ST0301-CS090831J August Ms. Tricia Hatley, P.E. Freese and Nichols 1701 North Market Street Suite 500 LB 51 Dallas, Texas 75202 RE: Bethel Road II ST 03 -01 Second Submittal Review Comments Dear Ms. Hatley: Following a review of the above referenced construction plans, the following comments are offered for your consideration: GENERAL COMMENTS 1. The 'Carter Crowley Properties', 'Tract 1 Crescent Real Estate', and "Tract V Crescent Real Estate' need to be corrected to show current ownership by the city. Ownership of 501 Bethel needs to be corrected to show correct ownership. These items need to be corrected on all corresponding sheets. 2. There is concern about the sidewalk being located against the back of curb. Is the sidewalk supposed to be 8' as opposed to 10'— this issue has been discussed in previous meetings. 3. 'Bethel' is misspelled on the Traffic Signal Improvement plan sheet's title block. 4. Sufficient detail must be shown on the plans for the TAS review. The city does not have any standard pedestrian details that are A.D.A. compliant — these details need to be included in the plans. COVER SHEET 1. The project number is 'ST 03 -01'. 2. Do not include any standard city details in the plans. Details are required for construction that deviates from, or is not shown, in the city's standards. SHEET 2 L General Notes: #8 — change "all hand pours" to "all pavement hand pours ". 2. General Notes #16 — the city will have to approve the use of any detours. The Traffic Control Plan must be approved by the city prior to implementation 3. General Notes #18 — the city does not have any standard details for the A.D.A. regulations for curb ramps. 4. General Notes #23 —the truncated dome brick pavers used in the curb ramps will be the only pavers used on the project. 5. Note 6 — the contractor will be responsible for submitting a SWPPP as part of the TPDES Construction Permit submitted to the TCEQ. 6. Note 19 — All concrete used for construction of storm sewer manholes and inlets shall be 3500 PSI (5.5 sacks) at 28 days. 7. Notes 8, 9, and 11 — need to ensure that these are current company names and contact numbers. 8. There are several notes pertaining the to franchise utility companies; some state 72 hours prior to construction and others state 48 hours. Can all of these notes be combined into one note? SHEET 6 Show house and property line at 501 Bethel. The driveway probably needs to be shifted to the east. Show traffic pole locations. Index of Stations and Offsets — under the notes, add a description of what the offset is pointing to. SHEET 7 1. Show all existing buildings and property lines. 2. Need detail of sidewalk treatment at drives. Crosswalk on drives can not exceed 2% cross slope. On the cross section sheets it appears that some of the drives exceed the 2% cross slope. 3. Will any A.D.A. parking spaces be required in the downtown area? Need to show the angle, length and width of a typical parking space. Show the type of pavement markings that will be used to identify parking spaces. 4. Need to identify any 'No Parking Zones' that may exist. Are there any time sensitive parking areas (deliveries or pickups to businesses) that need to be identified? Are there any mass transit pickup or drop -off zones that need to be addressed? 5. Trees are being planted adjacent to the sidewalk — will the tree branches be tall enough to meet the vertical protected zone requirements? Trees, signage, etc., must meet both the A.D.A. vertical and horizontal requirements. SHEET 9 1. Accessible curb ramp — the new TxDOT standards (PED -02) show 4' as the minimum curb width. 2. The word `pedestal' is misspelled in several locations. PLAN - PROFILE SHEETS 11 -25 GENERAL COMMENTS 1. The sidewalk is labeled as 8' but scales as 10'. 2. Need to show the access ramps at the drives. 3. The relocation of mailboxes needs to be addressed. The mailboxes need to be identified in the plans. Mail delivery during construction will have to be coordinated with the post office. 4. Existing water and irrigation meters, sanitary sewer clean -outs and manholes must be located in areas where they are not obstructed by parking or proposed enhancements. Any of these facilities located in the sidewalk or paving areas must be pedestrian and vehicular traffic rated. The city does not have standard details for some of these devices so they must be city approved prior to construction. The relocation of these facilities will need to be addressed. 2 .. ,.1'_ �►�+C.. DRAFT 5. Fire hydrants need to be a minimum of 3' and a maximum of 6' behind the curb. Fire hydrants that do not meet these criteria will have to be approved by the fire marshal on a case -by -case basis. 6. Need to identify and address the removal and replacement of all types of fences. The city usually does not replace barbwire fences with barbwire fences. 7. What do the crosshatched areas indicate — there is not a legend. 8. There are several areas where the new sidewalk adjoins existing concrete paved areas — how will this be addressed. Need to show the limits of the concrete removal. Maximum slope requirements will need to be taken into consideration. 9. The sidewalk needs to be located behind the curb inlets and not considered part of the inlet. 10. Need to address how the existing landscaping and irrigation will be maintained and/or replaced. SHEET 12 Station 8 +50 Lt. — Show the location of the relocated fire hydrant. Depending on the condition of the fire hydrant, it may need to be replaced. Station 9 +48 Lt. — there is a brick wall on either side of the drive that will be impacted by the construction. How will this be addressed? SHEET 13 Can the paved area at the southeast corner of S. Coppell Road be reduced? The new inlets are located at the end of the new sidewalk along S. Coppell Road. If the sidewalk is ever extended, there will be a conflict. SHEET 15 1. Need to meander the sidewalk to miss the trees on the city park property. SHEET 16 1. Any way to shift the roadway to miss the 48 -inch elm tree on the Dragon property? SHEET 21 1. Move the median noses and leave opening in the crosswalk — the noses should extend ± 5' past the crosswalk. The crosswalks should be ± 10' in width. SHEET 23 1. Meander the sidewalk to save the 36 -inch oak as well as any other large trees. 2. The current parking on the Robertson property and business is off street. This layout eliminates all of the parking to this business. Correct the spelling of 'Robertson'. SHEET 26 1. Detail 3 is incorrectly labeled — it should be Bethel and Coppell Road (N.) Intersection. DRAFT STORM DRAIN PLAN & PROFILE SHEETS 37 -49 GE NERAL COMMENTS 1. The plan and profile stationing on many of lines does not agree. 2. Can some of the extraneous labeling in the profile view be removed? We do not need a sump elevation or rim elevation on the wye connections. 3. Show the existing water line in the profile view. Will the existing water line need to be adjusted in any locations to avoid a conflict with the proposed storm drain? 4. Show the beginning and end stations of the curves. 5. Need to note on the plans that the contractor must use manufactured wye connections. 6. There is not a plan - profile sheet for the laterals. SHEETS 37 & 38 1. Is the inlet located at Sta. 6 +29.08 on Line "A ", and the pipe from the inlet to Sta. 2 +50.71 on Line "A" required? SHEET 40 1. There is no profile of Line "13-2". SHEET 41 1. The wye connection at Sta. 4 +55.15 is not shown in the profile. SHEET 43 1. There is no profile of Line "C -3 ". SHEET 44 L The wye connections at Sta. 1 +82.23 and Sta. 1 +96.85 are not shown in the profile. SHEET 50 1. Note 1 — 'contractor is misspelled'. SHEETS 51 — 54 1. The fire hydrant at Sta. 3 +95 is in the sidewalk. 2. The water services need to be stationed and the size, type, and length of service shown. 3. Are blow -off valves required on the water line on either side of the box culvert? How will the pipe be installed under the box culvert? Any air release valves required? CROSS SECTION SHEETS 1. Some of the grades are shown as ratios and some are shown as percents — use one delineation for the grades. The Parks and Recreation Department had the following comments that can be discussed in our upcoming meeting: rd DRAFT There are maintenance issues with the new right -of -way maintain the turf and trees? Will the irrigation be installed with this project? It would be great is the trail on the north side of Bethel Hearthstone Lane. F 44 � plantings.
