Although some information developed for the former San Luis Marketplace project may still be relevant, many factors and circumstances have changed 6vor the decades of'time since passed. As we discussed at a February 27,`2014 meeting together with staff from. the San.Luis Obispo. Council of Governments and the Regional Transit Authority, the city should not regard,past ,decisions or any implied commitments related to US: l Q7 as forgo.nc ..conclusionsj iizolud ng but not limited to constructing a new interchange at Prado Road. Central to this discussion is access to US 101. For traveler safety and operational integrity of the freeway, a new interchange in an urban location such as this must be no closer than one mile to the next interchange. Because the Madonna Road and Los Osos Valley Road interchanges are less than two-miles apart now, this requirement cannot be met fora new Prado..Road interchange, Recognizing the city's stated desire to pursue new access as an option, however, it is critical for the city to establish a clear purpose and need for any new proposal, In support of that pursuit, we offer these suggestions: Milo ##$we AVrA k e y I i Conduct a thorough subarea traffic analysis of the circulation across, along and including the US 101 corridor between Los Osos Valley Road and Madonna Road. o Evaluate a full range of options to mitigate the lraf#ic:impacts of the new. development in A progressive sequence, to include: (1) making local circulation improvements. only, (2) establishing new local access only across US. 101, without conrteetipns, eliminating the existing northbound ramps, (3) modifying access at the two existing full access "Provide a safe, sustainable. lnlegraled and effloien! 1r6n,9pcir1pdon system to enhance Col(fornio's economy and livablllty" /4 COUNCIL MEETING: G r�o2 .Z��y ITEM NO.: iPhV Sri fo 1 A*eo b-1 G 0 cv k- iv Timothy Bochum, Deputy Director of Public Works RECEIVED June 16, 2014 Page 2 SEP 0 2 2014 interchanges, and (4) establishing a new connection with a full or partial aece s SLO CITY CLERK interchange at Prado Road. Should the analysis support new access at this location, the city should also anticipate the potential for numerous exceptions to design standards for a project on the State Highway system. While interchange spacing will be among the more.critical factors to address, a variety of other features and standards must be considered together and will. be equally important to ensure that a safe and effective product design will result. in addition, other features unique to the project site will require careful consideration: Floodplain - The drainage characteristics of the project location are well documented. The addition of impervious surface to the ranch property has significant implications for San Luis Creek and US 101, A revised flood plain map may be required by FEMA. Caltrans cannot approve any improvements or modifications to State Highway facilities until FEMA requirements are satisfied. In addition to coordinating with Caltrans' experts and FEMA, we suggest the city also coordinate with San Luis Obispo County and other agencies when approaching this subject, For more detailed information regarding hydrology and flooding with respect to the State .Highway please contact Mr, Ben Erchul of the District Hydraulics Department at (805) 549` -3391. Aviation safety and Airport Impacts - The San Luis :Ranch property is proximal to take -off and landing approachesfor all runways at the San Luis. Qbispo County Regional Airport. Locating new residential and commercial development within. and around these flight paths raises questions regarding airport operations and safety. We suggest that the city consult directly with the Caltrans Division of Aeronautics prior to issuing an RFP. Please contact Mr. Terry Barrie, Caltrans Division of Aeronautics, at (916) 654 -4151 to initiate a dialog on this topic. In conclusion, Caltrans values our partnership with the. city of San Luis Obispo, and we took forward to participating in the upcoming scoping meeting`regarding the development proposal. If you need to discuss these issues further with Caltrans please contact Mr. Larry Newland of my staff at (805) 549- 3103. Sincerely, Ai een K. Loe.
