(The following comments are those that have been identified at this time. Additional comments or conditions may be added or eliminated based on further review.) [Each comment is preceded by the applicable reference to the Albemarle County Code.] Applicable Comments from Initial Site Plan Action Letter (February 7, 2020): 1. [ZMA200100015]: The development appears to be in general accord with the approved ZMA-2001-00015 (including Exhibit B — Application Plan, sheets API-AP6): the residential use and number of dwelling units are in general accord with what is shown as Parcel I containing 250 residential units on AP-4; and the open space, trails, and pedestrian connectivity are in general accord with what is shown as Parcel J on AP-4 and AP-5, and as Anticipated Pedestrian Route — Connection to Gateway on AP-6. First submittal: Per proffer #4 of ZMA2001-15. reasonable Dedestrian access needs to be Drovided through the site down to the Countv owned ereenway. A 10' Class A asphalt path has been provided at the southern end of the development down to the erg enway. It appears that the path goes onto TMP 07800-00-00-020M1 which is owned by Worrell Land & Development Company LC. Please address the following: an easement over the 10' wide pedestrian path should be provided, owners of TMP the applicant is working with the owner of TMP 78-20M1 to prepare a boundary line adjustment, land reservation plat to obtain acreage from TMP 78-20M1 to incorporate into TMP 78-20M5. This will create a connected area of land from Peter Jefferson Pkwy to the existing Co"greenwaysystem adjacent to the river. This plat will be submitted to the County for review, approval, and recordation prior to final site plan approval. 3'" Submittal: SUB2020000130 has been submitted which shows the new easement. Once that plat is recorded, please update the site Dian so that the easement labels state the recorded instrument deed book and Dade on all applicable drawings. Additionally. staff acknowledges that the apDlicant has Drovided a 5' sidewalk through the site to access the 10' path. Staff with CDD and the Parks & Rec Department have evaluated the proposed pedestrian route through the site. See comment #3 from Parks & Recreation staff below. Several options are available that can be done on revised plans to accomplish the proffer's intent for providing reasonable access to the regr enway. This could include one or more of the following options (or a combination thereof): a. Providing a publicly -accessible trail connection (Class A shared use path: 10' wide / asphalt surface) through the property on the west side of the proposed private travel may. connecting to sidewalk along Peter Jefferson Parkway; and/or b. Revising the proposed private on -street pedestrian facilities (5' sidewalk) along the proposed private travel way to instead be a Class A shared use path (10' wide / asphalt surface) and providing a public use access easement: and/or C. Adjusting the —4.5-acre "special lot' to increase in size, so as to contain additional acreage to the west of the proposed private street, in order to create more opportunity/flexibility to install a public bike/ped connection through this physically constrained area that contains substantial steep slopes. A public access easement will need to be provided through the site over the pathway. Please see comment #3 under "New Comments Final Site Plan" section below for more information regarding the easement. 21 submittal: Please provide a variable width public access and use easement ex licitly for public bike/ped use) over one of the proposed travelways and over a portion of the proposed sidewalks on the Presidio property (TMP #78-20M6). Such an easement will ensure that members of the public will have reasonable access between the Peter Jefferson Parkway public right of way and the Rivanna Greenway property owned by the County prior to County construction of a shared use path (or other type of recreational connection) within the Presidio Special Lot (TMP #78-20M5). Specifically, in order to ensure that the proposed development `will provide reasonable provisions for access to the Greenway System" concurrent with the commencement of the proposed use(ss). See Parks & Rec. comment for description of requested easement locations inside of the Presidio site. 31 Submittal: SUB2020000130 has been submitted which shows the new easement. Once that plat is recorded, please update the site plan so that the easement labels state the recorded instrument deed book and pace on all applicable drawings. 2. [Section 32.5.2(a)]: The title on the Cover Sheet (Sheet IA) incorrectly states that this application is a "Final Site Plan." This application has been submitted, processed, and reviewed as an "Initial Site Plan." First submittal: Comment no longer applicable. 3. [Section 32.5.2(a)]: If the Open Space contained in the recently -created Special Lot (approximately 4.5 acres, identified as Tax Map/Parcel #78-20M5) is included in the calculations for this site plan, then please add this Tax Map/Parcel number and acreage to the "Tax Map No." and "Total Project Area" information in the General Notes on the Cover Sheet (Sheet IA). Please also correct any density calculations that may change based on revisions to the project area acreage. First submittal: Comment addressed. Only TMP 07800-00-00-020M6 is included in the acreage. 4. [Z.O. Section 32.5.2(a)]: Please identify Tax Map/Parcel #78-20M5 on the Overall Layout Sheet (Sheet 3) and include a note identifying it as Open Space reserved for future dedication to the County for public use. First submittal: Comment addressed. 5. [Z.O. Section 32.5.2(i), (j), (k), (1)1: Please ensure all existing and all proposed public and private easements are shown and labeled. First submittal: Comment not fully addressed. There is a conservation easement recorded in DB 2544, pages 243-251 that appears to now be located within both TMP 78-20M5 and 78-20M6. Please show this easement on the plans. Per the restrictions in the recorded instrument, limited activities may occur within that easement. Please provide a written response verifying that the applicant and owner have researched this and that the proposed site development complies with the restrictive covenants. Refer to DB 2607 PG 572-575 for other easements to which the property may be subject and show those easements that are located within TMP 78-20M6. 2°d submittal: Comment addressed. 6. [Z.O. Section 32.5.2(i), 0), (k), (1)1: Please ensure Deed Book/Page references are included for existing easements. First submittal: See comment #5, add DB/page references for existing easements. 2"d submittal: Two easement plats, SUB202000089 and SUB202000115, are currently under review and will create new easements associated with the project. These must be approved and recorded prior to final site plan approval. Once these easements are recorded, Please update the site plan so that all deed book and page numbers for recorded instruments are updated. 7. [Z.O. Sections 32.5.2(a), (b), (n), and (s)]: Please ensure that all portions of the subject property are included on each applicable Sheet. Staff acknowledges the Match lines on Sheets 2 and 3 (shown at a scale of 1' = 50'). However, other sheets (shown at a scale of 1" = 30') do not include all portions of the subject property; for example, the Layout Plan (Sheets 4 and 5), the Utility Plan (Sheets 6 and 7), and the Grading & Drainage Plan (Sheets 8 and 9) exclude the northwestern and southwestern portions of the property. First submittal: Comment addressed. 8. [Z.O. Sections 32.7.2.3 and 4.12.61: (Advisory Review Comment) — Based on the proposed number and types of units, a minimum of 425 parking spaces are required. Staff acknowledges that the "Parking Required" and "Parking Provided" sections of the "General Notes" on the Cover Sheet (Sheet IA) indicate that 426 spaces are provided, including 406 surface parking spaces and 20 garage spaces. Staff further acknowledges that 14 parking spaces appear to provide universal access towards meeting ADA requirements. First submittal: See comment #1 under the "New Comments Final Site Plan' section below. 9. [Z.O. Section 32.7.2.31: (Advisory Review Comment) — Staff acknowledges that a 5' wide concrete sidewalk is proposed in multiple locations throughout the development, including along Peter Jefferson Parkway between the (proposed) eastern entrance and the northwestern property boundary, in order to establish a safe and convenient pedestrian connection to adjoining properties and adjacent employment centers. Please note that this connection must be designed and constructed to the standards established in the Albemarle County Design Standards Manual, provided that all ramps for persons with mobility impairments shall be designed and constructed to the standards of VDOT. First submittal: Comment addressed pending confirmation from Engineering Division staff. 2nd submittal: Comment addressed. 10. [Z.O. Section 32.7.2.31: (Advisory Review Comment) — Staff acknowledges that a direct "pedestrian walkway" or pedestrian connection is proposed across Peter Jefferson Parkway, in order to enable safe, convenient pedestrian access between the subject property and the Martha Jefferson Hospital property. Please note that this connection must be designed and constructed to the standards established in the Albemarle County Design Standards Manual, provided that all ramps for persons with mobility impairments shall be designed and constructed to the standards of VDOT. Please also note that this proposed "pedestrian walkway" or pedestrian connection is subject to VDOT acceptance of a "justification report" as outlined in previous review comments provided by Mr. Adam Moore, PE (dated 5/16/2018). Community Development staff remain available to assist with the coordination of this "pedestrian walkway" at an unsignalized location. And CDD staff strongly support this proposed pedestrian crossing at an unsignalized location in order to: a.) proactively address the likelihood of frequent pedestrian crossings of Peter Jefferson Parkway at a location that would otherwise be unprotected and unsafe, and b.) to facilitate safe, convenient pedestrian mobility between places of residence and a major place of employment. More specifically, it can be reasonably anticipated that a relatively large number of pedestrian trips will occur on a daily basis between the two hundred fifty (250) dwelling units and Martha Jefferson Hospital. Even factoring in the provision of a new sidewalk along Peter Jefferson Parkway (as required pursuant to Zoning Ordinance §32.7.2.3, and as acknowledged above in Planner review comment #9), if no such pedestrian walkway is provided across Peter Jefferson Parkway then residents of the proposed apartment complex who want to walk from the apartments to the hospital would have to choose to walk approximately 3,000 linear feet on sidewalks, crosswalks, and walking paths in order to safely access the hospital — and would have to choose not to exit the development, cross Peter Jefferson Parkway (without any safe pedestrian infrastructure), and access the hospital via a much more direct route that is approximately 550 linear feet in length. A diagrammatic exhibit illustrating this issue is provided with this SRC review comment letter packet for reference. First submittal: Comment addressed. see VDOT comment letter. 11. [Z.O. Sections 32.7.2.3 and 25A.51: Staff acknowledges the provision of safe, convenient on -site pedestrian connections in many locations throughout this proposed development. However, staff have identified strategically important locations where additional safe and convenient on -site pedestrian connections are necessary. These connections must be designed and constructed to the standards established in the Albemarle County Design Standards Manual, provided that all ramps for persons with mobility impairments shall be designed and constructed to the standards of VDOT. Specifically, such safe, convenient pedestrian connections are required in the following general locations, as described below (listed a-d) and as conceptually shown below (in pink): / INPI / / 0 _ \ \ A G (PL /� NPI ITVP) \ LSR os (TYP) N� \I \ \ �p,� ✓ ITYPI IV CLUBHOUSE \ ) Ge \ !

First submittal: Comment addressed. 12. [Z.O. Section 32.5.2(b)]: Please revise the sub -heading for the "Critical Slopes" section within the General Notes on the Cover Sheet (Sheet 1A) to "Steep Slopes Overlay District." Technically, there are no "Critical Slopes" within the Development Area; and Steep Slopes are technically an overlay zoning district. First submittal: Comment addressed. 13. [Z.O. Section 32.5.2(n)]: Show the proposed location(s) of outdoor trash containers. Staff acknowledges that the "Trash Receptacles" section within the General Notes on the Cover Sheet (Sheet 1A) references the proposed provision of a dumpster and trash compacter. Please also provide additional waste and recycling containers in the developed recreation areas and within other areas of the proposed development and show these on the final site plan. First submittal: Comment not fully addressed. As shown on the plans_ the concrete nad at the trash receptacle area does not extend at least 8' beyond the front of the dumpster, as required under Section 4.12.19 M. Please draw a concrete pad extending at least 8' beyond the front of the dumpster on all applicable sheets. Additionally, no screening details have been provided, as required by Section 32.7.9.7 (a)(3). Please either provide landscaping or a constructed screen around the trash receptacle area. If a wall or fence will be provided, please provide a cut sheet detail of the fence/wall in dumpster pad and enclosure on Sheets 3 and 5 so that it states "brick enclosure shall be at least 6' in height." 3' Submittal: Comment addressed. 14. [Z.O. Section 32.5.2(n)]: Show the proposed location(s) of outdoor lighting. Staff acknowledge that the "Lighting" section within the General Notes on the Cover Sheet (Sheet 1A) indicates that "Parking lot and building lighting is included with this final site plan." However, no such lighting information appears to be provided. Please note that a Lighting Plan that demonstrates compliance with Z.O. Sections 32.6.21 and 4.17 is required with the Final Site Plan application. First submittal: See comment #2 under the "New Comments Final Site Plan" section below. Additionally, because the subject property is within the Entrance Corridor Overlay District, this proposed project (including the Lighting Plan) is subject to review by the Architectural Review Board (ARB) and ARB staff, and approval/issuance of a Certificate of Appropriateness by the ARB is required. Staff acknowledges that application ARB-2019-00145 was submitted for review on 11/25/2019, and was then deferred indefinitely by the applicant(s) on 12/30/2019. First submittal: See comment #2 under the "New Comments Final Site Plan" section below. 4 15. [Z.O. Section 32.5.2(p)]: Staff acknowledges the Landscape Plan sheets (Sheets 12, 13, and 14).Because the subject property is within the Entrance Corridor Overlay District, this proposed project (including the Landscape Plan) is subject to review by the Architectural Review Board (ARB) and ARB staff, and approval/issuance of a Certificate of Appropriateness by the ARB is required. Staff acknowledges that application ARB-2019-00145 was submitted for review on 11/25/2019, and was then deferred indefinitely by the applicant(s) on 12/30/2019. First submittal: See ARB comments below. Once the ARB has issued a COA, this comment will be addressed. The plan is tentatively scheduled to go to the ARB in May. 2°d submittal: Comment addressed. ARB has approved the site plan, see APB comments below. 16. [Z.O. Sections 32.5.2(n) and 4.16]: The proposed development does not contain all of the required developed recreation areas and minimum facilities. Specifically, Z.O.4.16.2 ("Minimum Facilities") requires the following: a. Z.O. 4.16.2.1: One (1) tot lot (2,000 SF minimum) shall be provided for the first thirty (30) units and for each additional fifty (50) units. First submittal: Comment was informationaL b. As applied to SDP201900075: (250 units = Five (5) tot lots / minimum 10,000 SF total; see 4.16.2.1 for full details of this requirement). First submittal: Comment was informational. c. Z.O. 4.16.2.2: One-half (1/2) court for basketball shall be provided for each one hundred (100) units. First submittal: Comment was informational. d. As applied to SDP201800018: (250 units = Two (2) half -courts or one (1) full -court; see 4.16.2.2 for full details of this requirement). First submittal: Comment was informational. However, pursuant to Z.O.4.16, the planning director has some discretionary authority to consider proposed substitutions for the facilities that are required by this section of the Zoning Ordinance. The proposed provision of "trails/walking paths" which "shall be available for public use to access the Rivanna River trails" in lieu of some of the minimum required facilities would likely be partially acceptable and partially unacceptable. Please revise as follows: A. Provide the correct calculations (SF) of the required recreation facilities (info summarized above) by revising the "Recreation" section within the "General Notes" on the Cover Sheet (Sheet IA). First submittal: Comment addressed. B. Clarify the proposed recreation facilities; the General Notes on the Cover Sheet (Sheet IA) indicate that the proposed total area for recreation would be 51,200 SF (in the "Recreation" section), but the General Notes also indicate that the recreational areas equal 0.83 acres (in the "Land Area" section). First submittal: Comment addressed. C. Provide a recreation facilities proposal for review by the Planning Director and Chief of Planning that includes the calculations requested in comments # 14-A, and which describes any and all requested substitutions from the required minimum facilities (such as trails/walking paths, clubhouse and pool, dog park, etc.) with supporting explanations/rationale. First submittal: The plan has been updated to show the proposed recreational substitutions. However, a formal written request letter must be submitted so that it can be forwarded to the Planning Director for review. Include the require recreation calculations, and provide the proposed recreation area calculations and a description of the facilities themselves (for example, indicate what, if any, improvements will be provided within the beer garden and courtyards. Explain whether any fitness equipment or exercise areas are included in the 14,000 sq. ft. clubhouse). Also, is the 9.600 sq. ft. area figure of the walking trail the area within the dashed lines_ as shown on Sheets 3 & 5? Is the dashed line supposed to represent an access easement? 2' submittal: Formal substitution request has been received. The proposed substitutions meet the minimum area requirements of Section 18-4.16.1. However, additional details are needed regarding how the proposed substitutions are equivalent to the minimum facilities specified by Section 18-4.16.2. Please provide additional clarification about the types of facilities/equipment that are proposed in the 12,650 sq.ft. active recreation courtyard. Is this area just goingto o be grassed? Per Section 18-4.16.2.1_ substitution requests can be approved provided that proposed equipment and facilities "are appropriate to the needs of the occupants." Based on the description of the recreational areas in the substitution request, it appears that no tot lot equipment is provided at all, as required by Section 4.16.2.1. Since multifamily dwelling residents typically include younger children, staff can support the substitution request if the minimum facilities required for one (1) tot lot are provided on the site plan. Please provide a response and update the substitution request/site plan as necessary. Staff suggests converting the proposed beer garden into a tot lot that contains the facilities as described in Section 18-4.16.2.1. Cut -sheets of playground equipment will need to be provided on the construction detail sheets. 3'd Submittal: Comment addressed. Charles Rapp. Director of Plannin¢, has approved the recreational facility substitution request. No tot lots are needed. D. Please review the proposed locations, alignments, material specifications, and "Classification" of the "proposed primitive trail way," and any other proposed or potential trail or park infrastructure, in collaboration with Mr. Dan Mahon in the Albemarle County Parks & Recreation Department (ACPR). First submittal: A callout on Sheet 5 states that there is a gate on the path and to refer to the detail on Sheet 10. No gate detail is provided on Sheet 10. Please verify whether a gate is proposed, and the purpose for the gate. 2°" submittal: Gate has been removed from Sheet 5, comment addressed. As stated in comment #1 above, staff is requesting revisions to the proposed public access. If the 5' sidewalk on the east side of the western travel way will be converted to a 10' wide Class A asphalt path throughout the site up to Peter Jefferson Parkway, this comment will be addressed. If the applicant chooses one of the other options mentioned in comment #1, staff will review this on a future submittal to verify whether it provides reasonable access. 21 submittal: Public access proposal has been revised since first submittal after conversations between the applicant and Parks & Recreation staff. Applicant proposes to reserve land on TMPs 78-20M1 and 78-20M5 for future dedication to public use so that a trail system can be built by the County in the future to enable access to the existing greenM, Wr ZMA2001-15. Please provide a variable width public access and use easement ex licitly for public bike/ped use, over an internal travelway and sidewalk on the Presidio property (TMP #78-20M6). Such an easement will ensure that members of the public will have reasonable access between the Peter Jefferson Parkwakpublic right of may and the Rivanna Greenway property owned by the County prior to County construction of a shared use path (or other type of recreational connection) within the Presidio Special Lot (TMP #78-20M5). Specifically, in order to ensure that the proposed development "will provide reasonable provisions for access to the Greenway System" concurrent with the commencement of the proposed use(ss). See Parks & Rec. comment for description of requested easement locations inside of the Presidio site. 31 Submittal: SUB2020000130 has been submitted which shows the new easement. Once that plat is recorded, please update the site plan so that the easement labels state the recorded instrument deed book and pace on all applicable drawin¢s. Furthermore, please revise the callout on Sheet 13 for the trail. It states that it will be gravel. 2°" submittal: Comment addressed, labels have been updated to state that the trail will be a 10' Class -A Type 1 low maintenance asphalt trail. 17. [Z.O. Sections 32.5.2(b) and 32.5.2(i)]: In consideration of this subject property's strategic location relative to the Rivanna River, the Old Mills Trail, and the County's Rivanna Greenway and Blueway System, and following the extensive coordination between the applicant team and County staff in 2019, CDD-Planning staff believe additional coordination with Mr. Dan Mahon in ACPR is necessary. The purpose of this additional coordination would be to revisit the previous collaborative efforts related to park planning and trail planning efforts, and to review and (potentially) refine the proposed public access and publicly -accessible amenities that are shown and annotated on this site plan. a. Please note that ACPR staff have provided written review comments (dated 1/17/2020), which are attached to this comment letter. Please also note that Mr. Mahon intends to attend the 1/23 SRC meeting to represent ACPR and discuss these issues with the applicant team in person. First submittal: If the 10' wide Class A asphalt path is provided through the site and a new public access easement is provided over the path on both TMPs 07800-00-00-020M1 and 07800-00-00-020M6 as mentioned in comment #1, comment #16, this comment will be addressed. Otherwise, staff from CDD and Parks & Recreation will need to revisit this with the applicant to ensure that reasonable access is provided, per proffer #4 of ZMA2001-15.2nd submittal: Public access proposal has been revised since first submittal after conversations between the applicant and Parks & Recreation staff. Applicant proposes to reserve land on TMPs 78-20M1 and 78-20M5 for future dedication to public use so that a trail system can be built by the County in the future to enable access to the existing erg enwayper ZMA2001-15.

PIP - Peter Jefferson Parkway (Ex.) ACDSM -Albemarle County Design Standards Manual Note: Engineering is grateful for Applicant's immediate written response (1/23/2020 10:42 PM), which reflects sincere interest in limiting comments effect on ISP approval. That Collins Engineering (CE) affords chance to revise comments prior to expanding audience is considerate. Comments relating to guardrail along PIP, review errors, are withdrawn. CE coordinated with VDOT on this (and other projects), and reports slopes graded 3:1 or flatter do not require guardrail (grayscale ikethFetlg :.) Discussion with CE may help resolve line work comments. CG-6 (with gutter) for concentrated runoff in parking areas and travelways is the expectation. CG-2 is fine for high side of parking areas. Appleton Way must meet VDOT Road Design Manual and county code requirements (CG-6 on both sides of the travelway). Parking areas must meet county code requirements. Since this is a site plan, requirements listed at 18-4, 18-32, and Ch. 14 apply to various degree. ACDSM applies. Review errs in stating storm pipe grade of 0.50.0.52. and 0.53%, may not be approved. They can be. Albemarle, having revised review to recommend increase in slope (0.60%) may take skeptical stance concerning any pipe at any depth installed at less than county stone pipe min. slope. Initial comment should have recommended conservative design. As -built drawings routinely reveal pipes (designed at 0.50%) installed at <0.50%, which may lead to failure and expense to remedy. 25 comments identified objectionable are highlighted red. A portion are withdrawn (grayscale/^�-"�..,, ed o"---e :), a portion maybe revised after discussion. Comment 4 is withdrawn provided Engineering Review Comments Page 2 of 12 the ISP plan explicitly states topographic survey performed in support of design meets state code requirements for surveys; otherwise, Albemarle has insufficient information at this point, and cannot assume an aerial survey meets state code. Given this, no comment imperils initial site plan approval from Engineering perspective. Comment #4 has been discussed internally, and Engineering anticipates written response from a licensed surveyor. Engineering is appreciative of thoughtful Applicant response. Misplaced review comments place a burden on Applicants that we hope to avoid. Review errors relate to: guardrail along PIP, inadequate research of suitability of HDPE pipe (permissible to use), and to possible misunderstandings. We regret mistakes. In one day, CE revised ISP in response to comments. Albemarle commends remarkable response. Engineering has not reviewed revisions, but revisions address many comments, now shown in light grayscale. (These will be checked with plan re -submittal.) * Comments relating to guardrail (PJP), prompted by safety concerns, are withdrawn. Request for guardrail along the entire west side of Appleton Street (design relies on retaining walls and slopes steeper than 3:1 above unrecoverable slopes), addressed. Sheet 1-A 1.

Topo and survey: Aerial survey performed by Virginia Resource Mapping dated January 2006 (with field verification by Collins Engineering, August 2019) is insufficient basis of design. Engineering recommends Applicant contact GIS /Ruth Emerick to discuss this review comment. Note: Ms. Emerick anticipates extended leave in the near future. Until an acceptable source of topography is basis of design, Engineering recommends disapproval of ISP, and resubmittal of ISP with acceptable basis of topographic design. (Rev) Comment revised. Ref. JA email to Applicant January 24, 2020 10:50 AM), also, please see above. Comment 4 is withdrawn once ISP plan explicitly states topographic survey performed in support of design meets state code requirements for surveys, otherwise, Albemarle has insufficient information (at this point) and does not assume that aerial survey meets state code. Given this, no comment imperils initial site plan approval from Engineering perspective. Comment 44 was reviewed, internally. Please provide a written certification from licensed surveyor that 2006 aerial survey basis of design meets state survey requirements. (FSP) Partially addressed. Applicant response: `As discussed in the meeting on March 5', Roudabush and Gale have performed additional onsite survey and topography on the site, and have confirmed that the topography is accurate. This additional topo information has been added to the plan sheet and the note on the cover sheet has been updated to reflect this additional information.' Asfollow-uj2: Revise (1A) Topo and Survey Note as requested in lead paragraph, p. 1. Please state that `topographic survey performed in support of design meets state code requirements for surveys.'

Inverts have been added to the yard drain system. Per the recent engineering's determination of roof drains, profile designs are not required for roof drains 8" in size or smaller.' As follow-up: Provide recent engineering determination, else do not rely on this response to request for design information for roof drains or yard inlet /pipe systems. Reviewer is unaware of this determination. If discussed March 5'", please share recollection. Engineering encountered yard /pipe installation issues on a recent project that may require developer to replace sections of pipe (prior to bond release). Reviewer is unaware of recent determination that would exempt a portion (in this case, critical portion) of drainage system from drainage review, or drainage design requirements. Notwithstanding recollections which may differ, Engineering does not request additional information /design revision in context of this review comment, for this project. Engineering Review Comments Page 9 of 12 49. Provide sealed engineering certification from Mfr. that Nyloplast® system elements meet VDOT drainage design specifications (equivalent load, deflection, strength rating, etc.). Settling is a major concern with design that proposes fill approaching 30' with entire pipe runs well above undisturbed ground, placed completely in fill. (Rev) Comment requests professional engineer's certification that a proposed material substitute for a VDOT standard be submitted. If there is settling in significant fill sections and pipe systems deflect or fail, review may be faulted for not requesting material certification of equivalent strength, resilience, etc. of proposed substitute to a VDOT reference standard (FSP) Withdrawn. Applicant response: `As discussed in the March 5' meeting, the storm pipe and plastic Nyloplast design is in accordance with the specifications and requirements.' 50.

Provide grading that ensures runoff from slope between PIP and building 1 does not reach building 1, but is conveyed via swale to yard grate inlet/s on the N side of building 1. (FSP) Addressed. Applicant response: `The arrows north of Building # 1 are correct, there is positive drainage away from the building and positive drainage down the slope of the hill. These intersect to drain into the yard inlets, as shown.' 56. At wet pond, revise design to ensure pipe is aligned with riprap; otherwise, wet pond slope will erode. That is, direction of flow cannot change once it exits pipe. Ensure riprap and last pipe section align. Additional MH /pipe section may be required. Revise WPO201800027 to reflect change to site plan. Revise easement plat to reflect change to private drainage easement. 57.
