DISCUSSIONS a. Receive and discuss a presentation regarding the City of Baytown Storm Water Master Plan. Director of Public Works and Engineering, Frank Simoneaux presented the summary of results from the 2020 Master Drainage Plan. He introduced Mr. Al Flores and Mr. Jacob, representatives from Dannenbaum Engineering, the consultant firm who completed the study, as well as introduced Mr. Irwin Burton, the City Engineer, and Mr. Jesus Fabela, Drainage Foreman. Mr. Simoneaux stated that the objectives of the study were to understand the existing drainage system and patterns, put that into a computerized model to further understand the effects of different types of improvements, and how that would affect the city's drainage, and to identify drainage improvements that could be implemented to improve drainage within the city. He noted that prior to 2020, the City's CIP did not really have any drainage projects included and further noted that most of the master plans that he has seen focused on high-level studies which just looks at regional projects and detention, but he instructed Dannenbaum Engineering to provide recommended improvements that would be more usable and could translate easily into capital improvement projects, which they did. City Council Work Session Minutes March 11, 2021 Page 2 of 3 Mr. Simoneaux stated that the evaluation process included a meeting with city staff, whereas, the areas of town that were known to have recurring flooding problems were identified. He stated that during the year 2020, the Drainage Ordinance and the Floodplain Ordinance was updated, which changed some of the work Dannenbaum had to do, and they did without charges to the city. He stated that twenty of the twenty-one systems reviewed require some level of improvement. Mr. Simoneaux stated that West Baytown, Danubina, Fayle, James, and North Alexander were all identified as having recurring drainage problems. He stated that each of the twenty-one systems were categorized as two different priorities based on the level of ponding with a two-year storm event. He stated that if the ponding was greater than one foot beyond the right-of-way with a two-year storm event it was categorized as a high priority system, the priority systems had from zero to one foot of ponding within the right- of-way, and the lower priority systems did not have any ponding in the right-of-way. Further during the presentation, Mr. Simoneaux stated with regards to the high priority system, there were three areas identified, a large area in Danubina and two (2) adjacent areas in West Baytown. He stated that Danubina was by far the largest and most expensive system for improvements which was broken into three different phases with the first phase being the Harris County Flood Channel Improvements that includes a detention pond and trunk line. He noted that this area was submitted for funding under CDBG last fall; however, during the process of the master plan there were no final numbers. He noted that the grant was submitted less than the cost and if approved there would have to be some partnership opportunities with Harris County, especially considering the part of the improvement that includes their channel. Additionally, he provided maps demonstrating what would happen when improvements are done. He further noted that the maps were only estimates being in the model stage, but more accurate data would be available from the survey after the final design. With regards to West Baytown, Mr. Simoneaux stated that there were two drainage areas with improvements broken into different phases with Phase 1 being the trunk line going down Oklahoma. He noted that this area was submitted for funding under Harris County Partnership Grant applied for in January and staff was waiting on a response, which if received, would be an approximate fifty percent grant. He went through the other priorities in the same manner as the previous by providing a map of the estimated improvements. He stated that the James area drainage improvements include the detention it shared with Danubina and that the cost was included in the detention required for that area. He stated that although the tension would be located in the same place, staff would estimate how much was needed for that particular project. Additionally, he noted that other improvements included some strong drainage pipe. With regards to the Narcille area, Mr. Simoneaux stated that there was a detention system shared with the Vine area that would need some channel improvements and storm drainage pipe. He stated that the North Alexander area needed detention and storm drainage improvements and was submitted under a CDBG grant last fall, in which staff City Council Work Session Minutes March It, 2021 Page 3 of 3 is waiting for a response. He stated that the West Main area needed detention and storm sewer improvements and that the Rollingbrook from Garth to Main area was much improved under the proposed conditions. Additionally, he stated that the North Main at State Highway 146 needed detention and storm sewer upgrades and noted that the remainder of the systems were listed as low priority systems. In summary, Mr. Simoneaux stated that there were twenty projects identified with three being high priority, seven being priority, and ten being low priority. He stated that all systems proposed were storm sewer improvements that would capture the five-year event and further stated that the hundred -year event would be contained within the right-of- way. He stated that the next steps were to identify funding sources for all of the projects and seek opportunities for right-of-way. Lastly, he stated that it would be better to purchase vacant land now for the detention before it develops and further noted that staff would coordinate with the Hams County Flood Control on any project. Council Member Alvarado inquired where and if the Mississippi Street trunk line was included in the Master Plan and further noted that it was not included with the grant for the Harris County. In response to Council Member Alvarado's inquiry, Mr. Al Flores with Dannenbaum Engineering stated that the area in question was on the West Baytown drainage improvement. Council Member Alvarado further commented to continue and concentrate on the Oklahoma trunk line as work was already done in that area. Mr. Simoneaux stated that he believed that the mentioned trunk line was in Phase 2 of the proposed improvements, but he would verify. Council Member Lester noted that District 6 was approximately two-thirds of the overall general map and the numbers associated with the area was huge and typically meant that they were going to get pushed further and further back. He also noted that Districts 6, 2, and 1 were at the bottom end collecting the water from other areas. In response to Council Member Lester's comment, Mr. Simoneaux stated that staff would seek outside funding to assist with such issue. b.
