The feasibility report will include a review of the calculated assessment rate per the assessment policy, the determined appraisal rates, and special assessment rates applied to past projects in the City of Arden Hills. City staff will review anticipated special assessments with the city council at a work session prior to finalizing the feasibility report. The final feasibility report will be presented at a city council meeting. TASK 7: FINAL DESIGN Final design and construction plans will be completed in AutoCAD Civil 3D and developed in coordination with city staff. Major design components will include: • Removals/existing conditions plans, including locations of all existing utilities identified in the field survey or as mapped based on subsequent utility coordination • Typical sections • Standard details • Erosion control plan and stormwater pollution prevention plan (SWPPP), if necessary, including proposed restorations • Grading plans for five proposed sediment removal locations and design of a new stormwater BMP retention pond • Sanitary sewer and watermain plan sheets ◦Assumes up to 10 gate valve replacements or additions to existing watermain and up to five hydrant replacements or additions to existing watermain ◦Assumes up to 10 trenchless sanitary sewer spot repairs ◦Assumes no watermain modeling or further evaluation of the existing system is required, however, this scope of work can be added in the future, if determined necessary • Storm sewer plan sheets, including structure invert/ rim elevations with profile views for identified storm sewer improvement locations ◦Assumes up to five storm apron replacements, up to 10 storm structure replacements or additions, and up to five locations of riprap rehabilitation at storm outlets ◦Modeling and analysis for spread and sizing of storm sewer is not required ◦Plans will include implementation of pumping operation updates for Karth Lake per city direction (to take the lake bounce from a 934 to 936 elevation range to a 6-inch bounce level) »Our proposal assumes DNR and RCWD coordination and/or permitting has already been completed and will not be required; also assumes hydrology studies and modeling have already been completed, are accurate, and can be shared for use in design »Our proposal assumes the selected options will require a single plan sheet and associated specification for modifications to the existing pump or up to replacement of the pumps, but no modifications or additional structures/ site improvements; if structure or site improvements are necessitated based on the selected option, our team can provide those design services for an additional fee »We will develop a drainage report that documents the final design modifications to Karth Lake water levels and inundation duration • Street plan sheets, including roadway alignment and widths • Trail plan and profile sheets, including trail alignment, profile, and widths • Retaining wall plan and profile sheet and potential improvements to the access area surrounding it ◦Full structural design of the retaining wall will be required for submittal from the selected contractor • Intersection detail sheet for the ADA pedestrian ramp improvements area only • Cross sections at 50-foot intervals, driveways, and critical design locations for the trails only • Signing and striping plan ◦No changes are proposed—where impacted by improvements, notes to salvage/reinstall signposts along with their associated signage will be included and striping will be replaced in-kind ◦All street signs, including street name blades, are assumed to be replaced as part of the project; city staff will provide a field inventory of actual needs once completed • Traffic control plan sheets • Preparation of statement of estimated quantities, including street, trails, utilities, and miscellaneous construction items, all consistent with MnDOT item designation numbers and measurement/payment requirements will be incorporated • Preparation of the project manual and specifications ◦Standard front-end documents provided by the city and edited by Bolton & Menk for project specifics ◦Special provisions and technical specifications for project-specific items of work 12 2026 PMP STREET AND UTILITY IMPROVEMENTS | CITY OF ARDEN HILLSWorK Plan and Project aPProach EXHIBIT A
