Land Development Playbook

o Design and install dry utilities (power, gas, & communications) on the garage side of the lot. All homes are to be plotted garage-to-garage, when possible, to allow for utility stubs to be at every other property line rather than every PL, reducing the number of service stubs. This approach adds efficiencies in trenching and installation as well as consolidating equipment above ground. o Design and install water meters on the opposite PL from dry utility stubs to avoid conflicts and a single trench for two lots. This will allow for a single trench to home both water services (when allowable by the district) again minimizing the scope of work and adding efficiency. o Design and install sewer services 10’ from water or center of lot if driveways allow. Avoid planned drive locations, as some jurisdictions do not allow cleanouts in the driveway. Health and safety regulations vary from 5’ to 10’ separation between water and sewer. Standardizing at 10’ separation allows for consistency in the field when locating buried services. o Whenever possible, design and install sewer laterals with above-ground risers to identify the lateral and allow for the plumber to tie into that riser at the proper depth without digging to the depth of the lateral itself. Basements do not apply to this practice, but services are to be clearly marked to avoid damage during basement excavation. Base lot standards are to be included as an exhibit in every lot contract and should be initiated as an attachment starting with the LOI process. As the design progresses in project plan development, lot standards are referenced by the design team. Use NLD’s CAD Lot standards on plan sheets to allow for the insertion of typical lot details in every grading plan set to ensure conformance to standards at the time of design. The design and permitting process, along with unique site conditions, may create exceptions on certain lots, which should be reviewed and documented by a Land Development Professional on the project team (with inter-divisional coordination as needed). As home construction on finished lots occurs after mass grading has been completed, the volume of dirt needed on a lot-by-lot basis needs to be managed to minimize vertical coordination of earthwork site vendors, as this leads to higher dirt costs, additional roadway and curb damage, and an increase in erosion control risk.

CONSTRUCTION TURNOVER

A When delivering Finished Lots (as designed in the required lot-fit plan) to our homebuilding teams, LD and vertical construction teams are to walk the project site to confirm all improvements are completed and establish a written punch list for any incomplete items. A The LD team will complete the punch list, and vertical construction will confirm the punch list has been completed before accepting ownership of the site. This process establishes the transfer of responsibility for operating and maintaining the project site, including, but not limited to, site cleanliness, material storage, security, SWPPP, damage, and replacement of all existing improvements, etc. A If a Third-Party Developer is unable or unwilling to meet Century’s definition of a Finished Lot, then our internal LD teams need to address that work before the community is turned over to our vertical construction team.

IMPORTANT: Whether we are self-developing our own lots or purchasing “Finished Lots” from a Third-Party developer, our lot standards and/or the condition that we deliver lots to our vertical construction teams will be the same. The same can be said for public utilities that we turn over to the municipalities and the amenities that we turn over to the HOA.
