4.15-2 - The project’s impact at the intersection Require as a condition City Council and Public Draft and incorporate Deny project approval of SR 20-49 Southbound Ramps and Brunswick of project approval Works Department condition as part of Road shall be mitigated by constructing a third project approval eastbound through lane on Brunswick Road from East Main Street to SR 20-49 and other related improvements. The improvements are conceptually indicated in Appendix K as identified in the RTMF. This improvement would improve the operation of the intersection to an acceptable LOS C during the PM peak hour.

This improvement would be triggered when the proposed project generates 486 or more PM peak hour trips, as identified in Table 4.15-12. A trip generation study, which includes all previous phases, shall be submitted with each Tentative Map for the project to determine if the project trip threshold would be exceeded by development on the lots within the map. If so, construction of the

improvements, or bonding, as authorized by the Subdivision Map Act, shall be a condition of approval of the applicable Final Map.

If the project sponsor is required to construct the improvement, the project sponsor shall be eligible for fee credits against the traffic impact fees for that improvement that are otherwise levied for the project and to the extent not utilized for fee credits, for reimbursement for that portion of the costs which exceed the project’s proportional fair share cost of the improvement. The determination of allowable credits and/or reimbursements will be made at the time of project approval, development agreement, or tentative subdivision map approval.

This mitigation would project approval improve the operation of the intersection to less than Approved Projects conditions. The intersection would, however, remain at LOS D. This improvement is not included in the GVTIF and the project sponsor would implement the improvement after receiving approval by the Public Works Director/City Engineer.

This improvement would be triggered when the proposed project generates 351 or more PM peak hour trips, as identified in Table 4.15-12. A trip generation study, which includes all previous phases, shall be submitted with each Tentative Map for the project to determine if the project trip threshold would be exceeded by development on the lots within the map. If so, construction of the improvements, or bonding, as authorized by the Subdivision Map Act, shall be a condition of

4.15-4 - The intersection improvement of Dorsey Require as a condition City Council and Public Draft and incorporate Deny project approval Drive and Sutton Way is described as a roundabout of project approval Works Department condition as part of and included in the GVTIF and indicated project approval conceptually in Appendix K. This improvement excludes the extension of Dorsey Drive to the east and the project shall construct the easterly leg as a project cost. With implementation of the roundabout, the intersection would operate at acceptable LOS A.

This improvement would be triggered when the Dorsey Drive Extension is constructed and prior to any proposed project generated trips, as identified in Table 4.15-12.

If the project sponsor is required to construct the improvement, the project sponsor shall be eligible for fee credits against the traffic impact fees for that improvement that are otherwise levied for the project and to the extent not utilized for fee credits, for reimbursement for that portion of the costs which exceed the project’s proportional fair share cost of the improvement.

is identified in the RTMF and conceptually indicated in Appendix K.

This improvement would be triggered when the proposed project generates 324 or more PM peak hour trips, as identified in Table 4.15-12. A trip generation study, which includes all previous phases, shall be submitted with each Tentative Map for the project to determine if the project trip threshold would be exceeded by development on the lots within the map. If so, construction of the improvements, or bonding, as authorized by the Subdivision Map Act, shall be a condition of approval of the applicable Final Map.

If the project sponsor is required to construct the improvement, the project sponsor shall be eligible for fee credits against the traffic impact fees for that improvement that are otherwise levied for the project and to the extent not utilized for fee credits, for reimbursement for that portion of the costs which exceed the project’s proportional fair share cost of the improvement. The determination of allowable credits and/or reimbursements will be made at the time of project approval, development agreement, or tentative subdivision map approval. 4.15-6 - Two alternative mitigations were identified Require as a condition City Council and Public Draft and incorporate Deny project approval for the intersection. The first alternative is the of project approval Works Department condition as part of realignment of Idaho-Maryland Road approximately project approval 200-300 feet northwards and constructing a roundabout at the intersection of Brunswick Road and Idaho-Maryland Road. Dorsey Drive would then continue between Sutton Way and Idaho-Maryland Road, and continue eastwards from Brunswick Road. The second alternative is the retention of the existing alignment and construction of a roundabout


INS

at the intersection with Brunswick Road.

Alternative 1: Realigning Idaho-Maryland Road (City Preferred Mitigation): The intersection of Idaho-Maryland Road and Brunswick Road shall be shifted northwards by 200-300 feet, where the intersection would be at the bottom of the sag curve on Idaho- Maryland Road as shown in Figure Z-12 in Appendix K The extension of Dorsey Drive through the project would be realigned to intercept with Idaho-Maryland Road just west of Brunswick Road. A roundabout shall be constructed at the intersection of Idaho-Maryland Road and Brunswick Road at this realigned location, as proposed by the project, some trips would be diverted because of this realignment, but the analysis indicates that the majority of mitigation measures at other intersections would suffice for this condition.

Operating conditions at non-impacted intersections would remain the same. Detail of the analysis for the realignment is included in Appendix K. This mitigation would improve the operation of the intersection to LOS A. The GVTIF has identified improvements at this intersection. Improvement costs over and above the GVTIF estimates shall be funded by the project.

The improvement at the Idaho-Maryland Road/Brunswick Road intersection would be triggered when the proposed project generates 135 or more PM peak hour, as identified in Table 4.15- 12. A trip generation study, which includes all previous phases, shall be submitted with each Tentative Map for the project to determine if the project trip threshold would be exceeded by

development on the lots within the map. If so, construction of the improvements, or bonding, as authorized by the Subdivision Map Act, shall be a condition of approval of the applicable Final Map.


In addition to the installation of a roundabout, additional speed reduction measures shall be implemented on the northbound approach to warn motorists of the intersection control ahead. These could include high visibility traffic signs, flashing beacons, changeable message signs, speed monitoring signs and other measures appropriate to reduce downhill speeds. These additional improvements are not identified in the GVTIF and the project sponsor shall implement the improvements. These improvements would be implemented at the same time the intersection improvement is implemented.

The shift in traffic would cause the Idaho-Maryland Road/Sutton Way intersection to operate at an unacceptable LOS F on the worst approach. As part of the Alternative 1 mitigation, the project sponsor shall improve geometry and install a signal


at the intersection of Sutton Way and Idaho- Maryland Road. The installation of this improvement would mitigate the project impact and improve the overall intersection LOS to A. The improvement would be triggered when the proposed project generates 1,331 or more PM peak hour trips. A trip generation study, which includes all previous phases, shall be submitted with each Tentative Map for the project to determine if the project trip threshold would be exceeded by development on the lots within the map. If so, construction of the improvements, or bonding, as authorized by the Subdivision Map Act, shall be a condition of approval of the applicable Final Map.


Alternative 2: Roundabout: A roundabout shall be constructed at the intersection of Idaho-Maryland Road and Brunswick Road. This intersection is located on the downhill slope. The installation of a roundabout has been shown to reduce the number and severity of accidents. This mitigation would improve the operation of the intersection to LOS A. The improvement is identified in the GVTIF.


IN ..... ...... This improvement would be triggered when the proposed project generates 135 or more PM peak hour trips, as identified in Table 415-12. A trip generation study, which includes all previous phases, shall be submitted with each Tentative Map for the project to determine if the project trip threshold would be exceeded by development on the lots within the map. If so, construction of the improvements, or bonding, as authorized by the Subdivision Map Act, shall be a condition of approval of the applicable Final Map.


In addition to the installation of a roundabout, additional speed reduction measures will have to be implemented on the northbound approach to warn motorists of the intersection control ahead. These could include high visibility traffic signs, flashing beacons, changeable message signs, speed monitoring signs and other measures appropriate to reduce downhill speeds. These additional improvements are not identified in the GVTIF and the project sponsor shall implement the improvements. These improvements would be implemented at the same time the intersection


improvement is implemented. 4.15-7 - The provision of the roundabout at the Require as a condition City Council and Public Draft and incorporate Deny project approval intersection of Brunswick Road and Idaho-Maryland of project approval Works Department condition as part of Road (realigned or at the existing location) would project approval redirect the majority of traffic from the intersection of Brunswick Road and Whispering Pines Lane back to the Idaho-Maryland Road, but some project traffic would remain at the intersection; however, the decrease in traffic would fully eliminate the potential project impact. The LOS would improve to A with this shift in traffic. The project sponsor would, however, still be required to pay towards the GVTIF for the safety improvements identified by the City at this intersection.

This payment of fees would be triggered with every building _permit _application _for _the _project. 4.15.8 - The sight distances at the following Require as a condition City Council and Public Draft and incorporate Deny project approval intersections shall be reviewed during the design of project approval Works Department condition as part of phase of the project and grades/sight distance project approval constraints removed or vehicle movements restricted. Plans submitted for grading or building permits shall include verification by a professional engineer that sight distance has been evaluated.

The intersection of Sutton Way/#19, Idaho- Maryland Road/#24 and Idaho-Maryland Road/#21 shall be constructed to allow Right-in-Right-out movements only. The potential close proximity of access #10 and #11 will be reviewed in conjunction with adjacent intersections. 4.15-9 - The signal timing at the intersection of Require as a condition City Council and Public Draft and incorporate Deny project approval Nevada City Highway and Brunswick Road shall be of project approval Works Department condition as part of improved to meet future traffic volume demand. project approval This mitigation would improve the operation of the intersection to LOS D. The project sponsor shall enter into an agreement with the City for implementation of this improvement. This will require a LOS analysis of the intersection at the time building permit applications are submitted by the project sponsor to review the operating conditions at the intersection. When conditions deteriorate to unacceptable levels of service (i.e., LOS E or worse), the improvement shall be implemented. 4.15-10 - An additional westbound through lane Require as a condition City Council and Public Draft and incorporate Deny project approval shall be added to the two intersections at the of project approval Works Department condition as part of intersections of Idaho-Maryland Road and SR 20- project approval 49 Northbound Ramps and the intersection of Idaho-Maryland Road and Railroad Avenue. The signals at the two intersections shall be coordinated. This mitigation would improve the operation of the intersections to LOS B and LOS A, respectively. The addition of a westbound through lane is not included in either the RTMF or the GVTIF and the project sponsor shall enter into an agreement with the City for implementation of this improvement.
