c La Porte Golf Community • SCU03-002 August 27, 2003 Page 3 of 6 development ratio of 4.8 units per acre to approximately 120 acres, this . ~ property may yield approximately 576 dwelling units. This current plan designates seven sections of single-family residential with average lot size of 60'x110'. (Larger lots are proposed abutting the .City's Golf Course.) The total number of single-family residential lots equals 444 with a density of 3.7 units per acre. ~ This density is considerably less than the 4.8 units per acre allowed in R-1 zoning districts. . • Utilities -There are sufficient water distribution facilities along frontage road of SH. 146 and McCabe Road to supply potable water and fire protection to this proposed project. Provisions will have to be made to ensure that sufficient utility extensions can be made to serve the whole . ~ development. Currently, sanitary sewer service is not available to this site; however, as a part of the City's master sewer plan for the area, ~~ easements were secured to provide a 24" trunk main. The plan provides for two possible sites for a tie in just near Popular Cove and Little Cedar. The Developer, through a Sewer Utility Agreement, should commit to paying for the sanitary sewer services and improvements needed to provide sewer service to this project and be responsible for the on-site improvements needed to serve this project. The Developer's participation may be an eligible expense with the TIRZ that allows the developer to seek reimbursement. • Drainage -The proposed development lies within the Taylor Bayou Watershed and T1RZ #1. ~ The channel improvements cannot directly receive stormwater runoff from this development. A solution is to provide stormwater detention within this development. The proposed layout depicts several reserves along eastern boundary of the development adjacent to the golf course. These reserves are intended ' - to provide the drainage and detention for the full development. The developer's layout for drainage and detention is quite similar to the layout. contained in the Taylor Bayou Drainage Master Plan. The Master Plan shows anorth-south channel conveying storm water downstream to a detention pond that is less than the one provided by the developers. This layout shows wider channel areas serving as additional buffer for the golf course. The layout also shows that ~ 15 acres (Reserve Z) of off site detention is being used to meet all the storm water management `needs. Additional information is needed to determine if the Developer owns this property and/or if the Developer has secured the necessary easements from the current property owner to use this land. These constant level ponds could also increase aesthetics for adjacent homeowners and users of the pedestrian trails. However, Staff suggests wrought iron fencing along the detention areas to prevent free movement of pedestrian traffic between the golf course and the subdivision. Detention basins design and calculations will be reviewed thoroughly to ' ~ make sure that water is retained sufficiently to prevent flooding on the golf course and the subdivision. In addition, the Commission may wish to determine, in a development agreement, the party that shall be
