- RFQ WILL BE ISSUED ON OR ABOUT 29 JULY 2010 SYNOPSIS Background The National Park Service is responsible for avoiding, to the extent possible, impacts associated with floodplain modification. The scope of this project includes the monitoring and analysis of the Toklat River floodplain upstream of, through, and downstream of the areas used for annual gravel extraction, near the Toklat Road Camp, as required by the Gravel Acquisition Plan Analysis EA Statement of Findings (2003). Cross-sections that were first established for this purpose in the late 1980s and early 1990s will be re-established and resurveyed, using the same local benchmarks as the original surveys. Project Activities 1. 2010 Topographic SurveyThe vendor will conduct a topographic survey of the cross-sections used to monitor the Toklat gravel scrape area. These cross-sections extend laterally from a line extending from the East Toklat bridge downstream to the left bankrock outcrop just downstream of the Toklat Road Camp. Minimum spacing between the cross-sections will be 300 feet. Surveys will extend from the right bank to the left bank, and all significant breaks of slope that occur across the channel will be surveyed. Important features to be measured include all active channels, floodplains, and the first floodplain terrace on each bank. Cross-sections will have a minimum of 40 points and a maximum of 100 points for each cross-section. Surveys will be on the same locations and vertical datum as historic surveys. 2. 2011 Topographic surveyThe vendor will conduct a topographic survey of the cross-sections used to monitor the Toklat gravel scrape area. These cross-sections extend laterally from a line extending from the East Toklat bridge downstream to the left bankrock outcrop just downstream of the Toklat Road Camp. Minimum spacing between the cross-sections will be 300 feet. Surveys will extend from the right bank to the left bank, and all significant breaks of slope that occur across the channel will be surveyed. Important features to be measured include all active channels, floodplains, and the first floodplain terrace on each bank. Cross-sections will have a minimum of 40 points and a maximum of 100 points for each cross-section. Surveys will be on the same locations and vertical datum as historic surveys. 3. Technical Analysis of Historic and Current DataAn analysis of the effects of gravel mining will be completed using all available cross-section data, aerial photographs, and scrape documentation. Individual analysis of all three data sources should be followed by a comprehensive analysis of the effects of gravel mining and assessment of success in meeting the goals of the related environmental assessment and finding of no significant impact. The vendor will process any and all historic data from previous years of cross-section surveys. Historic data will be included in a spreadsheet, and graphed. Analysis of any trends and recommendations for future park actions will be made. Additionally, the results from Denali shall be put into context with the observed effects of other gravel extraction efforts through a literature review. Deliverable Products 1.Interim analysis: analysis of 2010 cross-section survey and comparison to historic survey. 2.Graphical cross-sections and all cross-section data in numerical form (EXCEL file) for all years of available and useable data. 3.AutoCAD map of the Toklat River project area, showing the approximate location of the surveyed cross-sections, permanent elevation benchmarks, and temporary benchmarks, and appropriate local features. 4.Technical analysis of data regarding the trend in river conditions and geomorphological changes, both long- and short-term, where apparent.5.Analysis of available aerial photographs. 6.Analysis of available gravel extraction data. 7.Discussion of the effects of gravel mining on the river, including an evaluation of park gravel scraping allotments as defined in the Gravel Acquisition Plan Environmental Assessment and related observations on the park's execution of gravel scrapes.8.Recommendations for future monitoring and analysis of the Toklat River near the Toklat Road Camp. To include evaluation of scrape limit, with recommended revised limit and justification. 9.Literature review on effects of in-stream gravel mining that are relevant to the situation at the Toklat River. A final report will be prepared by the vendor and will be delivered to the National Park Service no later than 45 days after the completion of the fieldwork. This document will include project photographs, surveyed cross-sections, as-surveyed cross-section graphs, AutoCAD map, and a narrative describing the methods used to survey the cross-sections, and a monitoring plan for future monitoring efforts (2 hardcopies, an electronic version and CD in Work and PDF), and a powerpoint presentation summarizing the results. Electronic versions in original file formats, and a comprehensive Adobe Acrobat file will be submitted on compact disk.
