PROJECT DESCRIPTION

The proposed Colerain Road/ CR 90 typical section is two 12-foot lanes in each directionseparated by a 20-foot raised median. The purpose of this Revised Concept Report is to changethe urban shoulder section from 4-foot bike lanes and 5-foot sidewalks on both sides to a 10-footmulti-use path on the north side and a 5-foot sidewalk on the south side of proposed ColerainRoad as a cost savings measure while meeting Camden County's bike route system requirementsfor Colerain Road. The rural shoulder section from 2664 feet west of I-95 to relocated BrazellRoad is changed to an urban section to eliminate the need for barrier separation between thetravel lanes and the multi-use path on the proposed bridge over I-95. The rural shoulder section

PRELIMINARY FIELD PLAN REVIEW INSPECTION REPORT: P.I. NO. 0007414PAGE 2 CAMDEN COUNTY

from 3800 feet west of Winding Road is changed to an urban section. The substantial residential development planned for this area would use the sidewalks to the nearbycounty high school. The rural shoulder section for 440 west of Winding Road to 1500 feet east of Kings Bay Road would remain but implementation of Value Engineering Study alternatives changed the typical section from 4-foot bike lanes and 10-foot shoulders (6’6” paved and 3’6” grass) to 10-foot shoulders consisting of a 4-foot bake lane and 6-foot grass strip in each direction.

05-XXX TYPICAL SECTIONS

General Comments

GDOT has defined the Safety Edge as the standard treatment for the outside edge of all uncurbed pavements whether edge of travel lane or shoulder (excluding pavement behind guardrail). If it is not practical to provide the Safety Edge, then a decision to omit shall require a comprehensive study by an engineer and the prior approval of a Design Variance from the GDOT Chief Engineer. The Safety Edge placement should be noted on the construction plan typical sections, with reference to GDOT Construction Detail P-7 for details and method of quantity calculation. Verify that Safety Edge treatment is referenced throughout Typical Sections accordingly.

MAAI will verify that Safety Edge treatment is referenced throughout Typical Sections. MAAI will label both sides of applicable typical section and delete the label “Typ”.

The CONCRETE SIDE BARRIER shown in the plans are “slant face” TYPES 2-S, 2-SA, & 2-SB. Current GDOT drawings do not reference Std number. MAAI will label as GASTD 4948B.

The height range for the Visual Barrier should be listed.

MAAI will add the height range for the Visual Barrier.

The detour drainage structure quantities are specified as Lump but is not clear what lump sum item this is referring to.

The Detour Drainage Structure refers to each drainage structure (DI, MH ect.) and the linear feet of temporary pipe exiting said detour drainage structure as shown on the drawing series 20 temporary drainage profiles. MAAI will add note to the effect.

The MSE section of Wall No. 1 has a barrier not a coping. See Cross Section Drawing No. 23-055 and Retaining Wall Plans Drawing No. 32-001.

MAAI will verify the treatment on top of the MSE wall. The pay item and cross sections reference Coping B while the typical section on retaining wall drawing 32-001 shows a Traffic Barrier Type H per Georgia Stabilized Embankment Traffic Barrier and Coping Detail.

Drawing 06-002

Alternate Base Quantities: Typically GDOT uses the pre-mixed soil cement pay item. And required Portland cement is paid for separately.

MAAI will change pay items to 301-4141 SY Pre-mixed soil-cem Stab Base Crs, 6 in, incl matl and haul; 301-4161 SY Pre-mixed soil-cem Stab Base Crs, 8 in, incl matl and haul; and 301-5000 Tn Portland Cement.

On the staging cross sections it appears leveling is being shown around temporary pavement areas but no quantities are provided. For example see the section above the existing pavement at STA 96+50 on Drawing No. 19-241.

MAAI will verify leveling areas on construction staging plans and add quantities accordingly.

The typical Section for Colerain Road specifies leveling or variable depth milling but no item for variable depth milling is provided.

Drawing 06-003

Driveway quantities comments: The asphalt commercial driveway pavement layers is specified as 1.5” of 12.5 mm and 2” of 19.0 mm Superpave thus the 19.0 mm quantity should be higher than the 12.5 mm but there are location where it isn’t. For example see commercial driveway at STA 56+20 RT.

MAAI will verify the 12.5 and 19 mm superpave quantities shown for commercial driveways and revise accordingly.


Driveway quantities comments: General Note Drawing No. 04-001 specifies 8” Valley Gutter with 6” concrete driveway and 6” Valley Gutter with 4” concrete driveway. But on this drawing has 6” Valley Gutter with 6” concrete driveway specified. For example see driveway at STA 76+47 and STA 103+48 LT.

MAAI will revise the General Note Drawing No. 04-001 to specify 8” concrete driveway pavement with 8” Valley Gutter or 8” Valley Gutter with Curb and 6” concrete driveway pavement with 6” Valley Gutter to provide a uniform paving section and match summary of quantities.

Driveway quantities comments: General Note Drawing No. 04-001 specifies only 4” or 6” of concrete for driveways but on this drawing 8” is specified. For example see driveway at STA 12+50 LT.

Triple and double cross drain pipes are used in multiple locations throughout the project but on the summary they are quantified as a single pipe. For example see N2 RT at STA 113+79.6 where the linear foot is given as 192 feet instead of 192 x 3 = 576 feet. Also the rip-rap quantity is missing.

Triple and double cross drain pipes are used in multiple locations throughout the project. The drainage SOQ drawing and the pipe profiles list the structure number as Rt (right pipe), CTR (center pipe) and Lt (left pipe). Each structure number has its own pipe length shown. For example see N2 RT at STA 113+79.6 where the linear foot is given as 192, N1 CTR at STA 113+70.5 RT where the linear foot is given as 190, and N1 Lt at STA 113+63.6 where the linear foot is given as 191. The FFPR plans use a GaSTD 1125 HW for multiple lines as inlet and outlet structures. The skew of the cross drain accounts for the difference in pipe lengths.

Headwall quantities are not provided.

The FFPR plans use a GaSTD 1125 HW for multiple lines as inlet and outlet structures. The pay item Class A Concrete including reinforcing Steel is shown on the drainage SOQ drawings.

10-XXX TRAFFIC DIAGRAM SHEETS

The District 5 Traffic Operations recommends dual lefts onto Kings Bay Road.

MAAI will analyze HCS for dual lefts from Colerain Rd eastbound onto Kings Bay Road using the year 2019 Peak Hour Traffic of 335 as shown on Traffic Diagram drawing 10-004. It was discussed at the FFPR to look at converting the Colerain Rd inside eastbound thru lane to the second left turn lane versus adding another lane. This scenario will require HCS analysis of the thru and right turn lane movements with the year 2019 Peak Hour Traffic of 390 and 65 respectively. MAAI will submit results to GDOT for review, comment and or approval prior to revising plans.

11-XXX CONSTRUCTION LAYOUT/STAKE-OUT SHEET

The AASHTO Green Book recommends the use of horizontal curve lengths at or greater than about 15 times the design speed (expressed in mph). Curves 2, 5, 113, and 105 do not meet the AASHTO recommended minimum length for horizontal curves. The designer should ensure that


horizontal curves less than about 15 times the design speed have been selected based upon sound engineering analysis. A record of decision documenting the design judgment criteria used to justify the use of substandard curve lengths should be included in the project design records.

Based on the above comment all Colerain Rd horizontal curve lengths should be at least 45 MPH x 15 = 675 feet. Although Curve 2 has an arc length of 601.10 feet the radius is 32683.79 feet. This curve in conjunction with the reverse Curve 1 having a radius of 32071.76 is used to transition the two-lane existing to the proposed four lane divided Colerain Rd. To achieve the 675 foot arc would require even flatter radii which would extend the project limits.

Curve 5 has an arc length of 210.26 feet with a radius of 7000 feet. Being approximately concentric to the existing Colerain Rd. this alignment allows for constructing the proposed 20 foot median and two eastbound lanes right of and converting the existing two-way roadway to two westbound lanes. This scenario allows for simpler stage construction. To achieve the 675 foot arc would result in an alignment that requires additional required right of way and or more complex stage construction.

Although Curve 113 has an arc length of 410.58 feet the radius is 11459.16 feet. This curve compounds with a curve having an arc length of 2694.54 feet and a radius of 66000.00 feet. The large radii and total arc length of 3105.12 feet meet the AASHTO requirement for minimum curve length.

Although Curve 105 has an arc length of 460.33 feet the radius is 10000.00 feet. This alignment allows for transitioning the construction of the proposed 20 foot median and two westbound lanes left of and converting the existing two-way roadway to two eastbound lanes to the construction of the proposed 20 foot median and two eastbound lanes right of and converting the existing two-way roadway to two westbound lanes. To achieve the 675 foot arc would result in an alignment that requires additional length for the crossover. The longer crossover adversely impacts the staging by reducing the length of permanent pavement that can be constructed unless additional temporary pavement is used to maintain traffic.

Curves 2, 5, 113 and 105 have normal crown cross slopes, therefore superelevation is not a factor.

13-XXX MAINLINE ROADWAY PLAN SHEETS

Location of OBF needs revising as Req’d R/W is located behind it (27+80 to 33+00). R/W Markers is shown to be placed behind the OBF and work isn’t allowed behind it.

The OBF cannot be placed behind Required R/W or Easement because there are no rights to enter the property beyond said Required R/W or Easement. Therefore the OBF will be placed on the Required R/W or Easement line.

Ensure that Typical Sections, Mainline Plans and Cross Sections all match. For example, guardrail being installed at approximately 111+80RT to 114+80RT +/- isn’t shown in Typical Sections or Cross Sections.

The Rural Shoulder w/ Guardrail and Urban Shoulder w/ Guardrail Details on drawing 5-013 cover this and other applicable areas. A note “See plans for Location” is shown for each detail. The FFPR cross section drawings 23-034 show the proposed guardrail.

Clarify the need for the local service Rd. @ STA 29+00 RT. It appears to lead to a wetland.

Local Service Rd No. 2 was originally constructed under the Interchange Project to maintain access to the otherwise landlocked parcel adjacent to the I-95 southbound on-ramp. This project will relocate Local Service Rd No 2 beyond the Reqd L/A at the proposed right turn lane to I-95 southbound as shown to maintain access to the otherwise landlocked parcel adjacent to the I-95 southbound on-ramp.

Drawing 13-001

The super elevation rate for Curve # 41 and 42 for the relocated Service Road is not provided. Since the typical section specifies NC or RC and directs the Contractor to the cross sections similar instruction here would be useful.

MAAI will add super elevation rate and show SE transition info for Curve # 41 and 42 for the relocated Service Road.

According to the Cross Section Drawing No. 23-004 Service Road # 2 is outside of the existing topo and not tied in to the existing ground thus making impossible to quantify accurately the impact to Wet Land # 2 and ensure enough required right-of-way is acquired.

MAAI will complete existing groundlines Sta 30+50 to Sta 32+00 far right.

Bring water under driveway instead of bucking grade going under Relocated Local Service Road No. 2.

Although the Colerain Rd grade is going uphill the existing driveway at Sta 27+44 Rt is a high point because there is no existing sidedrain pipe to carry the roadside ditch under the driveway. The proposed ditch and sidedrain pipe shown on the FFPR plans retain the direction of existing ditch flow.

Verify that there isn’t a low point being induced in the SE quadrant of the intersection between Colerain Road and Relocated Local Service Road No. 2.

MAAI will verify that there isn’t a low point being induced in the SE quadrant of the intersection between Colerain Road and Relocated Local Service Road No. 2.

MAAI will add rip rap protection for cross drain under Relocated Local Service Road No. 2.

Clarify what type of spillway is placed underneath the 10’ multi-use path and 5’ concrete sidewalk. Flag with STD or Detail number. Ensure STD or Detail is provided.

MAAI will reference drawing number 38-001 showing the Special Catch Basin Detail.

R/W Markers are shown behind the OBF STA 28+62.98 RT to STA 15+12.09 (Relocated Service Road #2). No work is to occur outside the OBF. Move the OBF so that the markers can be placed. This applies to all locations where this occurs throughout the plans.


The OBF cannot be placed behind Required R/W or Easement because there are no rights to enter the property beyond said Required R/W or Easement. Therefore the OBF will be placed on the Required R/W or Easement line.

Drawing 13-002

WCR should be parallel to crosswalks, i.e. direct pedestrians into crosswalk. An additional WCR is needed in the SW quadrant for the EB travel crossing the I-95 SB On Ramp.

MAAI will verify all WCR are parallel to crosswalks. MAAI will add an additional WCR in the SW quadrant for the EB travel crossing the I-95 SB On Ramp.

The Office of Roadway Design suggests changing the Wheel Chair Ramp at about STA 35+00 RT to a modified B ramp to align better with the northeast and southwest quadrants. As shown it is oriented to the northeast quadrant only but the Signing and Marking Plan Drawing No. 26-003 shows it being connected by crosswalks to both quadrants mentioned. This comment also applies to Mainline Plan Drawing No. 13-003 refer to Signing and Marking Plan Drawing No. 26-004 at the ramps intersection.

MAAI will verify all WCR and crosswalk alignments. MAAI will verify the WCR type(s) in the southwest quadrant.

Verify the need for STRs C2.1 and D2 (Don’t appear to catch much water).

MAAI will verify the need for STR C2.1. Catch Basin D2 is used primarily to turn longitudinal storm drain to outfall D1 at proposed roadside ditch.

A R/W Marker is not shown at Const CL Sta PT 33+41.10 left because it is not a break but a point on Reqd R/W line between Sta 31+65.00, 105.00 to Sta 33+57.60, 115.00 Lt.

Drawing 13-003

WCR should be parallel to crosswalks, i.e. direct pedestrians into crosswalk. Determine if the WCR on the east side of the I-95 NB On Ramp can be shifted to better align with crosswalk.

MAAI will verify all WCR are parallel to crosswalks.

The Office of Roadway Design suggests if the drainage calculation will support it, that it would make sense to connect the side drain pipe from J4 to J2.2 instead of to J3.

Catch Basins Str J4 and J3 are located 38’ right of the construction centerline which is typically at the normal edge of the two lane pavement. This allows the proposed storm pipe from J4 to J3 to run under the right turn lane where there is adequate cover over the proposed 24” pipe.

The required structure depth of catch basin J2.2 to connect this 24” pipe would not allow for a positive pipe grade to structure 2.1 and outfall J1. It was discussed at the FFPR to connect J4 to J2.2 and possibly low point J2.1 then outfall to the proposed roadside ditch. MAAI will verify this scenario.

Explain or verify the need for both the 24” RCP from Drainage STR J-3 to J-4 and the 18” RCP from Drainage STR J2.2 to J2.1 to J2. Tie STR J4 to J2.2 and removing pipe from J4 to J3.


Catch Basins Str J4 and J3 are located 38’ right of the construction centerline which is typically at the normal edge of the two lane pavement. This allows the proposed storm pipe from J4 to J3 to run under the right turn lane where there is adequate cover over the proposed 24” pipe.

The required structure depth of catch basin J2.2 to connect this 24” pipe would not allow for a positive pipe grade to structure 2.1 and outfall J1. It was discussed at the FFPR to connect J4 to J2.2 and possibly low point J2.1 then outfall to the proposed roadside ditch. MAAI will verify this scenario which will delete 24” pipe J4 to J3, revise the pipe size J3 to J1 from 24” to 18” and delete 18” pipe from J2.1 and J2 MH.

It is not clear where the runoff from the driveway spillway at about STA 57+49 LT drains.

The proposed spillway replaces an existing drop inlet which outfalls into an existing roadside ditch in the northeast quadrant of Colerain Rd/ Brazell Rd (tie-in) which flows along the east (right) side of existing Brazell Rd (tie-in).

Explain the need for Drainage STRs H-1, G-2, J-1 and others like them.

Structures H1 and G2 as shown on pipe profiles 22-015 and 22-013 respectively are manholes used to drop inverts of 18’ pipes from the roadside catch basins to the outfall structures. This scenario allows for an outfall pipe grade of 1.00% thus a desirable outlet velocity.

Structure J2 is a manhole used to connect the 18” pipe from J2.1. This manhole would be deleted under the drainage scenario to connect J4 to J2.2 and possibly low point J2.1 then outfall to the proposed roadside ditch.

Place concrete spillways (GA STD 9013) at the end of curb and gutter along Ramps C & D.

MAAI will add concrete spillways (GA STD 9013) at the end of curb and gutter along Ramps C & D.

Add concrete spillways (GA STD 9013) at the end of curb and gutter along Christina Lane.

MAAI will add concrete spillways (GA STD 9013) at the end of curb and gutter along Christina Lane.

Verify that STR K24 is required. Drainage cross section shows pavement and curb and gutter sloping away from STR.

Structure K24 is primarily used to change pipe direction from left edge of roadway to the left (high) side of the median of the superelevated roadway. The catch basin will also intercept the two foot of left turn lane and two foot gutter. The drainage profile on drawing 22-025 is drawn to reflect the proposed longitudinal pipe out of the structure k24 and not the crosslope of the left turn lane pavement. MAAI will add the template from the construction centerline to structure K24 to clarify the interception of the runoff from the two foot of left turn lane and two foot gutter.

Add R/W Marker on PC 81+71.37.

A R/W Marker is not shown at Const CL Sta PC 81+71.37 right because it is not a break but a point on Reqd R/W line between Sta 81+24.00,62.00 to Sta 82+24.00 50.00 Rt.

MAAI will verify that STR Q6 is at a low point.

Utilize 4’ flat bottom ditches for outfalls for individual drainage structures.


The use of outfall pipes from individual drainage structures to the 4’ flat bottom ditch versus the longitudinal storm drain pipe shown would be a major design change that would affect the completion of the final construction plans and project let date.

In some areas the 4’ flat bottom ditch located at the toe of the roadway fill has a minimum grade of 0.002 ft/ft to convey the offsite water flowing towards Colerain Rd to the cross drains. The longitudinal storm drain provides a minimum 0.003 ft/ft grade to convey the roadway runoff to the cross drains. Combining the roadway and offsite runoff in the 4’ flat bottom ditch, if feasible, would require additional engineering time and costs.

A portion of the drive at STA 123+83 RT is off R/W and easement.

There is an existing 10’ utility and slope easement between the existing R/W and proposed driveway easement shown. This easement was a condition in the driveway permit approval that was reviewed by MAAI for compatibility with this project.

The District 5 Construction Office recommends replacing the existing 12” under Wildcat Drive with 18” RCP.

MAAI will replace the existing 12” under Wildcat Drive with an 18” pipe. The required P9 structure depth for an 18” pipe will require revising pipe inverts and structure heights for P8 to P2.

MAAI will add rip rap protection at outfall GG1.

Drainage STRs DD1, DD2, DD3, and the 30” RCP between them is off R/W. All permanent drainage STRs should be placed on R/W.

This existing drainage was originally on private property. The 7/19/2013 right of way plan revision added the existing right of way for Settler’s Hammock Way per plans obtained from the Camden County. The relocated drainage on Parcel 41B shown and labeled as Easement for Construction of Drainage (temporary) will need to be revised. MAAI will check the R/W acquisition status to see if the Parcel is closed and if we need to make the revision under another Parcel number.

Verify that the existing 30” under Settlers Hammock Way does not require replacement.

This existing drainage was originally on private property. The 7/19/2013 right of way plan revision added the existing right of way for Settler’s Hammock Way per plans obtained from the county. MAAI will consult with Camden County as to replacing the existing 30” under Settlers Hammock Way.

General Comments

Add a note that the moving of signals during staging is the Contractor’s responsibility with no additional cost to the department.

MAAI will add a project specific note to section 4 stating “Any adjustment of existing traffic signal(s) to maintain traffic as shown in the Construction Staging Plans shall be the Contractor’s responsibility at no additional cost to the department.”

Drawing 19-001

Proposed temporary ditches are shown on the staging cross sections but not shown on the staging plan drawings. For example see Drawing 19-001 and 19-037.

Proposed temporary ditches and pipes per cross section drawing 19-037 are shown and labeled on drawing 19-001 as “2’ FB Ditch” with flow arrows on drawing 19-001 & 19-002.

Stage 1


Water is trapped in median @ STA 70+50 (19-004 & 19-048).

MAAI will verify if water is trapped in median @ STA 70+50 (19-004 & 19-048) and add temporary drainage structures as necessary.

Determine if temporary barrier is really needed @ STA 156+50 to STA 159+00 (19-010 excavation for pipe is approx. 40’ from travel lane).

Temporary barrier is shown @ STA 156+50 to STA 159+00 to protect the traveling public from the adjacent construction and hauling equipment that will be required to remove 54” headwall, excavate and extend the 54” cross drain pipe.

Water in median travels from STA 236+00 to STA 219+00 before it can escape. Determine if a temporary pipe is needed, (19-015, 19-016, 19-091, and 19-096).

MAAI will verify if additional temporary drainage structure(s) and outfall(s) are required in the temporary 2’ FB ditch between STA 236+00 to STA 219+00 (19-015, 19-016, 19-091, and 19-096).

Explain the use of temporary asphalt @ STA 305+50 to STA 309+00 (19-022, 19-023, 19-122, and 19-123).

The variable width temporary pavement from STA 305+50 to STA 309+00 Lt (19-022, 19-023, 19-122, and 19-123) abuts the existing pavement. As shown in Stage 3 (19-213 & 214) this existing and temporary pavement is used to shift two-way traffic from existing Colerain Rd south of Kings Bay Rd onto the permanent pavement constructed in Stage 1 so that the remaining width of Colerain Rd can be constructed. Stage 5 (19-324 & 325) shifts two-way traffic onto pavement constructed in Stage 3 so that the remaining full width of Colerain Rd can be constructed. The use of variable width temporary pavement in the northeast quadrant of Colerain Rd/ Kings Bay Rd in Stage 1 eliminates the wedge construction of permanent pavement that would otherwise be required to remove the existing pavement in Stage 5.

Stage 3

There does not appear to be enough room for a left turn lane and barrier wall @ STA 36+00 to STA 38+40 and STA 47+50 to STA 49+43 (19-229, 19-194, 19-223, 19-195, 19-234).

The temporary barrier is located on the 2’ grass shoulder of Stage 2 construction (19-171 to 176). The barrier will remain in place until the left side of Colerain Road is brought up to grade. MAAI will show the Stage 2 left shoulder and slope line work on the corresponding Stage 3 cross-sections.

Water trapped in median @ STA 54+00 (19-195, 19-235, 19-236).

MAAI will reverse ditch direction so water flows to Sta 52+90 temporary DI 17T.

Settlers Way has a section @ STA 8+50 to STA 9+00 that is a single lane for 2 lanes of traffic (19-202).

The note “Lane closure on two lane road using flaggers shall be in accordance with the Manual on Uniform Traffic Control Devices for Streets and Highways …” is shown on the drawing.

Brazell Tie-In has a section @ STA 7+80 that is a single lane for 2 lanes of traffic (19-220, 19-221).



Jimmy Ln. has a section @ STA 13+00 to STA 14+00 that is a single lane for 2 lanes of traffic (19-196).


Stage 4

Jimmy Ln. has a section @ STA 13+00 to STA 14+00 that is a single lane for 2 lanes of traffic, (same condition in stage 3) (19-282).


Driveway @ STA 275+00 doesn’t have access (19-289).

MAAI will omit a length of median construction in Stage 3 to allow access to driveway Sta 275+00 Rt. The median will be constructed in Stage 5 as either an integral or curb & gutter median.

Ramp A @ STA 41+00 doesn’t appear to have enough room to get traffic to left side of ramp. Determine if temporary asphalt is needed (19-294).

MAAI will verify Ramp A @ STA 41+00 has sufficient width to get traffic to left side of ramp. MAAI will extend End Milling, Overlay and Widening Station/ Begin Full Width/Full Depth Pavement Sta 42+70 as required to provide sufficient width.

Stage 5

Driveway @ STA 141+25 has no access (19-312).

MAAI will omit a length of median construction in Stage 3 to allow access to driveway Sta 141+25 Rt. The median will be constructed in Stage 6 as either an integral or curb & gutter median. The integral raised driveway island will be constructed in Stage 6.

20-XXX CONSTRUCTION STAGING DETAILS

General Comments

The temporary pavement shown above the retained existing pavement appears to be constructed of leveling but on the Typical Section Drawing No. 05-14 for temporary pavement only full depth pavement sections are shown. Also the hatching used on the staging plan drawings depicts temporary full depth pavement. For example see cross sections from STA 164+50 to 165+50.

MAAI will add a temporary pavement typical section depicting areas of overlay & leveling. The temporary pavement legend does not differentiate between full depth or overlay and leveling. The hatching used on plans 19-010 & 011 reflect the overlay and leveling or full depth temporary pavement shown on cross sections 19-075 to 078. All faded back line work will be darkened for clarity.

The cross sections for the right section from STA 219+00 to 256+00 are not provided. Clarify what phase is going to be constructed.


Staging cross sections as well as plan sheets are currently included to verify traffic control and interim grading/drainage between areas under construction and existing pavement. Plan sheets are included to verify traffic control on newly constructed pavement and to show remaining roadway template under construction. Colerain Rd Sta 219+00 to Sta 256+00 Rt is shown in Stage 3, drawings 19-207 to 19-210, as constructing the remaining width of Colerain Rd. Adding cross sections for this latter stage which only completes the proposed roadway template would result in additional sheets to the plan set.

Drawing 19-091

Temporary concrete barrier are placed incorrectly. For example see STA 220+50 where it is shown as been buried by the construction fill and some barrier is shown being placed in the temporary ditch. This comment applies to other cross section showing similar situation.

Temporary concrete barrier shown at Sta 219+50, 220+00 and 220+50 is only required for construction of the cross drain. Once the pipe is placed, backfilled and the ground brought back to grade the temporary barrier can be removed. A note to this effect will be added to all applicable cross sections.

Some of the temporary ditch does not have outfall locations. For example see cross sections from STA 51+00 to 53+50. The low point for the temporary ditch is located at STA 53+00 but no outfall is provided. This comment applies to other ditches showing the same situation.

Assuming the comment applies to Stage 1 the staging plan 19-003 and temporary pipe profile 20-012 shows a temporary drop inlet 17T and temporary pipe to permanent drainage structures J3 to J2 and outfall J1.

Drawing 19-229

Proposed permanent pavement is shown being constructed under the temporary concrete barrier. For example see STA 37+50. This comment applies other cross sections with the same situation.

The temporary barrier is located on the 2’ grass shoulder of Stage 2 construction (19-171 to 176). The barrier will remain in place until the left side of Colerain Road is brought up to grade. MAAI will show the Stage 2 left shoulder and slope line work on the corresponding Stage 3 cross-sections.

Drawing 19-240

Explain if there is a reason why on some cross sections the travel lane is reduced to 10 feet even though it appears there is enough pavements to maintain 11 feet. For example see STA 93+00. This comment is applies to other cross sections with the same situation.

The staging crossover shown on drawing 19-006 has a baseline. The mainline cross sections show the offset from the construction centerline to this crossover baseline. From Sta 90+00 to Sta 100+50 there is a “one-foot” dimension to the left of this offset line which when added to the 10’ dimension shown equals an 11’ lane. From Sta 101+00 to Sta 102+50 there is a “varying” dimension to the left or right of this offset line which when added to the variable dimension shown equals an 11’ lane.

22-XXX DRAINAGE PROFILES

General Comments

The minimum required storm drain pipe size by GDOT is 18” but 15” is shown on the profiles. For example see side drain pipe from drainage STR D6 to D5.

The structure height of D6 for an 18” pipe does not allow for positive flow to outfall Str D1. MAAI will revise drainage layout to eliminate the 15” pipe.

Verify that catch basins are a minimum of 10’ from radius returns.

The centers of the catch basin boxes are a minimum of 5.17’ on the downstream end and 16.34’ on the upstream end from radius returns. These offsets satisfy the 3’and 6’ gutter transitions as shown on the Ga Stds.

Add hydraulic grade line for longitudinal systems.

MAAI will add hydraulic grade line for longitudinal systems.

For segments that exceed 45 degrees in delta, break the segments into separate lines.

Comment needs clarification for an MAAI response.

Add design year velocities at outfalls.

MAAI will add design year velocities at outfalls.

Label outfalls at the end of the pipe instead of the back of the STR.

The FFPR plans label the outfalls at the end of the FES or other precast structures and at the end of the pipe or box culvert for Headwall, Wingwalls and Parapets or other cast in place structures. Restationing all outfalls to the end of the pipe will require recalculating offsets and pipe grades accordingly.

Drawing 22-001

Add drainage profiles for STRs A1 through A7 and B1 through B5. Verify that there is enough depth between ditch elevation and EOP of roadway for proposed type of structure.

MAAI will add drainage profiles for STRs A1 through A7 and B1 through B5.


Drainage profiles for driveways are not required.

Drainage profiles for driveways are included in the plans to verify compatibility of ditch grades and pipe inverts, pipe lengths for quantities and pipe cover.

Increase the slope on pipes from 0.20% to 0.30% to match the slope of Colerain Road.

Ditch grades at the toe of fill are based on the existing ground and will not necessarily match the roadway grades.

Drawing 22-002

Longitudinal slopes are very shallow, should have a minimum slope of 0.22% for an 18 inch pipe to achieve a minimum velocity of 3 ft/sec when flowing full.

The longitudinal slopes for the 18” pipes from Str C5 to C2 are 0.21%.

Verify the need for a safety end section for STR D1.

MAAI will change outfall structure to 1120 FES.

Drawing 22-007

Propose Drainage STR D5 has a 15” and 18” pipe attached to it therefore the minimum height of the structure should accommodate the 18” pipe which is 4.17 feet for 1019B TP V-1. According to the information provided on the profile the height of the structure is ((25.71-22.28) +0.5) = 3.93’.

Per Ga STD 1019B Tp V-1 w/ hood the bottom slab thickness is 8”. Therefore 25.71-22.28 +0.67 = 4.10’ as shown.

Verify minimum depth of STRs D6 and D4.

Str D5 shows a structure height of 4.10’ versus the 4.17’ required per Ga STD 1019B. Str D6 shows a structure height of 4.76’ versus the 4.83’ required per the Ga STD 1033D. The difference of 0.07’ should not adversely affect the construction of the drainage structures.

Longitudinal slopes are very shallow, should have a minimum slope of 0.22% for an 18 inch pipe to achieve a minimum velocity of 3 ft/sec when flowing full.

The longitudinal slopes from Str D6 to D1 are 0.18%. The structure heights for an 18” pipe do not allow for a slope of 0.22%.


Verify the need for a safety end section for STR C1.
