This includes compiling information as follows: <br /> <br />1. Available Aerial Photographs <br />2. Ramsey County LiDAR Maps <br />3. National Wetlands Inventory Maps <br />4. Ramsey County Soil Survey Maps <br />5. MNDNR Public Waters Maps <br /> <br />Subtask 2.2a Level 2 Wetland Delineation <br />We will visit the site to delineate all aquatic resource boundaries within the designated study area. The <br />delineation will include performing transects and sampling in the vicinity of those wetlands, placing 3- <br />foot pin flags at the limits of any wetlands found. Our delineator will use a sub-meter GPS unit to <br />accurately locate and map each point and preparing a written report of our findings. <br /> <br />Subtask 2.2b Aquatic Resource Impact Permitting <br />Bolton & Menk will use the aquatic resource delineation to determine and prepare the appropriate permit <br />application to account for any aquatic resource impacts proposed by the project. This will include the <br />MN Joint Application to the U.S. Army Corps of Engineers and Local Government Unit, as well as an <br />MPARS application completed for review by the MNDNR. The applications will include GIS based <br />figures and sequencing analysis, permit narrative and project plan set. <br /> <br />Subtask 2.2c Meetings - Wetland Permitting <br />In some cases, the reviewing agencies request additional information and/or an on-site meeting during the <br />review process. If our attendance is requested at a meeting to discuss the acceptance of the delineated <br />boundaries or the agencies request additional information, this service will be provided on an hourly basis <br />at our Wetland Specialist rate. We have included one site meeting as a part of this proposal. <br /> <br />Task 2 Deliverables: A digital copy of the topographic survey base map, in AutoCAD, including <br />topographic survey, right-of-way and property line information. Aquatic resource delineation and <br />necessary wetland permit applications. <br /> <br />Task 3: Geotechnical Investigation <br />Bolton & Menk has retained Braun Intertec as a sub-consultant for geotechnical services for this project. <br />The purpose of Braun’s geotechnical evaluation will be to characterize subsurface geologic conditions at <br />selected exploration locations, evaluate their impact on the project, and provide geotechnical <br />recommendations for the design and construction of the trail improvements project. Braun’s proposal and <br />full scope of work is available upon request. The geotechnical evaluation will include: <br /> <br />x 6 Penetration Borings, ranging in depth from 10 to 14.5 feet <br />x 3 Penetration Borings, ranging in depth from 20 to 25 feet <br />x 1 penetration boring to a depth of 15 feet in the area of a stormwater pond <br />x Geotechnical Report including: <br />o Log of borings <br />o Summary of the subsurface conditions <br />o Discussion regarding reuse of on-site material during construction <br />o Recommendations for preparing structure and pavement subgrades
