GENERAL NOTES:

1. FIELD SURVEY WAS PERFORMED BY PENNONI ASSOCIATES INC., IN JUNE 2025.

2. EXISTING TOPOGRAPHY AND PLANIMETRIC FEATURES SHOWN ON THIS PLAN ARE BASED ON AN ON-THE-GROUND FIELD SURVEY, DERIVED

FROM GPS OBSERVATIONS AND TRADITIONAL SURVEY METHODS.

3. PLAN IS TIED HORIZONTALLY TO THE PENNSYLVANIA STATE PLANE COORDINATE SYSTEM (NAD83) AND VERTICALLY TO THE NORTH AMERICAN

VERTICAL DATUM OF 1988 (NAVD88).

4. COORDINATE WITH THE MUNICIPALITY OF NORRISTOWN PUBLIC WORKS DEPARTMENT FOR TRAFFIC CONTROL ASSISTANCE.

5. CONTRACTOR TO VERIFY DEPTHS AND LOCATIONS OF ALL EXISTING UTILITIES PRIOR TO START OF CONSTRUCTION WORK.

6. CONTRACTOR SHALL FURNISH ALL MATERIALS, EQUIPMENT AND LABOR TO INSTALL AND MAINTAIN ALL EROSION AND SEDIMENT CONTROLS, AS

NEEDED, TO ENSURE NO SEDIMENT RUNOFF ENTERS INTO EXISTING STORM SEWER.

7. CONTRACTOR SHALL FURNISH ALL EQUIPMENT, LABOR AND MATERIALS FOR LINE STRIPING OF INTERSECTION.

UTILITY NOTES:

1. THE UNDERGROUND UTILITIES SHOWN ON THIS PLAN HAVE BEEN LOCATED FROM FIELD SURVEY INFORMATION AND EXISTING DRAWINGS (SUE ASCE STANDARD 38-02 QUALITY LEVEL C). THE SURVEYOR MAKES NO GUARANTEES THAT THE UNDERGROUND UTILITIES SHOWN COMPRISE ALL SUCH UTILITIES IN THE AREA, EITHER IN SERVICE OR ABANDONED. THE SURVEYOR FURTHER DOES NOT WARRANT THAT THE UNDERGROUND UTILITIES SHOWN ARE IN THE EXACT LOCATION INDICATED ALTHOUGH HE DOES CERTIFY THAT THEY ARE SHOWN AS ACCURATELY AS POSSIBLE FROM THE INFORMATION AVAILABLE. THE SURVEYOR HAS NOT PHYSICALLY LOCATED THE UNDERGROUND UTILITIES. A PA ONE CALL (PRELIMINARY DESIGN) HAS BEEN PLACED FOR THIS PROJECT - SERIAL #

2. IT IS THE RESPONSIBILITY OF THE CONTRACTOR TO DETERMINE THE LOCATIONS AND DEPTHS OF ALL EXISTING UNDERGROUND UTILITIES AND STRUCTURES BEFORE THE START OF WORK AND TO TAKE WHATEVER STEPS NECESSARY TO PROVIDE FOR THEIR PROTECTION. THE CONTRACTOR SHALL HAND DIG TO LOCATE ALL SHOWN UTILITIES. THE PROFESSIONAL HAS DILIGENTLY ATTEMPTED TO LOCATE AND INDICATE ALL EXISTING FACILITIES ON THESE PLANS; HOWEVER, THIS INFORMATION IS SHOWN FOR THE CONTRACTOR'S CONVENIENCE ONLY. THE PROFESSIONAL ASSUMES NO RESPONSIBILITY FOR THE LOCATIONS OF UTILITIES SHOWN OR NOT SHOWN. COMPLETENESS OR ACCURACY OF LOCATION AND DEPTH OF UNDERGROUND UTILITIES AND STRUCTURES IS NOT GUARANTEED. IF CONFLICTS ARE FOUND THE CONTRACTOR SHALL IMMEDIATELY NOTIFY THE OWNER AND DESIGN ENGINEER FOR INSTRUCTION BEFORE PROCEEDING WITH WORK.

TH

CURB NOTES:

1. PROVIDE MATERIALS AND CONSTRUCTION MEETING THE REQUIREMENTS OF

PUBLICATION 408, SECTIONS 350, 409, 630, 676, 694, AND 695.

2. PROVIDE EXPANSION JOINT MATERIAL 1/2" THICK WHERE CURB RAMP ADJOINS ANY

RIGID PAVEMENT, SIDEWALK OR STRUCTURE WITH THE TOP OF JOINT FILLER FLUSH

WITH ADJACENT CONCRETE SURFACE.

3. CONSTRUCT CURB RAMPS WITH A MINIMUM 4'-0" X 4'-0" CLEAR SPACE BEYOND THE

CURB FACE, WITHIN THE WIDTH OF THE CROSSWALK AND WHOLLY OUTSIDE THE

PARALLEL VEHICLE TRAVEL LANE. SEE SHEET 7 FOR CROSSWALK DETAILS.

4. SEAL JOINTS WITH AN APPROVED SEALING MATERIAL.

5. PROVIDE SLIP RESISTANT TEXTURE ON CURB RAMP BY COARSE BROOMING

TRANSVERSE TO THE SLOPE OF THE RAMP. EXTEND TEXTURE THE FULL WIDTH AND

LENGTH OF THE CURB RAMP INCLUDING SIDE FLARES.

6. MODIFY CONSTRUCTION DETAILS TO ADAPT DIMENSIONS TO EXISTING CURB

HEIGHTSWHERE THE CURB IS LESS THAN THE STANDARD 8" HEIGHT.

7. CURB RAMP AND SIDE FLARE LENGTHS ARE VARIABLE AND BASED ON CURB HEIGHT

AND THE SIDEWALK SLOPE.

8. TO AVOID CHASING GRADE INDEFINITELY WHEN TRAVERSING THE HEIGHT OF CURB,

RAMP LENGTH NOT TO EXCEED 15'-0". ADJUST RAMP SLOPE AS NEEDED TO

PROVIDE ACCESS TO THE MAXIMUM EXTENT FEASIBLE.

9. NON-WALK AREA IS AN OBSTRUCTED OR GRASS/NON-PAVED AREA ADJACENT TO

THE PEDESTRIAN ACCESS ROUTE THAT IS NOT USED BY THE PEDESTRIAN FOR

ACCESS.

10. THE DETAILS DEPICT PEDESTRIAN PUSHBUTTON POLES TO ILLUSTRATE THE

RECOMMENDED PLACEMENT OF PEDESTRIAN PUSHBUTTONS. FOR ALTERATION

PROJECTS, PROVIDE ACCESS TO EXISTING PEDESTRIAN PUSHBUTTONS TO THE

MAXIMUM EXTENT FEASIBLE. INSTALL PEDESTRIAN PUSHBUTTON STUB POLES,

WHERE APPLICABLE, SO AS NOT TO CREATE PEDESTRIAN OBSTRUCTIONS.

11. SEE TC-8803 FOR ADDITIONAL PEDESTRIAN PUSHBUTTON DETAILS NOT SHOWN.

12. ALIGN DETECTABLE WARNING SURFACE TRUNCATED DOMES ON A SQUARE GRID IN

THE PREDOMINANT DIRECTION OF THE RAMP AND PERPENDICULAR TO CURB. SEE

PENNDOT PUB 72 RC-67 FOR INSTALLATIONS ALONG CURVED SURFACES.

13. PROVIDE DETECTABLE WARNING SURFACES (DWS) 24" MINIMUM (IN THE DIRECTION

OF PEDESTRIAN TRAVEL) ACROSS FULL WIDTH OF RAMP AT THE GRADE BREAK

NEAR STREET EDGE. PROVIDE DWS THAT CONTRAST VISUALLY WITH ADJACENT

WALKWAY SURFACES, EITHER LIGHT-ON-DARK OR DARK-ON-LIGHT FOR THE FULL

WIDTH OF RAMP.

14. FOR NEW CONSTRUCTION, DO NOT EXCEED 2.00% CROSS SLOPE ON THE CURB

RAMP OR PEDESTRIAN ACCESS ROUTE.

15. FOR NEW CONSTRUCTION AND ALTERATIONS, CONSTRUCT CURB RAMP AND FLARE

SLOPES WITH THE FLATTEST SLOPE POSSIBLE. THE SLOPES INDICATED IN THE

DETAILS SHOW THE MAX SLOPE ALLOWABLE. SLOPES THAT EXCEED THOSE

INDICATED IN THE DETAILS, OR CONTRACT DOCUMENTS AS APPLICABLE, WILL NOT

BE ACCEPTED AND WILL BE RECONSTRUCTED.

16. CONSTRUCT SIDEWALKS AT A LONGITUDINAL SLOPE NOT TO EXCEED 5.00%. FOR

ROADWAY PROFILE SLOPES THAT EXCEED 5.00%, CONSTRUCT PARALLEL

SIDEWALKS ADJACENT TO ROADWAY AT A LONGITUDINAL SLOPE NOT TO EXCEED

ROADWAY PROFILE SLOPE.

17. THE CHANGE IN GRADE AT THE BOTTOM OF THE CURB RAMP AND ADJOINING ROAD

SURFACE IS NOT TO EXCEED AN ALGEBRAIC DIFFERENCE OF 13.33%. THE COUNTER

SLOPE OF THE GUTTER OR ROAD AT THE FOOT OF A CURB RAMP, TURNING SPACE

OR BLENDED TRANSITION IS NOT TO EXCEED 5.00%. SEE SHEET 8 FOR DETAILS.

18. THE CONSTRUCTION STANDARDS DEPICTED ARE MOST APPROPRIATE FOR NEW

CONSTRUCTION. ALL CONSTRUCTION MUST MEET THE STANDARDS CONTAINED

HEREIN UNLESS OTHERWISE NOTED OR DIRECTED.

19. ALL SLOPES ARE MEASURED WITH RESPECT TO A LEVEL PLANE. THEREFORE, THE

LENGTH OF RAMP IS NOT SOLELY DEPENDANT ON THE HEIGHT OF CURB. (FOR

EXAMPLE, A 6" CURB DOES NOT NECESSARILY MEAN A RAMP LENGTH OF 6'-0" FOR A

12:1 SLOPE.

20. SIDEWALK WIDTH MAY BE REDUCED TO 4'-0", WHEN PASSING AREAS 5'-0" X 5'-0" ARE

PROVIDED EVERY 200'.

21. THE TRAVEL LANE IS DEFINED BY THE OUTSIDE EDGE OF THE WHITE PAVEMENT

MARKING LINE. IF A WHITE PAVEMENT MARKING LINE DOES NOT EXIST, THE TRAVEL

LANE IS DEFINED BY THE CONTRACT DOCUMENTS.

22. CONSTRUCT DEPRESSED CURB FOR CURB RAMPS FLUSH TO ADJACENT ROADWAY.

GRADE EDGE OF ROAD ELEVATIONS AT THE FLOW LINE TO ENSURE POSITIVE

DRAINAGE AND PREVENT PONDING. FOR LEVEL TURNING SPACES BEHIND

DEPRESSED CURB, ADJUST SLOPES TO PROVIDE POSITIVE DRAINAGE. AT THE

JOINT BETWEEN DEPRESSED CURB AND ROADWAYS, REMOVE EXCESS JOINT

SEALER AND COVER THE SEALED AREA WITH A LIGHT APPLICATION OF DRY SAND.

23. CHEEK WALLS ARE PERMITTED WHEN ADJACENT TO NON-WALK AREAS OR

ELEVATION DIFFERENCES CANNOT BE ACCOMMODATED BY FLARES OR GRADING.

GRADE GRASS AREAS OR OTHER NON-WALK AREAS AT 3:1 OR FLATTER. DO NOT

INSTALL CHEEK WALLS THAT INTERSECT THE PEDESTRIAN PATH.

24. CONSTRUCT TOP OF PLAIN CEMENT CONCRETE DEPRESSED CURB TO BE FLUSH

WITH ADJACENT SURFACES (RAMPS, SIDEWALKS, FLARES).

25. FOR CURB RAMPS THAT LEAD TO A SINGLE CROSSWALK, THE RAMP (EXCLUDING

FLARES) TO BE FULLY INSIDE OF MARKED CROSSWALK LINES.

26. A 4'-0" MAXIMUM DIGITAL DISPLAY LEVEL WILL BE USED TO VERIFY THE SLOPES OF

CURB RAMPS AND SIDEWALKS.

27. INSTALL DUMMY JOINTS WHERE RAMPS, TURNING SPACES, FLARES, AND

SIDEWALKS ABUT.

28. CONSTRUCT DEPRESSED CURB SLOPE TO MATCH ROADWAY PROFILE AND HAVE A

FLUSH CONNECTION. TRANSITION CURB RAMP CROSS SLOPE TO MATCH ROADWAY

PROFILE AS GRADUALLY AS POSSIBLE. DO NOT EXCEED 3.00% PER 1'-0" CROSS

SLOPE RATE OF CHANGE WHEN TRANSITIONING TO ROADWAY PROFILE.

29. DO NOT SCORE OR MAKE GROOVES ON SLOPED SURFACES. LINES SHOWN ON

DETAILS ARE FOR ILLUSTRATION ONLY. SEE NOTE 5.
