the streets in these neighborhoods are often played with numerous patches potholes and cracks and often lack an adequate street prone to shed water off the street section of the city i'm a ford assesses the condition of their streets on a yearly basis to determine which streets are most in need  us once we get into a neighborhood like this the typical conditions of the street includes a lot of potholes a lot of patching the street lacks an adequate crown to it which resulted in water ponding in the street section which further deteriorates the street so we get into a neighborhood like this the first thing we'll do is remove that pavement section as well as the subgrade soils underneath it and install new sand subbase underneath there along with drain tile and that sand some base in the dream tile with that helps to do is draw the moisture out from underneath that street section and help prevent that freeze thaw damage that we see and so prevalent in the state of minnesota on top of that st sub base section will install an aggregate base to help support the pavement section and on top of that will put the pavement with an adequate street krohn which helps to shed the moisture off the street into the curb and gutters at the side of the street the city began its street reconstruction program back in one thousand the late one nine hundred ninety s as part of the city's capital improvement program my name is john hiroshima's staff engineer for the city of maple with the public works department today we're in the hills and dales neighborhood which was reconstructed in two thousand and ten those concrete curb and gutters at the edges of the street helped to convey the stormwater order to the storm sewer system the catch basins the piping systems below the streets we do extensive as part of this project will design a full drainage system for the neighborhood including new catch basin for new piping and new infiltration basins and ponds another major thing that maple is well known for is a rainwater garden program as you can see behind me we guards as part of this project and these rainwater gardens help to draw water off the street section infiltrated down to the ground and help root remove excess pollutants and nutrients from the storm water runoff improving the quality of the wetlands and lakes in the neighborhoods water garden is basically a depression in the ground and when stall is called a curb caught in the curb and it allows the water runoff to come out of the street section get into these rainwater gardens and infiltrate down into the ground into the looser granular soils underneath they help to recharge the help to reduce the pollutants in nutrients excess nutrients and pollutants in the storm water runoff and also an extent aesthetically pleasing addition to any boulevards along with the pavement in the street improvements that we do in part of these projects that are expensive  these till the system underneath the street as well one of the first things will look at us will work with the regional water utility to determine whether or not there's any upgrades needed to the water system look at past break data and determine whether or not these streets are require replacement that water main the hills and dales neighborhood here required four thousand when your feet of water main replacement the sanitary sewer system is another thing we look at is part of these projects before the project occurs the sanitary sewer division will send a camera through the sanitary sewer main line and look for issues with the sanitary main such as cracking off that joints anything that would could deteriorate underneath the roadway and look to determine if there's any issues with their pipes anything that would require replacement as part of this project now the city is now transitioning towards a living streets concept on these reconstruction projects and what the living street concept incorporates is additional water quality measures by expanding the the rainwater garden program and by reducing the impervious surfaces like street pavement i'd also focuses on improving the biking walking conditions within the neighborhood by corporate ing additional sidewalks trails and bike lanes in the design the sidewalks are brand new they were installed as part of the twenty a lesson western hills neighborhood street improvement project incorporating water quality improvements narrowing street with tune reduce impervious surface and calm traffic and to install biking and walking features such as the sidewalk incorporating additional boulevard trees to help provide shade for the street sidewalk and help reduce
