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 but for vertical or construction we'll need to get a special street permits or additional street space i thought that might be helpful to talk about where the agencies have a role with the vertical construction. >> thank you. i want to say this part of the city ear building mixed use neighbors a lot of the neighborhoods are considered streets of importance so i appreciate that sfmta is looking at the borders on a case by case basis to understanding the mixed use and a half of the area so thank you. >> thank you. >> so new dbi?

>> good afternoon, supervisors my name is patrick i'm the chief building inspector at dbi here to talk about our policies and procedures. >> construction work at night is covered under san francisco muni code allowable working hours we know are from 7:00 a.m. to 8:00 p.m. it's important to talk about the 5 decimals over ambiance what is essential means is that those projects can navigate work that is within this 5 decimals above ambiance that's the normal

background noise that's during the day it
