About this file
This document is a comprehensive engineering design plan for the High-Level Trunkline Capacity Improvements project by the City of Ann Arbor, Michigan. The project involves approximately 1,500 feet of new sanitary sewer infrastructure, including water main and storm water improvements, and road resurfacing along Washington Street and First Street. The project spans multiple street segments from Washington Street to Miller Street, with detailed engineering plans covering removal, construction, sanitary sewer, storm sewer, water main, and instrumentation work. The project is identified by RFP No. 25-39 and File No. 2024-001, with design and engineering work prepared under the supervision of Christopher Jay Elenbaas, P.E. and Tracy Crane Anderson, P.E.
The engineering plans include extensive details for traffic management, including four distinct detour phases, bike detours, and pedestrian access routes. The project incorporates sophisticated monitoring systems, including inclinometer installations, settlement monitoring points, utility monitoring points, and observation wells. The design includes provisions for maintaining pedestrian and vehicular access during construction, with specific requirements for accessibility, surface treatments, and safety measures. The plan appears to be funded by the City of Ann Arbor's public services department and involves careful consideration of existing infrastructure, underground utilities, and minimal disruption to the surrounding urban environment.

GENERAL NOTES
WHEN CLOSING OR RELOCATING CROSSWALKS OR SIDEWALKS, THE CONTRACTOR SHALL
PROVIDE DETECTABLE TEMPORARY FACILITIES AND INCLUDE ACCESSIBILITY FEATURES
CONSISTENT WITH EXISTING PEDESTRIAN FACILITIES.
TEMPORARY TRAFFIC CONTROL DEVICES FOR PEDESTRIANS ARE SHOWN. OTHER DEVICES
MAY BE NECESSARY TO CONTROL VEHICULAR TRAFFIC. STAGE WORK, AS NECESSARY, TO
PROVIDE AN ALTERNATE PEDESTRIAN ROUTE (APR) AT ALL TIMES. FOR ROADWAYS WITH NO
AVAILABLE DETOURS, MAINTAIN ONE OPEN SIDEWALK AT ALL TIMES.
PROVIDE A SMOOTH, CONTINUOUS, HARD SURFACE THROUGH THE LENGTH OF THE APR.
COMPACTED GRAVEL, AGGREGATE, OR SLAG MATERIALS ARE NOT ALLOWED. PROVIDE A
FIRM, STABLE, AND SLIP RESISTANT TEMPORARY WALKWAY SURFACE TO COVER SHORT
SEGMENTS OF ROUGH, SOFT, OR UNEVEN GROUND.
THE PEDESTRIAN TRAFFIC SIGNALS CONTROLLING CLOSED CROSSWALKS SHALL BE COVERED
OR DEACTIVATED BY THE CITY OF ANN ARBOR. THE CONTRACTOR SHALL SCHEDULE AND
COORDINATE THIS WORK WITH THE ENGINEER A MINIMUM OF 72 HOURS (NOT INCLUDING
WEEKENDS & HOLIDAYS) PRIOR TO THE BEGINNING OF WORK THAT REQUIRES A SIDEWALK
CLOSURE.
POST MOUNTED SIGNS LOCATED ADJACENT TO A SIDEWALK SHALL HAVE A 7 FOOT MINIMUM
CLEARANCE FROM THE BOTTOM OF THE SIGN TO THE SIDEWALK SURFACE.
WHEN THE ENGINEER DETERMINES THAT THE CONTRACTOR'S OPERATIONS OR PLACEMENT
OF TRAFFIC CONTROL DEVICES HAS CAUSED A SITUATION THAT THE VISIBILITY OF A TRAFFIC
CONTROL DEVICE IS REDUCED ENOUGH TO CREATE A HAZARD, THE TRAFFIC CONTROL
DEVICES SHALL BE DELINEATED WITH FLAGS OR OTHER ENGINEER-APPROVED DEVICES AT NO
ADDITIONAL COST TO THE PROJECT.
MINIMIZE DISRUPTION TO PEDESTRIANS TO THE MAXIMUM EXTENT FEASIBLE BY PROVIDING
AN APR IN THE FOLLOWING ORDER OF PREFERENCE:
1. PROVIDE THE APR ON THE SAME SIDE OF THE STREET AS THE DISRUPTED ROUTE
UTILIZING BYPASSES.
2. WHERE IT IS NOT FEASIBLE TO PROVIDE A SAME SIDE APR, PROVIDE A DETOUR ON THE
OTHER SIDE OF THE STREET.
3. WHERE IT IS NOT FEASIBLE TO PROVIDE AN APR ON THE OTHER SIDE OF THE
ROADWAY, PROVIDE AN APR DETOUR WITH TRAILBLAZING SIGNS AS SHOWN ON THE
PROJECT PLANS.

SPECIFIC NOTES
CURB RAMPS SHALL BE 48" MIN. WIDTH WITH A FIRM, STABLE AND SLIP RESISTANT SURFACE.
PROTECTIVE EDGING WITH A 2.5" MIN. HEIGHT ABOVE THE RAMP SHALL BE PLACED WHEN A
CURB RAMP OR LANDING PLATFORM HAS A VERTICAL DROP OF 6" OR GREATER OR HAS A SIDE
APRON SLOPE STEEPER THAN 1:3. PROTECTIVE EDGING SHOULD BE CONSIDERED WHEN CURB
RAMPS OR LANDING PLATFORMS HAVE A VERTICAL DROP OF 3" OR MORE.
DETECTABLE EDGING ANYTIME A HANDRAIL IS REQUIRED, AND ANYTIME THE PATH CHANGES
DIRECTION. THIS INCLUDES A TURN ONTO THE RAMP FROM THE PATH. DETECTABLE EDGING
MUST BEGIN A MAXIMUM OF 2.5" ABOVE THE RAMP SURFACE, AND EXTEND AT LEAST 6"
ABOVE THE RAMP SURFACE. CONTRASTING COLOR SHALL BE PLACED ON ALL CURB RAMP
LANDINGS WHERE THE WALKWAY CHANGES DIRECTION (TURNS).
CURB RAMPS AND LANDINGS SHALL HAVE A 2% MAX. CROSS SLOPE.
CLEAR SPACE OF 48" x 48" MIN. SHALL BE PROVIDED ABOVE AND BELOW THE CURB RAMP.
THE CURB RAMP WALKWAY EDGE SHALL BE MARKED WITH A CONTRASTING COLOR, 2" TO 4"
WIDE MARKING. THE MARKING IS OPTIONAL WHERE COLOR CONTRASTING EDGING IS USED.
WATER FLOW IN THE GUTTER SYSTEM SHALL NOT BE IMPEDED.
LATERAL JOINTS OR GAPS BETWEEN SURFACES SHALL BE LESS THAN 1/2" WIDTH.
CHANGES BETWEEN SURFACE HEIGHTS SHALL NOT EXCEED 1/2". LATERAL EDGES SHOULD BE
VERTICAL UP TO 1/4" HIGH, AND BEVELED AT 1:2 BETWEEN 1/4" AND 1/2" HEIGHT.
