Revise the 2/1 windows on the north elevation to 1/1. Revise the elevations to show the proportion of the Gothic window in the north elevation that matches the rendering dated 9/8/09. Brick veneer should occur on the side of that gable as shown in the drawing Al submitted on the same date. Revise the landscape plan as follows: Add 2 -3 additional crape myrtles along the northwestern edge of the parking area Change the proposed Foster's holly to American holly Add 2 -3 more small clusters of ornamental deciduous trees along the EC Change the five dogwoods to little gem magnolias at 2" caliper. Page: 1.00 County of Albemarle Printed On: Tuesday, October 27, 2009 Page 1 of 1 Elizabeth Marotta From: Jonathan Rintels (jrintels @gmail.com] Sent: Friday, October 09, 2009 11:18 AM To:Bill Atwood Cc:Elizabeth Marotta Subject: From Jon Rintels re South Plains Church Hi Bill, I met with Elizabeth Marotta and reviewed the Sept 16 site plan for the church. I noticed that the arborvitae specified is not the Green Giant variety that we agreed to with the church and presented as the agreed upon planting at the Board of Supervisors meeting. The Green Giant variety is Thuja standishii x plicata. Instead, the site plan specifies Thuja occidentalis 'Techny' (also known as 'Mission'). This is described on the Internet as "the long - standing traditional cultivar that has dark green foliage year- round, to 12' tall by 4' wide, broadly pyramidal or upright oval in shape." http:// hcs. osu. edu/ hcs /TMI/Plantlist /th talis.html http _ / /www.westonnurseries.com/ index. efm? fuseactiol= plants.plantDetail &plant_id =986 The Green Giant arborvitae is fast growing and reaches 50 feet tall and eight feet wide. The Techny that is specified reaches only 12 -20 feet, is slow growing, and only 4 -6 feet wide. Thus, because of the lower elevation where these trees are to be planted, the arborvitae specified on the site plan doesn't help us at all. If the site plan were changed to specify the Green Giant arborvitae, as we agreed with the Church, then we would be willing to sign off on the staggered planting of the trees on the Church side of the property line as shown on the Sept. 16 site plan. I look forward to hearing from you on this.

The following comments are provided. A. SDP - 2009 -00080 Final Site Plan Comments 1. Engineering review recommends that the parking lot along Black Cat Road be modified to provide for one VDOT standard entrance. This is not a requirement due to a determination from the Chief of Current Development. 2. Please modify the grading in the western portion of the courtyard /garden so that the topography works with the raingarden/biofilter. 3. Please provide a detail for the sidewalk that meets or exceeds the county "s requirement of 4" of 3000psi concrete @ 28days and 4" of stone base beneath. [DM] B. WPO- 2009 -00050 Stormwater Management Plan Comments 1. A SWM facility maintenance agreement will need to be recorded before the site plan can be approved. Please submit this document with $17 fee directly to Ana Kilmer after consulting the guidelines available on the county website. 2. Please provide a modified simple removal rate spreadsheet for each drainage area /facility, not the whole site, which corresponds to drainage area lines drawn on the plan. This is necessary to confirm that each facility is sized appropriately for the watershed draining to it. 3. Please provide two permeability tests for the infiltration trench. The VMSH specifies that the in- situ permeability tests must yield infiltration rates greater that 0.52" per hour in order to consider infiltration facilities practical. The VSMH also states that the infiltration facility must drain in 48hours and the soil test must clearly show this. [VSMH 3.10] 4. On the infiltration trench detail, please specify that the depth is 3ft minimunz, the bottom of the trench is flat, and the #57 gravel is clean- washed. 5. Engineering review recommends removing the filter fabric from the infiltration trench and biofilter. Depending on the type used, the fabric could wind up being the limiting factor in both facilities. If the filter fabric is removed from the biofilter, it should be replaced with a 4" layer of pea gravel. If the filter fabric is to remain in the plan, I recommend specifying the product number. This is not a requirement. 6. The following modifications are required to the biofilter /rain garden detail: a. The depth of the biofilter mix must be 2.5ft. b. The thickness of the gravel layer must be between 12" and 18 ". c. The soil media must be called out as state approved mix. 7. Please provide a plan nag plan for the biofilter. There must be at lei( three species of shrub proposed. 8. Please provide the following note on sheets C1.1 and C3.1: When the stormwater management plan for Phase II is submitted, detention and stormwater quality computations will need to consider the pre - development condition as the property before the construction of the fellowship hall. 9. A SWM bond will be computed once the WPO plan is ready for approval. C. WPO- 2009 -00050 Erosion and Sediment Control Plan Comments 1. Please add to the set the County's standard ESC notes. These notes can be found in the design manual, available online. 2. The limits of construction areas should be connected. 3. Please add Dust Control (DC) to the plan. 4. Please provide silt fence on the north side from the treeline of the 9" spruce to the midpoint between the 9'" Holly and the 9" Dogwood. 5. Tree protection is being shown throughout the site but the tree layer has been turned off. Please show the dripline of all trees on the ESC plan. Construction cannot be shown within the dripline of trees required to be protected. This rule appears to have been violated in the garden /courtyard and adjacent to the fill area. To rectify this, the grading of the courtyard can be modified to keep fill out of the dripline of the cherry and dogwood trees or tree wells can be provided. Regarding the fill area, I recommend moving it to the northern border because fill will likely be necessary to construct the parking lot in Phase H at the minimum parking lot grade of 5 %. (The area of fill was also shown outside the limits of work on the approved SP plan and may require a determination from the Zoning Administrator if the applicant wishes to continue to propose fill in this location.) Please remove grading from within the dripline of 12'" Holly. Also, please move the infiltration trench to the south as much as possible out of the roots of the 27'" Gum. For all other areas showing the limits of construction within the dripline of tree, please provide a letter from a certified arborist attesting that the latest revision of the site/ESC plan would not compromise the health of any tree shown with construction within its dripline. 6. Please demonstrate that this development meets VESCH Minimum Standard 19 regarding adequate channels. 7. An ESC bond will be computed once the WPO plan is ready for approval.

It is my understanding that phase 1 of the project will build a new fellowship hall and not increase the projected traffic and phase II will rebuild the entrance as I have commented previously on. It will be acceptable to phase this project and have the entrance upgraded when the parking lot is rebuilt. I had a chance to quickly look at the parking and entrance plan and I did have some concerns with the layout. I ask that you be sure to include me in the review of the entrance at the time the phase 11 plan is submitted. Thanks Joel Joel DeNunzio, P.E.

Main St., Suite 100 Charlottesville, VA 22902 RE: ARB200900052 South Plains Presbyterian Church Dear Ms. Cooper; The Albemarle County Architectural Review Board reviewed the above noted item at its meeting on Monday, October 19, 2009. The Board voted to grant approval of the Certificate of Appropriateness, subject to the following conditions: 1. Revise the location of the 1/1 windows within the arched recessed areas along the elevation so that they are centered, and therefore, more coordinated with the architectural elements in which they are placed. 2. Revise the 2/1 windows on the north elevation to 1/1. 3. Revise the elevations to show the proportion of the Gothic window in the north elevation that matches the rendering dated 9/8/09. Brick veneer should occur on the side of that gable as shown in the drawing Al submitted on the same date. 4. Revise the landscape plan as follows: Add 2 -3 additional crape myrtles along the northwestern edge of the parking area Change the proposed Foster's holly to American holly Add 2 -3 more small clusters of ornamental deciduous trees along the EC Change the five dogwoods to little gem magnolias at 2" caliper. You may consider this letter your Certificate of Appropriateness. This approval is predicated on the fact that the design and materials, as proposed and exhibited for review, will be used. The acceptance of approval implies that the applicant has agreed to execute the design as indicated on the site plan, attachments, materials, samples, and other submittal items presented. Any change in the approved design or materials will require an amendment to the plan and must be reviewed and approved by the Architectural Review Board. Please note that this application is approved with the condition that mechanical equipment shall not be visible from the Entrance Corridor. Please note the following: 1. This application is approved with the condition that mechanical equipment shall not be visible from the Entrance Corridor. 2. Changes made to the site or architectural plans after issuance of a Certificate of Appropriateness can delay the signing of mylars and the approval of building permits. It is in the applicant's best interest to notify ARB staff of such changes and to initiate the review of amendments to ARB- approved plans to avoid future delays. If you have any questions, please do not hesitate to contact me.

The following comments are provided. A. SDP - 2009 -00080 Final Site Plan Comments B. WPO -2009 -00050 Stormwater Management Plan Comments 1. A SWM facility maintenance agreement will need to be recorded before the site plan can be approved. Please submit this document with $17 fee directly to Ana Kilmer after consulting the guidelines available on the county website. Rev. 1) Comment has not been addressed. 2. Please provide a modified simple removal rate spreadsheet for each drainage area/facility, not the whole site, which corresponds to drainage area lines drawn on the plan. This is necessary to confirm that each facility is sized appropriately for the watershed draining to it. Rev. 1) Using the information given in the existing plans, I have generated a modified simple spreadsheet for each BMP (please see the documents accompanying this comment letter). Both facilities require n 65% removal rate. To achieve a 65% removal rate, the infiltration trench must store 512cf (1" over specified impervious area). The biofilter bed is sized appropriately to achieve a 65% removal rate using the state's 5% of the impervious area guidelines. However, this method assumes that the depth of the biofilter ponding is 1 ft. Please provide 1 ft ofponding or double the size of the facility. 3. Please provide two permeability tests for the infiltration trench. The VMSH specifies that the in- situ permeability tests must yield infiltration rates greater that 0.52'" per hour in order to consider infiltration facilities practical. The VSMH also states that the infiltration facility must drain in 48hours and the soil test must clearly show this. [VSMH 3.10] Rev. I) Comment has not been addressed. The infiltration tests must be provided before plan approval because the results will dictate the geometry of the futility. The maximum depth equation that should be used for the infiltration facility should be 3.10 -5 from the VSMH, where f, is half the measured infiltration rate (which must be greater than 0.52 in /hr). For example, assuming an infiltration rate of 0.52 in /hr is found on site, the maximum depth of the facility will be 31.2 inches which would require the footprint to be noticeably larger. If soil tests are not performed at this tinge, please design this fricility as a biofilter now. Then, if during construction tests find the soil to be within the adequate range for infiltration practices, you may submit a SWM amendment for the installation of an infiltration trench. 6. The following modifications are required to the biofilter /rain garden detail: c. The soil media must be called out as state approved mix. Rev. 1) Comment has not been addressed Remove the specification ofLuckstone Mix. 9. A SWM bond will be computed once the WPO plan is ready for approval. Rev. 1) Comment remains' unchanged C. WPO- 2009 -00050 Erosion and Sediment Control Plan Comments 5. Tree protection is being shown throughout the site but the tree layer has been turned off. Please show the dripline of all trees on the ESC plan. Construction cannot be shown within the dripline of trees required to be protected. This rule appears to have been violated in the garden /courtyard and adjacent to the fill area. To rectify this, the grading of the courtyard can be modified to keep fill out of the dripline of the cherry and dogwood trees or tree wells can be provided. Regarding the fill area, I recommend moving it to the northern border because fill will likely be necessary to construct the parking lot in Phase I1 at the minimum parking lot grade of 5 %. (The area of fill was also shown outside the limits of work on the approved SP plan and array require a determination from the Zoning Administrator if the applicant wishes to continue to propose fill in this location.) Please remove grading from within the dripline of 12"' Holly. Also, please move the infiltration trench to the south as much as possible out of the roots of the 27" Gum. For all other areas showing the limits of construction within the dripline of tree, please provide a letter from a certified arborist attesting that the latest revision of the site /ESC plan would not compromise the health of any tree shown with construction within its dripline. Rev. 1) Please show all driplines on the Erosion and Sediment control plan. The letter, from the certified arborist is acceptable. If damage to any tree shown as being protected in the approved SP plan is suffered, a zoning violation will be pursued. 6. Please demonstrate that this development meets VESCH Minimum Standard 19 regarding adequate channels. Rev. 1) MS -19 requirements apply to the outfall from the culvert to the stream. MS -19 regulates downstream channels, which doesn't necessarily mean offsite drainways. However, after the drainage area to this culvert has been graphically demonstrated by the applicant, the county with withdraw this comment because of the low peak discharges if outlet protection is specified on the plan. The length, width, and stone size tithe outlet protection should he called out on the plan. MS -19 will be a larger concern in Phase II of this project. 7. An ESC bond will be computed once the WPO plan is ready for approval. Rev. 1) Comment remains unchanged. 8. Rev. 1)The construction sequence on the cover sheet refers to an area on the plan where waste from the foundation excavation will be placed. However, I could not find its location in either the site plan or ESC sets. It appears that this notation should be removed because it conflicts with the direction given to the contractor in the narrative. ILL / o ~$fflr„ il(111•.,, eft COUNTY OF ALBEMARLE Department of Community Development 401 McIntire Road Charlottesville, Virginia 22902 -4596 Phone (434) 296 -5832 Fax (434) 972 -4126 Project:South Plains Presbyterian Church: WPO- 2009 - 0000; SDP -2009 -00080 Plan preparer:Mr. Bill Atwood; Atwood Architects Ms. Ashley Cooper; Cooper Planning Mr. Clark Gathwright; Daggett and Griggs Architects Owner or rep.:South Plains Presbyterian Church Date received:23 September 2009 Rev. 1) 25 November 2009 Date of Comment: 13 October 2009 ReY: I) —1 December 2009 Engineer:7; Phil Custer The second submittal of the final site, ESC, and SWM plan for South Plains Presbyterian Church has been reviewed. The following comments are provided. A. SDP - 2009 -00080 Final Site Plan Comments B. RO- 2009 -00050 Stormwater Management Plan Comments Pe V a ( 1. A SWM facility maintenance agreement will need to be recorded before the site plan can be Z /I approved. Please submit this document with $1 7 fee directly to Ana Kilmer after consulting the nt.(,t -I riry guidelines available on the county website. 1 Rev. 1) Comment has not been addressed. et-- 2. Please provide a modified simple removal rate spreadsheet for each drainage area/facility, not the f (1 Ott whole site, which corresponds to drainage area lines drawn on the plan. This is necessary to confirm that each facility is sized appropriately for the watershed draining to it. Rev. 1) Using the information given in the existing plans, I have generated a modified simple spreadsheet for each BMP (please see the documents accompanying this comment letter). Both facilities require a 65% removal rate. To achieve a 65% removal rate, the infiltration trench must store 512cf (1" over specified impervious area). The biofilter bed is sized appropriately to achieve a 65% removal rate using the state's 5% of the impervious area guidelines. However, this method assumes that the depth of the biofilter ponding is lft. Please provide l ft ofponding or double the size of the facility. 3. Please provide two permeability tests for the infiltration trench. The VMSH specifies that the in- situ permeability tests must yield infiltration rates greater that 0.52" per hour in order to consider infiltration facilities practical. The VSMH also states that the infiltration facility must drain in 48hours and the soil test must clearly show this. [VSMH 3.10] Rev. 1) Comment has not been addressed. The infiltration tests must be provided before plan approval because the results will dictate the geometry of the facility. The maximum depth equation that should be used for the infiltration facility should be 3.10 -5 from the VSMH, where f is half the measured infiltration rate (which must be greater than 0.52 in /hr). For example, assuming an infiltration rate of 0.52 in/hr is found on site, the maximum depth (tithe facility will be 31.2 inches which would require the footprint to be noticeably larger. If soil tests are not performed at this tine, please design this facility as a biofilter now. Then, if during construction tests find the soil to be within the adequate range for infiltration practices, you may submit a SWM amendment for the installation of an infiltration trench. 6. The following modifications are required to the biofilter /rain garden detail: c. The soil media must be called out as state approved mix. Rev. 1) Comment has not been addressed. Remove the specification of Luckstone Mix. 9. A SWM bond will be computed once the WPO plan is ready for approval. Rev. 1) Comment remains unchanged C. WPO- 2009 -00050 Erosion and Sediment Control Plan Comments 5. Tree protection is being shown throughout the site but the tree layer has been turned off. Please show the dripline of all trees on the ESC plan. Construction cannot be shown within the dripline of trees required to he protected. This rule appears to have been violated in the garden /courtyard and adjacent to the fill area. To rectify this, the grading of the courtyard can be modified to keep fill out of the dripline of the cherry and dogwood trees or tree wells can be provided. Regarding the fill area, I recommend moving it to the northern border because fill will likely be necessary to construct the parking lot in Phase II at the minimum parking lot grade of 5 %. (The area of fill was also shown outside the limits of work on the approved SP plan and may require a determination from the Zoning Administrator if the applicant wishes to continue to propose fill in this location.) Please remove grading from within the dripline of 12" Holly. Also, please move the infiltration trench to the south as much as possible out of the roots of the 27 Gum. For all other areas showing the limits of construction within the dripline of tree, please provide a letter from a certified arborist attesting that the latest revision of the site /ESC plan would not compromise the health of any tree shown with construction within its dripline. Rev. 1) Please slow all driplines on the Erosion and Sediment control plan. The letter from the certified arborist is acceptable. If damage to any tree shown as being protected in the approved SP plan is suffered, a zoning violation will be pursued. 6. Please demonstrate that this development meets VESCH Minimum Standard 19 regarding adequate channels. Rev. 1) MS -19 requirements apply to the outfall from the culvert to the stream. MS -19 regulates downstream channels, which doesn't necessarily mean offsite drainways. However, after the drainage area to this culvert has been graphically demonstrated by the applicant, the county with withdraw this comment because of the low peak discharges if outlet protection is specified on the plan. The length, width, and stone size of the outlet protection should be called out on the plan. MS -19 will be a larger concern in Phase II of this project. 7. An ESC bond will be computed once the WPO plan is ready for approval. Rev. I) Comment remains unchanged. 8. Rev. 1)The construction sequence on the cover sheet refers to an area on the plan where waste from the foundation excavation will be placed. However, I could not fund its location in either the site plan or ESC sets. It appears that this notation should be removed because it conflicts with the direction given to the contractor in the narrative.

All comments regarding the ESC plan have been addressed and the ESC plan is hereby approved pending site plan approval. The SWM plan can be approved after the following minor changes are made: Increase the footprint of the infiltration trench by 18% and update the infiltration calculations with the data from the soil tests (the impervious area draining to this facility is 7247sf, not 6140sf). Also, the callout on sheet C3.1 specifies a footprint of 160sf and should be corrected. Label the set on the Cover Sheet as Erosion and Sediment Control and Stormwater Management Plans The professional seal must be signed and dated. Remove the soil test note on the infiltration trench detail on sheet 3.2 (this is only a recommendation because another soil test is not required) Once these changes have been made, please submit 5 copies of the plans for approval. Another $300 review fee is not warranted. The ESC bond has been computed to be $8,800. The SWM bond has been computed to be $3,600.
