Re: Wintergreen Farm — Redfields Sewer Pump Station
Dear Mr. Collins:
In response to our meeting yesterday with staff from the County of
Albemarle, this letter serves to document some of the history involved with the
Redfields Sewer Pump Station and the Albemarle County Service Authority's
(ACSA) desire to eliminate this pump station.
The Redfields Sewer Pump Station was constructed in 1995 by the
developer of Redfields to provide sanitary sewer service to 29 residents along
Kelsey Drive, and a portion of Wintergreen Lane within the Redfields Subdivision.
The pump station was necessary due to the contours of the area and the limited
amount of growth in this section of the development area.
In 2004, the ACSA participated in an oversizing of the Biscuit Run Sewer
Project that extended public sewer from the Mill Creek area to Mosby Mountain.
The ACSA financially contributed to the installation of a larger sewer main with
the intention of providing gravity sewer service to remaining portions of the
development area. This area included undeveloped portions of Redfields, Biscuit
Run, Oak Hill, Wintergreen Farm, as well as the elimination of the Redfields
Pump Station.
In 2010, the ACSA was involved in a Comprehensive Plan Amendment
(CPA201000001) for the development of Redfields Phase 5. During this review,
the ACSA indicated that gravity sewer service was required through the
Wintergreen Farm area. This gravity sewer would allow for the decommissioning
of the Redfields Sewer Pump Station.

During the ACSA's initial review process for Wintergreen Farm, the ACSA
requested that Riverbend Development explore the feasibility of connecting to an
existing sanitary sewer system within the Mosby Mountain Subdivision. This
connection would allow the ACSA to eliminate the Redfields Sewer Pump
Station, located directly upstream of the Mosby Mountain Subdivision. Due to
site constraints, the existing Redfields Pump Station does not have standby
power and is vulnerable in the event of a power outage or pump failure.
Included as attachments to this letter are several pertinent documents
related to this issue. I have provided a list of those attachments below:
• ACSA Memo dated July 15, 2003 concerning the oversizing of the Biscuit
Run Sewer Project.
• ACSA Comments to County of Albemarle dated November 17, 2006
indicating that gravity sewer would be required to serve Redfields Phase
5.
• Letter received from Preston Miller, President of the Mosby Mountain
Community Association dated February 26, 2015.
• Letter from the ACSA to Preston Miller dated March 3, 2015.
Based on the information provided, it is clear that the intent of the ACSA
was to decommission the Redfields Sewer Pump Station when a gravity sewer
option became available. If you have any questions, please feel free to contact
me at (434) 977-4511, Ext. 114.

Dear Mr.O'Connell,
As a matter of introduction,I'm Preston Miller,the current president of the Mosby Mountain
Community Association(MMCA). Our community is located off of 5th Street Extended/Old
Lynchburg Road about 2 miles south of the I-64.
We were recently approached by Riverbend Development which is in the process of developing a new
sub-division to the east of Mosby Mountain on the former Wintergreen farm property. Riverbend
Development has told us that they have been requested by ACSA to survey a sewer route from the
proposed Wintergreen development to connect to a sewer in the Mosby Mountain community.
Based on discussions with the Wintergreen developers and our understanding of the request,the
proposed route will require clear-cutting a broad swath of trees in the Mosby Mountain designated
Conservation\park area as defined by the MMCA Covenants and Restrictions and outlined on our plat.
It is our understanding too,that the proposed route will convey a permanent Right-of-Way that is
further conveyable to a third party. Some of our homeowners have expressed concerns since the
Conservation area provides the only community amenity with its stream,bridges,and walking paths.
To clear-cut a path through this area will virtually eliminate this amenity.
We are asking that you confirm whether or not your department has directed a feasibility survey be
conducted of the MMCA property and if this is the case,we want to understand the reasoning behind
this survey and to inquire what other alternatives are being considered. Any insight you can give us
into this proposed survey is appreciated.
We eagerly await your reply.
u for your time and best regards,

Re: Proposed Wintergreen Farm Development
Dear Mr. Miller:
The Albemarle County Service Authority (ACSA) recently received your letter
dated February 26, 2015 related to the proposed Wintergreen development adjacent to
the Mosby Mountain Subdivision. During the ACSA's initial review process for
Wintergreen Farm, the ACSA requested that Riverbend Development explore the
feasibility of connecting to an existing sanitary sewer system within the Mosby Mountain
Subdivision. This connection would allow the ACSA to eliminate the Redfields Sewer
Pump Station, located directly upstream of the Mosby Mountain Subdivision. Due to
site constraints, the existing Redfields Pump Station does not have standby power and
is vulnerable in the event of a power outage or pump failure.
As you will recall, I met with you and Jim Peterson on October 17, 2014 to review
potential sewer alignments through the Mosby Mountain Open Space. During the site
visit, we reviewed three alternatives for a possible sewer extension and they are
summarized below:
1. Install the sanitary sewer main directly behind houses along Rhett Court. This
would likely involve easements from the Nguyen property and the Mosby
Mountain Community Association. This option would not allow the ACSA to
eliminate the Redfields Sewer Pump Station.
2. Install the sanitary sewer main along the western side of the stream beginning at
existing manhole MosbyMtn-6-1. This manhole is located directly behind the
ACSA's Mosby Mountain Water Pump Station and would allow the ACSA to
abandon the Redfields Pump Station in the future.
3. Install the sanitary sewer main along the eastern side of the stream beginning
near existing manhole MosbyMtn-8-2. The feasibility of this option in allowing the

www.serviceauthority.org
ACSA to abandon the Redfields Sewer Pump Station is still unclear due to the
lack of survey information.
During the site visit, you expressed concerned with Option 2 as it would be
constructed across a steep slope and would be more visually impactful to the forested
landscape in this area of the neighborhood. You indicated that Option 3 would be more
feasible and could potentially involve fewer trees being removed. Based on this
understanding,we requested that the developer of Wintergreen Farm survey this area
to identify the large trees and determine if a sewer route is feasible through this corridor.
We would greatly appreciate your cooperation in allowing the surveyors to
perform the necessary field efforts so an educated decision can be made as to the
feasibility of this sewer alignment. If you have any questions, please feel free to contact
me at(434) 977-4511 Ext. 114.

MEMORANDUM

TO: J.W.BRENT,EXECUTIVE DIRECTOR C...
FROM: PAUL A.SHOOP,DIRECTOR OF ENGINEERING
SUBJECT: BISCUIT RUN INTERCEPTOR OVERSIZING
DATE:JULY 15,2003
At their June 2003 meeting the Service Authority Board agreed to participate in oversizing
the Biscuit Run sewer. This project is an extension by Beights Development Corporation to
serve the Mosby Mountain development.
On Friday,July 11,2003 competitive bids were received for this project. The apparent low
bidder was Saunders Construction with an offer 30%below the second lowest bid. Based
on the unit prices,the Service Authority share will be approximately$151,000. Saunders unit
prices are significantly below our estimate and I recommend we authorize Beights
Development to proceed with the contract.
