We requested comments from TxDOT but have not received any to date. No application for a TxDOT permit was submitted to date. This item will be officially submitted to TxDOT when a permit application is received. 1. Please remove all references to yellow stripping on drawing . All traffic stripping to be white. 2. Concerning drainage, will drainage come off University drive onto this street? How is drainage accounted for on street? Is a storm drain to the creek needed? 3. TxDOT required a traffic study to justify a traffic signal at this intersection. The traffic study shows traffic counts that warrant a "major collector" roadway section to Gateway Phases 1-4 . The roadway section from University Drive to the first access point complies with the traffic study. 4. The study shows traffic counts that warrant a "minor collector" roadway section to service Gateway Phases 2 and 4 . A minor collector is 38-ft B-8. • An addendum to the original traffic study has been submitted. The addendum reduces the traffic flow to 1254 vpd . According to City Subdivision Regulations, this still warrants a minor collector. The study states the 29-ft section with parking removed will handle the traffic . • However, it is our understanding that additional driveways are planned to access this roadway from Gateway Phases 1 and 3 north of this drawing . • The roadway should be constructed as proposed to the first driveway intersection shown on this plan . Call this intersection #10 . • The roadway should transition to a 38-ft section from the first driveway intersection to the second driveway intersection. Call this intersection # 11 . • The roadway can then transition from a 38-ft section to a residential section from that point into Phases 2 and 4 to intersection # 12. • If no intersections are planned from intersection # 10 to intersection # 12 , the roadway can be constructed as a residential section. 5. Sidewalks are required along all streets except cul-de-sacs. It is my understanding that this can be accomplished when site plans are submitted for adjacent tracts . 6. An additional valve is needed in the 12" water line northwest of the cross. Plan and profiles of the water line extensions are required for construction of this project. All utility lines under pavement to utilize ~tructural fill, as noted._ 7. Please indicate what is to be done with the water hne at the relocated fire hydrant. Tee removed? 8. Change Forest Lane to Forest Drive .

Brett McCully Assistant City Engineer Development Services City of College Station 1101 Texas Ave . Jeffrey T. Milburn, P.E. P .O. Box 10240 , College Station, Texas 77842 Phone 979-690-2560 Fax 979-690-2540 College Station, Texas 77842 Re: Gateway Driveway for Phases 2, 3 & 4 Dear Mr. McCully: Having recently been made aware of your concerns about the common driveway that is to be shared by the Gateway phases mentioned above I have been asked to respond to you directly by Stewart Kling of Kling Engineering. He forwarded me the email you sent to him on August 21 regarding the driveway width, traffic impact assessment and related issues. The TIA which I authored made an assessment of traffic expected to be generated by the overall Gateway development, including the areas that Mr. Kling is currently designing. At the time of the study (August 2002) the proposed development density was estimated at 340 units for the approximately 19 acres currently in the planning stages as Phases 2 and 4 of the Gateway project. The actual proposals for development show approximately 190 units. Consequently trip generation will decrease for this one area, called Area 14 on the trip generation tables, on a proportional basis . Trip generation previously estimated to be.2244 vehicles per day (vpd) should actually be more like 1254 vpd. Similarly afternoon peak hour generation should decrease from the previously estimated 238 vehicles per hour (vph) to a current estimate of 133 vph. While these changes are significant for the localized areas, they are not so significant to the overall project or for the signal warrant at Forest Drive. ADT at Driveway 8 in the study would decrease from 7669 vpd to 6679 vpd. Evening peak hour volumes would decrease from 720 to 615 vph. Following these volumetric changes into Table 9 of the TIA on page 31 thereof we find that the signal continues to be warranted despite the changes and no changes to the study recommendations are necessary due simply to the correction of estimated traffic volumes based on the actual development proposals currently before the City for review. Just for review, the minor street volume requirement for signal warrant is 200 vph.

As you are probably aware I have previously made a transition alignment drawing for this entry driveway at the point where the southern entrance to Gateway Phase 3 currently is under development. The remaining section of this letter will indicate my perspective on these issues. No recommendations about roadway width or geometric design of the interior circulation for Gateway were provided in the TIA of August 2002 . I have considered AASHTO design guidelines in making the following observations as opposed to City of College Station ordinance requirements . AASHTO uses a functional design concept as opposed to a volumetric design guide. This means that roadway widths, radii and so forth are selected based not on the traffic volume but on the functional class of the roadway itself Fundamental to the consideration of functional class are the expected service area of the roadway and trip length. For this entry drive the trip length is under 114 mile. This typically would be considered a local street, as opposed to a collector. The roadway will service two driveways to the commercial area, the north service drive and the driveway to the front of the retail portion of Phase 3, as . well as the residential area to the rear of the Gateway development. This could be considered a collector roadway in function, however the short trip length lends consideration more to a driveway/local street than anything else. There is no question that through movement is restricted on the subject roadway. Control of geometric features should be based on design speeds of 20-30 mph. This translates to minimum curve radii of 100-200 feet for adverse crown and reasonable lane widths. Greater radii are, of course, allowed. For short trip lengths, less than 1/4 mile, lower speeds consistent with this design assumption are expected. No tangent section between curves is necessary, however, the addition of brief tangent sections is sometimes helpful, particularly in longer length curves. Generally parking is allowed in residential areas and this expectation affects roadway width. In this development, according to Mr. Kling, fire lanes are expected to be established which will prevent parking adjacent to the curbs along the entry roadway and will allow the reduced roadway widths down to 28 feet (face of curb to face of curb). Two times of day are of particular interest for this development and this driveway/roadway Gateway Driveway Page 3 connection; these being the peak morning and evening hours . During the peak morning hour the adjacent commercial development will generate minimal traffic, mostly inbound and mostly to the Home Depot area directly. The geometrics of the primary entry drive and full width entry roadway to the south near Driveway 8 will provide excellent distribution of the traffic that enters the site there. Very little of that traffic will utilize the reduced section of this driveway/roadway. During the peak evening period there will be entering and exiting traffic to both the residential and commercial areas , however, the primary residential generation, frequently 70% will be inbound while the majority of the traffic using the north commercial entrance onto the reduced width roadway will head south . Very little southbound traffic from the residential area will access the commercial area of Gateway Phase 3 during this period. The reduced expectation of conflicts also argues for allowing reduced roadway widths . Recommendations 1. It is recommended that the reduced roadway width be allowed to the north of the initial connection of the entry drive at University and Forest Drive to the commercial Gateway Phase 3, based on the functional needs , expected speeds and reduced conflicts expected. 2. The reduced roadway width should not pose a reduction in function or safety for the residential or commercial areas within the Gateway development. 3. Fire lanes should be utilized to prevent parking and maintain function of the reduced width roadway . 4. Design criteria of the reduced width roadway may include centerline radii of 100-200 feet and little or no tangent sections between curves without significant deterioration of function. 5. The reduced width roadway may be reasonably considered a local street as opposed to a collector street based on trip length, function and area of service. 6. The traffic signal at Forest Drive and University Drive remains warranted by the projected traffic. If you have questions regarding this information or require additional information please let me know. Thank you for your attention to this matter. Sincerely tA~f!:!
