 Good evening. Thank you for joining us for this virtual meeting for this Shanae Mendocino area sewer replacement project. I'm Mark Milan with Data Instinct and I have been asked to serve as a facilitator for the virtual meeting tonight. I'll be coordinating with Eric Robert who is with the city of Santa Rosa and is a supervising engineer for this project. I also want to introduce our Zoom host Roberta Atha. She is the administrative analyst with the city and will be coordinating questions and input from the public. Next slide please. Now I would like to turn it over to Eric who will introduce the rest of our presenters for this evening. Thank you Mark and thank you all for joining us. The purpose of tonight's meeting is to provide an overview of the project, discuss traffic and provide an opportunity for public participants to ask questions of our other presenters who I would like to introduce now. You heard from Mark Milan our facilitator for tonight and I'm Eric Robert supervising engineer for the city of Santa Rosa. We are fortunate also to have presenting tonight Emma Walton deputy director engineering resources for Santa Rosa water who will provide an overview of Santa Rosa water's infrastructure. Greg Dwyer associate civil engineer and project manager who will describe the project and its key components and Mike Van Mitty associate traffic engineer will describe the traffic control measures the contractor will be required to implement during construction. Also joining us tonight are Scott Westrope and Paul Lowenthal from the Santa Rosa fire department and Alex Kulik with GHD the design consultant for the project. They will be available to answer any questions you may have after you have heard our presentation. Next slide please. Eric this is Roberta I neglected to start the interpretation so I'm going to stop sharing for just a moment start that. Thank you you're all set. Okay next slide please. You may be wondering why this project is even happening and tonight we hope to address that in some detail for you. Overall the project adds great value to the community. It will replace aging sewer pipe reduce the potential for sewer overflows protect Pauling Creek and its habitat provide improved and safer access for routine inspection and maintenance and improve water pressure and flows. Overall the project will ensure your homes and businesses can depend on safe reliable sewer and water systems now and in the future. Next slide please. Regarding schedule I know it's only July but we wanted to give you a heads up of what's coming. The construction portion of the project will be sent out to bid in early August. We anticipate a contract will be awarded in early September with construction anticipated to begin later in the fall. You may wonder why construction is starting in the fall. As you will hear this project includes excavations to depths of 30 feet or more. To do this work safely and effectively groundwater needs to be at its seasonal low which is in the fall just before the wet season starts. This timing is important for the protection and safety of the crews or undertaking this activity and will help the project to move forward more efficiently. If everything goes as planned we anticipate that construction would be completed by the fall of 2022. So this is a two-year project. Next slide please. And to provide further details let's begin by hearing from Emma Walton. Emma. Thank you Eric. As Eric mentioned I'm Emma Walton the Deputy Director of Engineering Resources for the Water Department. The Water Department is responsible for maintaining a lot of infrastructure. We own and operate about 1200 miles of pipe and thousands of valves and manholes and hydrants. Next slide please Roberta. Given the magnitude of the infrastructure that we are responsible for maintaining we have a very robust capital improvement program. We invest about $25 million every year into our water and sewer systems to really ensure that we maintain redundant reliable systems ensure that we are being good stewards of the environment and meeting all of our regulatory compliance requirements and ultimately to minimize the risk to our community and to our community with a data driven approach to prioritizing projects. So we maintain many metrics and track many metrics and information about our systems including the location and the age and the condition of all of our assets and then we use this information to prioritize projects throughout the city. Next slide please. This is a map that shows the project location to kind of put this project in context. The Shinnate Mendocino area sewer replacement project is shown in the circle there. This is overlaid on a map of our entire sewer system and we undertake projects similar to this throughout the city and we systematically replace portions of our system every single year. So this particular project rose in priority as Eric mentioned in order to address aging and deteriorating infrastructure as well as capitalize on the opportunity to relocate the sewer trunk away from the banks of Pollen Creek and provide our maintenance and operations crews with better access. I'm going to hand it over to Greg Dwyer who is the project manager. He's going to provide an overview and provide much more detail about the specifics of this project. Thank you Emma. I'm Greg Dwyer the project engineer for this project. We're very excited about this opportunity to tell you about our project and to hear from you. The North Trunk Sewer is a primary trunk sewer that serves a large area of northeast Santa Rosa which is assessed from Shinnate Road, Parker Hill Road and Terra Linda Drive. Stream bank erosion along Pollen Creek has exposed parts of the sewer line over time. Although sections of this sewer were rehabilitated, repaired and improved throughout the 60s until 2005, the majority of this area of the city sewer collection system is over 50 years old and was constructed from materials that are no longer in standard use. Next slide please. Due to the age and location of the North Trunk Sewer alignment, inspection and maintenance of the trunk main is challenging and costly. This project will relocate the sewer alignment away from Pollen Creek to the road right of way. New water mains in Shinnate Road and Laminus Avenue will loop existing systems together, improving performance and reducing maintenance costs. The goal of the project is to replace the 12-inch trunk sewer that runs down Pollen Creek within the project limits. Work includes the removal and or replacement of sewer mains along Shinnate Road, Laminus Lane, Laminus Avenue, Strawberry Drive, Plum Drive and Mendocino Avenue and of course the abandonment of the trunk sewer down Pollen Creek. New sewer mains will be installed within the project limits and as shown in the figure, replacement of the trunk main is important so that the city can eliminate any potential future work along Pollen Creek as it pertains to maintenance access and also the potential for spills. Next slide please. This photo is looking east and is of a manhole to be abandoned along Pollen Creek near Strawberry Drive. What you don't see is just outside is Pollen Creek and it's very difficult to access this manhole to do any kind of maintenance. Next slide please. This photo is looking westerly along Pollen Creek near Strawberry Drive. Plum Drive is near the top of the hill. This manhole would be very difficult just to locate alone in the need of an emergency access to get to it to do any sort of maintenance or even you can't get a vehicle down there so you have to manually bring all your equipment down there which is a big obstacle. Next slide please. This photo shows a concrete block over a semi-exposed portion of a sewer main that crosses Pollen Creek near Lamedis Lane. This main will be abandoned as part of the project and as you can see you can imagine debris coming down this creek in higher flows could hit this line and create a spill hazard and an environmental hazard as well. Next slide please. This slide shows the limits of the project and the new sewer and water mains that will be installed. I want to point out that this map is also on our project website shenaitesuroproject.com Next slide please. The majority of the new sewer mains and all of the new water mains will be installed with open trench construction. This photo shows typical open trench construction which is similar to the work that you likely see around various parts of the city. This work will be plated at the end of each day. Next slide please. Because of the depth of the new sewer in a portion of the alignment along Shenaite Road and Strawberry Drive, trenchless construction technology will be used to install the sewer. This photo shows a typical trenchless installation and what will be seen for that construction. A shaft will be installed down to the required depth of close to 40 feet. Next slide please. This photo shows the trenchless construction technique that will occur down in the shaft. So this is the previous slide but looking straight down and you can see the workers down there working. A hole is bored out from a new shaft to another receiving shaft and then the pipe is pushed in at the required depth and grade. Next slide please. There are also two crossings below Pollen Creek that will utilize trenchless technology. This slide shows that technology which will be used at Shenaite Road in Mendocino Avenue which will be just past the driveway entrance to the coffee and at the east end of the project along Shenaite Road. Next slide please. Once the project is complete and all the sewer and water mains are complete the roads will be resurfaced. Lemetus Lane and Strawberry Drive will be completely reconstructed. Lemetus Avenue will have a full width overlay on the south of Pollen Creek. The remainder of the roads where trenching was completed will be paved over the trench width at a width of 7 feet. This includes Lemetus Avenue south of Pollen Creek. A lot of work was done developing a traffic control plan and detour plan between City Traffic Engineering and City Fire Department. At this point I would like to hand it over to Mike Van Mitty with City Traffic Engineering so he can talk to you about some of those efforts. Thank you Greg. I'm Mike Van Mitty Associate Traffic Engineer in Santa Rosa Transportation and Public Works Department. We understand that work zone traffic control will have significant impacts for many of you and I hope to explain what those impacts will be. As Greg described in the previous slides there are several different construction methods which will require different traffic control plans to accommodate the various activities. Some of the activities will allow the street to be opened outside of working hours while others will require continuous 24 hour closures for their duration. The work will be done in stages so the project will not have all the described traffic control measures implemented at the same time. Every effort will be made to accommodate pedestrians and bicyclists throughout the project limits. We do not anticipate any pedestrian detours or sidewalk closures. Next slide please. We will break up the project into two segments and describe their different traffic control strategies. Starting from Mendocino Avenue and working east to Humboldt Street and Belvedere Way traffic control will allow one lane in each direction. There will be parking prohibitions throughout this segment. There will also be turn restrictions for driveways and side streets throughout. Most turn restrictions will require drivers to turn right into and out of side streets or driveways. We anticipate significant delays at the intersection of Mendocino Avenue and Shenate Road during construction in that area. To accommodate construction activities in that intersection the east and west approaches on Shenate Road will reduce from three lanes in each direction to one lane in each direction. An optional detour will be available using Humboldt Street, Franklin Avenue, and Lewis Road. The second segment of the project traffic control is from Humboldt Street, Belvedere Way to Terra Linda Drive. The construction activities in this segment require one half of the roadway width. The traffic control will allow one way eastbound only traffic in this segment. There are some driveways and streets within this segment and specific instructions for those residents will be communicated to them. There will be a barricade closing the road in the westbound direction at Terra Linda Drive. Next slide please. In an effort to keep westbound Shenate Road traffic off of Terra Linda Drive and other local streets in the area westbound Shenate Road will be closed at Parker Hill Road. Local traffic only will be allowed westbound between Parker Hill Road and Terra Linda Drive. During this phase of construction the emergency access gate at the north end of Terra Linda Drive at Lake Park Drive will be open for northbound only traffic. In addition the ballards between Andy Way and Baldwin Way will be removed to allow northbound only traffic. Next slide please. This slide shows the ballards between Andy Way and Baldwin Way that will be removed to facilitate local northbound traffic only. This removal will be temporary and only during this phase of construction. Next slide please. This slide shows the emergency vehicle access gate between Terra Linda Drive and Lake Park Drive that will be opened to facilitate local northbound traffic only. This gate opening will be temporary and only during this phase of construction. Next slide please. During the westbound closure at Terra Linda Drive the official detour will be westbound Shenate Road to northbound Parker Hill Road continuing onto Stagecoach Road followed by a left on Fountain Grove Parkway and a left on Mendocino Avenue. Bicyclists going westbound Shenate Road at Parker Hill Road would be required to follow the detour. For those traveling westbound from Rincan Valley we anticipate drivers will use alternate routes like Highway 12 or Mark West Springs Road. Detour route maps will be available on the project website. Next slide please. Shenate Road is an emergency access route and we know there are concerns related to access for emergency vehicles as well as for evacuation routes. The design team has worked with the Traffic Engineering Division Santa Rosa Fire Department and Santa Rosa Police Department to develop contingency plans in case of an emergency. Construction would be halted and the road fully opened. If necessary Santa Rosa Police can reverse the westbound closure at Terra Linda Drive to allow evacuation westbound on Shenate Road. Traffic signal timing can be modified remotely at the signalized intersections on Shenate Road to allocate more time in any direction for any evacuation. At this time I would like to go back to Eric to continue the presentation. Thank you Mike. I want to elaborate on the point that in the event of a potential emergency we are taking a proactive approach. We will have the ability to shut down the project to facilitate any necessary emergency actions that may be required. We are working closely with Santa Rosa Police and Fire throughout the project in particular during extreme weather events such as red flag warnings. If necessary we will put the contractor on temporary suspension to evaluate these conditions. And now we would like to transition to the Q&A portion of our program. Mark can you give us some guidance on how this portion will be handled? Yes, thank you Eric. I would like to make sure that a recording of this presentation will be made available and put on the project website so others can see it later. Tonight if you have a question for our panelists please follow these directions. Select the raise your hand function in zoom if you have a question. If you are calling from a phone however you can dial star 9 to raise your zoom hand. You can also dial the microphone when it's your turn to ask your question or provide your input. We ask that you be courteous and keep to no more than two minutes or less so that we can allow as many people as possible to ask questions. If you hear your question asked and answered please lower your hand so we can get through as many questions and comments as possible. As we hear the questions Eric who can best respond. Now if you have a question regarding your personal sewer or water connection or your driveway access or any other issue specific to your situation, please contact us separately by email or phone for your personal specific questions. A phone number and email are available on the project website at shenadesewerproject.com and we will also post them tonight after your questions. So Roberta are you ready for the first participant to ask a question or provide a comment? Yes. So our first speaker is Cara King. Cara I'm allowing you to talk. Go ahead. Cara you can go ahead. Cara King you've been on mute. You can go ahead and make your comment or ask your question. Perhaps we'll go on to the next person and we can get back to Cara if she can raise her hand again. Okay the next speaker is Sonia Taylor. Sonia I'm allowing you to talk and unmuting you so go ahead and unmute your microphone and go ahead and make question or comment. Can you hear me? Yes. My name's Sonia Taylor. Hi Eric. Eric is familiar with me. I have a couple of questions. One of the presenters said that there would be 24-hour closures of some roads for the duration and then those details were not provided so I'm curious what that is. The detours out I live on LaMidas Lane. Right turn onlys in and out of driveways and roads with the closure of Mendocino and Shanaid essentially or the extreme difficulty getting through. I'm curious if coming out of LaMidas Lane onto Shanaid we will be able to turn left and I'm curious with regard to an emergency would a predicted high wind event be enough to shut the project down or would you want to wait to see whether it really happened. I'm very concerned about the evacuations having had to evacuate obviously in 2017. So those are my questions. Thank you. Hi Sonia. I will let my fan MIDI answer the traffic questions with regard to the emergency though. I can speak to that. We like I said in my little part of the presentation we when in doubt we are going to we have the authority and the contract is written in such a way that we will make the contract played over and open traffic up as necessary even the event of evaluating whether the emergency is significant or not. We won't wait till it occurs before we do that. So we have the discretion to take that action in the event of an emergency. Mike. Yeah thanks Eric and thanks Sonia for the question. So Roberta can I have you pull up slide number 22 please. Yes just a moment. Thank you. And while that's coming up Sonia I did we'll talk briefly about specifically your location but this presentation is targeted to a general audience and we'd be happy to discuss specifically your access and detour routes that you would need to take specifically to your location. So you know after the meeting please feel free to reach out to us and and you know we could discuss that with you. Perfect thanks Roberta. So actually I'm sorry can we go back one more to 21? My apologies. Paul in the meantime would you like to comment on the emergency question that Sonia raised? Yeah absolutely thank you Sonia. So yeah we have had a number of conversations leading up to tonight's community meeting and definitely do you understand the concerns of our community regarding evacuations. We have a plan in place right now to not only be able to proactively shut the job site down in advance of a significant weather event whether or not it's a red flag morning or something more of a critical fire condition that would affect specifically the lower elevations of Santa Rosa. A lot of the red flags we see are in the upper elevations but we'll continue to monitor those conditions. But we're also working on a plan to have the Know Your Ways Out update specific to this project and this location. So you'll see later on towards the end of the meeting and the question answers that there will be a website for Know Your Ways Out which is a an opportunity for our community to know all the different ways out throughout Santa Rosa. One of the things that we don't typically include in that are actual emergency evacuation access points. We will temporarily during this project have a map up that specifically shows those and we will potentially use them based on the conditions of an emergency. So plans are in place to use them if need be and have people aware of where they're at and that'll also play into how we message to the community in the event of an emergency. Thank you Paul. Yeah and Sonia so from this map you could see on Chinat Road between Mendocino Avenue and Humboldt Street we will have traffic open in each direction. However there will be turn restrictions so depending on the stage of construction we we will always keep access to side streets and driveways. However you may be limited to right turns in and right turns out. As we go east on Chinat, east of Humboldt Street at that point it's eastbound only one way. So any any access at that point would have to be from the eastbound direction. Thank you Mike. And the speaker is Kara King has been allowed her to talk if we can hear this time. Kara you can unmute your microphone. Hi can you hear me? Yes again thank you. Fantastic sorry about the first time I was double muted. I am just curious you mentioned that we want to minimize disruptions and most of the things that we heard about were traffic disruptions. I want to know are we gonna experience any sewer service disruptions and if so is there any way for us to be notified ahead of time and with how much lead time? Greg do you want to answer that question? Yes. Hi we will have a full-time inspector on the project site at all times during construction. We're not just gonna shut down the sewer service or your water service without plenty of notification so you'll be notified along the way it'll be very brief while they make the connection of your sewer lateral into the new main and then so that way you can plan for it. And if you don't have a sewer lateral coming from the new sewer if you're not involved in that then would would service be affected? Greg? So I'd like to hand that to Cy Penry with the city technician. Hello Kara thank you for your question also. Yes I'm a civil engineering technician for the city of Santa Rosa. Sewer lateral interruptions are very brief on construction sites. It's the guys that are making the tie-in when they remove your old lateral connection and hooking up the new one that only lasts for about 15 minutes to 30 minutes when that tie-in is being made. Other disruptions when it comes to water if you're in the area of the new water installation is at times we have to make tie-ins and those tie-ins usually run in the vicinity of approximately four hours but there's a great advanced notice on that and for areas like businesses that need to be kept in water we supply a water tanker truck for that. So if you're a resident so you could be about water for half a day or in the range of half a day. Thank you Cy. And there are no more hands raised as far as the attendees. Mark you're muted. Okay well I would like to thank everyone for participating tonight to continue to stay informed and get information on the project visit the project website at shenatesewerproject.com. Roberta could you maybe put that slide up so people could see that that'd be great thank you. Thanks Mark. There is a link on the website to sign up for construction update details or you can send an email to us at info at shenatesewerproject.com and we will put you on that list. You can see on the screen there is also a construction hotline phone number 707-385-1239. This is for your use once construction starts. If you should have questions or an issue near your property and to be prepared in advance should there be an emergency of some kind as Paul mentioned please visit www.srcity.org forward slash know your ways out. Again construction will begin later this year in the fall and we will continue to keep you informed as the project progresses. With that thank you all for joining us tonight and for your participation. Good night.
