Timberwood Estates 2nd Addition December 11, 1995 Page 2 PROPOSAL /SUMMARY The applicants are proposing to plat Outlot C into one lot. In 1987 when the preliminary plat for Timberwood Estates was approved, the City Council indicated the lot could be built upon if the applicant could demonstrate that the lot was buildable. To be considered a buildable lot, the applicant must demonstrate that the parcel can accommodate a home, well, and two drainfield sites which meet ordinance requirements. In April of 1994, the City changed the setback requirement for septic system drainfields from 150 feet from a wetland to 75 feet. A survey prepared for the site demonstrates that there is adequate room for a home, well, and primary and alternate drainfield sites on the property. Staff recommends approval of the final plat as the applicant has demonstrated that the lot is buildable based on current ordinance requirements. No variances are being requested. Final plats are generally treated as a consent item on the City Council agenda. Due to the amount of time between preliminary plat approval and the final platting of Outlot C, staff placed this item under New Business on the Council agenda and notified property owners within five hundred (500) feet. BACKGROUND Timberwood Estates, Subdivision #86 -27, was approved by the City Council on October 19, 1987. Outlot C was platted as an outlot because the city did not believe it could meet ordinance requirements concerning wetland setbacks and was therefore considered unbuildable. However, the Council indicated that if the applicant could demonstrate it was buildable without a variance, the city would reconsider its position. Condition four of preliminary plat approval for Timberwood Subdivision stated, "Lots 6 and 7, Block 2 (recorded as Outlot C) shall be deemed as an outlot and unbuildable, or shall be combined with adjacent lots unless and until city staff is satisfied that they are buildable." At the time of preliminary and final plat approval, the setback for a drainfield from a wetland was one hundred and fifty (150) feet. On April 25, 1994, the City Council amended section 20 -405 to read, "Septic and soil absorption systems must be setback a minimum of seventy -five (75) feet from the ordinary high water mark of the wetland." STREETS /ACCESS Access to the site will be provided via Timberwood Drive. Timberwood Drive is built to rural street standards (24 -foot bituminous /6 foot gravel shoulders with ditch section). The future driveway will require a culvert. Access off Coulter Boulevard shall be prohibited. I Timberwood Estates 2nd Addition December 11, 1995 Page 3 ' GRADING/DRAINAGE The proposed house pad is located in the southwest corner of the lot. Minimal site grading will be ' necessary to accommodate the future home and driveway. A detailed grading and erosion control plan shall be submitted to the City for review and approval prior to issuance of a building permit. A drainage easement originally covered a portion of the wetland located on Outlot C. As part of final plat approval, the applicant expanded the drainage easement to cover the entire wetland. ' ON -SITE SEWAGE DISPOSAL City staff made several on -site inspections of the property to determine the suitability of the site for septic system purposes. The primary site was evaluated and found to be acceptable. An alternate site is proposed on the north end of the property. The staked area as shown on the survey encroaches into the required wetland setback, however, the area staked is well in excess of the area ' needed to construct a system for the proposed dwelling. A six bedroom dwelling is assumed to use 900 gallons of water per day. The soils at the proposed alternate ISTS (individual sewage treatment system) site would require a maximum area of 4,200 square feet (assuming a 45 -60 mpi percolation rate). There is approximately 5,300 square feet of ' area available that is not within the required setback from the wetland. Therefore, there is sufficient area to locate the alternate site outside the wetland setback. Staff recommends that the ISTS site be re- staked and shown outside the required setback prior to recording the final plat. WETLAND The wetland is included in the National Wetland Inventory and is identified on the city's official wetland classification map. The wetland is classified as Ag/urban by the city and is wetland type PEMCd (Cowardin), type 2 (Circular 39). The wetland edge was delineated by Peterson 1 Environmental in the spring of 1995. This wetland is part of a larger wetland area that extends to the north and east from the site encompassing approximately 5.6 acres. ' Lots created after 12/14/92 shall have a buffer strip abutting the wetland. The buffer strip shall be 0 -20 feet wide with an average width of 10 feet. The lot shall be monumented at the southeast lot corner abutting the wetland. ' FINDINGS I 1. The proposed subdivision is consistent with the zoning ordinance; Timberwood Estates 2nd Addition December 11, 1995 Page 4 Finding: The subdivision meets all the requirements of the RR, Rural Residential Zoning District. The proposed lot is 5.0 acres which far exceeds the 2.5 acre minimum. 2. The proposed subdivision is consistent with all applicable city, county and regional plans including but not limited to the city's comprehensive plan; Finding: The proposed subdivision is consistent with all applicable plans including the City's Comprehensive plan which shows this area guided for large lot residential. 3. The physical characteristics of the site, including but not limited to topography, soils, vegetation, susceptibility to erosion and siltation, susceptibility to flooding, and storm water drainage are suitable for the proposed development; Finding: The proposed site is suitable for development subject to the conditions specified in this report. 4. The proposed subdivision makes adequate provision for water supply, storm drainage, sewage disposal, streets, erosion control and all other improvements required by this chapter; Finding: The proposed subdivision is served by adequate urban infrastructure. Method of sewage disposal is on -site. Adequate drainfield sites are available on the property. 5. The proposed subdivision will not cause environmental damage; Finding: The proposed subdivision will not cause environmental damage if the appropriate conditions are attached. 0 The proposed subdivision will not conflict with easements of record. Finding: The proposed subdivision will not conflict with existing easements, but rather will expand and provide all necessary easements. 7. The proposed subdivision is not premature. A subdivision is premature if any of the following exists: a. Lack of adequate storm water drainage. b. Lack of adequate roads. Timberwood Estates 2nd Addition December 11, 1995 Page 5 ' C. Lack of adequate sanitary sewer systems. d. Lack of adequate off -site public improvements or support systems. I Finding : The proposed subdivision is provided with adequate urban infrastructure. ' RECOMMENDATION Staff recommends that the City Council adopt the following motion: 1 "The City Council approves the final plat of Outlot C (Subdivision 86 -27), into Lot 1, Block 1, Timberwood Estates 2nd Addition, subject to plans Received November 27, 1995, and the ' following conditions: 1. The proposed alternate ISTS site shall be shown outside the required setbacks prior to recording the final plat. ' 2. Both ISTS sites should be roped and signed in accordance with City Policy #10 -1991. 3. Detailed grading, drainage, and erosion control plans shall be submitted to the City at the time ' of building permit application. 4. The proposed single - family residential development of 3.71 developable acres shall be responsible for water quantity and quality connection charges of $2,968.00. These fees will be due at time of final plat recording. 5. Full park and trail fees shall be paid at the time of building permit approval in the amount in force at the time of building permit application. I 6. Access shall be provided via Timberwood Drive only. Access onto Coulter Boulevard shall be prohibited. 7. Wetland buffer areas shall be surveyed and staked in accordance with the City's wetland ordinance. ' 8. The wetland edge must be included on the plat." ATTACHMENTS: 1.

" for the above referenced What is now Outlot C, Timberwood Estates was deemed unbuildable during the subdivision process in 1986 because the required 150' wetland setback left insufficient area for the two required ISTS (individual sewage treatment system) sites. The wetland setback requirements have since changed to 75'. Analvsis: The applicants originally proposed two ISTS sites along the west property line. A site inspection on 9/18/95 determined that the proposed sites likely encroached into the require setbacks. The applicant was directed to have the setbacks staked by a surveyor and propose acceptable sites. A site inspection on 10/13/95 determined that the soils were suitable for an alternate ISTS site as proposed along the north property line. The wetland setback was not staked in that area at the time, so the designer was directed to stake the proposed site and have the site added to the survey by the surveyor. The staked area as shown on the survey encroaches into the required wetland setback, however, the area staked is well in excess of the area needed to construct a system for the proposed dwelling. A six bedroom dwelling is assumed to use 900 gallons of water per day.

There is 5300 -5400 sf of area available that is not within the required setbacks for the alternate ISTS site. The primary site was also evaluated and found to be acceptable.

Final plat looks acceptable. No development contract needed. 2. Grading plan looks acceptable. The will builder will need a driveway culvert when the house is built. 3. There is no concrete curb on Timberwood. The street is built to rural street standards (24 -foot bituminous /6 -foot gravel shoulders with ditch section). 4. With the proposed house pad location, extension of utilities from Coulter Boulevard is not feasible. Also, Timberwood Estates is outside the MUSA. 5.
