RCA Exhibit A 10 � provided rationale in routing the water to Acorn Road to help the volume of water flowing in to the 102 southwest portion of the property; and with this iteration, water would leave the site very slowly and 103 infiltrate into the drainage tile system, connecting to an 8" pipe and downstream into that underground 104 system to Acorn Road. Mr. Plowe advised that the City Engineer had indicated there would be no 105 problem with this additional flow with existing stormwater management in the area. 106 Member Cunningham noted that one reason for previous proposals being ultimately denied by the City 107 Council was due to concerns with emergency vehicle access; and asked for comment on this latest 108 iteration without a cul-de-sac to facilitate that, as well as addressing whether or not widening the street to 1oG 32' would alleviate emergency vehicle access issues. 11G Mr. Plowe noted that, with this iteration, the road had been shortened 25' from the previously Planning � � 7 Commission-approved development proposal, making the actual length of the street quite short. 112 City Planner Thomas Paschke clarified that concerns were raised by an individual Councilmember or from 11� area residents, he couldn't readily remember. However, Mr. Paschke noted that the Fire Department was 1 �� part of the DRC in reviewing any proposal, and had indicated no areas of concern. Mr. Paschke advised 1 � 5 that this private street would be similar to local streets having parking on both sides, traffic, and delivery 1 � 6 vehicles all having access, in addition to being able to accommodate emergency vehicle access. 117 At the request of Member Bull, Mr. Plowe advised that, while he didn't have actual impervious surface 11� calculations available for this iteration compared to previous proposals, impervious surfaces had been 119 reduced by eliminating one proposed building site and driveway, estimating that alone would reduce it by 12o approximately 1,000 feet. 12� Developer and Property Owner Art Mueller 12� Mr. Mueller stated that the road would now be so short it was shorter than his existing driveway. Mr. 12� Mueller opined that there should be no problems for delivery or emergency vehicles; and noted that due 12� to the short private road, residents would actually haul their garbage out to Acorn Road. 125 Public Comment 126 Mr. S. Ramalingam, 2182 Acorn Road 12i Mr. Ramalingam reviewed various elevations, gradients, and his calculations with the proposed grading 128 plan and stormwater basins; and potential impacts to Mr. Irv Cross's property on the east side. Mr. 12� Ramalingam further addressed the flow moving from this site to the 8" drain into Acorn Road 13o infrastructure, and questioned if it would be able to accommodate that additional flow, seeking further 13� evaluation by the City Engineer as to how many inches per hour it could accommodate. Mr. Ramalingam 132 asked staff to further evaluate the high water level on the western basin and surrounding area and height 133 differences. 13c+ Mr. Ramalingam noted that, once all the trees were removed as proposed, there would be no longer any 135 transpiration from the property, opining that 30-40% of the property's drainage today was handled by � 3r those mature trees, and questioned how that would impact neighboring properties. 13� Member Murphy suggested the questions raised by Mr. Ramalingam would be most likely addressed by 13n the city's engineering staff. 13� Member Bull noted that engineered soils in the ponds should address that based on their understanding. 14G Mr. Ramalingam opined that engineers were addressing low, not high water levels; and groundwater was 14� an unknown in the equation. However, Mr. Ramalingam further opined that the grading plan indicated the 142 basins would be higher than Mr. Cross's property and the water had to go somewhere and based on his 143 calculations, it was currently going to the Cross property. 14�? Mr. Ramalingam further addressed the 32' width of Acorn Road with no parking, while this private street, 145 while short will have parking on both sides; and sought a guarantee that emergency vehicles would be 146 able to access properties or turn around. 14,� Janet Romanowski, 2195 Acorn Road 1�8 In listening to tonighYs conversation, Ms. Romanowski noted there still appeared to be problems with ,� drainage, then homeowner's association and tree removal, as well as the private road and parking and Page 12 of 15
