RE:Ethanol Plant Design Survey

Highway Ethanol, LLC

Vesta, Minnesota

Dear Brian:

Thank you for the opportunity to submit this proposal for design survey services for your ethanol plant project.  As you may be aware, Yaggy Colby Associates has been involved with almost all Fagen, Inc., ethanol plants in Minnesota and Iowa in some manner.  In many instances, Yaggy Colby Assoicates has performed the design survey and site civil design.  In addition, Yaggy Colby Associates has provided such civil services for large development projects for over thirty-five (35) years.

It is our understanding that Highwater Ethanol intends to construct an ethanol production facility on land shown on the attached map.  It is further understood that the total land parcels involved is not exactly known at this time.  Therefore, the proposal will account for this.

The scope of services for your project will be broken into two phases: design survey and land survey.  The design survey includes gathering detailed topographic surface and utility features to provide the basis of design for the project.  The land survey leads to the legal documents which described the boundaries of the property.  More specifically, the scope of work for the above is as follows:

1.Design Survey

·Detailed survey of land surface features including roads, railroad tracks, fences, culverts, vegetation and structures.

·Detailed survey of utilities as located by the locating services.

·Drafting of survey data.

·Electronic file package to be sent to Fagen for design.

2.Land Survey

·Property research.

·Determination of property boundaries.

·Setting property pins.

·Developing plat of survey.

All above work is performed with state of the art equipment including GPS.

Yaggy Colby Associates proposes the above scope of services on an hourly rate basis with estimated fees as follows:

1.Design survey of Parcel 1 and 2 - $10,100

2.Design survey of all 3 - $12,100

3.Land survey of all parcels - $6,500

The above fees are based on minimal difficulty finding section corners and access with an ATV.  Should conditions arise or a change in scope of work be requested by the owner, a fee proposal will be submitted for approval.  Additional work will no proceed without authorization.

The firm’s standard terms and conditions have been included as part of this proposal.  Authorization of this proposal is for approval of costs only.  Yaggy Colby Associates will only perform the work requested by Highwater Ethanol.  Please feel free to call with any questions.
