    Lou Glatz asked about 1 year ago

    This property is zoned R-8.4.  The allowed uses and development standards for this zone are contained in the Residential Code (MICC 19.02).  In short, this is a single-family zone with a minimum lot size of 8,400 square feet.

    Bill G asked almost 5 years ago

    There are currently no variances being requested for the subdivision.  These types of variances would be reviewed with the building permits (at a later stage in the process); however, the City is not aware of any variances being considered at this time.

    Preliminary plans show treatment of runoff for basic water quality being proposed through a biofiltration swale and on-site storm filter. In the developed condition, upstream runoff will be intercepted by ditches and catch basins along the project frontages.  Please bear in mind that these plans are conceptual in nature only and will be more thoroughly reviewed with the site development permit.  You may also find it helpful to review the drainage report prepared by Blueline (dated 3/1/19) and provided with the submittal: http://mieplan.mercergov.org/public/SUB19-002/Submittal%201/DrainageRpt%203.1.19.pdf.

    The City has four residential zones, R-8.4, R-9.6, R-12 and R-15, allowing minimum lot sizes of 8,400 square feet, 9,600 square feet, 12,000 square feet and 15,000 square feet respectively.  A map of the city's zoning designations is available here: http://mercerislandgis.maps.arcgis.com/apps/webappviewer/index.html?id=f4464290a9b24d6496b43b39dea42a84

    In the East Seattle neighborhood, the are many lots that are below the current minimum lot size of 8,400 square feet.  These lots were created long ago, before zoning and minimum lot size requirements were in place.  In the blocks surrounding the East Seattle School site, there are many lots in 3,000-8,000 square foot size range, as well as many larger lots.  Because there are so many existing small lots, the density (i.e. the number of homes per acre of land) of these blocks is likely higher than what is proposed on the East Seattle School site where the lots will all be 8,400 square feet or greater.

    More information on the City's zoning requirements and lot sizes is available here: http://www.mercergov.org/Page.asp?NavID=368

    Alice asked almost 5 years ago

    The Engineering Division and the City's site inspector work closely with developers to manage impacts of construction on local streets and neighborhoods.  The applicant's plans for work that impacts streets and right-of-ways must be reviewed and approved by the city.  The City limits trucking and work within roadways during peak travel times, especially on major arterials. Use of the city right-of-way during construction also requires a separate permit. 

    The project applicant will also be required to evaluate transportation concurrency and to conduct a traffic impact analysis.  This will ensure that intersections near the project have capacity to maintain the same level of service and that the project will not create any safety or congestion issues.  In addition, the project must pay transportation impact fees to the City when the subdivision receives final approval. These fees are pooled to provide funding for the City to address transportation needs created by new development.

    The maximum lot coverage allowed for a house and driveway in the R8.4 zone is 40% of the lot size.  For an 8,400 square foot lot, the maximum lot coverage could not exceed 3,360 square feet.  There is also a 40% gross floor area maximum, which would provide for approximately 1,680 square feet for each story of a 2-story house (resulting in a total floor area of 3,360 square feet).  The gross floor area calculation does not include basements, so in this example, the house could include 3,360 square feet, plus a basement.  The house footprint would also need to fit within the required setbacks, which consist of 20 feet front yard, 25 feet rear yard, and 15 foot combined side yard (minimum of 5 feet on either side).  ~ Mona Davis
