Describe drainage flow paths(direction, location): <br /> Drainage flow paths will continue to flow to the northwest to enter the existing <br /> conveyance system along Sound Ave. Roofs will be connected with perforated <br /> tight-line connections. <br /> Are there Critical Areas?What are they and where are they located relative to your project?: <br /> No Critical Areas <br /> gop <br /> Task 2: Describe proposed project <br /> Describe your proposed project: <br /> The proposed project will subdivide the existing parcel into two lots and provide <br /> frontage improvements. Lot#1, to the north, will have a new house and driveway. Lot <br /> #2 will have the existing house and a new attached garage. <br /> How will your project change the existing condition?: <br /> The project will subdivide the lot into two separate residences with their own driveways. <br /> The site will remain landscaped with residential landscaping and not clear any native <br /> vegetation. <br /> Describe roofs, patios,driveways,or structures added: <br /> A new house with 2,119 SF of roof will be added to lot 1 along with a new 1350 SF <br /> driveway. Lot 2 will have a new attached garage of 800 SF attached to the existing <br /> house. The area in front of the new garage will be paved to connect to the existing <br /> driwownv nn Int nnc (cm) CF\ 0 <br /> How will stormwater be managed?: <br /> Stormwater from the roof areas will be managed through the use of perforated tight-line <br /> connections per BMP T5.10C. The lot 1 driveway will sheetflow to a yard drain to be <br /> connected to the existing system along Sound Ave. Lot 2's driveway will sheetflow and <br /> follow the existino driveways flow oath to Sound AvP where it will enter the system_ III <br /> Describe how the project will affect existing drainage systems onsite or on adjacent properties <br /> or both: <br /> The existing system will be largely unaffected as the net increase in impervious surface <br /> is low (approximately 1,300 SF) and the new roof areas will benefit from perforated <br /> connections. Drainage will maintain its existing pattern and no flows from the site will <br /> impact adjacent properties. A thickened edge has been placed on the driveway to the <br /> north to stop any flows from crossing to the neighboring property. <br /> City of Everett Public Works <br /> Small Project Stormwater Site Plan Report-Dec 2019 5 <br />
