The property is located to the northwest of the intersection 104th and Ethel Street in the civil township of Clay. The site is currently zonedR3 residential and forms part of the Northwest Quarter of Section 12, Township 17 North, and Range 3 East of the Second Principal Meridian. Madison Woods is a nine lot subdivision located within the Town of Home Place, Indiana. The Town of Home Place is between Carmel to the north and Indianapolis to the south. The site contains 2.25 acres of property. There is an existing home located on Lot 33. The property has several out buildings located on Lot 33 which will be demolished at the start of the project. The Property is owned by Carmel Development, LLC,. SANITARY SEWERS Sanitary sewers are provid'ed by Clay Township Regional Waste District located at 10701 N. College Avenue, Suite A, Indianapolis Indiana 46280. Sewer availability for 9 lots is being requested in writing and preliminary permit information has been exchanged. The average daily flow for the 9 lots is 5,580 gallons per day with a 4.5 peaking factor the peak flow is 25,110 gallons per day. The District has verbally stated that they have capacity for the developments sanitary load. All sanitary sewer lines will be a minimum of four feet deep and constructed of PVC SDR 35 sewer pipe. Gravity sanitary sewers are available to connect to along 104th Street and Ethel Street. The existing sanitary sewers flow north on Ethel Street and west on 104th Street. It will be necessary to have the homes along 104th Street to be serviced from the existing sanitary sewer on 104th Street with standard sanita,ry taps. The Existing manhole on Ethel Street stops short of 104th Street and the Madison Court Cul-De-Sac will tie into this Manhole. 'The existing manhole has a top of casting' elevation of 829.12' and an invert of 821.37'. The average ground height on site is approximately 828.0'; this allows for nearly (6.63') feet of fall. The 280' connection should not be a problem using a slope of 0.45010 (1.26'). The proposed top of casting for the Manhole on Madison Court is 827.25' and the invert will be 822.63' WATER SUPPLY The Indianapolis Water Company (IWC) will provide water service to the property from their existing lines. The engineer has contacted IWC and supply will not be a problem. The homes along 104th street will be serviced by tapping the existing main. The extension of the water main will occur along the proposed cul-de-sac. A 6" water line is E:\Land Projects 04\Homeplace\ENGINEERSRPT.doc Page-3 I I I I I I I I I I I I I 'I I 'I I I I proposed from the connection on Ethel to the hydrant are located on the lot line. The remainder of the pipe will be 3" Polyethylene and will end with a blow off valve. All water mains will be AWWA approved pipe and conform to IWC standards. The pipe will be laid at a 4-foot depth. Typically water service will, use a double valve pit for two units. All of the water components in the project will be maintained and owned by the IWC. Location of fire hydrants will be spaced no greater then 500 feet and their location approved by the Local Fire Chief. STORM WATER DRAINAGE Currently the site is undeveloped and drained via surface flow to a legal drain. The site has a curved contour rising from 104th Street to the northern property line. There is an existing flow'between the existing lots numbered 33 and 32. The proposed cul-de-sac will slope from Ethel Street down to the proposed curb inlets set into the north and south sides of the cul-de-sac. Anunderdrain will be extended north from the northern curb inlet for any existing ground water flow. The sewers will extend south to 104th Street and then connect with thelegal.drain to the west of our site. (See Legal Drain Map) The detention for this site will be handled by means of an over sized connection pipe with an orifice plat over the outlet and the back yard swales. A more detailed drainage report will be sent for the Town Engineer to review. The soils for the site are Miami and Crosby Type Clays, which have poor subsurface drainage characteristics. The site has good elevation changes across the site ranging from 823.50' along 104th Street to '833.0' in the northwest corner of the site. All of the streets will have adequate inlet capacity to handle a 1 O-year storm intensity. Typically the-back yards will drain to ditch inlets which will connect to the street drainage system and then to the legal drains. Adequate easements have been provided for the installation and servicing of these storm sewers. The detention will be designed to handle the 1 OO-year storm event while releasing the storm water at the 10 year undeveloped rate. STREETS AND INFRASTRUCTURE All of the nearly 0.05 miles of street proposed for this project, are to public streets and will be dedicated to the Hamilton County. The streets will be constructed to the Counties current standards and will be maintained by Hamilton County. The proposed E:\Land Projects 04\Homeplace\ENGINEERSRPT.doc Page-4 I I I I I I I I I I I I I I I I I I I street will connect to the existing Ethel Street. The street will have a platted fifty-foot wide ri.ght-of-way with thirty feet of street and the cul-'de-sac will have a 38' radius and a 50 right-of-way. The streets will use roll curb and gutter and will be crowned at 2% slope. The curb will taper to match the existing streets which do not have curb and gutter. The proposed surface will be asphalt and match the Hamilton County Standards. The proposed street name is Madison Court has not been approved on the Preliminary Plat, but will be submitted to the Town for their approval. The proposed cross section of the street from the centerline will consist of 13 feet of asphalt pavement, 2 feet of curb and gutter and a20 grass buffer. Typically the utilities have a 15 foot easement on the outside and/or within the adjacent right-od-way. This will consist of Electricity, Telephone, Gas, Cable, Sanitary Sewers, Water Mains and Storm Sewers. LEGAL DESCRIPTION LOTS NUMBERED 31, 32 & 33 IN LITTLE FARMS ADDITION TO HOME PLACE, HAMILTON COUNTY, INDIANA, AS PER PLAT THEREOF, RECORDED IN DEED RECORD 109, PAGES 50 & 51 IN THE OFFICE OF THE RECORDER OF HAMILTON COUNTY, INDIANA. SUMMARY There is a multitude of supporting information on the viability of this proposed subdivision. The Current zoning is R3 The surrounding homes are consistent with the proposed project. The Primary Plat for Madison Woods prepared June 2004 The remaining questions for this development will be answered during the normal plan development process, which will commence once the Primary Plat is approved. The Drainage Report will be the first thing addressed, then the sanitary design and finally a completed set of construction documentation will be prepared for review by the town and all of the utilities. After the Technical Review is complete, the plans will be revised and permits will be filled. Construction is not anticipated to begin until late summer. We formally request that this subdivision be allowed to bond for improvements so that the secondary. plat can be filled and approved.
