Subject: Vail's Front Door: Site Wnrk and Buiiding A —Garage and Loading Dock
(HCI Joh No. 26006)
Spring 2006 Utility Work—SVVNIP and Construction Dewatering Amendmen#
The deep utility work and road gradir�g in Vail Road, Willow Road and Gorc Creek Drive ���as
ariginally intended to uccur after the mass excavation. The scope �f this work is clet'ined as
Phase 2 of' our SWMP plan. Due t� delays in ot>t�aining the building p�cmit for the �reater
prc�ject we felt is was advantageous to take advantage af the spring shoulder season ta install the
deep utilities within the Public Righc of'Way.
Scope nf Work
Reference the �ittached sketcll for the limits of the scope of work. The scupe of woc•k consists o�:
1. Sanitary sewer service to the Chalets in Vail road from the stomi sewer manhole in the
intersection of Vail Road and VVillow Ro��d. Sanitary sewe�• se�•vice to the garage and
loading dock through the I_odge at Vail parking lot.
2. Storm sewer service to the Chalets �n the West side of tl�e projzct in Vail r•oad frorn the
storm sewer manhole in the inte�;section of Vail Road and Willo�v Road. Storm sewer
service ta the garage and )oading dock through the Lodge ar VaiI parking lot.
3. New waterline from int�rsection of'Vail and Wiilow roads to the Chalets on the we�r side
of project.
4. Upgrade of existing water rnain from 6" to 12" from the intersection of Vail and Willow
for approximately l IOLF.
S. Installation of g�u line from intersection of VJillow and Vail Roads to Chalets.
6. Re-grading of Vail roacl ta prc�posed final grade.
�. Inst�►llation of new curb and gutier and asphalt paving.
I3lVIP's
l. Installation of silt lence on dou�n hill side of all disturbed areas.
2. Protection of all exisring storm sewer inlet5 prior to eonstruction.
3. Protection oi'all new storm s�wer i��lets as chey are installed.
Canstruction Dewatering
Prior ta construction of this phase af work we had intended to pump �ny gro�mdwater we
encountered in the utility excavation into pum� trucks and to haul off sitc for clis}�asal. However,
due tn the large quantity of groundc��ater that we encountered the plan has been modified.

We anticipate that most of the grUUnciwater will be encauntered in ihe interseccion of Vail and
Willou� Roads which is our deepest point o1'excavation for all of the utility work. A Wei1• trink
will be located in the Lodge at Vail parhing lot (see att�ched sketch}. The water ��ill be pumped
from the excae�atian into the weir tank. Frc�m the weir tank it will be pumped thrc�ugh a bag
filtration system. After leaving the bag filtration System the watet• will be discharged directly
into the �torrn sewer via the inlets in the Lodge at Vail parking lot.
