About this file
This civil plans document for the Cauley Creek Park Parking Lot Addition project was prepared by CHA Companies for the City of Johns Creek, Georgia, and approved on February 22, 2026. The project encompasses the construction of an overflow parking lot with 87 parking spaces at 7255 Bell Road, Johns Creek, Georgia 30097, involving grading, subgrade preparation, installation of graded aggregate base, asphalt placement, and landscaping. The civil plans include comprehensive site plans, grading and utility plans, stormwater management details, erosion and sedimentation control measures, and landscape specifications across multiple drawing sheets. The project involves three construction phases with detailed erosion and sediment control plans required throughout. Key site features include two sedimentation basins (Basin A at 1.37 acres and Basin B at 0.23 acres), a bioretention basin with engineered soil media 36 inches thick, a 4-inch perforated underdrain system, and stone outfall structures. The project must comply with Georgia's stormwater pollution prevention plan (SWPPP) requirements and conservation commission standards for erosion control, with all erosion control measures to be maintained at all times and any disturbed areas left exposed for more than 14 days to be stabilized with mulch or temporary seeding.
The plans specify detailed material requirements including engineered soil mix for the bioretention area (sandy loam or loamy sand with specific sand, fines, topsoil, and compost content), Class A concrete (3000 PSI at 28 days) for pavement, and TifTuf Bermuda grass sod for turf areas. Landscaping includes the planting of 5 Built to Last Red Maple trees and 9 Nuttall Oak trees, with removal of existing trees and plantings as necessary for sidewalk installation. The site operator and general contractor is identified as the City of Johns Creek with Matthew Pate listed as superintendent, reachable at 678-512-3261. The developer and owner address is listed as 11360 Lakefield Drive, Johns Creek, Georgia 30097. The project site is located adjacent to existing wetlands and within proximity to Cauley Creek, the identified receiving water for stormwater runoff. The plans include detailed specifications for silt fences, sediment traps, temporary seeding schedules, and comprehensive maintenance and inspection protocols for erosion and sediment controls throughout all project phases.

MANAGEMENT PLAN
ENGINEERED SOIL MIX
Engineered soil mix for use in areas having calculated stormwater performance values and shall consist of a mixture of sand, clay, silt and organic matter meeting the following specifications:
Classified as a sandy loam or loamy sand
Sand Content: 70-80% clean washed sand (dry weight basis), conforming to the gradation requirements for fine aggregate in ASTM C 33
Fines (Clay and Silt) Content: Not greater than 10% including topsoil (dry weight basis)
Topsoil: 10-20% (dry weight basis)
Compost: 5-10% (dry weight basis)
Infiltration rate: At least 1 inch per hour, and preferred rate of 1-2 inches per hour (as determined using ASTM D 3385 or other approved test method) pH: 5.5 to 6.5 (as determined using ASTM D 4972)
Organic Content: 3-10% (as determined using ASTM D 2974 or other approved test method)
Concentration of Soluble Salts: Not to exceed 500 ppm (as determined using ASTM D
4542)
BIORETENTION GRASS MATERIALS:
Provide machine_cut, strongly rooted, certified turf grass sod, at least 18 months old and free of weeds, non-organic contaminants and undesirable native grasses. Provide sod capable of vigorous growth and development when planted and complying with the following requirements:
Sod shall consist of 100% TifTuf Bermuda. Contractor shall submit supplier for approval by owner.
Sod roll shall be uniform thickness of 1.2" inch, plus or minus 1/8 inch (.31cm), measured at time of cutting and excluding top growth and thatch. Provide turf that measures a minimum of 24 inches wide and 50 feet in length. Broken or torn rolls or rolls with uneven ends are not acceptable. Provide sod pads capable of supporting their own weight and retaining size and shape when supplier's standard size pad is suspended vertically from a firm grasp on upper 10 percent of the pad.
Sod must be grown on a sand-based soil (sandy loamy sand or sandy loam). Sod grown on a muck soil bed is not allowed.
