6.0 PHASING AND SEQUENCING In general, capital projects that are expected to have significant roadway impacts should be constructed in conjunction with the undergrounding program to the greatest extent practical. However, a balance needs to be struck between maximizing projects within the undergrounding project schedule and overwhelming the community with construction impacts. Additionally, projects that are required due to public health, safety, and welfare needs should be implemented quickly and not necessarily delayed to coincide with a particular phase of undergrounding. Many of the Villages projects are non-bond funded projects, are relatively small in scope, and/or are located such that roadway impacts are minimal or have a brief schedule duration. Therefore, these projects are recommended to be constructed in accordance with their previously planned programming schedules. Some projects impacted by the undergrounding, such as landscape improvements, traffic calming, sidewalks, and street lighting should be delayed if possible to coincide with the undergrounding schedule. This will allow for additional restoration cost sharing benefits. There is also a recent stormwater master plan that identifies significant improvements but lacks funding at this time. Projects identified in this plan are to be funded by the Stormwater Enterprise Fund, however, that fund is inadequately funded. The Village recently engaged a financial consultant to develop new rates to begin to fund these projects over the long term. If financing permits, it would be extremely advantageous to perform these stormwater improvements during the undergrounding program, thus cost sharing restoration efforts. This would also decrease the impact to the residents in the long term. In our experience, most resident complaints come from people who live in areas impacted by undergrounding and capital projects at the same time. Provided the funding enables these improvements and the resident impact is managed properly, this master plan recommends that these infrastructure projects be constructed in conjunction with each undergrounding phase. Village of Key Biscayne Beach Renourishment Program The Village conducts an ongoing Shore Protection program to protect the coastline. While there are several projects anticipated within this program that will occur during the span of the undergrounding project, we do not anticipate much coordination will be required between the programs, since the beach renourishment project is not in areas undergrounding work will not be performed. Beach renourishment projects that involve truck hauls should be coordinated to reduce the impacts of additional traffic volume through the work zone. Miami-Dade Water and Sewer Department Watermain Replacement As discussed in the Data Collection section of this master plan, Miami- Dade Water and Sewer Department (WASD) does not currently have a formalized program for watermain replacement within the Village. However, at the request of the Village, they are willing to entertain the opportunity to replace aged watermains during each phase of the undergrounding program. There is currently no budget available to perform this work, however, WASD will review the Village’s proposal of replacement and consider adding it to the budget for the next fiscal year. This master plan’s recommendation is to focus on the known watermains consisting of asbestos cement pipe as requested by the Village. There are other watermains identified by WASD as being made of an unknown material. Secondarily, we recommend review of those locations to determine the most cost-effective approach to their replacement. Because physical investigation will be required for these unknown watermains, timing of their replacement may not coincide with the undergrounding program. If the County does develop a program of watermain replacement during the course of the undergrounding project, additional cost sharing opportunities could be explored through deferral of milling and overlaying activities until both undergrounding and watermain work is completed. 6.2.2 Traffic Impacts The sequencing recommendations for this program are also influenced by the desire to reduce traffic impacts to the highest degree possible. A detailed discussion regarding an overall traffic management plan is discussed elsewhere in this master plan but on a grander scale, the beginning of a mitigation plan for traffic impacts begins with sequencing individual phases. 55
