<br />Re: Proposal for Flood Control Improvements on Henson Creek
<br />
<br />Gentlemen:
<br />
<br />This letter is our proposal to provide engineering design services for
<br />a flood control improvement project on Henson Creek. Outlined below is a
<br />description of the construction project, a list of services we will provide,
<br />and our proposed cost and work schedule.
<br />
<br />Item 1 - Description of Construction Project - The proposed project: includes
<br />construction of a flood protection berm on the ~orth bank of Henson Creek,
<br />extending from the highway bridge approximately 900 feet west to the mouth of
<br />Henson Canyon. The project will require removal of existing brush and unsuitable
<br />materials at the site, placement of imported fill material and placement of some
<br />riprap.
<br />
<br />Item 2 - Engineering Services - The following
<br />provided:
<br />1.
<br />
<br />engineering services will be
<br />
<br />2.
<br />
<br />Field Cross-sections and Profiles - No additional field surveys will
<br />be done by WestWater Engineering. We will utilize the existing
<br />cross-sections from a flood study, plus a profile done by Larry
<br />Lang. No in-place soil testing will be done.
<br />We will prepare a plan and cross-sections showing the new berm
<br />construction and location of the berm.
<br />We will provide guideline specifications for removing brush and
<br />site preparation for placing the earthfill and riprap.
<br />Bidding and Award - It is our understanding that Hinsdale County
<br />will build the berm; therefore, there will be no bidding or award.
<br />Inspection - We will not: do any construction inspection or surveying.
<br />
<br />3.
<br />
<br />4.
<br />
<br />5.
<br />
<br />Item 3 - Costs and Schedules - Our estimated costs for providing the Plans and
<br />cross-sections plus the guideline specifications is $500. We anticipate that
<br />we can complete the work within two weeks of the Notice to Proceed.
<br />
<br />If a Corps of Engineer's Permit is required, there will be an extra cost of
<br />$100. Also, if we are requested to make an application for CWCB grant funds for
<br />the project, there would be an extra cost for that, with the amount depending on
<br />the complexity of the grant application.
