viceed 5% slope. For Pavillions II North, lam unsure as to how the parking will maintain a maximum S% slope, as the adjacent travelways exceed S%. 4. Parking with 16' stall depths cannot overhang sidewalk. [18- 4.12.16c6] Rev]: comments not addressed. Parking adjacent to sidewalk must maintain 18' length. 11. It appears that the existing 30 inch pipe running to the fore bay for Phase II — West appears to be undersized resulting in pressure flow. Perhaps once the drainage area values are corrected, this will not be the case. If it is still undersized, the pipe size will need to be increased or changes made so Albemarle County Community Development Engineering Review Comments Page 2 of 3 that pipe flows do not exceed their capacity for the 10 year storm. Revl: Please provide profiles and calculations to show that the existing pipe system running to the forebay (fpond 3 for Pavillions H West is adequate. 12. (Revl) The proposed retaining wall shown on Pavillions II North is a concern as it is very close to proposed lots and buildings and can potentially be a hazard. Engineering recommends stepping the wall, thus decreasing the drop. Please provide detailed drawings and provide railing on the walls. B. Stormwater Management Plan (WPO200700001) No stormwater management plans are necessary; stormwater management for Pavilions II was addressed with WP0200400011. Revl) A stormwater management amendment has been submitted for WP0200400011. The amendment proposes that pond 3 be removed or decreased in size. As this has an affect on Pavillions 2, the amendment will need to be approved before Pavillions 2 can be approved. C. Erosion Control Plan (WPO200700001) The following comments pertain to the North part of the project: The site is not protected below structure 8 (pipe outlet). Silt Fence does cannot be used for diverting or trapping runoff. Rev]: Please label the section of the diversion dike running through the fill area as a Temporary Fill Diversion (FD), Minimum Standard 3.10 in the VESCH. Along with the temporary fill diversion, include a note stating: "Fill diversion to be installed at the end of'each work day or before a rainfall event. Exact location offill diversion to be located in the field. " 5. There is work shown in tree protection areas. Revl: There is still grading going through a tree protection area. Please revise the grading so that grading does not occur in the tree protection areas. The following comments pertain to the West part of the project: 6. Please show the drainage areas draining to the sediment traps. Revl: Please show contours for all areas which drain through the site. The diversion dike channeling the runoff from Westmimster Cantebury to the existing forebay is inadequate. Diversion dikes are limited to 5 acres of runoff. Also, there is grading shown on both sides of the diversion. E &S measures should not be in the way of construction activities. Revl: see comment 10. 9. Engineering recommends not using a drop inlet sediment trap, as they do not work well in this area. If a drop inlet sediment trap will be used, it must be designed in complete accordance with the VESCH. The drainage area draining to the drop inlet trap cannot exceed 1 acre. Also, the max depth of the trap cannot exceed 2 feet below the top of the inlet structure. Rev]: see comment 10. 10. The culvert inlet protection trap must be drawn more accurately on the plans. The plans should include the location of the rip -rap, and storage should only include the horseshoe shaped volume Albemarle aunty Community Development Engineering Review Comments Page 3 of 3 around the outside of the rip -rap. Revl: The proposed use of diversion dikes and sediment trapping measures in not in accordance with State code. It is not realistic to split the flow through the drainage easement using diversion dike #2. Sediment Trap #2 will need to be a sediment basin. Also, diversion dikes need to have sediment trapping measures at their outlet, diversion dike #2 and #4 outlet to nothing. Engineering recommends the following: Remove DD2 and DD4 Upgrade ST2 to a sediment basin and shrink STI Remove the pipe running from structure 22 to 23 in phases I and II ((show on phase III). Put in a temporary end section and very short pipe with proper culvert inlet protection running out of structure 22. Outlet the weir from STl into the culvert. (If a riser structure remains instead of a weir S", the sediment trap will need to be designed as a basin, regardless of whether or not more than 3 acres are draining to it.) Use natural existing contours to shape the basin. The proposed design for the basin shows filling in to make the basin, when leaving the existing contours would increase the storage of the basin and decrease the amount of earthwork needed. 11. (Revl) For phase I, at a minimum, some type of structure will be needed at 23. (As in comment 10, we recommend installing the pipe between 22 and 23 in phase III.) If the riser structure is to remain on the sediment trap, another possibility is to install the pipe running from the riser to 22 during phase II. Also, the note regarding converting the temporary riser measure to the permanent structure should include being converted upon approval of the E &S inspector. 12. (Revl) It appears that diversion dike #3 from phase 11 will be need to remain in place during parts of phase III. Please show DD3 on phase III of the plans, and revise the grading, inlet structures, and tree protection to leave enough room to keep DD3 on the plans. (At a minimum, a width of 5 feet is needed for the berm of diversion dikes. 13. (Revl) Please sign the conservation plan checklists on sheets 18 and 19.
