North Hills 10th Development Pre-approval synopsis

• Project: North Hills 1st Addition (Preliminary Plat #26001) 

• Size: ~15.4 acres 

• Zoning: R-3 Residential (matches surrounding area) 

• Context: Previously planned for a school site, now converted to residential 

• Compatibility: Approved as consistent with Lincoln’s 2050 Comp Plan 

👉 Key Point:
This is an infill residential conversion, not a brand-new subdivision concept.

⚠️ Conditions of Approval as of this meeting

City required:

• Updated plat with:

  • Street bearings/distances

  • ROW clarity

  • Sidewalk accessibility (PROWAG) 

• Drainage plan revisions still pending approval

👉 Key Condition:
This project is not fully approved yet—details can still shift.

🏗️ Key Development Constraints

1. Sewer challenges 

• Sewer runs opposite street grade (not typical) 

• Sewer depth exceeds standard limits

• Reason:

  • Existing downstream connections

  • Site boxed in by existing homes

  • Can’t route through private property

👉 Key Point:
This site is engineering-constrained, not optimized from scratch.

2. Waivers granted

• Sewer depth waiver

• Sewer direction waiver 

🗺️ Streets & Layout 

Major Streets Identified:

• Folkways Blvd (south boundary)

• N. 18th Street (west edge)

• Internal streets:

  • Rockford Dr

  • Shooting Star Dr

  • Morton Street 

👉 Layout takeaway:

• Standard neighborhood grid with curving residential streets

• Connects cleanly into existing North Hills system

🏡 Lot Layout & Dimensions 

Typical Lot Widths:

• 50–60 ft = most common

• Some larger 65–75 ft lots

• A few irregular / wider lots (100–130 ft depth)

👉 Key Points:

• This is a mid-density single-family layout

• Mix of:

  • Standard builder lots

  • A few premium or corner lots

Pattern:

• Depths ~120 ft dominate

• Some compressed lots (~100 ft)

• Occasional oversized parcels

👉 The Neighborhood will likely see:

• Mix of home sizes

• Some higher-value lots along edges/curves

🌧️ Drainage & Water Management

Pond + Stormwater System

Pond 01 (Main Feature)

• Designed for:

  • 2-year, 10-year, 100-year storms

• Key numbers:

  • 100-year peak flow: 67.45 cfs in / 33.02 cfs out

• Water elevations:

  • Base: 1219

  • Normal water: 1223

  • Overflow crest: 1226 

Construction details:

• 4:1 side slopes (fairly standard, mowable)

• Outlet uses orifice plate system (6 holes)

• Connected via:

  • 24” reinforced concrete pipe

  • Concrete control box 

👉 Key Points:

• This is a managed detention basin, not just a pond

• It actively controls:

  • Flooding

  • Water quality

• Will likely be a visible feature

Grading & Drainage Plan

• Site divided into drainage areas (~5 acres each)

• Extensive storm sewer network + structures

• Minimum building opening elevation ~1227 ft for multiple lots 

👉 Key Points:

• Homes will be elevated relative to pond

• Drainage is carefully engineered → for flooding control

📏 Elevation & Terrain

• Elevation range roughly:

  • 1210 → 1250 ft across site 

👉 Key Point:

• Moderate slope—not flat

• Explains:

  • Complex drainage system

  • Sewer challenges
