Work Element 3 – Path Alignment/Grading & Roadway/Traffic/Parking Lot Design (Stolfus)
30% Design
At project initiation, a conceptual opinion of probable cost (OPC) will be developed based on the Option 2
conceptual layout to plan for construction funding. Quantities and costs will be high level for planning purposes.
Roadway and trail design criteria will be confirmed. Designs will be developed based upon applicable Town,
County, and AASHTO standards, specifications, and guidance as well as the current state-of-the-practice around
accessibility design within the public right-of-way. We will assume PROWAG guidance applies to designs for the
project.
Stolfus will complete a (30%) design of the Avon pedestrian mall between Lettuce Shed Ln and Lake St as
depicted by Option 2 attached. It is assumed that the existing mall will be removed and replaced with a new
pedestrian path alignment. A horizontal and vertical alignment for the pedestrian pathway will be developed. The
design will be coordinated with urban design and landscape treatments, including 3 plazas. The slope of the path
will meet ADA requirements and connect to other pathways that connect to the mall. A preliminary 3-D model will
be developed to understand the grading necessary to tie-in and achieve drainage patterns that can be managed
with existing water quality treatments. If this cannot be achieved, recommendations for drainage and water quality
design will be identified with RESPEC per Work Element 5.
Stolfus will design an ADA accessible crossing of Mikaela Way and the necessary improvements to close
vehicular access on Mikaela Way at the crossing, including updated on-street parking layouts and circulation
treatments. In addition, Stolfus will design an enhanced raised crosswalk with RRFB’s at the Lake Street
crossing. On-street parking updates on Lake Street will be designed. Curb ramp layouts at street crossings will be
laid out, but not detailed. Associated signing and striping for the crossings will be included. Modifications to the
library parking lot will be designed and a 3-D model will be developed to understand the grading necessary to tie-
in and achieve positive drainage.
Stolfus will provide design data to DHM to prepare a 30% roll plot for review as described Work Element 4 and
will review the 30% roll plot prior to submittal to the Town. 30% plans will not be prepared. Estimated quantities of
major items and a 30% OPC with contingencies for minor items will be provided.
Prior to submittal to the Town of Avon, Stolfus will perform a quality control (QC) review of deliverables for
completeness, accuracy, and appropriateness. The Stolfus Project Manager will be responsible for scheduling QC
reviews with senior technical staff.
Stolfus will provide written responses to comments from the 30% design that will be addressed during 100%
design.
100% Design
Based on 30% comments, the design of the path, roadway improvements, and library parking lot will be advanced
to a 100% level. Stolfus will prepare project documentation of 100% plan, project specifications, and opinion of
probable cost. 3D models will be advanced to provide spot elevation details for the design elements and
confirmation of any ROW impacts. Curb ramps will be vertically designed with curb ramp details. Traffic design
plans with signing and striping and RRFB details will be prepared. Construction phasing and traffic control are not
included in this scope of work. Traffic control quantities will be estimated for Lake Street and Mikaela Way
improvements and a high level construction schedule will be prepared.
Stolfus will provide overall utility coordination for the project. Stolfus will review utility locates with the updated
designs and evaluate proposed design with existing utilities to identify impacts. Utility plans will be prepared and
potential conflicts will be identified through a utility matrix. Stolfus will hold up to 2 Utility Coordination Meetings
with the Town and affected utility companies to review impacts and relocations (one virtual and one in-person
meeting). The in-person meeting will be scheduled such that only one day is required to meet with all utility
owners. Additional one-on-one contacts via phone and email will be provided to coordinate relocations with utility
companies. Stolfus will also prepare a utility specification that outlines the utility impacts and actions by the
