The proposed residential use and density (6.5 net dwelling units/acre) are consistent with the existing Low Density Residential (LDR) zoning and the City's standards for development in the LDR zoning district, where a maximum of 10 dwelling units/acre is permitted. Duplex dwellings may be permitted only on corner lots in the LDR district, thus duplex dwellings would be permitted on one of the proposed lots — lots 6. The proposal includes the construction of Kalmia Street and 43rd Street. SITE AND SURROUNDING CHARACTERISTICS The site is within an established Springfield residential neighborhood. The property is located between 44th St, and 431d St. The northern, easterly and westerly property lines of the proposed subdivision abut residential neighborhoods. The mapped soil series is #97 -Newburg - Urban Land Complex. 5.12-125 Tentative Plan Criteria The Director shall approve or approve with conditions a Tentative Plan application upon determining that all applicable criteria have been satisfied. If conditions cannot be attached to satisfy the approval criteria, the Director shall deny the application. In the case of Partitions that involve the donation of land to a public agency, the Director may waive any approval criteria upon determining the particular criterion can be addressed as part of a future development application. A. The request conforms to the provisions of this Code pertaining to lot/parcel size and dimensions. Response: The proposed lots fronting the east -west streets meet the 4,500 sq. ft. minimum lot size and the 45 -foot street frontage requirements established by SDC. The applicant is requesting a variance for lots 7-11 from the 60 -foot street frontage requirement for lots fronting the north - Page 1 of 3 south streets. The applicant is also requesting a variance from the minimum lot size for lots 9-10 from the minimum lot size. These variance are justified in order to efficiently develop this property to its highest and best use. Also, because of the need for housing in the City of Springfield and the City Council's Policies to create more housing, these variances can be approved. B. The zoning Is consistent with the Metro Plan diagram and/or applicable Refinement Plan diagram, Plan District map, and Conceptual Development Plan. Response: The property is zoned Low Density Residential (LDR). The Metro Plan diagram for the subject property is LDR. C. Capacity requirements of public and private facilities, Including but not limited to, water and electricity; sanitary sewer and stormwater management facilities; and streets and traffic safety controls shall not be exceeded and the public improvements shall be available to serve the site at the time of development, unless otherwise provided for by this Code and other applicable regulations. The Public Works Director or a utility provider shall determine capacity issues. Response: a. Water: The proposed development is within the Springfield city limits and will receive water service from the Springfield Utility Board (SUB). There is an existing 8" waterline in Kalmia St. An 8" waterline will need to be extended up the new streets to provide water service and fire protection. b. Wastewater: There is an existing 8" wastewater line in Kalmia St. which will service the entire subdivision. c. Stone Drain: There is an existing storm drain line in Kalmia St. which will provide service for the subdivision. The storm drain system will be designed to not exceed the pre -development flows. d. Streets: The proposed Kalmia St. construction will consist of a 36 -foot wide paved section with a 5 -foot curbside sidewalk and a 50 -foot right-of-way east of 43rd St., a 28 -foot wide paved section with a 5 -foot setback sidewalk and a 50 -foot right-of-way west of 43rd St. The proposed 43rd St. construction will consist of a 20 -foot wide paved section with a 5 -foot setback sidewalk and a41 -foot right-of-way. The proposed Jasper Rd. construction will consist of a 32.5 -foot wide paved half section with a 5 -foot setback sidewalk and a 40 -foot half street right-of-way. The Springfield Fire Department has reviewed the proposed layout and has endorsed the design. D. The proposed land division shall comply with all applicable public and private design and construction standards contained in this Code and other applicable regulations. Response: See Response to part C. E.

It is located on the north side of Jasper Rd. east of 43rd Sl. and west of 440 Sl. The site is an operating nursey with two existing homes and consists of about 1.7 acres. EXISTING HYDROLOGY The site is relatively flat and portions of the site drain to the south. PROPOSED HYDROLOGY The proposed drainage system of piping the proposed drainage to a proposed detention pond on the east side of the subdivision on the north side of the proposed Kalmia Sl. The pond was sized using the TR -55 unit hydrograph storage indication method. The proposed detention pond has an overflow outlet at elevation 489.5. The proposed outlet will drain into an existing 10" storm drain in Kalmia St. The pre -development flow from the site is 0.55 c.f.s. The post -development flow to be directed to the detention pond is 0.85 c.f.s. The total proposed flow after routing through the proposed detention pond is 0.53 c.f.s. Attached are the following: 1. Pre -Development 10 -year flow (TR -55) 2. Post -Development 10 -year flow (TR -55) 3. Routed Post -Development 10 -year Flow (TR -55) 4. Stage -Discharge Curve 5. Stage -Storage Curve 6. Hydrograph of 10 -year Pre -development 10 -year Post -Development and 10 -year Routed Storm CONCLUSION Based on my calculations and the proposed drainage system is sized properly and will provide the necessary flow control.
