Re: SUB -2015 -00102 Dunlora V Prelin,ivary Plat
Dear Mu. Roy:
We have reviewed the preliiiiinary plat for Dunlora V dated 15 as submitted by Timmons
Group elect,v,tically and offer the following coututents:
1. ITE Comae 230 i3 rur CundvminiumlTownnou3e. Based on the lot layout, it appears that
210 Single- family uetached would be more aPPropnat4.
2. The Traffic Generatiotl table should include a total Hu t for each street as this is used for
mini,nu,,, st,cet seUiuu requirements as aetined in Appendix B(1) of the Road Design
Mm-..al.
3. Per Table 1 in Appendix B(1 ) uf the Road DLs;gn Manual, the u,i„iu,un, width of the
proposed streets is /.4' face to face.
4. The Road Cross Section detail should clearly indicate that the street trees will be located
a minhauu, ut 37 bchi„a the back of curb.
5. 1 nc Road Cross Section should dearly indicate that the , ight -uf -way is to be a miuiu,um
of 1- beyond the edee Ur tFIC 3 ;dcwalks.
6. The Road Crass Section should clearly indicate whetn4, un- 3truct parking is prop03Ca ij-,
,tot.
7. Sight lines and profiles need to be provided at each iuuadway intersection.
S. The eA ;3t ; „g a3pnalt path along Shephe,a'3 Ridge Road appears to ba located outside of
the existinr Pedestrian easement. E ;tner additional cmc,,,c „t in the open space aria on lot
20 should be provided to cover the asphalt path, or the asphalt Patn snuuia uz; rm-mcated
within the existing pedestrian easement.
9. A„ access easement is p, vpusea for TMP 6217-313. Rather than creating an easement.
could to ;3 area oc cu„,uyed to TMP 62F -313'!
10. Each fittin, in the waterline eraats tn,, potential w lCaKagz.. It would be preferable tar
the waterline to be installed with radial deflection instead of angle ntti.,,3 it mcatzd
under the paved surtace.
11. It i3 our understanding that the adjacent parcel aft of Belvedere Blvd. will be constructed
with r.rivate allied anCi that per Albe ... arle County Cvge, an inter - parcel connection with
Dunlora V will net be allowed. As such, Road B w;ii nvt be considered a Stub out ana
the alternative Branch Type turnaround should be replaced with a cul -de -sac.
Furthermore, this cul -& -Sac will be u petnianent turnaround and will need to be located
within aea;cateu night -of -way.
i/-. It seems that a connecti —.n ur tric pedestriaan rZt dift3 within Du„lv,a V to Rio Roaa
should be made.
13. It appea,5 that there will be an unpaved island in the center of the cul -de -sac for Road A.
This Should bu clearly noted at the plan. If there is rtot an unpaved island, the minimum
radius of the cul- de -3m; ;3 45' as notes it, Appendix B(1) at the Road Design Manual.
This radius can be reduced to 30' wnLn specifically app.u,,ed by Albe,narm County i„
conStlhation with emergency services.
14. It there will be an unpaved island in the cul -de -sac. the minimum radius of the island is
30' as indicates it, Appendix B(1) at the Road Design Manual. Furthennure, the travel -
wu.Y mz..d th% island wAi r,ced to be des;gnea as a 1 -way travel -way ill accordance with
Table -i in appendix B( l) of the Rvaa DC3ign Manual, rasa u..- Street parking will not be
allowed within the cul -de -sac.
15. All aetlectivn angles of the stuurm sewer system should be a minimum of 9U =. it appears
that the minimum 5utiection is not ,,,et un the storm Sewei located on Road B.
16. Directiunai a,,vri3 showing tnc now in the sto,,,, sewet system shoula be added to the
plan. It is assumed that the under5.ouna detention adjacent tv iet 9 Will discharge to the
storm sewer system in Rio Road.
17. Is the a ,&;ati,ig 15" RCP at Rio Road adequate to accommodate the discharge from the
u..aurground detention basin as well as the developed runott that will by -pass the
detention?
18. Is the existing 18'- mCr under Sher,herd_a Riagu Road adequate tu azeummodate the
developed runoff that is by- passing detention?
19. The Seco„aary Street Acceptance Regulations (SSAR) requires a minimum of two
externai connections. It appears that a cotu,ection will not be available to Belvedere due
to the develo,.met,t ca tnz adjacent parcel and VDOT has inaicated that there will not be a
new connection to trio noad. Written documentation rrm the Duniera HOA needs to be
ptovidcd indicating that the HOA will net allow a connection across land cu�entiy
owned by the HOA adjacent to Dunlora Drive in order tar this SSAR requirement to be
waives.
