FT. NEW STREET: 14,835 LF A. PROPOSAL/REQUEST/APPLICANT'S STATEMENT: The project lies in the City of Little Rock's Extraterritorial Planning Jurisdiction and is located in Pulaski County. 266 residential lots are proposed. The plat indicates 188 lots with a minimum square footage of 7,000 square feet up to 15,000 square feet and 78 lots ranging from 15,000 square feet to 98,000 square feet. The subdivision is proposed in six (6) phases. The plat indicates a bike lane along "Nature Trail" running from the eastern access on Kanis Road approximately 1 '/4-miles to the second access (western) on Kanis Road near Walnut Valley Road. The subdivision is proposed with multiple internal greenways coupled with walking trails. The greenways provide January 7, 2016 SUBDIVISION ITEM NO.: D (Cont. FILE NO.: internal natural areas that will be interwoven with the new housing areas. The trails will connect to four (4) pavilions located within the greenway areas. The subdivision will contain 14,800 linear feet of roads constructed with full curb and gutter with a five (5) foot wide sidewalk on at least one (1) side of all roads. The exception to this is for the street along the ridge which will be constructed with trails in -lieu of sidewalks. The roads will all be constructed with a minimum of 28-feet back to back of curb on all roads with the exception of Nature Trail. Nature Trail will be constructed 33-feet back to back of curb to accommodate 2-bike lanes. The concrete curb and gutters along the sides of the roads will convey stormwater to intermediate storm drains and manholes and subsurface storm water piping system. The piping will subsequently convey the majority of the stormwater to a series of two (2) detention ponds. Two (2) entrances/exits are proposed to connect with Kanis Road on the eastern and western extents of the subdivision. These entrances/exits will be constructed with a 15-foot widened pavement width for 150-feet in length adjacent to Kanis Road. These entrances have been located to provide safe ingress and egress for the subdivision. Site distance studies will be conducted and provided for review during the design process for the subdivision. Electrical service will be provided via underground lines. Water will be provided via connections to Central Arkansas Water and natural gas will be provided throughout the subdivision. As a separate item on this agenda the applicant is requesting approval of a Conditional Use Permit to allow for the proposed wastewater treatment. Wastewater will be collected via combination of gravity collection sewer and tight line forced mains and conveyed to a packaged treatment plant located south of the larger of the two (2) ponds. The plant will utilize the biological extended aeration principle of operation, a variation of the activated sludge process. The discharge of the plant will be released into the adjacent larger pond. The flow from the spillway of the larger pond will ultimately discharge into Fletcher Creek to the west of the pond. The plant will be recessed below grade for aesthetics and noise control. The wastewater treatment plant will be designed, permitted and constructed in accordance with requirements of the Arkansas Department of Health and the Arkansas Department of Environmental Quality (ADEQ). A large site Stormwater Pollution Prevention Plan will be developed for this site in accordance with the requirements of NPDES and ADEQ and submitted to ADEQ for review and approval. The plan will be implemented and strictly adhered to throughout the entire life of the construction process and detention maintained permanently upon completion of the construction. 051 January 7, 2016 SUBDIVISION ITEM NO.: D Cont.)

SUBDIVISION COMMITTEE COMMENT: (September 16, 2015) Mr. Phillip Lewis and Mr. Wayne Richie were present representing the request. Staff presented an overview of the item stating the original application filed included a request to rezone the site to Planned Development Residential and a companion application for a conditional use permit to allow the placement of a wastewater treatment system to serve the new lots. Staff stated the applicant 11 January 7, 2016 SUBDIVISION ITEM NO.. D(Cont.)FILE NO.: 5-1758 was no longer requesting to rezone the property and had submitted a request to withdraw the Planned Development application request. Staff stated the applicant was seeking preliminary plat approval for a single-family subdivision. Staff stated the plat as presently submitted included variances for lot depth to width ratio. Staff stated the plat also included a reduced front building line on a few of the lots. Mr. Lewis stated he would review the plat and make adjustments accordingly. Public Works comments were addressed. Staff requested Mr. Lewis provide the centerline profiles for the proposed streets. Staff also stated the acceleration and deceleration lanes on Kanis Road should not be constructed. Staff stated grading permits were required prior to any clearing on the site. Staff stated stormwater detention would apply to the property. Staff stated on streets 24-feet in width parking was restricted to one (1) side only. Staff requested Mr. Lewis provide a note on the plat and include the language in the bill of assurance for the subdivision concerning the limits on street parking. Staff noted comments from County Planning and suggested Mr. Lewis contact them directly. Staff also requested Mr. Lewis provide the County Planning office with all correspondence provided to the City. Staff noted the comments from the various other agencies. There were no more issues for discussion. The Committee then forwarded the item to the full Commission for final action. K ANALYSIS: The applicant submitted a revised preliminary plat to staff addressing a number of the issues raised at the September 16, 2015, Subdivision Committee meeting. The applicant has revised the preliminary plat and has increased the building line to a minimum of 25-feet on all the proposed lots. The request is to allow the development of a single-family subdivision containing 266 residential lots developed per the R-2, Single-family zoning district. The zoning district has minimum development standards for lots developed within the City's Extraterritorial Planning Jurisdiction. Section 31-232 states except as provided herein, the minimum lot dimensions shall conform to the requirements of the zoning ordinance for areas zoned within the jurisdiction. Within the extraterritorial planning jurisdiction not currently zoned, the following minimum lot dimensions shall prevail: single-family detached residential lots are to be 60-feet by 100-feet. Section 31-232(b) states no residential lot shall be more than three (3) times as deep as it is wide, except lots approved under paragraph (g) or zero lot line lots in the R-2, R-3, PRD and PD-R zoning districts. No lot except lots designated for townhouse use shall average less than one hundred (100) feet in depth. Lot 12 January 7, 2016 SUBDIVISION ITEM NO.: D (Cont.) FILE NO.: S-1758 width shall be measured at the building line except in the case of a lot abutting a cul-de-sac where the average width of the lot shall be used. The revised preliminary plat has corrected the depth to width ratio for most of the lots. A few of the lots are still indicated with the variance which exceed the 3:1 ratio for depth to width. The lots are located adjacent to green spaces. The applicant has stated prior to submission of the preliminary plat for approval by staff if/and when the Commission approves the request all variances will be eliminated. There are lots abutting Kanis Road which have frontage on both Kanis Road and the new street running along the ridge of the subdivision. Section 31-232(d) states double frontage lots are prohibited. However, where a subdivision abuts or contains an existing or proposed arterial street, freeway, expressway, or railroad right-of-way, reverse frontage lots are permitted. Double frontage lots may also be used to facilitate residential development in hillside areas as defined in Division 8, Section 31-367, of the subdivision ordinance. Section 31-257, double frontage lots, states along arterial streets in proposed subdivisions where it is desirable to limit curb cut access, building lines shall be established on both frontages of double frontage lots. Along the line of lots abutting such traffic artery, a restricted access easement of at least ten (10) feet, across which there shall be no right -of -vehicle access permitted, shall be provided. The plat has not included the no right of vehicular access easement which will be included on the preliminary plat to be submitted for final signature upon approval. Section 31-256 outlines the criteria for building lines on residential lots. The ordinance states building lines for residential lots shall be at least twenty-five (25) feet from each street property line except in the following circumstances: (1) Residential lots fronting on collector streets shall have a platted building line not less than thirty (30) feet from the right-of-way line. (2) Residential lots fronting on a minor arterial street shall have a platted building line not less than thirty-five (35) feet from the right-of-way line. (3) Lots fronting on culs-de-sac or curved portions of other streets may provide a front building line that is straight relative to the front property line. This line is to be established by placement of dimensioned points on the side property lines at least thirty-two (32) feet from the street right-of-way line and connecting these points with a dimensioned straight line on the plat. This line shall not be less than twenty-five (25) feet from the street right-of-way line at any point. The plat as submitted includes the required building setbacks. Section 31-175 provides the guidelines for sidewalk construction. The ordinance allows subdivisions to provide internalized pedestrian circulation system in the form of paved pathways in -lieu of sidewalks along collector and residential street classifications upon the request of the applicant and the approval of the Planning Commission. The plat includes trails within the subdivision in -lieu of sidewalks in a number of locations. 13 January 7, 2016 SUBDIVISION ITEM NO.: D (Cont. FILE NO.: S-17 The plat includes larger ridge lots and smaller valley lots. The plat includes 78 lots ranging from 15,000 square feet to 98,000 square feet. The plat includes 188 lots ranging in size from 7,000 square feet to 26,000 square feet. The development is proposed in multiple phases. The street improvements to Kanis Road are also proposed to be phased with the development of the lots. The Phase 1 portion of the development includes 30 lots. Phase II includes the development of 30 lots. 43 lots will be developed in Phase III and 43 additional lots in Phase IV. Phase V includes 36 lots, Phase VI includes 17 lots and the final, Phase VII, includes 17 lots. Street improvements to Kanis Road will be phased with the development of the subdivision. The improvements to Kanis road include widening the street to an eleven (11) foot drive lane with a four (4) foot paved shoulder as required per the Master Street Plan. The plan also includes paving a five (5) foot shoulder at the entrances to the subdivision to allow for a turning lane on Kanis Road as requested by staff. The ridge road will be constructed with two (2) eleven (11) foot drive lanes, two (2) six (6) foot bike lanes and additional right of way on each side of the street eight (8) feet wide. The internal residential streets are proposed with two (2) drive lanes 13.5-feet in width and two (2) 11.5 foot shoulders. The plat indicates the dedication of an additional 15-feet of right of way along Kanis Road to meet the Master Street Plan. Half street improvements to Kanis Road will be completed with the corresponding phase along Kanis Road, Phases I, II, VII. All improvements will be completed prior to final platting of the next to last phase of the development. The required right of way dedication for Walnut Grove Road will be provided with the development of the subdivision. Improvements to Walnut Grove Road will be constructed at the time required by the City and/or County or prior to the final plat approval of Phase VII. A large stormwater pollution prevention plan will be required for the project and will be subsequently developed in accordance with NPDES and ADEQ requirements and submitted to ADEQ, the City of Little Rock and Pulaski County Planning for review and approval. Prior to the issuance of a grading permit all regulatory agencies will be provided a copy of the final grading and drainage plan for review and approval. No development of the site will occur without approval from all reviewing bodies. A Conditional Use Permit request for a package treatment plant is a separate item on this agenda. The package treatment plant will utilize the extended aeration principle of operation (variation of the activated sludge process). The discharge of the plant will be into the larger pond proposed for the subdivision. The plant will be constructed below grade. The plant will be permitted through the Arkansas Department of Environmental Quality and the Arkansas Department of Health. 14 January 7, 2016 SUBDIVISION ITEM NO.: D (Cont) FILE NO.: S-1758 Staff is supportive of the applicant's request. The variances associated with the depth to width ratio indicated on the plat are "fixable" and will be corrected to come into full compliance with the minimum standards of the City's Subdivision Ordinance prior to the issuance of the final approval of the preliminary plat. The final approval of the preliminary plat will also include the placement of a ten (10) foot no right of vehicular access easement along the rear of the lots with two (2) street frontages. To staff's knowledge there are no remaining outstanding technical issues associated with the request. STAFF RECOMMENDATION: Staff recommends approval of the request subject to compliance with the comments and conditions as outlined in paragraphs D, E and F of the agenda staff report. PLANNING COMMISSION ACTION: (OCTOBER 8, 2015) Commissioner Berry stated in light of the deferral of the companion application, the Conditional Use Permit, he felt the preliminary plat request should also be deferred to allow the applications to be considered by the Commission on the same public hearing date. Commissioner Berry made a motion to defer the preliminary plat request to the January 7, 2016, public hearing. The motion carried by a vote of 8 ayes, 0 noes, 2 absent and 1 abstention (Commissioner May). STAFF UPDATE: The applicant submitted a request dated December 23, 2015, requesting withdrawal of this item without prejudice. Staff is supportive of the withdrawal request.
