Dean Civil Design Incorporated 15104 Cantrell Road Little Rock, AR 72212 NUMBER OF LOTS: Phase 3 - 12 lots Phase 4 - 10 lots One Open Tract Lot FT. NEW STREET: 834 LF #1 River Mountain None This proposal will create an'additional 22 single family lots in the Heatherbrae Subdivision which was initially final platted in 1987. Approximately, seven finished lots from previous phases remain vacant at this time. A. PROPOSAL RE UEST: To create 22 new single family residential lots in two phases as an extension of the existing Heatherbrae Subdivision. Glenn Valley Drive will be extended to the west. Heatherbrae Court and Glenstone Drive will be developed running north to south. B. EXISTING CONDITIONS: The land is flat, heavily wooded and covered with dense underbrush. Existing phases of Heatherbrae Subdivision are immediately adjacent to the east and south. Glen Valley Drive stubs into the site and will serve as access to the site. The Gooch Drive residential neighborhood is located to the west and south. October 10, 1996 SUBDIVISION ITEM NO.: H Cont. FILE NO.: S-717-F C. NEIGHBORHOOD COMMENTS: None to date. D. ENGINEERING COMMENTS: PUBLIC WORKS COMMENTS: Continue sidewalk on Glen Valley to intersection. Drainage easement shown on the west property line must contain all flows off site shown to be in excess of 453 cfs, staff recommends that due to flows in this drainage that the easement shall be an open space tract and not contained on individual lots. If the drainage is to be contained in an open ditch, 4 foot chainlink fencing will be required adjacent to drainage easement to restrict access from small children, safety concerns raised by the other existing drainage ditches in the City has caused this to be a policy adopted by the Board of Directors. Ownership must be established to provide tailout of the drainage to the north to properly intercept the existing floodway. This subdivision cannot begin construction until the engineering plans are approved with proper development permit, NPDES, and grading permits due to past problems with Phase 2. An above ground drainage easement will be required on Phase 2, 3, and 4 lots to accommodate the major storm event as required by City Ordinance. This major drainage easement will be graded and restricted as to use by lot purchasers concerning construction of fences, landscaping and fill as required by Ordinance. The pipes and ditches planned as shown have not been approved by the engineering staff. Ditches are generally not acceptable and may require stormdrain piping or concrete lining. Stormwater detention shall be provided for Phase 1, 2, 3 and 4 this construction. Stormwater detention from previous phases 1 and 2 was deferred to phase 3. Current traffic count numbers for Taylor Loop are not available. Subdivision will add approximately 220 trips per day to traffic volume on Taylor Loop. E. UTILITY COMMENTS/FIRE DEPARTMENT: Wastewater: Sewer main extension required with easements. Water: water main extension required. AP&L: OK Arkla: OK Southwestern Bell: OK 2 October 10, 1996 SUBDIVISION ITEM NO.: H (Cont.) FILE NO.: S-717-F Fire Department: Turnaround for fire apparatus should be at least 50 foot radius. County Planning: No comment Lan_d_scaps : No comment F. ISSUES/TECHNICAL/DESIGN: ® Carry lot lines across open tract. a Plot rear lot lines for Phase III cul-de-sac lots. G. ANALYSIS: The developer proposes to add 10 lots in Phase 3 and another 12 lots in Phase 4. The lot configuration at the cul-de-sac on the proposed Glenstone Drive should be changed. Public Works is requiring that stormwater detention for Phases 1, 2, 3 and 4 should be provided at this time. An open tract lot was added along the western boundary of the proposed plats to accommodate drainage. H. STAFF RECOMMENDATIONS: APPROVAL of the preliminary plats. Approval is subject to the conditions listed in paragraphs D, E, and F of this staff report. SUBDIVISION COMMITTEE COMMENT: (AUGUST 8, 1996) Mr. Bill Dean, project engineer, was present to answer questions. Planning Staff noted that Phase 3 Lot 3 did not meet minimum lot depth requirements. Staff noted that street radii and right-of- ways need to be shown on the preliminary plat. David Scherer discussed drainage concerns that impacted the two existing phases as well as phases 3 and 4. He indicated that drainage was _originally planned to exit phase 2 through a pipe situated between Lots 20 and 21 then continuing off -site through an easement into a creek. This offsite easement was never obtained and the drainage structure not completed. Public Works is now requiring an above ground drainage system on an open space tract rather than an easement covering lots in Phase 2, 3 and 4. The item is to be forwarded to the full Commission for determination. 3 October 10, 1996 SUBDIVISION ITEM NO.: H (Cont.) FILE NO.: 5-717-F PLANNING COMMISSION ACTION: (AUGUST 29, 1996) Mr. Bill Dean, project engineer, requested that the two cul-de- sac streets be shown as minor residential streets. He also asked that the rear setback line along the western boundary of the subdivision be modified. This would include Lots 6-10 in Phase III and Lots 1-4 in Phase IV. The applicant is proposing to reduce the rear setback requirement for these lots from 25 feet to 15 feet. This request is in order to "...achieve the utility of those particular lots for the particular sizes of houses that are anticipated." Mr. Dean is requesting this variance in order to offset the Public Works requirement of a open tract for drainage ditch purposes.

Commissioner Adcock asked that the applicant's request a deferral. Mr. Dean requested a deferral to October 10, 1996 Planning Commission meeting.

SUBDIVISION COMMITTEE COMMENT: (SEPTEMBER 19, 1996) Mr. Bill Dean, project engineer, explained the changes in the preliminary plat that have been made since the August 29 Planning Commission meeting.

Staff supports the variance as requested. The applicant needs to show a 15 foot platted rear yard setback line on the plat. The applicant has noted that the "open tract" at the north end of the property and extending along the west boundary will be used as a drainage easement and for stormwater detention.
