Description: 111 residential lots on 23.02 acres
Background:
Hidden Springs Subdivision is located at the intersection of Highway 46 South and Saengerhalle Road. A master plan was approved in February, 2019.
The preliminary plat for Unit 1 contains 111 residential lots meeting the dimensional requirements for “ZH-A” Zero Lot Line Home District. Two points of access are being platted from Saengerhalle Road, and a street projection to adjacent unplatted property (Street F) is provided to meet the connectivity and block length requirements.
Drainage:
The City’s Engineering Division reviewed the preliminary drainage report as required by Section 118-51e of the Platting Ordinance and in accordance with the requirements of Chapter 143 Municipal Drainage Utility Systems, and the Drainage and Erosion Control and Design Manual.
The report intends to meet the requirements of Sec. 143-20, allowing for stormwater connection fee in lieu of detention by way of 3,000-foot downstream analysis. However, the report as presented does not include sufficient detail to confirm compliance with the code. Final review will occur with the construction plans that must be submitted and approved prior to the submittal of the final plat.
No portion of the property is located within the 100-year floodplain. However, per Sec. 118-51(f)(3), if a proposed subdivision is within an area where flooding may occur, where there is no floodplain shown on a city-approved floodplain map the subdivider shall conduct a study to determine where the base flood elevation would be, assuming a fully developed watershed, show a drainage easement on the plat, and show the elevation of the flood plain at intervals of every 500 lineal feet.
Utilities:
Electric, water and sewer services will be provided by New Braunfels Utilities. Utilities will be extended by the developer and approval of construction plans is required prior to submitting a final plat. NBU has identified water capacity issues in the area and notes that preliminary plat approval does not constitute reservation of water capacity. Water capacity is only reserved upon construction plan approval.
Transportation:
Regional Transportation Plan:
Saengerhalle Road is identified as a 120-foot wide Minor Arterial and the current right-of-way width is approximately 70 feet. A variable width right-of-way dedication is indicated on this plat. Actual dedication of right-of-way will be made with the final plat.
Hike and Bike:
The City’s Hike and Bike Trail Plan indicates a trail along Three Mile Creek, crossing the subject property and following Saengerhalle Road to Highway 46. The portion of the trail along Saengerhalle Road is within Unit 1 and will be constructed by the developer as a 10-foot wide shared use path at the time of subdivision construction. The remainder of the trail is located in Unit 3.
Sidewalks:
Four-foot wide residential sidewalks will be constructed along all internal streets, by the homebuilder on residential lots and by the developer at the time of subdivision construction on non-buildable lots. The shared use path will serve as the required sidewalk along Saengerhalle Road.
Roadway Impact Fees:
Roadway impact fees for Service Area 6 will be assessed with approval of the final plat. Impact fees are collected at time of building permit as indicated in the then current fee schedule.
Parkland Dedication and Development:
This subdivision is subject to the Parkland Dedication and Development Ordinance. Fees in lieu of dedication and development will be paid prior to recording the final plat. The Parks and Recreation Department will review any proposed recreational amenities with the final plat and determine whether a portion of the fee is eligible for reimbursement.
Staff Recommendation:
Staff recommends approval with the following requirements needed to meet the Platting Ordinance:
1. Street name approval prior to submission of construction plans.
2. Provide updated preliminary plat with approved street names prior to submission of construction plans.
3. Create a separate lot for the subdivision entry sign rather than an easement within the drainage lot.
4. Provide additional drainage information with construction plans for the area where flooding may occur.
