Exhibit A Statement of Work PROJECT NAME Rio Grande Reservoir Downstream Access Road GRANTEE San Luis Valley Irrigation District(District) INTRODUCTION The following STATEMENT OF WORK has been developed for the continuation of the Rio Grande Cooperative Project that includes a major component called the Rio Grande Dam and Reservoir Rehabilitation Project.The District plans to construct a new access road to the downstream toe of the dam as part of the Reservoir Rehabilitation Project.A new road will be built at a maximum of 10 percent grade and 20 feet wide. This will replace the existing narrow road with steep grades.The new road will allow delivery of materials (pipe,valves,and concrete)by truck for the ultimate rehabilitation project. BACKGROUND-Rio Grande Cooperative Project In 1927 the District completed a land exchange under the General Exchange Act of 1922 to acquire 146.81 acres of land from the United States located both above and below the dam for the Rio Grande Reservoir.The 1927 patent to the District did not include the lower face of the dam and lands along the Rio Grande River immediately below the dam,which remained in Federal ownership as part of the Rio Grande National Forest. Several components of the Project are located on these National Forest lands,including the northern face of the dam,extended outlet pipe,new outlet works,access road,lower spillway,and spillway plunge pool.The District recently completed the consolidation of land ownership by the District in order to complete dam facility repairs and improvements planned as part of the Cooperative Project. The dam safety and operational issues described above combined with the value of the reservoir for optimizing water use for multiple stakeholders in the basin have driven the District to move forward with the rehabilitation of the Rio Grande Dam and Reservoir.The District is a proponent of the Rio Grande Cooperative Project where the District works with multiple stakeholders,primarily the CWCB and the Colorado Division of Parks and Wildlife to restore the full use of the Reservoir. FUNDING AUTHORIZATION The CWCB's 2012 Projects Bill(125-002)authorized and appropriated a$5 million grant to the District to perform the design and other activities towards the rehabilitation of Rio Grande Reservoir,as part of the Rio Grande Cooperative Project. 12S-002 also authorized an additional$15 million towards to the project,as a loan/grant combination,which will be determined by the CWCB board at a later date.The CWCB has executed multiple projects with the District over the past few years. OBJECTIVES The objective of the project is to construct a gravel road.This will take this work off the critical path of overall Dam rehabilitation construction and perform the work at lower cost by utilizing an earthwork contractor. Having good site access during the pre-bid conference for contractors for the outlet work's rehabilitation project will produce more favorable bids.The access road is also a dam safety enhancement which allows large equipment to be mobilized quickly in the event of an emergency. PROJECT DESCRIPTION The Project involves the construction of a gravel access road to be built as shown on the design drawing included.The existing road will be lowered from station 7+40 to station 10+50 to get to the existing river level.The left bank of the river will be armored with very large riprap as shown on the plans with the access road built to about elevation 9380 feet.The Project is scheduled to be completed in the fall of 2017;however, 1
