construction work in the downtown area here's the zoomed in view of the district 3g district 3 and 6 where the majority of ninth amendment priorities along with the orange for traffic okay. so next, i want to go over the application process all applicants are required to apply 5 days in just an advance a plan checker will gather work or information is there an associated excavation permit is extra staff available to oversee the night time work and for all capital projects as well as the repair projects one hundred 50 foot radius for the night work permits the night time work is

to adhere the applicant is required to follow all requirements notification letter must include the company name who's performing the work and dates and times when the work occurred and the location where and the 24/7 contact in the case there's concerns what is public works roll public works they inspect the contractors to insure the public is safe and the project monitored between the hours of 8 to midnight inspectors are required to evaluate the scope the same as authorized with the permit and make sure the site has been

delineated with cones and signs carefully admonishment the sidewalks so pedestrians can use the sidewalks and appropriate lighting public works inspections assure there's no vehicles at all possible and shouting and yelling by contractors and where the contractors needs to work past minority they can only use backhoes and drillers and excavators and just a second hammers and loaders so i wanted to show you a few photos of ninth amendment work the contractors site to assure the safety and the surrounding site in the background hopefully, you'll see the

posters with the signage here you see the proper delineation of the property site to use the cones and here's another photo of the construction work emergency repair work at night to what happens after midnight well, after midnight you can contact the patrolling police under the police code the police do enforce the night time ordinance here's the phone numbers of the applications and if you find a contractor working without a permit call 311 to issue a complaint so that that concludes my presentation. and i'm here to answer any questions you might have. >> i did have a question on the notification i know you said the company is required to novice

within one hundred and 50 radius what does that look like and they on have to apply 5 days in advance. >> they do it it gives them a shorter amount of time the 5 days is more for emergency or repair work where there's time to apply for a ninth amendment permit. >> what percentage in the downtown area are giving thirty days in advance vs. 5. >> it encompass 5 percent the rest are repair. >> so close to 70. >> close to 70 percent are repair. >> so 70 percent of the ninth amendment construction permits that dpw issues are for emergency repairs. >> emergency yes. >> what do you mean.

>> if we look at the other slide i showed you before let's go back to the map that's not a whole lot of night permits we're talking about. >> when you say capital projects are talking about san francisco projects. >> i'm talking about pg&e and maybe long term projects that are planned out to say. >> only they're required to do thirty days in advance office development they only need 5 days. >> they normally do more we try to hold it to people that utility companies that have to repair gas breaks. >> those permits they're not for emergency repair they're doing long term work. >> there's long time work and

for those long time projects it i see on the map we haven't differentiated but they have a minimum of thirty days for example, pg&e they send up to 6 months i'm saying thirty days is the minimum. >> we're not hearing about pg&e but we're hearing about the residential and office development and their night time permits those are not emergency that's part of their construction schedule. >> okay for those projects those are the long term projects we're rigging a longer - >> thirty days. >> yes. >> not just city projects but a long-term office so if they apply thirty days in vandals is it the moment they send out the application. >> that's a minimum it's thirty days the six days is for emergency in many times the

emergencies they didn't have the time it's immediate that's our goal and . >> and for the letters or the visitations what form do you expect that to go to residents. >> we expect mailers this postcards and it's a true emergency we'll activate it immediately minimum 2 emergency contacts. >> actually our residents appreciate there's a contact number when they get the notification so we real appreciate the process that expelling is doing thank you so much. >> okay. thank you. >> so next, we do have through the chair dph and june winning

trophy. >> good afternoon, everyone. i'm june i'm an epidemiologist and the acting manager of the various regulatory programs in environmental health at the health department including the work on the noise enforcement and regulation what i'm going to just show you in this brief presentation put the concept of noise into health context for you then talk about the work we've been doing at as a city to collaborative with all of the many agencies to try to reach some sort of holistic view

of how we should deal with the competing problems and issues that everybody's xhort so first of all, as i think everybody in this room realize the health effects from noise are there's some objective active ones and subjective ones for more san franciscans the levels of sound that their imposed to an a regular basis and even if they're living next door to construction sites are not going to be higher enough or prevent enough to cause hearing damage on the left of the slides the hearing loss concern hates not a hard and fast number for occupational it's as cal osha

has a limit of 90 decimals for 8 hour explorer that's if a worker is standing and users a piece of equipment like a circle last year sander for 8 hours straight they were going doing that for 8 hours and one minute cal osha requires some sort of additional measures national institute for health and safety has a more modern perspective their level is 85 decimals for an 8 hour exposure so that is to say the hearing loss we know for sure really there is very few circumstances in the city where citizenry are

xoensz to levels that cause hearing damage of course, it is a real objective and measurable health that in and of itself leads to cardiovascular changes that kansas city can do into legitimate and measurable physical loved one responses now awe known as is a medical term and it is defined by the experts in the noise and sound like field as the relationship between aversion to noise like cardiovascular or changes they have a noise that is highly annoying in which a twenty-four hour 0 vafrnl exceeds 24

decimals so the levels in the city over an average are probably not ever going to exceed 55 but that doesn't make a difference when our talking about sleep disturbance and if you're sleeping for one second someone drops a big concrete thing on the ground and he hear it fall it whacks you up and your babe up that disturbs our sleep there's a lot of elements if what we think about when we're trying to understand what the health affects of noise and sister-in-law are they depend on not only the level but the duration and the in the matter objective some people get annoyed new year if they're in a elevator with tiny backward

music and others don't notice it there's clarity in the ideal world we don't have those you know loud disruptions at fit that can led to sleep disturbance from the health department's prospective we are trying to change the way we talk about noise and sound in the city from this invented understanding and reception to a public health perspective our mission so protect the public health so part of our job in the city is to weigh the balance between public safety as a public health measure and the health effects of something that can cause a real issue on a population level so the best we can do is sort of

try to ask those 3 questions here does the noise create a negative experiment tilt inflicted on the public an identifiable way of separating user e yours ourselves from the noise as something that be subject is there evidence of a harm for which causation she can be at the population level that comes back to the occupy your occupation 0al standards and the things we know about sleep disturbance and finally do the health risks with the internal limits with the rooiks or a sound limiting it during the day having you have here sorry

there's an ambulance there that's a public safety measure it is not great if you're sleeping at night and hear an ambulance outside, however, it is a public safety thing you don't want the ambulance to be just running quickly through the streets without letting people that are on the centers know and you want them to be able to get to their designation quickly you have a picture this was from when they moved the earthquake houses on the took up right this is something that happened during the day and they had to block off the whole street there was a lot of activities i think i'm not familiar with what discussions went on h how they weighed the decision whether it made sense to do it

at night or during the day it's a nice illusion of the different elements with your trying to look at who is around, how many streets do i have to block off and people are disturbed during the day too so i'll give a quick history in 1972 the federal control act was impacted and as sort of part of that month memento that was when san francisco's noise ordinance was first be impacted there were a couple of minor changes shortly there after and noise regulation kind of went off of everyone's radar for awhile in 2008, here in san francisco we repealed and replaced many of the sections almost all the entire law and

modernized it was a groundbreaking effort to try to become better at how we address this balance of living in an urban environment where sound is part of the fabric of our world and the potential health effects that are associated with loud sounds like and disturbance so since 2008 a few changes have been made noted many we've been implementing the noise ordinance as you do it in the code today and what we found is that it is a great law that has some imperfections i know that all of you hear from our constituents that there are problems and with our constituents being you know

both business and residents commercial construction we're all constituents purpose of the work group was to 30 fold number one to have a look at how we all were implementing the noise laws in the city to look at the noise law and try and see if there were changes that needed or could be made and then also to draft the uniform guidelines and how to cooperate you've heard from she didn't have dph how they implement in their will ninth amendment permits and you'll hear from dbi 0 how they implement the noise complaint and in addition there are certain types of noise that come to the health department and noise to the police department and there are many that guess to

311 you'll hear from. >> can i ask a question through the chair so this was the purpose of noise work go up what came out of it. >> what came out of it is right here we came up with conclusions that are basically that with the diverse and active population proximity of homes to businesses and urban traffic san francisco, california be a loud place we agreed that noise is subjective quality and sound is not necessarily high enough to cause hearing damage but as far as the next steps i think your question. >> i don't think i needed a workshop to come up with with

it. >> i think you understand we move slowly but deliberating it's a lot of agencies that are named in not only in article 29 which is the part of the police code that governs noise but the sound like is mentioned throughout city code and very difficult to put apart i'm proud of the work that we did take assemblyly long to do to draft right now in draft state a citywide guidance to the law it is a mutually understood guidance for the exciting e exist law everyone has different interpretations of how to measure the differences you've heard about the 5 decimal differences what's our starting and ending point and where you measure it we want to be

consistent it's not clear within the existing codes and we're finalizing with 311 a motivation to get a handle very clearly on who is responding to the sound complaints, when and how long it is taking them to be responded to and make sure that nothing gets lost and thou ends up in our offices with a frustrated person and finally cancerous the amendments to be existing law article 29 and other aspects what we really want to do is have understand this community level city family level perspectives and reach out to the stakeholders how we should be handling the noise in

the city we would like to have a genuine stakeholder process that can move forward with counsel with a solution that improves on our existing law which is already pretty great by try there's also room for improvement. >> i have a couple of questions i know that dph doesn't monitor ninth amendment do you help the departments so monitor and we've taken that on it is something we have a noise control officer that sits in the health department and who has made himself available to all of the departments to train on how to use the sound level 3450er9s one of the simple changes to the existing code is right now in

the code it requires a type of one sound level meters that's a really expensive pieces of equipment it doesn't take a ton of which you are to operate but it's expensive we don't have a ton of them in the city we want to change that to allow a type two 10u7b8d level meter that will make the availability of enforceable measurements a little bit easier and would the primary departments you recommend effect the it will be dph i'm sorry dpw has inspectors that do offsite monitoring. >> i - yeah.

>> and do you have do you know how many ninth amendment complaints have been recorded. >> i don't that's one of the goals with the 311 process to have more uniform tracking to answer that question. >> so we're working with 311 to upgrade our system what how do we collect that data. >> i think my colleague is going to explain that. >> great. thank you very much so we do have bryan from sfmta here as well thank you and then our final presentation will be dbi and hello chair weiner i'm bryan with the sfmta the streets division today, i'm going to talk about the blue blocking and

our role with respect to issuing permits so my agency works with dpw and muni and other agencies when permitting the streets and walkways one of the tools we provide is called the blue book regulations for working in san francisco streets excuse me. this document covers a wide range of giles and rules and regulations to allow the contractors to work as well as the city crews and the utilities it identifies the permits required to work on city streets and provides the guidance for restrictions and provides lane and combleer requirements and the destruction i construction for traffic control and provides guidance for bicycle routes and schools if contractors are not able to

follow the restrictions rules and regulations in placing in document or building the construction is site it needs additional escape above and beyond they'll ask for a traffic permit we'll look at the site and get the conditions of the site and the hours they're requesting and see if we can issue a permit for them there are many instances we're not able to let them do everything they want to they want to take a street it's 4 lanes and reduce it to 2 until the traffic is stuck there's golden gate and transit and other areas in addition to the commuters sometimes a they'll need to disputing shut down a sidewalk for concrete pour and it may not work well on paper

so especially, when our near union square or the transbay terminal where we've encountered did the with pedestrians coming through if we can we'll issue a permit to allow concrete pours and majores vacationed to occur but we can't also do that so there are 4 situations i wanted to talk about briefly that come up that will illustrate what i'm talking about earlier lynn talked about the streets of major importance listed in table one of the blue book and some are shown in map a those streets are restricted from 7 to 898 or 9:00 a.m. and 3:00 p.m. to 7:00 p.m. so if you have to work with the constraints you can only do is

concrete pour from 9 to 12:00 a.m. so on a case by case basis we'll see is it possible to deploy 50u6r78d officers to assist with the green time and override traffic lights but for tenth street it's noticing not going to work so in ass instances we'll ask the contractors to reduce tare pouring and look at it pouring on a weekend sometimes to midnight which brings us where we are today and second category we have very difficulty with our cable cars and f line we can't shut those down during the day

so most of the work in the vicinity typically occur from one a.m. to 5:00 a.m. delivery of oversized loads they'll bring in a large pieces of equipment or a temporary structure and it exceeds what's called a legal load in california i can get special permits many times it will recycle the movement of the vehicles and liquor store we'll match it because we have to so when the deliveries show up to midnight on a instance where a delivery is occurring in an unoperative time so those are the conditions in which we do

encounter noise that's mostly when i wanted to talk about i have a graphic i was asked to prepare projected into sftv if possible i'm sorry the text didn't show up this is an image of a typical be hypothetical building site it represents the property being built and permits within the area are controlled by dbi the blue area is both within the sidewalk and the parking strip it is issued as a street space permit to allow the contractor to allowing provide the blue minimum path through this site it will be widower depending on the site for example, market street may not work
