Attached is a Scope of Work for professional assistance discussed during ow tour of the site. Basically, we will prepare an inventory of existing wetlands, overlay the mining opera- tions map to determine acres of impact,develop mining operation alternatives to minimize wetland impacts and prepare construction documents for wetland mitigation work. Addi- tionally we will provide professional assistance in coordination with the various agencies that have expressed interest in this project. Upon receipt of your notification we will begin inventory work. It is important to note that inventory work should begin almost immediatly as it will be difficult to identify wetland species with snow on the ground. Thank you for considering Tupa Associates for this work. If you have any gl.estions re- garding this proposal or work tasks associated with this proposal,please feel free to call. Sincerely,ItTi " Michael J. Tupa Landscape Architect ACCEPTED: AN}�ie, rl/ o Chairman, Board of County Commissioners Weld County, Colorado DATE: October 26, 1988 881C25 TL PA ASSOCIATES,INC. PROPSOAL WETLAND IMPACT IDENTIFICATION AND MITIGATION WELD COUNTY HOKESTRA PIT#2-WELD COUNTY COLORADO WORK SUMMARY Due to gravel pit operations,wetlands are to be disturbed primarily along the St. Vrain Creek floodplain.Gravel pit plans currently developed were reviewed by the ACE and the EPA and found to be lacking an adequate inventory of wetland condi- tions and needing a more comprehensive wetland reclamation plan. A. 100 foot levee is also to be constructed to contain flood flows of the St Vrain. Additionally,prop- erty owners desire an end product with ample wildlife habitat and large water acreage. The following work scope addresses those needed additions to the submitted 404 permit and offers an alternative analysis procedure which will allow us to present to EPA various mining plans which minimize wetland impact and insun:successful wetalnd restoration. SCOPE OF WORK 1. Inventory Wetland Conditions This initial work task involves identification of wetland areas on the site. Identifi- cation is made from aerial photographs and varified on-site. Since the wetland conditions are relative to the topographic features on this site mapping should be relatively easy. Vegetation, soils and hydrology will be noted as part of the three levels of identification needed for determining wetland conditions. Areas will be quantified showing acres of specific wetland types. inventoried wetlands will be mapped on the provided 1"=60' topographic base. Site wetland conditions and mapping will be prepared in report form for inclusiDn with the ACE permit submittal. 2. Analyze Impact Mitigation Levels This work task involves studying the proposed gravel mine phasing plans to de- termine impacts to identified wetlands. Acres where wetlands will be disturbed will be identified and mitigation needs outlined. Opportunities for mitigation are- as will also be explored. 3. Develop Mine and Mitigation Alternatives This work task will develope alternatives which the County can eviluate for pos- sible development. It is our intent to maximize use of the gravel resource while minimizing the impact to wetlands. At this time there are three alternatives to consider.The are: A. Full Mine with Mitigation per Original Plan Involves full 17.5 acre extraction plan as submitted to MLRB with mitiga- tion of impacted wetlands nearby. B. Partial Mine to Protect Existing Wetland Involves protection of existing wetland as staked by EPA. Requires a reduc- tion in available gravel extraction since the wetlands would not be disturbed. C. Modified Full Mine with Full Mitigation Replacement in Place Involves full 17.5 acre extraction plan with modification to the mining plan MITIGATION PROPOSAL 117Oct88 68 1025 VIOZS TL PA ASSOCIATES,INC. to install the levee in such a location to protect future wetland replacement ar- eas. Existing gravel resources under existing wetlands would be extracted and the wetlands replaced in the same location as they exist. An additional alternative may surface once the site is inventoried aid we have a better understanding of the opportunities and constraintes of the site. A draft alternative analysis report will be submitted to the County :'or review and comment. Adjustments to the analysis will be made prior to on-site discussion with the appropriate agencies. 4)Final Report We will prepare a final report for Weld County use and for inclusion with the ACE and MLRB permit submittal. The Final Report will cover the wetland find- ings, an evaluation of alternatives and recommended alternative. Agency coordi- nation letters,comments and responses to those will also be within the report. 5)Agency Coordination Considering the value of the gravel resource below the wetlands we felt that ex- ploring other options might be of some benefit to Weld County. With this in mind we contacted Brad Miller at EPA to see where he stood about considering alternative development plans.He indicated that while he still wanis to protect ex- isting wetlands he is open to consider alternative mining plans.Hence, we feel it is appropriate to present development options as described above. We may have some presenting to do to sell anything other than their recommend- ed layout since EPA would rather not impact existing wetlands. We would have to convince them of: 1) value of gravel resource, 2)our ability to restore dis- turbed wetlands, and 3) short term impact to wetland for long term gain in river- side habitat We also understand that some coordination with the Division of Wildlife, ACE and the property owner will be necessary. 6) Construction Documents Adjustment of the alternatives design work will be needed to convert the mitiga- tion plans to construction documents which can be used by the contractor. We will prepare construction plans and specifications which will direct contractor work in the mitigation of wetland impacts. TIME FRAME Upon receipt of your written notification to proceed,we will begin in ventory work. It is important to note that once snow flys it will be difficult to identify wetland spe- cies and soil conditions. Ideally, if work begins this month we will have the invent- ory and alternative analysis work completed before Thanksgiving and you can get this project underway. At that time we should be able to submit the modification to your permit application and would expect some favorable reaction from the various agencies. MITIGATION PROPOSAL 17Oct88 881025 TUPA ASSOCIATES,INC. COST ESTIMATE We estimate the following work level for the above discussed work tasks. TASK COST 1) Inventory Wetland Conditions $ 2,000 2)Analyze Impact Mitigation Levels 1,600 3)Develop Alternatives 3,200 4) Final Report 1,600 5)Agency Coordination 1,600 TOTAL $ 10,000 6) Construction Documents 2,400 TOTAL $ 12,4.00 Associated materials including reproduction costs and other direct project costs will be billed at cost.Milage will be billed at$0.30 per mile. It is not expected that these direct project costs will exceed 10%of project costs.
