The above improvements will alleviate most of the anticipated congestion in the City in 2030. However, improvements to CSAH 14, between CSAH 21 and I -35E that are being implemented today may not be sufficient to accommodate future traffic demand even with the improvements identified above. The solution to this potential congestion issue is not additional increases in roadway capacity, but system improvements described below that would occur in the post -2030 timeframe, and which would divert sufficient traffic away from existing CSAH 14 to eliminate potential future congestion issues. Enforcement of the land designated as Urban Reserve within the City's 2030 future land use plan is critical to ensuring the improvements to the transportation system before 2030 are sufficient. If land within the Urban Reserve is developed at a higher density than expected before 2030, the transportation system will suffer and additional congestion will be experienced. The next section discusses the full build -out system needs post - 2030 when the Urban Reserve portion of the City is developed. This illustrates the importance of the land use and transportation planning integration the City is striving for. Full Build -Out System Needs As the city looks toward the long -term future (i.e., beyond the 2030 planning horizon) and approaches full build -out of the community, it is assumed that the roadway improvements identified above will be implemented. To accommodate the additional development that is anticipated beyond 2030, further roadway system improvements will be required. Traffic forecasts for the City of Lino Lakes under full build -out conditions were prepared using the future households, population and employment data outlined in the socio- economic data section (Figure 6.6). A summary of the methodology used to develop these traffic forecasts is attached in Appendix C of the Comprehensive Plan. It is important to note that the full build -out forecast only incorporates 2030 household and employment projections for those areas outside the City of Lino Lakes. The most significant improvement that will be necessary in the post -2030 period will be the construction of a new roadway to connect I -35W and I -35E across the northern part of the City (Figure 6.7). What is referred to as the northern bypass would include new interchanges at both freeways and would create a continuous east -west route across the northern part of Lino Lakes. This improvement will be necessary to accommodate both regional traffic and additional local traffic that is expected with the full build -out of the City, particularly in the northeast. This roadway would be designated CSAH 14 and the existing CSAH 14 from I -35W through the regional park and Centerville would be re- designated. In addition to providing for regional and local traffic, this improvement will relieve congestion in the existing CSAH 14 segment between CSAH 21 and the east city limits and will reduce traffic as far south as CSAH 34. In addition to the northern bypass, additional county roads that would need to be upgraded to four -lane divided are as follows: • CSAH 32 (Ash Street) — from West Shadow Lake Drive to a new north /south roadway connecting Holly Drive East to CSAH 32 (Ash Street). • CSAH 21 (Centerville Road) — from CSAH 32 to CSAH 34. • CSAH 54 (20th Avenue) — from 77th Street to CR 140 (new CSAH 14) 6 -16 • • •
