ACDSM, 7.F. Table, Private Street (6 -lot) Standards are the "same as VDOT standards." Also: please see 14-412.A.3. (b.) — VDOT standard apply. Proposed design is not deemed equivalent to or greater than the applicable standard in the Design Standard Manual. Proposed 37' CL radius is equivalent to certain entrance standards, is far less than the least minimum radius found in VDOT Road and Bridge Standards Vol. 2, TC -5.01, Sheet 802.24, Design Factors for a Design Speed of 20 MPH (127 -ft, 160 -ft, 179 -ft ... ). Also: VDOT Road Design Manual, Appendix B(1), Subdivision Street Design Guide (SSAR), Table 1, for Min design speed of 25 MPH for up to 2000 ADT, minimum CL radius —200' Design does not adequately protect public health, safety or welfare. Engineering could support 20 MPH 127 ft radius yadditional VDOT design factors for a design speed of 20 MPH were met, but this appears impossible with subdivision layout —only 70' f separate 37' R curves. VDOT R&B Std./Vol. 2, TC -5.01/802.24, requires Lr, super elevation runoff section, and Lt, tangent runout section. Design should provide minimum horizontal curve radius that satisfies: VDOT R&B/Road Design Manual, and Albemarle County subdivision ordinance and ACDSM. [14-412.A.3.(b) allows agent to approve VDOT standards for Mountainous Terrain. See GS -SSR / Table 1, below — R =100'] (Rev. 1) Addressed. 3 May 2016 Applicant response: "Petyward Lane has been redesigned in order to meet VDOT and Albemarle County standards for a Private Street; the road has been divided into a private street segment, which retains the name of Petyward Lane and a private alley that has been named Priory Terrace."

For mountainous terrain, maximum percent of grade may be 16% for ADT up to 400 and 14% for 401-4000 ACTT. 2. 26'allowed for streets< 400 vpd with concurrence of local officials. 3. 36' allowed for streets that are internal to the sub -division, with concurrence of local officials. 4. Pavement widths may be reduced if parking is not allowed. See page 12 of this Guide for roadway width exceptions criteria. 5. 100' minimum radius allowed in mountainous terrain 6. For curb and gutter streets with parking lanes, the clear zone is accommodated within the parking lane. However, VDOT has established a 3' minimum setback requirement behind the curb. 7. Based on 25 MPH Design Speed Overall Plan, sheet 2, shows design of Petyward Lane is similar to prior -approved designs in blocks 13, 11, and 14. Engineering supports VDOT standards, yet if Lots 21-30 have frontage on Rowcross (please confirm w/Planning), it appears that only that portion of Petyward from Fielding Run to midway through the 37'-R curve at Lot 20 is, in strict terms, a private street. We strongly discourage blending streets and alleys. I am unsure if the approach has been tried or approved at Old Trail or elsewhere, but proposed design is similar to streets in blocks 11 and 14. The 37'-R curve does not meet VDOT Standards, but Killdeer Lane (Creekside) may suggest a possible approach: a median that signals road END. A similar feature could be used to indicate transition, street to alley, but design must accommodate fire rescue needs. An alley has no horizontal curve geometric standards. No combination of calming, control, signs, etc. will revise Engineering belief that VDOT standards apply to Petyward at this point, but perhaps combination of median calming, pavement reflectors, signs, etc, could be used to indicate street end/transition to alley. Killdeer Lane, image bele (note 110' R), may provide ideas or basis of discussion with Planning/Engr. Also, i3hote, 124/1 -5 2. Sheets 4-5: Add note "Coordinate with VDOT on need to repair or replace pavement on Glen Valley and Upland Drives at Intersections with Fielding Run if ongoing grading/development have damaged asphalt surface.

We have placed a turn advisory sign (W1-1) and an advisory speed sign (WP 13-1P) at each end of curve C19. VDOT has not requested additional signage for this segment of road; therefore, we will not be adding the chevrons to the signage for this segment of the road." 16. Sheets 9, 10, 11: See WP0201600009/ESCP comments (to be issued soon). (Rev. 1) Acknowledged. 17. Sheets 9, 10, 11: provide walk/curb, guardrail break/gap for permanent vehicular SWM facility access. (Rev. 1) Addressed. "RGA will coordinate with Stantec for the location of the stormwater management facility access. The appropriate entrance will be added once the location is determined." Sheet 10 18. Revise water meter placement. 5-11. space (side-by-side meters) has proven unworkable design (Collins Engineering), block 23, Baywick Circle, where it is too late to resolve a situation that includes intense homeowner dissatisfaction w/driveway entrance design. Note CG -9B, Standard Entrance Gutter, sheet 13: this detail will not work with driveway entrances separated by 5'. Encourage visit/review block 23. Please provide separate, per -lot (individual) water laterals that avoid meter placement in narrow 5' width between driveways. Lots 1-6, 8-13. (Rev. 1) Addressed. Photos [Removed with Rev. 1 review comments]—Baywick Circle/does not match CG -9B (5/6/14 County photos) Sharp curb taper at sidewalk is major source of complaint (wheel strike, car drop) 19. Related to item #18, revise driveway entrance design to match CG -9B dimensions. (Rev. 1) Addressed. Design specifies "roll top curb for the private streets and private alleys. This precludes the use of CG -9B for the driveway entrances." 20. Recommend show houses on Lots 1-22, 30-32. (Rev. 1) Addressed. "The house /house footprint will be selected by the individual buyers after the plans have been approved and the lots recorded." 21. Provide sanitary lateral, Lot 32. (Rev. 1) Addressed. 22. Avoid sanitary line/guardrail conflict. (Rev. 1) Addressed. Guardrail has been removed from design. 23. Recommend adopt variable width private drainage easement design that reduces width on residential lot portions across Lots 10-12, similar to block 15 ROAD Plan field revision to private drainage easements. (Rev. 1) Addressed. Sheet 11 24. Avoid sanitary line/guardrail conflict. (Rev. 1) Addressed. Guardrail has been removed from design. 25. Please provide separate, per -lot (individual) water laterals that avoid meter placement in narrow 5' width between driveways: Lots 15-18, 31-34. (see #18, above) (Rev. 1) Addressed. 26. Sheet 13: Provide VDOT guardrail detail. [VDOT R&B Spec/Vol. 1 -GR-2, 2A; sheets 1 and 2; rev. date 7/11] (Rev. 1) Addressed. Guardrail has been removed from design. 27. Sheet 13: Recommend pavement design with Site Plan. Pavement design is required with ROAD Plan. (Rev. 1) Addressed. As follow-up, see New item #36, below. (Rev. 2) Addressed. 28. Recommend Site Plan reference Old Trail Stormwater Master Plan under review. (Rev. 1) Addressed. 29. Provide Site Plan Note specifying that SWM design/Final SWM Plan required for a block be reviewed and approved prior to Site Plan approval of a specific block. (Rev. 1) Addressed. As follow-up, please revise title sheet Note stating that `Site Plan approval is dependent upon the approval of the Old Trail Stormwater Master Plan and Stormwater Management plans for blocks 10, 16, 17-18' to include reference to block 30 and to Master Plan acceptance, April 2016. [Also: E-mail, J. Anderson to Applicant: April 12, 2016 6:34 AM] (Rev. 2) Addressed. Engineering Review Comments Page 4 of 4 30. Recommend Applicant submit SWM plans for all blocks as soon as possible; recommend reference to design concepts presented in Stormwater Master Plan Update for Old Trail (MP), dated 5 Feb 2016. (Rev. 1) Acknowledged. 31. Recommend Applicant work closely with Planning on variance required to ZMA200400024. Variance is necessary since Final detailed design plans will differ from Sheet 3, GDP, ZMA200400024. It is a certainty that SWM design required to support development of blocks 10, 16, 17, 18 requires Zoning Variance, though not, at this point, a rezoning. Engineering, Applicant, Stantec/RGA are likely nearing acceptance of MP. A prerequisite to Site Plan approval is Variance to ZMA200400024 GDP/Sheet 3. (Rev. 1) Addressed /Comment withdrawn. [E-mail, March 21, 2016 2:59 PM, J. Anderson to Dave Brockman; Bill Ledbetter; Glenn Muckley: "Late Friday, Dave Benish and I examined Old Trail Village Stormwater Master Plan (Fig. 9) which shows proposed locations and types of best management practices (SWM facilities) proposed at Old Trail. We compared this figure/ concept plan with Zoning Plan of Development Sheet 3, d. 8/26/05 (Attached). Dave Benish believes Variance to ZMA200400024 is not required if Albemarle County enters an Agreement with Old Trail centered on Fig. 9, a suite of 11 biofilters and 4 retention basins."] 32. Similar to #31, recommend Applicant coordinate with Parks and Recreation, as needed, to obtain legal Agreements that allow permanent SWM facilities on Parks and Recreation property. (Rev. 1) Addressed. 3 May response: "Acknowledged. RGA and applicant [will] coordinate with Parks and Recreation to obtain all necessary legal agreements concerning this plan." 33. Encourage Applicant to cross-reference ESC/ROAD plan comments (to be issued shortly). (Rev. 1) Acknowledged. 34. Note: March Mountain, RGA, and Stantec have shown commitment and patience in meetings and studies focused on compliance with ZMA200400024, 9VAC25-870-96, -97, -98, over a period of several years. Engineering appreciates this effort, recognizes Dave Brockman's attention to detail, RGA's response to comments and deliberate commitment to plan review relationship, Stantec's comprehensive design efforts. These combined provide level of assurance relative to ZMA, current requirements, and future needs. This commitment, if less than obvious, is no less true. We appreciate in particular William Ledbetter and Glenn Muckley whose sincerity, patience, and availability to Engineering are cause for optimism. Dave Brockman lends level of support vital to success. We are grateful to all three. New 35. Minor: Recommend revise Block 10 Plant List table title include block 30, if true (Sheet 18) (Rev. 2) Addressed. Not required. 36.

The increased wastewater is proposed by the ACSA to serve 104 residential units in Old Trail Blocks 10, 16, 17, 18 & 30. Construction of these homes is expected to begin in late summer of 2016 with full build -out by late summer of 2017. We have reviewed the average daily flow of the RWSA systems that would receive this flow as proposed, and reviewed the appropriate design factors specified under the Virginia SCAT Regulations (9VAC 25-790). On the basis of these reviews, under present average daily flow conditions, RWSA agrees to accept the additional wastewater flow as specified above. Please be advised that RWSA does not reserve capacity in its system for a specific project, and this letter should not be interpreted in any way as a reservation or allocation of flow or the granting of regulatory approval related to other agencies. Substantial changes in future average daily flow to the RWSA systems, changes in regulations, or other future factors could result in changes in RWSA's capability to accept additional flow. We strongly request that ACSA update RWSA on the status of this project on an annual basis, and further require that a new request for flow acceptance be made for all or any portion or phase of the above request for which sewer extension design has not been approved under a Certificate to Construct by the appropriate regulatory authority and is under construction within twenty-four months of the date of this letter. An updated review for flow acceptance shall be requested if the project's scope, time frame or connection point as initially specified changes. Please note that under no circumstances can a direct connection be made into RWSA's interceptor system without the written approval and physical inspection by the RWSA Engineering Department.

Commissioner June 6, 2016 Ms. Megan Yaniglos & Engineering Staff County of Albemarle Department of Community Development 401 McIntire Road Charlottesville, VA 22902 Re: SUB -2016-00021 and SDP -2016-006 - Old Trail Blocks 10, 16, 17 & 18 Dear Ms. Yaniglos and Engineering Staff: We have reviewed the Road Plan and Site Plan, submitted by Roudabush, Gale & Associates, Inc., dated January 25. 2016 with a revision date of May 20, 2016, and offer the following comments: 1. Previous comment: "When on -street parking is proposed on one side, clearly identify which side of the street the parking will be located, the locations of "No Parking" signs should also be included. " Please clarify Highgate Row; will there be on -street parking? 2. Previous comment: "Sight line triangles should include the available sight distance, offset from the edge of travel way and centerline offset. The sight distances lengths have been corrected, however, the sight lines should be ineasured to the center of the lane. For example: the sight lines for Beechen Lane should not be extended into fixture block 30. When the lines are accurately drawn they significantly impact lots 1-9. " This comment is largely unaddressed. The Albemarle County Design Standards Manual, which actually only refers to stopping sight distance, does not apply to intersections of public streets. In the case of a private street intersecting a public street, the appropriate intersection sight distance for a 25 mph design speed is 280% please show this on all public street intersections. As previously noted, this will significantly impact lots 1-9. Note that decision point A should be located 4 feet from the centerline of the minor roadway and 14.5 feet from the edge of pavement of the major roadway; please ensure that this is the case for all sight distance triangles (point A at Golf DrivelRowcross Street appears to be less than 14.5 feet from the edge of pavement). Decision point B should be located in the middle of the nearest travel lane of the major roadway, decision point C should be located 4 feet from the centerline or the left edge of pavement. The right sight distance lines for the intersections of Fielding Run/Upward and Fielding Run/Byward are not completely shown as they extend beyond what is shown on this plan, as is the Ieft sight distance line for Golf Drive/Fielding. Please ensure that all public street intersections have sight distance triangles in accordance with Appendix B(1), pages B(1)- 19 & -20, and please show all offset dimensions for the sight distance triangles. 3. Previous comment: "Site Plan Sheetsl5-18: The intersection sight distance lilies should be shown on these sheets. The proposed plantings should not lie within the sight distance triangle. " This intent of this comment was to provide intersection sight distance lines on the profiles. Please do this once the sight lines are drawn correctly on the plans, per previous comment. If there are trees and landscaping in the vicinity of the new sight lines, please include on the profiles. If additional information is needed concerning this project, please do not hesitate to contact me at (434) 422-9894.

(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.] Requirements: 1. [32.5.2] Update all notes on the plans to reference the recently approved ZMA2015-001. Setbacks, lot sizes, etc all have changed for these blocks since the initial approval. Revise to state the current requirements. Rev1: Comment addressed. 2. [32.5.2; Proffers/COD] Provide a table that contains all the information regarding all the proposed blocks, built and unbuilt/under review. This table is necessary to track all the requirements of the ZMA. Rev1: Comment addressed. 3. [32.5.2] Will any of the lots be proposed as affordable? A minimum of 15% of affordable units are required per the proffer. Identify which lots/units will be affordable. Rev1: The lots need to be identified on the plan. The notes that were provided do not meet the requirements of the proffer. As previously stated, staff recently revised the letter of revision policy to allow non-physical changes to site plans to not count toward that three maximum LOR's allowed. 1 2. Affordable Housing. The Owner shall provide affordable housing units equal to fifteen percent (15%) of the total residential mots constructed on the Property, in the form of for -sale units, far -rent mnits, "accessory units" (as defined in paragraph 2(C)(3) herein), and "carriage emits" (as defined in paragraph 2(C)(3) herein) and subject to the terns herein ("Affordable Units"). The Affordable Units shall be reasonably interspersed throughout the Property as provided in this paragraph 2, subject to the requirements of the Application Plan and the Code of Development. If the Owner elects at its option to provide for -sale single family detached Affordable Units, such routs shall be applied toward the 15% requirement. Each subdivision plat and site plan for land within the Property shall designate the lots or units, as applicable. that will, subject to the terms and conditions of this proffer. incorporate Affordable Units as described herein. and the aggregate munber of such lots or units designated for Affordable Units within each subdivision plat and site plan shall constitute a ninirnurn of fifteen percent (15%) of the lots in such subdivision plat or site plan. Notwithstanding the foregoing, however, the Owner may "carry- over" or "bank" credits for Affordable Units in the event an individual subdivision plat or site plan designates Affordable Units that in the aggregate exceed the fifteen percent (15%) nninimuuu for such subdivision plat or site plan, and such additional Affordable Units may be allocated toward the fifteen percent (15%) minitnurn on any future subdivision plat or site plan, provided however, that the rnaxirnuum number of Affordable Units that may be carried over or banked shall not exceed fifteen percent (15%) of the total uuuts on any subdivision plat or site plan. 4. [32.7.9] Indicate whether or not the pocket parks will count towards the required acreage for pocket parks per the Code. Provide a table that shows how many, which blocks, and acreage to date for the pocket parks. QQv1: Comment addressed. Additional Comments: 1. Single family detached units do not require site plan approval. Block 30 does not need to be shown on the site plan, and subdivision review has not been done for this block or other single family detached lots.

The increased wastewater is proposed by the ACSA to serve 91 residential units in Old Trail Blocks 10, 16, 17, & 18. Construction of these homes is expected to begin in summer of 2016 with full build-out by the summer of 2017. We have reviewed the average daily flow of the RWSA systems that would receive this flow as proposed, and reviewed the appropriate design factors specified under the Virginia SCAT Regulations (9VAC 25- 790). On the basis of these reviews, under present average daily flow conditions, RWSA agrees to accept the additional wastewater flow as specified above. Please be advised that RWSA does not reserve capacity in its system for a specific project, and this letter should not be interpreted in any way as a reservation or allocation of flow or the granting of regulatory approval related to other agencies. Substantial changes in future average daily flow to the RWSA systems, changes in regulations, or other future factors could result in changes in RWSA's capability to accept additional flow. We strongly request that ACSA update RWSA on the status of this project on an annual basis, and further require that a new request for flow acceptance be made for all or any portion or phase of the above request for which sewer extension design has not been approved under a Certificate to Construct by the appropriate regulatory authority and is under construction within twenty- four months of the date of this letter. An updated review for flow acceptance shall be requested if the project's scope, time frame or connection point as initially specified changes. Please note that under no circumstances can a direct connection be made into RWSA's interceptor system without the written approval and physical inspection by the RWSA Engineering Department.

ACDSM, 7.F. Table, Private Street (6 -lot) Standards are the "same as VDOT standards." Also: please see 14-412.A.3. (b.) — VDOT standard apply. Proposed design is not deemed equivalent to or greater than the applicable standard in the Design Standard Manual. Proposed 37' CL radius is equivalent to certain entrance standards, is far less than the least minimum radius found in VDOT Road and Bridge Standards Vol. 2, TC -5.01, Sheet 802.24, Design Factors for a Design Speed of 20 MPH (127 -ft, 160 -ft, 179 -ft ... ). Also: VDOT Road Design Manual, Appendix B(1), Subdivision Street Design Guide (SSAR), Table 1, for Min design speed of 25 MPH for up to 2000 ADT, minimum CL radius =200' Design does not adequately protect public health, safety or welfare. Engineering could support 20 MPH 127 ft radius yadditional VDOT design factors for a design speed of 20 MPH were met, but this appears impossible with subdivision layout —only 70' f separate 37' R curves. VDOT R&B Std./Vol. 2, TC -5.01/802.24, requires Lr, super elevation runoff section, and Lt, tangent runout section. Design should provide minimum horizontal curve radius that satisfies: VDOT R&B/Road Design Manual, and Albemarle County subdivision ordinance and ACDSM.

For mountainous terrain, maximum percent of grade may be 16% for ADT up to 400 and 14% for 401-4000 ACTT. 2. 26'allowed for streets< 400 vpd with concurrence of local officials. 3. 36' allowed for streets that are internal to the sub -division, with concurrence of local officials. 4. Pavement widths may be reduced if parking is not allowed. See page 12 of this Guide for roadway width exceptions criteria. 5. 100' minimum radius allowed in mountainous terrain 6. For curb and gutter streets with parking lanes, the clear zone is accommodated within the parking lane. However, VDOT has established a 3' minimum setback requirement behind the curb. 7. Based on 25 MPH Design Speed Overall Plan, sheet 2, shows design of Petyward Lane is similar to prior -approved designs in blocks 13, 11, and 14. Engineering supports VDOT standards, yet if Lots 21-30 have frontage on Rowcross (please confirm w/Planning), it appears that only that portion of Petyward from Fielding Run to midway through the 37'-R curve at Lot 20 is, in strict terms, a private street. We strongly discourage blending streets and alleys. I am unsure if the approach has been tried or approved at Old Trail or elsewhere, but proposed design is similar to streets in blocks 11 and 14. The 37'-R curve does not meet VDOT Standards, but Killdeer Lane (Creekside) may suggest a possible approach: a median that signals road END. A similar feature could be used to indicate transition, street to alley, but design must accommodate fire rescue needs. An alley has no horizontal curve geometric standards. No combination of calming, control, signs, etc. will revise Engineering belief that VDOT standards apply to Petyward at this point, but perhaps combination of median calming, pavement reflectors, signs, etc, could be used to indicate street end/transition to alley.

Variance is necessary since Final detailed design plans will differ from Sheet 3, GDP, ZMA200400024. It is a certainty that SWM design required to support development of blocks 10, 16, 17, 18 requires Zoning Variance, though not, at this point, a rezoning. Engineering, Applicant, Stantec/RGA are likely nearing acceptance of MP. A prerequisite to Site Plan approval is Variance to ZMA200400024 GDP/Sheet 3. (Rev. 1) Addressed /Comment withdrawn.

Engineering appreciates this effort, recognizes Dave Brockman's attention to detail, RGA's response to comments and deliberate commitment to plan review relationship, Stantec's comprehensive design efforts. These combined provide level of assurance relative to ZMA, current requirements, and future needs. This commitment, if less than obvious, is no less true. We appreciate in particular William Ledbetter and Glenn Muckley whose sincerity, patience, and availability to Engineering are cause for optimism. Dave Brockman lends level of support vital to success. We are grateful to all three. New 35. Minor: Recommend revise Block 10 Plant List table title include block 30, if true (Sheet 18). 36.

Virginia 22701 Charles A. Kilpatrick, P.E. Commissioner February 23, 2016 Ms. Megan Yaniglos County of Albemarle Department of Community Development 401 McIntire Road Charlottesville, VA 22902 Re: SUB -2016-00021 and SDP -2016-006 - Old Trail Blocks 10, 16,17 & 18 Dear Mr. Anderson and Ms. Yaniglos: We have reviewed the Road Plan and Site PIan, submitted by Roudabush, Gale & Associates, Inc., dated January 25. 2016, and we offer the following comments: 1. The design speed should be provided on the plan sheets and profiles. 2. When on -street parking is proposed on one side, clearly identify which side of the street the parking will be located, the locations of "No Parking" signs should also be included. 3. Sight line triangles should include the available sight distance, offset from the edge of travel way and centerline offset. The sight distances lengths have been corrected, however, the sight lines should be measured to the center of the lane. For example: the sight lines for Beechen Lane should not be extended into future block 30. When the lines are accurately drawn they significantly impact lots 1-9. 4. Storm sewer computations, HGL computations and Storm inlet computations should be provided. Also, there does not appear to be any horizontal or vertical constraints to the storm sewer system therefore we do not recommend the use of DI -2's. 5. A detail should be provided showing the roadway layout with ADT of each roadway. This will support the pavement design. 6. Roadway Typical Section: The sidewalk and buffer/planting strip cross -slope should be shown graphically. Street trees should also be shown graphically with a dimension to the back of curb as applicable. The roadway design speed should also be identified. 7. Pavement Marking/Signage Plan a. Pavement markings and signage should be shown on the plan view. b. All markings and appropriate signage shall be shown in accordance with the current version of the MUTCD an&or the Virginia Supplement to the MUTCD. c. Individual signs should have the MUTCD sign label reference included on the plan. 8. Roll-top curb should not transition into CG -6 within the entrance radii. The transition should happen within the private right-of-way prior to the CG -12's. 9. Road Plan Sheets 9-11: additional spot elevations should be provided around entrance radii to ensure positive drainage. 10. Road Plan Sheet 10: a. Golf Drive- Station 23+50- the crown of the road has been shifted. Is this the intent? b. The drainage easement shown for storm structures 92 and 94 should be designated as private. 11. Road Plan Sheet 11: Rowcross Street - Station 17+70 thru 20+50- the grading does not accurately depict the proposed typical section, it appears as if a ditch is behind the CG -6. 12. Guardrail beyond the limits of the right-of-way will not be maintained by VDOT. In addition, guardrail itself can be a hazard. We do not recommend using guardrail if it is not warranted. Also, we do not recommend installing guardrail over the sanitary sewer line. The minimum depth of a GR -2 system is 6'. The depth of the post vs. sanitary depth and future maintenance issues should be considered. 13. Road Plan Sheets 16-19: The design speeds should be identified on each sheet. Also a landing, having a minimum of 50' in length and maximum vertical grade of 2% should be provided at each intersection. For example: Upland Drive, station 19+37, does not appear to meets the minimum landing requirements. 14. Road Plan Sheet 17: Upland Drive a. Station 24+19.83 Centerline elevation conflicts with Rowcross profile. b. For 25 mph the minimum K value in a sag condition is 26. The profile shows a K value of 24.10. 15. Road Plan Sheet 18: Rowcross Street a. The centerline elevation at intersection station 17.1.70.10 does not match sheet 11. CIL elevation of 661.92 vs. 667.33. The profile appears to have been drawn at 667.33. b. The GR -2 detail should be updated to the latest revision of 8.14. 16. Road Plan Sheet 20: a. Storm profile 31-33 appears to be missing. b. There are multiple areas where the proposed grades are not tied into the storm structures. For example: storm sewer profile 121-129, structures 1 B, 5, 37, 109, 53, 59, 51 etc. 17. Road Plan Sheet 23: There are multiple areas where the proposed grades are not tied into MH's. For example: R and S I8. Site Plan Sheets 15-18: The intersection sight distance lines should be shown on these sheets. The proposed plantings should not Iie within the sight distance triangle.
